[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This patent application claims priority to Indian Provisional Patent No. 202041021596, filed on May 22, 2020, entitled “DETECTING HIGH PRIORITY PAGING MESSAGES FOR A USER EQUIPMENT WITH MULTIPLE SUBSCRIPTIONS,” and assigned to the assignee of the present application. The disclosure of the prior application is considered a part of and is incorporated by reference in its entirety into the present patent application. Technical Field
[0003] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for detecting high priority paging messages for user equipment with multiple subscriptions. Background Art
[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).
[0005] A wireless network may include multiple base stations (BSs) capable of supporting communications for multiple user equipment (UEs). A UE may communicate with a BS via a downlink and an uplink. A "downlink" (or forward link) refers to the communication link from the BS to the UE, while an "uplink" (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, etc.
[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at the city, country, region, and even global levels. NR (also known as 5G) is an enhancement set of the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with a cyclic prefix (CP) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL) to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards, as well as support beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to grow, further improvements in LTE, NR, and other radio access technologies remain useful. Summary of the Invention

[0026] The various aspects of the present disclosure will be described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms, and the present disclosure should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, these aspects are provided so that the present disclosure will become comprehensive and complete, and these aspects will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings of this article, it should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is realized independently of any other aspect of the present disclosure or realized in combination with any other aspect of the present disclosure.

It should be understood that any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.
[0027] Several aspects of telecommunications systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.
[0028] It should be noted that while various aspects may be described herein using terminology generally associated with 5G or NR radio access technologies (RATs), various aspects of the present disclosure may be applicable to other RATs, such as 3G RATs, 4G RATs, and / or post-5G RATs (e.g., 6G).
[0029] Figure 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, etc. The wireless network 100 may include multiple base stations 110 (shown as BS110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of a BS and / or a BS subsystem serving this coverage area, depending on the context in which the term is used.
[0030] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or other types of cells. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a Closed Subscriber Group (CSG)). The BS of a macro cell may be referred to as a macro BS. The BS of a pico cell may be referred to as a pico BS. The BS of a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown, BS 110a may be a macro BS for macrocell 102a, BS 110b may be a pico BS for picocell 102b, and BS 110c may be a femto BS for femtocell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB," "base station," "NR BS," "gNB," "TRP," "AP," "Node B," "5G NB," and "cell" may be used interchangeably herein.
[0031] In some aspects, the cells are not necessarily fixed, and the geographic area of the cells may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces (such as direct physical connections or virtual networks) using any suitable transport network.
[0032] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and transmit data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions to other UEs. Figure 1 In the example shown, relay BS 110d may communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay station, relay base station, relay, etc.
[0033] The wireless network 100 may be a heterogeneous network including different types of BSs, such as macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).
[0034] The network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other (eg, directly or indirectly via a wireless or wired backhaul).
[0035] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be fixed or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or apparatus, a biosensor / device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.
[0036] Some UEs may be considered machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. For example, MTC and eMTC UEs include robots, drones, remote devices, sensors, meters, monitors, and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. For example, a wireless node may provide connectivity to or to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs may be considered customer premises equipment (CPE). UE 120 may be included within a housing that houses components of UE 120 (e.g., a processor component and / or a memory component). In some aspects, the processor component and the memory component may be coupled together. For example, the processor component (e.g., one or more processors) and the memory component (e.g., memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.
[0037] In general, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RATs can also be referred to as radio technologies, air interfaces, etc. Frequencies can also be referred to as carriers, frequency channels, etc. In a given geographic area, each frequency can support a single RAT to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.
[0038] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary for communicating with each other). For example, UE 120 can communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, or vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), and / or mesh networks. In this case, UE 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.
