Positioning assisted resource configuration and selection for two-step random access channel procedure

A user equipment (UE), comprising:

• a memory;
• at least one transceiver;
• and
• at least one processor coupled to the memory and the at least one transceiver, the at least one processor configured to:
• obtain one or more measurements for estimating a distance between the UE and a serving base station, one or more measurements for estimating a speed of the UE relative to the serving base station, or both;
• determine a resource configuration and a transmit power for a first physical random access channel (PRACH) preamble sequence, a resource configuration and a transmit power for a first physical uplink shared channel (PUSCH) resource unit (PRU), or both based at least on the distance between the UE and the serving base station, the speed of the UE relative to the serving base station, a radio resource control (RRC) state of the UE, or any combination thereof;
• transmit, via the at least one transceiver, to the serving base station over a first carrier frequency, a first message comprising the first PRACH preamble sequence on a first PRACH occasion and a first message payload on a PRU occasion based on the resource configuration associated with a beam index of SSB or RS, and the transmit power for the first PRACH preamble sequence, the resource configuration and the transmit power for the first PRU, or both;
• and
• receive, via the at least one transceiver, from the serving base station over the first carrier frequency via the at least one transceiver, a second message comprising information on a physical downlink control channel (PDCCH) and a second message payload on a physical downlink shared channel (PDSCH),
• wherein the PDCCH or the PDSCH have a quasi co-location relationship with a beam index of a synchronization signal block (SSB) or a reference signal (RS) associated with the first message.

A user equipment (UE), comprising:

• means for obtaining one or more measurements for estimating a distance between the UE and a serving base station, one or more measurements for estimating a speed of the UE relative to the serving base station, or both;
• means for determining a resource configuration and a transmit power for a first physical random access channel (PRACH) preamble sequence, a resource configuration and a transmit power for a first physical uplink shared channel (PUSCH) resource unit (PRU), or both based at least on the distance between the UE and the serving base station, the speed of the UE relative to the serving base station, a radio resource control (RRC) state of the UE, or any combination thereof;
• means for transmitting, to the serving base station over a first carrier frequency, a first message comprising the first PRACH preamble sequence on a PRACH occasion and a first message payload on a PRU occasion based on the determined resource configuration and transmit power for the first PRACH preamble sequence, the determined resource configuration and transmit power for the first PRU, or both;
• and
• means for receiving, from the serving base station over the first carrier frequency, a second message comprising information on a physical downlink control channel (PDCCH) and a second message payload on a physical downlink shared channel (PDSCH),
• wherein the PDCCH or the PDSCH have a quasi co-location relationship with a beam index of a synchronization signal block (SSB) or a reference signal (RS) associated with the first message.

A non-transitory computer-readable medium storing computer-executable instructions that, when executed by a user equipment (UE), cause the UE to:

• obtain one or more measurements for estimating a distance between the UE and a serving base station, one or more measurements for estimating a speed of the UE relative to the serving base station, or both;
• determine a resource configuration and a transmit power for a first physical random access channel (PRACH) preamble sequence, a resource configuration and a transmit power for a first physical uplink shared channel (PUSCH) resource unit (PRU), or both based at least on the distance between the UE and the serving base station, the speed of the UE relative to the serving base station, a radio resource control (RRC) state of the UE, or any combination thereof;
• transmit, to the serving base station over a first carrier frequency, a first message comprising the first PRACH preamble sequence on a PRACH occasion and a first message payload on a PRU occasion based on the determined resource configuration and transmit power for the first PRACH preamble sequence, the determined resource configuration and transmit power for the first PRU, or both;
• and
• receive, from the serving base station over the first carrier frequency, a second message comprising information on a physical downlink control channel (PDCCH) and a second message payload on a physical downlink shared channel (PDSCH),
• wherein the PDCCH or the PDSCH have a quasi co-location relationship with a beam index of a synchronization signal block (SSB) or a reference signal (RS) associated with the first message.
