[0027] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Additionally, the character " / " generally indicates that the preceding and following related objects are in an "or" relationship. Furthermore, "many" in this application means two or more. Moreover, the term "at least one" in this application means any combination of at least two of any one or more of a plurality of objects. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C. Furthermore, the terms "first," "second," and "third" in this application are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0029] As mentioned above, current communication protocol radio frequency indicators are defined based on one radio frequency link for one component carrier. To facilitate understanding of this application, this application will use a radio frequency receiver (i.e., the receiving radio frequency link) as an example to describe the embodiments of this application.

[0030] Figure 1 shows a schematic diagram of the radio frequency (RF) receiver according to an embodiment of this application. The RF receiver 10 is applicable to FDD (Frequency Division Duplexing) standards and includes a receiving RF link 1 and an antenna 1, and a receiving RF link 2 and an antenna 2. The receiving RF link 1 / antenna 1 can receive data from one component carrier (i.e., data transmission of downlink 1) and can receive data from another component carrier (i.e., data transmission of downlink 2). Similarly, the receiving RF link 2 / antenna 2 can also receive data from one component carrier (i.e., data transmission of downlink 1) and can receive data from another component carrier (i.e., data transmission of downlink 2).

[0031] In the 5G NR (New Radio) standard, component carriers are a concept used to support carrier aggregation (CA) or dual connection (DC) technologies. Carrier aggregation or dual connection allows 5G NR 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 multi-carrier operation. Each component carrier can be considered an independent carrier frequency with its own center frequency and bandwidth. That is, in 5G NR, a user equipment (UE) can connect to one or more component carriers simultaneously, and each component carrier can carry its own independent downlink and uplink signals.

[0032] The radio frequency receiver 10 may also include a transmit radio frequency link, a filter, a power amplifier (PA), a transceiver, a mixer (not shown), an analog-to-digital converter (not shown), and other modules. In order to adapt to the TDD (Time Division Duplex) standard, the components may also be different. For example, the filter 1 (i.e., duplexer filter) in the figure may be replaced with a switch. This application does not make any specific limitations.

[0033] It should be noted that the description using the receiving RF link / antenna of an RF receiver as an example is for ease of understanding. In practice, this application is not limited to RF receivers, but can also be an RF transmitter, RF transceiver, etc. That is to say, this application can also be applied to the transmitting RF link / antenna.

[0034] Please refer to Figure 2, which is a flowchart illustrating a communication method according to an embodiment of this application.

[0035] This method can be applied to a first node, which includes at least one radio frequency link / antenna. For example, the first node can be the radio frequency receiver 10 in Figure 1 above, meaning the first node includes at least one receiving radio frequency link / antenna. As shown in Figure 2, the method may include the following steps:

[0036] S21: Send a capability reporting message. The capability reporting message includes the multi-component carrier capability information of the first node's radio frequency link / antenna. The multi-component carrier capability information includes one of the following: the frequency domain span supported by the radio frequency link / antenna; or at least one component carrier combination supported by the radio frequency link / antenna.

[0037] The first node sends a capability reporting message to the second node. The first node and the second node include, but are not limited to, the following nodes: user equipment (UE) in cellular networks, ad hoc networks, point-to-point networks, and satellite communication networks; relay nodes that perform relay functions; base stations (BS); network management; centralized units (CU); core networks; and nodes involved in device-to-device (D2D) communication.

[0038] In at least one component carrier combination, each component carrier combination indicates which component carriers can be combined together to be supported by the RF link / antenna for data transmission. That is, each component carrier combination indicates that two or more component carriers can be combined together to be supported by the RF link / antenna for data transmission.

[0039] The frequency domain span supported by the RF link / antenna represents the frequency domain span supported by the RF link / antenna and the number of component carriers supported within the frequency domain span.

[0040] In this embodiment, the first node sends a capability reporting message to the second node. The capability reporting message includes the multi-component carrier capability information of the first node's radio frequency link / antenna. The multi-component carrier capability information includes the frequency domain span supported by the radio frequency link / antenna, or at least one component carrier combination supported by the radio frequency link / antenna, so that a single radio frequency link / antenna can support the data transmission of two or more component carriers. Under the condition of limited link resources, it can support more component carrier transmissions to a greater extent, thereby improving the data transmission rate.

[0041] The following explanation uses the receiving radio frequency link in Figure 1 as an example of the first node's radio frequency link. The first node sends a capability reporting message to the second node. The capability reporting message includes multi-component carrier capability information of the first node's receiving radio frequency link 1 and / or receiving radio frequency link 2. The multi-component carrier capability information includes at least one component carrier combination supported by receiving radio frequency link 1 and / or receiving radio frequency link 2. Specifically, the component carrier combination supported by receiving radio frequency link 1 indicates that two or more component carriers can be combined together and supported by receiving radio frequency link 1 to receive data from two or more component carriers. Similarly, the component carrier combination supported by receiving radio frequency link 2 indicates that two or more component carriers can be combined together and supported by receiving radio frequency link 2 to receive data from two or more component carriers.

