Description

Technical Field

[0001] The present invention generally relates to the field of mobile communications, and more particularly to device-related reporting aggregated bandwidth capability in mobile communications. Background Art

[0002] Unless otherwise indicated herein, the approaches described in this section are not prior art to the claims listed below and are not admitted to be prior art by inclusion in this section.

[0003] In Long-Term Evolution (LTE) or New Radio (NR) mobile communications, carrier aggregation (CA) technology is introduced. In current CA communications, the 3rd Generation Partnership Project (3GPP) standard defines the specific configuration of CA band combinations related to Frequency Range 1 (FR1) and Frequency Range 2 (FR2). In addition, the 3GPP standard also defines the capability signaling of the user equipment (UE) for the CA band combination. Based on the explicitly defined configuration and the UE capability signaling related to the CA band combination, the UE can report its capabilities to the network node, and the network node can determine how to communicate with the UE based on the UE's capability report.

[0004] Regarding UE capability signaling for CA band combinations, the band combinations and corresponding feature sets constitute the main components of signaling. However, in the current framework, the signaling overhead of UE capability signaling transmitted from the UE to the network node is significantly increased. For example, in an FR1 cross-band CA scenario, when the UE only supports a lower aggregate bandwidth that is not equal to the maximum aggregate bandwidth implicitly specified in the 3GPP standard, the UE must report various potential fallback capabilities, which may cause considerable signaling overhead in the Radio Resource Control (RRC) signaling.

[0005] Therefore, how to reduce the signaling overhead of UE capability reporting for CA communication-related operations has become an important issue in newly developed wireless communication networks. There is an urgent need to provide appropriate solutions to reduce the signaling overhead of UE capability reporting and improve the reporting efficiency of CA communication-related operations.

The method further involves the apparatus determining a channel bandwidth configuration set based on the capability signaling for the multiple aggregate bandwidths and the per-component carrier feature set.

[0023] The embodiments and implementations of the claimed subject matter are described in detail below. However, it should be understood that the disclosed embodiments and implementations are merely illustrations of the claimed subject matter implemented in various forms. The present invention can be implemented in a variety of different forms and should not be construed as being limited to the exemplary embodiments and implementations set forth herein. On the contrary, these exemplary embodiments and implementations are provided so that the description of the present invention is thorough and complete and will fully convey the scope of the present invention to those skilled in the art. In the following description, conventional features and technical details are omitted to avoid unnecessarily obscuring the presented embodiments and implementations.

[0024] Overview

[0025] Embodiments of the present invention relate to various technologies, methods, schemes, and / or solutions related to device-related reporting of aggregate bandwidth capabilities in mobile communications. According to the present invention, the possible solutions may be implemented individually or in combination. That is, while these possible solutions may be described separately below, two or more of them may be implemented in one or more combinations.

[0026] In accordance with the present invention, a UE compatible with CA technology may send capability signaling of multiple aggregated bandwidths at the band combination (BC) level to a network node. Specifically, at the BC level, the capability signaling of each aggregated bandwidth may indicate the maximum aggregated bandwidth across component carriers (CCs). At the feature set per component-carrier (FSPC) level, the UE may send the FSPC to the network node. The FSPC includes at least one set of channel bandwidths supported by the UE for CA.

[0027] Based on the capability signaling of multiple aggregate bandwidths and the maximum aggregate bandwidth indicated by the FSPC, the network node can determine a channel bandwidth configuration set. The channel bandwidth configuration set includes the actual bandwidth used in the channel. The network node can configure the channel bandwidth configuration set of the UE and communicate with the UE based on the channel bandwidth configuration set. More specifically, based on the maximum aggregate bandwidth indicated by the capability signaling of multiple aggregate bandwidths, the network node can determine the appropriate channel bandwidth for communicating with the UE, and the UE does not need to report various potential fallback capabilities, which may cause considerable signaling overhead in RRC signaling. Therefore, in some cases, especially when the UE radio access capability is restricted to be lower than the corresponding CA configuration defined in the 3GPP standard, the signaling overhead in CA communication can be significantly reduced.

[0028] Figure 1 An example scenario 100 according to a solution of an embodiment of the present invention is shown. Scenario 100 involves at least one network node and a UE, which is part of a wireless communication network (e.g., an LTE network, a 5G / NR network, an IoT network, or a 6G network). Scenario 100 illustrates a current network architecture. A UE may be connected to a network side. The network side includes one or more network nodes.

