If there is a cell load is high, but the number of users threshold is not reached MOD CELLMLB and cannot be balanced situation, you can reduce this threshold.

SRS switch supports only 400 users, which is higher than this threshold, still employ DMRS scheduling; Since applies to: based on the load status, SRS adaptive to configuration or to SRS: in the light load, number of users, relatively few scenarios, using DMRS scheduling, reduce the overhead of SRS symbol introduction; Number of subscribers in heavy traffic, cell than many and initiate base station in scenarios the PUSCH interrogation will not to any data, start HARQ retransmission uplink PUSCH, waste resources and lead to bit error rate significantly up into the air. Open after the optimization, items, the base station uplink DTX are detected will be delivered again after the uplink scheduling authorization and no longer launches HARQ retransmission, if detected after the second release the authorization still DTX, the system will stop the SR scheduling. So, we can DTX, is no longer the follow-up of SR rescheduling; If the SR scheduling detected as NACK, and reaches HARQ maximum retransmission times still are not transferred successfully, in the DRX open cases, SR twice in the back of the scheduling rescheduling need in DRX can perform only during the long period mode 2 results vary with assignment starting position, that is, from the highfrequency location allocation begins or FS_INRANDOM_ADA start from low-frequency location PTIVE distribution, to a certain extent, to resource allocation to be different from the objective of neighboring cell, reduce
