AI Technical Summary

Technical Problem

The existing carrier aggregation (CA) technology in telecommunications faces challenges with uplink channel resource management, particularly with the dedicated resource allocation for physical uplink control channels (PUCCH) per serving cell, which leads to resource bottlenecks and reduced cell capacity.

Method used

A network device allocates a first set of resources to an uplink control channel for a secondary cell (SCell), where these resources can also be allocated to another SCell, allowing for resource sharing and overbooking to enhance PUCCH resource utilization.

Benefits of technology

This approach effectively increases the number of supported CA UEs per cell, reduces the PRB resources occupied by PUCCH, and enhances the overall uplink throughput by optimizing the use of PUCCH resources.

Abstract

Embodiments of the present disclosure disclose devices, methods and apparatuses for uplink channel enhancement. In the embodiments, a network device allocates, based on an addition of a secondary cell (SCell) a first set of resources to an uplink control channel for the SCell. The first set of resources at least has been allocated to an uplink control channel for another SCell. In this way, the performance of the uplink channel can be improved.