[0039] Devices of the wireless network 100 can communicate using an electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc. based on frequency or wavelength. For example, devices of the wireless network 100 can communicate using an operating band having a first frequency range (FR1), which can span from 410 MHz to 7.125 GHz, and / or can communicate using an operating band having a second frequency range (FR2), which can span from 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a "sub-6 GHz" band. Similarly, FR2 is often referred to as a "millimeter wave" band, although different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as a "millimeter wave" band by the International Telecommunication Union (ITU). Thus, unless otherwise specifically stated, it should be understood that the terms "sub-6 GHz," etc., if used herein, can broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specifically stated, it should be understood that the terms "millimeter wave," etc., if used herein, can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.
[0040] As mentioned above, Figure 1 Provided as an example. Other examples can be compared with Figure 1 What is described is different.
[0041] Figure 2is a diagram illustrating an example 200 of base station 110 communicating with UE 120 in wireless network 100 according to the present disclosure. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general T≥1 and R≥1.
[0042] At the base station 110, a transmit processor 220 may receive data for one or more UEs from a data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). A transmit (TX) multiple-input, multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.
[0043] At UE 120, antennas 252a through 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may also process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, etc. In some aspects, one or more components of the UE 120 may be included within the housing 284 .
[0044] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.
[0045] The antennas (e.g., antennas 234a through 234t and / or antennas 252a through 252r) may include, or may be included in, one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, etc. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements coupled to one or more transmit and / or receive components such as Figure 2 One or more antenna elements of one or more components).
[0046] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, and / or CQI) from a controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 (if applicable), further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., with reference to FIG. Figure 4-7 ).
[0047] At base station 110, uplink signals from UE 120 and other UEs may be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 may provide decoded data to a data sink 239 and decoded control information to controller / processor 240. Base station 110 may include a communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include a scheduler 246 to schedule UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of base station 110 may be included in a modem of base station 110. In some aspects, base station 110 includes a transceiver. The transceiver may include any combination of antenna(s) 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., with reference to FIG. Figure 4-7 ).
[0048] As described in more detail elsewhere herein, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component(s) of the base station 110 may perform one or more techniques associated with detecting a high priority paging message for a UE with multiple subscriptions. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component(s) of may perform or direct e.g. Figure 6 The process of 600 Figure 7 The operations of process 700 and / or other processing described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, conversion, and / or interpretation), may cause the one or more processors, UE 120, and / or base station 110 to perform or direct, for example, Figure 6 The process of 600 Figure 7 The operations of process 700 and / or other processes as described herein. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.
[0049] In some aspects, a network node (e.g., base station 110 and / or network controller 130) may include means for transmitting, in association with a first subscription of a UE (e.g., UE 120), an indication of a high priority identifier to be used for paging messages associated with the first subscription, wherein the high priority identifier is associated with the same set of paging occasions as a second identifier assigned to the UE for paging; and / or means for transmitting, in one or more paging occasions associated with the high priority identifier and the second identifier, an indication of whether a high priority paging message for the UE exists, wherein the indication is based at least in part on the high priority identifier. In some aspects, means for the network node to perform the operations described herein may include, for example, one or more of the transmit processor 220, the TX MIMO processor 230, the modulator 232, the antenna 234, the demodulator 232, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246. Additionally or alternatively, means for the network node to perform the operations described herein may include, for example, one or more of the controller / processor 290, the communication unit 294, or the memory 292.
[0050] In some aspects, a UE (e.g., UE 120) includes means for receiving, in association with a first subscription of the UE, an indication of a high priority identifier to be used for a paging message associated with the first subscription, wherein the high priority identifier is associated with the same set of paging occasions as a second identifier assigned to the UE for paging; means for tuning away from a network connection associated with the second subscription of the UE; means for monitoring one or more paging occasions associated with the high priority identifier and the second identifier based at least in part on tuning away from the network connection associated with the second subscription; and / or means for determining whether a high priority paging message for the UE exists based at least in part on monitoring the one or more paging occasions using the high priority identifier. Means for the UE to perform the operations described herein may include, for example, one or more of the antenna 252, the demodulator 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the modulator 254, the controller / processor 280, or the memory 282.
[0051] Although Figure 2 The blocks in FIG. 2 are shown as distinct components, but the functionality described above with respect to the blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.
