Description

Multi-component carrier configuration methods, electronic devices and storage media Technical Field

[0001] This application relates to the field of wireless communication technology, such as a multi-component carrier configuration method, electronic device, and storage medium. Background Technology

[0002] For 5G and future evolution technologies such as 5G-A and 6G terminals, multiple frequency band combinations are supported. Each frequency band combination can include two or more non-contiguous component carriers to improve data rates, spectrum utilization, and enhance user experience. Traditional terminals, due to hardware limitations, generally use one radio frequency receiving link to receive one component carrier. However, the number of radio frequency receiving links supported by a terminal is limited, which restricts the number of component carriers that can be supported.

[0003] However, with the improvement of terminal device capabilities, a single RF link in a terminal can support the simultaneous processing of two or more component carriers in a frequency band combination. For example, a receiving RF link can simultaneously receive and process two or more component carriers. Terminals support shared RF link capabilities, but currently there is no mechanism for terminals to report these capabilities to the network. Even if a terminal possesses shared RF link capabilities and reports them to the network, if the interference signal received under a single RF receiving link is too large, it will lead to a decrease in the performance of each component carrier received when two or more component carriers are simultaneously received on that RF link, thus reducing the overall network performance. In this case, the network needs to reconfigure the component carriers of the frequency band combination supported by the terminal. However, the current network cannot know the different capabilities of the terminal in processing non-contiguous component carriers under a frequency band combination, thus preventing the network from correctly configuring the multi-component carrier capabilities in the frequency band combination supported by the terminal. How to enable the network to know the different capabilities in processing non-contiguous component carriers under a frequency band combination, and thus correctly configure the multi-component carrier capabilities in the frequency band combination supported by the terminal, has become an urgent problem to be solved.

[0061] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application.

[0062] In the following description, the use of suffixes such as “module,” “part,” or “unit” to denote elements is solely for the purpose of illustration in this application and has no particular meaning in itself. Therefore, “module,” “part,” or “unit” may be used interchangeably.

[0063] In this embodiment of the application, after the terminal hardware capability is improved, a radio frequency link can support two or more non-contiguous component carriers under a frequency band combination. For example, when a receiving radio frequency link can support two or more non-contiguous downlink component carriers under a frequency band combination, how can the network more accurately obtain the terminal's ability to support component carriers, so as to correctly configure the multi-component carrier capability in the frequency band combination supported by the terminal, thereby improving the overall network performance.

[0064] Referring to Figures 1-4, the information transmission direction and content of the first and second nodes in the network during component carrier configuration are illustrated. In this network, the first node may include various transmitting devices such as user equipment (UE), relay nodes (Relay nodes) performing relay functions, and transmitting points. The second node may include various transmitting devices such as a communication network including a base station (gNB), relay nodes (Relay nodes) performing relay functions, and receiving points. In 5G NR (New Radio) and subsequent 5G-A and 6G standards, component carrier (CC) is a concept used to support carrier aggregation (CA) or dual connectivity technology. Carrier aggregation includes intra-band contiguous CA, intra-band non-contiguous CA, and inter-band non-contiguous CA. Dual-link operating frequency bands can be the same type of wireless access technology frequency bands, such as both being 5G NR frequency bands or both being 6G frequency bands, or they can be different types of wireless access technology frequency bands, such as a combination of 5G NR frequency band, 4G E-UTRA frequency band, and 6G frequency band.

[0065] Carrier aggregation, or dual-link, allows devices to use multiple component carriers simultaneously for data transmission, thereby improving the overall system bandwidth and throughput. Component carriers are the basic unit of this multi-carrier operation. Each component carrier can be considered an independent carrier frequency with its own center frequency and bandwidth. In 5G, 5G-A, and future 6G, a user equipment (UE) can connect to one or more component carriers simultaneously, with each component carrier carrying either downlink or uplink signals / channels. Thus, if a UE connects to N component carriers, it can theoretically achieve N times the maximum data rate of a single carrier.

[0066] Figure 5 is a flowchart of a multi-component carrier configuration method provided in an embodiment of this application. This embodiment is applicable to component carrier configuration scenarios. The method can be executed by a multi-component carrier configuration device. As shown in Figure 5, the method provided in this embodiment includes:

[0067] In 110, the first node reports the first capability information to the second node, and the first capability information includes at least frequency band combination capability information.

[0068] The first capability information may include at least frequency band combination capability information. The frequency band combination capability information may indicate the frequency band combination capability supported by the first node. The frequency band combination capability information may be information on the combination method of multi-component carriers supported by the first node. The frequency band combination capability information may include the working frequency band of the frequency band combination of multi-component carriers supported by the first node, carrier aggregation type, dual link type, number of uplink and downlink component carriers, subcarrier spacing of each component carrier, supported bandwidth combination set of each component carrier, maximum bandwidth of component carriers, minimum bandwidth of component carriers, shared radio frequency link capability, maximum frequency domain span capability, and the capability to support component carrier sets within the maximum frequency domain span, etc.

[0069] In this embodiment of the application, the first node can upload first capability information, including frequency band combination capability, to the second node, so that the second node can obtain the first node's support for multi-component carriers.

[0070] In step 120, the first node obtains the component carrier configured by the second node based on the frequency band combination capability information.

[0071] In this embodiment of the application, the second node can allocate component carrier resources to the second node according to the frequency band combination capability information in the first capability information, and the first node can communicate according to the configured component carrier resources.

[0072] In this embodiment, the first node reports first capability information, including frequency band combination capability information, to the second node. The first node can obtain the component carriers configured by the second node according to the frequency band combination capability information. In this embodiment, the component carriers can be reasonably configured through the frequency band combination capability information of the first node, reducing interference signals within the component carrier interval, improving the communication quality on each component carrier, and enhancing the overall network performance.

[0073] For example, based on the above-described embodiments, the frequency band combination capability information includes at least one of the following:

[0074] The operating frequency band of the frequency band combination;

[0075] Carrier aggregation type of frequency band combination;

[0076] Dual-link type of frequency band combination;

[0077] The number of uplink and downlink component carriers supported by the frequency band combination;

[0078] Subcarrier spacing of each component carrier in a frequency band combination;

[0079] The set of supported bandwidth combinations for each component carrier of a frequency band combination;

[0080] The maximum bandwidth of the component carriers supported by the frequency band combination;

[0081] The minimum bandwidth of the component carriers supported by the frequency band combination;

[0082] Shared radio frequency link capability information;

[0083] Maximum frequency domain span capability information; or

[0084] Information on the ability to support component carrier sets within the maximum frequency domain span.

[0085] In this embodiment of the application, the frequency band combination capability information uploaded by the first node to the second node may include the operating frequency band of the frequency band combination, the carrier aggregation type of the frequency band combination, the dual link type of the frequency band combination, the number of uplink and downlink component carriers supported by the frequency band combination, the subcarrier spacing of each component carrier of the frequency band combination, the supported bandwidth combination set of each component carrier of the frequency band combination, the maximum bandwidth of the component carriers supported by the frequency band combination, the minimum bandwidth of the component carriers supported by the frequency band combination, shared radio frequency link capability information, maximum frequency domain span capability information, and capability information of supporting a set of component carriers within the maximum frequency domain span. The frequency band combination can be one or more operating frequency bands where the component carriers reside; the carrier aggregation type of the frequency band combination can be an indication that multiple component carriers are located in one or more operating frequency bands; the dual link type of the frequency band combination can be an indication that multiple component carriers are located in multiple operating frequency bands, where the multiple operating frequency bands can be frequency bands of the same type of radio access technology or frequency bands of different types of radio access technologies; the shared radio frequency link capability information can include information indicating whether the first node has the capability to simultaneously process two or more non-contiguous component carriers on a single radio frequency link, where the radio frequency link includes a transmit radio frequency link or a receive radio frequency link, or a transmit radio frequency link and a receive radio frequency link. Shared transmit radio frequency link capability means that the first node has the capability to simultaneously transmit and process two or more uplink non-contiguous component carriers on a single transmit radio frequency link; shared receive radio frequency link capability means that the first node has the capability to simultaneously receive and process two or more downlink non-contiguous component carriers on a single receive radio frequency link. Maximum frequency domain span capability information can include the maximum frequency span value from the minimum frequency of the carrier with the lowest center frequency among the component carriers supported under the shared radio frequency link capability to the maximum frequency span value of the carrier with the highest center frequency.

[0086] In some application embodiments, in response to the frequency band combination capability information including the capability information to support a set of component carriers within the maximum frequency domain span, the capability information to support a set of component carriers within the maximum frequency domain span includes at least one of the following: component carrier bandwidth; number of component carriers; or component carrier number number.

[0087] In this embodiment of the application, when the frequency band combination capability information uploaded by the first node includes capability information supporting a set of component carriers within the maximum frequency domain span, the capability information supporting a set of component carriers within the maximum frequency domain span may include one or more of the following: component carrier bandwidth, number of component carriers, and component carrier number number.

[0088] In some other embodiments, the maximum frequency domain span capability information includes at least one of the following:

[0089] Frequency domain span level or maximum frequency domain span value; wherein, a frequency domain span level corresponds to a maximum frequency domain span value; the maximum frequency domain span value is the span between the minimum frequency of the carrier with the lowest center frequency among the component carriers supported under the shared radio frequency link capability and the maximum frequency of the carrier with the highest center frequency.

