Method for reporting UE capability, electronic device and storage medium

[0001] Cross-reference to related applications

[0002] The present disclosure is based on Chinese Patent Application No. CN202411073439.7 entitled "Method for reporting UE capability, electronic device and storage medium" filed on August 6, 2024, and claims priority to the same, the disclosure of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present disclosure relates to the technical field of communication, and in particular to a method for reporting user equipment (UE) capability, an electronic device and a storage medium. BACKGROUND

[0004] In the reporting process of terminal capability, the UE still needs to independently indicate the supported specific band combination and the corresponding FeatureSetCombinationID. With the increase of the band combination supported by the UE, the size of the UE capability signaling is also increasing. 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, the number of uplink carriers for a band combination will not be greater than the number of downlink carriers, but in 6G, this limitation will be broken to adapt to more video upload businesses. This means that the number of band combinations to be reported by the UE will be more, and if the current UE capability architecture is still used, the overhead of the UE capability signaling will be impacted.

[0042] Embodiments of the present disclosure will be described below with reference to the accompanying drawings. The present disclosure is described below with reference to the accompanying drawings, and the examples are only used to explain the present disclosure, and are not used to limit the scope of the present disclosure.

[0043] In 3GPP, many are about how to reduce the signaling overhead of UE capability reporting, especially after the introduction of carrier aggregation and multi-connection technology, because of the reporting of support carrier aggregation and multi-connection capabilities, the UE needs to report the corresponding frequency band combination capability, thereby greatly increasing the signaling overhead.

[0044] In 5G, in order to reduce such overhead, the concepts of FeatureSetCombination, FeatureSet, etc. are defined, as shown in FIG. 1, which is a 5G UE capability architecture based on FeatureSetCombination provided in the prior art. Many frequency band combinations with the same baseband or radio frequency capability can reuse the corresponding FeatureSetCombination, thereby reducing the signaling overhead. However, even so, in the current UE capability reporting, the UE still needs to independently indicate the specific frequency band combination supported and the corresponding FeatureSetCombinationID, and with the increase of the frequency band combination supported by the UE, the size of the UE capability signaling is also increasing.

[0045] 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, the number of uplink carriers for a frequency band combination will not be greater than the number of downlink carriers, but in 6G, this limitation will be broken to adapt to more video upload businesses. This means that the number of frequency band combinations that the UE needs to report will be more, and if the current UE capability architecture is still used, the overhead of the UE capability signaling will be impacted to a certain extent.

[0046] FIG. 2 is a decoupling diagram of uplink and downlink provided in the prior art. As shown in FIG. 2, in order to meet the more flexible uplink and downlink carrier pairing requirements, uplink and downlink decoupling needs to be decoupled, for example, the uplink pool and the downlink pool are decoupled. The decoupling here mainly reflects the following aspects:

[0047] There is no frequency range restriction between the uplink carriers in the uplink pool and the downlink carriers in the downlink pool. The uplink carriers and the downlink carriers can be in the same frequency range or in different frequency ranges.

[0048] There is no restriction between the number of uplink carriers in the uplink pool and the number of downlink carriers in the downlink pool. The number of uplink carriers can be greater than, less than, or equal to the number of downlink carriers.

[0049] There is no scheduling relationship and feedback relationship restriction 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 feedback information of any one or more downlink carriers.

[0050] Based on the above, when the UE reports the capability, it is necessary to flexibly indicate the uplink and downlink capability, but in the current UE capability reporting architecture, the uplink and downlink capability is coupled together for a frequency band combination, and in the current architecture, each uplink frequency band must have a corresponding downlink frequency band. When designing for future communication, the uplink frequency band does not necessarily have a corresponding downlink frequency band.

[0051] In an embodiment, FIG. 3 is a flowchart of an information reporting method provided by the embodiment of the present disclosure. The embodiment is applied to the case of decoupling the uplink and downlink capability. The embodiment can be executed by a first communication device. For example, the first communication device can be a terminal side (such as a UE). As shown in FIG. 3, the embodiment includes steps S110-S120.

In an example, the uplink capability set can include relevant uplink capability of baseband processing and relevant uplink capability of radio frequency processing in the UE; the downlink capability set can include relevant downlink capability of baseband processing and relevant downlink capability of radio frequency processing in the UE.

