An operation method of a base station in a communication system includes transmitting, to a terminal, a radio resource control (RRC) message including transmission configuration information (TCI)-state configuration information including information indicating a starting beam index and an ending beam index and reference signal related information; transmitting, to the terminal, a first downlink control information (DCI) including a first TCI indicating the starting beam index and first resource allocation information; and transmitting, to the terminal, a first physical downlink shared channel (PDSCH) through a resource indicated by the first resource allocation information by using a starting beam indicated by the first TCI.
摘要:
When a device-to-device (D2D) terminal simultaneously receives control information from two or more different D2D terminals, the D2D terminal transmits control information of a first D2D terminal of at least one of the two or more D2D terminals to a second D2D terminal of at least the other one of the two or more D2D terminals.
摘要:
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.

An operation method of a terminal may comprise: receiving information on a common delay time between the terminal and the base station and information on a PRACH occasion through a service link established between the terminal and the satellite; calculating a first adjustment value based on the common delay time; transmitting a PRACH preamble through the service link at a first timing earlier by the first adjustment value than the PRACH occasion; receiving a random access response (RAR); calculating a second adjustment value based on the common delay time; and transmitting an uplink signal through the service link at a second timing later by the second adjustment value than the response delay time.
摘要:
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.