[0042] For example, as shown in Figure 3, which is a schematic diagram of component carrier combination according to an embodiment of this application, a receiving radio frequency link (receiving radio frequency link 1 or receiving radio frequency link 2) of the first node supports receiving data from two component carriers simultaneously.

[0043] Receiver RF link 1 or Receiver RF link 2 can support simultaneous reception of two component carriers, CC1 and CC2. Alternatively, Receiver RF link 1 or Receiver RF link 2 can support simultaneous reception of two component carriers, CC2 and CC3. Alternatively, Receiver RF link 1 or Receiver RF link 2 can support simultaneous reception of two component carriers, CC3 and CC4. In this case, the first node sends a capability reporting message to the second node. The capability reporting message includes multi-component carrier capability information of Receiver RF link 1 or Receiver RF link 2. The multi-component carrier capability information includes at least one component carrier combination supported by Receiver RF link 1 or Receiver RF link 2, namely at least one component carrier combination in {(CC1,CC2),(CC2,CC3),(CC3,CC4)}. For example, it can be {(CC1,CC2),(CC2,CC3),(CC3,CC4)}, or {(CC1,CC2),(CC2,CC3)}, or {(CC1,CC2)}, etc.

[0044] It can be seen that the multi-component carrier capability information of the first node's receiving radio link 1 or receiving radio link 2 includes 3 component carrier combinations, and each component carrier combination includes 2 component carriers. That is to say, after the first node sends a capability reporting message including multi-component carrier capability information, the two component carriers can be combined together and supported by receiving radio link 1 or receiving radio link 2 to receive the data of the two component carriers at the same time. This enables a single receiving radio link to support the reception of data of two component carriers. Under the condition of limited receiving link resources, it can support the reception of more component carriers to a greater extent, thereby improving the downlink transmission rate.

[0045] Alternatively, the capability reporting message may include multi-component carrier capability information of the first node's receiving radio link 1 and / or receiving radio link 2. The multi-component carrier capability information includes the frequency domain span supported by receiving radio link 1 and / or receiving radio link 2, wherein the frequency domain span supported by receiving radio link 1 represents the frequency domain span supported by receiving radio link 1 and the number of component carriers supported within the frequency domain span, and the frequency domain span supported by receiving radio link 2 represents the frequency domain span supported by receiving radio link 2 and the number of component carriers supported within the frequency domain span.

[0046] For example, as shown in Figure 4, which is a schematic diagram of the frequency domain span of an embodiment of this application, a receiving radio frequency link (receiving radio frequency link 1 or receiving radio frequency link 2) of the first node supports simultaneous reception of the frequency domain span Y, which is located in Band X. The frequency domain span Y can include data from at least two component carriers. That is, after the first node sends a capability reporting message including multi-component carrier capability information, multiple component carriers within the frequency domain span Y can be combined together and supported by receiving radio frequency link 1 or receiving radio frequency link 2 to simultaneously receive data from multiple component carriers. This enables a single receiving radio frequency link to support the reception of data from multiple component carriers. Under limited receiving link resources, it can support the reception of more component carriers to a greater extent, thereby improving the downlink transmission rate.

[0047] For ease of understanding, the above embodiments use the radio frequency link of the first node as an example. It should be noted that the capability reporting message refers not only to the multi-component carrier capability information of the receiving radio frequency link 1 and / or receiving radio frequency link 2 of the first node, but also to the multi-component carrier capability information of antenna 1 and / or antenna 2 of the first node. The multi-component carrier capability information of antenna 1 and / or antenna 2 may include the frequency domain span supported by antenna 1 and / or antenna 2 or at least one combination of component carriers. For simplicity, this will not be described in detail here. It is understood that even though subsequent embodiments of this application use the radio frequency link of the first node as an example, they are also applicable to the antennas of the first node.

[0048] Furthermore, the above description uses the receiving radio frequency link of Figure 1 as an example. This application is not limited to this and can also be applied to the transmitting radio frequency link of Figure 1, which will not be described in detail here. Similarly, subsequent embodiments of this application will also be described using the receiving radio frequency link of Figure 1 as an example. As those skilled in the art will understand, this application can also be applied to the transmitting radio frequency link of Figure 1.

[0049] In some embodiments, the multi-component carrier capability information further includes at least one of the following: subcarrier spacing supported by the component carriers; sum of bandwidths supported by the component carriers; operating frequency bands supported by the component carriers; component carrier index of the operating frequency bands supported by the component carriers; bandwidth of the component carrier index of the operating frequency bands supported by the component carriers; and carrier aggregation type or dual-link type supported by the component carriers.

