Description

UE power saving methods, devices, communication equipment and storage media

[0001] This application is a divisional application of the invention patent application filed on March 18, 2021, with application number 202180000798.8 and invention title "UE power saving processing method, apparatus, communication equipment and storage medium". Technical Field

[0002] This disclosure relates to, but is not limited to, the field of communication technology, and in particular to a UE power-saving processing method, apparatus, communication device, and storage medium. Background Technology

[0003] New Radio (NR) employs carrier aggregation or dual-link technologies to significantly improve system transmission rates. Currently, User Equipment (UE) cells have three states: active, deactivated, and dormant. In dormant mode, the UE cell typically does not need to monitor the Physical Downlink Control Channel (PDCCH), but only needs to perform reference signal measurements and report Channel Quality Information (CQI) to synchronize the UE with the base station. However, current methods for measuring reference signals and reporting CQI in dormant mode are not energy-efficient. Summary of the Invention

[0004] This disclosure presents a UE power-saving processing method, apparatus, communication device, and storage medium.

[0005] According to a first aspect of the present disclosure, a UE power-saving processing method is provided, the method being executed by the UE, including:

[0006] In response to the UE switching its active bandwidth (BWP) in the first cell from the first BWP with downlink transmission scheduling to the second BWP without downlink transmission scheduling, the UE listens to the reference signal of the first cell on the second BWP.

[0007] When the signal power of the reference signal being monitored on the second BWP meets the relaxation measurement condition, the measurement of the reference signal of the UE on the second BWP is relaxed.

[0008] According to a second aspect of the present disclosure, a UE power-saving processing device is provided, applied to a UE, the device comprising:

[0009] The handover module is configured to switch from a first BWP with downlink transmission scheduling to a second BWP without downlink transmission scheduling in response to the UE's activated BWP in the first cell, and to listen to the reference signal of the first cell on the second BWP.

[0010] The processing module is configured to relax the measurement of the reference signal on the second BWP when the signal power of the reference signal being listened to on the second BWP meets the relaxation measurement conditions.

[0011] According to a third aspect of the present disclosure, a communication device is provided, comprising:

[0012] processor;

[0013] Memory used to store instructions executable by the storage processor;

[0014] The processor is configured to implement the UE power-saving processing method of any embodiment of this disclosure when running executable instructions.

[0015] According to a fourth aspect of the present disclosure, a computer storage medium is provided, wherein the computer storage medium stores a computer executable program, and when the executable program is executed by a processor, it implements the UE power-saving processing method of any embodiment of the present disclosure.

[0016] The technical solutions provided in this disclosure may have the following beneficial effects:

[0017] In this embodiment, the UE's active BWP in the first cell can be switched from a first BWP with downlink transmission scheduling to a second BWP without downlink transmission scheduling, and the UE can listen to the reference signal of the first cell on the second BWP. This eliminates the need for the UE to listen to downlink transmission scheduling in the first cell, thus saving UE power. Furthermore, if the signal power of the reference signal listened to by the UE on the second BWP meets the relaxation measurement condition, the measurement of the reference signal on the second BWP is relaxed; thus, by relaxing the measurement of the reference signal by the UE, the UE can further save power.

[0031] Please refer to Figure 1, which shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. As shown in Figure 1, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: a plurality of user equipment 110 and a plurality of base stations 120.

[0032] User equipment 110 can be a device that provides voice and / or data connectivity to a user. User equipment 110 can communicate with one or more core networks via a Radio Access Network (RAN). User equipment 110 can be an Internet of Things (IoT) user equipment, such as sensor devices, mobile phones (or "cellular" phones), and computers with IoT user equipment capabilities. 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, user agent, user device, or user equipment. Alternatively, user equipment 110 can also be a device from an unmanned aerial vehicle (UAV). Alternatively, user equipment 110 can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless user equipment connected to an external vehicle computer. Alternatively, user equipment 110 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0033] Base station 120 can be a network-side device in a wireless communication system. This wireless communication system can be a 4G system (also known as Long Term Evolution, LTE); or it can be a 5G system (also known as New Radio or 5G NR); or it can be the next generation after 5G. In this case, the access network in the 5G system can be called a New Generation-Radio Access Network (NG-RAN).

