Method and apparatus for spatial setting determination during a random access procedure

A user equipment (UE), comprising:

• a processor configured to identify a set of physical random access channel (PRACH) occasions for PRACH repetitions, wherein N PRACH occasions are included in the set of PRACH occasions;
• and
• a transceiver operably coupled to the processor, the transceiver configured to:
• perform a transmission of N PRACH repetitions on the set of PRACH occasions;
• receive a physical downlink control channel (PDCCH) scheduling a reception of a physical downlink shared channel (PDSCH) based on a random access radio network temporary identifier (RA-RNTI), wherein the RA-RNTI is computed based on a last PRACH occasion in the set of PRACH occasions;
• receive the PDSCH based on the PDCCH, wherein a random access response (RAR) is included in the PDSCH and wherein the RAR includes an indication for a first PRACH occasion or a second PRACH occasion;
• and
• transmit a first PUSCH, and any PUSCH after the first PUSCH until reception of information indicating use of a spatial setting, using:
• a first spatial setting, when the indication is for the first PRACH occasion from the set of PRACH occasions, and
• a second spatial setting, when the indication is for the second PRACH occasion from the set of PRACH occasions.

A base station (BS), comprising:

• a processor;
• and
• a transceiver operably coupled to the processor, the transceiver configured to:
• receive N physical random access channel (PRACH) repetitions on a set of PRACH occasions, wherein N PRACH occasions are included in the set of PRACH occasions;
• transmit a physical downlink control channel (PDCCH) scheduling a transmission of a physical downlink shared channel (PDSCH) based on a random access radio network temporary identifier (RA-RNTI), wherein the RA-RNTI is computed based on a last PRACH occasion in the set of PRACH occasions;
• transmit the PDSCH based on the PDCCH, wherein a random access response (RAR) is included in the PDSCH and wherein the RAR includes an indication for a first PRACH occasion or a second PRACH occasion;
• and
• receive a first PUSCH, and any PUSCH after the first PUSCH until reception of information indicating use of a spatial setting, using:
• a first spatial setting, when the indication is for the first PRACH occasion from the set of PRACH occasions, and
• a second spatial setting, when the indication is for the second PRACH occasion from the set of PRACH occasions.
