A terminal according to one aspect of the present disclosure includes a receiving section that, when different physical cell IDs are configured for a plurality of transmission/reception points (TRPs), receives information related to a downlink reference signal from a second TRP out of the plurality of TRPs by using higher layer signaling, and a control section that controls transmission of an uplink signal on the basis of the information. According to one aspect of the present disclosure, it is possible to perform appropriate communication when different physical cell IDs are configured for a plurality of TRPs.

A method for a user equipment (UE) operating in a non-terrestrial network (NTN) is provided. The method includes receiving, from a base station (BS), assistance information; starting or restarting a timer upon receiving the assistance information; applying the assistance information to perform uplink synchronization; and determining that the UE has lost the uplink synchronization upon expiration of the timer.

Technologies and techniques for wireless communication between a scheduled entity and a scheduling entity in a wireless communication network. A scheduled entity receives a downlink (DL) reference signal (RS) from the scheduling entity on a channel between the scheduling entity and the scheduled entity. The scheduled entity obtains channel state information (CSI) for the channel between the scheduling entity and the scheduled entity using the received DL RS, selects an uplink resource associated with a random-access procedure, and multiplexes a CSI report including the CSI with a random-access message related to the random-access procedure to produce multiplexed information.