[0034] The base station 120 can be an evolved NB (eNB) used in a 4G system. Alternatively, the base station 120 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the base station 120 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Medium Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of the base station 120.

[0035] Base station 120 and user equipment 110 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0036] In some embodiments, user equipment 110 can also establish E2E (End to End) connections. Examples include vehicle-to-vehicle (V2V) communication, vehicle-to-infrastructure (V2I) communication, and vehicle-to-pedestrian (V2P) communication in vehicle-to-everything (V2X) communication.

[0037] Here, the user equipment mentioned above can be considered as the terminal equipment in the following embodiments.

[0038] In some embodiments, the wireless communication system described above may further include a network management device 130.

[0039] Several base stations 120 are connected to network management device 130. Network management device 130 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation of network management device 130 is not limited in this embodiment.

[0040] As shown in Figure 2, a UE power-saving processing method is provided. The method is executed by the UE and includes:

[0041] Step S21: In response to the UE's activation of the BWP in the first cell, the UE switches from the first BWP with downlink transmission scheduling to the second BWP without downlink transmission scheduling, and listens for the reference signal of the first cell on the second BWP.

[0042] Step S22: In response to the signal power of the reference signal being monitored on the second BWP satisfying the relax measurement condition, relax the measurement of the reference signal on the second BWP by the UE. In one embodiment, the UE can be various mobile terminals or fixed terminals. For example, the UE can be, but is not limited to, a mobile phone, computer, server, wearable device, game control platform, or multimedia device, etc.

[0043] In one embodiment, the UE is a disconnected UE. The disconnected UE includes: a Radio Resource Control (RRC) idle UE and / or an RRC inactive UE.

[0044] In one embodiment, relaxing the measurement of the reference signal of the UE on the second BWP in step S22 can be: reducing the measurement requirements of the reference signal of the UE on the second BWP.

[0045] For example, relaxing the measurement of the reference signal of the UE on the second BWP can be achieved by increasing the measurement period of the reference signal on the second BWP. In this way, by increasing the measurement period of the reference signal on the second BWP, the measurement requirements of the reference signal of the UE on the second BWP can be reduced, thereby relaxing the measurement of the reference signal of the UE on the second BWP.

[0046] For example, the measurement of the reference signal transmitted by the UE on the second BWP can also be achieved by reducing the number of sample values ​​of the reference signal measured by the UE in a single measurement on the second BWP. In this way, by reducing the number of sample values ​​of the reference signal measured on the second BWP each time, the measurement requirements of the reference signal of the UE on the second BWP can be reduced, thereby relaxing the measurement of the reference signal of the UE on the second BWP.

[0047] Of course, in other embodiments, relaxing the measurement of the reference signal on the second BWP can also be achieved by any other method of reducing the measurement requirements of the UE's reference signal on the second BWP; for example, it can also be by reducing the measurement of the UE's reference signal on the second BWP, etc. There are no restrictions on the specific method of reducing the measurement requirements of the UE's reference signal on the second BWP.

[0048] In one embodiment, the first cell includes either a primary cell or a secondary cell.

[0049] In this embodiment of the disclosure, the cell where the UE is located can be a primary cell and at least one secondary cell. The bandwidth occupied by a primary cell can be divided into one or more BWPs; or, the bandwidth occupied by a secondary cell can be divided into one or more BWPs. For example, in one embodiment, the bandwidth occupied by the first cell includes at least: a first BWP and a second BWP.

[0050] In one embodiment, the first cell is a secondary cell. In some cases, the DCI of the secondary cell can be transmitted by the primary cell. In this case, after the UE switches from the first BWP to the second BWP, since the DCI of the secondary cell can be received on the primary cell, the loss of the DCI transmitted by the cell can be minimized while saving power.

