Claim Text:
1. A computer software product, the product comprising a tangible non-transitory computer-readable medium in which program instructions are stored, which instructions, when read by a processor, cause the processor to: calculate, based on signals received by a receiver from multiple cells that coordinate transmission of the signals with one another in a Cooperative Multipoint (CoMP) scheme, at least a first Channel Quality Indicator (CQI) and a second CQI for respective communication channels over which the signals are received, wherein the first CQI or the second CQI is calculated for a communication channel from one of the cells that is designated for fallback to single-transmission-point transmission to the receiver; differentially encode the second CQI relative to the first CQI; and provide the first CQI and the differentially-encoded second CQI to a transmitter for transmitting feedback information comprising the first CQI and the differentially-encoded second CQI.