[0052] As mentioned above, Figure 2 Provided as an example. Other examples may differ from the Figure 2 Examples described.
[0053] Figure 3 3 is a diagram illustrating an example 300 of a multiple subscriber identity module (multi-SIM) UE according to the present disclosure. Figure 3 As shown, UE 120 may be a multi-SIM UE including multiple SIMs (two or more SIMs) (shown as a first SIM 305a and a second SIM 305b). The first SIM 305a may be associated with a first subscription (shown as SUB1), while the second SIM 305b may be associated with a second subscription (shown as SUB2). The subscription may be a subscription with a network operator (e.g., a mobile network operator (MNO)) that enables UE 120 to access a wireless network (e.g., a radio access network (RAN)) associated with the network operator.
[0054] SIM 305 may be a removable SIM (e.g., a SIM card) or an embedded SIM. SIM 305 may include an integrated circuit that securely stores an International Mobile Subscriber Identity (IMSI) and security keys, which are used to identify and authenticate the corresponding subscription associated with SIM 305. In some cases, SIM 305 may store a list of services that UE 120 is allowed to access using the subscription associated with SIM 305, such as data services or voice services.
[0055] like Figure 3 As further shown, the UE 120 can communicate with the first base station 310a via a first cell 315a (shown as cell 1) using the first SIM 305a (e.g., in connected mode, idle mode, or inactive mode). In this case, the first subscription (SUB 1) of the UE 120 can be used to access the first cell 315a (e.g., using the first IMSI for UE identification, using the first security key for UE authentication, using the first list of services that the UE 120 is allowed to access using the first subscription, or by counting data or voice usage of the first subscription on the first cell, etc.). Similarly, the UE 120 can communicate with the second base station 310b via a second cell 315b (shown as cell 2) using the second SIM 305b (e.g., in connected mode, idle mode, or inactive mode). In this case, the second subscription (SUB 2) of UE 120 can be used to access the second cell 315b (e.g., using the second IMSI for UE identification, using the second security key for UE authentication, using a second list of services that UE 120 is allowed to access using the second subscription, or by counting data or voice usage of the second subscription on the second cell, etc.).
[0056] The first base station 310a and / or the second base station 310b may include the above combined Figure 1 One or more of the base stations 110 described herein. Although the first cell 315a and the second cell 315b are shown as being provided by different base stations, in some aspects, the first cell 315a and the second cell 315b can be provided by the same base station. Thus, in some aspects, the first base station 310a and the second base station 310b can be integrated into a single base station.
[0057] In some cases, UE 120 may be capable of operating in a Multi-SIM Multi-Standby (MSMS) mode, such as a Dual-SIM Dual-Standby (DSDS) mode (e.g., when UE 120 is associated with two subscriptions). Additionally or alternatively, UE 120 may be capable of operating in a Multi-SIM Multi-Active (MSMA) mode, such as a Dual-SIM Dual-Active (DSDA) mode (e.g., when UE 120 is associated with two subscriptions).
[0058] In DSDA mode, the UE 120 is capable of concurrent active communications using both SIM cards of the UE 120. Thus, the UE 120 in DSDA mode is capable of communicating using the first SIM card 305a (and the first subscription) while simultaneously communicating using the second SIM card 305b (and the second subscription). For example, when the UE 120 is in an active session (e.g., a voice call or another delay-sensitive service, such as online gaming, stock trading, or an over-the-top (OTT) service) using the first SIM card 305a, the UE 120 is capable of receiving notification of the voice call using the second SIM card 305b without interrupting the communication being conducted using the first SIM card 305a and without tuning or switching away from the first cell 315a to tune to the second cell 315b.