[0090] In this embodiment of the application, the frequency band combination capability information uploaded by the first node includes maximum frequency domain span capability information. The maximum frequency domain span capability information includes at least one of frequency domain span level or maximum frequency domain span value. The frequency domain span level may include multiple level levels, and each frequency domain span level may correspond to a maximum frequency domain span value. The maximum frequency domain span value may include the span value from the minimum frequency of the carrier with the lowest center frequency point to the maximum frequency of the carrier with the highest center frequency point among the component carriers supported under the shared radio frequency link capability.

[0091] In some application embodiments, the reporting granularity of the maximum frequency domain span capability information includes at least one of the following:

[0092] Each carrier pair;

[0093] Each frequency band;

[0094] Each frequency band combination;

[0095] Each carrier combination in each frequency band combination; or

[0096] Each frequency band in each frequency band combination.

[0097] In this embodiment of the application, the first node can report the corresponding maximum span capability information for each carrier pair, each frequency band, each frequency band combination, each carrier combination in each frequency band combination, and each frequency band in each frequency band combination.

[0098] For example, when reporting maximum span capability information, for carrier pairs, the frequency domain span level or maximum frequency domain span value for different numbers of carriers can be reported. For example, for 2 carriers, one frequency domain span level or maximum frequency domain span value can be reported. For 3 carriers, one frequency domain span level or maximum frequency domain span value for the carrier pairs corresponding to the 3 carriers can also be reported. Alternatively, for different carrier combinations in a frequency band combination, the corresponding frequency domain span level or maximum frequency domain span value can be reported. For example, if there are 3 carriers in a frequency band combination, carrier 1 / 2 can be combined with carrier 2 / 3, and different frequency domain span levels or maximum frequency domain span values ​​can be reported.

[0099] Based on the above-mentioned application embodiments, the frequency band combination capability information explicitly or implicitly indicates the shared radio frequency link capability, wherein the shared radio frequency link capability is the ability of the first node to process at least two non-contiguous component carriers simultaneously on a radio frequency link.

[0100] In the embodiments of this application, the shared radio frequency link capability can be explicitly indicated, for example by indicating the frequency band or frequency band combination supported by the terminal through bit information, or by reporting the capability information of the shared radio frequency link; it can also be implicitly indicated, for example by reporting the capability of the maximum frequency domain span.

[0101] Based on the above-described embodiments, the first node can report frequency band combination capability information via BandCombinationList, CA-BandwidthClassNR, CA-BandwidthClassEUTRA, CA-ParametersEUTRA, CA-ParametersNR, and CA-ParametersNRDC signaling. Taking the signaling reporting capability of frequency band combination information defined by the TS38.306 and TS38.331 protocols as an example, the operating frequency bands of the frequency bands in the frequency band combination information are all less than 24.25 GHz.

[0102] In one exemplary implementation, the uplink and downlink component carriers in the frequency band combination can operate in the same frequency band or different frequency bands. At least two of the uplink or downlink component carriers are non-contiguous component carriers. The number of uplink component carriers is less than or equal to the number of downlink component carriers, but the number of uplink component carriers can also be greater than the number of downlink component carriers.

[0103] Taking 5G / 5G-A NR carrier aggregation as an example, carrier aggregation of discontinuous component carriers (i.e., discontinuous carrier aggregation) is bounded by the nominal channel spacing defined in TS38.101-1, where the nominal channel spacing is defined as:

[0104] NR operating frequency band for 100kHz channel raster:

[0105] NR operating frequency bands other than the 100kHz channel raster:

[0106] Among them, BW channel Indicates channel bandwidth, GB channel This represents the minimum protected bandwidth of the channel bandwidth, and n represents the maximum value of the bandwidth subcarrier spacing configuration supported in the channel bandwidth of the operating frequency band.

[0107] When the channel spacing of the center frequency bands of two component carriers is greater than the nominal channel spacing mentioned above, it is considered discontinuous carrier aggregation. Discontinuous carrier aggregation includes the following scenarios:

[0108] 1. Co-band discontinuous carrier aggregation.

[0109] Referring to Figure 6, the channel spacing of CC1 and CC2 is greater than the nominal channel spacing. CC1 and CC2 are discontinuous component carriers in discontinuous carrier aggregation. Figure 6 only illustrates the case with two component carriers; the case with more than two component carriers is similar.

[0110] Referring to Figure 7, the channel spacing of CC1 and CC2 is less than or equal to the nominal channel spacing, but the channel spacing of CC1 and CC3, and CC2 and CC3 is greater than the nominal channel spacing. Therefore, CC1 and CC2 are continuous component carriers in continuous carrier aggregation, and CC1 and CC3, and CC2 and CC3 are discontinuous component carriers in discontinuous carrier aggregation. Figure 7 only illustrates the case of three component carriers; the case of more than three component carriers is similar.

[0111] 2. Inter-band discontinuous carrier aggregation.

[0112] Referring to Figure 8, the channel spacing of CC1 and CC2, CC3 and CC4, and CC2 and CC3 are all greater than the nominal channel spacing. Therefore, CC1 and CC2, CC1 and CC3, CC1 and CC4, CC2 and CC3, CC2 and CC4, and CC3 and CC4 are all non-contiguous component carriers in non-contiguous carrier aggregation. Figure 8 only illustrates the case where each frequency band supports two component carriers; the case with more than two component carriers is similar.

[0113] Referring to Figure 9, the channel spacing of CC1 and CC2, and CC4 and CC5 is less than or equal to the nominal channel spacing. The channel spacing of CC1 and CC3, CC2 and CC3, CC3 and CC4, CC4 and CC6, and CC5 and CC6 are all greater than the nominal channel spacing. Therefore, CC1 and CC2, and CC4 and CC5 are continuous component carriers in discontinuous carrier aggregation. All other carriers are discontinuous component carriers in discontinuous carrier aggregation. Figure 9 only illustrates the case where each frequency band supports three component carriers; the case with more than three component carriers is similar.

[0114] Based on the above-described embodiments, the shared radio frequency link capability is described as whether the first node, under the frequency band combination capability reported by the first node, has the ability to simultaneously process two or more non-contiguous component carriers on a single radio frequency link. The radio frequency link includes a transmit radio frequency link or a receive radio frequency link, and a transmit radio frequency link and a receive radio frequency link.

[0115] In one exemplary implementation, when the radio frequency link is a shared transmit radio frequency link, the shared radio frequency link capability is that the first node has the ability to simultaneously transmit and process two or more uplink discontinuous component carriers on a single transmit radio frequency link.

[0116] In another exemplary embodiment, when the radio frequency link is a shared receive radio frequency link, the shared radio frequency link capability is that the first node has the ability to simultaneously receive and process two or more downlink discontinuous component carriers on a single receive radio frequency link.

[0117] The transmit RF link is the RF link from the baseband processing unit to the antenna port, and the receive RF link is the RF link from the antenna port to the baseband processing unit. Generally, the RF link includes, but is not limited to, RF processing, intermediate frequency (IF) processing, and auxiliary circuit modules. RF processing includes, but is not limited to, RF filters, RF duplexers, RF amplifiers, RF low-noise amplifiers, RF switches, automatic gain control, and other RF devices. IF processing includes, but is not limited to, IF filters, mixers, local oscillators, and other RF devices. Auxiliary circuit modules generally include power supply circuits, feedback circuits, automatic gain control circuits, phase-locked loop (PLL) circuits, and other RF auxiliary modules.

[0118] Based on the above application embodiments, the first node can report the capabilities of the shared transmit radio frequency link and the shared receive radio frequency link to the second node at the same time, or it can report only one of them, such as only reporting the capability of the shared receive radio frequency link.

[0119] Shared RF link capability can be explicitly indicated, for example by indicating the frequency bands or frequency band combinations supported by the terminal through bit information, or by reporting shared RF link capability information; it can also be implicitly indicated, for example by reporting the capability of the maximum frequency domain span.

[0120] For example: a terminal can explicitly report a value (1,1) using 2 bits to indicate that it has the ability to share both the transmit and receive radio frequency links within the frequency bands or combinations it supports; a terminal can explicitly report a value (1,0) using 2 bits to indicate that it has the ability to share the transmit radio frequency link within the frequency bands or combinations it supports; a terminal can explicitly report a value (0,1) using 2 bits to indicate that it has the ability to share the receive radio frequency link within the frequency bands or combinations it supports; a terminal can explicitly report a value (0,0) using 2 bits to indicate that it has neither the ability to share the receive radio frequency link nor the ability to share the receive radio frequency link within the frequency bands or combinations it supports.

[0121] For example, a terminal can also report information using 1 bit, such as explicitly reporting a value of 1, indicating that the terminal has the ability to share the receiving radio frequency link under the frequency band or combination of frequency bands supported by the terminal. In this case, the shared radio frequency link capability refers to the shared receiving radio frequency link capability.

[0122] For example, a terminal can also indicate that it has the capability to share a radio frequency link by explicitly reporting signaling information about the shared radio frequency link capability, such as reporting signaling information about the shared receiving radio frequency link capability.

[0123] For example, the terminal may implicitly indicate that it has the ability to share a radio frequency link in the frequency bands or combinations of frequency bands it supports, such as by only reporting the maximum frequency domain span.

[0124] The maximum frequency domain span is the span between the minimum frequency of the carrier with the lowest center frequency and the maximum frequency of the carrier with the highest center frequency among the component carriers supported by the shared radio frequency link.

