Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a communication method and apparatus. Background Art

[0002] In a narrow band internet of things (NB-IoT) system, there is a concept of a multi-carrier cell, that is, multiple carriers can be configured for a cell. However, among these carriers, only one carrier will carry narrowband-primary synchronization signal (NB-PSS or NPSS), narrowband-secondary synchronization signal (NB-SSS or NSSS), narrowband-physical broadcast channel (NB-PBCH or NPBCH), system information block (SIB), etc. This carrier is called an anchor-carrier, and the other carriers except the anchor-carrier are called non-anchor-carriers.

[0003] A terminal device can measure the quality of a serving cell by measuring NSSS or narrowband reference signal (NRS) on the anchor-carrier, and the measured value obtained can represent the quality of the serving cell. With the evolution and enhancement of the NB-IoT system, non-anchor-carriers can also carry NRS, so the terminal device can also perform measurements on non-anchor-carriers. However, before the terminal device can apply the obtained measured value, it is necessary to convert the measured value of the non-anchor-carrier into the measured value of the anchor-carrier according to the corresponding conversion method. The current conversion method is that a new measured value can be obtained according to the measured value of the non-anchor-carrier and a power difference, and this measured value is the converted measured value.

[0004] After obtaining the converted measured value, the terminal device can determine the difference between the converted measured value and the measured value of the anchor-carrier. If the difference is large, the terminal device considers the measured value of the non-anchor-carrier to be unavailable. However, the channel conditions may not always be the same and there will be some fluctuations, resulting in the possibility that the difference obtained in a certain measurement may be in error. Considering the measured value of the non-anchor-carrier to be unavailable based on the comparison result of a single measurement will lead to a low accuracy in judging whether the measured value of the non-anchor-carrier is available. Summary of the Invention

[0005] The embodiments of the present application provide a communication method and apparatus, which are used to improve the judgment accuracy of whether the measurement value of a non-anchor carrier is available, thereby improving communication efficiency.

[0006] In a first aspect, a first communication method is provided. The method includes: measuring on a non-anchor carrier of a serving cell to obtain a first measurement value; obtaining a first conversion value according to the first measurement value and a first difference, where the first difference is used to indicate the power difference between the non-anchor carrier and the anchor carrier of the serving cell; determining that the difference between the first conversion value and a second measurement value is greater than a first threshold, where the second measurement value is the measurement value obtained by measuring on the anchor carrier, and the measurement processes corresponding to the first measurement value and the second measurement value are two adjacent measurement processes; measuring on the anchor carrier to obtain a third measurement value; and determining whether the first measurement value is available according to the third measurement value.

[0007] This method can be executed by a first communication device. The first communication device can be a communication device or a communication device capable of supporting the functions required for the communication device to implement this method, such as a chip. Exemplarily, the first communication device is a terminal device, or a chip provided in the terminal device for implementing the functions of the terminal device, or other components for implementing the functions of the terminal device. In the following introduction process, it is taken as an example that the first communication device is a terminal device.

[0008] In the embodiments of the present application, the first measurement value obtained on the non-anchor carrier can be compared with the second measurement value obtained on the anchor carrier. If the difference is large (i.e., greater than the first threshold), then measurement can be performed on the anchor carrier again to obtain a third measurement value, and then the first measurement value is compared with the third measurement value to determine whether the first measurement value is available. It is equivalent to not simply using the measurement result of the anchor carrier once to judge whether the result of the non-anchor carrier is available, but using the multiple measurement results of the anchor carrier to judge whether the measurement result of the non-anchor carrier is available, so as to consider the change of the channel condition as much as possible, reduce the error caused by one comparison, and improve the accuracy of the judgment result.

[0009] In an optional implementation manner, determining whether the first measurement value is available according to the third measurement value includes:

[0010] If the difference between the first conversion value and the third measurement value is greater than the first threshold, it is determined that the first conversion value is unavailable; otherwise, it is determined that the first measurement value is available.

[0011] A way to determine whether the first measurement value is available according to the third measurement value is given. The first threshold is configured by a network device, for example, pre-configured in the terminal device, or can be specified by a protocol, etc.

[0012] In an alternative embodiment, measurements are performed once every M DRX cycles, and in every M×N DRX cycles, at least one measurement is performed on the anchor carrier, where N is an integer greater than or equal to 0, and M is an integer greater than or equal to 1.

[0013] In the embodiments of the present application, the terminal device can regularly perform measurements on the anchor carrier, so as to determine whether the measurement results of the non-anchor carrier are available based on the measurement results of the anchor carrier in the recent period as much as possible, avoid too long an interval between the acquisition time of the measurement results of the non-anchor carrier and the acquisition time of the measurement results of the anchor carrier, and improve the accuracy of the determination results.

[0014] In an alternative embodiment, the method further includes:

[0015] Determine that the measurement values obtained from continuously performing measurements on the non-anchor carrier K times are all unavailable, where K is an integer greater than or equal to 1;

[0016] Perform measurements only on the anchor carrier within the first time period.

[0017] If the measurement values obtained from continuously performing measurements on the non-anchor carrier K times are all unavailable, it indicates that the measurement results of the non-anchor carrier have a large deviation from the measurement results of the anchor carrier within a period of time. In this case, the terminal device can continuously perform measurements only on the anchor carrier for a period of time, so as to reduce the error caused by continuing to perform measurements on the non-anchor carrier.

[0018] In an alternative embodiment, the availability of the first measurement value includes one or more of the following cases:

[0019] The first conversion value can be used for filtering;

[0020] The first conversion value can be used to enable neighbor cell measurements;

[0021] The first conversion value can be used to determine whether to relax the measurement conditions.

[0022] In the embodiments of the present application, the measurement value is available, which may include one or more of the following situations: the converted value corresponding to the measurement value can be used for filtering, the converted value corresponding to the measurement value can be used to enable neighbor cell measurement, and the converted value corresponding to the measurement value can be used to determine the relaxation of measurement conditions. For example, when the first measurement value is available, it may include one or more of the following situations: the first converted value can be used for filtering, the first converted value can be used to enable neighbor cell measurement, and the first converted value can be used to determine the relaxation of measurement conditions. For example, when the first measurement value is available, it may include that the first converted value can be used for filtering; or, when the first measurement value is available, it may include that the first converted value can be used to enable neighbor cell measurement; or, when the first measurement value is available, it may include that the first converted value can be used to determine the relaxation of measurement conditions; or, when the first measurement value is available, it may include that the first converted value can be used for filtering and the first converted value can be used to enable neighbor cell measurement; or, when the first measurement value is available, it may include that the first converted value can be used for filtering and the first converted value can be used to determine the relaxation of measurement conditions; or, when the first measurement value is available, it may include that the first converted value can be used to enable neighbor cell measurement and the first converted value can be used to determine the relaxation of measurement conditions; or, when the first measurement value is available, it may include that the first converted value can be used for filtering, the first converted value can be used to enable neighbor cell measurement, and the first converted value can be used to determine the relaxation of measurement conditions. Of course, the availability of the measurement value may also include other situations, or it may not include the above three situations, but include other situations, which are not limited in the embodiments of the present application.

[0023] In an alternative embodiment, the first difference comes from the network device.

[0024] The first difference may indicate the power difference between the non-anchor carrier and the anchor carrier, or rather, the first difference is the power difference between the non-anchor carrier and the anchor carrier. This power difference may come from the network device. For example, the network device sends the first difference to the terminal device, and the terminal device receives the first difference from the network device. This power difference may be obtained by the network device based on the transmission power of the signal sent to the anchor carrier and the transmission power of the signal sent to the non-anchor carrier. That is, the transmission power of the signal sent by the network device to the anchor carrier and the transmission power of the signal sent by the network device to the non-anchor carrier are both known to the network device, and the difference between these two transmission powers can be used as the first difference.

[0025] In a second aspect, a second communication method is provided. The method includes: performing at least one measurement on the anchor carrier of the serving cell in every M×N DRX cycles, where one measurement is performed every M DRX cycles, N is an integer greater than or equal to 0, and M is an integer greater than or equal to 1.

[0026] This method can be executed by a second communication device, which can be a communication device or a communication device capable of supporting the functions required for the communication device to implement this method, such as a chip. Exemplarily, the second communication device is a terminal device, or a chip disposed in the terminal device for implementing the functions of the terminal device, or other components for implementing the functions of the terminal device. In the following introduction, it is assumed that the second communication device is a terminal device as an example.

[0027] In the embodiments of the present application, the terminal device can perform measurements on the anchor carrier regularly, so as to determine whether the measurement result of the non-anchor carrier is available according to the measurement results on the anchor carrier recently as much as possible, avoid the interval between the acquisition time of the measurement result of the non-anchor carrier and the acquisition time of the measurement result of the anchor carrier from being too long, and improve the accuracy of the determination result.

[0028] In an alternative embodiment, the method further includes:

[0029] Performing measurements on the non-anchor carrier of the serving cell to obtain a first measurement value;

[0030] Obtaining a first conversion value according to the first measurement value and a first difference, where the first difference is used to indicate the power difference between the non-anchor carrier and the anchor carrier of the serving cell;

[0031] Determining that the difference between the first conversion value and a second measurement value is greater than a first threshold, where the second measurement value is the measurement value obtained by performing measurements on the anchor carrier, and the measurement processes corresponding to the first measurement value and the second measurement value are two adjacent measurement processes;

[0032] Performing measurements on the anchor carrier to obtain a third measurement value;

[0033] Determining whether the first measurement value is available according to the third measurement value.

[0034] In the embodiments of the present application, the first measurement value obtained on the non-anchor carrier can be compared with the second measurement value obtained on the anchor carrier. If the difference is large (i.e., greater than the first threshold), then measurements can be performed on the anchor carrier again to obtain a third measurement value, and then the first measurement value is compared with the third measurement value to determine whether the first measurement value is available. It is equivalent to not simply using the measurement result of the anchor carrier once to determine whether the result of the non-anchor carrier is available, but using the measurement results of the anchor carrier multiple times to determine whether the measurement result of the non-anchor carrier is available, so as to consider the change of the channel condition as much as possible, reduce the error caused by one comparison, and improve the accuracy of the judgment result.

[0035] In an alternative embodiment, determining whether the first measurement value is available according to the third measurement value includes:

[0036] If the difference between the first conversion value and the third measurement value is greater than the first threshold, it is determined that the first conversion value is unavailable; otherwise, it is determined that the first measurement value is available.

[0037] In an alternative embodiment, the method further includes:

[0038] Determining that the measurement values obtained from measuring on the non-anchor carrier continuously for K times are all unavailable, where K is an integer greater than or equal to 1;

[0039] Measuring only on the anchor carrier within a first time period.

[0040] If the measurement values obtained from measuring on the non-anchor carrier continuously for K times are all unavailable, it indicates that the measurement results of the non-anchor carrier have a large deviation from the measurement results of the anchor carrier within a period of time. In this case, the terminal device can measure only on the anchor carrier for a period of time, so as to reduce the error caused by continuing to measure on the non-anchor carrier.

[0041] In an alternative embodiment, the availability of the first measurement value includes one or more of the following situations:

[0042] The first conversion value can be used for filtering;

[0043] The first conversion value can be used to initiate neighbor cell measurement;

[0044] The first conversion value can be used to determine relaxed measurement conditions.

[0045] In an alternative embodiment, the first difference comes from the network device.

[0046] Regarding the technical effects brought by the second aspect or various possible embodiments, reference can be made to the introduction of the technical effects of the first aspect or the corresponding embodiments.

[0047] In a third aspect, a third communication method is provided. The method includes: determining that the measurement values obtained from measuring on the non-anchor carrier of the serving cell continuously for K times are all unavailable, where K is an integer greater than or equal to 1; measuring only on the anchor carrier of the serving cell within a first time period.

[0048] This method can be executed by a third communication device. The third communication device can be a communication device or a communication device capable of supporting the functions required for the communication device to implement this method, such as a chip. Exemplarily, the third communication device is a terminal device, or a chip provided in the terminal device for implementing the functions of the terminal device, or other components for implementing the functions of the terminal device. In the following introduction, it is taken that the third communication device is a terminal device as an example.

