Abstract
Description
Technical Field
[0001] The present application relates to the field of wireless communication technology, and in particular to a signal measurement method and related devices. Background Art
[0002] The design and development of the fifth generation (5G) mobile communication system targets mobile phones and vertical use cases. In addition to latency, reliability, and feasibility, user equipment (UE) energy efficiency is also critical to 5G. Currently, 5G devices may need to be charged weekly or daily, depending on individual usage time. Generally speaking, 5G devices consume tens of milliwatts in the idle / inactive state of radio resource control (RRC) and hundreds of milliwatts in the RRC connected state. Designing for extended battery life is a prerequisite for improving energy efficiency and a better user experience.
[0003] Energy efficiency is even more critical for UEs without continuous power sources, such as those using small rechargeable batteries and single-coin batteries. In vertical use cases, sensors and actuators are widely deployed for monitoring, measurement, and charging. Their batteries are typically non-rechargeable and expected to last for at least several years. In some IoT scenarios, wearable devices such as smartwatches, rings, electronic health devices, and medical monitoring equipment face challenges maintaining performance while maintaining a battery life of one to two weeks at typical battery capacities.
[0004] Power consumption depends on the configured wake-up cycle length. For example, in the RRC idle state, power consumption depends on the configured paging cycle. A longer paging cycle means the UE will spend more time in sleep mode, which results in energy savings. To meet the aforementioned battery life requirements, it is expected that a high-value extended discontinuous reception (eDRX) cycle will be used, with a large value. However, while using eDRX to achieve higher energy efficiency, it also results in higher latency, making it unsuitable for services that require both long battery life and low latency. For example, in a fire detection and extinguishing use case, fire shutters should be closed and actuators should activate fire sprinklers within 1-2 seconds after a sensor detects a fire. A longer eDRX cycle would not meet the latency requirements. eDRX is clearly not suitable for scenarios with high latency requirements. Therefore, research on technologies that can support both ultra-low power consumption mechanisms and ultra-low latency is crucial.
[0005] Currently, UEs need to wake up periodically during each discontinuous reception (DRX) cycle. When a UE is awake but no signaling or data services are being transmitted during the awake period, it is considered an invalid awake state, and the power consumption during this period dominates the UE's overall power consumption. If the UE wakes up only when signaling or data services are required, such as when receiving its own paging message, the UE's power consumption can be significantly reduced. This energy saving is also an important means of further improving the user experience.
[0006] Higher energy savings can be achieved by using a wake-up signal to trigger the main receiver and a separate receiver with ultra-low power monitoring wake-up signal capability. The main receiver is used for data transmission and reception and can be turned off or set to deep sleep unless turned on. The power consumption of monitoring the wake-up signal depends on the wake-up signal design and the hardware modules of the wake-up receiver for signal detection and processing. The research should mainly focus on low power wake-up signals (LP-WUS) / low power wake-up receivers (LP-WUR) for power-sensitive, small devices, including IoT use cases (such as industrial sensors, controllers) and wearable devices. It can also be used in other scenarios, such as extended reality (XR) / smart glasses, and smartphones.
[0007] Measurement is one of the contents of the radio resource management (RMM) function, and its purpose is to monitor the communication quality of the UE's serving cell and / or neighboring cells in real time, so that when the signal quality of the serving cell deteriorates to a certain extent, the UE's serving cell is changed by switching (RRC connected state) or cell selection / reselection (RRC idle state and RRC inactive state) to ensure the continuity of UE services. The NR network can configure the UE to perform two types of NR measurements, including same-frequency measurement and different-frequency measurement. When both LP-WUR and the main receiver are deployed in the UE, how to set the different-frequency measurement rules to achieve better communication and energy saving effects is an urgent problem to be solved. Summary of the Invention

[0013] In an embodiment of the present application, the status of the measurement interval is judged based on whether there is data transmission indicated by LP-WUS, whether the index parameter of the same-frequency measurement is greater than the first threshold value, and whether the network device indicates that a measurement interval needs to be configured for measurement. While taking into account the signal quality of the same-frequency measurement, whether the different-frequency measurement will affect the data transmission and the demand indication of the network device are taken into account, thereby further improving the reliability of determining the status of the measurement interval and applying it to the different-frequency measurement, thereby improving the communication quality of the terminal device.

[0104] In addition, the network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.
[0105] The following is an introduction to the prior art of the embodiments of the present application.
[0106] See also Figure 2A , Figure 2A A schematic diagram of the structure of a terminal device provided in an embodiment of the present application is shown in FIG. Figure 2A As shown, the terminal device includes an LP-WUR and a major receiver (MR). The MR is used for wireless communication, and the LP-WUR is used to perform some low-power operations when there is no signal transmission. For example, it can measure cell signals or monitor the LP-WUS to trigger the MR to wake up.
[0107] For monitoring of LP-WUS process, please refer to Figure 2B , Figure 2B A flow chart for monitoring LP-WUS is provided in an embodiment of the present application, such as Figure 2BAs shown, the LP-WUR in the terminal device is in the ON state. When the LP-WUR receives the LP-WUS, it determines whether the LP-WUS indicates to wake up the MR. If it is (Y), and assuming the MR is in the dormant or OFF state, the MR switches from the dormant state to the ON state. If the MR is in the ON state, the MR remains in the ON state. If the LP-WUS does not indicate (N) to wake up the MR, and assuming the MR is in the dormant or OFF state, the MR remains in the dormant or OFF state. If the MR is in the ON state, it switches to the dormant or OFF state.
[0108] New radio (NR) networks can configure terminal devices to perform two types of NR measurements: intra-frequency and inter-frequency measurements. Intra-frequency measurements occur when the terminal device's current cell and the target cell to be measured are on the same carrier frequency (center frequency). Inter-frequency measurements occur when the terminal device's current cell and the target cell are on different carrier frequencies (center frequencies).
[0109] If a terminal device needs to perform inter-frequency measurements (including inter-standard measurements), a simple approach is to install two RF receivers in the terminal device, one to measure the frequency of the local cell and the other to measure the frequency of the target cell. However, this increases costs and can cause interference between the different frequencies. Therefore, the 3rd Generation Partnership Project (3GPP) proposed a measurement gap (GAP). This reserves a certain period of time (the GAP time) during which the terminal device does not send or receive any data. Instead, it tunes the receiver to the target cell frequency to perform inter-frequency measurements. When the GAP time expires, the receiver switches back to the current cell.
