[0053] In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the related technologies of the embodiments of the present application are described as follows. The related technologies as optional schemes can be combined with the technical solutions of the embodiments of the present application in any manner, and all belong to the protection scope of the embodiments of the present application.

[0054] The capability IE of the terminal is transmitted in the RRC IE. When the RRC connection is established, the terminal reports a series of capabilities, that is, the capability IE. The network side understands the capabilities reported by the terminal, and schedules the terminal according to different capabilities. Therefore, according to different capabilities of the terminal and different radio frequency basic architectures for realizing the capabilities, the terminal is divided into type 1, 2, 3a / 3b and 4a / 4b, a total of 6 different types of terminals. As shown in Table 1:

[0055] Table 1: Terminal classification

[0056] In the existing stage of NR, LTE and 5G dual-link EN-DC is still the dual-link solution chosen by many operators, and the terminal corresponding to the combination capability of EN-DC will also be reported in the capability IE. Among them, in the Multi-Radio Dual Connectivity Parameters (MRDC-Parameters) IE, the interBandMRDC-WithOverlapDL-Bands-r16 signaling will be reported.

[0057] In some embodiments, the definition of the interBandMRDC-WithOverlapDL-Bands-r16 signaling in TS 38.306 can be: indicating whether the UE supports inter-band (NG) EN-DC / NE-DC operation with maximum transmission timing difference (MTTD) / maximum received timing difference (MRTD) according to clause 7.5.2 / 7.6.2 in TS 38.133 [5] and DC MTTD / MRTD according to clause 7.5.5 / 7.6.5 in TS 38.133 [5] and inter-band radio frequency (RF) requirements. If the capability is not reported, the UE supports FDD-FDD or TDD-TDD inter-band operation with DL bands overlapping or partially overlapping with (NG) EN-DC / NE-DC MTTD / MRTD according to clause 7.5.3 / 7.6.3 in TS 38.133 [5] and in-band RF requirements.

[0058] Here, the interBandMRDC-WithOverlapDL-Bands-r16 signaling can be that the terminal reports the terminal support capability according to each band combination. This terminal capability is to realize whether the terminal supports simultaneous transmission on two bands with different numbers but overlapping frequency ranges in the case of overlapping band 42 and band n77 / n78. For example, the signaling at least includes: interBandMRDC-WithOverlapDL-Bands-r16 ENUMERATED{supported} OPTIONAL, at this time, the terminal supports the capability of simultaneous transmission on two bands with different numbers but overlapping frequency ranges.

[0059] If the terminal supports this capability, the MRTD / MTTD of the terminal should follow the corresponding indicators defined in TS 38.133, and the radio frequency indicators of the terminal should meet the corresponding indicators defined in TS 38.101-3. At the same time, according to the terminal's reporting of this capability, the network side can schedule the terminal to perform EN-DC dual-link transmission on band 42 and band n77 / n78 under non-collocated LTE base stations and NR base stations.

[0060] In some embodiments, for the case of 5G carrier aggregation (New Radio Carrier Aggregation, NR CA), the signaling intraBandNR-CA-non-collocated-r18 is introduced, which is used to indicate the terminal's capability of supporting non-collocated base station simultaneous transmission on the same NR frequency band. If the terminal supports this capability, the MRTD / MTTD of the terminal should follow the corresponding indicators defined in TS 38.133, and the radio frequency indicators of the terminal should meet the corresponding indicators defined in TS 38.101-1. At the same time, according to the terminal's reporting of this capability, the network side can schedule the terminal to perform intra-band NR CA transmission on a specific frequency band under two non-collocated NR base stations, which meets the capability of type 2 terminals in Table 1 from the perspective of terminal radio frequency capability. For example, the signaling intraBandNR-CA-non-collocated-r18 can be intraBandNR-CA-non-collocated-r18 ENUMERATED{supported} OPTIONAL.

[0061] In Rel-18, the concept of intra-band non-collocated EN-DC is proposed, considering that when NR reuses LTE frequency bands, operators want to do LTE and NR dual-link on the same frequency band, and considering the non-collocated situation of LTE and NR base stations due to different construction times of NR base stations and LTE base stations, the terminal can support simultaneous connection and transmission with non-collocated LTE and NR base stations, as shown in FIG. 2, which is a schematic diagram of a terminal connecting with LTE base stations and NR base stations according to an embodiment of the present application. In view of the complexity of terminal implementation, only the capability of two component carriers (CC, Component Carrier) each with a maximum of 2*2 MIMO is supported in Rel-18.

[0062] Considering that NR currently has a single wide band, and one band is often subdivided into multiple small bands, each of which is operated by different operators, there will be a situation where the same band, the same operator, obtains two or more separate small bands. At this time, the terminal needs to be able to support intra-band non-contiguous CA, that is, non-contiguous carrier aggregation on a single band. On this basis, since the time of different small bands obtained by the operator is different, the station address of the base station is also different, so the terminal needs to support intra-band non-collocated CA.

[0063] In some embodiments, the definition of intraBandNR-CA-non-collocated-r18 signaling can be: indicating whether the UE supports TDD-TDD intra-band non-collocated NR-CA operation with MTTD / MRTD requirements according to Table 7.5.44-1 / 7.6.4-2 in TS 38.133 [5] and UE RF requirements for intra-band non-collocated NR-CA including 7.10A in TS 38.101-1 [2]. And TDD-TDD intra-band NR-CA operation with MRTD according to Table 7.6.4-1 in TS 38.133 [5] and UE RF requirements for intra-band NR-CA in TS 38.101-1 [2] except 7.10A. If the capability is not reported, the UE only supports TDD-TDD intra-band NR-CA operation with MRTD according to Table 7.6.4-1 in TS 38.133 [5] and UE RF requirements for intra-band NR-CA in TS 38.101-1 [2] except 7.10A. The UE supporting this feature should also support network control indication of MTTD / MRTD and RF requirements for intra-band non-collocated NR-CA through OnCollocatedTypeNR-CA-R181, as defined in TS 38.331 [9].

