Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a method for information reporting, a communication device, and a storage medium. Background Art

[0002] In the process of reporting terminal capabilities, the UE still needs to independently indicate the specific band combinations supported and the corresponding FeatureSetCombinationID. As the number of band combinations supported by the UE increases, the size of the UE capability signaling also increases. At the same time, compared with 5G, in order to deploy more flexibly to adapt to more scenarios, 6G will support more networking types. For example, in 5G, for a band combination, the number of uplink carriers will not be greater than the number of downlink carriers, while in 6G, this limitation will be broken to adapt to more video upload services. This means that the number of band combinations that the UE needs to report will be more. If the current UE capability architecture is still used, it will have a certain impact on the overhead of UE capability signaling. Summary of the Invention

[0039] In the following, the embodiments of the present application will be described in conjunction with the accompanying drawings. The present application will be described below with reference to the accompanying drawings of the embodiments. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0040] In 3GPP, much is about how to reduce the signaling overhead of UE capability reporting. Especially after the introduction of carrier aggregation and multi-connection technologies, due to reporting the capabilities supporting carrier aggregation and multi-connection, the UE needs to report the corresponding band combination capabilities, thus greatly increasing the signaling overhead.

[0041] In 5G, in order to reduce such overhead, concepts such as FeatureSetCombination and FeatureSet are defined. As Figure 1 shown, Figure 1 is a 5G UE capability architecture diagram based on FeatureSetCombination provided in the prior art. Many band combinations with the same baseband or radio frequency capabilities can reuse the corresponding FeatureSetCombination, thus reducing the signaling overhead. However, even so, in the current UE capability reporting, the UE still needs to independently indicate the specific band combinations it supports and the corresponding FeatureSetCombinationID. As the number of band combinations supported by the UE increases, the size of the UE capability signaling also increases.

[0042] At the same time, compared with 5G, in order to be more flexible in deployment to adapt to more scenarios, 6G will support more networking types. For example, in 5G for a band combination, the number of uplink carriers will not be greater than the number of downlink carriers. In 6G, this limitation will be broken to adapt to more video upload services. This means that the number of band combinations the UE needs to report will be more. If the current UE capability architecture is still used, it will have a certain impact on the signaling overhead of UE capabilities.

[0043] Figure 2 is a decoupling schematic diagram of the uplink and downlink provided by the prior art. As Figure 2 shown, in order to meet more flexible uplink and downlink carrier pairing requirements, decoupling of the uplink and downlink needs to be done. For example, the uplink link pool and the downlink link pool are decoupled. The decoupling is mainly reflected in the following aspects:

[0044] There is no frequency band limit between the uplink carriers in the uplink link pool and the downlink carriers in the downlink link pool. The uplink carrier and the downlink carrier can be of the same frequency band or different frequency bands.

[0045] There is no limit between the number of uplink carriers in the uplink link pool and the number of downlink carriers in the downlink link pool. The number of uplink carriers can be greater than, less than, or equal to the number of downlink carriers.

[0046] There are no restrictions on the scheduling relationship and feedback relationship between the uplink carrier and the downlink carrier. Any downlink carrier can schedule any one or more uplink carriers, and any uplink carrier can feed back the feedback information of any one or more downlink carriers.

[0047] Based on the above, when the UE performs capability reporting, it is necessary to be able to flexibly indicate the uplink and downlink capabilities. However, in the current UE capability reporting architecture, for a frequency band combination, the uplink and downlink capabilities are coupled together, and in the current architecture, each uplink frequency band must have a corresponding downlink frequency band. However, in the design for future communications, the uplink frequency band does not necessarily have a corresponding downlink frequency band.

[0048] In one embodiment, Figure 3 is a flowchart of an information reporting method provided by an embodiment of the present application. This embodiment is applied to the case of decoupling the uplink and downlink capabilities. This embodiment can be executed by a first communication device. For example, the first communication device can be the terminal side (such as a UE). As Figure 3 shown, this embodiment includes: S110 - S130.

[0049] S110. Decouple the UE capabilities into an uplink capability set and a downlink capability set.

