Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a configuration method and device. Background Art

[0002] For the new radio (NR) frequency range (FR) 1, when the sub-carrier spacing (SCS) is 15 kHz, the maximum bandwidth supported by a terminal on a component carrier (CC) is 50 MHz. When the SCS is 30 MHz or 60 MHz, the maximum bandwidth supported by a terminal on a CC is 100 MHz. However, as wireless communication technologies evolve, more spectrum resources will become available, allowing terminals to support data transmission over larger bandwidths. For example, the maximum bandwidth supported by a terminal on a CC can be greater than or equal to 400 MHz. However, there is currently no method to configure a large-bandwidth CC for a terminal. Summary of the Invention

[0003] The present application provides a configuration method and apparatus that can configure a high-bandwidth CC for a terminal.

[0004] To achieve the above objectives, this application adopts the following technical solutions:

[0005] In a first aspect, a configuration method is provided, which can be executed by a terminal. The terminal here can refer to the terminal itself or a processor, module, logical node, chip, or chip system in the terminal that implements the method.

[0006] The method includes: a terminal sending carrier aggregation capability information of the terminal, receiving carrier aggregation configuration information, and communicating with a radio access network node via a first frequency domain resource configured by the carrier aggregation configuration information. The carrier aggregation capability information is used to indicate that the terminal supports data transmission via N1 first carriers, where the bandwidth of the first carrier is less than or equal to the first bandwidth, and N1 is an integer greater than 1; the carrier aggregation configuration information is determined based on the carrier aggregation capability information, where the carrier aggregation configuration information is used to configure the first frequency domain resource, where the first frequency domain resource includes frequency domain resources occupied by M2 second carriers, where the bandwidth of the second carrier is greater than or equal to the second bandwidth, where the second bandwidth is greater than or equal to the first bandwidth, and where M2 is a positive integer.

[0007] Based on the method provided in the first aspect above, the terminal can send carrier aggregation capability information, so that the device receiving the carrier aggregation capability information, such as a wireless access network node, can determine the carrier aggregation capability of the terminal for the first carrier, determine the carrier aggregation capability of the terminal for the second carrier based on the aggregation capability of the terminal for the first carrier, and then configure the terminal on which second carriers to transmit data based on the carrier aggregation capability of the terminal for the second carrier.

[0008] In one possible implementation, M2 is related to a first value, where the first value is a ratio of a third bandwidth to a fourth bandwidth, where the third bandwidth is determined based on the bandwidth of the second carrier, and the fourth bandwidth is determined based on the bandwidth of the first carrier; or, the first value is configured by a wireless access network node.

[0009] Based on the above possible implementation, M2 can be obtained based on N1 and the first value. The first value is related to the third bandwidth and the fourth bandwidth, so the carrier aggregation capability of the terminal for the first carrier can be converted into the carrier aggregation capability of the terminal for the second carrier, thereby determining which second carriers the terminal transmits data on.

[0010] In one possible implementation, the specific values of the third bandwidth and the fourth bandwidth are related to the subcarrier spacing. That is, for different subcarrier spacings, the third bandwidth and the fourth bandwidth can take different values. For example, for a carrier with a 15kHz subcarrier spacing, the third bandwidth is 50MHz and the fourth bandwidth is 200MHz. In this case, the first value is 4; for a carrier with a 30kHz subcarrier spacing, the third bandwidth is 100MHz and the fourth bandwidth is 400MHz. In this case, the first value is 4. For another example, for a carrier with a 15kHz subcarrier spacing, the third bandwidth is 50MHz and the fourth bandwidth is 400MHz. In this case, the first value is 8; for a carrier with a 30kHz subcarrier spacing, the third bandwidth is 100MHz and the fourth bandwidth is 400MHz. In this case, the first value is 4.

[0011] Based on the above possible implementation manner, the third bandwidth and the fourth bandwidth may be determined based on the subcarrier spacing corresponding to the carrier of the terminal operating frequency band, and then the first value may be determined.

[0012] In one possible implementation, the specific values of the third bandwidth and the fourth bandwidth are related to the operating band parameters of the terminal. That is, for carriers located in different operating frequency bands, the third bandwidth and the fourth bandwidth can take different values. For example, for a carrier located in the FR1 frequency band, the third bandwidth is 50MHz and the fourth bandwidth is 200MHz. In this case, the first value is 4; for a carrier located in the FR2 frequency band, the third bandwidth is 200MHz and the fourth bandwidth is 800MHz. In this case, the first value is 4. For another example, for a carrier located in the FR1 frequency band, the third bandwidth is 50MHz and the fourth bandwidth is 400MHz. In this case, the first value is 8; for a carrier located in the FR2 frequency band, the third bandwidth is 200MHz and the fourth bandwidth is 800MHz. In this case, the first value is 4.

[0013] Based on the foregoing possible implementation manner, the third bandwidth and the fourth bandwidth may be determined based on the terminal operating frequency band parameter, and then the first value may be determined.

[0014] In a possible implementation, M2 is further related to a first scaling factor, where the first scaling factor is greater than 1, or the first scaling factor is greater than 0 and less than 1.

[0015] Based on the above possible implementations, M2 can be obtained based on N1, the first value, and the first scaling factor. The first scaling factor is related to the compatibility of the communication system with large bandwidth transmission, so M2 can match the compatibility of the communication system with large bandwidth transmission.

[0016] In a possible implementation, the first frequency domain resources further include frequency domain resources occupied by N2 first carriers, where N2 is a positive integer.

[0017] Based on the foregoing possible implementation manner, the terminal may transmit data on the frequency domain resources occupied by M2 second carriers and the frequency domain resources occupied by N2 first carriers.

[0018] In one possible implementation, N2 is related to a first value, where the first value is a ratio of a third bandwidth to a fourth bandwidth, where the third bandwidth is determined based on a bandwidth of the second carrier, and the fourth bandwidth is determined based on a bandwidth of the first carrier; or, the first value is configured by a wireless access network node.

[0019] Based on the above possible implementation, N2 can be obtained based on N1 and the first value. The first value is related to the third bandwidth and the fourth bandwidth, so the carrier aggregation capability of the terminal for the first carrier can be converted into the carrier aggregation capability of the terminal for the first carrier and the second carrier, thereby determining which second carriers the terminal transmits data on.

[0020] In a possible implementation, N2 is further related to a first scaling factor, where the first scaling factor is greater than 1, or the first scaling factor is greater than 0 and less than 1.

[0021] Based on the above possible implementations, N2 can be obtained based on N1, the first value, and the first scaling factor. The first scaling factor is related to the compatibility of the communication system with large bandwidth transmission, so that N2 can match the compatibility of the communication system with large bandwidth transmission.

[0022] In a possible implementation, the carrier aggregation capability information is further used to indicate that the terminal supports common data transmission through M1 second carriers; M1 is an integer greater than 1.

[0023] Based on the above possible implementation manner, the terminal may further report the carrier aggregation capability for the second carrier, so that the radio access network node configures a carrier aggregation mode for the terminal based on the capability.

[0024] In a possible implementation, the third bandwidth is the bandwidth of the second carrier with the largest bandwidth among the M1 second carriers; and the fourth bandwidth is the bandwidth of the first carrier with the largest bandwidth among the N1 first carriers.

[0025] Based on the above possible implementation methods, if the third bandwidth is determined according to the maximum value of the second carrier bandwidth, and the first value is determined according to the maximum value of the first carrier bandwidth, it can be ensured that when the network device arbitrarily configures the second carrier bandwidth (less than or equal to the configurable maximum value), the terminal's processing capability can cope with it.

[0026] In a possible implementation manner, the above method further includes: sending first indication information, where the first indication information is used to indicate a first scaling factor.

[0027] Based on the above possible implementation manner, a device that receives the first indication information, such as a radio access network node, may determine a first scaling factor and then configure a carrier aggregation mode for the terminal according to the first scaling factor.

[0028] In a second aspect, a configuration method is provided, which can be performed by a radio access network node. The radio access network node here can refer to the radio access network node itself, or a processor, module, logical node, chip, or chip system in the radio access network node that implements the method.