[0064] However, the capability signaling mode defined in Rel-18, and its corresponding terminal indicators, only support and specify the behavior of the terminal under 2*2 MIMO. The application of the currently introduced signaling is explicitly described in TS 38.101-1, that is, for the UE indicated [intraBandNR-CA-non-collocated-r18] in Table 7.10A.2-2 for the following CA band combinations, if [nonCollocatedTypeNR-CA-r18] is not provided and the UE is configured with maxMIMOlayers with a value less than or equal to 2, the Rx requirements for two receive (Rx) ports apply to each component carrier.

[0065] In some embodiments, the nonCollocatedTypeNR-CA-r18 is configured by the base station to signal in TS 38.331, and the nonCollocatedTypeNR-CA-r18 includes at least "nonCollocatedTypeNR-CA-r18 ENUMERATED{true} OPTIONAL." Here, if the terminal reports the capability of intraBandNR-CA-non-collocated-r18, while the base station does not configure nonCollocatedTypeNR-CA-r18, and the base station configures the terminal's max MIMO-layer to be 2, the terminal works in the form of type2 in Table 1.

[0066] At Rel-18, considering the complexity of the terminal, only intra-band non-collocated CA with a maximum of 2-layer MIMO is supported. At Rel-19, the terminal supports a maximum of 4-layer MIMO in a single frequency band, and therefore, the terminal needs to further support the capability of intra-band non-collocated EN-DC 4-layer MIMO.

[0067] For the terminal's capability of supporting 4*4 MIMO, the current signaling indication and index are not explicitly specified. FIG. 3 is a schematic diagram of a terminal connected with a non-collocated NR base station according to an embodiment of the present application, and FIG. 4 is a schematic diagram of a terminal connected with a non-collocated NR base station according to an embodiment of the present application. As shown in FIGS. 3 and 4, the terminal has two capabilities of supporting 4*4 MIMO, i.e., the dual-link 2+4 MIMO capability shown in FIG. 3 and the dual-link 4+4 MIMO capability shown in FIG. 4. Therefore, how to distinguish the two different capabilities of the terminal and the switching of the terminal under various capabilities need explicit signaling indication, and a new signaling is introduced or the existing signaling and terminal capability reporting are coordinated to enable the network side to explicitly understand the specific terminal capability, to perform corresponding scheduling control, and to realize the switching of different terminal working modes, which is a problem that has not been solved.

[0068] Therefore, the embodiments of the present application provide a wireless communication method, a first device (i.e., a terminal device) supports different capabilities of non-collocated transmission by adopting different radio frequency structures, introduces a new signaling for terminal capability reporting to ensure that a second device (a network side) can explicitly understand the different capabilities of the first device, introduces a new base station configuration signaling, and configures the working state of the first device according to different terminal capabilities and actual use scenarios.

[0069] To make the technical solutions of the embodiments of the present application more comprehensible, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and all of them belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0070] FIG. 5 is a flowchart of a wireless communication method provided by an embodiment of the present application, and the execution subject is a first device. The method can include the following steps.

[0071] In step 501, first capability information of the first device is reported. The first capability information indicates a first capability of supporting intra-band non-collocated CA. The first capability supports maximum N-layer MIMO. N is a positive integer greater than 2.

[0072] In some embodiments, the first capability information is used to represent the first capability of the first device supporting intra-band non-collocated CA. The first capability is used to represent that the first device can simultaneously use a maximum of N transmit antennas and N receive antennas for data transmission, that is, support maximum N-layer MIMO. N is a positive integer greater than 2, for example, N is 4. At this time, each carrier of the first device can support 2+2 MIMO, 2+4 MIMO or 4+4 MIMO capability.

[0073] Here, 4+4 MIMO means that four independent spatial data streams can be simultaneously established between the first device and the second device (base station), and each data stream can be transmitted on different antennas.

[0074] It should be understood that different types of first devices have different first capabilities. Based on the terminal types in the foregoing Table 1, it can be known that the first capability of each carrier of the first device of type 2 is 2+2 MIMO; the first capability of each carrier of the first device of type 3a is 4+2 MIMO; the first capability of each carrier of the first device of type 3b is 4+4 MIMO; the first capability of each carrier of the first device of type 4a is 4+2 MIMO; and the first capability of each carrier of the first device of type 4b is 4+4 MIMO.

[0075] For the capability of supporting 4+2 MIMO and 4+4 MIMO of the first device, the application can introduce new signaling for capability reporting, for example, for the first device supporting type 4a and type 4b, new signaling is introduced to indicate the capability, which can be named as intraBandNR-CA-non-collocated-type4, 1 bit can be used to represent the signaling. The first device reports the capability in the CA parameter capability report when establishing the RRC connection, if the terminal does not report the capability, the network side considers that the terminal does not support the type 4 capability; if the capability value of intraBandNR-CA-non-collocated-type4 is a, the network side considers that the terminal supports the type 4a capability, and the reported capability value is b, the network side considers that the terminal supports the type 4b capability.

[0076] In the embodiment of the application, the first device supports different capability of in-band non-collocated carrier aggregation, and reports the terminal capability, to ensure that the second device can clearly understand the different capabilities of the first device, and configure the working state of the first device according to different terminal capabilities and actual use scenarios, not only improve the flexibility and adaptability of the first device capability reporting mode, but also improve the accuracy of the second device for capability configuration of the first device, and realize accurate resource scheduling and configuration.

