Description

Information reporting method, communication device and storage medium TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, for example, to an information reporting method, a communication device and a storage medium. BACKGROUND

[0002] 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 reported by the UE will be more, and if the above UE capability architecture is still used, the overhead of the UE capability signaling will be impacted.

[0033] 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 technology, since the UE needs to report the corresponding frequency band combination capability to support carrier aggregation and multi-connection, thereby greatly increasing the signaling overhead.

[0034] In 5G, in order to reduce such overhead, the concepts of FeatureSetCombination and FeatureSet are defined, as shown in FIG. 1, which is a 5G UE capability architecture based on FeatureSetCombination provided in the related 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 above 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 combinations supported by the UE, the size of the UE capability signaling is also increasing.

[0035] Meanwhile, compared with 5G, in order to adapt to more scenarios for more flexible deployment, 6G will support more networking types. For example, in 5G, the number of uplink carriers cannot be greater than the number of downlink carriers for a frequency band combination, but in 6G, this limitation will be broken to adapt to more video upload services. This means that the UE will report more frequency band combinations, and if the above UE capability architecture is still used, the overhead of UE capability signaling will be impacted.

[0036] FIG. 2 is a schematic diagram of decoupling of uplink and downlink provided by the related art. As shown in FIG. 2, in order to meet the requirement of more flexible uplink and downlink carrier pairing, decoupling of uplink and downlink is needed, for example, the uplink pool and the downlink pool are decoupled. The decoupling mainly includes the following aspects:

[0037] There is no frequency band 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 band or in different frequency bands.

[0038] 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.

[0039] There is no restriction between the scheduling relationship and the feedback relationship between the uplink carriers and the downlink carriers. 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.

[0040] Based on the above, when the UE reports the capability, it needs to be able to flexibly indicate the uplink and downlink capability, but in the UE capability reporting architecture, the uplink and downlink capability is coupled together for a frequency band combination, and in the above UE capability architecture, each uplink frequency band must have a corresponding downlink frequency band. However, in the design of future communication, the uplink frequency band does not necessarily have a corresponding downlink frequency band.

[0041] In an embodiment, FIG. 3 is a flowchart of an information reporting method provided by the embodiment of the present application. The embodiment is applied to the decoupling of 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 S110-S130.

[0107] FIG. 5 is a UE capability architecture diagram based on a frequency band pool according to an embodiment of the present application. As shown in FIG. 5, different frequency bands are divided into multiple frequency band pools according to their similar capabilities. For example, the frequency band pool 1 comprises frequency bands 1 to 4, and the frequency band pool 2 comprises frequency bands 5 to 7. For each frequency band pool, one or more frequency band combination types supported by the frequency band pool are defined.

[0108] The band combination type indicates the combination type of the bands in the band combination. Any band combination in the band pool supports the carrier combination type corresponding to the band pool.

[0109] The band combination type indicates the number of bands in the band combination, and the number of carriers on each band. For example, as shown in FIG. 5, one carrier combination type corresponding to the band pool supports the combination of 3 bands, the first band supports 1 carrier, the second band supports 2 carriers, and the third band supports 3 carriers. The combination can be represented in the form of {class A, class B, class C}, the number of class elements can be used to indicate the number of bands in the supported frequency combination, and the class type can be used to indicate (for example, class A corresponds to one carrier, class B corresponds to 2 carriers, class C corresponds to 3 carriers, and class D corresponds to 4 carriers).

[0110] The UE reports the band combination type to report the corresponding UE capability. For example, for the UE to report the band combination type {class A, class B, class C}, it also represents the band combination type of any one fallback that the UE can support, such as {class A} {class B} {class C} {class A, class B} {class A, class C} {class B, class C}, etc.

[0111] The UE further indicates at least one of the following information in the reported band combination type: same frequency band information, different frequency band information, continuous carrier aggregation information, and discontinuous 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 the different frequency band. The UE can also indicate how many different bands are included in a band combination type.

[0112] If some bands in the band pool have stronger capabilities than in the pool, they can also be reported separately.

[0113] Further, 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 the carrier:

[0114] Method one: display-based indication, that is, for different carrier combination types, the specific capabilities on each band are indicated, such as bandwidth, the number of transmission ports, the number of receiving ports, the number of layers supporting MIMO, and the modulation and demodulation mode. These capabilities include uplink and downlink.

[0115] Way two: implicit or implicit and explicit combination, for example, indicating the maximum aggregated bandwidth, the total number of sending ports, the total number of receiving ports, the maximum MIMO layer number, the highest modulation and demodulation mode, etc. For example, there are three different granularities in this indication mode.

