[0042] Some aspects of the present disclosure relate to apparatus and methods for implementing techniques for performing intelligent power saving operations of wireless communication systems. The implemented techniques may be applicable to many wireless systems, for example, wireless communication systems based on one or more 3GPP standards, such as described in, for example, 3GPP TS 38.331 3GPP 38.133, 3GPP 38.304, 3GPP 36.133, 3GPP 36.331, or others.

[0043] The wireless communication system may include a fifth generation (5G) system, a new radio (NR) system, a long term evolution (LTE) system, a combination thereof, or some other wireless system. The wireless communication system (e.g., a UE) may perform a cell search and reselection procedure based on various parameters. The cell reselection procedure may ensure that the UE can camp on or connect to the best cell in terms of radio conditions (e.g., in terms of path loss or RSRP metrics). The UE may perform intra-frequency cell reselection or inter-frequency cell reselection in different frequency bands. The UE may perform some measurements, such as inter-frequency or inter-radio access technology (RAT) measurements, to support the cell reselection procedure, which may affect the power consumption of the UE.

[0044] In some aspects, power consumption may be an issue for a UE, and the availability of power may vary depending on the UE. For example, the UE may be a low-power wireless device and / or may be more power sensitive than another type of UE. In another example, it may be desirable to increase the battery life of the UE. In this regard, current methods for cell reselection may not produce optimal results for the UE to increase battery life.

[0045] Certain aspects of the present disclosure provide mechanisms for intelligent power save operation of wireless communication systems.

[0046] Figure 1 An example system implementing mechanisms for performing intelligent power save operations at a wireless communication system in accordance with some aspects of the present disclosure is illustrated.Example system 100 is provided for illustration purposes only and not to limit the disclosed aspects.

[0047] The wireless network 100 includes, but is not limited to, network nodes (e.g., base stations, such as evolved Node B [eNB], next generation Node B [gNB]) 101 and 103 and electronic devices (e.g., UE) 105. There may be other network entities not shown, such as network controllers, relay stations. The electronic device 105 (hereinafter referred to as UE 105) may include an electronic device configured to operate based on a variety of wireless communication technologies. These technologies may include, but are not limited to, technologies based on the third generation partnership project (3GPP) standards. For example, the UE 105 may include an electronic device configured to operate based on one or more 3GPP standards, such as described in, for example, 3GPP TS 38.331 3GPP 38.133, 3GPP 38.304, 3GPP 36.133, 3GPP 36.331, or others. The UE 105 may include, but is not limited to: a wireless communication device, a smart phone, a laptop computer, a desktop computer, a tablet computer, a personal assistant, a monitor, a television, a wearable device, an Internet of Things (IoT), a vehicle communication device, etc. The network nodes 101 and 103 (referred to herein as base stations) and the associated cells 102 and 104 may include nodes configured to operate based on a variety of wireless communication technologies, such as, but not limited to, technologies based on 3GPP standards. For example, the base stations 101 and 103 may include nodes configured to operate based on one or more 3GPP standards, such as described in, for example, 3GPP TS 38.331 3GPP 38.133, 3GPP 38.304, 3GPP 36.133, 3GPP 36.331, or others.

[0048] According to some aspects, UE 105 is configured to implement mechanisms for performing intelligent power saving operations as described herein.

[0049] In some aspects, the UE 105 may be configured to determine whether the mobile state associated with the UE 105 is in a predefined condition. The UE 105 may be configured to determine the mobile state by using one or more location and / or motion sensors (e.g., GPS, accelerometer, gyroscope sensor, etc.) of the UE 105's movement information (e.g., speed, acceleration, etc.) and / or using one or more location determinations (e.g., location fingerprinting) relative to signal characteristics of one or more base stations and / or access points. In one example, the UE 105 may be configured to determine that the mobile state is stationary or substantially stationary within a predefined time period. In another example, the UE 105 may be configured to determine that the mobile state indicates that the UE is moving at a speed lower than a predetermined speed, a distance determined at a predetermined distance, or a time period determined at a predetermined distance. For example, the UE 105 may be configured to determine that the mobile state indicates that the UE is moving at a speed lower than a pedestrian or vehicle speed, a short distance, or a short time period.

