Technology for selecting physical resource blocks (PRB) for cell-specific reference signal (CRS) transmission for a new carrier type (NCT) is disclosed. In an example, device operable in an evolved Node B (eNB) to select physical resource blocks (PRB) for cell-specific reference signal (CRS) transmission for a new carrier type (NCT) can include computer circuitry configured to: Determine a frequency bandwidth for the NCT; and select a CRS pattern of PRBs for a transmission of the CRS in the frequency bandwidth, wherein the frequency bandwidth includes PRBs with CRS and PRBs without CRS.
Abstract:
Systems, apparatuses, methods, and computer-readable media are provided for enhanced demodulation reference signal (DMRS) for uplink transmissions with up to eight layers (e.g., an uplink single user (SU)-multiple input, multiple output (MIMO) transmission). Additionally, embodiments relate to antenna port indication for DMRS transmission. Other embodiments may be described and claimed.
Abstract:
Various embodiments herein provide techniques for minimum mean-square error interference rejection combining (MMSE-IRC) processing of a received signal, distributed between a baseband unit (BBU) and a remote radio unit (RRU). The RRU may perform uplink receive beamforming (e.g., using maximum ratio combining (MRC)) based on multiple channel measurements (e.g., a set of multiple sounding reference signal (SRS) channel measurements) obtained on respective measurement signals transmitted by a user equipment (UE). The RRU may send the processed signal to the BBU for further processing. The BBU may perform MMSE-IRC based on the processed signal received from the RRU, e.g., using demodulation reference signals (DM-RSs). Other embodiments may be described and claimed.
Abstract:
Various embodiments herein are directed to set physical downlink shared channel (PDSCH) default beam behavior for single transmission-reception point (TRP), single downlink control information (DCI) multi-TRP and multi-DCI multi-TRP operation, as well as physical downlink control channel (PDCCH) prioritization based on quasi-colocation (QCL) Type-D for multi-panel reception and single panel reception.
Abstract:
Various embodiments herein provide techniques for synchronization signal block (SSB) configuration for wireless cellular networks. The SSB may be for carrier frequencies above 52.6 gigahertz (GHz). Other embodiments may be described and claimed.
Abstract:
A user equipment (UE) configured for multi-slot physical downlink control channel (PDCCH) monitoring may decode higher-layer signalling comprising configuration information received from a gNodeB (gNB) that configure the UE with search space (SS) sets for multi-slot PDCCH monitoring. At least some slots of the SS sets may be indicated to have a PDCCH monitoring occasion (MO). A SS set may be configured in a number (Y) of consecutive non-overlapping slots (MO slots) within slot groups of a number (X) of consecutive non-overlapping slots. The number (X) of consecutive slots of the slot group may be at least twice the number (Y) of consecutive MO slots within each SS set. The number (X) of consecutive slots of the slot group and the number (Y) of consecutive MO slots within each SS set that comprise the PDCCH MO may also be based on a subcarrier spacing (SCS).
Abstract:
An apparatus and system to compensate for phase noise in a 5G or 6G DFT-S-OFDM signal are described. An access port (AP)-specific orthogonal cover code (OCC) is applied to phase tracking reference signal (PTRS) symbols in each of a plurality of PTRS groups. The PTRS group are inserted between data symbols to form a data vector prior to perform transform precoding on the data vector and transmission to a UE. The UE extracts the PTRS symbols from different PTRS APs using the OCC specific to each AP. After extraction, the phase noise for each PTRS group is estimated and used to compensate the data symbols associated with the PTRS group.
