Abstract:
An apparatus used in a UE includes processing circuitry and memory. To configure the UE for DMRS processing in a 5G NR network, the processing circuitry is to decode higher layer signaling indicating a DMRS type and a BARS length. DCI is decoded, which includes an antenna port value. One or more DMRS antenna ports are determined based on the DMRS type, the DMRS length, and the antenna port value. The one or more DMRS antenna ports are configured for port multiplexing using a TD-OCC or an FD-OCC. A DMRS of the DMRS type and the DMRS length is decoded. The DMRS is received via a PDSCH using the one or more DMRS antenna ports.
Abstract:
An apparatus is configured to be employed within a base station. The apparatus comprises baseband circuitry, which includes a radio frequency (RF) interface and one or more processors. The one or more processors are configured to generate channel state information reference signals (CSI-RS) for an antenna array and provide the CSI-RS to the RF interface for transmission to a user equipment (UE) device, receive one or more report matrices based on sets of measurements of the CSI-RS and from the RF interface, and generate a channel covariance matrix based on the received one or more report matrices.
Abstract:
Embodiments of an Evolved Node-B (eNB), User Equipment (UE) and methods for communication are generally described herein. The eNB may generate a plurality of adaptive codebooks based on a base codebook. Each adaptive codebook may be generated for a different beam-width for directional transmissions by an antenna array. The adaptive codebooks may be generated based at least partly on matrix products of a first matrix based at least partly on a configurable broadening factor and a second matrix that includes codewords of the base codebook. A predetermined plurality of broadening factor values may be used in the first matrix to produce the different beam-widths for the adaptive codebooks.
Abstract:
Some demonstrative embodiments include devices, systems and/or methods of inter-node communication. For example, a first node may communicate with a second node, e.g., via a backhaul link, one or more messages including a restriction recommendation and/or a restriction setting, for example, a precoding restriction, a Relative Narrowband TX Power indication (RNTP) setting, and/or a Relative Wideband Transmit Power (RWTP) setting.
Abstract:
A computer-readable storage medium stores instructions to configure a UE for enhanced phase-tracking reference signal (PTRS) transmission in a wireless network, and to cause the UE to perform operations. The operations include selecting an antenna, port of a plurality of available antenna ports. A plurality of discrete Fourier transform (DFT) spread orthogonal frequency division multiplexing (DFT-s-OFDM) symbols are generated using a randomly-generated symbol and an orthogonal cover code (OCC). The OCC is based on the selected antenna port. A pre-DFT insertion of the plurality of DFT-s-OFDM symbols is performed in time domain to generate a group-based time-domain PTRS. Uplink data is encoded for transmission to a base station, the uplink data including the group-based time-domain PTRS.
Abstract:
Channel state information (CSI) feedback of common CSI components is discussed. An example user equipment (UE) includes a receiver circuit, processor, and transmitter circuit. The receiver circuit is configured to receive CSI configuration information for a plurality of downlink (DL) cells that indicates a first group of two or more of the DL cells and at least one CSI component designated for common reporting for the first group. The processor is configured to calculate a group value for each of the at least one CSI components designated for common reporting for the first group and selectively calculate, for each DL cell of the first group, individual values for any CSI components not designated for common reporting for the first group. The transmitter circuit is configured to transmit the group value for each of the designated CSI components and the individual values for any additional CSI components.
Abstract:
In providing feedback to an eNB in an LTE network for downlink scheduling and link adaptation, a UE issues a channel state information (CSI) report that includes a channel quality index (CQI). The reported CQI should include all UE receiver processing capabilities, including NAICS (network assisted interference cancellation and suppression) capability to cancel and suppress interference. Described are measures that may be taken to provide more accurate reporting of CSI by a terminal with NAICS capability.
Abstract:
Generally, this disclosure provides devices, systems and methods for subframe restricted Channel State Information (CSI) reporting with Rank Indicator (RI) inheritance. A User Equipment (UE) device may include an RI generation module to generate RIs based on a received CSI configuration from an evolved Node B (eNB) of a serving cell of the UE. The UE may also include an RI Reference Process CSI generation module to generate a first Reference CSI including a first selected RI of the generated RIs, the first selection based on a first subframe set of the received CSI configuration, and to generate a second Reference CSI including a second selected RI of the generated RIs, the second selection based on a second subframe set of the received CSI configuration. The UE may further include a Linked Process CSI generation module to generate a linked CSI including an inherited RI from the first Reference CSI.
Abstract:
A User Equipment and an eNodeB system are configured for performing interference mitigation in the UE. Input circuitry in the wireless communication device receives an OFDM downlink channel signal associated with a serving cell and receives downlink control information for an interfering cell. The downlink control information is used by the UE to perform channel estimation for the interfering cell. An interference mitigation module is provided for calculating an interference-mitigated version of the received channel signal using estimated channel transfer functions for both the serving cell and the interfering cell, power control parameters and using set of modulation constellation points corresponding to the OFDM downlink channel. Other embodiments may be described and claimed.