[0125] The maximum frequency domain span capability information includes at least one of the following:

[0126] Frequency domain span level; or maximum frequency domain span value.

[0127] The granularity for reporting maximum frequency domain span capability information includes at least one of the following:

[0128] Report the maximum frequency domain span capability information for each frequency band; report the maximum frequency domain span capability information for each combination of frequency bands; or report the maximum frequency domain span capability information for each frequency band in each combination of frequency bands.

[0129] Each frequency span level corresponds to a maximum frequency span value. The maximum frequency span capability reported by different frequency bands or combinations of frequency bands can vary. For in-band and out-of-band non-contiguous frequency band combinations, the terminal reports both the frequency span level and the maximum frequency span value. The reported frequency span level and corresponding maximum frequency span value can be the same or different. Table 1 provides an example of the maximum frequency span capability information.

[0130] Table 1. Examples of Frequency Domain Span Levels

[0131] For example, the maximum frequency domain span capability information for in-band discontinuous frequency band combinations and out-of-band discontinuous frequency band combinations is shown in Tables 2 and 3, respectively:

[0132] Table 2. Examples of Frequency Domain Span Levels for Combinations of Non-Consecutive Frequency Bands in the Same Band

[0133] Table 3. Examples of Frequency Domain Span Levels for Combinations of Discontinuous Frequency Bands in Different Bands

[0134] In this embodiment of the application, the carrier method for reporting the capability information of the maximum frequency domain span includes at least one of the following: reporting the frequency domain span level value or the maximum frequency domain span value corresponding to different numbers of carriers. For example, with 2 carriers, the frequency domain span level value 1 or the maximum frequency domain span value 200MHz is reported, while with 3 carriers, the frequency domain span level value 1 or the maximum frequency domain span value 200MHz can be reported, as shown in examples (a) and (b) in Figure 10:

[0135] The reporting can also report different carrier combinations within a frequency band combination. For example, if there are 3 carriers in a frequency band combination, carrier 1 / 2 can be combined with carrier 2 / 3, and different frequency domain span level values ​​or maximum frequency domain span values ​​can be reported, as shown in examples (b), (c) and (d) in Figure 10.

[0136] In the example in Figure 10, CC1, CC2, and CC3 can be on the same frequency band within the band combination or on different frequency bands within the band combination. In Figure 10(b), there are three component carriers that satisfy the maximum frequency domain span supported under shared RF link capability: CC1, CC2, and CC3. In Figure 10(c), there are only two component carriers that satisfy the maximum frequency domain span supported under shared RF link capability: CC1 and CC2. In Figure 10(d), there are two component carriers that satisfy the maximum frequency domain span supported under shared RF link capability: CC1 and CC2, or CC2 and CC3.

[0137] Figure 11 is a flowchart of another multi-component carrier configuration method provided in an embodiment of this application. This embodiment is a refinement based on the above embodiments, describing the configuration process of filtering information. Referring to Figure 11, the method provided in this embodiment includes:

[0138] In 210, the first node obtains the configuration instructions for the filtering information transmitted by the second node.

[0139] The configuration instruction can be an instruction message issued by the second node. The instruction message can be a filtering message used by the first node to filter the first capability information. The filtering message can be used to filter the frequency band combination capability information of the first capability information. It can include the critical conditions for filtering out the frequency band combination capability information. The filtering message can include frequency domain span information, minimum inter-carrier spacing, etc. The filtering message can be indicated by Radio Resource Control (RRC) signaling.

[0140] In this embodiment of the application, the second node can transmit a configuration instruction to the first node. The configuration instruction can indicate the filtering information of the first node. The first node can filter the first capability information according to the filtering information, thereby reporting the first capability information that conforms to the filtering information to the second node.

[0141] In 220, the first node reports the first capability information that conforms to the filtering information to the second node. The first capability information includes frequency band combination capability information.

[0142] In this embodiment, the first node can filter the first capability information by configuring the filtering information configured by the configuration instruction, and transmit the first capability information with filtered symbol information to the second stage.

[0143] In step 230, the first node obtains the component carrier configured by the second node based on the frequency band combination capability information.

[0144] For example, based on the above application embodiments, the filtering information includes at least one of the following: frequency domain span information or minimum inter-carrier spacing information.

[0145] In this embodiment, the frequency domain span information can be critical information that meets the reporting requirements. For example, the UE only reports the first capability information that meets the frequency domain span information. If the maximum frequency domain span of the frequency band combination is greater than the frequency domain span requirement of the frequency domain span information, the frequency band combination is not reported. The minimum inter-carrier spacing information can be the minimum spacing information between the component carriers of the frequency band combination. The first node only reports the frequency band combination that meets the minimum spacing information. For frequency band combinations with a minimum spacing less than the minimum spacing information, no reporting is required.

[0146] In some application embodiments, the granularity of the configuration indication includes at least one of the following: each terminal; each frequency band; each combination of frequency bands; or each frequency band in each combination of frequency bands.

[0147] In one exemplary implementation, before the first node reports to the second node, the second node may instruct the first node to configure filtering information. This filtering information can be indicated via RRC signaling (e.g., reconfiguration information). The filtering information may include frequency domain span information. The second node can set the required frequency domain span information according to actual needs. In this frequency domain span setting, the maximum frequency domain span can be set to 0. When the maximum frequency domain span is 0, even if the first node reports shared RF link capability and the capability of the maximum frequency domain span, the second node will not enable the shared RF link capability reported by the first node, and the second node instructs the first node to disable the RF sharing function. When the maximum frequency domain span is not 0, assuming the maximum frequency domain span is x MHz, after receiving the frequency domain span filtering information instruction sent by the second node, the first node will only report the set of component carriers with a maximum frequency span <= x MHz.

[0148] In addition, the filtering information may also include minimum inter-carrier spacing information. The second node can set the required minimum inter-carrier spacing information according to actual needs, such as y MHz (y>0). After receiving the minimum spacing filtering information indication sent by the second node, the first node only reports the component carrier set with a minimum spacing >= y MHz. If the first node does not have a component carrier set that meets the minimum spacing >= y MHz requirement, the first node can explicitly report that it does not support a component carrier set that meets the minimum spacing >= y MHz requirement. The indication information can be a bit information value such as '0', or other values ​​such as NA. In this case, the second node does not enable the shared radio frequency link capability reported by the first node, and the second node instructs the first node to disable the radio frequency sharing function. If the first node has a component carrier set that meets the minimum spacing >= y MHz requirement, then the first node only reports the component carrier set with a minimum spacing >= y MHz requirement.

[0149] For example, the granularity of the filtering information configured by the second node for the first node may include at least one of the following:

[0150] Provide the corresponding filtering information for each terminal;

[0151] The corresponding filtering information is indicated for each frequency band;

[0152] For each frequency band combination, indicate the corresponding filtering information; or

[0153] For each frequency band in each frequency band combination, indicate the corresponding filtering information.

[0154] Figure 12 is a flowchart of another multi-component carrier configuration method provided in an embodiment of this application. This embodiment is a refinement based on the above embodiment, describing the transmission method of frequency band combination capability information included in the first capability information. Referring to Figure 12, the method provided in this embodiment includes:

[0155] In 310, the first node reports the first capability information to the second node, which includes frequency band combination capability information.

[0156] In step 320, the first node obtains the indication information sent by the second node and measures the power intensity of the interference signal within the component carrier interval in the component carrier set corresponding to the indication information.

[0157] The indication information may be information that instructs the first node to measure the interference signal within the component carrier interval in the component carrier set.

[0158] In this embodiment of the application, the second node can transmit indication information to the first node. The indication information can instruct the first node to measure the interference signal within the component carrier interval in the component carrier set and obtain the power intensity of the interference signal. The component carrier set can be indicated by the second node or determined by the first node itself.

[0159] In 330, the first node explicitly or implicitly reports to the second node whether the power intensity of the interference signal within the component carrier interval of the component carrier set meets or does not meet the preset requirements.

[0160] The preset requirements may include conditions such as power strength meeting the criteria for deactivating a cell, power strength meeting the criteria for activating radio frequency sharing capability, and conditions for the first node to report to the network. These preset requirements can be configured on the first node. The maximum power strength of the interference signal within the component carrier interval is the maximum value of the interference signal power strength measured by the first node.

[0161] In this embodiment, the first node can compare the measured power intensity with a preset requirement to determine whether the power intensity of the interfering signal within the component carrier interval of the component carrier set meets the preset requirement configured within the first node. The first node reports the result of whether the power intensity of the interfering signal meets or does not meet the preset requirement to the second node. The reporting can be implemented in an explicit or implicit manner. For example, whether the maximum power intensity of the interfering signal meets the requirement can be explicitly indicated, such as by using 1 bit information to indicate whether the maximum power intensity of the interfering signal within the component carrier interval of the frequency band or frequency band combination meets the requirement; it can also be implicitly indicated, such as by reporting the maximum power intensity as inf.

[0162] In 340, the first node obtains the component carrier configured by the second node based on the frequency band combination capability information.

[0163] In some application embodiments, power intensity includes at least one of the following: received power, received power spectral density, received power intensity indication, or energy per resource unit.

