Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of retransmission mechanism for configured grant uplink transmission. The method comprising transmitting, to a second device, a transport block while starting a configured grant retransmission timer for autonomous retransmission of the transport block; in response to receiving, from the second device, a feedback indicating unsuccessful reception of the transport block, adjusting expiry time of the configured grant retransmission timer without starting the autonomous retransmission of the transport block; determining whether scheduling information for retransmission of the transport block is received before the adjusted configured grant retransmission timer expires; and in response to determining that the scheduling information is received, retransmitting the transport block while stopping the configured grant retransmission timer. In this way, the retransmission in the Hybrid Automatic Repeat Request process could be performed according to the uplink grant scheduled by the network device and therefore the retransmission efficiency for configured grant uplink transmission in unlicensed spectrum can be improved.

Abstract: Example embodiments of the present disclosure relate to logical channel prioritization. A method includes obtaining an uplink grant from a network device, the uplink grant indicating uplink resources for transmission to the network device and selecting a logical channel prioritization setting from a plurality of logical channel prioritization settings based on a predetermined policy related to the uplink grant, the logical channel prioritization settings defining different sets of prioritization parameters for uplink data in at least one logical channel and uplink control information in occupying the uplink resources. The method further includes generating, based on the logical channel prioritization setting, a packet data unit including at least one of the uplink control information or at least one part of the uplink data for transmission to the network device using the uplink resources. In this way, adaptive and dynamic prioritization across logical channels can be achieved at the terminal device.

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.
