1. A method for wireless communication, comprising:
transmitting, by a first network element, a resource status request to a second network element requesting measurements of resource status at a slice level of a slice, wherein the slice represents a logical network of a physical network infrastructure, wherein the first network element comprises at least one of: a control plane of a centralized unit, a centralized unit, or a base station, and wherein the second network element comprises at least one of: a user plane of a centralized unit, a distributed unit, or a base station;
receiving, by the first network element, a resource status response from the second network element in response to the resource status request;
receiving, by the first network element, a resource status update message from the second network element, wherein the resource status update message comprises one or more measurement results based on the measurements, wherein the one or more measurement results comprise load information at the slice level represented as a list of Single Network Slice Selection Assistance information (S-NSSAI) items, and wherein each item of the list of S-NSSAI items is identified by an S-NSSAI value and indicates at least a capacity load associated with the S-NSSAI item; and
performing, by the first network element, load balancing with the second network element based on the load information at the slice level.
