Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to an RRM measurement relaxation indication method, apparatus, user equipment, base station, and storage medium. Background Technology

[0002] In communication systems, when a UE meets measurement relaxation criteria (such as low mobility criteria, not at cell edge criteria, and stationary criteria), the UE's measurement state is determined to be a measurement relaxation state in order to reduce UE power consumption.

[0003] In related technologies, when a non-connected UE in a measurement relaxation state enters a connected state, the base station cannot know the UE's behavior in the non-connected state. The base station will first configure measurement configuration information for normal measurement to the UE through RRC (Radio Resource Control) messages. After that, the UE will re-determine whether it meets the measurement relaxation criteria. If it does, it will report to the base station and receive the relaxation measurement configuration information configured by the base station to determine the UE's measurement state as a measurement relaxation state.

[0004] In other words, in the relevant technology, every time a UE in the measurement relaxation state enters the connected state, it needs to perform a second RRC configuration to determine the UE's measurement state as the measurement relaxation state. In addition, during this second RRC configuration process, the UE also needs to perform unnecessary measurements and report additional RRM measurement relaxation indications, which results in redundancy in signaling interaction and measurement process. Summary of the Invention

[0005] The RRM measurement relaxation indication method, apparatus, user equipment, base station, and storage medium disclosed herein aim to solve the technical problem of redundancy in signaling interaction and measurement process when a UE in a non-connected state and in a measurement relaxation state enters a connected state.

[0006] This disclosure discloses an RRM measurement relaxation indication method, applied to a UE, comprising:

[0007] The UE switches from a non-connected state to a connected state, and sends a status indication message to the base station when the UE is in a measurement relaxation state before switching to the connected state;

[0008] Obtain at least one of relaxation instruction information and relaxation measurement configuration information from the base station;

[0009] The measurement status of the UE is determined based on at least one of the relaxation instruction information and the relaxation measurement configuration information.

[0010] The RRM measurement relaxation indication method proposed in another embodiment of this disclosure, applied to a base station, includes:

[0011] Receive status indication information from the UE;

[0012] Send at least one of relaxation instruction information and relaxation measurement configuration information to the UE.

[0013] Another embodiment of this disclosure provides an RRM measurement relaxation indicator device, comprising:

[0014] The sending module is used to switch from a non-connected state to a connected state, and when the UE is in a measurement relaxation state before the measurement state is connected, it sends a status indication information to the base station.

[0015] The acquisition module is used to acquire at least one of relaxation instruction information and relaxation measurement configuration information from the base station;

[0016] The determination module is used to determine the measurement status of the UE based on at least one of the relaxation instruction information and the relaxation measurement configuration information.

[0017] Another embodiment of this disclosure provides an RRM measurement relaxation indicator device, comprising:

[0018] The receiving module is used to receive status indication information sent by the UE;

[0019] The transmitting module is used to transmit at least one of relaxation instruction information and relaxation measurement configuration information to the UE.

[0020] Another aspect of this disclosure provides a user equipment comprising: a transceiver; a memory; and a processor, respectively connected to the transceiver and the memory, configured to control the transmission and reception of wireless signals of the transceiver by executing computer-executable instructions on the memory, and capable of implementing the method proposed in the preceding aspect of the embodiment.

[0021] Another aspect of this disclosure provides a base station, comprising: a transceiver; a memory; and a processor, respectively connected to the transceiver and the memory, configured to control the transmission and reception of wireless signals of the transceiver by executing computer-executable instructions on the memory, and capable of implementing the method proposed in the other aspect of the above disclosure.

[0022] In another aspect of this disclosure, a computer storage medium is provided, wherein the computer storage medium stores computer-executable instructions; the computer-executable instructions, when executed by a processor, can implement the method described above.

[0023] In summary, in the RRM measurement relaxation indication method, apparatus, user equipment, base station, and storage medium provided in this disclosure, when a UE switches from a non-connected state to a connected state, and is in a measurement relaxation state before switching to the connected state, it sends status indication information to the base station, and then obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station. Based on at least one of the relaxation indication information and relaxation measurement configuration information, the UE's measurement state is determined. Therefore, in this disclosure, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it sends status indication information to the base station and obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station based on the status indication information. This allows the UE to directly enter the measurement relaxation state when its measurement state is connected, based on at least one of the relaxation indication information and relaxation measurement configuration information. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in a non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

[0054] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the embodiments of this disclosure as detailed in the appended claims.

[0055] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. The singular forms “a” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0056] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of embodiments of this disclosure, and similarly, second information may also be referred to as first information. Depending on the context, the words “if” and “suppose” as used herein may be interpreted as “when”, “when”, or “in response to a determination”.

[0057] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0058] In the RRM measurement relaxation indication method provided in this embodiment, when a UE switches from a non-connected state to a connected state, and is in a measurement relaxation state before switching to the connected state, it sends status indication information to the base station, and then obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station. Based on at least one of the relaxation indication information and relaxation measurement configuration information, the UE's measurement state is determined. Therefore, in this embodiment, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it sends status indication information to the base station and obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station based on the status indication information. This allows the UE to directly enter the measurement relaxation state when its measurement state is connected, based on at least one of the relaxation indication information and relaxation measurement configuration information. In other words, only one RRC configuration is needed for a connected UE to inherit the measurement relaxation state of a non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in a non-connected state enters a connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

[0059] The RRM measurement relaxation indication method, apparatus, user equipment, base station, and storage medium provided in this disclosure are described in detail below with reference to the accompanying drawings.

[0060] Figure 1 This is a flowchart illustrating an RRM measurement relaxation indication method provided in an embodiment of this disclosure, applied to a UE, such as... Figure 1 As shown, the RRM measurement relaxation indication method may include the following steps:

[0061] Step 101: Switch from non-connected state to connected state, and when the UE is in measurement relaxation state before switching to connected state, send status indication information to the base station.

[0062] It should be noted that the indication method of this disclosure can be applied to any UE. The UE can be a device that provides voice and / or data connectivity to a user. The UE can communicate with one or more core networks via a RAN (Radio Access Network). The UE can be an IoT terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, or user agent. Alternatively, the UE can also be a device of an unmanned aerial vehicle. Alternatively, the UE can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless terminal connected to an external vehicle computer. Alternatively, the UE can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0063] In one embodiment of this disclosure, status indication information can be used to indicate that the UE meets the measurement relaxation criteria before switching to the connected state.

[0064] In one embodiment of this disclosure, the non-connected state can be an idle state or an inactive state.

[0065] Furthermore, in one embodiment of this disclosure, the method for the UE to send status indication information to the base station may include: sending status indication information to the base station via RRC messages during the RRC (Radio Resource Control) connection establishment / restore process.

[0066] Specifically, in one embodiment of this disclosure, when the UE switches from an idle state to a connected state, and is in a measurement relaxation state before switching to the connected state, it sends status indication information to the base station via an RRC message during the RRC connection establishment process. In another embodiment of this disclosure, when the UE switches from an inactive state to a connected state, and is in a measurement relaxation state before switching to the connected state, it sends status indication information to the base station via an RRC message during the RRC connection recovery process.

[0067] Step 102: Obtain at least one of relaxation instruction information and relaxation measurement configuration information from the base station.

[0068] In one embodiment of this disclosure, the aforementioned relaxation indication information is specifically used to indicate that the measurement state of the connected UE is allowed to be in a measurement relaxation state. The relaxation measurement configuration information is specifically used to perform relaxation measurement.

[0069] Furthermore, in one embodiment of this disclosure, the UE only obtains the relaxation instruction information sent by the base station. In another embodiment of this disclosure, the UE only obtains the relaxation measurement configuration information sent by the base station. In yet another embodiment of this disclosure, the UE obtains both the relaxation instruction information and the relaxation measurement configuration information sent by the base station.

[0070] Step 103: Determine the measurement status of the UE based on at least one of the relaxation instruction information and the relaxation measurement configuration information.

[0071] In one embodiment of this disclosure, the aforementioned normal measurement state and measurement relaxation state are both used to measure RRM (Radio Resource Management), and primarily to measure the RRM of neighboring cells.

[0072] In summary, in the RRM measurement relaxation indication method provided in this disclosure, when a UE switches from a non-connected state to a connected state, and is in a measurement relaxation state before switching to the connected state, it sends status indication information to the base station, and then obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station. Based on at least one of the relaxation indication information and relaxation measurement configuration information, the UE's measurement state is determined. Therefore, in this disclosure embodiment, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it sends status indication information to the base station and obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station based on the status indication information. This allows the UE to directly enter the measurement relaxation state when its measurement state is connected, based on at least one of the relaxation indication information and relaxation measurement configuration information. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in a non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

[0073] Figure 2 This is a flowchart illustrating another embodiment of the RRM measurement relaxation indication method provided in this disclosure, applied to a UE, such as... Figure 2 As shown, the RRM measurement relaxation indication method may include the following steps:

[0074] Step 201: When the UE is in a disconnected state, determine whether the UE meets the relaxation criteria.

[0075] In one embodiment of this disclosure, the relaxation criteria may include at least one of the following: low mobility criterion, not at cell edge criterion, and stationary criterion.

[0076] Furthermore, in one embodiment of this disclosure, the method for determining whether a connected UE meets the low mobility criterion may include: determining a preset reference value of the received signal strength of the current serving cell within a first preset time period. (Unit: dB) and the actual received signal strength S of the UE in the current serving cell. rxlev Is the absolute value of the difference (in dB) less than the first preset threshold value S? searchDeltaP During the first preset time period, Always less than S searchDeltaP If the signal amplitude of the UE changes little, it can be approximated that the UE is in a low-mobility state, thus determining that the UE meets the low-mobility criterion. Otherwise, it is determined that the UE does not meet the low-mobility criterion.

[0077] Furthermore, in one embodiment of this disclosure, the method for determining whether a connected UE satisfies the criterion of not being at the cell edge may include: determining whether the UE is in the current serving cell's S rxlev Is it greater than the second preset threshold value S? searchThresholdP And, determine the actual received signal quality S of the UE in the current serving cell. qual Is it greater than the third preset threshold value S? searchThresholdQ When S rxlev >S searchThresholdP And S qual >S searchThresholdQ If the condition is met, the UE is considered not to be at the cell edge, and the UE is determined to meet the non-cell edge criterion; otherwise, the UE is determined not to meet the non-cell edge criterion.

[0078] Furthermore, in one embodiment of this disclosure, the method for determining whether a connected UE satisfies the static criterion may include: determining whether the connected UE corresponds to a static criterion within a second preset time period. Whether it is less than the fourth preset threshold, and whether the number of beam switching times of the UE is less than the fifth preset threshold, if within the second preset time period, If the signal amplitude of the UE is always less than the fourth threshold and the number of beam switching is less than the fifth threshold, then it is considered that the UE signal amplitude changes little and the number of beam switching is small. In other words, the UE can be approximately considered to be in a stationary state, and thus it can be determined that the UE meets the stationary criterion; otherwise, it is determined that the UE does not meet the stationary criterion.

