Patent ID: 11974271

Abstract:
Methods, systems, and devices for wireless communications are described for configuring contention-free uplink resources and contention-based uplink resources as preconfigured uplink resources (PUR) available for a user equipment (UE) to transmit one or more uplink transmissions without a specific allocation for the uplink transmission from a base station. Each of two or more UEs may be configured with separate portions of contention-free PUR that each UE may use to transmit a relatively small first uplink communication that provides an indication that the UE will transmit a relatively larger second uplink communication using contention-based PUR. The UE may transmit a buffer status report (BSR) using the contention-free PUR. The first communication may provide an indication of one or more physical layer parameters associated with the second uplink communication. The UE may transmit the second uplink communication using the indicated one or more physical layer parameters via the contention-based uplink resource.