[0116] 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 sending and receiving ports is the sum of the port numbers on all carriers, the maximum MIMO layer number is the maximum MIMO layer number supported by a single carrier or the aggregated MIMO layer number supported by all carriers, and the highest modulation and demodulation mode is the highest modulation and demodulation mode supported by a single carrier.

[0117] For multiple carriers (such as consecutive carriers in a frequency band or the number of aggregated carriers): the maximum aggregated bandwidth, the total number of sending and receiving ports, the maximum MIMO layer number, and the highest modulation and demodulation mode under different classes (or different carrier numbers) can be defined.

[0118] For all frequency band types, the capability reporting is independent of the specific frequency band type, or the capability limit 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 sending and receiving ports is the sum of the port numbers on all carriers, the maximum MIMO layer number is the maximum MIMO layer number supported by a single carrier or the aggregated MIMO layer number supported by all carriers, and the highest modulation and demodulation mode is the highest modulation and demodulation mode supported by a single carrier.

[0119] The indicated capabilities can include uplink and downlink, for example, the bandwidth includes uplink bandwidth and downlink bandwidth, the uplink MIMO layer number and the downlink MIMO layer number, and the uplink modulation and demodulation mode and the uplink modulation and demodulation mode.

[0120] 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 bands in the frequency band, and the carrier combination type can indicate the combination mode of the carriers.

[0121] In the UE capability reporting, the main is based on the band combination to report. In this way, the UE reports the corresponding capability for different band combinations, and when in actual, the UE capability reported on many adjacent frequency bands is actually very similar, 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, 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, Low band, Mid band, High band in 3GPP terminology. 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.

[0122] Table 1

[0123] 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.

[0124] In order to facilitate the understanding of the scheme provided in the present application, the frequency band combination type and the indication method of the specific capability are described below in combination with specific embodiments.

[0125] Embodiment one

[0126] This embodiment mainly describes the frequency band pool and the frequency bands and carrier combination types supported thereby

[0127] 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 the 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 according to an embodiment of the present application, as shown in Figure 6, which means that the UE supports the following band combinations (and fallback combinations, which are combinations left over after deleting one or more carriers in the combination).

[0128] 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, etc. can also be supported.

[0129] 2 band combination: 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.

[0130] 1 band combination: Band 1 Class D and Band 2 Class D and Band 3 Class D.

[0131] Embodiment Two

[0132] 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.

[0133] Table 2

[0134] The UE will report its corresponding capability for each carrier and band combination on each CC, such as bandwidth, number of transmit ports, number of receive ports, or number of layers supporting MIMO, modulation and demodulation mode, etc.

[0135] Embodiment Three

[0136] This embodiment mainly describes the band and carrier combination type and its supported specific capability indication, including implicit or implicit and explicit combination indication.

[0137] 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.

[0138] There are three different granularities for this indication method:

[0139] 1. For each carrier and band type.

[0140] 2. For multiple carriers (such as contiguous carriers on one band or aggregated number of carriers).

[0141] 3. For all carriers and band types.

[0142] For the first way, as shown in Table 3.

[0143] Table 3

[0144] For the second way, as shown in Table 4.

[0145] Table 4

[0146] For the third way, as shown in Table 5.

[0147] Table 5

[0148] In the above embodiments, the band combination type can also be implicitly indicated by its supported specific capabilities (i.e. no need to report specifically), for example, in the first way, only the band pool and its supported specific capabilities can be included, and the type does not need to be reported specifically.

[0149] 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.

[0150] 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 baseband capability; independent reporting of radio frequency capability; decoupling combination criteria of baseband capability and radio frequency capability.

[0151] The first part: the baseband capability includes the following three independent reporting ways:

[0152] The first way, the baseband maximum capability index or capacity index is reported, which is calculated through 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.

[0153] In an example, the UE can support any capability combination lower than or equal to the index; the 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 capability does not exceed the capability index reported by the UE; the maximum capability index or maximum capacity index can include multiple indicators, such as computing power, storage capacity / space, process / thread number, etc.

[0154] 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.

[0155] Table 6

[0156] Method three: Report the maximum capability of each CC under different CC numbers.

[0157] 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 “indicating the specific capability on each carrier for different frequency band and carrier class 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.