[0029] The method includes: a wireless access network node receiving carrier aggregation capability information of a terminal, sending carrier aggregation configuration information, and communicating with the terminal through first frequency domain resources configured by the carrier aggregation configuration information. The carrier aggregation capability information is used to indicate that the terminal supports data transmission via N1 first carriers, the bandwidth of the first carrier is less than or equal to the first bandwidth, and N1 is an integer greater than 1; the carrier aggregation configuration information is determined based on the carrier aggregation capability information, the carrier aggregation configuration information is used to configure first frequency domain resources, the first frequency domain resources include frequency domain resources occupied by M2 second carriers, the bandwidth of the second carrier is greater than or equal to the second bandwidth, the second bandwidth is greater than or equal to the first bandwidth, and M2 is a positive integer.

[0030] Based on the method provided in the second aspect above, according to the carrier aggregation capability information, the wireless access network node can determine the carrier aggregation capability of the terminal for the first carrier, determine the carrier aggregation capability of the terminal for the second carrier based on the aggregation capability of the terminal for the first carrier, and then configure the terminal on which second carriers to transmit data based on the carrier aggregation capability of the terminal for the second carrier.

[0032] Based on the above possible implementation, M2 can be obtained based on N1 and the first value. The first value is related to the third bandwidth and the fourth bandwidth, so the carrier aggregation capability of the terminal for the first carrier can be converted into the carrier aggregation capability of the terminal for the second carrier, thereby determining which second carriers the terminal transmits data on.

[0033] In one possible implementation, the specific values of the third bandwidth and the fourth bandwidth are related to the subcarrier spacing corresponding to the carrier. That is, for different corresponding carriers, the third bandwidth and the fourth bandwidth can take different values. For example, for a carrier with a 15kHz subcarrier spacing, the third bandwidth is 50MHz, and the fourth bandwidth is 200MHz. In this case, the first value is 4; for a carrier with a 30kHz subcarrier spacing, the third bandwidth is 100MHz, and the fourth bandwidth is 400MHz. In this case, the first value is 4. For another example, for a carrier with a 15kHz subcarrier spacing, the third bandwidth is 50MHz, and the fourth bandwidth is 400MHz. In this case, the first value is 8; for a carrier with a 30kHz subcarrier spacing, the third bandwidth is 100MHz, and the fourth bandwidth is 400MHz. In this case, the first value is 4.

[0034] Based on the above possible implementation manner, the third bandwidth and the fourth bandwidth may be determined based on the subcarrier spacing corresponding to the carrier of the terminal operating frequency band, and then the first value may be determined.

[0035] In one possible implementation, the specific values of the third bandwidth and the fourth bandwidth are related to the operating band parameters of the carrier. That is, for carriers located in different operating frequency bands, the third bandwidth and the fourth bandwidth can take different values. For example, for a carrier located in the FR1 frequency band, the third bandwidth is 50 MHz and the fourth bandwidth is 200 MHz. In this case, the first value is 4; for a carrier located in the FR2 frequency band, the third bandwidth is 200 MHz and the fourth bandwidth is 800 MHz. In this case, the first value is 4. For another example, for a carrier located in the FR1 frequency band, the third bandwidth is 50 MHz and the fourth bandwidth is 400 MHz. In this case, the first value is 8; for a carrier located in the FR2 frequency band, the third bandwidth is 200 MHz and the fourth bandwidth is 800 MHz. In this case, the first value is 4.

[0036] Based on the foregoing possible implementation manner, the third bandwidth and the fourth bandwidth may be determined based on the terminal operating frequency band parameter, and then the first value may be determined.

[0037] In a possible implementation, M2 is further related to a first scaling factor, where the first scaling factor is greater than 1, or the first scaling factor is greater than 0 and less than 1.

[0038] Based on the above possible implementations, M2 can be obtained based on N1, the first value, and the first scaling factor. The first scaling factor is related to the compatibility of the communication system with large bandwidth transmission, so M2 can match the compatibility of the communication system with large bandwidth transmission.

[0039] In a possible implementation, the first frequency domain resources further include frequency domain resources occupied by N2 first carriers, where N2 is a positive integer.

[0040] Based on the above possible implementation manner, the terminal can transmit data on the frequency domain resources occupied by M2 second carriers and the frequency domain resources occupied by N2 first carriers.

[0042] Based on the above possible implementation, N2 can be obtained based on N1 and the first value. The first value is related to the third bandwidth and the fourth bandwidth, so the carrier aggregation capability of the terminal for the first carrier can be converted into the carrier aggregation capability of the terminal for the first carrier and the second carrier, thereby determining which second carriers the terminal transmits data on.

[0043] In a possible implementation, N2 is further related to a first scaling factor, where the first scaling factor is greater than 1, or the first scaling factor is greater than 0 and less than 1.

[0044] Based on the above possible implementations, N2 can be obtained based on N1, the first value, and the first scaling factor. The first scaling factor is related to the compatibility of the communication system with large bandwidth transmission, so that N2 can match the compatibility of the communication system with large bandwidth transmission.

The aggregation mode indicates the aggregation mode of the first carrier and the second carrier. The bandwidth of the first carrier is less than or equal to the first bandwidth, and the bandwidth of the second carrier is greater than or equal to the second bandwidth. Since the second bandwidth is greater than or equal to the first bandwidth, the second carrier can be regarded as a large-bandwidth CC.

[0092] Before introducing the technical solution of this application, the relevant technical terms involved in this application are explained. It is understood that these explanations are intended to make this application easier to understand and should not be regarded as limiting the scope of protection claimed in this application.

[0093] 1. Carrier aggregation (CA)

[0094] CA refers to aggregating multiple CCs together to transmit data for the terminal. The terminal can increase the transmission bandwidth by transmitting data through CA technology. In specific applications, the radio access network (RAN) node can configure CA-related information so that the terminal can send and / or receive data on multiple CCs at the same time. In long-term evolution (LTE) and previous communication systems, the terminal can transmit data on one CC, but cannot transmit data on multiple CCs. After CA is introduced in the long-term evolution advanced (LTE-A) system, the terminal can transmit data on multiple CCs, so the uplink and downlink throughput of the terminal can be increased exponentially with the increase in the number of CCs.

[0095] In LTE-A systems, the maximum channel bandwidth of a CC is 20 MHz. In new radio (NR) systems, for FR1, the channel bandwidth of a CC can be up to 100 MHz, and for FR2, the channel bandwidth is even higher. Specifically, for FR1, the transmission bandwidth configuration (expressed as the number of resource blocks (NRBs)) corresponding to different SCSs and CC channel bandwidths (in MHz) is shown in Table 1. For FR2, the transmission bandwidth configuration (expressed as the number of resource blocks (NRBs)) corresponding to different SCSs and CC channel bandwidths (in MHz) is shown in Table 2. The transmission bandwidth configuration refers to the number of radio resource blocks corresponding to the channel bandwidth. FR1 can represent the low- to mid-frequency bands of NR, ranging from 410 MHz to 7125 MHz. FR2 can represent the high-frequency bands of NR, such as millimeter wave. FR2 is further divided into FR2-1 and FR2-2. FR2-1 ranges from 24250 MHz to 52600 MHz, and FR2-2 ranges from 52600 MHz to 71000 MHz.

[0096] Table 1

[0097]

[0098] Table 2

[0099]

[0100] In Table 1 or Table 2, N RB Indicates the number of radio resource blocks (RB source blocks) corresponding to the channel bandwidth. N / A (not applicable) indicates not applicable.

[0101] It can be seen from Table 1 or Table 2 that the terminal supports different transmission bandwidths for different SCSs.

[0102] It is understandable that in addition to the fact that different SCSs affect the transmission bandwidth supported by the terminal, due to the limitations of factors such as the terminal's hardware conditions (such as baseband processing capabilities, radio frequency processing capabilities), the channel bandwidth of a CC supported by the terminal will also vary with the frequency band. In other words, for different frequency bands, the channel bandwidth of a CC supported by the terminal may be different. Therefore, after establishing a connection with the radio access network node, the terminal needs to indicate to the radio access network node the specific channel bandwidth capability supported by the terminal for each frequency band, so that the radio access network node can configure an appropriate transmission bandwidth for the terminal based on the terminal's channel bandwidth capability, and avoid the radio access network node configuring a transmission bandwidth that exceeds the terminal's channel bandwidth capability. The maximum channel bandwidth among the channel bandwidth capabilities reported by the terminal for each frequency band is the maximum channel bandwidth of a CC supported on that frequency band.