[0050] In one embodiment, the uplink capability set includes the relevant uplink capabilities in the UE capabilities; the downlink capability set includes the relevant downlink capabilities in the UE capabilities. In one example, the uplink capability set can include the relevant uplink capabilities of baseband processing and the relevant uplink capabilities of radio frequency processing in the UE; the downlink capability set can include the relevant downlink capabilities of baseband processing and the relevant downlink capabilities of radio frequency processing in the UE.

[0051] S120. Report the uplink capability set and the downlink capability set to a second communication device.

[0052] The first communication device separately reports the uplink capability set and the downlink capability set to the second communication device respectively to achieve the decoupling effect between the uplink capability set and the downlink capability set.

[0053] In one embodiment, the information reporting method applied to the first communication device further includes: reporting the decoupling combination criterion between the uplink capability set and the downlink capability set to the second communication device. The decoupling combination criterion refers to the usage configuration rules formulated for the uplink capability set and the downlink capability set. In the actual communication process, there are some similar attributes between the uplink capability set and the downlink capability set, that is, there are some capability elements with the same attributes. At this time, the uplink capability set and the downlink capability set cannot be arbitrarily matched, and corresponding usage configuration rules can be formulated for the uplink capability set and the downlink capability set. The corresponding usage configuration rules can be formulated according to the degree of decoupling.

[0054] In one embodiment, it further includes: dividing the frequency bands into corresponding uplink frequency band pools and downlink frequency band pools; reporting the maximum capabilities supported by each uplink frequency band pool and downlink frequency band pool. The first communication device can divide different uplink frequency bands into corresponding uplink frequency band pools according to the similarity of the frequency band capabilities, and divide different downlink frequency bands into corresponding downlink frequency band pools. In this way, the frequency band capabilities in the same frequency band pool will be the same or similar.

[0055] In one embodiment, each uplink frequency band pool corresponds to one or more uplink frequency band combination types; wherein, the uplink frequency band combination type is used to indicate the number of uplink frequency bands included in each uplink frequency band combination, and the number of carriers on each uplink frequency band;

The uplink frequency band combination type is used to indicate the number of uplink frequency bands included in the uplink frequency band combination, and the number of continuously aggregated carriers on each uplink frequency band; the downlink frequency band combination type is used to indicate the number of downlink frequency bands included in the downlink frequency band combination, and the number of continuously aggregated carriers on each downlink frequency band.

For the downlink frequency band combination type reported by the first communication device, it can also indicate that the first communication device can support any one of its lower-order or reduced-order downlink frequency band combination types, and correspondingly, support the maximum downlink frequency band capability corresponding to the lower-order or reduced-order downlink frequency band combination type.

[0063] In one embodiment, it further includes:

[0067] For downlink frequency bands in the downlink frequency band pool with capabilities stronger than those of the downlink frequency band pool, report the UE capabilities separately. If an uplink frequency band in a certain uplink frequency band pool has stronger capabilities than those in this uplink frequency band pool, it can also be reported separately to the second communication device; if a downlink frequency band in a certain downlink frequency band pool has stronger capabilities than those in this downlink frequency band pool, it can also be reported separately to the second communication device.

[0130] Figure 5 is a UE capability architecture diagram based on a band pool provided by an embodiment of the present application, as Figure 5As shown, different frequency bands are divided into multiple frequency band pools according to the similarity of their capabilities.

The first frequency band supports 1 carrier, the second frequency band supports 2 carriers, and the third frequency band supports 3 carriers. Then it can be represented in the way of {class A, class B, class C}. The number of class cells can be used to indicate the number of frequency bands in the supported frequency combination, and the class category can be used to indicate (for example, class A corresponds to 1 carrier, class B corresponds to 2 carriers, class C corresponds to 3 carriers, class D corresponds to 4 carriers).

[0133] The UE reports the frequency band combination type to report the corresponding UE capabilities. For example, for the UE to report a frequency band combination type such as {classA, class B, class C}, it also means that the UE can support any one of its fallback frequency band combination types, such as {class A}, {class B}, {class C}, {class A, class B}, {class A, classC}, {class B, class C}, etc.