[0079] It should be noted that, in one embodiment of this disclosure, the aforementioned first preset time period, second preset time period, and first to fifth preset thresholds can be provided by the base station, and the aforementioned judgment criteria (e.g., by judging...) Is it less than S? searchDeltaP The determination of whether a UE meets the low mobility criteria can be agreed upon by the protocol.

[0080] Furthermore, in one embodiment of this disclosure, the first preset time period and the second preset time period may be the same or different; and the first preset threshold value and the fourth preset threshold value may be the same or different.

[0081] Furthermore, it should be noted that in one embodiment of this disclosure, if the UE satisfies any one of the relaxation criteria, the connected UE is considered to satisfy the relaxation criteria. Also, in one embodiment of this disclosure, if the UE satisfies any pairwise combination of the relaxation criteria or all three of the above criteria, the connected UE is considered to satisfy the relaxation criteria.

[0082] Furthermore, if the UE meets the relaxation criteria, the UE's measurement state is determined to be in a relaxed state, and step 202 is executed. Otherwise, the UE's measurement state is determined to be in a normal measurement state.

[0083] Step 202: Switch from non-connected state to connected state and send status indication information to the base station.

[0084] In one embodiment of this disclosure, the state indication information can be used to indicate that the UE meets the measurement relaxation criteria before switching to the connected state. In another embodiment of this disclosure, the state indication information can be used to indicate the specific relaxation criteria that the UE meets before switching to the connected state, such as meeting the low mobility criterion, the not being at the cell edge criterion, or the stationary criterion, etc.

[0085] Step 203: Obtain at least one of relaxation instruction information and relaxation measurement configuration information from the base station.

[0086] Step 204: Determine the measurement status of the UE based on at least one of the relaxation instruction information and the relaxation measurement configuration information.

[0087] For a detailed description of steps 202 to 204, please refer to the relevant descriptions in the above embodiments. This disclosure will not repeat them here.

[0088] In summary, in the RRM measurement relaxation indication method provided in this disclosure, when a UE switches from a non-connected state to a connected state, and is in a measurement relaxation state before switching to the connected state, it sends status indication information to the base station, and then obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station. Based on at least one of the relaxation indication information and relaxation measurement configuration information, the UE's measurement state is determined. Therefore, in this disclosure embodiment, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it sends status indication information to the base station and obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station based on the status indication information. This allows the UE to directly enter the measurement relaxation state when its measurement state is connected, based on at least one of the relaxation indication information and relaxation measurement configuration information. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in a non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

[0089] Figure 3 This is a flowchart illustrating an RRM measurement relaxation indication method provided in another embodiment of the present disclosure, applied to a UE, such as... Figure 3 As shown, the RRM measurement relaxation indication method may include the following steps:

[0090] Step 301: When the UE is in an idle state, determine whether the UE meets the relaxation criteria.

[0091] In one embodiment of this disclosure, the relaxation criteria may include at least one of the following: low mobility criterion, not at cell edge criterion, and stationary criterion.

[0092] Furthermore, for a detailed description of the method for determining whether the UE meets the relaxation criteria, please refer to the relevant descriptions in the above embodiments. This disclosure will not elaborate further here.

[0093] Furthermore, if the UE meets the relaxation criteria, the UE's measurement state is determined to be in a relaxed state, and step 302 is executed. Otherwise, the UE's measurement state is determined to be in a normal measurement state.

[0094] Step 302: Switch from idle state to connected state and send status indication information to the base station.

[0095] In one embodiment of this disclosure, the method for sending status indication information to the base station when the UE switches from idle state to connected state may include any of the following:

[0096] The first method involves sending status indication information to the base station via an RRC Setup Request message.

[0097] The second method involves sending status indication information to the base station via a newly established RRC Setup Request 1 message.

[0098] The third method involves sending a status indication message to the base station via an RRC Setup Complete message.

[0099] Step 303: Obtain relaxation measurement configuration information from the base station.

[0100] In one embodiment of this disclosure, when the UE sends status indication information to the base station through any of the methods in step 302 above, the method for the UE to obtain the relaxation measurement configuration information sent by the base station may include: obtaining the relaxation measurement configuration information sent by the base station through the RRC Reconfiguration message.

[0101] Furthermore, in one embodiment of this disclosure, the relaxation measurement configuration information may include at least one of the following:

[0102] Delete the measurement configuration information under normal measurement conditions;

[0103] The number of new measurement frequencies is less than the number of measurement frequencies under normal measurement conditions.

[0104] The new SMTC (Synchronization Signal Block Measurement Timing Configuration) has a longer period than the SMTC under normal measurement conditions.

[0105] The new SMTC has a smaller window length than the SMTC under normal measurement conditions.

[0106] The new SSB-ToMeasure (Synchronization Signal Block-ToMeasure) parameters have a smaller number of measurement beams than the SSB-ToMeasure parameters under normal measurement conditions.

[0107] The new pilot signals that need to be measured are fewer in number than the pilot signals under normal measurement conditions.

[0108] In one embodiment of this disclosure, the relaxation measurement configuration information may be any one of the above configuration information. In another embodiment of this disclosure, the relaxation measurement configuration information may be any pairwise combination, any three-way combination, any four-way combination, any five-way combination, or all six types of the above configuration information.

[0109] Furthermore, it should be noted that in one embodiment of this disclosure, the UE obtains a new set of relaxation measurement configuration information sent by the base station. Therefore, when the UE performs measurement relaxation based on the relaxation measurement configuration information, it can directly perform measurement relaxation according to the received relaxation measurement configuration information.

[0110] Step 304: Perform measurement relaxation based on the relaxed measurement configuration information to determine the measurement state of the connected UE as the measurement relaxation state.

[0111] In one embodiment of this disclosure, the measurement relaxation operation performed is different when the content included in the relaxation measurement configuration information is different.

[0112] Specifically, in one embodiment of this disclosure, when the relaxed measurement configuration information includes deleting the measurement configuration information under the normal measurement state, the method for the UE to perform measurement relaxation based on the relaxed measurement configuration information may specifically include: deleting the measurement configuration information under the normal measurement state to stop the measurement of RRM. For example, in one embodiment of this disclosure, the UE can stop the measurement of RRM by deleting all measurement identifiers in the measurement configuration information under the normal measurement state. It should also be noted that, in one embodiment of this disclosure, when the relaxed measurement configuration information includes deleting the measurement configuration information under the normal measurement state, after the base station sends the relaxed measurement configuration information, within a preset time period, the base station can send the original measurement configuration information under the normal measurement state (i.e., the original configuration) to the UE via an RRC message (e.g., an RRC reconfiguration message) to ensure that the connected UE can successfully switch back to the normal measurement state based on the original configuration. The preset time period may be, for example, 24 hours.

[0113] Furthermore, in another embodiment of this disclosure, when the relaxed measurement configuration information includes a new measurement frequency, the method for the UE to perform measurement relaxation based on the relaxed measurement configuration information may specifically include: performing measurement relaxation only on measurement identifiers that include the new measurement frequency, wherein each measurement identifier is simultaneously connected to a measurement object and a reporting configuration, and the UE can perform the corresponding measurement based on the measurement object and reporting configuration matched by the measurement identifier.

[0114] For example, in one embodiment of this disclosure, assuming the new measurement frequency is 3 GHz (megahertz), then the UE

[0115] It allows for measurement of signals only in the 3GHz band, while omitting measurements of signals in other bands, thus enabling relaxed measurement.

[0116] Furthermore, in another embodiment of this disclosure, when the relaxation measurement configuration information includes a new SMTC cycle, the method for the UE to perform measurement relaxation based on the relaxation measurement configuration information may specifically include: directly using the new SMTC cycle to perform measurement relaxation.

[0117] For example, in one embodiment of this disclosure, assuming the period of SMTC under normal measurement conditions is 5ms, the period of the new SMTC can be 20ms, and the UE can perform measurement relaxation based on the new SMTC period of 20ms.

[0118] In another embodiment of this disclosure, when the relaxation measurement configuration information includes a new SMTC window length, the method for the UE to perform measurement relaxation based on the relaxation measurement configuration information may specifically include: directly performing measurement relaxation using the new SMTC window length.

[0119] For example, in one embodiment of this disclosure, assuming the window length of SMTC under normal measurement conditions is 5ms, the window length of the new SMTC can be 3ms, and the UE can perform measurement relaxation based on the new SMTC window length of 3ms.

[0120] In another embodiment of this disclosure, when the relaxation measurement configuration information includes a new SSB-ToMeasure parameter, the method for the UE to perform measurement relaxation based on the relaxation measurement configuration information may specifically include: directly using the new SSB-ToMeasure parameter to perform measurement relaxation.

[0121] For example, in one embodiment of this disclosure, assuming that the number of measurement beams corresponding to the SSB-ToMeasure parameter under normal measurement conditions is 32, the number of measurement beams corresponding to the new SSB-ToMeasure parameter can be 8, and the UE can perform measurement relaxation based on the new SSB-ToMeasure parameter 8.

[0122] In another embodiment of this disclosure, when the relaxation measurement configuration information includes a new pilot signal that needs to be measured, the method for the UE to perform measurement relaxation based on the relaxation measurement configuration information may specifically include: performing measurement relaxation directly based on the new pilot signal that needs to be measured.

[0123] For example, in one embodiment of this disclosure, assuming that the pilot signals to be measured under normal measurement conditions are SSB and CSI-RS, the new pilot signal to be measured may be only SSB. The UE may only perform measurement on the pilot signal SSB and only report the measurement result for SSB.

[0124] Furthermore, it should be noted that in one embodiment of this disclosure, when the idle-state UE meets different relaxation criteria, the content included in the corresponding relaxation measurement configuration information can be the same.

[0125] In another embodiment of this disclosure, the content included in the corresponding relaxation measurement configuration information may differ when the idle-state UE meets different relaxation criteria. Furthermore, in one embodiment of this disclosure, when the content included in the relaxation measurement configuration information for UEs under different relaxation criteria differs, the relaxation degree of the relaxation measurement configuration information for UEs meeting the stationary criterion may be greater than the relaxation degree of the relaxation measurement configuration information for UEs meeting the low mobility criterion and greater than the relaxation degree of the relaxation measurement configuration information for UEs meeting the not-at-cell-edge criterion.

[0126] For example, in one embodiment of this disclosure, the relaxed measurement configuration information for a UE that meets the stationary criterion may include: deleting the measurement configuration information under normal measurement conditions; the relaxed measurement configuration information for a UE that meets the low mobility criterion may include: a measurement period expansion factor; and the relaxed measurement configuration information for a UE that meets the not-at-cell-edge criterion may include: a dedicated measurement frequency.

[0127] In summary, in the RRM measurement relaxation indication method provided in this disclosure, when a UE switches from a non-connected state to a connected state, and is in a measurement relaxation state before switching to the connected state, it sends status indication information to the base station, and then obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station. Based on at least one of the relaxation indication information and relaxation measurement configuration information, the UE's measurement state is determined. Therefore, in this disclosure embodiment, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it sends status indication information to the base station and obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station based on the status indication information. This allows the UE to directly enter the measurement relaxation state when its measurement state is connected, based on at least one of the relaxation indication information and relaxation measurement configuration information. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in a non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

[0128] Figure 4 This is a flowchart illustrating an RRM measurement relaxation indication method provided in yet another embodiment of this disclosure, applied to a UE, such as... Figure 4 As shown, the RRM measurement relaxation indication method may include the following steps:

[0129] Step 401: When the UE is in an idle state, determine whether the UE meets the relaxation criteria.

