Abstract
A signaling mechanism is provided that includes a restricted random access resource unit (XRA RU) that restricts uplink random access, such as by using Uplink Orthogonal frequency-division multiple access-based Random Access (UORA), to a subset of a plurality of stations that are associated with an Access Point (AP). In one aspect, an AP allocates a resource unit as an XRA RU that restricts uplink random access to a subset of a plurality of stations (STAs) that are associated with the AP. The AP transmits an uplink trigger that includes the XRA RU. The AP restricts use of the XRA RU to the subset of the plurality of STAs. In this way, STAs of the subset can attempt contention-based random access with the XRA RU while other STAs are prevented from attempting random access with the XRA RU.
