Background technique

At present, before configuring the dual connectivity (DC) network architecture, that is, before adding secondary base stations to the DC, the primary base station in the DC can be configured with a system frame number and frame timing difference (system frame number and frame timing difference). , SFTD) The terminal equipment with measurement capability measures the cells that may become secondary base stations to obtain the time difference between these cells and the serving cell of the terminal equipment. The terminal device sends the measured time difference to the main base station, so that when the main base station configures the gap for the terminal device or other terminal devices in the serving cell, it can try to make the configured gap cover the synchronization signal sent by other cells to ensure the terminal The device can detect synchronization signals from other cells in the gap to complete the measurement of other cells. Among them, when a terminal device with SFTD capability performs measurement on other cells, it does not need a gap, but can directly perform measurement.

But after the DC architecture configuration is completed, if the primary base station needs to configure terminal equipment to measure the cell of the secondary base station, for example, under the E-UTRA NR dual connectivity (EN-DC) architecture If a long term evolution (LTE) base station needs to configure terminal equipment to measure the cell of a new radio (NR) base station, it will configure a gap for the terminal equipment, and the terminal equipment will perform measurement in the gap. In the time period corresponding to the gap, the terminal device cannot communicate with the serving cell of the terminal device, that is, the gap configured by the main base station actually occupies the transmission time between the terminal device and the serving cell of the terminal device. However, according to the previous introduction, for a terminal device with SFTD capability, when measuring other cells, the measurement can be completed without a gap. Then the base station configures gaps for such terminal devices, which causes a waste of transmission resources.

The various terminal devices described above, if they are located on the vehicle (for example, placed in the vehicle or installed in the vehicle), can be regarded as vehicle-mounted terminal equipment, for example, the vehicle-mounted terminal equipment is also called on-board unit (OBU). ).

In the embodiment of the present application, the terminal device may also include a relay. Or it can be understood that everything that can communicate with the base station can be regarded as a terminal device.

2) Network equipment, for example, including access network (AN) equipment, such as a base station (e.g., access point), which can refer to equipment that communicates with wireless terminal equipment through one or more cells on the air interface in the access network Or, for example, a network device in a vehicle-to-everything (V2X) technology is a road side unit (RSU). The base station can be used to convert received air frames and IP packets into each other, and act as a router between the terminal device and the rest of the access network, where the rest of the access network can include the IP network. The RSU can be a fixed infrastructure entity that supports V2X applications, and can exchange messages with other entities that support V2X applications. The network equipment can also coordinate the attribute management of the air interface. For example, the network equipment may include a long term evolution (LTE) system or an evolved base station (NodeB or eNB or e-NodeB, evolutional Node B) in a long term evolution-advanced (LTE-A) system, or may comprise a fifth generation mobile communication technology ^(the 5 ^th generation, 5G) a new air interface (new radio, NR) system (also referred to as NR system) Next Generation node B (next generation node B, gNB ) or else It may include a centralized unit (CU) and a distributed unit (DU) in a cloud radio access network (Cloud RAN) system, which is not limited in the embodiment of the present application.

For terminal equipment, etc., there are no specific restrictions.

3) Multi-RAT dual connectivity (MR-DC). In the LTE system, the terminal device supports simultaneous access to two network devices. This access method is called dual connectivity (dual connectivity). , DC), one of the network devices is the main network device, and the other network device is the auxiliary network device. In the development and evolution of wireless communication systems, operators will deploy 5G NR systems and LTE systems at the same time, and terminal equipment also supports simultaneous access to LTE network equipment and NR network equipment, because LTE is also called the evolved universal land surface Wireless access (evolved universal terrestrial radio access, E-UTRA), so this access method is called E-UTRA NR dual connectivity (EN-DC). In the EN-DC mode, the LTE network equipment is the main network equipment, and the NR network equipment is the auxiliary network equipment. Of course, as the system evolves, in the future it can also support the new air interface and the evolved universal land surface wireless access dual connectivity (NR E-UTRA dual connectivity, NE-DC), that is, NR network equipment is the main network equipment, LTE network The equipment is the auxiliary network equipment. Since both EN-DC and NE-DC terminal devices are connected to network devices of two different wireless access technologies, these DC modes can also be collectively referred to as MR-DC.