[0051] In one embodiment, if the UE switches its currently active BWP in the first cell from the first BWP to the second BWP, the UE changes from an active state to a dormant state in the first cell. In one embodiment, the activated BWP can be the UE's currently active BWP.

[0052] In one embodiment, the downlink transmission includes, but is not limited to, at least one of the following:

[0053] Physical Downlink Control Channel (PDCCH) transmission;

[0054] Physical Downlink Shared Channel (PDSCH) transmission.

[0055] For example, the UE's active BWP in the first cell switches from a first BWP with PDCCH transmission scheduling to a second BWP without PDCCH transmission scheduling, and listens for the reference signal on the second BWP. Thus, in this embodiment of the disclosure, the UE does not have PDCCH transmission scheduling when listening for the reference signal on the second BWP, which can save the UE's power consumption.

[0056] For example, the UE's active BWP in the first cell switches from a first BWP with PDSCH transmission scheduling to a second BWP without PDSCH transmission scheduling, and listens for the reference signal on the second BWP. Thus, in this embodiment of the disclosure, the UE does not have PDSCH transmission scheduling when listening for the reference signal on the second BWP, which can save the UE's power consumption.

[0057] For example, the UE's active BWP in the first cell is switched from a first BWP with PDCCH and / or PDSCH transmission scheduling to a second BWP without PDCCH and / or PDSCH scheduling, and the UE listens for the reference signal on the second BWP. Thus, in this embodiment of the disclosure, the UE does not have PDSCH and PDCCH transmission scheduling when listening for the reference signal on the second BWP, which can save the UE's power consumption.

[0058] In one embodiment, the reference signal includes, but is preferably, at least one of the following:

[0059] Synchronization Signal Block (SSB);

[0060] Channel State Information Reference Signal (CSI-RS).

[0061] In one embodiment, the signal power of the reference signal listened to on the second BWP satisfies the relaxation measurement condition, including:

[0062] The signal power of the reference signal monitored on the second BWP is greater than the threshold value, and the signal power of the reference signal monitored on the second BWP satisfies the relaxation measurement condition.

[0063] In one embodiment, the signal power of the reference signal being monitored on the second BWP is greater than a threshold value, including but not limited to at least one of the following:

[0064] The signal power of the SSB monitored on the second BWP is greater than the SSB threshold.

[0065] The signal power of the CSI-RS monitored on the second BWP is greater than the CSI-RS threshold.

[0066] In this embodiment of the disclosure, if the signal power of the SSB is greater than the SSB threshold, it is determined that the signal quality of the SSB is relatively good. This reduces the measurement of the SSB and allows the UE to successfully know the channel condition information based on the current measurement or not lose synchronization with the first cell. This relaxes the measurement of the SSB on the second BWP, thereby further saving the power consumption of the UE.

[0067] If the signal power of CSI-RS is greater than the CSI-RS threshold, it is determined that the signal quality of CSI-RS is relatively good. Reducing the measurement of CSI-RS can also enable the UE to successfully know the channel status information based on the current measurement or not lose synchronization with the first cell. In this way, the UE can relax the measurement on CSI-RS, thereby further saving the UE's power consumption.

[0068] In this embodiment, the UE's active BWP in the first cell can be switched from a first BWP with downlink transmission scheduling to a second BWP without downlink transmission scheduling, and the UE can listen to the reference signal of the first cell on the second BWP. This eliminates the need for the UE to listen to downlink transmission scheduling in the first cell, thereby saving UE power. Furthermore, if the signal power of the reference signal listened to by the UE on the second BWP meets the relaxation measurement condition, the measurement of the reference signal on the second BWP is relaxed; thus, by relaxing the measurement of the reference signal by the UE, the UE can further save power.

[0069] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0070] As shown in Figure 3, a UE power-saving processing method is provided, which is executed by the UE and includes:

[0071] Step S31: In response to the SSB reference signal received power RSRP being monitored on the second BWP being greater than the SSB threshold, relax the measurement of the SSB on the second BWP by the UE; and / or, in response to the CSI-RS being monitored on the second BWP being greater than the CSI-RS threshold, relax the measurement of the CSI-RS on the second BWP by the UE.

