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, physical random access channel (PRACH) transmission counting control information. The UE may transmit, to the network node, multiple PRACH transmissions in a random access procedure in accordance with the PRACH transmission counting control information. Numerous other aspects are described.
Claims19
A user equipment (UE) for wireless communication, comprising:
- a memory;
- transceiver;
- and
- one or more processors, coupled to the memory and the transceiver, configured to:
- receive, via the transceiver and from a network node, physical random access channel (PRACH) transmission counting control information;
- and
- transmit, via the transceiver and to the network node, multiple PRACH transmissions in a random access procedure in accordance with the PRACH transmission counting control information.

A user equipment (UE) for wireless communication, comprising:
- a memory;
- a transceiver;
- and
- one or more processors, coupled to the memory and the transceiver, configured to:
- receive, via the transceiver and from a network node while operating in a connected state, configuration information that indicates dedicated random access channel (RACH) resources for multiple physical random access channel (PRACH) transmissions;
- and
- transmit, via the transceiver and to the network node, the multiple PRACH transmissions, in a contention based random access (CBRA) procedure, using the dedicated RACH resources.
A UE for wireless communication, comprising:
- a memory;
- a transceiver;
- and
- one or more processors, coupled to the memory and the transceiver, configured to:
- receive, via the transceiver and from a first network node, a configuration for a dual active protocol stack (DAPS) based handover from the first network node to a second network node;
- transmit, via the transceiver and during the DAPS based handover, an uplink transmission to the second network node;
- and
- transmit, via the transceiver and during the DAPS based handover, multiple physical random access channel (PRACH) transmissions to the first network node in respective random access channel (RACH) occasions, in accordance with a rule for counting a PRACH transmission that is dropped in connection with a RACH occasion associated with the PRACH transmission overlapping in time with the uplink transmission to the second network node.