[0049] In an embodiment of the present application, if the measurement values obtained from measurements on the non-anchor carrier for K consecutive times are all unavailable, it indicates that the measurement results of the non-anchor carrier have a large deviation from those of the anchor carrier within a period of time. In this case, the terminal device can measure only on the anchor carrier for a period of time, thereby reducing the error caused by continuing to measure on the non-anchor carrier.

[0050] In an alternative embodiment, the method further includes:

[0051] Measure on the non-anchor carrier of the serving cell to obtain a first measurement value;

[0052] Obtain a first conversion value according to the first measurement value and a first difference, where the first difference is used to indicate the power difference between the non-anchor carrier and the anchor carrier of the serving cell;

[0053] Determine that the difference between the first conversion value and a second measurement value is greater than a first threshold, where the second measurement value is the measurement value obtained from measurement on the anchor carrier, and the measurement processes corresponding to the first measurement value and the second measurement value are two adjacent measurement processes;

[0054] Measure on the anchor carrier to obtain a third measurement value;

[0055] Determine whether the first measurement value is available according to the third measurement value.

[0056] In an embodiment of the present application, the first measurement value obtained on the non-anchor carrier can be compared with the second measurement value obtained on the anchor carrier. If the difference is large (i.e., greater than the first threshold), then measurement can be performed on the anchor carrier again to obtain a third measurement value, and then the first measurement value is compared with the third measurement value to determine whether the first measurement value is available. Instead of simply using the measurement result of the anchor carrier once to determine whether the result of the non-anchor carrier is available, multiple measurement results of the anchor carrier can be used to determine whether the measurement result of the non-anchor carrier is available, so as to consider the change of the channel condition as much as possible, reduce the error caused by one comparison, and improve the accuracy of the judgment result.

[0057] In an alternative embodiment, determining whether the first measurement value is available according to the third measurement value includes:

[0058] If the difference between the first conversion value and the third measurement value is greater than the first threshold, determine that the first conversion value is unavailable; otherwise, determine that the first measurement value is available.

[0059] In an alternative embodiment, measurements are performed every M DRX cycles, and in every M×N DRX cycles, at least one measurement is performed on the anchor carrier, where N is an integer greater than or equal to 0, and M is an integer greater than or equal to 1.

[0060] In the embodiments of the present application, the terminal device can regularly perform measurements on the anchor carrier, so as to determine whether the measurement result of the non-anchor carrier is available based on the measurement result of the anchor carrier in the near future as much as possible, avoid too long an interval between the acquisition time of the measurement result of the non-anchor carrier and the acquisition time of the measurement result of the anchor carrier, and improve the accuracy of the determination result.

[0061] In an alternative embodiment, the availability of the first measurement value includes one or more of the following situations:

[0062] The first conversion value can be used for filtering;

[0063] The first conversion value can be used to enable neighbor cell measurement;

[0064] The first conversion value can be used to determine whether to relax the measurement condition.

[0065] In an alternative embodiment, the first difference comes from the network device.

[0066] Regarding the technical effects brought by the third aspect or various possible embodiments, reference can be made to the introduction of the technical effects of the first aspect or the corresponding embodiments.

[0067] In a fourth aspect, a fourth communication method is provided, which includes: receiving indication information from a network device; determining whether the measurement result of the terminal device on the non-anchor carrier is available according to the indication information.

[0068] This method can be executed by a fourth communication device. The fourth communication device can be a communication device or a communication device capable of supporting the functions required for the communication device to implement this method, such as a chip. Exemplarily, the fourth communication device is a terminal device, or a chip provided in the terminal device for implementing the functions of the terminal device, or other components for implementing the functions of the terminal device. In the following introduction, it is taken as an example that the fourth communication device is a terminal device.

[0069] In an embodiment of the present application, by indicating whether the measurement result of a non-anchor carrier is available through a network device, problems such as errors and additional power consumption caused by the imperfect judgment mechanism of a terminal device for the measurement result of the non-anchor carrier can be reduced. For example, if the network device indicates that the measurement result of the non-anchor carrier is unavailable, the terminal device may not measure on the non-anchor carrier, which can avoid the errors caused by the measurement result of the non-anchor carrier to a certain extent; and if the network device indicates that the measurement result of the non-anchor carrier is available, if the terminal device obtains the measurement result of the non-anchor carrier, it does not need to determine whether the measurement result of the non-anchor carrier is available anymore, but can directly utilize it, reducing the burden on the terminal device.

[0070] In an alternative embodiment, when the measurement result of the non-anchor carrier is unavailable, the method further includes:

[0071] Measuring only on the anchor carrier.

[0072] If the indication information indicates that the measurement result of the non-anchor carrier of the serving cell is unavailable, then the terminal device may measure only on the anchor carrier. For example, the terminal device may always measure only on the anchor carrier. Even if the non-anchor carrier measurement condition is met, the terminal device still measures only on the anchor carrier. Or, the terminal device may measure on the anchor carrier within a second time period. During the second time period, even if the non-anchor carrier measurement condition is met, the terminal device still measures only on the anchor carrier. After the second time period, the terminal device may continue to measure on the anchor carrier, or if the non-anchor carrier measurement condition is met, the terminal device may also measure on the non-anchor carrier. The second time period may be configured by the network device. For example, in addition to the indication information, the first message may further include information about the second time period, or the network device may also indicate the second time period to the terminal device through other messages other than the first message; or, the second time period may be pre-configured in the terminal device; or, the second time period may also be specified by the protocol.

[0073] In an alternative embodiment, the indication information is carried in a system message for configuring the non-anchor carrier.

[0074] For example, the indication information may be carried in a first message and sent to the terminal device. The first message is, for example, a high-layer signaling, and the high-layer signaling is, for example, an RRC signaling or a MAC CE, etc.; or, the first message may also be a physical layer signaling, and the physical layer signaling is, for example, a DCI, etc.; or, the first message may also be a system message, and the system message is, for example, an SIB, for example, the SIB is an SIB for configuring the non-anchor carrier for the terminal device, for example, SIB22. Sending the indication information together with the system message for configuring the non-anchor carrier enables the indication information not to be sent through other messages, which helps to save signaling overhead.

[0075] In a fifth aspect, a fifth communication method is provided, which includes: determining indication information for indicating whether the measurement result of a non-anchor carrier of a serving cell of a terminal device is available; and sending the indication information to the terminal device.

[0076] This method may be executed by a fifth communication device. The fifth communication device may be a communication device or a communication device capable of supporting the functions required for a communication device to implement this method, such as a chip. Exemplarily, the fifth communication device is a network device, or a chip provided in the network device for implementing the functions of the network device, or other components for implementing the functions of the network device. In the following introduction, it is taken as an example that the fifth communication device is a network device.

[0077] In an optional implementation manner, the indication information is carried in a system message for configuring the non-anchor carrier.

[0078] Regarding the technical effects brought by the fifth aspect or various possible implementation manners, reference may be made to the introduction of the technical effects of the fourth aspect or the corresponding implementation manners.

For Internet of Things terminal devices such as smart water / electricity meters, smart homes, cars, wearable devices, etc. with large-scale deployment, there may be a large number of such terminal devices under an NB-IoT base station, for example, there may be tens of thousands.

[0213] (3) Requirement for low cost. Compared with the existing cellular network terminal devices, NB-IoT requires lower cost for terminal devices to achieve massive deployment of terminal devices. And the requirement for low cost requires very low implementation complexity of terminal devices.

[0214] (4) Requirement for low power consumption. NB-IoT requires lower power consumption for terminal devices, thus saving the battery power of terminal devices, ensuring extremely long standby time of terminal devices, and further saving the labor cost of replacing batteries.

[0215] (5) Lower service arrival rate. Usually, there is a service only once in several hours or even more than a day, and a considerable part is triggered by the uplink, that is, the network device will not paging the terminal device. Only when the terminal device has an uplink service, the network device will send downlink response data to the terminal device after receiving the uplink service.

[0216] 4) Discontinuous reception (DRX). Simply put, under the DRX mechanism, the terminal device can enter the sleep state periodically and does not need to monitor the physical downlink control channel (PDCCH).

[0217] 5) The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "At least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, c can be single or multiple.

[0218] Furthermore, unless otherwise specified, ordinal numbers such as "first" and "second" mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the size, content, order, timing, priority or importance of multiple objects. For example, the first measurement value and the second measurement value are only used to distinguish different measurement values, and do not indicate the difference in size, content, acquisition order, priority or importance of the two measurement values.

[0219] The foregoing introduces some terminology concepts involved in the embodiments of the present application. The following introduces the technical features involved in the embodiments of the present application.

[0220] The NB-IoT system has the concept of multi-carrier cells, that is, multiple carriers can be configured for a cell. However, among these carriers, only one carrier will carry NPSS, NSSS, NB-PBCH, SIB, etc. This carrier is called the anchor carrier, and other carriers except the anchor carrier are called non-anchor carriers.

[0221] In the NB-IoT system, if the terminal device wants to measure the quality of the serving cell, it can measure NSSS or NRS on the anchor carrier, and the obtained measurement value (or measurement result) can represent the quality of the serving cell. The measurement value is, for example, narrowband reference signal received power (NRSRP) or narrowband reference signal received quality (NRSRQ).

[0222] With the evolution and enhancement of the NB-IoT system, non-anchor carriers can also carry NRS, so terminal devices can also perform measurements on non-anchor carriers. For terminal devices to perform measurements on non-anchor carriers, the following three conditions must be met:

[0223] 1. Satisfy the relaxed measurement conditions;

[0224] 2. The power difference between the power of the NRS of the non-anchor carrier and the power of the NRS of the anchor carrier is known to the terminal device;

[0225] 3. The terminal device is not configured for positioning measurement.

[0226] The relaxed measurement condition may also be referred to as a relaxed monitoring condition for neighboring cells, which refers to relaxing the measurement of neighboring cells of the serving cell. If the relaxed measurement condition is met, the terminal device may choose not to perform intra-frequency measurement or inter-frequency measurement, or in other words, the terminal device may not perform measurement of neighboring cells.

[0227] Positioning measurement means that the network equipment can configure the terminal equipment to perform measurements related to positioning. For example, a neighboring cell of the service cell of the terminal equipment is used as a reference cell, and the terminal equipment measures the positioning reference signal (PRS) from the reference cell, and measures the PRS from the first neighboring cell, and can determine the time difference between the time when the PRS of the first neighboring cell arrives at the terminal equipment and the time when the PRS of the reference cell arrives at the terminal equipment. The time difference is the reference signal timing difference (RSTD) corresponding to the first neighboring cell. The first neighboring cell is any other neighboring cell of the service cell of the terminal equipment except the reference cell. For example, the terminal equipment can determine the RSTD corresponding to each of the one or more neighboring cells of the service cell of the terminal equipment through measurement. The terminal equipment can report the determined RSTD to the base station, so that the base station can locate the terminal equipment according to the RSTD.

[0228] The above three conditions can also be referred to as non-anchor carrier measurement conditions. If the terminal device determines that the above three conditions are met, the terminal device can measure the NRS on the non-anchor carrier to obtain a measurement value, such as NRSRP or NRSRQ. The terminal device can convert the measurement value into the measurement value of the anchor carrier through the power difference in the above condition 2.

[0229] At present, the terminal device needs to perform a measurement once in each DRX cycle. In a DRX cycle, the anchor carrier can be measured, and the non-anchor carrier can also be measured. The terminal device obtains multiple measurement values ​​by measurement, and at least two measurement values ​​obtained can be filtered. The filtering result can be used for the terminal device to perform corresponding operations. For example, the terminal device can determine to start the neighboring area measurement according to the filtering result, or determine whether the relaxation measurement condition is met according to the filtering result. Among them, the measurement value used for filtering can include the measurement value of the anchor carrier, and can also include the measurement value of the non-anchor carrier. If the measurement value of the non-anchor carrier is included, the measurement value of the non-anchor carrier needs to be converted into the measurement value of the anchor carrier according to the power difference in the above condition 2 before being used for filtering. In addition, the time domain distance between any two measurement values ​​used for filtering needs to be greater than DRX cycle / 2. The time domain distance between two measurement values ​​refers to the duration between the two measurement processes for obtaining the two measurement values.

