Abstract:
Described is an Evolved Node-B (eNB) to communicate with one or more User Equipment (UEs) on a Long Term Evolution (LTE) network operating in an unlicensed spectrum, the eNB comprising hardware processing circuitry including: an antenna; and a transmitter, coupled to the antenna, the transmitter operable to: inhibit transmission of system information to a UE when the spectrum is unlicensed. The transmitter may also be operable to: refrain from transmission of one or more synchronization signals to a UE when a spectrum is unlicensed. The transmitter may also be operable to transmit the one or more synchronization signals in frequencies away from the centers of the six PRBs of the transmission bandwidth. The transmitter may also be operable to: turn off transmitting in the unlicensed spectrum when the eNB is not servicing any UE; and turn on transmitting in the unlicensed spectrum when a UE is discovered.

Briefly, in accordance with one or more embodiments, a conventional physical downlink control channel (PDCCH) is transmitted in a first region of a physical downlink control channel structure utilized by a remote radio head that has been assigned a cell identifier that is common to one or more other remote radio heads within the cell, and an enhanced physical downlink control channel (ePDCCH) is transmitted in a second region of the physical downlink control channel structure.
Abstract:
Communication signals using a first and a second frequency band in a wireless network is described herein. The first frequency band may be associated with a first beamwidth while the second frequency band may be associated with a second beamwidth, the first beamwidth being wider than the second beamwidth. The first frequency band may be used to communicate first signals to facilitate initial communication, including signals and/or control information to coarsely configure a receiving device. The second frequency band may then be used to communicate second signals that facilitate further communication, including signals and/or control information for finer configuring of the receiving device. Alternatively, the first and second frequency bands may be used in a wireless network to communicate a first and a second signals independently.

Abstract:
Embodiments of the present disclosure include methods and apparatuses, for a third generation partnership project (3GPP) enhanced NodeB (eNB) to transmit parameters of a wake-up procedure with a 3GPP user equipment (UE). After the transmission, the eNB may enter a low power state wherein it monitors for the wake-up signal from the UE, the wake-up signal being based at least in part on the transmitted parameters of the wake-up procedure. When the eNB receives the wake-up signal, the eNB may enter the high-power state and transmit a connection establishment signal to the UE.