4) The terms "system" and "network" in the embodiments of this 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 the associated objects, indicating that there can be three relationships, for example, A and/or B, which can mean: A alone exists, A and B exist at the same time, and B exists alone, where A, B can be singular or plural. The character "/" generally indicates that the associated objects before and after are in an "or" relationship. "The following at least one item (a)" or similar expressions refers to any combination of these items, including any combination of a single item (a) or a plurality of items (a).

Importance, etc. For example, the first frequency and the second frequency are only used to distinguish different data packets, but do not indicate the difference in size, priority, or importance of the two frequencies.

The foregoing introduces some terms and concepts involved in the embodiments of the present application, and the technical features involved in the embodiments of the present application are introduced below.

In the LTE system, when deploying networks between base stations, it may not be possible to align time. After configuring the DC architecture for the LTE base station, the LTE primary base station will configure a gap for the terminal device, and the terminal device will measure the synchronization signal from the LTE secondary base station in the gap. However, the time of the LTE primary base station and the LTE secondary base station may not be aligned, causing the gap configured by the LTE primary base station to be misaligned with the time of the LTE secondary base station. This may cause the gap configured by the LTE primary base station to not fully cover or to cover the time from the LTE secondary base station. Synchronization signal, which may cause the measurement result obtained by the terminal device to be inaccurate, or may cause the terminal device to fail to complete the measurement. To this end, the system frame number and subframe timing difference (SFN and subframe timing difference, SSTD) measurement is introduced. Terminal devices with SSTD measurement capabilities can measure the cell of the LTE secondary base station without configuring gaps, and obtain The time difference between the cell of the LTE secondary base station and the cell of the LTE primary base station. The terminal device sends the time difference to the LTE master base station, so that the LTE master base station can configure the gap for the terminal device according to the time difference.

In the NR system, due to the network deployment of the EN-DC architecture, the LTE primary base station and the NR secondary base station also have the problem of time alignment. Since the terminal equipment relies on the synchronization/physical broadcast channel block (SSB) periodically broadcast by the NR secondary base station to measure the secondary base station, currently, the LTE primary base station needs to configure the gap for the terminal equipment to allow the terminal equipment to be Receive the SSB from the secondary base station within the gap. However, because the time of the LTE primary base station and the NR secondary base station cannot be aligned, the gap configured by the LTE primary base station may not include the SSB of the NR secondary base station. As a result, the terminal device cannot receive the SSB from the NR secondary base station in the gap, thus failing to complete the measurement. . For example, referring to Figure 1, the measurement period of the different system (for example, for the LTE system, the NR system is the different system) is, for example, 40ms, where the gap is 6ms, but the SSB from the cell of the NR secondary base station falls in the remaining Therefore, the gap cannot cover the SSB of the cell of the NR secondary base station, and the terminal device cannot complete the measurement.

At present, in order to solve the problem that the primary base station does not know the time difference between the added secondary base station and the primary base station, SFTD measurement is introduced. The difference from the SSTD measurement is that the base station can be configured with terminal equipment with SFTD measurement capability. When adding, it measures the time difference between the primary base station and possible secondary base stations, and then reports the measured time difference to the primary base station to assist the primary base station in configuring gaps for the terminal device or other terminal devices in the cell. Time difference, try to make the configured gap cover the SSB of the secondary base station, and ensure that the terminal device can detect the SSB from the secondary base station in the gap.

It can be seen that a terminal device with SFTD measurement capability does not need a gap when measuring other cells, but can directly perform measurement.