[0050] Continuing with the example of the receiving RF link in Figure 1 and the component carrier combination in Figure 3, the multi-component carrier capability information includes at least one component carrier combination supported by the RF link and its related attribute information. For example, a component carrier combination is {CC1, CC2} supported by receiving RF link 1 or receiving RF link 2. Furthermore, the multi-component carrier capability information also includes at least one of the following: frequency domain span, subcarrier spacing, sum of bandwidth, operating frequency band, carrier aggregation type, or dual-link type of the component carrier combination, that is, the frequency domain span of CC1 and CC2 in the component carrier combination {CC1, CC2}, or the frequency domain span of CC1 and CC2 in the component carrier combination {CC1, CC2}. The subcarrier spacing of C1 and CC2, or the sum of the bandwidths of CC1 and CC2 in the component carrier combination {CC1, CC2}, or the operating frequency band of CC1 and CC2 in the component carrier combination {CC1, CC2}, or the corresponding component carrier index of CC1 and CC2 in the component carrier combination {CC1, CC2}, or the bandwidth of the corresponding component carrier index of CC1 and CC2 in the component carrier combination {CC1, CC2}, or CC1 and CC2 in one or more operating frequency bands in the component carrier combination {CC1, CC2}, or the carrier aggregation type or dual connection type of CC1 and CC2 in the component carrier combination {CC1, CC2}.

[0051] Alternatively, taking the receiving radio frequency link in Figure 1 and the frequency domain span in Figure 4 as examples, the multi-component carrier capability information includes the frequency domain span Y supported by receiving radio frequency link 1 or receiving radio frequency link 2. Furthermore, the multi-component carrier capability information also includes the subcarrier spacing of the frequency domain span Y, the sum of the bandwidths of the component carriers within the frequency domain span Y, the operating frequency band of the frequency domain span Y, the component carrier index of the operating frequency band of the frequency domain span Y, the bandwidth of the component carrier index of the operating frequency band of the frequency domain span Y, and at least one of the carrier aggregation type or dual-link type of the frequency domain span Y.

[0052] In some embodiments, where at least one component carrier combination includes a component carrier combination, a component carrier combination is a component carrier combination among a plurality of component carrier combinations supported by the radio frequency link / antenna.

[0053] Continuing with the example of the receiving radio frequency link in Figure 1 and the component carrier combination in Figure 3, the first node sends a capability reporting message to the second node. This message includes multi-component carrier capability information for either receiving radio frequency link 1 or receiving radio frequency link 2. This multi-component carrier capability information includes at least one component carrier combination supported by receiving radio frequency link 1 or receiving radio frequency link 2, namely {(CC1,CC2),(CC2,CC3),(CC3,CC4)}. Where at least one component carrier combination includes one component carrier combination, this component carrier combination is the component carrier combination among the multiple component carrier combinations supported by the radio frequency link that meets a preset condition. In this case, the component carrier combination reported by the first node to the second node is the component carrier combination in {(CC1,CC2),(CC2,CC3),(CC3,CC4)}.

[0054] In some embodiments, the number of component carriers in the multiple component carrier combinations supported by the RF link / antenna is different; and a component carrier combination is the component carrier combination with the largest number of component carriers among the multiple component carrier combinations supported by the RF link / antenna.

[0055] Taking the receiving radio frequency link in Figure 1 above as an example, when the number of component carriers in the multiple component carrier combinations supported by the receiving radio frequency link is different, as shown in Figure 5, Figure 5 is a schematic diagram of the component carrier combination of an embodiment of this application. Receiving radio frequency link 1 or receiving radio frequency link 2 can support the simultaneous reception of three component carriers CC1, CC2, and CC3 of Band X; receiving radio frequency link 1 or receiving radio frequency link 2 can support the simultaneous reception of two component carriers CC3 and CC4 of Band X. The frequency domain span of the component carrier combination {CC1,CC2,CC3} and {CC3,CC4} is the same. For example, the frequency domain span of both {CC1,CC2,CC3} and {CC3,CC4} is 100MHz.

[0056] It should be noted that in Figure 5, the component carrier combinations {CC1,CC2,CC3} and {CC3,CC4} have the same frequency domain span, but this application is not limited to this.

[0057] Furthermore, the first node sends a capability reporting message, which includes the multi-component carrier capability information of the first node's radio frequency link. The multi-component carrier capability information includes at least one component carrier combination supported by the radio frequency link, namely the component carrier combinations {CC1,CC2,CC3} and {CC3,CC4} supported by the first node's receiving radio frequency link. When at least one component carrier combination includes one component carrier combination, the component carrier combination is the component carrier combination with the largest number of component carriers among the multiple component carrier combinations supported by the radio frequency link. In this case, the multi-component carrier capability information reported by the first node can be {(CC1,CC2,CC3),100MHz}.

[0058] In some embodiments, the frequency domain spans of the multiple component carrier combinations supported by the RF link / antenna are different; a component carrier combination is the component carrier combination with the largest frequency domain span among the multiple component carrier combinations supported by the RF link / antenna.