[0072] In some embodiments of this disclosure, the first BWP is the first BWP described in step S21, and the second BWP is the second BWP described in step S21.

[0073] In some embodiments, relaxing the measurement of the reference signal of the UE on the second BWP includes at least one of the following:

[0074] The UE increases the measurement period of the reference signal in the second BWP measurement;

[0075] Reduce the number of sample values ​​measured by the UE when measuring the reference signal in a single measurement of the second BWP.

[0076] This disclosure provides a UE power-saving processing method, executed by the UE, comprising: in response to the RSRP of an SSB monitored on a second BWP being greater than an SSB threshold value, the UE measures the SSB on the second BWP according to an increased SSB measurement period.

[0077] In one embodiment, the increased SSB measurement period is N times the previous SSB measurement period, where N is greater than 1.

[0078] For example, the BWP of the UE's first cell includes at least: a first BWP and a second BWP; wherein, the first BWP is a BWP with downlink transmission scheduling, and the second BWP is a BWP without downlink transmission scheduling; the second BWP of the UE in the first cell listens for SSB signals. In response to the UE detecting that the RSRP of the SSB detected by the second BWP is greater than the SSB threshold, the UE determines to increase the SSB measurement period T1 to N×T1, and performs SSB measurement based on the N×T1 SSB measurement period. Here, N can be any value greater than 1; for example, N can be an integer greater than 1, etc.

[0079] Thus, in this embodiment of the disclosure, the UE can perform SSB measurement based on an increased SSB measurement period; thus, SSB measurement can be performed based on a relatively longer time interval, which can greatly save the UE's power consumption.

[0080] This disclosure provides a UE power-saving processing method, executed by the UE, comprising: in response to the RSRP of the CSI-RS monitored on the second BWP being greater than the CSI-RS threshold, the UE measuring the CSI-RS on the second BWP according to an increased CSI-RS measurement period.

[0081] In one embodiment, the increased CSI-RS measurement period is M times the previous CSI-RS measurement period, where M is greater than 1.

[0082] For example, the BWP of the UE's first cell includes at least: a first BWP and a second BWP; wherein, the first BWP is a BWP with downlink transmission scheduling, and the second BWP is a BWP without downlink transmission scheduling; the second BWP of the UE in the first cell listens for SSB signals. In response to the UE detecting that the RSRP of CSI-RS is greater than the CSI-RS threshold value at the second BWP, the UE determines to increase the CSI-RS measurement period T2 to M×T2, and performs CSI-RS measurement based on the M×T2 CSI-RS measurement period. Here, M can be any value greater than 1, for example, M can be an integer greater than 1.

[0083] Thus, in this embodiment of the disclosure, the UE can perform CSI-RS measurements based on an increased CSI-RS measurement period; thus, CSI-RS measurements can be performed based on a relatively longer time interval, which can greatly save the UE's power consumption.

[0084] This disclosure provides a UE power-saving processing method, executed by the UE, including: in response to the RSRP of an SSB monitored on a second BWP being greater than an SSB threshold value, reducing the number of sample values ​​measured by the UE when measuring an SSB in a single measurement on the second BWP.

[0085] For example, the BWP of the UE's first cell includes at least: a first BWP and a second BWP; wherein, the first BWP is a BWP with downlink transmission scheduling, and the second BWP is a BWP without downlink transmission scheduling; the second BWP in the first cell listens for SSB signals. In response to the UE detecting that the RSRP of the SSB heard by the second BWP is greater than the SSB threshold, the UE determines that the number of sample values ​​measured in a single BBS measurement by the second BWP is reduced from P1 to P2. Here, P2 is less than P1.

[0086] Thus, in this embodiment of the disclosure, since the number of sample values ​​measured in a single SSB measurement is reduced, the power consumption of the UE can also be saved.

