Abstract:
1. A method for allocating transmission rates in a wireless network, comprising the steps of associating transmitters with corresponding receivers for communicating on an interference channel in the wireless network, and allocating a transmission rate to each transmitter for decoding by its corresponding receiver, the allocated transmission rate being equal to a desired rate of a fixed user rate and being no less than a minimum rate of a variable user rate; wherein said allocating comprises a sequential allocation meeting the minimum rate requirement of all users and assigning excess rates to variable rate users in a sequential fashion according to specified priorities; said sequential allocation comprising, from each receiver, using a rate-allocation vector as an input to obtain a rate recommendation for a specified variable rate user, said using the rate allocation vector as an input to obtain the rate recommendation comprising a procedure implemented at a specified receiver and responsive to a complexity constraint for a successive group decoder at the specified receiver, channel response vector seen from each transmitter by the specified receiver, a scalar which specifies the index of a variable rate user for which the rate recommendation is being made and a rate-allocation vector that contains the current assigned rates of other users.