[0077] In some embodiments, the type of the first capability includes one or more of the following: a first type; the first type is a separate radio frequency and baseband capability, and the number of radio frequency links supported by each carrier is a second value; the second value is N; a second type; the second type is a separate radio frequency and baseband capability, and the number of radio frequency links supported by each carrier is the first value or the second value; the first value is less than N; a third type; the third type is a shared radio frequency capability, a separate baseband capability, and the number of radio frequency links supported by each carrier is the second value; a fourth type; the fourth type is a shared radio frequency capability, a separate baseband capability, and the number of radio frequency links supported by each carrier is the first value or the second value; a fifth type; the fifth type is a separate radio frequency and baseband capability, and the number of radio frequency links supported by each carrier is the first value.

[0078] Here, the first value can be 2, and the second value can be 4. The first type can be a type 4b terminal, which has a separate radio frequency and baseband capability based on Table 1 described above, that is, the radio frequency and baseband are integrated on different chips, and the number of radio frequency links supported by each carrier (Component Carrier, CC) of the first device of the first type is the second value, that is, the first device of the first type supports the capability of 4+4 MIMO. The second type can be type 4a, which has a separate radio frequency and baseband capability, and the number of radio frequency links supported by each carrier is 2 or 4; the third type can be type 3b, which has a shared radio frequency capability and a separate baseband capability, and the number of radio frequency links supported by each carrier is 4; the fourth type can be type 3a, which has a shared radio frequency capability and a separate baseband capability, and the number of radio frequency links supported by each carrier is 2 or 4; and the fifth type can be type 2, which has a separate radio frequency and baseband capability, and the number of radio frequency links supported by each carrier is 2.

[0079] In the embodiments of the present application, the first device can have multiple types of capabilities, and the second device receives different capabilities reported by the first device to reasonably schedule and configure resources to meet the needs of different scenarios and ensure that the communication between the first device and the second device is more efficient and accurate.

[0080] In some embodiments, the first capability information includes first sub-capability information representing a first type or second sub-capability information representing a second type; the first sub-capability information or the second sub-capability information is carried in first signaling; and the first capability represents support for the first type or the second type.

[0081] Here, when the first device is of the first type or the second type, it can be reported through first signaling. The first signaling can be intraBandNR-CA-non-collocated-type4, which can use 1 bit to represent the signaling. The first signaling can be "intraBandNR-CA-non-collocated-type4 ENUMERATED{a, b} OPTIONAL." Here, the first signaling refers to selecting one of a and b. The first signaling can be reported in the information element CA-Parameters NR. It can also be reported in other message bodies, and the type of the message body is not limited in the embodiments of the present application.

[0082] Wherein, b can be the first sub-capability information, and a can be the second sub-capability information, respectively used to represent the first device supporting the first type or the second type of capability. The first sub-capability information b indicates that the UE supports 4 MIMO layers in two cells; and the second sub-capability information a indicates that the UE supports 2 MIMO layers in one cell and 4 MIMO layers in another cell.

[0083] The first device, when establishing the RRC connection, in the capability reporting, if the first device does not report the capability, the network side considers that the terminal does not support the type 4 capability. The reported capability value of intraBandNR-CA-non-collocated-type4 is a, and the network side considers that the terminal supports the type 4a capability. The reported capability value is b, and the network side considers that the terminal supports the type 4b capability.

[0084] Here, the first signaling can be a capability reported per band combination (per Band combination), that is, the first device can report different support type 4a / 4b capabilities on different BC frequency bands supported by the first device.

[0085] In the embodiment of the present application, the first type and the second type of capability can be reported through the first signaling, which improves the accuracy of terminal capability reporting, so that the second device can quickly perform resource scheduling and configuration based on the reported capability after receiving the capability reported by the first device, and the speed and accuracy of wireless communication are improved.

[0086] In some embodiments, the first capability information includes third sub-capability information representing a third type or fourth sub-capability information representing a fourth type; the third sub-capability information or the fourth sub-capability information is carried in the second signaling; and the first capability represents support for the third type or the fourth type.

[0087] Here, the first device for the third type or the fourth type can be reported through the second signaling. The second signaling can be an intraBandNR-CA-non-collocated-type3 signaling. The content of the second signaling can be “intraBandNR-CA-non-collocated-type3 ENUMERATED{a, b} OPTIONAL,” and the second signaling can be reported in the information element CA-Parameters NR. It can also be reported in other message bodies. The type of the message body is not limited in the embodiment of the present application.

[0088] Wherein, b can be third sub-capability information, and a can be fourth sub-capability information, respectively used to represent that the first device supports a third type or a fourth type of capability. The third sub-capability information b indicates that the UE supports 4 MIMO layers in two cells; and the fourth sub-capability information a indicates that the UE supports 2 MIMO layers in one cell and 4 MIMO layers in another cell.

[0089] When establishing the RRC connection, the first device reports the capability in the capability report. If the first device does not report the capability, the network side considers that the terminal does not support the type 3 capability. The reported capability value of intraBandNR-CA-non-collocated-type3 is a, and the network side considers that the terminal supports the type 3a capability. The reported capability value is b, and the network side considers that the terminal supports the type 3b capability.

[0090] Here, the second signaling can be a capability reported per Band combination, that is, the first device can report different support type 3a / 3b capabilities on different BC frequency bands supported by the first device.

[0091] In the embodiments of the present application, the third type and the fourth type of capability can be reported through the second signaling, which improves the accuracy of the terminal capability report, so that the second device can quickly perform resource scheduling and configuration based on the reported capability after receiving the capability reported by the first device, and the speed and accuracy of wireless communication are improved.

[0092] In some embodiments, the first capability information further includes fifth sub-capability information representing a fifth type; the fifth sub-capability information is carried in third signaling; and the first capability represents support for the fifth type.

[0093] Here, the first device can report the fifth type through the third signaling. The third signaling can be intraBandNR-CA-non-collocated-r18, the content of the third signaling can be “intraBandNR-CA-non-collocated-r18 ENUMERATED{supported} OPTIONAL,” and the third signaling can be reported in the information element CA-Parameters NR. It can also be reported in other message bodies, and the type of the message body is not limited in the embodiments of the present application.

