Description

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. In particular, it relates to a method and apparatus for determining radio resource management (RRM) measurement configuration, a communication device, and a storage medium. Background Art

[0002] Due to the mobility of the user equipment (UE), the UE needs to perform RRM measurements to facilitate selecting a suitable cell for residence based on the measurement results, so as to obtain wireless communication services.

[0003] When performing RRM measurements, it is determined according to the RRM measurement configuration.

[0004] In some cases, considering that the mobility rate of the UE slows down or the sleep time of the UE becomes longer, the RRM measurement can be relaxed. When relaxing the RRM measurement, usually the measurement period is enlarged or the number of sampling points for a single measurement is reduced, etc. Summary of the Invention

[0005] Embodiments of the present disclosure provide a method and apparatus for terminal control, a method and apparatus for information processing, a communication device, and a storage medium.

[0006] In a first aspect of the embodiments of the present disclosure, a method for determining radio resource management (RRM) measurement configuration is provided, which is executed by a user equipment (UE). The method includes:

[0007] In response to the extended discontinuous reception (eDRX) cycle of the UE having a paging time window (PTW), according to the situation of the RRM measurement relaxation being restricted by the PTW, determine the relaxed RRM measurement configuration.

[0008] In a second aspect of the embodiments of the present disclosure, a device for determining radio resource management (RRM) measurement configuration is provided. The device includes:

[0009] A first determination module, configured to, in response to the eDRX cycle of the UE having a paging time window (PTW), determine the relaxed RRM measurement configuration according to the situation of the RRM measurement relaxation being restricted by the PTW.

[0010] In a third aspect of the embodiments of the present disclosure, a communication device is provided, including a processor, a transceiver, a memory, and an executable program stored on the memory and capable of running on the processor. Wherein, when the processor runs the executable program, it executes the RRM measurement configuration determination method as described in the foregoing first aspect.

[0011] A fourth aspect of an embodiment of the present disclosure provides a computer storage medium, wherein the computer storage medium stores an executable program; after the executable program is executed by a processor, the RRM measurement configuration determination method provided in the first aspect can be implemented.

[0012] According to the technical solution provided by the embodiment of the present disclosure, if the UE is configured with an eDRX cycle, after entering the eDRX cycle, if it is necessary to relax the RRM measurement, the measurement configuration of the relaxed RRM measurement can be determined by combining the eDRX cycle and the various RRM measurement-associated cycles after the relaxation, and whether it is limited to the paging time window (PTW) of the eDRX cycle. The relaxed RRM measurement configuration determined according to the eDRX cycle of the UE and the PTW of the eDRX cycle is adapted to the eDRX cycle in which the UE is currently located, so that on the one hand, the relaxation of the RRM measurement can be achieved, thereby reducing the power consumption of the RRM measurement, and on the other hand, the measurement configuration of the relaxed RRM measurement is adapted to the eDRX cycle and PTW of the UE to reduce unnecessary wake-ups caused by the RRM measurement as much as possible, thereby further reducing the power consumption caused by unnecessary wake-ups and extending the standby time of the UE as much as possible.

[0028] Please refer to Figure 1 , which shows a schematic structural diagram of a wireless communication system provided by the embodiments of the present disclosure. As Figure 1As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: a plurality of UEs 11 and a plurality of access devices 12.

[0029] Among them, the UE 11 may be a device that provides voice and / or data connectivity to users. The UE 11 may communicate with one or more core networks via a Radio Access Network (RAN). The UE 11 may be an Internet of Things (IoT) UE, such as a sensor device, a mobile phone (or called a "cellular" phone), and a computer with an IoT UE. For example, it may be a fixed, portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted device. 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). Or, the UE 11 may also be a device of an unmanned aerial vehicle. Or, the UE 11 may also be a vehicle-mounted device. For example, it may be an on-board computer with wireless communication functions, or a wireless communication device external to the on-board computer. Or, the UE 11 may also be a roadside device. For example, it may be a street lamp, a traffic signal, or other roadside devices with wireless communication functions.

[0030] The access device 12 may be a network-side device in the wireless communication system. Among them, the wireless communication system may be a fourth-generation mobile communication technology (4G) system, also known as the Long Term Evolution (LTE) system; or, the wireless communication system may also be a 5G system, also known as the new radio (NR) system or 5G NR system. Or, the wireless communication system may also be the next generation system after the 5G system. Among them, the access network in the 5G system may be called the NG-RAN (New Generation - Radio Access Network, new generation wireless access network). Or, an MTC system.

[0031] Among them, the access device 12 may be an evolved access device (eNB) adopted in a 4G system. Alternatively, the access device 12 may also be an access device (gNB) with a centralized distributed architecture adopted in a 5G system. When the access device 12 adopts a centralized distributed architecture, it generally includes a central unit (CU) and at least two distributed units (DUs). The protocol stacks of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer are set in the central unit; the Physical (PHY) layer protocol stack is set in the distributed unit. The specific implementation manner of the access device 12 in the embodiments of the present disclosure is not limited.

[0032] A wireless connection may be established between the access device 12 and the UE 11 through a wireless air interface. In different embodiments, 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, such as the new air interface; or, the wireless air interface may also be a wireless air interface based on the standard of the next-generation mobile communication network technology of 5G.

