NON-ORTHOGONAL AND ORTHOGONAL RESERVATION SIGNALS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17995943 titled 'NON-ORTHOGONAL AND ORTHOGONAL RESERVATION SIGNALS

Simplified Explanation

The abstract describes a technique for sidelink communications in an unlicensed spectrum. The method involves a first device sensing an idle unlicensed frequency band consisting of multiple subchannels. In response to this, the first device transmits a data signal or a reservation signal over one or more subchannels, reserving the unlicensed frequency band for a specific time period.

  • The technique enables communication in an unlicensed spectrum.
  • The first device senses an idle frequency band before transmitting.
  • The transmission can be either a data signal or a reservation signal.
  • The transmission reserves the frequency band for a specific time period.

Potential Applications

  • Internet of Things (IoT) devices can utilize this technique for communication in unlicensed spectrum.
  • Wireless sensor networks can benefit from this method for efficient data transmission.
  • Mobile devices can use this technique for direct communication without relying on a cellular network.

Problems Solved

  • Efficient utilization of unlicensed frequency bands by reserving them for specific time periods.
  • Avoiding interference by sensing idle frequency bands before transmission.
  • Enabling direct communication between devices without relying on a centralized network.

Benefits

  • Improved spectrum utilization by reserving idle frequency bands.
  • Enhanced reliability and efficiency of communication in unlicensed spectrum.
  • Reduced dependency on cellular networks for device-to-device communication.


Original Abstract Submitted

Certain aspects of the present disclosure provide techniques for sidelink communications in an unlicensed spectrum. A method that may be performed by a first device includes sensing that an unlicensed frequency band is idle, the unlicensed frequency band consisting of a plurality of subchannels. The method also includes, in response to sensing that the unlicensed frequency band is idle, transmitting, by the first device, at least one of a data signal or a reservation signal during an entire duration of a time period over one or more subchannels of the plurality of subchannels, the at least one of the data signal or the reservation signal reserving the unlicensed frequency band during the time period.
