Description

Radio resource management (RRM) measurement method and device, communication equipment, and storage medium Technical Field

[0001] The present disclosure relates to the field of wireless communication technology but is not limited to the field of wireless communication technology, and in particular to a radio resource management (RRM) measurement method and apparatus, a communication device, and a storage medium. Background Art

[0002] To balance low power consumption with services that have certain latency requirements, the terminal, also known as user equipment (UE), introduces the extended discontinuous reception (eDRX) mechanism. After the terminal enters the eDRX mechanism, it will wake up and sleep within the eDRX cycle.

[0003] If the eDRX cycle is long enough, each eDRX cycle has a paging time window (PTW). During the PTW, the terminal wakes up and goes to sleep according to the discontinuous reception (DRX) cycle. When awake, it monitors the paging channel to receive downlink data. The terminal remains in sleep mode during the rest of the time. If the eDRX cycle is short, the PTW is not configured, and the network device assumes that the terminal is not in sleep mode, meaning that the terminal is always reachable.

[0004] Summary of the Invention

[0005] Embodiments of the present disclosure provide an RRM measurement method and apparatus, a communication device, and a storage medium.

[0006] A first aspect of the present disclosure provides a radio resource management (RRM) measurement method, performed by a UE, including:

[0007] In response to the target eDRX cycle being greater than or equal to a preset value, performing RRM measurement within the target paging time window PTW. A second aspect of the embodiment of the present disclosure provides a radio resource management RRM measurement device, wherein the device includes:

[0008] The execution module is configured to perform RRM measurement within a target paging time window PTW in response to a target eDRX cycle being greater than or equal to a preset value.

[0009] A third aspect of an embodiment of the present disclosure provides a communication device, including a processor, a transceiver, a memory, and an executable program stored in the memory and capable of being run by the processor, wherein when the processor runs the executable program, it executes the RRM measurement method of any technical solution of the first aspect.

[0010] A fourth aspect of an embodiment of the present disclosure provides a computer storage medium storing an executable program; after the executable program is executed by a processor, the RRM measurement method of any technical solution of the first aspect can be implemented.

[0011] The technical solution provided by the embodiment of the present disclosure first limits the RRM measurements performed in the entire time domain to those performed within the target PTW, thereby reducing the RRM measurements in at least part of the time period, thereby saving the power consumption of the UE caused by the RRM measurements.

[0012] Secondly, when the UE is periodically awakened and asleep according to the target eDRX cycle, since the duration of the target eDRX cycle is relatively long, it will switch between the awake state and the asleep state according to the DRX cycle within the PTW corresponding to the executed target eDRX cycle, and will not wake up during the target eDRX cycle outside the PTW. If the RRM measurement is set outside the target PTW, the UE will need to exit the asleep state due to the RRM measurement in the time domain outside the target PTW, which may make the purpose of saving power by the eDRX mechanism unattainable or the effect less than ideal. Therefore, in the embodiment of the present disclosure, the RRM measurement is set within the PTW, that is, the UE needs to perform the RRM measurement within the target PTW that needs to be awakened based on the eDRX mechanism, thereby saving the UE's power consumption and ensuring the execution effect of the eDRX mechanism.

Depending on the context, the words used herein may be interpreted as when, when, or in response to a determination.

[0028] Please refer to Figure 1A, which shows a schematic diagram of the structure of a wireless communication system provided by an embodiment of the present disclosure. As shown in Figure 1A, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: a plurality of UEs 11 and a plurality of access devices 12. In some embodiments, the communication system may also include: one or more core network devices, which are not shown in Figure 1A. The core network devices include but are not limited to an Access Management Function (AMF), a User Plane Function (UPF), a Session Management Function (SMF), and a Policy Control Function (PCF).

[0029] UE 11 may refer to a device that provides voice and / or data connectivity to a user. UE 11 may communicate with one or more core networks via a Radio Access Network (RAN). UE 11 may be an IoT UE, such as a sensor device, a mobile phone (or cellular phone), and a computer with an IoT UE. For example, it may be a fixed, portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted device. For example, a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or user equipment (UE). Alternatively, UE 11 may be a device of an unmanned aerial vehicle. Alternatively, UE 11 may be a vehicle-mounted device, such as a driving computer with wireless communication capabilities, or a wireless communication device connected to an external driving computer. Alternatively, the UE 11 may also be a roadside device, for example, a street lamp, a traffic light, or other roadside device with a wireless communication function.

[0030] The access device 12 may be a network-side device in a wireless communication system. The wireless communication system may be a fourth generation mobile communication technology (4G) system, also known as a long term evolution (LTE) system; or, the wireless communication system may be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be a next generation system of the 5G system. The access network in the 5G system may be referred to as NG-RAN (New Generation-Radio Access Network). Alternatively, an MTC system.

