Abstract

Provided are a method for data feedback processing and a device. The method is applied to a first terminal and includes: determining a plurality of second terminals as feedback receiving terminals, upon determining that feedback is required to be provided in a first time slot for first data sent by the plurality of second terminals; determining whether the first terminal supports simultaneous feedback; and determining, according to a service priority level upon determining that the first terminal does not support simultaneous feedback, a target terminal having the highest service priority level from the plurality of feedback receiving terminals, and sending, in the first time slot, feedback information to the target terminal having the highest service priority level.

First claim

What is claimed is:

1 . A method for data feedback processing, applied to a first terminal, the method comprising:
determining a plurality of second terminals as feedback receiving terminals, upon determining that feedback is required to be provided in a first time slot for first data sent by the plurality of second terminals; determining whether the first terminal supports simultaneous feedback; and determining, according to a service priority level upon determining that the first terminal does not support simultaneous feedback, a target terminal having the highest service priority level from the plurality of feedback receiving terminals, and sending, in the first time slot, feedback information to the target terminal having the highest service priority level, wherein the feedback information is configured to indicate a receiving status of the first terminal for the first data.

2 . The method as claimed in 1 , wherein the service priority level comprises a first data priority level and/or a second terminal priority level.

3 . The method as claimed in 1 , comprising:
respectively sending, in the first time slot upon determining that the first terminal supports simultaneous feedback, corresponding feedback information to the plurality of feedback receiving terminals.

4 . The method as claimed in 3 , wherein said respectively sending, in the first time slot upon determining that the first terminal supports simultaneous feedback, corresponding feedback information to the plurality of feedback receiving terminals comprises:
respectively sending, based on a plurality of consecutive feedback resources, in the first time slot upon determining that the first terminal supports simultaneous feedback, corresponding feedback information to the plurality of feedback receiving terminals.

5 . The method as claimed in 1 , wherein said determining whether the first terminal supports simultaneous feedback comprises:
determining, according to at least one of a transmission power supported by the first terminal, a distribution status of feedback resources obtained, feedback information that is required to be sent, and a feedback transmission power required to transmit the feedback information, whether the first terminal supports simultaneous feedback.

6 . The method as claimed in 1 , wherein said determining, according to a service priority level upon determining that the first terminal does not support simultaneous feedback, a target terminal having the highest service priority level from the plurality of feedback receiving terminals, and sending, in the first time slot, feedback information to the target terminal having the highest service priority level comprises:
upon determining that the first terminal does not support simultaneous feedback, determining, according to path losses of sidelinks between the first terminal and the feedback receiving terminals, a feedback transmission power for sending the feedback information to the feedback receiving terminals; determining whether the first terminal is capable of sending, at the feedback transmission power, the feedback information to the feedback receiving terminals, and determining, as a target terminal, a feedback receiving terminal that enables the first terminal to perform feedback information transmission at the feedback transmission power; in a case of more than one target terminal, selecting a target terminal having the highest service priority level from of the more than one target terminal according to the service priority level; and sending, in the first time slot, the feedback information to the target terminal having the highest service priority level.

7 . The method as claimed in any one of claim 1 , comprising:
upon determining that the first terminal does not support simultaneous feedback, sending a feedback adjustment request to at least one of the plurality of feedback receiving terminals, wherein the feedback adjustment request comprises at least one of an adjustment to feedback interval information, an adjustment to reception time information about reception of the first data, and an adjustment to a designated frequency; receiving a feedback adjustment instruction sent by the feedback receiving terminal in response to the feedback adjustment request, wherein the feedback adjustment instruction comprises at least one of adjusted feedback interval information, adjusted reception time information, and an adjusted designated frequency; and respectively sending, according to the feedback adjustment instruction, corresponding feedback information to the plurality of feedback receiving terminals.

8 . The method as claimed in 7 , wherein said respectively sending, according to the feedback adjustment instruction, corresponding feedback information to the plurality of feedback receiving terminals comprises at least one of:
sending, in a second time slot over the adjusted designated frequency, corresponding feedback information to a feedback receiving terminal that sends a corresponding feedback adjustment instruction; sending, in a second time slot over the designated frequency, corresponding feedback information to a feedback receiving terminal that sends a corresponding feedback adjustment instruction; or sending, in a second time slot over the adjusted designated frequency, corresponding feedback information to a feedback receiving terminal that sends a corresponding feedback adjustment instruction.

9 . A device for data feedback processing, applied to a first terminal, the device comprising:
a memory; and at least one processor coupled to the memory and configured to:
determine, upon determining that feedback is required to be provided in a first time slot for first data sent by a plurality of second terminals, wherein the plurality of second terminals are determined as feedback receiving terminals;
determine whether the first terminal supports simultaneous feedback; and
determine, according to a service priority level upon determining that the first terminal does not support simultaneous feedback, a target terminal having the highest service priority level from the plurality of feedback receiving terminals, and sends, in the first time slot, feedback information to the target terminal having the highest service priority level,
wherein the feedback information is configured to indicate a receiving status of the first terminal for the first data.

10 . The device according to claim 9 , wherein the service priority level comprises a first data priority level and/or a second terminal priority level.

11 . The device according to claim 9 , wherein the at least one process is configured to:
respectively send, in the first time slot upon determining that the first terminal supports simultaneous feedback, corresponding feedback information to the plurality of feedback receiving terminals.

12 . The device according to claim 11 , wherein the at least one process configured to:
respectively send, based on a plurality of consecutive feedback resources, in the first time slot upon determining that the first terminal supports simultaneous feedback, corresponding feedback information to the plurality of feedback receiving terminals.

13 . The device according to claim 9 , wherein the at least one process is configured to:
determine, according to at least one of a transmission power supported by the first terminal, a distribution status of feedback resources obtained, feedback information that is required to be sent, and a feedback transmission power required to transmit the feedback information, whether the first terminal supports simultaneous feedback.
