Title:
Wireless communications which have a primary access category and a secondary access category
Document Type and Number:
Japanese Patent JP5910948
Kind Code:
B2
Abstract:
Systems and techniques relating to wireless communications are described. A described technique includes determining a primary access category for a transmission opportunity (TXOP) to transmit data to a primary wireless communication device based on a first back-off timer associated with the primary access category; determining a secondary access category for the TXOP to transmit data to a secondary wireless communication device; and transmitting, during the TXOP, spatially steered streams that concurrently provide separate data to respective devices comprising the primary and the secondary device. The technique can include controlling a contention window and a second back-off timer associated with the secondary access category, where the second back-off timer is not penalized for a communication failure associated with the primary access category or the secondary access category during the TXOP, and where the contention window is not penalized for the communication failure associated with the secondary access category during the TXOP.