[0033] In some embodiments, an E2E (End to End) connection may also be established between UEs 11. For example, scenarios such as vehicle-to-vehicle (V2V) communication, vehicle-to-infrastructure (V2I) communication, and vehicle-to-pedestrian (V2P) communication in vehicle-to-everything (V2X) communication.

[0034] In some embodiments, the above wireless communication system may further include a network management device 13.

[0035] A plurality of access devices 12 are respectively connected to a network management device 13. Among them, the network management device 13 may be a core network device in a wireless communication system. For example, the network management device 13 may be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, the network management device may also be other core network devices, such as a Serving GateWay (SGW), a Public Data Network GateWay (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS), etc. The implementation form of the network management device 13 is not limited in the embodiments of the present disclosure.

[0036] If the UE activates the eDRX function, it will enter the eDRX mode. The UE in the eDRX mode has the following characteristics:

[0037] The UE is reachable at any time, but the reachability delay is relatively large, and the delay depends on the eDRX cycle configuration.

[0038] In this way, the UE that activates the eDRX function maximally achieves a balance between the power consumption of the UE and the timeliness of data transmission.

[0039] The eDRX function has one or more of the following eDRX parameters:

[0040] The starting time domain position of the PTW;

[0041] The length of the PTW;

[0042] The eDRX cycle, which can be represented by T eDRX，H denote.

[0043] Figure 2 The figure shows a timing diagram after the UE activates the eDRX function.

[0044] Refer to Figure 2 It can be known that: there is a PTW within an eDRX cycle; there is one or more DRX cycles within the PTW.

[0045] The duration of the DRX cycle can be much smaller than the duration of the eDRX cycle. Exemplarily, when the eDRX cycle is greater than 10.24 s, the eDRX cycle can be as Figure 2 shown, including a PTW composed of one or more DRX cycles.

[0046] Figure 3 Shown is one of the eDRX parameters for the interaction of the eDRX function between the UE (i.e., the UE) and the core network.

[0047] Figure 3 The method for the UE and the core network to interact with eDRX parameters may include:

[0048] The eNB sends an indication of the allowed eDRX function, a cell-specific DRX, and a hyper system frame number (SFN) to the UE through a system information block (SIB).

[0049] When the UE sends an attach request or a tracking area update (TAU) TAU request, it sends UE-specific DRX parameters and / or preferable eDRX parameters;

[0050] After receiving the above attach request or TAU request, the MME sends an eDRX configuration to the UE; the eDRX configuration carries one or more of the foregoing eDRX parameters;

[0051] The MME performs paging according to the eDRX configuration;

[0052] After receiving the CN paging message sent by the MME, the eNB forwards the CN paging message to the UE.

[0053] The eDRX parameters sent by the core network are transparently transmitted to the UE through a base station (e.g., an evolved base station (eNB) or a next-generation base station (gNB)). For example, the mobile management entity (MME) of the core network sends the eDRX parameters of the eDRX function to the UE through the eNB.

[0054] The RRC idle state, abbreviated as the idle state; is a low-power state of the UE known to the core network.

[0055] The RRC inactive state, abbreviated as the inactive state. The inactive state is a low-power state of the UE that is transparent to the core network. However, the inactive state is visible to the access network.

[0056] If the UE enters the inactive state, the UE needs to receive the paging message sent by the CN (i.e., the CN paging message), and also needs to receive the paging message sent by the radio access network (RAN), i.e., the RAN paging message.

[0057] As Figure 4 shown, an embodiment of the present disclosure provides a method for determining an RRM measurement configuration, which is executed by a UE. The method includes:

[0058] S110: In response to the eDRX cycle of the UE having a paging time window (PTW), determine a relaxed RRM measurement configuration according to the situation of relaxing the RRM measurement for the PTW.

[0059] The UE has different states. For example, the UE has a connected state (also known as the RRC connected state) or a non-connected state, and the non-connected state includes, but is not limited to: an idle state (also known as the RRC idle state) and / or an inactive state (also known as the RRC inactive state).

[0060] In some cases, the UE has an idle state eDRX cycle, and in other cases, the UE has an inactive state eDRX cycle. In some cases, the UE has both an idle state eDRX cycle and an inactive state eDRX cycle.

[0061] The idle state eDRX cycle can be: the eDRX cycle applied when the UE is listening for core network paging messages. The inactive state eDRX cycle can be: the eDRX cycle applied for listening for RAN paging when the UE is in the inactive state.

[0062] In some embodiments, the eDRX cycle of the UE involved in S110 is the cycle used to determine the RRM measurement configuration, and can be determined according to the current state of the UE and the eDRX cycle configuration. Exemplarily, the eDRX cycle of the UE used to determine the RRM measurement configuration can be as follows:

[0063] If the UE is in the idle state and the UE is not configured with an idle state eDRX cycle, it is determined that the UE does not have an eDRX cycle for determining the RRM measurement, and then the RRM measurement configuration is determined according to the DRX cycle of the UE. Here, the RRM measurement configuration includes: the RRM measurement configuration before relaxation and / or the RRM measurement configuration after relaxation;

[0064] If the UE is in the idle state and the UE is configured with an idle state eDRX cycle, it is determined that the UE has an eDRX cycle for determining the RRM measurement, and the eDRX cycle of the UE used to determine the RRM measurement can be equal to the idle state eDRX cycle;

[0065] If the UE is in the inactive state, and the UE is not configured with an idle eDRX cycle and is not configured with an inactive eDRX cycle, it is determined that the UE does not have an eDRX cycle for determining RRM measurements, then the RRM measurement configuration is determined according to the DRX cycle of the UE, where the RRM measurement configuration includes: the RRM measurement configuration before relaxation and / or the RRM measurement configuration after relaxation;