[0059] In DSDS mode, the UE 120 cannot conduct concurrent active communications using both SIMs of the UE 120. Thus, a UE 120 in DSDS mode cannot communicate using the first SIM 305a (and the first subscription) while communicating using the second SIM 305b (and the second subscription). However, the UE 120 in DSDS mode may be able to switch between two separate mobile network services, may include hardware for maintaining multiple connections in a standby state (e.g., one connection per SIM), or may include hardware for maintaining multiple network connections simultaneously (e.g., multiple transceivers), etc. However, the UE 120 in DSDS mode may be able to receive data on only one connection at a time because radio frequency resources are shared between the multiple subscriptions. For example, a UE 120 in DSDS mode may be associated with multiple subscriptions but may include only a single transceiver shared by the multiple subscriptions, a single transmit chain shared by the multiple subscriptions, or a single receive chain shared by the multiple subscriptions, etc.
[0060] In some examples, the UE 120 may be capable of operating in DSDA mode for a first RAT combination and may not be capable of operating in DSDA mode for a second RAT combination. For example, the UE 120 may be capable of operating in DSDA mode for NR+NR, where the first cell 315a (and the first SIM 305a and the first subscription) uses the NR RAT and the second cell 315b (and the second SIM 305b and the second subscription) also uses the NR RAT. However, the UE 120 may not be capable of operating in DSDA mode for NR+LTE, where one of the first cell 315a (and the first SIM 305a and the first subscription) uses the NR RAT and the second cell 315b (and the second SIM 305b and the second subscription) also uses the LTE RAT (or vice versa). In some aspects, the UE 120 may not be capable of operating in DSDA mode for the second RAT combination (e.g., NR+LTE), but the UE 120 may be capable of operating in DSDS mode for the second RAT combination. This UE design reduces design cost compared to enabling the UE 120 to use DSDA mode operation for the second RAT combination.
[0061] As mentioned above, Figure 3 Provided as an example only. Other examples may differ from the Figure 3 The content described.
[0062] In some cases, the UE may be a single receiver (SR) (sometimes also referred to as a single radio) multi-SIM UE, such as an SR-MSMS UE or an SR-DSDS UE, and the like. A multi-SIM UE may be able to switch between two separate mobile network services, may include hardware for maintaining multiple connections (e.g., one connection per SIM) in standby mode, or may include hardware for maintaining multiple network connections simultaneously (e.g., multiple transceivers), and the like. However, an SR-DSDS UE or an SR-MSMS UE may only be able to receive data on one connection at a time because radio frequency resources are shared between multiple subscriptions. For example, an SR-DSDS UE or an SR-MSMS UE may be associated with multiple subscriptions but may only include a single transceiver shared by multiple subscriptions, a single transmit chain shared by multiple subscriptions, or a single receive chain shared by multiple subscriptions, and the like. As a result, the UE may not be able to receive concurrent messages for multiple subscriptions.
[0063] Thus, when the UE is communicating via the first cell using the first subscription associated with the first SIM, the second cell may send a paging message for the second subscription associated with the second SIM. However, the UE may not be able to determine when a paging message requires a response or other attention, and when the paging message can be ignored. Therefore, the UE faces the risk of increased latency by ignoring emergency paging messages, and faces the risk of increased signaling overhead due to duplication of emergency paging information from the second cell. The duplication wastes power and processing resources at the UE and the base station of the second cell, and increases network overhead. Alternatively, the UE wastes power and processing resources when responding to or otherwise processing non-emergency paging messages, and increases delays before the UE returns to a connected state with the first cell.
[0064] Some of the techniques and apparatus described herein enable a UE (e.g., a multi-SIM UE 120) to distinguish between high-priority paging messages and other paging messages associated with a second subscription while tuned away from the first subscription. Thus, the UE 120 saves network and processing resources by ignoring paging messages unless a base station (e.g., the second base station 310b) indicates that the paging message is high priority. By ensuring that the UE 120 responds to the high-priority paging message, the second base station 310b reduces latency and signaling overhead when sending paging messages classified as high priority, and saves power and processing resources.