[0029] In some embodiments, the UE may send multiple BC-level capability signaling to the network node. The capability signaling for each aggregate bandwidth may indicate the maximum aggregate bandwidth across CCs. The UE may send FSPC-level capability signaling (FSPC) to the network node. The FSPC includes the channel bandwidth. The network node may determine a channel bandwidth configuration set based on the capability signaling for the multiple aggregate bandwidths and the FSPC. The network node may configure the UE's channel bandwidth configuration set and communicate with the UE based on the channel bandwidth configuration set.

[0030] In some embodiments, capability signaling of multiple aggregate bandwidths and FSPC may be used for downlink (DL) communications. The capability signaling of multiple aggregate bandwidths includes: (1) capability signaling of an FDD aggregate bandwidth indicating a maximum aggregate bandwidth among multiple maximum aggregate bandwidths across frequency division duplexing (FDD) CCs; and (2) capability signaling of a TDD aggregate bandwidth indicating a maximum aggregate bandwidth among multiple maximum aggregate bandwidths across time division duplexing (TDD) CCs.

[0031] For example, reference Figure 2, shows an example scenario 200 of a solution according to an embodiment of the present invention. Regarding DL CA of channels n25, n41, and n66, there are: (a) BC-level parameters; and (b) FSPC-level parameters. In the BC-level part, the parameters include: (1) bandwidth combination set (BCS) indicating support for bandwidth combination sets #0 (zeroth) and #5 (fifth); (2) channel n25 bandwidth class BWClassDL indicating A; (3) channel n41 bandwidth class BWClassDL indicating A; (4) channel n66 bandwidth class BWClassDL indicating A; (5) FDD aggregate bandwidth capability signaling AggBW-FDD-DL indicating the maximum aggregate bandwidth supported across FDD downlink CCs of 40MHz; and (6) TDD aggregate bandwidth capability signaling AggBW-TDD-DL indicating the maximum aggregate bandwidth supported across TDD downlink CCs of 100MHz. At the FSPC level, the capability parameters include: (1) channel bandwidth CBW 45 MHz for channel n25; (2) channel bandwidth CBW 100 MHz for channel n41; and (3) channel bandwidth CBW 45 MHz for channel n66.

[0032] Therefore, after receiving the BC-level capability parameters and the FSPC-level parameters from the UE, the network node determines that the channel bandwidth configuration set includes a bandwidth of 20 MHz for channel n25 (FDD channel), a bandwidth of 100 MHz for channel n41 (TDD channel), and a bandwidth of 20 MHz for channel n66 (FDD channel), provided that the following requirements are met: (1) the total FDD bandwidth (i.e., 20 MHz for aggregated channel n25 and 20 MHz for channel n66) should be less than or equal to the maximum supported aggregate FDD bandwidth of 40 MHz (indicated by the FDD aggregate bandwidth capability signaling AggBW-FDD-DL); and (2) the total TDD bandwidth (i.e., 100 MHz for channel n41) should be less than or equal to the maximum supported aggregate TDD bandwidth of 100 MHz (indicated by the TDD aggregate bandwidth capability signaling AggBW-TDD-DL). The network node and the UE perform CA communication based on the channel bandwidth configuration set.

[0033] In some embodiments, capability signaling of multiple aggregate bandwidths and FSPC may be used for DL ​​communication. The capability signaling of multiple aggregate bandwidths includes: (1) capability signaling of an FDD aggregate bandwidth indicating the maximum aggregate bandwidth among multiple maximum aggregate bandwidths across FDD CCs; (2) capability signaling of a TDD aggregate bandwidth indicating the maximum aggregate bandwidth among multiple maximum aggregate bandwidths across TDD CCs; and (3) capability signaling of a total aggregate bandwidth indicating the maximum total aggregate bandwidth among multiple maximum aggregate bandwidths across all CCs.