[0110] See Figure 2C , Figure 2C A schematic diagram of a measurement interval provided in an embodiment of the present application, as shown in the figure, the essence of the measurement interval is to prohibit data transmission and reception during the GAP time, and to transmit and receive data outside the GAP time.
[0111] In some cases, GAP is also required for same-frequency measurements in addition to the following:
[0112] 1. The synchronization signal / physical broadcast channel (SS / PBCH) block (SSB) is activated and fully contained within the downlink (DL) bandwidth part (BWP). Therefore, the terminal device can receive both data and SSB simultaneously without making any radio frequency (RF) adjustments.
[0113] 2. The activated DL BWP is the initial BWP (so the BWP is equal to the bandwidth of CORESET#0). The implicit premise is that the measured SSB is the cell defining (CD) SSB. At this time, the terminal device needs to be able to receive CORESET#0 and SSB at the same time.
[0114] 3. The terminal device supports the RRC based GAP requirement (based NeedForGap) reporting feature of Rel-16 and informs the network that the same-frequency measurement does not require a measurement gap.
[0115] In addition, in some scenarios, different measurements have priorities. For example, the terminal device's positioning measurement has a higher priority, or the terminal device receives positioning reference signals at different frequencies. In these scenarios, positioning measurements also require GAP assistance.
[0116] NR needs to meet certain criteria before performing inter-frequency measurement. The criteria are Srxlev≤SnonIntraSearchP, or Squal≤SnonIntraSearchQ. Among them, Srxlev represents the index parameter of reference signal received power (RSRP) (or the signal quality indicated by RSRP), and Squal represents the index parameter of reference signal receiving quality (RSRQ) (or the signal quality indicated by RSRQ). SnonIntraSearchP represents the threshold value corresponding to the index parameter of RSRP, and SnonIntraSearchQ represents the threshold value corresponding to the index parameter of RSRQ. Among them, the parameters used to calculate Srxlev and Squal can be carried by system information block 1 (SIB1). When the terminal device decodes SIB1, the value of Srxlev or Squal can be obtained. The thresholds SnonIntraSearchP and SnonIntraSearchQ are carried by SIB2. The terminal device can determine whether it is necessary to start inter-frequency measurement by judging the size of the received information and the threshold.
[0117] When the terminal equipment includes both LP-WUR and MR, it becomes a problem as to who will perform the inter-frequency measurement and who will perform the same-frequency measurement.
[0118] As a low-power receiver, LP-WUR can implement more functions to achieve energy-saving effects on terminal equipment. For example, LP-WUR is used to receive paging messages LP-WUS, or LP-WUR can be used to receive synchronization signals for synchronization and / or measurement processes. The synchronization signal can be the SSB existing in the NR system, or it can be a redesigned synchronization signal, such as a low-power synchronization signal based on on-off keying (OOK), or a low-power synchronization signal based on frequency shift keying (FSK), or a low-power synchronization signal based on orthogonal frequency-division multiplexing (OFDM), or a low-power synchronization signal based on the fusion of the above-mentioned different modulation methods. The fusion scheme includes the fusion of OOK and OFDM, as well as the fusion of FSK and OFDM. OOK modulation has some symbols that send signals and some symbols that do not. The fusion scheme of OOK and OFDM is: OFDM is used for modulation on the symbols that send OOK signals, that is, the signal part of OOK can carry more information. A common solution is to use different sequences, such as the ZC sequence, to distinguish different terminal devices during the OOK signal portion. This can increase the data rate of signal transmission and improve signal detection performance.
[0119] In short, LP-WUR can at least perform intra-frequency measurements or measurements of the serving cell. For inter-frequency measurements, due to the low power design of LP-WUR, the main receiver can be woken up for inter-frequency measurements.
[0120] In some cases, when the RSRP or RSRQ measured by LP-WUR is greater than a certain threshold value, the main receiver can be awakened to perform heterofrequency measurement. The calculation method of the RSRP threshold value can refer to the above description, and is obtained according to the parameters carried by SIB2. However, for the terminal device of the embodiment of the present application, in addition to considering the problem that MR needs to be turned on for heterofrequency measurement due to poor signal quality, it is also necessary to consider whether MR needs to be turned on for data transmission and reception, and the impact that LP-WUS may have on the communication process of LP-WUR. Therefore, the criteria for NR to start heterofrequency measurement are not applicable to the terminal device in the embodiment of the present application. The rules for GAP to take effect and turn on MR for heterofrequency measurement need to be redefined.
[0121] Based on this, an embodiment of the present application provides a method for signal measurement. The processing described below as being performed by a single execution subject may also be divided into being performed by multiple execution subjects, and these execution subjects may be logically and / or physically separated. For example, the processing performed by the network device may be divided into being performed by at least one of the CU, DU, and RU. Figure 3A , Figure 3A A flow chart of a signal measurement method provided in an embodiment of the present application is applied to a first device, wherein the first device includes a main receiver MR and a low power wake-up receiver LP-WUR, such as Figure 3A As shown, the method includes the following process:
[0122] 201. Perform co-frequency measurement by waking up the receiver with low power consumption.
[0123] The first device can be any terminal device described above, and the terminal device includes MR and LP-WUR (supports LP-WUS features), for details, please refer to Figure 2A The first device performs co-frequency measurement through LP-WUR, which is used by the terminal device to select, reselect or switch cells. While performing co-frequency measurement through LP-WUR, LP-WUS can also be received through LP-WUR, and the information in LP-WUS indicates whether there is data transmission. When LP-WUS indicates that there is data transmission, LP-WUR can be used to trigger the awakening of MR for data transmission and reception. When there is no data or signaling transmission and reception, MR can be in a closed or dormant state.
[0124] 202. When it is determined that the state of the measurement interval is in an effective state, heterofrequency measurement is performed through the main receiver within the measurement interval; wherein the state of the measurement interval is determined based on a first condition, and the first condition includes the following information: whether the low-power wake-up signal indicates that there will be data transmission, and whether the indicator parameter of the same-frequency measurement is greater than the first threshold value.