[0087] This disclosure provides a UE power-saving processing method, executed by the UE, including: in response to the RSRP of the CSI-RS monitored on the second BWP being greater than the CSI-RS threshold, reducing the number of sample values ​​measured by the UE in a single CSI-RS measurement on the second BWP.

[0088] For example, the BWP of the UE's first cell includes at least: a first BWP and a second BWP; wherein, the first BWP is a BWP with downlink transmission scheduling, and the second BWP is a BWP without downlink transmission scheduling; the second BWP of the UE in the first cell listens for SSB signals. In response to the UE detecting that the RSRP of the SSB heard by the second BWP is greater than the CSI-RS threshold, the UE determines that the number of sample values ​​measured in a single CSI-RS measurement by the second BWP is reduced from Q1 to Q2. Here, Q2 is less than Q1.

[0089] Thus, in this embodiment of the disclosure, since the number of sample values ​​measured in a single CSI-RS measurement is reduced, the power consumption of the UE can also be saved.

[0090] In some embodiments, step S22 includes at least one of the following:

[0091] In response to the reference signal received power RSRP of the SSB being listened to on the second BWP being greater than the SSB threshold, the measurement of the SSB on the second BWP of the UE is relaxed.

[0092] In response to the RSRP of the CSI-RS monitored on the second BWP being greater than the CSI-RS threshold, the measurement of CSI-RS on the second BWP by the UE is relaxed.

[0093] In some embodiments, step S22 may also include, but is not limited to, at least one of the following:

[0094] In response to the RSRP of the SSB monitored on the second BWP being greater than the SSB threshold, the UE performs SSB measurement on the second BWP based on the increased SSB measurement period and the reduced number of sample values ​​measured per SSB measurement.

[0095] In response to the fact that the RSRP of the CSI-RS monitored on the second BWP is greater than the threshold value of the CSI-RS, the UE performs CSI-RS measurement on the second BWP according to the increased CSI-RS measurement period and the reduced number of sample values ​​measured in a single CSI-RS measurement.

[0096] Thus, in this embodiment of the present disclosure, the measurement period of the reference signal can be increased simultaneously, and the number of sample values ​​measured in a single measurement of the reference signal can be reduced; thus, the power consumption of the UE can be greatly reduced.

[0097] In this embodiment, the UE can determine that the reference signal quality is relatively good when the RSRP of the reference signal being monitored on the second BWP is greater than a threshold value, for example, when the RSRP of the monitored SSB is greater than the SSB threshold value and / or the RSRP of the monitored CSI-RS is greater than the CSI-RS threshold value. This allows the UE to relax the measurement of the reference signal by increasing the measurement period or reducing the number of sample values ​​measured in a single measurement. This relaxation of the reference signal measurement also allows the UE to successfully understand the channel status based on the current measurement or to avoid losing synchronization with the first cell. Thus, this embodiment saves the UE's power consumption by relaxing the measurement of the reference signal on the second BWP.

[0098] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0099] As shown in Figure 4, this embodiment of the present disclosure provides a UE power-saving processing method, executed by the UE, including:

[0100] Step S41: Receive the Serving Cell Configuration (ServingCellConfig) signaling sent by the base station, wherein the ServingCellConfig signaling carries a threshold value.

[0101] In one embodiment, the threshold values ​​include: SSB threshold value and / or CSI-RS threshold value.

[0102] In some embodiments of this disclosure, the SSB threshold value is the SSB threshold value described in step S31, and the CSI-RS threshold value is the threshold value described in step S31.

[0103] In other embodiments, step S41 above may be: receiving higher-layer signaling sent by the base station, wherein the higher-layer signaling carries a threshold value; or, step S41 above may be: receiving RRC signaling sent by the base station, wherein the RRC signaling carries a threshold value.

[0104] This disclosure provides a UE power saving processing method, executed by the UE, including: obtaining SSB threshold value and / or CSI-RS threshold value.

[0105] For example, the UE receives serving cell configuration signaling sent by the base station, wherein the serving cell configuration signaling carries an SSB threshold value and / or a CSI-RS threshold value.

