Abstract
Aspects of the subject disclosure may include, for example, performing dynamic beam selection and coordination to support space division multiplexing (SDM) and Full Duplex operation for integrated access and backhaul (IAB) in 5G new radio (NR) networks. The subject disclosure further describes how an IAB node and a serving parent node can coordinate beams used for access and backhaul links dynamically with over-the-air signaling. Other embodiments are described in the subject disclosure.
Claims20
A device, comprising:
- a processing system including a processor;
- and
- a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
- transmitting, from a first integrated access and backhaul (IAB) node, a first message to a second IAB node, the first message including an indication of spatial multiplexing capabilities of the first IAB node;
- and
- receiving, from the second IAB node, a second message including first configuration information for first spatial resources to be used for backhaul purposes, and second configuration information for second spatial resources to be used for user equipment (UE) communications, wherein the first configuration information specifies configuring the first spatial resources at an antenna panel level granularity, at an antenna beam level granularity, or at any combination thereof.
A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, the operations comprising:
- transmitting, from a first integrated access and backhaul (IAB) node, a first message to a second IAB node, the first message including an indication of spatial multiplexing capabilities of the first IAB node;
- and
- receiving, from the second IAB node, a second message including first configuration information for first spatial resources to be used for backhaul purposes, and second configuration information for second spatial resources to be used for user equipment (UE) communications, wherein the first configuration information specifies configuring the first spatial resources at an antenna panel level granularity, at an antenna beam level granularity, or at any combination thereof.
A method, comprising:
- transmitting, by a processing system including a processor, from a first integrated access and backhaul (IAB) node, a first message to a second IAB node, the first message including an indication of spatial multiplexing capabilities of the first IAB node;
- and
- receiving, by the processing system, from the second IAB node, a second message including first configuration information for first spatial resources to be used for backhaul purposes, and second configuration information for second spatial resources to be used for user equipment (UE) communications, wherein the first configuration information specifies configuring the first spatial resources at an antenna panel level granularity, at an antenna beam level granularity, or at any combination thereof.
