Description

Technical Field

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

[0002] In mobile communication systems, terminal devices perform measurements according to the measurement configuration issued by the base station and report the measurements to the base station. The base station then uses these reports to make mobility decisions or manage carriers. During communication with one or more serving cells, terminal devices measure neighboring cells to perform handover or cell reselection. Measurements include those of adjacent cells within the same system and those of cells in different systems. Neighboring cells may use different frequencies than the current serving cell. Due to limitations in terminal device capabilities, measurement gaps may need to be configured, for example, a 6ms measurement gap every 40ms. During these measurement gaps, the terminal device suspends data transmission in the serving cell to perform measurement operations. The base station does not schedule the terminal device during these measurement gaps. In Long Term Evolution (LTE) systems, terminal devices report capability information to the base station. Upon receiving this capability information, the base station determines whether a measurement gap is needed for the target band based on the terminal device's current operating frequency band and capability information. If a measurement gap is required, the base station then configures a measurement gap for the terminal device.

[0003] In 5G systems, one possible approach is to divide frequency resources into two frequency ranges (FR): FR1 and FR2. FR1 covers frequencies below 24 GHz, while FR2 covers frequencies from 24 GHz to 100 GHz. For example, LTE systems use frequency resources within FR1, while 5G systems can use frequency resources within either FR1 or FR2.

[0004] In 5G systems, terminal devices support a wide variety of frequency band combinations. A frequency band combination is a combination of frequency bands belonging to the serving cell supported by the carrier aggregation of the terminal device. This results in a large amount of capability information being reported by the terminal device, which cannot be sent to the network through a single signaling message over the air interface. This leads to very high signaling overhead and also high storage overhead for the base station. Summary of the Invention

[0005] This application provides a communication method and apparatus to reduce signaling overhead.

[0006] In a first aspect, this application provides a communication method, including:

[0007] Send capability information to the network device, wherein the capability information includes first capability information corresponding to a first frequency range and second capability information corresponding to a second frequency range, the first capability information including first indication information for indicating whether a frequency band within the first frequency range requires a measurement gap, and the second capability information including second indication information for indicating whether a frequency band within the second frequency range requires a measurement gap; receive measurement gap configuration information determined based on the capability information from the network device, wherein the measurement gap configuration information is information for configuring measurement gaps; and perform measurements based on the measurement gap configuration information.

[0008] By using the communication method provided in the first aspect, the first capability information corresponding to the first frequency range and the second capability information corresponding to the second frequency range are isolated and reported to the network device as independent information. This eliminates the need to report the combination of frequency bands corresponding to the first frequency range and the second frequency range, as well as the corresponding reporting of whether a measurement gap is required. Therefore, signaling overhead and storage overhead of the network device can be reduced.

[0009] In one possible design, the first capability information also includes a first frequency band list and a first frequency band combination list.

[0021] When the measurement gap type corresponds to the second frequency range, communication of the serving cell in the second frequency range is stopped within the measurement gap, and neighboring cells in the second frequency range are measured within the measurement gap; or,

[0026] The network device determines whether a measurement gap is needed for the target measurement frequency point based on the target measurement frequency point of the terminal device, the current operating frequency band combination of the terminal device, and capability information.

[0027] When a network device determines that a measurement gap is required for a target measurement frequency point, it sends measurement gap configuration information to the terminal device. The measurement gap configuration information is used to configure the measurement gap.

[0028] By using the communication method provided in the second aspect, the first capability information corresponding to the first frequency range and the second capability information corresponding to the second frequency range are isolated and reported to the network device as independent information. This eliminates the need to report the combination of frequency bands corresponding to the first frequency range and the second frequency range, as well as the corresponding reporting of whether a measurement gap is required. Therefore, signaling overhead and storage overhead of the network device can be reduced.

The second frequency band combination list is a list of frequency band combinations within the second frequency range supported by the terminal device. The second indication information includes an indication of whether each frequency band in the second frequency band list corresponding to each frequency band combination in the second frequency band combination list needs to measure the gap.

[0034] In one possible design, some or all of the frequency band combinations in the first frequency band combination list or the second frequency band combination list are indicated by frequency band identification or by combination conditions.

[0035] The communication method provided by this embodiment can further reduce signaling overhead by indicating some or all frequency band combinations in the first frequency band combination list or the second frequency band combination list through combination conditions.

[0036] In one possible design, the combination conditions include at least one of the following:

[0037] The number of frequency bands in the frequency band combination is equal to or less than the first value; or...

[0038] The maximum bandwidth of the serving cell corresponding to the frequency band in the frequency band combination shall not exceed the second value; or

[0039] The total bandwidth of all serving cells corresponding to the frequency bands in the frequency band combination does not exceed the third value; or

[0040] The total number of all serving cells corresponding to the frequency bands in the frequency band combination shall not exceed the fourth value.

[0041] In one possible design, the network device determines whether a measurement gap is needed for the target measurement frequency point based on the first capability information and the first frequency band combination, including:

[0042] The network device determines whether a measurement gap is needed for the target measurement frequency point based on the first indication information and the first frequency band combination; or,

[0043] If the first frequency band combination list includes a frequency band combination consisting of the first frequency band combination and the frequency band to which the target measurement frequency point belongs, then the network device determines that the target measurement frequency point does not require a measurement gap.

[0044] In one possible design, the network device determines whether a measurement gap is required for the target measurement frequency point based on the second capability information and the second frequency band combination, including:

[0045] The network device determines whether a measurement gap is required for the target measurement frequency point based on the second indication information and the second frequency band combination; or,

[0046] If the second frequency band combination list includes a frequency band combination consisting of the second frequency band combination and the frequency band to which the target measurement frequency point belongs, then the network device determines that the target measurement frequency point does not require a measurement gap.

[0047] In one possible design, the measurement gap configuration information includes: measurement gap configuration and measurement gap type, wherein the measurement gap type is one of the measurement gap corresponding to the terminal device, the measurement gap corresponding to a first frequency range, and the measurement gap corresponding to a second frequency range.

[0048] In one possible design, the measurement gap configuration information includes: a first measurement gap configuration and a type of the first measurement gap, a second measurement gap configuration and a type of the second measurement gap, wherein the type of the first measurement gap is a measurement gap corresponding to a first frequency range, and the type of the second measurement gap is a measurement gap corresponding to a second frequency range.

[0049] In one possible design, the first frequency range is 0 to 24 GHz, and the second frequency range is 24 GHz to 100 GHz.

[0050] Thirdly, this application provides a communication method, including:

[0051] The network device receives capability information, which includes first capability information corresponding to a first frequency range and second capability information corresponding to a second frequency range. The first capability information includes a first frequency band list and a first frequency band combination list, and the second capability information includes a second frequency band list and a second frequency band combination list. The network device determines the frequency band combinations supported by the terminal device based on the first frequency band combination list and the second frequency band combination list.

[0052] With the communication method provided by the third aspect, the terminal device does not need to report separate indication information on whether the gap needs to be measured. The network can determine whether the gap needs to be measured based on the first frequency band combination list or the second frequency band combination list in the capability information reported by the terminal device, thereby reducing the size (or dimension) of the capability information reported by the terminal device, reducing signaling overhead, and also reducing the storage overhead of the network device.

