Background technology
Advanced long-term evolution system (LTE-Advanced, Long Term Evolution Advance) be third generation partner program (3GPP, the 3rd Generation Partner Project) tissue is in order to meet (the ITU of International Telecommunications Union, the requirement of International Telecommunication Union), senior international mobile communication (IMT-Advanced, International Mobile Telecommunication-Advanced) and the standard released.LTE-Advanced system is at long evolving system (LTE, Long Term Evolution) an evolution version on basis, it has introduced the primary demand that a lot of new technologies meet IMT-Advanced, and wherein a most important technology is exactly carrier aggregation.
Property in short supply due to current radio spectrum resources, the frequency spectrum resource that each mobile operator of the world has is often more scattered, and IMT-Advanced requires, the index of peak rate is higher (supports 100Mbps under high mobility, under Hypomobility, support 1Gbps), bandwidth with the maximum 20MHz of current LTE standard cannot meet IMT-Advanced requirement, so need to extend to more high bandwidth, such as 40MHz, 60MHz, even higher.One of method that improves bandwidth and peak rate is that frequency domain is expanded, for example, several LTE frequency bands based on 20MHz are carried out to bandwidth expansion by the mode of " carrier aggregation ", the essence of carrier aggregation technology that Here it is.Therefore, LTE-Advanced system also belongs to multicarrier system.
Applied in the LTE-Advanced system of carrier aggregation technology, the carrier wave that participates in polymerization is called as component carrier (Component Carrier), subscriber equipment (User Equipment, referred to as UE) can be received and dispatched transmission with eNB simultaneously on a plurality of component carriers.Component carrier can be used the defined frequency range of LTE, also can use the special newly-increased frequency range into LTE-Advanced.Nervous based on current frequency spectrum resource, can not always have component carrier continuous on frequency domain can distribute to operator and use, so component carrier can be continuous on frequency band, can be also discontinuous.
In carrier aggregation system, for some subscriber equipmenies, can there be a first carrier and one or more the second carrier wave.First carrier is generally main carrier wave, can carrier signaling and data, and the second carrier wave is mainly used in carrying data, also can bearing part signaling.Carrier wave can be divided into up-link carrier (arriving control station communication for subscriber equipment) and descending carrier (arriving communications of user equipment for control station).The wireless service areas of corresponding first carrier is first service district, and the wireless service areas of corresponding the second carrier wave is second service district.In different systems, first carrier, first service district and the second carrier wave, the concept in second service district and title all can have corresponding details definition.
For example, in LTE/LTE-A system, the subscriber equipment that has configured carrier aggregation only has a RRM (RRC, Radio Resource Control) to connect in net.RRM connect set up/re-establish/switch while occurring, provide the service area (Serving Cell) of NAI mobile message and safety input to be called as main plot (Primary Cell, PCell), it is first service district, and according to UE capability, configuration can configure one or more auxiliary community (SCell, Seondary Cell), i.e. second service district.Further, carrier wave corresponding to main plot is exactly main carrier, comprising descending principal component carrier wave (the DL PCC to customer equipment data transmission for control station, Downlink Primary Component Carrier) with the up principal component carrier wave of communicating by letter to control station number for subscriber equipment (UL PCC, Uplink Primary Component Carrier).Similarly, carrier wave corresponding to auxiliary community is exactly auxiliary little carrier wave, wherein, comprise descending auxiliary component carrier (the DL SCC to customer equipment data transmission for control station, Downlink Secondary Component Carrier) with for subscriber equipment to the up auxiliary component carrier (UL SCC, Uplink Secondary Component Carrier) of control station data communication.
In LTE system, in order to realize and to keep the uplink synchronous between subscriber equipment and base station, base station is according to the propagation delay time transmitting time lead (TA between base station and each subscriber equipment, Timing Advance) give each subscriber equipment, the opportunity that the Timing Advance that subscriber equipment sends according to base station shifts to an earlier date or postpones uplink separately, thereby making up UE in user, to the propagation delay time of base station, makes the upward signal of different user devices all within the receive window of base station, arrive base station.
In LTE system, in order to obtain and to keep the uplink synchronous between UE and base station, base station is that UE has configured a upstream synchronous timing device (TAT, Time Alignment Timer), if UE can receive the Timing Advance that base station sends to UE before TAT is overtime, think and keep uplink synchronous between this UE and this base station, otherwise TAT is overtime, UE thinks and loses uplink synchronous.At not synchronous regime or desynchronizing state, UE by random access procedure, obtain and base station between uplink synchronous, UE receives the accidental access response (RAR that base station sends, Random Access Response) after, start timer TAT, and the Timing Advance carrying according to base station shifts to an earlier date or postpones the opportunity of uplink in accidental access response.After the uplink synchronous of UE acquisition and base station, at TAT run duration, if receive the TA order (TA command) that base station sends to UE, restart TAT, and using the Timing Advance that carries in TA order in advance or postpone the uplink time, UE thinks own and continues and base station maintenance uplink synchronous, if UE does not receive TA order at TAT run duration, be that TAT is when overtime, UE thinks own and has lost uplink synchronous with base station, delete dynamic assignment to all up-downgoing resources of this UE, empty all up mixed self-adapting retransmission buffers to be sent (HARQ buffer) data, notice Radio Resource is controlled (RRC, Radio Resource Control) sublayer discharges static state/semi-static ascending physical signal resource of distributing to this UE, if after this there is upstream data need to send or have downlink data to need to receive, UE needs first to carry out to access to regain uplink synchronous at random.
