Abstract: Devices and methods of simultaneous data reception and measurement are generally described. A UE transmits to an eNB antenna capacity and receives a Beamformed Reference Signal (BRS) configuration in response. Beamformed signals from the eNB include a BRS subframe in accordance with the BRS configuration. The BRS subframe has a BRS whose structure depends on the UE antenna capacity. If the UE has a single antenna panels, neither an EPDCCH nor a PDSCH for the UE is in the BRS frame. If the UE has a single antenna panels and multiple ports or multiple antenna panels, the BRS may contain an EPDCCH or PDSCH for the UE as different ports or antenna panels may be assigned different functionality. The UE measures BRS Received Power (BRS-RP) of the BRS, transmits a BRS report based on the BRS-RP and selects an optimal beam based on BRS-RPs from BRSs of the beams.

Abstract: Disclosed herein are apparatuses, systems, and methods for reference signal design for initial acquisition, by receiving a first primary synchronization signal (PSS) and a first secondary synchronization signal (SSS) from a first transmit (Tx) beam, in first contiguous orthogonal frequency division multiplexing (OFDM) symbols of a downlink subframe. A UE can receive at least a second PSS and a second SSS from a second Tx beam in contiguous OFDM symbols of the downlink subframe. A UE can then detect beamforming reference signals (BRSs) corresponding to the first Tx beam and the second Tx beam, based on identification of physical cell ID information and timing information processed from the first PSS, the second PSS, the first SSS, and the second SSS. The UE can select the first Tx beam or the second Tx beam that was received with the highest power, based on the BRSs. Other embodiments are described.

Abstract: An enhanced NodeB (eNB), user equipment (UE) and method of communicating using Long Term Evolution (LTE) licensed and unlicensed bands are generally described herein. The eNB may transmit a trigger signal to the UE. The trigger signal may be transmitted in the LTE unlicensed or licensed band and inform the UE of transmission of a reference signal from the eNB to the UE in the unlicensed band. The trigger signal may correspond to a single reference signal transmission or multiple periodic or consecutive reference signal transmissions. The trigger signal or a separate trigger signal may be used to inform the UE of a data transmission. The trigger signal may be transmitted at any point prior to or in the same subframe as the reference signal and the reference signal may be transmitted before, after or in the same subframe as the data.

Abstract: Embodiments of a User Equipment (UE), an Evolved Node-B (eNB), small-cell access point (AP), and methods for dynamic millimeter wave pencil cell communication are generally described herein. The UE may receive access point reference signals (APRS) from one or more small-cell access points (AP), and may transmit APRS signal quality measurements to a macro-cell Evolved Node-B (eNB). The UE may receive, from the macro-cell eNB, a message that indicates candidate pencil cells for which the UE is to determine signal quality measurements, the candidate pencil cells supported by the small-cell APs. The UE may receive beam reference signals (BRS) for the candidate pencil cells and may refrain from reception of BRS for pencil cells not included in the message. In some cases, beam-widths of the APRSs may be larger than beam-widths of the BRSs.

Abstract: Systems, methods, and devices for device-to-device (D2D) distributed scheduling are disclosed herein. User equipment (UE) is configured to measure a received power level for a reference signal received from a target UE and measure received power levels for reference signals received from one or more non-target UEs. The UE is configured to generate a resource usage map for the target UE and the one or more non-target UEs. The UE is configured to determine a priority, with respect to the target UE, for each resource element group based on the resource usage map and an anticipated signal-to-interference ratio (SIR). The UE is configured to transmit data to the target UE during one or more resource element groups with the highest priorities for the target UE.

Abstract: A user equipment (UE) is configured to receive a maximum probability of accessing a wireless local area network (WLAN) for communication. The maximum probability is received via a 3rd Generation Partnership Project (3GPP) communication link with an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). The UE is further configured to determine that there is a queued transmission for the UE and, in response to determining that there is a queued transmission, to determine whether the UE is authorized to access to the WLAN using a probability less than or equal to the maximum probability. The UE is further configured to delay contention for access to the WLAN for at least a pre-backoff duration in response to determining that the UE is not authorized.

Abstract: Technology described herein addresses symmetric uplink (UL)/downlink (DL) designs that can be applied to both uplink and downlink transmissions. A symmetric UL/DL design can define a Transmission Time Interval (TTI) format with control channels and data channels multiplexed using Frequency Division Multiplexing (FDM) or Time Division Multiplexing (TDM) to partition the control channels and the data channels within a Transmission Time Interval (TTI). A unified waveform can be applied to both UL and DL transmissions. Several Demodulation Reference Signal (DM-RS) designs are also described. A hybrid mode for UL transmissions is also described.

Abstract: Technology for efficient distributed scheduling is provided using tentative grants. A UE can receive a transmission request from a Tx UE, and from additional Tx UEs. Each Tx request can include a priority level of the transmitter UE sending the transmission request, to form a priority list. An incompatible list can be formed based on a signal to interference ratio of each transmitter with the UE. A grant message and the incompatible list can be transmitted for n−1 iterations from selected UEs based on the priority list and incompatible list. A tentative bandwidth grant can then be transmitted at an nth iteration to tentatively allow the transmitter UE to send a D2D communication to the UE in the bandwidth grant.
