Abstract: Technology for a Next Generation NodeB (gNB) operable to encode a primary synchronization signal for transmission to a user equipment (UE) is disclosed. The gNB can identify a sequence d(n) for a primary synchronization signal. The sequence d(n) can be defined by: d(5 n)=1.2s(n), where s(n) is a maximum run length sequence (msequence) and s(n) is provided as s(n+7)=(s(n +4)+s(n)) mod 2, where 0.n.127. The gNB can generate the primary synchronization signal based on the sequence d(n). The gNB can encode the primary synchronization signal for transmission to the UE.

Abstract: Technology for a user equipment (UE) operable to adjust a receiver timing is disclosed. The UE can decode a plurality of channel-state information reference signals (CSI-RSs) received from a plurality of cooperating nodes, wherein the plurality of cooperating nodes are included in a coordination set of a Coordinated MultiPoint (CoMP) system. The UE can generate a plurality of received RS timings from the plurality of CSI-RSs, wherein the received RS timings represent timings from the plurality of cooperating nodes. The UE can determine a composite received RS timing from the plurality of received RS timings. The UE can adjust the receiver timing based on the composite received RS timing.

Abstract: Embodiments of interference coordination for aerial vehicle user equipment (UE) are described. In some embodiments, a base station (BS) is configured to select a subset of time-frequency resources dedicated for use in serving aerial vehicle UEs and communicate with the aerial vehicle UEs via the subset of time-frequency resources. In some embodiments, the BS may transmit signaling to a neighbor BS that indicates the BS has dedicated the subset of time-frequency resources for serving aerial vehicle UEs and the subset of time-frequency resources to be used. The BS may receive an indication from the neighbor BS that a neighbor BS is to dedicate the subset of time-frequency resources to serve aerial vehicle UE, and based on the indication, the BS may reduce transmission activities in the subset of time-frequency resources, including refraining from transmitting or reducing an amount of information or power level of signaling to the aerial vehicle UEs.

Abstract: Systems and technologies described herein provide functionality for a cellular base station to dynamically indicate a reception (Rx) beam to be used by a user equipment (UE). The Rx beam can be indicated explicitly or implicitly. The UE can, for example, use the Rx beam for Physical Downlink Shared Channel (PDSCH) reception, Channel State Information Reference Signal (CSI-RS) measurements, and/or Channel State Information (CSI) calculation at the UE. Systems and technologies described herein are generally useful for systems that use multiple transmission (Tx) beams and/or that support Coordinated Multipoint (CoMP) transmission technology.

Abstract: Communication in a wireless network using a phase-tracking reference signal (PT-RS) for orthogonal frequency division multiplexing (OFDM) includes determining one or more PT-RS groups of adjacent subcarriers in a resource allocation for a physical uplink shared channel (PUSCH) or a physical downlink shared channel (PDSCH), encoding data to be transmitted by the PUSCH or the PDSCH in data subcarriers within the resource allocation for the PUSCH or the PDSCH, and encoding phase-tracking reference signals within the one or more PT-RS groups of adjacent subcarriers.

Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for designing quality report for enhanced Machine Type Communication (EMTC) and Narrowband Internet of Things (NB-IOT). For example, some embodiments are directed to a user equipment (UE) including radio front end circuitry and processor circuitry coupled to the radio front end circuitry. The processor circuitry can be configured to determine a downlink (DL) quality metric based on a DL quality metric type and identify a message 3 (Msg3) signal based on the determined DL quality metric. The processor circuitry can further be configured to transmit, using the radio front end circuitry, the identified Msg3 signal to a base station.

Abstract: A method for slot offset determination for non-terrestrial networks includes receiving a physical downlink control channel (PDCCH) including downlink control information (DCI) scheduling transmission of a physical uplink shared channel (PUSCH) and receiving a slot offset for transmission of the PUSCH. An additional slot offset is determined based on a timing advance value. A total slot offset is determined based on the slot offset and the additional slot offset. The PUSCH is transmitted based on the total slot offset and the timing advance value.