[0164] Figure 13 is a flowchart of another multi-component carrier configuration method provided in this application embodiment. This application embodiment is a refinement based on the above embodiments, describing the process of uploading the first capability information. Referring to Figure 13, the method provided in this application embodiment includes:

[0165] In 410, the first node reports the shared radio frequency link capability information, the maximum frequency domain span capability information, and the capability information of supporting component carrier sets within the maximum frequency domain span to the second node. Among them, the maximum frequency domain span capability information is the span value from the minimum frequency of the carrier with the lowest center frequency to the maximum frequency of the carrier with the highest center frequency among the component carriers supported under the shared radio frequency link capability information.

[0166] In this embodiment of the application, the first capability information reported by the first node to the second node includes shared radio frequency link capability information, maximum frequency domain span capability information, and capability information supporting a set of component carriers within the maximum frequency domain span. The maximum frequency domain span capability information is the span value from the minimum frequency of the carrier with the lowest center frequency to the maximum frequency of the carrier with the highest center frequency among the component carriers supported under the shared radio frequency link capability information.

[0167] In 420, the first node receives information from the second node requesting the measurement of the interference signal capability within the component carrier interval of the component carrier set, and measures the power intensity of the interference signal within the component carrier interval of the component carrier set.

[0168] In this embodiment, the second node can send information to the first node, which can request the first node to measure the interference signal within the component carrier interval of the component carrier set and determine the power intensity of the interference signal within the component carrier interval of the component carrier set.

[0169] In 430, the first node explicitly or implicitly reports to the second node whether the power intensity of the interference signal within the component carrier interval of the component carrier set meets or does not meet the preset requirements.

[0170] In 440, the first node obtains the component carrier configured by the second node based on the frequency band combination capability information.

[0171] In one exemplary implementation, referring to FIG14, the multi-component carrier configuration method provided in this application embodiment may include:

[0172] 1. The first node, while reporting the shared radio frequency link capability and the maximum frequency domain span supported under the shared radio frequency link capability, also reports the set of component carriers supported by the maximum frequency domain span under the frequency band combination supported by the terminal:

[0173] The set of component carriers is denoted as {CC1, CC2, ..., CCn}, consisting of n component carriers, where the center frequencies of CC1, CC2, and CCn increase sequentially, or denoted as {BW1, BW2, ..., BWn}, where BWn is the bandwidth of the corresponding carrier CCn, consisting of n component carriers.

[0174] 2: The second node requests the first node's ability to measure interference signals;

[0175] 3: When the first node receives the information from the second node requesting the measurement of the interference signal capability, the first node measures the power intensity of the interference signal within the component carrier interval in the component carrier set and reports whether the power intensity of the interference signal meets the preset requirements.

[0176] The first node measures the power intensity of the interference signal within the component carrier interval in the component carrier set to obtain the power intensity of the interference signal within the interval. The power intensity information includes at least one of the following:

[0177] Received power;

[0178] Received power spectral density (PSD);

[0179] Received Signal Strength Indicator (RSSI); or

[0180] Energy Per Resource Element (EPRE).

[0181] The component carrier spacing is defined as the span between the maximum frequency of the lowest center frequency carrier and the minimum frequency of the highest center frequency carrier among two adjacent component carriers within the maximum frequency domain span. The component carrier spacing required to measure the power intensity of the interference signal should be greater than or equal to 2·|FInterferer(offset),j|-BWChannel(j), where the parameter FInterferer(offset),j is the frequency offset of the adjacent component carrier j within the interference signal distance interval, defined in the TS38.101-1 protocol, and BWChannel(j) is the bandwidth of component carrier j.

[0182] If the maximum power intensity of the interference signal measured by the first node exceeds the maximum threshold Y, where Y ≤ -20dBm, then:

[0183] 1: If the component carrier interval is greater than or equal to 2·|FInterferer(offset),j|-BWChannel(j), then the power intensity of the interference signal within the component carrier interval in the component carrier set reported by the first node does not meet the preset requirements;

[0184] 2: If the component carrier interval is less than 2·|FInterferer(offset),j|-BWChannel(j), then the power intensity of the interference signal within the component carrier interval in the component carrier set reported by the first node meets the preset requirements;

[0185] If the power intensity of the interference signal measured by the first node is less than the maximum threshold Y, Y≤-20dBm, then the first node reports that the power intensity of the interference signal within the component carrier interval of the set meets the preset requirements.

[0186] Whether the maximum power intensity of the interference signal meets the requirements can be explicitly indicated, for example, by using 1 bit information to indicate whether the maximum power intensity of the interference signal within the component carrier interval under the frequency band or frequency band combination supported by the terminal meets the requirements. For example, in the 1 bit information, '1' indicates that the maximum power intensity of the interference signal meets the preset requirements, and '0' indicates that the maximum power intensity of the interference signal does not meet the preset requirements. Alternatively, it can be implicitly indicated, for example, by reporting the maximum power intensity as inf to indicate that the maximum power intensity does not meet the preset requirements.

[0187] Figure 15 is a flowchart of another multi-component carrier configuration method provided in this application embodiment. This application embodiment is a refinement based on the above embodiments, describing the process of uploading the first capability information. Referring to Figure 15, the method provided in this application embodiment includes:

[0188] In 510, the first node reports the shared radio frequency link capability information and the maximum frequency domain span capability information to the second node. The maximum frequency domain span capability information is the span value from the minimum frequency of the carrier with the lowest center frequency to the maximum frequency of the carrier with the highest center frequency among the component carriers supported by the shared radio frequency link capability information.

[0189] In this embodiment of the application, the first capability information reported by the first node to the second node includes shared radio frequency link capability information and maximum frequency domain span capability information. The maximum frequency domain span capability information is the span value from the minimum frequency of the carrier with the lowest center frequency to the maximum frequency of the carrier with the highest center frequency among the component carriers supported by the shared radio frequency link capability information.

[0190] In 520, the first node receives a message request from the second node inquiring about the maximum frequency domain span capability information supporting the component carrier set.

[0191] In this embodiment of the application, the first node does not upload the capability information of supporting component carrier sets within the maximum frequency domain span to the first node. The second node can send a message request to the first node, which can query the first node for the capability information of supporting component carrier sets within the maximum frequency domain span.

[0192] In 530, the first node reports to the second node the capability information of supporting component carrier sets within the maximum frequency domain span.

[0193] In this embodiment of the application, when the first node receives a message request inquiring about the maximum frequency domain span capability information supporting the component carrier set, it can report the capability information supporting the component carrier set within the maximum frequency domain span to the second node.

[0194] In step 540, the first node receives information from the second node requesting the measurement of the interference signal capability within the component carrier interval of the component carrier set, and measures the power intensity of the interference signal within the component carrier interval of the component carrier set.

[0195] For example, the second node can send information to the first node, which can be used to instruct the first node to measure the interference signal capability within the component carrier interval of the component carrier set, and can obtain the power intensity of the interference signal within the component carrier interval of the component carrier set.

[0196] In 550, the first node explicitly or implicitly reports to the second node whether the power intensity of the interference signal within the component carrier interval of the component carrier set meets or does not meet the preset requirements.

[0197] In 560, the first node obtains the component carrier configured by the second node based on the frequency band combination capability information.

[0198] In one exemplary embodiment, FIG16 is an example diagram of a multi-component carrier configuration method provided by an embodiment of the present application. The multi-component carrier configuration method provided by the embodiment of the present application may include:

[0199] 1: While reporting the shared radio frequency link capability and the maximum frequency domain span supported under the shared radio frequency link capability, the first node did not report the set of component carriers supported by the maximum frequency domain span under the frequency band combination supported by the terminal.

[0200] 2: The second node trains the frequency band combination capability of the first node.

[0201] 3: After receiving the query message request from the second node, the first node, according to the instructions of the second node, reports to the second node the set of component carriers supported by the maximum frequency domain span under the frequency band combination that conforms to the instructions of the second node:

[0202] The set of component carriers is denoted as {CC1, CC2, ..., CCn}, consisting of n component carriers, where the center frequencies of CC1, CC2, and CCn increase sequentially, or denoted as {BW1, BW2, ..., BWn}, where BWn is the bandwidth of the corresponding carrier CCn, consisting of n component carriers.

[0203] 4: The second node requests the first node's ability to measure interference signals.

[0204] 5: When the first node receives the information from the second node requesting the measurement of the interference signal capability, the first node measures the power intensity of the interference signal within the component carrier interval in the component carrier set and reports whether the power intensity of the interference signal meets the preset requirements.

[0205] The first node measures the power intensity of the interference signal within the component carrier interval in the component carrier set to obtain the power intensity of the interference signal within the interval. The power intensity information includes at least one of the following:

[0206] Received power;

[0207] Received power spectral density (PSD);

[0208] Received Signal Strength Indicator (RSSI); or

[0209] Energy Per Resource Element (EPRE).

[0210] The component carrier spacing is defined as the span between the maximum frequency of the lowest center frequency carrier and the minimum frequency of the highest center frequency carrier among two adjacent component carriers within the maximum frequency domain span. The component carrier spacing required to measure the power intensity of the interference signal should be greater than or equal to 2·|FInterferer(offset),j|-BWChannel(j), where the parameter FInterferer(offset),j is the frequency offset of the adjacent component carrier j within the interference signal distance interval, defined in the TS38.101-1 protocol, and BWChannel(j) is the bandwidth of component carrier j.