[0054] Step S120, reporting the uplink capability set and the downlink capability set to a second communication device.

[0055] The first communication device separately reports the uplink capability set and the downlink capability set to the second communication device, so as to realize the decoupling effect between the uplink capability set and the downlink capability set.

[0056] In an embodiment, the information reporting method applied to the first communication device further includes: reporting decoupling combination criteria between the uplink capability set and the downlink capability set to the second communication device. The decoupling combination criteria refer to the use configuration rules formulated for the uplink capability set and the downlink capability set. In actual communication process, there are some similar attributes between the uplink capability set and the downlink capability set, that is, some capability elements containing the same attributes, at this time, the uplink capability set and the downlink capability set cannot be matched arbitrarily, and the corresponding use configuration rules can be formulated for the uplink capability set and the downlink capability set. The corresponding use configuration rules can be formulated according to the decoupling degree.

[0057] In an embodiment, the method further comprises: dividing the frequency bands into corresponding uplink frequency band pools and downlink frequency band pools; and reporting the maximum capability supported by each uplink frequency band pool and downlink frequency band pool.

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 carriers aggregated by the consecutive 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 carriers aggregated by the consecutive carriers on each downlink frequency band.

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

[0065] In an embodiment, any uplink frequency band combination in each uplink frequency band pool supports a corresponding uplink frequency band combination type; any downlink frequency band combination in each downlink frequency band pool supports a corresponding downlink frequency band combination type.

For example, as shown in Figure 5, one carrier combination type corresponding to the frequency band pool supports the combination of 3 frequency bands, the first frequency band supports 1 carrier, the second frequency band supports 2 carriers, and the third frequency band supports 3 carriers. This can be represented in the form of {class A, class B, class C}. The number of class elements indicates the number of frequency bands in the supported frequency combination, and the class type indicates the number of carriers on each frequency band (for example, class A corresponds to 1 carrier, class B corresponds to 2 carriers, class C corresponds to 3 carriers, and class D corresponds to 4 carriers).

[0136] The UE reports the corresponding UE capability by reporting the frequency band combination type. For example, for the UE to report the frequency band combination type {class A, class B, class C}, it also represents the frequency band combination type of any fallback supported by the UE, such as {class A}, {class B}, {class C}, {class A, class B}, {class A, class C}, {class B, class C}, and the like.

[0137] 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, contiguous carrier aggregation information, and non-contiguous carrier aggregation information. For example, {class A, class B, class C} indicates that class A and class B are the same frequency band, and class C is a different frequency band. The UE can also indicate how many different frequency bands are included in a frequency band combination type.

[0138] If some frequency bands in a frequency band pool have stronger capabilities than in the pool, they can also be reported separately.

[0139] Furthermore, the specific capabilities on each carrier, such as bandwidth, can be indicated for different carrier combination types. There are several ways to indicate the specific capabilities on each carrier.

[0140] Way one: based on the display of the indication, i.e. for different carrier combination types, indicating the specific capability on each frequency band, such as bandwidth, number of transmission ports, number of receiving ports, number of MIMO layers, modulation and demodulation mode, etc. It should be noted that these capabilities contain uplink and downlink.

[0141] Way two: based on implicit or implicit and display combined mode, for example, indicating the maximum aggregated bandwidth, total number of transmission ports, total number of receiving ports, maximum MIMO layer, highest modulation and demodulation mode, etc. For example, there are three different granularities of this indication mode

[0142] For each frequency band type, the maximum aggregated bandwidth is the sum of the bandwidth supported by all carriers in this type, the total number of transmission and receiving ports is the sum of the number of ports on all carriers, the maximum MIMO layer is the maximum MIMO layer supported by a single carrier or the aggregated MIMO layer supported by all carriers, and the highest modulation and demodulation mode is the highest modulation and demodulation mode supported by a single carrier.

[0143] For multiple carriers (such as a certain number of consecutive carriers or aggregated carriers in a frequency band): At this time, the maximum aggregated bandwidth, total number of transmission / receiving ports, maximum MIMO layer, and highest modulation and demodulation mode under different classes (or different number of carriers) can be defined.

