Uplink Transmit Switching Configuration for Wireless Carrier Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing uplink transmit switching and sounding reference signal (SRS) carrier switching, particularly in terms of reducing switching overhead and conserving network resources, due to limitations in the number of allowable switches over a given time frame.
Innovation Solution
The implementation of a configuration that allows for uplink transmit switching and SRS carrier switching between component carriers, with a maximum number of allowable switches defined over a specific time period, ensuring that the third component carrier is treated as a two-port configuration for SRS carrier switching, thereby preventing uplink transmit switching during SRS carrier switching and optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If uplink transmit switching and SRS carrier switching are performed frequently to optimize network performance, then spectral efficiency and service quality are improved, but switching overhead and network resource consumption increase
Solution Approach 1:
The patent introduces a maximum number of allowable switches parameter that can be configured by the network. This parameter limits the total number of uplink transmit switches and SRS carrier switches within a specific time period, directly controlling the switching frequency to balance performance optimization with overhead reduction.
Solution Approach 2:
The patent implements dynamic switching control where the UE monitors the current switch count against the maximum allowable switches. When the limit is reached, further switching is prevented until the counter resets or is reconfigured, creating a dynamic adaptation mechanism that responds to network conditions and resource constraints.
2Reliability
If uplink transmit switching is performed to optimize uplink communication, then uplink performance is improved, but uplink communications may be dropped due to SRS carrier switching on another component carrier
Solution Approach 1:
The patent applies preliminary anti-action by preventing uplink transmit switching when an SRS carrier switch is currently occurring or when the maximum switch limit has been reached. This proactive prevention mechanism avoids the harmful effect of uplink communication drops by anticipating and blocking conflicting switch operations before they can occur.
Solution Approach 2:
The patent introduces a switch counter and control logic as an intermediary mechanism that mediates between uplink transmit switching and SRS carrier switching operations. This intermediary monitors the state of both switching types and enforces coordination rules, ensuring that they do not conflict and cause communication drops.
3Adaptability or versatility
If the maximum number of allowable switches is increased to allow more flexible switching, then switching flexibility is improved, but switching overhead and resource consumption increase
Solution Approach 1:
The patent implements partial action by allowing switching operations only up to the configured maximum limit. Instead of allowing unlimited switching for maximum flexibility, it deliberately restricts switching to a partial level that provides sufficient adaptability while preventing excessive switching that would increase overhead and complexity.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information that indicates an uplink transmit switching configuration for performing uplink transmit switching between a first component carrier and a second component carrier and a sounding reference signal (SRS) carrier switching configuration for performing SRS carrier switching between the second component carrier and a third component carrier, wherein the configuration information is associated with a maximum number of allowable switches over an amount of time. The UE may transmit, based at least in part on the configuration information, one or more signals associated with performing at least one of uplink transmit switching or SRS carrier switching. Numerous other aspects are described.
