摘要： A method, a network device, and a system for determining resource mapping in CoMP transmission are disclosed. The method includes: the cooperative cells that perform CoMP transmission for a UE negotiate a mapping rule used by the cooperative cells when the status of the CoMP transmission of the UE changes, where the mapping rule includes the number of and position of OFDM symbols allocated to a PDCCH domain and/or a data channel domain; and the negotiated mapping rule is notified to the UE. In this embodiment, before the downlink signals are transmitted, the mapping rule used by each cooperative cell for CoMP transmission is negotiated between the cooperative cells, and therefore, the UE can accurately receive the signal sent by multiple cooperative cells and the performance of CoMP transmission in the system is improved.

摘要： A method and an apparatus for implementing channel measurement are disclosed in the present invention. The method includes: determining an antenna port subset, which is required to be measured, for a UE according to current state information of the user equipment UE; and informing the UE to perform channel measurement for the subset of antenna ports that is required to be measured and feed back channel state information. Through the present invention, when the state information of the UE meets a certain condition, the UE measures only the reference signals of a part of antenna ports, and feeds back channel state information for this part of antenna ports. Therefore, the overhead generated by the feedback of the UE to the channel state information is reduced.

摘要： A method, an apparatus and a system for estimating channels are disclosed. A method for estimating channels includes: receiving, by a User Equipment (UE), downlink signals sent by two or more Access Points (APs), wherein no common reference signal is comprised in any data channel symbol domain except a preset symbol domain in the downlink signals; and performing, by the UE, channel estimation according to the downlink signals. The technical solution disclosed herein eliminates the interference between the reference signal and the data signal, enables the UE to estimate the channel value between the UE and the cooperative APs accurately, and improves the UE performance.