[0031] Among them, the access device 12 can be an evolved access device (eNB) adopted in a 4G system. Alternatively, the access device 12 can also be an access device (gNB) that adopts a centralized distributed architecture in a 5G system. When the access device 12 adopts a centralized distributed architecture, it usually includes a centralized unit (CU) and at least two distributed units (DU). The centralized unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link layer control protocol (RLC) layer, and a media access control (MAC) layer; the distributed unit is provided with a physical (PHY) layer protocol stack. The embodiment of the present disclosure does not limit the specific implementation method of the access device 12.

[0032] A wireless connection can be established between the access device 12 and the UE 11 via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; or, the wireless air interface can also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

[0033] In related technologies, the eDRX parameters of a terminal in idle state are negotiated between the terminal and the core network through NAS messages, and are completely transparent to access devices such as base stations.

[0034] In New Radio (NR), the inactive state is introduced. At this time, the UE not only needs to receive core network paging, but also needs to receive RAN paging. In the case of reduced terminal capability (Redcap), eDRX is also introduced for the inactive state, and the eDRX parameters of the inactive state are configured by the RAN, and the eDRX cycle of the inactive state and the eDRX cycle of the idle state may be different. For example, the eDRX cycle of the inactive state is shorter than the eDRX cycle of the idle state. And the PTW length for the inactive state is also configured by the RAN. In one example, the starting point of the PTW of the inactive state and the PTW of the idle state configured by the RAN is the same, but the length can be different.

[0035] As shown in FIG1B , an eDRX cycle includes a PTW. For example, one eDRX cycle includes one PTW. A PTW includes one or more DRX cycles. The duration of a DRX cycle is shorter than the duration of an eDRX cycle.

[0036] Exemplarily, when the eDRX cycle is greater than 10.24s, the PTW of the eDRX cycle includes multiple DRXs.

[0037] Before the terminal enters the eDRX mechanism, the terminal will perform relevant signaling interactions with the network side.

[0038] For example, as shown in FIG1C , the terminal performs relevant signaling interaction with the network side, which may include:

[0039] S001: The access device sends a System Information Block (SIB) to the UE. The SIB includes an indication that the eDRX mechanism is enabled, a default DRX cycle, and a hyperframe number (SFN). After the UE receives the SIB, if the SIB includes an indication that the UE enables the eDRX mechanism, the UE determines the superframe in which to start executing the eDRX mechanism based on the superframe number. When executing the eDRX mechanism, the UE may monitor CN paging according to the default DRX cycle based on the agreement negotiated between the UE and the access device. The access device may be any of the types of access devices shown in FIG1A.

[0040] In some cases, the SIB may also include a default DRX cycle, which may also be referred to as a default paging cycle.

[0041] S002: The UE and the core network (CN) negotiate an idle state eDRX configuration, which may include idle state eDRX parameters. Specifically, the UE may send UE-specific DRX parameters (UE-specific DRX) and / or preferred DRX parameters (preferable eDRX) when sending an attach request or a tracking area update (TAU) request to the MME.

[0042] After receiving the attach request or TAU request, the CN sends an eDRX configuration to the UE. The eDRX configuration carries one or more of the eDRX parameters mentioned above. The eDRX parameters include one or more of the following: the eDRX cycle and / or the time domain start position and window length of the PTW.

[0043] S003: After completing the idle state eDRX configuration and the terminal enters the eDRX mechanism, the CN may send NG paging signaling and CN assistance information for the RRC inactive state to the access network. This NG paging signaling and CN assistance information for the RRC inactive state may include: eDRX configuration and / or DRX configuration. The DRX configuration may include the DRX cycle configured by the CN. The CN performs paging according to the eDRX configuration; after receiving the core network (CN) paging signaling issued by the MME, the access device forwards the CN paging signaling to the UE.

[0044] The eDRX parameters for the idle state are transparently transmitted to the UE via the access device. For example, a core network device such as the Mobile Management Entity (MME) or AMF of the CN sends the eDRX parameters for the eDRX mechanism to the UE via the access device. In some embodiments, the MME can be replaced by a functional network element of the CN, such as the AMF. The eDRX parameters for the idle state are negotiated between the UE and the core network via NAS messages and are completely transparent to the access device.

[0045] S004: The UE and the access device negotiate an inactive eDRX configuration, where the inactive eDRX configuration may include inactive eDRX parameters. Specifically, the access device and the terminal negotiate the inactive eDRX configuration directly through one or more RRC signalings.

[0046] If the terminal is in an inactive state, the UE needs to receive paging not only from the core network but also from the RAN. The inactive state eDRX parameters may include: the inactive state eDRX cycle and / or the time domain starting position and / or window length (i.e., time length) of the inactive state PTW.

[0047] eDRX is also introduced for the inactive state, and the eDRX parameters of the inactive state are configured by the RAN. Moreover, the eDRX cycle of the inactive state is likely to be different from the eDRX cycle of the idle state.

