Wireless Backhaul Random Access Target Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless backhaul networks, the existing random access procedures often result in unnecessary resource consumption and complexity due to non-target base stations receiving random access messages, which hampers the efficient establishment of connections between new and target base stations.
Innovation Solution
A base station determines specific parameters associated with a target base station to configure a transmission strategy for the first random access message, allowing only the target base station to respond, thereby reducing resource usage and simplifying the connection establishment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a base station transmits random access messages without configuring target-specific parameters, then the transmission process is simple, but non-target base stations receive and process the messages causing unnecessary resource consumption
Solution Approach 1:
The patent applies local quality by configuring target base station-specific parameters (such as target base station identifier, time window, frequency resources) in the random access message. This allows the transmission process to be simple for the sender while ensuring that only the intended target base station processes the message, eliminating unnecessary resource consumption at non-target base stations.
2Device complexity
If random access messages are transmitted without target identification parameters, then the message format is simple, but connection establishment efficiency is reduced due to unnecessary processing
Solution Approach 1:
The patent applies preliminary action by pre-configuring target base station parameters in the random access message before transmission. This includes setting the time window for response, frequency resources, and target identifier. The receiving base station can then quickly identify whether to process the message based on these pre-configured parameters, significantly improving connection establishment efficiency without substantially increasing message format complexity.
3Adaptability or versatility
If base stations use conventional random access procedures, then the procedure is standardized, but unnecessary processing occurs at non-target base stations increasing overall complexity
Solution Approach 1:
The patent applies parameter changes by modifying the random access message parameters to include target base station-specific information such as target identifier, time window, and frequency resources. This maintains compatibility with standardized procedures while adding selective processing capability. Non-target base stations can ignore the message by comparing the target identifier with their own identity, thereby reducing unnecessary processing complexity while maintaining standardization.

AI summary
Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine a transmission configuration for a first random access message based at least in part on one or more parameters associated with a target base station for initiating a backhaul connection. The transmission configuration may include information associated with a physical random access channel (PRACH) resource associated with transmitting the first random access message. The PRACH resource differs from a PRACH resource associated with a transmission of a random access message by a user equipment. The base station may transmit the first random access message using the transmission configuration. Numerous other aspects are provided.
