Further, the transmitting element 104, is additionally operable to when it is upstream data bag that the determining unit 102, which determines the upstream data to be sent, and the BSR message and the upstream data bag are sent to the base station by first ascending resource.
The embodiments of the invention provide a kind of user equipment (UE), UE is after the first ascending resource of base station transmission is received, determine whether the first ascending resource is more than UE and sends ascending resource required during BSR message, if it is determined that the first ascending resource, which is more than UE, sends ascending resource required during BSR message, then UE determines the second ascending resource according to the first ascending resource, and when it is determined that receiving wrong data bag, determine upstream data to be sent whether be state report data, if it is determined that when upstream data to be sent is the data of state report, then UE it is determined that the second ascending resource on the data of the state report are encapsulated as status report data bag, and determine whether packaged status report data bag is more than the first preset value, when it is determined that packaged status report data bag is not more than the first preset value, UE sends BSR message by the first ascending resource to base station, without sending packaged status report data bag, now, because BSR carries the size of effective upstream data request, then so that base station is after the BSR message of UE transmissions is received, enough ascending resources are sent to UE according to the size that the effective upstream data carried in BSR message is asked, so as to which effective state report is sent to base station by UE according to this ascending resource.Or, BSR message and packaged status report data bag are sent to base station by the first ascending resource, and UE does not start the timer relevant with status report, now, because the timer relevant with status report is not actuated, then UE can also status report, that is BSR carries the size of effective upstream data request, then so that base station is after the BSR message of UE transmissions is received, enough ascending resources are sent to UE according to the size that the effective upstream data carried in BSR message is asked, the final UE that realizes sends effective state report, so as to ensure the correct transmission of upstream data request, so as to UE and base station proper communication.
The embodiments of the invention provide a kind of method that data are sent, as shown in Fig. 2 including：201st, UE receives the first information that base station is sent.
Wherein, the first information is used to indicate that the base station is the first ascending resource that the UE is distributed.First ascending resource is that the UE is distributed in the base station, the resource for sending BSR message.The BSR message is used to indicate the big of upstream data to be sent It is small.
Specifically, when UE sends BSR message to obtain the ascending resource used when UE sends upstream data to base station, UE needs first to send SR (Scheduling Request, uplink scheduling request to base station）Message, the ascending resource of BSR message is sent to cause base station to be distributed according to the SR message received to UE, i.e. the first information is distributed in base station according to the SR message received to UE, and send the first information for distributing to UE to UE, now, UE receives the first information that base station is sent, i.e. UE receives the first ascending resource for being used to send BSR message that UE is distributed in base station.
202nd, the UE determines whether first ascending resource meets the first preparatory condition.Wherein, first preparatory condition refers to that the ascending resource of the BSR message of base station distribution is more than the UE and sends ascending resource required during the BSR message.
Specifically, the UE determines to send ascending resource required during the BSR message；And determine whether first ascending resource is more than the ascending resource sent needed for the BSR message；If the UE determines the ascending resource that first ascending resource is more than needed for the UE transmissions BSR message, the UE determines that first ascending resource meets first preparatory condition.
That is, UE determines to send first ascending resource required during BSR message, then the first ascending resource base station received distributed is compared with sending ascending resource required during BSR message, if UE determines that the first ascending resource of the base station distribution received is more than ascending resource required when sending BSR message, then UE determines that the first ascending resource of the base station distribution received meets the first preparatory condition, if UE determines that the first ascending resource of the base station received distribution is not more than ascending resource required when sending BSR message, then UE determines that the first ascending resource of the base station received distribution is unsatisfactory for the first preparatory condition.
If the 203, the UE determines that first ascending resource meets the first preparatory condition, the UE determines the second ascending resource according to first ascending resource.
Wherein, second ascending resource refers in first ascending resource, removes the remaining ascending resource that the UE sends ascending resource required during the BSR message.
Specifically, the ascending resource UE required when the first ascending resource of the UE base station distribution for determining to receive is more than transmission BSR message, that is, determine on the base station received is distributed first When row resource meets the first preparatory condition, in the first ascending resource that UE is distributed in base station, ascending resource required when sending B S R message is removed, remaining ascending resource is defined as the second ascending resource.
