Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of wireless communication, and more particularly to a radio resource management (RRM) measurement method and device, a communication device, and a storage medium. BACKGROUND

[0002] In order to balance low power consumption and services with certain latency requirements, a terminal, also known as a user equipment (UE), introduces an extended discontinuous reception (eDRX) mechanism. After the terminal enters the eDRX mechanism, the terminal will wake up and sleep in the eDRX cycle.

[0003] If the eDRX cycle is long enough, there is a paging time window (PTW) in each eDRX cycle. The terminal wakes up and sleeps according to a discontinuous reception (DRX) cycle in the PTW, and listens to a paging channel when waking up to receive downlink data. The terminal is in a sleep state for the rest of the time. If the eDRX cycle is short, the eDRX cycle is not configured with a PTW, and the network device will consider that the terminal does not sleep, i.e., the terminal is always reachable. SUMMARY

[0004] Embodiments of the present disclosure provide a RRM measurement method and device, a communication device, and a storage medium.

[0005] A first aspect of embodiments of the present disclosure provides a radio resource management (RRM) measurement method, wherein the method is performed by a UE, and the method comprises:

[0006] In response to a target eDRX cycle being greater than or equal to a preset value, performing RRM measurement in a target paging time window (PTW). A second aspect of embodiments of the present disclosure provides a radio resource management (RRM) measurement device, wherein the device comprises:

[0007] An execution module configured to perform RRM measurement in a target paging time window (PTW) in response to a target eDRX cycle being greater than or equal to a preset value.

[0008] A third aspect of embodiments of the present disclosure provides a communication device, comprising a processor, a transceiver, a memory, and an executable program stored on the memory and capable of being executed by the processor, wherein the processor executes the executable program to perform the RRM measurement method of any of the technical solutions of the first aspect.

[0009] The fourth aspect of the embodiments of the present disclosure provides a computer storage medium, which stores an executable program; the executable program, when executed by a processor, can implement the RRM measurement method according to any of the first aspect.

[0010] The technical solution provided by the embodiments of the present disclosure first limits the RRM measurement performed in the entire time domain to be performed in the target PTW, so as to reduce the RRM measurement in at least part of the time period, and thus the power consumption of the UE caused by the RRM measurement can be saved.

[0011] Secondly, since the UE performs periodic wake-up and sleep according to the target eDRX cycle, and since the length of the target eDRX cycle is relatively large, the UE performs switching between the wake-up state and the sleep state according to the DRX cycle in the PTW corresponding to the target eDRX cycle to be performed, and does not wake up in the target eDRX cycle outside the PTW. If the RRM measurement is set outside the target PTW, the UE needs to exit the sleep state for the RRM measurement in the time domain outside the target PTW, which may make it impossible to achieve or not ideal to achieve the purpose of saving power consumption by the eDRX mechanism. Therefore, in the embodiments of the present disclosure, the RRM measurement is set in the PTW, that is, the UE needs to perform the RRM measurement in the target PTW in which the UE needs to wake up based on the eDRX mechanism, so as to save the power consumption of the UE and ensure the execution effect of the eDRX mechanism.

[0027] Please refer to FIG. 1A This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. FIG. 1AAs shown, the wireless communication system is a communication system based on cellular mobile communication technology, which can include a plurality of UEs 11 and a plurality of access devices 12. In some embodiments, the communication system can further include one or more core network devices, which are not shown in FIG. 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), a Policy Control Function (PCF), and the like.

[0028] The UE 11 can be a device that provides voice and / or data connectivity to a user. The UE 11 can communicate with one or more core networks via a Radio Access Network (RAN), and the UE 11 can be an Internet of Things UE, such as a sensor device, a mobile phone (or called cellular phone), and a computer with an Internet of Things UE, for example, which can be fixed, portable, pocket, hand-held, computer-embedded, or vehicle-mounted. For example, a Station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user equipment (UE). Alternatively, the UE 11 can also be a device of an unmanned aerial vehicle. Alternatively, the UE 11 can also be a vehicle-mounted device, which can be a vehicle-mounted computer with wireless communication function, or a wireless communication device externally connected to the vehicle-mounted computer. Alternatively, the UE 11 can also be a roadside device, which can be a street lamp, a signal lamp, or other roadside devices with wireless communication function, and the like.

[0029] The access device 12 can be a network side device in a wireless communication system. The wireless communication system can be a 4th generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system, or the wireless communication system can be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system can be a further next generation system of the 5G system. In the 5G system, the access network can be referred to as a new generation radio access network (NG-RAN). Alternatively, the MTC system.

