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:
Hybrid beam-forming (BF) radio communications are carried out between a base station (BS) and a set of user equipment (UEs) within a service area. The hybrid BF operations include a sector-sweep operation to identify analog beam-forming (BF) parameters for individual ones of the set UEs within the service area. A first subset of UEs is selected from among the set of UEs, the first subset of UEs being subject to channel quality assessment (CQA). The UEs of the first subset are configured to transmit CQA signaling, the CQA signaling being based on the analog BF parameters. Digital BF parameters are computed for the UEs of the first subset based on the CQA signaling.
Abstract:
The present disclosure provides blockage detection for AP services. Detecting blockages can include storing a plurality of access point (AP) identifications (IDs). Detecting blockages can also include generating an ordered BMS of AP IDs that correspond to a plurality of APs, encoding a PDCCH to provide to a UE via a mmWave frequency, wherein the PDCCH incorporates a B-Poll channel, determining that an ACK for the PDCCH is not received from the UE, and detecting a blockage of an AP, of the ordered BMS of AP IDs, servicing the UE based on the determination that the ACK for the PDCCH is not received from the UE. Detecting blockages can also include selecting a next AP ID from the BMS and generating an offload message to instruct a next AP with the next AP ID to provide an AC to the UE.
Abstract:
An apparatus for use in an eNodeB of a cellular network, that facilitates dynamic random access channel (RACH) design, comprising a processing circuit that, upon execution of instructions from a memory circuit, is configured to determine channel parameters for a RACH phase of a random access channel that exists between the eNodeB and one or more user equipments (UEs) in a coverage area of the eNodeB, based on a load information of the eNodeB. In some embodiments, the channel parameters comprise information on one or more sequential random access windows (RAWs) within the RACH phase. Further, the processing circuit is configured to generate a system information message comprising the channel parameters for downlink transmission to the one or more UEs.
Abstract:
The present disclosure includes systems and methods for supporting polar codewords with variable polar codeword lengths. Variable codeword length codewords are communicated using an n-bit encoder/n-bit decoder having n inputs and n corresponding outputs. Each input and each corresponding output is associated with a bit index. A set of bit indices to be shortened are selected. The encoder encodes n input bits to obtain n output bits. Each output bit that is associated with a bit index from the set of bit indices to be shortened is ignored. A codeword is generated from all of the remaining output bits.
Abstract:
Network devices and systems in 5G advance long term evolution (LTE) and new radio (NR) infrastructures utilize beam management operations to ensure communications for channel state information (CSI) reporting by a user equipment (UE). CSI report configuration reporting settings are processed based on a codebook subset restriction to indicate pre-coding matrix indicators (PMIs) that are restricted and non-restricted for PMI reporting associated with a rank indicator (RI). Based on the codebook subset restriction, an advanced CSI codebook or a new radio (NR) codebook is generated to be transmitted on non-restricted beams of the codebook subset restriction.
Abstract:
Techniques discussed herein can facilitate mapping of codewords to MIMO (Multiple Input Multiple Output) layers for 5G (Fifth Generation) NR (New Radio) systems. Some example embodiments discussed herein can map codeword(s) to MIMO layers based on predefined mappings discussed herein. The same or other example embodiments can generate or process configuration signaling that can comprise an indication of an indicated maximum number of MIMO layers for a CC (Component Carrier).
Abstract:
Technology for a user equipment (UE) configured to communicate using polar coding and rate matching is disclosed. The UE can select K data bits and can determine a coding rate r. The UE can determine a number of parity bits, NTx, for transmission, with the number of NTx parity bits based on the K data bits and the coding rate r. The UE can encode the K data bits into N coded bits, with the K data bits based on a polar code of a length N. The UE can select, for transmission to the next generation node B (gNB), the Ntx parity bits from the N coded bits using a circular buffer bit selection. The NTx parity bits can be based on a permutation of length N using a permutation pattern of length N that is used: to puncture the polar code, or in a sub-block permutation.
Abstract:
Embodiments of a station (STA) and method for communication in accordance with phase noise compensation are generally described herein. The STA may determine, based at least partly on one or more operational parameters, whether to perform phase noise compensation of data symbols of a received protocol data unit (PDU). For instance, the STA may compare the operational parameters with one or more thresholds. The STA may further determine a method of phase noise compensation based at least partly on one or more operational parameters. As an example, the STA may determine a type of interpolation to be used for an interpolation of phase noise estimates of pilot symbols to determine phase noise estimates of data symbols. Example operational parameters may include a signal quality metric, a carrier frequency offset (CFO) measurement and/or modulation and coding scheme (MCS).
