Combination, although transmission frequency is restricted, but power overhead need not read still than larger
When CRS+PSS/SSS, these power are wasted.In addition, the information exchange of Small cell and terminal
It must be controlled by macro base station, i.e. the wake-up of small cell is terminal notification macro base station, and by macro base station
Wake up Small cell's.For 5G wireless systems, system is probably isolated networking, Bu Huiyi
Rely in previous network, so corresponding wake-up mechanism can not be used.

Individual or multiple AC constitute an access configuration set (ACS).ACS can be sent or TP by macro base station
Part TP in cluster is sent, AC configured informations (such as AC that terminal can be sent by part TP in cluster
Index etc.) currently available AC is determined from the ACS received.
In this example, terminal is received before the first reference signal, can be by receiving other signals such as DRS
Signal, AC configured informations etc. are thick synchronous with system to obtain, and the MSG1's of its up transmission is basic
Time migration, frequency shift (FS) or phase offset are all controlled and adjusted in certain scope, are easy to TP
Receive.The first reference signal that network side equipment is sent can be used for the essence of progress time, frequency or phase
Fine control and tracking.In this example, the first reference signal can be additionally used in RRM (RRM：Radio
Resource Management), RRM measurements such as can be Reference Signal Received Power (RSRP：
Reference Signal Receiving Power) measurement, or Reference Signal Received Quality (RSRQ：
Reference Signal Receiving Quality) measurement etc..First reference signal can be additionally used in channel estimation,

Power, realizes the design principle centered on terminal.
In this example, terminal is carried out after corresponding RRM measurements according to the first reference signal of reception, is led to
The TP that selected TP after measurement result and/or measurement is sent in cluster by upstream message is crossed, such as is sent
Main transmission node (Primary TP) numbering of selection is measured according to RSRP.
In this example, TP can be in defined maximum transmission duration, on reference signal resource periodically
The first reference signal is sent, when receiving the upstream message of terminal feedback or reaching the maximum transmission
It is long.Can also periodically it be sent always after triggering is sent.
Signaling process between this example TP and terminal can be found in shown in Fig. 6, and terminal receives what TP was sent
AC configured informations, or receive AC configured informations and ACS；Terminal determined after currently available AC,
MSG1 is sent in the resource that the AC is indicated, wherein the leading of Stochastic accessing can be carried；TP is received
MSG2 is sent after MSG1, the reference signal resource used in the first reference signal is indicated by MSG2；
Then TP sends the first reference signal on the reference signal resource；Terminal receives the first reference signal
After measure, the TP selected by upstream message to TP feedback measurements or according to measurement result.
Example two
In this example, terminal is only moved in cluster, and down-going synchronous situation can also be kept, terminal base in cluster
Stand or TP between switch (handover) when, it is also possible to need carry out cluster in RRM measurement, now eventually
End can access the AC for obtaining and preserving according to initial synchronisation, initiate access during actively application measurement, hair
Send access request message MSG1.
The signaling process of this example is as shown in fig. 7, compared with example one, terminal need not be received from TP
AC configured informations or ACS, the transmission and processing of other message can be identical with example one, here no longer
Repeat.First reference signal therein can be used for RRM measurements, channel estimation, channel measurement,
Precise synchronization tracks the one or more in being trained with wave beam.
Example three
In this example, the multi-upstream access process of terminal to TP is similar to the traditional of LTE and initial random connect
Enter process, as shown in figure 8, in addition to terminal obtains AC configured informations, ACS, please by access
Ask message MSG1 realize access request it is leading transmission, by access request response message MSG2 realize with
Machine access request is responded, and unlike example one and example two, and TP is not that the is indicated in MSG2
The reference signal resource of one reference signal, but after the upstream message MSG3 of terminal transmission is received, hair
The reference signal resource is just indicated in the contention resolution message MSG4 sent；Afterwards, the first ginseng is retransmited
Examine signal；Terminal is measured after receiving the first reference signal, is fed back by another upstream message to TP
Measurement result or the TP selected according to measurement result.
MSG1-MSG4 defined in the initial random access procedure of MSG1-MSG4 and LTE of this example
Similar, difference is, when TP issues contention resolution message MSG4, also shows or implicitly indicates
First reference signal sends reference signal resource used, and is sending first with reference to believing then to terminal
Number resource.And after terminal receives the first reference signal, then report measurement results or the TP of selection.This
In example, the effect of the first reference signal and the indicating mode of reference signal resource can be with the phases of example one
Together, repeat no more.