[0034] For example, reference Figure 3 , shows an example scenario 300 of a solution according to an embodiment of the present invention. Regarding DL CA of channels n25, n41, and n66, there are: (a) BC-level parameters; and (b) FSPC-level parameters. In the BC-level part, the parameters include: (1) bandwidth combination set BCS indicates support for bandwidth combination sets #0 (zeroth) and #5 (fifth); (2) channel n25 bandwidth class BWClassDL indicates A; (3) channel n41 bandwidth class BWClassDL indicates A; (4) channel n66 bandwidth class BWClassDL indicates A; (5) total aggregate bandwidth capability signaling AggBW-total-DL indicates the maximum total aggregate bandwidth supported across all CCs of 140MHz; and (6) FDD aggregate bandwidth capability signaling AggBW-FDD-DL indicates the maximum aggregate bandwidth supported across CCs of 80MHz; (7) TDD aggregate bandwidth capability signaling AggBW-TDD-DL indicates the maximum aggregate TDD bandwidth supported across CCs of 80MHz. At the FSPC level, the capability parameters include: (1) channel bandwidth CBW 45 MHz for channel n25; (2) channel bandwidth CBW 100 MHz for channel n41; and (3) channel bandwidth CBW 40 MHz for channel n66.

[0035] Therefore, after receiving the BC-level capability parameters and the FSPC-level parameters from the UE, the following requirements are met: (1) the total FDD bandwidth (i.e., 20 MHz of aggregated channel n25 and 40 MHz of channel n66) should be less than or equal to the maximum supported aggregate FDD bandwidth of 80 MHz (indicated by the FDD aggregate bandwidth capability signaling AggBW-FDD-DL); (2) the total TDD bandwidth (i.e., 80 MHz of channel n41) should be less than or equal to the maximum supported aggregate TDD bandwidth of 80 MHz (indicated by the TDD aggregate bandwidth capability signaling (AggBW-TDD-DL indication); and (3) the total bandwidth (i.e., 20 MHz for aggregated channel n25, 80 MHz for channel n41, and 40 MHz for channel n66) should be less than or equal to the maximum supported total aggregate bandwidth of 140 MHz (indicated by the total aggregate bandwidth capability signaling AggBW-total-DL), the network node determines that the channel bandwidth configuration set includes a bandwidth of 20 MHz for channel n25 (FDD channel), a bandwidth of 80 MHz for channel n41 (TDD channel), and a bandwidth of 40 MHz for channel n66 (FDD channel). The network node and the UE perform CA communication based on the channel bandwidth configuration set.

[0036] With the present invention, aggregated FDD bandwidth and aggregated TDD bandwidth pairs can be implicitly derived from the aggregated bandwidth signaling. Some pairs may be supported, but some pairs may not be supported. Refer to the following table as an example. In this example, the maximum total aggregate bandwidth supported is 140 MHz, and there are six pairs of aggregated FDD bandwidth and aggregated TDD bandwidth. Of these six pairs of aggregated FDD bandwidth and aggregated TDD bandwidth, the first, second, and sixth pairs are not supported because: (1) in the first pair, the TDD bandwidth of 100 MHz exceeds the maximum supported aggregate TDD bandwidth of 80 MHz; (2) in the second pair, the TDD bandwidth of 90 MHz exceeds the maximum supported aggregate TDD bandwidth of 80 MHz; and (3) in the sixth pair, the FDD bandwidth of 90 MHz exceeds the maximum supported aggregate FDD bandwidth of 80 MHz.

[0037]

[0038]

[0039] In some embodiments, capability signaling and FSPC for multiple aggregate bandwidths may be used for DL ​​communication. The capability signaling for multiple aggregate bandwidths includes: (1) capability signaling for an FDD aggregate bandwidth indicating the maximum aggregate bandwidth among multiple maximum aggregate bandwidths across FDD CCs; (2) capability signaling for a TDD aggregate bandwidth indicating the maximum aggregate bandwidth among multiple maximum aggregate bandwidths across TDD CCs; and (3) capability signaling for a total aggregate bandwidth indicating the maximum total aggregate bandwidth among multiple maximum aggregate bandwidths across all CCs; and (4) multi-input multi-output (MIMO) capability signaling indicating the maximum number of spatial multiplexing layers. It should be noted that the maximum number of spatial multiplexing layers may be a parameter (e.g., maxNumberMIMO-LayersPDSCH defined in the 3GPP standard) indicating the maximum number of spatial multiplexing layers for DL ​​reception supported by the user equipment.