[0050] In some aspects, the UE 105 may be configured to determine operational information associated with the UE 105, including, but not limited to, location information, movement information, power level information, or application information. In some aspects, the UE 105 may be configured to determine location information through movement information from one or more location and / or motion sensors (e.g., GPS, accelerometer, gyroscope sensor, etc.) and / or using one or more location determinations (e.g., location fingerprinting) of signal characteristics relative to one or more base stations and / or access points. For example, the UE 105 may be configured to determine a fingerprinting location associated with the UE 105 as, for example, a home or office associated with a user of the UE 105 based on the location information. The UE 105 may be configured to determine a high priority search in cell selection and reselection at the fingerprinting location. The UE 105 may be configured to determine that the movement associated with the UE 105 is within predefined limits based on the movement information.

[0051] In some aspects, the UE 105 may be configured to determine power level information to determine a power mode and / or power level of a battery associated with the UE 105. In some aspects, the UE 105 may be configured to determine background processing information. For example, the UE 105 may be configured to determine background synchronization processes for applications (such as email or calendar applications) and / or background public land mobile network (PLMN) searches.

[0052] In some aspects, the UE 105 may be configured to perform one or more signal measurements to measure the serving cell and neighbor cell signal strength or signal quality matrix, i.e., reference signal received power (RSRP), reference signal received quality (RSRQ). In some aspects, the UE 105 may be configured to measure the serving cell power level by, for example, measuring RSRP. In some aspects, when camping on a cell (e.g., cell 102), the UE 105 may be configured to periodically search for a better cell according to a cell reselection criterion. If a better cell is found, that cell (e.g., neighbor cell 104) may be selected. A change in a cell may mean a change in RAT. In some aspects, cell reselection may be performed to a cell on an NR frequency or an inter-RAT frequency with a higher priority than the serving frequency. According to some aspects, the UE 105 may be configured to perform measurements such as inter-frequency and / or inter-RAT measurements to support cell selection and reselection procedures. For example, when in idle mode, the UE 105 may be configured to measure the signal strength and / or quality (e.g., RSRP, RSRQ) of the serving cell at least every discontinuous reception (DRX) cycle. The UE 105 may be configured to select a set of measurement entities based on a configured selection rule. In some aspects, the UE 105 may be configured to perform inter-frequency measurements based on various conditions (e.g., every DRX cycle, after reselection of another cell, etc.).

[0053] In some aspects, UE 105 may be configured to determine operational information associated with a cell (e.g., serving cell 101), including but not limited to power level information or system information. UE 105 may be configured to determine whether the power level of a serving cell (e.g., cell 101) fluctuates within predefined limits by performing one or more signal measurements. In some aspects, UE 105 may be configured to determine one or more states based on system information associated with a serving cell, such as a cell being disabled and / or a dedicated priority change or de-prioritization of a serving cell. However, aspects of the present disclosure are not limited to these examples. In some aspects, UE 105 may be configured to determine one or more states such as cell congestion.

[0054] In some aspects, as described in 3GPP 38.304, the absolute priority of different NR frequencies or inter-RAT frequencies may be provided to the UE 105 in system information, in the RRCRelease message, or by inheritance from another RAT at inter-RAT cell selection (reselection). If the UE 105 is in the camped on any cell state, the UE 105 should only apply the priority provided by the system information from the current cell, and unless otherwise specified, the UE 105 retains the priority provided by the dedicated signaling and deprioritisationReq received in the RRCRelease. When the UE 105 is in the normal camped state and the UE 105 is only provided with a dedicated priority different from the current frequency, the UE 105 should consider the current frequency to be the lowest priority frequency (i.e., lower than any network configured value in the network configured value). The UE 105 should perform cell reselection evaluation only for NR frequencies and inter-RAT frequencies that are given in the system information and for which the UE 105 has a priority provided.

In some examples, the operating system 252 maintains one or more network protocol stacks (e.g., an Internet protocol stack, a cellular protocol stack, etc.) that may include multiple logical layers. At the corresponding layer of the protocol stack, the operating system 252 includes control mechanisms and data structures to perform functions associated with the layer.

Applications in applications 254 may include applications such as, but not limited to, radio streaming, video streaming, remote control, email, calendar, and / or other user applications.

