US 11,997,054 B2 · Resource coordination for half duplex communications

Abstract

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.

Dependent claims

A method for wireless communications at a relay device in communication with a parent network node and a child network node, comprising:

identifying a set of resources partitioned into a first subset of resources for the relay device and a second subset of resources for the parent network node and the child network node;
receiving, from an anchor node, an indication of a direction table for a slot of the second subset of resources, wherein the direction table is based at least in part on respective slot structures for the parent network node and the child network node, and wherein the direction table indicates a functionality of the relay device for communications scheduled by the relay device during the 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 direction table;
and
communicating with one or more devices during the slot of the second subset of resources according to the scheduled communications.

A relay device for wireless communications with a parent network node and a child network node, comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories and operable to execute the code to cause the relay device to:
identify a set of resources partitioned into a first subset of resources for the relay device and a second subset of resources for the parent network node and the child network node;
receive, from an anchor node, an indication of a direction table for the relay device for a slot of the second subset of resources, wherein the direction table is based at least in part on respective slot structures for the parent network node and the child network node, and wherein the direction table indicates a functionality of the relay device for communications scheduled by the relay device during the slot of the second subset of resources;
schedule communications in the slot of the second subset of resources based at least in part on the direction table;
and
communicate with one or more devices during the slot of the second subset of resources according to the scheduled communications.
