摘要： Methods and apparatuses are presented for managing a multi-subscriber identity module (SIM) user equipment (UE) such that data throughput may be improved in a dual-SIM, dual active (DSDA) scenario. For example, a method is presented that includes acquiring first timing information of a first subscription and second timing information of a second subscription. Additionally, the example method may include detecting a first conflict between communications of the first subscription and the second subscription in a time slot of a first time interval. Moreover, the example method may include estimating one or more additional conflicts in one or more subsequent time intervals based on timing of the time slot, the first timing information, and the second timing information. Further, the example method may include respectively adjusting one or more transmit block sizes (TBS) for each of the one or more subsequent time intervals.
