Abstract
A data transmission method and apparatus, and a communication device are provided. The data transmission method is performed by a first communication device, including: generating a desired guard symbol medium access control layer control element (MAC CE) when a preset trigger condition is met; and sending the desired guard symbol MAC CE to a second communication device.
Claims20
A data transmission method, performed by a first communication device, comprising:
- generating a desired guard symbol medium access control layer control element (MAC CE) when a preset trigger condition is met;
- and
- sending the desired guard symbol MAC CE to a second communication device,
- wherein both the first communication device and the second communication device are integrated access backhaul (IAB) nodes,
- wherein the generating the desired guard symbol MAC CE when the preset trigger condition is met comprises:
- the generating, when a first cell of an IAB node is configured or activated, the first cell is located in a third frequency band, and before the first cell is configured or activated, no cell is configured or activated in the third frequency band, the desired guard symbol MAC CE corresponding to the first cell by the IAB node.
A communication device, wherein the communication device is a first communication device, comprising:
- a memory storing a computer program;
- and
- a processor coupled to the memory and configured to execute the computer program to perform operations comprising:
- generating a desired guard symbol medium access control layer control element (MAC CE) when a preset trigger condition is met;
- and
- sending the desired guard symbol MAC CE to a second communication device,
- wherein both the first communication device and the second communication device are integrated access backhaul (IAB) nodes,
- wherein the generating the desired guard symbol MAC CE when the preset trigger condition is met comprises:
- the generating, when a first cell of an IAB node is configured or activated, the first cell is located in a third frequency band, and before the first cell is configured or activated, no cell is configured or activated in the third frequency band, the desired guard symbol MAC CE corresponding to the first cell by the IAB node.
A non-transitory computer-readable storage medium, storing a computer program to be executed by a processor of a first communication device, wherein the computer program, when executed by the processor of the first communication device, causes the processor to perform operations comprising:
- generating a desired guard symbol medium access control layer control element (MAC CE) when a preset trigger condition is met;
- and
- sending the desired guard symbol MAC CE to a second communication device,
- wherein both the first communication device and the second communication device are integrated access backhaul (IAB) nodes,
- wherein the generating the desired guard symbol MAC CE when the preset trigger condition is met comprises:
- the generating, when a first cell of an IAB node is configured or activated, the first cell is located in a third frequency band, and before the first cell is configured or activated, no cell is configured or activated in the third frequency band, the desired guard symbol MAC CE corresponding to the first cell by the IAB node.