[0125] Typically, in order to avoid affecting the data transmission and reception of the first device, the first device only performs inter-frequency measurements within the measurement interval. Therefore, when determining whether the measurement interval is effective, it is necessary to consider the needs of the terminal device for transmitting and receiving data while considering the communication quality of the terminal device. Therefore, in an embodiment of the present application, whether the measurement interval is effective is determined based on the first condition, and the first condition includes the following information:
[0126] (1) The low power wake-up signal LP-WUS indicates whether there is data transmission.
[0127] (2) Whether the index parameter of the same-frequency measurement is greater than the first threshold value.
[0128] That is to say, to determine whether the measurement interval is effective, it is necessary to consider the information in (1) and (2) at the same time. The index parameter for co-frequency measurement in the embodiment of the present application refers to the index parameter when LP-WUR performs co-frequency measurement. The index parameter can specifically be one or more of RSRP, RSRQ or signal to interference plus noise ratio (SINR) of co-frequency measurement. The method for determining the first threshold value corresponding to RSRP or RSRQ can refer to the above description and is carried by SIB. That is, the first threshold value corresponding to the index parameter for co-frequency measurement in the embodiment of the present application is the same as the threshold value for co-frequency measurement of NR (the method for obtaining the threshold value for co-frequency measurement of NR is the same). In some cases, the first threshold value may also be different from NR, that is, it is not carried by SIB, but is directly indicated by the first indication information sent by the second device, and the first indication information can be carried in at least one of the following messages: downlink control information (DCI), control element (CE) of the control unit of the media access control (MAC), or RRC signaling.
[0129] In other cases, the first threshold value may be determined based on the second threshold value of the same-frequency measurement of the NR and an incremental value. Assuming that the first threshold value is y, the second threshold value is x, and the incremental value is δ, then y=x+δ, and δ may be a positive number or a negative number. Among them, x may be determined based on the parameters carried in the SIB (specifically, for example, the inter-frequency measurement threshold value of the aforementioned NR is based on SIB2) (or based on SSB), and δ may be predefined. Or δ may be indicated in the threshold indication information sent by the second device (such as the RAN device) received by the first device. The first threshold value y can be determined based on x and δ. By using this method to determine the first threshold value, an incremental amount can be added to the second threshold value originally indicated by the NR, thereby reducing the computational cost of determining the first threshold value.
[0130] The threshold indication information can be carried in the SIB like the second threshold value. Or the threshold indication information can be carried in one or more messages in DCI, RRC signaling or MAC-CE. For example, in the RRC connected state, δ can be dynamically indicated by DCI. If the value of δ does not change over a period of time, it can be configured through MAC-CE or RRC. The value of δ is related to the modulation mode of LP-WUS, the architecture of the receiver, the coverage requirements, the power consumption requirements, the measurement accuracy, the synchronization accuracy, and whether the LP-WUS performs coverage enhancement (repetition, precoding), etc., and is not specifically limited in the embodiments of the present application.
[0131] The state of the measurement interval is determined based on the first condition, which may include the following situations:
[0132] Table 1
[0133]
[0134]
[0135] According to Table 1, the states of determining the measurement interval based on the first condition include the following situations:
[0136] (A1) LP-WUS indicates that data will be transmitted, and the indicator parameter of the same-frequency measurement is greater than (or not less than) the first threshold value, and the state of the measurement interval is determined to be in an invalid state.
[0137] LP-WUS indicates that data will be transmitted. It is important to avoid inter-frequency measurements affecting data transmission. If the intra-frequency measurement parameter is greater than (or not less than) the first threshold, the signal quality of the intra-frequency measurement is good, and switching the serving cell is not necessary. At this time, the measurement interval is inactive, and inter-frequency measurements are not performed.
[0138] (A2) The LP-WUS indicates that data will be transmitted, and the indicator parameter of the same-frequency measurement is not greater than (or less than) the first threshold value, and the state of the measurement interval is determined to be the valid state.
[0139] That is, LP-WUS indicates that data transmission is imminent, and the signal quality of the intra-frequency measurement is poor. To prevent the terminal's communication quality from affecting data transmission, a measurement interval can be activated. During this measurement interval, inter-frequency measurements are performed to allow the terminal to switch to a cell with better signal quality, thereby improving communication quality and data transmission.
[0140] (A3) If the low-power wake-up signal indicates no data transmission and the indicator parameter of the same-frequency measurement is not greater than (or less than) the first threshold value, the state of the current measurement interval is used. Among them, the state of the current measurement interval is used. There are two meanings:
[0141] a. If the current measurement interval status is valid, determine that the measurement interval status is valid.
[0142] b. If the current measurement interval status is an inactive state, determine that the measurement interval status is an inactive state.
[0143] In other words, if the signal quality of the terminal device's current intra-frequency measurement is poor, but the LP-WUS indicates no data transmission, whether the terminal device performs inter-frequency measurement to improve communication quality during the measurement interval will not affect data transmission. Therefore, the current measurement interval status can be maintained.
[0144] (A4) If the low-power wake-up signal indicates that there is no data transmission and the indicator parameter of the same-frequency measurement is greater than (or not less than) the first threshold value, the state of the current measurement interval is used.
[0145] In other words, if the terminal device's current intra-frequency measurement signal quality is good, but the LP-WUS indicates no data transmission, whether the terminal device performs inter-frequency measurement within the measurement interval to further improve communication quality will not affect data transmission. Therefore, the current measurement interval status can be maintained.
[0146] It can be seen that in the embodiment of the present application, the LP-WUS indication of whether there is data transmission and whether the index parameter of the same-frequency measurement is greater than the first threshold value are used to judge the status of the measurement interval. While taking into account the signal quality of the same-frequency measurement, it is also considered whether the different-frequency measurement will affect the data transmission, thereby improving the reliability of determining the status of the measurement interval and applying it to the different-frequency measurement, thereby improving the communication quality of the terminal device.
[0147] The state of the above-mentioned measurement interval can be determined by the first device based on the first condition. Specifically, a predefined rule can be generated according to the first condition, such as the above-mentioned Table 1. Table 1 is then stored in the terminal device, and the second device configures the measurement interval to the terminal device in advance. The predefined rule can also be in other forms, such as a process described in text, etc., and the form of expression is not limited here. The terminal device determines the state of the measurement interval through conditional triggering. For example, after the above-mentioned conditions are met, the measurement interval automatically takes effect or does not take effect, or activates or deactivates the pre-configured measurement interval. It is equivalent to an implicit provision.