[0065] Figure 4 4 is a diagram illustrating an example 400 of registration for a UE 120 having multiple subscriptions according to the present disclosure. Figure 4 As shown, the UE 120 may include multiple SIMs (shown as a first SIM 305a and a second SIM 305b, as described above in conjunction with Figure 3 As also described above, a first SIM 305a can be associated with a first subscription (shown as SUB 1), while a second SIM 305b can be associated with a second subscription (shown as SUB 2). Although the description herein focuses on multiple SIMs, the description is similarly applicable to other technologies for associating multiple subscriptions with a UE 120, such as an embedded SIM, a virtual SIM, or additional technologies for storing different IMSIs. Furthermore, although the description herein focuses on two subscriptions, the description is similarly applicable to a UE 120 associated with additional subscriptions (e.g., three subscriptions, four subscriptions, etc.).
[0066] like Figure 4 As further shown above, Figure 3As shown, the UE 120 may communicate with the first base station 310a via the first cell 315a (shown as cell 1) using the first SIM 305a, and the UE 120 may communicate with the second base station 310b via the second cell 315b (shown as cell 2) using the second SIM 305b. Figure 4 , the first base station 310a and the second base station 310b are shown as separate base stations 110, but in some aspects may be integrated into a single base station 110. Although the description herein focuses on a UE 120 communicating with the first base station 310a and / or the second base station 310b, the description similarly applies to a UE 120 communicating with a first core network supporting the first base station 310a and / or a second core network supporting the second base station 310b. For example, the UE 120 may communicate with the first core network and / or the second core network using non-access stratum (NAS) signaling.
[0067] As indicated by reference numeral 405, the UE 120 may send a registration request for the first SIM 305a to the first base station 310a via the first cell 315a. For example, the UE 120 may submit a registration request or other message associated with registration defined in a 3GPP specification and / or another standard.
[0068] In some aspects, the UE 120 may send a request for a high-priority identifier during the registration process. In some aspects, the UE 120 may include the request in an information element of an additional information request or other data element associated with the registration request, as defined in a 3GPP specification and / or another standard. For example, the request may be included in one or more bits (e.g., bit 2, bit 3, etc.) of one or more octets (e.g., octet 3, octet 4, etc.) of the information element of the additional information request. Alternatively, the UE 120 may send the request for a high-priority identifier in a message separate from the registration request. In some aspects, the UE 120 may still send a separate message during the registration process.
[0069] In some aspects, the high priority identifier may comprise a Temporary Mobile Subscriber Identity (TMSI).Alternatively, the high priority identifier may comprise a different high priority UE identifier (UE ID).
[0070] As shown by reference numeral 410, the first base station 310a may assign a high priority identifier to the first SIM 305a based at least in part on receiving a request from the UE 120. In some aspects, the high priority identifier may include the same set of bits as the second identifier assigned to the UE 120 for paging, wherein the same set of bits is used to calculate the UE ID of the UE 120. Thus, the paging occasion associated with the second identifier and the paging occasion associated with the high priority identifier may fall at the same point in time. In some aspects, the first base station 310a may use the high priority TMSI and the second TMSI for the UE such that an expression similar to the following is satisfied:
[0071] (5G-S-TMSI XOR 5G-HP-TMSI)mod 1024=0,
[0072] Wherein, 5G-S-TMSI may represent the second TMSI, and 5G-HP-TMSI may represent the high-priority TMSI. This example expression may ensure that the same 10 bits of the second TMSI and the high-priority TMSI are used to calculate the UE ID associated with the UE 120. In some aspects, the first base station 310a may include more than 10 identical bits or fewer than 10 identical bits in the second TMSI and the high-priority TMSI, where the identical bits are used to calculate the UE ID.
[0073] In some aspects, the high priority identifier can include the same number of bits as the second identifier. For example, the high priority identifier and the second identifier can each include 48 bits. In some aspects, the first base station 310a can include more than 48 bits or fewer than 48 bits in the second identifier and the high priority identifier. Additionally or alternatively, the high priority identifier can be unique to the UE 120 within the tracking area. For example, the tracking area can include all or a portion of the first cell 315a. In some aspects, the tracking area can additionally or alternatively include all or a portion of the second cell 315b and / or other additional cells.