[0130] In one embodiment of this disclosure, the relaxation criteria may include at least one of the following: low mobility criterion, not at cell edge criterion, and stationary criterion.

[0131] Furthermore, if the UE meets the relaxation criteria, the UE's measurement state is determined to be in a relaxed state, and step 402 is executed. Otherwise, the UE's measurement state is determined to be in a normal measurement state.

[0132] Step 402: Switch from idle state to connected state and send status indication information to the base station.

[0133] In one embodiment of this disclosure, the method for the UE to send status indication information to the base station when switching from idle state to connected state may include the following:

[0134] The first method involves sending status indication information to the base station via an RRC Setup Request message.

[0135] The second method involves sending status indication information to the base station via a newly established RRC Setup Request 1 message.

[0136] The third method involves sending a status indication message to the base station via an RRC Setup Complete message.

[0137] Step 403: Obtain relaxation indication information from the base station. The relaxation indication information is used to indicate that the measurement status of the UE is in a measurement relaxation state.

[0138] In one embodiment of this disclosure, when the UE sends status indication information to the base station through any of the methods in step 402 above, the method for the UE to obtain the relaxation indication information sent by the base station may include: obtaining the relaxation indication information sent by the base station through the RRCReconfiguration message.

[0139] Furthermore, in another embodiment of this disclosure, when the UE sends status indication information to the base station through the first or second method in step 402 above, the method for the UE to obtain the relaxation indication information sent by the base station may include: obtaining the relaxation indication information sent by the base station through the RRC Setup (connection establishment) message.

[0140] Step 404: Obtain the measurement configuration information of the normal measurement status sent by the base station.

[0141] In one embodiment of this disclosure, the method for a UE to obtain measurement configuration information of normal measurement status sent by a base station may include: obtaining measurement configuration information of normal measurement status sent by the base station through an RRC Reconfiguration message.

[0142] Step 405: Obtain the predefined measurement relaxation parameters indicated by the base station.

[0143] In one embodiment of this disclosure, the method for the UE to obtain predefined measurement relaxation parameters indicated by the base station may include at least one of the following:

[0144] The first method involves obtaining predefined measurement relaxation parameters sent by the base station via system messages. For example, in one embodiment of this disclosure, predefined measurement relaxation parameters can be obtained by the base station broadcasting them via SIB (System Information Block) X, where X can be any SIB.

[0145] The second method involves obtaining predefined measurement relaxation parameters indicated by the base station based on a protocol. For example, in one embodiment of this disclosure, predefined measurement relaxation parameters indicated by the base station based on the TS38.331 protocol can be obtained.

[0146] The third method involves obtaining predefined measurement relaxation parameters sent by the base station via RRC messages. For example, in one embodiment of this disclosure, predefined measurement relaxation parameters sent by the base station to the UE via RRC Reconfiguration or RRC Set Up messages can be obtained.

[0147] Fourth, obtain the predefined measurement relaxation parameters carried in the relaxation instruction information.

[0148] Specifically, in one embodiment of this disclosure, the UE can obtain predefined measurement relaxation parameters using only the first, second, third, or fourth method described above. In another embodiment of this disclosure, the method by which the UE obtains the predefined measurement relaxation parameters indicated by the base station can also be any pairwise combination, any triadic combination, or all four of the above methods.

[0149] In one embodiment of this disclosure, the predefined measurement relaxation parameter may specifically include at least one of the following:

[0150] Predefined measurement period expansion factor;

[0151] The number of predefined measurement frequencies is less than the number of measurement frequencies in normal measurement conditions.

[0152] The predefined SMTC has a period longer than the SMTC period under normal measurement conditions.

[0153] The predefined SMTC has a smaller window length than the SMTC in normal measurement conditions.

[0154] The number of measurement beams corresponding to the predefined SSB-ToMeasure parameters is less than the number of measurement beams corresponding to the SSB-ToMeasure parameters under normal measurement conditions.

[0155] The predefined pilot signals to be measured are fewer in number than those in the normal measurement state.

[0156] In one embodiment of this disclosure, the relaxation parameter can be any one of the above parameters. In another embodiment of this disclosure, the relaxation parameter can be any pairwise combination, any three-three combination, any four-four combination, any five-five combination, any six-six combination, or all seven of the above parameters.

[0157] Step 406: Perform measurement relaxation based on predefined measurement relaxation parameters and measurement configuration information of normal measurement state to determine the measurement state of the connected UE as the measurement relaxation state.

[0158] In one embodiment of this disclosure, when the UE performs measurement relaxation based on predefined measurement relaxation parameters and measurement configuration information of the normal measurement state, the UE replaces the corresponding measurement relaxation parameters in the measurement configuration information of the normal measurement state with the predefined measurement relaxation parameters. It should be noted that the specific operation of performing measurement relaxation based on the predefined measurement relaxation parameters and measurement configuration information of the normal measurement state will differ depending on the content included in the measurement relaxation parameters.

[0159] Specifically, in one embodiment of this disclosure, when the predefined measurement relaxation parameters include a predefined measurement period expansion factor, the method for the UE to perform measurement relaxation based on the predefined measurement relaxation parameters and the measurement configuration information of the normal measurement state may specifically include: determining the measurement period in the relaxed measurement state as the product of the predefined measurement period expansion factor and the measurement period in the normal measurement state, and performing relaxation measurement based on the measurement period in the relaxed measurement state. In one embodiment of this disclosure, the expansion factor may specifically be a natural number greater than 1.

[0160] Furthermore, it should be noted that in one embodiment of this disclosure, the measurement period under normal measurement conditions is calculated by the UE based on a formula. Specifically, without DRX (Discontinuous Reception) and measurement gap (time interval) configured, the measurement period under normal measurement conditions = max(200ms, 5 × SMTC period). In one embodiment of this disclosure, the SMTC period can be carried in the measurement configuration information configured by the base station to the UE for use under normal measurement conditions. In another embodiment of this disclosure, the UE can also calculate the measurement period under normal measurement conditions based on the DRX period and MGRP (Measuring Gap Repetition Period).

[0161] Furthermore, in one embodiment of this disclosure, when the UE performs a measurement based on a measurement cycle, it can obtain a measurement result in one measurement cycle, wherein the measurement result is specifically obtained through the evaluation of multiple measurement sample points (i.e., multiple SMTCs).

[0162] Furthermore, in another embodiment of this disclosure, when the predefined measurement relaxation parameters include a predefined measurement frequency, the method for the UE to perform measurement relaxation based on the predefined measurement relaxation parameters and the measurement configuration information of the normal measurement state may specifically include: the UE only performs measurement for measurement identifiers that include predefined measurement frequencies, wherein each measurement identifier is simultaneously connected to a measurement object and a reporting configuration, and the UE can perform the corresponding measurement based on the measurement object and reporting configuration matched by the measurement identifier.

[0163] For example, in one embodiment of this disclosure, it is assumed that the predefined measurement frequency is 3 GHz (megahertz). Then the UE can only measure the measurement identifier that includes the 3 GHz band, and not measure the measurement identifier that includes other frequency bands, thereby achieving relaxed measurement.

[0164] Furthermore, in another embodiment of this disclosure, when the predefined measurement relaxation parameters include a predefined SMTC, the method for the UE to perform measurement relaxation based on the predefined measurement relaxation parameters and the measurement configuration information of the normal measurement state may specifically include: replacing the SMTC in the measurement configuration information of the normal measurement state with the predefined SMTC.

[0165] For example, in one embodiment of this disclosure, it is assumed that the period of SMTC under normal measurement conditions is 5ms, and the predefined period of SMTC is 20ms. Then, when the UE performs measurement relaxation based on the predefined SMTC, the UE performs RRM measurement according to the predefined SMTC period of 20ms.

[0166] In another embodiment of this disclosure, when the predefined measurement relaxation parameters include a predefined SMTC, the method for the UE to perform measurement relaxation based on the predefined measurement relaxation parameters and the measurement configuration information of the normal measurement state may specifically include: replacing the SMTC in the measurement configuration information of the normal measurement state with the predefined SMTC.

[0167] For example, in one embodiment of this disclosure, assuming the window length of SMTC in normal measurement state is 5ms and the predefined window length of SMTC is 3ms, then when the UE performs measurement relaxation based on the predefined SMTC, the UE performs RRM measurement according to the predefined SMTC window length of 3ms.

[0168] In another embodiment of this disclosure, when the predefined measurement relaxation parameters include a predefined SSB-ToMeasure parameter, the method for the UE to perform measurement relaxation based on the predefined measurement relaxation parameters and the measurement configuration information of the normal measurement state may specifically include: replacing the SSB-ToMeasure parameter in the measurement configuration information of the normal measurement state with the predefined SSB-ToMeasure parameter.

[0169] For example, in one embodiment of this disclosure, it is assumed that the number of measurement beams corresponding to the SSB-ToMeasure parameter under normal measurement conditions is 32, and the number of measurement beams corresponding to the predefined SSB-ToMeasure parameter is 8. Then, when the UE performs measurement relaxation based on the predefined SSB-ToMeasure parameter, the UE performs RRM measurement according to the predefined SSB-ToMeasure parameter 8.

[0170] In another embodiment of this disclosure, when the measurement relaxation parameters include predefined types of pilot signals to be measured, the method for the UE to perform measurement relaxation based on the predefined measurement relaxation parameters and measurement configuration information of the normal measurement state may specifically include: replacing the types of pilot signals to be measured in the normal measurement state with the predefined types of pilot signals to be measured. For example, in one embodiment of this disclosure, assuming the pilot signals to be measured in the normal measurement state are SSB and CSI-RS (Channel State Information Reference Signal), and the predefined type of pilot signal to be measured is SSB, then when the UE performs measurement relaxation based on the predefined type of pilot signal to be measured, the UE can measure only the pilot signal SSB.

[0171] Furthermore, it should be noted that in one embodiment of this disclosure, when the predefined measurement relaxation parameters include at least two of the parameters in step 405 above, the UE can perform measurement relaxation based on a combination of at least two predefined measurement relaxation parameters and measurement configuration information of the normal measurement state.

[0172] For example, in one embodiment of this disclosure, it is assumed that the predefined measurement relaxation parameters received by the UE include a predefined measurement period spread factor and a predefined pilot signal to be measured: the pilot signal SSB. Then, the UE can multiply the measurement period in the normal measurement state by the predefined measurement period spread factor K to obtain a new measurement period, and perform measurement only on the pilot signal SSB based on the new measurement period. Other measurement parameters (e.g., measurement frequency, SMTC period and window length, SSB-ToMeasure parameter) can be measured according to the measurement relaxation parameters in the normal measurement state.

[0173] It should also be noted that, in one embodiment of this disclosure, when the idle-state UE meets different relaxation criteria, the contents of the corresponding predefined measurement relaxation parameters can be the same.

