Abstract
A UE receives a configuration for a message A (Msg A) physical random access channel (PRACH) over a resource block (RB) set for a two-step random access channel (RACH) operation and receives one or more parameters for a Msg A physical uplink shared channel (PUSCH) configuration. The UE transmits a Msg A in a configured Msg A PRACH occasion and a Msg A PUSCH resource based on an RB set for the Msg A PRACH and the one or more parameters for the Msg A PUSCH configuration.
Claims32
A method of wireless communication at a user equipment (UE), comprising:
- receiving a configuration for a message A (Msg A) physical random access channel (PRACH) over a resource block (RB) set for a two-step random access channel (RACH) operation;
- receiving one or more parameters for a Msg A physical uplink shared channel (PUSCH) configuration;
- and
- transmitting a Msg A PUSCH in a configured Msg A PRACH occasion and a Msg A PUSCH resource, the Msg A PUSCH resource being based on the RB set configured for the Msg A PRACH and the one or more parameters for the Msg A PUSCH configuration.
An apparatus for wireless communication at a user equipment (UE), comprising:
- memory;
- and
- at least one processor coupled to the memory and configured to cause the UE to:
- receive a configuration for a message A (Msg A) physical random access channel (PRACH) over a resource block (RB) set for a two-step random access channel (RACH) operation;
- receive one or more parameters for a Msg A physical uplink shared channel (PUSCH) configuration;
- and
- transmit the Msg A PUSCH in a configured Msg A PRACH occasion and a Msg A PUSCH resource, the Msg A PUSCH resource being based on the RB set configured for the Msg A PRACH and the one or more parameters for the configuration for the Msg A PUSCH.
A method of wireless communication at a base station, comprising:
- transmitting a configuration for a message A (Msg A) physical random access channel (PRACH) over a resource block (RB) sets for a two-step random access channel (RACH) operation;
- indicating one or more parameters for a Msg A physical uplink shared channel (PUSCH) configuration;
- and
- receiving a Msg A in a configured Msg A PRACH occasion and an identified Msg A PUSCH resource based on an RB set configured for the Msg A PRACH and the one or more parameters for the Msg A PUSCH configuration.