[0030] The access device 12 can be an evolved access device (eNB) used in a 4G system. Alternatively, the access device 12 can be an access device (gNB) using a centralized and distributed architecture in a 5G system. When the access device 12 uses a centralized and distributed architecture, it generally includes a central unit (CU) and at least two distributed units (DUs). The central unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a media access control (MAC) layer. The distributed unit is provided with a physical (PHY) layer protocol stack. The specific implementation of the access device 12 is not limited in the embodiments of the present disclosure.

[0031] The access device 12 and the UE 11 can establish a wireless connection through a wireless air interface. In different embodiments, the wireless air interface is a wireless air interface based on a 4th generation mobile communication network technology (4G) standard; or the wireless air interface is a wireless air interface based on a 5th generation mobile communication network technology (5G) standard, such as a new radio (NR); or the wireless air interface can also be a wireless air interface based on a further next generation mobile communication network technology standard of the 5G.

[0032] In the related art, the eDRX parameter of the idle state of the terminal is negotiated by the terminal and the core network through a NAS message, and is completely transparent to the access device such as a base station.

[0033] In New Radio (NR), an inactive state is also introduced. At this time, the UE needs to receive not only the core network paging, but also the RAN paging. In the case of Reduced Capability (Redcap), eDRX will also be introduced for the inactive state, and the eDRX parameters of the inactive state are configured by the RAN, and the eDRX period of the inactive state and the eDRX period of the idle state may be different. For example, the eDRX period of the inactive state is smaller than the eDRX period of the idle state. And the PTW for the inactive state is also configured by the RAN. In one example, the PTW for the inactive state and the PTW for the idle state are configured by the RAN, and the start point is the same, and the length can be different.

[0034] Reference FIG. 1B It can be seen that the eDRX period includes a PTW; for example, one eDRX period includes one PTW. One PTW includes one or more DRX periods. The duration of the DRX period is less than the duration of the eDRX period.

[0035] For example, when the eDRX period is greater than 10.24s, then the PTW of the eDRX period includes multiple DRXs.

[0036] Before the terminal enters the eDRX mechanism, the terminal will interact with the network side through related signaling.

[0037] For example, as shown in FIG. 1C The terminal will interact with the network side through related signaling, which can include:

[0038] S001: The access device sends a system information block (SIB) to the UE, which includes an indication of allowing the eDRX mechanism, a default DRX period, and a hyper system frame number (SFN). After the UE receives the SIB, if the SIB includes an indication that the UE allows the eDRX mechanism, the UE will determine the superframe in which to start performing the eDRX mechanism according to the hyper system frame number. When the UE performs the eDRX mechanism, it can listen to the CN paging according to the default DRX period according to the agreement between the UE and the access device. The access device can be various types of access devices as shown in FIG. 1A .

[0039] In some cases, the SIB can also include a default DRX period. The default DRX period can also be referred to as a default paging period.

[0040] S002: The UE and the core network (CN) negotiate the idle state eDRX configuration, which can include idle state eDRX parameters. Specifically, the UE sends UE-specific DRX parameters (UE-specific DRX) and / or preferable eDRX parameters when sending an attach request or a tracking area update (TAU) request to the MME.

[0041] After the CN receives the above-mentioned attach request or TAU request, the eDRX configuration is issued to the UE; the eDRX configuration carries one or more eDRX parameters mentioned above. The eDRX parameters include one or more of the following: eDRX cycle and / or time domain starting position and window length of PTW.

[0042] S003: After completing the idle state eDRX configuration and the terminal enters the eDRX mechanism, the CN can send the NG paging signaling for the RRC inactive state and the CN assistance information for the RRC inactive state, which can include the eDRX configuration and / or the DRX configuration. The DRX configuration can include the CN configured DRX cycle. The CN performs paging according to the eDRX configuration; the access device forwards the CN paging to the UE after receiving the CN paging issued by the MME.

[0043] The idle state eDRX parameters are transparently transmitted to the UE through the access device. For example, the core network device such as the mobile management function (MME) or AMF of the CN sends the eDRX parameters of the eDRX mechanism to the UE through the access device. In some embodiments, the MME can be replaced by a functional network element such as the CN AMF. The idle state eDRX parameters are negotiated between the UE and the core network through NAS messages, and the access device is completely transparent.

[0044] S004: The UE and the access device negotiate the inactive state eDRX configuration, which can include inactive state eDRX parameters. Specifically, the access device and the terminal directly negotiate the inactive state eDRX configuration through one or more RRC signaling.

[0045] If the terminal is in the inactive state. At this time, the UE not only needs to receive the paging from the core network, but also needs to receive the RAN paging. The inactive state eDRX parameters can include the inactive state eDRX cycle and / or the time domain starting position and / or window length (i.e. length) of the inactive state PTW.