[0074] As indicated by reference numeral 415, base station 310a may transmit, in association with a first subscription of UE 120, a high priority identifier to be used for a paging message associated with the first subscription, and UE 120 may receive, in association with the first subscription of UE 120, a high priority identifier to be used for a paging message associated with the first subscription. As described above, the high priority identifier may be associated with the same set of paging occasions as the second identifier assigned to the UE for paging.
[0075] In some aspects, such as Figure 4As shown, the first base station 310a can send the high priority identifier based at least in part on receiving a request for the high priority identifier from UE120 during the registration process. Therefore, UE 120 can receive the high priority identifier based at least in part on sending the request. For example, the first base station 310a can include the high priority identifier in a registration accept message or other messages associated with registration defined in the 3GPP specification and / or another standard. For example, the high priority identifier can be included in one or more octets (e.g., octets 7 to 10, octets 8 to 10, etc.) of the registration accept message. As an alternative, the first base station 310a can send the high priority identifier in a message separate from the registration accept message. In some aspects, the first base station 310a can still send a separate message during the registration process.
[0076] Although the first SIM 305a is depicted as being registered with the first base station 310a, Figure 4 The operations depicted in FIG1 may additionally or alternatively include registering the second SIM 305b with the second base station 310b. For example, the UE 120 may send a registration request for the second SIM 305b to the second base station 310b via the second cell 315b; the second base station 310b may assign a high priority identifier to the second SIM 305b based at least in part on receiving the request from the UE 120; and the UE 120 may receive, in association with the second subscription of the UE 120, the high priority identifier to be used for paging messages associated with the second subscription.
[0077] In some aspects, the first base station 310a can use a high-priority identifier to indicate when a paging message from the first SIM 305a requires a response or other attention. This conserves network resources by reducing the need for the first base station 310a to repeat paging messages when a response or other attention is required. The UE 120 can also determine when a paging message from the first base station 310a can be ignored. This conserves power and processing resources for the UE 120 when a paging message does not require a response or other action from the UE 120.
[0078] As mentioned above, Figure 4 are provided as examples. Other examples may differ from those described in Figure 4 The content described.
[0079] Figure 5 is a diagram illustrating an example 500 of detecting a high priority paging message for a UE with multiple subscriptions according to the present disclosure. Figure 5An example call flow is shown in which UE 120 receives a paging message from a first cell 315a associated with a first subscription of UE 120 and determines whether to respond or otherwise act on the paging message. Figure 5 As shown, UE 120 may be a multi-SIM UE including multiple SIMs 305 and multiple subscriptions. Although the description herein focuses on multiple SIMs, the description is similarly applicable to other technologies for associating multiple subscriptions with UE 120, such as embedded SIMs, virtual SIMs, or additional technologies for storing different IMSIs. Furthermore, although the description herein focuses on two subscriptions, the description is similarly applicable to UE 120 associated with additional subscriptions (e.g., three subscriptions, four subscriptions, etc.).
[0080] like Figure 4 As further shown, the UE 120 may communicate with the first base station 310a via the first cell 315a (shown as cell 1) using the first SIM 305a, and the UE 120 may communicate with the second base station 310b via the second cell 315b (shown as cell 2) using the second SIM 305b, as described above in conjunction with Figure 4 As stated. Figure 5 , the first base station 310a and the second base station 310b are shown as separate base stations 110, but in some aspects may be integrated into a single base station 110. Although the description herein focuses on a UE 120 communicating with the first base station 310a and / or the second base station 310b, the description similarly applies to a UE 120 communicating with a first core network supporting the first base station 310a and / or a second core network supporting the second base station 310b. For example, the UE 120 may communicate with the first core network and / or the second core network using NAS signaling.
[0081] As indicated by reference numeral 505, the UE 120 may be active on a network connection associated with a second subscription of the UE 120. For example, the UE 120 may communicate with the second base station 310b via the second cell 315b.