[0066] If the UE is in the inactive state, and the UE is configured with an idle eDRX cycle and is not configured with an inactive eDRX cycle, it is determined that the UE does not have an eDRX cycle for determining RRM measurements, then the RRM measurement configuration is determined according to the DRX cycle of the UE, where the RRM measurement configuration includes: the RRM measurement configuration before relaxation and / or the RRM measurement configuration after relaxation;

[0067] If the UE is in the inactive state, and the UE is configured with an idle eDRX cycle and is not configured with an inactive eDRX cycle, it is determined that the UE has an eDRX cycle for determining RRM measurements, and the eDRX cycle used by the UE to determine RRM measurements is equal to the idle eDRX cycle;

[0068] If the UE is in the inactive state, and the UE is configured with an idle eDRX cycle and is not configured with an inactive eDRX cycle, it is determined that the UE has an eDRX cycle for determining RRM measurements, and the eDRX cycle used by the UE to determine RRM measurements is equal to the inactive eDRX cycle;

[0069] If the UE is in the inactive state, and the UE is configured with an idle eDRX cycle and is not configured with an inactive eDRX cycle, it is determined that the UE has an eDRX cycle for determining RRM measurements, and the eDRX cycle used by the UE to determine RRM measurements is equal to the smaller of the idle eDRX cycle and the inactive eDRX cycle.

[0070] If the eDRX cycle is greater than a preset cycle, such an eDRX cycle has a PTW; if the eDRX cycle is not greater than the preset cycle, such an eDRX cycle may not have a PTW.

[0071] Exemplarily, for example, an eDRX cycle greater than 10.24 s may have a PTW, while an eDRX cycle less than or equal to 10.24 s may not have a PTW. One or more DRX cycles are set within the PTW.

[0072] In one embodiment, that the eDRX cycle of the UE has a PTW means that the eDRX cycle used by the UE to determine RRM measurements has a PTW, that is, when the eDRX cycle used by the UE to determine RRM measurements is greater than a preset cycle, it is determined that the eDRX cycle used by the UE to determine RRM measurements has a PTW.

[0073] When the eDRX cycle used by the UE to determine RRM measurements is greater than a preset cycle, that is, it is determined that the eDRX cycle has a PTW, and then the duration of the PTW can be determined by at least one of the following methods:

[0074] If the UE is in the idle state, and the eDRX cycle used by the UE to determine RRM measurements is the idle-state eDRX cycle, and the idle-state eDRX cycle has a PTW, then the PTW of the eDRX cycle used by the UE to determine RRM measurement configuration is equal to the PTW of the idle-state eDRX cycle;

[0075] If the UE is in the inactive state, the eDRX cycle used to determine RRM measurements is the inactive-state eDRX cycle, and the inactive-state eDRX cycle has a PTW, then the PTW of the eDRX cycle used by the UE to determine RRM measurement configuration is equal to the PTW of the inactive-state eDRX cycle;

[0076] If the UE is in the inactive state, the eDRX cycle used by the UE to determine RRM measurements is the idle-state eDRX cycle, and the idle-state eDRX cycle of the UE has a PTW, then the eDRX cycle used by the UE to determine RRM measurement configuration has a PTW, and the PTW of the eDRX cycle used by the UE to determine RRM measurement configuration is equal to: the PTW of the idle-state eDRX cycle; here the UE may or may not have an inactive-state eDRX cycle;

[0077] If the UE is in the inactive state, the eDRX cycle used by the UE to determine RRM measurements is the inactive-state eDRX cycle, and the idle-state eDRX cycle of the UE has a PTW while the inactive-state eDRX cycle does not have a PTW, then the eDRX cycle used by the UE to determine RRM measurement configuration does not have a PTW;

[0078] If the UE is in the inactive state, the UE has an idle-state eDRX cycle and a non-idle-state eDRX cycle, and the eDRX cycle used by the UE to determine RRM measurements can be: the larger or smaller of the idle-state eDRX cycle and the non-idle-state eDRX cycle. Further determine whether the eDRX cycle used for the RRM policy has a PTW. If the eDRX cycle used for the RRM policy has a PTW, the PTW can be: one of the PTW of the idle-state eDRX cycle and the PTW of the non-idle-state eDRX.

[0079] Exemplarily, if both the idle-state eDRX period and the non-idle-state eDRX period of the UE have a PTW, then the PTW for determining the RRM measurement at this time can be the larger or the smaller of the PTWs of the idle-state eDRX period and the non-idle-state eDRX period. Also exemplarily, the eDRX period used by the UE to determine the RRM measurement can be: the smaller of the idle-state eDRX period and the non-idle-state eDRX period, and the PTW for determining the RRM measurement can be the PTW of the larger of the idle-state eDRX period and the non-idle-state eDRX period. If only one of the idle-state eDRX period and the inactive-state eDRX period has a PTW, then this PTW can be the PTW for determining the RRM measurement.

