The method that provides in order more clearly to set forth above-described embodiment one, in conjunction with foregoing, by following examples two to embodiment four, the method that embodiment one is provided is elaborated, and sees following embodiment two to four for details:

Embodiment two

The present embodiment provides a kind of method of definite Timing Advance, on the basis of the method that above-described embodiment one provides, for convenience of explanation, the present embodiment sends indication information with eNB to UE, and UE determines that according to this indication information random access procedure that eNB triggers is for the TA that upgrades auxiliary residential quarter place TAG or the TAG reprovision is carried out in auxiliary residential quarter is set to example, and the method that the present embodiment is provided is elaborated.Referring to Fig. 2, the method flow that the present embodiment provides is specific as follows:

201:eNB triggers UE and carries out random access procedure after detecting auxiliary cell uplink lock-out or being about to lock-out;

For this step, after eNB detects auxiliary cell uplink lock-out or is about to lock-out, can pass through PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) triggers UE and carry out random access procedure, for example, eNB carries out random access procedure by triggering UE to UE transmission PDCCH Order (order).In addition, can also adopt other triggering modes, the present embodiment does not trigger the mode that UE carries out random access procedure to eNB and limits, and up lock-out or the mode that is about to lock-out limit eNB not to be detected auxiliary residential quarter equally.

202:eNB sends indication information to UE, and this indication information is used to indicate random access procedure to be for the TA that upgrades auxiliary residential quarter place TAG or TAG to be carried out in auxiliary residential quarter reshuffle;

Particularly, in order to make the purpose of the random access procedure that the clear and definite eNB of UE triggers, so that follow-up UE can upgrade the TA of auxiliary residential quarter place TAG or TAG carried out in auxiliary residential quarter reshuffle according to the purpose that triggers random access procedure, eNB can trigger UE carry out random access procedure before, among or afterwards, send indication information to UE, to indicate this random access procedure be for the TA that upgrades auxiliary residential quarter place TAG or TAG is carried out in auxiliary residential quarter reshuffle by this indication information.

For example, in above-mentioned steps 201, if eNB triggers random access procedure by sending PDCCH Order to UE, then can by in this PDCCH Order, adding the mode of this indication information, this indication information be sent to UE.And the form of this indication information both can be character or the field that consults between eNB and the UE, also can be the bit relationships that consults, for example, indicate the random access procedure of triggering as upgrading the TA of auxiliary residential quarter place TAG take 0 of 1bit (bit), indicating the random access procedure of triggering with 1 of 1bit is TAG to be carried out in auxiliary residential quarter reshuffle, certainly, can also adopt the form of other indication informations and the mode that sends indication information, the present embodiment does not limit to the mode of UE transmission indication information and the concrete form of indication information eNB.

203:UE receives TA and the indication information that eNB sends in random access procedure;

For this step, because random access procedure is comparatively ripe prior art, the present embodiment repeats no more this.At random access procedure, eNB can be at PDSCH (Physical Downlink shared channel, Physical Downlink Shared Channel) sends RAR (Random Access Response to UE on the channel, accidental access response) message, this RAR message is by MAC (Medium Access Control, the media access control) layer produces, and it has comprised the TA that UE need to adjust.And indication information is as described in the content in the above-mentioned step 202, eNB both can be carried at it among PDCCH Order, also can adopt other modes to send, UE can obtain TA and indication information by it is resolved after receiving the RAR message that comprises TA and having carried the message of indication information.

204:UE determines that according to the indication information that receives random access procedure that eNB triggers is for the TA that upgrades auxiliary residential quarter place TAG or TAG is carried out in auxiliary residential quarter reshuffle;

Wherein, it is in order to upgrade the TA of auxiliary residential quarter place TAG that this indication information that receives both can have been indicated random access procedure, also can indicate this random access procedure is TAG to be carried out in auxiliary residential quarter reshuffle, no matter which kind of the specific purposes of the indicated triggering random access procedure of this indication information that receives are, can determine that according to the indication information that receives random access procedure that eNB triggers is for the TA that upgrades auxiliary residential quarter place TAG or TAG is carried out in auxiliary residential quarter reshuffle.

The result that the 205:UE basis is determined and the TA that receives upgrade the TA of auxiliary residential quarter place TAG or TAG are carried out in auxiliary residential quarter reshuffle.

Particularly, be in order to upgrade the TA of auxiliary residential quarter place TAG if the result who determines is random access procedure that eNB triggers, then UE TA that eNB is sent is as the TA of auxiliary residential quarter place TAG;

Perhaps, if the result who determines is that the random access procedure that eNB triggers is TAG to be carried out in auxiliary residential quarter reshuffle, then UE stores the TA that eNB sends, follow-up eNB is in order to notify the UE TAG of auxiliary cell re-configuration postpone, eNB also will send reconfiguration message to UE, and the present embodiment does not limit the reconfiguration message that eNB sends, for example, can be RRC (Radio Resource Control, Radio Resource control) message, MAC message or L1 message etc.

After UE received the TAG sign that eNB sends, if the TAG that eNB sends is designated existing TAG sign, and existing TAG sign was identical with the sign of auxiliary residential quarter place TAG, then with the TA that the stores TA as auxiliary residential quarter place TAG; If perhaps the TAG that sends of eNB is designated existing TAG sign, and existing TAG is designated other the existing TAG signs beyond the place TAG of auxiliary residential quarter, then other existing TAG identified corresponding TAG as the TAG at place, auxiliary residential quarter, and the TA of deletion storage; If perhaps the TAG that sends of eNB is designated new TAG sign, then the new TAG that new TAG sign is corresponding is as auxiliary residential quarter place TAG, and with the TA of storage as the new TA of TAG.

The method that the present embodiment provides, after eNB detects auxiliary cell uplink lock-out or is about to lock-out, send TA by triggering random access procedure to UE, make UE determine that random access procedure that eNB triggers is to carry out for the TA that upgrades auxiliary residential quarter place TAG or to auxiliary residential quarter after TAG reshuffles, upgrade the TA of auxiliary residential quarter place TAG or TAG is carried out in auxiliary residential quarter reshuffle according to the result who determines and the TA that receives, thereby when the TA in TAG changes, a kind of mode of effectively determining TA is provided, improves the accuracy of the Timing Advance of determining.