[0053] In one possible design, the method further includes: the network device determining whether a measurement gap is required for the target measurement frequency based on the target measurement frequency of the terminal device, the current operating frequency band combination of the terminal device, and capability information.

[0055] Fourthly, this application provides a communication method, including:

[0056] The terminal device receives third measurement gap configuration information from the LTE network device. When the terminal device receives a message from the LTE network device to add an NR cell as a serving cell, or receives measurement configuration information for an NR frequency point from the LTE network device, it deletes the third measurement gap configuration information.

[0057] By using the communication method provided in the third aspect, the measurement gap configured in the LTE system is deleted by the terminal device, which solves the problem that after the terminal device receives a message to add an NR cell as a serving cell or receives a measurement configuration for an NR frequency point, the measurement gap configured in LTE does not indicate the type, and it is unclear whether the measurement gap can be used to measure neighboring cells of FR2.

[0058] In one possible design, the method further includes: the terminal device receiving fourth measurement gap configuration information from the network device, and the terminal device measuring the target measurement frequency point according to the measurement gap configuration information.

[0060] Through the communication method provided in the fifth aspect, the network device configures the fifth measurement gap configuration information, and the fifth measurement gap configuration information carries the type of measurement gap, thereby avoiding the problem of uncertainty about whether the measurement gap can be used to measure the neighboring cell of FR2 due to not carrying the type of measurement gap.

[0061] In one possible design, the method also includes:

[0062] The terminal device receives a message from the LTE network device to add an NR cell as a serving cell or receives the measurement configuration for the NR frequency point sent by the LTE network device. The terminal device performs measurements on the target measurement frequency point according to the configuration information of the fifth measurement interval.

[0063] The communication method provided in this embodiment configures a measurement gap for the terminal device through the LTE network device and indicates the type of measurement gap. Thus, when the terminal device receives a message to add an NR cell as a serving cell or receives a measurement configuration for an NR frequency point, the terminal device can determine whether the measurement gap can be used to measure the neighboring cells of FR2 according to the fifth measurement gap configuration information.

[0065] The communication method provided in the sixth aspect solves the problem of how to configure measurement gaps after the serving cell of the terminal device changes.

[0066] In a seventh aspect, this application provides a communication method, comprising: a terminal device receiving a message from a network device for adding or deleting a serving cell, or a message for adding or deleting a measurement frequency point; the terminal device determining whether a measurement gap is currently needed; if no measurement gap is needed, sending an indication message indicating that a measurement gap is not needed or a request message for releasing a measurement gap to the network device; if a measurement gap is needed, sending a requirement for a measurement gap indication message or a request message for configuring a measurement gap to the network device, wherein the indication message or request message also carries the type of the required measurement gap.

[0067] The communication method provided in the seventh aspect solves the problem of how to configure measurement gaps after adding or deleting serving cells, or adding or deleting measurement frequencies, without the need to report capability information, thus reducing signaling overhead.

[0068] Eighthly, this application provides a communication device, including a module, component, or circuit for implementing the communication method in the first aspect and any possible design of the first aspect, or the communication method in the second aspect and any possible design of the second aspect, or the communication method in the third aspect and any possible design of the third aspect, or the communication method in the fourth aspect and any possible design of the fourth aspect, or the communication method in the fifth aspect and any possible design of the fifth aspect, or the communication method in the sixth aspect and any possible design of the sixth aspect, or the communication method in the seventh aspect and any possible design of the seventh aspect.

[0089] The embodiments of this application can be applied to wireless communication systems. It should be noted that the wireless communication systems mentioned in the embodiments of this application include, but are not limited to: Narrow Band-Internet of Things (NB-IoT), Global System for Mobile Communications (GSM), Enhanced Data Rate for GSM Evolution (EDGE), Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access 2000 (CDMA2000), Time Division-Synchronization Code Division Multiple Access (TD-SCDMA), Long Term Evolution (LTE), and next-generation 5G mobile communication systems.

[0090] The communication devices involved in this application mainly include network equipment and terminal equipment.

[0091] Network equipment: This can be a base station, an access point, or an access network device, or it can refer to a device in the access network that communicates with a wireless terminal via one or more sectors on the air interface. Network equipment can be used to convert received air frames to and from IP packets, and act as a router between the wireless terminal and the rest of the access network, which may include an Internet Protocol (IP) network. Network equipment can also coordinate the management of air interface attributes. For example, network equipment can be an evolved Node B (eNB or eNodeB) in Long Term Evolution (LTE), a relay station or access point, or a base station in a 5G network, such as a gNB, etc., without limitation.

[0092] Terminal equipment: This can be a wireless terminal or a wired terminal. A wireless terminal can be a device that provides voice and / or other service data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The wireless terminal can communicate with one or more core networks via the RAN. The wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, for example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device that exchanges voice and / or data with the wireless access network. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). Wireless terminals can also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile stations, remote stations, remote terminals, access terminals, user terminals, user agents, user devices, or user equipment, without any specific definition here.

[0093] Figure 1 This is a schematic diagram of a communication system architecture, such as... Figure 1As shown, the communication system in this application embodiment may include one or more network devices and one or more terminal devices, and the network devices and terminal devices communicate with each other.

[0094] Due to the introduction of high frequencies, frequency resources can be divided into two or more ranges. Taking two ranges as an example, such as FR1 and FR2, FR1 is below 24GHz, and FR2 is from 24GHz to 100GHz. If the existing capability information reporting method is still used, the terminal device reports capability information to the base station. The capability information includes a list of frequency bands supported by the terminal device (this band list includes the frequency bands of FR1 and FR2), a list of frequency band combinations supported by the terminal device (this frequency band combination list also needs to include frequency band combinations of FR1 and FR2), and measurement capabilities. The measurement capabilities include whether each band in the measurement band list needs to be measured under each frequency band combination in the frequency band combination list. The indication of gaps, for example, if a terminal device supports 10 frequency bands, of which 5 are bands in FR1: Band1, Band2, Band3, Band4, and Band5, and 5 are bands in FR2: Band6, Band7, Band8, Band9, and Band10, the terminal device can support a large number of frequency band combinations, and the corresponding measurement capabilities also need to be indicated in the same number. Therefore, the signaling overhead will be very large. To solve this problem, this application provides a communication method that separates the first capability information corresponding to the first frequency range (such as FR1) and the second capability information corresponding to the second frequency range (such as FR2) and reports them as independent information to the network device, thereby reducing the signaling overhead. It should be noted that the communication method provided in this application does not limit the frequency division for each frequency range, nor is it limited to two frequency ranges, nor is it limited to the frequency ranges exemplified above. It can be applied to the division of more frequency ranges, such as three frequency ranges. Similar to the method in this application, the first capability information corresponding to the first frequency range, the second capability information corresponding to the second frequency range, and the third capability information corresponding to the third frequency range are reported to the network device as independent information, all of which are within the protection scope of this application. The communication method and apparatus provided in this application are described in detail below with reference to the accompanying drawings.

[0095] Figure 2 An interactive flowchart of an embodiment of a communication method provided in this application is shown below. Figure 2 As shown, the method in this embodiment may include:

[0096] S101. The terminal device sends capability information to the network device, wherein the capability information includes first capability information corresponding to a first frequency range and second capability information corresponding to a second frequency range. The first capability information includes first indication information indicating whether a measurement gap is needed for a frequency band within the first frequency range, and the second capability information includes second indication information indicating whether a measurement gap is needed for a frequency band within the second frequency range.

