摘要： This invention prevents a periodically reported Rank Indicator from interfering with a similarly periodically reported wideband and subband channel quality indicator. Such interference is disadvantageous because it may eliminate wideband channel quality indicator reporting or eliminate each first bandwidth part of subband channel quality indicator reporting. Proper selection of the rank indicator reporting periodicity and offset relative to the wideband and subband channel quality indicator reporting periodicity prevents this interference.

摘要： A method of mapping data in a wireless communication system is disclosed. The method includes forming a first frame (504) having plural positions at a first transmitter (eNB 1, 200). The first frame has a first plurality of reference signals (500). A second frame (508) has plural positions corresponding to the plural positions of the first frame and is formed at a second transmitter (eNB 2, 450) that is remote from the first transmitter. The second frame has a second plurality of reference signals (506). A plurality of data signals (S1, S2) is inserted into the first frame at positions that are not occupied by either the first or second plurality of reference signals. The plurality of data signals (S1, S2) is inserted into the second frame at positions that are not occupied by either the first or second plurality of reference signals. The first and second frames are transmitted to a remote receiver (UE 1, 106).
