Method And Equipment For Information Transmission Based On Coordinated Multiple Point Transmission

摘要

An information transmission method and equipment based on CoMP transmission are described. A user equipment determines a main transmission point. The user equipment determines RANK information of the main transmission point as well as channel state information corresponding to the RANK information. The user equipment sends the RANK information of the main transmission point and the channel state information to a network side equipment. The UE reports channel state information of limited RANK of every transmission point, channel state information of unlimited RANK of the main transmission point, and relative phase information between the transmission points, etc., to the network side equipment.

1. A method for information transmission based on coordinated multipoint transmission, comprising:
determining, by a user equipment (UE), a main transmission point; determining, by the UE, RANK information of the main transmission point, and channel state information corresponding to the RANK information, wherein the RANK refers to a number of spatial multiplexing data layers; and sending, by the UE, the RANK information and the channel state information of the main transmission point to a network side equipment; wherein the method further comprises: receiving, by the UE, configuration information of the measurement set from the network side equipment, wherein the configuration information of the measurement set comprises identification information of a transmission point and pilot configuration information of the transmission point, or comprises pilot configuration information of the transmission point; taking, by the UE, the RANK information of the main transmission point as RANK information of the transmission point, and determining the channel state information corresponding to the RANK information of the transmission point; and sending, by the UE, the channel state information corresponding to the RANK information of the transmission point to the network side equipment.