[0048] Exemplarily, the eDRX cycle in the inactive state is shorter than the eDRX cycle in the idle state; and the length of the PTW in the inactive state is also configured by the RAN, and the PTW configured by the RAN and the PTW in the idle state have the same starting point but may have different lengths.

[0049] In some cases, when the eDRX cycle is long enough, a PTW is set within the eDRX cycle, and the terminal periodically switches between the awake state and the dormant state according to the DRX cycle within the PTW.

[0050] It is worth noting that: the negotiation between the UE and the access device for the eDRX configuration in the inactive state, the negotiation between the UE and the CN for the eDRX configuration in the idle state, and the access device issuing an indication of allowing the eDRX mechanism, the default DRX cycle and the hyperframe number (Hypersystem Frame Number, SFN) through the SIB can be independent of each other or performed in one process. For example, in one process, the network-side devices such as the CN and / or the access device and the UE can execute S001, S002 to S003 separately, or execute S004 separately. In other embodiments, the network-side devices such as the CN and / or the access device can execute S001 to S004 simultaneously.

[0051] In related technologies, the eDRX cycle configured for inactive UEs is typically relatively short, facilitating timely paging of the UE by the core network (CN) when data arrives, thereby improving UE reachability. However, to further reduce UE power consumption, the eDRX cycle has been increased. The corresponding UE Radio Resource Management (RRM) measurements also share the same power saving requirements.

[0052] As shown in FIG2A , an embodiment of the present disclosure provides a radio resource management (RRM) measurement method, which is performed by a UE and includes:

[0053] S1110: In response to the target eDRX cycle being greater than or equal to a preset value, perform RRM measurement within the target PTW.

[0054] The UE may be any UE supporting the eDRX mechanism.

[0055] Exemplarily, the UE may be various mobile phones, tablet computers or wearable devices, smart home devices, smart office devices, vehicle-mounted devices or industrial equipment, etc.

[0056] As another example, the UE may be a Reduced Capability (RedCap) UE, etc.

[0057] Here, the UE may be in a non-connected state, which may include: an RRC non-activated state and an RRC idle state. The RRC non-activated state may also be referred to as the non-activated state. If the UE supports the eDRX mechanism in the non-activated state, the eDRX parameters of the UE in the non-activated state are configured by the access network (Radio Access Network, RAN). Specifically, it is configured or determined by access devices such as evolved base stations (eNBs) and / or next-generation base stations (gNBs). The first eDRX parameter can be used to configure the eDRX cycle (i.e., the first eDRX cycle). Optionally, the RAN can also configure the DRX cycle (i.e., the first DRX cycle).

[0058] If the UE supports the eDRX mechanism in idle state (also called RRC idle state), the UE may receive the eDRX parameters configured by the CN.

[0059] The configured eDRX parameters are called second eDRX parameters, and the second eDRX parameters can be used to configure an eDRX cycle (ie, a second eDRX cycle). The CN can also configure a DRX cycle (ie, a second DRX cycle).

[0060] The aforementioned target eDRX cycle may be: the first eDRX cycle and / or the second eDRX cycle.

[0061] For example, if the UE is in an inactive state, the target eDRX cycle may be the first eDRX cycle and / or the second eDRX cycle.

[0062] For example, if the UE is in an idle state, the target eDRX cycle may be the second eDRX cycle.

[0063] The preset value here can be a value that allows PTW to be present within the target eDRX cycle. In other words, when the target eDRX cycle is greater than or equal to the preset value, PTW needs to be configured within the target eDRX cycle. Thus, when the target eDRX cycle is greater than or equal to 20.48 seconds, PTW can be present within the target eDRX cycle.

[0064] S1110 may include at least one of the following:

[0065] If the UE is in an inactive state and the first eDRX cycle in the inactive state is greater than or equal to a preset value, the UE performs RRM measurements within the target PTW;

[0066] If the UE is in an inactive state and the second eDRX cycle in the idle state is greater than or equal to a preset value, the UE performs RRM measurements within the target PTW;

[0067] If the UE is in an idle state and the second eDRX cycle in the idle state is greater than or equal to a preset value, the UE performs RRM measurement within the target PTW.

[0068] In some other embodiments, the target PTW may be a PTW determined according to the first eDRX parameter and / or the second eDRX parameter. For example, if the UE is configured with the first eDRX parameter, the target PTW may be the first PTW determined by the first eDRX parameter.

[0069] As another example, if the UE is configured with the second eDRX parameter but not the first eDRX parameter, the target PTW may be the second PTW indicated by the second eDRX parameter.

[0070] For another example, if the UE is configured with a first eDRX parameter and a second eDRX parameter, the target PTW may be determined in combination with the first eDRX parameter and the second eDRX parameter.

[0071] In summary, in the embodiments of the present disclosure, the target PTW is a portion of time domain resources in the time domain, which is usually a periodically distributed time window of equal or unequal length.