[0046] eDRX is also introduced for the inactive state, and the eDRX parameters for the inactive state are configured by the RAN, and the eDRX cycle for the inactive state and the eDRX cycle for the idle state are likely to be different.

[0047] Exemplarily, the eDRX cycle for the inactive state is smaller than the eDRX cycle for the idle state; and the length of the PTW for the inactive state is also configured by the RAN, and the RAN-configured PTW and the PTW for the idle state have the same starting point, and the lengths can be different.

[0048] In some cases, when the eDRX cycle is long enough, the PTW is set within the eDRX cycle, and the terminal performs periodic switching between the wake-up state and the sleep state within the PTW according to the DRX cycle.

[0049] It is worth noting that the negotiation between the UE and the access device for the eDRX configuration for the inactive state, the negotiation between the UE and the CN for the eDRX configuration for the idle state, and the indication of the allowed eDRX mechanism, the default DRX cycle, and the hyper system frame number (SFN) issued by the access device can be independent of each other, or can be performed in one process. Exemplarily, in one process, the network side device such as the CN and / or the access device, and the UE can separately perform S001, S002 to S003, or separately perform S004. In some other embodiments, the CN and / or the access device of the network side device can simultaneously perform S001 to S004.

[0050] In the related art, the eDRX cycle configured for the UE for the inactive state is generally small, which facilitates the core network (CN) to timely page the UE when data reaches, thereby improving the reachability of the UE. However, considering further power saving of the UE, the eDRX cycle is further increased. The radio resource management (RRM) measurement of the UE adapted thereto also has the same power saving requirement.

[0051] As shown in FIG. 1, the present disclosure provides a radio resource management (RRM) measurement method, wherein the method is performed by a UE, and the method comprises the following steps. FIG. 2A

[0052] S1110: In response to the target eDRX cycle being greater than or equal to a preset value, performing RRM measurement within the target PTW.

[0053] The UE can be various UEs supporting the eDRX mechanism.

[0054] ​Exemplarily, the UE can be various mobile phones, tablets or wearable devices, smart home devices, smart office devices, in-vehicle devices, industrial devices, etc.

[0055] Exemplarily, the UE can be a Reduced Capability (RedCap) UE, etc.

[0056] Here, the UE can be in a non-connected state, which can include an RRC inactive state, an RRC idle state. The RRC inactive state can also be referred to as an inactive state. If the UE supports an eDRX mechanism in the inactive state, the eDRX parameters in the inactive state of the UE are configured by the Radio Access Network (RAN). Specifically, configured or determined by an access device such as an evolved NodeB (eNB) and / or a next-generation NodeB (gNB). The first eDRX parameter can be used to configure an eDRX cycle (i.e., a first eDRX cycle). Optionally, the RAN can also configure a DRX cycle (i.e., a first DRX cycle).

[0057] If the UE supports an eDRX mechanism in the idle state (also referred to as an RRC idle state), the UE can receive eDRX parameters configured by the CN. In the embodiments of the present disclosure,

[0058] The configured eDRX parameters are referred to as second eDRX parameters, which can be used to configure an eDRX cycle (i.e., a second eDRX cycle). The CN can also configure a DRX cycle (i.e., a second DRX cycle).

[0059] The foregoing target eDRX cycle can be the first eDRX cycle and / or the second eDRX cycle.

[0060] For example, when the UE is in the inactive state, the foregoing target eDRX cycle can be the first eDRX cycle and / or the second eDRX cycle.

[0061] For example, when the UE is in the idle state, the foregoing target eDRX cycle can be the second eDRX cycle.

[0062] Here, the preset value can be a value such that the target eDRX cycle has a PTW. In other words, when the target eDRX cycle is greater than or equal to the preset value, a PTW needs to be configured in the target eDRX cycle. In this way, when the target eDRX cycle is greater than or equal to 20.48s, the target eDRX cycle can have a PTW.

[0063] S1110 can include at least one of the following:

[0064] If the UE is in the inactive state and the first eDRX cycle of the inactive state is greater than or equal to a preset value, the UE performs RRM measurement within a target PTW.

[0065] If the UE is in the inactive state and the second eDRX cycle of the idle state is greater than or equal to a preset value, the UE performs RRM measurement within a target PTW.

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

[0067] In some embodiments, the target PTW can 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 can be a first PTW determined according to the first eDRX parameter.

[0068] For another example, if the UE is configured with the second eDRX parameter and not configured with the first eDRX parameter, the target PTW can be a second PTW indicated by the second eDRX parameter.

[0069] For another example, if the UE is configured with the first eDRX parameter and the second eDRX parameter, the target PTW can be determined in combination of the first eDRX parameter and the second eDRX parameter.