[0106] For example, the UE pre-configures SSB threshold values ​​and / or CSI-RS threshold values. For instance, the UE pre-configures SSB threshold values ​​and / or CSI-RS threshold values ​​in response to user input.

[0107] For example, the UE determines the SSB threshold and / or CSI-RS threshold based on historical data. For instance, the UE determines the current SSB threshold based on historically saved SSB thresholds; and / or, the UE determines the current CSI-RS threshold based on historically saved CSI-RS thresholds.

[0108] In this embodiment of the disclosure, the UE can obtain threshold values, such as the SSB threshold value and / or CSI-RS threshold value, by receiving serving cell configuration signaling sent by the base station; thereby facilitating the UE to determine whether the UE meets the relaxation measurement conditions. Furthermore, this embodiment of the disclosure can send threshold values ​​based on serving cell configuration signaling, which can improve the utilization rate of serving cell configuration signaling.

[0109] Furthermore, this disclosure also provides multiple methods for obtaining SSB threshold values ​​and / or CSI-RS threshold values, applicable to more application scenarios for obtaining threshold values.

[0110] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0111] As shown in Figure 5, a UE power-saving processing method is provided, which is executed by the UE and includes:

[0112] Step S51: Receive downlink control information (DCI) sent by the base station, wherein the DCI carries indication information;

[0113] Step S52: Based on the indication information, the UE switches the active BWP in the first cell from the first BWP to the second BWP.

[0114] In some embodiments of this disclosure, the first BWP is the first BWP described in step S21, and the second BWP is the second BWP described in step S21.

[0115] The information here is used to instruct the UE to switch from the first BWP to the second BWP.

[0116] In one embodiment, the DCI can be DCI format 1. For example, indication information is carried in a predetermined information field of DCI format 1. Of course, in other embodiments, the DCI can be any other implementable DCI format, such as DCI format 1A, DCI format 1B, DCI format 2, or DCI format 2B, etc.

[0117] In one embodiment, step S51 includes: receiving a DCI sent by the base station in response to the UE's active BWP in the first cell being the first BWP. Thus, in this embodiment of the disclosure, since the currently working BWP (i.e., the active BWP) is the first BWP, and the first BWP is a BWP with downlink transmission scheduling, the DCI sent by the base station can be received at this time, thereby obtaining indication information based on the DCI.

[0118] In this embodiment of the disclosure, the UE can perform a BWP handover based on the DCI carrying indication information sent by the base station, switching from a first BWP operating with downlink transmission to a second BWP operating without downlink transmission. In this way, the UE does not need to listen to PDCCH and / or PDSCH, thus saving power consumption.

[0119] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0120] This disclosure provides a UE power-saving processing method, executed by the UE, which may include: in response to the fact that the signal power of the reference signal being monitored on the second BWP does not meet the relaxation measurement conditions, not relaxing the measurement of the reference signal on the second BWP.

[0121] This disclosure provides a UE power-saving processing method, executed by the UE, which may include: in response to the RSRP of the SSB being monitored on the second BWP being less than or equal to the SSB threshold value, the UE maintains the original measurement cycle on the second BWP to measure the reference signal.

[0122] For example, the BWP of the UE's first cell includes at least: a first BWP and a second BWP; wherein, the first BWP is a BWP with downlink transmission scheduling, and the second BWP is a BWP without downlink transmission scheduling; the second BWP of the UE in the first cell listens for SSB signals. At a first moment, in response to the UE detecting that the RSRP of the SSB detected by the second BWP is greater than the SSB threshold, the UE determines to increase the SSB measurement period T1 to N×T1, and performs SSB measurement based on the N×T1 SSB measurement period. Here, N can be any value greater than 1; for example, N can be 1.2, 2, 2.5, or 3, etc. At a second moment, in response to the UE detecting that the RSRP of the SSB detected by the second BWP is less than or equal to the SSB threshold, the UE determines to restore the SSB measurement period to the original measurement period T1, and performs SSB measurement based on the T1 SSB measurement period.

