Abstract: Example embodiments relate to communication of uplink control information. A method implemented at a terminal device comprises obtaining a plurality of uplink grants available for uplink transmission to a network device, the plurality of uplink grants indicating resources for the uplink transmission; determining prioritization of the plurality of uplink grants in transmission of uplink control information based on a predetermined prioritization policy; and selecting, based on the determined prioritization, an uplink grant from the plurality of uplink grants for transmission of the uplink control information to the network device. In such a way, it is possible to increase a probability of transmission of the uplink control information and/or a probability of improving power efficiency of the terminal device.

Abstract: Example embodiments of the present disclosure relate to channel information transmitting for dormant bandwidth part. According to embodiments, a solution for channel information transmitting for dormant bandwidth part has been proposed. A terminal device is configured a periodicity when an active downlink (DL) bandwidth part (BWP) is a dormant BWP. The periodicity is different from a further periodicity which is configured and used when the active DL BWP is a non-dormant BWP. The terminal device uses resourced configured for the active uplink (UL) BWP but with the different periodicity. In this way, it allows sounding reference signal (SRS)/channel state information (CSI) reporting without duplicating configurations of BWPs. It can configure a required longer periodicity but reduce the SRS configuration for each UL BWP.

Abstract: Example embodiments of the present disclosure relate to reporting beam failure. A terminal device performs beam failure detection on a first number of serving cells configured for the terminal device. The terminal device determines information to at least indicate respective results of the beam failure detection on a second number of serving cells among the first number of serving cells, where the second number is smaller than the first number. The determined information is transmitted by the terminal device to a network device serving the terminal device using a resource allocated for the terminal device. Based on the information, the network device determines an overall result of the beam failure detection performed on the first number of serving cells.

Abstract: Embodiments of the present disclosure relate to mechanism for interactions for entering into the sleep mode. According to embodiments of the present disclosure, the network device transmits the information of go-to-sleep, GTS, to the terminal device on a lower layer (for example, the physical layer). The lower protocol layer informs the higher protocol layer (for example, the MAC layer) of the information of GTS. The terminal device determines how to monitor the physical downlink channel based on the information of GTS. Further, the terminal device may switch bandwidth part based on the information of GTS. In this way, the GTS is able to significantly save power.

Abstract: Embodiments of the present disclosure relate to a device, a method, an apparatus and a computer readable storage medium for bandwidth part (BWP) switching. In example embodiments, a method is provided. The method comprises determining, at a terminal device, whether continuous Listen-Before-Talk (LBT) failures occur on a first bandwidth part (BWP), the terminal device operating on the first BWP. The method further comprises in response to the continuous LBT failures occurring on the first BWP, switching to a second BWP different from the first BWP. Instead of triggering a re-establishment procedure once continuous LBT failures are detected, switching to another BWP on different LBT sub-channels can be much more efficient than going through the whole re-establishment and reconfiguration procedures.
