Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for PUSCH repetition. According to embodiments of the present disclosure, the terminal device determines a set of physical uplink shared channel, PUSCH, repetition occasion slots based on a first omission rule. Then, the terminal device determines, from the set of PUSCH repetition occasion slots, PUSCH repetition actual slots based on a second omission rule. And then, the terminal device transmits data in the determined PUSCH repetition actual slots. In this way, an enhanced PUSCH enhancement solution is provided, thereby improving coverage of the network and increasing robustness of the uplink transmission.

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 receives configuration information from a network device. The configuration information at least indicates a set of configurations for transmitting a demodulation reference signal (DMRS). The terminal device receives downlink information from the network device which indicates an adaptive DMRS configuration. The terminal device transmits the DMRS to the network device based on the adaptive DMRS configuration. In this way, the configuration of reference signals can be changed dynamically.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication on unlicensed band. In example embodiments, a method includes determining, at a terminal device, a time interval preceding a start symbol for uplink transmission. The method further includes determining, based on a first signal generating operation for the start symbol, a second signal generating operation for the time interval. The method further includes transmitting, to a network device over the time interval, a signal generated based on the second signal generating operation.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A terminal device receives, from a first network device, a conditional reconfiguration indicating that a subsequent conditional cell change is enabled. If the subsequent conditional cell change to a candidate cell is to be performed after a cell change or addition is performed, the terminal device determines a first counter value, the first counter value being different from a second counter value used for the cell change or addition, and determines, based on the first counter value, a security key for communication with a second network device providing the candidate cell. In this way, a security key is determined for a subsequent conditional cell change.

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 receives, from a network device, a configuration indicating a configured grant (CG) physical uplink shared channel (PUSCH) resource and a search space which is specific to the terminal device. The terminal device transmits, to the network device, data using the CG PUSCH resource. The terminal device monitors a physical downlink control channel (PDCCH) on the search space using a reference signal which is quasi-collocated (QCL) with a beam on which the data is transmitted using the CG PUSCH resource. In this way, it can achieve better link performances.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A method of communication comprises receiving, at a terminal device, a configuration of a scheduling gap from a first network device, the scheduling gap being configured for a portion of serving cells of the first network device; and switching, based on the configuration of the scheduling gap, to a second network device while maintaining a radio resource control connection with the first network device. Thereby, a scheduling gap with a smaller granularity can be configured and used, and thus an interruption of a service at the first network device can be avoided as much as possible.
