Interference-improved uplink data rates for a group of mobile stations transmitting to a base station

摘要

A base station maximizes an uplink data transmission rate from multiple mobiles treated by the base station as a virtual single uplink transmitter. The base station identifies a set of mobile stations as a candidate transmitting set and determines a transmit power allowable from the mobile stations in the candidate transmitting set. A subset of those mobile stations in the candidate transmitting set is identified. Uplink data transmission rates are assigned and communicated to the subset of mobile stations in the candidate transmitting set so as to optimize a total number of bits processed by the base station associated with the uplink transmissions received from the subset of candidate mobile stations. The optimization may accomplish one or more objectives in addition to optimizing the total number of bits processed.

1. A method implemented in a base station communicating in a radio communications system, comprising:
identifying, from among a plurality of mobile stations requesting service, a candidate transmitting set comprising a set of candidate mobile stations based on a ranking of signal-to-interference-plus noise ratios associated with respective candidate mobile stations; identifying all possible subsets of the candidate mobile stations in the candidate transmitting set; determining a total transmit power allowable for the possible subsets of candidate mobile stations; selecting, from among the plurality of possible subsets, a subset of the candidate mobile stations that maximizes a total number of bits processed by the base station from uplink transmissions transmitted by the selected subset in accordance with the total transmit power allowable; assigning transmission resources to each of the mobile stations in the selected subset of candidate mobile stations; and receiving the uplink transmissions from the selected subset of the candidate mobile stations.
