摘要： 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.

摘要： Embodiments of the present disclosure relate to communication. According to embodiments of the present disclosure, a sub-slot based hybrid automatic repeat request acknowledgment codebook determination for semi-persistent scheduling (SPS) release is achieved. The terminal device receives an indication to release SPS. The terminal device determines a position to transmit a feedback to the indication in an uplink channel or determined to drop the feedback. The network device is able to obtain the feedback associated with the SPS release. In this way, the feedback can be transmitted properly.

摘要： Example embodiments of the present disclosure relate to an effective mechanism for handing the scenario of discontinuous coverage. In this solution, the terminal device generates at least one beam report based on an active transmission configuration indicator (TCI) state of the terminal device, where the terminal device is configured with at least one of a serving cell associated with a first physical cell identity (PCI) and a neighbor cell associated with a second PCI. The terminal device further transmits the at least one beam measurement report in the serving cell or in the neighbor cell. In this way, the number of reporting the useless and unnecessary measurements result is reduced.

摘要： Embodiments of the present disclosure relate to methods, devices and computer readable media for communications. A method implemented at a terminal device comprises in response to switching to a second frequency part, determining a time duration for the terminal device to use a first reference signal received from a network device in a first frequency part as a Quasi Co-location (QCL) reference signal. The terminal device performs communication with the network device before the time duration ends based on a first set of properties obtained by measuring at least the first reference signal. The method also comprises obtaining, within the time duration, a second set of properties by measuring at least a second reference signal received from the network device in the second frequency part, the second reference signal and the first reference signal having a first identification. The method also comprises performing, after the time duration, communication in the second frequency part with the network device based on the second set of properties by using the second reference signal as the QCL reference signal.

摘要： Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A first device receives, from a second device, a configuration regarding a periodicity of resource allocation. The first device determines a set of occasions based on the configuration, gaps between adjacent occasions in the set of occasions being non-uniform. If a set of data transmissions are to be performed, the first device performs the set of data transmissions on at least part of the set of occasions. In this way, a SPS or CG occasion may be roughly aligned with arrival time of a packet without accumulated latency, wasted resource and additional signaling overhead.

摘要： Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A terminal device receives, from a network device, first DCI scheduling a first set of data transmissions and second DCI scheduling a second set of data transmissions. If the first set of data transmissions on a first set of scheduled resources and the second set of data transmissions on a second set of scheduled resources are to be performed, the terminal device determines a first reference transmission from the first set of data transmissions and a second reference transmission from the second set of data transmissions to follow an in-order scheduling, the second set of scheduled resources being in a set of gaps among the first set of scheduled resources in time domain. In this way, an in-order scheduling or HARQ transmission restriction is obeyed.

摘要： Embodiments of the present disclosure relate to methods, devices and computer storage media for communication. A terminal device receives a configuration concerning random resource selection. The terminal device transmits, to a network device, information related to a target TCI state in a first set of TCI states for transmission between the terminal device and the network device. The first set of TCI states is at least partially non-overlapping with a second set of TCI states which have been activated. The target TCI state is outside the second set of TCI states. After that, the terminal device sets at least the target TCI state in the first set of TCI states as activated. As a result, MAC CE activation will not be required. Thus, signaling overhead and latency will be reduced.

摘要： 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.