[0072] The RRM measurement here can be divided into: RRM measurement of the serving cell and / or RRM measurement of neighboring cells. Neighboring cells may include one or more of the following: same-frequency neighboring cells, different-frequency neighboring cells, different-system neighboring cells, etc.

[0073] RRM measurements for the serving cell may include: measurement of the serving cell's reference signal and cell evaluation based on the measurement data. RRM measurements for neighboring cells may include: cell identification (or discovery), measurement of neighboring cell reference signals, and cell evaluation based on the measurement values. The measurement data may be obtained from reference signal measurements.

[0074] Neighboring cells include but are not limited to: same-frequency neighboring cells, different-frequency neighboring cells and / or different-system neighboring cells.

[0075] The RRM measurement-related period may include:

[0076] Detection period (Tdetect), used to identify and evaluate neighboring cells;

[0077] Measurement period (Tmeasure), used for measuring the serving cell or neighboring cells;

[0078] The evaluation period (Tevaluate) is used to perform cell evaluation based on the measurement data obtained in the measurement period.

[0079] During the measurement period, the UE will measure the reference signal (Synchronization Signal and PBCH block, SSB) of the serving cell and / or the reference signal of the neighboring cell to obtain measurement data.

[0080] The reference signal includes but is not limited to:

[0081] Synchronization Signal and PBCH block (SSB), PBCH is the abbreviation of Physical Broadcast Channel;

[0082] Channel Status Information Reference Signal (CSI-RS).

[0083] The measurement data may include but is not limited to:

[0084] Measure signal value;

[0085] The comparison result of the measured signal value and the corresponding threshold value.

[0086] The measured signal value includes but is not limited to Reference Signal Received Power (RSRP) or Reference Signal Received Quality (RSRQ).

[0087] First, the RRM measurements performed in the entire time domain are limited to be performed within the target PTW, thereby reducing the RRM measurements in at least a portion of the time period, thereby saving the power consumption of the UE caused by the RRM measurements.

[0088] Secondly, since the UE periodically wakes up and sleeps according to the target eDRX cycle, and since the duration of the target eDRX cycle is relatively long, it will switch between the wake-up state and the sleep state according to the DRX cycle within the PTW corresponding to the executed target eDRX cycle, and will not wake up during the target eDRX cycle outside the PTW. If the RRM measurement is set outside the target PTW, the UE will need to exit the sleep state due to the RRM measurement in the time domain outside the target PTW, which may make the purpose of saving power consumption of the eDRX mechanism impossible to achieve or the effect less than ideal. Therefore, in the embodiment of the present disclosure, the RRM measurement is set within the PTW, that is, the UE needs to perform RRM measurement within the target PTW that needs to be woken up based on the eDRX mechanism, thereby saving the UE's power consumption and ensuring the execution effect of the eDRX mechanism. In some embodiments, the target eDRX cycle includes: the first eDRX cycle configured by the access network RAN, and / or the second eDRX cycle in which the UE is in an idle state.

[0089] As shown in FIG2B , an embodiment of the present disclosure provides an RRM measurement method, which is performed by a UE. The method includes:

[0090] S1210: In response to the UE being in an inactive state and the first eDRX cycle being greater than or equal to a preset value, perform RRM measurement within the target PTW.

[0091] When the UE is in an inactive state, the target eDRX cycle may be the first eDRX cycle configured by the RAN. The first eDRX cycle may be the eDRX cycle corresponding to the inactive state, that is, the eDRX cycle in the inactive state is greater than or equal to a preset value, and RRM measurements are performed within the target PTW.

[0092] The target PTW may be the first PTW corresponding to the first eDRX cycle or the second PTW in the idle state, or other PTWs.

[0093] If the target eDRX cycle is the first eDRX cycle, the target PTW may be determined based on the first eDRX parameters configured by the RAN. The window parameters may include: target PTW duration, target PTW distribution period, and / or different PTW window lengths at different time domain locations.

[0094] Similarly, for a UE in an inactive state, first, the RRM measurements performed in the entire time domain are limited to those performed within the target PTW, thereby reducing the RRM measurements in at least part of the time period, thereby saving the UE's power consumption due to the RRM measurements. Secondly, since the UE periodically wakes up and sleeps within the first PTW of the first eDRX cycle and does not wake up during the first eDRX cycle outside the first PTW, the UE needs to exit the sleep state due to RRM measurements in the time domain outside the first PTW, which may make the purpose of saving power consumption of the inactive eDRX mechanism unattainable or the effect less than ideal. In the embodiment of the present disclosure, the target PTW is associated with the first PTW. For example, this association is reflected in at least partial overlap in the time domain. Therefore, in the embodiment of the present disclosure, the RRM measurements are set within the target PTW associated with the first PTW, that is, the UE needs to perform RRM measurements during the time period when it needs to wake up based on the eDRX mechanism, thereby saving the UE's power consumption and ensuring the execution effect of the eDRX mechanism.