[0211] If the maximum power intensity of the interference signal measured at the first node within the component carrier interval exceeds the maximum threshold Y, where Y ≤ -20 dBm, then:

[0212] 1: If the component carrier interval is greater than or equal to 2·|FInterferer(offset),j|-BWChannel(j), then the power intensity of the interference signal within the component carrier interval in the component carrier set reported by the first node does not meet the preset requirements;

[0213] 2: If the component carrier interval is less than 2·|FInterferer(offset),j|-BWChannel(j), then the power intensity of the interference signal within the component carrier interval in the component carrier set reported by the first node meets the preset requirements;

[0214] If the power intensity of the interference signal measured by the first node within the component carrier interval is less than the maximum threshold Y, where Y≤-20dBm, then the power intensity of the interference signal within the component carrier interval in the component carrier set reported by the first node meets the preset requirements.

[0215] Whether the maximum power intensity of the interference signal meets the requirements can be explicitly indicated, for example, by using 1 bit information to indicate whether the maximum power intensity of the interference signal within the component carrier interval under the frequency band or frequency band combination supported by the terminal meets the requirements. For example, in the 1 bit information, '1' indicates that the maximum power intensity of the interference signal meets the preset requirements, and '0' indicates that the maximum power intensity of the interference signal does not meet the preset requirements. Alternatively, it can be implicitly indicated, for example, by reporting the maximum power intensity as inf to indicate that the maximum power intensity does not meet the preset requirements.

[0216] Based on the above application embodiments, the maximum frequency domain span capability information includes at least one of the following: frequency domain span level or maximum frequency domain span value; wherein, a frequency domain span level corresponds to a maximum frequency domain span value.

[0217] In this embodiment of the application, the maximum frequency domain span capability information reported by the first node to the second node may include a frequency domain span level and / or a maximum frequency domain span value, wherein each frequency domain span level may correspond to a maximum frequency domain span value.

[0218] In one embodiment, based on the above-described embodiments, the reporting granularity of the maximum frequency domain span capability information includes at least one of the following:

[0219] Each carrier pair;

[0220] Each frequency band;

[0221] Each frequency band combination;

[0222] Each carrier combination in each frequency band combination; or

[0223] Each frequency band in each frequency band combination.

[0224] In this embodiment of the application, the first node can report the corresponding maximum span capability information for each carrier pair, each frequency band, each frequency band combination, each carrier combination in each frequency band combination, and each frequency band in each frequency band combination.

[0225] For example, when reporting maximum span capability information, for carrier pairs, the frequency domain span level or maximum frequency domain span value for different numbers of carriers can be reported. For example, two carriers can report one frequency domain span level or maximum frequency domain span value. When there are three carriers, one frequency domain span level or maximum frequency domain span value for the carrier pair corresponding to the three carriers can also be reported. Alternatively, the corresponding frequency domain span level or maximum frequency domain span value can be reported for different carrier combinations in a frequency band combination. For example, if there are three carriers in a frequency band combination, carrier 1 / 2 can be combined with carrier 2 / 3, and different frequency domain span levels or maximum frequency domain span values ​​can be reported.

[0226] In an exemplary implementation, referring to Figure 17, the first node supports intra-band non-contiguous carrier aggregation (CA). The first node reports the frequency band combination CA_nX for intra-band non-contiguous carrier aggregation, with two downlink component carriers CC1 and CC2, which are non-contiguous component carriers, and one or two uplink component carriers. The bandwidths of component carriers CC1 and CC2 are BW1 and BW2, respectively. The first node reports support for shared receive RF link capability and a maximum supported frequency domain span level of 1, corresponding to a maximum frequency domain span of X1 MHz. Assuming X1 = 100 MHz, the set of component carriers supported by the maximum frequency domain span is {CC1, CC2}, or denoted as {BW1, BW2}.

[0227] In this embodiment of the application, multi-component carrier configuration is performed as shown in Figure 14. The first node simultaneously reports the set of component carriers supported by the maximum frequency domain span as {CC1, CC2}, or denoted as {BW1, BW2}. In this embodiment of the application, multi-component carrier configuration is performed as shown in Figure 16. Under the instruction of the query information from the second node, the first node reports the set of component carriers supported by the maximum frequency domain span as {CC1, CC2}, or denoted as {BW1, BW2}.

[0228] In this embodiment of the application, the first node measures the maximum power intensity of the interference signal within the component carrier {CC1, CC2} interval as YdBm:

[0229] 1: If Y > -20dBm, then:

[0230] (1) If the component carrier interval is ≥ |FInterferer(offset),1|+|FInterferer(offset),2|-0.5*(BW1+BW2), the power intensity of the interference signal within the component carrier interval in the component carrier set reported by the first node does not meet the preset requirements;

[0231] (2) If the component carrier interval <|FInterferer(offset),1|+|FInterferer(offset),2|-0.5*(BW1+BW2), the power intensity of the interference signal within the component carrier interval in the component carrier set reported by the first node meets the preset requirements;

[0232] 2: If YdBm≤-20dBm, then the power intensity of the interference signal within the component carrier interval in the component carrier set reported by the first node meets the preset requirements;

[0233] The first node informs the second node whether the power intensity of the interference signal within the component carrier interval of the component carrier set {CC1, CC2} or {BW1, BW2} meets the preset requirements.

[0234] In another exemplary implementation, referring to Figure 18, the first node supports co-band non-contiguous carrier aggregation. The first node reports the frequency band combination CA_nX for co-band non-contiguous carrier aggregation, with m downlink component carriers (m≥3) and one or two uplink component carriers. Taking m=3 as an example, the same logic applies to other cases where m>3.

[0235] In Figure 18, there are three downlink component carriers: CC1, CC2 and CC3. CC1, CC2 and CC3 are three non-contiguous component carriers, and the bandwidths of component carriers CC1, CC2 and CC3 are BW1, BW2 and BW3, respectively.

[0236] The first node reports support for a shared receive RF link and a maximum supported frequency domain span level of 2, corresponding to a maximum frequency domain span of X2MHz, assumed to be X2 = 200MHz. The set of component carriers supported by the maximum frequency domain span is {CC1, CC2, CC3}, or denoted as {BW1, BW2, BW3}.

[0237] The co-band non-contiguous carrier aggregation shown in Figure 18 is configured with multi-component carriers as shown in Figure 14. The first node simultaneously reports the set of component carriers supported by the maximum frequency domain span as {CC1, CC2, CC3}, or denoted as {BW1, BW2, BW3}. The multi-component carrier configuration is also performed as shown in Figure 16. Under the instruction of the query information from the second node, the first node reports the set of component carriers supported by the maximum frequency domain span as {CC1, CC2, CC3}, or denoted as {BW1, BW2, BW3}.

[0238] The first node measures the maximum power intensity of the interference signal within the component carrier intervals {CC1, CC2} and {CC2, CC3}, which are Y1 dBm and Y2 dBm, respectively:

[0239] 1: If Y1 > -20dBm and Y2 ≤ -20dBm, then:

[0240] (1) If the component carrier interval 1≥|FInterferer(offset),1|+|FInterferer(offset),2|-0.5*(BW1+BW2), the power intensity of the interference signal in the component carrier interval of the component carrier set reported by the first node does not meet the preset requirements;

[0241] (2) If the component carrier interval 1 < |FInterferer(offset), 1| + |FInterferer(offset), 2| - 0.5*(BW1 + BW2), the power intensity of the interference signal within the component carrier interval in the component carrier set reported by the first node meets the preset requirements;

[0242] 2: If Y1≤-20dBm and Y2>-20dBm, then:

[0243] (1) If the component carrier interval 2≥|FInterferer(offset),2|+|FInterferer(offset),3|-0.5*(BW2+BW3), the power intensity of the interference signal in the component carrier interval of the component carrier set reported by the first node does not meet the preset requirements;

[0244] (2) If the component carrier interval 2 < |FInterferer(offset), 2| + |FInterferer(offset), 3| - 0.5*(BW2 + BW3), the power intensity of the interference signal within the component carrier interval in the component carrier set reported by the first node meets the preset requirements;

[0245] 3: If Y1≤-20dBm and Y2≤-20dBm, then the power intensity of the interference signal within the component carrier interval in the component carrier set reported by the first node meets the preset requirements.

[0246] The first node informs the second node whether the power intensity of the interference signal within the component carrier interval of the component carrier set {CC1, CC2, CC3} or {BW1, BW2, BW3} meets the requirements.

[0247] Referring to Figures 19 and 20, there are three downlink component carriers: CC1, CC2, and CC3. These three component carriers are not consecutive, and their bandwidths are BW1, BW2, and BW3, respectively. The first node reports support for a shared receive RF link and a maximum supported frequency domain span level of 1, corresponding to a maximum frequency domain span of X1 MHz. Assume X1 = 100 MHz.

[0248] In Figure 19, the component carrier set supported by the maximum frequency domain span is {CC1, CC2}, or denoted as {BW1, BW2}. As shown in Figure 14, the first node simultaneously reports the component carrier set supported by the maximum frequency domain span as {CC1, CC2}, or denoted as {BW1, BW2}. As shown in Figure 16, under the instruction of the second node's query information, the first node reports the component carrier set supported by the maximum frequency domain span as {CC1, CC2}, or denoted as {BW1, BW2}. The first node does not need to report the component carrier sets as {CC1, CC3} and {CC2, CC3}, or denoted as {BW1, BW3} and {BW2, BW3} respectively.

