Abstract: Disclosed are methods for transmitting and receiving beamforming-based signals in a communication system. An operation method of a terminal may comprise transmitting capability information of the terminal to an AN; receiving first configuration information of a network cluster configured based on the capability information from the AN; transmitting an SRS in a beamforming scheme through resources indicated by the first configuration information; receiving second configuration information of a user cluster configured based on a measurement result of the SRS from the AN; and performing cooperative communication with ANs belonging to the user cluster, which are indicated by the second configuration information. Accordingly, the performance of the communication system can be improved.

Abstract: A hybrid beamforming based cooperative transmission system may comprise comprising a centralized processor (CP), access nodes (ANs) connected to the CP, and fronthaul links connecting the CP to the ANs. The CP may provide an outer precoding matrix for a first AN of the ANs, which is derived from global statistical channel state information (CSI) generated from local statistical CSI collected from the ANs, to the first AN via the fronthaul link; and the first AN may configure a radio frequency (RF) precoder of the first AN based on the outer precoding matrix, and configure a digital precoder of the first AN based on local instantaneous effective CSI between the first AN and first terminals to be served by the first AN.

Abstract: An operation method of a terminal in a communication system may comprise receiving a downlink data channel from a base station in a slot # n or a slot # (n−l); receiving a slot format indicator (SFI) indicating a format of a slot # (n+k) in which an uplink control information (UCI) is to be transmitted, from the base station in the slot # n; and transmitting the UCI including a hybrid automatic repeat request (HARQ) response for the downlink data channel to the base station in the slot # (n+k). Here, each of n and k may be an integer equal to or greater than 0, and l may be an integer equal to or greater than 1.

Abstract: Disclosed is a method for configuring a bandwidth for supporting a broadband carrier in a communication system. An operation method of a base station comprises the steps of: configuring a first bandwidth part and a second bandwidth part for a terminal; configuring a reserved resource for the first bandwidth part in a resource area in which the first bandwidth part and the second bandwidth part overlap; and performing an operation of transmitting or receiving a second data channel, which is scheduled to the second bandwidth part, together with the terminal by using the reserved resource. Therefore, the performance of the communication system can be improved.

Abstract: A method for receiving a PDCCH by a terminal in a mobile communication system may comprise the steps of: receiving a first PDCCH including first DCI from a base station through a first PDCCH search space; and receiving a second PDCCH including second DCI from the base station through a second PDCCH search space, wherein the first DCI and second DCI are for scheduling the same PDSCH for the same TB or TBs associated with the same HARQ process, are for scheduling different PDSCHs for the same TB or TBs associated with the same HARQ process, or are for scheduling different PDSCHs for different TBs or TBs associated with different HARQ processes. In addition, the first DCI and second DCI may be received from the base station within a time window.
