Multipoll for QoS-Driven wireless LANs
First Claim
1. A method for providing quality of service (QoS)-driven channel access within a basic service set (BSS) in a wireless network, the method comprising:
- a) determining at a point coordinator (PC) station of the BSS whether at least one of up-stream traffic and side-stream traffic is scheduled to be transmitted from at least one non-PC station in the BSS;
b) determining at the PC station whether at least one transmission opportunity (TO) is available during a contention free period (CFP) of a superframe for transmitting one of up-stream traffic and side-stream traffic in the BSS, the superframe containing the CFP and a contention period (CP);
c) allocating at least one available TO to a selected non-PC station having at least one of up-stream traffic and side-stream traffic to transmit; and
d) sending from the PC station a multipoll frame allocating at least two TOs and identifying each respective allocated TO by;
d1) a duration time; and
d1) one of a virtual stream identifier (VSID) and an association identifier (AID).

Abstract
A method and a system are disclosed for providing quality of service (QoS)-driven channel access within a basic service set (BSS) in a wireless network. A point coordinator (PC) station determines whether at least one of upstream traffic and side-stream traffic is scheduled to be transmitted from at least one non-PC station At least one available TO is allocated to each selected non-PC having at least one traffic to transmit. A multipoll frame containing information relating to at least two allocated TOs is then sent from the PC station containing information relating to each allocated TO.

15. A point coordinator (PC) station in a basic service set (BSS) in a wireless network, the PC station comprising:
-
a) a frame scheduling entity (FSE) determining whether at least one of up-stream traffic and side-stream traffic is scheduled to be transmitted from at least one non-PC station in the BSS, the FSE determining whether at least one transmission opportunity (TO) is available during a contention free period (CFP) of a superframe for transmitting one of up-stream traffic and side-stream traffic in the BSS, the superframe containing the CFP and a contention period (CP), the FSE allocating at least one available TO to a selected non-PC having at least one of up-stream traffic and side-stream traffic to transmit; and b) a transmitter sending from the PC station a multipoll frame allocating at least two TOs and identifying each respective allocated TO by; b1) a duration time; and b2) one of a virtual stream identifier (VSID) and an association identifier (AID). - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