[0230] According to the above introduction, after obtaining the measurement value of the non-anchor carrier, it needs to be converted into the measurement value of the anchor carrier before it can be used. At present, the conversion process is realized according to the power difference in the above condition 2. However, the power difference is obtained based on the transmission power of the network device, and the measurement value obtained by the terminal device should represent the receiving power. Different carriers may have frequency selectivity. For example, different carriers may have different channel fading characteristics. For two carriers, the difference between the transmission power of the two carriers may not be consistent with the difference between the receiving power of the two carriers. Then, converting the measurement value of the non-anchor carrier according to the power difference will cause the converted measurement value to be inaccurate. Therefore, after obtaining the converted measurement value, the terminal device can determine the difference between the converted measurement value and the measurement value of the anchor carrier. If the difference is large, for example, greater than a certain threshold, the terminal device considers that the measurement value of the non-anchor carrier is unavailable, or that the measurement value of the non-anchor carrier is unreliable.

[0231] Currently, in the discussion of standardization, there is no consensus on what behavior the terminal device will take when the measurement value of the non-anchor carrier is unavailable. One possible implementation is that when the terminal device switches from the anchor carrier to the non-anchor carrier for measurement, if the measurement value obtained from the non-anchor carrier after power difference conversion does not meet the threshold condition with the measurement value of the anchor carrier, the terminal device only uses the measurement value of the non-anchor carrier for filtering.

[0232] If this method is adopted, according to the above introduction, there may be a large frequency selectivity between the non-anchor carrier and the anchor carrier, and the difference between the transmit power of the non-anchor carrier and the anchor carrier may not be consistent with the difference between the receive power of the non-anchor carrier and the anchor carrier. Then, converting the measurement value of the non-anchor carrier according to the power difference will result in the converted measurement value being inaccurate and not actually equivalent to the measurement value of the anchor carrier. If filtering and other operations are performed based on the converted measurement value of the non-anchor carrier, and then determining to start the neighboring cell measurement based on the filtering result, or judging whether the relaxation measurement conditions are met based on the filtering result, etc., the processing result will be inaccurate.

[0233] Alternatively, another possible implementation is that when the terminal device switches from an anchor carrier to a non-anchor carrier for measurement, if the measurement value obtained from the non-anchor carrier after power difference conversion does not meet the threshold condition with the measurement value of the anchor carrier, the terminal device is not allowed to perform measurements on the non-anchor carrier, that is, the terminal device only performs measurements on the anchor carrier.

[0234] The channel conditions of the carrier may not be consistent, and there may be some fluctuations, resulting in errors in the comparison result when comparing the difference between the conversion result of the non-anchor carrier and the measurement value of the anchor carrier with the threshold. Therefore, a comparison result may not truly reflect whether there is a large frequency selectivity between the anchor carrier and the non-anchor carrier. The above method is to determine whether the measurement value of the non-anchor carrier is available based on the comparison result of one measurement, which makes the judgment of whether the measurement value of the non-anchor carrier is available less accurate. Moreover, if the terminal device determines that the measurement value of the non-anchor carrier is not available according to the above implementation method, it will only measure on the anchor carrier. The terminal device also needs to monitor the paging message on the non-anchor carrier, so that within a DRX cycle, the terminal device must not only measure on the anchor carrier, but also switch to the non-anchor carrier to monitor the paging message, which also increases the power consumption of the terminal device.

[0235] In view of this, a technical solution of an embodiment of the present application is provided. In an embodiment of the present application, a first measurement value obtained on a non-anchor carrier can be compared with a second measurement value obtained on an anchor carrier. If the difference is large (i.e., greater than a first threshold), a measurement can be performed on the anchor carrier to obtain a third measurement value, and then the first measurement value is compared with the third measurement value to determine whether the first measurement value is available. This is equivalent to not simply using a single measurement result of an anchor carrier to determine whether the result of a non-anchor carrier is available, but using multiple measurement results of an anchor carrier to determine whether the measurement result of a non-anchor carrier is available, so as to take into account changes in channel conditions as much as possible, reduce the error caused by a single comparison, and improve the accuracy of the judgment result.

[0236] The technical solution provided in the embodiments of the present application can be applied to a fourth generation mobile communication technology (4G) system, such as an LTE system, or can be applied to a 5G system, such as an NR system, or can be applied to a narrowband communication system, such as an NB-IoT system, or can also be applied to a next generation mobile communication system or other similar communication systems, without specific limitation.

[0237] See also Figure 1 , which is an application scenario of an embodiment of the present application. Figure 1 It includes network equipment and terminal equipment. A cell provided by the network equipment is the service cell of the terminal equipment. The network equipment and the terminal equipment can communicate. For example, the network equipment can send a reference signal in the service cell of the terminal equipment, and the terminal equipment can measure the reference signal. The terminal equipment can be a bandwidth-limited terminal equipment, such as an NB-IoT terminal equipment, or a bandwidth-unlimited terminal equipment, or an ordinary terminal equipment.

[0238] The network device, for example, works in an evolved UMTS terrestrial radio access (E-UTRA) system, or works in an NR system, or works in an NB-IoT system, or works in a next generation communication system or other communication systems.

[0239] Figure 1 The network device in the embodiment is, for example, a base station. The network device corresponds to different devices in different systems. For example, in a 4G system, it may correspond to an eNB, and in a 5G system, it may correspond to an access network device in 5G, such as a gNB. Of course, the technical solution provided in the embodiment of the present application can also be applied to future mobile communication systems, so Figure 1 The network devices in the present invention may also correspond to the network devices in future mobile communication systems. Figure 1 Taking the network device as a base station as an example, in fact, referring to the previous introduction, the network device can also be RSU and other devices. In addition, Figure 1 The terminal devices in the description are all mobile phones. In fact, according to the introduction to the terminal devices in the foregoing text, it can be known that the terminal devices in the embodiments of the present application are not limited to mobile phones.

[0240] The method provided by the embodiment of the present application is described below in conjunction with the accompanying drawings. It should be noted that in the various embodiments to be described later in this application, "measurement result" and "measurement value" may be the same concept and the two are interchangeable. For example, the measurement result of an anchor carrier may also be expressed as the measurement value of the anchor carrier; or, the measurement result of a non-anchor carrier may also be expressed as the measurement value of the non-anchor carrier. In addition, for the service cell of the terminal device, one or more non-anchor carriers may be configured, and the non-anchor carrier described later may refer to one of the one or more non-anchor carriers.

[0241] The present application embodiment provides a first communication method, see Figure 2 , which is a flowchart of the method. In the following introduction, the method is applied to Figure 1 The network architecture shown is taken as an example.

[0242] For the sake of convenience, the following takes the method executed by a network device and a terminal device as an example. Figure 1 The network architecture shown in FIG. 1 is taken as an example, therefore, the network devices described below may be Figure 1 The network device in the network architecture shown in the figure, the terminal device described below can be Figure 1 Terminal devices in the network architecture shown.

[0243] S21. The terminal device measures the anchor carrier of the service cell of the terminal device to obtain a second measurement value.

[0244] In an embodiment of the present application, the service cell of the terminal device is configured with an anchor carrier and one or more non-anchor carriers. After the anchor carrier is configured, the terminal device can perform measurements on the anchor carrier when it needs to perform measurements on the anchor carrier. For example, the terminal device receives a first reference signal from a network device on the anchor carrier, the first reference signal is, for example, NRS or NSSS, and the terminal device measures the received first reference signal, for example, to obtain a second measurement value. The second measurement value is, for example, NRSRP or NRSRQ.

[0245] S22. The terminal device performs measurement on a non-anchor carrier of a serving cell of the terminal device to obtain a first measurement value.

[0246] If the terminal device determines that the non-anchor carrier measurement conditions are met, the measurement can be performed on the non-anchor carrier, or it can also be measured on the anchor carrier. The non-anchor carrier may be one of the one or more non-anchor carriers of the service cell of the terminal device. For example, the terminal device chooses to measure on the non-anchor carrier. Specifically, the terminal device receives a second reference signal from the network device on the anchor carrier. The second reference signal is, for example, NRS, etc. The terminal device measures the received second reference signal to obtain a first measurement value. The first measurement value may be, for example, NRSRP or NRSRQ. The first measurement value and the second measurement value may be values ​​of the same type, for example, both are NRSRP or both are NRSRQ.

[0247] The non-anchor carrier measurement conditions may include, for example, three conditions: 1. The relaxed measurement conditions are satisfied; 2. The power difference between the power of the NRS of the non-anchor carrier and the power of the NRS of the anchor carrier is known to the terminal device; 3. The terminal device is not configured for positioning measurement. For details about the non-anchor carrier measurement conditions, please refer to the previous introduction.

[0248] For example, S21 may be executed before S22, or S21 may be executed after S22, or S21 and S22 may be executed simultaneously.

[0249] S23. The terminal device obtains a first conversion value according to the first measurement value and the first difference.

[0250] The first difference may indicate the power difference between the non-anchor carrier and the anchor carrier, or the first difference is the power difference between the non-anchor carrier and the anchor carrier. The power difference may come from the network device, for example, before S23, the network device sends the first difference to the terminal device, and the terminal device receives the first difference from the network device. The power difference may be obtained by the network device according to the transmit power of the signal sent to the anchor carrier and the transmit power of the signal sent to the non-anchor carrier, that is, the transmit power of the signal sent by the network device to the anchor carrier and the transmit power of the signal sent by the network device to the non-anchor carrier are both known to the network device, and the difference between the two transmit powers can be used as the first difference.

[0251] The first measurement value obtained by the terminal device is the measurement value of the non-anchor carrier. To use the measurement value of the non-anchor carrier, it needs to be converted to be equivalent to the measurement value of the anchor carrier before it can be used, for example, it can be used to determine whether the relaxation measurement conditions are met. When converting the measurement value of the non-anchor carrier, the first difference can be used, or the first measurement value can be converted according to the first difference. The value obtained after the conversion is called the first conversion value. The conversion value in the embodiment of the present application refers to the measurement value equivalent to the measurement on the anchor carrier obtained by conversion or calculation (for example, the NRSRP equivalent to the measurement on the anchor carrier obtained by conversion or calculation). Alternatively, the conversion value can also be called an equivalent value, or it can have other names. That is, the terminal device can obtain the first conversion value based on the first measurement value and the first difference. For example, the terminal device can add the first measurement value to the first difference, and the sum obtained is the first conversion value; or the terminal device can subtract the first measurement value from the first difference, and the difference obtained is the first conversion value. Among them, if the terminal device uses the difference obtained by subtracting the first measurement value from the first difference as the first conversion value, then the first conversion value can be the actual value of the first measurement value minus the first difference, or the actual value of the first difference minus the first measurement value, or the absolute value of the difference between the first measurement value and the first difference.

[0252] S24: The terminal device determines whether the difference between the first conversion value and the second measurement value (or the absolute value of the difference) is greater than a first threshold.

[0253] Among them, the second measurement value is the measurement value obtained by the terminal device in S21 at the anchor carrier. As an optional implementation, the measurement process in which the terminal device obtains the second measurement value (or the measurement process corresponding to the second measurement value) and the measurement process in which the terminal device obtains the first measurement value (or the measurement process corresponding to the first measurement value) can be measurement processes that are adjacent in time. Or it can also be understood that before executing S24, the terminal device can first determine whether the measurement process in which the terminal device obtains the second measurement value and the measurement process in which the terminal device obtains the first measurement value are adjacent measurement processes. If the two measurement processes are adjacent measurement processes, the terminal device can execute S24, and if the two measurement processes are not adjacent measurement processes, the terminal device may not have to execute S24. For example, the terminal device may consider that the first conversion value is available, or consider that the first measurement value is available, and the terminal device can directly use the first conversion value, for example, filtering according to the first conversion value.

