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.

[0036] 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, since the UE needs to report the corresponding frequency band combination capability to support carrier aggregation and multi-connection, which greatly increases the signaling overhead.

[0037] 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 related art. Many 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 band combination supported and the corresponding FeatureSetCombinationID, and with the increase of the band combinations supported by the UE, the size of the UE capability signaling is also increasing.

[0038] Meanwhile, 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 cannot 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 to a certain extent.

[0039] In the hardware and chip design of the UE, there are two modules of baseband processing and radio frequency processing. The baseband processing mainly includes: CRC / channel coding, rate matching, HARQ, scrambling, modulation, layer mapping, multi-antenna precoding, resource mapping, physical antenna mapping, etc. The radio frequency processing converts digital signals into analog signals for transmission or vice versa.

[0040] For baseband processing, the baseband capability is embodied as the number of component carriers (CCs), bandwidth, maximum number of MIMO layers, numerology (parameter set, including subcarrier spacing, symbol length, and cyclic prefix length, etc.), and other specific physical channel capabilities, etc. For radio frequency processing, the radio frequency capability is embodied as the number of CCs, antenna port number, bandwidth, transmit power, radio frequency filtering bandwidth, etc. Among them, for the CA scenario, in addition to the number of CCs, the number of spectrum blocks also has a certain impact on the radio frequency chip design, in which a continuous carrier is recorded as a spectrum block. Under normal circumstances, a continuous carrier block can be received by the same Rx chain (radio frequency link), and for a powerful receiving antenna, those same frequency discontinuous carrier blocks can also be received by one RF chain.

[0041] In the related discussion of 6G, in order to realize multi-spectrum native, it is necessary to support decoupling of baseband and radio frequency and pooling of radio frequency carriers: pooling multiple scattered radio frequency carriers into a continuous baseband carrier. Baseband processing based on a continuous baseband carrier can achieve the following effects: reducing the complexity of network management, reducing the workload of network management network planning and optimization, improving the utilization efficiency of scattered spectrum (such as reclaimed FDD spectrum or TDD spectrum), expanding the transmission bandwidth of channel signals such as PDSCH / PUSCH, improving traffic, and reducing overhead (configuration, scheduling, feedback). Among them, the baseband carrier refers to a set of subcarriers with one or more subcarrier intervals; the radio frequency carrier refers to an absolute frequency domain range (for example, 2450MHz to 2550Mhz), or an absolute frequency domain range within a certain frequency band, which can be represented by an absolute frequency point ARFCN and a bandwidth. In order to support this technology, the baseband capability and radio frequency capability of the UE also need to be decoupled accordingly, so as to realize flexible pairing. However, in the above UE capability architecture, the UE capability is reported based on each band combination, and the corresponding baseband capability and radio frequency capability are reported for each band combination, that is, a high-coupling reporting mode.

[0042] FIG. 2 is a schematic diagram of a UE capability reporting structure provided by the related art. As shown in FIG. 2, from the UE capability architecture, the reporting of a certain baseband capability (BC) of the UE under the same radio access technology (RAT) is mainly based on the 5-part coupling in FIG. 2.

[0043] In the case of merging BCs with the same {DL / UL, RF capability, Baseband Capability}, it can be further considered whether RF capability and Baseband Capability can continue to be decoupled. In the capability architecture, the two types of capabilities are coupled together through featureSetCombinaiton, so that N sets of RF capability capability sets and M sets of Basedband Capability capability sets can be coupled to N*M sets of featureSetCombinaiton (of course, the UE can only report the supported part of the combination). FIG. 3 is a schematic diagram of reporting of RF capability and baseband capability provided by the related art. As shown in FIG. 3, in actual terminal chip design, some parts of the baseband capability and the RF capability are completely independently designed. For example, after the signal is processed by the RF, it becomes a single CC granularity signal, and the baseband processing module processes the signal according to the CC granularity, that is, the signal transmitted to the baseband processing module becomes a CC granularity signal. In other words, from the baseband, it is not necessary for the baseband processing module to know whether these CCs are intra-band contiguous (two carriers belong to the same frequency band and are continuous in the frequency domain), intra-band non-contiguous (two carriers belong to the same frequency band but are not continuous in the frequency domain), or inter-band (two carriers belong to different frequency bands), and the implementation of the baseband also does not have a specific impact.

