Wireless Communication Rate Allocation on a Gaussian Interference Channel

摘要

There is provided a method for allocating transmission rates in a wireless network, includes 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. The step of allocating can include a sequential allocation that meets the minimum rate requirement of all users and assigns excess rates to variable rate users in a sequential fashion according to specified priorities. The step of allocating can include a parallel symmetric rate allocation when all variable rate users have the same priority and that meets minimum rate requirements of all users and is symmetric fair. The step of allocating can include a parallel iterative rate allocation with the sequence of rate allocations obtained for each user being non-decreasing and a rate allocation vector obtained after each iteration meets minimum rate requirements for all users and is max-min fair when all variable rate users have the same priority.