[0254] Because the terminal device needs to determine whether the first measurement value is available based on the second measurement value, if the interval between the acquisition time of the first measurement value and the acquisition time of the second measurement value is long, the second measurement value may not be accurate enough and cannot reflect the current quality of the anchor carrier. If the first measurement value is judged to be available based on such a second measurement value, the judgment result may be inaccurate. If the measurement process in which the terminal device obtains the second measurement value is adjacent to the measurement process in which the terminal device obtains the first measurement value, it means that the interval between the acquisition time of the first measurement value and the acquisition time of the second measurement value is short, and the second measurement value can reflect the current quality of the anchor carrier. Judging whether the first measurement value is available based on such a second measurement value can improve the accuracy of the judgment result.

[0255] If the terminal device determines that the difference between the first conversion value and the second measurement value is less than or equal to the first threshold, the terminal device can determine that the first conversion value is available, or that the first measurement value is available. Then the process can end, for example, the terminal device can use the first conversion value, such as filtering according to the first conversion value. If the terminal device determines that the difference between the first conversion value and the second measurement value is greater than the first threshold, S25 can be continued.

[0256] The first threshold may be set by the network device, and the network device may send it to the terminal device in advance, so that the terminal device can know the first threshold. Alternatively, the first threshold may also be specified by the protocol. Alternatively, the first threshold may also be preconfigured in the terminal device.

[0257] S25. The terminal device performs measurement on the anchor carrier to obtain a third measurement value.

[0258] In an embodiment of the present application, if the terminal device determines that the difference between the first conversion value and the second measurement value is greater than the first threshold, then when the next DRX cycle that needs to be measured arrives, the terminal device can perform measurements on the anchor carrier. It can be understood that there are generally no restrictions on the measurement behavior of the terminal device. If the non-anchor carrier measurement conditions are not met, the terminal device can perform measurements on the anchor carrier. If the non-anchor carrier measurement conditions are met, the terminal device can perform measurements on the anchor carrier or on the non-anchor carrier. However, if the terminal device determines that the difference between the first conversion value and the second measurement value is greater than the first threshold, the terminal device can perform measurements on the anchor carrier and then obtain the measurement value of the anchor carrier.

[0259] If S21 can be executed after S22 , then S21 can be executed before S25 , or S21 can be executed after S25 .

[0260] S26. The terminal device determines whether the first measurement value is available according to the third measurement value. Or rather, the terminal device determines whether the first conversion value is available according to the third measurement value.

[0261] After obtaining the third measurement value, the terminal device can determine whether the first measurement value is available according to the third measurement value. For example, the terminal device calculates the difference between the first conversion value and the third measurement value. If this difference (or the absolute value of this difference) is less than or equal to the first threshold, then although the difference between the first conversion value and the second measurement value is greater than the first threshold, since the difference between the first conversion value and the second measurement value is less than or equal to the first threshold, the terminal device can determine that the first conversion value is available, or rather determine that the first measurement value is available. If the difference between the first conversion value and the third measurement value is greater than the first threshold, then the terminal device can determine that the first conversion value is unavailable, or rather determine that the first measurement value is unavailable.

[0262] For example, reference can be made to Figure 3 , Figure 3 , where NRSRP1 corresponding to the second measurement value can represent the second measurement value, and NRSRP2 represents the first measurement value. If the difference between the first conversion value corresponding to the second measurement value and the second measurement value is greater than the first threshold, then the terminal device can perform measurement on the anchor carrier to obtain the third measurement value, NRSRP3 represents the third measurement value, and the terminal device can then determine whether the first measurement value is available according to the third measurement value. Figure 3 Taking the case where NRSRP2 is unavailable as an example, that is, Figure 3 the "×" in the box of NRSRP2 in

[0263] In the embodiments of the present application, the measurement value is available, which may include one or more of the following situations: the converted value corresponding to the measurement value can be used for filtering, the converted value corresponding to the measurement value can be used for enabling neighbor cell measurement, and the converted value corresponding to the measurement value can be used for determining relaxation of measurement conditions. For example, when the first measurement value is available, it may include one or more of the following situations: the first converted value can be used for filtering, the first converted value can be used for enabling neighbor cell measurement, and the first converted value can be used for determining relaxation of measurement conditions. For example, when the first measurement value is available, it may include that the first converted value can be used for filtering; or, when the first measurement value is available, it may include that the first converted value can be used for enabling neighbor cell measurement; or, when the first measurement value is available, it may include that the first converted value can be used for determining relaxation of measurement conditions; or, when the first measurement value is available, it may include that the first converted value can be used for filtering and the first converted value can be used for enabling neighbor cell measurement; or, when the first measurement value is available, it may include that the first converted value can be used for filtering and the first converted value can be used for determining relaxation of measurement conditions; or, when the first measurement value is available, it may include that the first converted value can be used for enabling neighbor cell measurement and the first converted value can be used for determining relaxation of measurement conditions; or, when the first measurement value is available, it may include that the first converted value can be used for filtering, the first converted value can be used for enabling neighbor cell measurement, and the first converted value can be used for determining relaxation of measurement conditions. Of course, the availability of the measurement value may also include other situations, or may not include the above three situations, but include other situations, which are not limited in the embodiments of the present application.

[0264] Among them, both S25 and S26 are optional steps and do not have to be executed. Therefore, they are represented by dashed lines in Figure 2 the figure.

[0265] In the embodiments of the present application, the terminal device may compare the first measurement value obtained on the non-anchor carrier with the second measurement value obtained on the anchor carrier. If the difference is large (i.e., greater than the first threshold), the terminal device may further perform measurement on the anchor carrier to obtain a third measurement value, and then compare the first measurement value with the third measurement value to determine whether the first measurement value is available. Equivalently, instead of simply using the measurement result of the anchor carrier once to determine whether the result of the non-anchor carrier is available, multiple measurement results of the anchor carrier can be used to determine whether the measurement result of the non-anchor carrier is available, so as to consider situations such as channel condition changes as much as possible, reduce the error caused by one comparison, and improve the accuracy of the judgment result.

[0266] An embodiment of the present application is equivalent to defining a behavior of a terminal device, that is, which measurement results of an anchor carrier are used by the terminal device to determine whether the measurement results of a non-anchor carrier meet the threshold condition. The terminal device may perform multiple measurements on the anchor carrier. When it is necessary to determine whether the measurement results of the non-anchor carrier meet the threshold condition, it is necessary to clarify which measurement results of the anchor carrier the measurement results of the non-anchor carrier are compared with. Then, the embodiment of the present application provides a behavior mode of the terminal device, using multiple measurement results of the anchor carrier to determine whether the measurement results of the non-anchor carrier meet the threshold condition, and the measurement processes corresponding to these multiple measurement results are adjacent to the measurement process corresponding to the measurement results of the non-anchor carrier, so that the acquisition times of these measurement results are relatively close, improving the accuracy of the judgment result.

[0267] In the embodiment of the present application, if the terminal device determines that the first measurement value is unavailable, then next, the terminal device may continue to perform measurements on the non-anchor carrier, or return to the anchor carrier for measurement, that is, there is no restriction on the subsequent measurement behavior of the terminal device, and the terminal device can determine by itself. Or, if the terminal device determines that the first measurement value is unavailable, then within the second time period, the terminal device may also only perform measurements on the anchor carrier. That is to say, if it is determined that the first measurement value is unavailable, it indicates that the measurement results of the non-anchor carrier may be unreliable. In this case, the terminal device may also only perform measurements on the anchor carrier within a certain time to improve the accuracy of the obtained measurement results. This is equivalent to defining another behavior of the terminal device, that is, whether the terminal device can continue to perform measurements on the non-anchor carrier after the measurement results of the non-anchor carrier are determined to be unavailable in a certain determination. The embodiment of the present application provides several behavior modes of the terminal device, that is, when the measurement results of the non-anchor carrier are determined to be unavailable in a certain determination, there is no restriction on the measurement behavior of the terminal device, and the terminal device can perform measurements on the non-anchor carrier or on the anchor carrier; or, when the measurement results of the non-anchor carrier are determined to be unavailable in a certain determination, the terminal device may also only perform measurements on the anchor carrier for a period of time. It can be seen that the embodiment of the present application standardizes the measurement behavior of the terminal device in various ways.

[0268] As an alternative implementation, there is another behavior of the terminal device that can be specified, that is, whether the terminal device still allows measurement on the non-anchor carrier after determining that the measurement results of the non-anchor carrier are unavailable multiple times. For this purpose, the embodiments of this application propose that if the terminal device determines that the measurement values obtained from measuring on the non-anchor carrier for K consecutive times are all unavailable, the terminal device measures only on the anchor carrier within the first time period, where K is an integer greater than or equal to 1. K can be configured by the network device, or pre-configured in the terminal device, or can also be specified by the protocol. The first time period can be configured by the network device, or pre-configured in the terminal device, or can also be specified by the protocol. The first time period can be an absolute time length, such as 100 seconds, etc.; or, the first time period can also be a relative time length, for example, the unit of the first time period is the DRX cycle, or it can also be other units. For example, if the first time period specified by the protocol is the length of 3 DRX cycles, this means that if the measurement values obtained from measuring on the non-anchor carrier for K consecutive times are all unavailable, then within the next 3 DRX cycles, the terminal device measures only on the anchor carrier.

[0269] Among them, these K measurement processes can be pairwise adjacent measurement processes, that is, the terminal device has performed K measurement processes during this period, and all K measurement processes are measurement processes on the non-anchor carrier; or, these K measurement processes may not be pairwise adjacent measurement processes. For example, the i-th measurement process and the (i + 1)-th measurement process among the K measurement processes are non-adjacent measurement processes. This can be understood as follows: The terminal device has performed a total of K + P measurement processes during this period, where K measurement processes are measurement processes on the non-anchor carrier, and P measurement processes are measurement processes on the anchor carrier, and the measurement processes on the anchor carrier and the measurement processes on the non-anchor carrier may be interleaved. For example, the j-th measurement process among the K + P measurement processes is a measurement process on the anchor carrier, and the (j + 1)-th measurement process is a measurement process on the non-anchor carrier. If this is the case, then for two consecutive measurement processes on the non-anchor carrier, even if there is an intervening measurement process on the anchor carrier in between, it is considered that the two consecutive measurement processes on the non-anchor carrier are continuous because they are both measurement processes on the non-anchor carrier.

[0270] For example, reference can be made to Figure 4, the terminal device measures NRSRP1 on the anchor carrier. After that, if the terminal device determines that the non-anchor carrier measurement condition is met, the terminal device measures NRSRP2 on the non-anchor carrier. For example, if the difference between the converted value corresponding to NRSRP2 and NRSRP1 is greater than the first threshold, the terminal device continues to measure on the anchor carrier and obtains NRSRP3. For example, if the difference between the converted value corresponding to NRSRP2 and NRSRP3 is also greater than the first threshold, the terminal device determines that NRSRP2 is unavailable. Then, for example, the terminal device measures NRSR4 on the non-anchor carrier again. In a similar manner, the terminal device determines that NRSRP4 is unavailable based on NRSRP3 and NRSRP5 obtained by measuring on the anchor carrier. For example, if K = 2, it means that the measurement values obtained by measuring on the non-anchor carrier continuously for two times are both unavailable. Then, within the first time period, the terminal device only measures on the anchor carrier. For example Figure 4 The first time period is denoted as T. Within the time period T, the terminal device only measures on the anchor carrier and obtains (x - 5) NRSRPs such as NRSRP6 to NRSRP x.

