Abstract
Techniques for media access in wireless networks are disclosed. For instance, embodiments may provide a time interval for accessing a wireless communications channel. In addition, embodiments may prevent channel access during the time interval by stations incapable of employing a first channel access technique. This access technique employs an access probability P.
Claims12
An apparatus, comprising:
- an access selection module to:
- identify a timing format comprising a first time interval and a second time interval select a channel access technique from two or more channel access techniques based on a timing format,
- select a first channel access technique during the first time interval, the first channel access technique to:
- determine whether a randomly generated value is greater than or equal to an access probability,
- in response to determining that the randomly generated value is great than or equal to the access probability, perform carrier sensing, and
- in response to determining that the randomly generated value is less than the access probability, forego performing carrier sensing, and
- select a second channel access technique during the second time interval;
- and
- a transceiver to access a channel according to the first channel access technique during the first time interval and the second channel access technique during the second time interval.