[0249] The first node measures the maximum power intensity of the interference signal within the component carrier interval {CC1, CC2} as YdBm, similar to the situation in Figure 12, and so on. The first node informs the second node whether the power intensity of the interference signal within the component carrier interval in the component carrier set {CC1, CC2} or {BW1, BW2} meets the preset requirements.

[0250] In Figure 20, both the maximum frequency span 1 and the maximum frequency span 2 satisfy the condition that the maximum frequency span level is 1, and the component carrier set supported by the maximum frequency span is {CC1, CC2} or {CC2, CC3}, or respectively denoted as {BW1, BW2} or {BW2, BW3}. As shown in Figure 14, the first node reports the component carrier set supported by the maximum frequency span as {CC1, CC2} or {CC2, CC3}, or respectively denoted as {BW1, BW2} or {BW2, BW3}; as shown in Figure 16, under the instruction of the second node's query information, the first node reports the component carrier set supported by the maximum frequency span as {CC1, CC2} or {CC2, CC3}, or respectively denoted as {BW1, BW2} or {BW2, BW3}. The first node then reports the component carrier set {CC1, CC2} or {CC2, CC3}.

[0251] If the first node reports that the component carrier set supported by the maximum frequency domain span is {CC1, CC2} or {BW1, BW2}, then the maximum power intensity of the interference signal measured by the first node within the component carrier interval {CC1, CC2} is Y1 dBm, respectively; similar to the case in Figure 19, and so on. The first node informs the second node whether the power intensity of the interference signal within the component carrier interval in the component carrier set {CC1, CC2} or {BW1, BW2} meets the preset requirements.

[0252] If the first node reports that the component carrier set supported by the maximum frequency domain span is {CC2, CC3} or {BW2, BW3}, then the maximum power intensity of the interference signal measured by the first node within the component carrier interval {CC2, CC3} is Y2 dBm, respectively; similar to the case in Figure 19, and so on. The first node informs the second node whether the power intensity of the interference signal within the component carrier interval in the component carrier set {CC2, CC3} or {BW2, BW3} meets the preset requirements.

[0253] In Figure 21, there are three downlink component carriers: CC1, CC2, and CC3. CC1 and CC2 are two consecutive component carriers, while CC1 / CC2 and CC3 are non-consecutive component carriers. The aggregate bandwidth of the consecutive component carriers CC1 and CC2 is CABW1, and the bandwidth of CC3 is BW3. The aggregate bandwidth CABW1 is calculated according to the aggregation bandwidth formula given in the TS38.101-1 protocol. The first node reports support for shared receive RF link capability and a maximum supported frequency domain span level of 1, corresponding to a maximum frequency domain span of X1MHz, assumed to be X1 = 100MHz. The set of component carriers supported by the maximum frequency domain span is {CC1, CC2, CC3}, or denoted as {BW1, BW2, BW3}.

[0256] 1: If Y > -20dBm, then:

[0257] (1) If the component carrier interval is ≥ |FInterferer(offset),1|+|FInterferer(offset),2|-0.5*(CABW1+BW2), the power intensity of the interference signal in the component carrier interval of the component carrier set reported by the first node does not meet the preset requirements;

[0264] (1) If the component carrier interval is ≥ |FInterferer(offset),1|+|FInterferer(offset),2|-0.5*(BW1+BW2), the power intensity of the interference signal within the component carrier interval in the component carrier set reported by the first node does not meet the preset requirements;

[0265] (2) If the component carrier interval <|FInterferer(offset),1|+|FInterferer(offset),2|-0.5*(BW1+BW2), the power intensity of the interference signal within the component carrier interval in the component carrier set reported by the first node meets the preset requirements;

[0267] The first node informs the second node whether the power intensity of the interference signal within the component carrier interval of the component carrier set {CC1, CC2} or {BW1, BW2} meets the preset requirements.

[0268] In one exemplary implementation, the first node reports the frequency band combination CA_nX-nY for inter-band discontinuous carrier aggregation, with m downlink component carriers (m≥3). On band nX and band nY, the number of downlink component carriers is greater than 1 for each band. Taking m=3 as an example, the same logic applies to other cases where m>3.

[0269] In Figure 23, band nX has two downlink component carriers, CC1 and CC2, and band nY has one downlink component carrier, CC3. CC1, CC2, and CC3 are three non-contiguous component carriers, with bandwidths of BW1, BW2, and BW3, respectively. The first node reports support for a shared receive RF link and a maximum supported frequency domain span level of 2, corresponding to a maximum frequency domain span of X2 MHz (assuming X2 = 200 MHz). The set of component carriers supported by the maximum frequency domain span is {CC1, CC2, CC3}, or denoted as {BW1, BW2, BW3}.

[0272] 1: If Y1 > -20dBm and Y2 ≤ -20dBm, then:

[0274] (2) If the component carrier interval 1 < |FInterferer(offset), 1| + |FInterferer(offset), 2| - 0.5*(BW1 + BW2), the power intensity of the interference signal within the component carrier interval in the component carrier set reported by the first node meets the preset requirements;

[0275] 2: If Y1≤-20dBm and Y2>-20dBm, then:

[0276] (1) If the component carrier interval 2≥|FInterferer(offset),2|+|FInterferer(offset),3|-0.5*(BW2+BW3), the power intensity of the interference signal in the component carrier interval of the component carrier set reported by the first node does not meet the preset requirements;

[0277] (2) If the component carrier interval 2 < |FInterferer(offset), 2| + |FInterferer(offset), 3| - 0.5*(BW2 + BW3), the power intensity of the interference signal within the component carrier interval in the component carrier set reported by the first node meets the preset requirements;

[0278] 3: If Y1≤-20dBm and Y2≤-20dBm, then Y>-20dBm, and the power intensity of the interference signal within the component carrier interval in the component carrier set reported by the first node meets the preset requirements.

[0279] The first node informs the second node whether the power intensity of the interference signal within the component carrier interval of the component carrier set {CC1, CC2, CC3} or {BW1, BW2, BW3} meets the preset requirements.

[0280] Referring to Figures 24 and 25, band nX has two downlink component carriers, CC1 and CC2, and band nY has one downlink component carrier, CC3. CC1, CC2, and CC3 are three non-contiguous component carriers, with bandwidths of BW1, BW2, and BW3, respectively. The first node reports support for a shared receive RF link and supports maximum frequency domain span levels 1 and 2, corresponding to maximum frequency domain spans of X1 MHz and X2 MHz, respectively. Assume X1 = 100 MHz and X2 = 200 MHz.

[0281] In Figure 24, the component carrier set supported by the maximum frequency domain span is {CC1, CC2}, or denoted as {BW1, BW2}. As shown in Figure 14, the first node simultaneously reports the component carrier set supported by the maximum frequency domain span as {CC1, CC2}, or denoted as {BW1, BW2}. As shown in Figure 16, under the instruction of the second node's query information, the first node reports the component carrier set supported by the maximum frequency domain span as {CC1, CC2}, or denoted as {BW1, BW2}. The first node does not need to report the component carrier sets as {CC1, CC3} and {CC2, CC3}, or denoted as {BW1, BW3} and {BW2, BW3} respectively.

[0282] The first node measures the maximum power intensity of the interference signal within the component carrier interval {CC1, CC2} on band nX as Y dBm, similar to the situation in Figure 19, and so on. The first node informs the second node whether the power intensity of the interference signal within the component carrier interval in the component carrier set {CC1, CC2} or {BW1, BW2} meets the preset requirements.

[0283] In Figure 25, both the maximum frequency span 1 and the maximum frequency span 2 satisfy the condition that the maximum frequency span level is 1, and the component carrier set supported by the maximum frequency span is {CC1, CC2} or {CC2, CC3}, or respectively denoted as {BW1, BW2} or {BW2, BW3}. Following the method shown in Figure 14, the first node reports the component carrier set supported by the maximum frequency span as {CC1, CC2} or {CC2, CC3}, or respectively denoted as {BW1, BW2} or {BW2, BW3}; following the method shown in Figure 16, the first node, under the instruction of the second node's query information, reports the component carrier set supported by the maximum frequency span as {CC1, CC2} or {CC2, CC3}, or respectively denoted as {BW1, BW2} or {BW2, BW3}. The first node then reports the component carrier set {CC1, CC2} or {CC2, CC3}.

[0284] If the first node reports that the component carrier set supported by the maximum frequency domain span is {CC1, CC2} or {BW1, BW2}, then the maximum power intensity of the interference signal measured by the first node within the component carrier interval {CC1, CC2} is Y1 dBm, respectively; similar to the case in Figure 19, and so on. The first node informs the second node whether the power intensity of the interference signal within the component carrier interval in the component carrier set {CC1, CC2} or {BW1, BW2} meets the preset requirements.

[0285] If the first node reports that the component carrier set supported by the maximum frequency domain span is {CC2, CC3} or {BW2, BW3}, then the maximum power intensity of the interference signal measured by the first node within the component carrier interval {CC2, CC3} is Y2 dBm, respectively; similar to the case in Figure 22, and so on. The first node informs the second node whether the power intensity of the interference signal within the component carrier interval in the component carrier set {CC2, CC3} or {BW2, BW3} meets the requirements.

