When a base station is capable of using multiple different types of waveforms for a downlink communication to a UE, the UE may waste processing resources attempting to receive and/or process the downlink communication. For example, the UE may cycle through various possible types of waveforms in an attempt to process the downlink communication. Techniques described herein use waveform signaling for downlink communications to notify the UE of a type of waveform being used for a downlink communication, thereby conserving UE resources (e.g., processing resources, memory resources, RF resources, and/or the like) that would otherwise be wasted attempting to process the downlink communication using multiple types of waveforms.

A method for determining channel quality indication (CQI) information, implemented by a base station, includes: determining whether intra-device interference occurrence situations of user equipment (UE) in a CQI measurement period and a subsequent downlink (DL) scheduling period of a bandwidth granularity are the same; and in response to the intra-device interference occurrence situations being different, determining a CQI level for subsequent DL scheduling in the bandwidth granularity based on a preset offset.

A terminal device for use in a wireless telecommunications system includes: a transceiver configured to perform wireless communication with a base station using a communications resource allocated to the terminal device by the base station; and a controller configured to: control the transceiver to receive a grant signal from the base station, the grant signal specifying a communications resource for use by the terminal device; control the transceiver to send a wireless message to the base station using the communications resource specified by the grant signal; determine, in dependence upon the grant signal, a subset, being some but not all, of a set of control data elements providing wireless signalling from the base station to the terminal device; and detect, from a control data element in the subset, acknowledgement information sent by the base station in respect of the wireless message.

A user device, UE, for a wireless communication system, is connected to one or more further UEs in the wireless communication system for a sidelink communication with the one or more further UEs. The sidelink communication include one or more sidelink control messages, e.g., a Sidelink Control Information, SCI, to be transmitted on sidelink resources. The UE identifies a sidelink control message for the UE by blind decoding, and decodes the sidelink control message for the UE to derive control information embedded the sidelink control message. The UE is pre-configured or configured by a network or a base-station with a sidelink, SL, search space, e.g., a SL-CORESET or SL control channel occasions, in the sidelink resources. The sidelink search space includes one or more search occasions where the UE is to perform the blind decoding on the sidelink resources.

According to one aspect of the present disclosure, SP-CSI report and/or detection can be appropriately controlled even when SP-CSI report activation is indicated by using MAC CEs (Medium Access Control Control Elements).
