Determination for uplink repetitions

A second apparatus comprising:

• at least one processor;
• and
• at least one memory storing instructions that, when executed by the at least one processor, cause the second apparatus at least to:
• transmit, to a first apparatus, configuration information indicating a first plurality of physical random access channel (PRACH) occasions comprising PRACH occasions in uplink resource and a second plurality of PRACH occasions comprising PRACH occasions in sub-band non-overlapping full-duplex (SBFD) resource;
• monitor, based on the configuration information and for each frequency resource index for frequency multiplexed PRACH occasions, a PRACH transmission with preamble repetitions on a set of PRACH occasions for the PRACH transmission, wherein a starting PRACH occasion of the set is determined from the PRACH occasions in uplink resource, and the PRACH occasions in SBFD resource;
• and
• receive, from the first apparatus, the PRACH transmission based at least in part on the starting PRACH occasion of the set.

A method comprising:

• receiving, at a first apparatus and from a second apparatus, configuration information indicating a first plurality of physical random access channel (PRACH) occasions comprising PRACH occasions in uplink resource and a second plurality PRACH occasions comprising PRACH occasions in sub-band non-overlapping full-duplex (SBFD) resource;
• determining, based on the configuration information, and for each frequency resource index for frequency multiplexed PRACH occasions, a starting PRACH occasion of a set of PRACH occasions for a PRACH transmission with preamble repetitions from the PRACH occasions in uplink resource and the PRACH occasions in SBFD resource;
• wherein the set of PRACH occasions for transmission with preamble repetitions is determined by skipping the PRACH occasions in SBFD resource or by counting only the first PRACH occasions in uplink resource;
• or
• wherein the set of PRACH occasions for transmission with preamble repetitions is determined by skipping the PRACH occasions in uplink resource or by counting only the second PRACH occasions in SBFD resource;
• and
• performing, to the second apparatus, the PRACH transmission based at least in part on the starting PRACH occasion of the set.
