Solution Overview

Problem

In wireless communication systems, the existing methods for decoding Enhanced-Multicast Broadcast Service (E-MBS) messages are inefficient due to repeated and unnecessary decoding of the E-MBS MAP, leading to high power usage and resource wastage, especially since transmission parameters change infrequently.

Innovation Solution

A signaling method and system that includes an indicator in the E-MBS MAP to specify when the next E-MBS MAP should be decoded, allowing subscriber stations to skip intermediate decoding and wake up only for the next scheduled decoding instance, reducing unnecessary decoding by more than 50% through indicators that count down to the next parameter change or sequence number.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If subscriber stations decode every E-MBS configuration message, then they ensure they have the latest transmission parameters, but power consumption increases and resource wastage occurs due to frequent unnecessary decoding

Engineering Contradiction:
Improveparameter update accuracyVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The base station performs preliminary action by including an indicator in the current E-MBS configuration message that specifies when the next configuration message will be transmitted. This allows subscriber stations to proactively schedule their next decoding operation without needing to decode every intermediate message, thereby reducing power consumption while ensuring they receive parameter updates timely.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The indicator field acts as a feedback mechanism from the base station to subscriber stations, providing advance information about when the next configuration message will be sent. This feedback enables subscriber stations to adjust their decoding behavior accordingly, decoding only when necessary and skipping intermediate messages, thus resolving the contradiction between reliable parameter updates and power consumption.

Inventive Principle:
Principle #23Feedback

2Reliability

If subscriber stations decode every E-MBS configuration message, then they maintain up-to-date configuration information, but processing overhead and resource usage increase significantly

Engineering Contradiction:
Improveconfiguration accuracyVSAvoidprocessing efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The base station provides preliminary information through the indicator field, telling subscriber stations exactly when the next configuration message will arrive. This allows subscriber stations to pre-schedule their processing resources, activating decoding only at the specified time rather than continuously monitoring and decoding every message, thereby improving processing efficiency while maintaining configuration accuracy.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The indicator field establishes a periodic decoding schedule where subscriber stations decode E-MBS configuration messages only at intervals specified by the indicator rather than continuously. This periodic action reduces processing overhead and resource usage while ensuring that configuration information is updated reliably at appropriate intervals.

Inventive Principle:
Principle #19Periodic action

3Reliability

If transmission parameters are updated frequently, then service quality improves, but subscriber stations experience increased power consumption due to more frequent decoding requirements

Engineering Contradiction:
Improveservice qualityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The base station uses the indicator field to provide preliminary notice of when parameter updates will occur. This allows the system to maintain frequent parameter updates for service quality while enabling subscriber stations to power down their decoders between updates, consuming power only when actually needed for decoding, thus resolving the contradiction between service quality and power consumption.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The indicator field provides feedback from the base station about the timing of parameter updates, allowing subscriber stations to synchronize their decoding operations with actual update events. This feedback mechanism ensures that frequent parameter updates maintain service quality while subscriber stations avoid unnecessary decoding operations, optimizing power consumption.

Inventive Principle:
Principle #23Feedback

AI summary

A base station comprises a transmitter configured to transmit a downlink frame. The downlink frame comprising a first configuration message associated with the configuration of Enhanced-Multicast Broadcast Service (E-MBS). The first configuration message comprises a field with an indicator to indicate a next configuration message to be decoded by a subscriber station. The subscriber station, upon decoding the first configuration message, refrains from decoding subsequent configuration messages that precede the next configuration message to be decoded by the subscriber station in accordance with the indicator.