[0097] It is understood that in the embodiments of this application, the first capability information and the second capability information are independent information. For example, the first capability information and the second capability information are two different fields or information elements in the capability information, and the frequency band list in the first capability information and the frequency band list in the second capability information are placed in different frequency band lists.

[0098] In one possible approach, the first capability information corresponding to a first frequency range can be information related to a frequency band within the first frequency range, and the second capability information corresponding to a second frequency range can be information related to a frequency band within the second frequency range. For example, the first frequency range and the second frequency range are FR1 and FR2, respectively. FR1 is below 24 GHz, and FR2 is from 24 GHz to 100 GHz. Considering the different characteristics of high and low frequencies, such as the fact that high and low frequency receivers of terminal devices cannot share and are independent receivers, this embodiment of the application separates the FR1-related capabilities and FR2-related capabilities in terms of carrier aggregation capabilities and the capability to measure whether a measurement gap is required, so that they do not affect each other. In this embodiment, the first capability information corresponding to the first frequency range and the second capability information corresponding to the second frequency range are reported to the network device independently. Compared with the capability information reporting method in the prior art, this eliminates the reporting of frequency band combinations between the bands corresponding to the first frequency range and the bands of the second frequency range, as well as the reporting of the corresponding indication of whether a measurement gap is required, thus reducing signaling overhead. For example, in FR1, the terminal device supports 5 frequency bands: Band1, Band2, Band3, Band4, and Band5. In FR2, the terminal device supports 10 frequency bands: Band6, Band7, Band8, Band9, Band10, Band11, Band12, Band13, Band14, and Band15. Taking a terminal device supporting 2 frequency bands as an example, C1 is eliminated. 2 5-C5 2 - Reporting of C120 frequency band combinations and corresponding indications of whether gap measurement is required.

[0099] In this embodiment, optionally, the first capability information further includes a first frequency band list and a first frequency band combination list. The first frequency band list is a list of all frequency bands within a first frequency range supported by the terminal device. The first frequency band combination list is a list of frequency band combinations within the first frequency range supported by the terminal device. A frequency band combination within the first frequency range is a combination of frequency bands consisting only of frequency bands within the first frequency range, and the frequency band combination is a combination of frequency bands belonging to the serving cell of the carrier aggregation supported by the terminal device. The first indication information includes an indication of whether each frequency band in the first frequency band list corresponding to each frequency band combination in the first frequency band combination list requires a measurement gap. Each frequency band in the first frequency band list refers to the neighboring cell under that frequency band being measured.

[0100] The second capability information also includes a second frequency band list and a second frequency band combination list. The second frequency band list is a list of all frequency bands within the second frequency range supported by the terminal device. The second frequency band combination list is a list of frequency band combinations within the second frequency range supported by the terminal device. The frequency band combination within the second frequency range is a combination of frequency bands consisting only of frequency bands within the second frequency range. The second indication information includes an indication of whether each frequency band in the second frequency band list corresponding to each frequency band combination in the second frequency band combination list needs to measure the gap.

[0101] The frequency band combinations in the first or second frequency band combination list are indicated by frequency band identifier combinations. Specifically, the frequency band combinations in the first frequency band combination list are identifier combinations of frequency bands within a first frequency range, and the frequency band combinations in the second frequency band combination list are identifier combinations of frequency bands within a second frequency range. For example, a frequency band combination in the first frequency band combination list might be Band1+Band2+Band3, and a frequency band combination in the second frequency band combination list might be Band6+Band8+Band9+Band10. Here, Band1, Band2, Band3, Band6, Band8, Band9, and Band10 are all frequency band identifiers.

[0102] The first indication information can indicate whether a measurement gap is required for each frequency band in the first frequency band list corresponding to each frequency band combination in the first frequency band combination list. Table 1 shows one possible form of indicating whether a measurement gap is required for each frequency band in the first frequency band list corresponding to each frequency band combination in the first frequency band combination list. Taking a first frequency range of FR1 and a second frequency range of FR2 as an example, when the first capability information includes a first frequency band list (including 5 frequency bands: FR1-1, FR1-2, FR1-3, FR1-4, and FR1-5) and a first frequency band combination list (including 7 frequency band combinations: FR1BC-1, FR1BC-2, FR1BC-3, FR1BC-4, FR1BC-5, FR1BC-6, and FR1BC-7), an exemplary method is given for indicating whether a measurement gap is required for each frequency band in the first frequency band list corresponding to each frequency band combination in the first frequency band combination list (represented by GAP? in the table). The above indication can be expressed as "yes" or "no" using one bit or other means.

[0103] Table 1

[0104] FR1-1 FR1-2 FR1-3 FR1-4 FR1-5 FR1BC-1 GAP? GAP? GAP? GAP? GAP? FR1BC-2 GAP? GAP? GAP? GAP? GAP? FR1BC-3 GAP? GAP? GAP? GAP? GAP? FR1BC-4 GAP? GAP? GAP? GAP? GAP? FR1BC-5 GAP? GAP? GAP? GAP? GAP? FR1BC-6 GAP? GAP? GAP? GAP? GAP? FR1BC-7 GAP? GAP? GAP? GAP? GAP?

[0105] The second indication information can indicate whether a measurement gap is required for each frequency band in the second frequency band list corresponding to each frequency band combination in the second frequency band combination list. Table 2 shows one possible form for indicating whether a measurement gap is required for each frequency band in the second frequency band list corresponding to each frequency band combination in the second frequency band combination list. Taking a first frequency range of FR1 and a second frequency range of FR2 as an example, when the second capability information includes a second frequency band list (including 5 frequency bands: FR2-1, FR2-2, FR2-3, FR2-4, and FR2-5) and a second frequency band combination list (including 8 frequency band combinations: FR2BC-1, FR2BC-2, FR2BC-3, FR2BC-4, FR2BC-5, FR2BC-6, FR2BC-7, and FR2BC-8), an exemplary method for indicating whether a measurement gap is required for each frequency band in the second frequency band list corresponding to each frequency band combination in the second frequency band combination list is given (denoted as GAP? in the table). The above indication can be expressed as "yes" or "no" using one bit or other methods.

[0106] Table 2

[0107]

[0108]

[0109] As shown in Tables 1 and 2, the first capability information corresponding to FR1 and the second capability information corresponding to FR2 are reported as independent information. Since the indication of whether a measurement gap is required for the frequency band combination corresponding to FR1 is only associated with the frequency bands under FR1 supported by the terminal equipment, and not with the frequency bands under FR2, and the indication of whether a measurement gap is required for the frequency band combination corresponding to FR2 is only associated with the frequency bands under FR2 supported by the terminal equipment, and not with the frequency bands under FR1, the signaling overhead is reduced.

[0110] Optionally, to further reduce signaling overhead, some or all frequency band combinations in the first frequency band combination list or the second frequency band combination list are indicated by combination conditions.

[0111] The combination conditions include at least one of the following:

[0112] The number of frequency bands in a frequency band combination is equal to or less than the first value. For example, the number of frequency bands included in a frequency band combination is equal to or less than 3. A frequency band combination refers to the combination of frequency bands belonging to the serving cells of the carrier aggregation supported by the terminal equipment. Different serving cells use the same frequency band resources, and the frequency bands of these serving cells can be considered as one.