[0134] The UE further indicates at least one of the following information in the reported frequency band combination type: same frequency band information, different frequency band information, continuous carrier aggregation information, discontinuous carrier aggregation information. For example, {class A, class B, class C} indicates that class A and class B are in the same frequency band, while Class C is in a different frequency band. The UE can also indicate how many different frequency bands are included in a frequency band combination type.

[0135] If the frequency bands in some frequency band pools have stronger capabilities than those in the pool, they can also be reported separately.

[0136] Furthermore, for different carrier combination types, the specific capabilities on each carrier can be indicated, such as bandwidth, etc. There are the following ways to indicate the specific capabilities on the carrier:

[0137] Method 1: Based on explicit indication, that is, for different carrier combination types, the specific capabilities on each of their frequency bands are indicated, such as bandwidth, number of transmit ports, number of receive ports, number of layers supporting MIMO, modulation and demodulation methods, etc. It should be noted that these capabilities include both uplink and downlink.

[0138] Method 2: Based on an implicit or a combination of implicit and explicit methods. For example, the maximum aggregated bandwidth, total number of transmit ports, total number of receive ports, maximum number of MIMO layers, highest modulation and demodulation method, etc. are indicated. For example, this indication method can have 3 different granularities.

[0139] For each frequency band type, at this time, the maximum aggregated bandwidth is the sum of the bandwidths supported by all carriers in this type, the total number of transmit and receive ports is the sum of the ports on all carriers, the maximum number of MIMO layers is the maximum number of MIMO layers supported by a single carrier or the aggregated MIMO layers supported by all carriers, and the highest modulation and demodulation method is the highest modulation and demodulation method supported by a single carrier.

[0140] For multiple carriers (such as consecutive carriers on a frequency band or the number of aggregated carriers): At this time, the maximum aggregated bandwidth, total transmit / receive ports, maximum number of MIMO layers, highest modulation and demodulation method, etc. can be defined under different classes (or different numbers of carriers).

[0141] For all frequency band types; at this time, the capability reporting is independent of the specific frequency band type, or rather, the capability limitations at this time apply to all frequency band types. The maximum aggregated bandwidth is the sum of the bandwidths supported by all carriers, the total number of transmit and receive ports is the sum of the ports on all carriers, the maximum number of MIMO layers is the maximum number of MIMO layers supported by a single carrier or the aggregated MIMO layers supported by all carriers, and the highest modulation and demodulation method is the highest modulation and demodulation method supported by a single carrier.

[0142] It should be noted that the indicated capabilities can all include both uplink and downlink. For example, the bandwidth includes uplink bandwidth and downlink bandwidth, the number of uplink MIMO layers and downlink MIMO layers, as well as the uplink modulation and demodulation method and the downlink modulation and demodulation method.

[0143] Among them, the frequency band combination type can also be replaced by the frequency band and carrier combination type, or the carrier combination type. The frequency band combination type can indicate the combination method of frequency bands in the frequency band, while the carrier combination type can indicate the combination method of carriers.

[0144] In the current UE capability reporting, it is mainly based on band combinations for reporting. In this way, the UE reports the corresponding capabilities for different band combinations. In practice, however, the UE capabilities reported on many adjacent frequency bands are actually very similar or even identical. That is to say, from the perspective of the UE's capability set 1 (such as radio frequency capabilities), it is mainly related to the frequency band range where it is located. As shown in Table 1, the 3GPP Radio Access Technology (RAT) in FR1 (frequency Range 1, 450 MHz - 6000 MHz, also known as sub6G) can be mainly divided into LB, MHB, and UHB, which are the Low band, Mid band, and High band in 3GPP terminology. Generally, a set of antennas is shared for 3.5 - 4.9 GHz, a set of antennas is shared for 1.7 - 2.7 GHz, and a set of antennas is shared for the Low band.

[0145] Table 1

[0146] LB MHB UHB Full Name Low Band Mid / High Band Ultra High Band Frequency Range 617MHz - 960MHz 1.7GHz - 2.7GHz 3.3GHz - 5GHz MIMO Requirement 2*2 2*2 or 4*4 4*4

[0147] Although the capabilities supported by the UE within the same frequency band range are similar or identical, the UE still needs to report the corresponding capabilities separately for each band or each band combination, resulting in excessive UE capability signaling overhead.

