The method also includes receiving, from the first network, a second message. The second message can configure a measurement gap, reconfigure a measurement gap, or release a measurement gap. The second message can also suspend data communication from the UE during the configured measurement gap. The method additionally includes suspending communication with the first network during the configured measurement gap. The communication can be suspended to conserve power, tune away a multi-subscriber identity module (MSIM) of the UE, or measure a neighboring cell.

[0002] This application claims priority to U.S. Patent Application No. 17 / 317,784, filed May 11, 2021, entitled “USER EQUIPMENT (UE) NEW RADIO (NR) MEASUREMENT GAP REQUEST AND RELEASE FOR POWER SAVINGS AND MULTIPLESUBSCRIBER IDENTITY MODULE (MSIM) MEASUREMENTS,” which claims priority to U.S. Patent Application No. 17 / 317,784, filed July 10, 2020, entitled “USER EQUIPMENT (UE) NEWRADIO (NR) MEASUREMENT GAP REQUEST AND RELEASE FOR POWER SAVINGS AND MULTIPLESUBSCRIBER IDENTITY MODULE (MSIM).” The benefit of U.S. Provisional Patent Application No. 63 / 050,718, entitled “MEASUREMENTS (User Equipment (UE) New Radio (NR) Measurement Gap Requests and Releases for Power Saving and Multi-Subscriber Identity Module (MSIM) Measurements),” the disclosure of which is expressly incorporated herein by reference in its entirety. Technical Field

[0003] Various aspects of this disclosure generally relate to wireless communications, and more particularly to techniques and apparatus for user equipment (UE) auxiliary measurement gap request and release for power saving and multi-subscriber identity module (MSIM) measurements. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power). 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 an enhancement set of the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

[0005] Wireless communication networks may include several base stations (BSs) capable of supporting communication between several user equipments (UEs). UEs can communicate with the base stations (BSs) via downlinks and uplinks. 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, a BS may be referred to as a B-node, gNB, access point (AP), radio headend, transmit / receive point (TRP), new radio (NR) BS, 5G B-node, etc.

[0006] The above multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different user equipment to communicate at the city, country, region, and even global levels. New Radio (NR) (also known as 5G) is an enhancement set to the LTE mobile standard issued by the 3rd Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by using Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) on the downlink (DL), CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation to improve spectral efficiency, reduce costs, improve service, utilize new spectrum, and better integrate with other open standards.

[0025] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be implemented in many different forms and should not be construed as being limited to any specific structure or function given throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Based on these teachings, those skilled in the art will appreciate that the scope of this disclosure is intended to cover any aspect of the disclosure described herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, any number of the aspects set forth may be used to implement an apparatus or method of practice. Furthermore, the scope of this disclosure is intended to cover such apparatus or methods practiced using additional structures, functionalities, or structures and functionalities that complement or supplement the various aspects of this disclosure set forth. It should be understood that any aspect of this disclosure disclosed may be implemented by one or more elements of the claims.

[0026] Several aspects of a telecommunications system will now be described with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and explained 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.

[0027] It should be noted that while the aspects may be described using terms commonly associated with 5G and next-generation wireless technologies, the aspects of this disclosure may be applied in communication systems based on other generations, such as and including 3G and / or 4G technologies.

[0028] It is desirable for the User Equipment (UE) to provide auxiliary information for configuring one or more elements of a measurement gap. Aspects of this disclosure relate to UE-assisted measurement gap requests and releases. As an example, the UE may transmit measurement gap requests and / or measurement gap releases to perform measurements, deactivate a SIM in a multi-subscriber identity module (SIM) configuration, and / or save power.

[0029] In one configuration, the UE transmits a first message to a first network (e.g., an LTE network) including measurement gap configuration, measurement gap reconfiguration, selection from a measurement gap pool, or measurement gap release. The UE may receive a second message from the first network, which configures, reconfigures, releases, or indicates selection from a measurement gap pool. The second message may also suspend data communication from the UE during the configured measurement gap. The UE may suspend communication with the first network during the configured measurement gap. Communication may be suspended for power saving, multi-subscriber identity module (MSIM) decoupling, or measurement of neighboring cells.