[0082] As shown at reference numeral 510, UE 120 may tune away from a network connection associated with a second subscription of UE 120. For example, UE 120 may tune away from a connection with second base station 310b. In some aspects, UE 120 may coordinate with first base station 310a and / or second base station 310b to configure the tune away.
[0083] As indicated by reference numeral 515, UE 120 may monitor one or more paging occasions associated with the high priority identifier and the second identifier based at least in part on tuning away from the network connection associated with the second subscription. For example, the high priority identifier and / or the second identifier may have been assigned to UE 120 during a registration process with first base station 310a (e.g., as described above in connection with Figure 4 Additionally or alternatively, separate from the registration process, the high priority identifier and / or the second identifier may have been assigned to the UE 120 during communication with the first base station 310a.
[0084] As further shown by reference numeral 515, the first base station 310a may transmit an indication of whether a high priority paging message is present for the UE 120 in one or more paging occasions associated with the high priority identifier and the second identifier. The indication may be based at least in part on the high priority identifier. For example, as described below, the indication may be included in downlink control information (DCI) including a short message and / or a physical downlink shared channel (PDSCH) communication scheduled by the DCI, wherein the short message includes the indication, and wherein the paging record in the PDSCH communication satisfies a condition associated with the high priority identifier.
[0085] The UE 120 may use the high priority identifier to determine whether there is a high priority paging message for the UE 120 based at least in part on monitoring one or more paging occasions. For example, the UE 120 may have received (e.g., sent from the first base station 310a) in association with a first subscription of the UE 120 a high priority identifier to be used for paging messages associated with the first subscription, where the high priority identifier is associated with the same set of paging occasions as the second identifier assigned to the UE 120 for paging. In some aspects, the UE 120 may have sent a request for the high priority identifier during a registration process and received the high priority identifier based at least in part on sending the request (e.g., as described above in connection with Figure 4 Additionally or alternatively, as described above, separate from the registration process, the UE 120 may have sent a request for a high priority identifier during communication with the first base station 310a.
[0086] In some aspects (e.g., as described above in conjunction with Figure 4 As described above), the high priority identifier and the second identifier may include the same set of bits used to calculate the UE identifier of the UE 120 used for paging. Additionally or alternatively (e.g., as described above in conjunction with Figure 4 As described above, the high priority identifier may include the same number of bits as the second identifier and may be unique to the UE 120 within the tracking area.
[0087] In some aspects, the UE 120 may determine whether a high priority paging message is present for the UE 120 based at least in part on receiving a DCI including a short message (e.g., scrambled using a paging radio network temporary identifier (P-RNTI)) and determining that the short message includes an indication of a high priority paging message. For example, a single bit of the short message may indicate whether the high priority paging message is present in a paging record. In some aspects, the single bit may include a third bit or other bit of a DCI format 1_0 or other DCI format as defined in a 3GPP specification and / or another standard. For example, the third bit or other bit may be set to 1 to indicate that a high priority paging message is present in a paging record. Similarly, the third bit or other bit may be set to 0 to indicate that a high priority paging message is not present in a paging record.
[0088] In some aspects, the UE 120 may also decode a PDSCH communication scheduled by the DCI based at least in part on determining that the short message includes an indication of a high priority paging message, and determine that a paging record in the PDSCH communication satisfies a condition associated with a high priority identifier. For example, as described above, the base station 310a may send a DCI (e.g., a DCI scrambled using a P-RNTI) including a short message, wherein the short message includes an indication of a high priority paging message; and send a PDSCH communication scheduled by the DCI, wherein the paging record in the PDSCH communication satisfies a condition associated with a high priority identifier. In some aspects, the condition is that the paging record includes a UE ID that matches the high priority identifier. For example, as described above with respect to Figure 4 As explained, the UE ID may be determined based at least in part on the high priority identifier.