[0059] Taking the receiving radio frequency link in Figure 1 above as an example, when the number of component carriers in the multiple component carrier combinations supported by the radio frequency link is the same, as shown in Figure 6, Figure 6 is a schematic diagram of the component carrier combination of an embodiment of this application. Receiving radio frequency link 1 or receiving radio frequency link 2 can support the simultaneous reception of two component carriers CC1 and CC2 of Band X, with a frequency domain span of 100MHz; receiving radio frequency link 1 or receiving radio frequency link 2 can support the simultaneous reception of two component carriers CC2 and CC3 of Band X, with a frequency domain span of 80MHz; receiving radio frequency link 1 or receiving radio frequency link 2 can support the simultaneous reception of two component carriers CC3 and CC4 of Band X, with a frequency domain span of 80MHz.

[0060] It should be noted that in Figure 6, the component carrier combinations {CC1,CC2}, {CC2,CC3} and {CC3,CC4} have the same number of component carriers, but this application is not limited to this.

[0061] Furthermore, the first node sends a capability reporting message, which includes the multi-component carrier capability information of the first node's radio frequency link. The multi-component carrier capability information includes at least one component carrier combination supported by the radio frequency link, namely the component carrier combinations {CC1,CC2}, {CC2,CC3}, and {CC3,CC4} supported by the first node's radio frequency link. When at least one component carrier combination includes one component carrier combination, the component carrier combination is the component carrier combination with the largest frequency domain span among the multiple component carrier combinations supported by the radio frequency link. In this case, the multi-component carrier capability information reported by the first node can be {(CC1,CC2),100MHz}.

[0062] In some embodiments, the subcarrier spacing of the multiple component carrier combinations supported by the RF link / antenna is different; a component carrier combination is the component carrier combination with the smallest subcarrier spacing among the multiple component carrier combinations supported by the RF link / antenna.

[0063] Taking the receiving radio frequency link in Figure 1 above as an example, when the subcarrier spacing of the multiple component carrier combinations supported by the radio frequency link is different, as shown in Figure 7, Figure 7 is a schematic diagram of the component carrier combination of an embodiment of this application. The number of component carriers and the frequency domain span of the multiple component carrier combinations supported by receiving radio frequency link 1 or receiving radio frequency link 2 are the same. Receiving radio frequency link 1 or receiving radio frequency link 2 can support the simultaneous reception of two component carriers CC1 and CC2 of Band X, with a frequency domain span of 80MHz; receiving radio frequency link 1 or receiving radio frequency link 2 can support the simultaneous reception of two component carriers CC2 and CC3 of Band X, with a frequency domain span of 80MHz; receiving radio frequency link 1 or receiving radio frequency link 2 can support the simultaneous reception of two component carriers CC3 and CC4 of Band X, with a frequency domain span of 80MHz, wherein the subcarrier spacing (SCS) of CC1 to CC4 are 15kHz, 15kHz, 30kHz, and 30kHz, respectively.

[0064] It should be noted that in Figure 7, the component carrier combinations {CC1,CC2}, {CC2,CC3} and {CC3,CC4} have the same number of component carriers and frequency domain span, but this application is not limited to this.

[0065] Furthermore, the first node sends a capability reporting message, which includes the multi-component carrier capability information of the first node's radio frequency link. The multi-component carrier capability information includes at least one component carrier combination supported by the radio frequency link, namely the component carrier combinations {CC1,CC2}, {CC2,CC3}, and {CC3,CC4} supported by the first node's radio frequency link. When at least one component carrier combination includes one component carrier combination, the component carrier combination is the component carrier combination with the smallest subcarrier spacing among the multiple component carrier combinations supported by the radio frequency link. In this case, the multi-component carrier capability information reported by the first node can be {(CC1,CC2),15kHz}.

[0066] In some embodiments, the sum of the bandwidths of the multiple component carrier combinations supported by the RF link / antenna are different; a component carrier combination is the component carrier combination with the largest sum of bandwidth among the multiple component carrier combinations supported by the RF link / antenna.

[0067] Continuing with the example of the receiving RF link in Figure 1, the first node sends a capability reporting message. This message includes the multi-component carrier capability information of the first node's RF link. The multi-component carrier capability information includes at least one component carrier combination supported by the RF link. For example, the component carriers supported by receiving RF link 1 or receiving RF link 2 include CC1, CC2, CC3, and CC4. If the sum of the bandwidths of the multiple component carrier combinations supported by the RF link is different, for example, 20MHz is supported on CC1, 40MHz on CC2, and 20MHz on CC3, and... When CC4 supports 10MHz, and at least one component carrier combination includes one component carrier combination, a component carrier combination is the component carrier combination with the largest sum of bandwidth among the multiple component carrier combinations supported by the radio frequency link. That is, the reported multi-component carrier capability information can be {(CC_i,CC_j)total_BW_(total bandwidth)i_j}, where CC_i and CC_j are one of CC1 to CC4 in the above example. Correspondingly, the multi-component carrier capability information reported by the first node can be {(CC1,CC2)total_60MHz}.

