In order to better understand the embodiments of the present application, the following terms refer to the embodiments of the present application:
scheduling Request (SR) is a way for a terminal Equipment (UE) to apply for resources to a network side for new data transmission. The SR message transmitted by the UE is transmitted through a Physical Uplink Control Channel (PUCCH) Control Channel. After the network side successfully decodes the SR message of a certain UE, the RB resource may or may not be allocated to the UE through Downlink Control Information (DCI). Many times, the UE needs to send the SR message multiple times in order to obtain the uplink resource. In this embodiment, after the UE sends the SR message, the UE may be triggered to enter an awake state (which may also be referred to as an active state). The UE in the awake state may monitor a Physical Downlink Control Channel (PDCCH), where the PDCCH may include the DCI, and the DCI may enable the UE to acquire the RB resource to send uplink data. After entering the awake state, the UE may start a timer, and wait for uplink scheduling of the network device during the timing process of the timer. If the timer is overtime and the scheduling of the base station is not received, the UE may send the SR message again. In the embodiment of the application, the terminal device may send the SR message in the sleep state, and after sending the SR message, the terminal device may start a timer and enter the wake-up state to monitor the corresponding PDCCH; when the timer runs out of time, the terminal equipment can enter a dormant state.
Discontinuous Reception (DRX) is a packet-based data stream that is typically bursty, with data transmission during one period, but not during the next longer period. When no data is transmitted, the power consumption can be reduced by stopping receiving the PDCCH (at the moment, the PDCCH blind detection is stopped), so that the service time of the battery is prolonged. Fig. 1 is a schematic diagram illustrating a discontinuous reception period. The period of time identified as "On Duration" is the time that the UE monitors the PDCCH, during which the UE is awake. The period of time identified as "Opportunity for DRX" is the DRX sleep time, i.e., the time the UE enters a sleep state without monitoring the PDCCH for power saving. As can be seen from fig. 1, the longer the time for DRX sleep, the lower the power consumption of the UE, but correspondingly, the delay of traffic transmission will increase. The awake state may be an On Duration state or a DRX On state. Wherein, the On Duration state may be controlled by a Duration timer (Drx-OnDurationTimer), and the Drx On state may be controlled by one or more of the Drx-OnDurationTimer, the inactivity timer (Drx-inactivity timer), a Drx downlink retransmission timer (Drx-retransmission timer) and a Drx uplink retransmission timer (Drx-retransmission timer ul).
An SR-prohibit timer (SR-prohibit timer) is used to control the frequency of SR messages transmitted in the PUCCH, which cannot be transmitted when the timer is running, and once the timer expires, the UE needs to retransmit the SR message. The operation duration of the SR-prohibit timer may be configured by Radio Resource Control (RRC).
In order to better understand the embodiments of the present application, a network architecture to which the embodiments of the present application are applicable is described below.
Referring to fig. 2, fig. 2 is a schematic diagram of a wireless communication network architecture according to an embodiment of the present disclosure. As shown in fig. 2, the network architecture may include a network device and a terminal device, and the terminal device establishes a connection with the network device through a serving cell. The serving cell may include one or more channels as a data transmission medium between the network device and the terminal device, for example, a Physical Downlink Control Channel (PDCCH), a Physical Downlink Shared Channel (PDSCH), a Physical Uplink Control Channel (PUSCH), and the like. The network device may allocate radio resources to the terminal device for traffic transmission between the network device and the terminal device.

The EPC may be composed of an MME providing functions such as mobility management, gateway selection, etc., a Serving Gateway (S-GW) providing functions such as packet forwarding, etc., and a PDN Gateway (P-GW) providing functions such as terminal address allocation, rate control, etc.

In order to reduce power consumption when a terminal device performs scheduling, embodiments of the present application provide a scheduling method and apparatus, and details of the scheduling method and apparatus provided by embodiments of the present application are further described below.
Referring to fig. 3, fig. 3 is a schematic flowchart of a scheduling method according to an embodiment of the present application. The scheduling method includes operations 310 through 340 as follows. The method execution main body shown in fig. 3 may be a terminal device or a chip in the terminal device. When the terminal device executes the flow shown in fig. 3, the following steps may be included:
310. and transmitting a Scheduling Request (SR) message in the current discontinuous reception period.