[0271] If the measurement values obtained by measuring on the non-anchor carrier continuously for K times are all unavailable, it indicates that the measurement results of the non-anchor carrier have a large deviation from those of the anchor carrier within a certain period of time. In this case, the terminal device can measure only on the anchor carrier for a certain period of time to reduce the error caused by continuing to measure on the non-anchor carrier. Optionally, after the first time period, the terminal device can continue to measure on the anchor carrier, or if the non-anchor carrier measurement condition is still met, the terminal device can also measure on the non-anchor carrier. This makes the measurement of the terminal device more flexible, avoiding the error caused by inter-carrier frequency selectivity while maximizing the flexibility of the terminal device in selecting measurements between carriers and reducing unnecessary power consumption.

[0272] In addition, as another optional implementation, there is also a behavior of the terminal device that can be clarified, that is, how to ensure the reliability of the measurement result of the anchor carrier when the terminal device measures on the non-anchor carrier. For example, when determining whether the measurement result of the non-anchor carrier is available, the measurement result of the anchor carrier is used. If the time interval between the acquisition time of the measurement result of the anchor carrier and the acquisition time of the measurement result of the non-anchor carrier is relatively long, the measurement result of the anchor carrier may not be accurate enough. Using this measurement result of the anchor carrier to determine whether the measurement result of the non-anchor carrier is available will also result in an inaccurate determination result. Therefore, the embodiment of the present application proposes that the terminal device can regularly measure on the anchor carrier, so as to determine whether the measurement result of the non-anchor carrier is available based on the recent measurement result of the anchor carrier as much as possible, improving the accuracy of the determination result.

[0273] For example, the terminal device can perform measurements once every M DRX cycles. The measurements can be performed on the anchor carrier or on a non-anchor carrier. M can be an integer greater than or equal to 1. M can be configured by the network device, pre-configured in the terminal device, or specified by the protocol. For example, if M = 1, the terminal device needs to perform measurements in each DRX cycle. For example, continuing to refer to Figure 3 , if the terminal device obtains NRSRP1 after one measurement and NRSRP2 after the next measurement, these two measurement processes are adjacent. If it obtains NRSRP3 after another measurement, these three measurement processes are pairwise adjacent. If M = 1, the terminal device measures and obtains NRSRP1 within the first DRX cycle, measures and obtains NRSRP2 within the next DRX cycle (or the second DRX cycle), and measures and obtains NRSRP3 within the next DRX cycle (or the third DRX cycle). If M > 1, taking M = 2 as an example, the terminal device measures once every two DRX cycles. For example, the terminal device measures and obtains NRSRP1 within the first DRX cycle, measures and obtains NRSRP2 within the third DRX cycle, and measures and obtains NRSRP3 within the fifth DRX cycle.

[0274] Then, in the embodiments of this application, it is stipulated that within every M×N DRX cycles, the terminal device can perform at least one measurement on the anchor carrier. N can be configured by the network device, pre-configured in the terminal device, or specified by the protocol. This can also be understood as that within every N consecutive measurement processes, at least one measurement process performed on the anchor carrier can be included. For example, if M = 1, then within every N DRX cycles, the terminal device can perform at least one measurement on the anchor carrier. Or rather, within every N consecutive measurement processes, at least one measurement process performed on the anchor carrier can be included. Another example is that if M = 2, then within every 2N DRX cycles, the terminal device can perform at least one measurement on the anchor carrier. Or rather, within every 2N consecutive measurement processes, at least one measurement process performed on the anchor carrier can be included.

[0275] For example, referring to Figure 5 , taking M = 1 and N = 4 as an example. That is to say, the terminal device will perform measurements in each DRX cycle. Within every 4 DRX cycles, the terminal device can perform at least one measurement on the anchor carrier, and Figure 5 taking the example that the terminal device can perform one measurement on the anchor carrier within every 4 DRX cycles. Figure 5In the method, in the first DRX cycle, the terminal device measures on the anchor carrier to obtain NRSRP1; in the second DRX cycle, the terminal device measures on a non-anchor carrier to obtain NRSRP2; in the third DRX cycle, the terminal device measures on a non-anchor carrier to obtain NRSRP3; in the fourth DRX cycle, the terminal device measures on a non-anchor carrier to obtain NRSRP4; in the fifth DRX cycle, the terminal device returns to measure on a non-anchor carrier to obtain NRSRP5; in the sixth DRX cycle, the terminal device measures on a non-anchor carrier to obtain NRSRP6; in the seventh DRX cycle, the terminal device measures on a non-anchor carrier to obtain NRSRP7; in the eighth DRX cycle, the terminal device measures on a non-anchor carrier to obtain NRSRP8, and so on.

[0276] In addition, Figure 5 In the method, NRSRP1 and NRSRP2 are circled together because the measurement processes for obtaining NRSRP1 and NRSRP2 are adjacent measurement processes. Therefore, for NRSRP2, it can be determined whether NRSRP2 is available based on NRSRP1. For NRSRP3 and NRSRP4, since the measurement processes for obtaining NRSRP3 and NRSRP4 are not adjacent to the measurement process for obtaining NRSRP1, the terminal device does not need to determine whether NRSRP3 is available based on NRSRP1, but can determine that NRSRP3 is available without judgment. Similarly, the terminal device does not need to determine whether NRSRP4 is available based on NRSRP1, but can determine that NRSRP4 is available without judgment. Figure 5 The same meaning applies to circling NRSRP5 and NRSRP6 together, which will not be elaborated here.

[0277] In the embodiment of the present application, the terminal device may compare a first measurement value obtained on a non-anchor carrier with a second measurement value obtained on an anchor carrier. If the difference is large (i.e., greater than a first threshold), the terminal device may further measure on the anchor carrier to obtain a third measurement value, and then compare the first measurement value with the third measurement value to determine whether the first measurement value is available. This is equivalent to not simply using the measurement result of the anchor carrier once to determine whether the result of the non-anchor carrier is available, but using multiple measurement results of the anchor carrier to determine whether the measurement result of the non-anchor carrier is available, so as to consider the change of the channel condition as much as possible, reduce the error caused by one comparison, and improve the accuracy of the judgment result.

[0278] Moreover, if the measurement values obtained from consecutive K measurements on the non-anchor carrier are all unavailable, it indicates that the measurement results of the non-anchor carrier have a large deviation from those of the anchor carrier over a period of time. In this case, the terminal device can measure only on the anchor carrier for a period of time, thereby reducing the error caused by continuing to measure on the non-anchor carrier.

[0279] In addition, the terminal device can periodically measure on the anchor carrier, so as to determine whether the measurement result of the non-anchor carrier is available based on the recent measurement results on the anchor carrier as much as possible, avoid too long an interval between the acquisition time of the measurement result of the non-anchor carrier and the acquisition time of the measurement result of the anchor carrier, and improve the accuracy of the determination result.

[0280] Next, consider another problem. When the terminal device determines whether the measurement result of the non-anchor carrier is available, it uses the measurement result of the anchor carrier. If the time interval between the acquisition time of the measurement result of the anchor carrier and the acquisition time of the measurement result of the non-anchor carrier is relatively long, the measurement result of the anchor carrier may not be accurate enough. Using this measurement result of the anchor carrier to determine whether the measurement result of the non-anchor carrier is available will also result in an inaccurate determination result. Therefore, the second communication method provided by the embodiments of the present application is that the terminal device can periodically measure on the anchor carrier, so as to determine whether the measurement result of the non-anchor carrier is available based on the recent measurement results on the anchor carrier as much as possible, and improve the accuracy of the determination result. Please refer to Figure 6 , which is the flowchart of this method. In the following introduction, this method is applied to Figure 1 the network architecture shown as an example.

[0281] For the convenience of introduction, in the following, this method is taken as an example of being executed by a network device and a terminal device. Since this embodiment is based on the network architecture shown in Figure 1 as an example, therefore, the network device described below can be the network device in the network architecture shown in Figure 1 the network architecture shown, and the terminal device described below can be the terminal device in the network architecture shown in Figure 1 the network architecture shown.

[0282] S61. In every M×N DRX cycles, the terminal device performs at least one measurement on the anchor carrier of the serving cell of the terminal device.

[0283] In the embodiments of the present application, the serving cell of the terminal device is configured with one anchor carrier and one or more non-anchor carriers.

[0284] For example, the terminal device may perform a measurement every M DRX cycles, and the measurement may be performed on the anchor carrier or on a non-anchor carrier. M may be an integer greater than or equal to 1. M may be configured by the network device, pre-configured in the terminal device, or may also be specified by the protocol. For example, if M = 1, the terminal device needs to perform a measurement every DRX cycle. For example, continuing to refer to Figure 3 , the terminal device obtains NRSRP1 after performing one measurement, obtains NRSRP2 after performing the next measurement, and these two measurement processes are adjacent. Obtaining NRSRP3 is after performing another measurement, and these three measurement processes are pairwise adjacent. If M = 1, the terminal device measures and obtains NRSRP1 within the first DRX cycle, measures and obtains NRSRP2 within the next DRX cycle (or the second DRX cycle), and measures and obtains NRSRP3 within the next DRX cycle (or the third DRX cycle). If M > 1, taking M = 2 as an example, the terminal device measures once every two DRX cycles. For example, the terminal device measures and obtains NRSRP1 within the first DRX cycle, measures and obtains NRSRP2 within the third DRX cycle, and measures and obtains NRSRP3 within the fifth DRX cycle.

[0285] Then, the embodiments of the present application stipulate that within every M×N DRX cycles, the terminal device may perform at least one measurement on the anchor carrier. N may be configured by the network device, pre-configured in the terminal device, or may also be specified by the protocol. This can also be understood as that within every N consecutive measurement processes, it may include at least one measurement process performed on the anchor carrier. For example, if M = 1, then within every N DRX cycles, the terminal device may perform at least one measurement on the anchor carrier, or in other words, within every N consecutive measurement processes, it may include at least one measurement process performed on the anchor carrier. Another example is that if M = 2, then within every 2N DRX cycles, the terminal device may perform at least one measurement on the anchor carrier, or in other words, within every 2N consecutive measurement processes, it may include at least one measurement process performed on the anchor carrier.

[0286] Reference may be made to Figure 5 , taking M = 1 and N = 4 as an example. That is to say, the terminal device will perform a measurement every DRX cycle, and within every 4 DRX cycles, the terminal device may perform at least one measurement on the anchor carrier, and Figure 5 taking the example that within every 4 DRX cycles, the terminal device may perform one measurement on the anchor carrier. Figure 5Among them, in the first DRX cycle, the terminal device measures on the anchor carrier to obtain NRSRP1; in the second DRX cycle, the terminal device measures on the non-anchor carrier to obtain NRSRP2; in the third DRX cycle, the terminal device measures on the non-anchor carrier to obtain NRSRP3; in the fourth DRX cycle, the terminal device measures on the non-anchor carrier to obtain NRSRP4; in the fifth DRX cycle, the terminal device returns to measure on the non-anchor carrier to obtain NRSRP5; in the sixth DRX cycle, the terminal device measures on the non-anchor carrier to obtain NRSRP6; in the seventh DRX cycle, the terminal device measures on the non-anchor carrier to obtain NRSRP7; in the eighth DRX cycle, the terminal device measures on the non-anchor carrier to obtain NRSRP8, and so on.

[0287] In the embodiment of the present application, the terminal device can regularly measure on the anchor carrier, so as to determine whether the measurement result of the non-anchor carrier is available according to the measurement result on the anchor carrier recently as much as possible, avoid the interval between the acquisition time of the measurement result of the non-anchor carrier and the acquisition time of the measurement result of the anchor carrier from being too long, and improve the accuracy of the determination result.

[0288] S62. The terminal device measures on the anchor carrier of the serving cell of the terminal device to obtain a second measurement value. Among them, S62 may include S61, that is, S62 and S61 may be the same step, or may also be different steps respectively. In addition, Figure 6 The execution order of S61 and S62-S67 shown is only an example. In fact, there is no fixed order limit for S61 and S62-S67. For example, S61 may also occur after S62-S67, or S61 may also occur simultaneously with S62-S67. For example, S61 may be executed simultaneously with a certain step in S62-S67, etc.

[0289] For more content about S62, reference can be made to Figure 2 the introduction of S21 in the embodiment shown.