[0080] When specifically determining the RRM measurement before relaxation and / or the RRM measurement after relaxation, it is necessary to determine according to the DRX period. And the determination of the DRX period used to determine the RRM measurement can adopt one of the following methods:

[0081] If the eDRX period used to determine the RRM measurement is the idle-state eDRX period, and the idle-state eDRX period has a PTW, then the DRX period used by the UE to determine the RRM measurement configuration can be the idle-state DRX period within the PTW of the idle-state eDRX period;

[0082] If the eDRX period used to determine the RRM measurement is the inactive-state eDRX period, and the inactive-state eDRX period has a PTW, then the DRX period used by the UE to determine the RRM measurement configuration can be the radio access network (RAN) paging period within the PTW of the inactive-state eDRX period;

[0083] If the eDRX period used to determine the RRM measurement is the inactive-state eDRX period, and the inactive-state eDRX period has a PTW, then the DRX period used by the UE to determine the RRM measurement configuration can be: the smaller of the radio access network (RAN) paging period and the idle-state DRX period within the PTW of the inactive-state eDRX period;

[0084] If the eDRX period used to determine the RRM measurement is the inactive-state eDRX period, and the inactive-state eDRX period has a PTW, then the DRX period used by the UE to determine the RRM measurement configuration can be: the minimum of the radio access network (RAN) paging period, the idle-state DRX period, and the default paging period within the PTW of the inactive-state eDRX period;

[0085] If the eDRX period used to determine the RRM measurement is the inactive-state eDRX period, and the inactive-state eDRX period has a PTW, then the DRX period used by the UE to determine the RRM measurement configuration can be: the smaller of the radio access network (RAN) paging period and the default paging period within the PTW of the inactive-state eDRX period.

[0086] If the UE is currently in the idle state and performs periodic sleep and wake-up according to the idle state eDRX cycle, then at this time, the RRM measurement configuration after RRM measurement relaxation can be determined according to the idle state eDRX cycle of the UE and the PTW within the idle state eDRX cycle.

[0087] Based on the state of the UE and different eDRX configurations, the eDRX cycle, the paging time window PTW, and the DRX cycle can be obtained in the following manner:

[0088] As an embodiment, the duration of the DRX cycle for determining the RRM measurement configuration before and after relaxation is equal to: min{idle state DRX cycle, default paging cycle};

[0089] If the UE is currently in the inactive state and only the idle state eDRX cycle is configured, then as an embodiment, the RRM measurement configuration before and after relaxation is determined according to the idle state eDRX cycle of the UE and the PTW within the idle state eDRX cycle (i.e., the idle state PTW).

[0090] As an embodiment, the duration of the DRX cycle for determining the RRM measurement configuration before and after relaxation is equal to: min{idle state DRX cycle, default paging cycle} or min{idle state DRX cycle, default paging cycle, RAN paging cycle}.

[0091] If the UE is currently in the inactive state and both the idle state eDRX cycle and the inactive state eDRX cycle are configured:

[0092] As an embodiment, if periodic sleep and wake-up are performed according to the inactive state eDRX cycle, then at this time, the RRM measurement configuration after RRM measurement relaxation can be determined according to the inactive state eDRX cycle of the UE and the PTW within the inactive state eDRX cycle (i.e., the inactive state PTW window length).

[0093] As an embodiment, the duration of the DRX cycle for determining the RRM measurement configuration before and after relaxation is equal to: min{idle state DRX cycle, default paging cycle, RAN paging cycle},

[0094] or min{default paging cycle, RAN paging cycle}

[0095] or the RAN paging cycle.

[0096] As an embodiment, periodic sleep and wake-up are performed according to the idle eDRX cycle. At this time, the RRM measurement configurations before and after relaxation can be determined according to the idle eDRX cycle of the UE and the PTW (i.e., the idle PTW window length) within the idle eDRX cycle.

[0097] As an embodiment, the duration of the DRX cycle used to determine the RRM measurement configuration is equal to min{idle DRX cycle, default paging duration} or min{idle DRX cycle, default paging duration, RAN paging cycle}

[0098] As an embodiment, periodic sleep and wake-up are performed according to min{idle eDRX cycle, inactive eDRX cycle}. At this time, the RRM measurement configurations before and after measurement relaxation can be determined according to min{idle eDRX cycle, inactive eDRX cycle} of the UE and max{idle PTW window length, inactive PTW window length} or min{idle PTW window length, inactive PTW window length}.

[0099] As an embodiment, the duration of the DRX cycle used to determine the RRM measurement configuration is equal to: min{idle DRX cycle, default paging duration, RAN paging cycle}.

[0100] In one embodiment, the RRM measurement configuration includes: the RRM measurement configuration for the serving cell and / or the RRM measurement configuration for the neighboring cells. Therefore, the relaxed RRM measurement configuration can also include: the relaxed RRM measurement configuration for the serving cell and / or the relaxed RRM measurement configuration for the neighboring cells.

[0101] When the state of the UE meets the relaxation measurement condition, the RRM measurement will be relaxed. After determining that the RRM measurement is relaxed, the RRM measurement will be performed according to the relaxed RRM measurement configuration.

[0102] In one embodiment, the state of the UE meeting the relaxation measurement condition includes but is not limited to at least one of the following:

[0103] The UE is currently in the central area of the serving cell;

[0104] The change amount of the reference signal value of the serving cell currently measured by the UE is less than the change amount threshold;

[0105] The current moving speed of the UE is less than the speed threshold.

[0106] Exemplarily, the state of the UE meeting the relaxation measurement condition includes but is not limited to at least one of the following:

[0107] The UE is in the non-connected state and is currently in the central area of the serving cell;

[0108] The UE is in the idle state and the current moving speed of the UE is less than the speed threshold.

