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

This abstract first appeared for US patent application 17668242 titled 'MULTI-DEVICE SYNCHRONIZATION AND DATA TRANSMISSION

Simplified Explanation

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) devices.

  • The first UE exchanges data with the second UE on a side channel before sending it to the network.
  • Both UEs transmit the data to the network using their transmit antennas, increasing the transmission power.
  • The second UE may transmit a modified version of the data to improve signal-to-noise ratio through transmit diversity.
  • To prevent unintended beamforming, the network mixes signals received at different sub-carriers or different time periods.
  • The network provides a phase correction value to the UEs based on the received signals, allowing them to adjust their transmissions accordingly.

Potential Applications

  • This technology can be applied in various wireless communication networks, such as cellular networks, Wi-Fi networks, or satellite communication systems.
  • It can improve the overall signal quality and coverage in areas with weak network signals or high interference.
  • The method can be used to enhance data transmission in crowded environments with multiple UEs, such as stadiums, concert venues, or conference centers.

Problems Solved

  • Weak network signals and interference can lead to poor signal quality and limited coverage, affecting the performance of communication networks.
  • Beamforming, where signals are focused in a specific direction, can unintentionally occur and cause interference or signal degradation.
  • Transmit diversity can help improve signal-to-noise ratio, but it requires coordination between UEs and the network.

Benefits

  • By utilizing the side channel and combining the transmission power of multiple UEs, the overall signal strength and coverage can be significantly improved.
  • Transmit diversity enhances the signal quality, leading to better data transmission and reception.
  • The method helps avoid unintended beamforming, reducing interference and maintaining signal integrity.
  • The phase correction value provided by the network allows UEs to adjust their transmissions accurately, further improving signal quality.


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.
