Patent ID: 8638737

Claim:
A method for use in a wireless communications system to enable dynamic selection of k sub-MAPs, k being an integer that is equal to 1, . . . N, where N is a positive integer, and of rates for transmitting said k sub-MAPs within at least one communication frame, wherein said k sub-MAPs are transmitted from a base station to at least one subscriber device, said method comprising: a. for the at least one communication frame comprised within a first interval of time, retrieving information on statistical distribution of downlink (DL) channel rates for a group of subscriber devices; b. based on said information, selecting k and corresponding transmission rates for said k sub-MAPs, to minimize total amount of resources that should be allocated for transmitting MAP and sub-MAPs within said at least one communication frame comprised within said first time interval and/or within a second interval of time that proceeds said first interval of time, and estimating resources required for transmission of MAPs and sub-MAPs had the selected sub-MAPs transmission rates been applied and determining if the estimated resources for the selected transmission rates is lower than the resources required for MAPs transmission when no sub-MAPs are transmitted within a corresponding interval of time; c. transmitting said k sub-MAPs at the selected corresponding transmission rates in one or more communication frames comprised within said first time interval and/or within said second interval of time that proceeds said first interval of time.