[0158] 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 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 frequency blocks. On the MIMO, the impact on the baseband is reflected in the maximum MIMO layer number, and the impact 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 4MIMO 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 numerology used, the MIMO layer number, etc. may also be different, so according to whether the specific frequency band is divided, there are the following two reporting modes:

[0159] 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, as above, rules can be formulated for the use pairing of the radio frequency capability and the baseband capability. FIG. 7 is a configuration schematic diagram of constraint rules of the frequency band capability and the baseband capability in a partial decoupling scenario according to an embodiment of the present application. As shown in FIG. 7, in the same frequency band pool, the baseband capability and the radio frequency capability are one-to-one corresponding.

[0160] The rules can be embodied in two ways:

[0161] Mode one: protocol constraint, for example, constraint from the number of CCs, bandwidth, MIMO layer / transmit-receive antenna port number, modulation order, numerology, etc. For example, the constraint rule for the maximum number of supported CCs, that is, from the 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: Class A_Class B_Class C is (6CC), then the baseband capability matched therewith should at least contain 6 carriers; the bandwidth constraint rule, according to the reporting of the baseband capability and the radio frequency capability to jointly determine the final bandwidth. For example, the baseband capability introduces a corresponding factor to convert the radio frequency capability according to different numerologies.

[0162] The constraint rule for the maximum MIMO layer, for example, the corresponding antenna port is 2Rx, then the corresponding baseband capability can only be 2 layers of MIMO.

[0163] For the constraint rules of modulation and numerology, for example, when matching the baseband capability to the radio frequency capability, the corresponding modulation and numerology should be supported in the baseband capability.

[0164] Method two: UE implicit indication, that is, the UE reports the adaptation constraint of the corresponding baseband capability and radio frequency capability, for example, the UE can indicate different classification information of the supported capability, and the network needs to comply with the constraint rules of the classification information when configuring the UE. The classification information can include the number of CCs, bandwidth, MIMO layer / transmit / receive antenna port number, modulation order, and UE power class.

[0165] In the classification information, both the radio frequency capability and the baseband capability are included.

[0166] In an example, FIG. 8 is a configuration diagram of the classification information of the frequency band capability and the baseband capability in a partially decoupled scenario according to an embodiment of the present application. In this example, the UE can report the classification information supported by the UE, that is, the classification information (Category information) in FIG. 8. The information can be defined in the granularity of the entire UE, or can be defined based on each band pool. The UE can report the category class supported by the UE 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.

[0167] Method three: UE explicit indication, that is, directly associating the baseband capability with the radio frequency capability, for example, numbering the baseband capability, and then the radio frequency capability is associated with each other by indicating the number of the baseband capability, as shown in Table 7.

[0168] Table 7

[0169] In the table, x, y, and z represent different baseband capabilities.

[0170] Note: In the above scheme, the classification information supported in different carriers / frequency band groups / pools can be the same. In the above diagram, the elements of the baseband and radio frequency capability can be partially the same in different carriers / frequency band groups / pools, so the baseband and radio frequency capability pools can be defined, and then referenced by the Index scheme in each carrier / frequency band group / pool.

[0171] In the above diagram, the elements of the baseband and radio frequency capability can only include uplink or only include downlink, or simultaneously include uplink and downlink.

[0172] Reporting mode two: complete decoupling: that is, the UE reports the baseband capability independently 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, etc. 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 above partial decoupling.

[0173] Figure 9 is a configuration diagram of the constraint rules of the frequency band capability and the baseband capability in the complete decoupling scenario according to an embodiment of the present application. 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, and for mode two, the UE also reports the supported classification constraints.

[0174] In an example, the solution is optimized for carrier concatenation: Figure 10 is a schematic diagram of a carrier concatenation mode for multi-spectrum native design according to an embodiment of the present application. In the carrier concatenation diagram as shown in 10, multiple radio frequency carriers are first aggregated into a large radio frequency carrier pool. 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 capability and the carrier capability, for example: which radio frequency carriers can be aggregated into a radio frequency carrier pool, and which baseband carrier capabilities can be mapped by each radio frequency carrier pool. Since in the UE capability architecture, the radio frequency capability and the baseband capability are coupled together, it is not possible to support this architecture in which multiple radio frequency carriers are mapped to a baseband carrier.

[0175] Figure 11 is a configuration diagram of the constraint rules between the baseband capability and the radio frequency capability according to an embodiment of the present application. As shown in Figure 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 above three modes.

[0176] In this architecture, the UE will report a set of radio frequency capabilities, a set of baseband capabilities, and the mapping relationship between the radio frequency capability and the baseband capability, which can be in the three ways described above.

[0177] The reporting can be based on a frequency band pool or the entire UE.