[0174] In another embodiment of this disclosure, the contents of the predefined measurement relaxation parameters may differ when the idle-state UE meets different relaxation criteria. Furthermore, in another embodiment of this disclosure, when the contents of the predefined measurement relaxation parameters for UEs under different relaxation criteria differ, the relaxation degree of the predefined measurement relaxation parameters for a UE meeting the stationary criterion may be greater than the relaxation degree of the predefined measurement relaxation parameters for a UE meeting the low mobility criterion and also greater than the relaxation degree of the predefined measurement relaxation parameters for a UE meeting the not-at-cell-edge criterion.

[0175] For example, in one embodiment of this disclosure, the predefined measurement relaxation parameters for a UE that meets the stationary criterion may include: a predefined measurement period spread factor; the predefined measurement relaxation parameters for a UE that meets the low mobility criterion may include: a predefined measurement frequency; and the predefined measurement relaxation parameters for a UE that meets the not-at-cell-edge criterion may include: a predefined SSB-ToMeasure parameter.

[0176] In summary, in the RRM measurement relaxation indication method provided in this disclosure, when a UE switches from a non-connected state to a connected state, and is in a measurement relaxation state before switching to the connected state, it sends status indication information to the base station, and then obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station. Based on at least one of the relaxation indication information and relaxation measurement configuration information, the UE's measurement state is determined. Therefore, in this disclosure embodiment, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it sends status indication information to the base station and obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station based on the status indication information. This allows the UE to directly enter the measurement relaxation state when its measurement state is connected, based on at least one of the relaxation indication information and relaxation measurement configuration information. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in a non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

[0177] Figure 5 This is a flowchart illustrating an RRM measurement relaxation indication method provided in yet another embodiment of this disclosure, applied to a UE, such as... Figure 5 As shown, the RRM measurement relaxation indication method may include the following steps:

[0178] Step 501: When the UE is in an idle state, determine whether the UE meets the relaxation criteria.

[0179] In one embodiment of this disclosure, the relaxation criteria may include at least one of the following: low mobility criterion, not at cell edge criterion, and stationary criterion.

[0180] Furthermore, if the UE meets the relaxation criteria, the UE's measurement state is determined to be in a relaxed state, and step 502 is executed. Otherwise, the UE's measurement state is determined to be in a normal measurement state.

[0181] Step 502: Switch from idle state to connected state and send status indication information to the base station.

[0182] Step 503: Obtain relaxation indication information from the base station. The relaxation indication information is used to indicate that the measurement status of the UE is in a measurement relaxation state.

[0183] Step 504: Obtain the measurement configuration information of the normal measurement status transmitted by the base station.

[0184] For a detailed description of steps 501 to 504, please refer to the relevant descriptions in the above embodiments. This disclosure will not repeat them here.

[0185] Step 505: Relax the measurement configuration information under normal measurement conditions to obtain relaxed measurement configuration information.

[0186] In one embodiment of this disclosure, the method for relaxing the measurement configuration information under normal measurement conditions may include at least one of the following:

[0187] Stop normal measurements of the UE;

[0188] Reduce the measurement frequency in the measurement configuration information under normal measurement conditions;

[0189] Add the SMTC cycle to the measurement configuration information under normal measurement conditions;

[0190] Provides an expansion factor for the measurement cycle in the measurement configuration information under normal measurement conditions;

[0191] Reduce the window length of SMTC in the measurement configuration information under normal measurement conditions;

[0192] Reduce the number of SSB-ToMeasure parameters in the measurement configuration information under normal measurement conditions;

[0193] Reduce the types of pilot signals that need to be measured in the measurement configuration information under normal measurement conditions.

[0194] In one embodiment of this disclosure, the relaxation processing method may be any one of the above methods. In another embodiment of this disclosure, the relaxation processing method may be any combination of two, three, four, five, or six of the above methods, or all seven of the above parameters.

[0195] Furthermore, in one embodiment of this disclosure, the relaxed measurement configuration information obtained is also different when the content included in the relaxation process is different.

[0196] Specifically, in one embodiment of this disclosure, when the relaxation process includes stopping normal measurements of the UE, normal measurements of the UE can be stopped for a period of time to achieve the relaxation process.

[0197] For example, normal measurements of the UE could be stopped for one hour.

[0198] Furthermore, in another embodiment of this disclosure, when the relaxation process includes reducing the measurement frequency in the measurement configuration information of the normal measurement state, the relaxation process performed on the measurement configuration information of the normal measurement state to obtain the relaxed measurement configuration information includes reducing its measurement frequency to obtain the reduced measurement frequency, and constructing the relaxed measurement configuration information based on the reduced measurement frequency.

[0199] For example, if the measurement frequency of the measurement configuration information in the normal measurement state includes 3GHz and 4GHz, the measurement frequency can be reduced to include only 3GHz to obtain the relaxed measurement configuration information.

[0200] In another embodiment of this disclosure, when the relaxation process includes increasing the period of the SMTC in the measurement configuration information of the normal measurement state, the relaxation process performed on the measurement configuration information of the normal measurement state to obtain the relaxed measurement configuration information includes increasing the period of its SMTC to obtain the increased period of the SMTC, and constructing the relaxed measurement configuration information based on the increased period of the SMTC.

[0201] For example, if the SMTC period for the measurement configuration information in normal measurement state includes 5ms, then the SMTC period can be increased to 20ms to obtain the relaxed measurement configuration information.

[0202] In another embodiment of this disclosure, when the relaxation process includes providing an expansion factor for the measurement period in the measurement configuration information of the normal measurement state, the relaxation process performed on the measurement configuration information of the normal measurement state to obtain relaxed measurement configuration information includes: determining the product of the expansion factor and the measurement period in the normal measurement state as the measurement period in the relaxed measurement state, and constructing the relaxed measurement configuration information based on the measurement period in the relaxed measurement state. In one embodiment of this disclosure, the expansion factor can specifically be a natural number greater than 1.

[0203] In another embodiment of this disclosure, when the relaxation process includes reducing the window length of the SMTC in the measurement configuration information of the normal measurement state, the relaxation process performed on the measurement configuration information of the normal measurement state to obtain the relaxed measurement configuration information includes reducing the window length of its SMTC to obtain the reduced window length of the SMTC, and constructing the relaxed measurement configuration information based on the reduced window length of the SMTC.

[0204] For example, if the SMTC window length for the measurement configuration information in normal measurement state includes 5ms, then the SMTC window length can be reduced to 3ms to obtain the relaxed measurement configuration information.

[0205] In another embodiment of this disclosure, when the relaxation process includes reducing the number of SSB-ToMeasure parameters in the measurement configuration information of the normal measurement state, the relaxation process performed on the measurement configuration information of the normal measurement state to obtain the relaxed measurement configuration information includes reducing the number of its SSB-ToMeasure parameters to obtain the reduced number of SSB-ToMeasure parameters, and constructing the relaxed measurement configuration information based on the reduced number of SSB-ToMeasure parameters.

[0206] For example, if the number of SSB-ToMeasure parameters in the measurement configuration information under normal measurement conditions is 32, the number of SSB-ToMeasure parameters can be reduced to 8 to obtain the relaxed measurement configuration information.

[0207] In another embodiment of this disclosure, when the relaxation process includes reducing the number of pilot signals to be measured in the measurement configuration information of the normal measurement state, the relaxation process performed on the measurement configuration information of the normal measurement state to obtain the relaxed measurement configuration information includes reducing the number of pilot signals to be measured to obtain the reduced number of pilot signals to be measured, and constructing the relaxed measurement configuration information based on the reduced number of pilot signals to be measured.

[0208] For example, if the types of pilot signals that need to be measured in the measurement configuration information of the normal measurement state include SSB and CSI-RS, then the types of pilot signals that need to be measured can be reduced to SSB to obtain the relaxed measurement configuration information.

[0209] Furthermore, it should be noted that in one embodiment of this disclosure, when the relaxation process includes at least two of the above methods, the UE can perform relaxation processing on the measurement configuration information of the normal measurement state based on at least two relaxation processing methods, and combine it with other parameters of the normal measurement state to obtain the relaxed measurement configuration information.

[0210] Specifically, in another embodiment of this disclosure, when the relaxation process includes: providing an expansion factor for the measurement period in the measurement configuration information of the normal measurement state and reducing the types of pilot signals that need to be measured in the measurement configuration information of the normal measurement state, the relaxation process performed on the measurement configuration information of the normal measurement state to obtain the relaxed measurement configuration information includes: determining the product of the expansion factor and the measurement period in the normal measurement state as the measurement period in the relaxed measurement state, and reducing the types of pilot signals that need to be measured to obtain the reduced types of pilot signals that need to be measured, and constructing the relaxed measurement configuration information based on the measurement period in the relaxed measurement state and the reduced types of pilot signals that need to be measured, combined with other parameters in the normal measurement state other than the measurement period and the types of pilot signals that need to be measured.

[0211] It should also be noted that, in one embodiment of this disclosure, when the idle UE meets different relaxation criteria, the relaxation processing of the corresponding measurement configuration information for the normal measurement state can be the same.

[0212] In another embodiment of this disclosure, when an idle-state UE meets different relaxation criteria, the relaxation processing of the measurement configuration information for the normal measurement state can be different. Furthermore, in another embodiment of this disclosure, when the relaxation processing of the measurement configuration information for the normal measurement state differs for UEs under different relaxation criteria, the degree of relaxation of the measurement configuration information for the normal measurement state performed on a UE that meets the stationary criterion can be greater than the degree of relaxation of the measurement configuration information for the normal measurement state performed on a UE that meets the low mobility criterion, and greater than the degree of relaxation of the measurement configuration information for the normal measurement state performed on a UE that meets the not-at-cell-edge criterion.

[0213] For example, in one embodiment of this disclosure, the relaxation process for the measurement configuration information of a UE in normal measurement state corresponding to a UE that meets the stationary criterion may include: stopping normal measurement of the UE; the relaxation process for the measurement configuration information of a UE in normal measurement state corresponding to a UE that meets the low mobility criterion may include: providing an expansion factor for the measurement period in the measurement configuration information of normal measurement state; the relaxation process for the measurement configuration information of a UE in normal measurement state corresponding to a UE that meets the not-at-cell-edge criterion may include: reducing the measurement frequency in the measurement configuration information of normal measurement state.

[0214] Step 506: Perform measurement relaxation based on the relaxed measurement configuration information to determine the measurement state of the connected UE as the measurement relaxation state.

[0215] In one embodiment of this disclosure, when the relaxation processing method in step 505 is different, the specific operation of performing measurement relaxation based on the relaxed measurement configuration information is also different.

[0216] Specifically, in one embodiment of this disclosure, when the relaxation process in step 505 is to stop normal measurement of the UE, the method for the UE to perform measurement relaxation based on the relaxed measurement configuration information may specifically include: stopping normal measurement of the UE for a period of time.

[0217] For example, in one embodiment of this disclosure, suppose normal measurements of the UE are stopped for one hour. Then the UE can stop RRM measurements for one hour.

[0218] In another embodiment of this disclosure, when the relaxation process in step 505 is to reduce the measurement frequency in the measurement configuration information of the normal measurement state, the method for the UE to perform measurement relaxation based on the relaxed measurement configuration information may specifically include: the UE performing measurement based on the reduced measurement frequency.