[0030] Figure 1 This is a diagram illustrating a network 100 in which various aspects of this disclosure can be practiced. Network 100 can be a 5G or NR network or some other wireless network, such as an LTE network. Wireless network 100 may include several BS 110s (shown as BS110a, BS110b, BS110c, and BS110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, B-node, gNB, 5G B-node (NB), access point, transmit / receive point (TRP), etc. Each BS can provide communication coverage for a specific geographic area. In 3GPP, the term "cell" can refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0031] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. Macrocells can cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access by UEs with a service subscription. Picocells can cover a relatively small geographic area and allow unrestricted access by UEs with a service subscription. Femtocells can cover a relatively small geographic area (e.g., a residential area) and allow restricted access by UEs associated with that femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS used for macrocells may be referred to as a macro BS. A BS used for picocells may be referred to as a pico BS. A BS used for femtocells may be referred to as a femto BS or a home BS. Figure 1In the example shown, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “B node (NB),” “5G NB,” and “cell” are used interchangeably.

[0032] In some respects, the cell may not be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile BS. In some respects, BSs may interconnect with each other and / or interconnect to one or more other BSs or network nodes (not shown) in the wireless network 100 using any suitable transport network through various types of backhaul interfaces (such as direct physical connections, virtual networks, etc.).

[0033] The wireless network 100 may also include a relay station. A relay station is an entity capable of receiving data transmissions from an upstream station (e.g., a BS or a UE) and transmitting those data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE capable of relaying transmissions for other UEs. Figure 1 In the example shown, relay station 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay station may also be referred to as a relay BS, relay base station, relay, etc.

[0034] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) (e.g., 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 effects on interference in wireless network 100. For example, macro BSs may have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 watts).

[0035] As an example, BS 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and core network 130 may exchange communication via backhaul link 132 (e.g., S1, etc.). Base station 110 may communicate with each other directly or indirectly (e.g., via core network 130) on other backhaul links (e.g., X2, etc.).

[0036] Core network 130 may be an evolved packet core (EPC), which may include at least one mobility management entity (MME), at least one serving gateway (S-GW), and at least one packet data network (PDN) gateway (P-GW). The MME may be the control node that handles signaling between UE 120 and the EPC. All user IP packets can be transmitted through the S-GW, which itself can connect to the P-GW. The P-GW provides IP address allocation and other functions. The P-GW can connect to the network operator's IP services. The operator's IP services may include the Internet, intranet, IP Multimedia Subsystem (IMS), and packet switching (PS) streaming services.

[0037] Core network 130 provides user authentication, access authorization, tracking, IP connectivity, and other access, routing, or mobility functions. One or more of base stations 110 or access node controllers (ANCs) can interface with core network 130 via backhaul links 132 (e.g., S1, S2, etc.) and can perform radio configuration and scheduling for communication with UE 120. In some configurations, the various functions of each access network entity or base station 110 can be distributed across various network devices (e.g., radio headends and access network controllers) or combined into a single network device (e.g., base station 110).

[0038] UE 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be stationary or mobile. UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE may be a cellular phone (e.g., a smartphone), personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet, camera, gaming device, netbook, smartbook, ultrabook, medical device or equipment, biometric sensor / device, wearable device (e.g., smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), entertainment device (e.g., music or video device, or satellite radio), vehicle component or sensor, smart meter / sensor, industrial manufacturing equipment, GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0039] UE 120 may include a measurement gap assist module 140. For simplicity, only one UE 120d is shown as including the measurement gap assist module 140. The measurement gap assist module 140 may transmit a first message to a first radio access technology (RAT) including a first measurement gap configuration, measurement gap reconfiguration, selection from a measurement gap pool, or measurement gap release. The measurement gap assist module 140 may also receive a second message from the first RAT for configuring, reconfiguring, or releasing a measurement gap. The second message may also be configured to suspend data communications from the UE during a configured measurement gap. The measurement gap assist module 140 may also suspend communications with the first RAT during a configured measurement gap. Communications may be suspended to save power, perform multi-subscriber identity module (MSIM) disconnection, and / or measure neighboring cells.

[0040] Base station 110 may include a measurement gap module 138 for transmitting a first message including a measurement gap configuration to user equipment (UE) 120. Measurement gap module 138 may be configured to receive a second message from UE 120. Measurement gap module 138 may also be configured to transmit a third message including a measurement gap release to UE 120.

[0041] Some UEs can be considered Machine-Type Communication (MTC) UEs, or evolved or enhanced Machine-Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which can communicate with a base station, another device (e.g., a remote device), or some other entity. Wireless nodes can provide connectivity to or to a network (e.g., a wide area network such as the Internet) or a cellular network, for example, via wired or wireless communication links. Some UEs can be considered Internet of Things (IoT) devices, and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included inside a housing that houses the components of UE 120, such as processor components, memory components, etc.

