Abstract:
Methods, systems, and devices for wireless communications are described. In some examples, a base station may recover a UE from a Msg3 failure during an RA procedure. During the RA procedure, the base station may transmit a RAR message to the UE and in response to the RAR message the UE may transmit an uplink message (e.g., Msg3) to the base station over a first resource indicated in the RAR message. If the base station fails to decode or receive the uplink message over the first resource, the base station may transmit a grant to the UE indicating a second resource for retransmitting the uplink message and the UE may retransmit uplink message to the base station according to the grant.