[0058] The system 200 may also include a communication infrastructure 240. The communication infrastructure 240 provides, for example, communication between the processor 210, one or more transceivers 220a to 220n, and the memory 250. In some specific implementations, the communication infrastructure 240 may be a bus. In various embodiments, the processor 210, together with instructions stored in the memory 250, performs operations that enable the system 200 to implement the mechanisms for performing intelligent power saving operations as described herein. In various embodiments, the processor 210 is "hardwired" or "hardcoded" to implement the mechanisms for performing intelligent power saving operations as described herein.

Antenna 260 may include one or more antennas that may be the same or different types. One or more transceivers 220a to 220n allow system 200 to communicate with other devices that may be wired and / or wireless.

The cellular network may include, but is not limited to, a 3G / 4G / 5G network, such as Universal Mobile Telecommunications System (UMTS), Long Term Evolution (LTE), 5G, etc. For example, one or more transceivers 220a to 220n may be configured to operate in accordance with one or more of the 3GPP standards, such as described in, for example, 3GPP TS 38.331 3GPP38.133, 3GPP 38.304, 3GPP 36.133, 3GPP 36.331.

[0063] According to some aspects, processor 210 alone or in combination with computer instructions stored in memory 250 and / or one or more transceivers 220a to 220n implements operations for performing intelligent power save operations at a wireless communication system, as described herein.

[0064] Figure 3 An example method for a system (e.g., a UE) for performing intelligent power saving operations according to some aspects of the present disclosure is illustrated. The method 300 may be applicable to a wireless system, for example, a wireless communication system based on one or more 3GPP standards, such as described in, for example, 3GPP TS 38.331 3GPP 38.133, 3GPP 38.304, 3GPP 36.133, 3GPP 36.331, or others. For convenience and not limitation, Figure 3 You can refer to Figure 1 to Figure 2 Method 300 may represent an electronic device (e.g., Figure 1UE 105) implements the operation of a mechanism for performing intelligent power saving operation at a wireless communication system. The method 300 may also be performed by Figure 2 System 200 and / or Figure 5 However, the method 300 is not limited to the specific aspects depicted in those figures, and other systems may be used to perform the method, as will be appreciated by those skilled in the art. It should be understood that not all operations may be required, and these operations may not be performed in order. Figure 3 The same order as shown is followed.

[0065] At 302, it is determined whether a mobility state associated with the UE satisfies one or more mobility conditions. In some aspects, the UE may be in an RRC_CONNECTED state, an RRC_IDLE state, or an RRC_Inactive state. In some aspects, the mobility state may include a mobility state of being at least substantially stationary. In some aspects, the mobility state may include a mobility state of moving below a predetermined speed, a predetermined distance, or a predetermined time period.

[0066] In some aspects, the mobile state may be determined by using movement information (e.g., speed, acceleration, etc.) of the UE using one or more location and / or motion sensors (e.g., GPS, accelerometer, gyroscope sensor, etc.). In one example, the mobile state may be determined as being stationary for a specific period of time. The mobile state may be determined as moving at a speed lower than a predetermined speed, a distance determined in advance, or a time period determined in advance. For example, the mobile state may be determined as moving at a speed lower than a pedestrian or vehicle speed, a short distance, or a short time period.

[0067] In some aspects, one or more movement conditions may include a movement state of at least substantially stationary, moving less than a predetermined speed, a predetermined distance, and / or a predetermined period of time.

The operational information includes location information, power level information, or background processing information.

[0069] In some aspects, location information may be determined via location fingerprinting. Location fingerprinting may be associated with one or more location determinations using signal characteristics relative to one or more base stations and / or access points.

[0070] The location information may be associated with a fingerprinted location associated with a user of the UE based on user information within an application, such as a "maps" application. The fingerprinted location may include a location indicating home, office, and / or one or more other significant locations associated with the user.

[0071] In some aspects, operational information associated with the UE may include movement information. In some aspects, the movement information may be determined by a motion sensor.

[0072] In some aspects, the mobility information may include, for example, that the UE's movement is within allowed limits, such as moving below a predetermined speed, a predetermined distance, or a predetermined time period.