[0042] Generally, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific Radio Access Technology (RAT) and can operate on one or more frequencies. A RAT may also be referred to as a radio technology, air interface, etc. A frequency may also be referred to as a carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5GRAT networks can be deployed.

[0043] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In this scenario, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere as being performed by base station 110. For example, base station 110 may configure UE 120 via downlink control information (DCI), radio resource control (RRC) signaling, media access control-control element (MAC-CE), or via system information (e.g., system information block (SIB)).

[0044] As indicated above, Figure 1 This is provided merely as an example. Other examples may differ from those provided. Figure 1 The content described.

[0045] Figure 2 A block diagram of a design 200 for base station 110 and UE 120 is shown. Base station 110 and UE 120 can be Figure 1 One of the base stations and one of the UEs. Base station 110 may be equipped with T antennas 234a to 234t, and UE 120 may be equipped with R antennas 252a to 252r, wherein generally T ≥ 1 and R ≥ 1.

[0046] At base station 110, transmit processor 220 can receive data destined for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on the Channel Quality Indicator (CQI) received from each UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. Reducing the MCS decreases throughput but improves transmission reliability. Transmit processor 220 can also process system information (e.g., semi-static resource allocation information (SRPI) and control information (e.g., CQI requests, grants, upper-layer signaling, etc.) and provide overhead symbols and control symbols. Transmit processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can process its own output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted via T antennas 234a to 234t, respectively. According to the aspects described in more detail below, position coding can be used to generate synchronization signals to convey additional information.

[0047] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM, etc.) to obtain received symbols. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on these received symbols where applicable, and provide detected symbols. Receiver processor 258 can process (e.g., demodulate and decode) these detected symbols, provide the decoded data for UE 120 to data sink 260, and provide the decoded control information and system information to controller / processor 280. The channel processor can determine the Reference Received Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Received Quality (RSRQ), Channel Quality Indicator (CQI), and so on. In some respects, one or more components of the UE 120 may be included in the housing.

[0048] On the uplink, at UE 120, transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., reports including RSRP, RSSI, RSRQ, CQI, etc.). Transmit processor 264 can also generate reference symbols for one or more reference signals. Symbols from transmit processor 264 can be pre-encoded by TX MIMO processor 266 where applicable, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to base station 110. At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 254, detected by MIMO detector 236 where applicable, and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. The receiver processor 238 can provide decoded data to the data sink 239 and decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the core network 130 via the communication unit 244. The core network 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0049] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2Any other component may perform one or more techniques associated with the UE-assisted measurement gap configuration, as described in more detail elsewhere. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component (such as) may execute or direct, for example Figure 6 and 7 The operation of the process and / or other processes described herein. Memory 242 and 282 may store data and program code for base station 110 and UE 120, respectively. Scheduler 246 may schedule the UE for data transmission on downlink and / or uplink.

[0050] In some aspects, UE 120 may include means for receiving, means for transmitting, and means for suspending. In some aspects, base station 110 may include means for receiving and means for transmitting. Such means may include combinations of... Figure 2 The UE 120 or one or more components of the base station 110 described.

[0051] As indicated above, Figure 2 This is provided merely as an example. Other examples may differ from those provided. Figure 2 The content described.

[0052] In 5G deployments, 5G coverage may not be uniform. That is, some areas may have better coverage than others. Thus, there may be areas where User Equipment (UE) cannot measure 5G signals. UEs can measure 5G signals while connected (e.g., in Radio Resource Control (RRC) connectivity mode) to a Long Term Evolution (LTE) Master Node (MN). 5G signals can also be measured during measurement intervals.

[0053] Figure 3 This is timing diagram 300 illustrating an example of receiving measurement gap configuration when in connected mode. Figure 3 In the example, UE 120 (such as Figure 1 (As described) can be used with base station 110 (such as Figure 1 The described mode is in connectivity mode (e.g., RRC connectivity mode). Figure 3 Base station 110 can be an example of an LTE master node (MN).

[0054] like Figure 3As shown, at time t1, base station 110 transmits a measurement gap configuration to UE 120. The measurement gap configuration can be a master node measurement gap configuration for measuring 5G signals. The measurement gap configuration can indicate the measurement gap length (e.g., duration), such as 1.5ms, 3ms, 3.5ms, 4ms, 5.5ms, and 6ms, and the measurement gap periodicity, such as 20ms, 40ms, 80ms, and 160ms. For example, the measurement gap can repeat every 20ms and can have a duration of 1.5ms. At time t1, base station 110 can also transmit a new radio measurement configuration ( Figure 3 (Not shown in the image).

