Abstract:
1. A method comprising: generating for a client device associated with an access point, a partial association identifier based on an association identifier assigned to the client device and a hash of a basic service set identifier the client device is associated with; and transmitting a packet to the client device, the packet comprising the partial association identifier, wherein the partial association identifier indicates that the packet is intended for the client device; wherein the hash of the basic service set identifier comprises an offset computed based on the basic service set identifier and an exclusive OR of bits of the basic service set identifier and wherein the partial association identifier is equal to a modulo sum of a set number of least significant bits of the association identifier and the offset computed based on the basic service set identifier; wherein generating the partial association identifier for the client device comprises calculating the partial association identifier that reduces a likelihood of partial association identifier collisions for overlapped access points.