[0070] In summary, in the embodiments of the present disclosure, the target PTW is a part of time domain resources in the time domain, and is usually a periodic time window with equal or unequal length.

[0071] The RRM measurement can include RRM measurement of a serving cell and / or RRM measurement of a neighbor cell. The neighbor cell can include one or more of the following: an intra-frequency neighbor cell, an inter-frequency neighbor cell, an inter-system neighbor cell, etc.

[0072] The RRM measurement of the serving cell can include measurement of a reference signal of the serving cell and cell evaluation based on the measurement data. The RRM measurement of the neighbor cell can include cell identification (or discovery), measurement of a reference signal of the neighbor cell, and cell evaluation based on the measurement value. The measurement data can be obtained by measuring the reference signal.

[0073] The neighbor cell includes but is not limited to: an intra-frequency neighbor cell, an inter-frequency neighbor cell, and / or an inter-system neighbor cell.

[0074] The period related to the RRM measurement can include:

[0075] A detection period (Tdetect) for identifying and evaluating a neighbor cell;

[0076] A measurement period (Tmeasure) for measurement of a serving cell or a neighbor cell.

[0077] An evaluation period (T evaluate ) for performing cell evaluation based on measurement data obtained from the measurement period.

[0078] Within the measurement period, the UE will perform measurements on reference signals (Synchronization Signal and PBCH block, SSB) of the serving cell and / or reference signals of the neighbor cells, thus obtaining measurement data.

[0079] The reference signals include but are not limited to:

[0080] Synchronization Signal and PBCH block (SSB), where PBCH is the abbreviation of Physical Broadcast Channel;

[0081] Channel Status Information Reference Signal (CSI-RS).

[0082] The measurement data can include but are not limited to:

[0083] Measured signal value;

[0084] Comparison result of the measured signal value and the corresponding threshold.

[0085] The measured signal value includes but is not limited to Reference Signal Received Power (RSRP) or Reference Signal Received Quality (RSRQ).

[0086] Firstly, the RRM measurement performed in the whole time domain is limited to be performed within the target PTW, thus reducing the RRM measurement in at least part of the period, and thus the power consumption of the UE caused by the RRM measurement can be saved.

[0087] Secondly, since the UE performs periodic wake-up and sleep according to the target eDRX cycle, and the length of the target eDRX cycle is relatively large, the UE performs switching between the wake-up state and the sleep state according to the DRX cycle within the PTW corresponding to the target eDRX cycle, and does not wake up within the target eDRX cycle outside the PTW. If the RRM measurement is set outside the target PTW, the UE needs to exit the sleep state for RRM measurement in the time domain outside the target PTW, which may affect the power consumption saving purpose of the eDRX mechanism or the effect is not ideal. Therefore, in the embodiments 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 wake up based on the eDRX mechanism, so as to save the power consumption of the UE and ensure the execution effect of the eDRX mechanism. In some embodiments, the target eDRX cycle includes: a first eDRX cycle configured by the access network RAN, and / or a second eDRX cycle in an idle state of the UE.

[0088] As shown in FIG. 2B , the embodiments of the present disclosure provide a RRM measurement method, performed by a UE, and the method comprises:

[0089] S1210: performing RRM measurement within the target PTW in response to that the UE is in the inactive state and the first eDRX cycle is greater than or equal to a preset value.

[0090] When the UE is in the inactive state, the target eDRX cycle can be the first eDRX cycle configured by the RAN. The first eDRX cycle can 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 the RRM measurement is performed within the target PTW.

[0091] The target PTW can be the first PTW corresponding to the first eDRX cycle or the second PTW in the idle state, or other PTWs.

[0092] If the target eDRX cycle is the first eDRX cycle, the target PTW can be determined according to the first eDRX parameters configured by the RAN. The window parameters can include: the length of the target PTW, the distribution period of the target PTW, and / or different window lengths of the PTW in different time domains, etc.

[0093] Similarly, for the UE in the inactive state, firstly, the RRM measurement performed in the entire time domain is limited to be performed in the target PTW, so as to reduce the RRM measurement in at least part of the time period, and thus the power consumption of the UE caused by the RRM measurement can be saved. Secondly, since the UE is periodically woken up and sleeps in the first PTW according to the first eDRX cycle, and does not wake up in the first eDRX cycle outside the first PTW, the UE needs to exit the sleep state for the RRM measurement in the time domain outside the first PTW, which may cause the inactive eDRX mechanism to fail to achieve or not achieve the ideal effect of saving power consumption. In the embodiment of the present disclosure, the target PTW is associated with the first PTW, for example, the association is reflected in that the time domain at least partially overlaps, and therefore in the embodiment of the present disclosure, the RRM measurement is set in the target PTW associated with the first PTW, that is, the UE needs to perform the RRM measurement in the time period in which the UE needs to wake up based on the eDRX mechanism, so as to save the power consumption of the UE and ensure the execution effect of the eDRX mechanism.

