Description

Method and apparatus for receiving and transmitting information Technical Field The present application relates to the field of wireless communication technology, and more particularly, to methods and apparatus for receiving and transmitting information. Background In order to meet the increasing demand for wireless data communication services since the deployment of 4G communication systems, efforts have been made to develop improved 5G or quasi 5G communication systems. Therefore, a 5G or quasi 5G communication system is also referred to as a "super 4G network" or a "LTE-after-system". The 5G communication system is implemented in a higher frequency (millimeter wave) band, for example, a 60GHz band, to achieve a higher data rate. In order to reduce propagation loss of radio waves and increase transmission distance, beamforming, massive Multiple Input Multiple Output (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, massive antenna techniques are discussed in 5G communication systems. Further, in the 5G communication system, development of system network improvement is being performed based on advanced small cells, cloud Radio Access Networks (RANs), ultra dense networks, device-to-device (D2D) communication, wireless backhaul, mobile networks, cooperative communication, cooperative multipoint (CoMP), receiving-end interference cancellation, and the like. In 5G systems, hybrid FSK and QAM modulation (FQAM) and Sliding Window Superposition Coding (SWSC) as Advanced Coding Modulation (ACM), and Filter Bank Multicarrier (FBMC), non-orthogonal multiple access (NOMA) and Sparse Code Multiple Access (SCMA) as advanced access technologies have been developed. The transmission from the base station to the User Equipment (UE) is referred to as downlink and the transmission from the UE to the base station is referred to as uplink. Disclosure of Invention In order to enhance the scheduling efficiency of the 5G wireless communication system, the base station needs to perform scheduling by acquiring Channel State Information (CSI) so as to correspondingly depend on CSI fed back by the terminal device. However, how to further enhance the performance related to CSI reporting is a problem to be solved. An aspect of the present disclosure provides a method performed by a User Equipment (UE) in a wireless communication system, the method including receiving a Channel State Information (CSI) reporting configuration, wherein the CSI reporting configuration relates to a resource set for channel measurement, reporting X first CSI reports, wherein CSI in the first CSI reports is used for reasoning and/or prediction, X is greater than or equal to 1, and reporting a second CSI report, wherein the CSI in the second CSI report is determined based on a comparison of a resource associated with a resource indicator included in each of the X first CSI reports and a resource determined based on measurement of the resource set for channel measurement. In an example, the CSI reporting configuration indicates a number N1 of reported resources, each CSI report of the X first CSI reports includes N1 resource indicators, and wherein the CSI in the second CSI report is determined based on a comparison of the resources associated with the N1 resource indicators in the X-th CSI report of the X first CSI reports with the resources determined based on the measurement of the set of resources for channel measurement, wherein X is any integer value between 1 and X. In an example, the comparing includes determining whether a resource with a highest measured layer 1-reference signal received power, L1-RSRP, of the set of resources for channel measurements determined based on the measurement of the set of resources for channel measurements is one of N1 resource indicator-associated resources in the xth CSI report. In an example, the N1 resource indicator associated resources include a resource associated with each of the N1 resource indicators or a resource associated with one of the N1 resource indicators. In an example, the comparing includes determining whether a resource associated with one of the N1 resource indicators in the xth CSI report is one of the highest L1-RSRP resources of the N2 measurements in the set of resources for channel measurements determined based on the measurement of the set of resources for channel measurements, N2 being greater than or equal to 1, where N2 is indicated by the CSI report configuration. In an example, the comparing includes determining whether a difference between a measured L1-RSRP of a resource associated with one of the N1 resource indicators in the xth CSI report and a highest measured L1-RSRP determined based on the measurement of the set of resources for channel measurements is less than a threshold, wherein the threshold is a predefined value, or the threshold is base station indicated, or the threshold is determined based on UE capability. In an example, one of the N1 resource