[0095] As shown in FIG2C , an embodiment of the present disclosure provides an RRM measurement method, which is performed by a UE. The method includes:

[0096] S1310: In response to the target eDRX cycle being greater than or equal to a preset value, determining a target PTW based on the first PTW and / or the second PTW; wherein the first PTW is configured by the RAN; and the second PTW is configured by the CN;

[0097] S1320: Perform RRM measurements within the target PTW.

[0098] Exemplarily, the first PTW is configured by the RAN using a first eDRX parameter; and the second PTW is configured by the CN using a second eDRX parameter.

[0099] In the embodiment of the present disclosure, if the UE is configured with both the first PTW and the second PTW, the target PTW may be determined based on the first PTW alone, the second PTW alone, or both the first PTW and the second PTW.

[0100] RRM measurements are performed within the target PTW rather than over the entire time domain.

[0101] In some embodiments, determining the target PTW according to the first PTW configured by the RAN and / or the second PTW configured by the CN includes at least one of the following:

[0102] Determine the target PTW as the second PTW;

[0103] According to the first PTW and the second PTW, determining the target PTW as a third PTW; wherein the period of the third PTW is the same as the period of the first PTW; and the window length of the third PTW is the same as the window length of the second PTW;

[0104] According to the first PTW and the second PTW, the target PTW is determined to be the second PTW and the first PTW that does not overlap with the second PTW.

[0105] In one embodiment, the first PTW is determined as the target PTW. This is equivalent to performing RRM measurement in an inactive PTW. In this case, the distribution period and window length of the target PTW in the time domain are determined by the first eDRX parameter.

[0106] In another embodiment, the second PTW is determined as the target PTW. Thus, when the UE is in an inactive or idle state, RRM measurements are performed only within the second PTW. Due to the association between the first eDRX parameter and the second eDRX parameter, the first eDRX cycle is less than or equal to the second eDRX cycle, and the first PTW is less than or equal to the second PTW. Thus, if any of the first PTW and the second PTW overlap in time domain, the time domain starting position of the first PTW must be aligned with the overlapping second PTW. Therefore, when the UE is in an inactive state and performs RRM measurements only within the second PTW, the time domain length of the RRM measurements can be further reduced compared to performing RRM measurements within the first PTW, thereby further saving UE power consumption.

[0107] In other embodiments, the target PTW is determined in conjunction with the first PTW and the second PTW. For example, the target PTW distribution period in the time domain is determined based on the first PTW distribution period defined by the first eDRX parameter, and the window length (i.e., time length) of each target PTW is determined based on the second PTW window length defined by the second eDRX parameter. Alternatively, the target PTW distribution period in the time domain may be determined based on the second eDRX parameter, and the target PTW window length may be determined based on the first eDRX parameter.

[0108] If the target PTW distribution period in the time domain is determined based on the first eDRX parameter, the target PTW occurrence period is the same as the first eDRX cycle and the first PTW. If the target PTW window length is determined based on the second eDRX parameter, the target PTW window length is equal to the second PTW window length.

[0109] If, based on the first and second PTWs, the target PTW is determined to be the second PTW and the first PTWs that do not overlap with the second PTW, then the target PTW may include all second PTWs and some first PTWs. The part of the first PTW included in the target PTW is the first PTW that does not overlap with the second PTW in the time domain. For example, if the first eDRX cycle is 1 / 2 of the second eDRX cycle, then the target PTW may include an odd number of first PTWs and all second PTWs. In this case, the target PTW includes two PTWs of different durations.

[0110] As shown in Figure 2D, PTW1 is the inactive PTW, also known as the first PTW. PTW2 is the idle PTW, also known as the second PTW. The first row of Figure 2D shows the time domain distribution of PTW1; the second row of Figure 2D shows the time domain distribution of PTW2 and the overlapping relationship between PTW1 and PTW2.

[0111] It can be seen that PTW2 in the idle state eDRX cycle is also longer than PTW1. Therefore, PTW1 is divided into two categories: one is PTW1 that overlaps with PTW2, and the other is PTW1 that does not overlap with PTW2.

[0112] The third row of FIG. 2D may be an example of a target PTW, that is, the target PTW may include all PTW2 and PTW1 that does not overlap with PTW2.

[0113] The fourth row of FIG. 2D may be an example of a target PTW, that is, the target PTW is PTW1.

[0114] As shown in FIG2E , an embodiment of the present disclosure provides a radio resource management (RRM) measurement method, which is performed by a UE and includes:

[0115] S1410: In response to the target eDRX cycle being greater than or equal to a preset value, perform RRM measurement within the target PTW;

[0116] S1420: Determine a DRX cycle according to a RAN paging cycle, a CN paging cycle, and / or a default paging cycle; wherein the RAN paging cycle is configured by the RAN and the CN paging cycle is configured by the CN;

[0117] S1430: Determine measurement parameters for RRM measurement according to the DRX cycle.