[0094] As shown in FIG. 2C , the embodiment of the present disclosure provides a RRM measurement method, which is performed by a UE, and the method comprises:

[0095] S1310: in response to the target eDRX cycle being greater than or equal to a preset value, determining a target PTW according to the first PTW and / or the second PTW; wherein the first PTW is configured by a RAN; and the second PTW is configured by a CN;

[0096] S1320: performing RRM measurement in the target PTW.

[0097] Exemplarily, the first PTW is configured by the RAN through a first eDRX parameter; and the second PTW is configured by the CN through a second eDRX parameter.

[0098] In the embodiment of the present disclosure, if the UE is configured with the first PTW and the second PTW at the same time, the target PTW can be determined according to the first PTW alone, according to the second PTW alone, or according to the first PTW and the second PTW at the same time.

[0099] The RRM measurement is performed in the target PTW, rather than in the entire time domain.

[0100] In some embodiments, the target PTW is determined according to the first PTW configured by the RAN and / or the second PTW configured by the CN, and the determination comprises at least one of the following:

[0101] The target PTW is determined as the second PTW;

[0102] According to the first PTW and the second PTW, the target PTW is determined as the 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.

[0103] According to the first PTW and the second PTW, the target PTW is determined as the second PTW and the first PTW which does not overlap with the second PTW.

[0104] In one embodiment, the first PTW is determined as the target PTW, so as to perform the RRM measurement in the PTW in the inactive state, wherein the distribution period and the window length of the target PTW in the time domain are determined by the first eDRX parameter.

[0105] In another embodiment, the second PTW is determined as the target PTW, so as to perform the RRM measurement in the second PTW when the UE is in the inactive state or the idle state. Due to the correlation between the first eDRX parameter and the second eDRX parameter, the first eDRX period is less than or equal to the second eDRX period, and the first PTW is less than or equal to the second PTW. Therefore, if there is a time domain overlap between any first PTW and the second PTW, the time domain starting position of the first PTW is aligned with the second PTW which has the overlap. Therefore, when the UE performs the RRM measurement in the second PTW in the inactive state, the time domain length of the RRM measurement can be further reduced compared with the RRM measurement in the first PTW, so as to further save the power consumption of the UE.

[0106] In some other embodiments, the target PTW is determined in combination with the first PTW and the second PTW. For example, according to the distribution period of the first PTW defined by the first eDRX parameter, the distribution period of the target PTW in the time domain is determined, and according to the window length of the second PTW defined by the second eDRX parameter, the window length (i.e. the time length) of each target PTW is determined. In addition, the distribution period of the target PTW in the time domain can also be determined according to the second eDRX parameter, and the window length of the target PTW can be determined according to the first eDRX parameter.

[0107] If the distribution period of the target PTW in the time domain is determined according to the first eDRX parameter, the occurrence period of the target PTW is the same as the first eDRX period and the first PTW. If the window length of the target PTW is determined according to the second eDRX parameter, the window length of the target PTW is equal to the window length of the second PTW.

[0108] If, based on the first PTW and the second PTW, the target PTW is determined to be the second PTW and a first PTW that does not overlap with the second PTW, then the target PTW may include all of the second PTW and a portion of the first PTW. The portion of the first PTW included in the target PTW is a first PTW that does not have a temporal overlap with the second PTW. For example, if the first eDRX period is equal to half of the second eDRX period, then the target PTW may include an odd number of first PTWs and all of the second PTWs. In summary, in this case, the target PTW has two PTWs of different durations.

[0109] like FIG. 2D As shown, PTW1 is the inactive PTW, also known as the first PTW. PTW2 is the idle PTW, also known as the second PTW. FIG. 2D The first row shows the distribution of PTW1 in the time domain; FIG. 2D The second row shows the temporal distribution of PTW2 and the overlap between PTW1 and PTW2.

[0110] It is evident that PTW2 is longer than PTW1 within the idle eDRX cycle. Thus, PTW1 can be divided into two categories: one category that overlaps with PTW2, and the other category that does not overlap with PTW2.

[0111] FIG. 2D The third line can be an example of a target PTW, that is, a target PTW can include all PTW2 as well as PTW1 that does not overlap with PTW2.

[0112] FIG. 2D The fourth line can be an example of a target PTW, namely, the target PTW is PTW1.