[0103] For example, as can be seen from Table 1, for any frequency band of FR1, when the SCS is 15KHz and the channel bandwidth of the CC is 20MHz, the transmission bandwidth is configured to 106 RBs, when the SCS is 30KHz and the channel bandwidth of the CC is 40MHz, the transmission bandwidth is configured to 106 RBs, and when the SCS is 60KHz and the channel bandwidth of the CC is 80MHz, the transmission bandwidth is configured to 107 RBs.

[0104] For example, as can be seen from Table 2, for any frequency band of FR2, the maximum channel bandwidth supported by the terminal when the SCS is reported to be 60 KHz is 200 MHz.

[0105] It is understandable that, in addition to indicating to the radio access network node the maximum channel bandwidth supported by the terminal for each SCS and each frequency band, the terminal can also report its own CA capability to the radio access network node. Based on the aggregation method between multiple CCs, the terminal's CA capability can be divided into: intra-band contiguous carrier aggregation capability, intra-band non-contiguous carrier aggregation capability, and inter-band carrier aggregation capability.

[0106] (1) Intra-band continuous carrier aggregation capability

[0107] Intra-band continuous CA capability means that the terminal supports the joint transmission of data on multiple continuous CCs in a frequency band. Specifically, since the CA capability of the terminal is divided into multiple CA bandwidth levels, different frequency bands can correspond to different CA bandwidth levels. Each CA bandwidth level represents the carrier aggregation mode supported by the terminal in a frequency band. The carrier aggregation mode includes the channel bandwidth after carrier aggregation and the number of continuously aggregated CCs. For each frequency band, the terminal will indicate the CA bandwidth level corresponding to the frequency band or frequency band combination to the radio access network node. The CA capability level can be specifically indicated by radio resource control (RRC) signaling, such as the carrier aggregation bandwidth level (CA bandwidth class) in the terminal capability information (user equipment capability information) signaling. The CA bandwidth level corresponding to FR1 can be shown in Table 3. Table 3 is applicable to all frequency bands of NR FR1.

[0108] Table 3

[0109]

[0110] In Table 3, BW Channel,max Refers to the maximum channel bandwidth among the channel bandwidths of all frequency bands supported by the terminal. For FR1, this value can be 100MHz. Channel_CA Refers to the channel bandwidth after multiple CCs are aggregated. BW Channel Indicates the channel bandwidth of a CC transmission. For example, taking CA bandwidth level G as an example, if the terminal indicates to the radio access network node that it supports CA bandwidth level G for band 41, it means that the terminal can support three consecutive CCs in the frequency domain within band 41 to jointly transmit data, and the channel bandwidth after the three CCs are aggregated is in the range of 100 MHz to 150 MHz.

[0111] In Table 3, a fallback combination is a combination of multiple CA bandwidth levels. The terminal should support falling back to a lower-order CA bandwidth level in the same fallback combination. This is to ensure that when the radio access network node cannot configure according to the CA bandwidth level reported by the terminal, it can at least fall back to the lower-level CA aggregation mode in the fallback combination to configure the terminal, thereby maintaining the connection between the terminal and the network.

[0112] The fourth column of Table 3 shows three fallback combinations: Fallback Combination 1, Fallback Combination 2, and Fallback Combination 3. Every fallback combination must support CA bandwidth level A. Fallback Combination 1 includes at least one of CA bandwidth levels C through E and CA bandwidth level A; Fallback Combination 2 includes at least one of CA bandwidth levels G through L, CA bandwidth level A, and CA bandwidth level B; and Fallback Combination 3 includes at least one of CA bandwidth levels C through E, at least one of CA bandwidth levels M through O, CA bandwidth level A, and CA bandwidth level B.

[0113] In Example 1, a terminal that supports CA bandwidth level E should also support CA bandwidth level A, because CA bandwidth levels A and E both belong to fallback combination 1, and the CA capability corresponding to CA bandwidth level A is weaker than that of CA bandwidth level E.

[0114] In Example 2, a terminal that supports CA bandwidth level G should also support CA bandwidth levels A and B, because these three CA bandwidth levels all belong to fallback combination 2, and the CA capabilities corresponding to CA bandwidth level A or B are weaker than those of CA bandwidth level G.

[0115] Further, the configuration of the channel bandwidth and fallback combination is described. For example, if the terminal reports band1 (G) to the wireless access network node, it means that the CA bandwidth level supported by the terminal for band1 is G. It can be seen from Table 3 that the CA bandwidth level is G, which means that the terminal supports transmission of up to 3 consecutive CCs in band1, and the channel bandwidth range after the 3 CC carriers are aggregated is between 100MHz and 150MHz. Combined with the channel bandwidth capability of 1 CC given in Table 1, if the SCS is 15KHz, the channel bandwidth of 1 CC supported by the terminal in band1 does not exceed 50MHz, then the wireless access network node can configure the terminal with a maximum channel bandwidth of 50MHz for each of the above 3 CCs, and the 3 CCs can be continuously aggregated. The channel bandwidth after aggregation does not exceed 150MHz (3*50=150, and also meets 100MHz <BW Channel_CA ≤150MHz limit). It is understandable that the radio access network node can also configure three consecutive CCs with different channel bandwidths for the terminal. For example, the channel bandwidths of two of the three CCs are 50MHz, and the channel bandwidth of the remaining CC is 30MHz. In this case, the channel bandwidth of the three CCs after carrier aggregation is 130MHz. Alternatively, the radio access network node can also be configured according to the fallback CA bandwidth level B. For example, two consecutive CCs of 40MHz are configured for the terminal. In this case, the channel bandwidth after carrier aggregation of the three CCs is 80MHz. Alternatively, the radio access network node can also be configured for the terminal according to the fallback CA bandwidth level A. For example, one CC of 80MHz is configured. In this case, the total carrier aggregation bandwidth is 80MHz.

[0116] (2) Discontinuous carrier aggregation capability within the frequency band

[0117] Intra-band discontinuous Carrying-Action (CA) capability means that a terminal supports data transmission on multiple discontinuous CCs in a frequency band.

[0118] For example, taking the case where the terminal supports two CCs that are discontinuous in the frequency domain to jointly transmit data on band1, the terminal can report the CA bandwidth level A corresponding to the two CCs to the wireless access network node, that is, the terminal reports a CA combination such as band1(A)+band1(A), which means that the terminal can support two discontinuous CCs on band1, where the channel bandwidth of each CC is limited by the maximum channel bandwidth corresponding to the CC. Since band1 belongs to FR1, the maximum channel bandwidth corresponding to a CC can be obtained by querying Table 1. For example, for the case where the SCS is 15kHz, the maximum channel bandwidth is 50MHz, then the channel bandwidth of each CC in the above two discontinuous CCs does not exceed 50MHz.

[0119] For example, consider a terminal supporting three CCs for shared data transmission on band 2. When the terminal reports the CA combination of band 2(A) + band 2(B), Table 3 shows that CA bandwidth level A indicates support for one CC transmission, while CA bandwidth level B indicates support for two contiguous CCs for carrier aggregation. Therefore, band 2(A) + band 2(B) indicates that the terminal can support a CA combination of three CCs on band 2. These three CCs can be represented by CC1 through CC3. CC1 and CC2 / CC3 are discontinuous in the frequency domain, while CC2 and CC3 are contiguous in the frequency domain (corresponding to band 2(B)). The channel bandwidth of CC1 is limited by the maximum channel bandwidth capability of the single CC reported by the terminal on band 2. Since band 2 belongs to FR1, Table 1 shows that if the SCS is 15 kHz, the maximum channel bandwidth capability is 50 MHz. Table 3 shows that the channel bandwidth range of the two contiguous CCs, CC2 and CC3, after aggregation, is the channel bandwidth of the carriers aggregated for CA bandwidth level B, i.e., [20 MHz, 100 MHz].

[0120] (3) Inter-band carrier aggregation capability

[0121] Inter-band CA capability means that the terminal supports data transmission on multiple CCs in different frequency bands, and the relationship between multiple CCs in the frequency domain can be continuous or discontinuous.

