Scheduling Signaling Detection Control via RRC Stop Indications

Solution Overview

Problem

In LTE and new generation communication systems, the increased number of control regions to be detected by terminals leads to significant detection complexity and higher power consumption, as terminals perform multiple detections per downlink time domain unit.

Innovation Solution

A method and device where a base station sends target information to a terminal via RRC signaling to determine if a condition for stopping scheduling signaling detection is satisfied, including maximum scheduling signaling transmission, detection indication, or feature information to reduce unnecessary detections.