[0113] Alternatively, the maximum bandwidth of the serving cell corresponding to the frequency band in the frequency band combination does not exceed the second value; for example, the maximum bandwidth of the serving cell corresponding to the frequency band in the frequency band combination does not exceed 20MHz; or

[0114] The total bandwidth of all serving cells corresponding to the frequency bands in a frequency band combination shall not exceed the third value. For example, if the frequency band combination includes 3 frequency bands, the total bandwidth of all serving cells corresponding to the 3 frequency bands shall not exceed 100MHz; or

[0115] The total number of serving cells corresponding to the frequency bands in a frequency band combination shall not exceed the fourth value. For example, the total number of serving cells corresponding to the frequency bands in a frequency band combination shall not exceed 4.

[0116] For example, the combination conditions can also be: the number of frequency bands in the frequency band combination is equal to or less than 3, and the maximum bandwidth of the serving cell corresponding to the frequency band in the frequency band combination does not exceed 40MHz.

[0117] In other words, the frequency band combination indicated by the combination condition may actually be multiple frequency band combinations that satisfy that combination condition. These multiple frequency band combinations have the same indication of whether a measurement gap is required, thereby further reducing signaling overhead.

[0118] S102. The network device determines whether a measurement gap is needed for the target measurement frequency point based on the target measurement frequency point of the terminal device, the current operating frequency band combination of the terminal device, and capability information.

[0119] The target measurement frequency point is the frequency point that the network device sends to the terminal device for measurement. The current operating frequency band combination of the terminal device is the combination of the frequency bands to which the frequency resources of all the serving cells of the terminal device belong. For example, if the terminal device has 3 serving cells, and the frequency resources they use belong to Band 1, Band 3, and Band 6 respectively, then the current operating frequency band combination of the terminal device is Band 1 + Band 3 + Band 6. It can be understood that the network device may send one or more frequency points to the terminal device for measurement. Each frequency point that the terminal device needs to measure can be regarded as a target measurement frequency point. The method for determining the required measurement interval for each target measurement frequency point is similar.

[0120] As an implementable approach, S102 can specifically be:

[0121] If the target measurement frequency point belongs to the first frequency range, the network device determines whether the target measurement frequency point needs a measurement gap based on the first capability information and the first frequency band combination. The first frequency band combination is the frequency band combination that belongs to the first frequency range in the frequency band combination currently operated by the terminal device. If the target measurement frequency point belongs to the second frequency range, the network device determines whether the target measurement frequency point needs a measurement gap based on the second capability information and the second frequency band combination. The second frequency band combination is the frequency band combination that belongs to the second frequency range in the frequency band combination currently operated by the terminal device.

[0122] Taking a first frequency range of FR1 and a second frequency range of FR2 as an example, if the target measurement frequency point belongs to FR1, the need for a measurement gap is determined based on the frequency band combinations within FR1 currently operating in the terminal device (i.e., the first frequency band combination, excluding the FR2 serving cell) and the first capability information. For example, if the terminal device's current operating frequency band combinations are FR1-1, FR1-2, FR2-1, and FR2-2, where FR1-1 and FR1-2 are frequency bands under FR1, and FR2-1 and FR2-2 are frequency bands under FR2, then the frequency band combination within the first frequency range in the current operating frequency band combination is the combination of FR1-1 and FR1-2 (i.e., the first frequency band combination is the combination of FR1-1 and FR1-2), and the frequency band combination within the second frequency range in the current operating frequency band combination is the combination of FR2-1 and FR2-2 (i.e., the second frequency band combination is the combination of FR2-1 and FR2-2). When measuring FR1-x, the combination of FR1-1 and FR1-2 determines whether a measurement gap is needed. Similarly, when measuring FR2-x, the combination of FR2-1 and FR2-2 determines whether a measurement gap is needed. The first or second frequency band combination may be empty or consist of only one band. If the first or second frequency band combination is empty, the network device determines that a measurement gap is not needed because it indicates the terminal device is fully capable of measuring the target frequency without requiring a gap. If the first or second frequency band combination consists of only one band, the need for a measurement gap can be determined based on existing indications or other methods; this application does not limit the specific method used. Alternatively, if no serving cell in the current serving cell is in the same FR as the target frequency, then measuring the target frequency does not require a measurement gap.

[0123] Optionally, if the terminal device supports a certain frequency band combination, by default, when the frequency band combination currently used by the terminal device is a subset of that frequency band combination, no gap is needed for measuring frequency bands other than that subset. For example, if the frequency band combination consists of four bands (x1, x2, x3, x4), if the currently used frequency band combination is x1 and x2, no gap is needed for measuring x3 and x4; if the currently used frequency band combination is x1, x2, and x3, no gap is needed for measuring x4. That is, when the terminal device supports aggregation of the currently used frequency band combination plus the frequency band to which the target measurement frequency belongs (or in other words, when the terminal device supports adding the frequency band to which the target measurement frequency belongs as the serving cell under the currently used frequency band combination), no gap is needed, thereby reducing the size of the capability information reported by the terminal device and reducing signaling overhead.

[0124] Optionally, the network device determines whether a measurement gap is needed for the target measurement frequency point based on the first capability information and the first frequency band combination. This can include: the network device determining whether a measurement gap is needed for the target measurement frequency point based on the first indication information and the first frequency band combination. For example, the network device directly determines whether a measurement gap is needed for the target measurement frequency point based on the indication in the first indication information regarding whether a measurement gap is needed for the frequency band to which the target measurement frequency point belongs. Alternatively,

[0125] If the first frequency band combination list includes a frequency band combination consisting of the first frequency band combination and the frequency band to which the target measurement frequency point belongs, the network device determines that the target measurement frequency point does not require a measurement gap. If the first frequency band combination list does not include a frequency band combination consisting of the first frequency band combination and the frequency band to which the target measurement frequency point belongs, the network device determines whether the target measurement frequency point requires a measurement gap based on the first indication information. Optionally, the network device can determine whether the target measurement frequency point requires a measurement gap based on the first capability information and the first frequency band combination by: firstly determining whether the first frequency band combination list includes a frequency band combination consisting of the first frequency band combination and the frequency band to which the target measurement frequency point belongs; if the first frequency band combination list includes a frequency band combination consisting of the first frequency band combination and the frequency band to which the target measurement frequency point belongs, then directly determining that the target measurement frequency point does not require a measurement gap; if the first frequency band combination list does not include a frequency band combination consisting of the first frequency band combination and the frequency band to which the target measurement frequency point belongs, then determining whether the target measurement frequency point requires a measurement gap based on the first indication information and the first frequency band combination.