[0068] It should be noted that the number of component carriers in Band X mentioned above is for reference only. This application does not specifically limit the number of component carriers or the frequency domain span supported by the RF link. For example, the number of component carriers in a frequency band can be 4 or other values. As another example, the frequency domain span supported by an RF link is 100MHz, but in actual device implementation or deployment, it can be less than or greater than 100MHz. Furthermore, the receiving RF link's ability to support component carriers is limited to supporting two or more component carriers within a frequency band. This application does not limit two or more component carriers to one frequency band; that is, a receiving RF link can simultaneously receive data from two or more component carriers, where at least one component carrier is not in the same frequency band as the others.

[0069] As shown in Figure 8, which is a flowchart illustrating a communication method according to an embodiment of this application, this method can be applied to a first node. In some possible implementations, this method can be implemented by a processor calling computer-readable instructions stored in memory, and the method includes the following steps:

[0070] S81: Send a capability reporting message. The capability reporting message includes the multi-component carrier capability information of the first node's radio frequency link / antenna. The multi-component carrier capability information includes one of the following: the frequency domain span supported by the radio frequency link / antenna; or at least one component carrier combination supported by the radio frequency link / antenna.

[0071] The first node sends a capability reporting message to the second node. This message includes the first node's multi-component carrier capability information for its receiving RF link / antenna. This information includes the frequency span supported by the RF link / antenna, or at least one combination of component carriers supported by the RF link / antenna. The frequency span represents the range of frequencies supported by the RF link / antenna and the number of component carriers supported within that span. Each component carrier combination indicates which component carriers can be combined together to be supported by the RF link / antenna for data transmission. In other words, each component carrier combination indicates that two or more component carriers can be combined together to be supported by the RF link / antenna for data transmission.

[0072] S82: Receive a multi-component carrier configuration message from the second node, the multi-component carrier configuration message including one or more component carrier combinations supported by the radio frequency link / antenna of the first node.

[0073] After receiving the capability reporting message sent by the first node, the second node configures a multi-component carrier configuration message and sends it to the first node. The multi-component carrier configuration message includes one or more component carrier combinations supported by the first node's radio frequency link / antenna. For example, the capability reporting message sent by the first node to the second node includes the component carrier combination {(CC1,CC2)} that can be received simultaneously by the aforementioned receiving radio frequency link 1 and receiving radio frequency link 2. The second node determines that the first node has two sets of receiving radio frequency links, namely receiving radio frequency link 1 and receiving radio frequency link 2. Furthermore, the second node learns that the first node's receiving radio frequency link 1 can support the simultaneous reception of two component carriers, CC1 and CC2, of Band X. Based on this, the second node configures the two component carriers of Band X for data transmission for the first node and sends the multi-component carrier configuration message to the first node.

[0074] S83: Select an RF link / antenna for data transmission of one or more component carrier combinations.

[0075] The first node receives a multi-component carrier configuration message sent by the second node, and then the first node can select a radio frequency link / antenna from the multi-component carrier configuration message to perform data transmission of one or more component carrier combinations.

[0076] In some embodiments, when at least one component carrier combination includes multiple component carrier combinations, the multi-component carrier capability information includes at least one of the following: each component carrier combination and its frequency domain span; each component carrier combination and its subcarrier spacing; each component carrier combination and its sum of bandwidths; each component carrier combination and its operating frequency band; each component carrier combination and its number of component carriers; and each component carrier combination and its carrier aggregation or dual connectivity type.

[0077] Taking the receiving radio frequency link in Figure 1 as an example, receiving radio frequency link 1 or receiving radio frequency link 2 can simultaneously receive CC1 and CC2 component carrier data of Band X and CC3 component carrier data of Band Y. The first node sends a capability reporting message to the second node. The capability reporting message includes the multi-component carrier capability information of the first node's radio frequency link. The multi-component carrier capability information includes at least one component carrier combination supported by the radio frequency link, for example, the component carrier combination is the supported {CC1, CC2} and {CC2, CC3}.

[0079] For example, the capability reporting information sent by the first node includes at least one component carrier combination supported by the radio frequency link and its related information. When multiple component carrier combinations have the same frequency domain span, the component carrier capability information includes multiple component carrier combinations and the same frequency domain span. For example, the component carrier combinations supported by a receiving radio frequency link of the first node include {(CC1,CC2,Y),(CC2,CC3,Y),(CC3,CC4,Y)}.

In this case, the multiple component carrier combinations have the same sum of bandwidths BW, and the capability reporting information of the first node can be {(CC1,CC2),(CC2,CC3),(CC3,CC4),total_BW}.