[0122] For example, if a terminal supports two non-contiguous CCs for shared data transmission on bands 1 and 2, and the CA combination reported by the terminal is band 1(A) + band 2(A), it indicates that the terminal supports configuring one CC on band 1 and one CC on band 2, respectively. The channel bandwidth of each CC is limited by the channel bandwidth capabilities reported by the terminal on bands 1 and 2, respectively. As shown in Table 1, for a 15 kHz channel, the channel bandwidth of each CC does not exceed 50 kHz.

[0123] For example, taking the case where a terminal supports three CCs for data transmission on band 1 and band 2, when the CA combination reported by the terminal is band 1 (A) + band 2 (B), it indicates that the terminal supports the configuration of a CA combination of one CC (represented by CC1) on band 1 and two CCs (represented by CC2 and CC3) on band 2. CC1 and CC2 / CC3 are discontinuous in the frequency domain, while CC2 and CC3 are continuous in the frequency domain (corresponding to band 2 (B)). The channel bandwidth of CC1 does not exceed 50 MHz, and the channel bandwidth range after aggregation of the two continuous CCs CC2 and CC3 is the channel bandwidth after carrier aggregation corresponding to CA bandwidth level B, that is, [20 MHz, 100 MHz].

[0124] 2. Large bandwidth transmission

[0125] With the upgrading of wireless communication technology, communication systems can expand to wider spectrums, and there will be more available spectrum resources, so terminals can support data transmission on larger channel bandwidths to increase transmission rates. It should be understood that if a terminal uses one CC for transmission, the channel bandwidth of the terminal is limited (for example, for SCS it is 15kHz, and the channel bandwidth does not exceed 50MHz), while it is easier to increase the transmission bandwidth when the terminal uses multiple CCs for transmission (that is, when carrier aggregation is performed). Therefore, carrier aggregation is suitable for large bandwidth transmission. If you want to expand the channel bandwidth of the terminal and transmit larger data blocks, there are two possibilities:

[0126] (1) Increase the number of carrier aggregation CCs of the terminal.

[0127] If the number of carrier aggregation CCs of the terminal is increased, the large data blocks can be divided into several parts, and these data parts can be transmitted using multiple CCs respectively. Currently, NR terminals can support up to 16 downlink carriers, and there may be more in the future.

[0128] It is understandable that if the transmission bandwidth of a single CC is not changed, increasing the number of CCs in carrier aggregation to increase the terminal's transmission channel bandwidth comes at the expense of downlink control signaling overhead. For example, if a control signaling (e.g., downlink control information (DCI)) can schedule or manage a CC, when the channel bandwidth increases exponentially, the control signaling overhead also increases exponentially, and it also brings complexity to the scheduling management of the radio access network node and the reception management of the terminal. Therefore, another approach can be considered, namely, expanding the maximum channel bandwidth of each CC to transmit terminal data.

[0129] (2) Expand the maximum channel bandwidth of each CC.

[0130] As shown in Table 1, for NR FR1, when the SCS is 15 kHz, the maximum channel bandwidth supported by a terminal in a CC is 50 MHz. When the SCS is 30 MHz or 60 MHz, the maximum channel bandwidth supported by a terminal in a CC is 100 MHz. For millimeter wave (mmWave) frequency bands, the maximum channel bandwidth supported by a terminal in a CC can be greater than or equal to 400 MHz, as shown in Table 2. Alternatively, after the spectrum of the LTE system is released, more continuous spectrum is available for transmission, and a larger channel bandwidth can be configured for the terminal. A channel bandwidth greater than 400 MHz is referred to as a large bandwidth, and a channel bandwidth less than 400 MHz is referred to as a small bandwidth.

[0131] The benefit of expanding the maximum bandwidth of each CC is that if one CC corresponds to one control signaling, then one control signaling can schedule a larger bandwidth, thus saving control signaling overhead. However, there is currently no method to configure a high-bandwidth CC for a terminal.

[0132] To solve the above problems, this application provides the following two configuration methods:

[0133] Method 1: The terminal sends the carrier aggregation capability information of the terminal to the wireless access network node, receives the carrier aggregation configuration information, and communicates with the wireless access network node through the first frequency domain resources configured by the carrier aggregation configuration information. The carrier aggregation capability information of the terminal is used to indicate that the terminal supports the joint transmission of data through N1 first carriers. The carrier aggregation configuration information is determined based on the carrier aggregation capability information. The first frequency domain resources include frequency domain resources occupied by M2 second carriers, the bandwidth of the first carrier is less than or equal to the first bandwidth, the bandwidth of the second carrier is greater than or equal to the second bandwidth, and the second bandwidth is greater than or equal to the first bandwidth. According to this method, the terminal can send carrier aggregation capability information so that the wireless access network node can determine the carrier aggregation capability of the terminal for the first carrier, determine the carrier aggregation capability of the terminal for the second carrier based on the aggregation capability of the terminal for the first carrier, and then configure the terminal on which second carriers to transmit data based on the carrier aggregation capability of the terminal for the second carrier. The specific process of method 1 will be described below. Figure 3 The method is described in detail and will not be repeated here.

[0134] Method 2: The terminal sends the terminal's carrier aggregation capability information to the wireless access network node, receives the carrier aggregation configuration information, and communicates with the wireless access network node through the configured first frequency domain resources. The carrier aggregation capability information is used to indicate at least one aggregation mode of the first carrier and the second carrier, the bandwidth of the first carrier is less than or equal to the first bandwidth, the bandwidth of the second carrier is greater than or equal to the second bandwidth, and the second bandwidth is greater than or equal to the first bandwidth; the first frequency domain resources include frequency domain resources occupied by P1 first carriers and frequency domain resources occupied by Q1 second carriers; P1 and Q1 are obtained based on the carrier aggregation capability information, and P1 and Q1 are not 0 at the same time. According to this method, the wireless access network point can obtain at least one aggregation mode of the first carrier and the second carrier through the terminal's carrier aggregation capability information, determine an aggregation mode that meets or is lower than at least one aggregation mode, and configure the first frequency domain resources according to the aggregation mode, so that the terminal can use P1 first carriers and Q1 second carriers to transmit data together. The specific process of Method 2 will be described below. Figure 4 The method is described in detail and will not be repeated here.

[0135] The method provided in this application can be used in various communication systems. For example, the communication system can be an LTE system, a 5G communication system, a WiFi system, a 3GPP-related communication system, a future evolution communication system (such as: a sixth generation (6G) communication system, etc.), or a system integrating multiple systems, etc., without limitation. Among them, 5G can also be called NR. Figure 1 The method provided in this application is described by taking the communication system 10 shown as an example.

Wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. For example, a wearable device is not only a hardware device, but also a device that achieves powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include devices that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as devices that focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0139] In the present application, the terminal may be a terminal in an Internet of Things (IoT) system. IoT is an important component of the future development of information technology.

Base stations can be macro base stations, micro base stations, pico base stations, small cells, relay stations, or balloon base stations. Multiple base stations can support networks of the same technology mentioned above, or they can support networks of different technologies mentioned above. A base station can include one or more co-sited or non-co-sited TRPs. A RAN node can also be a device that acts as a base station in D2D communication, Internet of Vehicles communication, drone communication, and machine communication. A RAN node can also be a wireless controller in a cloud radio access network (CRAN) scenario. A RAN node can also be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), a radio unit (RU), a roadside unit (RSU) with base station function, a wired access gateway, or a core network element. A RAN node can also be a server, a wearable device, a machine communication device, or an on-board device. For example, the RAN node in V2X technology can be an RSU.The following description uses a base station as an example RAN node. Multiple RAN nodes can be base stations of the same type or different types. A base station can communicate with a terminal or communicate with the terminal through a relay station. A terminal can communicate with multiple base stations using different technologies. For example, a terminal can communicate with a base station supporting an LTE network or a base station supporting a 5G network, and can also support dual connectivity with both LTE and 5G base stations.

[0142] In this application, the CU and DU can be set separately, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). It is understandable that the CU can be divided into a RAN node in the access network, or the CU can be divided into a RAN node in the core network, without limitation here.

[0143] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in an open radio access network (ORAN) system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU.