[0126] Optionally, the network device determines whether a measurement gap is needed for the target measurement frequency point based on the second capability information and the second frequency band combination. Specifically, the network device determines whether a measurement gap is needed for the target measurement frequency point based on the second indication information and the second frequency band combination. For example, the network device directly determines whether a measurement gap is needed for the target measurement frequency point based on the indication in the second indication information regarding whether a measurement gap is needed for the frequency band to which the target measurement frequency point belongs. Alternatively,

[0127] If the second frequency band combination list includes a frequency band combination consisting of the second frequency band combination and the frequency band to which the target measurement frequency point belongs, the network device determines that the target measurement frequency point does not require a measurement gap. If the second frequency band combination list does not include a frequency band combination consisting of the second frequency band combination and the frequency band to which the target measurement frequency point belongs, the network device determines whether the target measurement frequency point requires a measurement gap based on the second indication information. Optionally, the network device can determine whether the target measurement frequency point requires a measurement gap based on the second capability information and the second frequency band combination as follows: The network device first determines whether the second frequency band combination list includes a frequency band combination consisting of the second frequency band combination and the frequency band to which the target measurement frequency point belongs. If the second frequency band combination list includes a frequency band combination consisting of the second frequency band combination and the frequency band to which the target measurement frequency point belongs, then it directly determines that the target measurement frequency point does not require a measurement gap. If the second frequency band combination list does not include a frequency band combination consisting of the second frequency band combination and the frequency band to which the target measurement frequency point belongs, then it determines whether the target measurement frequency point requires a measurement gap based on the second indication information and the second frequency band combination.

[0128] Optionally, in this embodiment, the first frequency band list, the first frequency band combination list, and the first indication information may be reported in different information cells, and the second frequency band list, the second frequency band combination list, and the second indication information may be reported in different information cells. In one possible approach, the capability information may be sent by the terminal device based on a request from the network device.

[0129] S103. When the network device determines that a measurement gap is required for the target measurement frequency point, it sends measurement gap configuration information to the terminal device.

[0130] The measurement gap configuration information is used to configure the measurement gap. Optionally, the measurement gap configuration information may include: measurement gap configuration and measurement gap type. The measurement gap type can be one of the following: a measurement gap corresponding to the terminal device, a measurement gap corresponding to a first frequency range, or a measurement gap corresponding to a second frequency range. The measurement gap configuration may include: the period and / or length of the measurement gap. Optionally, when two measurement frequencies are both within the first frequency range or both within the second frequency range, and both measurement frequencies require a measurement gap, only one measurement gap can be configured, and the two measurement frequencies can share this single measurement gap.

[0131] It should be noted that when there are multiple target measurement frequencies, the measurement gap configuration information for each measurement frequency is sent in a single message.

[0132] It should be noted that in this embodiment, the terminal device sends capability information to the network device. Taking the network device as a base station as an example, the receiving network device can be the main base station, which then sends the capability information to the auxiliary base station. The sending of measurement gap configuration information to the terminal device can be either the main base station or the auxiliary base station (that is, S102 and S103 can be implemented by either the main base station or the auxiliary base station). Alternatively, the network device receiving the capability information and the network device sending the measurement gap configuration information to the terminal device can be the same network device.

[0133] Optionally, if the network device configures an independent measurement gap for the terminal device (i.e., a measurement gap corresponding to a frequency range), and the terminal device supports independent measurement gaps, then during the measurement gap, the terminal device terminates data transmission with the serving cell of the corresponding FR, while other serving cells can continue data transmission. Optionally, the indication information that the terminal device supports independent measurement gaps can be carried in the capability information. If the terminal device supports independent measurement gaps, and the independent measurement gaps include measurement gaps corresponding to a first frequency range and measurement gaps corresponding to a second frequency range, then for a given target measurement frequency, the type of measurement gap can be one of the measurement gaps corresponding to the terminal device, the measurement gap corresponding to the first frequency range, and the measurement gap corresponding to the second frequency range. If the terminal device does not support independent measurement gaps, then for a given target measurement frequency, the type of measurement gap is the measurement gap corresponding to the terminal device.

[0134] Optionally, the measurement gap configuration information includes: a first measurement gap configuration and a type of the first measurement gap, a second measurement gap configuration and a type of the second measurement gap. The first measurement gap configuration includes the period and / or length of the first measurement gap, and the second measurement gap configuration includes the period and / or length of the second measurement gap. The type of the first measurement gap is a measurement gap corresponding to a first frequency range, and the type of the second measurement gap is a measurement gap corresponding to a second frequency range. That is, the network device configures two measurement gaps for the terminal device and indicates the types of the two measurement gaps. For example, when the frequency points to be measured include two measurement frequency points, one in the first frequency range and one in the second frequency range, and both measurement frequency points require measurement gaps, two measurement gaps can be configured simultaneously. The network device configures two measurement gaps, one corresponding to the first frequency range and the other corresponding to the second frequency range, and the two measurement gaps are configured simultaneously.

[0135] S104. The terminal equipment measures the target measurement frequency point according to the measurement gap configuration information.

[0136] In one possible approach, when the measurement gap type is a measurement gap corresponding to a first frequency range, communication in the serving cell of the first frequency range is stopped within the measurement gap, and neighboring cells of the first frequency range are measured within the measurement gap according to the measurement gap configuration, wherein the measurement gap is obtained according to the measurement gap configuration. Alternatively, when the measurement gap type is a measurement gap corresponding to a second frequency range, communication in the serving cell of the second frequency range is stopped within the measurement gap according to the measurement gap configuration, and neighboring cells of the second frequency range are measured within the measurement gap. Alternatively, when the measurement gap type is a measurement gap corresponding to a terminal device, communication in all serving cells is stopped within the measurement gap according to the measurement gap configuration, and neighboring cells of both the first and second frequency ranges are measured within the measurement gap.

[0137] The communication method provided in this embodiment involves a terminal device sending capability information to a network device. This capability information includes first capability information corresponding to a first frequency range and second capability information corresponding to a second frequency range. The first and second capability information are independent. The first capability information includes first indication information indicating whether a measurement gap is needed for a frequency band within the first frequency range, and the second capability information includes second indication information indicating whether a measurement gap is needed for a frequency band within the second frequency range. The network device then determines whether a measurement gap is needed for the target measurement frequency point based on the terminal device's target measurement frequency, the current operating frequency band combination of the terminal device, and the capability information. If a measurement gap is determined to be needed, the network device sends measurement gap configuration information to the terminal device. Finally, the terminal device performs measurements on the target measurement frequency point according to the measurement gap configuration information. By isolating the first capability information corresponding to the first frequency range and the second capability information corresponding to the second frequency range and reporting them to the network device as independent information, the reporting of frequency band combinations corresponding to the first and second frequency ranges, as well as the corresponding indication of whether a measurement gap is needed, is eliminated. This reduces signaling overhead and also reduces the storage overhead of the network device.

[0138] The following is a specific embodiment to illustrate... Figure 2 The technical solutions of the illustrated method embodiments will be described in detail.

[0139] This embodiment uses FR1 and FR2 as examples, with FR1 being below 24 GHz and FR2 being from 24 GHz to 100 GHz. Figure 3 An interactive flowchart of an embodiment of a communication method provided in this application is shown below. Figure 3 As shown, the method in this embodiment may include:

[0140] S201. The terminal device sends capability information to the network device. The capability information includes first capability information corresponding to FR1 and second capability information corresponding to FR2. The first capability information and the second capability information are independent information. The first capability information includes a first frequency band list, a first frequency band combination list, and first indication information for indicating whether a measurement gap is needed for a frequency band within FR1. The second capability information includes a second frequency band list, a second frequency band combination list, and second indication information for indicating whether a measurement gap is needed for a frequency band within FR2.