[0144] For all frequency band types; At this time, the capability reporting is independent of the specific frequency band type, or in other words, the capability limit at this time is applicable to all frequency band types, the maximum aggregated bandwidth is the sum of the bandwidth supported by all carriers, the total number of transmission and receiving ports is the sum of the number of ports on all carriers, the maximum MIMO layer is the maximum MIMO layer supported by a single carrier or the aggregated MIMO layer supported by all carriers, and the highest modulation and demodulation mode is the highest modulation and demodulation mode supported by a single carrier.

[0145] It should be noted that the indicated capabilities can contain uplink and downlink, for example, the bandwidth contains uplink bandwidth and downlink bandwidth, uplink MIMO layer and downlink MIMO layer, and uplink modulation and demodulation mode and uplink modulation and demodulation mode.

[0146] Wherein 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 mode of the frequency band, and the carrier combination type can indicate the combination mode of the carrier.

[0147] In the current UE capability reporting, it is mainly based on the frequency band combination to report. In this way, the UE reports the corresponding capability for different frequency band combinations, and when in actuality, the UE capability reported on many adjacent frequency bands is actually very similar, or even consistent, that is, from the UE's capability set 1 (such as radio frequency capability), it is mainly related to the frequency range it is in. For example, as shown in Table 1, the 3GPP Radio Access Technology (RAT) in FR1 (frequency Range 1, 450MHz-6000MHz, also known as sub6G) can be mainly divided into LB, MHB and UHB, that is, the 3GPP terminology of Low band, Mid band, High band, generally 3.5-4.9GHz shares a set of antennas, 1.7-2.7GHz shares a set of antennas, and Low band shares a set of antennas.

[0148] Table 1

[0149] In this way, although the capabilities supported by the UE in the same frequency range are similar or consistent, the UE still needs to report the corresponding capabilities for each frequency band or each frequency band combination, resulting in excessive UE capability signaling overhead.

[0150] In order to facilitate the understanding of the scheme provided by the present disclosure, the frequency band combination type and the indication method of the specific capability are described below in combination with specific embodiments.

[0151] Embodiment one

[0152] This embodiment mainly describes the frequency band pool and the frequency bands and carrier combination types supported thereby

[0153] In the embodiment, the frequency band pool contains three frequency bands (bands) respectively denoted as band 1, band 2, and band 3 (or three carriers, namely carrier 1, carrier 2, and carrier 3), and the carrier types corresponding to this pool are three, denoted as Class A_Class B_Class C, Class C_Class C, and Class D. Figure 6 is a schematic diagram of a frequency band pool and the frequency bands and carrier combination types supported thereby provided by the embodiment of the present disclosure, as shown in Figure 6, which means that the UE supports the following band combinations (and the fallback combinations thereof, the fallback combination means the combination left after deleting one or more carriers in the combination).

[0154] 3 band combination: Band 1 Class A_band 2 Class B_band 3 Class C, where band 1 / 2 / 3 can be exchanged arbitrarily, i.e. not affected by the band number order, i.e. Band 2 Class A_band 1 Class B_band 3 Class C can also be supported.

[0155] 2 band combination: Band 1 Class C_Band 2Class C and Band 1 Class C_Band 3Class C and Band 1 2Class C_Band 3 Class C.

[0156] 1 band combination: Band 1 Class and Band 2 Class D and Band 3 Class D.

[0157] Embodiment Two

[0158] This embodiment mainly describes the band and carrier combination type and its supported specific capability indication. The specific capability indication in this embodiment is based on the explicit indication. That is, for different band and carrier combination types, the capability supported by each carrier in the band and carrier combination type is indicated, for example, as shown in Table 2.

[0159] Table 2

[0160] The UE will report its corresponding capability for each carrier and each CC in the band combination, such as bandwidth, number of transmit ports, number of receive ports, or number of layers supporting MIMO, modulation and demodulation mode, etc.

[0161] Embodiment Three

[0162] This embodiment mainly describes the band and carrier combination type and its supported specific capability indication, including implicit or implicit and explicit combination indication.

