Wireless communication method and apparatus

A method, wherein the method comprises:

• receiving, by a receiver, second information from a central node,
• wherein the second information indicates a first topology, the first topology is determined by the central node based on first information, and a radio frequency identification (RFID) reader comprises the receiver and an exciter,
• wherein the exciter is deployed on a first distributed node;
• or the receiver is deployed on the central node;
• or the receiver is deployed on a second distributed node,
• wherein the method is applied to an IAB system, the central node is a donor node in the IAB system, the first distributed node is a first IAB node in the IAB system, and the second distributed node is a second IAB node in the IAB system, and
• wherein the first information comprises at least one of status information of the receiver or status information of the exciter,
• the status information of the receiver including at least one of load information indicating current processing capacity of the receiver or information about a maximum quantity of exciters that can be bound to the receiver, or
• the status information of the exciter including position information of the exciter;
• and
• when the receiver is deployed on the second distributed node, sending, by the receiver, fourth information to the central node, wherein the fourth information indicates the central node to select a first AMF network element, and the first AMF network element supports authorization of the receiver.

An apparatus, comprising:

• a transceiver;
• at least one processor;
• and
• one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to cause the apparatus to:
• determine a first topology between a receiver and an exciter based on first information,
• wherein a radio frequency identification (RFID) reader comprises the receiver and the exciter,
• wherein the exciter is deployed on a first distributed node;
• or the receiver is deployed on a central node;
• or the receiver is deployed on a second distributed node,
• wherein the apparatus is an integrated access and backhaul (IAB) system, the central node is a donor node in the IAB system, the first distributed node is a first IAB node in the IAB system, and the second distributed node is a second IAB node in the IAB system, and
• wherein the first information comprises at least one of status information of the receiver or status information of the exciter,
• the status information of the receiver including at least one of load information indicating current processing capacity of the receiver or information about a maximum quantity of exciters that can be bound to the receiver, or
• the status information of the exciter including position information of the exciter;
• and
• send second information to the receiver, wherein the second information indicates the first topology, and wherein when the receiver is deployed on the second distributed node, the programming instructions for execution by the at least one processor cause the apparatus to:
• receive fourth information from the receiver, wherein the fourth information indicates the central node to select a first access and mobility management function (AMF) network element;
• determine the first AMF network element based on the fourth information, wherein the first AMF network element supports authorization of the receiver;
• send fifth information to the first AMF network element, wherein the fifth information indicates the first AMF network element to authorize the receiver;
• and
• receive sixth information from the first AMF network element, wherein the sixth information comprises information about the receiver.

An apparatus, comprising:

• a transceiver;
• at least one processor;
• and
• one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to cause the apparatus to:
• receive second information from a central node,
• wherein the second information indicates a first topology, the first topology is determined by the central node based on first information, the apparatus is or is part of a receiver, and a radio frequency identification (RFID) reader comprises the receiver and an exciter,
• wherein the exciter is deployed on a first distributed node;
• or the receiver is deployed on the central node;
• or the receiver is deployed on a second distributed node,
• wherein the apparatus is an integrated access and backhaul (LAB) system, the central node is a donor node in the IAB system, the first distributed node is a first IAB node in the IAB system, and the second distributed node is a second IAB node in the IAB system, and
• wherein the first information comprises at least one of status information of the receiver or status information of the exciter,
• the status information of the receiver including at least one of load information indicating current processing capacity of the receiver or information about a maximum quantity of exciters that can be bound to the receiver, or
• the status information of the exciter including position information of the exciter;
• and
• when the receiver is deployed on the second distributed node, send fourth information to the central node, wherein the fourth information indicates the central node to select a first AMF network element, and the first AMF network element supports authorization of the receiver.