[0055] Reducing the length and / or periodicity of the measurement gap can increase LTE throughput. However, when the UE 120 enters an area with 5G coverage, reducing the length and / or periodicity of the measurement gap may delay the detection of the 5G network.

[0056] In some scenarios, UE 120 can detect the 5G network during measurement intervals and can transmit measurement reports to base station 110. Figure 3 (Not shown in the image). Base station 110 can release the measurement gap in response to receiving a measurement report.

[0057] In other scenarios, UE 120 may not detect the 5G network during the measurement gap, and base station 110 may not receive measurement reports from UE 120. In such scenarios, the behavior of base station 110 (e.g., the LTE network) is undefined. In one example, base station 110 may maintain the measurement gap. That is, base station 110 may not release the measurement gap. In this example, maintaining the measurement gap may reduce LTE throughput because data scheduling may not be performed during the measurement gap.

[0058] As another example, such as Figure 3 As shown, base station 110 starts a timer (at time t2) after transmitting the measurement gap configuration (at time t1). This timer can be referred to as the measurement gap validity timer. In this example, if UE 120 does not transmit a measurement report before the timer expires, base station 110 releases the measurement gap (at time t3). Figure 3 As shown, base station 110 transmits an RRC reconfiguration message to release the measurement gap (at time t3).

[0059] The timer duration can be blindly configured by base station 110. Therefore, the timer duration may be less than the time required for UE 120 to measure the 5G signal. Consequently, base station 110 may miss opportunities to receive measurement reports and / or add 5G network access.

[0060] It is desirable for the UE to provide auxiliary information for configuring one or more elements of the measurement gap. Aspects of this disclosure relate to UE-assisted measurement gap requests and releases. As an example, the UE may transmit measurement gap requests and / or measurement gap releases to perform measurements (e.g., neighboring cell measurements), perform multi-SIM (MSIM) decoupling, and / or save power. Measurement gap requests and / or measurement gap releases may be transmitted for purposes other than performing measurements, performing MSIM decoupling, and saving power.

[0061] In one configuration, during call setup, the UE can indicate its preferred measurement gap duration, measurement gap periodicity, and / or measurement gap effective timer duration. The base station can configure the measurement gap and / or timer as indicated by the UE in its preferences.

[0062] Figure 4 This is a timing diagram 400 illustrating an example of UE 120 providing measurement gap preferences to base station 110 according to various aspects of this disclosure. Figure 4 In the example, UE 120 (such as Figure 1 (As shown) can be used with base station 110 (such as Figure 1 (As shown) Perform call setup. Figure 4 Base station 110 can be an example of an LTE master node (MN).

[0063] exist Figure 4 In the example, at time t1, UE 120 transmits a first message to base station 110. The first message may include a preferred measurement gap configuration indicating one or more of the following: measurement gap periodicity, measurement gap duration (e.g., length), and measurement gap effective timer duration. As described, the first message may be transmitted during call setup (such as RRC setup). In one configuration, the first message includes an RRC setup request message, a call resumption request message, or a handover request message. Additionally or alternatively, the first message may be a measurement report.

[0064] like Figure 4 As shown, at time t2, base station 110 transmits a second message to UE 120. The second message may be an RRC setup message, an RRC recovery message, a handover command, or an RRC configuration message. In one configuration, the second message is transmitted in response to the first message. Alternatively, the transmission of the second message may be independent of the first message. The second message may include a measurement gap configuration, measurement gap reconfiguration, and / or measurement gap release according to a preferred measurement gap configuration.

[0065] In some implementations, UE 110 can measure or attempt to measure neighboring cells, such as 5G cells, during a measurement gap configured or reconfigured according to the measurement gap configuration received in the second message. If the UE successfully measures a neighboring cell during the configured measurement gap ( Figure 4 (not shown in the image), then UE 110 can transmit a measurement report to base station 110.

[0066] exist Figure 4 In the example, in response to transmitting the second message, base station 110 may start a timer (e.g., a measurement gap effective timer) at time t3. The duration of the measurement gap effective timer can be configured according to the preferred measurement gap configuration received in the first message (time t1).