[0040] For example, reference Figure 4, shows an example scenario 400 of a solution according to an embodiment of the present invention. Regarding DL CA of channels n25, n41, and n66, there are: (a) parameters at the BC level; and (b) parameters at the FSPC level. At the BC level, the parameters include: (1) bandwidth combination set BCS indicates support for bandwidth combination sets #0 (zeroth) and #5 (fifth); (2) channel n25 bandwidth class BWClassDL indicates A; (3) channel n41 bandwidth class BWClassDL indicates A; (4) channel n66 bandwidth class BWClassDL indicates A; (5) total aggregate bandwidth capability signaling AggBW-total-DL indicates the maximum total aggregate bandwidth supported across CCs of 140MHz; and (6) FDD aggregate bandwidth capability signaling AggBW-FDD-DL indicates the maximum aggregate bandwidth supported across FDD CCs of 80MHz; (7) TDD aggregate bandwidth capability signaling AggBW-TDD-DL indicates the maximum aggregate TDD bandwidth supported across TDD CCs of 80MHz; (8) MIMO capability signaling MIMO-DL indicates the maximum number of spatial multiplexing layers of 6. At the FSPC level, the capability parameters include: (1) channel bandwidth CBW 45 MHz and MIMO indication spatial multiplexing layer number 2 for channel n25; (2) channel bandwidth CBW 80 MHz and MIMO indication spatial multiplexing layer number 4 for channel n41; and (3) channel bandwidth CBW 40 MHz and MIMO indication spatial multiplexing layer number 2 for channel n66.

[0041] Therefore, after receiving the BC-level capability parameters and the FSPC-level parameters from the UE, the following requirements are met: (1) the total FDD bandwidth (i.e., 20 MHz for aggregated channel n25 and 40 MHz for channel n66) should be less than or equal to the maximum supported aggregate FDD bandwidth of 80 MHz (indicated by the FDD aggregate bandwidth capability signaling AggBW-FDD-DL); (2) the total TDD bandwidth (i.e., 80 MHz for channel n41) should be less than or equal to the maximum supported aggregate TDD bandwidth of 80 MHz (indicated by the TDD aggregate bandwidth capability signaling AggBW-TDD-DL); and (3) the total bandwidth (i.e., 20 MHz for aggregated channel n25, 80 MHz for channel n41, and 40 MHz for channel n66) should be less than or equal to the maximum supported aggregate TDD bandwidth of 80 MHz (indicated by the TDD aggregate bandwidth capability signaling AggBW-TDD-DL). Based on the maximum supported total aggregate bandwidth of 140 MHz (indicated by the capability signaling AggBW-total-DL of the total aggregate bandwidth), and (4) the total number of spatial multiplexing layers (i.e., the number of spatial multiplexing layers of 2 for MIMO indicator channel n25, the number of spatial multiplexing layers of 2 for MIMO indicator channel n41, and the number of spatial multiplexing layers of 2 for MIMO indicator channel n66) should be less than or equal to the maximum supported number of spatial multiplexing layers of 6 (indicated by the capability signaling MIMO-DL of MIMO), the network node determines that the channel bandwidth configuration set includes a bandwidth of 20 MHz and a number of spatial multiplexing layers of 2 for channel n25 (FDD channel), a bandwidth of 80 MHz and a number of spatial multiplexing layers of 2 for channel n41 (TDD channel), and a bandwidth of 40 MHz and a number of spatial multiplexing layers of 2 for channel n66 (FDD channel). The network node and the UE perform CA communication based on the channel bandwidth configuration set.

[0042] In some embodiments, capability signaling of multiple aggregate bandwidths and FSPC may be used for uplink communication. The capability signaling of multiple aggregate bandwidths includes: (1) capability signaling of an FDD aggregate bandwidth indicating the maximum aggregate bandwidth among multiple maximum aggregate bandwidths across FDD CCs; and (2) capability signaling of a TDD aggregate bandwidth indicating the maximum aggregate bandwidth among multiple maximum aggregate bandwidths across TDD CCs.

