Reduced Capability UE CORESET0 and SS0 Configuration via MIB Field
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies face challenges in efficiently configuring control resource sets and search spaces for reduced capability user equipment (UEs), leading to increased radio resource consumption and inefficiencies in signaling system information transmission.
Innovation Solution
The method involves identifying a CORESET0 field or SS0 field in a master information block (MIB) and determining the corresponding configuration based on whether the UE is a reduced capability UE, allowing for the interpretation of specific values to point to different configurations, thereby conserving radio resources by reducing the need for additional signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate signaling is used to indicate CORESET0 and SS0 configurations for reduced capability UEs, then configuration accuracy is improved, but radio resource consumption increases
Solution Approach 1:
The patent combines the indication of CORESET0 configuration and SS0 configuration into a single signaling message transmitted from the base station to the UE. This merging of previously separate signaling functions reduces the total amount of radio resources consumed while maintaining the ability to provide accurate configurations for reduced capability UEs through a unified indication mechanism
2Reliability
If multiple signaling messages are transmitted to configure CORESET0 and SS0, then configuration reliability is improved, but signaling overhead increases
Solution Approach 1:
The patent merges multiple signaling messages into a single consolidated indication that simultaneously conveys both CORESET0 and SS0 configuration information. This approach maintains configuration reliability by ensuring both parameters are properly indicated while reducing signaling overhead by eliminating redundant message transmissions
3Adaptability or versatility
If additional signaling is introduced to support reduced capability UEs, then device compatibility is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal indication mechanism that serves both reduced capability UEs and normal UEs through the same signaling infrastructure. The single signaling message can accommodate different UE types by appropriately indicating CORESET0 and SS0 configurations, thereby improving device compatibility without requiring separate complex signaling paths for different UE categories

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify at least one of a control resource set zero (CORESET0) field or a search space zero (SS0) field in a master information block (MIB). The UE may identify, based at least in part on whether the UE is a reduced capability UE, at least one of: a CORESET0 configuration associated with a first value indicated in the CORESET0 field, or an SS0 configuration associated with a second value indicated in the SS0 field. Numerous other aspects are provided.
