Abstract
Methods, systems, and devices for unsourced random access via channel clustering in orthogonal time frequency space domain are described. Multiple user equipments (UEs) may transmit encoded message segments according to randomly selected coding sequences from a codebook. UEs may transmit the message segments over a series of slots. A network entity may identify the coding sequences for each message segment and assign each message segment to a respective delay Doppler domain cluster based on message segments having a same or similar time delay and Doppler shift. The network entity may then identify each message by combining the messages segments of each delay Doppler domain cluster and decoding the message.
