Abstract
Methods, receivers, and computer program products for defining asymmetric decision regions of a symbol space to interpret transmitted power control commands are disclosed. A method of determining transmitted power control commands at a receiver can include defining a first decision region of a symbol space associated with a first power control command at the receiver and a second decision region of the symbol space associated with a second power control command at the receiver where the first and second regions are asymmetric with one another. Methods of determining a transmitted power control command during soft handover mode in a wideband code division multiple access communications system are also discussed wherein a first determination of a combined power control command received from a plurality of transmitters can be combined with a second determination of the combined power control command received from the plurality of transmitters to provide a combined power control command. Related circuits are disclosed as well.
