A multi-universal subscriber identity module (MUSIM) user equipment (UE) is configured to stay synchronized with a network. The UE registers to a first network for the first SIM, registering to a second network for the second SIM, prior to the UE conducting a high priority activity related to the second SIM, sends, to the first network via a connection associated with the first SIM, a first message comprising an estimated time duration during which the UE conducts the high priority activity related to the second SIM, receives, from the first network, a second message indicating a time period during which the first network will retain a connection context for the connection associated with the first SIM in an RRC Inactive state and when the UE completes the high priority activity, determines the connection context of the first network for the connection associated with the first SIM.

Synchronization of RRC status of a multi-SIM user equipment with a base station

A user equipment (UE) is configured to enter a radio resource control (RRC) CONNECTED state on a first network using a first subscriber identification module (SIM) and an RRC INACTIVE or RRC IDLE state on a second network using a second SIM, transmit, to the first network, a request for a scheduling gap (SG) configuration, wherein, during a duration of the SG, the first network avoids scheduling resources for the UE, receive, from the first network, an indication of the SG configuration to be used, during the duration of the SG, tune away from the first network to perform operations on the second network and after the duration of the SG, tune back to the first network, wherein the RRC CONNECTED state is maintained on the first network during the duration of the SG.

Multi-SIM scheduling gaps

Devices and associated methods for operating a dual-subscriber identity module (SIM) dual-standby (DSDS) user equipment device (UE) configured with a first SIM and a second SIM. The UE transmits a connection request message to a base station over a first network using the first SIM, where the connection request message includes one or more capability indications of the UE. The UE receives a connection accept message from the base station, where the connection accept message includes one or more network capability indications corresponding to respective UE capability indications of the one or more UE capability indications. The UE performs communications with the base station according to the one or more network capability indications.

Multi-SIM UE capability indications and band conflict resolution

Systems, apparatus and methods enable layer 2 (L2) relaying optimizations for a remote user equipment (UE) to receive system information (SI) from a relay UE. The relay UE may establish a sidelink communication channel with the remote UE that is in a radio resource control (RRC) idle state, an RRC inactive state, or an out-of-coverage (OOC) state with respect to the base station. The relay UE decodes a relay SI request received through the sidelink communication channel from the first remote UE. The relay SI request indicates requested system information. The Relay UE obtains the requested system information or a subset of the requested system information from a memory device or from the base station and encodes a relay SI response to send to the first remote UE. The relay SI response includes the requested system information or the subset of the requested system information.

Enhanced wake-up signal based power saving for a wireless device

Determining RRC processing delays for multi-subscriber identify module (MSIM) user equipments (UEs) may include decoding a capabilities message from a UE that indicates the UE is an MSIM UE that includes at least a first SIM and a second SIM. A communication for the first SIM of the UE may be encoded. The communication may be configured to cause the UE to perform a radio resource control (RRC) procedure. A transmission request received from the UE may be decoded. The transmission request may be associated with the RRC procedure. In response to receiving the transmission request, an uplink (UL) gram may be scheduled for the first SIM of the UE.

RRC processing delays associated with multi-sim UES

A method for power saving, comprising: establishing a radio resource control (RRC) connection with a wireless device, transmitting, to the wireless device, configuration information indicating a discontinuous reception (DRX) cycle time, a DRX on time period, and an offset time, transmitting an enhanced wake-up signal (EWUS) monitoring occasion for a DRX cycle, the EWUS monitoring occasion based on the offset time and the DRX on time period, determining that the wireless device can skip monitoring one or more future EWUS monitoring occasions, transmitting, during a first DRX cycle, a EWUS for the wireless device during the EWUS monitoring occasion associated with the first DRX cycle, the EWUS indicating that the wireless device can skip the one or more future EWUS monitoring occasions, and skipping transmitting the EWUS to the wireless device during the one or more future EWUS monitoring occasions.

