Abstract

Provided in the present disclosure are an electronic device and method for wireless communication, and a computer-readable storage medium. The electronic device comprises: a processing circuit, which is configured to: provide configuration information to a receiving terminal device in sidelink communication, the configuration information being used to configure an additional physical sidelink feedback channel (PSFCH) resource that is used by the receiving terminal device to send a hybrid automatic repeat request (HARQ)) feedback, the additional PSFCH resource being a resource other than a PSFCH resource that is already configured and that is pool-specific; and acquire the HARQ feedback from the receiving terminal device on the basis of the configuration information.

provide second configuration information to the receiving terminal device via the sidelink communication, the second configuration information to be used by the receiving terminal device to configure additional PSFCH resources, other than the pool-specific PSFCH resources, the additional PSFCH resources selected by the electronic apparatus for use by the receiving terminal device to transmit the HARQ feedback to the electronic apparatus,
wherein the additional PSFCH resources selected by the electronic apparatus have a lower latency than the pool-specific PSFCH resources,
transmit information to a receiving terminal device via the sidelink communication, and
acquire, based on one of the first or second configuration information, HARQ feedback relative to the transmitted information from the receiving terminal device via the pool-specific PSFCH resources or the additional PSFCH resources,
wherein the additional PSFCH resources are preferentially used for the HARQ feedback.

2. The electronic apparatus according to claim 1 , wherein the processing circuitry is configured to provide the second configuration information to the receiving terminal device via one or more of the following: PC5-RRC signaling, MAC CE, or sidelink control information (SCI).

3. The electronic apparatus according to claim 1 , wherein the second configuration information comprises an indicator that indicates whether the additional PSFCH resources are configured.

4. The electronic apparatus according to claim 3 , wherein the indicator is represented by a field indicating a timing relationship between a Physical Sidelink Shared Channel (PSSCH) and the HARQ feedback.

5. The electronic apparatus according to claim 4 , wherein, based on the field indicating the timing relationship between the PSSCH and the HARQ feedback indicates a latency of 0, the field represents that the additional PSFCH resources are configured.

6. The electronic apparatus according to claim 1 , wherein the second configuration information comprises pattern information which indicates a time-frequency location of the additional PSFCH resources.

7. The electronic apparatus according to claim 1 , wherein the additional PSFCH resources are located within a same time slot as resources assigned to the electronic apparatus for transmission of an associated Physical Sidelink Shared Channel (PSSCH) to the receiving terminal device.

8. The electronic apparatus according to claim 7 , wherein the additional PSFCH resources are spaced apart from a last Orthogonal Frequency Division Multiplexing (OFDM) symbol of the PSSCH by one or two OFDM symbols.

9. The electronic apparatus according to claim 1 , wherein the additional PSFCH resources are the same as resources of assigned to the electronic apparatus for transmission of an associated Physical Sidelink Shared Channel (PSSCH) to the receiving terminal device in a frequency domain, or are a part of frequency domain resources of the associated PSSCH.

10. The electronic apparatus according to claim 1 , wherein, in K logically contiguous time slots, the information is transmitted in a first time slot of the K logically contiguous time slots, the pool-specific PSFCH resources are located in a first-plus-Kth time slot of the K logically contiguous time slots, and the additional PSFCH resources are located in at least one of the first time slot or a second time slot of the K logically contiguous time slots, where K is an integer greater or equal to 3.
