Abstract: A device may wirelessly communicate with a number of different cells used in a carrier aggregation. The device may monitor physical downlink control channels (PDCCHs) on the different cells, dynamically switching between a dormant monitoring state (DS) and an active monitoring state (AS). In the DS, the UE may not monitor any PDCCH candidates on the active secondary SCells corresponding to the DS, or it may monitor PDCCH candidates in the search space (SS) set with the largest monitoring periodicity among the multiple SS sets on the active bandwidth part (BWP). In the AS, the UE may monitor a set of PDCCH candidates in physical resources configured by higher layers on the BWPs. Switching from one monitoring state to another may be facilitated through the use of a new downlink control information (DCI) format without data scheduling, a modified existing DCI format with data scheduling, and/or use of a DS timer.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods to implement mechanisms for a UE to request a beam quality measurement procedure. A user equipment device may be configured to perform a method including performing transmitting a request to perform a beam quality measurement procedure for downlink receptions (e.g., a P3 procedure) to a base station/network entity, receiving instructions to perform the beam quality measurement procedure from the base station, and transmitting results of the beam quality measurement procedure to the base station. In some embodiments, transmission of the request may be response to at least one trigger condition and/or detection of a condition at the UE. The request may include an indication of a preferred timing offset. The instructions to perform the beam quality measurement procedure may include a schedule for the beam quality measurement.

Abstract: This disclosure relates to techniques for a wireless device to indicate a preferred bandwidth part and duty cycle in a cellular communication system. A wireless device and a cellular base station may establish a radio resource control connection. The wireless device may transmit an indication of a preferred bandwidth part, or a preferred communication duty cycle, or both, to the cellular base station. The cellular base station may select a bandwidth part, or communication duty cycle, or both, based at least in part on the indication provided by the wireless device, and may transmit an indication of the selected bandwidth part, communication duty cycle, or both, to the wireless device. The cellular base station and the wireless device may perform cellular communication using the selected bandwidth part, communication duty cycle, or both.

Abstract: In an example method, a user equipment (UE) device determines one or more component carriers available to the UE device for at least one of transmitting or receiving data over a wireless network. The UE device transmits, to the wireless network, for each component carrier, an indication whether the component carrier supports at least one of transmitting or receiving data according to a multi-transmission and receiving points (multi-TRP) communication protocol.

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: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for Fifth Generation New Radio (5G NR) frequency range two (FR2) based communications beam management. The UE may configure, via communications with a base station, serving the UE, a group ID for PUCCH resources within a group of PUCCHs, e.g., for FR2 based communications. The UE may receive, from the base station, an update to one or more PUCCH resources within the group of PUCCHs via a medium access control (MAC) control element (CE) that may include one of a resource ID indicating an update to a PUCCH resource or the group ID to update the group of PUCCH resources. The UE may update, based on the MAC-CE, the one or more PUCCH resources within the group of PUCCHs.

Abstract: A wireless device may comprise antennas and a processor configured to cause the wireless device to determine preferred antenna ports for at least one primary component carriers (PCCs) and at least one secondary component carriers (SCCs) based on performed downlink measurements of antenna ports. The wireless device may further determine support capabilities of the wireless device and perform computations using additional measurements of the antenna ports. Based on the computations, the wireless device may assign the preferred antenna ports to the PCCs and SCCs and perform uplink transmission using the assigned antenna ports.

Abstract: Apparatuses, systems, and methods for providing maximum transmit power control when utilizing multiple radio access technologies. For example, a wireless communication device comprising two cellular radios may intend to transmit on the first radio, while concurrently transmitting on the second radio. To ensure compliance with a maximum transmit power limitation, the device may determine an allowed transmit power level of the first radio, representing a difference between the maximum transmit power limitation and the current transmit power level being transmitted by the second radio. The device may also determine a threshold power level for a communication by the first radio. If the allowed transmit power level meets the threshold power level, then the device may transmit the first communication having a power level between the threshold power level and the allowed transmit power level. Otherwise, the device may forego transmission of the first communication.