[0109] The geographical area corresponding to the cell may include: a central area and an edge area. The distance between the central area and the base station is less than the distance between the edge area and the base station. The edge area can also be called the cell edge. Usually, the edge area of the cell is the area adjacent to other cells, while the central area of the cell is far from the cell edge and is an area with a relatively large distance from neighboring cells.

[0110] Since the UE is in the central area of the serving cell, the probability that the UE needs to perform cell reselection based on RRM measurements is relatively low. Therefore, the RRM measurements can be appropriately relaxed.

[0111] Since the moving speed of the UE is less than the speed threshold, it indicates that the UE is in a stationary state or a low-speed moving state. Then the probability that the UE moves out of the current cell is very low, and the RRM measurements can also be appropriately relaxed.

[0112] The moving speed of the UE can be determined according to the speed detected by the UE's own speed sensor, or can also be determined according to the change amount of the reference signal value of the serving cell currently detected by the UE.

[0113] If the change amount of the signal measurement value of the serving cell by the UE currently is very small, it indicates that the UE may currently be in a stationary or low-speed moving state. Then the probability that the UE moves out of the current cell is very low, and the RRM measurements can also be appropriately relaxed.

[0114] Exemplarily, the RRM measurement configuration includes at least one of the following:

[0115] The RRM measurement configuration for the serving cell, where the RRM measurement configuration for the serving cell at least includes a measurement period; the measurement period is used for measuring the serving cell;

[0116] The RRM measurement configuration for neighboring cells, where the RRM measurement configuration for neighboring cells includes at least one of: a detection period, a measurement period, and an evaluation period;

[0117] The detection period is used to identify and evaluate neighboring cells;

[0118] The measurement period is used for measuring neighboring cells;

[0119] The evaluation period is used to evaluate neighboring cells according to the measurement results obtained by the measurement period.

[0120] The serving cell can be the cell where the UE currently camps. For the serving cell, the UE can directly perform measurements.

[0121] For neighboring cells, the UE needs to detect the neighboring cells to identify them, then measure the identified neighboring cells based on the measurement period, and evaluate the neighboring cells after completing the measurement of the neighboring cells.

[0122] Therefore, the measurement configuration for RRM measurement of neighboring cells includes at least one of: detection period, measurement period, and evaluation period.

[0123] The neighboring cells include but are not limited to: co-frequency neighboring cells, different-frequency neighboring cells, and / or different-system neighboring cells.

[0124] 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 cells to obtain measurement results. The reference signal includes but is not limited to:

[0125] Synchronization Signal and PBCH block (SSB), where PBCH is the abbreviation of Physical Broadcast Channel;

[0126] Channel Status Information Reference Signal (CSI-RS).

[0127] The measurement results may include but are not limited to:

[0128] Measured signal value;

[0129] Comparison result between the measured signal value and the corresponding threshold.

[0130] The measured signal value includes but is not limited to Reference Signal Received Power (RSRP) or Reference Signal Received Quality (RSRQ). When performing RRM measurement relaxation, measurement of the serving cell can be relaxed, and / or at least one of detection, measurement, and evaluation of the neighboring cells can be relaxed.

[0131] Relaxing RRM measurement can expand various periods in RRM measurement and / or reduce the number of measurement points in a single measurement, etc. In the embodiments of the present disclosure, in order to simplify the processing, relaxation of measurement can be achieved by one of the ways of expanding various periods in RRM measurement.

[0132] Exemplarily, the S110 may include at least one of the following:

[0133] Relax the PTW according to the relaxation limitation of the RRM measurement, and expand any period included in the RRM measurement configuration before relaxation by a relaxation coefficient to obtain a period after relaxation, where the relaxation coefficient is any positive integer greater than 1.

[0134] The situation where the RRM measurement relaxation is limited by the PTW may include at least one of the following two situations: the relaxation is limited by the PTW and / or the RRM measurement relaxation is not limited by the PTW.

[0135] When the RRM measurement relaxation is not limited by the PTW, the periods included in any RRM measurement configuration after relaxation can be arbitrarily relaxed based on the relaxation coefficient.

[0136] When the RRM measurement relaxation is limited by the PTW, it is necessary to adjust the relaxation coefficient so that the period included in the RRM measurement configuration after relaxation does not exceed the duration of the PTW.

[0137] In the embodiments of the present disclosure, the relaxation coefficient can be any positive integer greater than 1.

[0138] In one embodiment, the period after relaxation may include at least one of the following:

[0139] For the serving cell and the measurement period after relaxation, the measurement period after relaxation is longer than the measurement period before relaxation. Therefore, the measurement interval between two adjacent measurements for the serving cell increases;

[0140] For the neighboring cell and the detection period after relaxation, the detection period after relaxation is larger than the detection period before relaxation. Thus, the time interval between two adjacent detections increases, thereby reducing the detection frequency;

[0141] For the neighboring cell and the measurement period after relaxation, the measurement period after relaxation is larger than the measurement period before relaxation. Thus, the time interval between two adjacent measurements increases, thereby reducing the measurement frequency;

[0142] For the neighboring cell and the evaluation period after relaxation, the evaluation period after relaxation is larger than the evaluation period before relaxation. Thus, the time interval between two adjacent evaluations increases, thereby reducing the evaluation frequency.

