Joint System Information Encoding for Multi-Beam Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in encoding system information for multiple beams, leading to large overhead due to repetition of identical parameters, which is undesirable in energy-conscious network designs.
Innovation Solution
The system encodes system information jointly for multiple cells and beams, using a common field for shared information and beam-specific fields indexed to each beam, reducing redundant data transmission and optimizing energy consumption.

Engineering Contradiction Analysis
1Loss of information
If existing formats for system information encoding are used to encompass multiple beams, then system information can be transmitted to user equipment, but repetition of many SIB parameters with identical values results in unnecessarily large overhead
Solution Approach 1:
The system information is segmented into two distinct parts: a common part containing parameters that are identical across multiple beams, and beam-specific parts containing only the parameters that differ for each beam. This segmentation eliminates the repetition of identical parameters while ensuring complete system information transmission.
Solution Approach 2:
The patent merges the encoding of system information for multiple beams into a single consolidated message structure. By combining the common part (shared across all beams) with individual beam-specific parts, the system transmits multiple beams' information efficiently in one message rather than repeating full SIBs for each beam.
2Reliability
If system information is encoded with full repetition for multiple beams, then each beam receives complete information, but energy consumption in the network increases
Solution Approach 1:
The patent extracts only the necessary beam-specific parameters from the full system information and transmits them separately from the common part. User equipment can reconstruct complete system information for each beam by combining the common part with the relevant beam-specific part, thereby reducing the total transmission energy while maintaining information availability.
3Ease of operation
If existing encoding formats are used for multiple beams, then system information is transmitted, but the message size becomes unnecessarily large
Solution Approach 1:
The message is segmented into a common part and beam-specific parts, where the common part is transmitted once and shared by all beams, and only the necessary beam-specific parameters are transmitted additionally. This segmentation dramatically reduces the total message size compared to transmitting full SIBs for each beam separately.

AI summary
An apparatus, system and method for encoding system information from multiple cells and beams in a communication system. In one embodiment, the apparatus is operable in a communication system including a first beam and a second beam, and is configured to construct a system information block for the first beam. The system information block includes a common field having common system information associated with the first beam and the second beam, and a first beam specific field having first beam specific system information indexed to the first beam. The apparatus is also configured to transmit the system information block to a user equipment for access to the communication system.