[0290] S63. The terminal device measures on the non-anchor carrier of the serving cell of the terminal device to obtain a first measurement value.

[0291] If the terminal device determines that the non-anchor carrier measurement condition is met, it can measure on the non-anchor carrier, or it can also measure on the anchor carrier. The non-anchor carrier mentioned above may be one of one or more non-anchor carriers of the serving cell of the terminal device. For example, the terminal device selects to measure on the non-anchor carrier to obtain a first measurement value.

[0292] For more content about S63, reference can be made to Figure 2 the introduction of S22 in the embodiment shown.

[0293] S64. The terminal device obtains a first conversion value based on the first measurement value and the first difference.

[0294] The first difference may indicate the power difference between the non-anchor carrier and the anchor carrier, or rather, the first difference is the power difference between the non-anchor carrier and the anchor carrier. This power difference may come from the network device. For example, before S64, the network device sends the first difference to the terminal device, and the terminal device receives the first difference from the network device. This power difference may be obtained by the network device based on the transmission power of the signal sent to the anchor carrier and the transmission power of the signal sent to the non-anchor carrier. That is, the transmission power of the signal sent by the network device to the anchor carrier and the transmission power of the signal sent by the network device to the non-anchor carrier are both known to the network device, and the difference between these two transmission powers can be used as the aforementioned first difference.

[0295] For example, the terminal device may add the first measurement value and the first difference, and the resulting sum value is the first conversion value; or, the terminal device may subtract the first difference from the first measurement value, and the resulting difference value is the first conversion value. Among them, if the terminal device subtracts the first difference from the first measurement value to obtain the difference value as the first conversion value, then the first conversion value may take the actual value of the first measurement value minus the first difference, or take the actual value of the first difference minus the first measurement value, or take the absolute value of the difference between the first measurement value and the first difference.

[0296] For more content about S64, reference can be made to Figure 2 the description of the embodiment shown for S23.

[0297] S65. The terminal device determines whether the difference (or the absolute value of the difference) between the first conversion value and the second measurement value is greater than the first threshold.

[0298] If the terminal device determines that the difference between the first conversion value and the second measurement value is less than or equal to the first threshold, then the terminal device may determine that the first conversion value is available, or rather, determine that the first measurement value is available. Then the process may end. For example, the terminal device may utilize the first conversion value, such as performing filtering based on the first conversion value. If the terminal device determines that the difference between the first conversion value and the second measurement value is greater than the first threshold, then S66 may be continued to be executed.

[0299] For more content about S65, reference can be made to Figure 2 the description of the embodiment shown for S24.

[0300] S66. The terminal device performs measurement on the anchor carrier to obtain a third measurement value.

[0301] In an embodiment of the present application, if the terminal device determines that the difference between the first conversion value and the second measurement value is greater than the first threshold, then when the next DRX cycle to be measured arrives, the terminal device may perform measurement on the anchor carrier.

[0302] For more content about S66, reference can be made to Figure 2 the description of the embodiment shown for S25.

[0303] S67. The terminal device determines whether the first measurement value is available according to the third measurement value. Or rather, the terminal device determines whether the first conversion value is available according to the third measurement value.

[0304] After obtaining the third measurement value, the terminal device can determine whether the first measurement value is available according to the third measurement value. For example, the terminal device calculates the difference between the first conversion value and the third measurement value. If this difference (or the absolute value of this difference) is less than or equal to the first threshold, then although the difference between the first conversion value and the second measurement value is greater than the first threshold, since the difference between the first conversion value and the second measurement value is less than or equal to the first threshold, the terminal device can determine that the first conversion value is available, or rather determine that the first measurement value is available. And if the difference between the first conversion value and the third measurement value is greater than the first threshold, then the terminal device can determine that the first conversion value is unavailable, or rather determine that the first measurement value is unavailable.

[0305] For more content about S67, reference can be made to Figure 2 the description of the embodiment shown for S26. Among them, S62 to S67 are all optional steps and are not necessarily executed, and are indicated by dashed lines in Figure 6 it.

[0306] As an alternative implementation, there is another behavior of the terminal device that can be clarified, that is, whether the terminal device still allows measurement on the non-anchor carrier after determining that the measurement results of the non-anchor carrier are unavailable multiple times. For this purpose, the embodiments of this application propose that if the terminal device determines that the measurement values obtained from measuring on the non-anchor carrier for K consecutive times are all unavailable, the terminal device only measures on the anchor carrier within the first time period, where K is an integer greater than or equal to 1. K can be configured by the network device, or pre-configured in the terminal device, or can also be specified by the protocol. The first time period can be configured by the network device, or pre-configured in the terminal device, or can also be specified by the protocol. The first time period can be an absolute time length, such as 100 seconds, etc.; or, the first time period can also be a relative time length, for example, the unit of the first time period is the DRX cycle, or it can also be other units. For example, if the first time period specified by the protocol is the length of 3 DRX cycles, this means that if the measurement values obtained from measuring on the non-anchor carrier for K consecutive times are all unavailable, within the next 3 DRX cycles, the terminal device only measures on the anchor carrier.

[0307] Among them, these K measurement processes can be pairwise adjacent measurement processes, that is, the terminal device has performed K measurement processes in this period of time, and all K measurement processes are measurement processes on the non-anchor carrier; or, these K measurement processes may not be pairwise adjacent measurement processes. For example, the i-th measurement process and the (i + 1)-th measurement process among the K measurement processes are non-adjacent measurement processes. This can be understood as follows: the terminal device has performed a total of K + P measurement processes in this period of time, where K measurement processes are measurement processes on the non-anchor carrier, and P measurement processes are measurement processes on the anchor carrier, and the measurement processes on the anchor carrier and the measurement processes on the non-anchor carrier may be interleaved. For example, the j-th measurement process among the K + P measurement processes is a measurement process on the anchor carrier, and the (j + 1)-th measurement process is a measurement process on the non-anchor carrier. If this is the case, for two consecutive measurement processes on the non-anchor carrier, even if there is an intervening measurement process on the anchor carrier in between, it is considered that the two consecutive measurement processes on the non-anchor carrier are continuous because they are both measurement processes on the non-anchor carrier.

[0308] For example, reference can be made to Figure 4, the terminal device measures NRSRP1 on the anchor carrier. After that, if the terminal device determines that the non-anchor carrier measurement condition is met, the terminal device measures NRSRP2 on the non-anchor carrier. For example, if the difference between the converted value corresponding to NRSRP2 and NRSRP1 is greater than the first threshold, the terminal device continues to measure on the anchor carrier and obtains NRSRP3. For example, if the difference between the converted value corresponding to NRSRP2 and NRSRP3 is also greater than the first threshold, the terminal device determines that NRSRP2 is unavailable. Then, for example, the terminal device measures NRSR4 on the non-anchor carrier again. In a similar manner, the terminal device determines that NRSRP4 is unavailable based on NRSRP3 and NRSRP5 measured on the anchor carrier. For example, if K = 2, then the measurement values obtained from two consecutive measurements on the non-anchor carrier are both unavailable. In this case, the terminal device only measures on the anchor carrier within the first time period. For example Figure 4 The first time period is denoted as T. Within the T time period, the terminal device only measures on the anchor carrier and obtains (x - 5) NRSRPs such as NRSRP6 to NRSRPx.

[0309] If the measurement values obtained from K consecutive measurements on the non-anchor carrier are all unavailable, it indicates that there is a large deviation between the measurement results of the non-anchor carrier and the measurement results of the anchor carrier over a period of time. In this case, the terminal device can measure only on the anchor carrier for a period of time to reduce the error caused by continuing to measure on the non-anchor carrier. Optionally, after the first time period, the terminal device can continue to measure on the anchor carrier, or if the non-anchor carrier measurement condition is still met, the terminal device can also measure on the non-anchor carrier. This makes the measurement of the terminal device more flexible, avoiding the error caused by inter-carrier frequency selectivity while maximizing the flexibility of the terminal device in selecting measurements between carriers and reducing unnecessary power consumption.

[0310] In the embodiment of the present application, the terminal device can regularly measure on the anchor carrier to determine whether the measurement result of the non-anchor carrier is available based on the recent measurement result on the anchor carrier as much as possible, avoiding too long an interval between the acquisition time of the measurement result of the non-anchor carrier and the acquisition time of the measurement result of the anchor carrier, and improving the accuracy of the determination result.

[0311] Moreover, the terminal device can compare the first measurement value obtained on the non-anchor carrier with the second measurement value obtained on the anchor carrier. If the difference is large (i.e., greater than the first threshold), the terminal device can also measure on the anchor carrier again to obtain a third measurement value, and then compare the first measurement value with the third measurement value to determine whether the first measurement value is available. Instead of simply using the measurement result of the anchor carrier once to determine whether the result of the non-anchor carrier is available, multiple measurement results of the anchor carrier can be used to determine whether the measurement result of the non-anchor carrier is available, so as to consider the change of the channel condition as much as possible, reduce the error caused by one comparison, and improve the accuracy of the judgment result.

[0312] In addition, if the measurement values obtained by continuously measuring on the non-anchor carrier for K times are all unavailable, it indicates that the measurement results of the non-anchor carrier have a large deviation from those of the anchor carrier within a period of time. In this case, the terminal device can measure only on the anchor carrier for a period of time, thereby reducing the error caused by continuing to measure on the non-anchor carrier.

[0313] Next, consider another problem. If the terminal device continues to measure on the non-anchor carrier after determining that the measurement results of the non-anchor carrier are unavailable multiple times, it may cause the measurement results to be inaccurate all the time. For this reason, the embodiment of the present application provides a third communication method. In this method, if the terminal device determines that the measurement values obtained by continuously measuring on the non-anchor carrier for K times are all unavailable, the terminal device measures only on the anchor carrier within the first time period, where K is an integer greater than or equal to 1. K can be configured by the network device, or pre-configured in the terminal device, or can also be specified by the protocol. The first time period can be configured by the network device, or pre-configured in the terminal device, or can also be specified by the protocol. Please refer to Figure 7 , which is the flowchart of this method. In the following introduction process, this method is applied to Figure 1 the network architecture shown.

[0314] For the convenience of introduction, in the following, this method is taken as an example of being executed by the network device and the terminal device. Because this embodiment takes the application in Figure 1 the network architecture shown as an example, therefore, the network device described below can be the network device in Figure 1 the network architecture shown, and the terminal device described below can be the terminal device in Figure 1 the network architecture shown.

[0315] S71. The terminal device determines that the measurement values obtained by continuously measuring on the non-anchor carrier of the serving cell of the terminal device for K times are all unavailable. K is, for example, an integer greater than or equal to 1.

[0316] In the embodiments of the present application, the serving cell of the terminal device is configured with an anchor carrier and one or more non-anchor carriers.

[0317] These K measurement processes can be pairwise adjacent measurement processes, that is, the terminal device has performed a total of K measurement processes during this period, and all K measurement processes are measurement processes performed on non-anchor carriers; or, these K measurement processes may not be pairwise adjacent measurement processes. For example, the i-th measurement process and the (i + 1)-th measurement process among the K measurement processes are non-adjacent measurement processes. This can be understood as the terminal device has performed a total of K + P measurement processes during this period, where K measurement processes are measurement processes performed on non-anchor carriers, and P measurement processes are measurement processes performed on the anchor carrier, and the measurement processes on the anchor carrier and the measurement processes on the non-anchor carrier may be interleaved. For example, the j-th measurement process among the K + P measurement processes is a measurement process on the anchor carrier, and the (j + 1)-th measurement process is a measurement process on the non-anchor carrier. If this is the case, then for two consecutive measurement processes on non-anchor carriers, even if there is an intervening measurement process on the anchor carrier in between, the two consecutive measurement processes on non-anchor carriers are considered continuous because they are both measurement processes performed on non-anchor carriers. K can be configured by the network device, or pre-configured in the terminal device, or can also be specified by the protocol.

[0318] S72. The terminal device performs measurements only on the anchor carrier of the serving cell of the terminal device within the first time period.