[0089] In some aspects, regardless of whether the short message includes an indication of a high-priority paging message, the UE 120 may decode the PDSCH communication scheduled by the DCI. For example, the UE 120 may decode the PDSCH communication scheduled by the DCI and determine whether there is a high-priority paging message for the UE 120 based at least in part on whether a paging record in the PDSCH communication satisfies a condition associated with the high-priority identifier. In some aspects, as described above, the condition is that the paging record includes a UE identifier that matches the high-priority identifier.
[0090] Alternatively, the base station 310a may transmit a short message included in the DCI (e.g., scrambled using the P-RNTI), the short message including an indication that the high-priority paging message is not present in a paging record included in the PDSCH communication scheduled by the DCI; and / or transmit the paging record, wherein the paging record does not include a UE identifier that matches the high-priority identifier. Thus, at reference numeral 520, the UE 120 may ignore one or more paging messages based at least in part on a determination that there are no high-priority paging messages for the UE 120. For example, the UE 120 may determine that the short message included in the DCI (e.g., scrambled using the P-RNTI) includes an indication that the high-priority paging message is not present in a paging record included in the PDSCH communication scheduled by the DCI; and / or determine that the paging record does not include a UE identifier that matches the high-priority identifier. In some aspects, the UE 120 may also determine not to decode PDSCH communications scheduled by the UE 120 when the short message includes an indication that a high priority paging message is not present in the paging record.
[0091] As indicated by reference numeral 520, UE 120 may determine whether to respond to the paging message or otherwise act on the paging message. For example, UE 120 may determine whether to respond to the paging message or otherwise act on the paging message based at least in part on the short message including an indication that a high priority paging message is present in the paging record and / or the paging record in the PDSCH communication meeting a condition associated with the high priority identifier.
[0092] For example, as shown at reference numeral 525a, UE 120 may respond to the high priority paging message based at least in part on a determination that there is a high priority paging message for the UE. For example, as shown at reference numeral 530, UE 120 may respond using a physical uplink shared channel (PUSCH) communication corresponding to a PDSCH communication or using another uplink communication sent to the first base station 310a.
[0093] Additionally or alternatively, as indicated by reference numeral 525b, the UE 120 may suspend the network connection associated with the second subscription and establish the network connection associated with the first subscription based at least in part on the determination that there is a high priority paging message for the UE 120. For example, as indicated by reference numeral 535, the UE 120 may suspend communication with the second base station 310b via the second cell 315b and establish communication with the first base station 310a via the first cell 315a as indicated by reference numeral 540.
[0094] Although the UE 120 is depicted as determining whether to respond to the paging message or otherwise process the paging message from the first base station 310a for the first SIM 305a, Figure 5 The operations depicted in the foregoing may additionally or alternatively include the UE 120 determining whether to respond to the paging message or otherwise process the paging message from the second base station 310b for the second SIM 305b. For example, the UE 120 may tune away from a network connection associated with the UE 120's first subscription and monitor one or more paging occasions associated with the high-priority identifier and the second identifier based at least in part on tuning away from the network connection associated with the first subscription; the second base station 310b may send an indication of whether a high-priority paging message for the UE 120 exists in the one or more paging occasions associated with the high-priority identifier and the second identifier; and the UE 120 may use the high-priority identifier to determine whether a high-priority paging message for the UE 120 exists based at least in part on monitoring the one or more paging occasions. In this example, the UE 120 may ignore the one or more paging messages received from the second base station 310b based at least in part on the determination that there is no high-priority paging message for the UE 120. Alternatively, the UE 120 may respond to or otherwise process the high priority paging message received from the second base station 310b based at least in part on a determination that there is a high priority paging message for the UE 120 .
[0095] By using the combination Figure 5 Using the described techniques, UE 120 can determine whether a paging message associated with the second subscription and received while tuned away from the first subscription is of high priority. As a result, the UE saves power and processing resources by ignoring non-emergency paging messages. At the same time, by indicating that the paging message is of high priority, base station 310a saves network overhead as well as processing resources and power that would otherwise be used to repeatedly send paging messages to UE 120.
[0096] As mentioned above, Figure 5 Provided as an example only. Other examples may differ from the Figure 5 An example of description.