However, after the DC architecture configuration is completed, if the primary base station needs to configure the terminal equipment to measure the cell of the secondary base station, for example, in the EN-DC architecture, the LTE base station needs to configure the terminal equipment to measure the cell of the NR base station, then the terminal equipment will still be configured with gap. The terminal device performs measurement in the gap. In the time period corresponding to the gap, the terminal device cannot communicate with the serving cell of the terminal device, that is, the gap configured by the main base station actually occupies the transmission time between the terminal device and the serving cell of the terminal device. However, according to the previous introduction, for a terminal device with SFTD capability, when measuring other cells, the measurement can be completed without a gap. Then the base station configures gaps for such terminal devices, which causes a waste of transmission resources.

In view of this, the technical solutions of the embodiments of the present application are provided. In the embodiment of the present application, if the terminal device has the first measurement capability, it can inform the network device, and the network device can configure the terminal device to be within the capability of the terminal device and complete the measurement of other cells without gaps. In this way, it is not necessary to configure gaps for terminal devices with allowable capabilities, so that the measurement process can be completed, transmission resources can be efficiently used, and the uplink and downlink throughput of terminal devices with this capability can be improved.

The technical solutions provided by the embodiments of this application can be applied to the 4th generation (4G) mobile communication technology (the 4th generation, 4G) system, such as the LTE system, or can be applied to the 5G system, such as the NR system, or can also be applied to the next generation mobile communication System and other similar mobile communication systems. In addition, the technical solutions provided by the embodiments of the present application can also be applied to device-to-device (device-to-device, D2D) scenarios, which can be NR D2D scenarios, LTE D2D scenarios, etc., or can be applied to V2X scenarios, which can be The NR V2X scenario may also be an LTE V2X scenario, etc., or may also be applied to other scenarios or other communication systems.

The following describes the network architecture applied by the embodiments of the present application.

Please refer to FIG. 2A, which is a network architecture applied in the embodiment of this application.

Figure 2A includes two network devices and terminal devices. There is a dual-connection architecture between the two network devices. The network device 1 is, for example, the main network device, and the network device 2A is, for example, the auxiliary network device. The terminal device can communicate with these two network devices. Of course, the number of terminal devices in FIG. 2A is just an example. In practical applications, a network device can provide services for multiple terminal devices.

The network device in FIG. 2A is, for example, an access network device, such as a base station. Among them, the access network equipment corresponds to different equipment in different systems. For example, it can correspond to the eNB in the 4G system, and the 5G system corresponds to the access network equipment in 5G, such as gNB, or it is the access network equipment in the subsequent evolved communication system. Network access equipment. For example, if Figure 2A is an EN-DC architecture, network device 1 is an LTE network device, and network device 2 is an NR network device; or, Figure 2A is an NE-DC architecture, then network device 1 is an NR network device, and network device 2 is LTE network equipment, etc.

Network access equipment. Figure 2B can be understood as a dual connection architecture has not yet been formed.

Next, the technical solutions provided by the embodiments of the present application will be introduced with reference to the accompanying drawings.

When the terminal device is just turned on, it will report the capabilities of the terminal device to the network device, or when the terminal device switches to a new cell, the network device will request the terminal device to report the capabilities of the terminal device. When a user is going to do business through a terminal device, for example, when the user wants to use a terminal device to surf the Internet, the network device that provides services for the terminal device (considered as the main network device at this time) may wish to add auxiliary network devices to the terminal device to form a DC Architecture to increase throughput and increase network speed. Under the DC architecture, the main network equipment will configure the terminal equipment to measure other cells in the gap, and the gap will occupy the transmission time between the terminal equipment and the serving cell of the terminal equipment. In this scenario, the solution provided in the embodiment of the present application can be used. For capable terminal devices, the main network device may not need to configure gaps, which reduces the waste of transmission resources and improves the throughput of the terminal device.

