Abstract
Techniques and apparatus for avoiding uplink orthogonal frequency division multiple access (OFDMA)-based random access (UORA) collisions for uplink transmissions are described. An example technique includes obtaining, by a wireless device, information indicating (i) a UORA resource unit (RU) assigned to a multi-user (MU) group including the wireless device and (ii) a number of spatial streams associated with the MU group. A respective user position associated with the wireless device within the MU group is determined from multiple user positions. A spatial stream of the number of spatial streams is selected based on the user position. Uplink data is transmitted on the UORA RU using the spatial stream.
