Abstract
Systems and methods for selecting medium access parameters for each communication session are disclosed. In one aspect an access point includes a processor configured to select a value for a medium access parameter for a particular communication session between the access point and a wireless station.
Claims16
An access point for wireless communications, comprising:
- a processor configured to
- select a value for a medium access parameter for each individual communication session between the access point and each of a plurality of wireless stations, the medium access parameter comprising at least one of a clear channel assessment threshold and a minimum duration for contention window backoff period, the value for each medium access parameter being selected based at least in part on a path loss between the access point and each of the plurality of wireless stations, selecting the value comprising:
- select a first value for the medium access parameter for a first communication session between the access point and a first wireless station within the plurality of wireless stations, and
- select a second value for the medium access parameter for a second communication session between the access point and a second wireless station within the plurality of wireless stations, the first value being different from the second value, wherein the processor is configured to select a lower value for the clear channel assessment threshold based at least on determining whether the access point is increasing a transmission power level;
- and
- a transceiver configured to communicate with each of the plurality of wireless stations using the selected value for the medium access parameter for each individual communication session.

A method of wireless communication, comprising:
- selecting, at an access point, a value for a medium access parameter for each individual communication session between the access point and each of a plurality of wireless stations, the medium access parameter comprising at least one of a clear channel assessment threshold and a minimum duration for contention window backoff period, the value for each medium access parameter being selected based at least in art on a path loss between the access point and each of the plurality of wireless stations, selecting the value comprising:
- selecting, at the access point, a first value for the medium access parameter for a first communication session between the access point and a first wireless station within the plurality of wireless stations, and
- selecting, at the access point, a second value for the medium access parameter for a second communication session between the access point and a second wireless station within the plurality of wireless stations, the first value being different from the second value, wherein a processor is configured to select a lower value for the clear channel assessment threshold based at least on determining whether the access point is increasing a transmission power level;
- and
- communicating, at the access point, with each of the plurality of wireless stations using the selected value for the medium access parameter for each individual communication session.

An access point for wireless communications, comprising:
- means for selecting, at an access point, a value for a medium access parameter for each individual communication session between the access point and each of a plurality of wireless stations, the medium access parameter comprising at least one of a clear channel assessment threshold and a minimum duration for contention window backoff period, the value for each medium access parameter being selected based at least in cart on a path loss between the access point and each of the plurality of wireless stations, the means for selecting the value comprising:
- means for selecting a first value for the medium access parameter associated with a first communication session between the access point and a first wireless station of the plurality of wireless stations, and
- means for selecting a second value associated with the medium access parameter for a second communication session between the access point and a second wireless station of the plurality of wireless stations, the first value being different from the second value, wherein the means for selecting is configured to select a lower value for the clear channel assessment threshold based at least on determining whether the access point is increasing a transmission power level;
- and
- means for communicating with each of the plurality of wireless stations using the selected value for the medium access parameter for each individual communication session.