[0118] The RAN paging cycle is configured by the RAN, for example, the RAN sends the RAN paging cycle to the UE via RRC signaling. The UE monitors RAN paging according to the RAN paging cycle within the first PTW.

[0119] The CN paging cycle may be configured by the CN. After receiving the CN paging cycle, the UE may monitor CN paging according to the CN paging cycle within the second PTW.

[0120] The default paging cycle may be a paging cycle for broadcasting system messages of the RAN, and the paging cycle may be used to monitor CN paging and / or RAN paging.

[0121] In an embodiment of the present disclosure, a DRX cycle is determined based on a RAN paging cycle, a CN paging cycle, and / or a default paging cycle. The DRX cycle may be used to determine measurement parameters for RRM measurements, for example, to determine at least a cycle related to RRM measurements. The cycle related to RRM measurements may include a detection cycle, a measurement cycle, and / or an evaluation cycle.

[0122] That is, in the embodiment of the present disclosure, the DRX cycle is first determined, and then the measurement parameters for performing RRM measurement within the target PTW are determined according to the DRX cycle.

[0123] It is worth noting that this embodiment can be implemented alone or in combination with the aforementioned embodiments. For example, it can be implemented in combination with the RRM measurement method shown in FIG2C , that is, the target PTW is determined according to the method shown in FIG2C , and the measurement parameters of the RRM measurement are determined according to the method shown in FIG2E .

[0124] In some embodiments, determining the DRX cycle according to the RAN paging cycle, the CN paging cycle and / or the default paging cycle includes:

[0125] When performing RRM measurement in the target PTW, the DRX cycle is determined according to the first PTW and the second PTW, and a RAN paging cycle, a CN paging cycle and / or a default paging cycle.

[0126] In the embodiment of the present disclosure, whether the current target PTW corresponds to the first PTW and the second PTW at the same time can be determined. If the current target PTW corresponds to the first PTW and the second PTW at the same time, the measurement parameters of the RRM measurement within different time ranges within the target PTW can be determined based on the overlapping relationship between the first PTW and the second PTW in the time domain, and further combined with the RAN paging cycle, the CN paging cycle and / or the default paging cycle.

[0127] In some embodiments, when performing the RRM measurement within the target PTW, determining the DRX cycle according to the first PTW and the second PTW, and a RAN paging cycle, a CN paging cycle, and / or a default paging cycle includes at least one of the following:

[0128] For RRM measurement in a first PTW that does not overlap with the second PTW in time domain, determining the DRX cycle according to the RAN paging cycle and the default paging cycle;

[0129] For RRM measurement in a first PTW that has a time domain overlap with the second PTW, determining the DRX cycle according to the RAN paging cycle, the CN paging cycle, and the default paging cycle;

[0130] For the second PTW that has a time domain overlap with the first PTW, excluding the first PTW, the DRX cycle is determined according to the CN paging cycle and the default paging cycle.

[0131] In some embodiments, when the DRX cycle is determined based on two or three of the RAN paging cycle, the default paging cycle, and the CN paging cycle, the larger or maximum of the two or three of the RAN paging cycle, the default paging cycle, and the CN paging cycle may be selected as the DRX cycle based on the time domain overlap between the first PTW and the second PTW. By further determining the measurement parameters for the RRM measurement in this manner, the number of RRM measurements can be further reduced.

[0132] In other embodiments, when the DRX cycle is determined based on two or three of the RAN paging cycle, the default paging cycle, and the CN paging cycle, the smaller or smallest of the two or three of the RAN paging cycle, the default paging cycle, and the CN paging cycle may be selected as the DRX cycle in combination with the overlap between the first PTW and the second PTW in the time domain. By further determining the measurement parameters for RRM measurement in this manner, better RRM measurements can be performed on the serving cell and / or neighboring cells.

[0133] For example, there are multiple ways to determine the DRX cycle based on the overlapping relationship between the first PTW and the second PTW in the time domain. These multiple ways are not prioritized and are numbered and described below for convenience:

[0134] Method 1: For RRM measurements within the first PTW that does not overlap with the second PTW, the DRX cycle is determined to be the minimum of the RAN paging cycle and the default paging cycle.

[0135] Method 2: For RRM measurements within the first PTW that has a time domain overlap with the second PTW, the DRX cycle is determined to be the minimum of the RAN paging cycle, the CN paging cycle, and the default paging cycle;

[0136] Method three: for a second PTW that has a time domain overlap with the first PTW, within a time range excluding the first PTW, the DRX cycle is determined to be the smaller of the CN paging cycle and the default paging cycle.

[0137] Any two or three of Methods 1 to 3 may be used in combination.

