Optionally, above-mentioned first downstream message can be to include following at least one：RRC signaling, RLC state reports, the descending descending MAC CE of RLC AMD PDLL for being provided with poll, uplink scheduling signaling（Information is distributed containing ascending resource）, for upstream data hybrid automatic repeat-request HARQ ACK/NACK.For example, second base station needs the second base station in descending transmission RLC state reports for the up RLC PDU that UE is sent, so that UE decides whether to retransmit up RLC PDU to the second base station according to RLC state reports, and downlink transfer can only be sent to UE by first base station, therefore, the second base station needs RLC state reports being transmitted to first base station by back haul link.

Specifically, descending MAC CE can include any one or more following combination：Timing advance order（TA command), discontinuous receive order (DRX command), activation/deactivation MAC CE, UE and strive solution mark (UE contention resolution identity) etc. unexpectedly, UE strives unexpectedly solves mark striving unexpectedly in solution message i.e. message 4 (msg4) included in random access procedure, subsequent embodiment has a detailed description for message 4, and here is omitted.

Under a kind of implement scene, the Timing Advance that the second base station can determine the Timing Advance sent according to user equipment（Timing advance, TA), first base station is sent to by back haul link, then user equipment is sent on the downlink resource of first community by first base station.

Under another implement scene, DRX command, activation/deactivation MAC CE, striving unexpectedly for user equipment solve the descending MAC CE such as mark, first base station can be sent to by the second base station, then be sent to user equipment on the downlink resource of first community by first base station.

Under another implement scene, the second base station needs to send uplink scheduling signaling to user equipment, for example：Uplink authorization（UL grant), then uplink scheduling signaling by back haul link can be sent to first base station by the second base station, then uplink scheduling signaling is sent into user equipment on the downlink resource of first community by first base station.

Under another implement scene, the second base station needs to send the down mixing self-retransmission request for upstream data sent to the second base station for user equipment to user equipment（Hybrid automatic repeat-request, HARQ) the ACK/NACK of feedback, then descending HARQ feeding back ACKs/NACK can be sent to first base station by the second base station, and user equipment is sent on the downlink resource of first community by first base station.

Under another implement scene, the second base station needs concurrently to serve row RLC status report by the RLC AMD PDU for setting poll bit (poll) to trigger user equipment reception first base station, then optionally, Second base station can generate descending RLC AMD PDU and set Poll, be sent to first base station by back haul link, and be sent to user equipment on the downlink resource of first community by first base station.Either, the second base station can notify first base station to generate descending RLC AMD PDU and set Poll by back haul link, then the RLC AMD PDU for being provided with Poll are sent into user equipment on the downlink resource of first community by first base station.Similar, the second base station is directed to the PDCP status report that up PDCP PDU reception conditions are generated, and first base station can be sent to by back haul link, then be sent to user equipment on the downlink resource of first community by first base station.

Under another implement scene, the descending RLC state reports that the second base station is generated for up RLC AM PDU reception conditions can be sent to first base station, user equipment is sent on the downlink resource of first community by first base station.When under implement scene of the first base station as anchor point, all upstream datas that second base station is received can be sent to first base station by the second base station, and the RLC status report of generation are sent into user equipment on the downlink resource of first community by first base station.Present invention also offers another embodiment of uplink and downlink communication method, as shown in Figure 7, the embodiment is to specific descriptions of the above method embodiment based on different scenes, i.e., to send a kind of embodiment of downstream message to user equipment there is provided the second base station.