[0148] To facilitate the understanding of the solution provided in this application, the band combination types and the indication methods of specific capabilities will be described below in combination with specific embodiments.

[0149] Embodiment 1

[0150] This embodiment mainly describes the frequency band pool and the types of band and carrier combinations it supports

[0151] In the embodiment, the frequency band pool contains 3 bands, denoted as band 1, band 2, and band 3 respectively (or three carriers, namely carrier 1, carrier 2, and carrier 3). There are 3 types of carrier types corresponding to this pool, denoted as Class A_Class B_Class C, Class C_Class C, and Class D respectively. Figure 6 It is a schematic diagram of a frequency band pool and the types of band and carrier combinations it supports provided by an embodiment of this application. As Figure 6 shown, this represents that the UE supports the following band combinations (and their fallback combinations. The fallback combination is the combination left after deleting one or more carriers in this combination).

[0152] 3-band combination: Band 1 Class A_band 2 Class B_band 3 Class C, where band 1 / 2 / 3 can be exchanged arbitrarily, that is, it is not affected by the order of band numbers, that is, it can also support Band 2 Class A_band 1 Class B_band 3 Class C, etc.

[0153] 2-band combinations: Band 1 Class C_Band 2 Class C and Band 1 Class C_Band 3 Class C, and Band 1 2 Class C_Band 3 Class C.

[0154] 1-band combinations: Band 1 Class and Band 2 Class D and Band 3 Class D.

[0155] Embodiment 2

[0156] This embodiment mainly describes the frequency band and carrier combination type and the specific ability indication it supports. The specific ability indication in this embodiment is based on the displayed indication. That is, for different frequency band and carrier combination types, it indicates the abilities supported by each carrier in the frequency band and carrier combination type, as shown in Table 2.

[0157] Table 2

[0158]

[0159] The UE reports its corresponding capabilities for each CC in each carrier and frequency band combination, such as bandwidth, number of transmit ports, number of receive ports, or number of layers supporting MIMO, modulation and demodulation methods, etc.

[0160] Embodiment 3

[0161] This embodiment mainly describes the frequency band and carrier combination type and the specific ability indication it supports, including implicit, or a combination of implicit and explicit indications.

[0162] Based on implicit or a combination of implicit and explicit indications, that is, it indicates the maximum aggregation bandwidth, total number of transmit ports, total number of receive ports, maximum number of MIMO layers, highest modulation and demodulation method, etc., which can be indicated for a carrier unit or all carrier units. For a carrier unit, it means that the constraints cannot be exceeded on each carrier unit, while for all carrier units, it means that the sum of the capabilities on all carrier units cannot exceed this constraint.

[0163] This indication method can have 3 different granularities:

[0164] 1. For each carrier and band type;

[0165] 2. For multiple carriers (such as consecutive carriers on a frequency band or the number of aggregated carriers);

[0166] 3. For all carriers and band types.

[0167] For the first method, it is shown in Table 3.

[0168] Table 3

[0169]

[0170] For the second method, it is shown in Table 4.

[0171] Table 4

[0172]

[0173] For the third method, it is shown in Table 5.

[0174] Table 5

[0175]

[0176] In the above embodiments, the band combination type can also be implicitly indicated by its supported specific capabilities (i.e., no specific reporting is required). For example, in the first method, it can only include the band pool and its supported specific capabilities, and the type does not need to be specifically reported.

[0177] In the following embodiments, taking the first communication device as the UE, the second communication device as the network side, the first capability set as the baseband capability, and the second capability set as the radio frequency capability as an example, the independent reporting process of the baseband capability and the radio frequency capability is described.

[0178] The baseband capability is mainly reflected in the number of MIMO layers, the number of CCs, and the baseband bandwidth, etc.; while the radio frequency capability is mainly reflected in the number of CCs, the radio frequency bandwidth, and the power, etc. In order to achieve decoupling, the baseband capability and the radio frequency capability need to be reported separately, and then corresponding rules are formulated according to the degree of decoupling. The solution needs to include three parts: independent reporting of the baseband capability; independent reporting of the radio frequency capability; decoupling combination criteria for the baseband capability and the radio frequency capability.