Wherein the Discontinuous Reception (DRX) period may be configurable (e.g., through RRC signaling). In this embodiment, the terminal device may send an SR message in both the awake state and the sleep state in the DRX cycle.
320. A first timer is started.
Alternatively, the first timer may be a scheduling request prohibit timer SR-ProhibitTimer.
Alternatively, the first timer may be a scheduling request decision timer.
330. And monitoring a Physical Downlink Control Channel (PDCCH) in the running process of the first timer.
Optionally, when the first timer is an SR-ProhibitTimer, after the terminal device sends the SR message, the SR-ProhibitTimer may be started. In the SR-ProhibitTimer operation process, the terminal device may monitor the PDCCH, but does not send the SR message. The operation duration of the SR-ProhibitTimer may be configured by the access network device or the terminal device, and is not limited.
Fig. 4 is a schematic diagram illustrating a method for sending an SR message when a first timer is SR-ProhibitTime. In fig. 4, the terminal device transmits an SR message in one DRX cycle, where the time for transmitting the SR message may be any time in the DRX cycle. That is, the terminal device may transmit the SR message in the DRX ON state or the DRX OFF state in the DRX cycle. It can be understood that, in the embodiments of the present application, a time when the terminal device first transmits the SR message in one DRX cycle is not limited.
Alternatively, when the first timer is a scheduling request judging timer, the terminal device may start the scheduling request judging timer after transmitting the SR message. The scheduling request judging timer may include one or more SR-prohibittimers, and the operation duration of each SR-ProhibitTimer is less than the operation duration of one scheduling request judging timer. The terminal device may monitor the PDCCH during the operation of the scheduling request determining timer, and send an SR message to the network device after each SR-probibittimer runs out. Wherein the SR-ProhibitTimer is started after the SR message is sent, and one or more SR-prohibittimers are run in the scheduling request decision timer.
Fig. 5 is a schematic diagram illustrating a method for sending an SR message when a first timer does not schedule a request determination timer. In fig. 5, one scheduling request decision timer includes two SR-prohibittimers, i.e., a first SR-ProhibitTimer and a second SR-ProhibitTimer. Of course, in practical applications, one SR-tti may include two or more SR-prohibit timers, which are only exemplary and not limiting. The terminal device transmits the SR message in one DRX cycle, wherein the time of transmitting the SR message may be any time in the DRX cycle. That is, the terminal device may transmit the SR message in the DRX ON state or the DRX OFF state in the DRX cycle. After the SR message is sent, the terminal device may start the scheduling request determination timer and simultaneously start the SR-ProhibitTimer. The operation duration of a scheduling request decision timer may be greater than or equal to the sum of the total operation durations of the one or more SR-prohibit timers. In the operation process of the scheduling request judging timer, the terminal device can monitor the PDCCH, and only when the SR-ProhibitTimer is overtime, and the scheduling request judging timer is still in the operation process, the terminal device can send the SR message again. For example, at an instant after the first SR-ProhibitTimer runs out of time, the terminal device may send the SR message again, and then start the second SR-ProhibitTimer. When the second SR-ProhibitTimer runs overtime, the scheduling request judgment timer also runs overtime, so that the terminal device suspends the SR message transmission.
340. And if the uplink authorization in the PDCCH is not monitored in the running process of the first timer and the second timer does not time after the running of the first timer is overtime, the SR message is sent again after the next discontinuous receiving period is reached.
The uplink grant is used for responding to the SR message sent by the terminal device, that is, the network device has agreed the scheduling request of the terminal device, and may allocate resources to the terminal device for performing the service transmission in response.
Wherein the second timer may comprise one or more of the following timers:
a duration timer (Drx-OnDurationTimer);
a inactivity timer (Drx-inactivity timer);
a discontinuous reception downlink retransmission timer (Drx-retransmission timerdl);
a discontinuous reception uplink retransmission timer (Drx-retransmission timer ul).
As shown in fig. 4 and 5, the running period of the second timer may be during an awake state, i.e., a DRX On period, and when the second timer is running, the terminal device is in a DRX On state.