[0143] Exemplarily, the situation where the RRM measurement relaxation is limited by the PTW includes that the RRM measurement relaxation is limited by the PTW and / or the RRM measurement relaxation is not limited by the PTW. The determination of various periods associated with the RRM measurement after relaxation in these two situations can be at least one of the following:

[0144] In response to the relaxation of RRM measurement not being limited by the PTW, the amplified period associated with the RRM measurement can be greater than the PTW of the eDRX period, that is, the duration corresponding to the amplified period associated with the RRM measurement in response to the relaxation not being limited by the PTW can be distributed within one or more PTWs;

[0145] In response to the relaxation being limited by the PTW, the amplified period associated with the RRM measurement cannot be greater than the PTW of the eDRX period, that is, the duration corresponding to the amplified period associated with the RRM measurement in response to the RRM measurement relaxation being limited by the PTW will only be distributed within one PTW.

[0146] In one embodiment, determining the relaxed RRM measurement configuration according to the situation of the relaxation of the RRM measurement being limited by the PTW includes at least one of the following:

[0147] In response to the relaxation of RRM measurement not being limited by the PTW, determine the relaxed measurement period for the serving cell according to the relaxation coefficient;

[0148] In response to the relaxation of RRM measurement not being limited by the PTW, determine at least one of the detection period, measurement period, and evaluation period for neighboring cells according to the relaxation coefficient;

[0149] In response to the relaxation being limited by the PTW, determine the relaxed measurement period for the serving cell according to the relaxation coefficient and the duration of the PTW;

[0150] In response to the relaxation being limited by the PTW, determine at least the relaxed measurement period and / or evaluation period for neighboring cells according to the relaxation coefficient and the duration of the PTW;

[0151] In response to the relaxation being limited by the PTW, determine the relaxed detection period for neighboring cells according to the relaxation coefficient.

[0152] It should be noted that: in the embodiments of the present disclosure, regardless of whether the relaxation is limited by the PTW of the UE, the detection period for neighboring cells can ignore the PTW and directly determine it according to the relaxation coefficient. Thus, regardless of whether the relaxation is limited by the PTW of the UE, the detection period for neighboring cells is related to the relaxation coefficient and has nothing to do with the PTW. At this time, the detection period for neighboring cells can be distributed within one PTW or multiple PTWs.

[0153] For the serving cell, if the relaxation is not limited by the PTW, only determine the relaxed measurement period according to the relaxation coefficient. If the relaxation is limited by the PTW, it is necessary to combine the relaxation coefficient and the PTW to determine the measurement period of the serving cell.

[0154] For neighboring cells, if the relaxation is not restricted by PTW, the measurement period and / or evaluation period after relaxation for neighboring cells need to be determined according to the relaxation coefficient. If the relaxation is restricted by PTW, the measurement period and / or evaluation period for neighboring cells need to be determined by combining the relaxation coefficient and PTW.

[0155] The following respectively exemplify the cases where RRM measurement relaxation is not restricted by the PTW and relaxation is restricted by PTW, and illustrate each period before and after the RRM measurement configuration relaxation. In specific implementation, it may not be limited to the following examples:

[0156] For the detection period of neighboring cells, regardless of whether the relaxation is restricted by PTW, the detection period after relaxation can be directly determined according to the current relaxation coefficient. Therefore, in response to determining the detection period after relaxation for neighboring cells according to the relaxation coefficient, the detection period before relaxation is:

[0157] In response to determining the detection period after relaxation for neighboring cells according to the relaxation coefficient, the detection period after relaxation is:

[0201] Determine the relaxed measurement period for the serving cell according to the relaxation coefficient. The relaxed measurement period is:

[0218] In the above embodiments, if the relaxed detection period, evaluation period, and / or measurement period are determined according to the relaxation coefficient and the PTW, and it is found that the period determined solely according to the relaxation coefficient exceeds the length of the PTW, then the relaxation coefficient is reduced or a new relaxation coefficient is selected, at least such that the duration of the relaxed detection period, evaluation period, and / or measurement period determined by the re-determined relaxation coefficient does not exceed the PTW.

[0219] Exemplarily, the S110 may include at least one of the following:

[0220] In response to the RRM measurement relaxation not being limited by the PTW, determining a relaxed measurement period for the serving cell according to the relaxation coefficient, where the number of DRX cycles included in the relaxed measurement period for the serving cell is allowed to be greater than the number of DRX cycles included in one PTW;

[0221] In response to the RRM measurement relaxation not being limited by the PTW, determining at least one of the detection period, measurement period, and evaluation period for a neighboring cell according to the relaxation coefficient, where the number of discontinuous reception DRX cycles included in the relaxed detection period, measurement period, and evaluation period is allowed to be greater than the number of DRX cycles included in one PTW;

[0222] In response to the relaxation being limited by the PTW, determining a relaxed measurement period for the serving cell according to the relaxation coefficient and the duration of the PTW, where the number of DRX cycles included in the relaxed measurement period for the serving cell is not greater than the number of DRX cycles included in one PTW;

[0223] In response to the relaxation being limited by the PTW, determining at least the relaxed measurement period and / or evaluation period for a neighboring cell according to the relaxation coefficient and the duration of the PTW; where the number of DRX cycles included in the relaxed measurement period and evaluation period is not greater than the number of discontinuous reception DRX cycles included in one PTW;

[0224] In response to the relaxation being limited by the PTW, determining a relaxed detection period for a neighboring cell according to the relaxation coefficient.

