Abstract: According to embodiments of the present disclosure, a solution for supporting repetitions for a plurality of downlink data transmission scheduled by signal downlink control information is proposed. A terminal device receives downlink control information (DCI) scheduling a plurality of downlink data transmissions with repetitions from a network device. The terminal device determines a hybrid automatic repeat request (HARQ)-ACK codebook for the plurality of downlink data transmissions based on a repetition pattern for the plurality of downlink data transmissions and the slot offset. The terminal device transmits a feedback for the repetitions for the downlink data transmissions based on the HARQ-ACK codebook to the network device. In this way, it achieves a flexible repetition patterns for the plurality of downlink data transmissions scheduled by signal DCI, which improves the coverage/reliability performance for data transmission.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media of communication. A transmitting device determines whether no DM-RS is to be transmitted on a first symbol configured for DM-RS transmission and if no DM-RS is to be transmitted on the first symbol, transmits a signal to a receiving device in at least part of REs on the first symbol, the signal comprising at least one of data or a PT-RS. The receiving device demodulates the signal from the at least part of REs on the first symbol. In this way, DM-RS overhead may be reduced and the interference to co-scheduled UE may be avoided.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. According to embodiments of the present disclosure, a terminal device transmits, to a network device, a channel state information (CSI) report indicating a correspondence between reported values of a plurality of groups of resources and a plurality of channel measurement resource sets configured by the network device. Each of the plurality of groups comprises resources selected from different channel measurement resource sets. In this way, the uplink control information may be used for indicating the CSI at the level of beam pairs with a suitable payload size.

Abstract: Embodiments of the present disclosure provide a solution for sidelink transmission. In a method for communication, a first terminal device determines a resource selection window for a sidelink transmission from the first terminal device to a second terminal device. Then, the first terminal device determines a duration within the resource selection window. Further, the first terminal device determines at least one resource for the sidelink transmission within the resource selection window without the duration. In this way, the resource selection window of the first terminal device for the sidelink transmission is optimized, thereby improving the performance of the sidelink transmission.

Abstract: Embodiments of the present disclosure provide a solution for sidelink communications. In a method for communications, a first terminal device determines from a resource pool configured for the first terminal device, first resources in a time window before a first slot based on a resource selection scheme of the first terminal device. The first terminal device determines a first number of occupied resources in the first resources. The first terminal device determines a congestion level indicator of a sidelink channel for the first slot based at least in part on the first number and a number of the first resources. The sidelink channel is associated with the first terminal device. With the proposed mechanism, the sidelink congestion level indicator, such as, a channel busy ratio (CBR) is determined with consideration of the resource selection scheme and the reception capability of the terminal device. As such, the accuracy of CBR measurement can be improved, which is beneficial to sidelink congestion control and a reduction of the power consumption at the terminal device.