Introduce after carrier aggregation, subscriber equipment may be simultaneously operated on a plurality of component carriers, and these component carriers can be continuous on frequency band, can be also discontinuous; Can be in identical frequency band, can also be to come from different frequency bands.For the discontinuous situation of component carrier, or component carrier comes from the situation of different frequency bands, and because each component carrier has different transmission characteristics, the Timing Advance on each component carrier may be different; Even each component carrier belongs to identical frequency band and on frequency band continuously, if each component carrier is derived from different Remote Radio Unit (RRU, Remote Radio Unit), or cover in order to increase community, each component carrier is processed via different repeater (repeater) respectively, and the Timing Advance on each component carrier also may be different.In LTE system, it (is a carrier wave for TDD mode that UE is only operated on a carrier wave, for mode of frequency division duplexing, comprise up, descending a pair of carrier wave, for convenience of description, here be called for short a carrier wave), only need to safeguard the uplink synchronous of a up link, and in carrier aggregation, UE may be simultaneously operated on a plurality of component carriers, and the TA of these component carriers is likely different.This scene is referred to as many TA (MTA, Multiple TA).Use same TA and have all communities of same downlink time reference to form a TA group (TA GROUP).
As previously mentioned, in single TA scene, UE by random access procedure, obtain and base station between uplink synchronous.Random access procedure can be by the media access control layer (MAC of Physical Downlink Control Channel signaling (PDCCH order) or UE, Medium Access Control) initiate, alternatively, PDCCH order or Radio Resource are controlled (RRC, Radio Resource Control) signaling can be distributed special random access preamble (Random Access Preamble) for UE, and random access procedure is the non-mode based on competition; Otherwise UE need to select random access guiding, random access procedure is the mode based on competition.UE selection random access resource comprises the time-frequency domain resources of selection random access guiding and Physical Random Access Channel (PRACH, Physical Random Access Channel) etc.
Fig. 1 is that as shown in Figure 1, the random access procedure based on competition (Contention based) comprises the following steps based on competition random access procedure flow chart:
Step 101, UE sends random access guiding (Random Access Preamble) up by Random Access Channel (RACH, Random Access CHannel).
Step 102, media access control layer (the MAC of base station (eNB), Medium Access Control) generate accidental access response (RAR, RandomAccess Response) message, and send to UE at DSCH Downlink Shared Channel (DL-SCH, Downlink-Shared Channel); In this RAR message, at least comprise random access guiding sign (RAPID, Random Access Preamble IDentifier), time adjustment information (TA, Time Alignment), initial uplink mandate (UL Grant, Uplink Grant) and interim community-Radio Network Temporary Identifier (Temporary C-RNTI); This message is passed through at Physical Downlink Control Channel (PDCCH, Physical Downlink Control CHannel) the random access-Radio Network Temporary Identifier on (RA-RNTI, Random Access-Radio Network Temporary Identifier) is indicated; UE need to receive this accidental access response message in a predetermined receive window.
Step 103, UE is in the upper first transmission being scheduled (Scheduled Transmission) message that sends of up shared transmission channel (UL-SCH, Uplink-Shared Channel); The content of this message at least comprises community-Radio Network Temporary Identifier (C-RNTI, Cell-Radio Network Temporary Identifier), media access control unit (MAC Control Element) or comprises that competition solves the public control logic channel Service Data Unit (CCCH SDU) of sign (Contention Resolution Identity); Mixed automatic retransfer request (HARQ, Hybrid Automatic Retransmission re Quest) is supported in the transmission of this message.
Step 104, base station sends competition and solves message (Contention Resolution) on DL-SCH; This message is indicated by the C-RNTI on PDCCH or interim C-RNTI, can comprise that competition solves sign; HARQ is supported in the transmission of this message.
Fig. 2 is based on non-competing random access procedure flow chart, as shown in Figure 2, for non-competing random access procedure, does not compete solution process, specifically comprises the following steps:
Step 201, UE sends random access guiding up by Random Access Channel.
Step 202, the media access control layer of base station generates accidental access response message, and sends to UE at DSCH Downlink Shared Channel.
In conventional art, random access procedure can only carry out in main plot, can not carry out Fu community.
In prior art, under MTA scene, for obtaining the upper TA of SCell, UE must send RA preamble on Scell, and then UE receives corresponding RAR message on PCell.Conventional art definition RA-RNTI and C-RNTI/ semi-persistent scheduling Radio Network Temporary Identifier (SPS-RNTI in same subframe, while Semi Persistent Scheduling-Radio Network Temporary Identifier) being used, UE does not need to decode, and those make the indicated data (transmitting on corresponding PDSCH) of PDCCH of CRC (CRC, Cyclic Redundancy Check) of C-RNTI/SPS-RNTI scrambling.This is defined on conventional art is reasonably, and the RAR that UE receives RA-RNTI scrambling on PCell just often means that the radio link quality of UE and system is bad, therefore without the need for other transmission and receiving course.Therefore, the information of the transmission/reception RA-RNTI scrambling simultaneously of different carrier waves and C-RNTI/SPS-RNTI scrambling.In multicarrier system, owing to having introduced MTA scene, if UE on PCELL, receive the RAR of RA-RNTI scrambling corresponding be the random access procedure of SCell, now just no longer relevant to the radio link quality of system with UE, now with regard to the information of while transmission/reception RA-RNTI scrambling and C-RNTI/SPS-RNTI scrambling likely.
For the problems referred to above, not yet related art scheme can be for reference at present.
