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 storage media for communication. According to embodiments of the present disclosure, a terminal device transmits, to a network device, a first hybrid automatic repeat request acknowledgement (HARQ-ACK) information corresponding to a first downlink control information (DCI) in a first physical downlink control channel (PDCCH), wherein the first DCI indicates a first transmission configuration indicator (TCI) state. If a condition is fulfilled, the terminal device applies the first TCI state. In this way, the terminal device understands when and/or whether to apply the indicated TCI state.

Abstract: Embodiments of the present disclosure relate to methods, devices, and computer readable medium for communication. According to embodiments of the present disclosure, a terminal device receives downlink information for triggering a report from a network device. The terminal device determines whether an inference failure occurs in a data processing model. The terminal device transmits the report to the network device. The report indicates whether the inference failure occurs in the data processing model and/or whether information in the report is generated based on the data processing model. In this way, the network device can be informed about the inference failure, thereby improving accuracy of information transmitted by the terminal device.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer storage media for communication. According to this solution, a terminal device detects a beam failure on a first component carrier (CC). The terminal device applies at least one ne quasi co-location (QCL) parameters as the ones associated with a first reference signal for downlink reception on the first CC until a first timing, or applies a spatial domain filter as the one associated with the first reference signal or as for a physical random access channel (PRACH) transmission for uplink transmission on the first CC until the first timing. In this way, the failed CC can still be under control of common beam update/activation.

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 configuration for a set of UL resources, and determines a time window for the set of UL resources. The time window is associated with a DRX cycle. An UL resource within the time window in the set of UL resources is used for an UL transmission and an UL resource outside the time window in the set of UL resources is invalid for transmission. The uplink transmission comprises at least one of a scheduling request, a buffer status report, or a configured grant uplink transmission. In this way, an UL resource may be determined based on a time window associated with a DRX cycle, and a UL triggered DRX may be achieved. Thus, an alignment between DL and UL transmissions may be facilitated and power saving may be improved.

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.