[0082] Alternatively, when multiple component carrier combinations operate in the same frequency band, the component carrier capability information includes multiple component carrier combinations and the same operating frequency band. For example, the component carrier combinations supported by a receiving radio frequency link of the first node include {(CC1,CC2,Band X),(CC2,CC3,Band X),(CC3,CC4,Band X)}. In this case, the operating frequency band of multiple component carrier combinations is the same, which is Band X. The capability reporting information of the first node can be {(CC1,CC2),(CC2,CC3),(CC3,CC4),Band X}.

[0083] Alternatively, when the number of component carriers in multiple component carrier combinations is the same, the component carrier capability information includes multiple component carrier combinations and the same number of component carriers. For example, the component carrier combinations supported by a receiving radio frequency link of the first node include {(CC1,CC2,2),(CC2,CC3,2),(CC3,CC4,2)}.

The capability reporting message includes the multi-component carrier capability information of the first node's radio frequency link. The multi-component carrier capability information includes at least one component carrier combination supported by receiving radio frequency link 1 and / or receiving radio frequency link 2, as well as the adjustment amount of radio frequency indicators. The adjustment amount of radio frequency indicators includes the adjustment amount of reference sensitivity (i.e., ΔREFSENS), the adjustment amount of adjacent channel selectivity (i.e., ΔACS), the adjustment amount of in-band blocking (i.e., ΔIBB), the adjustment amount of narrow band blocking (i.e., ΔNBB), and power imbalance or power spectral density imbalance (PSD).

[0092] In some embodiments, the multi-component carrier capability information further includes at least one of the following: an adjustment amount for the maximum power offset; and an adjustment amount for peak clipping.

[0093] Taking the transmit RF link in Figure 1 above as an example, the first node sends a capability reporting message to the second node. The capability reporting message includes the multi-component carrier capability information of the first node's RF link. The multi-component carrier capability information includes at least one component carrier combination supported by the first node's transmit RF link and transmission adjustment information. The transmission adjustment information includes at least the adjustment amount of the maximum power offset or the adjustment amount of peak clipping. The maximum power offset is the maximum power offset when transmitting a single component carrier. When transmitting multiple component carriers, the transmission power of the multiple component carriers is less than the sum of the terminal's maximum transmit power and the maximum power offset. Peak clipping can be a specific peak clipping ratio or whether peak clipping exists during transmission. For example, it can indicate whether peak clipping is performed during multi-component carrier transmission or specifically indicate the peak clipping ratio of the terminal.

[0094] Alternatively, the first node sends a capability reporting message to the second node. The capability reporting message includes the multi-component carrier capability information of the first node's radio frequency links. The multi-component carrier capability information includes the frequency domain span supported by receiving radio frequency link 1 and / or receiving radio frequency link 2, as well as transmission adjustment information.

The maximum power offset is the maximum power offset for single component carrier transmission. When performing multi-component carrier transmission, the transmission power of its multiple component carriers is less than the sum of the terminal's maximum transmit power and the maximum power offset. Peak clipping can be a specific peak clipping ratio or whether peak clipping exists during transmission. For example, it can indicate whether peak clipping is performed during multi-component carrier transmission, or specifically indicate the peak clipping ratio of the terminal.

[0095] In some embodiments, the method further includes: a first node receiving a multi-component carrier configuration message from a second node, the multi-component carrier configuration message including: one or more component carrier combinations supported by the first node's radio frequency link / antenna; and the first node selecting a radio frequency link / antenna to perform data transmission of one or more component carrier combinations.

[0096] Please refer to Figure 10, which is a flowchart illustrating a communication method according to another embodiment of this application. This method can be applied to a second node. In some possible implementations, the method can be implemented by a processor calling computer-readable instructions stored in memory. As shown in Figure 10, the method may include the following steps:

[0097] S101: Receive capability reporting message. The capability reporting message includes the multi-component carrier capability information of the first node's radio frequency link / antenna. The multi-component carrier capability information includes one of the following: the frequency domain span supported by the radio frequency link / antenna; or at least one component carrier combination supported by the radio frequency link / antenna.

[0098] The second node receives capability reporting messages sent by the first node. The first and second nodes include, but are not limited to, the following nodes: user equipment (UE) in cellular networks, ad hoc networks, point-to-point networks, and satellite communication networks; relay nodes that perform relay functions; base stations (BS); network management; centralized units (CU); core networks; and nodes involved in device-to-device (D2D) communication.

[0099] In at least one component carrier combination, each component carrier combination indicates which component carriers can be combined together to be supported by the radio frequency link for data transmission. That is, each component carrier combination indicates that two or more component carriers can be combined together to be supported by the radio frequency link for data transmission.

[0100] The frequency domain span supported by the radio frequency link indicates the frequency domain span supported by the radio frequency link and the number of component carriers supported within the frequency domain span.

