Random Access Channel Coverage Enhancement via UE Request
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in ensuring reliable random access channel coverage, particularly in areas with poor signal quality, leading to dropped communications and degraded signal issues.
Innovation Solution
The method involves a user equipment (UE) receiving a random access response and requesting coverage enhancement, which is then granted by the base station through a contention resolution message, enabling techniques like repetition and frequency hopping to improve acknowledgment reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If coverage enhancement techniques are implemented, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by having the UE send a coverage enhancement request before the actual data transmission during the random access procedure. The base station evaluates and grants coverage enhancement resources in advance, allowing the UE to prepare for reliable transmission in poor coverage areas before the communication challenge arises.
Solution Approach 2:
The patent implements dynamics by making coverage enhancement configurable and adaptable. The base station can dynamically grant or deny coverage enhancement based on current network conditions and UE requirements. The UE can also adjust its coverage enhancement preferences based on its specific communication needs, creating a flexible system that adapts rather than being statically complex.
2Reliability
If signal quality is improved through coverage enhancement, then dropped connections are reduced, but transmission time increases
Solution Approach 1:
The patent applies partial action by implementing coverage enhancement selectively rather than universally. The base station evaluates each UE's coverage enhancement request and grants it only when necessary based on signal quality metrics and network conditions. This partial application of coverage enhancement techniques avoids the time overhead of always using enhanced transmission methods, while still providing connection stability when needed.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a random access response associated with a random access channel (RACH) procedure. The UE may transmit, based at least in part on receiving the random access response, data indicating a request for coverage enhancement associated with an acknowledgment associated with the RACH procedure. Numerous other aspects are described.