The embodiment of the present application provides a first communication method. Please refer to FIG. 3, which is a flowchart of this method. In the following introduction process, the application of this method to the network architecture shown in FIG. 2A or FIG. 2B is taken as an example. In addition, the method can be executed by two communication devices, for example, the first communication device and the second communication device. Among them, the first communication device or the second communication device may be a network device or a communication device capable of supporting the network device to implement the functions required by the method, or may be a terminal device or a terminal device capable of supporting the functions required by the terminal device to implement the method. The communication device may of course also be other communication devices, such as a chip system. And there are no restrictions on the implementation of the first communication device or the second communication device. For example, the two communication devices can be implemented in the same form, for example, both can be implemented in the form of equipment, or the two communication devices can also be implemented as Different forms, for example, the first communication device is implemented in the form of a device, the second communication device is implemented in the form of a chip system, and so on. Among them, the network device is, for example, a base station.

For ease of introduction, in the following, the execution of the method by the terminal device and the network device is taken as an example, that is, the first communication device is a terminal device and the second communication device is a network device as an example. If the embodiments of this application are applied to the network architecture shown in FIG. 2A, the terminal device described below can realize the functions of the terminal device in the network architecture shown in FIG. 2A, and the network device described below can realize the function of the terminal device in the network architecture shown in FIG. 2A. The function of the network device 1 in the network architecture shown in 2A. Or, if the embodiments of the present application are applied to the network architecture shown in FIG. 2B, the terminal device described below can realize the functions of the terminal device in the network architecture shown in FIG. 2B, and the network device described below may The function of the network device in the network architecture shown in FIG. 2B is realized.

S31. The terminal device sends first indication information to the network device, where the first indication information is used to indicate that the terminal device has the first measurement capability, and the network device can determine that the terminal device has the first measurement capability after receiving the first indication information from the terminal device. .

The first measurement capability indicates that the terminal device can measure other frequencies included in each frequency combination on one frequency included in each frequency combination in at least one frequency combination without configuring the measurement interval, at least one frequency The combination includes all frequency combinations supported by the terminal device.

The terminal device may support at least one frequency combination, and the number of at least one frequency combination may be greater than or equal to one. The at least one frequency combination may include a combination of a frequency combination under the first wireless access technology and a frequency combination under the second wireless access technology supported by the terminal device. Or, in order to distinguish the concept of frequency combination, it can also be expressed as that at least one frequency combination may include the sub-frequency combination under the first wireless access technology and the sub-frequency combination under the second wireless access technology supported by the terminal device The combination. The frequency combination mentioned here is used to express the frequency combination supported by the terminal device when the first wireless technology and the second wireless technology work at the same time. The sub-frequency combination is used to express the frequency combination supported by the terminal device when operating under the first wireless access technology, or to express the frequency combination supported by the terminal device when operating under the second wireless access technology. For example, if the terminal device supports sub-frequency combination 1 under the first wireless access technology, and supports sub-frequency combination 2 under the second wireless access technology, one frequency combination included in at least one frequency combination may be sub-frequency combination 1 and sub-frequency combination 1 and sub-frequency combination. The combination between frequency combination 2.

Wherein, the sub-frequency combination of the first wireless access technology included in a frequency combination supported by the terminal device may include a combination of one or more frequencies (or frequency bands) under the first wireless access supported by the terminal device In the same way, the sub-frequency combination of the second wireless access technology included in a frequency combination supported by the terminal device may include one or more frequencies (or frequency bands) under the second wireless access supported by the terminal device The combination.

For example, please refer to Table 1, which is an example of an EN-DC frequency combination for terminal equipment:

Table 1

LTE子频率组合1LTE sub-frequency combination 1	NR子频率组合1NR sub-frequency combination 1
LTE子频率组合2LTE sub-frequency combination 2	NR子频率组合2NR sub-frequency combination 2
LTE子频率组合3LTE sub-frequency combination 3	NR子频率组合3NR sub-frequency combination 3

In Table 1, one row represents a frequency combination. For example, LTE sub-frequency combination 1 and NR sub-frequency combination 1 are a frequency combination supported by the terminal equipment. For example, LTE sub-frequency combination 1 may include one or more LTE frequencies (or frequency bands) supported by the terminal device. For example, NR sub-frequency combination 1 may include one or more NR frequencies (or frequency bands) supported by the terminal device. ). The same is true for other LTE sub-frequency combinations and NR sub-frequency combinations.