[0148] In other cases, the second device may determine the status of the measurement interval based on the first condition, and then notify the first device of the status of the measurement interval. Figure 3B A flow chart of another measurement method is provided in Figure 3B As shown, the method includes step 203, the second device sends status indication information to the first device, and correspondingly, the first device receives the status indication information from the second device, where the status indication information is used to indicate the status of the measurement interval.
[0149] The second device may be a RAN device. The RAN device determines the status of the measurement interval based on the first condition, and then indicates the status of the measurement interval to the first device through status indication information. The status indication information may be carried in at least one of the following messages: DCI, MAC-CE, or RRC signaling. The type of signaling depends on the requirements for the effective time. For example, in some scenarios, such as data services with very high latency requirements, DCI can be used to quickly send status indication information to determine the status of the measurement interval. In some service scenarios with general latency requirements, MAC-CE can be used to carry status indication information. If the measurement interval remains effective or ineffective for a long period of time, it may be considered to use RRC signaling to carry the status indication information.
[0150] In the embodiment of the present application, the first device determines the state of the measurement interval according to the first condition, which can ensure the timeliness of determining the state of the measurement interval. The state indication information sent by the second device determines the state of the measurement interval, which can reduce the power consumption of the first device.
[0151] In some possible cases, the first condition also includes indication information about the measurement interval in the network message, including an indication that the measurement interval needs to be configured for measurement, or that measurement detection does not need to be configured for measurement. For details, please refer to Table 2:
[0152] Table 2
[0153]
[0154] According to Table 1, the states of determining the measurement interval based on the first condition include the following situations:
[0155] (B1) LP-WUS indicates that data will be transmitted, the indicator parameter of the same-frequency measurement is greater than (or not less than) the first threshold value, and the network message indicates that the measurement interval does not need to be configured for measurement, and the status of the measurement interval is determined to be invalid.
[0156] The LP-WUS indicates that data transmission is imminent, and the signal quality of the same-frequency measurement is good. It is necessary to avoid the impact of inter-frequency measurements on data transmission. The network message indicates that no measurement interval needs to be configured for measurement, meaning that inter-frequency measurements are not required. At this point, the measurement interval status is determined to be inactive.
[0157] (B2) LP-WUS indicates that data will be transmitted, the indicator parameter of the same-frequency measurement is not greater than (or less than) the first threshold value, and the network message indicates that a measurement interval needs to be configured for measurement, and the status of the measurement interval is determined to be in the effective state.
[0158] LP-WUS indicates that data transmission is imminent, and the signal quality of intra-frequency measurements is poor. It is important to minimize the impact of poor communication quality on the terminal device on data transmission. The network message also indicates that a measurement interval needs to be configured for measurement. At this point, the measurement interval status is set to active, allowing inter-frequency measurements to be performed.
[0159] (B3) If the low-power wake-up signal indicates no data transmission, the indicator parameter of the same-frequency measurement is not greater than (or less than) the first threshold value, and the network message indicates that no measurement interval needs to be configured for measurement, the current measurement interval state is used.
[0160] The signal quality of the terminal device's current intra-frequency measurement is poor, but the LP-WUS indicates no data transmission. Regardless of whether the terminal device performs inter-frequency measurement to improve communication quality within the measurement interval, it will not affect data transmission. In addition, the network device also indicates that there is no need to configure a measurement interval for measurement. Assuming that the current measurement interval status is inactive, it can remain inactive. However, assuming that the current measurement interval status is active, it may be that intra-frequency measurement or other operations require a measurement interval, and it can also remain active.
[0161] (B4) If the low-power wake-up signal indicates no data transmission, the indicator parameter of the same-frequency measurement is greater than (or not less than) the first threshold value, and the network message indicates that no measurement interval needs to be configured for measurement, the current measurement interval state is used.
[0162] The terminal device's current intra-frequency measurement signal quality is good, but the LP-WUS indicates no data transmission. Regardless of whether the terminal device performs inter-frequency measurements during the measurement interval to further improve communication quality, data transmission will not be affected. Furthermore, the network device indicates that no measurement interval is required. Therefore, the current measurement interval status can be maintained.
[0163] It should be noted that, assuming that the first condition includes indication information about the measurement interval in the network message, the process of determining the state of the measurement interval can be determined by the first device based on the first condition. The second device can simply send a network message to the first device.
[0164] During the above implementation process, the process of the first device receiving the indication information is the process of transmitting data or signaling with the second device. Therefore, the first device receives the indication information sent by the second device through the main receiver, including status indication information, threshold indication information, or first indication information, etc.
[0165] It can be seen that in the embodiment of the present application, the status of the measurement interval is judged by combining the LP-WUS indication of whether there is data transmission, whether the index parameter of the same-frequency measurement is greater than the first threshold value, and the network device indication of whether a measurement interval needs to be configured for measurement. While taking into account the signal quality of the same-frequency measurement, whether the different-frequency measurement will affect the data transmission, as well as the demand indication of the network device, the reliability of determining the status of the measurement interval and applying it to the different-frequency measurement is further improved, thereby improving the communication quality of the terminal device.
[0166] The above embodiment describes a method for performing inter-frequency measurement by the primary receiver within a measurement interval when the measurement interval is in effect. The present application also provides a method for performing inter-frequency measurement by the primary receiver within a measurement interval when other conditions are met. Figure 4A , Figure 4A A flowchart of another signal measurement method provided in an embodiment of the present application is applied to a first device, the first device including a main receiver and a low-power wake-up receiver, such as Figure 4A As shown, the method includes the following steps:
[0167] 301. Perform co-frequency measurement by waking up the receiver with low power consumption.
[0168] The process of performing co-frequency measurement through LP-WUR can refer to the relevant description in the aforementioned step 201, which will not be repeated here.
[0169] 302. When the second condition is met and the status of the measurement interval is determined to be in an effective state, heterofrequency measurement is performed through the main receiver within the measurement interval. The second condition includes at least one of the following conditions: the frequency priority of the target cell is not lower than the frequency priority of the serving cell; or the serving cell is the cell with the largest indicator parameter among multiple cells measured at the same frequency.
