Abstract: Provided herein are method and apparatus for beam recovery. It provides an apparatus for a UE (101) including a radio frequency (RF) interface; and processing circuitry configured to: determine beam quality for one or more BPLs between the UE (101) and an access node (111,112); and in response to the beam quality for all of the BPLs being below a first predetermined threshold, encode Physical Random Access Channel (PRACH) data to include a beam recovery request that identifies a candidate beam of the access node (111,112); determine a transmit power for the beam recovery request; and send the PRACH data to the RF interface for transmission to the access node (111,112) with the transmit power. At least some embodiments allow for determining a transmission power to transmit a PRACH, to ensure reception of the PRACH, and allow for determining whether to use a PRACH or a PUCHH.

Abstract: Embodiments of the present disclosure describe apparatuses, systems, and methods for initialization of pseudo noise (PN) sequences for reference signals and data scrambling. Some embodiments may be to initialize the first M-sequence of the PN sequence with a fixed value; and initialize the second M-sequence of the PN sequence with a compressed value. Some embodiments may be to initialize the first M-sequence of the PN sequence with a fixed value; initialize the second M-sequence of the PN sequence with a part of the initialization parameters; and shift the PN sequence by another part of the initialization parameters. Some embodiments may be to initialize the first M-sequence of the PN sequence with a part of the initialization parameters; and initialize the second M-sequence of the PN sequence with another part of the initialization parameters. The embodiments may lead to a more efficient hardware design.

Abstract: Embodiments of an eNB to operate in accordance with a coverage enhancement mode are disclosed herein. The eNB may comprise hardware processing circuitry to, during a legacy sub-frame, transmit a system information block (SIB) in legacy SIB frequency resources according to a legacy SIB transmission format and refrain from transmission of channel state information reference signals (CSI-RS). The hardware processing circuitry may be further to, during a first coverage enhancement sub-frame, transmit a first portion of the SIB in first SIB frequency resources included in the legacy SIB frequency resources. The hardware processing circuitry may be further to, during a first coverage enhancement sub-frame, transmit a first set of CSI-RS in first CSI-RS frequency resources that include at least a portion of the legacy SIB frequency resources.

Abstract: Embodiments of a Generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may map data symbols to resource elements (REs) of virtual resource blocks (VRBs). The gNB may interleave the data symbols, on a per-VRB basis, to spatial layers of a multi-layer multiple-input multiple-output (MIMO) transmission. The data symbols may be interleaved based on different interleave patterns of VRB indexes for the spatial layers. The gNB may map the interleaved data symbols of the spatial layers to REs of physical resource blocks (PRBs) for orthogonal frequency division multiplexing (OFDM) transmission.

Abstract: Technology for a next generation node B (gNB), operable to use phase tracking reference signals (PT-RS) is disclosed. The gNB can identify a modulation and coding 5 scheme (MCS) for the UE for a bandwidth part (BWP) with a subcarrier spacing (SCS). The gNB can select a time density of the PT-RS based on the MCS. The gNB can select a frequency density of the PT-RS based on an allocated bandwidth in the BWP. The gNB can encode the time density and the frequency density, for the PT-RS for transmission to the UE in higher layer signaling.

Abstract: Methods, apparatuses, and systems are described related to interference averaging to generate feedback information. In embodiments, an evolved Node B (eNB) may transmit an feedback management message to a user equipment (UE) that defines one or more PRB sets. The PRB sets may include at least one PRB of the channel. The UE may average interference measurements within the PRB set and may generate channel state information (CSI) feedback for the PRB set based on the average interference measurement. The UE may transmit the CSI feedback to the eNB.