[0067] exist Figure 4 In the example, if UE 120 does not transmit a measurement report before the measurement gap validity timer expires, base station 110 releases the measurement gap. In this example, at time t4, if no measurement report is received from UE 120 before the measurement gap validity timer expires, base station 110 transmits a third message including the release of the measurement gap. This third message may be a Radio Resource Control (RRC) reconfiguration message.

[0068] According to various aspects of this disclosure, UE 120 and / or base station 110 may transmit measurement gap configuration or measurement gap release requests via one or more messages, such as Radio Resource Control (RRC) messages, Media Access Control-Control Element (MAC-CE) messages, Downlink Control Information (DCI) messages, or Channel State Information (CSI) messages.

[0069] Figure 5 This is a timing diagram 500 illustrating examples of transmission measurement gap configuration and / or measurement gap release requests according to various aspects of this disclosure. Figure 5 In the example, UE 120 (such as Figure 1 (As described) can be used with base station 110 (such as Figure 1 (As described) is in LTE connectivity mode. Figure 5 Base station 110 can be an example of an LTE master node (MN).

[0070] At time t1, when in connected mode, the measurement gap condition is met. The measurement gap condition may include one or more conditions that trigger UE 120 to request a measurement gap from base station 110. For example, the measurement gap condition may be met when UE 120 initiates a search for neighboring NR cells using historical data. The search may be a background search. In one configuration, the search may be initiated due to a change in the battery level of UE 120.

[0071] As another example, UE 120 may request a measurement gap due to overheating or battery conditions. That is, if the battery charge is less than a battery threshold or the heat level of UE 120 is greater than a heat threshold, the measurement gap condition can be met (at time t1). Accordingly, a measurement gap can be requested to save power or reduce heat.

[0072] In some implementations, UE 120 is a multi-subscriber identity module (MSIM) UE. In this implementation, when disengagement is initiated for one of the multiple SIMs, a measurement gap condition can be satisfied. As an example, for disengagement, the UE may transmit a measurement gap configuration and / or a measurement gap release request.

[0073] In response to the satisfaction of the measurement gap condition (at time t1), UE 120 transmits a first message to base station 110 (at time t2). The first message may be a Radio Resource Control (RRC) message, a Channel State Information (CSI) message, or a Media Access Control-Control Element (MAC-CE) message. Additionally, the first message may include measurement gap configuration, measurement gap reconfiguration, selection from the measurement gap pool, and / or a measurement gap release request. The measurement gap configuration and reconfiguration included in the first message may request measurement gap duration and / or measurement gap periodicity. The measurement gap duration may be in response to Quality of Service (QoS), battery level, UE implementation, or device temperature.

[0074] In one configuration, base station 110 may be configured with a set of measurement gaps (e.g., a pool of measurement gaps), wherein each measurement gap in the set may have a different duration and / or periodicity. In this configuration, a first message may request one of the measurement gaps from the set of measurement gaps. For example, the request may be transmitted via a bit mapping that identifies the requested measurement gap.

[0075] like Figure 5 As shown, base station 110 may transmit a second message to UE 120 (at time t3). The second message may be an RRC message, a MAC-CE message, or a downlink control information (DCI) message. This second message may include measurement gap configuration, measurement gap reconfiguration, selection from the measurement gap pool, and / or measurement gap release. The second message may also request UE 120 to suspend communication with base station 110 during the configured measurement gap.

[0076] A second message can be transmitted in response to a first message. Alternatively, the second message can be transmitted independently of the transmission of the first message.

[0077] In response to a measurement gap configuration or reconfiguration received in the second message, the UE may suspend communication with the first network (e.g., an LTE network) during the measurement gap. Figure 5(Not shown in the diagram). In one configuration, the UE can be disconnected during a measurement interval. Disconnection can be performed on one of multiple SIMs.

[0078] To extend the length of the measurement gap, at time t4, UE 120 may delay the transmission of reconfiguration completion messages (such as RRC reconfiguration completion messages). As described, the length of the measurement gap (e.g., the measurement gap duration) may be based on Quality of Service (QoS), battery level, UE implementation, or device temperature. For example, when the battery level is below a battery threshold, the UE may delay the transmission of the RRC reconfiguration completion message.

[0079] like Figure 5 As shown, at time t5, UE 120 transmits a third message to base station 110. The third message may request the release of the measurement gap. The third message may be an RRC message (e.g., an RRC reconfiguration complete message), a MAC-CE message, or a CSI message.

