Data transmission method and apparatus, and electronic device

A data transmission method, applied to a first User Equipment (UE), the first UE being a Half-Duplex (HD) UE supporting Sub-Band Full-Duplex (SBFD) capability, comprising:

• determining a Physical Downlink Shared Channel (PDSCH) time-frequency resource and a SBFD time-frequency resource, wherein the PDSCH time-frequency resource and the SBFD time-frequency resource are located in a same Downlink (DL) time slot or a same special time slot, and the SBFD time-frequency resource is instructed to be used for Uplink (UL) and/or a guard band;
• when there is an overlapping resource between the PDSCH time-frequency resource and the SBFD time-frequency resource, determining an available time-frequency resource based on the PDSCH time-frequency resource and the SBFD time-frequency resource, wherein the available time-frequency resource is a time-frequency resource in the PDSCH time-frequency resource except the overlapping resource;
• and
• receiving DL data corresponding to the first UE based on the available time-frequency resource.

An electronic device, comprising:

• one or more processors, and one or more non-transitory machine-readable storage media, wherein the one or more non-transitory machine-readable storage media store machine-executable instructions capable of being executed by the one or more processors, wherein the one or more processors are configured to execute the machine-executable instructions to perform operations comprising:
• determining a Physical Downlink Shared Channel (PDSCH) time-frequency resource corresponding to a first User Equipment (UE) and a Sub-Band Full-Duplex (SBFD) time-frequency resource corresponding to a second UE, wherein the PDSCH time-frequency resource and the SBFD time-frequency resource are located in a same Downlink (DL) time slot or a same special time slot, and the SBFD time-frequency resource is instructed to be used for Uplink (UL) and/or a guard band;
• transmitting DL data corresponding to the first UE based on the PDSCH time-frequency resource, wherein the first UE is a Half-Duplex (HD) UE supporting SBFD capability;
• and
• receiving UL data corresponding to the second UE based on the SBFD time-frequency resource.