[0073] At 306, signal measurements associated with neighbor cells are stopped based at least on the operational information and one or more operational conditions being satisfied. In some aspects, signal measurements associated with neighbor cells may be associated with a cell reselection procedure, such as including 3GPP TS 38.331, 3GPP 38.133, 3GPP 38.304, 3GPP 36.133, 3GPP 36.331, or others. In some aspects, signal measurements may include inter-frequency measurements or inter-radio access technology (inter-RAT) measurements.

[0075] In some aspects, when the location associated with the UE is one of a plurality of predetermined locations, signal measurements associated with neighbor cells may be stopped. In some aspects, when the power level of the UE is below a predetermined threshold, signal measurements associated with neighbor cells may be stopped.

[0076] In some aspects, when the location associated with the UE is one of a plurality of predetermined locations and a search for a higher priority frequency is determined, signal measurements associated with the neighbor cell may be stopped.

[0077] In some aspects, when background synchronization of an application or background PLMN search is determined, signal measurements associated with neighbor cells may be stopped.

[0078] In some aspects, when the mobility associated with the UE is above a predetermined threshold (including, for example, movement for a hysteresis period or a hysteresis distance), the signal measurements associated with the neighbor cells may be resumed. In some aspects, when it is determined that the cell is congested, the signal measurements associated with the neighbor cells may be resumed. In some aspects, when it is determined that the cell is barred, the signal measurements associated with the neighbor cells may be resumed. In some aspects, when it is determined that the dedicated priority of the cell changes or is de-prioritized, the signal measurements associated with the neighbor cells may be resumed.

[0079] In some aspects, when the power of the serving cell degrades below an acceptable threshold, the signal measurements associated with the neighbor cells may be resumed. In some aspects, when the priority information in the received system information changes, the signal measurements associated with the neighbor cells may be resumed. In some aspects, when the UE is paging a voice call, the signal measurements associated with the neighbor cells may be resumed.

[0080] Figure 4 An example method for a system (e.g., a UE) for performing intelligent power saving operations according to some aspects of the present disclosure is illustrated. The method 400 may be applicable to a wireless system, for example, a wireless communication system based on one or more 3GPP standards, such as described in, for example, 3GPP TS 38.331 3GPP 38.133, 3GPP 38.304, 3GPP 36.133, 3GPP 36.331, or others. For convenience and not limitation, reference may be made to Figures 1 to 3 Description of the elements Figure 4 Method 400 may represent an electronic device (eg, Figure 1 UE 105) implements the operation of a mechanism for performing intelligent power saving operation at a wireless communication system. The method 400 may also be performed by Figure 2 System 200 and / or Figure 5 However, as will be appreciated by those skilled in the art, method 400 is not limited to the specific aspects depicted in those figures, and other systems may be used to perform the method. It should be understood that not all operations may be required, and these operations may not be performed in the same manner as described above. Figure 4 The same sequence as shown is performed.

[0081] At 402, it is determined that the UE (e.g., UE 105) is powered on. At 412, it is determined that the UE 105 is in the RRC_Idle state. At 422, when the UE 105 is in the RRC_Idle state, it is determined that the UE 105 is in a stationary state. Alternatively, at 424, when the UE 105 is in the RRC_Idle state, it is determined that the UE 105 is in a mobile state, such as the mobile state satisfies one or more mobile conditions.

[0082] Alternatively, at 414, it is determined that the UE 105 is in the RRC_CONNECTED state or the RRC_Inactive state. At 426, when the UE 105 is in the RRC_CONNECTED state or the RRC_Inactive state, it is determined that the UE 105 is in the stationary state. Alternatively, at 428, when the UE 105 is in the RRC_CONNECTED state or the RRC_Inactive state (such as, the mobile state satisfies one or more mobile conditions), it is determined that the UE 105 is in the mobile state.

[0083] In some aspects, UE 105 may be configured to determine whether the mobile state meets one or more mobile conditions. UE 105 may be configured to determine the mobile state by checking the mobile information (e.g., speed, acceleration, etc.) of UE 105 using one or more position and / or motion sensors (e.g., GPS, accelerometer, gyroscope sensor, etc.). UE 105 may be configured to determine that the mobile state meets one or more mobile conditions, including: moving below a predetermined speed, moving below a predetermined distance, or being stationary for a predetermined time period. In one example, UE 105 may be configured to determine that UE 105 remains stationary for a specific time period. In another example, UE 105 may be configured to determine that the mobile state is moving below the speed of pedestrians or vehicles, a short distance, or a short time period.

