Abstract: Apparatuses, systems, and methods for channel access scheme enhancements for systems operating in unlicensed higher frequency bands. A wireless device may perform channel access detection (CAD) measurements on a channel at a first periodicity, determine a CAD metric based on the CAD measurements at a second periodicity, and select, for the channel, a first channel access scheme from a plurality of channel access schemes based on comparison of the CAD metric to a threshold. The first channel access scheme may include a first set of channel access procedures that may define physical channels and signals to utilize respective channel procedures. In instances when the CAD metric is below the threshold, the first channel access scheme may include accessing a channel using a first listen before talk (LBT) procedure that is less restrictive than a second LTB procedure used when the CAD metric is above the threshold.

Abstract: Methods and devices for a base station acting as a primary cell to perform dual spectrum sharing (DSS) with a first user equipment device (UE) over a 5G NR connection and a second UE over an LTE connection. The first UE establishes the 5G NR connection with the primary cell and one or more secondary cells. One of the secondary cells is configured in the 5G NR connection to provide downlink control information to the UE for the primary cell, to avoid collisions by the primary cell with LTE control transmissions.

Abstract: Apparatuses, systems, and methods for SRS antenna switching. A UE may transmit, to a base station, a capability message indicating an antenna configuration associated with SRS antenna switching e.g., via as RRC signaling. The capability message may indicate at least one of (and/or one or more of) a one transmit point (1T) and six receive point (6R) SRS resource set configuration, a 1T8R SRS resource set configuration, a 2T6R SRS resource set configuration, a 2T8R SRS resource set configuration, and/or a 4T8R SRS resource set configuration. The UE may receive, from the base station, a configuration message, e.g., via RRC signaling. The configuration message may indicate an SRS antenna switching configuration based, at least in part, on the capability message. The UE may transmit, to the base station, one or more SRSs, e.g., according to the SRS antenna switching configuration.

Abstract: This disclosure relates to techniques for providing control signaling for robust uplink data transmissions in a wireless communication system. A wireless device may be configured to perform an uplink transmission, including performing multiple repetitions of the uplink transmission. The wireless may select a beam for each repetition, and it may be the case that different repetitions are transmitted using different beams.

Abstract: This disclosure relates to techniques for a wireless device to initiate channel occupancy in unlicensed spectrum in a wireless communication system. The wireless device may establish a wireless link with a cellular base station. The wireless device may determine to perform an uplink transmission to the cellular base station on an unlicensed frequency channel. The wireless device may determine whether the cellular base station has channel occupancy of the unlicensed frequency channel. The wireless device may determine whether to initiate channel occupancy of the unlicensed frequency channel. The decision whether to initiate channel occupancy may be based at least in part on whether the cellular base station has channel occupancy of the unlicensed frequency channel.

Abstract: A base station is configured to receive channel state information (CSI) from a user equipment (UE). The base station transmits configuration information including one or more interference measurement resources (IMRs) allocated for measurement by the UE, receives a reference CSI report from the UE, receives a new CSI report including interference and noise power fluctuation feedback from the UE and selects a modulation and coding scheme (MCS) for the UE based on at least the interference and noise power fluctuation feedback and the reference CSI report.

Abstract: This disclosure relates to techniques for improving capability signaling and performing search space set switching, particularly with large sub-carrier spacings, as in high frequency ranges. In various scenarios, a user equipment (UE) device may signal its capability to perform multi-slot PDCCH monitoring and/or single-slot PDCCH monitoring, e.g., at various sub-carrier spacings, for various PDCCH/DCI types, etc. Various technical difficulties in this area are addressed, including increasing flexibility and versatility in capability signaling, overbooking, signaling and timing of search space set switching, and beam sweeping transmission of DCI Format 2_0, among others.