[0044] FIG. 4 is another schematic diagram of reporting of RF capability and baseband capability provided by the related art. As shown in FIG. 4, if the baseband capability and the RF capability are mixed together, the total number of FeatureSetCombination will be increased, and the number of featuresets at the band level will also be increased. If the baseband capability and the RF capability are decoupled and reported, and certain restrictions are imposed on the related parts, the signaling overhead of UE capability can be reduced. For example, it can be necessary to report only N sets of RF capability combinations, M sets of baseband capability combinations (depending on the baseband capability reporting manner described below), and related restrictions (optional), as shown in the following embodiment of separate reporting of baseband capability and RF capability.

[0045] The band combination type in the present application can also be referred to as a carrier combination type, and the band pool can also be referred to as a carrier pool.

[0046] In an embodiment, FIG. 5 is a flowchart of a method for reporting information according to an embodiment of the present application. The embodiment is applied to the case of separately reporting the radio frequency capability and the baseband capability of the UE. The embodiment can be performed by a first communication device. For example, the first communication device can be a terminal side (e.g., a UE). As shown in FIG. 5, the embodiment includes S110-S120.

[0047] S110, decoupling the UE capability into a first capability set and a second capability set.

[0048] In each capability set, there are capability elements with strong correlation. That is, the capability elements in the first capability set have strong correlation, and the capability elements in the second capability set have strong correlation. In an example, there can be some capability elements with the same attribute between the first capability set and the second capability set.

[0049] S120, reporting the first capability set and the second capability set to a second communication device.

[0050] The first communication device can separately report the first capability set and the second capability set to the second communication device, so as to achieve the decoupling effect between the first capability set and the second capability set.

[0051] In an embodiment, the method for reporting information by the first communication device further includes reporting a decoupling combination criterion between the first capability set and the second capability set to the second communication device. The decoupling combination criterion refers to a usage pairing rule made for the first capability set and the second capability set. In actual communication, there are some similar attributes between the first capability set and the second capability set, that is, there are some capability elements with the same attribute. At this time, the first capability set and the second capability set cannot be matched arbitrarily, and a corresponding usage configuration rule can be made for the first capability set and the second capability set.

[0052] In an embodiment, the first capability set includes the related capability of the baseband processing in the UE, and the second capability set includes the related capability of the radio frequency processing in the UE. The first communication device can divide the capability sets according to different modules included in the UE. For example, the UE includes radio frequency processing and baseband processing. The capability related to the baseband processing can be divided into a capability set as the first capability set, and the capability related to the radio frequency processing can be divided into a capability set as the second capability set. In an example, the first capability set and the second capability set can include some capability elements with the same attribute, that is, the capability elements are determined by the radio frequency processing module and the baseband processing module. In an example, the related capability of the baseband processing can also be referred to as the baseband capability, and the related capability of the radio frequency processing can also be referred to as the radio frequency capability.

[0053] In an embodiment, the reporting manner of the first capability set comprises at least one of the following: reporting a maximum capability index or a maximum capacity index; reporting at least one multi-dimensional capability group; reporting a maximum capability supported by each CC.

[0054] In an example, the first capability set can comprise three independent reporting manners:

[0055] Firstly, the first communication device reports a maximum capability index or a maximum capacity index, which can be represented by a formula. The maximum capability index or the maximum capacity index is related to at least one of the following input indicators: the maximum number of supported CCs; the aggregated bandwidth on each frequency band; the aggregated total bandwidth on all frequency bands; the bandwidth on each CC; the maximum number of MIMO layers; the numerology; and the modulation and demodulation manner. The input parameters of the formula can comprise at least one of the following: the maximum number of supported CCs; the aggregated bandwidth on each frequency band; the aggregated total bandwidth on all frequency bands; the bandwidth on each CC; the maximum number of MIMO layers; the numerology; and the modulation and demodulation manner.

