Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to perform downlink control information (DCI) mode signaling and control resource set (CORESET) selection. A DCI mode may be signaled based on a predefined rule, media access control (MAC) control element (CE), and/or group based beam reporting. One or more CORESETs may be selected based on configuration of an active bandwidth part (BWP), CORESET identifier, higher layer index, periodicity, type of search space, and/or MAC CE.

Abstract: A method and apparatus for a wireless device of reduced capabilities to access a wireless communication network targeted to operate with wireless device having higher capabilities is disclosed. The device may receive from a base station of the wireless communication network an indication of whether the type of devices that includes the wireless device of reduced capabilities is allowed to access the wireless communication network. The device may transmit to the base station signaling associated with connecting to the base station if the base station indicates that the type of devices with reduced capabilities is allowed to access the wireless communication network. The signaling allows the device to connect to the base station. The device may transmit capability information of the device to the base station. The device may configure its features based on the capability information to communicate with the base station.

Abstract: Apparatuses, systems, and methods for selecting channel access mechanisms in wireless communications, and particularly in 3GPP NR-U. For example, an appropriate listen-before talk (LBT) channel access category (Cat) may be defined for certain messages, such as certain DL and/or UL control messages and certain RACH messages. For other messages, an appropriate Cat may be signaled by the base station, e.g., in a DCI message or SIB. Mechanisms are provided for the base station to signal to the UE certain channel access profile parameters, such as an appropriate LBT Cat, CAPC, and/or CP extension. Mechanisms are also provided for adjustment of contention window duration.

Abstract: A user equipment (UE) operates in a network. The UE receives, from the network, a paging area comprising a plurality of cells of the network. When the UE is in one of a radio resource control (RRC) inactive state or RRC idle state with respect to the network, the UE transmits a message to a first cell of the paging area based on the UE moving into a first coverage area of the first cell from a second coverage area of a second cell of the paging area. The UE then monitors the first cell for a page from the network.

Abstract: This disclosure relates to orthogonal frequency division multiple access (OFDMA) communication in wireless local area networks (WLANs). According to some embodiments, a downlink OFDMA frame may be transmitted. An uplink OFDMA frame including acknowledgements associated with the downlink OFDMA frame may be received. The uplink OFDMA frame may be processed, in some instances including determining which devices receiving the downlink OFDMA frame transmitted an acknowledgement associated with the downlink OFDMA frame in the uplink OFDMA frame.

Abstract: A method for operating user equipment (UE) includes generating, by the UE, a transmit precoding matrix indicator (TPMI) list including one or more TPMIs selected from a set of available TPMIs stored at a base station (BS). Data indicative of the TPMI list is transmitted to the BS. An index of the TPMI list is transmitted to the BS. Downlink control information (DCI) is received from the BS including an indication of at least one TPMI from the TPMI list based on the index. Uplink data is transmitted to the BS on a physical uplink shared channel (PUSCH) using the at least one TPMI.

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: Apparatuses, systems, and methods for a user equipment device (UE) to determine a default beam for a dedicated PUCCH/SRS in a CC. The UE may determine a pathloss RS has been configured in the CC, e.g., responsive to the UE determining that spatial relationship information for a default transmission beam has not been configured and determine the default beam for transmissions based, at least in part, on the (configured) pathloss RS. Additionally, responsive to determining that the pathloss RS has not been configured in the CC, the UE may determine that no CORESETs/TCI states for a PDSCH in the CC have been configured and determine the default beam for transmissions based, at least in part, on a default transmission beam in another CC, a CC index, a PRACH procedure; a PUSCH transmission; an SRS transmission, and/or a PUCCH transmission.

Abstract: TDD configuration may be dynamically and/or semi-statically signaled to user equipment devices by a base station. Semi-static TDD configuration may include: an initial portion for downlink transmission; a flexible portion; and a terminal portion for uplink transmission. TDD structure of the flexible portion may be determined later by transmission of dynamic physical layer configuration information such as downlink control information (DCI) and/or slot format indicator (SFI). (The SFI may be included in a group common PDCCH of a slot.) The downlink portion and/or the uplink portion may include subsets whose nominal transmit direction is subject to override by transmission of dynamic physical layer configuration information.