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the present application.

[0164] It can be understood that in the present application, "used to indicate" can include direct indications and indirect indications, and can also include explicit indications and implicit indications. When describing that a certain indication information is used to indicate A, it can include that the indication information directly indicates A or indirectly indicates A, and it does not mean that the indication information must carry A. The information indicated by a certain information (such as the first indication information below) is called information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, where there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved by means of the arrangement order of each information agreed in advance (such as specified in the protocol), thereby reducing the indication overhead to a certain extent.

[0165] It can be understood that in this application, "when...", "in the case of...", "if" and "if" all mean that corresponding processing will be taken under certain objective circumstances, and do not limit the time, nor do they require judgment actions when implementing them, nor do they mean that there are other limitations.

[0166] It is understood that some optional features in this application may, in certain scenarios, be implemented independently of other features, such as the solution on which they are currently based, to solve corresponding technical problems and achieve corresponding effects. They may also be combined with other features in certain scenarios as needed. Accordingly, the devices provided in this application may also implement these features or functions accordingly, which will not be described in detail here.

[0167] It is understandable that the same step or steps or technical features with the same function in different embodiments of the present application can be referenced to each other.

[0168] It is understood that in the present application, the wireless access network node and / or the terminal may perform some or all of the steps in the present application. These steps are merely examples, and the present application may also perform other steps or variations of various steps. In addition, the steps may be performed in a different order than presented in the present application, and it is possible that not all of the steps in the present application need to be performed.

[0169] It is understandable that the method provided below in this application uses a wireless access network node and a terminal as an example of the execution subject of the interaction diagram to illustrate the method, but this application does not limit the execution subject of the interaction diagram. For example, the wireless access network node in the method provided in the following embodiment of this application may also be a chip, chip system, or processor that supports the wireless access network node to implement the method, or may be a logical node, logical module, or software that can implement all or part of the wireless access network node; the terminal in the method provided below in this application may also be a chip, chip system, or processor that supports the terminal to implement the method, or may be a logical node, logical module, or software that can implement all or part of the terminal.

[0170] like Figure 3 As shown, a configuration method provided by this application may include the following steps:

[0171] S301: The terminal sends the carrier aggregation capability information of the terminal to the radio access network node. Correspondingly, the radio access network node receives the carrier aggregation capability information of the terminal from the terminal.

[0172] In this application, the terminal can be Figure 1 The terminal 102 or terminal 103 in the communication system 10 is shown. The wireless access network node may be Figure 1 A radio access network node 101 in the communication system 10 is shown.

[0173] In one possible implementation, the terminal's carrier aggregation capability information is used by the terminal to report the terminal's carrier aggregation capability to a radio access network node. For example, the terminal's carrier aggregation capability information is used to indicate that the terminal supports data transmission via N1 first carriers, where the bandwidth of the first carrier is less than or equal to the first bandwidth, and N1 is an integer greater than 1.

[0174] In the present application, the N1 first carriers may be carriers within the same frequency band. For example, the N1 first carriers are N1 carriers that are continuous in the frequency domain within band1, or N1 carriers that are discontinuous in the frequency domain within band1. "Discontinuous in the frequency domain" here means that at least two of the N1 first carriers are discontinuous in the frequency domain. Alternatively, the N1 first carriers are carriers of different frequency bands. For example, some of the N1 first carriers are located in band1, and the other part are located in band2. It is understandable that when the N1 first carriers are carriers that are continuous in the frequency domain within the same frequency band, the method for the terminal to report the carrier aggregation capability of the terminal to the radio access network node can refer to the method for the terminal to report the continuous carrier aggregation capability within the frequency band described above. When the N1 first carriers are carriers that are discontinuous in the frequency domain within the same frequency band, the method for the terminal to report the carrier aggregation capability of the terminal to the radio access network node can refer to the method for the terminal to report the discontinuous carrier aggregation capability within the frequency band described above. When the N1 first carriers are carriers of different frequency bands, the manner in which the terminal reports the carrier aggregation capability of the terminal to the radio access network node may refer to the manner in which the terminal reports the inter-frequency band carrier aggregation capability described above.

[0175] Optionally, the carrier aggregation capability information of the terminal can be carried in the terminal capability information (UE capability information). It can be understood that since different terminals have different software and hardware configurations, the terminal can send terminal capability information to the wireless access network node after establishing a connection with the wireless access network node, so that the wireless access network node can perform appropriate configuration for the terminal. The terminal capability information may include the carrier aggregation capability information of the terminal. Specifically, the wireless access network node can obtain the carrier aggregation capability information of the terminal according to the field of the signaling: CA-BandwidthClassNR, wherein the value of CA-BandwidthClassNR can be A, B, C, D, E, F, G, H, I, J, K, L, M, N or O, etc., and each letter corresponds to a different CA bandwidth level. For example, the wireless access network node can determine the carrier aggregation capability of the terminal by querying Table 3.

[0176] Optionally, the first bandwidth may be less than or equal to 400 MHz and greater than or equal to 200 MHz, such as 400 MHz or 300 MHz, or the first bandwidth may be other values, without limitation. For example, in this application, the bandwidth of the first carrier is less than the first bandwidth, so the first carrier can be considered a small-bandwidth CC.

[0177] Optionally, the carrier aggregation capability information of the terminal further indicates that the terminal supports data transmission via M1 second carriers. M1 is an integer greater than 1. That is, the terminal can support data transmission via N1 first carriers, or support data transmission via M1 second carriers. The bandwidth of the second carrier is greater than or equal to the second bandwidth, and the second bandwidth is greater than or equal to the first bandwidth. For example, the first bandwidth is 400 MHz and the second bandwidth is 500 MHz, or the first bandwidth is 200 MHz and the second bandwidth is 300 MHz.

[0178] In the present application, the M1 second carriers may be carriers within the same frequency band. Alternatively, the M1 second carriers may be carriers in different frequency bands. For details, reference may be made to the above description of the N1 first carriers. The M1 second carriers and the N1 first carriers may be carriers in the same frequency band or carriers in different frequency bands. The M1 second carriers and the N1 first carriers may be continuous or discontinuous in the frequency domain, without limitation.

[0179] In the present application, the bandwidth of the second carrier is greater than or equal to the second bandwidth, so the second carrier can be regarded as a large-bandwidth CC.

[0180] S302: The radio access network node sends carrier aggregation configuration information to the terminal. Correspondingly, the terminal receives the carrier aggregation configuration information from the radio access network node.

[0181] The carrier aggregation configuration information is used to configure the first frequency domain resources, and the first frequency domain resources include frequency domain resources occupied by M2 second carriers. Optionally, the first frequency domain resources also include frequency domain resources occupied by N2 first carriers, where N2 is a positive integer.

[0182] Optionally, the carrier aggregation configuration information is carried in RRC signaling (such as an RRC reconfiguration message). Exemplarily, the field SCS-SpecificCarrie in the field sCelltoAddModList included in the RRC reconfiguration message is used to configure the first frequency domain resource.

[0183] It is understandable that the carrier aggregation configuration information is determined based on the carrier aggregation capability information of the terminal. The following four scenarios are used as examples for illustration.

[0184] Scenario 1: The carrier aggregation capability information of the terminal indicates that the terminal supports data transmission through N1 first carriers, and the carrier aggregation configuration information configures frequency domain resources occupied by M2 second carriers.

[0185] It can be understood that in scenario 1, the terminal reports that it supports data transmission through N1 first carriers, and the wireless access network node configures the terminal to transmit data through M2 second carriers. The bandwidth of the second carrier is different from the bandwidth of the first carrier, so the wireless access network node can convert the carrier aggregation capability reported by the terminal for the first carrier into the carrier aggregation capability of the terminal for the second carrier, and then configure how many second carriers the terminal uses to transmit data based on the carrier aggregation capability of the terminal for the second carrier.

[0186] In one possible implementation, the radio access network node may convert the carrier aggregation capability reported by the terminal for the first carrier into the carrier aggregation capability of the terminal for the second carrier by looking up a table (for example, according to Table 4, Table 5, or Table 6 below). The above process can be understood as how to determine the value of M2 based on the value of N1. Methods 1, 2, and 3 are described below.

