Method and system for multi-user transmit opportunity for multi-user multiple-input-multiple-output wireless networks
First Claim
1. A method of wireless communication in a wireless communication system, comprising:
- maintaining data blocks at a wireless transmitting station for transmission to multiple wireless receiving stations over a wireless communication medium, wherein the data blocks are organized based on access categories;
each access category contending for a transmission opportunity period for access to the wireless communication medium; and
upon successful contention, during the transmission opportunity period, transmitting a data block of a primary access category from the transmitting station to a primary destination wireless receiving station, simultaneously transmitting a data block of a secondary access category from the transmitting station to a secondary destination wireless receiving station, over the wireless communication medium,wherein the primary access category is associated with an enhanced distributed channel access function (EDCAF) that gains channel access, and the secondary access category is not associated with the EDCAF that gains channel access.

Abstract
Wireless communication in a wireless system using a multiple user transmission opportunity is provided. Data blocks at a wireless station are transmitted to multiple wireless receivers over a shared wireless communication medium. The data blocks are organized in order of transmission priority based on access categories. Contention for access to the communication medium during a transmission opportunity period is based on a backoff timer of each access category and the transmission priority. Upon successful contention for a transmission opportunity period, during the transmission opportunity period, a data block of a primary access category is wirelessly transmitted from the wireless station to one or more primary destination wireless receivers. Simultaneously, a data block of a secondary access category is wirelessly transmitted from the wireless station to one or more secondary destination wireless receivers.

15. A wireless station for wireless communication in a wireless communication system, comprising:
-
a communication physical layer configured for wireless communication over a shared wireless communication medium; and a channel access module configured for maintaining data blocks for transmission to multiple wireless receivers over the wireless communication medium, wherein the data blocks are organized based on access categories;
wherein upon successful contention by each access category for a transmission opportunity period for access to the wireless communication medium, during the transmission opportunity period the channel access module utilizes the physical layer for transmitting a data block of a primary access category to a primary destination wireless receiver, while simultaneously transmitting a data block of a secondary access category to a secondary wireless receiver, over the wireless communication medium,wherein the primary access category is associated with an enhanced distributed channel access function (EDCAF) that gains channel access, and the secondary access category is not associated with the EDCAF that gains channel access. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A wireless communication system, comprising:
-
a wireless station; and a plurality of wireless receivers; the wireless station comprising; a communication physical layer configured for wireless communication over a shared wireless communication medium; and a channel access module configured for maintaining data blocks for transmission to the wireless receivers over the wireless communication medium, wherein the data blocks are organized based on access categories; wherein upon successful contention by each access category for a transmission opportunity period for access to the wireless communication medium, during the transmission opportunity period the channel access module utilizes the physical layer for transmitting a data block of a primary access category to a primary destination wireless receiver, while simultaneously transmitting a data block of a secondary access category to a secondary wireless receiver, over the wireless communication medium, wherein the primary access category is associated with an enhanced distributed channel access function (EDCAF) that gains channel access, and the secondary access category is not associated with the EDCAF that gains channel access. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