[0141] When the first capability information includes a first frequency band list (comprising 5 frequency bands: Band1, Band2, Band3, Band4, and Band5) and a first frequency band combination list (comprising 4 frequency band combinations: Band1+Band2, Band1+Band4, Band1+Band2+Band5, and Band2+Band3+Band4), Table 3 exemplarily provides one possible way to indicate whether each frequency band in the first frequency band list corresponding to each frequency band combination in the first frequency band combination list needs a measurement gap (indicated by 1 and 0 in the table), where 1 indicates "yes" (a measurement gap is required) and 0 indicates "no" (a measurement gap is not required). In this embodiment, the first frequency band list, the first frequency band combination list, and the first indication information can be reported separately in different information cells, and the second frequency band list, the second frequency band combination list, and the second indication information can be reported separately in different information cells. In one possible approach, the capability information can be sent by the terminal device based on a request from the network device.

[0142] Table 3

[0143]

[0144]

[0145] When the second capability information includes a second frequency band list (comprising 5 frequency bands: Band6, Band7, Band8, Band9, and Band10) and a second frequency band combination list (comprising 6 frequency band combinations: Band6+Band7, Band9+Band10, Band6+Band7+Band8, Band8+Band9+Band10, Band6+Band10, and Band7+Band9+Band10), Table 4 provides an example of one possible way to indicate whether each frequency band in the second frequency band list corresponding to each frequency band combination in the second frequency band combination list needs to measure the gap (indicated by 1 and 0 in the table), where 1 indicates "yes" and 0 indicates "no".

[0146] Table 4

[0147] Band6 Band7 Band8 Band9 Band10 Band6+Band7 1 1 0 0 1 Band9+Band10 0 0 1 1 0 Band6+Band7+Band8 1 1 1 0 1 Band8+Band9+Band10 1 0 1 1 1 Band6+Band10 1 1 0 0 1 Band7 + Band9 + Band10 1 0 1 1 1

[0148] In this embodiment, the frequency band combinations in the first frequency band combination list or the second frequency band combination list are indicated by frequency band identifier combinations.

[0149] Optionally, another indication method can further reduce signaling overhead. As shown in Table 5, all or part of the frequency band combinations in the first or second frequency band combination list are indicated by combination conditions. In this embodiment, taking the combination condition of the number of frequency bands in the frequency band combination being equal to or less than 2 as an example, in Table 5, as long as the number of frequency bands in the frequency band combination is less than or equal to 2, the indication of whether a measurement gap is required is the same. For example, for frequency band combinations Band1+Band2 and Band1+Band4, the indication of whether a measurement gap is required for each frequency band in the first frequency band list corresponding to these two frequency band combinations is the same.

[0150] Table 5

[0151]

[0152] S202. The network device determines whether a measurement gap is needed for the target measurement frequency point based on the target measurement frequency point of the terminal device, the current operating frequency band combination of the terminal device, and capability information.

[0153] For example, assuming the target measurement frequency is 20GHz (e.g., falling within Band 3), and the terminal device's current operating frequency band combination is Band 1 + Band 2 + Band 6 + Band 7, then S202 can be: 20GHz belongs to FR1. The network device determines whether the target measurement frequency requires a measurement gap based on the first indication information and the first frequency band combination. Specifically, the frequency band combination belonging to FR1 in the terminal device's current operating frequency band combination is Band 1 + Band 2. According to the first indication information shown in Table 3, the indication for Band 3 corresponding to the frequency band combination Band 1 + Band 2 is "0", so it can be determined that no measurement gap is needed. If the target measurement frequency belongs to FR2, the determination method is similar, and will not be elaborated further here.

[0154] Optionally, if the first frequency band combination list includes a frequency band combination consisting of the first frequency band combination and the frequency band to which the target measurement frequency point belongs, the network device determines that the target measurement frequency point does not require a measurement gap. For example, if the target measurement frequency point belongs to Band 5, since the frequency band combination consisting of the first frequency band combination (Band 1 + Band 2) and Band 5 is Band 1 + Band 2 + Band 5, then taking the frequency band combination list shown in Table 3 as an example, if the first frequency band combination list includes a frequency band combination like Band 1 + Band 2 + Band 5, the network device determines that the target measurement frequency point does not require a measurement gap. If the first frequency band combination list does not include a frequency band combination consisting of the first frequency band combination and the frequency band to which the target measurement frequency point belongs, the network device determines whether the target measurement frequency point requires a measurement gap based on the first indication information. For example, if the target measurement frequency belongs to Band 3, since the band combination formed by the first band combination (Band 1 + Band 2) and Band 3 is Band 1 + Band 2 + Band 3, we can first determine whether the first band combination list includes this band combination. If it is determined that the first band combination list does not include this band combination, then according to Table 3, the indication for Band 3 corresponding to the band combination Band 1 + Band 2 is "0", thus confirming that the target measurement frequency does not require a measurement gap. In other words, if it is determined that the first band combination list does not include the band combination formed by the first band combination and the band to which the target measurement frequency belongs, the network device uses the previous method: determining whether the target measurement frequency requires a measurement gap based on the first indication information and the first band combination.

[0155] S203. When the network device determines that a measurement gap is required for the target measurement frequency point, it sends measurement gap configuration information to the terminal device.

[0156] Wherein, if the terminal device supports independent measurement gaps, the terminal device will terminate data transmission with the corresponding FR serving cell during the measurement gap, while other serving cells can continue data transmission. Optionally, the indication information that the terminal device supports independent measurement gaps can be carried in the capability information. If the terminal device supports independent measurement gaps, then for a certain target measurement frequency, the type of measurement gap is one of the measurement gap corresponding to the terminal device, the measurement gap corresponding to the first frequency range, and the measurement gap corresponding to the second frequency range. If the terminal device does not support independent measurement gaps, then for the target measurement frequency, the type of measurement gap is the measurement gap corresponding to the terminal device.

[0157] S204. The terminal equipment measures the target measurement frequency point according to the measurement gap configuration information.

[0158] Figure 4An interactive flowchart of another embodiment of the communication method provided in this application is shown below. Figure 4 As shown, the method in this embodiment may include:

[0159] S301. The terminal device sends capability information to the network device, wherein the capability information includes first capability information corresponding to a first frequency range and second capability information corresponding to a second frequency range. The first capability information and the second capability information are independent information. The first capability information includes a first frequency band list and a first frequency band combination list, and the second capability information includes a second frequency band list and a second frequency band combination list.

[0160] The first frequency band list is a list of all frequency bands within a first frequency range supported by the terminal device. The first frequency band combination list is a list of combinations of frequency bands within the first frequency range supported by the terminal device. The second frequency band list is a list of all frequency bands within a second frequency range supported by the terminal device. The second frequency band combination list is a list of combinations of frequency bands within the second frequency range supported by the terminal device.