[0113] like FIG. 2E As shown, this disclosure provides a Radio Resource Management (RRM) measurement method, which is executed by a UE and includes:

[0114] S1410: In response to the target eDRX period being greater than or equal to a preset value, perform RRM measurement within the target PTW;

[0115] S1420: Determine the DRX period based on the RAN paging period, CN paging period, and / or the default paging period; wherein the RAN paging period is configured by the RAN and the CN paging period is configured by the CN;

[0116] S1430: Determine the measurement parameters for RRM measurement based on the DRX cycle.

[0117] The RAN paging cycle is configured by the RAN, for example, the RAN sends the RAN paging cycle to the UE through RRC signaling. The UE will listen to the RAN paging according to the RAN paging cycle within the first PTW.

[0118] The CN paging cycle can be configured by the CN. After the UE receives the CN paging cycle, the UE can listen to the CN paging according to the CN paging cycle within the second PTW.

[0119] The default paging cycle can be a paging cycle broadcast by a system message of the RAN. The paging cycle can be used to listen to the CN paging and / or the RAN paging.

[0120] In the embodiments of the present disclosure, the DRX cycle is determined according to the RAN paging cycle, the CN paging cycle and / or the default paging cycle. The DRX cycle can be used to determine the measurement parameter of the RRM measurement, for example, at least a period related to the RRM measurement is determined. The period related to the RRM measurement can include a detection period, a measurement period and / or an evaluation period.

[0121] That is, in the embodiments of the present disclosure, the DRX cycle is first determined, and then the measurement parameter of the RRM measurement in the target PTW is determined according to the DRX cycle.

[0122] It is worth noting that: the embodiment can be implemented alone, or can be combined with the foregoing embodiments, for example, combined with FIG. 2C the RRM measurement method shown in the figure, that is, the target PTW is determined according to FIG. 2C the method shown in the figure, and the measurement parameter of the RRM measurement is determined according to FIG. 2E the method shown in the figure.

[0123] In some embodiments, the DRX cycle is determined according to the RAN paging cycle, the CN paging cycle and / or the default paging cycle, including:

[0124] When the RRM measurement is performed in the target PTW, the DRX cycle is determined according to the first PTW and the second PTW, and the RAN paging cycle, the CN paging cycle and / or the default paging cycle.

[0125] In the embodiments of the present disclosure, the measurement parameter of the RRM measurement in different time ranges in the target PTW can be determined according to whether the current target PTW corresponds to the first PTW and the second PTW at the same time, if the current target PTW corresponds to the first PTW and the second PTW at the same time, the measurement parameter of the RRM measurement in different time ranges in the target PTW is determined according to the overlapping relationship of 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.

[0126] In some embodiments, when performing the 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, including at least one of:

[0127] for the RRM measurement in the first PTW without time domain overlap with the second PTW, the DRX cycle is determined according to the RAN paging cycle and the default paging cycle;

[0128] for the RRM measurement in the first PTW with time domain overlap with the second PTW, the DRX cycle is determined according to the RAN paging cycle, the CN paging cycle, and the default paging cycle;

[0129] for the time range of the second PTW except the first PTW with time domain overlap with the first PTW, the DRX cycle is determined according to the CN paging cycle and the default paging cycle.

[0130] In some embodiments, when the DRX cycle is determined according to 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 can be selected as the DRX cycle in combination with the time domain overlap between the first PTW and the second PTW. In this way, the measurement parameters of the RRM measurement are further determined according to this manner, which can further reduce the number of RRM measurements.

[0131] In other embodiments, when the DRX cycle is determined according to two or three of the RAN paging cycle, the default paging cycle, and the CN paging cycle, the smaller or the minimum of the two or three can be selected as the DRX cycle in combination with the time domain overlap between the first PTW and the second PTW. In this way, the measurement parameters of the RRM measurement are further determined according to this manner, which can better perform RRM measurement on the serving cell and / or the neighbor cell.

[0132] Exemplarily, the DRX cycle can be determined in multiple ways according to the time domain overlap between the first PTW and the second PTW, and the multiple ways are not in any particular order, and are described below for convenience of description and are numbered respectively:

[0133] Method one: for the RRM measurement in the first PTW without time domain overlap with the second PTW, the DRX cycle is determined as the minimum of the RAN paging cycle and the default paging cycle;

[0134] The second way: for the RRM measurement in the first PTW that has a time domain overlap with the second PTW, determining the DRX cycle as the minimum of the RAN paging cycle, the CN paging cycle and the default paging cycle;

[0135] The third way: for the time range in the second PTW that has a time domain overlap with the first PTW except the first PTW, determining the DRX cycle as the smaller one of the CN paging cycle and the default paging cycle.

[0136] Any two or three of the first way to the third way can be used in combination.

[0137] The first way of determining the DRX cycle in the embodiments of the present disclosure can be used for any one of the target PTW, for example, if the target PTW is the first PTW, the first way and the second way can be used to determine the DRX cycle related to the measurement parameter for the RRM measurement.