[0101] Taking the receiving radio frequency link in Figure 1 as an example, the capability reporting message includes multi-component carrier capability information of receiving radio frequency link 1 and / or receiving radio frequency link 2 of the first node. This multi-component carrier capability information includes at least one component carrier combination supported by receiving radio frequency link 1 and / or receiving radio frequency link 2. Specifically, the component carrier combination supported by receiving radio frequency link 1 indicates that two or more component carriers can be combined together and supported by receiving radio frequency link 1 to receive data from two or more component carriers. Similarly, the component carrier combination supported by receiving radio frequency link 2 indicates that two or more component carriers can be combined together and supported by receiving radio frequency link 2 to receive data from two or more component carriers.

[0102] Alternatively, the multi-component carrier capability information includes the frequency domain span supported by receiving radio link 1 and / or receiving radio link 2, wherein the frequency domain span may include data from at least two component carriers. That is, after the first node sends a capability reporting message including multi-component carrier capability information, multiple component carriers within the frequency domain span can be combined together and supported by receiving radio link 1 or receiving radio link 2 to receive data from multiple component carriers simultaneously.

[0103] In this embodiment, the second node receives a capability reporting message sent by the first node to the second node. The capability reporting message includes the multi-component carrier capability information of the first node's radio frequency link. The multi-component carrier capability information includes the frequency domain span supported by the radio frequency link, or at least one component carrier combination supported by the radio frequency link, so that a single radio frequency link can support the data transmission of two or more component carriers. Under the condition of limited link resources, it can support more component carrier transmission to a greater extent and improve the data transmission rate.

[0104] As shown in Figure 11, which is a flowchart illustrating a communication method according to another embodiment of this application, this method can be applied to a second node. In some possible implementations, this method can be implemented by a processor calling computer-readable instructions stored in memory, and the method includes the following steps:

[0105] S111: Receive capability reporting message. The capability reporting message includes the multi-component carrier capability information of the first node's radio frequency link / antenna. The multi-component carrier capability information includes one of the following: the frequency domain span supported by the radio frequency link / antenna; or at least one component carrier combination supported by the radio frequency link / antenna.

[0106] The second node receives a capability reporting message sent by the first node. The capability reporting message includes the multi-component carrier capability information of the first node's radio frequency link / antenna. The multi-component carrier capability information includes at least one component carrier combination supported by the radio frequency link / antenna.

[0107] S112: In response to the capability reporting message, a multi-component carrier configuration message is sent to the first node, the multi-component carrier configuration message including one or more component carrier combinations supported by the first node's radio frequency link / antenna.

[0108] In response to the second node receiving the capability reporting message sent by the first node, the second node configures a multi-component carrier configuration message and sends it to the first node, wherein the multi-component carrier configuration message includes one or more component carrier combinations supported by the first node's radio frequency link / antenna.

[0109] Continuing with the example of the receiving radio frequency link in Figure 1 above, for instance, the first node sends a capability reporting message to the second node including the component carrier combination {(CC1,CC2)} that can be simultaneously received by receiving radio frequency link 1 or receiving radio frequency link 2. The second node determines that the first node has two sets of receiving radio frequency links, namely receiving radio frequency link 1 or receiving radio frequency link 2. Furthermore, the second node learns that the first node's receiving radio frequency link 1 can support the simultaneous reception of two component carriers CC1 and CC2 of Band X. Based on this, the second node configures the two component carriers of Band X for the first node to transmit data and sends a multi-component carrier configuration message to the first node. Then, the first node can select a radio frequency link from the multi-component carrier configuration message to perform data transmission of one or more component carrier combinations.

[0110] Furthermore, in some embodiments, the frequency domain span of one or more component carrier combinations is less than or equal to the frequency domain span of at least one component carrier combination; or the sum of the bandwidths of one or more component carrier combinations is less than or equal to the sum of the bandwidths of at least one component carrier combination; or the number of component carriers in one or more component carrier combinations is less than or equal to the number of component carriers in at least one component carrier combination; or the frequency domain spacing of one or more component carrier combinations is greater than or equal to the frequency domain spacing of at least one component carrier combination.

[0111] For example, the capability reporting information sent by the first node includes at least one component carrier combination supported by the radio frequency link and its frequency domain span, such as {(CC1,CC2,CC3),100MHz} supported by the receiving radio frequency link 1 or receiving radio frequency link 2 of the first node. In response to the capability reporting information, the second node generates a multi-component carrier configuration message, wherein the multi-component carrier configuration message includes one or more component carrier combinations supported by the radio frequency link of the first node, wherein the frequency domain span of one or more component carrier combinations is less than or equal to the frequency domain span of at least one component carrier combination. For example, the multi-component carrier configuration message for the receiving radio frequency link includes {(CC1,CC2,CC3),Y}, where Y≤100MHz.