[0161] By reporting a first frequency band combination list and a second frequency band combination list, the system indicates (or notifies) that the terminal device supports carrier aggregation by combining any frequency band combination or subset of any frequency band combination in the first frequency band combination list with any frequency band combination or subset of any frequency band combination in the second frequency band combination list. The network device can then configure carrier aggregation accordingly. Optionally, the system also includes indicating that the terminal device supports carrier aggregation by combining any frequency band combination in the first frequency band combination list with any frequency band in the second frequency band list, and vice versa. For example, if the first frequency band list includes Band 1, Band 2, and Band 3, and the first frequency band combination list includes Band 1+Band 2 and Band 1+Band 3 combinations, and the second frequency band list includes Band 6, Band 7, and Band 8, and the second frequency band combination list includes Band 6+Band 7 and Band 6+Band 8 combinations, then the terminal device supports combining any frequency band combination in the first frequency band combination list with any frequency band combination in the second frequency band combination list, i.e., Band 1+Band 2+Band 6+Band 7, Band 1+Band 2+Band 6+Band 8, Band 1+Band 3+Band 6+Band 7, and Band 1+Band 3+Band 6+Band 8. Optionally, it also supports combining any frequency band combination in the first frequency band combination list with any frequency band in the second frequency band list, i.e., Band 1+Band 2+Band 6, Band 1+Band 2+Band 7, and Band 1+Band 8. +Band2+Band8, Band1+Band3+Band6, Band1+Band3+Band7, Band1+Band3+Band8, also supports combining any band combination in the second band combination list with any band in the first band list, i.e., Band6+Band7+Band1, Band6+Band7+Band2, Band6+Band7+Band3, Band6+Band8+Band1, Band6+Band8+Band2, Band6+Band8+Band3, also supports combining any band in the first band list with any band in the second band list, i.e., Band1+Band6, Band1+Band7, Band1+Band8, Band2+Band6, Band2+Band7, Band2+Band8, Band3+Band6, Band3+Band7, Band3+Band8.According to existing technology, terminal devices need to report all supported frequency band combinations to the network. In the example above, 29 frequency band combinations need to be reported. However, based on the method of this embodiment, terminal devices do not need to report the combination of frequency bands in the first frequency range and frequency bands in the second frequency range. Terminal devices only need to report the combination of frequency bands in the first frequency range and the combination of frequency bands in the second frequency range, i.e., 4 frequency band combinations. This greatly reduces the number of frequency band combinations, thereby reducing the size of the capability information reported by the terminal device (or size), reducing signaling overhead, and also reducing the storage overhead of network devices.

[0162] S302. The network device determines the frequency band combinations supported by the terminal device based on the first frequency band combination list and the second frequency band combination list.

[0163] Specifically, the network device determines the frequency band combinations supported by the terminal device based on the first frequency band combination list and the second frequency band combination list by: the network device performing carrier aggregation based on the fact that any frequency band combination or a subset of any frequency band combination in the first frequency band combination list can be combined with any frequency band combination or a subset of any frequency band combination in the second frequency band combination list, thereby configuring carrier aggregation and determining the frequency band combinations supported by the terminal device.

[0164] Optionally, the above method further includes:

[0165] S303. The network device determines whether a measurement gap is needed for the target measurement frequency point based on the target measurement frequency point of the terminal device, the current operating frequency band combination of the terminal device, and capability information.

[0166] Specifically, if the target measurement frequency point belongs to a first frequency range, the network device determines whether the target measurement frequency point needs a measurement gap based on the first capability information and the first frequency band combination. The first frequency band combination refers to the frequency band combination that belongs to the first frequency range among the frequency band combinations currently operating on the terminal device. If the list of first frequency band combinations includes a frequency band combination consisting of the first frequency band combination and the frequency band to which the target measurement frequency point belongs, the network device determines that the target measurement frequency point does not need a measurement gap. If the list of first frequency band combinations does not include a frequency band combination consisting of the first frequency band combination and the frequency band to which the target measurement frequency point belongs, the network device determines that the target measurement frequency point needs a measurement gap.

[0167] If the target measurement frequency falls within the second frequency range, the network device determines whether a measurement gap is required based on the second capability information and the second frequency band combination. The second frequency band combination refers to the frequency band combination within the second frequency range currently operating on the terminal device. If the second frequency band combination list includes a frequency band combination consisting of the second frequency band combination and the frequency band to which the target measurement frequency belongs, the network device determines that a measurement gap is not required for the target measurement frequency. If the second frequency band combination list does not include a frequency band combination consisting of the second frequency band combination and the frequency band to which the target measurement frequency belongs, the network device determines that a measurement gap is required for the target measurement frequency.

[0168] Based on the method in this embodiment, the terminal device does not need to report separate indication information on whether a gap needs to be measured. The network can determine whether a gap needs to be measured based on the first frequency band combination list or the second frequency band combination list in the capability information reported by the terminal device, thereby reducing the size (or dimension) of the capability information reported by the terminal device, reducing signaling overhead, and also reducing the storage overhead of the network device.

[0169] Furthermore, the communication method provided in this embodiment sends capability information from a terminal device to a network device. The capability information includes first capability information corresponding to a first frequency range and second capability information corresponding to a second frequency range. The first capability information and the second capability information are independent information. The first capability information includes a first frequency band list and a first frequency band combination list, and the second capability information includes a second frequency band list and a second frequency band combination list. The network device determines whether the target measurement frequency point needs a measurement gap based on the target measurement frequency point of the terminal device, the frequency band combination currently operating of the terminal device, and the capability information. The first capability information corresponding to the first frequency range and the second capability information corresponding to the second frequency range are reported as independent information, which reduces signaling overhead and can also reduce the storage overhead of the network device.

[0170] Optionally, this application also provides a communication method. Figure 5 A flowchart of an embodiment of a communication method provided in this application is shown below. Figure 5 As shown, the method in this embodiment may include:

[0171] S401. The terminal device receives the third measurement gap configuration information from the LTE network device.

[0172] When the terminal device connects to the LTE network device, it will receive third measurement gap configuration information from the LTE network device. The third measurement gap configuration information includes measurement gap configuration (e.g., the period and / or length of the measurement gap), but does not include the measurement gap type. That is to say, the measurement gap configuration in the third measurement gap configuration information is not associated with the measurement gap type.

[0173] S402. When the terminal device receives a message from the LTE network device to add an NR cell as a serving cell or receives the measurement configuration of the NR frequency point sent by the LTE network device, delete the third measurement gap configuration information.

[0174] When the terminal device needs to measure the gap, the network device needs to reconfigure the measurement gap of the terminal device. In this case, optionally, the embodiments of this application may also include the following steps:

[0175] S403. The network device sends the fourth measurement gap configuration information to the terminal device.

[0176] The fourth measurement gap configuration information includes: measurement gap configuration and measurement gap type.

[0177] The measurement gap type is one of the following: a measurement gap corresponding to the terminal device, a measurement gap corresponding to the first frequency range, and a measurement gap corresponding to the second frequency range. The measurement gap configuration may include the period and / or length of the measurement gap.

[0178] Optionally, the network device in S403 can be the LTE network device in S401, or a 5G system or other system network device.

[0179] In one possible approach, the fourth measurement gap configuration information here could be obtained using the previously mentioned... Figures 2-4 The fourth measurement gap configuration information is determined in the manner shown in any embodiment. It is understood that the fourth measurement gap configuration information may also be determined in other ways, and the embodiments of this application do not limit this.

[0180] S404. The terminal equipment measures the target measurement frequency point according to the measurement gap configuration information.

[0181] In this embodiment, by deleting the measurement gap configured in the LTE system by the terminal device, the problem that after the terminal device receives a message to add an NR cell as a serving cell or receives the measurement configuration of an NR frequency point, it is unclear whether the measurement gap configured in LTE can be used to measure the neighboring cells of FR2.