In another aspect, a technique for a wireless system to receive a multi-SIM capability message from a wireless device, determine a connection configuration of the wireless device based on the received multi-SIM capability message, and transmit an indication of the configured connection to the wireless device.

Multi-subscriber identity module capability signaling framework

An apparatus of a node of a network comprises one or more baseband processors to process a first user equipment (UE) capability report from a first UE, and to process a second UE capability report from a second UE, wherein the first UE capability report and the second UE capability report include a same UE capability ID for the first UE and the second UE, and wherein the first capability report includes partial UE capability information for the first UE and the second capability report includes partial UE capability information for the second UE. The apparatus can include a memory to store the first capability report and the second capability report.

Self-learning UE capability verification from partial reported capabilities

Coordinated leaving for a UE having a first SIM and a second SIM may include decoding, at a baseband processor, an RRC reconfiguration message associated with the first SIM received from a first network. A communication corresponding to the second SIM received from a second network is decoded while the baseband processor is processing the received RRC reconfiguration message. The communication received from the second network is determined to comprise a higher priority than the RRC reconfiguration procedure. Based on determining, a UAI message corresponding to the first SIM is encoded by the baseband processor for transmission to the first network. The UAI message is configured to inform the first network of coordinated leaving and abortion of the RRC reconfiguration procedure. The first SIM is transitioned to an idle mode. An RRC request corresponding to the second SIM is encoded by the baseband processor for transmission to the second network.

Apparatuses, systems, and methods are provided for managing UE upgrade requests using UE assistance information (UAI), including network controlled upgrade support, UE initiated upgrade requests, and/or budget based upgrade requests.

UE power saving in NR using UE assistance information

Briefly, in accordance with one or more embodiments, an apparatus of a user equipment (UE), comprises one or more baseband processors to derive a dynamic scrambling key, and a memory to store the dynamic scrambling key and a temporary UE identifier (temporary UE ID) assigned to the UE. The one or more baseband processors monitor a paging request for a scrambled UE identifier (UE ID) to determine if the paging request is intended for the UE by unscrambling the scrambled UE ID with the dynamic scrambling key to produce the temporary UE ID. The paging request is intended for the UE if the temporary UE ID produced by unscrambling the scrambled UE ID matches the temporary UE ID stored in the memory. A new dynamic scrambling key may be derived each time the UE returns to a radio resource control idle (RRC_IDLE) state.

Security for paging messages

Techniques described herein may be used to enable User Equipment (UE) to efficiently and reliably report supported band combinations to a wireless network. An enhanced NodeB (eNB) may determine eNB-supported bands combinations for carrier aggregation scenarios, create a simplified representation of the eNB-supported bands combinations (e.g., using a highest order band combination, groups of band combinations, etc.), and communicate the eNB-supported bands combinations to the UE. The UE may determine UE-supported band combinations that are among the eNB-supported bands combinations, create a simplified representation of the UE-supported band combinations, and communicate the eNB-supported bands combinations to the eNB. The eNB may use the UE-supported band combinations to allocate appropriate carriers to the UE for carrier aggregation.

Downlink spectral capacity of an eMBMS cell to be maximized for the eMBMS users. In one embodiment, supplementary eMBMS cells may be used together with a primary cell, in which the supplementary eMBMS cells broadcast only eMBMS content and the primary cell is used for uplink and downlink signaling. The primary cell may perform signaling for the corresponding supplementary cells. In this manner, signaling relating to configuring of the eMBMS cells may be offloaded to the non-eMBMS primary cell and eMBMS specific services can be fully utilized from the eMBMS cells. In a second embodiment, an eMBMS cell may be a standalone eMBMS cell that is not associated with a primary cell. In this embodiment, self-contained eMBMS signaling is defined. Additionally, eMBMS data may be broadcast in specified MBSN subframes. In this manner, a device, such as an eMBMS-only device, can independently receive eMBMS services.
