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: 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 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: Provided herein are method and apparatus for configuration of a Reference Signal (RS) and a Tracking Reference Signal (TRS). An embodiment provides an apparatus for an access node including a radio frequency (RF) interface; and processing circuitry configured to: determine a time density of a Tracking Reference Signal (TRS) based on a subcarrier spacing of a bandwidth part (BWP) in a current component carrier for a user equipment (UE); determine a frequency density of the TRS based on a bandwidth of the TRS; determine a quasi co-location (QCL) relationship of the TRS; and encode the TRS based on at least one of the time density, the frequency density and the QCL relationship for transmission to the UE via the RF interface. At least some embodiments allow for beam management, and allow for fine time and/or frequency offset tracking.

Abstract: Systems and methods of beam reporting for multiple DL processes are described. A UE receives a beam management processes configuration that provides information about beam management reference signals for beam management procedures. The UE transmits a UE capability report that indicates beam management capabilities of the UE and, later, an indication of whether the UE intends to engage in beam refinement. The UE measures the beam management reference signals and receives a beam reporting message that indicates at least one of the beam management procedures to report. In response, the UE transmits the beam report. The beam report contains beam management reference signal measurements of the beam management procedures indicated by the beam reporting message.

Abstract: An apparatus configured to be employed in a victim transmission reception point (TRP) associated with a new radio (NR) communication system is disclosed. The apparatus comprises a memory interface and a processing circuit. In some embodiments, the processing circuit is configured to process one or more predefined interference signals respectively received from one or more interfering TRPs during a guard period of the victim TRP. In some embodiments, the guard period comprises a time period between a downlink (DL) transmission and an uplink (UL) transmission associated with a time division duplex (TDD) frame of the victim TRP. In some embodiments, the processing circuit is further configured to determine an inter-TRP interference based on the one or more predefined interference signals. In some embodiments, the inter-TRP interference comprises a measurement of a UL interference at the victim TRP from the one or more interfering TRPs.

Abstract: Provided herein are a method and an apparatus for interference measurement using a beam management reference signal (BM-RS). The disclosure provides an apparatus for a user equipment (UE), comprising circuitry configured to: decode one or more beam management reference signals broadcasted by a Transmission Reception Point (TRP) in a cell, wherein the one or more beam management reference signals are used by the TRP to perform beam management for respective one or more other UEs in the cell; and measure interference from the one or more other UEs in the cell based on the decoded one or more beam management reference signals. According to some embodiments, the overhead for the interference measurement can be reduced since it is not necessary to allocate a separate CSI-RS for the purpose of interference measurement.
