Methods and arrangements for channel access in wireless networks

摘要

Embodiments may define traffic priorities to facilitate transmissions for wireless communications devices. Many embodiments comprise MAC sublayer logic to generate and transmit management frames such as beacon frames, association response frames, reassociation response frames, and probe response frames with an access category for low power consumption stations or sensor stations comprising a parameter record defining a contention window that is the earliest contention window to open amongst contention windows defined for the access categories for traffic. In some embodiments, the MAC sublayer logic may store the parameter record sets for access categories in memory, in logic, or in another manner that facilitates transmission of the frames. Some embodiments may receive and detect communications with frames comprising the access categories and store a parameter set for one or more of the access categories in a management information base.

主权项

1. A method comprising:
generating, by a processor of a medium access control sublayer logic, a frame comprising parameter records to change default management information base (MIB) attribute values for an enhanced distributed channel access (EDCA) Parameter Set element having parameter values for defining access categories of data traffic including best efforts traffic and sensor traffic, the parameter values including arbitration interframe space numbers and one or more contention window values for the access categories, wherein an arbitration interframe space number setting for a sensor access category is lower than an arbitration interframe space number for a best efforts access category for the default MIB attribute value, wherein the sensor access category provides the sensor traffic with priority over the best efforts traffic during competition in a first round of a contention window; and creating, by physical layer device, a physical layer protocol data unit comprising the frame with a preamble for transmission.
