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: A generation-Node B (gNB) configured for unlicensed spectrum operation above 52.6 GHz in a fifth-generation new-radio (NR) system (5GS) may encode a parameter (e.g., ssb-PositionsInBurst) for transmission to a UE (e.g., in the SIB1 or UE specific RRC signalling). The parameter may indicate candidate positions of synchronization signal blocks (SSBs) within a discovery reference signal (DRS) measurement timing configuration (DMTC) transmission window within slots of a system frame (SFN). During the DMTC window, the gNB may perform a LBT procedure on an unlicensed carrier of the unlicensed spectrum to determine if the unlicensed carrier is available. When the LBT is successful (i.e., the unlicensed carrier is available), the gNB may encode a discovery reference signal (DRS) for transmission on the unlicensed carrier. The DRS may include one or more of the SSBs transmitted during the candidate positions that fall within the DRS.

Abstract: Disclosed embodiments are related to beam management in cellular communication networks, and in particular, provide a new transmission (Tx) beamforming indication based on the flexible Tx beam-forming assignment on the corresponding reference signal configured in a transmission configuration indicator (TCI) state for downlink (DL) or spatial relation information in the uplink (UL).

Similarly, spatial relation information configuration used to indicate Tx beam-forming in the UL, may be also updated based on the reference signal measurements in DL or by suing Downlink Control Information (DCI) based beam indication in a scheduling request indicator (SRI). Other embodiments may be described and/or claimed.

The approach further includes constructing a precoding matrix based on a linear combination of a plurality of mutually orthogonal digital Fourier transformation (DFT) spatial beams, and determining a number of bits for the PMI of the precoding matrix. The approach also includes determining a space frequency matrix based, at least in part, on the number of bits for the PMI and the precoding matrix, and compressing the space frequency matrix. Finally, the approach includes determining a compressed PMI based, at least in part, on the space frequency matrix.

Abstract: An apparatus for a UE includes processing circuitry coupled to memory. To configure the UE for shared spectrum channel access in a 5G-NR system, the processing circuitry is to decode a synchronization signal (SS)/physical broadcast channel (PBCH) block (SSB) to obtain a master information block (MIB). System information block 1 (SIB1) configuration information is determined using the MIB. The SIB1 configuration information is used to configure a Type 0 PDCCH common search space (CSS) set (CORESET). The processing circuitry is to monitor for a PDCCH in the Type 0 PDCCH CSS set over slots that include Type 0 PDCCH monitoring occasions. At least one of the slots includes the SSB and the CORESET multiplexed according to multiplexing pattern 1. The PDCCH is detected in at least one of the Type 0 PDCCH monitoring occasions. A SIB1 is decoded using downlink control information (DCI) received via the detected PDCCH.

Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for a single downlink control information (DCI) signal that supports multi-transmission reception point (TRP) transmissions from different TRPs (e.g., different 5G Node Bs or different antenna panels.) A user equipment (UE) receives a single DCI signal that includes a first transmission configuration indicator (TCI) state of a first TRP, a second TCI state of a second TRP, and a demodulation reference signal (DMRS) port indication value. The UE uses the DMRS port indication value to determine a first DMRS port and a first code division multiplexing (CDM) group of the first TCI state and a second DMRS port and a second CDM group of the second TCI state. The UE receives a multi-Physical Downlink Shared Channel (PDSCH) signal that includes multi-TRP transmissions, and uses the above determinations to decode data from the first and/or the second TCI states.

Abstract: Various embodiments herein provide techniques for user equipment (UE) behavior and delay requirements in case of spatial relation information change for an uplink signal, such as a sounding reference signal (SRS), a physical uplink control channel (PUCCH), and/or a physical uplink shared channel (PUSCH).

The delay time period includes a decoding time period and a UE processing and preparation time period. The UE transmits an uplink signal using the indicated spatial relation information after expiration of the delay time period.