[0170] In the embodiment of the present application, in combination with the second condition, and when the state of the measurement interval is in the valid state, the inter-frequency measurement is performed by MR within the measurement interval. The second condition includes one or both of the following two conditions:
[0171] (1) The frequency priority of the target cell is not lower than (or higher than) the frequency priority of the serving cell.
[0172] Specifically, the LP-WUR in the terminal device can learn which operating frequencies the terminal device supports. Depending on the needs of the operator, different frequencies may have different priorities for a certain terminal device. Frequencies may include third-generation (3G) mobile communication frequencies, fourth-generation (4G) mobile communication frequencies, 5G frequencies, or 6G frequencies. The priorities of these frequencies can be increased in sequence. That is, 3G frequency ≤ (less than or equal to) 4G frequency ≤ 5G frequency ≤ 6G frequency. Among them, "≤" can also be replaced by "< (less than)".
[0173] For the terminal device, assuming that the frequency of the current serving cell is 5G and the frequency of the target cell is 4G, even if the measurement interval is in the effective state, the terminal device will not perform inter-frequency measurement of the target cell within the measurement interval, nor will it switch to the target cell of the 4G frequency because the signal quality of the 4G frequency is better.
[0174] The method steps in the embodiment of the present application are illustrated by taking inter-frequency measurement as an example. In fact, the terminal device does not perform low-priority (or equal-priority) measurements, but only performs high-priority measurements. The measurements that can be applied include same-frequency neighboring area measurements, or inter-frequency neighboring area measurements, or inter-system measurements, or other measurements, such as inter-system (inter-RAT) measurements of the evolved universal terrestrial radio access (E-UTRA) frequency. These measurements can be specifically performed by LP-WUR or MR in the terminal device, and the embodiment of the present application is not limited thereto.
[0175] (2) The serving cell is the cell with the largest indicator parameter among multiple cells measured on the same frequency.
[0176] When performing intra-frequency measurement, the terminal device first determines whether the terminal device's current serving cell is the cell with the largest indicator parameter among multiple intra-frequency cells. The indicator parameter for intra-frequency measurement can be RSRQ, RSRP, or SNR, as described in the previous embodiments, or can also be other indicator parameters, which are not limited in the embodiments of this application. The larger the indicator parameter, the better the cell signal quality. The cell with the largest indicator parameter is the cell with the best signal quality.
[0177] Determine that the service cell of the terminal device is the cell with the best signal quality, and then combine the conditions for judging whether the measurement interval is effective, including the conditions for setting the same-frequency measurement, such as whether the indicator parameter of the same-frequency measurement is greater than the first preset threshold.
[0178] In an embodiment of the present application, it is first determined that the terminal device meets the second condition, and then it is determined that the terminal device performs heterofrequency measurement in a state where the measurement interval is effective. The second condition includes one of the following two conditions: the frequency priority of the target cell is not lower than the frequency priority of the service cell, or the service cell is the cell with the largest index parameter among multiple cells for same-frequency measurement. For the former condition, it can ensure that the terminal device always operates at a frequency with a higher priority in order to better obtain communication services. For the second condition, it can further ensure the accuracy of the judgment that the terminal device needs to perform heterofrequency measurement to obtain better cell service. Avoid the impact on data transmission that may be caused by frequent and unnecessary heterofrequency measurements, and reduce the power consumption that may be caused by unnecessary wake-up of the main receiver.
[0179] The terminal device determines whether the above Figure 3A-3B The corresponding embodiment or Figure 4A The purpose of performing inter-frequency measurement is to obtain a cell with better signal quality from a target cell with a different frequency point from the current serving cell as a new serving cell, so as to provide better communication services for the terminal device.
[0180] The method of determining a new serving cell through inter-frequency measurement may specifically include the following two methods:
[0181] 1) The first cell is determined as a new serving cell, an index parameter of the first cell is greater than that of the serving cell, and a difference between the index parameter of the first cell and the index parameter of the serving cell is greater than a preset threshold.
[0182] See Figure 4B , Figure 4B A schematic diagram of a scenario of switching a serving cell provided in an embodiment of the present application is shown in FIG. Figure 4B As shown in (a), the cells that the LP-WUR in the terminal device performs inter-frequency measurement on include the current serving cell C0, the first cell C1, the second cell C2, and the third cell C3. The index parameters of C1 and C2 are both greater than the current serving cell C0. However, the index parameter R of C1 is C1 and the index parameter R of C0 C0 The difference is greater than the preset threshold M (for example, M can be 3dB), and the index parameter R of C2 C2 With R C0 The difference is less than (or not greater than) M. Therefore, the first cell is determined as the new serving cell, such as Figure 4B As shown in (b) in .
[0183] Optionally, the second device sends second indication information to the first device, where the second indication information is used to indicate a preset threshold; and the first device receives the second indication information from the second device.
[0184] That is, the preset threshold M is indicated by the second device (RAN device). After receiving the preset threshold indicated by the second device, the first device determines whether there is a new serving cell that satisfies the indicator parameter difference with the serving cell by more than the preset threshold, and switches to the new serving cell. The second indication information can be carried in any one or more messages of SIB, DCI, MAC-CE, or RRC signaling.
[0185] If possible, the preset threshold value may also be predefined in the terminal device, and the terminal device can directly obtain the preset threshold value from itself.
[0186] In some cases, it may also be determined that within the first time period, the difference between the index parameter of the first cell and the index parameter of the serving cell is greater than a preset threshold.
[0187] For example, when it is determined that the difference between the index parameters of the first cell and the service cell is greater than the preset threshold, the timer is turned on to ensure that the difference between the index parameters of the first cell and the service cell is always greater than the first preset threshold within the first time period when the timer is turned on, and the first cell is determined to be a new service cell. That is, the first cell provides communication services for the terminal device. If the difference between the index parameters of the first cell and the service cell is less than (or not greater than) the first preset threshold at a certain moment t1 within the first time period, the timer is reset. And when it is rediscovered that the difference between the index parameters of a certain cell (which can be the first cell or other cells) and the index parameters of the first cell is greater than the preset threshold, the timer is turned on again. Repeatedly determine whether the difference between the index parameters of the cell and the service cell remains greater than the first preset threshold within the first time period. If so, the cell is determined to be a new service cell.
