Abstract: Disclosed are methods and apparatuses for improving reliability and reducing power consumption for FR2 RRM. In one aspect, a UE is capable of maintaining connectivity of a first RAT and connectivity of a second RAT. The UE is configured to send a RAT request to the cellular network, the RAT request indicating at least one preferred RAT that is selected from the first RAT and the second RAT, and use the at least one preferred RAT to carry data transmission between the UE and the cellular network.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for determining resources for scheduling side-link communications. The resources may be semi-persistent and/or dynamic resources. A user equipment device (UE) may determine a resource map for use in scheduling semi-persistent resources for side-link communications with at least one wireless node. The UE may transmit a resource map request message indicating preferred resource blocks, where each resource block may be defined by a time and a frequency. The UE may receive a confirmation message that may include a report regarding a set of resource blocks. The set of resource blocks may be from the preferred resource blocks included in the resource map request message. The UE may determine, based, at least in part, on the confirmation message, resource blocks to be used for the side-link communications and initiate the side-link communications using the determined resource blocks.

Abstract: Apparatuses, systems, and methods to indicate power transmission capability for a wireless device. A wireless device may connect to a base station (BS). The wireless device may transmit information regarding transmit power capability to the BS. The wireless device may indicate support for full power transmit capability for a subset of TPMIs for which it provides full power transmit capability, e.g., in a bitmap. This subset of TPMIs may be less than all of the available TPMIs (i.e., it may be a strict subset of the available TPMIs). Full power transmission capability of these indicated TPMIs may be provided via antenna switching and/or antenna virtualization. The wireless device may perform uplink transmission to the BS according to the transmit power capability indicated in the information. For example, the UE may transmit data using the antenna virtualization related to the subset of the TPMIs.

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 user equipment device (UE) to perform multiple TTI PUSCH transmissions in a wireless communication system as well as code block groups (CBGs) based retransmissions operations. A UE may perform radio resource control (RRC) signaling with a network entity to configure a data structure that may include one or more sets of physical uplink shared channel (PUSCH) transmission configurations, where each set of PUSCH transmission configurations span multiple TTIs. The wireless device may be configured to receive, from the network entity, a downlink control information (DCI) message that may include a time domain resource assignment field (TDRA) that may indicate a set of PUSCH transmission configurations included in the data structure. The wireless device may perform PUSCH transmissions spanning multiple TTIs according to the indicated set of PUSCH transmission configurations over an unlicensed band.

Abstract: A method performed by a user equipment (UE) configured with a plurality of antenna panels. Each antenna panel is configured to beamform over a millimeter wave (mmWave) frequency band. The method includes identifying a predetermined condition corresponding to a first antenna panel of the plurality of antenna panels, selecting a second antenna panel of the plurality of antenna panels based on identifying the predetermined condition corresponding to the first antenna panel and transmitting a beam via the second antenna panel based on the selection.

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.