[0094] Wherein, supported can be fifth sub-capability information, used to represent that the first device supports the fifth type of capability. The fifth sub-capability information indicates that the UE supports a maximum of 2 MIMO layers in two cells.

[0095] It should be understood that if the first device supports the fifth type, the second device can schedule the terminal to perform intra-band NR CA on a specific frequency band under two non-collocated NR base stations according to the terminal reported capability after the first device reports the capability.

[0096] In the embodiments of the present application, the fifth type of capability can be reported through the third signaling, which improves the accuracy of terminal capability reporting, so that the second device can quickly perform resource scheduling and configuration based on the reported capability after receiving the reported capability of the first device, thereby improving the speed and accuracy of wireless communication.

[0097] In some embodiments, the first capability information is carried in the fourth signaling; the first capability information includes one or more of the following: a third value; the third value indicates that the first capability represents support for the fifth type; a fourth value; the fourth value indicates that the first capability represents support for the fourth type; a fifth value; the fifth value indicates that the first capability represents support for the third type; a sixth value; the sixth value indicates that the first capability represents support for the second type; and a seventh value; the seventh value indicates that the first capability represents support for the first type.

[0098] In the above embodiments, new signaling (first signaling, second signaling and third signaling) is introduced for the first device of type 2, 3 and 4, which can effectively distinguish the capabilities of the first device, but the overall signaling overhead is large. Therefore, in the capability reporting signaling of the first device, the present application introduces a new capability signaling non-collocated-type, i.e. the fourth signaling. The value of the fourth signaling can be as shown in Table 2:

[0099] Table 2: Value table of fourth signaling

[0100] As shown in Table 2, the third value can be 0, if the first capability information of the first device reported by the fourth signaling is 0, it represents that the first device supports the fifth type, i.e. Type 2 capability; the fourth value can be 1, if the first capability information of the first device reported by the fourth signaling is 1, it represents that the first device supports the fourth type, i.e. Type 3a capability; the fifth value can be 2, if the first capability information of the first device reported by the fourth signaling is 2, it represents that the first device supports the third type, i.e. Type 3b capability; the sixth value can be 3, if the first capability information of the first device reported by the fourth signaling is 3, it represents that the first device supports the second type, i.e. Type 4a capability; and the seventh value can be 4, if the first capability information of the first device reported by the fourth signaling is 4, it represents that the first device supports the first type, i.e. Type 4b capability.

[0101] At this time, the second device can configure the working state of the first device according to the non-collocated-type uploaded by the first device, for example, the second device can reply to the corresponding configuration information through the eighth signaling, and the configuration information contains any value in 0 to 4, which is used to indicate the working state of the first device.

[0102] If the first device does not report the capability, it is considered that the first device does not support the non-collocated transmission capability, and the default terminal is a type 1 terminal.

[0103] In the embodiment of the application, the fourth signaling can be used to report the entire capability of the first device, which reduces the signaling overhead, shortens the call setup time, and improves the transmission and communication efficiency.

[0104] In some embodiments, when the first device establishes an RRC connection, the first capability information of the first device can also not be reported. At this time, if the terminal does not report the first capability information, the second device considers that the first device does not support the non-collocated transmission capability, and the first device is a type 1 terminal by default, that is, the first device also has a second capability, the second capability represents the capability of supporting type 1, and type 1 has shared radio frequency and baseband capability.

[0105] In the embodiment of the application, when the first device does not perform capability reporting, the first device is considered to not support the non-collocated transmission capability by default, and a default type is set, which reduces the problem of delayed configuration of the second device due to the first device not performing reporting, and improves the communication efficiency.

[0106] In some embodiments, the first device can also receive configuration information; the configuration information is allocated by the second device based on the first capability information; wherein the configuration information is used to indicate the second capability information configured for the first device, and the carrier configuration information; the carrier configuration information is used to indicate the maximum MIMO layer number.

[0107] In some embodiments, after receiving the first capability information reported by the first device, the second device can allocate configuration information for the first device based on the first capability information reported by the first device, and the configuration information is used to configure the working state of the first device.

[0108] The configuration information can include second capability information and carrier configuration information configured for the first device. The second capability information can be the same as the first capability information reported by the first device, for example, the first capability information in the first signaling (intraBandNR-CA-non-collocated-type4) reported by the first device is the first sub-capability information b, and the configuration information fed back by the second device can also be the second capability information b, or the second device can not feed back the configuration information.

[0109] In some embodiments, the carrier configuration information is used to indicate the maximum MIMO layer (max MIMO-layer), i.e., the maximum MIMO layer of each carrier of the first device.

[0110] The configuration information can be configured by introducing the control signaling nonCollocatedTypeNR-CA-type4 of the second device, which can be transmitted in the information element (Cell Group Config) of the second device.

[0111] In the embodiments of the present application, after receiving the capability information reported by the first device, the second device configures the working state of the first device according to different terminal capabilities and actual use scenarios, feeds back the configuration information, reduces the waste or unreasonable phenomenon in network resource allocation, and ensures the efficient use of network resources and communication efficiency.

[0112] In some embodiments, the first capability information is the same as the second capability information; the carrier configuration information includes first carrier configuration information and second carrier configuration information; and the radio frequency indicators and measurement indicators met by the first device include at least one or more of the following: second type of radio frequency indicators and measurement indicators in the case that the first capability information is second sub-capability information, the first carrier configuration information is a first value, and the second carrier configuration information is a second value; fifth type of radio frequency indicators and measurement indicators in the case that the first capability information is second sub-capability information, the first carrier configuration information is a first value, and the second carrier configuration information is a first value; first type of radio frequency indicators and measurement indicators in the case that the first capability information is first sub-capability information, the first carrier configuration information is a second value, and the second carrier configuration information is a second value; second type of radio frequency indicators and measurement indicators in the case that the first capability information is first sub-capability information, the first carrier configuration information is a first value, and the second carrier configuration information is a second value; and fifth type of radio frequency indicators and measurement indicators in the case that the first capability information is first sub-capability information, the first carrier configuration information is a first value, and the second carrier configuration information is a first value.