[0188] 2) The second cell is determined as a new serving cell, the index parameter of the second cell is greater than the index parameter of the serving cell, and within the first time period, the index parameter of the second cell is greater than that of other cells measured in different frequencies.
[0189] See Figure 4C , Figure 4C A schematic diagram of a process for determining a second cell provided in an embodiment of the present application is shown as follows: Figure 4C As shown, at time T0, the terminal device works in the serving cell D0 and starts inter-frequency measurement. The cells measured include the current serving cell D0, the first cell D1, the second cell D2, and the third cell D3. At time T1, the indicator parameter R of D2 is determined. D2 Greater than the index parameter R of the current serving cell D0 D0 , and R D2 >(greater than)Choose(R D1 , R D3), where Choose() represents a function that selects one of them. Or it can be expressed as R D2 >Choose(R D0 , R D1 , R D3 ), that is, the largest indicator parameter becomes D2, and timer H2 is started to count D2. If within the first time period of timer H2, R D2 If the value remains at the maximum value, the second cell is determined to be the cell with the best signal quality. The second cell is determined as the new serving cell. After H2 ends, the terminal device switches from the communication connection with the serving cell D0 to the communication connection with D2.
[0190] Similarly, the first duration may be indicated by the second device through third indication information, and the third indication information may be carried in any one or more messages of SIB, DCI, MAC-CE, or RRC signaling. Alternatively, the first duration may be predefined in the first device, and the terminal device may obtain the first duration from itself when needed.
[0191] It should be noted that the above embodiment is described by taking the terminal device performing inter-frequency measurement as an example. If possible, assuming that the same-frequency measurement process corresponds to multiple cells, the new serving cell can also be determined by the above methods 1) and 2). This embodiment of the present application does not limit this.
[0192] It can be seen that in the embodiment of the present application, when it is determined that the difference between the index parameter of the first cell and the index parameter of the serving cell is greater than the preset threshold, or when it is determined that the second cell is the cell with the largest index parameter among multiple cells (including the serving cell) measured at different frequencies within the first time period, it is determined that the first cell or the second cell will be used as the new serving cell. The accuracy of determining the serving cell of the terminal device can be guaranteed. The impact of frequent switching of the serving cell on the data transmission process of the terminal device can be avoided.
[0193] The above two methods of determining a new serving cell (1) and (2) can be combined. One combination method is as described above, where the first duration is also introduced in method (1), and if the first cell always maintains an index parameter greater than a preset threshold value than the serving cell during the first duration, the first cell is determined as the new serving cell. Another combination method is, assuming that both the first cell and the second cell satisfy (within the first duration) that the difference between the index parameter and the serving cell is greater than a preset threshold value, then the cell with the larger index parameter between the first cell and the second cell is selected as the new serving cell.
[0194] The above is an example for determining a new serving cell. In some cases, other methods may also be used to determine a new serving cell, which is not limited in the embodiments of the present application.
[0195] The embodiments of the present application can be combined with the aforementioned Figure 3A-3B In combination with the embodiment described above, that is, in step 302, "when it is determined that the state of the measurement interval is in the effective state, the main receiver performs inter-frequency measurement within the measurement interval", the conditions or process for determining the state of the measurement interval are completely referred to above. Figure 3A-3B Related description.
[0196] Alternatively, in other cases, the embodiment of the present application may also be a separate embodiment. That is, in step 302, the conditions or process for determining the state of the measurement interval are the same as those described above. Figure 3A-3B For example, whether the measurement interval is effective can be determined only by "whether the index parameter of the same-frequency measurement is greater than the first threshold value". The method for determining the first threshold value can be the method in the existing NR or the method in the Figure 3A-3B The method described in the embodiment of the present application is not limited. The conditions for determining the state of the measurement interval can also be other conditions, which are not listed one by one in the embodiment of the present application.
[0197] In other cases, step 302 in the embodiment of the present application can be replaced with 302a, and inter-frequency measurement is performed by the primary receiver when the second condition is met, and the second condition includes: the frequency priority of the target cell is not lower than the frequency priority of the serving cell. In other words, the terminal device does not need to determine that the measurement interval is effective (it can only need to determine that there is no data transmission) to perform inter-frequency measurement. This embodiment of the present application is not limited.
[0198] In combination with the above embodiments, the present application also provides a method for relaxing the same-frequency measurement, which is applied to a first device including LP-WUR and MR. Figure 5 , is a flow chart of a same-frequency measurement method provided in an embodiment of the present application, such as Figure 5 As shown, the method includes the following steps:
[0199] 401. Perform co-frequency measurement by waking up the receiver with low power consumption;
[0200] 402. When the third condition is met, the co-frequency measurement of the low-power wake-up receiver is relaxed, wherein the third condition includes that the index parameter of the co-frequency measurement is greater than the first threshold value, and may also include at least one of the following conditions: the frequency priority of the target cell is not lower than the frequency priority of the serving cell; or the serving cell is the cell with the largest index parameter among multiple cells for co-frequency measurement.
[0201] Measurement relaxation refers to lengthening the measurement period and reducing the measurement frequency. LP-WUR co-frequency measurement relaxation can take two forms: one is to reduce the transmission power of synchronization signals (such as secondary synchronization signals (SSS) or other communication signals), and the other is to increase the transmission period of synchronization signals.
[0202] In an embodiment of the present application, whether to perform LP-WUR co-frequency measurement relaxation can be determined only by whether the index parameter of the co-frequency measurement is greater than the first threshold value. If it is greater than (or not less than) the first threshold value, it indicates that the signal quality of the current co-frequency measurement is good, and the LP-WUR co-frequency measurement relaxation can be performed. If it is not greater than (or less than) the first threshold value, it indicates that the signal quality of the current co-frequency measurement is poor, and the LP-WUR co-frequency measurement relaxation is not performed.
[0203] Alternatively, the embodiment of the present application can combine one or both of the following conditions: the index parameter of the same-frequency measurement is greater than the first threshold value, and the frequency priority of the target cell is not lower than the frequency priority of the serving cell; or the serving cell is the cell with the largest index parameter among multiple cells for the same-frequency measurement, to jointly determine whether LP-WUR performs same-frequency measurement relaxation (measurement relaxation of the same-frequency measurement).
