Description
Technical field
The present invention relates to the communication technology, be specifically related to a kind of scheduling request sending method and subscriber equipment.
Background technology
LTE (Long Term Evolution) system is a communication system based on scheduling, if promptly there are data to need to send in the transmission buffer memory of UE, UE needs to send a BSR (buffer status report) to eNB earlier so, and telling needs the data message that sends in the current transmission buffer memory of eNB UE.How many eNB comes for UE distributes corresponding UL-SCH (Uplink Shared Channel) resource according to the data that UE will send after receiving the BSR that UE sends, and notice UE sends data on the UL-SCH resource of distributing.UE sends BSR to eNB also needs to use the UL-SCH resource, if there is BSR to report, but there is not the Uplink Shared Channel resource this moment, so just need utilize PUCCH (Physical Uplink Control Channel) specific schedule request resource to send SR (dispatch request) or initiate to insert at random and carry out SR, request eNB distributes the Uplink Shared Channel resource for the BSR that needs to send.Detailed process is as follows:
1) UE has upstream data to need to send, but does not send the Uplink Shared Channel resource of data in the up link, triggers BSR so and reports;
2) if there is not the Uplink Shared Channel resource to transmit BSR, then triggers SR and report.
After triggering SR, the mode that sends SR has two kinds, that is: send SR (being D-SR) and carry out SR (being RA-SR) by random access procedure by the specific schedule request resource.Wherein, the D-SR resource is by RRC (Radio Resource control) configuration, and by the PUCCH carrying, the D-SR resource is used for sending D-SR; RA-SR utilizes random access procedure to carry out SR.As long as the D-SR resource is arranged, then do not carry out RA-SR.UE receive eNB be its distribution be used to send the UL-SCH resource of data before, can repeat to send SR on the D-SR resource can sending.
In existing standard, the detailed process that SR sends is as follows:
When certain TTI has data to send but do not have UL-SCH (Uplink Shared Channel) resource, can there be following two kinds of situations:
(1) do not send SR if in any TTI (Transmission Time Interval), all dispose effective PUCCH (Physical Uplink Control Channel) resource, then initiate random access procedure and discharge the SR of all states that are untreated;
(2), and do not measure at this TTI if in certain TTI, exist effective PUCCH resource to send SR, then:
If the count value of SR counter is less than the maximum number of times of transmission of SR, the count value of SR calculator adds 1, and the indication physical layer sends a SR on PUCCH; Otherwise notice RRC discharges PUCCH/SRS (Sounding Reference Symbols, detection reference signal) resource, initiates a random access procedure and discharges the SR of all states that are untreated.
If in certain TTI, obtained to be used for the UL-SCH resource of new transmission, then discharge the SR of all states that are untreated.
In existing standard, need wait until that obtaining the specific schedule request resource judges just when (being used to send the PUCCH resource of SR) whether the transmission of SR reaches maximum number of times of transmission, even therefore the transmission of SR has reached maximum number of times of transmission, also need just can initiate random access procedure when obtain the specific schedule request resource next time by the time.If obtain the interval of specific schedule request resource to next time long, will postpone so to insert at random, cause unnecessary dispatch request to postpone.If obtain the interval of specific schedule request resource to next time too short, also do not arrive UE although may occur eNB so to the message that UE has distributed resource to carry Resources allocation, initiate to insert at random the waste that will cause the UL-SCH resource this moment.