[0056] In an embodiment, the first communication device supports a capability combination no higher than the maximum capability index or the maximum capacity index, i.e., the first communication device indicates any capability combination lower than or equal to the capability combination corresponding to the maximum capability index or the maximum capacity index.

[0057] In an embodiment, the association between the maximum capability index and the maximum capacity index and the input indicators is defined by a protocol or reported by the first communication device to the second communication device. In an example, the formula corresponding to the maximum capability index and the maximum capacity index can be defined by a protocol or pre-configured by the first communication device and reported to the second communication device. The second communication device can calculate and configure according to the same formula to ensure that the configured capability does not exceed the maximum capability index or the maximum capacity index reported by the first communication device.

[0058] In an embodiment, the maximum capability index and the maximum capacity index are output indicators, each of which comprises at least one of the following indicators: total computing power; storage capacity; storage space; process number; and thread number.

[0059] Secondly, distributed indicators are used, for example, the first communication device reports one or more multi-dimensional capability groups, so that the second communication device selects one of the groups to configure the capability of the first communication device. In an embodiment, the multi-dimensional capability group comprises at least one of the following: the maximum number of supported CCs; the aggregated bandwidth on each frequency band; the aggregated total bandwidth on all frequency bands; the bandwidth on each CC; the maximum number of MIMO layers; the numerology; and the modulation and demodulation manner. Assuming that the first communication device reports that the maximum number of supported CCs is 6, the second communication device needs to configure the number of CCs to be less than or equal to 6.

[0060] Thirdly, the first communication device reports the maximum capability supported by each CC corresponding to different number of CCs in an explicit manner. In an embodiment, the maximum capability supported by each CC includes at least one of the following: maximum MIMO layer number; numerology; modulation and demodulation mode.

[0061] In an embodiment, the reporting manner of the second capability set includes: dividing the frequency bands into corresponding frequency band pools according to the frequency band capability; and reporting the maximum capability supported by each frequency band pool. The first communication device can divide different frequency bands into corresponding frequency band pools according to the similarity of the frequency band capability, so that the frequency band capabilities in the same frequency band pool are the same or similar.

[0062] In an embodiment, each frequency band pool corresponds to one or more frequency band combination types; wherein the frequency band combination type is used to indicate the number of frequency bands contained in each frequency band combination, and the number of carriers on each frequency band. The frequency band combination type is used to indicate the number of frequency bands contained in the frequency band combination, and the number of carriers aggregated by the continuous carriers on each frequency band.

[0063] In an embodiment, the frequency band pool contains at least one frequency band or one or more frequency ranges with similar or same capability.

[0064] In an embodiment, the same frequency band or the same frequency range is contained in one or more frequency band pools.

[0065] In an embodiment, the first communication device supports no more than the maximum capability corresponding to the frequency band combination type. For the frequency band combination type reported by the first communication device, it also means that the first communication device can support any lower order or reduced order frequency band combination type thereof.

[0066] In an embodiment, any frequency band combination in each frequency band pool supports the corresponding frequency band combination type. Any frequency band combination in the frequency band pool can support the frequency band combination type corresponding to the frequency band pool.

[0067] In an embodiment, the first communication device further reports the following parameters to the second communication device: same frequency band information, different frequency band information, continuous carrier aggregation information and discontinuous carrier aggregation information in each frequency band combination type.

[0068] In an embodiment, the capability on each frequency band corresponding to different frequency band combination types is indicated in at least one of the following manners: explicit manner; implicit manner.

[0069] In an embodiment, in the case of indicating the capability on each frequency band corresponding to different frequency band combination types in an explicit manner, the capability on each frequency band corresponding to different frequency band combination types is directly indicated.