[0219] For example, in one embodiment of this disclosure, it is assumed that the reduced measurement frequency is 3 GHz. Then the UE can only measure the measurement identifiers that include the 3 GHz frequency band, while not measuring the measurement identifiers that include other frequency bands, thereby achieving relaxed measurement.

[0220] In another embodiment of this disclosure, when the relaxation process in step 505 is to increase the period of SMTC in the measurement configuration information of the normal measurement state, the method of UE performing measurement relaxation based on the relaxed measurement configuration information may specifically include: UE performing measurement only based on the increased period of SMTC.

[0221] For example, in one embodiment of this disclosure, it is assumed that the period of the increased SMTC is 20ms. Then the UE can perform RRM measurement based on the increased SMTC period of 20ms, thereby achieving relaxed measurement.

[0222] In another embodiment of this disclosure, when the relaxation process in step 505 is to provide an extension factor for the measurement period in the measurement configuration information of the normal measurement state, the method for the UE to perform measurement relaxation based on the relaxed measurement configuration information may specifically include: the UE performing measurement based on the period in the relaxed measurement state.

[0223] For example, in one embodiment of this disclosure, it is assumed that an extension factor K is provided in the measurement configuration information for the normal measurement state. Then, the UE can perform RRM measurement based on the measurement period in the relaxed measurement state determined by the product of the measurement period in the normal measurement state and K, thereby realizing relaxed measurement.

[0224] In another embodiment of this disclosure, when the relaxation process in step 505 is to reduce the window length of the SMTC in the measurement configuration information of the normal measurement state, the method for the UE to perform measurement relaxation based on the relaxed measurement configuration information may specifically include: the UE performing measurement based on the reduced window length of the SMTC.

[0225] For example, in one embodiment of this disclosure, it is assumed that the window length of the reduced SMTC is 3ms. Then the UE can perform RRM measurement based on the window length of the reduced SMTC of 3ms, thereby achieving relaxed measurement.

[0226] In another embodiment of this disclosure, when the relaxation process in step 505 is to reduce the number of SSB-ToMeasure parameters in the measurement configuration information of the normal measurement state, the method for the UE to perform measurement relaxation based on the relaxed measurement configuration information may specifically include: the UE performing measurement based on the reduced number of SSB-ToMeasure parameters.

[0227] For example, in one embodiment of this disclosure, it is assumed that the reduced number of SSB-ToMeasure parameters is 8. The UE can then perform RRM measurements based on the reduced number of SSB-ToMeasure parameters (8), thereby achieving relaxed measurement.

[0228] In another embodiment of this disclosure, when the relaxation process in step 505 is to reduce the types of pilot signals that need to be measured in the measurement configuration information of the normal measurement state, the method of the UE performing measurement relaxation based on the relaxed measurement configuration information may specifically include: the UE performing measurement based on the reduced types of pilot signals that need to be measured.

[0229] In summary, in the RRM measurement relaxation indication method provided in this disclosure, when a UE switches from a non-connected state to a connected state, and is in a measurement relaxation state before switching to the connected state, it sends status indication information to the base station, and then obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station. Based on at least one of the relaxation indication information and relaxation measurement configuration information, the UE's measurement state is determined. Therefore, in this disclosure embodiment, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it sends status indication information to the base station and obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station based on the status indication information. This allows the UE to directly enter the measurement relaxation state when its measurement state is connected, based on at least one of the relaxation indication information and relaxation measurement configuration information. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in a non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

[0230] Figure 6 This is a flowchart illustrating an RRM measurement relaxation indication method provided in yet another embodiment of this disclosure, applied to a UE, such as... Figure 6 As shown, the RRM measurement relaxation indication method may include the following steps:

[0231] Step 601: When the UE is in an idle state, determine whether the UE meets the relaxation criteria.

[0232] In one embodiment of this disclosure, the relaxation criteria may include at least one of the following: low mobility criterion, not at cell edge criterion, and stationary criterion.

[0233] Furthermore, if the UE meets the relaxation criteria, the UE's measurement state is determined to be in a relaxed state, and step 602 is executed. Otherwise, the UE's measurement state is determined to be in a normal measurement state.

[0234] Step 602: Switch from idle state to connected state and send status indication information to the base station.

[0235] Step 603: Obtain relaxation measurement configuration information and relaxation instruction information from the base station.

[0236] Step 604: Determine the measurement status of the UE based on the relaxation instruction information and the relaxation measurement configuration information.

[0237] For a detailed description of steps 601 to 604, please refer to the relevant descriptions in the above embodiments. This disclosure will not repeat them here.

[0238] In summary, in the RRM measurement relaxation indication method provided in this disclosure, when a UE switches from a non-connected state to a connected state, and is in a measurement relaxation state before switching to the connected state, it sends status indication information to the base station, and then obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station. Based on at least one of the relaxation indication information and relaxation measurement configuration information, the UE's measurement state is determined. Therefore, in this disclosure embodiment, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it sends status indication information to the base station and obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station based on the status indication information. This allows the UE to directly enter the measurement relaxation state when its measurement state is connected, based on at least one of the relaxation indication information and relaxation measurement configuration information. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in a non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

[0239] Figure 7 This is a flowchart illustrating an RRM measurement relaxation indication method provided in yet another embodiment of this disclosure, applied to a UE, such as... Figure 7 As shown, the RRM measurement relaxation indication method may include the following steps:

[0240] Step 701: When the UE is in an inactive state, determine whether the UE meets the relaxation criteria.

[0241] In one embodiment of this disclosure, the relaxation criteria may include at least one of the following: low mobility criterion, not at cell edge criterion, and stationary criterion.

[0242] Furthermore, for a detailed description of the method for determining whether the UE meets the relaxation criteria, please refer to the relevant descriptions in the above embodiments. This disclosure will not elaborate further here.

[0243] Furthermore, if the UE meets the relaxation criteria, the UE's measurement state is determined to be in a relaxed state, and step 702 is executed. Otherwise, the UE's measurement state is determined to be in a normal measurement state.

[0244] Step 702: Switch from inactive state to connected state and send status indication information to the base station.

[0245] In one embodiment of this disclosure, the method for sending status indication information to the base station when the UE switches from an inactive state to a connected state may include any of the following:

[0246] The first method involves sending status indication information to the base station via an RRC Resume Request message.

[0247] The second method is to send status indication information to the base station via the RRC Resume Request 1 message.

[0248] The third method involves sending a status indication message to the base station via an RRC Resume Complete message.

[0249] Step 703: Obtain relaxation measurement configuration information from the base station.

[0250] In one embodiment of this disclosure, when the UE sends status indication information to the base station through the first or second method in step 702 above, the method for the UE to obtain the relaxation measurement configuration information sent by the base station may include: obtaining the relaxation measurement configuration information sent by the base station through the RRC Resume (connection recovery) message.

[0251] Furthermore, in another embodiment of this disclosure, when the UE sends status indication information to the base station through the third method in step 702 above, the method for the UE to obtain the relaxation measurement configuration information sent by the base station may include: obtaining the relaxation measurement configuration information of the base station's secondary RRC reconfiguration. It should be noted that although the base station reconfigures the relaxation measurement configuration information through secondary RRC reconfiguration, the UE does not need to perform unnecessary RRM measurements or additional reporting during this secondary RRC reconfiguration process, thus reducing signaling overhead and saving power consumption.

[0252] For a detailed description of the relaxation measurement configuration information, please refer to the relevant descriptions in the above embodiments. This disclosure will not repeat the details here.

[0253] Step 704: Perform measurement relaxation based on the relaxed measurement configuration information to determine the measurement state of the connected UE as the measurement relaxation state.

[0254] For a detailed description of performing measurement relaxation based on relaxation measurement configuration information, please refer to the relevant descriptions in the above embodiments. This disclosure will not repeat the details here.

[0255] In summary, in the RRM measurement relaxation indication method provided in this disclosure, when a UE switches from a non-connected state to a connected state and its measurement state is in a measurement relaxation state, it sends a status indication message to the base station. It then obtains at least one of the relaxation indication message and relaxation measurement configuration information sent by the base station, and based on the information sent by the base station, changes the measurement state of the UE in the connected state to a measurement relaxation state. Therefore, in this disclosure, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it sends a status indication message to the base station and obtains at least one of the relaxation indication message and relaxation measurement configuration information sent by the base station based on the status indication message. This allows the UE to directly enter the measurement relaxation state based on at least one of the relaxation indication message and relaxation measurement configuration information when its measurement state is connected. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in the non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

[0256] Figure 8 This is a flowchart illustrating an RRM measurement relaxation indication method provided in yet another embodiment of this disclosure, applied to a UE, such as... Figure 8 As shown, the RRM measurement relaxation indication method may include the following steps:

[0258] In one embodiment of this disclosure, the relaxation criteria may include at least one of the following: low mobility criterion, not at cell edge criterion, and stationary criterion.

[0259] Furthermore, for a detailed description of the method for determining whether the UE meets the relaxation criteria, please refer to the relevant descriptions in the above embodiments. This disclosure will not elaborate further here.

[0260] Furthermore, if the UE meets the relaxation criteria, the UE's measurement state is determined to be in a relaxed state, and step 802 is executed. Otherwise, the UE's measurement state is determined to be in a normal measurement state.

[0261] Step 802: Switch from inactive state to connected state and send status indication information to the base station.

[0262] In one embodiment of this disclosure, the method for sending status indication information to the base station when the UE switches from an inactive state to a connected state may include any of the following:

[0263] The first method involves sending status indication information to the base station via an RRC Resume Request message.

[0264] The second method is to send status indication information to the base station via the RRC Resume Request 1 message.

[0265] The third method involves sending a status indication message to the base station via an RRC Resume Complete message.

[0266] Step 803: Obtain relaxation indication information from the base station. The relaxation indication information is used to indicate that the measurement status of the UE is in a measurement relaxation state.

[0267] In one embodiment of this disclosure, when the UE sends status indication information to the base station through the first or second method in step 802 above, the method for the UE to obtain the relaxation indication information sent by the base station may include: obtaining the relaxation measurement configuration information sent by the base station through the RRC Resume message.

[0268] Furthermore, in another embodiment of this disclosure, when the UE sends status indication information to the base station through the third method in step 802 above, the method for the UE to obtain the relaxation indication information sent by the base station may include: obtaining the relaxation indication information of the base station's secondary RRC reconfiguration. It should be noted that although the base station uses secondary RRC reconfiguration to obtain the relaxation indication information, during this secondary RRC reconfiguration process, the UE does not need to perform unnecessary RRM measurements or additional reporting, thus reducing signaling overhead and saving power consumption.

[0269] Step 804: Obtain the measurement configuration information of the normal measurement status sent by the base station.

[0270] In one embodiment of this disclosure, the method for a UE to obtain measurement configuration information of normal measurement status sent by a base station may include: obtaining measurement configuration information of normal measurement status sent by the base station through an RRC Resume message.

[0271] Step 805: Obtain the predefined measurement relaxation parameters indicated by the base station.