Back haul link between first base station and the second base station is undesirable.Under the implement scene, the downstream message that the second base station is sent can not be sent to first base station by back haul link in time.Therefore, under this implement scene, the second base station can be on PDCCH/ E-PDCCH, PHICH/E-PHICH of second community to user equipment the second downstream message of transmission.I.e., user equipment can also receive the downstream message of the second base station transmission in addition to it can send upstream data to the second base station on the ascending resource of the second community of the second base station in PDCCH/ E-PDCCH, PHICH/E-PHICH resources of second community.Wherein, above-mentioned second downstream message can include it is following any one or more：Uplink scheduling signaling, for upstream data hybrid automatic repeat-request HARQ confirmation message ACK/ refuse informations NACK.For example, the downstream message that the second base station is sent to user equipment on the PDCCH/ E-PDCCH of second community has uplink scheduling signaling（Assignment messages containing ascending resource）, the downstream message that is sent on the PHICH/E-PHICH of second community user equipment there is the hybrid automatic repeat-request for upstream data to confirm ACK/ refusal NACK message., it is necessary to illustrate, when first base station is in first community on the basis of embodiment illustrated in fig. 7 On downlink resource downlink data is sent to user equipment, second base station sends downstream message while when carrying out on the downlink resource of second community to user equipment, in order to reduce the interference for the downstream message that first community is sent to second community, second base station can second community E-PDCCH, or on E-PHICH to user equipment send downstream message.Further, the E-PDCCH/E-PHICH and the E-PDCCH/E-PHICH that second community sends downstream message that first community can also be sent to downlink data are configured to by different Physical Resource Block PRB carryings.Optionally, in order to reduce influence of the undesirable back haul link to HARQ feedback time delay, HARQ Loop Round Trip Times can also be reset（), RTT for example：16 or 32 HARQ processes can be used, so that the 8ms HARQ RTT of existing 8 HARQ processes are changed into 16ms or 32ms.On the basis of Fig. 1-embodiment illustrated in fig. 7, for first community and the user equipment at second community edge, it carries out downlink communication on the downlink resource of first community with first base station, and uplink communication is carried out with the second base station on the ascending resource of second community.The DRB of user equipment can be respectively by first base station and the second base station with carrying on core net SGW S1-U interface with S1（S1 bearer) set up mapping relations, the RAB E-RAB of evolution is the carrying between UE and SGW, including two sections of S1 bearer between the Data Radio Bearer DRB and eNB and SGW between UE and eNB, DRB and S1 bearer --- correspondence, so as to establish the data link between UE and SGW, as shown in Figure 8.The process for setting up mapping is briefly described below：MME and eNB set up E-RAB when setting up S1 interfaces, include E-RAB identification informations；It is DRB distribution DRB marks, so as to set up mapping relations between DRB and S1 bearer comprising E-RAB marks in increase DRB information when eNB is UE allocation radio resources.Or, agency can also be used as by one in first base station and the second base station, with setting up mapping relations with S1 bearer on core net SGW S1-U interface, first base station sets up above-mentioned mapping relations with the second base station by interacting E-RAB marks and DRB identification informations, as shown in Figure 9.

On the basis of above-described embodiment, for the discontinuous reception of user equipment, when user equipment receives the downlink resource distribution from first base station or the second base station（DL assignment) or the message such as uplink authorization (UL grant) when being designated as newly transmitting (new transmission), user equipment can start or restart non-active timer（inactivity timer ).If first base station and the second base station downlink transfer respectively by respective PDCCH scheduling user's sets or uplink, when user equipment starts or restarted non-active timer（Inactivity timer) when, in the first community of first base station and second The second community of base station can also start corresponding non-active timer（Inactivity timer), to keep synchronous with the DRX of user equipment operations, so as to which network node knows when user equipment is active (active time), and user equipment just monitors PDCCH only in active state.Therefore, when first base station or second base station initiated or when restarting Inactivity timer, another network node also should correspondingly start or restart Inactivity timer.Therefore, when a network node in first base station and the second base station notifies another network node by back haul link, need to notify the absolute time that Inactivity timer timers start, otherwise because delay can cause DRX operations can not reach synchronization between two network nodes.For HARQ Loop Round Trip Time timers（HARQ RTT Timer), HARQ retransmission timers（Drx-inactivitytimer), short cycle timer（Drx short cycletimer) startup also handled in the same way.Due to duration timer（On durationtimer) Startup time be fixed, it is only necessary to when DRX is configured by DRX start offset（Drx start offset) and on DurationTimer length configuration information between two network nodes share, a network node in first base station and the second base station notifies another network node when for user device configuration DRX, and the length configuration information of other each DRX associated timers is also required to share between two network nodes.On the basis of Fig. 1-embodiment illustrated in fig. 9, due to user equipment it is descending on the downlink resource of first community with first base station carry out downlink communication, on the ascending resource of second community uplink communication is carried out with the second base station, therefore, when user equipment it is up lose synchronization after, need to perform random access procedure, obtain the uplink synchronous with second community.

The invention provides the one embodiment of user equipment based on the random access procedure striven unexpectedly, it can include：

Second base station receives the random access guiding that user equipment is sent in second community；

Or, above-mentioned Stochastic accessing can include： Second base station receives the random access guiding that user equipment is sent in second community；

Second base station will be sent to first base station for the information for generating accidental access response message；Second base station receives the message that there is user equipment to strive solution mark unexpectedly that user equipment is sent in second community；

Second base station will be sent to first base station for generating the information for striving solution message unexpectedly.

