Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of the enhancement on the UE report. The method comprises generating, a report including information related to a measurement relaxation performed by the first device based on a measurement relaxation configuration, the report being associated with at least one of a RLF report or a successful handover report; and transmitting the report to the second device. In this way, the network can be aware about whether a failure was experienced in conjunction with the measurements relaxation. With the enhanced report, the network may determine the future configuration of the measurement relaxation.

Abstract: According to embodiments of the present disclosure, when an unknown secondary cell configured with a physical uplink control channel is activated, a terminal device determines whether to transmit beam information to a network. The terminal device receives a physical downlink control channel (PDCCH) order in a beam which is selected in association with the beam information. In this way, a proper beam can be determined to transmit PDCCH order and it can also reduce delay.

Abstract: Embodiments of the present disclosure relate to a method, device and computer readable storage medium of communication. The method implemented at a first device includes receiving, at a first device and from a second device, a measurement configuration to be performed by the first device, the measurement configuration including at least the following: first measurement occasions configured for the first device for receiving a reference signal, and information about a synchronization signal associated with the reference signal, the synchronization signal to be measured at second measurement occasions. The method also includes measuring the reference signal at one or more of the first measurement occasions. The method further includes skipping measuring the synchronization signal at one or more of the second measurement occasions.

Abstract: Embodiments of the present disclosure relate to a method, device and computer readable storage medium of communication. The method implemented at a first device comprises determining, at the first device, first timing of a channel state information reference signal from a target cell. The first device is configured by a second device to measure the channel state information reference signal. The method comprises determining second timing used by the first device to measure the channel state information reference signal. The method further comprises determining a timing difference between the second timing and the first timing. The method further comprises transmitting, to the second device and based on the timing difference, information concerning measurement of the channel state information reference signal.

Abstract: Disclosed are devices, methods, apparatuses, and computer readable media for synchronization signal block measurement. An example apparatus for a terminal device may include at least one processor and at least one memory. The at least one memory may store instructions that, when executed by the at least one processor, may cause the terminal device at least to: receive, from a network device serving the terminal device, a configuration for discontinuous transmission defining an active period and a non-active period of a cell associated with the network device; determine whether to perform a synchronization signal block measurement during the non-active period based on a first condition and a second condition different from the first condition; based on said determining, if the first condition is satisfied, perform the synchronization signal block measurement during the non-active period; and based on said determining, if the second condition is satisfied, refrain from performing the synchronization signal block measurement during the non-active period.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of mitigation of performance degradation for improved system performance. The method comprises determining receive timing difference between a serving cell of the first device and a target cell, the serving cell being located on a first carrier, the target cell being located in a second carrier; and determining to report an indication associated with the receive timing difference to the second device. In this way, the network may be aware of experience performance degradation of the UE due to a large RTD without increasing the network complexity. Meanwhile, the TP performance of the UE may be improved.

Abstract: The present disclosure relates to a first cell activation when the cell discontinuous transmission (DTX)/discontinuous reception (DRX) is applied. In particular, a network device transmits a configuration of cell DTX and/or a configuration of cell DRX for a first cell to a terminal device. The network device also transmits an activation indication for the first cell. The terminal device monitors a set of reference signals from the network device during an activation procedure of the first cell. The terminal device further transmits a report that is based on a measurement on the set of reference signals to a cell that is a special cell or a physical uplink control channel cell. In this way, it can reduce the latency of the activation of the first cell.
