Abstract: Embodiments of this application provide a method for processing information bits in a wireless communication network. A communication device receives a radio resource control (RRC) signaling, wherein the RRC signaling comprises time window information and time unit format information, wherein the time window information comprises a hybrid automatic repeat request (HARQ) time sequence K1 set, wherein K1 is a time relationship between a time unit of a physical downlink shared channel (PDSCH) and a time unit of a physical uplink control channel (PUCCH), or wherein the K1 is a time relationship between a time unit of a (PDSCH) and a time unit of a physical uplink shared channel (PUSCH). The device determines HARQ feedback information based on the time window information and the time unit format information and sends the HARQ feedback information.

Abstract: A method for determining time information is disclosed. The method includes: obtaining, by a network node, information sent by a terminal device; and determining, by the network node, at least one of the following based on the information: a first time interval between downlink scheduling and downlink data transmission, a second time interval between the downlink data transmission and a feedback message sent by the terminal device after the terminal device receives downlink data, and a third time interval between uplink scheduling and uplink data transmission, where the information may include at least one of a subcarrier spacing, an operating band, and a bandwidth that are supported by the terminal device, and further include a first smallest value and/or a second smallest value and/or a third smallest value corresponding to the at least one item. Therefore, flexibility and accuracy of determining the time information are improved.

Abstract: The disclosure relates to a network node and a user device. The network node is configured to determine a resource indicator comprising a single resource allocation value that specifies a first start index and a first number of frequency resources. The first start index and the first number of frequency resources are used for allocating a first set of contiguous frequency resources within a first sub-band, and a corresponding first set of contiguous frequency resources within a second sub-band. The first sub-band and the second sub-band are non-overlapping and comprise equal number of frequency resources. The network node includes a transceiver configured to transmit a transmission grant comprising the resource indicator to the user device.

Abstract: This application provides methods and apparatuses for sending a HARQ-ACK feedback codebook. One example method includes detecting DCI in a plurality of time units corresponding to at least one carrier, where a type of the DCI is a first DCI type or a second DCI type, where the first DCI is used to indicate to feed back CBG-level HARQ-ACK information for data scheduled by the first DCI, and where the second DCI is used to indicate to feed back TB-level HARQ-ACK information for data scheduled by the second DCI. A HARQ-ACK feedback codebook is then sent to a network device, where the codebook includes HARQ-ACK information of at least one piece of data scheduled by the DCI, and the HARQ-ACK feedback codebook is determined according to the type of the DCI and a type of the HARQ-ACK feedback codebook.

Abstract: Various embodiments provide a signal transmission method and apparatus, and is applied to a multi-band communications system. Under the method, a terminal reports bandwidth capability information of a first frequency band in a plurality of frequency bands to a radio access network node. An operating band of the terminal includes the first frequency band, the bandwidth capability information of the first frequency band indicates a bandwidth capability of the terminal in the first frequency band, the bandwidth capability in the first frequency band is not less than a first threshold, and the first threshold is determined based on a maximum bandwidth capability of the terminal, the first frequency band, or a subcarrier spacing of the first frequency band. The terminal can send or receive a signal on a resource allocated by the radio access network node based on the bandwidth capability information.

Abstract: Examples communication methods and communications apparatus are described. In one example method, a base station sends a first synchronization signal block, where the first synchronization signal (SS) block includes a primary SS, a secondary SS, and information carried on a physical broadcast channel (PBCH). In addition, the base station sends a second SS block, where the second SS block includes a primary SS or includes a primary SS and a secondary SS, and does not include information carried on the PBCH. The first SS block is used by a terminal to access the base station. The second SS block is used to perform time and frequency synchronization after the terminal accesses the base station.