[0123] Thus, in this embodiment, since the RSRP of the SSB is less than or equal to the SSB threshold, indicating that the current SSB signal quality is not very good, relatively frequent SSB monitoring can still be used. However, since the UE is monitoring on the second BWP and does not need to monitor downlink transmission scheduling, the UE's power consumption can be saved to a certain extent.

[0124] This disclosure provides a UE power-saving processing method, executed by the UE, which may include: in response to the RSRP of the CSI-RS monitored on the second BWP being less than or equal to the CSI-RS threshold value, the UE maintains the original measurement cycle to perform CSI-RS measurement on the second BWP.

[0125] For example, the BWP of the UE's first cell includes at least: a first BWP and a second BWP; wherein, the first BWP is a BWP with downlink transmission scheduling, and the second BWP is a BWP without downlink transmission scheduling; the second BWP of the UE in the first cell listens for SSB signals. At a first moment, in response to the UE detecting that the RSRP of CSI-RS is greater than the CSI-RS threshold value at the second BWP, the UE determines to increase the CSI-RS measurement period T1 to M×T2, and performs CSI-RS measurement based on the CSI-RS measurement period of M×T2. Here, M can be any value greater than 1; for example, N can be 1.2, 2, 2.5, or 3, etc. At a second moment, in response to the UE detecting that the RSRP of CSI-RS is less than or equal to the CSI-RS threshold value at the second BWP, the UE determines to restore the CSI-RS measurement period to the original measurement period T2, and performs CSI-RS measurement based on the CSI-RS measurement period of T2.

[0126] Thus, in this embodiment of the disclosure, since the RSRP of the detected CSI-RS is less than or equal to the CSI-RS threshold, it is determined that the current CSI-RS signal quality is not very good, so relatively frequent CSI-RS monitoring can still be used. However, since the UE is monitoring on the second BWP, there is no need to monitor downlink transmission scheduling, which can also save the UE's power consumption to a certain extent.

[0127] In some embodiments, when the signal power of the reference signal being listened to on the second BWP does not meet the relaxation measurement condition, the measurement of the reference signal of the UE on the second BWP is not relaxed, including at least one of the following:

[0128] In response to the RSRP of the SSB being monitored on the second BWP being less than or equal to the SSB threshold value, the UE continues to measure the SSB on the second BWP using the original measurement cycle.

[0129] In response to the RSRP of CSI-RS being monitored on the second BWP being less than or equal to the CSI-RS threshold, the UE continues to perform CSI-RS measurements on the second BWP using the original measurement cycle.

[0130] In this embodiment, when the RSRP of the reference signal monitored by the UE on the second BWP is less than or equal to a threshold value, it is determined that the signal power of the reference signal does not meet the relaxation measurement condition, and therefore the measurement of the reference signal on the second BWP is not relaxed. In this way, even when the signal quality of the reference signal is not very good, the reference signal can be measured according to a relatively dense measurement cycle, ensuring accurate measurement of the reference signal and achieving transmission synchronization between the base station and the UE's first cell. Furthermore, since this application performs the reference signal measurement on the second BWP, there is no need to monitor downlink transmission scheduling, which can also save UE power consumption to some extent.

[0131] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0132] To further explain any embodiment of this disclosure, the following example is provided for illustration:

[0133] Example 1

[0134] As shown in Figure 6, this embodiment of the present disclosure provides a UE power-saving processing method, which is executed by the UE and includes the following steps:

[0135] Step S61: In response to the UE's activation of the BWP in the secondary cell as the first BWP with downlink transmission scheduling, receive the DCI carrying indication information;

[0136] In one embodiment, in response to the fact that the BWP currently operating in the secondary cell is a first BWP with PDCCH and / or PDSCH scheduling, the UE receives a DCI sent by the base station based on PDCCH and / or PDSCH; wherein the DCI carries indication information; wherein the indication information is used to indicate that the BWP currently operating in the UE is switched from the first BWP to the second BWP; wherein the second BWP is a BWP without downlink transmission scheduling.