[0138] Method 1 for determining the DRX cycle in the embodiment of the present disclosure may be used for any of the aforementioned target PTWs. For example, if the target PTW is the first PTW, Method 1 and Method 2 may be used to determine the DRX cycle related to the measurement parameters for RRM measurement.

[0139] If the target PTW is the second PTW, a combination of the second method and the third method may be used to determine the DRX cycle.

[0140] If the target PTW is a third PTW, or a second PTW and a first PTW that does not overlap with the second PTW in time domain, methods 1 to 3 may be used to jointly determine the DRX cycles within different target PTWs or the DRX cycles within different time ranges within the same target PTW. In this case, multiple sets of measurement parameters for RRM measurements within the target PTW may exist, and the different sets of measurement parameters may involve different detection periods, measurement periods, and / or evaluation periods, in part or in whole.

[0141] In some embodiments, determining the DRX cycle according to the RAN paging cycle, the CN paging cycle, and / or the default paging cycle includes at least one of the following:

[0142] Determining the DRX cycle according to the RAN paging cycle, the CN paging cycle, and the default paging cycle;

[0143] determining the DRX cycle according to the RAN paging cycle and the default paging cycle;

[0144] Determining the DRX cycle according to the CN paging cycle and the default paging cycle;

[0145] The DRX cycle is determined by the RAN paging cycle, the CN paging cycle, or a default paging cycle.

[0146] In some embodiments, when the DRX cycle is determined based on two or three of the RAN paging cycle, the default paging cycle, and the CN paging cycle, the larger or the maximum of the two or three of the RAN paging cycle, the default paging cycle, and the CN paging cycle may be selected as the DRX cycle. By further determining the measurement parameters for the RRM measurement in this manner, the number of RRM measurements can be further reduced.

[0147] In other embodiments, when the DRX cycle is determined based on two or three of the RAN paging cycle, the default paging cycle, and the CN paging cycle, the smaller or the smallest of the two or three of the RAN paging cycle, the default paging cycle, and the CN paging cycle may be selected as the DRX cycle. By further determining the measurement parameters for the RRM measurement in this manner, better RRM measurements can be performed on the serving cell and / or neighboring cells.

[0148] Exemplarily, determining the DRX cycle according to the RAN paging cycle, the CN paging cycle, and / or the default paging cycle includes at least one of the following:

[0149] Determine the DRX cycle as the minimum of the RAN paging cycle, the CN paging cycle, and the default paging cycle;

[0150] Determine the DRX cycle as the smaller of the RAN paging cycle and the default paging cycle;

[0151] Determine the DRX cycle as the smaller of the CN paging cycle and the default paging cycle;

[0152] The DRX cycle is determined to be a RAN paging cycle, a CN paging cycle, or a default paging cycle.

[0153] In the disclosed embodiments, the DRX cycles for the measurement parameters of RRM measurements within the target PTW are the same. That is, the DRX cycles corresponding to RRM measurements within different target PTWs or within different time ranges of the same target PTW are the same. Thus, within different target PTWs or within different time ranges of the same target PTW, the measurement parameters used for RRM measurements can be the same, that is, the detection period, measurement period, and evaluation period are all the same.

[0154] In some embodiments, the preset value is 20.48s.

[0155] If the first eDRX cycle and / or the second eDRX cycle is greater than or equal to 20.48s, it means that a PTW is set in the first eDRX cycle and / or the second eDRX cycle. At this time, RRM measurements can be limited to the target PTW, thereby reducing unnecessary RRM measurements, further saving power consumption generated by RRM measurements, and extending the UE standby time.

[0156] In some embodiments, a network device (e.g., a RAN) may configure an inactive eDRX cycle (eDRX cycle) greater than 10.24 seconds for an inactive UE. It is understood that, in some embodiments, an inactive UE may receive both an inactive eDRX cycle and an idle eDRX cycle.

[0157] The UE may perform RRM measurement requirements under the eDRX mechanism based on any of the following methods.

[0158] Method 1: For an inactive mode UE configured with an inactive eDRX cycle greater than 10.24s, the UE in inactive mode performs RRM measurements based only on the received RAN paging cycle.

[0159] As an embodiment, RRM measurements (serving cell and / or neighbor cell measurements) are limited to the PTW that needs to monitor RAN paging, ie, the received CN paging cycle is ignored.

[0160] As an embodiment: RRM measurements (serving cell and / or neighbor cell measurements) are limited to PTWs in inactive mode.

[0161] As an embodiment, the DRX cycle referenced by the RRM measurement (serving cell and / or neighbor cell measurement) is the radio access network paging cycle (RAN paging cycle).

[0162] It is worth noting that the contents of each row and / or column in the above table can be implemented separately or in any combination without conflict.

[0163] In the above table, Nserv means: similar to a counter. If the UE evaluates that the serving cell does not meet the S criterion within Nserv consecutive DRX cycles, the UE will start measurement of all neighbor cells indicated by the serving cell regardless of the current rules restricting UE measurement activities.

