    Abstract: A method and an apparatus for allocating ACKnowledgement (ACK)/Non-ACKnowledgement (NACK) channel resources and processing confirmation information are disclosed. The method includes: The network side determines one physical channel area among multiple physical channel areas to be used by an ACK/NACK channel, and notifies the determined physical channel area to a User Equipment (UE) so as to enable the UE to determine a channel for receiving or sending ACK/NACK information in the determined physical channel area according to a mapping rule. Moreover, the network side may send or receive ACK/NACK information on the physical channel area that includes the ACK/NACK channel. The method and apparatus improve the utilization ratio and flexibility of the ACK/NACK channel, and reduce the probability of conflict generated by the ACK/NACK channel.

    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: Example methods and apparatus for transmitting uplink control information are described. One example method includes receiving downlink control information by a terminal device, where the downlink control information includes resource information of a data channel, first indication information, and second indication information. The first indication information indicates a power offset value between a transmission time interval k and a transmission time interval k−1, and the second indication information is used to determine a power adjustment value in the transmission time interval k. The terminal device determines transmit power in the transmission time interval k based on the power offset value and the power adjustment value. The terminal device transmits uplink control information based on the transmit power, where the uplink control information includes feedback information for the data channel.

    Abstract: Embodiments provide a uplink channel transmission method. Scheduling information from the network device can be received by a terminal device. The scheduling information indicates uplink time-frequency resources carrying at least one uplink channel. a first uplink channel is carried on a first uplink time-frequency resource, and the first uplink time-frequency resource occupies M subbands in the N subbands in frequency domain, M≥2. The M subbands can be detected by the terminal device to determine, from the first uplink time-frequency resource, a second uplink time-frequency resource usable by the terminal device. The second uplink time-frequency resource occupies K subbands in the M subbands in frequency domain, and M>K≥1. The first uplink channel can be sent by the terminal device by using the second uplink time-frequency resource.

    Abstract: Embodiments of this application provide a method and a device for transmitting and receiving information. The method includes: receiving, by a terminal device on a first downlink carrier, a broadcast message transmitted by a network device, where the broadcast message includes second downlink configuration information corresponding to a second downlink carrier, the second downlink configuration information includes second downlink frequency information and/or physical cell identifier information of the second downlink carrier, the first downlink carrier and a second uplink carrier are serving carriers of the terminal device, the second downlink carrier is not a serving carrier of the terminal device, and the second downlink carrier and the second uplink carrier are paired carriers on a system level. Signal transmission on an LTE low-frequency uplink carrier based on LTE low-frequency downlink carrier configuration information carried on an NR high-frequency downlink carrier helps improve system performance in an NR-LTE coexistence scenario.