[0319] If the measurement values obtained from continuously performing K measurements on non-anchor carriers are all unavailable, it indicates that the measurement results of the non-anchor carrier have a large deviation from the measurement results of the anchor carrier within a period of time. In this case, the terminal device can continue to perform measurements only on the anchor carrier for a period of time, or the terminal device does not perform measurements on the non-anchor carrier of the serving cell within the first time period, so as to reduce the error caused by continuing to perform measurements on non-anchor carriers.

[0320] The first time period can be configured by the network device, or the first time period can be pre-configured in the terminal device, or the first time period can also be specified by the protocol. Among them, the first time period can be an absolute time length, such as 100 seconds, etc.; or, the first time period can also be a relative time length, such as the unit of the first time period is a DRX cycle, or it can also be other units. For example, the first time period specified by the protocol is the length of 3 DRX cycles, which means that if the measurement values obtained from continuously performing K measurements on non-anchor carriers are all unavailable, then within the next 3 DRX cycles, the terminal device performs measurements only on the anchor carrier.

[0321] When configuring the first duration, it can be configured as time information. For example, the network device sends the information of the first duration to the terminal device, or the first duration information is pre-configured in the terminal device, or the protocol stipulates the first duration information, etc. Then, if the measurement values obtained from continuous K measurements on the non-anchor carrier are all unavailable, the terminal device starts timing until the first duration arrives. Before the first duration arrives, the terminal device only measures on the anchor carrier. For example, the terminal device can use the method of self-starting a timer to time the first duration, or can use the method of self-starting a chronometer to time the first duration, or can also use other methods to time the first duration. After the first duration arrives, the terminal device can measure on the anchor carrier or on the non-anchor carrier. For example, if the first duration is an absolute time length, the terminal device only needs to time the first duration; for another example, if the first duration is a relative time length, for example, the unit of the first duration is the DRX cycle, then the duration that the terminal device needs to time is i×T, where T represents the length of the DRX cycle and i represents the number of DRX cycles corresponding to the first duration. For example, if the first duration is 3 DRX cycles, then the duration that the terminal device needs to time is 3T.

[0322] Alternatively, when configuring the first duration, it can also be configured as a timer. For example, the network device sends the information of the first timer to the terminal device, and the network device indicates that the timing duration of the first timer is the first duration; or, the first timer information is pre-configured in the terminal device, and the timing duration of the first timer is the first duration; or, the protocol stipulates the first timer. For example, the protocol stipulates that if the measurement values obtained from continuous K measurements on the non-anchor carrier of the serving cell of the terminal device are all unavailable, start the first timer, and the timing duration of the first timer is the first duration. Then, if the measurement values obtained from continuous K measurements on the non-anchor carrier are all unavailable, the terminal device can start the first timer, and the timing duration of the first timer is the first duration. Before the first timer times out, the terminal device only measures on the anchor carrier. After the first timer times out, the terminal device can measure on the anchor carrier or on the non-anchor carrier. For example, if the first duration is an absolute time length, the timing duration of the first timer can be the first duration; for another example, if the first duration is a relative time length, for example, the unit of the first duration is the DRX cycle, then the timing duration of the first timer can be i×T, where T represents the length of the DRX cycle and i represents the number of DRX cycles corresponding to the first duration. For example, if the first duration is 3 DRX cycles, then the timing duration of the first timer can be 3T. In addition, the first timer can also have other names, such as it can be called a prohibited timer, a prohibited measurement timer, or a temporary prohibited measurement timer, etc. The name does not constitute a limitation on the feature itself.

[0323] For example, refer to Figure 4, the terminal device measures NRSRP1 on the anchor carrier. After that, if the terminal device determines that the non-anchor carrier measurement condition is met, the terminal device measures NRSRP2 on the non-anchor carrier. For example, if the difference between the converted value corresponding to NRSRP2 and NRSRP1 is greater than the first threshold, the terminal device continues to measure on the anchor carrier and obtains NRSRP3. For example, if the difference between the converted value corresponding to NRSRP2 and NRSRP3 is also greater than the first threshold, the terminal device determines that NRSRP2 is unavailable. Then, for example, the terminal device measures NRSR4 on the non-anchor carrier again. In a similar manner, the terminal device determines that NRSRP4 is unavailable based on NRSRP3 and NRSRP5 obtained by measuring on the anchor carrier. For example, if K = 2, then the measurement values obtained by measuring on the non-anchor carrier twice in a row are both unavailable. Then, within the first time period, the terminal device only measures on the anchor carrier. For example Figure 4 The first time period is denoted as T. Within the T time period, the terminal device only measures on the anchor carrier and obtains (x - 5) NRSRPs such as NRSRP6 to NRSRP x.

[0324] Figure 7 The introduction of the first time period in the embodiments shown can also be applied to Figure 2 the embodiments shown or Figure 6 the embodiments shown.

[0325] Optionally, after the first time period, the terminal device can continue to measure on the anchor carrier, or if the non-anchor carrier measurement condition is still met, the terminal device can also measure on the non-anchor carrier. This makes the measurement of the terminal device more flexible, avoiding errors caused by inter-carrier frequency selectivity while maximizing the flexibility of the terminal device in inter-carrier measurement selection and reducing unnecessary power consumption.

[0326] S73: The terminal device measures on the anchor carrier of the serving cell of the terminal device to obtain a second measurement value. Among them, S73 to S78 introduced later can be included in S71, that is, S73 to S78 are used to introduce how to determine whether the measurement result (or measurement value) of the non-anchor carrier is available.

[0327] For more content about S73, reference can be made to Figure 2 the introduction of S21 in the embodiments shown.

[0328] S74: The terminal device measures on the non-anchor carrier of the serving cell of the terminal device to obtain a first measurement value.

[0329] If the terminal device determines that the non-anchor carrier measurement condition is satisfied, it can measure on the non-anchor carrier, or it can also measure on the anchor carrier. The non-anchor carrier can be one of one or more non-anchor carriers of the serving cell of the terminal device. For example, the terminal device selects to measure on the non-anchor carrier and obtains a first measurement value.

[0330] For more content about S74, reference can be made to Figure 2 the description of the embodiment shown for S22.

[0331] S75. The terminal device obtains a first conversion value according to the first measurement value and the first difference.

[0332] The first difference can indicate the power difference between the non-anchor carrier and the anchor carrier, or rather, the first difference is the power difference between the non-anchor carrier and the anchor carrier. This power difference can come from the network device. For example, before S64, the network device sends the first difference to the terminal device, and the terminal device receives the first difference from the network device. This power difference can be obtained by the network device based on the transmission power of the signal sent to the anchor carrier and the transmission power of the signal sent to the non-anchor carrier. That is, the transmission power of the signal sent by the network device to the anchor carrier and the transmission power of the signal sent by the network device to the non-anchor carrier are both known to the network device, and the difference between these two transmission powers can be used as the first difference.

[0333] For example, the terminal device can add the first measurement value and the first difference, and the sum value obtained is the first conversion value; or, the terminal device can subtract the first difference from the first measurement value, and the difference obtained is the first conversion value. Among them, if the terminal device takes the difference obtained by subtracting the first difference from the first measurement value as the first conversion value, then the first conversion value can take the actual value of the first measurement value minus the first difference, or take the actual value of the first difference minus the first measurement value, or take the absolute value of the difference between the first measurement value and the first difference.

[0334] For more content about S75, reference can be made to Figure 2 the description of the embodiment shown for S23.

[0335] S76. The terminal device determines whether the difference (or the absolute value of the difference) between the first conversion value and the second measurement value is greater than the first threshold.

[0336] If the terminal device determines that the difference between the first conversion value and the second measurement value is less than or equal to the first threshold, the terminal device may determine that the first conversion value is available, or equivalently, determine that the first measurement value is available. Then the process can end. For example, the terminal device can utilize the first conversion value, such as performing filtering based on the first conversion value. If the terminal device determines that the difference between the first conversion value and the second measurement value is greater than the first threshold, then S66 can be continued.

[0337] For more content about S76, reference can be made to Figure 2 the description of the embodiment shown for S24.

[0338] S77: The terminal device performs measurements on the anchor carrier to obtain a third measurement value.

[0339] In the embodiments of the present application, if the terminal device determines that the difference between the first conversion value and the second measurement value is greater than the first threshold, then when the next DRX cycle that needs to be measured arrives, the terminal device can perform measurements on the anchor carrier.

[0340] For more content about S77, reference can be made to Figure 2 the description of the embodiment shown for S25.

[0341] S78: The terminal device determines whether the first measurement value is available based on the third measurement value. Or equivalently, the terminal device determines whether the first conversion value is available based on the third measurement value.

[0342] After obtaining the third measurement value, the terminal device can determine whether the first measurement value is available based on the third measurement value. For example, the terminal device calculates the difference between the first conversion value and the third measurement value. If this difference (or the absolute value of this difference) is less than or equal to the first threshold, then although the difference between the first conversion value and the second measurement value is greater than the first threshold, since the difference between the first conversion value and the third measurement value is less than or equal to the first threshold, the terminal device can determine that the first conversion value is available, or equivalently, determine that the first measurement value is available. If the difference between the first conversion value and the third measurement value is greater than the first threshold, then the terminal device can determine that the first conversion value is not available, or equivalently, determine that the first measurement value is not available.

[0343] For more content about S78, reference can be made to Figure 2 the description of the embodiment shown for S26. Among them, S73 to S78 are all optional steps and not necessarily executed, which are represented by dashed lines in Figure 7 it.

[0344] As an alternative implementation, a behavior of the terminal device can be clarified, that is, when the terminal device performs measurements on a non-anchor carrier, how to ensure that the measurement results of the anchor carrier are reliable. For example, when determining whether the measurement results of the non-anchor carrier are available, the measurement results of the anchor carrier are used. If the time interval between the acquisition time of the measurement results of the anchor carrier and the acquisition time of the measurement results of the non-anchor carrier is relatively long, the measurement results of the anchor carrier may not be accurate enough, and using the measurement results of the anchor carrier to determine whether the measurement results of the non-anchor carrier are available will also result in inaccurate determination results. Therefore, the embodiments of the present application propose that the terminal device can perform measurements on the anchor carrier regularly, so as to determine whether the measurement results of the non-anchor carrier are available based on the recent measurement results of the anchor carrier as much as possible, and improve the accuracy of the determination results.

[0345] For example, the terminal device can perform a measurement every M DRX cycles. The measurement can be performed on the anchor carrier or on the non-anchor carrier. M can be an integer greater than or equal to 1. M can be configured by the network device, pre-configured in the terminal device, or specified by the protocol. For example, if M = 1, the terminal device needs to perform a measurement in each DRX cycle. For example, continuing to refer to Figure 3 , when the terminal device obtains NRSRP1, it has performed a measurement. When it obtains NRSRP2, it has performed the next measurement. These two measurement processes are adjacent. When it obtains NRSRP3, it has performed another measurement. These three measurement processes are adjacent to each other in pairs. If M = 1, the terminal device measures and obtains NRSRP1 within the first DRX cycle, measures and obtains NRSRP2 within the next DRX cycle (or the second DRX cycle), and measures and obtains NRSRP3 within the next DRX cycle (or the third DRX cycle). If M > 1, taking M = 2 as an example, the terminal device measures once every two DRX cycles. For example, the terminal device measures and obtains NRSRP1 within the first DRX cycle, measures and obtains NRSRP2 within the third DRX cycle, and measures and obtains NRSRP3 within the fifth DRX cycle.

[0346] Then, the embodiments of this application stipulate that in every M×N DRX cycles, the terminal device can perform at least one measurement on the anchor carrier. N can be configured by the network device, or pre-configured in the terminal device, or can also be stipulated by the protocol. This can also be understood as that in every N consecutive measurement processes, at least one measurement process performed on the anchor carrier can be included. For example, when M = 1, in every N DRX cycles, the terminal device can perform at least one measurement on the anchor carrier, or in other words, in every N consecutive measurement processes, at least one measurement process performed on the anchor carrier can be included. Another example, when M = 2, in every 2N DRX cycles, the terminal device can perform at least one measurement on the anchor carrier, or in other words, in every 2N consecutive measurement processes, at least one measurement process performed on the anchor carrier can be included.

