example 1
[0097] In this example, the DRX cycle is configured for the service performed by the UE in an LTE cell, and the DRX cycle is set to 40ms, the on duration is 10ms, the CQI reporting cycle is 40ms, the CQI subframe offset is 5, and the RI cycle is 40ms , the RI subframe offset is 6, the SRS period is 20ms, and the SRS subframe offset is 1;
[0098] Configuring the starting point of the DRX cycle according to the technical solution of the embodiment of the present invention includes the following processing:
[0099] Step 1, randomly generate an N between 0 and 39, N=10, M=N;
[0100] Step 2, determine whether the CQI has the opportunity to transmit within the on duration time:
[0101] Step 21, calculate DRX cycle , CQI sending period, and the least common multiple of 10: 40;
[0102] Step 22, assigning n=0, that is, starting from the first cycle of DRX, the starting point is that SFN (system frame number) is equal to 0;
[0103] Step 23, calculate Y CQI1 =ceil((10+0+40*0-5...
example 2
[0112] In this example, due to service changes, the DRX cycle is reconfigured for UEs in an LTE cell. The DRX cycle is set to 80ms, the on duration is 10ms, the CQI reporting cycle is 40ms, the CQI subframe offset is 5, and the RI cycle is 80ms, the RI subframe offset is 5, the SRS period is 20ms, and the SRS subframe offset is 1;
[0113] Configuring the starting point of the DRX cycle according to the technical solution of the embodiment of the present invention includes the following processing:
[0114] Step 1, randomly generate an N between 0 and 79, N=50, M=N;
[0115] Step 2, determine whether the CQI has the opportunity to transmit within the on duration time:
[0116] Step 21, calculate DRX cycle , CQI sending period, and the least common multiple of 10: 80;
[0117] Step 22, assigning n=0, that is, starting from the first cycle of the DRX cycle, the starting point is that SFN (system frame number) is equal to 0;
[0118] Step 23, calculate Y CQI1 =ceil((50+0+80*...
example 3
[0127] When the CQI, RI, SRS, and DRX cycles of the UE have configurations that are not integer multiples of 10, the method in the technical solution has more advantages. In this example, since the UE in a certain LTE cell performs DRX configuration, and the CQI, SRS, and RI parameters are modified due to some reasons, it is necessary to re-evaluate whether the DRX cycle start point is set properly.
[0128] Set the DRX period to 40ms, the on duration to 10ms, the CQI reporting period to 40ms, the CQI subframe offset to 5, the RI period to 40ms, the RI subframe offset to 6, the SRS period to 20ms, and the SRS subframe offset to 1 ;
[0129] Due to system performance requirements, the CQI period is modified to 20ms, the CQI subframe offset is 5, the RI period is 40ms, the RI subframe offset is 6, the SRS period is 20ms, and the SRS subframe offset is 1;
[0130] Configuring the starting point of the DRX cycle according to the technical solution of the embodiment of the present...
