RESOURCE COORDINATION FOR HALF DUPLEX COMMUNICATIONS
Methods, systems, and devices for wireless communications are described that provide for resource allocation in an integrated access and backhaul (IAB) network. A relay node in an IAB network may be assigned a first resource partition that is different from a second resource partition for the child and parent nodes. Based on a resource configuration (e.g., for a slot) of the second resource partition, the relay node may opportunistically utilize the second resource partition for communications. For instance, the relay node may determine a direction table based on the resource configurations of the child and parent nodes, which may be used to perform uplink or downlink communications in one or more symbols of the second resource partition. The relay node may also identify flexible symbols as free or non-free when determining the direction table.
1 . A method for wireless communications at a relay device, comprising:
identifying a set of resources partitioned into a first subset of resources for the relay device and a second subset of resources for a parent network node and a child network node in communication with the relay device;
receiving, from the parent network node, a first resource configuration for a slot of the second subset of resources;
scheduling communications in the slot of the second subset of resources based at least in part on the first resource configuration; and
communicating with one or more devices during the slot of the second subset of resources according to the scheduled communications.