[0113] It should be noted that the first capability information is the same as the second capability information can mean that, for the first device supporting type 4a and type 4b, the first capability information reported by the first device is the first sub-capability information b, and the second capability information configured by the second device for the first device is also the first sub-capability information b. The first carrier configuration information and the second carrier configuration information respectively correspond to the maximum MIMO layer number of two carriers of the first device.

[0114] Here, the second device can control the intra-band non-collocated CA type4 of the terminal in the information element Cell Group Config. Since the Cell Group Config is configured for one cell group (Cell Group), in the intra-band non-collocated CA, the second device can configure the type 4 capability of the master cell group (MCG) and the secondary cell group (SCG) respectively.

[0115] If the nonCollocatedTypeNR-CA-type4 in the configuration information is configured as a, that is, the second device configures the first device to transmit under the type 4a capability, the max MIMO-layer should satisfy one less than or equal to 2 (which can take the value 1 or 2), and the other less than or equal to 4 (which can take the value 1, 2 or 4) on the MCG and the SCG.

[0116] If the nonCollocatedTypeNR-CA-type4 in the configuration information is configured as b, that is, the second device configures the first device to transmit under the type 4b capability, the max MIMO-layer should satisfy both less than or equal to 4 (which can take the value 1, 2 or 4) on the MCG and the SCG. Here, the maximum value that the second device can configure should satisfy the above conditions, and the actual second device can judge the specific number of layers used by the first device for transmission according to the transmission path of the physical downlink shared channel (PDSCH), and configure the corresponding max MIMO-layer value.

[0117] In some embodiments, after the first device reports the capability based on the first signaling intraBandNR-CA-non-collocated-type4, the second device configures the first device capability and the max MIMO-layer of each carrier based on the control signaling nonCollocatedTypeNR-CA-type4 of the second device, the first device can determine the radio frequency indicators and measurement indicators that the first device meets according to the following Table 3.

[0118] Table 3

[0119] As shown in Table 3, in the case that the first capability information is the second sub-capability information a, the first carrier configuration information is 2, and the second carrier configuration information is 4, the radio frequency indicators and measurement indicators that the first device meets are the radio frequency indicators and measurement indicators of the second type (Type 4a); in the case that the first capability information is the second sub-capability information a, the first carrier configuration information is the first value 2, and the second carrier configuration information is the first value 2, the radio frequency indicators and measurement indicators that the first device meets are the radio frequency indicators and measurement indicators of the fifth type (Type 2); in the case that the first capability information is the first sub-capability information b, the first carrier configuration information is the second value 4, and the second carrier configuration information is the second value 4, the radio frequency indicators and measurement indicators that the first device meets are the radio frequency indicators and measurement indicators of the first type (Type 4b); in the case that the first capability information is the first sub-capability information b, the first carrier configuration information is the first value 2, and the second carrier configuration information is the second value 4, the radio frequency indicators and measurement indicators that the first device meets are the radio frequency indicators and measurement indicators of the second type (Type 4a); in the case that the first capability information is the first sub-capability information b, the first carrier configuration information is the first value 2, and the second carrier configuration information is the first value 2, the radio frequency indicators and measurement indicators that the first device meets are the radio frequency indicators and measurement indicators of the fifth type (Type 2).

[0120] In the embodiments of the present application, based on the capability information reported by the first device and the configuration information fed back by the second device, the working state and the communication indicators of the terminal can be quickly determined, and the communication efficiency and accuracy are improved.

[0121] In some embodiments, the first capability information is the same as the second capability information; the carrier configuration information comprises third carrier configuration information and fourth carrier configuration information; and the radio frequency indicators and measurement indicators that the first device satisfies comprise at least one or more of the following: fourth type of radio frequency indicators and measurement indicators in a case where the first capability information is fourth sub-capability information, the third carrier configuration information is a first value, and the fourth carrier configuration information is a second value; fourth type of radio frequency indicators and measurement indicators in a case where the first capability information is fourth sub-capability information, the third carrier configuration information is a first value, and the fourth carrier configuration information is a first value; third type of radio frequency indicators and measurement indicators in a case where the first capability information is third sub-capability information, the third carrier configuration information is a second value, and the fourth carrier configuration information is a second value; third type of radio frequency indicators and measurement indicators in a case where the first capability information is third sub-capability information, the third carrier configuration information is a first value, and the fourth carrier configuration information is a second value; and third type of radio frequency indicators and measurement indicators in a case where the first capability information is third sub-capability information, the third carrier configuration information is a first value, and the fourth carrier configuration information is a first value.

[0122] It should be noted that the first capability information being the same as the second capability information can mean that, for a first device supporting type 3a and type 3b, the first capability information reported by the first device is first sub-capability information b, and the second capability information configured by the second device for the first device is also b. The third carrier configuration information and the third carrier configuration information respectively correspond to the maximum MIMO layer number of the two carriers of the first device.

[0123] Here, for a first device supporting type 3a and type 3b, the capability can be indicated by the second signaling intraBandNR-CA-non-collocated-type3. When establishing an RRC connection, the first device reports the capability in the capability report of CA-Parameters NR. If the first device does not report the capability, the second device considers that the first device does not support the type 3 capability. If the reported capability value of intraBandNR-CA-non-collocated-type3 is a, the second device considers that the first device supports the type 3a capability, and if the reported capability value is b, the second device considers that the first device supports the type 3b capability.