[0272] In one embodiment of this disclosure, the method for the UE to obtain predefined measurement relaxation parameters indicated by the base station may include at least one of the following:

[0273] The first method involves obtaining predefined measurement relaxation parameters sent by the base station via system messages. For example, in one embodiment of this disclosure, predefined measurement relaxation parameters can be obtained by the base station broadcasting them via SIB X, where X can be any SIB.

[0274] The second method involves obtaining predefined measurement relaxation parameters indicated by the base station based on a protocol. For example, in one embodiment of this disclosure, predefined measurement relaxation parameters indicated by the base station based on the TS38.331 protocol can be obtained.

[0275] The third method involves obtaining predefined measurement relaxation parameters sent by the base station via RRC messages. For example, in one embodiment of this disclosure, predefined measurement relaxation parameters sent by the base station to the UE via an RRC Resume message can be obtained.

[0276] Fourth, obtain the predefined measurement relaxation parameters carried in the relaxation instruction information.

[0277] Specifically, in one embodiment of this disclosure, the UE can obtain predefined measurement relaxation parameters using only the first, second, third, or fourth method described above. In another embodiment of this disclosure, the method by which the UE obtains the predefined measurement relaxation parameters indicated by the base station can also be any combination of two or three of the above methods, or all four of the above methods.

[0278] Step 806: Perform measurement relaxation based on predefined measurement relaxation parameters and measurement configuration information of normal measurement state to determine the measurement state of the connected UE as the measurement relaxation state.

[0279] For a detailed description of steps 805 to 806, please refer to the relevant descriptions in the above embodiments. This disclosure will not repeat the details here.

[0280] In summary, in the RRM measurement relaxation indication method provided in this disclosure, when a UE switches from a non-connected state to a connected state, and is in a measurement relaxation state before switching to the connected state, it sends status indication information to the base station, and then obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station. Based on at least one of the relaxation indication information and relaxation measurement configuration information, the UE's measurement state is determined. Therefore, in this disclosure embodiment, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it sends status indication information to the base station and obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station based on the status indication information. This allows the UE to directly enter the measurement relaxation state when its measurement state is connected, based on at least one of the relaxation indication information and relaxation measurement configuration information. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in a non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

[0282] Step 901: When the UE is in an inactive state, determine whether the UE meets the relaxation criteria.

[0283] In one embodiment of this disclosure, the relaxation criteria may include at least one of the following: low mobility criterion, not at cell edge criterion, and stationary criterion.

[0284] Furthermore, for a detailed description of the method for determining whether the UE meets the relaxation criteria, please refer to the relevant descriptions in the above embodiments. This disclosure will not elaborate further here.

[0285] Furthermore, if the UE meets the relaxation criteria, the UE's measurement state is determined to be in a relaxed state, and step 902 is executed. Otherwise, the UE's measurement state is determined to be in a normal measurement state.

[0286] Step 902: Switch from inactive state to connected state and send status indication information to the base station.

[0287] Step 903: Obtain relaxation indication information from the base station. The relaxation indication information is used to indicate that the measurement status of the UE is in a measurement relaxation state.

[0288] Step 904: Obtain the measurement configuration information of the normal measurement status sent by the base station.

[0289] Step 905: Relax the measurement configuration information in the normal measurement state to obtain the relaxed measurement configuration information.

[0290] Step 906: Perform measurement relaxation based on the relaxed measurement configuration information to determine the measurement state of the connected UE as the measurement relaxation state.

[0291] For a detailed description of steps 901 to 906, please refer to the relevant descriptions in the above embodiments. This disclosure will not repeat them here.

[0292] In summary, in the RRM measurement relaxation indication method provided in this disclosure, when a UE switches from a non-connected state to a connected state, and is in a measurement relaxation state before switching to the connected state, it sends status indication information to the base station, and then obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station. Based on at least one of the relaxation indication information and relaxation measurement configuration information, the UE's measurement state is determined. Therefore, in this disclosure embodiment, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it sends status indication information to the base station and obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station based on the status indication information. This allows the UE to directly enter the measurement relaxation state when its measurement state is connected, based on at least one of the relaxation indication information and relaxation measurement configuration information. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in a non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

[0294] Step 1001: When the UE is in an inactive state, determine whether the UE meets the relaxation criteria.

[0295] In one embodiment of this disclosure, the relaxation criteria may include at least one of the following: low mobility criterion, not at cell edge criterion, and stationary criterion.

[0296] Furthermore, if the UE meets the relaxation criteria, the UE's measurement state is determined to be in a relaxed state, and step 1002 is executed. Otherwise, the UE's measurement state is determined to be in a normal measurement state.

[0297] Step 1002: Switch from inactive state to connected state and send status indication information to the base station.

[0298] Step 1003: Obtain relaxation measurement configuration information and relaxation instruction information from the base station.

[0299] Step 1004: Determine the measurement status of the UE based on the relaxation instruction information and the relaxation measurement configuration information.

[0300] For a detailed description of steps 1001 to 1004, please refer to the relevant descriptions in the above embodiments. This disclosure will not repeat the details here.

[0301] In summary, in the RRM measurement relaxation indication method provided in this disclosure, when a UE switches from a non-connected state to a connected state, and is in a measurement relaxation state before switching to the connected state, it sends status indication information to the base station, and then obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station. Based on at least one of the relaxation indication information and relaxation measurement configuration information, the UE's measurement state is determined. Therefore, in this disclosure embodiment, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it sends status indication information to the base station and obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station based on the status indication information. This allows the UE to directly enter the measurement relaxation state when its measurement state is connected, based on at least one of the relaxation indication information and relaxation measurement configuration information. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in a non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

[0302] Figure 11 This is a flowchart illustrating an RRM measurement relaxation indication method provided in yet another embodiment of this disclosure, applied to a UE, such as... Figure 11 As shown, the RRM measurement relaxation indication method may include the following steps:

[0303] Step 1101: Send UE capability information to the base station. The UE capability information is used to indicate whether the UE has the ability to report measurement status.

[0304] In one embodiment of this disclosure, when the UE has the ability to report measurement status, the UE can send UE capability information to the base station to indicate that the UE has the ability to report measurement status.

[0305] Step 1102: Receive reporting indication information from the base station. The reporting indication information is used to indicate whether the UE allows reporting the measurement status to the base station.

[0306] In one embodiment of this disclosure, the method for a UE to receive reporting indication information from a base station may specifically include: receiving reporting indication information sent by the base station through a system message.

[0307] Furthermore, in another embodiment of this disclosure, the method for the UE to receive reporting indication information from the base station may specifically include: when the UE releases the RRC connection, receiving reporting indication information sent by the base station through an RRC message (e.g., an RRC release message).

[0308] Step 1103: Switch from non-connected state to connected state, and when the UE is in measurement relaxation state before switching to connected state, send status indication information to the base station.

[0309] In one embodiment of this disclosure, when the UE capability information indicates that the UE has the ability to report measurement status, and the reporting indication information indicates that the UE is allowed to report measurement status to the base station, then when the UE switches from a non-connected state to a connected state, the UE can send status indication information to the base station so as to receive at least one of relaxation indication information and relaxation measurement configuration information sent by the base station according to the status indication information, and directly determine the UE's measurement status as a measurement relaxation state when entering the connected state based on the indication information and / or relaxation measurement configuration information.

[0310] Furthermore, for a detailed description of sending status indication information to the base station, please refer to the relevant descriptions in the above embodiments; the embodiments disclosed herein will not be repeated here.

[0311] Step 1104: Obtain at least one of relaxation instruction information and relaxation measurement configuration information from the base station.

[0312] Step 1105: Determine the measurement status of the UE based on at least one of the relaxation instruction information and the relaxation measurement configuration information.

[0313] For a detailed description of steps 1104 to 1105, please refer to the relevant descriptions in the above embodiments. This disclosure will not repeat the details here.

[0314] In summary, in the RRM measurement relaxation indication method provided in this disclosure, when a UE switches from a non-connected state to a connected state, and is in a measurement relaxation state before switching to the connected state, it sends status indication information to the base station, and then obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station. Based on at least one of the relaxation indication information and relaxation measurement configuration information, the UE's measurement state is determined. Therefore, in this disclosure embodiment, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it sends status indication information to the base station and obtains at least one of relaxation indication information and relaxation measurement configuration information from the base station based on the status indication information. This allows the UE to directly enter the measurement relaxation state when its measurement state is connected, based on at least one of the relaxation indication information and relaxation measurement configuration information. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in a non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

[0315] Figure 12 This is a flowchart illustrating an RRM measurement relaxation indication method provided in yet another embodiment of the present disclosure, applied to a base station, such as... Figure 12 As shown, the RRM measurement relaxation indication method may include the following steps:

[0316] Step 1201: Receive status indication information from the UE.

[0317] In one embodiment of this disclosure, the base station can receive status indication information sent by the UE through RRC messages during the RRC connection establishment / restore process. Specifically, in one embodiment of this disclosure, when the UE switches from an idle state to a connected state, and was in a measurement relaxation state before switching to the connected state, the base station can receive the UE's transmission status indication information through RRC messages during the RRC connection establishment process. In another embodiment of this disclosure, when the UE switches from an inactive state to a connected state, and was in a measurement relaxation state before switching to the connected state, the base station can receive the UE's status indication information through RRC messages during the RRC connection restore process.

[0318] Furthermore, in one embodiment of this disclosure, the state indication information can be used to indicate that the UE is in a measurement relaxation state before switching to the connected state. Also, in another embodiment of this disclosure, the state indication information can be used to indicate the specific relaxation criterion (e.g., low mobility criterion, not at cell edge criterion, and stationary criterion) that the UE is in before switching to the connected state.

[0319] Step 1202: Send at least one of relaxation instruction information and relaxation measurement configuration information to the UE.

[0320] In one embodiment of this disclosure, the base station may send only relaxation indication information to the UE. In another embodiment of this disclosure, the base station may send only relaxation measurement configuration information to the UE. In yet another embodiment of this disclosure, the base station may send both relaxation indication information and relaxation measurement configuration information to the UE.

[0321] In summary, in the RRM measurement relaxation indication method provided in this embodiment, the base station can receive status indication information sent by the UE via RRC messages during the RRC connection establishment / recovery process, and send at least one of relaxation indication information and relaxation measurement configuration information to the UE. Therefore, in this embodiment, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it will send status indication information to the base station and obtain at least one of the relaxation indication information and relaxation measurement configuration information sent by the base station based on the status indication information. This allows the UE to directly enter the measurement relaxation state based on at least one of the relaxation indication information and relaxation measurement configuration information when switching to the connected state. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in the non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

In another embodiment of this disclosure, the state indication information can also be used to indicate the specific relaxation criteria met by the UE before switching to the connected state, such as indicating that the low mobility criterion is met, or indicating that the non-cell edge criterion is met, or indicating that the stationary criterion is met, etc.

[0325] Furthermore, in one embodiment of this disclosure, the method by which the base station receives status indication information sent by the UE via RRC messages during the RRC connection establishment process may specifically include any one of the following methods:

[0326] First, receive status indication information sent by the UE via the RRC Setup Request message.

[0327] Second, receive the status indication information sent by the UE through the newly established RRC Setup Request 1 message.

[0328] Third, receive status indication information sent by the UE via the RRC Setup Complete message.

[0329] Step 1302: Send relaxation measurement configuration information to the UE.