[0138] If the target PTW is the second PTW, the second way and the third way can be used in combination to determine the DRX cycle.

[0139] If the target PTW is the third PTW, or the second PTW and the first PTW that does not have a time domain overlap with the second PTW, the first way to the third way can be used to determine the DRX cycle in different target PTWs or the DRX cycle in different time ranges in the same target PTW. In this case, there can be multiple sets of measurement parameters for the RRM measurement in the target PTW, and different sets of measurement parameters involve different or all of the detection cycle, the measurement cycle and / or the evaluation cycle.

[0140] In some embodiments, the DRX cycle is determined according to the RAN paging cycle, the CN paging cycle and / or the default paging cycle, including at least one of:

[0141] The DRX cycle is determined according to the RAN paging cycle, the CN paging cycle and the default paging cycle;

[0142] The DRX cycle is determined according to the RAN paging cycle and the default paging cycle;

[0143] The DRX cycle is determined according to the CN paging cycle and the default paging cycle;

[0144] The RAN paging cycle, the CN paging cycle or the default paging cycle determines the DRX cycle.

[0145] In some embodiments, if the DRX cycle is determined according to 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 can be selected as the DRX cycle. In this way, the measurement parameters of the RRM measurement are further determined according to this manner, and the number of RRM measurements can be further reduced.

[0146] In some other embodiments, if the DRX cycle is determined according to two or three of the RAN paging cycle, the default paging cycle and the CN paging cycle, the smaller or the minimum of the two or three of the RAN paging cycle, the default paging cycle and the CN paging cycle can be selected as the DRX cycle. In this way, the measurement parameters of the RRM measurement are further determined according to this manner, and better RRM measurements of the serving cell and / or the neighbor cell can be performed.

[0147] Exemplarily, the DRX cycle is determined according to the RAN paging cycle, the CN paging cycle and / or the default paging cycle, including at least one of the following:

[0148] The DRX cycle is determined as the minimum of the RAN paging cycle, the CN paging cycle and the default paging cycle;

[0149] The DRX cycle is determined as the smaller of the RAN paging cycle and the default paging cycle;

[0150] The DRX cycle is determined as the smaller of the CN paging cycle and the default paging cycle;

[0151] The DRX cycle is determined as the RAN paging cycle, the CN paging cycle or the default paging cycle.

[0152] In the embodiments of the present disclosure, the DRX cycles of the measurement parameters of the RRM measurement in the target PTW are the same, i.e., the DRX cycles corresponding to the RRM measurement in different target PTWs or different time ranges of the same target PTW are all the same. In this way, the measurement parameters used by the RRM measurement in different target PTWs or in different time ranges of the same target PTW can all be the same, i.e., the detection period, the measurement period and the evaluation period are all the same.

[0153] In some embodiments, the preset value is 20.48s.

[0154] If the first eDRX cycle and / or the second eDRX cycle is greater than or equal to 20.48s, it means that the first eDRX cycle and / or the second eDRX cycle is configured with a PTW, and then the RRM measurement can be limited in the target PTW, so as to reduce unnecessary RRM measurement, save the power consumption caused by RRM measurement, and prolong the standby time of the UE.

[0155] In some embodiments, the network device (e.g. specifically the RAN) can configure the eDRX cycle for the UE in the inactive state to be greater than 10.24s. It can be understood that in some embodiments, the UE in the inactive state can receive the eDRX cycle in the inactive state and the eDRX cycle in the idle state.

[0156] The UE can perform the RRM measurement requirement under the eDRX mechanism based on any of the following methods.

[0157] Method 1: For the UE in the inactive state, the inactive eDRX cycle is configured, and the inactive eDRX cycle is greater than 10.24s, and the UE in the inactive state only performs the RRM measurement based on the received RAN paging cycle.

[0158] As an embodiment: the RRM measurement (serving cell and / or neighbor cell measurement) is limited in the PTW in which the RAN paging needs to be listened to, that is, the received CN paging cycle is ignored.

[0159] As an embodiment: the RRM measurement (serving cell and / or neighbor cell measurement) is limited in the PTW in the inactive state.

[0160] As an embodiment: the DRX cycle for the RRM measurement (serving cell and / or neighbor cell measurement) is the RAN paging cycle.

[0161]

[0162]

[0163]

[0164] It is worth noting that the contents of each row and column in the above table can be implemented individually, or can be implemented in any combination without conflict.