[0179] The first part: The baseband capability includes the following three independent reporting methods:

[0180] Method 1: Report the maximum baseband capability index or capacity index, which is calculated by a formula. The input parameters of the formula can include the number of CCs, bandwidth (which can be the aggregated total bandwidth of all frequency bands, the aggregated total bandwidth of each frequency band, the bandwidth of each CC, etc.), the maximum number of MIMO layers (or the sum of MIMO layer numbers), and numerology, etc.

[0181] In one example, the UE can support any capability combination that is lower than or equal to this index.

[0182] This formula can be defined by the protocol or reported by the UE to the network side.

[0183] When the network side configures, it can calculate and configure according to the same formula to ensure that the configured capabilities do not exceed the capability index reported by the UE.

[0184] This maximum capability index or maximum capacity index may include multiple metrics, such as computing power, storage capacity / space, number of processes / threads, etc.

[0185] Method 2: Distributed metrics. For example, the UE reports one or more multi-dimensional capability groups (which can also be called baseband capability groups). Among them, each multi-dimensional capability group can include {the maximum number of supported CCs, the aggregated maximum bandwidth, the maximum MIMO layer (or the sum of MIMO layer numbers), numerology or numerology combination}. The network side selects one of the groups for configuration, as shown in Table 6.

[0186] Table 6

[0187]

[0188] Method 3: Display and report the maximum capability of each CC corresponding to different numbers of CCs.

[0189] The second part: Separate reporting of radio frequency capabilities: Radio frequency capabilities are related to frequency bands. The reporting method can refer to the above-mentioned reporting method based on the frequency band pool (i.e., Embodiment 1 to Embodiment 3). During the reporting process of the above frequency band pool, if only radio frequency-related capabilities are reported in "indicating the specific capabilities on each carrier for different frequency band combination types", then it can be regarded as the reporting of radio frequency capabilities. If it is a combination of baseband and radio frequency capabilities, it can be regarded as the unified reporting of radio frequency capabilities and baseband capabilities.

[0190] Part 3: Decoupling combination criteria between baseband capabilities and radio frequency capabilities. As can be seen above, there are some potential similar attributes between radio frequency capabilities and baseband capabilities. For example, in carrier aggregation, the impact on the baseband is reflected in the number of CCs, and the impact on the radio frequency may be mainly reflected in the number of CCs or the frequency block. In MIMO, the impact on the baseband is reflected in the maximum number of MIMO layers, and the impact on the radio frequency is mainly reflected in the total number of MIMO layers or the total number of antenna ports. Therefore, there is a certain associated part between baseband and radio frequency capabilities, which restricts that the baseband capabilities and radio frequency capabilities cannot be arbitrarily matched. For example, a radio frequency capability with two ports cannot match a baseband capability with 4 MIMO layers. Therefore, corresponding usage pairing rules need to be formulated for the independently reported baseband capabilities and radio frequency capabilities. In addition, for different frequency band ranges, such as low / mid / high frequencies, the aggregated bandwidth, the numerology used, the number of MIMO layers, etc. may also be different. Therefore, according to whether specific frequency bands are divided, there are the following two reporting methods:

[0191] Reporting method 1: Partial decoupling, that is, the UE reports the corresponding baseband capabilities for different frequency band pools or frequency ranges, but within the same frequency band pool or frequency range, the baseband capabilities are independent of the corresponding frequency bands. Further, the same as above, rules can be formulated for the usage pairing of radio frequency capabilities and baseband capabilities. Figure 7 It is a schematic diagram of the configuration of the constraint rules for frequency band capabilities and baseband capabilities in a partial decoupling scenario provided by an embodiment of the present application. As Figure 7 shown, within the same frequency band pool, the baseband capabilities and radio frequency capabilities are in one-to-one correspondence.

