Abstract: Technology for a user equipment (UE) configured for bandwidth adaptation (BWA) is disclosed. The UE can decode resource allocation information for a first radio frequency (RF) bandwidth including a primary subband available to the UE for data communication. Th 5 e UE can decode resource allocation information for a second RF bandwidth, wherein the second RF bandwidth comprises the first RF bandwidth and at least one secondary subband available to the UE for data communication. The UE can encode data for transmission to a next generation NodeB (gNB) using resources allocated for the second RF bandwidth in the primary subband and the secondary subband. The UE 10 can have a memory interface configured to send to a memory the resource allocation information for the first RF bandwidth and the second RF bandwidth.

Abstract: Systems, apparatus, user equipment (UE), evolved node B (eNB), computer readable media, and methods are described for multi-carrier listen before talk operations. In various embodiments, a transmitting device may assign one or more primary carriers to perform listen before talk (LBT) operations, with non-primary carriers performing a channel sensing operation at the end of the LBT operations of at least one primary channel. In various embodiments, the LBT operations at the primary carriers may use a shared random countdown number or an independent random countdown.

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: An enhanced NodeB (eNB), user equipment (UE) and communication methods therebetween using an unlicensed channel of an unlicensed band are generally described. The eNB measures an interference power level (IPL) of the unlicensed channel at the eNB and determine a transmit power level (TPL) for a downlink transmission based on the IPL, the TPL decreasing with increasing IPL. Feedback including unlicensed channel conditions measured by the UE is used by the eNB to determine the UE-eNB proximity. The eNB determines whether to transmit the downlink transmission to the UE based on the IPL and the proximity; as the IPL increases, the eNB services increasingly proximate UEs until, when the IPL exceeds a predetermined threshold, the eNB does not service any UE using the unlicensed channel. The eNB schedules and transmits the downlink transmission to the UE using the transmit power level.

Abstract: Embodiments described herein relate generally to a communication between a user equipment (“UE”) and an evolved Node Bs (“eNBs”) in a plurality of frequency bands. An eNB may transmit cross-carrier, cross-subframe scheduling information to a UE in a licensed frequency band. In response reception of the scheduling information, the UE may sense a wireless transmission medium to determine if the medium is idle. If the medium is idle, the UE may generate and transmit a request to reserve the medium in the unlicensed frequency band (e.g., a Clear-to-Send message). The eNB may transmit downlink data to the UE in the unlicensed frequency band. Other embodiments may be described and/or claimed.

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.