As shown in Figure 10, this method is specifically included：

51001st, user equipment selects random access guiding in second community（), preamble and by Physical Random Access Channel (physical random access channel, PRACH) selected preamble is sent.

It should be noted that the present embodiment is based on the Stochastic accessing implement scene striven unexpectedly, under the implement scene, then S1001 is directly performed.And it is directed to the embodiment of the non-Stochastic accessing striven unexpectedly, then user equipment is before random access guiding is sent, second base station is that user equipment distributes random access guiding, and the random access guiding is sent into first base station, and user equipment is sent to by first base station.User equipment is received after random access guiding, then performs S1001.Or, can also be that user equipment distributes random access guiding by first base station, and random access guiding is sent to user equipment.

51002nd, the second base station detects preamble in second community, calculate Stochastic accessing-Radio Network Temporary Identifier (random access-radio network temporary identifier, RA-RNTI), up timing advance value is calculated, Temporary Cell-Radio Network Temporary Identifier is distributed（Temporary C-RNTI) and uplink authorization (UL grant), generate in accidental access response message (ramdom access response, RAR), the RAR and carry preamble.

51003rd, RA-RNTI and RAR are sent to first base station by the second base station by back haul link.

51004th, the descending assignment signalling that first base station is scrambled in the PDCCH of first community by RA-RNTI（DL assignment) downlink resource for receiving RAR is distributed for user equipment.

51005th, first base station sends RAR on the downlink resource of first community to user equipment.

It should be noted that, for another feasible embodiment of S1002 and S1003 steps, second base station can not also directly generate RAR in second community, and will be sent to first base station for generating RAR information, and RAR is generated according to above- mentioned information in first community by first base station.

Wherein, the combination of one or more of is included for generating RAR information：PRACH positional information or RA-RNTI, it is necessary at the time of first community sends RAR and/or uplink authorization entry-into-force time, the Temporary C-RNTI, preamble of distribution etc.. RAR by a message can be sent to user equipment by first base station, and different message can be used to be sent to user equipment.It can illustrate that RAR is generated by first base station or generated by the second base station by increasing configured information in the message.For example：The position of a reservation bit in existing MAC RAR " R " can be used to put " 0 " or " 1 " and represent that the RAR is generated by first base station or generated by the second base station.

S1006, user equipment receive RAR, judge that the RAR is the preamble that itself sends according to RA-RNTI and preamble.

Optionally, the RAR that user equipment is sent in the second community that the first community of first base station receives the second base station by the first community of first base station, can use and different with first community strive solution timer length unexpectedly.In first community user equipment can be allocated to by RRC signaling in advance by first base station.

Optionally, can be with according to whether receiving the accidental access response message in the reception length of window of setting, it is determined whether be successfully accessed the second community in S1001 after user equipment transmission random access guiding.That is, after user equipment sends random access guiding, the accidental access response message for waiting the second community of the second base station to be returned by the first community of first base station, the time of wait is determined by the length of reception window.For example：User equipment sends the 2nd later millisecond of random access guiding and started waiting for, then length of window can be 8ms or 10ms, if not receiving accidental access response message, random access failure.User equipment can according to the actual requirements, and initial time and length of window parameter to accidental access response window are modified.

It should be noted that, under the implement scene that back haul link has delay, the message required time that the second community of second base station is sent by the first community of first base station to user equipment is longer, can exceed that the preset time waited for the arrival of news that user equipment is set.Wherein, user equipment the 3rd subframe after second community sends random access guiding starts waiting for RAR time, window parameter (ra-response window size) is received by the RRC of the first base station RAR configured and determines that the parameter value can select 2 subframes to 10 subframes（The time span of 1 subframe is 1 ms).The larger ra-response window size of increase configuration, example mouthful are needed for the RAR times that user equipment waits the second community from the second base station to be sent by the first community of first base station：Value more than 10ms can be set, or use longer RAR window start times, for example：User equipment can start RAR in the 10th subframe after the second community of the second base station sends random access guiding and receive window.

S1007, user equipment are sent to the second community of the second base station strives the message for solving mark, i.e. message 3 (msg3) with UE unexpectedly.

Wherein, UE strives solution and is designated C-RNTI unexpectedly, can for first base station distribute C-RNTI or The C-RNTI of the base station of person second distribution, UE can also use same C-RNTL in first base station and the second base station