For example, the embodiment of the present application is applied to the network architecture shown in FIG. 2A. For example, the architecture in FIG. 2A is the EN-DC architecture, and at least one frequency combination supported by the terminal device may be referred to as the EN-DC frequency combination. The access technology is, for example, E-UTRA technology, and the second radio access technology is, for example, NR technology. Or, for example, the architecture of FIG. 2A is the EN-DC architecture, the at least one frequency combination supported by the terminal device may be referred to as the NE-DC frequency combination, the second wireless access technology is, for example, the E-UTRA technology, and the first wireless access technology The input technology is, for example, NR technology.

The at least one frequency combination supported by the terminal device may include a sub-frequency combination corresponding to the main network device under the dual connectivity architecture. In addition, sub-frequency combinations corresponding to other network devices other than the main network device may not be included, or sub-frequency combinations corresponding to other network devices other than the main network device may also be included. The main network device is, for example, the network device described above. For example, the frequency of the main network device is F1, and the main network device corresponds to the first wireless access technology. Then, the sub-frequency combination under the first radio access technology corresponding to each frequency combination in the at least one frequency combination supported by the terminal device may include the frequency F1; or, the frequency F1 may be included in the at least one frequency combination supported by the terminal device. The sub-frequency combination under the first wireless access technology corresponding to each frequency combination in some frequency combinations may include frequency F1, and there are also the first wireless access corresponding to each frequency combination in the remaining frequency combinations The sub-frequency combination under the technology may not include the frequency F1.

For example, the number of at least one frequency combination is 3, which are the first frequency combination, the second frequency combination, and the third frequency combination, respectively. The first frequency combination is the combination between LTE sub-frequency combination 1 and sub-frequency combination 2, the second frequency combination is the combination between LTE sub-frequency combination 3 and sub-frequency combination 4, and the third frequency combination is LTE sub-frequency combination 5 and sub-frequency. Combination between combination 6. For example, the main network device is an LTE network device, and the frequency of the main network device is F1, where LTE sub-frequency combination 1, LTE sub-frequency combination 3, and LTE sub-frequency combination 5 all include frequency F1, that is, the terminal device supports The sub-frequency combination under the first wireless access technology corresponding to each frequency combination in the at least one frequency combination includes the frequency of the main network device. Or, both LTE sub-frequency combination 3 and LTE sub-frequency combination 5 include frequency F1, but LTE sub-frequency combination 1 does not include frequency F1, that is, each of the partial frequency combinations in at least one frequency combination supported by the terminal device The sub-frequency combinations under the first wireless access technology corresponding to the two frequency combinations may include the frequency of the main network device, and each of the remaining frequency combinations corresponds to the sub-frequency combination under the first wireless access technology. The sub-frequency combination may not include the frequency of the main network device.

If the terminal device has the first measurement capability, it means that the terminal device can measure other sub-frequency combinations included in each frequency combination on one of the sub-frequency combinations included in each frequency combination in at least one of the supported frequency combinations . For example, the at least one frequency combination supported by the terminal device includes the first frequency combination, the second frequency combination, and the third frequency combination as described above. The first frequency combination is the combination between the LTE sub-frequency combination 1 and the NR sub-frequency combination 2, the second frequency combination is the combination between the LTE sub-frequency combination 3 and the NR sub-frequency combination 4, and the third frequency combination is the LTE sub-frequency Combination between combination 5 and NR sub-frequency combination 6. Then, if the terminal device has the first measurement capability, it indicates that the terminal device can measure the NR sub-frequency combination 2 in the LTE sub-frequency combination 1 and perform the NR sub-frequency combination 4 in the LTE sub-frequency combination 3 without the need for gap. Measurement, and the ability to measure NR sub-frequency combination 6 in LTE sub-frequency combination 5. Wherein, measuring one frequency combination on another frequency combination can be understood as measuring a cell under another frequency combination in a cell corresponding to one frequency combination. One frequency combination may correspond to one or more cells, and another frequency combination may also correspond to one or more cells. In theory, the terminal equipment can be in any cell corresponding to one frequency combination, and to any one of another frequency combination. The cell is measured.