[0178] In the following embodiments, the first communication device is taken as an example of the UE, and the second communication device is taken as an example of the network side to explain the decoupling reporting process of the uplink and downlink capabilities. Among them, the uplink capability set can also be referred to as the uplink capability; the downlink capability set can also be referred to as the downlink capability.

[0179] To achieve decoupling, the uplink and downlink capabilities need to be reported separately, and then the 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).

[0180] Here, according to whether the radio frequency and baseband capabilities are decoupled as above, it can be further divided into two categories: radio frequency capability and baseband capability decoupling; radio frequency capability and baseband capability are not decoupled.

[0181] FIG. 12 is an uplink and downlink capability reporting diagram in a baseband capability and radio frequency capability decoupling scenario according to an embodiment of the present application, as shown in FIG. 12:

[0182] 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.

[0183] 2) In addition, different band pools (band pool) can also have corresponding different uplink and downlink radio frequency capabilities, which are similar to the previous description, and will not be repeated here.

[0184] FIG. 13 is an uplink and downlink decoupling reporting implementation diagram of baseband capability according to an embodiment of the present application. 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.

[0185] This constraint can be specified by a protocol or indicated by a UE. The UE indication can consider the following three constraint methods: total computing power constraint information, i.e. total uplink and downlink computing power, similar to the above, reporting the maximum baseband capability index or maximum capacity index, which is calculated by a formula. The input parameters of the formula can include the number of CCs, the bandwidth (which can be the total aggregated loan, 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), numerology, etc.

[0186] The UE can support any combination of capabilities lower than or equal to the index; the formula can be defined by the protocol or reported by the UE to the network side; when the network side is configured, the same formula can be calculated and configured 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, process / thread number, etc.

[0187] The UE reports its category constraints, such as the category supported by the UE, which contains both uplink and downlink information.

[0188] Display indication, i.e., display which uplink and downlink capabilities can be matched, as shown in Table 8.

[0189] Table 8

[0190] 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 partial coupling, which has the following several ways:

[0191] FIG. 14 is a configuration diagram of radio frequency capabilities of the same frequency band pool according to an embodiment of the present application. As shown in FIG. 14, similar to the previous, 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.

[0192] FIG. 15 is a configuration diagram of radio frequency capabilities of different frequency band pools according to an embodiment of the present application. 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.

[0193] In the above description, the constraints between the uplink and downlink frequency band carrier pools can have the following several ways:

[0194] (1) comply with the protocol definition, i.e., only the uplink and downlink frequency band carrier pools defined in the protocol can be combined.

[0195] (2) The uplink and downlink carrier pools contain at least the same frequency band or carrier / frequency range (TDD).

[0196] (3) Display indication, such as indicating which downlink frequency band carrier pool can be paired with which uplink frequency band carrier pool.

[0197] In the above description, the constraints between the uplink and downlink radio frequency capabilities can have the following several ways:

[0198] (1) UE indicates its supported category, in which the category information contains supported uplink and downlink carrier / band combination type, uplink (CC number, MIMO layer or number of transmit antenna ports, number of spectrum blocks, uplink bandwidth, modulation and demodulation mode) capability, downlink (CC number, MIMO layer or number of transmit antenna ports, number of spectrum blocks, uplink bandwidth, modulation and demodulation mode) capability, etc.

[0199] (2) Total computing power constraint, since in the radio frequency capability, a part is determined by the radio frequency chip capability, and 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.

[0200] (3) Display indication, for example, indicating which downlink radio frequency capability can be paired with which uplink radio frequency capability.

[0201] FIG. 16 is a schematic diagram of uplink and downlink capability reporting in a scenario where baseband capability and radio frequency capability are not decoupled, according to an embodiment of the present application. 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.

[0202] In this architecture, the constraint between the uplink and downlink frequency band carrier pools is the same as before, and the reporting manner of the constraint between the uplink and downlink frequency band carrier pools is also similar to before, and the difference is that the baseband capability and the radio frequency capability are coupled together at this time, that is, corresponding to three ways as follows:

[0203] (1) UE indicates its supported category, in which the category information contains supported uplink and downlink carrier / band combination type, uplink (CC number, MIMO layer or number of transmit antenna ports, number of spectrum blocks, uplink bandwidth, modulation and demodulation mode) radio frequency baseband capability, downlink (CC number, MIMO layer or number of transmit antenna ports, number of spectrum blocks, uplink bandwidth, modulation and demodulation mode) radio frequency baseband capability, etc.

[0204] (2) Total computing power constraint, containing baseband computing power, radio frequency computing power, or the sum of the two.

[0205] (3) Display indication, for example, indicating which downlink radio frequency capability can be paired with which uplink radio frequency capability.
