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 relate to methods, devices and computer storage media for communication. A method comprises transmitting, from a network device to a terminal device, a set of repetitions of downlink control information (DCI) for scheduling data transmissions from the network device to the terminal device; performing, based on the set of repetitions of the DCI, the data transmissions from the network device to the terminal device; and receiving, from the terminal device, a single feedback signal for the data transmissions. Embodiments of the present disclosure can improve reliability and robustness for Physical Downlink Control Channel (PDCCH).

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A terminal device receives, from a network device, a first timing value set associated with a first HARQ feedback with a first priority, a second timing value set associated with a second HARQ feedback with a second priority different from the first priority, and a TDRA list for the first and second HARQ feedbacks, determines a third timing value set from the first and second timing value sets, constructs a HARQ codebook comprising the first and second HARQ feedbacks at least based on the third timing value set and the TDRA list, and transmits the HARQ codebook to the network device on an uplink control channel. In this way, unnecessary redundancy in HARQ bits can be removed and UCI overhead can be reduced.

Abstract: Embodiments of the present disclosure relate to methods for communication, terminal devices, network devices and computer readable media. In the method, a terminal device determines a transmission configuration indicator (TCI) state for a physical downlink control channel (PDCCH) candidate, based on at least one of: an index of the PDCCH candidate, and an index of a control channel element (CCE) of the PDCCH candidate. The terminal device monitors the PDCCH candidate based on the TCI state. As a result, the complexity of the terminal device for blind detection or decoding is able to be reduced.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable mediums for beam management. In example embodiments, a method implemented at a first network device is provided. According to the method, a first group of resources are determined to be used by a terminal device for determining a first group of beams from the first network device. The first group of resources are different from a second group of resources configured by a second network device to the terminal device for determining a second group of beams from the second network device. The first group of resources are configured to the terminal device. A plurality of synchronization and/or reference signals are transmitted, using the first group of beams, on the first group of resources to the terminal device.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer storage media for communication. A method comprises transmitting, from a network device to a terminal device, downlink control information for scheduling transmissions of data and channel state information (CSI) from the terminal device; receiving the data from the terminal device based on a first slot offset configured for uplink data transmission or a second slot offset configured for the CSI; and receiving the CSI from the terminal device based on the second slot offset. As such, in case of higher frequency band with larger subcarrier spacing, embodiments of the present disclosure can support uplink data scheduling and A-CSI report triggering with same DCI.