Therefore, if the terminal device has the first measurement capability, the terminal device can indicate that the terminal device has the first measurement capability through the first indication information, and having the first measurement capability can instruct the terminal device to be able to configure the gap without configuring the gap. On one sub-frequency combination included in each frequency combination in at least one frequency combination, other sub-frequency combinations included in each frequency combination are measured. After the network device receives the first indication information, it can be determined that the terminal device can measure each frequency combination on a sub-frequency combination included in each frequency combination in at least one frequency combination without needing to configure the gap. Other sub-frequency combinations included.

For example, the first indication information may occupy one or more bits, taking one bit as an example. If the value of this 1 bit is "1", it indicates that the terminal device has the first measurement capability, indicating that the terminal device can be used in at least one frequency combination in each frequency combination without configuring the gap. In terms of frequency combinations, other sub-frequency combinations included in each frequency combination are measured; and if the value of this 1 bit is "0", it indicates that the terminal device does not have the first measurement capability, which means that the terminal device does not have the first measurement capability. On one sub-frequency combination included in each frequency combination in at least one frequency combination, it may be necessary to configure a gap to measure other sub-frequency combinations included in each frequency combination. In this case, the value of the first indication information can be used to determine whether the terminal device has the first measurement capability.

Or, no matter how many bits the first indication information occupies, if the terminal device sends the first indication information, it indicates that the terminal device has the first measurement capability, indicating that the terminal device can be used in at least one frequency combination without configuring the gap. On one of the sub-frequency combinations included in each frequency combination, measure the other sub-frequency combinations included in each frequency combination; and if the terminal device does not send the first indication information, the network device does not receive the first indication from the terminal device An indication information indicates that the terminal device does not have the first measurement capability, which means that if the terminal device measures the sub-frequency combination included in each frequency combination in at least one frequency combination, For other sub-frequency combinations, gap may need to be configured. In this case, there is no need to pay attention to the value of the first indication information.

In addition, as an optional manner, the first indication information may indicate that the terminal device has the first measurement capability, and also indicate that the terminal device has the second measurement capability. In this way, two kinds of information can be indicated by one indication message. Help save transmission overhead and improve bit utilization. For example, the first indication information may occupy one or more bits, taking 1 bit as an example. If the value of this 1 bit is "1", it indicates that the terminal device has the first measurement capability and the second measurement capability; and if the value of this 1 bit is "0", it indicates that the terminal device does not have the first measurement capability. Nor does it have a second measurement capability. In this case, the value of the first indication information can be used to determine whether the terminal device has the first measurement capability and the second measurement capability, and the terminal device will have both of these two measurement capabilities, or not both. Measurement capabilities.

Or, taking the first indication information occupies 2 bits as an example, one of the two bits is used to indicate the first measurement capability, and the other bit of the two bits is used to indicate the second measurement capability. For example, the high-order bit of the two bits indicates the first measurement capability, and the low-order bit indicates the second measurement capability. If the value of these 2 bits is "11", it indicates that the terminal device has the first measurement capability and the second measurement capability; if the value of these 2 bits is "00", it indicates that the terminal device does not have the first measurement capability. Does not have the second measurement capability; if the value of these 2 bits is "10", it indicates that the terminal device has the first measurement capability, but does not have the second measurement capability; if the value of these 2 bits is "01", It indicates that the terminal device does not have the first measurement capability, but has the second measurement capability.

Or, no matter how many bits the first indication information occupies, if the terminal device sends the first indication information, it indicates that the terminal device has the first measurement capability and the second measurement capability; and if the terminal device does not send the first indication information, the network device Failure to receive the first indication information from the terminal device indicates that the terminal device does not have the first measurement capability nor the second measurement capability. In this case, there is no need to pay attention to the value of the first indication information.