[0043] For example, reference Figure 5, shows an example scenario 500 of a solution according to an embodiment of the present invention. Regarding UL CA of channels n25, n41, and n66, there are: (a) BC-level parameters; and (b) FSPC-level parameters. In the BC-level part, the parameters include: (1) bandwidth combination set BCS indicating support for bandwidth combination sets #0 (zeroth) and #5 (fifth); (2) channel n25 bandwidth class BWClassUL indicating A; (3) channel n41 bandwidth class BWClassUL indicating A; (4) channel n66 bandwidth class BWClassUL indicating A; (5) FDD aggregate bandwidth capability signaling AggBW-FDD-UL indicating the maximum aggregate bandwidth supported across FDD CCs of 40MHz; and (6) TDD aggregate bandwidth capability signaling AggBW-TDD-UL indicating the maximum aggregate TDD bandwidth supported across TDD CCs of 90MHz. At the FSPC level, the parameters include: (1) channel bandwidth CBW 40 MHz for channel n25; (2) channel bandwidth CBW 90 MHz for channel n41; and (3) channel bandwidth CBW 40 MHz for channel n66.

[0044] Therefore, after receiving the BC-level capability parameters and the FSPC-level parameters from the UE, the network node determines that the channel bandwidth configuration set includes a bandwidth of 20 MHz for channel n25 (FDD channel), a bandwidth of 90 MHz for channel n41 (TDD channel), and a bandwidth of 20 MHz for channel n66 (FDD channel), provided that the following requirements are met: (1) the total FDD bandwidth (i.e., 20 MHz for aggregated channel n25 and 20 MHz for channel n66) should be less than or equal to the maximum supported aggregate FDD bandwidth of 40 MHz (indicated by the FDD aggregate bandwidth capability signaling AggBW-FDD-UL); and (2) the total TDD bandwidth (i.e., 90 MHz for channel n41) should be less than or equal to the maximum supported aggregate TDD bandwidth of 90 MHz (indicated by the TDD aggregate bandwidth capability signaling AggBW-TDD-UL). The network node and the UE perform CA communication based on the channel bandwidth configuration set.

[0045] In some embodiments, capability signaling of multiple aggregate bandwidths and FSPC may be used for UL communication. The capability signaling of multiple aggregate bandwidths includes: (1) capability signaling of an FDD aggregate bandwidth indicating a maximum aggregate bandwidth among multiple maximum aggregate bandwidths across FDD CCs; (2) capability signaling of a TDD aggregate bandwidth indicating a maximum aggregate bandwidth among multiple maximum aggregate bandwidths across TDD CCs; and (3) capability signaling of a total aggregate bandwidth indicating a maximum total aggregate bandwidth among multiple maximum aggregate bandwidths across all CCs.

[0046] For example, reference Figure 6, shows an example scenario 600 of a solution according to an embodiment of the present invention. Regarding UL CA of channels n25, n41, and n66, there are: (a) BC-level parameters; and (b) FSPC-level parameters. In the BC-level part, the parameters include: (1) bandwidth combination set BCS indicates support for bandwidth combination sets #0 (zeroth) and #5 (fifth); (2) channel n25 bandwidth class BWClassUL indicates A; (3) channel n41 bandwidth class BWClassUL indicates A; (4) channel n66 bandwidth class BWClassUL indicates A; (5) total aggregate bandwidth capability signaling AggBW-total-UL indicates the maximum total aggregate bandwidth supported across all CCs of 120MHz; and (6) FDD aggregate bandwidth capability signaling AggBW-FDD-UL indicates the maximum aggregate bandwidth supported across CCs of 80MHz; (7) TDD aggregate bandwidth capability signaling AggBW-TDD-UL indicates the maximum aggregate TDD bandwidth supported across CCs of 60MHz. At the FSPC level, the parameters include: (1) channel bandwidth CBW 45 MHz for channel n25; (2) channel bandwidth CBW 80 MHz for channel n41; and (3) channel bandwidth CBW 40 MHz for channel n66.

