摘要： 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.

摘要： 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.

摘要： This application provides a communication method and a communication device. The method includes: A terminal device obtains an uplink timing advance TA of a serving cell. The terminal device obtains a downlink signal time difference between the serving cell and a neighboring cell. The terminal device obtains an uplink TA of the neighboring cell based on the uplink TA of the serving cell and the downlink signal time difference. The terminal device sends an uplink signal to the neighboring cell based on a downlink subframe timing and the uplink TA of the neighboring cell. The uplink TA of the neighboring cell is obtained, so that the terminal device can send the uplink signal to the neighboring cell based on the uplink TA of the neighboring cell.