[0124] The second device can control the intra-band non-collocated CA type 3 of the terminal in the Cell Group Config. Since the Cell Group Config is configured for a cell group (Cell Group), in the intra-band non-collocated CA, the second device can configure the type 3 capability of the master cell group (MCG) and the secondary cell group (SCG) respectively.

[0125] If the nonCollocatedTypeNR-CA-type3 in the configuration information is configured as a, that is, the second device configures the first device to transmit under the type 3a capability, the max MIMO-layer on the MCG and the SCG should meet one less than or equal to 2 (which can be 1 or 2) and the other less than or equal to 4 (which can be 1, 2 or 4).

[0126] If the nonCollocatedTypeNR-CA-type3 in the configuration information is configured as b, that is, the second device configures the first device to transmit under the type 3b capability, the max MIMO-layer on the MCG and the SCG should meet both less than or equal to 4 (which can be 1, 2 or 4). Here, the maximum value that the second device can configure should meet the above conditions, and the second device can actually judge the specific transmission of the first device using several layers according to the transmission path of the physical downlink shared channel (PDSCH), and configure the corresponding max MIMO-layer value.

[0127] In some embodiments, after the first device reports the capability based on the second signaling intraBandNR-CA-non-collocated-type3 and the second device configures the capability of the first device and the max MIMO-layer of each carrier based on the control signaling nonCollocatedTypeNR-CA-type3 of the second device, the first device can determine the radio frequency indicators and measurement indicators that the first device meets according to the following Table 4.

[0128] Table 4

[0129] As shown in Table 4, in the case that the third capability information is the fourth sub-capability information a, the first carrier configuration information is 2, and the second carrier configuration information is 4, the radio frequency indicators and measurement indicators satisfied by the first device are the fourth type (Type 3a) of radio frequency indicators and measurement indicators; in the case that the first capability information is the fourth sub-capability information a, the first carrier configuration information is the first value 2, and the second carrier configuration information is the first value 2, the radio frequency indicators and measurement indicators satisfied by the first device are the fourth type (Type 3a) of radio frequency indicators and measurement indicators; in the case that the first capability information is the third sub-capability information b, the first carrier configuration information is the second value 4, and the second carrier configuration information is the second value 4, the radio frequency indicators and measurement indicators satisfied by the first device are the third type (Type 3b) of radio frequency indicators and measurement indicators; in the case that the first capability information is the third sub-capability information b, the first carrier configuration information is the first value 2, and the second carrier configuration information is the second value 4, the radio frequency indicators and measurement indicators satisfied by the first device are the third type (Type 3b) of radio frequency indicators and measurement indicators; in the case that the first capability information is the third sub-capability information b, the first carrier configuration information is the first value 2, and the second carrier configuration information is the first value 2, the radio frequency indicators and measurement indicators satisfied by the first device are the third type (Type 3b) of radio frequency indicators and measurement indicators.

[0130] In the embodiments of the present application, based on the capability information reported by the first device and the configuration information fed back by the second device, the working state and the communication indicators of the terminal can be quickly determined, and the communication efficiency and accuracy are improved.

[0138] In some embodiments, the first configuration information is carried in the sixth signaling, and the second capability information is third sub-capability information or fourth sub-capability information.

[0139] Here, the sixth signaling can be nonCollocatedTypeNR-CA-type3, and the specific content of the signaling can be "nonCollocatedTypeNR-CA-type3 ENUMERATED{a, b} OPTIONAL," which can be delivered through an information element Cell Group Config or other message bodies.

[0140] If the nonCollocatedTypeNR-CA-type3 is configured as a, that is, the fourth sub-capability information, the second device configures the first device to transmit under the capability of type 3a; if the nonCollocatedTypeNR-CA-type3 is configured as b, that is, the third sub-capability information, the second device configures the first device to transmit under the capability of type 3b.

[0143] Here, the seventh signaling can be nonCollocatedTypeNR-CA-r18, and the signaling content can be "nonCollocatedTypeNR-CA-r18 ENUMERATED{true} OPTIONAL," wherein the second capability information can be true, indicating that the first device reports the capability of intraBandNR-CA-non-collocated-r18, and at the same time, if the second device is configured with nonCollocatedTypeNR-CA-r18, the first device works in the form of type 1; if the second device is not configured with nonCollocatedTypeNR-CA-r18, and the second device configures the terminal max MIMO-layer to be 2, the first device works in the state of type 2.

[0144] In the embodiments of the present application, based on the capability information reported by the first device and the configuration information fed back by the second device, the working state and the communication index of the terminal can be quickly determined, and the communication efficiency and accuracy are improved.

[0145] Here, the present application also provides a switching method of a first device between type 4a / 4b and a terminal type 2 and 1. Wherein, the first device of type 2 can be understood as having 4 radio frequency links, 2 for each carrier, realizing 2*2 MIMO.

[0186] In the embodiments of the present application, the second device introduces new base station configuration signaling after learning the different capabilities of the first device, and determines the configuration information of the first device according to different terminal capabilities and actual use scenarios, configures the working state of the first device, can better cope with diversified business requirements and application scenarios, and improves the flexibility of the present application; at the same time, the second device configures based on the capability reported by the first device, improves the accuracy of capability configuration, and realizes accurate resource scheduling and configuration.

[0187] In some embodiments, the first configuration information is carried in the fifth signaling, and the second capability information is first sub-capability information or second sub-capability information.

[0188] In some embodiments, the fifth signaling can be nonCollocatedTypeNR-CA-type4, and the specific content of the signaling is "nonCollocatedTypeNR-CA-type4 ENUMERATED{a, b} OPTIONAL," wherein if nonCollocatedTypeNR-CA-type4 is configured as a, the first configuration information is the second sub-capability information, that is, the second device configures the first device to transmit under the capability of type 4a; if nonCollocatedTypeNR-CA-type4 is configured as b, the first configuration information is the first sub-capability information, that is, the second device configures the first device to transmit under the capability of type 4b.

