Multi-bit scheduling request

Abstract:

Aspects of the present disclosure provide mechanisms for utilizing a single uplink grant to transmit scheduling requests (SRs) for two or more logical channels. A base station may allocate a separate grant of uplink resources for each SR opportunity (e.g., each logical channel for which a user equipment (UE) may transmit a SR to the base station). When the allocated uplink resources are within the same time period, the UE may select a subset of the SR opportunities for which to transmit a SR and partition the subset into one or more groups of SR opportunities. The UE may then generate one or more SR bits representing the one or more groups of SR opportunities and transmit the one or more SR bits on the single uplink grant.