[0165] In the above table, the meaning of Nserv: similar to the role of a counter, if the UE evaluates the serving cell to not meet the S criterion in the last Nserv consecutive DRX cycles, the UE will start the measurement of all the neighbor cells indicated by the serving cell regardless of the current rule limiting the UE's measurement activity;

[0166] Tdetect: detection period;

[0167] Tmeasure: measurement period;

[0168] Tevaluate: evaluation period.

[0169] Mode 2: For the UE in Inactive mode, the UE is configured with an Inactive eDRX cycle larger than 10.24s. The Inactive eDRX cycle is configured with an Inactive PTW, denoted as PTW1. For the UE in idle mode, the UE is configured with an idle eDRX cycle. If the idle eDRX cycle is larger than 10.24s, the idle eDRX cycle is configured with an idle PTW, denoted as PTW2. It can be understood that in some embodiments, the UE in Inactive mode can receive the Inactive eDRX cycle and the idle eDRX cycle.

[0170] As an embodiment, for the scenario that the network device configures PTW1 and PTW2, the UE limits the RRM measurement within PTW1 and / or PTW2. The network device can include a RAN device (or access device) that configures PTW1. The network device can also include a CN device (for example, MME or AMF) that configures PTW2.

[0171] As an embodiment, for the scenario that the network configures PTW1 and PTW2, the UE limits the RRM measurement within a third PTW, wherein the third PTW is obtained based on the combination of the Inactive mode eDRX parameters and the idle mode eDRX parameters. For example, the period of the third PTW is determined based on the eDRX cycle provided by the Inactive mode eDRX parameters, and the window length of the third PTW is obtained based on the window length provided by the idle mode eDRX parameters.

[0172] As an embodiment, for the scenario that both PTW1 and PTW2 are configured for the UE by the network, the DRX cycle (T) for the UE to perform RRM measurement can be the cycle for the UE to monitor CN paging or the cycle for the UE to monitor RAN paging, or the cycle for the UE to monitor both CN paging and RAN paging.

[0173] When PTW1 and PTW2 conflict (there is overlap in time domain), the window of PTW2 is used as the boundary, in the range of overlap of PTW1 and PTW2, such as the length of PTW1 or PTW2, i.e. FIG. 2D The cross-line period, T = min{inactive DRX, idle DRX, default paging cycle}, and

[0174] Referring to FIG. 2D PTW1 and PTW2, in the PTW that only monitors CN paging. In the range of PTW2-PTW1, i.e. the remaining range of PTW2 except the part overlapping with PTW1, i.e. the right slant line part of the right of the cross period, T = min{idle DRX, default paging cycle}. Outside the range of PTW1 and PTW2, in the PTW1 that only monitors RAN paging (outside PTW2, the UE only performs measurement in PTW1, i.e. the left slant line part), T = min{inactive DXR}. When PTW1 and PTW2 conflict (there is overlap in time domain), the window of PTW1 is used as the boundary,

[0175] In PTW1 (the overlapping window), T = min{inactive mode DRX cycle, default paging cycle, idle mode DRX cycle, and outside the non-overlapping part of PTW1, the UE only performs measurement in PTW1, T = min{inactive DXR}.

[0176] The idle DRX is the aforementioned CN paging cycle. The inactive DXR is the aforementioned RAN paging cycle. The default paging cycle is the aforementioned default paging cycle.

[0177] The UE performs cell selection / reselection measurement of the UE in Inactive mode based on T obtained through the above judgment.

[0178]

[0179]

[0180]

[0181] It is worth noting that the contents of each row and / or column in the table above can be implemented individually or in any combination without conflict.

[0182] In the table above, Nserv means: similar to a counter. If the UE does not meet the S criterion when evaluating the serving cell within Nserv consecutive DRX cycles, then regardless of the current rules restricting the UE's measurement activities, the UE will initiate measurements of all neighboring cells indicated by the serving cell.

[0183] Tdetect: Detection period;

[0184] Tmeasure: Measurement period;

[0185] Tevaluate: Evaluation cycle.

[0186] It should be noted that when the UE performs RRM measurements, the measurements for the serving cell and neighboring cells can be based on the same measurement requirements. That is, the UE can use Method 1 to determine the measurement parameters for both the serving cell and neighboring cells, or Method 2 for both. Optionally, when the UE performs RRM measurements, the measurements for the serving cell and neighboring cells can also be based on different measurement requirements. For example, the UE can use Method 1 to determine the measurement parameters for the serving cell and Method 2 for the neighboring cells. Alternatively, the UE can use Method 2 to determine the measurement parameters for the serving cell and Method 1 for the neighboring cells. Or, the UE can use either Method 1 or Method 2 to determine the measurement parameters for the serving cell and other methods for the neighboring cells. Or, the UE can use either Method 1 or Method 2 to determine the measurement parameters for the neighboring cells and other methods for the serving cell.
