Abstract
Various schemes are provided to improve SR resource utilization by adapting SR resource allocation to traffic pattern. In a first Scheme, SR resource allocation is configured more accurately. In one example, UE provides assistant information for eNB to determine or adjust SR configuration based on the received assistant information. In a second Scheme, multiple SR periods are configured and adapted to traffic pattern. In one example, eNB configures a set of SR resources with multiple SR periods, and UE applies different SR periods based on predefined events. Unused SR resources could be recycled by eNB for PUSCH data transmission. In a third Scheme, multiple SR allocations are configured and adapted to concerned applications. In one example, eNB configures multiple sets of SR resources adapted to predefined applications, and UE applies SR configurations based on corresponding applications. The additional SR configurations could be activated and/or deactivated.
