Abstract: A wireless network may include a base station and user equipment (UE). The UE may transmit uplink (UL) signals to the base station using a dynamically adjustable maximum UL duty cycle. When the UE identifies that a user is in proximity to the UE, the UE may transmit an indicator to the base station. The indicator may identify that a radio-frequency exposure (RFE) event has occurred and/or a suggested maximum UL duty cycle that would allow the UE to satisfy limits on RFE. The base station may limit a UL grant to the UE so that the UE performs subsequent communications using the suggested maximum UL duty cycle or a different maximum UL duty cycle. Coordinating adjustment of UL duty cycle in this way may allow the UE to meet limits on RFE without requiring the UE to perform maximum transmit power level reductions.

Abstract: This disclosure relates to techniques for configuring physical uplink shared 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 uplink data transmission configuration information to the wireless device. The uplink data transmission configuration information may configure an uplink data transmission to multiple transmission-reception-points. The cellular base station may receive at least a portion of the uplink data transmission.

Abstract: Apparatuses, systems, and methods for utilization of an iner-UE coordination message. A UE may receive, from a first UE, an inter-UE coordination message. The inter-UE coordination message may include an indication of a set of resources and an indication of whether the set of resources are preferred resources or non-preferred resources. The UE may be configured to select resources for sidelink communications based on the set of resources indicated in the inter-UE coordination message. The UE may perform differing selection processes based on the set of resources indicated in the inter-UE coordination message. The UE may perform a first process and/or set of processes when the set of resources are indicated as non-preferred and a second process and/or set of processes when the set of resources are indicated as preferred.

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.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for triggering a change in beam configuration based on UL beam conditions. The UE may detect an unsafe UL beam condition for an UL beam based, at least in part, on an MPE level being exceeded by the UL beam. In response to the detection, remedial actions that to alleviate the unsafe UL beam condition may be performed. The remedial actions may prioritize UL beam quality over DL beam quality and may include reducing a transmit power of the UL beam based on an MPR, triggering an intra-panel antenna switch to a candidate UL beam that satisfies one or more conditions for intra-panel beam switching, triggering an inter-panel antenna switch to a candidate UL beam that satisfies one or more conditions for intra-panel beam switching, and/or signaling a beam failure to a network serving the UE.

Abstract: Disclosed are techniques for reducing likelihood of Random Access Channel (RACH) transmission blockages and thereby facilitate an initial access procedure for new radio (NR) unlicensed spectrum (NR-U) operation in a fifth generation (5G) wireless communication system including an NR node. In some embodiments, a parameter generated by a gNB and received by a UE indicates that, from among a set of consecutive RACH Occasions (ROs), a gap is available for performing a listen-before-talk (LBT) procedure before commencing a RACH transmission.

Abstract: Methods, systems, and devices for wireless communications are described. To monitor a PDCCH for CA, a UE may receive PDCCH candidates in a plurality of configured component carriers (CCs). In response to a determination that a maximum number of virtual CCs that the UE is capable of monitoring for PDCCH is smaller than a number of the plurality of configured CCs, the UE groups the plurality of configured CCs into CC groups based at least in part on SCS numerologies and PDCCH monitoring configurations corresponding to span patterns within a slot of a DL subframe. The UE determines a maximum number of blind decoding operations and non-overlapped CCEs for each of the CC groups. The UE then monitors at least a first portion of the PDCCH candidates based on the maximum number of blind decoding operations and non-overlapped CCEs for each of the CC groups.

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.
