Embodiments of a Machine Type Communication User Equipment (MTC UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The MTC UE may determine a system timing based on reception of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The MTC UE may receive, from the gNB, radio resource control (RRC) signaling that indicates one or more parameters of a configurable resynchronization signal (RSS). The RSS may be for resynchronization, by the MTC UE, after the MTC UE awakens from a power save mode. The parameters of the RSS in the RRC signaling may depend on a target coverage of the MTC UE. The MTC UE may determine an updated system timing based on reception of the RSS.

Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.

Provided herein are method and apparatus for channel coding in the fifth Generation (5G) New Radio (NR) system. An embodiment provides an apparatus for a Next Generation NodeB (gNB), including circuitry, which is configured to: generate Downlink Control Information (DCI) payload for a NR-Physical Downlink Control Channel (NR-PDCCH); attach Cyclic Redundancy Check (CRC) to the DCI payload; mask the CRC with an Radio Network Temporary Identifier (RNTI) using a bitwise modulus 2 addition operation, wherein the number of bits for the RNTI is different from the number of bits for the CRC; and perform polar encoding for the DCI payload with the masked CRC.

An enhanced NodeB (eNB), user equipment (UE) and method of Channel State Information (CSI) measurement and reporting using reduced bandwidth are generally described herein. The UE is preconfigured with a resource configuration information or the configuration information is transmitted to the UE from the eNB. The configuration information indicates a narrowband region on which to monitor for and receive physical downlink control and data channels and perform measurements for CSI computation. The region has a reduced bandwidth that is supported by the UE and is free from subbands outside of the region. The UE takes measurements of downlink transmissions using the assigned resources. The measurements are limited to subbands included within the region. The UE calculates the CSI based on an unrestricted time interval within subframes of the region and a restricted frequency interval free from physical resource blocks outside the region. The UE reports a region-specific wideband CSI that includes at least a region-specific wideband Channel Quality Indicator to the eNB.

Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The gNB may encode multiple candidate code-block groups to be available for a transmission in unlicensed spectrum, wherein one of the candidate code-block groups is to be transmitted based on a listen-before-talk (LBT) process. Each of the candidate code-block groups may be mapped to a different subset of channels in the unlicensed spectrum. The gNB may determine, based on one or more channel measurements, one or more of the channels that are available for the transmission. The gNB may select, as the candidate code-block group to be transmitted, a candidate code-block group for which the subset of the channels that is mapped to the selected candidate code-block group is included in the one or more channels that are available for the transmission.

An eNodeB (eNB), user equipment (UE) and method for operating in enhanced coverage (EC) modes are generally described. The UE may receive one or more physical broadcast channel (PBCH) signals, dependent on whether the UE is in a normal coverage mode or in one of the EC modes. The PBCH signal may be combined to form a combined PBCH signal, when the UE is in an EC mode, and decoded to determine one of a plurality of sets of resource regions associated different EC modes for communication with the eNB. The signal may be scrambled using a Radio Network Temporary Identifier (RNTI) dependent on at least one of a signal type of the control signal and the EC mode. Paging and the system information block (SIB) signals in a Physical Downlink Shared Channel (PDSCH) may be decoded without decoding a physical downlink control channel (PDCCH) signal associated with the PDSCH.

Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH), wherein a cyclic redundancy check (CRC) of the PDCCH is scrambled by a radio network temporary identifier (RNTI). In some cases, if the RNTI that scrambles the PDCCH is a modulation coding scheme (MCS) cell RNTI (MCS-C-RNTI), cell RNTI (C-RNTI), or a configured scheduling RNTI (CS-RNTI), the UE may determine that: one or more PT-RSs are present in the PDSCH, a time density parameter of the PT-RSs is equal to one, and a frequency density of the PT-RSs is equal to two.
摘要:
Embodiments of a Next Generation Node-B (gNB) and User Equipment (UE) are generally described herein. The gNB may transmit control signaling to configure transmission of position reference signals (PRSs) by a plurality of transmit-receive points (TRPs). The gNB may receive, from the UE, for each of the TRPs, a set of signal location parameters (SLPs). The gNB may perform an iterative process to estimate a position of the UE. For a current iteration, the gNB may: determine a current estimate of the position of the UE based on a current plurality of sets of SLPs; and determine a cost function for each of the current plurality of sets of SLPs. The gNB may determine, based on the cost functions, a next plurality of sets of SLPs for a next estimate of the position of the UE.
