US 12,604,339 B2 · Uplink transmissions with repetition during contention-free random access

Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, a downlink communication that indicates a random access response (RAR) or a fallback RAR, the downlink communication being received during a contention-free random access (CFRA) involving the UE and the network node. The UE may transmit, to the network node and based at least in part on an uplink grant in the RAR or in the fallback RAR, an uplink transmission with a repetition, the uplink transmission with the repetition being transmitted during the CFRA involving the UE and the network node. Numerous other aspects are described.

Dependent claims

An apparatus for wireless communication at a user equipment (UE), comprising:

one or more memories;
and
one or more processors coupled to the one or more memories, the one or more processors individually or collectively configured to:
receive, from a network node and during a contention-free random access (CFRA) involving the UE and the network node, a downlink communication that indicates a random access response (RAR) or a fallback RAR;
and
transmit, to the network node during the CFRA and based at least in part on an uplink grant in the RAR or in the fallback RAR, an uplink transmission with a repetition, wherein a same repetition factor is used for the uplink transmission during the CFRA as a prior contention-based random access (CBRA) transmission between the UE and the network node.
