MULTI-DEVICE SYNCHRONIZATION AND DATA TRANSMISSION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18483916 titled 'MULTI-DEVICE SYNCHRONIZATION AND DATA TRANSMISSION

Simplified Explanation

The abstract of the patent application describes a method for improving the transmission power and signal quality in a communication network by utilizing a side channel between two user equipment (UE). The UEs exchange data, and then transmit the data to the network using the transmit antennas of both UEs, instead of just one. The second UE may transmit a variation of the data sent by the first UE to improve the signal-to-noise ratio. To avoid unintended beamforming of the transmissions, the network mixes signals received at different sub-carriers or at different time periods. The network also notifies the UEs of a phase correction value based on the signals, which the UEs can use to adjust their transmissions.

  • The UEs exchange data on a side channel before transmitting to the network.
  • Both UEs use their transmit antennas to increase the transmission power.
  • The second UE may transmit a variation of the data to improve signal quality.
  • The network mixes signals to avoid unintended beamforming.
  • The network provides a phase correction value to the UEs for transmission adjustment.

Potential applications of this technology:

  • Wireless communication networks
  • Cellular networks
  • Internet of Things (IoT) devices
  • Satellite communication systems

Problems solved by this technology:

  • Low transmission power and signal quality in wireless communication
  • Limited coverage and range of communication networks
  • Interference and noise in signal transmission

Benefits of this technology:

  • Improved transmission power and signal quality
  • Increased coverage and range of communication networks
  • Enhanced reliability and performance of wireless communication systems
  • Reduced interference and noise in signal transmission


Original Abstract Submitted

First user equipment (UE) exchanges at least a portion of data to be transmitted to a communication network with a second UE on a side channel. The UEs then send the data to the network at increased transmission power by using transmit antennas of both the first and second UEs, instead of just those of the first UE. In some cases, the second UE may transmit a variation of the data sent by the first UE to perform transmit diversity and improve signal-to-noise ratio. To avoid unintended beamforming of the transmissions, the network may mix signals (e.g., having a same symbol) received at the same time period but at different sub-carriers, or mix the signals received at different time periods but at the same sub-carrier. The network may notify the UEs of a phase correction value based on the signals, and the UEs may adjust using the phase correction value.