[0070] In an embodiment, in case of indicating the capability on each band corresponding to different band combination types in an implicit way, the indication is performed in one of the following granularities: the maximum capability supported by all bands in each band combination type; the maximum capability supported by all bands in all band combination types; the maximum capability supported by each band.

[0071] In an embodiment, the maximum capability supported by each band includes at least one of the following: the maximum number of CCs supported; the aggregated bandwidth on each band; the aggregated total bandwidth on all bands; the bandwidth on each CC; the maximum number of multiple-input multiple-output (MIMO) layers; numerology; modulation and demodulation scheme.

[0072] In an embodiment, for each band combination type of a band pool, the capability supported by each carrier in the band combination type can be reported. The capability supported by each carrier can include at least one of the following: the number of transmission ports, the number of reception ports, the number of MIMO layers supported, bandwidth information, modulation and demodulation scheme. The number of MIMO layers supported can include the number of uplink MIMO layers and the number of downlink MIMO layers. The bandwidth information can include uplink bandwidth information and downlink bandwidth information. The modulation and demodulation scheme can include uplink modulation and demodulation scheme and downlink modulation and demodulation scheme.

[0073] In an embodiment, the constraint information of the UE capability can be reported according to different reporting granularities. The reporting granularity includes one of the following: each carrier and band type of the band pool, all carriers and band types of the band pool, and multiple carriers in each band combination type. The constraint information includes at least one of the following: the maximum aggregated bandwidth, the total number of transmission ports, the total number of reception ports, the maximum number of MIMO layers, and the highest modulation and demodulation scheme. The maximum aggregated bandwidth, the maximum number of MIMO layers, and the highest modulation and demodulation scheme can also be divided into uplink and downlink.

[0074] When the reporting granularity is for each band combination type, the reported maximum aggregated bandwidth is the sum of the bandwidths supported by all carriers in each band combination type, the total number of transmission ports is the number of transmission ports on all carriers in each band and carrier combination type, the total number of reception ports is the sum of the number of reception ports on all carriers in each band and carrier combination type, the maximum number of MIMO layers is the maximum number of MIMO layers supported by a single carrier or the aggregated number of MIMO layers supported by all carriers in each band and carrier combination type, and the highest modulation and demodulation scheme is the highest modulation and demodulation scheme supported by a single carrier in each band and carrier combination type. The maximum aggregated bandwidth can include uplink maximum aggregated bandwidth and downlink maximum aggregated bandwidth. The maximum number of MIMO layers includes uplink maximum number of MIMO layers and downlink maximum number of MIMO layers. The highest modulation and demodulation scheme includes uplink highest modulation and demodulation scheme and downlink highest modulation and demodulation scheme.

[0075] When the reporting granularity is for each carrier in each band combination type, the maximum aggregated bandwidth is the sum of the bandwidths supported by the carriers, the total number of transmission ports is the number of transmission ports on the carriers, the total number of reception ports is the sum of the numbers of reception ports on the carriers, the maximum MIMO layer number is the maximum MIMO layer number supported by a single carrier in the carriers or the aggregated MIMO layer number supported by the carriers, and the highest modulation and demodulation mode is the highest modulation and demodulation mode supported by a single carrier in the carriers. The maximum aggregated bandwidth includes the uplink maximum aggregated bandwidth and the downlink maximum aggregated bandwidth. The maximum MIMO layer number includes the uplink maximum MIMO layer number and the downlink maximum MIMO layer number. The highest modulation and demodulation mode includes the uplink highest modulation and demodulation mode and the downlink highest modulation and demodulation mode.