[0047] Therefore, after receiving the BC level capability parameters and FSPC level parameters from the UE, under the condition that the following requirements are met: (1) the total FDD bandwidth (i.e., 40 MHz of aggregated channel n25 and 20 MHz of channel n66) should be less than or equal to the maximum supported aggregate FDD bandwidth of 80 MHz (indicated by the FDD aggregate bandwidth capability signaling AggBW-FDD-UL); (2) the total TDD bandwidth (i.e., 60 MHz of channel n41) should be less than or equal to the maximum supported aggregate TDD bandwidth of 60 MHz (indicated by the TDD aggregate bandwidth capability signaling (AggBW-TDD-UL indication); and (3) the total bandwidth (i.e., 40 MHz for aggregated channel n25, 60 MHz for channel n41, and 20 MHz for channel n66) should be less than or equal to the maximum supported total aggregate bandwidth of 120 MHz (indicated by the total aggregate bandwidth capability signaling AggBW-total-UL), the network node determines that the channel bandwidth configuration set includes a bandwidth of 40 MHz for channel n25 (FDD channel), a bandwidth of 60 MHz for channel n41 (TDD channel), and a bandwidth of 20 MHz for channel n66 (FDD channel). The network node and the UE perform CA communication based on the channel bandwidth configuration set.

[0048] In some embodiments, capability signaling of multiple aggregate bandwidths and FSPC may be used for UL communication. The capability signaling of multiple aggregate bandwidths includes: (1) capability signaling of an FDD aggregate bandwidth indicating the maximum aggregate bandwidth among multiple maximum aggregate bandwidths across FDD CCs; (2) capability signaling of a TDD aggregate bandwidth indicating the maximum aggregate bandwidth among multiple maximum aggregate bandwidths across TDD CCs; and (3) capability signaling of a total aggregate bandwidth indicating the maximum total aggregate bandwidth among multiple maximum aggregate bandwidths across all CCs; and (4) MIMO capability signaling indicating the maximum number of spatial multiplexing layers.

[0049] For example, reference Figure 7 , shows an example scenario 700 of a solution according to an embodiment of the present invention. Regarding UL CA of channels n25, n41, and n66, there are: (a) BC level parameters; and (b) FSPC level parameters. At the BC level, the parameters include: (1) bandwidth combination set BCS indicates support for bandwidth combination sets #0 (zeroth) and #5 (fifth); (2) channel n25 bandwidth class BWClassUL indicates A; (3) channel n41 bandwidth class BWClassUL indicates A; (4) channel n66 bandwidth class BWClassUL indicates A; (5) total aggregate bandwidth capability signaling AggBW-total-UL indicates the maximum total aggregate bandwidth supported across all CCs is 140MHz; and (6) FDD aggregate bandwidth capability signaling AggBW-FDD-UL indicates the maximum aggregate bandwidth supported across FDD uplink CCs is 90MHz; (7) TDD aggregate bandwidth capability signaling AggBW-TDD-UL indicates the maximum aggregate TDD bandwidth supported across TDD uplink CCs is 70MHz; (8) MIMO capability signaling MIMO-UL indicates the maximum number of spatial multiplexing layers across CCs is 8. At the FSPC level, the parameters include: (1) channel bandwidth CBW 45 MHz and MIMO indication spatial multiplexing layer number 4 for channel n25; (2) channel bandwidth CBW 80 MHz and MIMO indication spatial multiplexing layer number 4 for channel n41; and (3) channel bandwidth CBW 40 MHz and MIMO indication spatial multiplexing layer number 2 for channel n66.

[0050] Therefore, after receiving the BC level capability parameters and the FSPC level parameters from the UE, the following requirements are met: (1) the total FDD bandwidth (i.e., 40 MHz for aggregated channel n25 and 30 MHz for channel n66) should be less than or equal to the maximum supported aggregate FDD bandwidth of 90 MHz (indicated by the FDD aggregate bandwidth capability signaling AggBW-FDD-UL); (2) the total TDD bandwidth (i.e., 70 MHz for channel n41) should be less than or equal to the maximum supported aggregate TDD bandwidth of 70 MHz (indicated by the TDD aggregate bandwidth capability signaling AggBW-TDD-UL); and (3) the total bandwidth (i.e., 40 MHz for aggregated channel n25, 70 MHz for channel n41, and 30 MHz for channel n66) should be less than or equal to the maximum supported aggregate TDD bandwidth of 90 MHz (indicated by the TDD aggregate bandwidth capability signaling AggBW-TDD-UL). Based on the maximum supported total aggregate bandwidth of 140 MHz (indicated by the capability signaling AggBW-total-UL of the total aggregate bandwidth), and (4) the total number of spatial multiplexing layers (i.e., the number of spatial multiplexing layers of 2 for MIMO indicator channel n25, the number of spatial multiplexing layers of 4 for MIMO indicator channel n41, and the number of spatial multiplexing layers of 2 for MIMO indicator channel n66) should be less than or equal to the maximum supported number of spatial multiplexing layers of 8 (indicated by the capability signaling MIMO-UL of MIMO), the network node determines that the channel bandwidth configuration set includes a bandwidth of 40 MHz and a number of spatial multiplexing layers of 2 for channel n25 (FDD channel), a bandwidth of 70 MHz and a number of spatial multiplexing layers of 4 for channel n41 (TDD channel), and a bandwidth of 30 MHz and a number of spatial multiplexing layers of 2 for channel n66 (FDD channel). The network node and the UE perform CA communication based on the channel bandwidth configuration set.

