Abstract: Example uplink channel listening methods and apparatus are described. In one example method, a contention window size (CWS) is determined with reference to a time threshold, for example, a timer. After sending an uplink burst, if a terminal device does not receive indication information carrying a hybrid automatic repeat request (HARQ) status, the terminal device increases the CWS and then performs channel listening.

Abstract: Method for receiving retransmitted data is disclosed. A terminal device receives identification information of a code block group. The code block group is one of a plurality of code block groups of a transport block that the terminal device received from a radio access network device, and the code block group includes at least one code block that is not transmitted correctly. The terminal device also receives a retransmission of the code block group from the radio access network device. The terminal device restores information carried in the received transport block. The identification information of the code block group is carried in downlink control information. The identification information of the code block group indicates which code block group of the transport block is retransmitted. The downlink control information further includes indication information that indicates whether the code block group is punctured or interfered.

Abstract: A response information transmission method and an apparatus are provided. After receiving first downlink data from a network device, a terminal device transmits the first downlink data in a semi-persistent scheduling manner, and determines, based on a transmission status of first response information of the first downlink data, whether to send the first response information to the network device. The transmission status may include two states: One state represents that the first response information and first uplink information are to be simultaneously transmitted in a first time unit, and the other state represents that the first response information is to be separately transmitted in the first time unit. When the first response information is to be separately transmitted in the first time unit, the network device determines, based on the transmission status of the first response information, whether to receive the first response information.

Abstract: Embodiments of the present invention disclose a communication method and apparatus. The method includes: After receiving, from a network device, information about K uplink data channels for repeating a data packet for K times and information about a first time domain resource for transmitting first uplink control information UCI, in a case in which the first time domain resource overlaps a first uplink data channel of the K uplink data channels in time domain and the first uplink data channel is overloaded, a terminal device determines a physical resource for transmitting the first UCI, and then sends the first UCI to the network device by using the determined physical resource.

Abstract: This application provides a method for multiplexing uplink control information, and relates to the wireless communications field. When a resource of a first uplink control channel that carries first HARQ-ACK information does not overlap a resource of a second uplink control channel that carries second HARQ-ACK information in time domain, but a resource of a third uplink control channel that carries an SR/CSI overlaps both the resource of the first uplink control channel and the resource of the second uplink control channel in time domain, a base station and UE determine, based on a format of the first uplink control channel, a format of the second uplink control channel, and a format of the third uplink control channel, that third HARQ-ACK information and first UCI are multiplexed for transmission, where the third HARQ-ACK information is the first HARQ-ACK information or the second HARQ-ACK information.

Abstract: This application relates to the field of communication technologies, and discloses a transport block size determining method and an apparatus. The method includes: A terminal device determines, based on control information sent by a network device, K transmission occasions used to transmit a first data packet, where at least two of the K transmission occasions include different quantities of valid REs. Further, the terminal device may determine, based on a target quantity of valid REs, a TBS corresponding to the first data packet, where the target quantity of valid REs may be an average quantity of valid REs of the K transmission occasions, or may be a quantity of valid REs included in a target transmission occasion in the K transmission occasions.

Abstract: In a control information receiving method, a second device receives m control channels from a first device. Control information carried on the m control channels corresponds to a same hybrid automatic repeat request (HARQ) process and is consecutive control information of the HARQ process, control information carried on each of the m control channels includes false alarm indication information, and m is a positive integer greater than or equal to 2. The second device determines, based on a combined state of false alarm indication information carried on the m control channels, whether there is a false alarm in control information carried on at least one of the m control channels.