[0187] Method 1: The value of M2 is related to N1

[0188] Table 4 gives a correspondence between N1 and M2, from which M2 can be determined based on N1.

[0189] Table 4

[0190] N1 M2 1～4 1 5～8 2 9～12 3 13～16 4

[0191] According to the second row of Table 4, when N1 is any integer from 1 to 4, M2 can be 1. When N1 is any integer from 5 to 8, M2 can be 2. When N1 is any integer from 9 to 12, M2 can be 3. When N1 is any integer from 13 to 16, M2 can be 4.

[0192] Method 2: The value of M2 is related to N1 and subcarrier spacing

[0193] Table 5 shows the correspondence between N1, M2, and SCS. In Table 5, the values 1 to 16 in the first row correspond to the values of N1, the values 15 kHz to 60 kHz in the first column correspond to the values of the subcarrier spacing, and the rest correspond to the values of M2.

[0194] Table 5

[0195] SCS\N1 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 15kHz 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 30kHz 1 1 1 1 2 2 2 2 3 3 3 3 4 4 4 4 60kHz 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8

[0196] According to Table 5, when SCS = 15 kHz and N1 = 16 (i.e., the intersection of the second row and the last column), M2 can be 2. When SCS = 30 kHz and N1 = 13 (i.e., the intersection of the third row and the column where N1 = 13), M2 can be 4. When SCS = 60 kHz and N1 = 6 (i.e., the intersection of the fourth row and the column where N1 = 6), M2 can be 3.

[0197] In Table 5, when N1 or SCS takes other values, the value of M2 can be obtained by a method similar to the above example, which will not be repeated here.

[0198] Method 3: The value of M2 is related to N1 and the terminal operating frequency band

[0199] Table 6 shows the correspondence between N1, M2, and the terminal operating frequency band. In Table 6, the values 1 to 16 in the first row correspond to the values of N1, the first column indicates whether the terminal operating frequency band is FR1 or FR2, and the rest are the values of M2.

[0200] Table 6

[0201] N1 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 FR1 1 1 1 1 2 2 2 2 3 3 3 3 4 4 4 4 FR2 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2

[0202] According to Table 6, when the terminal operating frequency band is in FR1, N1=6 (i.e., the intersection of the fourth row and the column where N1=6), M2 can be 2. When the terminal operating frequency band is in FR2, N1=1 (i.e., the intersection of the fourth row and the column where N1=1), M2 can be 2.

[0203] It will be appreciated that Methods 1 to 3 above are merely examples for determining M2. In specific applications, M2 may also be determined by other methods. For example, the value of M2 may be related to N1, the operating frequency band, and the subcarrier spacing. Furthermore, Tables 4 to 6 above are also exemplary. In specific applications, Tables 4 to 6 may also be in other forms without limitation.

[0204] In another possible implementation, M2 is related to a first value R. The first value is the ratio of the third bandwidth to the fourth bandwidth; or the first value is configured by the radio access network node. M2 (corresponding to M2 below), N1 (corresponding to N1 below), and R′ can satisfy the following relationship:

[0205] M2·R≤N1 (1)

[0206] In one possible design, the third bandwidth is determined based on the bandwidth of the second carrier. For example, if the second carrier corresponds to one bandwidth, the third bandwidth is greater than or equal to the bandwidth corresponding to the second carrier. If the second carrier corresponds to multiple bandwidths, the third bandwidth is one of the multiple bandwidths, for example, the third bandwidth is the smallest bandwidth among the multiple bandwidths, or the average of the multiple bandwidths, or the maximum of the multiple bandwidths, or the median of the multiple bandwidths. The fourth bandwidth is determined based on the bandwidth of the first carrier. Exemplarily, the fourth bandwidth is determined based on the bandwidths of N1 first carriers, for example, the fourth bandwidth is the largest bandwidth, or the smallest bandwidth, or the average of the bandwidths of N1 first carriers, or the median of the bandwidths of N1 first carriers. Alternatively, the third bandwidth and / or the fourth bandwidth is configured by the radio access network node, or defined in the protocol.

[0207] Optionally, the specific values of the third bandwidth and the fourth bandwidth are related to the subcarrier spacing. That is to say, for different corresponding carriers, the third bandwidth and the fourth bandwidth can take different values. For example, for a carrier with a subcarrier spacing of 15kHz, the third bandwidth is 50MHz, and the fourth bandwidth is 200MHz. At this time, the first value is 4; for a carrier with a subcarrier spacing of 30kHz, the third bandwidth is 100MHz, and the fourth bandwidth is 400MHz. At this time, the first value is 4. For another example, for a carrier with a subcarrier spacing of 15kHz, the third bandwidth is 50MHz, and the fourth bandwidth is 400MHz. At this time, the first value is 8; for a carrier with a subcarrier spacing of 30kHz, the third bandwidth is 100MHz, and the fourth bandwidth is 400MHz. At this time, the first value is 4.

[0208] Optionally, the specific values of the third bandwidth and the fourth bandwidth are related to the operating band parameters of the terminal. That is to say, for carriers located in different operating frequency bands, the third bandwidth and the fourth bandwidth can take different values. For example, for a carrier located in the FR1 frequency band, the third bandwidth is 50MHz and the fourth bandwidth is 200MHz. In this case, the first value is 4; for a carrier located in the FR2 frequency band, the third bandwidth is 200MHz and the fourth bandwidth is 800MHz. In this case, the first value is 4. For another example, for a carrier located in the FR1 frequency band, the third bandwidth is 50MHz and the fourth bandwidth is 400MHz. In this case, the first value is 8; for a carrier located in the FR2 frequency band, the third bandwidth is 200MHz and the fourth bandwidth is 800MHz. In this case, the first value is 4.

[0209] Optionally, M2 is also related to a first scaling factor S, where the first scaling factor is greater than 1, or the first scaling factor is greater than 0 and less than 1. For example, M2, N1, R, and S may satisfy the following relationship:

[0210] M2·R·S≤N1 (2)

[0211] In the present application, the first scaling factor is used to adjust the number of second carriers and the number of first carriers in the carrier aggregation mode of the second carrier and the first carrier based on the communication system's compatibility with wide-bandwidth transmission. For example, if the communication system has high compatibility with wide-bandwidth transmission and the wide-bandwidth system is optimized relative to the narrow-bandwidth system in terms of control signaling, scheduling process, coding scheme, modulation and demodulation, etc., then the first scaling factor is greater than 0 and less than 1, and the number of second carriers is large. If the communication system has low compatibility with wide-bandwidth transmission and the wide-bandwidth system is less optimized relative to the narrow-bandwidth system in terms of control signaling, scheduling process, coding scheme, modulation and demodulation, etc., then the first scaling factor is greater than 1, and the number of second carriers is small. The above-mentioned compatibility of the communication system with wide-bandwidth transmission includes the compatibility of the terminal with wide-bandwidth transmission and / or the compatibility of the radio access network node with wide-bandwidth transmission. The compatibility of the terminal with wide-bandwidth transmission is related to the baseband processing capability and / or the modulation and demodulation capability of the terminal. Similarly, the compatibility of the radio access network node with wide-bandwidth transmission is related to the baseband processing capability and / or the modulation and demodulation capability of the terminal.

[0212] Optionally, the terminal sends first indication information to the radio access network node, where the first indication information is used to indicate the first scaling factor, so that the radio access network node can determine the first scaling factor according to the first indication information.

[0213] Scenario 2: The carrier aggregation capability information of the terminal is used to indicate that the terminal supports data transmission through N1 first carriers, and the carrier aggregation configuration information configures the frequency domain resources occupied by M2 second carriers and the frequency domain resources occupied by N2 first carriers.

[0214] It can be understood that in scenario 2, the terminal reports that it supports data transmission through N1 first carriers, and the wireless access network node configures the terminal to transmit data through M2 second carriers and N2 first carriers. The bandwidth of the second carrier is different from the bandwidth of the first carrier, so the wireless access network node can convert the carrier aggregation capability reported by the terminal for the first carrier into the terminal's carrier aggregation capability for the second carrier and the first carrier, and then configure the terminal to transmit data through how many second carriers and how many first carriers according to the terminal's carrier aggregation capability for the second carrier and the first carrier.