2 04, when it is determined that receiving wrong data bag, the UE determine upstream data to be sent whether be state report data.
Wherein, the state report is reported for RL C-states.
Specifically, UE is when it is determined that receive wrong data bag, need to send the state report for carrying feedback error packet information to base station, control message, to cause base station to receive after the state report that U E are sent, the wrong data package informatin in this state report is parsed, and packet is re-transmitted to by UE according to this wrong data package informatin.Because UE is also possible to send upstream data bag to base station, that is data message, so UE is it needs to be determined that whether the upstream data sent only has state report, if now UE does not send upstream data bag and only status report to base station, U E determine the data that upstream data to be sent is state report.If now UE sends upstream data bag and state report to base station, UE determines that upstream data to be sent is not the data of state report.
If 205, the UE determines that the upstream data to be sent is the data of the state report, the data of the state report are encapsulated as status report data bag by the UE according to second ascending resource.
Specifically, when it is the data of state report that UE, which determines upstream data to be sent, UE it is determined that the second ascending resource on, the data of state report to be sent are encapsulated as status report data bag according to the encapsulation format of control message.
206, the UE determines whether the status report data bag is more than the first preset value.Wherein, first preset value is pre-set, and is packaged into the minimum byte number of status report data bag.
Specifically, after state report to be sent is encapsulated as status report data bag by UE according to the second ascending resource of determination according to the encapsulation format of control message, UE needs to judge whether packaged status report data bag is the minimum byte number for being packaged into status report data bag, that is the first two byte of the data of state report, if UE determines that packaged status report data bag is more than the minimum byte number for being packaged into status report data bag, illustrate packaged state Data reporting bag includes the information of feedback error packet information, if UE determines that packaged status report data bag is the minimum byte number for being packaged into status report data bag, illustrate that packaged status report data bag does not include the information for having feedback error packet information.
It should be noted that, UE is in the data reported according to the second ascending resource encapsulation state of determination, need to judge the second ascending resource for determining whether can encapsulation state data reporting bag the first two byte data message, if UE determine the second ascending resource at least can encapsulation state data reporting bag the first two byte data message, the data of state report are then encapsulated as status report data bag, if UE determines that the second ascending resource is unable to the data message of the first two byte of encapsulation state data reporting bag, the data of this state report are not encapsulated.
207th, when determining that the status report data bag is not more than first preset value, the UE sends the BSR message by first ascending resource to the base station, and the status report data bag is not sent.
Specifically, determine that packaged status report data bag is the minimum byte number that is packaged into status report data bag in UE, when i.e. packaged status report data bag does not include the information for having feedback error packet information, now, ascending resources of the UE needed for by sending the BSR message sends BSR message, without sending packaged status report data bag by the second ascending resource.Now, because BSR carries the size of effective upstream data request, then so that base station is after the BSR message of UE transmissions is received, the size asked according to the effective upstream data carried in BSR message distributes the ascending resource of enough transmission upstream datas to UE, and send this ascending resource to UE, then this ascending resource that UE can be distributed according to base station sends effective state report.
Or, the UE sends the BSR message and the status report data bag by first ascending resource to the base station, and the UE does not start the timer relevant with sending the state report.
Wherein, the timer relevant with sending the state report is used to set UE for the first time to the time interval of second of the time to base station status report of the time of base station status report and UE.
Specifically, determining that packaged status report data bag is not more than in U E is packaged into the minimum byte number of status report data bag, i.e., packaged status report data bag, which does not include, anti- When presenting the information of wrong data package informatin, then ascending resources of the UE needed for by sending the BSR message sends BSR message, packaged status report data bag is sent by the second ascending resource, now, UE does not start the timer relevant with sending the state report, then UE can also be to base station status report, the size for then illustrating the upstream data carried in BSR message request is effective, then so that base station is after the BSR message of UE transmissions is received, parse this BSR message, so as to obtain the size of the upstream data carried in BSR message request, and the size asked according to upstream data distributes the ascending resource of enough transmission upstream datas to UE, and send this ascending resource to UE, this ascending resource that then UE can be distributed according to base station sends effective state report.
