摘要： A method and apparatus for reporting channel state information (CSI) based on a physical uplink shared channel (PUSCH) are used to realize correct reporting of the CSI based on double code books. The method includes the following steps: a reporting mode configuration signaling for the CSI sent from a network side is received, and said reporting mode configuration signaling for the CSI at least carries a designated reporting mode identifier; a first CSI aiming at the whole bandwidth of a system is established according to a reporting type corresponding to said reporting mode identifier; the whole bandwidth of the system is divided into at least two frequency band subclasses, and a second CSI aiming at a designated frequency band subclass is established according to the reporting type corresponding to said reporting mode identifier; and when a reporting indication signaling sent from the network side is received, said first CSI and said second CSI are transmitted to the network side. Therefore, when a user equipment (UE) reports the CSI, a long-term/wideband CSI and a short-term/frequency selective CSI could be considered comprehensively, then a two-level feedback mechanism based on the PUSCH double code books is realized.

摘要： A method and device for reporting antenna calibration information and determining antenna calibration factor are provided by the present invention. When reporting the antenna calibration information, a user equipment (UE) estimates the downlink equivalent baseband channel from a plurality of antennas of the base station to the UE; according to the equivalent baseband channel, determines the amplitude response and delay value to be reported, and then reports the amplitude response and delay value to the base station. When determining the antenna calibration factor, according to the uplink signal sent by the UE on the base station-directed time-frequency resources, the base station determines the amplitude response and the delay value; according to the amplitude response and delay value reported by the UE and according to the amplitude response and delay value determined by the uplink signal, the base station calculates the antenna calibration factor. Because the UE pre-processing process is added, the sensitivity degrees to the channel estimation error and to the channel Doppler extension are reduced.
