Abstract: In a signal transmission method and apparatus, a network device sends scheduling information of at least one of two carriers whose communication directions are opposite on a target OFDM symbol; a terminal device performs channel transmission of a target carrier on the target OFDM symbol based on the scheduling information, where the target carrier is one of carriers that are of the two carriers whose communication directions are opposite and that have channel transmission on the target OFDM symbol; and the network device performs channel transmission on the target OFDM symbol and the target carrier. A time domain resource may be allocated to a carrier on which transmission scheduling is currently performed, thereby improving transmission resource utilization and reducing a waiting delay.

Abstract: A resource configuration method includes obtaining, by a relay node, first information, wherein the first information comprises an identifier of at least one beam useable for sending a first signal. The method further includes sending second information to a parent node based on the first information, wherein the second information comprises a correspondence between the at least one beam and a desired power spectrum density (PSD). The method further includes receiving third information from the parent node, wherein the third information is useable to indicate to the relay node to determine a transmit power based on the third information.

Abstract: In a guard symbol configuration method and a communication apparatus, a first node indicates, to a second node, a number of guard symbols used or expected to be used in a larger subcarrier spacing, to avoid a scheduling conflict. The method includes: the first node sends a first medium access control control element (MAC CE) to the second node, where the first MAC CE indicates a number of guard symbols used in a first subcarrier spacing. The first node sends a second MAC CE to the second node, where the first MAC CE and the second MAC CE are jointly used to determine a number of guard symbols used or expected to be used in a second subcarrier spacing.

Abstract: This application discloses a communication method and a communication apparatus. The method includes: A terminal device receives first indication information from a network device, where the first indication information indicates a first time interval. The first time interval is an interval between an end time point of a first signal and a start time point of a second signal. The terminal device receives or sends the second signal at least after the first time interval elapses after the first signal. The first signal and the second signal are sent in a same BWP. A first filter parameter corresponding to the first signal is different from a second filter parameter corresponding to the second signal. The first time interval is related to switching duration of the terminal device.

Abstract: Example resource dynamic indication methods and an apparatus are described. One example method includes determining, by a first node based on first indication information sent by a second node or a donor node, semi-static resource configuration on first resources corresponding to D carriers and second resources corresponding to F cells. The first node determines, based on second indication information sent by the second node or the donor node, an availability status of an available resource in the first resources corresponding to the D carriers and an availability status of a dynamic resource in the second resources corresponding to the F cells.

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: A terminal determines a validity duration of a first parameter and a validity duration of a second parameter. The first parameter includes positioning information of the terminal, and the second parameter includes one or more of the following information: ephemeris information of a serving satellite and common timing advance (TA) information. Then, the terminal determines an invalidation moment of the first parameter and an invalidation moment of the second parameter based on a validation moment of the first parameter, a validation moment of the second parameter, the validity duration of the first parameter, and the validity duration of the second parameter. The terminal updates the first parameter and the second parameter at or before an earlier invalidation moment in the invalidation moment of the first parameter and the invalidation moment of the second parameter. The terminal determines a TA adjustment value based on an updated first parameter and an updated second parameter.

Abstract: A communication method and apparatus. for indicating indicate A terminal is indicated to perform second transmission when an SSB or a PRACH on a frequency domain resource overlaps with reverse transmission on another frequency domain resource in time domain. In response to the SSB or the PRACH overlapping with the second transmission in time domain, the terminal device determines, by receiving first indication information, that a priority of the SSB or the PRACH is lower than a priority of the second transmission on an overlapped time domain resource. The terminal device performs the second transmission based on the first indication information. The terminal device performs reverse transmission on a symbol that overlaps with the SSB or the PRACH.
