Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for enhancing uplink (UL) repetitions for an associated transport block. A user equipment device (UE) may be configured to transmit an indication of cancellation of remaining UL repetitions to a network, e.g., to a network entity, such as a base station, e.g., based, at least in part, on monitored channel conditions. Additionally, a network, e.g., a network entity such as a base station, may be configured to transmit an indication of cancellation of remaining UL repetitions to a UE, e.g., based on successful reception of the associated transport block.

Abstract: Systems, methods, and circuitries are provided for direct transmission of uplink data by an INACTIVE UE using a contention free random access (CFRA) process. In one example, a method, includes, receiving uplink data from transmitted by a user equipment (UE) device while the UE is in a radio resource control (RRC) INACTIVE state, wherein the UE uses a contention-free random access (CFRA) process to transmit the uplink data using a dedicated physical random access channel (PRACH) resource or a dedicated preamble resource (dedicated PRACH/preamble resource) assigned to the UE by a network.

Abstract: Techniques discussed herein can facilitate inactive state transmissions for a User Equipment (UE) via a 4-step or 2-step inactive state RACH process. One example aspect is a UE device, comprising: communication circuitry; and a processor configured to perform operations comprising: in response to a determination to perform a Radio Resource Control (RRC) inactive data transmission: transmitting, via the communication circuitry, a message 1 (Msg1) or a message A (MsgA) preamble based on a Random Access Channel (RACH) configuration for the RRC inactive data transmission; transmitting, via the communication circuitry a message 3 (Msg3) or a MsgA Physical Uplink Shared Channel (PUSCH) comprising uplink (UL) data via configured resources; and receiving, via the communication circuitry, a message 4 (Msg4) or a message B (MsgB) in response to the Msg3 or the MsgA PUSCH.

Abstract: Apparatuses, systems, and methods for performing network slice quota management. A network slice quota management function may store capacity information for one or more network slices. The network slice quota management function may receive a request for an indication of whether a network slice has additional capacity. The network slice quota management function may provide an indication of whether the network slice has additional capacity in response to the request. The capacity information may relate to the capacity of the network slice with respect to the number of wireless devices registered for the network slice, or to the capacity of the network slice with respect to the number of packet sessions established with the network slice, or both, among various possibilities.

Abstract: A user equipment (UE) device may reside in a state of dual connectivity with a master cell group (MCG) and a secondary cell group (SCG), wherein the radio access technologies of the MCG and the SCG are different. While in the dual connectivity state, the UE device may transition to a mode of reduced activity (e.g., processing and/or RF activity) relative to the secondary cell group (SCG) in order to save power, e.g., when traffic flow via the SCG is below a threshold, or when scheduling activity on the SCG is low. Various mechanisms may be employed to reduce activity, e.g., mechanisms such as reduction of beam monitoring, deactivation of secondary cells of the SCG, reduction of number of active antenna elements, employment of longer periods for periodic measurement and reporting processes, etc.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods to implement mechanisms for non-stand-alone unlicensed band cells that support single carrier capable UEs. A UE may camp on a licensed band cell of a RAN and transmit a request to connect. The UE may receive, from the licensed band cell, a connection setup message indicating a switch to an unlicensed band cell of the RAN and receive, from the unlicensed band cell, a reference signal. The UE may transmit to the unlicensed band cell and in response to confirming, based at least in part of the reference signal, radio quality and/or downlink timing of the unlicensed band cell, a connection complete/connection resume message.

Abstract: A user equipment (UE) includes first and second subscriber identity modules (SIMs), possibly subscribed to different carriers. When the first SIM is in a connected state and the second SIM is in an idle state, the UE may need to periodically tune away a radio from a first frequency used for communication under the first SIM to a second frequency used for idle mode activity under the second SIM. The UE may provide to the network of the first SIM the second SIMs traffic activity pattern and/or serving frequency so that the network may provide coordinated configuration and/or scheduling for the UE device, e.g., in order to make the action of tuning away (and tuning back) the radio more efficient and/or to decrease the network impact of such radio tune aways (e.g., to decrease wasted uplink scheduling and wasted downlink transmissions for the first SIM).

Abstract: This disclosure relates to detecting duplicate public warning system messages in a cellular communication system. A wireless device may receive a public warning system indication from a cellular base station during a paging occasion. The public warning system indication may indicate that system information provided by the cellular base station includes a public warning system message. The wireless device may determine whether the public warning system message is a duplicate public warning system message. The wireless device may determine whether to decode the system information including the public warning system message based at least in part on whether the public warning system message is a duplicate public warning system message. The system information including the public warning system message may not be decoded if the public warning system message is determined to be a duplicate public warning system message.
