Receiver Burst Decoding for Lower GSM/GPRS Power Use

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional GSM/GPRS communication systems require receivers to remain powered for the entire duration of encoded data block reception, leading to high power consumption, especially in idle or repetitive data scenarios.

Innovation Solution

The system allows decoding and detection of encoded data blocks upon reception of only a portion of the data block, leveraging good signal conditions and repetitive data patterns to reduce the need for full data block reception, utilizing a detector and determiner to assess signal quality and coding schemes to selectively recover the data block.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the receiver remains powered for the entire duration of encoded data block reception, then complete data block reception is ensured, but power consumption increases

Engineering Contradiction:

Improvedata reception completenessVSAvoidreceiver power consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies partial action by enabling the receiver to perform decoding operations after receiving only a portion of the encoded data block (e.g., after 2 out of 4 bursts) rather than waiting for the complete block. This allows the receiver to potentially exit early and reduce power consumption while still recovering the informational content through selective decoding and CRC verification

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system dynamically adjusts the reception duration based on signal conditions and decoding success. The receiver monitors signal quality and attempts decoding at intermediate points, adapting the reception time to the actual channel conditions rather than using a fixed reception duration for all scenarios

Inventive Principle:

Principle #15Dynamics

2Use of energy by moving object

If decoding is performed upon reception of only a portion of the encoded data block, then receiver power consumption is reduced, but data reception reliability may be compromised

Engineering Contradiction:

Improvereceiver power consumptionVSAvoiddata reception completeness

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The patent implements feedback through CRC (cyclic redundancy check) verification after partial decoding attempts. The receiver decodes the received portion and verifies data integrity using CRC checks, then uses this feedback to determine whether to continue receiving remaining bursts or exit early, ensuring reliability while enabling power savings

Inventive Principle:

Principle #23Feedback

AI summary

Apparatus, and an associated method, for recovering the informational content of an encoded data block. Data bursts are delivered to a receiver. A series of data bursts together include all of the informational content of the encoded data block. A detector detects delivery to the receiver of the data bursts. A determiner determines indicia associated with the communicated data. And, responsive thereto, the data is decoded, selectably utilizing fewer than all of the data bursts that form the encoded data block.