[0204] The frequency priority of the target cell (which can be the target cell for intra-frequency measurement or inter-frequency measurement) is not lower than (or higher than) the frequency priority of the serving cell. This may be because the operator wants the terminal device to operate at a higher-priority frequency. Therefore, the conditions for cell handover are met only when the frequency priority of the target cell is not lower than that of the serving cell. This indicates that the terminal device has found a cell with better signal quality for handover. At this time, intra-frequency measurement relaxation can be performed, reducing the frequency of intra-frequency measurements and improving energy savings.
[0205] The serving cell is the cell with the largest indicator parameter among multiple cells measured at the same frequency. For specific judgment methods, please refer to the above Figures 4A to 4C The cell with the largest indicator parameter among multiple cells that meet the requirement of serving cell for co-frequency measurement indicates that the current serving cell is the cell with the best signal quality that can provide services to the terminal device. The terminal device does not need to switch serving cells in a short period of time. In this case, co-frequency measurement relaxation can be performed to reduce the frequency of co-frequency measurement and improve energy saving gain.
[0206] In the above embodiment, for the first device supporting the LP-WUS feature, the LP-WUR performs intra-frequency measurement and the MR performs inter-frequency measurement. If possible, the LP-WUR may perform inter-frequency measurement, or the MR may perform intra-frequency measurement.
[0207] See also Figure 6 , Figure 6 A flow chart of another measurement method provided in an embodiment of the present application, the method comprising the following steps:
[0208] 501. Perform co-frequency measurement by waking up the receiver with low power consumption;
[0209] 502. During the measurement interval, inter-frequency measurement is performed through a low-power wake-up receiver or a main receiver, wherein, when the inter-frequency measurement is performed through the low-power wake-up receiver, the measurement rule of the inter-frequency measurement is one of the following: determining the measurement quality based on the secondary synchronization signal SSS; or determining the measurement quality based on the SSS and the demodulation reference signal DMRS of the physical broadcast channel PBCH.
[0210] The process of performing the same-frequency measurement by LP-WUR in step 501 can refer to the relevant description in the aforementioned step 201, which will not be repeated here.
[0211] Step 502 can use existing technology to determine whether the measurement interval is effective, or it can be combined with the method for determining the effective state of the measurement interval described in step 202 to determine whether the measurement interval is effective. Figures 4A to 4C The embodiment of the invention determines whether to perform inter-frequency measurement, and / or combines Figure 5 The embodiment in the embodiment determines whether to perform same-frequency measurement relaxation, etc., and the embodiment of this application does not make specific limitations.
[0212] In the embodiment of the present application, inter-frequency measurements can be performed using either the LP-WUR or the MR during the measurement interval. Using the LP-WUR for inter-frequency measurements avoids waking up the MR when no data is being transmitted, reducing power consumption in the terminal device. Using the MR for inter-frequency measurements improves the effectiveness and efficiency of inter-frequency measurements due to its greater processing power.
[0213] When performing inter-frequency measurement by waking up the receiver with low power consumption, the measurement rule of the inter-frequency measurement is one of the following:
[0214] (1) Determine the measurement quality based on the secondary synchronization signal SSS.
[0215] The SSS is part of the third symbol of the SSB in NR and occupies 127 subcarriers. Using the SSS can be used to fully distinguish different cell types and reduce the amount of data processed compared to using SSB for inter-frequency measurements in existing NR. Measurement quality based on the SSS can be determined, as described above, by whether the RSRP or RSRQ of the SSS is greater than a threshold.
[0216] (2) Determine the measurement quality based on the SSS and the demodulation reference signal DMRS of the physical broadcast channel PBCH.
[0217] Jointly determining measurement quality based on the SSS and PBCH DMRS enriches the parameters used to determine signal quality, improving measurement accuracy. This, in turn, requires higher processing performance.
[0218] For a first device supporting the LP-WUS feature, the RAN device may indicate which measurement rule to use. That is, the method further includes, before step 502, step 503 (not shown in the figure), in which the second device sends second indication information to the first device, where the second indication information is used to indicate the measurement rule for performing inter-frequency measurement. Correspondingly, the first device receives the second indication information and determines the measurement rule for performing inter-frequency measurement based on the second indication information. The second indication information may be carried in an SIB. Alternatively, the second indication information may be carried in at least one of DCI, RRC signaling, or MAC-CE messages.
[0219] For example, in the RRC idle state, SIB1 carries the second indication information. Specifically, for example, bit state 0 indicates that the measurement quality is determined based on the SSS, and bit state 1 indicates that the measurement quality is determined based on the SSS and PBCH DMRS. Alternatively, SIB1 adds a configuration parameter SupportCombinMeas. The presence of this parameter indicates that the measurement quality is determined based on a joint solution. The absence of this parameter indicates that the measurement quality is determined based on the SSS by default. In addition to SIB1 carrying relevant information, other SIBs can also be used to carry indication information, such as SIB2 or SIB3.
[0220] It should be noted that before the second device sends the second indication information to instruct the LP-WUR in the first device to perform inter-frequency measurement measurement rules, the second device may also receive a capability report from the first device, and determine whether the first device supports the LP-WUS feature based on the capability report, and further determine whether the LP-WUR of the first device supports inter-frequency measurement. This avoids the second device sending the measurement rule to the first device that does not support LP-WUR for inter-frequency measurement, resulting in invalid signal transmission overhead.
[0221] It can be seen that in the embodiment of the present application, the low-power wake-up receiver can perform inter-frequency measurements and determine the measurement quality through SSS, or SSS and PBCH DMRS. In this way, using a low-power wake-up receiver for inter-frequency measurements can reduce the wake-up frequency of the main receiver and reduce the energy consumption of the terminal device. The measurement rules configured for the low-power wake-up receiver can meet the low processing performance requirements of the low-power wake-up receiver, or meet the requirements of higher measurement accuracy, thereby improving the reliability of the inter-frequency measurement of the low-power wake-up receiver.
[0222] Optionally, the method further includes: if the inter-frequency measurement is performed through the main receiver, switching from performing the same-frequency measurement through the low-power wake-up receiver to performing the same-frequency measurement through the main receiver.
