Accessing channels in a multi-channel communication system

摘要

In a method of determining channel availability in a wireless communication network utilizing at least first and second sub-channels, a first signal is received via a first channel. The first signal includes first access control information indicating expected utilization of the first channel. The first channel includes the first sub-channel. A first sub-channel availability indicator is updated based on the first access control information. The first sub-channel availability indicator indicates expected utilization of the first sub-channel. A second signal is received via a second channel. The second signal includes second access control information indicating expected utilization of the second channel. The second channel includes the second sub-channel. A second sub-channel availability indicator is updated based on the second access control information. The second sub-channel availability indicator indicates expected utilization of the second sub-channel. A transmission channel is determined based on the first and second sub-channel availability indicators.

1. A method of determining channel availability in a wireless communication network that utilizes a plurality of sub-channels, wherein multiple sub-channels in the plurality of sub-channels can be joined to form a composite channel, and wherein the plurality of sub-channels includes at least a first sub-channel and a second sub-channel, the method comprising:
receiving a first signal via a first channel, wherein
the first signal includes first access control information indicating an expected utilization of the first channel, andthe first channel includes the first sub-channel; updating a first sub-channel availability indicator based on the first access control information, wherein the first sub-channel availability indicator indicates an expected utilization of the first sub-channel; receiving a second signal via a second channel, wherein
the second signal includes second access control information indicating an expected utilization of the second channel, andthe second channel includes the second sub-channel; updating a second sub-channel availability indicator based on the second access control information, wherein the second sub-channel availability indicator indicates an expected utilization of the second sub-channel; and determining a transmission channel based on the first sub-channel availability indicator and the second sub-channel availability indicator.