[0164] Tdetect: detection period;

[0165] Tmeasure: measurement period;

[0166] Tevaluate: Evaluation cycle.

[0167] Mode 2: For a UE in inactive mode, an inactive eDRX cycle greater than 10.24s is configured. An inactive PTW is configured within the inactive eDRX cycle, and the inactive PTW is recorded as PTW1. A UE in idle mode is configured with an idle eDRX cycle; if the idle eDRX cycle is greater than 10.24s, an idle PTW is configured within the idle eDRX cycle, and the idle PTW is recorded as PTW2. It is understandable that, in some embodiments, a UE in inactive mode can receive both an inactive eDRX cycle and an idle eDRX cycle.

[0168] As an embodiment, in a scenario where both PTW1 and PTW2 are configured on a network device, the UE limits RRM measurements to PTW1 and / or PTW2. The network device may include a RAN device (or access device) configured with PTW1. The network device may also include a CN device (e.g., MME or AMF) configured with PTW2.

[0169] As an embodiment, in a scenario where the network configures both PTW1 and PTW2, the UE limits RRM measurements to a third PTW, where the third PTW is obtained based on a combination of the eDRX parameters for the inactive mode and the eDRX parameters for the idle mode. For example, the period of the third PTW is determined by the eDRX period provided by the eDRX parameters for the inactive mode, while the window length of the third PTW is determined by the window length provided by the eDRX parameters for the idle mode.

[0170] As an embodiment, for a scenario where the network configures both PTW1 and PTW2, the DRX cycle (T) for the UE to perform RRM measurement may be a cycle for the UE to monitor CN paging or a cycle for the UE to monitor RAN paging, or a cycle for the UE to monitor both CN paging and RAN paging.

[0171] When PTW1 and PTW2 conflict (overlap in the time domain), the window of PTW2 is used as the boundary. Within the overlap range of PTW1 and PTW2, for example, the length is within PTW1 or PTW2, that is, the cross-line period in Figure 2D, T = min{inactive DRX, idle DRX, default paging cycle}, and

[0172] As shown in Figure 2D, outside the overlap range of PTW1 and PTW2, in the PTW that only monitors CN paging. In the PTW2-PTW1 range, that is, the remaining range of PTW2 except the overlap with PTW1, that is, the right-slashed part on the right side of the cross period, T = min{idle DRX, default paging cycle}. Outside the overlap range of PTW1 and PTW2, in the PTW1 that only monitors RAN paging (outside PTW2, the UE only performs measurements in PTW1, that is, the left-slashed part), T = min{inactive DXR}. When PTW1 and PTW2 conflict (there is overlap in the time domain), use the PTW1 window as the boundary,

[0173] Within PTW1 (overlap window), T=min{inactive mode DRX cycle, default paging cycle, idle mode DRX cycle}, and outside PTW1 (non-overlap part), the UE only performs measurements within PTW1, T=min{inactive DXR}.

[0174] Idle DRX is the aforementioned CN paging cycle. Inactive DXR is the aforementioned RAN paging cycle. Default paging cycle is the aforementioned default paging cycle.

[0175] The UE performs cell selection / reselection measurement of an inactive mode UE based on T obtained by the above judgment.

[0176] It is worth noting that the contents of each row and / or column in the above table can be implemented separately or in any combination without conflict.

[0177] In the above table, Nserv means: similar to a counter. If the UE evaluates that the serving cell does not meet the S criterion within Nserv consecutive DRX cycles, the UE will start measurement of all neighbor cells indicated by the serving cell regardless of the current rules restricting UE measurement activities.

[0178] Tdetect: detection period;

[0179] Tmeasure: measurement period;

[0180] Tevaluate: Evaluation cycle.

[0181] It should be noted that when the UE performs RRM measurements, the measurements of the serving cell and the neighboring cell may be based on the same measurement requirements, that is, the UE uses method 1 to determine the measurement parameters for both the serving cell and the neighboring cell, or uses method 2 to determine the measurement parameters. Optionally, when the UE performs RRM measurements, that is, the UE uses method 1 to determine the measurement parameters for the serving cell and method 2 to determine the measurement parameters for the neighboring cell. Alternatively, the UE uses method 2 to determine the measurement parameters for the serving cell and method 1 to determine the measurement parameters for the neighboring cell. Alternatively, the UE uses method 1 or method 2 to determine the measurement parameters for the serving cell and other methods to determine the measurement parameters for the neighboring cell. Alternatively, the UE uses method 1 or method 2 to determine the measurement parameters for the neighboring cell and other methods to determine the measurement parameters for the serving cell. Alternatively, the UE uses method 1 or method 2 to determine the measurement parameters for the neighboring cell and other methods to determine the measurement parameters for the serving cell.