[0163] The implicit or implicit and explicit combination indication, i.e. indicating the maximum aggregated bandwidth, total number of transmit ports, total number of receive ports, maximum number of MIMO layers, highest modulation and demodulation mode, etc. can be indicated for a carrier unit or all carrier units. For a carrier unit, i.e. the constraint cannot be exceeded on each carrier unit, and for all carrier units, it represents that the sum of the capabilities on all carrier units cannot exceed this constraint.

[0164] There are three different granularities for this indication method:

[0165] 1. For each carrier and band type;

[0166] 2. For multiple carriers (such as contiguous carriers on one band or aggregated number of carriers);

[0167] 3. For all carriers and band types.

[0168] For the first way, as shown in Table 3.

[0169] Table 3

[0170] For the second way, as shown in Table 4.

[0171] Table 4

[0172] For the third way, as shown in Table 5.

[0173] Table 5

[0174] In the above embodiments, the band combination type can also be implicitly indicated by its supported specific capability (i.e. no need to report specifically), for example, in the first way, only the band pool and its supported specific capability can be included, and the type does not need to be reported specifically.

[0175] In the following embodiments, the first communication device is taken as a UE, and the second communication device is taken as a network side, the first capability set is taken as a baseband capability, and the second capability set is taken as a radio frequency capability, and the independent reporting process of the baseband capability and the radio frequency capability is described.

[0176] The baseband capability is mainly embodied as the number of MIMO layers, the number of CCs, and the baseband bandwidth, etc., while the radio frequency capability is mainly embodied as the number of CCs, the radio frequency bandwidth, and the power, etc. In order to realize decoupling, the baseband capability and the radio frequency capability need to be reported independently, 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 of the baseband capability and the radio frequency capability.

[0177] The first part: the baseband capability includes the following three independent reporting ways:

[0178] The first way, the baseband maximum capability index or capacity index is reported, which is calculated by a formula, and the input parameters of the formula can include the number of CCs, the bandwidth (which can be the total aggregated bandwidth on all bands, the total aggregated bandwidth on each band, the bandwidth on each CC, etc.), the maximum MIMO layer number (or the sum of MIMO layer numbers), and numerology, etc.

[0179] In an example, the UE can support any capability combination lower than or equal to the index;

[0180] The formula can be defined by the protocol or reported by the UE to the network side.

[0181] When the network side is configured, the same formula can be used for calculation and configuration to ensure that the configured capability does not exceed the capability index reported by the UE.

[0182] The maximum capability index or maximum capacity index can include multiple indicators, such as computing power, storage capacity / space, process / thread number, etc.

[0183] Method two: Distributed indicators, such as reporting one or more multi-dimensional capability groups (also referred to as baseband capability groups) by the UE, wherein each multi-dimensional capability group can include {maximum number of supported CCs, maximum aggregated bandwidth, maximum MIMO layer (or sum of MIMO layers), numerology or numerology combination}, and the network side selects one group for configuration, as shown in Table 6.

[0184] Table 6

[0185] Method three: Report the maximum capability of each CC under different CC numbers.

[0186] Second part: Separate reporting of radio frequency capability: Radio frequency capability is related to frequency band, and the reporting method can refer to the above reporting method based on frequency band pool (i.e. embodiments one to three). In the above reporting process of the frequency band pool, if only the radio frequency related capability is reported in the "indication of specific capabilities on each carrier for different carrier / band combination types", it can be regarded as the reporting of the radio frequency capability, and if the capability is integrated with the baseband and radio frequency, it can be regarded as the unified reporting of the radio frequency capability and the baseband capability.

[0187] Third part: decoupling combination criteria between baseband capability and radio frequency capability. As can be seen from the above, there are some similar attributes between the radio frequency capability and the baseband capability, for example, on the carrier aggregation, the influence on the baseband is reflected in the number of CCs, and the influence on the radio frequency may be mainly reflected in the number of CCs or frequency blocks. On the MIMO, the influence on the baseband is reflected in the maximum MIMO layer number, and the influence on the radio frequency is mainly reflected in the total number of MIMO layers or the total number of antenna ports, so there is a certain correlation between the baseband and the radio frequency capability, thereby restricting that the baseband capability and the radio frequency capability cannot be matched arbitrarily, for example, a set of two-port radio frequency capability cannot match a 4 MIMO layer baseband capability, so it is necessary to formulate corresponding use pairing rules for the independently reported baseband capability and the radio frequency capability. In addition, for different frequency ranges such as low / middle / high frequencies, the aggregated bandwidth, the used numerology, the MIMO layer number and the like may be different, so according to whether the specific frequency band is divided, there are the following two reporting modes:

