Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A network device generates downlink control information scheduling multiple data channels grouped into a plurality of groups, and transmits the downlink control information to a terminal device. Upon receipt of the downlink control information, the terminal device performs data transmission between the terminal device and the network device based on the grouped data channels. In this way, a payload of the downlink control information can be reduced and false detection rate can also be reduced.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication of a RS. According to embodiments of the present disclosure, the terminal device receives information indicating a set of resources for transmitting a reference signal from the network device. If the terminal device receives an indication in a reference signal trigger slot for triggering a transmission of the reference signal, the terminal device determines a slot for transmitting the reference signal. The terminal device determines whether the slot is valid based on a slot configuration. In this way, it can avoid the SRS transmission timing ambiguous or misalignment between UE and network.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer storage media for communication. According to embodiments of the present disclosure, a first physical downlink control channel (PDCCH) indicating a transmission configuration indication (TCI) state is transmitted from a network device to a terminal device. The terminal device applies, based on a first time threshold, the TCI state for monitoring a second PDCCH transmitted from the network device. The terminal device applies, based on a second time threshold, the TCI state for receiving a physical downlink shared channel (PDSCH) transmitted from the network device. As such, a common beam used for PDCCH and PDSCH, which is indicated by a common TCI state, can be updated and the updated beam can be applied for PDCCH and PDSCH transmission/reception.