[0225] In some embodiments, for the relaxation of RRM measurements for neighboring cells, when determining the relaxed RRM measurement configuration, only one of the detection period, measurement period, and evaluation period can be relaxed. Therefore, the response to RRM measurement relaxation is not limited by the PTW. Determining at least one of the relaxed detection period, measurement period, and evaluation period for neighboring cells according to the relaxation coefficient includes at least one of the following:

[0226] The response to RRM measurement relaxation is not limited by the PTW, and the relaxed detection period for neighboring cells is determined according to the relaxation coefficient of the detection period for neighboring cells;

[0227] The response to RRM measurement relaxation is not limited by the PTW, and the relaxed measurement period for neighboring cells is determined according to the coefficient of the measurement period for neighboring cells;

[0228] The response to RRM measurement relaxation is not limited by the PTW, and the relaxed evaluation period for neighboring cells is determined according to the relaxation coefficient of the evaluation period for neighboring cells;

[0229] Any two of the relaxation coefficients of the detection period, measurement period, and evaluation period for neighboring cells are independent of each other.

[0230] The so-called independence here means that the relaxation coefficients of the detection period, measurement period, and evaluation period for neighboring cells can be set independently. Therefore, the relaxation coefficients of the detection period, measurement period, and evaluation period for neighboring cells can be equal or unequal.

[0231] In some embodiments, the specific relaxation coefficient can be determined according to the eDRX period corresponding to the current state of the UE and the DRX periods included in the PTW of the eDRX period.

[0232] Exemplarily, the relaxed RRM measurement configuration for the serving cell can be determined with reference to Table 1 or Table 2:

[0233]

[0234]

[0235] Table 1

[0236] It should be noted that any element in Table 1 can be used alone or in combination with other elements.

[0237] Among them, K4 is the relaxation coefficient for the serving cell.

[0238]

[0239] Table 2

[0240] It should be noted that any element in Table 2 can be used alone or in combination with other elements.

[0241] M9 to M12 in Table 2 are the relaxation coefficients for the measurement period of the serving cell, and they are all less than

[0242] Comparing Table 1 and Table 2, it can be seen that in Table 1, regardless of the duration of the eDRX period and the DRX period of the current UE, a unified relaxation coefficient K4 can be adopted. However, if the duration of the eDRX period and / or the DRX period of the UE in Table 1 is different, the adopted relaxation coefficients may be different.

[0243] Table 1 and Table 2 are only examples of the relaxed RRM measurement configuration for the serving cell, and the specific implementation is not limited thereto.

[0244] Exemplarily, the relaxed RRC measurement configuration for the neighboring cell can be determined according to Table 3.

[0245]

[0246]

[0247] Table 3

[0248] It should be noted that any element in Table 3 can be used alone or in combination with other elements.

[0249] T in Table 3 detect refers to the detection period for the neighboring cell; T measure refers to the measurement period for the neighboring cell; T evaluate refers to the evaluation period for the neighboring cell.

[0250] M1 to M9 in the table are the relaxation coefficients, and they are all less than If the period of the relaxed RRM measurement is determined according to Table 3, obviously, if the UE has different eDRX periods and DRX periods, the corresponding relaxation coefficients are different.

[0251] In one embodiment, as Figure 5 shown, the method further includes:

[0252] S100: Determine whether to allow relaxation of RRM measurement when the UE has the eDRX period;

[0253] The S110 may include: S111; the S111 may include: determining a relaxed RRM measurement configuration according to the situation where the RRM measurement relaxation is restricted by the PTW in response to allowing the relaxation of RRM measurement when the UE has the eDRX cycle and the eDRX cycle of the UE has the PTW.

[0254] In some cases, if the UE is in the idle state and switches between the sleep and wake states according to the eDRX cycle, even if the relaxation condition of the RRM measurement is met, if the relaxation of the RRM measurement is not allowed, the RRM measurement can continue according to the original measurement configuration of the RRM measurement. If the relaxation configuration of the RRM measurement allows the RRM measurement, it is necessary to determine the measurement configuration of the relaxed RRM measurement and perform the RRM measurement according to the relaxed RRM measurement configuration.

[0255] Whether the UE allows the RRM measurement method can be indicated by the network side or determined by the UE itself.

[0256] For example, the network side device (e.g., base station and / or core network device) or the UE itself can determine whether to allow the UE to relax the RRM measurement according to the type of the UE, the service type of the UE, and / or the priority of the UE, etc. If most of the service types of the UE are high-priority service types, or the type of the UE indicates that the UE is a high-mobility UE, if the RRM measurement is relaxed, it may cause a large delay for the UE to camp on the cell and / or a large delay or low quality in obtaining the corresponding service, and this large delay or low quality will result in a poor user experience for the UE, then the relaxation of the RRM measurement may be prohibited, otherwise the relaxation of the RRM measurement can be allowed.

[0257] In the embodiments of the present disclosure, the S110 is executed to obtain the relaxed RRM measurement configuration only when it is determined that the UE allows the relaxation of the measurement.

[0258] In some embodiments, the S100 may include at least one of the following:

[0259] Determining whether to allow the relaxation of the RRM measurement when the UE has the eDRX cycle according to the protocol;

[0260] Determining whether to allow the relaxation of the RRM measurement when the UE has the eDRX cycle according to the received configuration signaling.

