Partial Radio Block Polling for Wireless Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems require mobile stations to continuously monitor all assigned radio blocks for data, leading to increased power consumption and inefficient resource allocation, as they must decode every radio block to determine if it contains information intended for them, and existing systems do not allow for flexible or partial resource assignments.
Innovation Solution
Implementing partial packet assignments that allow networks to allocate non-consecutive radio blocks to mobile stations, enabling them to only decode and process assigned blocks, reducing unnecessary monitoring and power consumption, and allowing resource address reuse among different stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile stations continuously monitor all assigned radio blocks to ensure reliable data reception, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent segments the continuous monitoring requirement into discrete polling events. Instead of monitoring every radio block, the network sends periodic polling messages that selectively query specific mobile stations about their data reception status. This segmentation allows mobile stations to transition between active monitoring and low-power states, reducing overall power consumption while maintaining reliable data transfer through targeted polling interactions.
2Measurement precision
If mobile stations decode every radio block to determine if it contains their data, then data detection accuracy is improved, but processing time and energy increase
Solution Approach 1:
The patent implements preliminary action through network-side polling before mobile stations decode radio blocks. The network sends polling messages that contain advance information about which mobile stations have data available. This preliminary notification allows mobile stations to skip decoding radio blocks that don't contain their data, maintaining detection accuracy while significantly reducing processing time and energy consumption.
3Adaptability or versatility
If networks allocate resources to all mobile stations in each radio block period, then resource availability is improved, but resource allocation efficiency decreases
Solution Approach 1:
The patent implements dynamic resource allocation through periodic polling mechanisms. Instead of static allocation where all mobile stations receive resources in every radio block period, the network dynamically adjusts resource allocation based on actual data transfer needs. The polling messages selectively activate resources for specific mobile stations that have data to send or receive, improving overall resource allocation efficiency while maintaining the flexibility to adapt to changing traffic conditions.

AI summary
Example methods and apparatus to poll in wireless communications are disclosed. A disclosed example method involves receiving a poll from a network during a first radio block period and identifying a resource for use in sending requested information to the network in response to the poll. The resource occurs during a subsequent radio block period, and the identifying of the resource is based on receipt of an uplink allocation indicator. The example method also involves transmitting a response to the poll.