[0080] Additionally, base station 110 may transmit a fourth message (at time t6). This fourth message may include measurement gap release. In one implementation, the fourth message is an RRC message (e.g., an RRC reconfiguration message), a MAC-CE message, or a DCI message. The fourth message may be transmitted in response to the third message. Alternatively, the fourth message may be transmitted independently of the transmission of the third message.

[0081] This disclosure includes methods for providing UE-assisted information for configuring and / or releasing measurement gaps. The UE-assisted information can be provided in response to UE battery status, Quality of Service (QoS) specifications, UE implementation, and / or other factors or conditions.

[0082] Various aspects of this disclosure can improve the speed of configuring and / or releasing measurement gaps. By improving the speed of configuring and / or releasing measurement gaps, various aspects of this disclosure can improve network throughput, such as LTE master node throughput and / or Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN) NR-Dual Connectivity (ENDC) throughput. Although non-autonomous deployments with multi-point coverage are mentioned, this disclosure also envisions autonomous deployments. For example, a UE can switch from frequency range 1 (FR1) to frequency range 2 (FR2), or vice versa.

[0083] As indicated above, Figures 3-5 This is provided as an example. Other examples may differ from the one provided. Figures 3-5 The example described.

[0084] Figure 6 This is a flowchart illustrating, for example, an example process 600 performed by a UE according to various aspects of this disclosure. The UE can be, for example,... Figure 1 The UE 120 described herein. Example procedure 600 is an example of user equipment (UE) measurement gap request and release for power saving and multi-subscriber identity module (MSIM) measurements.

[0085] like Figure 6 As shown, in some aspects, process 600 may include transmitting a first message to the first network, including a first measurement gap configuration, measurement gap reconfiguration, selection from a measurement gap pool, or a measurement gap release request (block 602). For example, the UE (e.g., using antenna 252, DEMOD / MOD 254, TX MIMO processor 266, transmit processor 264, controller / processor 280, and / or memory 282) may transmit the first message, such as a measurement gap release request, to the first network. In some aspects, the first network may be the same radio access technology (RAT) (e.g., self-deployed) or a different RAT (non-self-deployed).

[0086] In some aspects, process 600 may include receiving a second message from a first network. The second message may configure, reconfigure, or release a measurement gap; and suspend data communication from the UE during the configured measurement gap (block 604). For example, the UE (e.g., using antenna 252, DEMOD / MOD 254, MIMO detector 256, receive processor 258, controller / processor 280, memory 282) may receive the second message from the first network.

[0087] like Figure 6 As shown, in some aspects, process 600 may include suspending communication with the first network during a configured measurement gap (block 606). For example, the UE (e.g., using antenna 252, DEMOD / MOD 254, MIMO detector 256, TX MIMO processor 266, receive processor 258, transmit processor 264, controller / processor 280, memory 282, etc.) may suspend communication with the first network during a configured measurement gap. In some aspects, communication may be suspended to save power, perform multi-subscriber identity module (MSIM) disconnection, or measure neighboring cells.

[0088] Figure 7 This is a flowchart illustrating, for example, an example process 700 performed by a base station according to various aspects of this disclosure. The base station can be, for example, as... Figure 1 The base station 110 is described. Example process 700 is an example of measurement gap request and measurement gap release for power saving and multi-subscriber identity module (MSIM) measurements.

[0089] like Figure 7As shown, in some aspects, process 700 may include transmitting a first message including a measurement gap configuration to a user equipment (UE) (block 702). For example, a base station (e.g., using antenna 234, MOD / DEMOD 232, TX MIMO processor 230, transmit processor 220, controller / processor 240, and / or memory 242) may transmit the first message including the measurement gap configuration to the UE. In some aspects, the first message may include a table of measurement gap configurations and associated measurement gap mode indexes.

[0090] In some aspects, process 700 may include receiving a second message from the UE (block 704). For example, a base station (e.g., using antenna 234, MOD / DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, and / or memory 242) may receive the second message from the UE.

[0091] like Figure 7 As shown, in some aspects, process 700 may include transmitting a third message to the UE, including one or more of measurement gap establishment, measurement gap timer duration, or measurement gap release (block 706). For example, a base station (e.g., using antenna 234, MOD / DEMOD 232, TX MIMO processor 230, transmit processor 220, controller / processor 240, and / or memory 242) may transmit the third message to the UE. In some aspects, the third message may include a downlink control information (DCI) message or a media access control-control element (MAC-CE) message. Additionally, in some aspects, the third message may indicate a selected measurement gap mode index.