[0137] Step S62: Based on the indication information, the UE's active BWP in the secondary cell is switched from the first BWP to the second BWP without downlink transmission scheduling;

[0138] In one embodiment, based on indication information, the UE switches the BWP currently operating in the secondary cell from the first BWP with PDCCH and / or PDSCH scheduling to the second BWP without PDCCH and / or PDSCH scheduling.

[0139] Step S63: Receive the serving cell configuration signaling sent by the base station, wherein the serving cell configuration signaling carries a threshold value;

[0140] In one embodiment, the UE receives serving cell configuration signaling sent by the base station, wherein the serving cell configuration signaling carries an SSB threshold value and / or a CSI-RS threshold value.

[0141] Step S64: The power signal of the reference signal being monitored on the second BWP;

[0142] In one embodiment, the UE listens to the RSRP of the SSB on the second BWP according to the SSB measurement period T1; and / or listens to the RSRP of the CSI-RS according to the CSI-RS measurement period T2.

[0143] Step S65: In response to the signal power of the reference signal being monitored on the second BWP satisfying the relaxation measurement condition, relax the measurement of the reference signal of the UE on the second BWP;

[0144] In one embodiment, if the RSRP of the SSB monitored by the UE on the second BWP is greater than the SSB threshold, the SSB measurement period T1 is increased to N×T1, and the SSB is measured on the second BWP according to the SSB measurement period of N×T1; and / or, if the RSRP of the CSI-RS monitored by the UE on the second BWP is greater than the CSI-RS threshold, the CSI-RS measurement period T2 is increased to M×T2, and the CSI-RS is measured on the second BWP according to the measurement period of M×T2.

[0145] Step S66: In response to the fact that the signal power of the reference signal being monitored on the second BWP does not meet the relaxation measurement condition, the measurement of the reference signal on the second BWP by the UE is not relaxed. In one embodiment, if the RSRP of the SSB being monitored by the UE on the second BWP is less than or equal to the SSB threshold value, the SSB measurement period is restored from N×T1 to T1, and the SSB is measured on the second BWP according to the SSB measurement period T1; and / or, if the RSRP of the CSI-RS being monitored by the UE on the second BWP is less than or equal to the CSI-RS threshold value, the CSI-RS measurement period is restored from M×T2 to T2, and the CSI-RS is measured on the second BWP according to the CSI-RS measurement period T2.

[0146] In this embodiment of the disclosure, when the UE is operating in the first BWP of the secondary cell with downlink transmission scheduling, it can receive DCI carrying indication information and switch the currently operating BWP of the secondary cell from the first BWP with downlink transmission scheduling to the second BWP without downlink transmission scheduling based on the indication information. In this way, the UE can listen to the reference signal in the second BWP of the secondary cell without downlink transmission scheduling, thereby saving the UE's power consumption.

[0147] Furthermore, in this embodiment, if the UE detects a reference signal power greater than a threshold value in the second BWP of the secondary cell, for example, when the RSRP of the SSB is greater than the SSB threshold value and / or the RSRP of the CSI-RS is greater than the CSI-RS threshold value, it is determined that the signal quality of the SSB and / or CSI-RS is relatively good at this time. Thus, a relatively large measurement period can be used to measure the SSB and / or CSI-RS, thereby further saving the UE's power consumption.

[0148] Furthermore, in this embodiment, if the UE detects a reference signal power less than or equal to a threshold value in the second BWP of the secondary cell, for example, if the RSRP of the SSB is less than or equal to the SSB threshold value, and / or the RSRP of the CSI-RS is less than or equal to the CSI-RS threshold value, it is determined that the signal quality of the SSB and / or CSI-RS is not very good at this time. Thus, relatively frequent measurement cycles can be used to measure the SSB and / or CSI-RS, thereby ensuring that the SSB and / or CSI-RS are detected, achieving synchronous transmission between the base station and the UE.

[0149] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.