[0188] Reporting mode one: partial decoupling, that is, the UE reports the corresponding baseband capability for different frequency band pools or frequency ranges, but the baseband capability in the same frequency band pool or frequency range is independent of the corresponding frequency band. Further, the use pairing rules of the radio frequency capability and the baseband capability can be formulated. FIG. 7 is a configuration schematic diagram of constraint rules of the frequency band capability and the baseband capability in the partial decoupling scene provided by the embodiment of the present disclosure. As shown in FIG. 7, in the same frequency band pool, the baseband capability and the radio frequency capability are one-to-one corresponding.

[0189] The rules can be embodied in two ways:

[0190] Mode one: protocol constraint, for example, constraint from the number of CCs, bandwidth, MIMO layer / transmit / receive antenna port number, modulation order, numerology and the like, for example

[0191] For the number of CCs, that is, from the carrier / frequency band combination type of the radio frequency (or the number of CCs in the radio frequency capability) to the baseband capability to be matched, for example:

[0192] Class A_Class B_Class C is (6CC), so the baseband capability matched therewith should at least contain 6 carriers

[0193] For the bandwidth constraint, the final bandwidth is determined according to the reporting of the baseband capability and the radio frequency capability. For example, the baseband capability introduces a corresponding factor to convert the radio frequency capability according to different numerologies.

[0194] For MIMO layer constraint, for example, corresponding antenna port is 2Rx, then corresponding baseband capability can only be 2 layer MIMO.

[0195] For modulation demodulation mode / Numerology constraint, for example, when matching the corresponding baseband capability for radio frequency capability, the corresponding modulation demodulation mode / Numerology should be supported in the baseband capability.

[0196] Method two: UE implicit indication, that is, UE reports corresponding baseband capability and radio frequency capability adaptation constraint, for example, UE can indicate different categories of supported capabilities, and the network needs to comply with the constraints of these categories when configuring the UE, and these categories can be from the number of CCs, bandwidth, MIMO layer / transmit / receive antenna port number, modulation demodulation order and UE power class.

[0197] In these categories, both the radio frequency capability and the baseband capability are included.

[0198] In an example, FIG. 8 is a configuration diagram of band capability and baseband capability category information in a partially decoupled scenario according to an embodiment of the present disclosure. In this example, the UE can report its supported category information, that is, the category information in FIG. 8, which can be defined in whole UE granularity, or can be defined based on each band pool, and the UE can report its supported category for each band pool. The category can be pre-defined by the protocol, and the UE only needs to report the category number / identifier, or directly report the specific content of the category.

[0199] Method three: UE explicit indication, that is, directly associate the baseband capability with the radio frequency capability, for example, number the baseband capability, and then the radio frequency capability is associated by indicating the number of the baseband capability, as shown in Table 7.

[0200] Table 7

[0201] Wherein, x, y, z represent different baseband capabilities.

[0202] Note: In the above scheme, the category information supported in different carriers / frequency band groups / pools can be the same;

[0203] In the above figure, the elements of baseband and radio frequency capability in different carriers / frequency band groups / pools can be partially the same, so the baseband and radio frequency capability pool can also be defined, and then referenced by the index scheme in each carrier / frequency band group / pool.

[0204] The baseband and radio frequency capability elements in the above diagram can only contain uplink or only contain downlink, or contain both uplink and downlink.

[0205] The second reporting mode is complete decoupling, that is, the UE reports baseband capability independent of the frequency band, but the maximum capability of the baseband can be compatible with the maximum capability supported by the radio frequency, such as the number of CCs, MIMO layers, bandwidth, and the like. Further, rules can be formulated for the use of radio frequency capability and baseband capability pairing, which can be embodied in three ways similar to the partial decoupling described above.