[0330] In another embodiment of this disclosure, when the base station receives the status indication information sent by the UE through any one of the first to third methods in step 1301 above, the method for the base station to send the relaxation measurement configuration information to the UE may include: sending the relaxation measurement configuration information to the UE through an RRC Reconfiguration message.

[0331] Furthermore, in one embodiment of this disclosure, the relaxation measurement configuration information may include at least one of the following:

[0332] Delete the measurement configuration information in the normal measurement state;

[0333] The number of new measurement frequencies is less than the number of measurement frequencies in the normal measurement state.

[0334] The new SMTC has a longer period than the SMTC in normal measurement conditions.

[0335] The new SMTC has a smaller window length than the SMTC in normal measurement mode.

[0336] The new SSB-ToMeasure parameter corresponds to a smaller number of measurements than the SSB-ToMeasure parameter under normal measurement conditions.

[0337] The new pilot signals that need to be measured are fewer in number than the pilot signals in the normal measurement state.

[0338] In one embodiment of this disclosure, the relaxation measurement configuration information may be any one of the above configuration information. In another embodiment of this disclosure, the relaxation measurement configuration information may be any pairwise combination, any three-way combination, any four-way combination, any five-way combination, or all six types of the above configuration information.

[0339] Furthermore, for a detailed description of the relaxation measurement configuration information, please refer to the relevant descriptions in the above embodiments; the embodiments disclosed herein will not be repeated here.

[0340] In summary, in the RRM measurement relaxation indication method provided in this embodiment, the base station can receive status indication information sent by the UE via RRC messages during the RRC connection establishment / recovery process, and send at least one of relaxation indication information and relaxation measurement configuration information to the UE. Therefore, in this embodiment, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it will send status indication information to the base station and obtain at least one of the relaxation indication information and relaxation measurement configuration information sent by the base station based on the status indication information. This allows the UE to directly enter the measurement relaxation state based on at least one of the relaxation indication information and relaxation measurement configuration information when switching to the connected state. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in the non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

[0341] Figure 14 This is a flowchart illustrating an RRM measurement relaxation indication method provided in yet another embodiment of the present disclosure, applied to a base station, such as... Figure 14 As shown, the RRM measurement relaxation indication method may include the following steps:

[0342] Step 1401: Receive status indication information sent by the UE through the RRC message during the RRC connection establishment process.

[0343] In one embodiment of this disclosure, the status indication information can be used to indicate that the UE is in a measurement relaxation state before switching to the connected state. In another embodiment of this disclosure, the status indication information can also be used to indicate the specific relaxation criteria (e.g., low mobility criterion, not at cell edge criterion, and stationary criterion) the UE is in before switching to the connected state.

[0344] Furthermore, in one embodiment of this disclosure, the method by which the base station receives status indication information sent by the UE via RRC messages during the RRC connection establishment process may specifically include any one of the following methods:

[0345] First, receive status indication information sent by the UE via the RRC Setup Request message.

[0346] Second, receive the status indication information sent by the UE through the newly established RRC Setup Request 1 message.

[0347] Third, receive status indication information sent by the UE via the RRC Setup Complete message.

[0348] Step 1402: Send a relaxation instruction message to the UE. The relaxation instruction message is used to indicate that the measurement status of the UE is in a measurement relaxation state.

[0349] In another embodiment of this disclosure, when the base station receives the status indication information sent by the UE through any one of the first to third methods in step 1401 above, the method by which the base station sends the relaxation indication information to the UE may include: sending at least one of the relaxation indication information and relaxation measurement configuration information to the UE through an RRC Reconfiguration message.

[0350] Furthermore, in one embodiment of this disclosure, when the base station receives the status indication information sent by the UE through the first or second method in step 1401 above, the method by which the base station sends the relaxation indication information to the UE may include: sending the relaxation indication information to the UE through an RRCSetup message.

[0351] Step 1403: Send measurement configuration information for normal measurement status to the UE.

[0352] In one embodiment of this disclosure, the method for a base station to send normal measurement configuration to a UE may include: sending measurement configuration information of normal measurement status to the UE via an RRC Reconfiguration message.

[0353] Step 1404: Indicate the predefined measurement relaxation parameters to the UE.

[0354] In one embodiment of this disclosure, the method by which the base station indicates predefined measurement relaxation parameters to the UE may include at least one of the following:

[0355] The first method involves sending predefined measurement relaxation parameters to the connected UE via system messages. For example, in one embodiment of this disclosure, the base station can broadcast predefined measurement relaxation parameters via SIB X, where X can be any SIB.

[0356] The second method involves instructing predefined measurement relaxation parameters to the connected UE via a protocol. For example, in one embodiment of this disclosure, the base station may instruct predefined measurement relaxation parameters based on the TS38.331 protocol.

[0357] The third method involves sending predefined measurement relaxation parameters to the connected UE via RRC messages. For example, in one embodiment of this disclosure, the base station can send predefined measurement relaxation parameters to the UE via an RRC Reconfiguration message or an RRC Setup message.

[0358] Fourth, when sending relaxation instruction information to the UE, the predefined measurement relaxation parameter is included in the relaxation instruction information.

[0359] Specifically, in one embodiment of this disclosure, the base station may indicate predefined measurement relaxation parameters to the connected UE using only the first, second, third, or fourth method described above. In another embodiment of this disclosure, the method by which the base station indicates the predefined measurement relaxation parameters to the connected UE may also be any combination of two or three of the above methods, or all four of the above methods.

[0360] Furthermore, in one embodiment of this disclosure, measuring the relaxation parameters includes at least one of the following:

[0361] Predefined measurement period expansion factor;

[0362] The number of predefined measurement frequencies is less than the number of measurement frequencies in normal measurement conditions.

[0363] The predefined SMTC has a period longer than the SMTC period under normal measurement conditions.

[0364] The predefined SMTC has a smaller window length than the SMTC under normal measurement conditions.

[0365] The predefined SSB-ToMeasure parameter has a smaller number of measurements than the SSB-ToMeasure parameter under normal measurement conditions.

[0366] The predefined types of pilot signals to be measured are fewer than the types of pilot signals to be measured under the normal measurement state.

In another embodiment of this disclosure, the relaxation parameter can be any pairwise combination, any three-way combination, any four-way combination, any five-way combination, or all six of the above parameters.

[0368] Furthermore, for a detailed description of the measurement of relaxation parameters, please refer to the relevant descriptions in the above embodiments; the embodiments disclosed herein will not be repeated here.

[0369] Furthermore, in one embodiment of this disclosure, when the base station sends measurement configuration information of the normal measurement state to the UE via an RRC Reconfiguration message and indicates predefined measurement relaxation parameters to the UE, the UE can perform measurement relaxation based on the predefined measurement relaxation parameters and the measurement configuration information of the normal measurement state, so that the measurement state of the connected UE is determined to be the measurement relaxation state.

[0370] In summary, in the RRM measurement relaxation indication method provided in this embodiment, the base station can receive status indication information sent by the UE via RRC messages during the RRC connection establishment / recovery process, and send at least one of relaxation indication information and relaxation measurement configuration information to the UE. Therefore, in this embodiment, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it will send status indication information to the base station and obtain at least one of the relaxation indication information and relaxation measurement configuration information sent by the base station based on the status indication information. This allows the UE to directly enter the measurement relaxation state based on at least one of the relaxation indication information and relaxation measurement configuration information when switching to the connected state. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in the non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

[0371] Figure 15 This is a flowchart illustrating an RRM measurement relaxation indication method provided in yet another embodiment of the present disclosure, applied to a base station, such as... Figure 15 As shown, the RRM measurement relaxation indication method may include the following steps:

[0372] Step 1501: Receive the status indication information sent by the UE through the RRC message during the RRC connection establishment process.

[0373] Step 1502: Send a relaxation instruction message to the UE. The relaxation instruction message is used to indicate that the measurement status of the UE is determined to be a measurement relaxation state.

[0374] Step 1503: Send measurement configuration information for normal measurement status to the UE.

[0375] For a detailed description of steps 1501 to 1503, please refer to the relevant descriptions in the above embodiments. This disclosure will not repeat the details here.

[0376] Furthermore, in one embodiment of this disclosure, when the base station sends a relaxation indication message to the UE and sends normal measurement configuration information to the UE via an RRCReconfiguration message, the UE can perform relaxation processing on the normal measurement configuration information to obtain relaxed measurement configuration information, so that the UE can subsequently perform measurement relaxation based on the relaxed measurement configuration information, thereby making the measurement state of the connected UE a measurement relaxation state.

[0377] In summary, in the RRM measurement relaxation indication method provided in this embodiment, the base station can receive status indication information sent by the UE via RRC messages during the RRC connection establishment / recovery process, and send at least one of relaxation indication information and relaxation measurement configuration information to the UE. Therefore, in this embodiment, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it will send status indication information to the base station and obtain at least one of the relaxation indication information and relaxation measurement configuration information sent by the base station based on the status indication information. This allows the UE to directly enter the measurement relaxation state based on at least one of the relaxation indication information and relaxation measurement configuration information when switching to the connected state. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in the non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

Therefore, in this embodiment, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it will send status indication information to the base station and obtain at least one of the relaxation indication information and relaxation measurement configuration information sent by the base station based on the status indication information. This allows the UE to directly enter the measurement relaxation state based on at least one of the relaxation indication information and relaxation measurement configuration information when switching to the connected state. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in the non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

It should be noted that although the base station sends the relaxation measurement configuration information through a secondary RRC reconfiguration, during this secondary RRC reconfiguration process, the UE does not need to perform unnecessary RRM measurements or additional reporting, thus reducing signaling overhead and saving power consumption.

[0393] Furthermore, in one embodiment of this disclosure, the relaxation measurement configuration information may include at least one of the following:

This allows the UE to directly enter the measurement relaxation state based on at least one of the relaxation indication information and relaxation measurement configuration information when switching to the connected state. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in the non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

[0412] Furthermore, in another embodiment of this disclosure, when the base station receives the status indication information sent by the UE through the sixth method in step 1701 above, the method for the base station to send the relaxation measurement configuration information to the UE may include: sending the status indication information to the UE through a secondary RRC reconfiguration. It should be noted that although the base station sends the status indication information through a secondary RRC reconfiguration, during this secondary RRC reconfiguration process, the UE does not need to perform unnecessary RRM measurements or additional reporting, thus reducing signaling overhead and saving power consumption.

[0417] The first method involves sending predefined measurement relaxation parameters to the connected UE via system messages. For example, in one embodiment of this disclosure, the base station can broadcast predefined measurement relaxation parameters via SIB X, where X can be any SIB.

[0418] The second method involves instructing predefined measurement relaxation parameters to the connected UE via a protocol. For example, in one embodiment of this disclosure, the base station may instruct predefined measurement relaxation parameters based on the TS38.331 protocol.

[0419] The third method involves sending predefined measurement relaxation parameters to the connected UE via an RRC message. For example, in one embodiment of this disclosure, the base station can send predefined measurement relaxation parameters to the UE via an RRC Resume message.

[0420] Fourth, when sending relaxation instruction information to the UE, the predefined measurement relaxation parameter is included in the relaxation instruction information.

