Component Carrier Signal Measurement Using UE Capability Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in managing resource signal reception across multiple component carriers due to synchronization issues, leading to unnecessary resource consumption and inefficient resource allocation.
Innovation Solution
A UE transmits an indication of the number of resource signals it can receive via multiple component carriers based on a reference slot, allowing the base station to configure measurements accordingly, thereby optimizing resource usage and synchronization.

Engineering Contradiction Analysis
1Productivity
If the base station transmits resource signals without considering UE reception capability indication, then resource signal transmission can proceed continuously, but network and communication resources are consumed unnecessarily
Solution Approach 1:
The UE transmits an indication of its resource signal reception capability to the base station, providing feedback about its actual reception ability. The base station uses this feedback information to adjust resource signal transmission configurations, ensuring that only necessary resource signals are transmitted and avoiding waste of network and communication resources on signals the UE cannot receive.
Solution Approach 2:
The system dynamically adjusts resource signal transmission based on UE capability indications. Instead of continuous fixed transmission, the base station modifies transmission parameters (such as number of resource signals, timing, and configuration) according to the UE's reported reception capability, optimizing resource utilization in real-time.
2Productivity
If the UE indicates its resource signal reception capability accurately, then resource allocation can be optimized, but the UE must process and transmit capability information
Solution Approach 1:
The UE extracts and transmits only the essential capability indication information (the number of resource signals it can receive) to the base station, rather than providing comprehensive capability details. This selective information transmission reduces UE processing burden while still enabling the base station to optimize resource allocation effectively.
Solution Approach 2:
The system changes the parameter of capability indication from detailed capability descriptions to a simplified numerical parameter (number of resource signals). This parameter transformation reduces the complexity of UE processing and transmission while maintaining sufficient information for the base station to adjust resource signal transmission appropriately.
3Ease of operation
If resource signals are transmitted without synchronization consideration, then transmission can be simplified, but synchronization issues cause inefficient resource allocation
Solution Approach 1:
The UE performs preliminary action by indicating its reception capability before the base station finalizes resource signal transmission configuration. This advance capability notification allows the base station to pre-adjust transmission parameters and synchronization settings, ensuring efficient resource allocation without complicating the overall transmission process.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an indication of a number of resource signals that the UE is capable of receiving via multiple component carriers during a time period, the number of resource signals based at least in part on a reference slot of a reference component carrier of the multiple component carriers. The UE may receive a configuration for measuring resource signals based at least in part on transmission of the indication. Numerous other aspects are described.