[0192] This rule can be reflected in two ways:

[0193] Method 1: Protocol constraints. For example, constraints are imposed from the number of CCs, bandwidth, MIMO layer / transceiving antenna ports, modulation and demodulation order, numerology, etc. For example,

[0194] Regarding the constraint rule for the maximum number of supported CCs, that is, from the radio frequency band combination type (or the number of CCs in the radio frequency capabilities) to the baseband capabilities, they need to match. For example:

[0195] If Class A_Class B_Class C is (6CC), then the corresponding baseband capabilities should include at least 6 carriers;

[0196] Regarding the bandwidth (Bandwidth) constraint rule, the final bandwidth is jointly determined according to the reports of baseband capabilities and radio frequency capabilities. For example, the baseband capabilities introduce corresponding factors to convert the radio frequency capabilities according to different numerologies.

[0197] For the constraint rules of the maximum MIMO layer, for example, if the corresponding antenna ports are 2 Rx, then the corresponding baseband capability can only be 2-layer MIMO.

[0198] For the constraint rules of modulation / demodulation method / Numerology, for example, when matching the RF capability with the corresponding baseband capability, the corresponding modulation / demodulation method / Numerology should be supported in the baseband capability.

[0199] Method 2: UE implicit indication, that is, the UE reports the adaptation constraints of the corresponding baseband capability and RF capability. For example, the UE can indicate different classification information of the supported capabilities. When the network configures the UE, it needs to comply with the constraint rules of these classification information. These classification information can be from the number of CCs, bandwidth, MIMO layer / number of transceiver antenna ports, modulation / demodulation order, and UE power class.

[0200] These classification information include both RF capabilities and baseband capabilities.

[0201] In an example, Figure 8 is a schematic diagram of the configuration of the classification information of the frequency band capability and the baseband capability in a partially decoupled scenario provided by an embodiment of the present application. In this example, the UE can report the classification information it supports, that is, Figure 8 the classification information (Category information) in, this information can be defined at the entire UE granularity or based on each band pool. The UE can report the supported category for each band pool. Category can be predefined by the protocol, and the UE only needs to report the Category number / identifier, or directly report the specific content of Category.

[0202] Method 3: UE explicit indication, that is, directly associate the baseband capability with the RF capability. For example, number the baseband capability, and then the RF capability is associated with each other by indicating the number of the baseband capability, as shown in Table 7.

[0203] Table 7

[0204] RF Capability Adaptable Baseband Capability Group 1 x, y 2 x, y, z …

[0205] Among them, x, y, z represent different baseband capabilities.

[0206] Note: In the above solutions, the classification information supported in different carriers / band groups / pools may be the same;

[0207] In the above figure, some elements of the baseband and radio frequency capabilities may be the same in different carriers / band groups / pools. Therefore, a baseband and radio frequency capability pool can also be defined, and then referenced through the Index scheme in each carrier / band group / pool.

[0208] In the above figure, each element of the baseband and radio frequency capabilities can include only the uplink, only the downlink, or both the uplink and the downlink.

[0209] Reporting method 2: Complete decoupling: That is, the UE reports baseband capabilities independent of the band, but the maximum capabilities of the baseband can be compatible with the maximum capabilities supported by the radio frequency, such as the number of CCs, MIMO layers, bandwidth, etc. Further, rules can be formulated for the pairing of the use of radio frequency capabilities and baseband capabilities, and these rules can be reflected in three ways similar to those in the above partial decoupling.

[0210] Figure 9 It is a schematic diagram of the configuration of the constraint rules between the band capabilities and the baseband capabilities in a completely decoupled scenario provided by an embodiment of the present application. As can be seen from the above description, when the UE reports the radio frequency capability group and the baseband capability group to the network side, for method 2, it will also report the supported classification constraints.

[0211] In one example, for the optimization of the carrier aggregation solution:

[0212] Figure 10 It is a schematic diagram of a carrier aggregation method for multi-spectrum native design provided by an embodiment of the present application. In the carrier aggregation diagram shown in Figure 10, multiple radio frequency carriers will first be aggregated into a large radio frequency carrier pool, and this large radio frequency carrier pool is further mapped into a baseband carrier. In this architecture, the UE needs to report the mapping relationship between the radio frequency capabilities and the carrier capabilities, for example: which radio frequency carriers can be aggregated into a radio frequency carrier pool, and the baseband carrier capabilities that each radio frequency carrier pool can map to. Since in the current UE capability architecture, the radio frequency capabilities and the baseband capabilities are coupled together, this architecture where multiple radio frequency carriers are mapped to one baseband carrier cannot be supported.

