Abstract:
1. An apparatus for wireless communication, comprising: a plurality of antennas; and a processing system configured to: contend for access to a multiple access medium using a minimum contention window size that is equal to a number based on a minimum contention window size for an access class divided by a number of a plurality of nodes with data to transmit that belongs to the access class; transmit a request spatial division multiple access (RSDMA) message identifying the plurality of nodes to transmit a request to send a spatial division multiplexed transmission; allocate a plurality of slots for receiving requests to send a spatial division multiplexed transmission from the plurality of nodes; receive the requests to send a spatial division multiplexed transmission from one or more of the plurality of nodes over the multiple access medium; and initiate spatial division multiplexed transmission from the one or more of the plurality of nodes based on a metric related to the one or more of the plurality of nodes.
