Abstract
Techniques are disclosed involving media access. For instance, wireless connections may be assigned into one or more groups. The assignments may be based on interference characteristics. Connection(s) within each of these groups may have acceptable interference characteristics with each other. Further, media access may be granted based on these groups. For example, if a device wishes to communicate across one of the connections, access may be granted for concurrent connections among all connections in the corresponding group. The granting of such access may be performed by a centralized controller device, such as an access point.
Claims19
A method, comprising:
- directing measurements associated with a plurality of wireless connections;
- assigning each of the plurality of wireless connections to one or more groups based at least in part on the measurements;
- receiving a request to communicate across a particular one of the plurality of wireless connections;
- and
- in response to the request, granting access for communications across all wireless connections in the corresponding group.
An access point, comprising:
- a communications interface module, comprising one or more processors, to receive a request for communicating across a wireless communications link;
- and
- an access control module, comprising a second one or more processors, to determine a group corresponding to the wireless communications link based at least in part on a level of interference associated with the wireless connection link, and to generate a response to the request, the response to grant access for communications across all wireless connections in the corresponding group;
- wherein the communications interface module is to send the response to all wireless communications devices in the corresponding group.
A wireless communications device, comprising:
- an access request module to generate a request for communicating across a wireless connection;
- a communications interface module, comprising one or more processors, to send the request to an access point, and to receive a corresponding response from the access point, the response granting access for communications across all wireless connections in a group corresponding to the wireless connection, wherein the group is determined based at least in part on interference level measurements associated with the wireless connection.
An article comprising a non-transitory machine-accessible medium having stored thereon instructions that, when executed by a machine, cause the machine to:
- direct measurements associated with a plurality of wireless connections;
- assign each of the plurality of wireless connections to one or more groups based at least in part on the measurements;
- receive a request to communicate across a particular one of the plurality of wireless connections;
- and
- in response to the request, grant access for communications across all wireless connections in the group corresponding to the particular one of the plurality of wireless connections.