[0223] In this embodiment of the present application, inter-frequency measurements can also be performed using MR. If MR has already been awakened for inter-frequency measurements, it can also be used for intra-frequency measurements. This means that the terminal device switches from performing intra-frequency measurements using LP-WUR to performing intra-frequency measurements using MR. This improves the measurement accuracy of intra-frequency measurements without increasing energy consumption.
[0224] The above-mentioned rules (1) and (2) for different frequency measurements can also be applied to same-frequency measurements, including same-frequency measurements performed by LP-WUR or same-frequency measurements performed by MR. This embodiment of the present application does not limit this.
[0225] Furthermore, when an MR performs intra-frequency measurements, the corresponding intra-frequency measurement rule can be to determine measurement quality based on the SSS. Specifically, the signal quality of the intra-frequency measured cell is determined by whether the SSS indicator parameter is greater than a threshold. This is because the MR has stronger processing capabilities and can ensure good measurement accuracy and reduce measurement errors even when using only the SSS.
[0226] While the MR performs inter-frequency measurements, the LP-WUR can also perform intra-frequency measurements, and the LP-WUR can also relax intra-frequency measurements. This ensures that the terminal device can access a cell with a better signal through the MR's inter-frequency measurements, while also reducing the terminal device's energy consumption by relaxing intra-frequency measurements for the LP-WUR.
[0227] In some cases, different measurement relaxation settings can be made depending on whether the LP-WUS carries the wake-up information of a terminal device or a group of terminal devices.
[0228] 1) When the low-power wake-up signal carries the wake-up information of the terminal group's identifier, the primary receiver performs measurement relaxation of the inter-frequency measurement.
[0229] When LP-WUS carries wake-up information identifying a terminal group, the false alarm rate (false alarm rate) for individual terminal devices can be relatively high. This rate is the probability that a terminal device, upon receiving an LP-WUS, will mistakenly interpret a signal that is not intended to wake up the mobile station as one intended to do so. To reduce this false alarm rate, the inter-frequency measurement period for the mobile station can be relaxed, increasing the inter-frequency measurement period. This allows the mobile station to remain in a dormant state for a longer period of time, thus reducing the energy consumption associated with this false alarm rate.
[0230] In this case, assuming that LP-WUR performs heterofrequency measurement, measurement relaxation of heterofrequency measurement is also required. The period of heterofrequency measurement of LP-WUR is lengthened, and LP-WUR can be in a deep sleep state or an ultra-deep sleep state for a long time.
[0231] 2) When the low-power wake-up signal carries the wake-up information of the terminal group's identifier, the low-power wake-up receiver performs measurement relaxation for the same-frequency measurement.
[0232] When the LP-WUS carries the wake-up information of a single terminal, the false alarm rate for that terminal is relatively low. To maintain a low false alarm rate, the LP-WUR requires a smaller measurement period when performing intra-frequency measurements to ensure greater measurement accuracy. Correspondingly, when the LP-WUS carries the wake-up information of a terminal group, the LP-WUR can use a longer measurement period for intra-frequency measurements, which means that the intra-frequency measurements are relaxed.
[0233] It can be seen that in the embodiment of the present application, the LP-WUS carries the wake-up information of a terminal device or a terminal device group, and performs different measurement relaxations of different frequency measurements or same-frequency measurements, which can make a more accurate choice between ensuring measurement accuracy and reducing device energy consumption according to different situations.
[0234] like Figure 7 The structural diagram of the communication device shown in the figure, the embodiment of the present application also provides a communication device 1100, which can be a terminal device, or can be used for but not limited to a terminal device. The communication device 1100 includes a low-power wake-up receiving module 1101, a main receiving module 1102 and a processing module 1103. The low-power wake-up receiving module 1101 and the main receiving module 1102 can be or can be deployed in a unit or module that can realize the information receiving and sending function, such as a transceiver, a transceiver antenna, an input and output interface. The processing module 1103 can be or can be deployed in a processor. Among them,
[0235] A low-power wake-up receiving module 1101 is used to perform same-frequency measurement;

[0238] Optionally, the state of the measurement interval is determined based on the first condition, including: if the low-power wake-up signal indicates that data will be transmitted, the index parameter of the same-frequency measurement is greater than or not less than the first threshold value, and the state of the measurement interval is determined to be an ineffective state; or if the low-power wake-up signal indicates that data will be transmitted, the index parameter of the same-frequency measurement is not greater than or less than the first threshold value, and the state of the measurement interval is determined to be an effective state; or if the low-power wake-up signal indicates that there is no data transmission, the index parameter of the same-frequency measurement is not greater than or less than the first threshold value, and the state of the current measurement interval is an effective state, and the state of the measurement interval is determined to be an effective state; or if the low-power wake-up signal indicates that there is no data transmission, the index parameter of the same-frequency measurement is not greater than or less than the first threshold value, and the state of the current measurement interval is an effective state, If the low-power wake-up signal indicates that there is no data transmission, the index parameter of the same-frequency measurement is not greater than or less than the first threshold value, and the status of the current measurement interval is in an invalid state, the status of the measurement interval is determined to be an invalid state; or if the low-power wake-up signal indicates that there is no data transmission, the index parameter of the same-frequency measurement is greater than or not less than the first threshold value, and the status of the current measurement interval is in an effective state, the status of the measurement interval is determined to be an effective state; or if the low-power wake-up signal indicates that there is no data transmission, the index parameter of the same-frequency measurement is greater than or not less than the first threshold value, and the status of the current measurement interval is in an invalid state, the status of the measurement interval is determined to be an invalid state.
[0239] Optionally, the first condition further includes indication information about the measurement interval in the network message.

[0241] Optionally, the first threshold value is determined based on the second threshold value and the increased value, the second threshold value is determined by the synchronization signal block SSB, and the increased value is predefined; or the main receiving module 1102 is also used to receive threshold indication information from the second device, the threshold indication information is used to indicate the increased value, and the threshold indication information is carried in at least one message in the system message block SIB, DCI, RRC signaling or MAC-CE.
[0242] Optionally, the main receiving module 1102 is further used to receive first indication information from the second device, where the first indication information is used to indicate a first threshold value, and the first indication information is carried in at least one of the following messages: DCI, MAC-CE, or RRC signaling.