[0421] Specifically, in one embodiment of this disclosure, the base station may indicate predefined measurement relaxation parameters to the connected UE using only the first, second, third, or fourth method described above. In another embodiment of this disclosure, the method by which the base station indicates the predefined measurement relaxation parameters to the connected UE may also be any combination of two or three of the above methods, or all three of the above methods.

[0422] Furthermore, in one embodiment of this disclosure, measuring the relaxation parameters includes at least one of the following:

[0430] Furthermore, for a detailed description of the measurement of relaxation parameters, please refer to the relevant descriptions in the above embodiments; the embodiments disclosed herein will not be repeated here.

[0431] Furthermore, in one embodiment of this disclosure, when the base station sends measurement configuration information of normal measurement state to the UE via RRC Resume message and indicates predefined measurement relaxation parameters to the UE, the UE can perform measurement relaxation based on the predefined measurement relaxation parameters and the measurement configuration information of normal measurement state, so that the measurement state of the connected UE is in the measurement relaxation state.

[0432] In summary, in the RRM measurement relaxation indication method provided in this embodiment, the base station can receive status indication information sent by the UE via RRC messages during the RRC connection establishment / recovery process, and send at least one of relaxation indication information and relaxation measurement configuration information to the UE.

[0437] For a detailed description of steps 1901 to 1903, please refer to the relevant descriptions in the above embodiments. This disclosure will not repeat them here.

[0438] Furthermore, in one embodiment of this disclosure, when the base station sends a relaxation indication message to the UE and sends normal measurement configuration information to the UE via an RRRCResume message, the UE can perform relaxation processing on the normal measurement configuration information to obtain relaxed measurement configuration information, so that the UE can subsequently perform measurement relaxation based on the relaxed measurement configuration information, thereby making the measurement state of the connected UE a measurement relaxation state.

[0439] In summary, in the RRM measurement relaxation indication method provided in this embodiment, the base station can receive status indication information sent by the UE via RRC messages during the RRC connection establishment / recovery process, and send at least one of relaxation indication information and relaxation measurement configuration information to the UE.

[0445] Figure 21 This is a flowchart illustrating an RRM measurement relaxation indication method provided in yet another embodiment of the present disclosure, applied to a base station, such as... Figure 21 As shown, the RRM measurement relaxation indication method may include the following steps:

[0446] Step 2101: Receive UE capability information from the UE. The UE capability information is used to indicate whether the UE has the capability to report measurement status.

[0447] Step 2102: Send a reporting indication message to the UE. The reporting indication message is used to indicate whether the UE should report the measurement status to the base station.

[0448] In one embodiment of this disclosure, the method for a base station to send reporting indication information to a UE may include: sending reporting indication information to the UE via system messages.

[0449] Furthermore, in one embodiment of this disclosure, when the UE releases the RRC connection, the base station can send a reporting indication information to the UE via an RRC message, so that the UE can send a status indication information before the UE switches to the connected state to the base station, so that the base station can send at least one of relaxation indication information and relaxation measurement configuration information to the UE according to the status indication information.

[0450] Step 2103: Receive status indication information from the UE.

[0451] Step 2104: Send at least one of relaxation instruction information and relaxation measurement configuration information to the UE.

[0453] In summary, in the RRM measurement relaxation indication method provided in this embodiment, the base station can receive status indication information sent by the UE via RRC messages during the RRC connection establishment / recovery process, and send at least one of relaxation indication information and relaxation measurement configuration information to the UE. Therefore, in this embodiment, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it will send status indication information to the base station and obtain at least one of the relaxation indication information and relaxation measurement configuration information sent by the base station based on the status indication information. This allows the UE to directly enter the measurement relaxation state based on at least one of the relaxation indication information and relaxation measurement configuration information when switching to the connected state. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in the non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

[0454] Based on the above, the RRM measurement relaxation indication method in this embodiment of the present disclosure will be illustrated with an example:

[0455] Example 1

[0456] Figure 22 This is a flowchart illustrating a method for RRM measurement relaxation indication for an idle-state UE according to an embodiment of this disclosure, as shown below. Figure 22 As shown, the method may include the following steps:

[0457] Step 1: The base station releases the UE to the idle state through an RRC release message, and sends a reporting indication message to the UE through the RRC release message to indicate that the UE is allowed to report the measurement status to the base station, and that the UE has the ability to report the measurement status.

[0458] Step 2: When the UE is in idle state, it meets the stationary criterion and performs RRM measurement according to the measurement relaxation method of the stationary criterion, that is, RRM measurement is performed on neighboring cells every 12 hours.

[0459] Step 3: When the UE initiates random access (connection establishment), it carries the status indication information used by the UE to indicate the stationary state in Msg3 (RRC setup request) and sends it to the base station.

[0460] Step 4: The base station uses the RRC reconfiguration message during the connection establishment process to provide the UE with a set of relaxed measurement configuration information applicable to the stationary criterion. The relaxed measurement configuration information may include: configuring fewer measurement frequencies, configuring longer periods or providing period spread factors, reducing the types of pilot signals used for measurement, reducing the measurement window length (SMTC), etc.

[0461] Step 5: The UE performs RRM measurement in connected state according to the received relaxation measurement configuration information.

[0462] Example 2

[0463] Figure 23 A flowchart illustrating a relaxation indication method for RRM measurement of an idle-state UE, as provided in another embodiment of this disclosure, is shown below. Figure 23 As shown, the method may include the following steps:

[0464] Step 1: When the UE is in idle state, it meets the low mobility criterion and performs RRM measurement according to the measurement relaxation method of the low mobility criterion, that is, the measurement is performed by extending the regular RRM measurement cycle by 3 times.

[0465] Step 2: The base station broadcasts a reporting indication message to the UE via a system message, indicating that the UE is allowed to report the measurement status to the base station. Then, the UE with the ability to report the measurement status can report the measurement status (i.e., report the status indication message) when the connection is established.

[0466] Step 3: When the UE initiates random access (connection establishment), it carries the status indication information used by the UE to indicate the low mobility state in Msg5 (RRC setup complete) and sends it to the base station.

[0467] Step 4: The base station uses the RRC reconfiguration message during the connection establishment process to provide the UE with a set of relaxed measurement configuration information applicable to the stationary criterion. The relaxed measurement configuration information may include: configuring fewer measurement frequencies, configuring longer periods or providing period spread factors, reducing the types of pilot signals used for measurement, reducing the measurement window length (SMTC), etc.

[0468] Step 5: The UE performs RRM measurement in connected state according to the received relaxation measurement configuration information.

[0469] Example 3

[0470] Figure 24 A flowchart illustrating a relaxation indication method for RRM measurement of an inactive UE, as provided in another embodiment of this disclosure, is shown below. Figure 24 As shown, the method may include the following steps:

[0471] Step 1: The UE satisfies both the static and non-cell edge criteria in the inactive state, and performs RRM measurement according to the corresponding relaxation measurement method, that is, performs RRM measurement on adjacent cells once every 24 hours.

[0472] Step 2: When the UE initiates random access (connection recovery), it sends status indication information, which indicates whether it is in a stationary state or not in a cell edge state, to the base station in Msg3 (RRC resume request).

[0473] Step 3: The base station provides a set of relaxed measurement configuration information for the UE in Msg4 (RRC resume), which is applicable to the stationary criterion and the non-cell edge criterion. The relaxed measurement configuration information may include: configuring fewer measurement frequencies, configuring longer periods or providing period spread factors, reducing the types of pilot signals for measurement, and reducing the measurement window length (SMTC), etc.

[0474] Step 4: The UE performs RRM measurement in connected state according to the received relaxation measurement configuration information.

[0475] Example 4

[0476] Step 1: The UE in idle / disconnected state satisfies a certain measurement relaxation criterion, and RRM measurement is performed in disconnected state according to the measurement relaxation method corresponding to the criterion.

[0477] Step 2: When the UE initiates connection establishment / restore, it sends the corresponding status indication information to the base station in the random access Msg3 (RRC setup request / RRC resume request) message.

[0478] Step 3.1 In one manner, the base station may instruct the UE to perform measurement relaxation in the Msg4 (RRC setup / RRC resume) message. For example, the base station may send relaxation instruction information to the UE in the RRC reconfiguration or RRC resume message to instruct the UE to perform measurement relaxation.

[0479] Step 3.2, Alternatively, the base station can send relaxation measurement configuration information to the UE via an RRC reconfiguration message or an RRC resume message to instruct the UE to perform measurement relaxation.

[0480] Step 4: Upon receiving the RRM measurement relaxation instruction from the base station, the UE can either perform broadcast processing on the RRM measurement configuration information under normal measurement conditions, or perform measurement relaxation according to the predefined measurement relaxation parameters and RRM measurement configuration information under normal measurement conditions indicated by the base station. For example, if the base station indicates a predefined measurement period extension factor K1, the UE that meets the measurement relaxation criteria can multiply the measurement period under normal measurement conditions by K1 to obtain a new measurement period, and perform RRM measurement according to the new measurement period.

[0481] Figure 25 This is a schematic diagram of the structure of an RRM measurement relaxation indicator device provided in one embodiment of the present disclosure, as shown below. Figure 25 As shown, the device 2500 may include:

[0482] The transmitting module 2501 is used to switch from a non-connected state to a connected state, and to send a status indication information to the base station when the UE is in a measurement relaxation state before switching to the connected state;

[0483] The acquisition module 2502 is used for at least one of relaxation instruction information and relaxation measurement configuration information from the base station;

[0484] The switching module 2503 is used to determine the measurement status of the UE based on at least one of the relaxation instruction information and the relaxation measurement configuration information.

[0485] In summary, in the RRM measurement relaxation indication device provided in this embodiment, when a UE switches from a non-connected state to a connected state and its measurement state is in a measurement relaxation state, it sends a status indication message to the base station. It then obtains at least one of the relaxation indication message and relaxation measurement configuration information sent by the base station, and based on the information sent by the base station, changes the measurement state of the UE in the connected state to a measurement relaxation state. Therefore, in this embodiment, if the UE is in a measurement relaxation state before switching from a non-connected state to a connected state, it sends a status indication message to the base station and obtains at least one of the relaxation indication message and relaxation measurement configuration information sent by the base station based on the status indication message. This allows the UE to directly enter the measurement relaxation state based on at least one of the relaxation indication message and relaxation measurement configuration information when its measurement state is connected. In other words, only one RRC configuration is needed for the connected UE to inherit the measurement relaxation state of the non-connected UE. This avoids the need for a second RRC reconfiguration when a UE that satisfies measurement relaxation in the non-connected state enters the connected state, reducing redundant signaling interactions and measurement processes, lowering signaling overhead, and saving power consumption.

[0486] In one embodiment of this disclosure, the above-described apparatus is further used for:

[0487] When the UE is in a disconnected state, it is determined whether the UE meets the relaxation criteria. The relaxation criteria include at least one of the low mobility criteria, the non-cell edge criteria, and the stationary criteria.

[0488] If the UE meets the relaxation criteria, the measurement state of the UE is determined to be a measurement relaxation state;

[0489] If the UE does not meet the relaxation criteria, the UE's measurement status is determined to be a normal measurement status.