[0213] Figure 11 It is a schematic diagram of the configuration of the constraint rules between the baseband capabilities and the radio frequency capabilities provided by an embodiment of the present application. As Figure 11 shown, a similar technology is adopted in this architecture, that is, multiple radio frequency capabilities are mapped to one baseband capability according to certain constraint rules. Among them, the constraint rules are similar to the above three ways.

[0214] In this architecture, the UE will report a group of radio frequency capabilities, a group of baseband capabilities, and the mapping relationship between the radio frequency capabilities and the baseband capabilities, and this mapping relationship can be in the three ways described above.

[0215] The reporting can be based on a frequency band pool or based on the entire UE.

[0216] In the following embodiments, taking the first communication device as the UE and the second communication device as the network side as an example, the decoupled reporting process of uplink and downlink capabilities is described. Among them, the uplink capability set can also be simply referred to as uplink capability; the downlink capability set can also be simply referred to as downlink capability.

[0217] To achieve decoupling, the uplink capability and the downlink capability need to be reported separately, and then corresponding rules are formulated according to the degree of decoupling. The solution for decoupled uplink and downlink reporting includes three parts: independent reporting of uplink capabilities; independent reporting of downlink capabilities; combination criteria after uplink and downlink decoupling (i.e., decoupled combination criteria).

[0218] Here, according to whether the radio frequency and baseband capabilities are decoupled as above, it can be further divided into two categories for discussion: decoupling of radio frequency capabilities and baseband capabilities; non - decoupling of radio frequency capabilities and baseband capabilities.

[0219] Figure 12 is a schematic diagram of uplink and downlink capability reporting in a scenario where baseband capabilities and radio frequency capabilities are decoupled provided by an embodiment of the present application, as Figure 12 shown:

[0220] 1) In the above Figure 12 , there can be only one downlink frequency band pool (DL band pool), and there can also be only one uplink frequency band pool (UL band pool), and these two pools can also be the same one.

[0221] 2) Additionally, different frequency band pools (band pool) can also have corresponding different uplink and downlink radio frequency capabilities. This logic is similar to the previous description and will not be elaborated here.

[0222] Figure 13 is a schematic diagram of the implementation of decoupled uplink and downlink reporting of baseband capabilities provided by an embodiment of the present application. As Figure 13 shown, for the decoupled uplink and downlink of baseband capabilities: when implemented in the baseband, the uplink capability and the downlink capability are generally independently implemented, and there may not be an inherent constraint between the uplink and downlink capabilities. To achieve sharing of resources such as storage and computing power between the uplink and downlink, the computing power values of the uplink and downlink (i.e., uplink computing power constraint information or downlink computing power constraint information) or the total storage requirement may be restricted within a certain range.

[0223] This constraint can be described by a protocol or indicated by the UE. The UE indication can consider the following three constraint methods:

[0224] The total computing power constraint information, i.e., the total uplink and downlink computing power. Similar to the above, report the maximum baseband power index or the maximum capacity index, which is calculated by a formula. The input parameters of the formula can include the number of CCs, bandwidth (which can be the aggregated total bandwidth, the aggregated total bandwidth on each band, the bandwidth on each CC, etc.), the maximum number of MIMO layers (or the sum of MIMO layer numbers), numerology, etc.

[0225] UEs can support any combination of capabilities that are lower than or equal to this index; this formula can be defined by the protocol or reported by the UE to the network side; when the network side configures, it can calculate and configure according to the same formula to ensure that the configured capabilities do not exceed the capability index reported by the UE; this maximum power index or maximum capacity index may include multiple output metrics, such as computing power, storage capacity / space, number of processes / threads, etc.

[0226] UEs report their classification constraints. For example, UEs report the supported category, and this classification information includes both uplink information and downlink information.

[0227] Display indication, that is, display which uplink capabilities and which downlink capabilities can be matched, as shown in Table 8.