Or, as another optional manner, in addition to sending the first indication information to the network device, the terminal device may also send second indication information to the network device, and the second indication information may indicate that the terminal device has the second measurement capability, Refer to S32. Wherein, the first indication information and the second indication information may be carried in one message, or may also be carried in different messages. If the first indication information and the second indication information are carried in different messages, the terminal device may send the first indication information first and then the second indication information, or may send the second indication information first and then the first indication information, or The first instruction information and the second instruction information can be sent at the same time. Different indication information indicates the first measurement capability and the second measurement capability respectively, which can make the indication more clear.

For example, the second indication information may occupy one or more bits, taking 1 bit as an example. If the value of this 1 bit is "1", it indicates that the terminal device has the second measurement capability; and if the value of this 1 bit is "0", it indicates that the terminal device does not have the second measurement capability. In this case, the value of the second indication information can be used to determine whether the terminal device has the second measurement capability.

Or, no matter how many bits the second indication information occupies, if the terminal device sends the second indication information, it indicates that the terminal device has the second measurement capability; and if the terminal device does not send the second indication information, the network device does not receive the second indication information from the terminal device. The second indication information indicates that the terminal device does not have the second measurement capability. In this case, there is no need to pay attention to the value of the second indication information.

The second measurement capability is, for example, that the terminal device can measure the cell and each frequency in a cell under a sub-frequency combination included in each frequency combination in at least one frequency combination without needing to configure a gap. The time difference of the cell under the other sub-frequency combination included in the combination. Or, a more accurate description is that the second measurement capability can be that the terminal device can measure all the cells under a sub-frequency combination included in each frequency combination in at least one frequency combination without the need to configure the gap. The system frame number difference and frame boundary difference of the cell under the cell and the other sub-frequency combination included in each frequency combination.

For example, the second measurement capability may be referred to as the SFTD measurement capability, or the second measurement capability may also have other names, and there is no restriction on the name.

In addition, the terminal device may also send the information of at least one frequency combination to the network device, and the network device receives the information of the at least one frequency combination from the terminal device. In this way, the network device can know exactly which frequency combinations are supported by the terminal device, so that the network device can also know the application range of the first measurement capability.

Wherein, the terminal device may send the first indication information and the information of at least one frequency combination to the network device together, for example, carry it in a message and send it to the network device. The message is, for example, the terminal device reporting the capability of the terminal device to the network device. Messages, such as UE capability information (UE capability information) messages. Alternatively, the terminal device may also send the first indication information and the information of the at least one frequency combination separately, for example, the first indication information and the information of the at least one frequency combination are carried in different messages and sent to the network device. If the terminal device carries the first indication information and the information of at least one frequency combination in different messages and sends it to the network device, the terminal device may first send the first indication information and then send at least one frequency combination information, or send at least one frequency combination first. The first indication information is sent after the frequency combination information, or at least one frequency combination information and the first indication information may also be sent at the same time.

The first indication information is called SFTD capability information, for example, or may have other names. If the first indication information indicates that the terminal device has the first measurement capability and the second measurement capability, it is equivalent to indicating that the terminal device has the first measurement capability in addition to indicating that the terminal device has the SFTD measurement capability through the SFTD capability information. Ability to indicate multiple content through one type of information, which can save transmission overhead.

Alternatively, if the terminal device also sends the second indication information to the network device, the second indication information may be referred to as SFTD capability information, or may have other names. Equivalently, in the embodiment of the present application, in addition to indicating that the terminal device has the second measurement capability through SFTD capability information, it may also indicate that the terminal device has the first measurement capability through other indication information (first indication information).

S33. The network device configures the terminal device to measure the first frequency in the first cell, and according to the first indication information, determines not to configure the first measurement interval for the terminal device. The first measurement interval is used to measure the first frequency.

Knowing at least one frequency combination supported by the terminal device, the network device can configure the terminal device to perform a sub-frequency combination of each frequency combination in one or more frequency combinations of at least one frequency combination. Combine the other sub-frequency combinations for measurement. Of course, because the network device has a certain frequency, when the network device configures the terminal device for measurement, the frequency combination that can be configured by the terminal device for measurement needs to include the frequency of the network device in the included sub-frequency combination. The network device described in the embodiment of the present application is, for example, a main network device in a dual-connection architecture. Or, if the dual-connection architecture has not yet been formed, the network equipment here is the network equipment serving the terminal equipment.

