Parallel RRC Message Segmentation with Procedure Number
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in 3GPP NR and LTE, face challenges in processing downlink RRC messages sequentially, which limits the parallel transmission of segmented RRC messages due to the lack of identification in the ASN.1 format, leading to incorrect reassembly of original RRC messages.
Innovation Solution
Introducing new message versions for segmented RRC messages, such as DLDedicatedMessageSegment2 and ULDedicatedMessageSegment2, which include a procedure number and RRC message type, allowing the recipient to unambiguously identify and reassemble message segments, enabling parallel transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If segmented RRC messages are transmitted in parallel, then communication efficiency is improved, but message segments cannot be correctly identified and reassembled due to lack of procedure number indication
Solution Approach 1:
The patent introduces a procedure number as an intermediary identifier in segmented RRC messages. This procedure number acts as a mediator that links message segments to their corresponding original messages, enabling correct identification and reassembly even when segments from multiple messages are transmitted in parallel. The procedure number is included in each segmented message to unambiguously identify which original message the segment belongs to.
2Reliability
If sequential processing of RRC messages is maintained, then message processing reliability is ensured, but transmission parallelism is limited
Solution Approach 1:
The patent divides large RRC messages into multiple segments that can be transmitted independently in parallel. Each segment is marked with a procedure number that identifies its parent message. This segmentation allows the transmitting side to send multiple segments simultaneously while the receiving side can reliably process them by using the procedure numbers to reassemble the original messages in the correct order, thus achieving both parallel transmission and reliable processing.

AI summary
Apparatuses, methods, and systems are disclosed for transmitting message segments in parallel. One method includes segmenting a first PDCP layer SDU message into a plurality of first segments and transmitting a first set of segmented RRC messages to a second communication entity. The first method includes segmenting a second PDCP layer SDU message into a plurality of second segments and transmitting a second set of segmented RRC messages to the second communication entity in parallel with the first set of segmented RRC messages. Each of the segmented RRC messages includes one of the first or second segments and includes a procedure number that indicates to which procedure the included segment corresponds.