[0084] At 430, the UE 105 is configured to determine whether the UE 105 is in a fingerprinting location (e.g., home or office) in which the movement is within the allowed limits. The UE 105 may be configured to detect and / or store one or more important locations associated with the user of the UE 105 based on user information within an application (such as a map application). For example, the UE 105 may be configured to detect and store one or more important known locations, such as "home" and / or "work". In some aspects, when a user registers in an important location in the important locations, the user may stay there for a period of time. The UE 105 may be configured to determine the fingerprinting location based on one or more location determinations (e.g., location fingerprinting) using signal characteristics relative to one or more base stations and / or access points. The UE 105 may be configured to determine that the movement of the UE 105 is within the allowed limits, such as moving below a predetermined speed, within a predetermined distance, or within a predetermined time period. In one example, the UE 105 may be configured to determine that the UE 105 remains stationary for a specific period of time. In another example, the UE 105 may be configured to determine that the movement state is movement below pedestrian or vehicle speed, for a short distance, or for a short period of time.

[0085] If it is determined that the UE 105 is in a fingerprinting location (eg, home or office) where motion is within allowed limits, the method 400 proceeds to 440. At 440, the UE 105 is configured to stop one or more inter-frequency and inter-RAT neighbor measurements.

[0086] In some aspects, the UE 105 may be configured to fingerprint one or more cells at the fingerprinting location and detect whether the UE 105 experiences any mobility at the fingerprinting location. In some aspects, when the UE experiences mobility at the fingerprinting location, a deployment frequency associated with the UE at the fingerprinting location may be determined. The UE 105 may be configured to form a table of deployment frequencies per location. In some aspects, if the UE is non-stationary at the fingerprinting location, the UE 105 may be configured to enable signal measurements of only the deployment frequencies.

[0087] If it is determined that the UE 105 is not in a fingerprinting location (eg, home or office) where motion is within allowed limits, the method 400 proceeds to 452 , 454 , 456 , and 458 .

[0088] At 452, the UE 105 is configured to determine whether the motion of the UE 105 exceeds a threshold, such as movement exceeding a predetermined speed threshold, a predetermined distance threshold, or a predetermined time period threshold (e.g., a hysteresis period or hysteresis distance). If it is determined at 452 that the motion of the UE 105 exceeds the threshold, then at 460, the UE 105 is configured to restart or continue one or more inter-frequency and inter-RAT neighbor measurements. If it is determined at 452 that the motion of the UE 105 does not exceed the threshold, the method 400 proceeds to 440.

[0089] At 454, the UE 105 is configured to determine whether the cell (e.g., the serving cell) is congested. If it is determined that the cell (e.g., the serving cell) is congested, then at 460, the UE 105 is configured to restart or continue one or more inter-frequency and inter-RAT neighbor measurements. In some aspects, the UE 105 may be configured to measure and determine that the serving cell signal strength or signal quality matrix (i.e., reference signal received power (RSRP), reference signal received quality (RSRQ)) is below a threshold. If it is determined that the cell (e.g., the serving cell) is not congested, the method 400 proceeds to 440.

[0090] At 456, the UE 105 is configured to determine whether the cell (e.g., the serving cell) is barred. If it is determined that the cell (e.g., the serving cell) is barred, then at 460, the UE 105 is configured to restart or continue one or more inter-frequency and inter-RAT neighbor measurements. In some aspects, the UE 105 may be configured to obtain the cell barring information from system information broadcast by the serving cell. If it is determined that the cell (e.g., the serving cell) is not barred, the method 400 proceeds to 440.

[0091] At 458, the UE 105 is configured to determine whether there is a dedicated priority change or de-prioritization of the serving cell. If there is a dedicated priority change or de-prioritization of the serving cell, the UE 105 is configured to restart or continue one or more inter-frequency and inter-RAT neighbor measurements at 460. In some aspects, the UE 105 may be configured to determine the priority information change through one or more system information (e.g., SIBx) changes. If there is no dedicated priority change or de-prioritization of the serving cell, the method 400 proceeds to 440.

