BUFFER STATUS REPORT TRANSMISSIONS IN NON-TERRESTRIAL NETWORKS

Abstract:

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit buffer status information using configured periodic uplink resources. For example, a base station may configure dedicated periodic uplink resources, periodic random access resources, or periodic uplink grants to enable the UE to transmit the buffer status information. In some cases, the periodic random access resources may enable the UE to transmit a first message of a four-step or two-step random access procedure to indicate the buffer status information. Additionally or alternatively, the base station may configure a type of scheduling request for the UE to transmit that can indicate whether a buffer size falls within a range, where the base station then can more accurately allocate uplink resources in an uplink grant for the UE to transmit the uplink data based on receiving this type of scheduling request.
