Abstract: Techniques, apparatus and methods are disclosed that enable reduced signaling overhead in a fifth generation (5G) wireless system. The system includes support for asynchronous uplink transmission, resource pool configuration, acknowledgement response and retransmission. For example, in a Type-1 transmission scheme, a user equipment (UE) selects one resource within the resource pool and transmits data in the uplink on the selected resource. In a Type-2 transmission scheme, a UE selects one resource within a scheduling request (SR) region in the resource pool, transmits the SR for the resource which contains the resource allocation for data transmission, and transmits the uplink data on the resource which is indicated in the SR information. In a Type-3 transmission scheme, a UE selects a resource within the SR region, transmits the SR on the selected resource with information on the resource selected for subsequent data transmission and transmits on the indicated resource if it receives an acknowledgment, in response to its transmitted SR.

Abstract: Technology to improve resource allocation for inter-cell device-to-device (D2D) discovery and timing synchronization between user equipments (UEs) connected to asynchronous network deployments is disclosed. Also, transmission rules are provided for networks wherein discovery-resource pools are allocated in a frequency-division-multiplexing (FDM) manner. In the first sub-frame of a transmission-resource pool, there may be overlap between resources that are allocated for a discovery-resource pool and resources that are allocated for D2D synchronization signals (D2DSSs). Non-overlapping PRBs in the discovery-resource pool can be allocated for WAN transmission or D2D-discovery transmission. In scenarios where discovery-resource pools are allocated using FDM, a measurement such as reference signal received power (RSRP) or path loss can be made for a UE. The measurement can be compared to a threshold value to determine whether the UE will transmit a D2DSS.

Abstract: User equipment (UE) can include processing circuitry configured to decode radio resource control (RRC) signaling from a base station, the RRC signaling indicating a transmission coding scheme for a physical uplink shared channel (PUSCH) transmission. PUSCH-to-phase tracking reference signal (PT-RS) energy per resource element (EPRE) ratio is determined using the RRC signaling. A PT-RS power boosting factor is determined based on the transmission coding scheme and the PUSCH-to-PT-RS EPRE ratio. The PT-RS is encoded for transmission using a plurality of PT-RS symbols, the transmission using increased transmission power corresponding to the PT-RS power boosting factor. The RRC signaling further includes a flag enabling the PT-RS transmission. The PUSCH-to-PT-RS EPRE ratio is 00 or 01, and the transmission coding scheme is a codebook-based uplink transmission or non-codebook-based uplink transmission.

Abstract: Technology for a user equipment (UE) operable to perform device to device (D2D) discovery in a wireless network is described. The UE can decode D2D discovery parameters received from an eNodeB. The UE can determine a UE D2D discovery resource from the D2D discovery resource allocation based, in part, on the D2D discovery parameters. The UE can encode a D2D discovery message for transmission from the UE to a second UE using the UE D2D discovery resource in the D2D discovery resource allocation.

Abstract: Methods and architectures for establishing an uplink control channel in a fifth generation (5G) or new radio (NR) wireless network includes transmitting scheduling requests (SRs) at sub-slot level/symbol-level periodicities and determining whether SR transmit opportunities will collide with downlink (DL) signals being received and halting an SR transmission if the timing of DL symbols overlap at an OFDM symbol with the SR transmission.

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.
