Abstract:
1. A method of allocating subcarriers to subchannels in a telecommunications system which transmits a plurality of subchannels using subcarriers, the method comprising: a) defining a number of spatial channels each of which has a plurality of subchannels associated therewith; for each spatial channel: b) allocating a set of initial subcarriers among the subcarriers to each subchannel when a subchannnel quality measurement is initialized to zero, wherein the set of initial subcarriers is allocated to give a best subcarrier gain for each subchannel, and wherein the allocated subcarriers are no longer available for allocation to another subchannel and the set of initial subcarriers is less than all the subcarriers; c) after allocating the initial subcarriers to each subchannel in step b), detecting respective quality measurements for the subchannels; d) allocating a further set of unallocated subcarriers among the subcarriers to each of the subchannels associated with the spatial channel, in an order determined by the detected respective quality measurements of the subchannels; e) repeating steps c) and d) until all the subcarriers are allocated.
