A method for wireless communication, comprising: determining at a user equipment, UE, first channel information related to at least one cell among a plurality of cells in a coordinated multi-point, CoMP, measurement set of the UE, wherein the determining the first channel information comprises: selecting at the UE a subset of a plurality of cells in the CoMP measurement set, and determining the first channel information for the selected subset of the plurality of cells; determining, by the UE, a first channel information reporting mode, based on various factors, the factors being a number of cells in the CoMP measurement set, a number of subbands, channel conditions, reporting capabilities of the UE, or a reporting interval for channel information, the first channel information reporting mode being one of a plurality of channel information reporting modes available for reporting channel information for CoMP data transmission, and wherein each of the plurality of channel information reporting modes describes the set of channel information to be transmitted, in which different channel information reporting modes contain channel information for different combinations of all or a subset of layers, all or a subset of subbands, and all or a subset of the plurality of cells in the CoMP measurement set; sending, by the UE, the first channel information in accordance with the first channel information reporting mode to one or more cells in the CoMP measurement set; determining, by the UE, second channel information related to multiple cells in the CoMP measurement set; determining, by the UE, a second channel information reporting mode to use by the UE, the second channel information reporting mode being another one of the plurality of channel information reporting modes; and sending, by the UE, the second channel information in accordance with the second channel information reporting mode to the one or more cells in the CoMP measurement set. determining at a user equipment, UE, first channel information related to at least one cell among a plurality of cells in a coordinated multi-point, CoMP, measurement set of the UE, wherein the determining the first channel information comprises: selecting at the UE a subset of a plurality of cells in the CoMP measurement set, and determining the first channel information for the selected subset of the plurality of cells; selecting at the UE a subset of a plurality of cells in the CoMP measurement set, and determining the first channel information for the selected subset of the plurality of cells; determining, by the UE, a first channel information reporting mode, based on various factors, the factors being a number of cells in the CoMP measurement set, a number of subbands, channel conditions, reporting capabilities of the UE, or a reporting interval for channel information, the first channel information reporting mode being one of a plurality of channel information reporting modes available for reporting channel information for CoMP data transmission, and wherein each of the plurality of channel information reporting modes describes the set of channel information to be transmitted, in which different channel information reporting modes contain channel information for different combinations of all or a subset of layers, all or a subset of subbands, and all or a subset of the plurality of cells in the CoMP measurement set; sending, by the UE, the first channel information in accordance with the first channel information reporting mode to one or more cells in the CoMP measurement set; determining, by the UE, second channel information related to multiple cells in the CoMP measurement set; determining, by the UE, a second channel information reporting mode to use by the UE, the second channel information reporting mode being another one of the plurality of channel information reporting modes; and sending, by the UE, the second channel information in accordance with the second channel information reporting mode to the one or more cells in the CoMP measurement set.
