Abstract: A transmitting device and a receiving device are described for a wireless communication system. The transmitting device transmits one or more synchronization signals on a carrier to at least one receiving device. A frequency of a synchronization signal among the one or more synchronization signals is located on a first frequency raster, and a carrier frequency of the carrier is deployed on a second frequency raster. The frequencies of two different synchronization signals among the one or more synchronization signals are located on different frequency positions in the first raster. The transmitting device transmits an indication of the carrier frequency to the at least one receiving device. The indication comprises at least one integer number. The receiving device derives the carrier frequency based on the at least one integer number.

Abstract: This application provides a method to improve resource utilization efficiency of an uplink control channel that carries feedback information. A terminal device receives one or more downlink channels carried in one or more first time units, the first time units belonging to in a time unit set; determines a second time unit for carrying feedback information corresponding to the downlink channels according to a first association relationship between the time unit set and the second time unit; determines a first codebook; and sends uplink control information including the first codebook in the second time unit. When one of the downlink channels is received in first time units that belong to a subset of the time unit set, and there is a second association relationship between the subset of the time unit set and the second time unit, the first codebook includes only feedback information corresponding to the downlink channel carried in the first time units in the subset.

Abstract: This application discloses communication methods and communication apparatuses. A terminal device receives indication information from a network device. The indication information includes one or more indication parameters. The terminal device obtains one or more pieces of configuration information based on the indication parameters. The terminal device performs uplink or downlink data transmission according to the one or more pieces of configuration information. Each pieces of configuration information includes information of a starting location and information of a quantity of time domain symbols in a slot that are occupied by uplink data or downlink data. Each piece of configuration information is selected from a first set of configuration information or a second set of configuration information. The first set of configuration information corresponds to a first mapping type of a physical downlink shared channel (PDSCH) and the second set of configuration information corresponds to a second mapping type of the PDSCH.

Abstract: Embodiments in this application relate to method and apparatus for transmitting downlink control information. A network device determines downlink control information, where the downlink control information includes at least one information field. The network device sends the downlink control information to a terminal device in a common search space or a common control resource set, or sends the downlink control information to the terminal device in a specific search space or a specific control resource set. The terminal device receives the downlink control information, and determines information indicated by the at least one information field of the downlink control information. According to the solutions provided in the embodiments of this application, requirements of various communication scenarios can be better satisfied.

Abstract: Embodiments of this application disclose a resource configuration method and a communication apparatus. The resource configuration method includes: An integrated access and backhaul mobile terminal (IAB MT) determines a first time division duplex (TDD) configuration based on a first transmission mode. The first transmission mode includes a transmission mode on at least one frequency domain resource set in a plurality of frequency domain resource sets of an integrated access and backhaul distributed unit (IAB DU). The first TDD configuration is a cell-common TDD configuration or a dedicated TDD configuration. The IAB MT determines a resource location based on the first TDD configuration. It can be learned from the technical solution that the IAB MT selects the corresponding TDD configuration based on the transmission mode on the at least one frequency domain resource set, to determine the resource location.

Abstract: A communication method, and related apparatuses are disclosed, to provide an MCS corresponding to a lower code rate, so as to better adapt to a requirement of a URLLC service. The communication method includes: determining N MCS indexes in an MCS table, where a value that is obtained by multiplying a code rate by 1024 and that corresponds to an MCS index X in the N MCS indexes is less than or equal to a first threshold, where X is an integer greater than or equal to 0, N is a positive integer, and N is greater than or equal to X; and sending at least one of the N MCS indexes.
