Starting random access channel occasion determination for multiple prach transmissions for wireless networks

A method, comprising:

• determining, by a user device in a wireless network, at least one starting random access channel occasion (RO), wherein each of the at least one starting RO is a first valid RO of an RO set for a physical random access (PRACH) transmission with preamble repetitions, wherein the determining the at least one starting RO is based at least on valid ROs, and the at least one starting RO comprises:
• a first subset of starting ROs, wherein the first subset of starting ROs are a first valid RO within a reference time period;
• and
• a second subset of starting ROs, wherein the second subset of starting ROs are separated from the first subset of starting ROs by a time offset between starting ROs;
• determining, by the user device, an RO set for the PRACH transmission with preamble repetitions based on the determined at least one starting RO, the determined RO set including one of the at least one starting RO;
• and
• transmitting, by the user device to a network node, the PRACH transmission with preamble repetitions using the determined RO set.

A non-transitory computer-readable storage medium comprising instructions stored thereon that, when executed by at least one processor, are configured to cause a computing system to perform:

• determining at least one starting random access channel occasion (RO), wherein each of the at least one starting RO is a first valid RO of an RO set for a physical random access (PRACH) transmission with preamble repetitions, wherein the determining the at least one starting RO is based at least on valid ROs, and the at least one starting RO comprises:
• a first subset of starting ROs, wherein the first subset of starting ROs are a first valid RO within a reference time period;
• and
• a second subset of starting ROs, wherein the second subset of starting ROs are separated from the first subset of starting ROs by a time offset between starting ROs;
• determining an RO set for the PRACH transmission with preamble repetitions based on the determined at least one starting RO, the determined RO set including one of the at least one starting RO;
• and
• transmitting to a network node, the PRACH transmission with preamble repetitions using the determined RO set.
