Solution Overview

Problem

In scheduled wireless communication environments, spontaneous location determination procedures are hindered when a non-associated client station requests participation during an assigned communication period of another client station, leading to delays, increased power consumption, and network traffic, as the access point cannot timely respond to both the request and its obligations to associated client stations using traditional single recipient frame structures.

Innovation Solution

Implementing a multiple recipient frame structure that encapsulates data for the associated client station and location determination information for the non-associated client station, allowing the access point to respond to the spontaneous request while fulfilling its obligations to associated clients by transmitting a single frame that includes both data and location determination information during the assigned communication period.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the access point uses traditional single recipient frame structures to respond to location determination requests, then the response can be simple and straightforward, but the access point cannot timely respond to both spontaneous requests from non-associated client stations and fulfill its obligations to associated client stations during assigned communication periods

Engineering Contradiction:
Improvesimplicity of response mechanismVSAvoidresponse timing delay
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent combines multiple recipient targets into a single frame structure. The access point generates a multi-recipient frame that includes both the spontaneous location determination request from a non-associated client station and data for an associated client station, allowing simultaneous delivery to multiple recipients without requiring separate transmissions

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The frame structure is designed to serve multiple functions and multiple recipients simultaneously. A single frame can carry location determination information for one recipient while also carrying data for another recipient during the same communication period, making the communication mechanism universal and adaptable to different recipient types

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If the access point transmits separate frames for each recipient, then each frame can be optimized for its specific recipient, but this increases network traffic and power consumption

Engineering Contradiction:
Improveframe optimization for specific recipientVSAvoidpower consumption and network traffic
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

Multiple frames that would otherwise be transmitted separately are merged into a single multi-recipient frame. This consolidation reduces the total number of transmissions required, thereby reducing network traffic and the power consumption associated with both transmission and reception operations

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The multi-recipient frame structure serves multiple recipients simultaneously, making the single frame transmission equivalent to multiple optimized transmissions in terms of information delivery, while reducing the overhead of multiple separate transmission cycles

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If the access point delays responding to spontaneous location determination requests to fulfill assigned communication periods, then obligations to associated client stations are met, but spontaneous location determination is delayed and power consumption increases

Engineering Contradiction:
Improvefulfillment of communication obligationsVSAvoidpower consumption during delays
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The access point merges the spontaneous location determination response with the scheduled communication data into a single transmission during the assigned communication period. This eliminates the need to delay either response, as both are delivered simultaneously in the same time window

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The access point prepares the multi-recipient frame in advance during the assigned communication period, incorporating both the spontaneous request response and the scheduled data. This preliminary preparation ensures that when the communication period arrives, the access point can fulfill both obligations immediately without delay

Inventive Principle:
Principle #10Preliminary action

AI summary

The present disclosure describes methods and apparatus for enabling spontaneous location determination in a scheduled wireless communication environment. For example embodiments, a first wireless communication device includes a transceiver and a multiple recipient communication system. The transceiver is configured to receive from a second wireless communication device a request to participate in a location determination procedure (LDP) that is to occur at least partially during a communication period that is assigned to a third wireless communication device. The multiple recipient communication system is configured to generate a multiple recipient frame that encapsulates (i) data that is destined for the third wireless communication device and (ii) a response to the request to participate in the LDP. For other example embodiments, a multiple recipient communication system of the second wireless communication device is configured to extract the response to the request to participate in the LDP from the multiple recipient frame.
