Abstract: User equipment (UE)-specific information may be transmitted within a control resource set configured to carry resources common to UEs within a system. The UE-specific information may be associated with a search space having an aggregation level different from aggregation levels used with the common control resources and may occupy different modulation symbols within the common control resource set (e.g., to support flexible scheduling for multiple UEs). A base station and UE may operate in a system using one or more control resource sets within a system bandwidth. The UE may detect common control resources by monitoring decoding candidates in the control resource set according to a first set of aggregation levels. The UE may detect UE-specific control resources by monitoring decoding candidates in the control resource set according to other aggregation levels. The UE and base station may communicate based on control information obtained from the monitoring.

Abstract: Various aspects of the disclosure relate to controlling reporting operations based on the timing of certain reporting events. In some aspects, the manner in which an apparatus performs reporting operations may depend on how far apart in time two reporting events occur. As one example, if the timing of an event-triggered report closely follows the timing of a request-triggered report, the apparatus may skip or otherwise alter the event-triggered reporting.

Abstract: Disclosed are techniques for transmit/receive (TX/RX) beam association in millimeter wave (mmW) vehicle-to-everything (V2X) communications. In conventional wireless systems, a node (e.g., gNB) that manages wireless resources is typically stationary. This means that transmissions from the network node over the same TX beam using the same antenna array orientation can be assumed to be quasi-collocated (QCLed) and communications may be established using fixed-to-mobile beam management approach. However, if the transmitting node is mobile, a quasi-collocation (QCL) assumption may not be valid. To address issues due to mobility of the nodes that manage wireless resources, a mobile-to-mobile beam management approach is proposed.

Abstract: Certain aspects of the present disclosure provide techniques for sounding reference signal (SRS) resource configuration enhancements. A method generally receiving pre-configuration information for one or more reference signal transmissions, performing, at a first time during an ON duration of a discontinuous reception (DRX) cycle, measurements on one or more reference signals based, at least in part, on the pre-configuration information, determining if, at a second time during the ON duration after the first time, a trigger frame associated with the one or more reference signal transmissions has been received, and transmitting a measurement report corresponding to the measurements if a trigger frame has been received.

Abstract: Embodiments provided herein allow for identification of one or more regions of interest in a radar return signal that would be suitable for selected application of super-resolution processing. One or more super-resolution processing techniques can be applied to the identified regions of interest. The selective application of super-resolution processing techniques can reduce processing requirements and overall system delay. The output data of the super-resolution processing can be provided to a mobile computer system. The output data of the super-resolution processing can also be used to reconfigure the radar radio frequency front end to beam form the radar signal in region of the detected objects. The mobile computer system can use the output data for implementation of deep learning techniques. The deep learning techniques enable the vehicle to identify and classify detected objects for use in automated driving processes. The super-resolution processing techniques can be implemented in analog and/or digital circuitry.

Abstract: Methods, systems, and devices for wireless communication are described. Wireless communications systems may support beamformed transmissions between devices (e.g., to improve coverage range). The beamformed transmissions may depend on discovery and maintenance of receive and transmit beams over which a given device may communicate with another device. Various receive and transmit beams for a given device may be compared using reference signals. As the number of devices attempting to access a cell increases, the number of reference signals to be transmitted may scale proportionally. Large numbers of reference signals may flood time-frequency resources of the system and/or require excessive processing at a mobile device. Scrambling sequences for reference signals may be employed to improve efficiency of resource usage. In aspects, the scrambling sequences may be implicitly determined (e.g., based on resources over which the access request was transmitted). Such an implicit association may reduce the need for additional signaling.

Abstract: In multi-beam communication, the UE may assist in the scheduling of beams utilized during the multi-beam communication by improving the manner in which the quality of the beam is reported to the network. The apparatus may measure a signal received from a base station on at least one beam. The apparatus may detect a triggering event for providing CSI for the at least one beam. The apparatus may transmit an uplink transmission comprising a CSI report in response to detecting the triggering event. The apparatus may receive an uplink request from a UE for providing CSI for at least one beam. The apparatus may transmit an indication scheduling a CSI report in response to the uplink request. The apparatus may receive an uplink transmission from the UE comprising the CSI report for the at least one beam.

In some aspects, a user equipment (UE) may receive, from a first transmit receive point (TRP), a downlink control information (DCI) communication, the UE being included in a multi-TRP configuration with the first TRP and a second TRP. The UE may determine information unique to the first TRP. The information unique to the first TRP may be at least one of associated with the DCI communication or included in the DCI communication. The UE may generate a downlink scrambling sequence initialization code, associated with the first TRP, based at least in part on the information unique to the first TRP. The UE may generate a downlink scrambling sequence, associated with the first TRP, based at least in part on the downlink scrambling sequence initialization code associated with the first TRP. Numerous other aspects are provided.
