TRANSMISSION OF DIFFERENTIAL BROADCAST POSITIONING SIBS FOR REDUCED POWER CONSUMPTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17999381 titled 'TRANSMISSION OF DIFFERENTIAL BROADCAST POSITIONING SIBS FOR REDUCED POWER CONSUMPTION

Simplified Explanation

The patent application describes a method for encoding and broadcasting positioning assistance data (PAD) in a differential manner by a base station. The PAD is encoded in positioning System Information Blocks (posSIBs) and periodically broadcasted.

  • PAD that is different from previously broadcasted PAD is encoded separately in a block of posSIB.
  • PAD that remains unchanged is also encoded separately in another block of posSIB.
  • A block of posSIB includes reference encoding that identifies the changed PAD and provides scheduling information.
  • A UE (User Equipment) can decode the reference encoding to determine if it has previously received the changed PAD.
  • If the UE has received the PAD before but not the new or changed PAD, it can receive and decode the block of posSIB with only the changed PAD, increasing efficiency.

Potential Applications

  • This technology can be applied in cellular networks to improve the efficiency of broadcasting positioning assistance data.
  • It can be used in location-based services to enhance the accuracy and reliability of positioning information.

Problems Solved

  • The technology solves the problem of inefficient broadcasting of positioning assistance data by encoding and broadcasting only the changed PAD separately.
  • It addresses the issue of unnecessary decoding of unchanged PAD by providing reference encoding to identify the changed PAD.

Benefits

  • The method increases the efficiency of broadcasting positioning assistance data, reducing the amount of data that needs to be transmitted.
  • It improves the decoding efficiency for User Equipment by allowing them to receive and decode only the changed PAD.
  • The technology enhances the accuracy and reliability of positioning information, benefiting location-based services.


Original Abstract Submitted

Positioning assistance data (PAD) is encoded in positioning System Information Blocks (posSIBs) and periodically broadcast by abase station in a differential manner A PAD element that is different relative to previously broadcast PAD is encoded in a block of posSIB separately from PAD that is unchanged. Another separate block of posSIB includes reference encoding identifying the changed PAD and provides scheduling information. A UE may decode the reference encoding and determine whether the UE has previously decoded the changed PAD. If the UE has previously received the PAD, but has not yet received the new or changed PAD, the UE may receive and decode the block of posSIB with only the changed PAD, thereby increasing efficiency.