[0215] Optionally, N2 and M2 are related to the first value R. For an introduction to the first value, refer to the corresponding description in Scenario 1. For example, M2 (corresponding to M2 below), N2 (corresponding to N2 below), R, and N1 (corresponding to N1 below) may satisfy the following relationship:

[0216] N2+M2·R≤N1 (3)

[0217] In formula (3), N1 first carriers are used as carriers on band 1 as an example for explanation. N2 is the first carrier aggregation number configured by the wireless access network node for the terminal on band 1, and M2 is the second carrier aggregation number configured by the wireless access network node for the terminal on band 1. If the bandwidth of the first carrier is 100 MHz and the bandwidth of the second carrier is 400 MHz, and N1 is 6, then R = 400 MHz / 100 MHz = 4. Therefore, for band 1, the wireless access network node can configure N2 = 2, M2 = 1, or N2 = M2 = 1.

[0218] Optionally, N2 and M2 are further related to a first scaling factor S, which is greater than 1, or greater than 0 and less than 1. For a detailed description of the first scaling factor, refer to the description in Scenario 1 above. For example, M2 (corresponding to M2 below), N2 (corresponding to N2 below), R, N1 (corresponding to N1 below), and S may satisfy the following relationship:

[0219] N2+M2·R·S≤N1 (4)

[0220] Optionally, the terminal performs carrier aggregation transmission according to the carrier aggregation configuration information. If the number of the first carrier and / or the second carrier configured by the carrier aggregation configuration information does not meet the restrictions of formula (4), that is, if the calculated value of N2+M2·R·S is greater than the value of N1 reported by the terminal, the terminal may consider that the radio access network configuration is incorrect and proceed with further operations. For example, the terminal may release the RRC connection; or, since one CC corresponds to one secondary cell (SCell), the terminal may also perform carrier aggregation configuration in ascending order according to the cell identity corresponding to each first carrier, or the terminal may perform carrier aggregation configuration in ascending order according to the bandwidth of all carriers corresponding to the first carrier and the second carrier, without restriction.

[0221] Optionally, the terminal may send first indication information to the radio access network node to indicate the first scaling factor.

[0222] Scenario 3: The carrier aggregation capability information of the terminal is used to indicate that the terminal supports data transmission through N1 first carriers or supports data transmission through M1 second carriers, and the carrier aggregation configuration information configures the frequency domain resources occupied by M2 second carriers.

[0223] It can be understood that in scenario 3, the terminal reports support for data transmission through N1 first carriers, or supports data transmission through M1 second carriers. The radio access network node configures the terminal to transmit data through M2 second carriers. The bandwidth of the second carrier is different from the bandwidth of the first carrier. Therefore, the radio access network node can configure the terminal to transmit data through M2 second carriers based on the carrier aggregation capability for the first carrier and / or the carrier aggregation capability for the second carrier reported by the terminal. This is explained in detail below.

[0224] In one possible implementation, the radio access network node may convert the carrier aggregation capability for the first carrier reported by the terminal into the carrier aggregation capability of the terminal for the second carrier, and then configure the number of second carriers through which the terminal transmits data based on the carrier aggregation capability of the terminal for the second carrier. For details, please refer to the description corresponding to the above scenario 1. Different from scenario 1, the third bandwidth may also be determined based on the bandwidths of the M1 second carriers. For example, the third bandwidth may be the largest bandwidth among the bandwidths of the M1 second carriers, or the smallest bandwidth among the bandwidths of the M1 second carriers, or the average of the bandwidths of the M1 second carriers, or the median of the bandwidths of the M1 second carriers.

[0225] In another possible implementation, the radio access network node may configure the terminal to transmit data via M2 second carriers based on the carrier aggregation capability of the terminal for the second carrier, where M2 is less than or equal to M1.

[0226] Scenario 4: The terminal's carrier aggregation capability information is used to indicate that the terminal supports data transmission through N1 first carriers, or supports data transmission through M1 second carriers. The carrier aggregation configuration information configures the frequency domain resources occupied by M2 second carriers and the frequency domain resources occupied by N2 first carriers.

[0227] It can be understood that in scenario 4, the terminal reports that it supports data transmission through N1 first carriers or supports data transmission through M1 second carriers. The radio access network node configures the terminal to transmit data through M2 second carriers and N2 first carriers. The bandwidth of the second carrier is different from the bandwidth of the first carrier. Therefore, the radio access network node can configure the terminal to transmit data through M2 second carriers and N2 first carriers based on the carrier aggregation capability reported by the terminal for the first carrier or the carrier aggregation capability reported by the terminal for the second carrier. This is explained in detail below.

[0228] In one possible implementation, the radio access network node converts the carrier aggregation capability for the first carrier reported by the terminal into the carrier aggregation capability of the terminal for the second carrier and the first carrier, and then configures the terminal to transmit data through M2 second carriers and N2 first carriers according to the carrier aggregation capability of the terminal for the second carrier and the first carrier. Specifically, please refer to the description corresponding to the above scenario 2. Different from scenario 2, the third bandwidth can also be determined based on the bandwidth of the M1 second carriers. For example, the third bandwidth is the largest bandwidth among the bandwidths of the M1 second carriers, or the smallest bandwidth, or the average of the bandwidths of the M1 second carriers, or the median of the bandwidths of the M1 second carriers.

[0229] Another possible implementation method is that the wireless access network node converts the carrier aggregation capability for the second carrier reported by the terminal into the carrier aggregation capability of the terminal for the second carrier and the first carrier, and then configures the terminal to transmit data through M2 second carriers and N2 first carriers according to the carrier aggregation capability of the terminal for the second carrier and the first carrier.

[0230] In one possible design, M2 and N2 are related to a second value R'. The second value is the ratio of the fourth bandwidth to the third bandwidth, or the second value is configured by the radio access network node. For example, M2 (corresponding to M2 below), N2 (corresponding to N2 below), and R' may satisfy the following relationship:

[0231] M2+N2·R′≤M1 (5)

[0232] Optionally, M2 and N2 are also related to a second scaling factor S′. For example, M2, N2, N1, R′, and S′ may satisfy the following relationship:

[0233] M2+N2·R′·S′≤M1 (6)

[0234] Optionally, the second scaling factor is greater than 1, or the second scaling factor is greater than 0 and less than 1. The function of the second scaling factor is to adjust the number of second carriers and the number of first carriers in the carrier aggregation mode of the second carrier and the first carrier according to the compatibility of the communication system with large bandwidth transmission. For example, if the communication system has high compatibility with large bandwidth transmission, the second scaling factor is greater than 1, and the number of second carriers is small. If the communication system has low compatibility with large bandwidth transmission, the second scaling factor is greater than 0 and less than 1, and the number of second carriers is large.

[0235] Optionally, the terminal sends second indication information to the radio access network node, where the second indication information is used to indicate the second scaling factor, so that the radio access network node can determine the second scaling factor according to the second indication information.

[0236] In one possible design, the third bandwidth is determined based on the bandwidth of the second carrier. Exemplarily, the third bandwidth is determined based on the bandwidths of M1 second carriers, for example, the third bandwidth is the largest bandwidth among the bandwidths of the M1 second carriers, or the smallest bandwidth, or the average value of the bandwidths of the M1 second carriers, or the median of the bandwidths of the M1 second carriers. The fourth bandwidth is determined based on the bandwidth of the first carrier. Exemplarily, the fourth bandwidth is determined based on the bandwidths of N1 first carriers, for example, the fourth bandwidth is the largest bandwidth among the bandwidths of the N1 first carriers, or the smallest bandwidth, or the average value of the bandwidths of the N1 first carriers, or the median of the bandwidths of the N1 first carriers. Alternatively, the third bandwidth and / or the fourth bandwidth is configured by the radio access network node or defined in the protocol.