[0193] It should be noted that the fifth signaling, the sixth signaling and the seventh signaling can be issued through the information element Cell Group Config, or can be issued through other information bodies.

[0197] In some embodiments, if the first capability information of the first device is not received, it is determined that the second capability information indicates a second capability; the second capability represents support for a sixth type; and the sixth type is a shared radio frequency and baseband capability.

[0198] Here, if the first device does not report the first capability information, it is considered that the first device does not support the non-collocated transmission capability, and the first device is instructed to work in the sixth type, i.e., type 1 type.

[0199] In summary, according to the wireless communication method of the embodiment of the present application, a new base station configuration signaling is introduced, and the configuration information of the first device is determined according to different terminal capabilities and actual use scenarios, so that the working state of the first device is configured, which can better cope with diversified business demands and application scenarios, and improve the flexibility of the present application. At the same time, the second device is configured based on the capability reported by the first device, which improves the accuracy of the capability configuration and realizes accurate resource scheduling and configuration.

[0200] The above introduces the wireless communication method provided by the embodiment of the present application. In order to facilitate understanding of the embodiment of the present application, the possible implementation scheme of the wireless communication method suitable for the embodiment of the present application is introduced based on the interaction process between the terminal (first device) and the network side (second device) as follows.

[0201] Since the terminal can have the capability of realizing in-band non-collocated carrier aggregation through a plurality of different radio frequency structures, and under different terminal capabilities, the network can actually configure different MIMO layers of the terminal, the network side needs to know the specific capability of the terminal in 2layer, 4layer, and radio frequency link. Therefore, the embodiment of the present application introduces a new terminal capability reporting, and cooperates with the existing terminal capability reporting and RRC signaling to explicitly inform the network side of the specific capability, so that the network side can correctly schedule the intra-band non-collocated CA and EN-DC of the terminal.

[0202] The embodiment of the application provides technical solutions for how the network side identifies and judges terminal capability and regulates terminal switching under different capabilities in the case that the terminal supports multiple capabilities simultaneously. The terminal supports different capabilities in type 1, type 2, type 3a / 3b and type 4a / 4b, and the network side needs to be able to configure the terminal with different capabilities according to different terminal capability reports and actual network deployment.

[0203] The embodiment of the application introduces new signaling to indicate the capability of the type 4a and type 4b capability terminal. New base station configuration signaling is introduced for the terminal capability configured by the base station (second device). New signaling is introduced to indicate the capability of the type 3a and type 3b capability terminal. New base station configuration signaling is introduced for the terminal capability configured by the base station. For the switching of the terminal between different types (table 1), the base station is configured according to different terminal capabilities and actual use scenarios, and the terminal should meet the corresponding radio frequency and measurement indicators.

[0204] Embodiment 1

[0205] For the terminal supporting type 4a and type 4b, new signaling can be introduced to indicate the capability. Exemplarily, the signaling is named as intraBandNR-CA-non-collocated-type4, and 1 bit can be used to represent the signaling. When the terminal establishes an RRC connection, if the terminal does not report the capability in the capability report of CA-Parameters NR, the network side considers that the terminal does not support the type 4 capability. If the reported capability value of intraBandNR-CA-non-collocated-type4 is a, the network side considers that the terminal supports the type 4a capability, and if the reported capability value is b, the network side considers that the terminal supports the type 4b capability. Exemplarily, the signaling can be “intraBandNR-CA-non-collocated-type4 ENUMERATED{a, b} OPTIONAL.”

[0206] The signaling is a per Band combination reporting capability, i.e. the terminal can report different support type 4a / 4b capabilities on different BC frequency bands supported. The intraBandNR-CA-non-collocated-type4 is defined as follows: value a means UE support 2 MIMO layers in one cell and 4 MIMO layers in the other cell and value b means UE support 4 MIMO layers in both cells.

[0207] The newly introduced base station control signaling (may be nonCollocatedTypeNR-CA-type4 ENUMERATED {a, b} OPTIONAL) controls the terminal's intra-band non-collocated CA type 4 in the Cell Group Config. Since the Cell Group Config is configured for a Cell Group cell group, in the intra-band non-collocated CA, the base station can configure the type 4 capability of the master cell group (MCG, Master Cell Group) and the secondary cell group (SCG, Secondary Cell Group) respectively.

[0208] If nonCollocatedTypeNR-CA-type4 is configured as a, i.e. the base station configures the terminal to transmit under the type 4a capability, the terminal should meet that one of its max MIMO-layer should be less than or equal to 2 (can take the value of 1 or 2), and the other should be less than or equal to 4 (can take the value of 1, 2 or 4). Here the maximum value that the network can configure should meet the above case, and the actual network can judge the specific transmission of several layers according to the transmission path of PDSCH, and configure the corresponding max MIMO-layer value.

[0209] If nonCollocatedTypeNR-CA-type4 is configured as b, i.e. the base station configures the terminal to transmit under the capability of type 4b, the terminal shall meet that its max MIMO-layer on MCG and SCG shall be less than or equal to 4 (which can take the value of 1, 2 or 4). Here, the maximum value that the network can configure shall meet the above case, and the actual network can determine the specific number of layers for transmission according to the transmission path of PDSCH, and configure the corresponding max MIMO-layer value.

[0210] After the terminal reports the capability, the network configures the terminal capability, and determines the max MIMO-layer of each carrier, the terminal shall meet the radio frequency and measurement indicators according to the following Table 10.