[0261] For example, the protocol stipulates whether to allow the relaxation of the RRM measurement when the UE has the eDRX cycle, or the protocol stipulates whether to allow the relaxation of the RRM measurement when the UE has the eDRX cycle according to the UE type or the service type involved by the UE. If it is stipulated by the protocol, both the UE and the network device can query according to the protocol to know whether the relaxation of the RRM measurement is allowed currently.

[0262] In some cases, network devices (e.g., base stations and / or core network devices) may send configuration signaling indicating whether to allow a UE to perform RRM measurements.

[0263] This configuration signaling may be RRC signaling, MAC layer signaling, or DCI.

[0264] For example, if the configuration signaling is RRC signaling, it may correspond to one or more bits sent together with the measurement configuration signaling before RRM measurement relaxation.

[0265] If the configuration signaling is physical layer DCI, it has the characteristic of strong dynamics. The network side can dynamically indicate whether to allow the UE to relax its RRM measurements with low latency according to the current network conditions and / or UE conditions.

[0266] The eDRX mechanism for idle state UEs and the eDRX mechanism for non-active users have been introduced, but there are no relevant regulations for RRM measurement relaxation of UEs under the eDRX mechanism.

[0267] Introduce a new method for RRM measurement relaxation of co-frequency / hetero-frequency / hetero-system neighboring cells for UEs with eDRX.

[0268] When a UE is configured with an eDRX period and the corresponding PTW, if the RRM measurement relaxation condition is met, the following parameters can be relaxed using an extended period method:

[0269] Tdetect: Detection period;

[0270] Tmeasure: Measurement period;

[0271] Tevaluate: Evaluation period.

[0272] Tdetect, Tmeasure, Tevaluate: At least one of them will be extended, and the durations corresponding to the extended Tdetect, Tmeasure, Tevaluate can only be distributed within one PTW.

[0273] In one embodiment, at least one of Tdetect, Tmeasure, Tevaluate will be extended, and the extended Tdetect, Tmeasure, Tevaluate may cross PTWs, that is, the durations corresponding to the extended Tdetect, Tmeasure, Tevaluate can be distributed in different PTWs.

[0274] As one embodiment:

[0275] After expansion, Tdetect still spans the PTW: When expanding Tdetect, it can be done by multiplying the Tdetect before expansion by K1;

[0276]

[0277] Or

[0278]

[0279] After expansion, Tmeasure spans the PTW: When expanding Tmeasure, it can be done by multiplying the Tmeasure before expansion by K2;

[0280]

[0281] Or

[0282]

[0283] After expansion, Tevaluate spans the PTW: When expanding Tevaluate, it can be done by multiplying the Tevaluate before expansion by K3;

[0284]

[0285] Or

[0286]

[0287] It should be noted that: The aforementioned K1, K2, and K3 may be the same or may be different, and they are all relaxation coefficients.

[0288] After expanding at least one of Tmeasure and Tevaluate by a certain multiple, it may not span the PTW, that is, the value of the expansion multiple is restricted not to exceed the number of DRXs within the configured PTW, as shown in Table 3 above. The relaxation coefficients M1, M2, M3, M4, M5, M6, M7, and M8 can be equal or not equal. PTW is the duration of the UE's PTW; and DRX_cycle_length is the duration of the DRX cycle within the PTW.

[0289] As an example:

[0290] Only expand Tmeasure, and after expanding Tmeasure by a certain multiple, it does not span the PTW. The relaxation coefficient (or called expansion coefficient) corresponding to this expansion multiple can be agreed upon by the protocol. That is, the values of M5, M6, M7, and M8 in Table 3 above are not less than 1.

[0291] As an example:

[0292] Only expand Tevaluate, and after the expansion multiple of Tevaluate, it does not cross PTW (protocol - agreed expansion coefficient, and the expanded period does not exceed PTW), that is, the values of M1 / M2 / M3 / M4 in the above table are not less than 1.

[0293] As an embodiment:

[0294] Both Tmeasure or Tevaluate are expanded by a multiple, and after the expansion, they do not cross PTW (protocol - agreed expansion coefficient, and the expanded periods do not exceed PTW), that is, the coefficients M1, M2, M3, M4, M5, M6, M7, and M8 in the above table are all greater than 1 and less than a number, and any two of M1, M2, M3, M4, M5, M6, M7, and M8 can be equal or unequal.

[0295] When PTW is used for RRM measurement, it is based on network configuration or pre - agreed protocol whether measurement relaxation can be performed under eDRX configuration.

[0296] As an embodiment: The network sets a switch, and this switch indicates whether to allow or not to allow relaxation of RRM measurement when there is an eDRX period.

[0297] A method for determining the configuration of service cell measurement relaxation for UEs with eDRX periods is introduced. For example, when the expansion multiple K4 of Nserv may cross PTW, the measurement period after relaxation for the service cell can refer to Table 1 above.

[0298] When the expansion multiple of Nserv may not cross PTW, that is, the value of the expansion multiple is restricted not to exceed the number of DRX within the configured PTW, the measurement period after relaxation for the service cell can refer to Table 2.

[0299] Among them, the coefficients M9 to M12 are all less than and any two of M9 to M12 can be equal or unequal.

[0300] As Figure 6 shown, an embodiment of the present disclosure provides a method, and this method may include:

[0301] S210: Receive a configuration signaling, where the configuration signaling is used for the UE to determine whether to allow relaxation of RRM measurement when there is an eDRX period.

[0304] This method is executed by a network device, which can be any other device located on the network side, such as a base station.