[0237] It can be understood that in addition to the above scenarios, the terminal may also report support for jointly transmitting data through N1 first carriers, and the first frequency domain resources configured by the wireless access network node include the frequency domain resources occupied by N3 first carriers, and N3 is less than or equal to N1. Alternatively, the terminal may also report support for jointly transmitting data through M1 second carriers, and the first frequency domain resources configured by the wireless access network node include the frequency domain resources occupied by M3 second carriers, and M3 is less than or equal to M1. Alternatively, the terminal may also report support for jointly transmitting data through M1 second carriers, and the first frequency domain resources configured by the wireless access network node include the frequency domain resources occupied by N4 first carriers, and N4 is related to R'. For example, M1 (corresponding to the following M1), N4 (corresponding to the following N4) and R' may satisfy the following relationship:

[0238] N4·R′≤M1 (7)

[0239] Optionally, M2 is also related to the second scaling factor S′. For example, M1, N4, R′, and the second scaling factor S′ may satisfy the following relationship:

[0240] N4·R′·S′≤M1 (8)

[0241] Optionally, the second scaling factor is greater than 1, or the second scaling factor is greater than 0 and less than 1. The second scaling factor is used to adjust the number of second carriers and the number of first carriers in the carrier aggregation mode of the second carrier and the first carrier according to the compatibility of the communication system with large bandwidth transmission.

[0242] Optionally, the terminal sends second indication information to the radio access network node, where the second indication information is used to indicate the second scaling factor, so that the radio access network node can determine the second scaling factor according to the second indication information.

[0243] S303: The terminal communicates with the radio access network node through the first frequency domain resource configured by the carrier aggregation configuration information.

[0244] In one possible implementation, a terminal uses carrier aggregation technology to send data to a wireless access network node on a first frequency domain resource. Accordingly, the wireless access network node receives data from the terminal on the first frequency domain resource. Alternatively, the wireless access network node uses carrier aggregation technology to send data to a terminal on a first frequency domain resource. Accordingly, the terminal receives data from the wireless access network node on the first frequency domain resource. The following uses an example of a terminal using carrier aggregation technology to send data to a wireless access network node on the first frequency domain resource.

[0245] Exemplarily, for the above scenario 1 or scenario 3, the terminal simultaneously sends data to the wireless access network node through the frequency domain resources occupied by the M2 second carriers. For the above scenario 2 or scenario 4, the terminal simultaneously sends data to the wireless access network node through the frequency domain resources occupied by the M2 second carriers and the frequency domain resources occupied by the N2 first carriers.

[0246] based on Figure 3 In the method shown, a terminal can transmit carrier aggregation capability information, so that a device receiving the carrier aggregation capability information, such as a radio access network node, can determine the terminal's carrier aggregation capability for a first carrier, determine the terminal's carrier aggregation capability for a second carrier based on the terminal's carrier aggregation capability for the first carrier, and then configure which second carriers the terminal uses to transmit data based on the terminal's carrier aggregation capability for the second carrier.

[0247] like Figure 4 As shown, another configuration method provided by this application may include the following steps:

[0248] S401: The terminal sends the carrier aggregation capability information of the terminal to the radio access network node. Correspondingly, the radio access network node receives the carrier aggregation capability information of the terminal from the terminal.

[0249] In this application, the terminal can be Figure 1 The terminal 102 or terminal 103 in the communication system 10 is shown. The wireless access network node may be Figure 1 A radio access network node 101 in the communication system 10 is shown.

[0250] In one possible implementation, the carrier aggregation capability information is used to indicate at least one aggregation mode of the first carrier and the second carrier. The at least one aggregation mode can be determined based on the hardware conditions of the terminal, such as the RF performance or baseband processing capability of the terminal. The bandwidth of the first carrier is less than or equal to the first bandwidth, the bandwidth of the second carrier is greater than or equal to the second bandwidth, and the second bandwidth is greater than or equal to the first bandwidth. For other descriptions of the first bandwidth and the second bandwidth, please refer to the above Figure 3 The method shown will not be repeated here.

[0251] Exemplarily, the carrier aggregation capability information indicates an aggregation mode, such as the first aggregation mode. The first aggregation mode indicates that the terminal supports data transmission through P2 first carriers and Q2 second carriers, where P2 and Q2 are integers; P2 and Q2 are not zero at the same time.

[0252] Exemplarily, the carrier aggregation capability information indicates two aggregation modes, such as the first aggregation mode and the second aggregation mode as an example. The two aggregation modes include the first aggregation mode and the second aggregation mode. The first aggregation mode indicates that the terminal supports the joint transmission of data through P2 first carriers and Q2 second carriers. The second aggregation mode indicates that the terminal supports the joint transmission of data through P3 first carriers and Q3 second carriers. P2, Q2, P3 and Q3 are integers; P2 and Q2 are not zero at the same time, and P3 and Q3 are not zero at the same time.

[0253] S402: The radio access network node sends carrier aggregation configuration information to the terminal. Correspondingly, the terminal receives the carrier aggregation configuration information from the radio access network node.

[0254] In one possible implementation method, the carrier aggregation configuration information is used to configure the first frequency domain resources, and the first frequency domain resources include P1 frequency domain resources occupied by the first carrier and Q1 frequency domain resources occupied by the second carrier; P1 and Q1 are obtained based on the carrier aggregation capability information; P1 and Q1 are not 0 at the same time.

[0255] It is understandable that when the carrier aggregation capability information indicates an aggregation mode, such as the first aggregation mode, the first aggregation mode indicates that the terminal supports data transmission via P2 first carriers and Q2 second carriers, where P2 is an integer greater than or equal to P1, and Q2 is an integer greater than or equal to Q1.

[0256] It can be understood that when the carrier aggregation capability information indicates two aggregation modes, such as the first aggregation mode and the second aggregation mode, the first aggregation mode indicates that the terminal supports data transmission through P2 first carriers and Q2 second carriers, and the second aggregation mode indicates that the terminal supports data transmission through P3 first carriers and Q3 second carriers, where P3 is an integer greater than or equal to P1, and Q3 is an integer greater than or equal to Q1, or P2 is an integer greater than or equal to P1, and Q2 is an integer greater than or equal to Q1.

[0257] For example, taking P2=Q2=3 and P3=Q3=2 as an example, if the terminal reports support for discontinuous carrier aggregation of 2 first carriers and 2 second carriers (corresponding to P3=Q3=2), and the terminal reports support for discontinuous carrier aggregation of 3 first carriers and 3 second carriers (corresponding to P2=Q2=3), in both cases, the radio access network node can configure 1 first carrier and 1 second carrier for the terminal for discontinuous carrier aggregation, or configure 1 first carrier and 2 second carriers for the terminal for discontinuous carrier aggregation, or configure 2 first carriers and 1 second carrier for the terminal for discontinuous carrier aggregation, or configure 2 first carriers and 2 second carriers for the terminal for discontinuous carrier aggregation, or configure 2 first carriers and 3 second carriers for the terminal for discontinuous carrier aggregation. It should be understood that the same applies to the case of continuous carrier aggregation, which will not be described in detail.

[0258] It is understandable that, in addition to the first polymerization mode and the second polymerization mode, the at least one polymerization mode may also include more polymerization modes, which is not limited.

[0259] S403: The terminal communicates with the radio access network node through the first frequency domain resource configured by the carrier aggregation configuration information.

[0260] In one possible implementation, a terminal uses carrier aggregation technology to send data to a wireless access network node on a first frequency domain resource, and accordingly, the wireless access network node receives data from the terminal on the first frequency domain resource. Alternatively, a wireless access network node uses carrier aggregation technology to send data to a terminal on a first frequency domain resource, and accordingly, the terminal receives data from the wireless access network node on the first frequency domain resource. Taking the example of a terminal using carrier aggregation technology to send data to a wireless access network node on a first frequency domain resource, the terminal simultaneously sends data to the wireless access network node using the frequency domain resources occupied by P1 first carriers and the frequency domain resources occupied by Q1 second carriers.

[0261] based on Figure 4 In the method shown, the terminal determines at least one aggregation mode, that is, at least one carrier aggregation combination of the first carrier and the second carrier supported by the terminal, and reports it to the radio access network node through carrier aggregation capability information. In this way, the radio access network node can obtain at least one aggregation mode of the first carrier and the second carrier based on the carrier aggregation capability information of the terminal, and configure the frequency domain resources of carrier aggregation for the terminal based on the at least one aggregation mode. Figure 3 Compared with the method shown, Figure 4 The method shown does not require conversion of carrier aggregation capabilities and can more intuitively determine appropriate frequency domain resources for the terminal, thereby reducing implementation complexity.
