摘要： Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. An AP may be configurable to operate as a master AP of a multi-AP group comprising the master AP and one or more satellite APs. The master AP may select, from the multi-AP group, a set of APs that is to communicate with a STA in accordance with joint processing. The master AP may allocate one or more spatial streams to each of the APs of the set of APs for a joint transmission of a null data packet (NDP) to the STA for channel sounding. The master AP may transmit an NDP announcement (NDPA) that indicates that the APs of the set of APs are to perform the joint transmission of the NDP.

摘要： Computing readable media, apparatuses, and methods for random access with carrier sensing are disclosed. An apparatus is disclosed including processing circuitry configured to: decode a trigger frame, the trigger frame to indicate resource units (RUs) for random access and to indicate if a carrier sense (CS) is to be performed.

A HEW station is disclosed that may include circuitry configured to receive a trigger frame with a first duration from a HEW master station, determine a second duration based on the first duration, generate a packet with the second duration, and transmit the packet with the second duration in an uplink transmission opportunity to the master station in accordance with at least one from the following group: orthogonal frequency division multiple-access and multiple-user multiple-input multiple-output. The trigger frame may include a resource map and the HEW station may transmit the packet on a channel indicated in the resource map.