[0286] In Figure 26, band nX has two downlink component carriers CC1 and CC2, and band nY has one downlink component carrier CC3. CC1 and CC2 are two consecutive component carriers, while CC1 / CC2 and CC3 are non-consecutive component carriers. The aggregate bandwidth of the consecutive component carriers CC1 and CC2 is CABW1, and the bandwidth of CC3 is BW3. The aggregate bandwidth CABW1 is calculated according to the aggregate bandwidth formula given in the TS38.101-1 protocol. The first node reports support for shared receive RF link capability and a maximum supported frequency domain span level of 2, corresponding to a maximum frequency domain span of X2 MHz, assumed to be X2 = 200MHz. The set of component carriers supported by the maximum frequency domain span is {CC1, CC2, CC3}, or denoted as {BW1, BW2, BW3}.

[0287] In Figure 26, as shown in Figure 14, the first node simultaneously reports the set of component carriers supported by the maximum frequency domain span as {CC1, CC2, CC3}, or denoted as {BW1, BW2, BW3}; as shown in Figure 16, the first node, under the instruction of the query information from the second node, reports the set of component carriers supported by the maximum frequency domain span as {CC1, CC2, CC3}, or denoted as {BW1, BW2, BW3}.

[0288] The maximum power intensity of the interference signal measured by the first node within the component carrier {CC2, CC3} interval is Y dBm:

[0289] 1: If Y > -20dBm, then:

[0290] (1) If the component carrier interval is ≥ |FInterferer(offset),1|+|FInterferer(offset),2|-0.5*(CABW1+BW2), the power intensity of the interference signal in the component carrier interval of the component carrier set reported by the first node does not meet the preset requirements;

[0291] (2) If the component carrier interval <|FInterferer(offset),1|+|FInterferer(offset),2|-0.5*(CABW1+BW2), the power intensity of the interference signal within the component carrier interval in the component carrier set reported by the first node meets the preset requirements;

[0293] The first node informs the second node whether the power intensity of the interference signal within the component carrier interval of the component carrier set {CC1, CC2, CC3} or {BW1, BW2, BW3} meets the preset requirements.

[0294] In the above embodiments, the values ​​of the carrier aggregation band combinations, the number of downlink component carriers, and the maximum frequency domain span supported by the shared receive RF link are given only for the convenience of the method in this application and do not limit the numerical range of the application. For example, the method of including only downlink component carriers in downlink carrier aggregation in the above embodiments is also applicable to the values ​​of uplink component carriers in uplink carrier aggregation and the maximum frequency domain span supported by the shared transmit RF link; as another example, the method of carrier aggregation band combinations in the above embodiments is also applicable to dual-link band combinations. In actual application or deployment, the terminal can report only the carrier aggregation band combination, or only the dual-link band combination, or report both the carrier aggregation band combination and the dual-link band combination simultaneously; as another example, the above embodiments only give the number of component carriers of one band as 3, while in actual deployment, the number of component carriers of one band can be 4 or other larger values; as another example, in some of the above embodiments, the number of bands is 2, while in actual application or deployment, the number of bands in the band combinations supported by the terminal and the network can be 3 or other larger values ​​greater than 3.

[0295] In some of the above embodiments, a maximum frequency domain span level 1 and level 2 supported by a radio frequency link and corresponding maximum frequency domain span values ​​such as 100MHz and 200MHz are given. However, in actual device implementation or deployment, the terminal can report other levels and corresponding maximum frequency domain span values. In addition, level 1, level 2 and corresponding maximum frequency domain span values ​​can also be other values ​​besides 100MHz and 200MHz. The frequency domain span and corresponding maximum frequency domain span values ​​in the examples do not limit the numerical range of this application.

[0327] Based on the above-described embodiments, it further includes: a configuration instruction for the second node to transmit filtering information to the first node.

[0328] In this embodiment of the application, the second node can transmit a configuration instruction to the first node. The configuration instruction can instruct the first node to configure the filtering information, which can be used to filter the first capability information that the first node uses to upload.

[0329] In some application embodiments, the second node obtains the first capability information reported by the first node, including:

[0340] Figure 28 is a flowchart of another multi-component carrier configuration method provided in an embodiment of this application. This embodiment is a refinement based on the above embodiments. Referring to Figure 28, the method provided in this embodiment includes:

[0341] In 710, the second node receives the shared radio frequency link capability information, the maximum frequency domain span capability information, and the capability information of supporting component carrier sets within the maximum frequency domain span reported by the first node. Among them, the maximum frequency domain span capability information is the span value from the minimum frequency of the carrier with the lowest center frequency to the maximum frequency of the carrier with the highest center frequency among the component carriers supported under the shared radio frequency link capability information.

[0342] In this embodiment of the application, the second node can receive information reported by the first node. The information may include shared radio frequency link capability information, maximum frequency domain span capability information, and capability information to support a set of component carriers within the maximum frequency domain span. It is understood that the reported information may indicate the first node's capability to support multiple component carriers.

[0343] In 720, the second node sends information to the first node requesting information on the ability to measure interference signals within the component carrier intervals of the component carrier set.

[0344] For example, the second node can send information to the first node requesting the first node to measure the interference signal capability within the component carrier interval of the component carrier set, which can determine the signal strength or signal power of the interference signal.

[0345] In 730, the power intensity of the interference signal within the component carrier interval of the component carrier set reported by the first node to the second node meets or does not meet the preset requirements.

[0346] In this embodiment, the second node can obtain whether the power intensity of the interference signal within the component carrier interval of the component carrier set measured by the first node meets or does not meet a preset requirement, and the preset requirement can be pre-configured in the first node.

[0347] In 740, the second node configures the component carrier of the first node according to the frequency band combination capability information and communicates with the first node based on the component carrier.

[0348] Figure 29 is a flowchart of another multi-component carrier configuration method provided in an embodiment of this application. This embodiment is a refinement based on the above embodiment. Referring to Figure 29, the method provided in this embodiment includes:

[0349] In 810, the second node receives the shared radio frequency link capability information and the maximum frequency domain span capability information reported by the first node. The maximum frequency domain span capability information is the span value from the minimum frequency of the carrier with the lowest center frequency to the maximum frequency of the carrier with the highest center frequency among the component carriers supported by the shared radio frequency link capability information.

[0350] In this embodiment of the application, the first capability information reported by the first node to the second node includes shared radio frequency link capability information and maximum frequency domain span capability information. The maximum frequency domain span capability information is the span value from the minimum frequency of the carrier with the lowest center frequency to the maximum frequency of the carrier with the highest center frequency among the component carriers supported by the shared radio frequency link capability information.

[0351] In 820, the second node sends a message request to the first node to inquire about the maximum frequency domain span capability information supporting the component carrier set.

[0352] In this embodiment of the application, the second node sends a message request to the first node to inquire about the maximum frequency domain span capability information supporting the component carrier set. The first node can report the capability information supporting the component carrier set within the maximum frequency domain span.

[0353] In 830, the second node receives information from the first node regarding its ability to support a set of component carriers within the maximum frequency domain span.

[0354] In this embodiment of the application, the first node can report the capability information of supporting component carrier sets within the maximum frequency domain span to the second node, and the second node can receive the capability information of supporting component carrier sets within the maximum frequency domain span.

[0355] In 840, the second node sends information to the first node requesting information on the ability to measure interference signals within the component carrier intervals of the component carrier set.

[0356] For example, the second node can send information to the first node requesting the first node to measure the interference signal capability within the component carrier interval of the component carrier set, which can determine the signal strength or signal power of the interference signal.

[0357] In 850, the power intensity of the interference signal within the component carrier interval of the component carrier set reported by the first node to the second node meets or does not meet the preset requirements.

[0358] In this embodiment, the second node can obtain whether the power intensity of the interference signal within the component carrier interval of the component carrier set measured by the first node meets or does not meet a preset requirement, and the preset requirement can be pre-configured in the first node.

[0359] In 860, the second node configures the component carrier of the first node according to the frequency band combination capability information and communicates with the first node based on the component carrier.

[0360] In some embodiments of the application, the maximum frequency domain span capability information includes at least one of the following:

[0361] Frequency domain span level or maximum frequency domain span value;

[0362] Each frequency domain span level corresponds to a maximum frequency domain span value.

[0363] In some embodiments of the application, the power intensity includes at least one of the following:

[0364] Received power, received power spectral density, received power intensity indication, or energy per resource unit.

[0365] In some embodiments, the second node enables or disables the shared radio frequency link capability of the first node.

[0366] In this embodiment of the application, the second node can enable or disable the shared radio frequency link capability of the first node. For example, if the power strength of the interference signal received by the second node does not meet the preset requirements, the second node can disable the shared radio frequency link capability of the first node.

[0367] In one exemplary implementation, before the first node reports to the second node, the second node may instruct the first node to configure filtering information. The filtering information can indicate frequency domain span information through RRC signaling (e.g., reconfiguration information). For example, the UE only reports the capability that meets the frequency domain span requirement. For example, it does not need to report frequency band combinations whose frequency domain span requirement is greater than the maximum frequency domain span indication.

[0368] The filtering information can include frequency domain span information. The second node can set the required frequency domain span capability according to actual needs. In the frequency domain span capability setting of the second node, the maximum frequency domain span can be set to 0. When the maximum frequency domain span is 0, even if the first node reports the shared RF link capability and the maximum frequency domain span capability, the second node will not enable the shared RF link capability reported by the first node, instructing the first node to disable the RF sharing function. When the maximum frequency domain span is not 0, assuming it is x MHz, then after receiving the frequency domain span filtering information instruction from the second node, the first node will only report the set of component carriers with a maximum frequency span <= x MHz.