If the uplink grant in the PDCCH is not monitored in the operation process of the first timer, it indicates that the network device does not respond to the SR message sent by the terminal device temporarily, and therefore the terminal device needs to send the SR message again. At this time, the first timer has run overtime and the second timer is not timed, which indicates that when the first timer runs overtime, the terminal device is in the DRX OFF state, i.e. the access network device cannot send the SR message in the current DRX cycle any more. Therefore, the terminal device needs to wait for the next DRX cycle before it can send the SR message again.
Optionally, if the terminal device receives the first indication signaling during the operation of the first timer, the terminal device stops operating the current first timer. The first indication signaling may be carried by physical layer signaling or the first indication signaling may be carried by MAC layer or higher layer signaling. The first indication signaling may be a physical layer signaling sent by the network device, and the terminal device may enter a dormant state after receiving the first indication signaling, and stop monitoring the PDCCH. For example, when the network device detects that no available resource can be allocated to the terminal device at this time, a first indication signaling may be sent to the terminal device, instructing the terminal device to suspend monitoring the PDCCH. Therefore, unnecessary PDCCH monitoring time of the terminal equipment can be shortened, and the power consumption of the terminal equipment is saved.
Optionally, the first indication signaling may be used to indicate that the SR message is transmitted again after the next DRX cycle arrives, that is, at the starting time of the next DRX ON state, the terminal device may transmit the SR message again. For example, the network device detects that no available resource can be allocated to the terminal device at this time, and there is not enough buffer space to buffer the SR message transmitted by the terminal device, and then the terminal device may be instructed to transmit the SR message again at the next DRX ON state.
Alternatively, the first indication signaling may be used to indicate that the SR message is suspended from being transmitted after the next DRX cycle arrives, i.e. at the start of the next DRX ON state, the terminal device may not have to transmit the SR message. For example, the network device detects that no available resource can be allocated to the terminal device at this time, but has enough buffer space, and can buffer the SR message transmitted by the terminal device, so as to instruct the terminal device not to transmit the SR message again in the next DRX ON state. The method can also save certain power consumption of the terminal equipment.
For example, as shown in fig. 6, when the first timer is an SR-ProhibitTimer, and in fig. 6, the terminal device starts the SR-ProhibitTimer after sending the SR message, under the condition that the first timer is the SR-ProhibitTimer. And in the running period of the SR-ProhibitTimer, the terminal equipment immediately stops running the SR-ProhibitTimer after receiving the first indication signaling, enters a dormant state, namely, the monitoring of the PDCCH is suspended, so that certain power consumption can be saved. Since the terminal device does not send the SR message in the next DRX ON state, it can be known that the first indication signaling indicates that the terminal device suspends sending the SR message after the next DRX cycle arrives.
For the case that the first timer is the scheduling request judgment timer, the description is omitted here, similarly to the case that the first timer is the SR-prohibit timer.
By the embodiment of the application, the terminal equipment can send the SR message in the current DRX period so as to trigger the starting of the first timer, and the terminal equipment can monitor the PDCCH during the operation of the first timer. The first timer may be an SR-ProhibitTimer, or a scheduling request determination timer. If the terminal device does not monitor the uplink grant in the PDCCH during the operation of the first timer and the second timer is not timed after the operation of the first timer is overtime, the terminal device may send the SR message again after the next DRX cycle is reached. And when the second timer runs, the terminal equipment is in a DRX ON state. In addition, if the terminal device receives the first indication signaling during the operation of the first timer, the terminal device may also stop the operation of the first timer in advance, that is, stop monitoring the PDCCH and/or sending the SR message in advance. By the method, the terminal equipment can send the SR message in one DRX period and start the first timer, and if the uplink authorization in the PDCCH is not monitored under the condition that the first timer runs overtime, the SR message is not sent again in the current DRX period and the PDCCH is not monitored any more, so that the power consumption of the terminal equipment during scheduling can be reduced. In the process of scheduling, if the terminal device receives the first indication signaling, the terminal device may stop scheduling in the current DRX cycle, thereby further reducing power consumption.