[0076] When the reporting granularity is for all band combination types corresponding to the band pool, the maximum aggregated bandwidth is the sum of the bandwidths supported by all carriers in the band combination types, the total number of transmission ports is the number of transmission ports on all carriers in the band combination types, the total number of reception ports is the sum of the numbers of reception ports on all carriers in the band combination types, the maximum MIMO layer number is the maximum MIMO layer number supported by a single carrier in the band combination types 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 in the band combination types. The maximum aggregated bandwidth includes the uplink maximum aggregated bandwidth and the downlink maximum aggregated bandwidth. The maximum MIMO layer number includes the uplink maximum MIMO layer number and the downlink maximum MIMO layer number. The highest modulation and demodulation mode includes the uplink highest modulation and demodulation mode and the downlink highest modulation and demodulation mode.

[0077] Through the above operation, the bands are divided into corresponding band pools according to the band capability. Since the capabilities of the bands in the same band pool are the same or similar, the corresponding UE capability can be reported for the band pool, and it is not necessary to report the corresponding capability for each band or each band combination separately, thereby reducing the overhead of the UE capability reporting signaling.

[0078] In an embodiment, the decoupling combination criterion includes one of the following: a partially decoupled constraint rule; a fully decoupled constraint rule.

[0079] In an embodiment, the partial decoupling is to report the corresponding first capability set and the second capability set on different band pools, and the first capability set and the second capability set are one-to-one corresponding.

[0080] The complete decoupling is to report the corresponding second capability set on different frequency band pools, and the first capability set corresponding to different frequency band pools is the same, and the second capability set corresponding to different frequency band pools is different. In the case of partial decoupling, a corresponding first capability set and a second capability set are configured for each frequency band pool; in the case of complete decoupling, a plurality of frequency band pools correspond to the same first capability set, and each frequency band pool corresponds to a second capability set.

[0081] In an embodiment, the constraint rule between the first capability set and the second capability set is indicated in one of the following manners: a protocol specified manner, an implicit manner, and an explicit manner.

[0082] In an embodiment, in the case of indicating the constraint rule between the first capability set and the second capability set in the protocol specified manner, the constraint rule at least includes one of the following: a constraint rule of the maximum number of supported CCs, a bandwidth constraint rule, a maximum MIMO layer constraint rule, a modulation and demodulation manner constraint rule, and a numerology constraint rule. In an example, the first communication device reports the bandwidth constraint rule corresponding to the first capability set and the bandwidth constraint rule corresponding to the second capability set, so that the second communication device can jointly determine the corresponding bandwidth constraint rule according to the bandwidth constraint rule corresponding to the first capability set and the bandwidth constraint rule corresponding to the second capability set.

[0083] In an embodiment, in the case of indicating the constraint rule between the first capability set and the second capability set in the implicit manner, the constraint rule includes: classification information; wherein the classification information includes a classification identifier and / or a classification parameter corresponding to each classification identifier. When the first capability set and the second capability set supported by the first communication device are combined, the constraint rule indicated by the first communication device needs to be satisfied, such as satisfying the classification information.

[0084] In an embodiment, in the case of indicating the constraint rule between the first capability set and the second capability set in the explicit manner, the constraint rule includes: explicitly associating the first capability set and the second capability set. The first communication device can directly associate the first capability set with the second capability set, such as numbering the first capability set, and then associating the first capability set with the second capability set by indicating the number of the first capability set.

[0085] In an embodiment, FIG. 6 is a flowchart of another information reporting method provided by the embodiments of the present application. The present embodiment is applied to the case of separately reporting the radio frequency capability and the baseband capability of the UE.

[0110] In an embodiment, the partial decoupling is reporting the corresponding first capability set and second capability set for different frequency band pools, and the first capability set and the second capability set are one-to-one corresponding; the full decoupling is reporting the corresponding second capability set for different frequency band pools, and the first capability set corresponding to different frequency band pools is the same, and the corresponding second capability set is different.

[0111] In an embodiment, the constraint rule between the first capability set and the second capability set is indicated in one of the following manners: a protocol specified manner; an implicit manner; an explicit manner.

[0112] In an embodiment, in the case of indicating the constraint rule between the first capability set and the second capability set in the protocol specified manner, the constraint rule at least includes one of the following: a constraint rule of the maximum number of supported CCs; a bandwidth constraint rule; a maximum MIMO layer constraint rule; a modulation and demodulation manner constraint rule; a numerology constraint rule.