[0206] FIG. 9 is a configuration diagram of a constraint rule between frequency band capability and baseband capability in a complete decoupling scenario according to an embodiment of the present disclosure. As can be seen in the above description, the UE reports the radio frequency capability group and the baseband capability group to the network side at the same time, and for mode two, the UE also reports the supported classification constraint.

[0207] In an example, the solution is optimized for carrier concatenation:

[0208] FIG. 10 is a diagram of a carrier concatenation mode for multi-spectrum native design according to an embodiment of the present disclosure. In the carrier concatenation diagram shown in FIG. 10, multiple radio frequency carriers are first aggregated into a large radio frequency carrier pool. The 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 capability and the carrier capability, for example, which radio frequency carriers can be aggregated into a radio frequency carrier pool, and the baseband carrier capability that can be mapped by each radio frequency carrier pool. Since in the current UE capability architecture, the radio frequency capability and the baseband capability are coupled together, this architecture of mapping multiple radio frequency carriers to a baseband carrier cannot be supported.

[0209] FIG. 11 is a configuration diagram of a constraint rule between baseband capability and radio frequency capability according to an embodiment of the present disclosure. As shown in FIG. 11, in this architecture, similar techniques are adopted, that is, multiple radio frequency capabilities are mapped to a baseband capability according to certain constraint rules. The constraint rules are similar to the three modes described above.

[0210] In this architecture, the UE will report a set of radio frequency capabilities, a set of baseband capabilities, and a mapping relationship between the radio frequency capability and the baseband capability, which can be in the three modes described above.

[0211] The reporting can be based on a frequency band pool or the entire UE.

[0212] In the following embodiments, the first communication device is taken as an example of a UE, and the second communication device is taken as an example of a network side to describe the decoupling reporting process of uplink and downlink capabilities. The uplink capability set can also be referred to as uplink capability, and the downlink capability set can also be referred to as downlink capability.

[0213] In order to realize decoupling, the uplink capability and the downlink capability need to be reported independently, and then corresponding rules are formulated according to the degree of decoupling. In the solution of uplink and downlink decoupling reporting, there are three parts: uplink capability independent reporting; downlink capability independent reporting; combination criteria after uplink and downlink decoupling (i.e. decoupling combination criteria).

[0214] Here, according to whether the radio frequency and baseband capability is decoupled as above, it can be further divided into two categories: radio frequency capability and baseband capability decoupling; radio frequency capability and baseband capability do not decouple.

[0215] FIG. 12 is a schematic diagram of uplink and downlink capability reporting in a baseband capability and radio frequency capability decoupling scenario according to an embodiment of the present disclosure, as shown in FIG. 12:

[0216] 1) In FIG. 12 as above, the downlink band pool (DL band pool) can have only one, and the uplink band pool (UL band pool) can also have only one, and the two pools can also be the same.

[0217] 2) In addition, different band pools (band pools) can also have corresponding different uplink and downlink radio frequency capabilities. This logic is similar to the previous description, which will not be repeated here.

[0218] FIG. 13 is a schematic diagram of uplink and downlink decoupling reporting of baseband capability according to an embodiment of the present disclosure. As shown in FIG. 13, for the uplink and downlink decoupling of baseband capability: in the baseband implementation, the uplink capability and the downlink capability are generally implemented independently, and there can be no certain constraints between the uplink and downlink capabilities. In order to realize the sharing of storage, computing power and other resources of uplink and downlink, the computing power value (i.e. uplink computing power constraint information or downlink computing power constraint information) or the total storage requirement of uplink and downlink may be constrained within a certain limit.

[0219] This constraint can be specified by a protocol or indicated by a UE. The UE indication can consider the following three constraint methods:

[0220] Total computing power constraint information, i.e. total computing power of uplink and downlink, similar to the foregoing, reporting baseband maximum capability index or 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 total loan of aggregation, the total bandwidth of aggregation on each band, the bandwidth on each CC, etc.), the number of maximum MIMO layers (or the sum of MIMO layers), numerology, etc.

[0221] Any combination of capabilities lower than or equal to the index can be supported by the UE; the formula can be defined by the protocol or reported by the UE to the network side; when the network side configures, the same formula can be used for calculation and configuration to ensure that the configured capability does not exceed the reported capability index of the UE; the maximum capability index or maximum capacity index can include multiple output indicators such as computing power, storage capacity / space, and process / thread number.