[0347] For example, referring to Figure 5 , taking M = 1 and N = 4 as an example. That is to say, the terminal device will perform measurements in each DRX cycle, and in every 4 DRX cycles, the terminal device can perform at least one measurement on the anchor carrier, and Figure 5 taking the example that in every 4 DRX cycles, the terminal device can perform one measurement on the anchor carrier. Figure 5 In, in the first DRX cycle, the terminal device performs a measurement on the anchor carrier and obtains NRSRP1; in the second DRX cycle, the terminal device performs a measurement on the non-anchor carrier and obtains NRSRP2; in the third DRX cycle, the terminal device performs a measurement on the non-anchor carrier and obtains NRSRP3; in the fourth DRX cycle, the terminal device performs a measurement on the non-anchor carrier and obtains NRSRP4; in the fifth DRX cycle, the terminal device returns to the non-anchor carrier to perform a measurement and obtains NRSRP5; in the sixth DRX cycle, the terminal device performs a measurement on the non-anchor carrier and obtains NRSRP6; in the seventh DRX cycle, the terminal device performs a measurement on the non-anchor carrier and obtains NRSRP7; in the eighth DRX cycle, the terminal device performs a measurement on the non-anchor carrier and obtains NRSRP8, and so on.

[0348] In the embodiments of this application, if the measurement values obtained from continuously performing K measurements on the non-anchor carrier are all unavailable, it indicates that the measurement results of the non-anchor carrier have a large deviation from the measurement results of the anchor carrier within a period of time. In this case, the terminal device can continuously perform measurements only on the anchor carrier for a period of time, so as to reduce the error caused by continuing to perform measurements on the non-anchor carrier.

[0349] Moreover, the terminal device can compare the first measurement value obtained on the non-anchor carrier with the second measurement value obtained on the anchor carrier. If the difference is large (i.e., greater than the first threshold), the terminal device can also perform a measurement on the anchor carrier to obtain a third measurement value, and then compare the first measurement value with the third measurement value to determine whether the first measurement value is available. Instead of simply using the measurement result of the anchor carrier once to determine whether the result of the non-anchor carrier is available, multiple measurement results of the anchor carrier can be used to determine whether the measurement result of the non-anchor carrier is available, so as to consider the change of the channel condition as much as possible, reduce the error caused by one comparison, and improve the accuracy of the judgment result.

[0350] In addition, the terminal device can regularly perform measurements on the anchor carrier, so as to determine whether the measurement result of the non-anchor carrier is available according to the measurement result of the anchor carrier recently, avoid too long an interval between the acquisition time of the measurement result of the non-anchor carrier and the acquisition time of the measurement result of the anchor carrier, and improve the accuracy of the determination result.

[0351] Among them, as above Figure 2 The solution provided by the embodiment shown, Figure 6 The solution provided by the embodiment shown, and Figure 7 The solution provided by the embodiment shown, these three solutions can be applied independently respectively, or can also be applied in any combination. For example, Figure 2 The solution provided by the embodiment shown and Figure 6 The solution provided by the embodiment shown can be combined and applied; or, Figure 2 The solution provided by the embodiment shown and Figure 7 The solution provided by the embodiment shown can be combined and applied; or, Figure 6 The solution provided by the embodiment shown and Figure 7 The solution provided by the embodiment shown can be combined and applied; or, Figure 2 The solution provided by the embodiment shown, Figure 6 The solution provided by the embodiment shown, and Figure 7 The solution provided by the embodiment shown can be combined and applied.

[0352] Next, the embodiment of the present application provides a fourth communication method, which is used to introduce a simpler way to determine whether the measurement result of the non-anchor carrier is available. Please refer to Figure 8 , which is the flowchart of this method. In the following introduction process, this method is applied to Figure 1 The network architecture shown is taken as an example.

[0353] For the convenience of introduction, in the following, this method is taken as an example of being executed by the network device and the terminal device. Because this embodiment is applied to Figure 1Taking the network architecture shown as an example, therefore, the network device described hereinafter may be Figure 1 the network device in the network architecture shown. The terminal device described hereinafter may be Figure 1 the terminal device in the network architecture shown.

[0354] S81. The network device determines indication information, and the indication information can indicate whether the measurement result of the non-anchor carrier of the serving cell of the terminal device is available.

[0355] For example, if the network device determines that the frequency difference between the non-anchor carrier and the anchor carrier of the serving cell is relatively small, or in other words, these two carriers are relatively close, then the network device believes that the channel fading and other characteristics of these two carriers are similar, so it can be considered that the measurement result of the non-anchor carrier is available. Then the network device can determine the indication information, and the indication information indicates that the measurement result of the non-anchor carrier of the serving cell of the terminal device is available.

[0356] Or, if the network device determines that the frequency difference between the non-anchor carrier and the anchor carrier of the serving cell is relatively large, or in other words, these two carriers are far apart, then the network device believes that the channel fading and other characteristics of these two carriers may be quite different, so it can be considered that the measurement result of the non-anchor carrier is unavailable. Then the network device can determine the indication information, and the indication information indicates that the measurement result of the non-anchor carrier of the serving cell of the terminal device is unavailable.

[0357] S82. The network device sends the indication information to the terminal device, and the terminal device receives the indication information from the network device.

[0358] After the network device determines the indication information, it can send the indication information to the terminal device. For example, the indication information can be carried in the first message and sent to the terminal device. The first message is, for example, a high-layer signaling, and the high-layer signaling is, for example, a radio resource control (RRC) signaling or a media access control (MAC) control element (CE), etc.; or, the first message can also be a physical layer signaling, and the physical layer signaling is, for example, a downlink control information (DCI), etc.; or, the first message can also be a system message, and the system message is, for example, a system information block (SIB), for example, the SIB is used to configure the non-anchor carrier for the terminal device, for example, it is SIB22.

[0359] S83. The terminal device determines whether the measurement result of the terminal device on the non-anchor carrier is available according to the indication information.

[0360] After the terminal device receives the indication information, if the indication information indicates that the measurement result of the non-anchor carrier of the serving cell is available, the terminal device may determine that the measurement result of the non-anchor carrier of the serving cell is available; or, if the indication information indicates that the measurement result of the non-anchor carrier of the serving cell is not available, the terminal device may determine that the measurement result of the non-anchor carrier of the serving cell is not available.

[0361] If the indication information indicates that the measurement result of the non-anchor carrier of the serving cell is not available, then the terminal device may perform measurements only on the anchor carrier. For example, the terminal device may always perform measurements only on the anchor carrier. Even if the non-anchor carrier measurement conditions are met, the terminal device still performs measurements only on the anchor carrier. Regarding the non-anchor carrier measurement conditions, reference may be made to Figure 2 the description of the embodiments shown. Or, the terminal device may perform measurements on the anchor carrier within a second time period. During the second time period, even if the non-anchor carrier measurement conditions are met, the terminal device still performs measurements only on the anchor carrier. After the second time period, the terminal device may continue to perform measurements on the anchor carrier, or, if the non-anchor carrier measurement conditions are met, the terminal device may also perform measurements on the non-anchor carrier. The second time period may be configured by the network device. For example, in addition to the indication information, the first message may also include information about the second time period, or the network device may also indicate the second time period to the terminal device through other messages other than the first message; or, the second time period may be pre-configured in the terminal device; or, the second time period may also be specified by the protocol.

[0362] If the indication information indicates that the measurement result of the non-anchor carrier of the serving cell is available, then next the terminal device may perform measurements on the anchor carrier or on the non-anchor carrier. That is, even if the indication information indicates that the measurement result of the non-anchor carrier of the serving cell is available, the terminal device does not necessarily perform measurements on the non-anchor carrier. Whether the terminal device performs measurements on the anchor carrier or on the non-anchor carrier depends on the implementation of the terminal device, and the embodiments of the present application do not make any restrictions. Here, it is only stated that if the indication information indicates that the measurement result of the non-anchor carrier of the serving cell is available, then when the non-anchor carrier measurement conditions are met, the terminal device may choose to perform measurements on the non-anchor carrier. If the terminal device performs measurements on the non-anchor carrier, for example, obtains a first measurement value, then the terminal device may obtain a first conversion value based on the first difference and the first measurement value. Regarding the manner in which the terminal device obtains the first conversion value, reference may be made to Figure 2Introduction of the illustrated embodiment. The terminal device will consider the first conversion value as available, or rather, the terminal device considers the first measurement value as available. Therefore, after obtaining the first conversion value, the terminal device can utilize the first conversion value without having to determine whether the first measurement value is available based on the measurement result of the anchor carrier. The terminal device utilizes the first conversion value. For example, it can perform filtering based on the first conversion value, or start neighbor cell measurement based on the first conversion value, or determine to relax the measurement condition based on the first conversion value. Regarding the concept of the availability of the first measurement value, reference can be made to Figure 2 Introduction of the illustrated embodiment.

[0363] In addition, there may also be a situation where the network device may not send the indication information, or although the network device sends the indication information, the terminal device does not receive it. If either of these two situations occurs, then the terminal device can perform measurements only on the anchor carrier to avoid the errors brought by the measurement results of non-anchor carriers to a certain extent. Or, the terminal device can also adopt Figure 2 the illustrated embodiment, Figure 6 the illustrated embodiment or Figure 7 the method introduced in the illustrated embodiment shown to perform measurements.

[0364] In the embodiments of the present application, by indicating whether the measurement result of the non-anchor carrier is available through the network device, problems such as errors and additional power consumption brought by the measurement results of non-anchor carriers caused by the imperfect judgment mechanism of the terminal device can be reduced. For example, if the network device indicates that the measurement result of the non-anchor carrier is not available, the terminal device can avoid measuring on the non-anchor carrier, which can avoid the errors brought by the measurement results of non-anchor carriers to a certain extent; and if the network device indicates that the measurement result of the non-anchor carrier is available, when the terminal device obtains the measurement result of the non-anchor carrier, it does not need to determine whether the measurement result of the non-anchor carrier is available anymore, but can directly utilize it, reducing the burden on the terminal device.

[0365] The following describes the apparatus used to implement the above method in the embodiments of the present application with reference to the accompanying drawings. Therefore, the content in the above text can be used in subsequent embodiments, and the repeated content will not be elaborated.

[0450] An embodiment of this application further provides a communication device, which may be a terminal device or a circuit. The communication device may be used to perform the actions performed by the terminal device in the foregoing method embodiments.

[0451] When the communication device is a terminal device, Figure 14 a simplified schematic structural diagram of a terminal device is shown. For ease of understanding and convenient illustration, Figure 14 in the figure, a mobile phone is taken as an example of the terminal device. As Figure 14 shown, the terminal device includes a processor, a memory, a radio frequency circuit, an antenna, and an input / output device. The processor is mainly configured to process communication protocols and communication data, control the terminal device, execute software programs, process data of software programs, etc. The memory is mainly configured to store software programs and data. The radio frequency circuit is mainly configured to convert baseband signals into radio frequency signals and process radio frequency signals. The antenna is mainly configured to transmit and receive radio frequency signals in the form of electromagnetic waves. The input / output device, such as a touch screen, a display screen, a keyboard, etc., is mainly configured to receive data input by a user and output data to the user. It should be noted that some types of terminal devices may not have an input / output device.

[0452] When data needs to be sent, after the processor performs baseband processing on the data to be sent, it outputs a baseband signal to the radio frequency circuit. The radio frequency circuit performs radio frequency processing on the baseband signal and then transmits the radio frequency signal outward in the form of electromagnetic waves through the antenna. When data is sent to the terminal device, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor. The processor converts the baseband signal into data and processes the data. For ease of explanation, Figure 14Only one memory and one processor are shown. In an actual terminal device product, there may be one or more processors and one or more memories.