[0228] Table 8

[0229] Downlink Capability Adaptable Uplink Capability Group 1 x, y 2 x, y, z …

[0230] For the uplink and downlink decoupling of radio frequency capabilities: Since in the design of radio frequency chips, the uplink and downlink cannot be as completely independent as baseband chips, there is some coupling. There are the following ways:

[0231] Figure 14 It is a schematic diagram of the configuration of radio frequency capabilities with the same frequency band pool provided by an embodiment of this application. As Figure 14 shown, similar to the previous, frequency bands or carriers with similar attributes can be placed in a frequency band carrier group, which means that within this frequency band carrier group, the uplink and downlink can be matched.

[0232] Figure 15 It is a schematic diagram of the configuration of radio frequency capabilities with different frequency band pools provided by an embodiment of this application. As Figure 15 shown, for some bands, if they only support downlink or uplink carriers, at this time, the frequency band carrier groups supporting the uplink may be inconsistent with those supporting the downlink. One or more independent uplink carrier groups, one or more downlink carrier groups, and the corresponding coupling relationships can be defined.

[0233] In the above description, the constraints between the uplink and downlink frequency band carrier pools can be in the following ways:

[0234] (1) Meet the protocol definition, that is, only the uplink and downlink frequency band carrier pools defined in the protocol can be combined;

[0235] (2) The uplink and downlink carrier pools shall at least contain the same frequency band or carrier / frequency range (TDD);

[0236] (3) Display indication, for example, indicating which downlink frequency band carrier pools can be paired with which uplink frequency band carrier pools;

[0237] In the above description, the constraints between the uplink and downlink radio frequency capabilities can be in the following ways:

[0238] (1) The UE indicates the category it supports, and the category information includes the supported uplink and downlink carrier / band combination types, uplink (number of CCs, MIMO layer or transmit antenna ports, number of spectrum blocks, uplink bandwidth, modulation and demodulation method) capabilities, downlink (number of CCs, MIMO layer or transmit antenna ports, number of spectrum blocks, uplink bandwidth, modulation and demodulation method) capabilities, etc.

[0239] (2) Total computing power constraint. Since in the radio frequency capabilities, a part is determined by the radio frequency chip capabilities, the computing power of the radio frequency chip capabilities can be designed similar to the baseband capabilities to constrain the total computing power of the uplink and downlink.

[0240] (3) Display indication, for example, indicating which downlink radio frequency capabilities can be paired with which uplink radio frequency capabilities.

[0241] Figure 16 It is a schematic diagram of the uplink and downlink capability reporting in the scenario where the baseband capabilities and radio frequency capabilities are not decoupled provided by the embodiments of the present application. In the scenario where the baseband capabilities and radio frequency capabilities are not decoupled, the uplink and downlink capability reporting process is as Figure 16 shown.

[0242] In this architecture, the constraints between the uplink and downlink frequency band carrier pools are the same as above, and the reporting method of the constraints between the uplink and downlink frequency band carrier pools is also similar to before. The difference is only that at this time, the baseband capabilities and radio frequency capabilities are coupled together, that is, the corresponding three methods are as follows:

[0243] (1) The UE indicates the category it supports, and the category information includes the supported uplink and downlink carrier / band combination types, uplink (number of CCs, MIMO layer or transmit antenna ports, number of spectrum blocks, uplink bandwidth, modulation and demodulation method) radio frequency baseband capabilities, downlink (number of CCs, MIMO layer or transmit antenna ports, number of spectrum blocks, uplink bandwidth, modulation and demodulation method) radio frequency baseband capabilities, etc.

[0244] (2) Total computing power constraint, including baseband computing power, radio frequency computing power, or the sum of the two.

[0245] (3) Display an indication, such as an indication of which downlink radio frequency capabilities can be paired with which uplink radio frequency capabilities.

[0246] In one embodiment, Figure 17 is a structural block diagram of an information reporting device provided by an embodiment of the present application. This embodiment is applied to a first communication device. As Figure 17 shown, the information reporting device in this embodiment includes: a decoupler 310 and a transmitter 320.
