Abstract:
1. A method comprising: identifying a set of mobile terminals and a set of base stations designated to participate in a coordinated multipoint transmission protocol in a communication network; assigning, for each of a plurality of sectors of a designated base station, one or more unique downlink communication resource blocks to each of a plurality of designated mobile terminals that are located in a first sector of the designated base station; and assigning the same one or more unique downlink communication resource blocks assigned to a given one of the terminals in the first sector to a designated mobile terminal in a second sector of the designated base station such that each designated mobile terminal in the first and second sectors of the designated base station: (i) performs a channel state estimation process in response to respective signals received from the designated base stations in the one or more unique downlink communication resource blocks assigned to that designated mobile terminal; and (ii) transmits resulting channel state information back to at least one of the designated base stations; wherein the one or more unique downlink communication resource blocks are assigned such that a minimum size of a contiguous frequency allocation to each designated mobile terminal in the first sector is set equal to or greater than a coherence bandwidth attributable to the first sector.
