Abstract

A system and method for configuring feedback channel allocation and transmission during sidelink communication are disclosed herein. In one embodiment, an example wireless communication method includes: configuring, by a wireless communication node, a plurality of resource pools for sidelink communications. The method further includes configuring, by the wireless communication node, a first list indicating a first subset of the plurality of resource pools and a second list indicating a second subset of the plurality of resource pools. Each of the plurality of resource pools includes at least one of a first type of resources that are each configured for a plurality of wireless communication devices to communicate control information in the sidelink communications, a second type of resources that are each configured for the plurality of wireless communication devices to communicate data in the sidelink communications, and a third type of resources that are each configured for the plurality of wireless communication devices to communicate feedback in the sidelink communications.