For example, the at least one frequency combination supported by the terminal device includes a first frequency combination, a second frequency combination, and a third frequency combination. The first frequency combination is the combination between the LTE sub-frequency combination 1 and the NR sub-frequency combination 2, the second frequency combination is the combination between the LTE sub-frequency combination 3 and the NR sub-frequency combination 4, and the third frequency combination is the LTE sub-frequency Combination between combination 5 and NR sub-frequency combination 6. The network device is an LTE network device. For example, the terminal device currently accesses the first cell of the network device, and the frequency of the first cell is F1, so the network device can only configure the terminal device to measure other frequencies under the frequency F1. For example, if both LTE sub-frequency combination 1 and LTE sub-frequency combination 3 include frequency F1, the network device can configure the terminal device to measure NR sub-frequency combination 2 under frequency F1 (that is, in the first cell), or configure the terminal The device measures NR sub-frequency combination 4 under frequency F1 (that is, in the first cell), but because LTE sub-frequency combination 5 does not include frequency F1, network equipment cannot configure terminal equipment to perform NR sub-frequency combination 5 in LTE sub-frequency combination 5. Frequency combination 6 is measured.

For example, the current serving cell of the terminal device is the first cell, and the network device configures the terminal device to measure the first frequency in the first cell according to the information of at least one frequency combination, and the frequency of the first cell is different from the first frequency. For example, the first frequency belongs to a sub-frequency combination, for example, the first frequency belongs to the first sub-frequency combination, and the frequency of the first cell belongs to another sub-frequency combination, for example, the frequency of the first cell belongs to the second sub-frequency combination, and the first sub-frequency The combination and the second sub-frequency combination belong to one frequency combination in at least one frequency combination. Where the terminal device measures the first frequency in the first cell, it can be understood that the terminal device measures one or more cells under the first frequency in the first cell.

In addition, since the network device can determine that the terminal device has the first measurement capability according to the first indication information, when the network device configures the terminal device to measure the first frequency in the first cell, it does not need to configure the first measurement interval, that is, it does not need to be the terminal device. The first frequency configuration gap is measured in the first cell, because the terminal device can complete the measurement without the gap.

Among them, measuring the first frequency in the first cell can be understood as measuring the signal strength of each cell under the first frequency in the first cell. For example, the reference signal receiving power (RSRP) can be measured, and the reference signal receiving power can be measured. One or more of quality (reference signal receiving quality, RSRQ) or signal to interference plus noise ratio (SINR). In this way, the gap configuration can be reduced, and the transmission resources of the first cell can be fully utilized.

S34. The network device sends the first message to the terminal device, and the terminal device receives the first message from the network device.

The first message is used to configure the terminal device to measure the first frequency in the first cell, and the first message does not include the configuration of the first measurement interval, in other words, the first message does not include the configuration information of the first measurement interval, that is, The network device configures the terminal device to measure the first frequency in the first cell, and no gap is configured for the measurement of the terminal device.

After receiving the first message, the terminal device can measure the first frequency in the first cell without a gap. Wherein, measuring the first frequency in the first cell can be understood as measuring the signal strength of each cell under the first frequency in the first cell. For example, one or more of RSRP, RSRQ, or SINR of these cells can be measured.

In the embodiment of the present application, if the terminal device has the first measurement capability, it can inform the network device, and the network device can configure the terminal device to be within the capability of the terminal device to complete measurement of other frequencies without gaps. In this way, it is not necessary to configure gaps for terminal devices with allowable capabilities, so that the measurement process can be completed, transmission resources can be efficiently used, and the uplink and downlink throughput of the terminal devices can be improved.

The device used to implement the foregoing method in the embodiment of the present application will be described below in conjunction with the accompanying drawings. Therefore, the above content can all be used in the subsequent embodiments, and the repeated content will not be repeated.