[0051] It should be noted that some of the BC level and FSPC level parameters mentioned in the above paragraphs have been defined in the 3GPP standard, such as bandwidth combination set BCS, CA bandwidth class BWClassDL, bandwidth class BWClassUL and channel bandwidth CBW, and therefore will not be further described in the present invention.

[0093] Supplementary Notes

[0094] The subject matter described in the present invention sometimes illustrates different components included in or connected to different other components. It is to be understood that these architectures described are merely examples, and in fact, many other architectures for realizing the same function can be implemented. In a conceptual sense, any component arrangement for realizing the same function is effectively "associated" so as to realize the desired function. Therefore, any two components that are combined to realize a specific function in the present invention can be considered to be "associated" to each other so as to realize the desired function, regardless of the architecture or intermediate components. Similarly, any two components so associated can also be considered to be "operably connected" or "operably coupled" to realize the desired function, and any two components that can be so associated can also be considered to be "operably coupled" to realize the desired function. The specific example of operable coupling includes but is not limited to physically pairable and / or physically interactive components and / or wirelessly interactive and / or wirelessly interactive components and / or logically interactive and / or logically interactive components.

[0095] In addition, with respect to the use of substantially any plural and / or singular terms in the present invention, those skilled in the art can convert the plural to the singular and / or convert the singular to the plural to suit the context and / or application. For the sake of clarity, various singular / plural permutations may be explicitly set forth in the present invention.

[0096] Furthermore, it will be understood by those skilled in the art that, in general, the terms used in the present invention, and particularly in the appended claims (e.g., the bodies of the appended claims), are generally intended to be “open” terms, e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” etc. It will also be understood by those skilled in the art that if a specific number of claim recitations is intended, such intent will be explicitly stated in the claim, and in the absence of such a statement, such intent is not present. For example, to aid understanding, the following appended claims may include the use of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of these phrases should not be construed as implying that the introduction of a claim recitation by the indefinite article “a” or “an” will limit any particular claim that includes the introduced claim recitation to embodiments that include only that one recitation, even when the claim includes the introductory phrases “one or more” or “at least one” and an indefinite article such as “a” or “an,” for example, “a” and / or “an” should be interpreted to mean “at least one” and “one or more,” and the same is true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, one skilled in the art will recognize that the recitation should be interpreted to mean at least the recited number, e.g., the mere recitation "two recitations" without other modifications means at least two recitations or two or more recitations. Furthermore, in those instances where a similar convention to "at least one of A, B, and C, etc." is used, generally, from the perspective of one skilled in the art will understand the convention, this construction contemplates that, for example, "a system having at least one of A, B, and C" will include but is not limited to systems having only A, only B, only C, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. In other instances where a similar convention to "at least one of A, B, or C, etc." is used, generally, from the perspective of one skilled in the art will understand the convention, this construction contemplates that, for example, "a system having at least one of A, B, or C" will include but is not limited to systems having only A, only B, only C, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. It will also be understood by those skilled in the art that any conjunction and / or phrase (whether in the specification, claims, or drawings) that actually represents two or more alternative terms should be understood to anticipate the possibility of including one, either, or both of the terms. For example, the phrase "A or B" will be understood to include the possibility of "A" or "B" or "A and B."

[0097] From the above, it should be understood that various embodiments of the present invention have been described herein for illustrative purposes, and various modifications may be made without departing from the scope and spirit of the present invention. Therefore, the various embodiments disclosed herein are not intended to be limiting, with the claims indicating the true scope and spirit.
