Abstract:
1. A method of multiple access communications over two or more communication links in different cells, the method comprising: determining a variability of one or more channel characteristics of the two or more communication links in different cells, wherein each communication link is associated with a user equipment and wherein the variability is determined using correlation estimates; changing, at a base station, a rate sensitivity of a communication link when the determined variability exceeds a rate threshold; grouping each user equipment into either a slowly varying group or a rapidly varying group according to the determined variability of the associated communication link, wherein when the determined variability is above a higher limit a user equipment is classified as rapidly varying and when the determined variability is below a lower limit a user equipment is classified as slowly varying; and, allocating different orthogonal channels to the slowly varying and rapidly varying user equipment groups such that the impact of a user equipment in the rapidly varying group in one cell on a user equipment in the slowly varying group in a neighboring cell is eliminated or substantially reduced.
