UTILIZING PADDING DURATION AT START OF A HALF SUBFRAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18162826 titled 'UTILIZING PADDING DURATION AT START OF A HALF SUBFRAME

Simplified Explanation

Explanation

The patent application describes a method for optimizing the use of time domain resources in a wireless network. It suggests utilizing the padding duration at the start of every half subframe for other purposes, rather than wasting it. This can be done by transmitting a shorter single carrier symbol during the padding duration or by adapting the transmit power or receive gain for signals with different power levels.

  • The frame structure in a wireless network includes a padding duration at the start of every half subframe.
  • The padding duration is usually unused and is meant to ensure that an integer number of symbols fit within the half subframe duration.
  • The patent suggests using the padding duration for other purposes to avoid wasting time domain resources.
  • One possible use is transmitting a single carrier symbol with a shorter length than a full symbol associated with a subcarrier spacing.
  • Another use is adapting the transmit power or receive gain when a wireless node transmits or receives a signal in the first symbol of a half subframe with a different power level than the preceding symbol.

Potential Applications

  • This technology can be applied in wireless networks to optimize the use of time domain resources.
  • It can improve the efficiency of data transmission by utilizing the padding duration for other purposes.
  • The method can be implemented in various wireless communication systems, such as 5G networks, to enhance performance and resource utilization.

Problems Solved

  • The patent addresses the issue of wasting time domain resources in wireless networks.
  • By utilizing the padding duration for other purposes, the method solves the problem of inefficient resource allocation.
  • It also solves the problem of adapting transmit power or receive gain for signals with different power levels in a half subframe.

Benefits

  • The method allows for better resource utilization in wireless networks.
  • It improves the efficiency of data transmission by utilizing the padding duration effectively.
  • By adapting transmit power or receive gain, the method can optimize signal reception and transmission in different power level scenarios.


Original Abstract Submitted

In a wireless network, a frame structure may include a padding duration at the start of every half subframe to ensure that an integer number of symbols fit within a duration of the half subframe. In some aspects, to avoid wasting time domain resources, the padding duration may be utilized for other purposes. For example, because a single carrier waveform is not bound to a fixed Fast Fourier Transform size, a wireless node may use the padding duration to transmit a single carrier symbol that has a shorter length than a full symbol associated with a subcarrier spacing. Additionally, or alternatively, in cases where a wireless node is configured to transmit or receive a signal in a first symbol of a half subframe that is associated with a different power level than a preceding symbol, the padding duration may be used to adapt a transmit power or a receive gain.
