Abstract
Certain aspects of the present disclosure provide methods and apparatus for managing channel access using multiple backoff counters.
Claims11
An apparatus for wireless communications, comprising:
- a processing system configured to maintain a number of one or more backoff counters, each backoff counter being used for flow control of one or more packets from a set of one or more queues, each queue being associated with an access class (AC), to adjust a probability of one or more of the ACs to access a wireless medium based on the number of backoff counters, and to perform flow control of the one or more packets from the set of queues after the adjustment;
- and
- a first interface for outputting the one or more packets for transmission on the wireless medium.
A method for wireless communications, comprising:
- maintaining a number of one or more backoff counters, each backoff counter being used for flow control of one or more packets from a set of one or more queues, each queue being associated with an access class (AC);
- adjusting a probability of one or more of the ACs to access a wireless medium based on the number of backoff counters, and to perform flow control of the one or more packets from the set of queues after the adjustment;
- and
- outputting the one or more packets for transmission on the wireless medium.