[0092] As described in 3GPP TS 38.304, if the UE is in the Camped on any cell state, the UE shall apply only the priority provided by the system information from the current cell and, unless otherwise specified, the UE retains the priority provided by the dedicated signaling received in RRCRelease and deprioritisationReq. When a UE in the Normal Camped state has only a dedicated priority different from the current frequency, the UE shall consider the current frequency to be the lowest priority frequency (i.e., lower than any network configured value in the network configured value).

[0093] At 432, the UE 105 is configured to determine whether the signal power level of the serving cell fluctuates within a predefined limit. In some aspects, the UE 105 may be configured to measure and determine that the serving cell signal strength or signal quality matrix (i.e., reference signal received power (RSRP), reference signal received quality (RSRQ)) is below a threshold. In some aspects, the limit may be a predetermined threshold. In some aspects, the limit may be a predetermined threshold in a plurality of predetermined thresholds corresponding to a plurality of power ranges, respectively.

[0094] If the power level of the serving cell fluctuates within certain limits, the method 400 proceeds to 440. At 440, the UE 105 is configured to stop one or more inter-frequency and inter-RAT neighbor measurements.

[0095] If the power level of the serving cell does not fluctuate within certain limits, method 400 proceeds to 452 , 454 , 456 , and 458 .

[0096] At 434, the UE 105 is configured to determine whether the UE 105 is in a low power mode or whether the UE 105 is operating on a low battery.

[0097] If it is determined that the UE 105 is in a low power mode or the UE 105 is operating on a low battery, the method 400 proceeds to 440. At 440, the UE 105 is configured to stop one or more inter-frequency and inter-RAT neighbor measurements.

[0098] If it is determined that the UE 105 is not in a low power mode or the UE 105 is not operating on a low battery, the method 400 proceeds to 452 , 454 , 456 , and 458 .

[0099] At 436, the UE 105 is configured to determine whether there is a high priority search (e.g., a search for a higher priority frequency) at the fingerprinting location. In some aspects, the UE 105 may be configured to determine a high priority search based on cell selection and / or reselection parameters being broadcast in system information and read from a serving cell. For example, as described in 3GPP TS 38.304, the absolute priority of different NR frequencies or inter-RAT frequencies may be provided to the UE in system information, in an RRC Release message, or by inheriting from another RAT at the time of inter-RAT cell selection (reselection). In the case of system information, NR frequencies or inter-RAT frequencies may be listed without providing a priority (i.e., there is no field cellReselectionPriority for the frequency). If any field with cellReselectionPriority is provided in dedicated signaling, the UE shall ignore any field with cellReselectionPriority provided in the system information and any slice reselection information. If slice reselection information is provided in dedicated signaling, the UE shall ignore the slice reselection information provided in the system information.

[0100] If there is a high priority search at the fingerprinting location, the method 400 proceeds to 440. At 440, the UE 105 is configured to stop one or more inter-frequency and inter-RAT neighbor measurements.

[0101] If there is no high priority search at the fingerprinting location, method 400 proceeds to 452 , 454 , 456 , and 458 .

[0102] At 438, UE 105 is configured to determine if there is one of background synchronization of an email application, a calendar application, or a PLMN search, or any other application. In some aspects, a background synchronization application programming interface (API) may allow authorized web applications (e.g., email applications, calendar applications) to be independent of having a stable Internet connection and to postpone network-related operations until a connection is available. In some aspects, UE 105 may perform background PLMN searches for a variety of reasons (e.g., to find a high priority public land mobile network (PLMN) during roaming). If UE 105 is stationary, a new PLMN may not be found. UE 105 may allow a maximum of one background PLMN search. Alternatively, UE 105 may reduce the periodicity of PLMN searches (e.g., skip every other search).

[0103] If there is background synchronization of one of the email application, calendar application, or PLMN search, or any other application, the method 400 proceeds to 440. At 440, the UE 105 is configured to stop one or more inter-frequency and inter-RAT neighbor measurements.

[0104] If there is no background synchronization of the email application, calendar application, or PLMN search, or any other application, the method 400 proceeds to 452 , 454 , 456 , and 458 .
