Problems solved by technology

The main limitation is the threshold of the energy level on the channel that the device must listen to to decide if it can transmit
The lower the energy detection threshold used, the less likely it is to conclude that the channel is operating freely through the LBT process

Abstract

A method for performing a listen-before-talk procedure in a first transceiver device (N1) for wireless electromagnetic communication in a frequency band (150) is disclosed. A first transceiver device (N1) configured to perform the method is also disclosed. The method comprises receiving at the first transceiver device (N1) a stream of data (11) from a second transceiver device (N2), and determining whether the second transceiver device (N2) is capable of receiving in only a single or in two polarization directions. If the second transceiver device (N2) is capable of receiving in two polarization directions, then the method comprises determining and using an energy threshold that is larger than a regulated energy threshold for listen-before-talk within the frequency band (150). If the second transceiver device (N2) is capable of receiving in only a single polarization direction or if the energy of the received stream of data (11) is smaller than the energy threshold, then constructing a signal to be transmitted within the frequency band (150) by the first transceiver device (N1).

Description

[0001] The present disclosure relates to methods and devices for enhancing wireless radio communications on unlicensed frequency bands. Background technique [0002] The invention relates to radio transmissions on license-exempt frequency bands. When communicating on a license-exempt frequency band, it is usually necessary to perform a Clear Channel Assessment (CCA), which is commonly referred to as a Listen-Before-Talk (LBT) procedure. LBT is a mechanism that can be used to efficiently share a common spectrum among multiple wireless local area network (LAN) devices whereby a transmitter first senses its environment before starting to transmit. LBT can be used by a device to find out whether a channel, band or spectrum is free to operate. The main limitation is the threshold of the energy level on the channel that a device must listen to to decide whether it can transmit. The lower the energy detection threshold used, the less likely it is to conclude that the channel is ope...