[0182] Furthermore, when the terminal device needs to measure the gap, the network device reconfigures the measurement gap for the terminal device and indicates the type of measurement gap, thus solving the problem of how to perform measurement configuration.

[0183] Figure 6 A flowchart of an embodiment of a communication method provided in this application is shown below. Figure 6 As shown, the method in this embodiment may include:

[0184] S501. The terminal device receives fifth measurement gap configuration information from the LTE network device. The fifth measurement gap configuration information includes measurement gap configuration and measurement gap type.

[0185] S502, The terminal device measures the target measurement frequency point according to the configuration information of the fifth measurement gap.

[0186] When the terminal device connects to the LTE network device, it receives fifth measurement gap configuration information from the LTE network device. This fifth measurement gap configuration information includes measurement gap configuration (e.g., the period and / or length of the measurement gap) and the type of measurement gap. The type of measurement gap can be one of the measurement gap corresponding to the terminal device, the measurement gap corresponding to a first frequency range, or the measurement gap corresponding to a second frequency range. The measurement gap configuration specifically refers to the period and / or length of the measurement gap. When the LTE network determines that the terminal device supports NR, or in other words, supports the FR2 frequency range, the network device configures this fifth measurement gap configuration information, and this fifth measurement gap configuration information carries the type of measurement gap, thereby avoiding the ambiguity of whether the measurement gap can be used to measure neighboring cells of FR2, which would arise if the measurement gap type were not carried.

[0187] Optionally, the method in this embodiment may further include:

[0188] S503. When the terminal device receives a message from the LTE network device to add an NR cell as a serving cell or receives the measurement configuration of the NR frequency point sent by the LTE network device, it measures the target measurement frequency point according to the fifth measurement gap configuration information.

[0189] In this embodiment, the LTE network equipment further configures a measurement gap for the terminal device and indicates the type of measurement gap, so that when the terminal device receives a message to add an NR cell as a serving cell or receives a measurement configuration for an NR frequency point, the terminal device can determine whether the measurement gap can be used to measure the neighboring cells of FR2 according to the fifth measurement gap configuration information.

[0190] Optionally, this application embodiment also provides a communication method in which, when a terminal device receives a configured measurement gap in LTE, if no measurement gap type is configured, the default measurement gap type is either the measurement gap corresponding to the terminal device or the measurement gap corresponding to a first frequency range (below 24 GHz). Alternatively, the terminal device determines the measurement gap type based on capability information and measurement configuration. This solves the problem that after the terminal device receives a message adding an NR cell as a serving cell or receives a measurement configuration for an NR frequency point, the type of the configured measurement gap in LTE is not indicated, and it is unclear whether the measurement gap can be used to measure neighboring cells of FR2.

[0191] Optionally, this application also provides a communication method. Figure 7 A flowchart of an embodiment of a communication method provided in this application is shown below. Figure 7 As shown, the method in this embodiment may include:

[0192] S601. The network device sends a message to the terminal device to add or delete a serving cell.

[0193] S602. The terminal device sends the updated third indication information corresponding to the current working frequency band combination to the network device. The third indication information includes an indication of whether each frequency band supported by the terminal device corresponding to the updated current working frequency band combination needs to be measured for gaps.

[0194] S603. The network device determines whether a measurement gap is required for the target measurement frequency based on the target measurement frequency and the third indication information.

[0195] Specifically, after receiving a message about adding or deleting a serving cell, indicating a change in the serving cell, the terminal device's current operating frequency band combination changes, and the requirement for a measurement gap for the target frequency point may also change. At this point, the terminal device feeds back the updated measurement gap capability to the network device. In other words, the terminal device provides information on whether the frequency bands it supports for measurement under its current operating frequency band combination require a measurement gap. This allows the network device to determine whether a measurement gap needs to be configured when configuring measurement intervals. For example, if a terminal device has two serving cells using frequency resources belonging to Band1 and Band2 respectively, and the network device adds a new serving cell (using frequency resources belonging to Band3), then the terminal device's current operating frequency band combination becomes Band1+Band2+Band3. The terminal device will then feed back information to the network device on whether a gap is required for the frequency bands it supports for measurement under this frequency band combination (Band1+Band2+Band3). If the network deletes the serving cell of Band 2, the terminal device will now operate in Band 1+Band 3. The terminal device will then send feedback to the network device regarding whether a gap is needed for the frequency bands supported by measurements under this Band 1+Band 3 combination. This resolves the issue of how to configure measurement gaps after the terminal device's serving cell changes.

[0196] Figure 8 A flowchart of an embodiment of a communication method provided in this application is shown below. Figure 8 As shown, the method in this embodiment may include:

[0197] S701. The network device sends a message to the terminal device for adding or deleting a serving cell, or for adding or deleting a measurement frequency point.

[0198] S702. The terminal device determines whether a measurement gap is needed. If a measurement gap is not needed, it sends an indication message indicating that a measurement gap is not needed or a request message to release the measurement gap to the network device. If a measurement gap is needed, it sends a measurement gap indication message or a request message to configure the measurement gap to the network device. The indication message or request message carries the type of the required measurement gap.

[0199] Specifically, when a terminal device is configured with measurement gaps, if a serving cell or a measurement frequency point of the terminal device is deleted, the terminal device may no longer need the measurement gaps. In this case, the terminal device sends an indication message indicating that the measurement gaps are no longer needed or a request message to release the measurement gaps to the network device. When the network device receives the indication that the measurement gaps are no longer needed or the request to release the measurement configuration, it performs the corresponding processing, such as releasing the measurement configuration.

[0200] When adding a serving cell or a measurement frequency to a terminal device, the terminal device determines the required measurement gap and feeds back the required gap and its type to the network device. The gap type can be one of the following: a measurement gap corresponding to the terminal device, a measurement gap corresponding to a first frequency range, or a measurement gap corresponding to a second frequency range. After receiving the gap requirement information from the terminal device, the network device configures the corresponding type of gap for the terminal device. This solves the problem of how to configure measurement gaps after adding or deleting a serving cell or a measurement frequency, without needing to report capability information and reducing signaling overhead.

[0201] It is understood that, in the above-described method embodiments, the operations performed by the terminal device can also be implemented by components (e.g., chips, circuits) that can be used in the terminal, and the operations performed by the network device can also be implemented by components (e.g., chips, circuits) that can be used in the network device.

[0204] The receiving module 12 is used to receive measurement gap configuration information determined based on capability information, wherein the measurement gap configuration information is information used to configure the measurement gap.

[0205] The measurement module 13 is used to perform measurements based on the measurement gap configuration information.

[0206] Optionally, the measurement module 13 is configured to: when the measurement gap type is a measurement gap corresponding to a first frequency range, stop communication in the serving cell of the first frequency range within the measurement gap and measure neighboring cells of the first frequency range within the measurement gap; or, when the measurement gap type is a measurement gap corresponding to a second frequency range, stop communication in the serving cell of the second frequency range within the measurement gap and measure neighboring cells of the second frequency range within the measurement gap; or, when the measurement gap type is a measurement gap corresponding to a terminal device, stop communication in all serving cells within the measurement gap and measure neighboring cells of the first and second frequency ranges within the measurement gap.
