Methods for reducing contention and/or handling channel access in a network










Image Number 3 for United States Patent #8050249.

A first information block is transmitted from a first terminal, the first terminal retaining access to a channel until either i) the first information block is acknowledged by a second terminal, or ii) at least a first predetermined period of time following transmission of the first information block expires, whichever is shorter. It is determined whether the first information block is acknowledged within the first predetermined period of time. A second information block is transmitted from the first terminal in response to the first information block being acknowledged within the first predetermined period of time. When the first information block has a first type, the first information block is retransmitted in response to the first information block not being acknowledged within the first predetermined period of time. When the first information block has a second type, retransmitting the first information block is attempted after waiting a second predetermined period of time.