[0211] Table 10 Correspondence between terminal capability and indicators

[0212] Embodiment 2

[0213] For terminals supporting type 3a and type 3b, a new signaling can be introduced to indicate the capability. For example, the signaling is named as intraBandNR-CA-non-collocated-type3, which can use 1 bit to represent the signaling. When establishing the RRC connection, the terminal reports the capability in the CA-Parameters NR, if the terminal does not report the capability, the network side considers that the terminal does not support the type 3 capability. If the reported capability value of intraBandNR-CA-non-collocated-type3 is a, the network side considers that the terminal supports the type 3a capability, and if the reported capability value is b, the network side considers that the terminal supports the type 3b capability. For example, the signaling can be "intraBandNR-CA-non-collocated-type3 ENUMERATED{a, b} OPTIONAL."

[0214] The signaling is a per Band combination reporting capability, i.e. the terminal can report different supported type 3a / 3b capabilities on different BCs supported. The intraBandNR-CA-non-collocated-type3 is defined as follows: value a means UE support 2 MIMO layers in one cell and 4 MIMO layers in the other cell and value b means UE support 4 MIMO layers in both cells.

[0215] The newly introduced base station control signaling (can be nonCollocatedTypeNR-CA-type3 ENUMERATED {a, b} OPTIONAL) controls the terminal's intra-band non-collocated CA type 3 in the Cell Group Config. Since the Cell Group Config is configured for one Cell Group, in intra-band non-collocated CA, the base station can configure the MCG SCG respectively with its type 3 capability.

[0216] If nonCollocatedTypeNR-CA-type3 is configured as a, i.e. the base station configures the terminal to transmit under type 3a capability, the terminal should meet that one of its max MIMO-layer should be less than or equal to 2 (can take the value 1 or 2) and the other should be less than or equal to 4 (can take the value 1, 2 or 4) on MCG and SCG. Here the maximum value that the network can configure should meet the above situation, and the actual network can judge the specific transmission of several layers according to the transmission path of PDSCH and configure the corresponding max MIMO-layer value.

[0217] If nonCollocatedTypeNR-CA-type3 is configured as b, i.e. the base station configures the terminal to transmit under type 3b capability, the terminal should meet that its max MIMO-layer should be less than or equal to 4 (can take the value 1, 2 or 4) on MCG and SCG. Here the maximum value that the network can configure should meet the above situation, and the actual network can judge the specific transmission of several layers according to the transmission path of PDSCH and configure the corresponding max MIMO-layer value.

[0218] After the terminal reports the capability, the network configures the terminal capability, and determines the max MIMO-layer of each carrier, the terminal shall meet the radio frequency and measurement indicators according to the following table 11.

[0219] Table 11: Terminal capability reporting, base station configuration and indicator correspondence

[0220] The above embodiments 1 and 2 respectively design the capability reporting signaling and base station signaling for the terminal supporting type 3 and type 4 capabilities, and limit the base station configuration max MIMO-layer, and under different capability reporting and base station configuration capability and max MIMO-layer configuration, the terminal behavior and the radio frequency and measurement indicators that should be met, the subsequent will regulate how the network side identifies and judges the terminal capability and the terminal switching under different capabilities when the terminal supports multiple capabilities at the same time.

[0221] The terminal supports different capabilities in type 1, type 2, type 3a / 3b and type 4a / 4b, and the network side needs to be able to configure different capabilities for the terminal according to different terminal capability reporting and network actual deployment.

[0222] From the basic radio frequency capability and terminal implementation, including: 1, Type 1 type is a terminal type supported by all terminals. 2, type 2 type terminal and type 4a / 4b type terminal are similar in terminal structure, both are separate terminal radio frequency and baseband capability, the difference is only that the number of radio frequency links supported by each carrier is 2 or 4. Therefore, different combinations of base station signaling can be used to make the terminal work in different states. 3, type 3a / 3b type terminal cannot be switched between type 2 / type 4a / 4b type terminal because it uses a common radio frequency analog front end, as shown in table 1.

[0223] Embodiment 3

[0224] This embodiment is used to illustrate the switching and mutual meeting relationship between the terminal type 4a / 4b and the terminal type 2 and the terminal type 1.

[0225] Based on the foregoing, from the implementation of the radio frequency link architecture, the type 2 type terminal can be understood as having 4 radio frequency links, 2 for each carrier, to implement 2*2 MIMO. Type 4a is considered to have 6 radio frequency links, 2 for carrier 1 and 4 for carrier 2, to implement a maximum of 4*4 MIMO on carrier 2, and only 2*2 MIMO on carrier 1. Type 4b is considered to have 8 radio frequency links, 4 for each carrier to implement 4*4 MIMO.

[0226] Table 12 shows the relationship between different terminal capabilities and the base station configurable terminal working state, as shown in Table 12:

[0227] Table 12

[0228] Embodiment 4

[0229] In view of the current terminal type 2, 3 and 4, new capability signaling is introduced, although the terminal capability can be effectively distinguished, but the overall signaling overhead is large. The main reason for this situation is that different types of terminals are introduced in different releases of 3GPP, therefore, a unified solution is proposed, which can introduce a new non-collocated-type capability signaling in the terminal capability reporting signaling. The value of this signaling can be according to the following table 13:

[0230] Table 13: Non-collocated transmission capability of terminal

[0231] If the terminal does not report this capability, it is considered that the terminal does not support non-collocated transmission capability, and the default terminal is type 1 terminal. If the terminal reports this capability, the network side can configure the terminal according to the non-collocated-type uploaded by the terminal.

[0232] In the embodiment of the application, the terminal adopts different radio frequency structures to support different capabilities of non-collocated transmission, to ensure that the network side can clearly understand the different capabilities of the terminal, and through the combination of special signaling of the network side, the specific working state of the terminal is configured. After receiving the terminal capability, the network side can ensure the cooperation of the spectrum, non-collocated base station and other applications according to the capability supported by the terminal, to ensure the utilization of the spectrum and the throughput of the terminal downlink.
