Abstract: Various systems and methods disclosed herein describe improvements for beam management that leverage virtualization across a vertical polarization (V-Pol) and horizontal polarization (H-Pol). One or more of a user equipment (UE) and a base station may include an antenna array comprising both V-Pol and H-Pol antenna elements. A UE may message a base station to configure uplink (UL) multiple input multiple output (MIMO) operations across one or more of the V-Pol and the H-Pol. The message may include a number of MIMO layers to be concurrently used for communicating data to the base station, where each MIMO layer is transmitted using one of a V-Pol and an H-Pol; a number of sounding reference signals (SRS) to be transmitted by the UE, each SRS to be transmitted using one of the V-Pol and the H-Pol; and a supported maximum number of antenna ports per each SRS.

Abstract: Provided is a method for a user equipment (UE). The UE may performs at least one of: monitoring physical downlink control channels (PDCCHs) in a Type0-PDCCH common search space (CSS) set over one or two consecutive slots, starting from a slot index n_0, with a 480 kHz or 960 kHz subcarrier spacing (SCS); transmitting, to a base station (BS), a report of a UE capability related to search space configurations for multi-slot PDCCH monitoring; or performing a monitoring occasion (MO) shifting operation for a first group of search space (SS) sets in response to a determination that a second group of SS sets is updated.

Abstract: A downlink control information (DCI), such as a blanking DCI (bDCI) message may be transmitted by a base station (e.g., eNB) and received by a mobile device (e.g., UE). The bDCI may indicate that the eNB will not transmit a subsequent DCI to the UE for a duration of time. The UE may be in continuous reception mode or connected discontinuous reception (C-DRX) mode. The UE may therefore determine to enter a sleep state or take other action. The bDCI may specify an explicit blanking duration, or an index indicating a blanking duration from a lookup table, and/or the blanking duration (and/or a blanking duration offset value) may be determined in advance, e.g., semi-statically. When the UE is in C-DRX mode, the UE may be configured such that either the sleep/wake period of the C-DRX mode or the blanking period of the bDCI may take precedence over the other.

Abstract: Apparatuses, systems, and methods for beam indication latency reduction via symbol level beam sweeping capability reporting. A wireless device may transmit, to a base station, a report associated with symbol level beam sweeping. The wire wireless device may receive, from the base station, a symbol level beam sweeping configuration. The symbol level beam sweeping configuration may be based, at least in part, on the report. The wireless device may perform synchronization signal block (SSB) measurements according to the report and the symbol level beam sweeping configuration.

Abstract: This disclosure relates to techniques for configuring and providing physical downlink control channel transmissions with improved reliability in a wireless communication system. A cellular base station may establish a wireless link with a wireless device. The cellular base station may provide downlink control channel configuration information to the wireless device. The downlink control channel configuration information may configure control resources associated with multiple transmission reception points in a search space for the wireless device. The cellular base station may provide downlink control information to the wireless device using control resources included in the search space.

Abstract: Improved configured grants (CGs) may include the designation of a footprint corresponding to uplink transmission of a UE, with the footprint at least partially defined by the occupied transmission time, occupied transmission frequency, and transmission power. The footprint may be adjustable and/or selectable by the UE according to the current traffic needs of the UE and within limits set for the footprint via prior signaling from the base station to the UE. The UE may indicate the actual footprint parameters/values for the UE's uplink data transmissions by transmitting CG uplink control information (CG-UCI) inclusive of the actual footprint values to the base station. The UE may transmit the CG-UCI over resources configured according to additional parameter values received via the prior signaling from the base station. The UE may further transmit uplink data on resources configured according to the actual footprint values.

Abstract: Reporting capabilities regarding Cross Carrier Scheduling (CCS) with different Sub-Carrier Spacing (SCS) may include generating a message to send to a base station. The message may comprise an indication of a user equipment's (UE's) capability for CCS with different SCS. Based on the UE's capability for CCS with different SCS, a number of unicast downlink control information (DCI) per physical downlink control channel (PDCCH) monitoring occasion per span may be processed to determine scheduled resources for downlink (DL) and uplink (UL) signaling or channels. The DL and UL signaling or channels may be processed using the scheduled resources.