[0369] Additionally, the filtering information can include minimum inter-carrier spacing information. The second node can set the required minimum inter-carrier spacing information according to actual needs, such as y MHz (y>0). After receiving the minimum spacing filtering information indication transmitted by the second node, the first node only reports the set of component carriers with a minimum spacing >= y MHz. If the first node does not have a set of component carriers with a minimum spacing >= y MHz, the first node can explicitly report that it does not support a set of component carriers with a minimum spacing >= y MHz. The indication information can be a bit value such as '0', or other values ​​such as NA. In this case, the second node does not enable the shared radio frequency link capability reported by the first node, instructing the first node to disable the radio frequency sharing function. If the first node has a set of component carriers with a minimum spacing >= y MHz, then the first node only reports the set of component carriers with a minimum spacing >= y MHz.

[0370] The granularity of the filtering information configured in the first section by the second node may include at least one of the following:

[0371] Instructions for each terminal;

[0372] Indications for each frequency band;

[0373] Indication for each frequency band combination; or

[0374] Indication for each frequency band in each frequency band combination.

[0375] In another exemplary implementation, the second node determines the query or request information to send to the first node based on the reporting method of the first node.

[0376] In the reporting method of the first node shown in Figure 14, the first node reports the shared radio frequency link capability and the maximum frequency domain span supported under the shared radio frequency link capability, as well as the set of component carriers supported by the maximum frequency domain span under the frequency band combination supported by the terminal. The second node sends a request message to the first node, which includes a request for the first node to measure the power intensity of the interference signal within the component carrier interval in the aforementioned component carrier set; the request message can be a repetitive request message with a certain time period, or it can be a repetitive request message from the second node at a custom time interval.

[0377] In the reporting method of the first node shown in Figure 16, the first node reports the shared radio frequency link capability and the maximum frequency domain span supported under the shared radio frequency link capability. The second node sends a request query to the first node, inquiring about the set of component carriers supported by the maximum frequency domain span under the frequency band combination supported by the supported terminal. After receiving the query request from the second node, the first node reports the set of component carriers supported by the maximum frequency domain span under the filtering information or the shared radio frequency link capability information. The second node sends a request message to the first node, which includes a request for the first node to measure the power intensity of the interference signal within the component carrier interval in the above-mentioned component carrier set; the request message can be a repetitive request message with a time period, or it can be a repetitive request message from the second node at a user-defined time interval.

[0378] In one embodiment, the second node request information includes a request for the first node to measure the power intensity of the interference signal within the component carrier interval in the aforementioned component carrier set; the power intensity information includes at least one of the following:

[0379] Received power;

[0380] Received power spectral density (PSD);

[0383] When the second node learns of the component carrier set supported by the maximum frequency span reported by the first node, and further learns whether the maximum power intensity of the interfering signal within the component carrier interval of that component carrier set meets the corresponding conditions, the reported information can be RRC information, such as UAI (UE assistance information). If the first node reports that the measured maximum power intensity of the interfering signal meets the corresponding conditions, the second node enables the shared radio link capability reported by the first node, instructing the first node to enable the radio sharing function, and configures the carriers of the first node according to the component carrier set supported by the maximum frequency span reported by the first node. If the first node reports that the measured maximum power intensity of the interfering signal does not meet the corresponding conditions, the second node disables the shared radio link capability reported by the first node, instructing the first node to disable the radio sharing function, and the second node activates the uplink and downlink component carriers of the component carrier set supported by the maximum frequency span reported by the first node through RRC signaling.

[0384] The phrase "the power intensity satisfies the corresponding condition" as stated above can include at least one of the following:

[0385] The power intensity meets the conditions for deactivating a certain cell.

[0386] The power intensity meets the conditions for activating radio frequency sharing; or

[0387] When the UE meets the corresponding conditions, it reports to the network.

[0388] The second node can explicitly or implicitly instruct the first node to enable / disable the radio frequency sharing function;

[0389] Explicit indication means that the first node is explicitly indicated through signaling, such as 1 bit of information, or by configuring radio frequency sharing-related parameters.

[0390] Implicit instructions are implemented by configuring capabilities / configurations that can only be achieved when the first node activates radio frequency sharing. That is, when the first node finds that the current second node's configuration is higher than the non-radio frequency sharing capability, radio frequency sharing is enabled; otherwise, radio frequency sharing is disabled.

[0391] In some embodiments, if the first node reports an indication that the measured maximum power intensity of the interference signal meets the corresponding requirements, then the second node stores the set of component carriers supported by the maximum frequency span reported by the first node and configures the first node according to this set of component carriers. That is, in Figure 17, the second node is configured as a two-carrier non-contiguous aggregation (CC1 / CC2) first node. If the first node reports an indication that the measured maximum power intensity of the interference signal does not meet the requirements, then the second node activates the component carriers of the set of component carriers supported by the maximum frequency span reported by the first node through RRC signaling. That is, in Figure 17, the second node activates CC1 or CC2, that is, the second node configures the first node in a single-carrier (CC1 or CC2) manner.

[0392] For Figure 18, if the first node reports the information indicating the maximum power intensity requirement of the measured interference signal, then the second node stores the set of component carriers supported by the maximum frequency domain span reported by the first node, and configures the first node according to this set of component carriers. In Figures 18, 19, 20 and 21, the second node is configured as the first node according to the three-carrier non-continuous aggregation (CC1 / CC2 / CC3). If the first node reports that the measured maximum power intensity of the interference signal does not meet the preset requirements, then the second node activates the component carriers of the component carrier set supported by the maximum frequency domain span reported by the first node through RRC signaling. That is, in Figure 18, the second node activates two downlink component carriers of CC1, CC2 and CC3, that is, the second node configures the first node in a single-carrier (CC1 or CC2 or CC3) manner; in Figure 19, the second node activates CC1 or CC2, that is, the second node configures the first node in a two-carrier non-contiguous aggregation configuration (CC1 / CC3 or CC2 / CC3); in Figure 20, the second node activates CC1 or CC3, that is, the second node configures the first node in a two-carrier non-contiguous aggregation configuration (CC1 / CC2 or CC2 / CC3); in Figure 21, the second node activates CC1 / CC2 or CC3, that is, the second node configures the first node in a two-carrier continuous aggregation configuration (CC1 / CC2), or the second node configures the first node in a single-carrier (CC1 or CC2 or CC3) manner.

[0393] In some embodiments, if the first node reports that the measured maximum power intensity of the interference signal meets a preset requirement, the second node stores the set of component carriers supported by the maximum frequency span reported by the first node and configures the first node according to this set of component carriers. That is, in Figure 22, the second node configures the first node according to two-carrier discontinuous cross-band aggregation (CC1 / CC2). If the first node reports that the measured maximum power intensity of the interference signal does not meet the preset requirement, the second node activates the component carriers of the set of component carriers supported by the maximum frequency span reported by the first node via RRC signaling. The second node activates CC1 of band nX or CC2 of band nY, meaning the second node configures the first node according to a single-carrier (CC1 or CC2) configuration.

[0394] If the first node reports that the measured maximum power intensity of the interference signal meets the preset requirements, then the second node stores the set of component carriers supported by the maximum frequency domain span reported by the first node, and configures the first node according to this set of component carriers. In Figures 23, 24, 25 and 26, the second node is configured as the first node according to the three-carrier inter-band discontinuous aggregation (CC1 / CC2 / CC3). If the maximum power intensity of the interference signal reported by the first node does not meet the preset requirements, the second node activates the component carriers of the component carrier set supported by the maximum frequency domain span reported by the first node via RRC signaling. Specifically, in Figure 23, the second node activates two downlink component carriers from CC1 and CC2 in band X and CC3 in band nY, i.e., the second node configures the first node as a single carrier (CC1, CC2, or CC3); in Figure 24, the second node activates either CC1 or CC2 in band nX, i.e., the second node configures the first node as a two-carrier discontinuous cross-band aggregation (CC1 / CC3 or CC2 / CC3); in Figure 25, the second node activates either CC1 or CC3, i.e., the second node configures the first node as a two-carrier co-band discontinuous aggregation (CC1 / CC2 or CC2 / CC3); in Figure 26, the second node activates either CC1 / CC2 in band nX or band... CC3 in nY means that the second node is configured with the first node in a two-carrier continuous aggregation configuration (CC1 / CC2), or the second node is configured with the first node in a single-carrier configuration (CC3).

[0395] For example, the information on whether the set of component carriers supported by the maximum frequency domain span received by the second node and the maximum power intensity of the interference signal within the component carrier interval in the set of component carriers meet the preset requirements can also be information from other nodes communicating with the second node besides the first node, as shown in Figure 30.

[0396] In Figure 30, within the communication range of the second node, the third node and the nth node will also report to the second node the third node's frequency band combination capability, shared RF link capability, and the maximum frequency domain span supported under the shared RF link capability, as well as the corresponding component carrier set, and whether the maximum power intensity of the interference signal within the component carrier interval meets the capability information. The processing flow of the second node to the third node and the nth node is basically the same as the processing flow of the second node to the first node, and will not be described again here.

[0397] The second node reports its capabilities to the first node via at least one of the following signaling methods:

[0398] Radio Resource Control (RRC) signaling;

[0399] Media Access Control Element (MAC CE); Downlink Control Information (DCI); or

[0400] Non-Access Stratum (NAS) signaling.
