Relay Beam Switching Gap Control for Consistent Power Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for appropriate control of beam and power switching in communication apparatuses that relay signals between user terminals and radio base stations, as current definitions lack specific control for transient periods during switching, leading to inconsistencies in power and beam recognition.
Innovation Solution
The communication apparatus includes a control section that configures a specific period before switching to a first beam or power state, allowing for appropriate control of the transition to ensure consistent and efficient communication operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam switching is performed without configuring a specific period before the first period, then the communication operation can start immediately, but inconsistencies in beam and power recognition occur between the network and the relay apparatus
Solution Approach 1:
The patent applies preliminary action by configuring a specific period (gap period) before the first period where the beam is actually used. This gap period is set in advance to allow the relay apparatus to complete beam switching and power adjustment before the network expects the new beam to be active, ensuring both parties recognize the beam state consistently.
2Reliability
If a specific period is configured before beam switching, then recognition consistency is improved, but the communication operation is delayed
Solution Approach 1:
The gap period is configured in advance before beam switching occurs, allowing the relay apparatus to prepare for the beam change without delaying the actual communication operation. The network can schedule resources considering this gap period, maintaining overall system efficiency while ensuring recognition consistency.
Solution Approach 2:
The patent makes the beam switching process dynamic by allowing flexible configuration of the gap period length and positioning it appropriately within the communication framework. This enables the system to adapt the switching timeline to balance reliability requirements with operational efficiency demands.
3Speed
If beam switching is performed without a gap period, then the switching speed is fast, but power and beam state recognition becomes inconsistent between network and relay
Solution Approach 1:
The gap period acts as an intermediary time window between the old beam usage and the new beam usage. During this gap period, the relay apparatus completes the beam switching and power adjustment processes, serving as a buffer that ensures both the network and relay apparatus recognize the beam state consistently before actual communication on the new beam begins.

AI summary
This communication device comprises: a control unit that, when a beam relating to a communication operation executed between a base station and a terminal by the communication device is switched to a first beam, sets a specific period before a first period in which the first beam is used, and switches said beam to the first beam; and a communication unit that transmits or receives a signal by using the first beam.
