Abstract: When performing a contention protocol, such as Listen-Before-Talk (LBT), an Long Term Evolution (LTE)-Licensed Assisted Access (LAA) node dynamically adapts the ED threshold used by the LTE-LAA node depending on whether other transmission nodes are detected at the frequency components that are to be used by the LTE-LAA node. In one implementation, the ED threshold value may initially be set to a conservative value, and when other transmissions nodes are not detected, the ED threshold value may be set to a more aggressive value. In another implementation, the ED threshold value may initially be set to a more aggressive value, and only when another transmission node is detected, the ED threshold value may be set to a more conservative value. In yet another possible implementation, the ED threshold value and the transmit power may be proportionally modified, for a particular UE, based on a parameter associated with the UE.

Abstract: Spectrum reservation circuitry for use in a source electronic device (e.g. eNB or UE) of a wireless communication system is provided. The availability of an unlicensed carrier for use is checked by control circuitry of the source device and a License Assisted Access (LAA) Request to Send signal is transmitted on an unlicensed carrier if it is determined to be available for use. Receive circuitry is configured to receive on an unlicensed carrier, from a destination electronic device an LAA Clear to Send signal in response, depending upon availability of the unlicensed channel at the destination. Corresponding spectrum reservation circuitry is provided for use in a destination device, comprising transmit circuitry to transmit the LAA Clear to Send signal. A corresponding computer program product is provided on a non-transitory medium.

Abstract: Disclosed in some examples are systems, machine-readable media, methods, and cellular wireless devices which implement a Listen Before Talk (LBT) access scheme for a device operating according to a cellular wireless protocol in an unlicensed channel. A cellular wireless device may utilize the cellular wireless protocol in the unlicensed channel after the LBT access scheme has determined that a channel (a defined range of frequencies) in the unlicensed channel is idle for a particular period of time.
