Patent ID: 8526464

Claim:
A method for wireless communication between a transmitting device and a receiving device over a discontinuous channel, the method comprising: estimating a first likelihood of channel collisions at start of a first discontinuous channel access interval, wherein channel collisions are based on transmission failures of information transmitted by the transmitting device in the discontinuous channel, wherein the estimated likelihood of channel collisions is set to be greater than a likelihood of channel collisions that was set for a previous discontinuous channel access interval, when a transmission failure of the information transmitted by the transmitting device in the discontinuous channel is detected during a portion of one or more previous channel access intervals, and wherein the discontinuous channel includes a no access interval during which the channel is not available for data transmission and an access interval during which the channel is available for data transmission; setting a size of a contention transmission window at start of a current discontinuous channel access interval after the first discontinuous channel access interval, according to the first estimated likelihood of channel collisions; estimating a second likelihood of channel collisions for a next discontinuous channel access interval after the current discontinuous channel access interval; and dynamically changing the size of the contention transmission window for the next discontinuous channel access interval, according to the second estimated likelihood of channel collisions, where the first or second estimated likelihood of channel collision is increased when a channel busy is detected during a portion of one or more previous channel intervals.
