Random access message transmission schemes with cyclic shift

A network entity, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the network entity to:
• detect a first random access path and a second random access path based at least in part on one or more transmissions of a first random access preamble obtained during a first random access occasion;
• output, based at least in part on detecting the first random access path and the second random access path, a first response message comprising information associated with one or more estimated random access paths comprising at least the first random access path and the second random access path, the information comprising an indication of a first set of resources for transmitting a random access message of a first random access procedure;
• obtain a first random access message associated with the first random access path based at least in part on outputting the first response message;
• and
• output a second response message associated with the second random access path based at least in part on failing to receive a second random access message associated with the second random access path, the second response message comprising second information associated with a second set of resources for transmitting a second random access preamble associated with a second random access procedure.

A method for wireless communications at a user equipment (UE), comprising:

• transmitting a random access preamble via a random access occasion in accordance with a cyclic shift of a set of candidate cyclic shifts and with a cyclic shift offset of a set of candidate cyclic shift offsets;
• receiving, based at least in part on transmitting the random access preamble, a first response message indicating information associated with one or more estimated random access paths corresponding to one or more random access preambles received by a network entity within a duration, the information comprising an indication of a set of resources for transmitting a random access message of a random access procedure;
• refraining from transmitting the random access message when two or more estimated random access paths indicated by the first response message are detected within a threshold duration of the cyclic shift and the cyclic shift offset;
• and
• receiving, based at least in part on refraining from transmitting the random access message, a second response message comprising second information indicating a second set of resources for transmitting a second random access preamble associated with a second random access procedure.
