Abstract: A method is disclosed where a user equipment (“UE”) determines that the UE is in a connected mode. The UE then determines a connection type of the connected mode and prioritizes a measurement report based on the connection type. The method may also be performed by an integrated circuit of the UE.

Abstract: A UE in an RRC inactive state may determine an operational state mismatch between an actual RRC operational state for the UE and a stored RRC operational state for the UE maintained at a network node. To determine the mismatch, while the UE is in the RRC inactive state, the UE may monitor at least one of paging messages, serving cell power levels, or neighbor cell power levels. When an operational state mismatch is detected, the UE may initiate a state correction procedure rather than an RRC resume procedure.

Abstract: Disclosed are embodiments for reducing likelihood of selecting a cell identified by a Radio Access Network (RAN) Notification Area ID (RNA ID) that is different from that identifying a last or current serving cell so as to avoid an RNA update procedure; reducing Random Access Channel (RACH) transmissions for an RNA update procedure and a mobile originated (MO) data transmission in response to a Radio Resource Control (RRC) triggered RNA update procedure; and selecting a band or beam in a multi-band/beam cellular system that improves RACH efficiency.

Abstract: A user equipment (UE) passively determines the presence of a cellular network bottleneck in a downlink channel and may take appropriate actions to mitigate the bottleneck. The UE may analyze the transport block size (TBS) of slots of received downlink traffic and assign states the to various slots based on this analysis. Based on these assigned states, the UE may identify a burst of network traffic from network traffic received from the cellular network, and the UE may also determine the burst duration as well as a busy estimation. The UE may determine that the cellular network is experiencing a bottleneck based at least in part on the burst duration and the busy estimation.

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: Apparatuses, systems, and methods for high data mode operation in cellular networks. A UE may determine, for an interface to a high-speed cellular network, a categorization from a plurality of categorizations, determine availability of the high-speed cellular network, and select, based at least in part on the categorization and availability of the high-speed cellular network, the interface for a data connection to the high-speed cellular network. The categorization may be one of expensive or not expensive and/or one of a first level associated with a higher compression codec rate or a second level associated with a lower compression codec rate. The UE may receive, from one of the a low-speed cellular network or the high-speed cellular network, carrier plan information for a cellular data service carrier and analyze the carrier plan information to determine desirability of a switch, e.g., from the low-speed cellular network to the high-speed cellular network.

Abstract: Techniques discussed herein can reduce RRC signaling messages, and various aspects can employ one or more of these sets of techniques. A first set of techniques can be employed to reduce RACH (Random Access Channel) requests from a RRC Idle State SIM (Subscriber Identity Module) of a UE in DSDS (Dual SIM Dual Standby) mode. A second set of techniques can be employed to reduce the number of RACH attempts to obtain NotBroadcasted (e.g., On Demand) SI(s) (System Information(s)) by a UE in response to a page message indicating SI modification.

Abstract: This disclosure relates to performing implicit radio resource control state transitions in a cellular communication system. A wireless device may establish a radio resource control (RRC) connection with a cellular base station. A data inactivity timer length and a target RRC state for implicit RRC transitions may be determined. A data inactivity timer having the determined data inactivity timer length may be initiated. It may be determined that the data inactivity timer has expired. The wireless device may transition to the target RRC state based at least in part on determining that the data inactivity timer has expired.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to prioritize cells that support EN-DC over similar cells not supporting EN-DC. The UE may be configured to perform one or more measurement scans associated with cell selection and/or cell re-selection and may determine whether at least two LTE cells meet a selection criteria based on RSRP and/or SNR measurements. The UE may be configured to, in response to determining that at least two LTE cells meet the selection criteria, prioritize a first LTE cell of the at least two LTE cells over a second LTE cell of the at least two LTE cells based, at least in part, on support EN-DC. The first LTE cell may indicate support of EN-DC, e.g., via a ULI IE included in a SIB2 broadcast by the first LTE cell. The UE may be configured to select the first LTE cell for camping.
