Abstract: Methods, devices, and non-transitory computer readable media are provided for configuring physical random access channel (PRACH) retransmissions in a wireless communication network. A PRACH trigger is received including a random access channel occasion (RO) indication. A PRACH preamble is transmitted to a base station during a first RO specified by the RO indication. One or more PRACH preamble repetitions are transmitted to the base station during a second RO specified by the RO indication. A random access response (RAR) is received from the base station in response to the PRACH preamble and/or the one or more PRACH preamble repetitions.

Abstract: Methods, systems, and devices for generating random access signals with bearer information are described. An exemplary method for wireless communication includes transmitting, by a terminal to a network node, a first message comprising a first preamble sequence associated with a first index that is from a first half of a set of indexes, and transmitting a second message comprising a second preamble sequence associated with a second index that is from a second half of the set of indexes, wherein the first index and the second index satisfy a constraint relationship.

Abstract: Enabling the co-existence of contention based random access (CBRA) and contention free random access (CFRA) is an effective technique to improve network flexibility and usage of network resources. In some embodiments, all available communication opportunities in the CBRA schedule and all available communication opportunities in the CFRA schedule may be used to generate a final schedule Different subsets of preamble indices are employed to ensure that both CBRA and CFRA communications can co-exist. In other embodiments, all available communication opportunities in the CBRA schedule, but only the dedicated communication opportunities in the CFRA schedule, may be used to generate a final schedule. As a result, a smaller subset of preamble indices is used.
