Carrier configuration method and related device

A communications device, comprising:

• a processor, and
• a memory, configured to couple to the processor and store program instructions that, when executed by the processor, cause the communication device to perform the following operations:
• receiving a first message comprising configuration information of a secondary cell, wherein the communication device is configured with a first carrier and a second carrier of a first serving cell, with the second carrier being a supplementary uplink (SUL) carrier of the first carrier and configured with a first uplink as an SUL of the first serving cell, wherein the secondary cell comprises a second serving cell corresponding to the second carrier, wherein the configuration information of the secondary cell comprises a downlink configuration of the second carrier, with the downlink configuration of the second carrier being used to configure a first downlink of the second carrier for the second serving cell and to aggregate the first downlink of the second carrier with a second downlink of the first carrier for the first serving cell;
• and
• configuring the second serving cell corresponding to the second carrier based on the configuration information of the secondary cell such that the first uplink of the second carrier remains as the SUL of the first serving cell, the SUL of the first serving cell is deactivated, or a second uplink of the second carrier for the second serving cell is aggregated with a third uplink of the first carrier for the first serving cell.

A non-transitory computer-readable storage medium on which a computer program is stored, wherein the program, when executed by a processor, implements the following operations:

• receiving a first message comprising configuration information of a secondary cell, wherein the communication device is configured with a first carrier and a second carrier of a first serving cell, with the second carrier being a supplementary uplink (SUL) carrier of the first carrier and configured with a first uplink as an SUL of the first serving cell, wherein the secondary cell comprises a second serving cell corresponding to the second carrier, wherein the configuration information of the secondary cell comprises a downlink configuration of the second carrier, with the downlink configuration of the second carrier being used to configure a first downlink of the second carrier for the second serving cell and to aggregate the first downlink of the second carrier with a second downlink of the first carrier for the first serving cell;
• and
• configuring the second serving cell corresponding to the second carrier based on the configuration information of the secondary cell such that the first uplink of the second carrier remains as the SUL of the first serving cell, the SUL of the first serving cell is deactivated, or a second uplink of the second carrier for the second serving cell is aggregated with a third uplink of the first carrier for the first serving cell.