[0222] The UE reports its category constraints, for example, the UE reports the supported category, which contains both uplink and downlink information.

[0223] Display indication, that is, display which uplink and downlink capabilities can be matched, as shown in Table 8.

[0224] Table 8

[0225] For uplink and downlink decoupling of radio frequency capabilities: since the radio frequency chip is designed, the uplink and downlink cannot be completely independent like the baseband chip, and there is a partial coupling, which has the following several ways

[0226] FIG. 14 is a configuration diagram of radio frequency capabilities of the same frequency band pool according to an embodiment of the present disclosure. As shown in FIG. 14, similar to the foregoing, frequency bands or carriers with similar properties can be placed in a frequency band carrier group, which means that the uplink and downlink can be matched within the frequency band carrier group.

[0227] FIG. 15 is a configuration diagram of radio frequency capabilities of different frequency band pools according to an embodiment of the present disclosure. As shown in FIG. 15, for some bands, if they only support downlink or uplink carriers, the frequency band carrier group supporting uplink may not be consistent with the frequency band carrier group supporting downlink, and one or more uplink carrier groups, one or more downlink carrier groups, and the corresponding coupling relationship can be defined.

[0228] In the above description, the constraints between the uplink and downlink frequency band carrier pools can have the following several ways:

[0229] (1) conform to the protocol definition, that is, only the uplink and downlink frequency band carrier pools defined in the protocol can be combined;

[0230] (2) the uplink and downlink carrier pools at least contain the same frequency band or carrier / frequency range (TDD);

[0231] (3) display indication, for example, indicating which downlink frequency band carrier pool can be paired with which uplink frequency band carrier pool;

[0232] In the description as described above, the constraints between the uplink and downlink radio frequency capabilities can be as follows:

[0233] (1) The UE indicates the supported category, which contains the supported uplink and downlink carrier / band combination type, uplink (number of CCs, MIMO layer or number of transmit antenna ports, number of spectrum blocks, uplink bandwidth, modulation and demodulation mode) capability, downlink (number of CCs, MIMO layer or number of transmit antenna ports, number of spectrum blocks, uplink bandwidth, modulation and demodulation mode) capability, etc.

[0234] (2) Total computing power constraint. Since part of the radio frequency capability is determined by the radio frequency chip capability, the radio frequency chip capability can be designed similar to the baseband capability, and the total computing power of the uplink and downlink is constrained.

[0235] (3) Display indication, for example, indicating which downlink radio frequency capability can be paired with which uplink radio frequency capability.

[0236] FIG. 16 is a schematic diagram of uplink and downlink capability reporting in a scenario where the baseband capability and the radio frequency capability are not decoupled, according to an embodiment of the present disclosure. In the scenario where the baseband capability and the radio frequency capability are not decoupled, the uplink and downlink capability reporting process is as shown in FIG. 16.

[0237] In this architecture, the constraints between the uplink and downlink frequency band carrier pools are the same as above, and the reporting manner of the constraints between the uplink and downlink frequency band carrier pools is similar to the previous one, and the difference is that the baseband capability and the radio frequency capability are coupled together at this time, that is, corresponding to the three ways as follows:

[0238] (1) The UE indicates the supported category, which contains the supported uplink and downlink carrier / band combination type, uplink (number of CCs, MIMO layer or number of transmit antenna ports, number of spectrum blocks, uplink bandwidth, modulation and demodulation mode) radio frequency baseband capability, downlink (number of CCs, MIMO layer or number of transmit antenna ports, number of spectrum blocks, uplink bandwidth, modulation and demodulation mode) radio frequency baseband capability, etc.

[0239] (2) Total computing power constraint, including baseband computing power, radio frequency computing power, or the sum of the two.

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

[0241] In an embodiment, FIG. 17 is a structural block diagram of an information reporting apparatus provided by an embodiment of the present disclosure. The present embodiment is applied to a first communication device. As shown in FIG. 17, the information reporting apparatus in the present embodiment includes a decoupler 310 and a transmitter 320.