[0112] Alternatively, the capability reporting information sent by the first node includes at least one component carrier combination supported by the radio frequency link and the sum of its bandwidth, such as {(CC1,CC4)total_60MHz} supported by the receiving radio frequency link 1 or receiving radio frequency link 2 of the first node. In this case, in response to the capability reporting information, the second node generates a multi-component carrier configuration message, wherein the multi-component carrier configuration message includes one or more component carrier combinations supported by the radio frequency link of the first node, wherein the sum of the bandwidths of the one or more component carrier combinations is less than or equal to the sum of the bandwidths of at least one component carrier combination. For example, the multi-component carrier configuration message for the receiving radio frequency link may include {(CC1,CC4),total_BW}, where BW≤60MHz.

[0113] Alternatively, the capability reporting information sent by the first node includes at least one component carrier combination supported by the radio frequency link. For example, the receiving radio frequency link 1 or receiving radio frequency link 2 of the first node supports {(CC1,CC2,CC3)}, that is, the number of component carrier combinations supported by it is 3. In this case, in response to the capability reporting information, the second node generates a multi-component carrier configuration message, wherein the multi-component carrier configuration message includes one or more component carrier combinations supported by the radio frequency link of the first node, wherein the number of component carriers in one or more component carrier combinations is less than or equal to the number of component carriers in at least one component carrier combination. For example, the multi-component carrier configuration message for the receiving radio frequency link may include (CC1,CC2), (CC1,CC3), (CC2,CC3), (CC1,CC2,CC3), etc., wherein the number of component carriers in the multi-component carrier configuration message is always less than or equal to 3.

[0114] Alternatively, the capability reporting information sent by the first node includes at least one component carrier combination and its subcarrier spacing supported by the radio frequency link. For example, the receiving radio frequency link 1 or receiving radio frequency link 2 of the first node supports {(CC1,CC2),15kHz}. In this case, in response to the capability reporting information, the second node generates a multi-component carrier configuration message, wherein the multi-component carrier configuration message includes one or more component carrier combinations supported by the radio frequency link of the first node, wherein the subcarrier spacing of one or more component carrier combinations is greater than or equal to the subcarrier spacing of at least one component carrier combination. For example, the multi-component carrier configuration message for the receiving radio frequency link includes {(CC1,CC2),S}, where S≥15kHz.

[0115] In some embodiments, upon receiving a capability reporting message, the second node transmits data to the first node at a preset number of layers via one or more component carrier combinations, wherein the preset number of layers is less than or equal to the product of the number of component carriers in the one or more component carrier combinations and the number of radio frequency links / antennas of the first node.

[0116] For example, upon receiving a capability reporting message, the second node learns that the first node has two receiving radio frequency links, such as receiving radio frequency link 1 or receiving radio frequency link 2. The second node learns that receiving radio frequency link 1 can receive data from the two component carriers CC1 and CC2 of Band X, and receiving radio frequency link 2 can also receive data from the two component carriers CC1 and CC2 of Band X. That is, the second node can transmit two layers of data to the first node via CC1 of Band X, and the second node can also transmit two layers of data to the first node via CC2 of Band X, or the second node can also transmit two layers of data to the first node via CC1 of Band X and one layer of data via CC2 of Band X.

[0117] In this process, the second node transmits data to the first node at a preset number of layers via one or more component carrier combinations. The preset number of layers is the sum of the number of layers transmitted by the second node to the first node via one or more component carriers, Total_layer. The preset number of layers is less than or equal to the product of the number of component carriers in one or more component carrier combinations and the number of radio frequency links of the first node, N_thhd, i.e., Total_layer≤N_thhd, N_thhd=N_RF*N_CC, where N_RF is the number of radio frequency links of the first node, and N_CC is the number of component carriers in one or more component carrier combinations supported by the corresponding radio frequency link of the first node.

[0118] Alternatively, in some embodiments, if no capability reporting message is received, the second node performs one layer of data transmission to the first node via each component carrier in one of one or more component carrier combinations.

[0119] For example, the first node has two receiving radio frequency links, receiving radio frequency link 1 and receiving radio frequency link 2, and receiving radio frequency link 1 or receiving radio frequency link 2 can simultaneously receive data from two component carriers, CC1 and CC2, in Band X. However, when the second node does not receive the receiving radio frequency link capability information reported by the first node indicating that both receiving radio frequency links of the first node can support it, the second node performs one layer of data transmission to the first node through each component carrier in one of the component carrier combinations. That is, the second node sends one layer of data to the terminal in CC1 of Band X, and the second node sends one layer of data to the terminal in CC2 of Band X.

[0120] Furthermore, after the second node receives a report from the first node that both of the first node's receiving radio links support the data reception capability of component carriers CC1 and CC2 in Band A, the second node can adjust the data transmitted in CC1 and / or CC2 in Band X. For example, the second node may transmit two layers of data to the first node in CC1 of Band X; or the second node may transmit two layers of data to the first node in CC2 of Band X; or the second node may transmit two layers of data to the first node in CC1 of Band X and one layer of data in CC2 of Band X. In this case, the sum of the number of layers transmitted by the second node to the first node via one or more component carriers is less than or equal to the product of the number of component carriers in the combination of one or more component carriers and the number of radio links of the first node.