[0113] In an embodiment, in the case of indicating the constraint rule between the first capability set and the second capability set in the implicit manner, the constraint rule includes: classification information; wherein the classification information includes a classification identifier and / or a classification parameter corresponding to each classification identifier.

[0114] In an embodiment, in the case of indicating the constraint rule between the first capability set and the second capability set in the explicit manner, the constraint rule includes: explicitly associating the first capability set and the second capability set.

[0115] The explanations of the first capability set, the second capability set, the decoupling combination rule, the frequency band combination type, the frequency band pool and other parameters involved in the information reporting method applied to the second communication device are referred to the explanations of the corresponding parameters in the information reporting method applied to the first communication device described above, which will not be repeated here.

[0116] FIG. 7 is a UE capability architecture diagram based on a frequency band pool according to an embodiment of the present application. As shown in FIG. 7, different frequency bands are divided into multiple frequency band pools according to their similarity in capability. For example, the frequency band pool 1 includes frequency bands 1 to 4, and the frequency band pool 2 includes 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.

[0117] The frequency band combination type represents the combination type of the frequency bands supported by the frequency bands in the frequency band pool. Any frequency band combination in the frequency band pool supports the carrier combination type corresponding to the frequency band pool.

[0118] 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. 7, a carrier combination type corresponding to a 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 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).

[0119] The UE reports the corresponding UE capability by reporting the band combination type. For example, for a UE reporting a band combination type of {class A, class B, class C}, it also represents that the UE can support any one of the fallback band combination types, such as {class A}, {class B}, {class C}, {class A, class B}, {class A, class C}, {class B, class C}, and the like.

[0120] The UE further indicates at least one of the following information in the reported band combination type: same band information, different 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 band, and class C is a different band. The UE can also indicate how many different bands are included in a band combination type.

[0121] If some bands in a band pool have stronger capabilities than in the pool, they can also be reported separately.

[0122] 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:

[0123] Method one: explicit indication, i.e., for different carrier combination types, the specific capabilities on each band are indicated, such as bandwidth, the number of transmit ports, the number of receive ports, the number of MIMO layers, and the modulation and demodulation mode. These capabilities include uplink and downlink.

[0124] Method two: implicit or implicit and explicit combination, for example, the maximum aggregated bandwidth, the total number of transmit ports, the total number of receive ports, the maximum number of MIMO layers, and the highest modulation and demodulation mode are indicated. For example, there are 3 different granularities for this indication method

[0125] For each band type, the maximum aggregated bandwidth is the sum of the bandwidths supported by all carriers in the type, the total number of transmit / 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 mode is the highest modulation and demodulation mode supported by a single carrier.

[0126] For multiple carriers (such as a number of contiguous carriers in a band or aggregated carriers), the maximum aggregated bandwidth, the total number of transmit / receive ports, the maximum number of MIMO layers, and the highest modulation and demodulation mode can be defined for different classes (or different numbers of carriers).

[0127] For all band types, the capability reporting is independent of the specific band type, or the capability limit applies to all band types. The maximum aggregated bandwidth is the sum of the bandwidths supported by all carriers, the total number of transmit / 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 mode is the highest modulation and demodulation mode supported by a single carrier.

[0128] The indicated capabilities can include both uplink and downlink, for example, the bandwidth includes uplink bandwidth and downlink bandwidth, the number of uplink MIMO layers and the number of downlink MIMO layers, and the uplink modulation and demodulation mode and the downlink modulation and demodulation mode.

[0129] The band combination type can also be replaced by a band and carrier combination type or a carrier combination type. The band combination type can indicate the combination of bands in the band, and the carrier combination type can indicate the combination of carriers.

[0130] 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.

[0131] Table 1

[0132] 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.

[0133] In order to facilitate the understanding of the scheme provided by the present application, the frequency band combination type and the indication method of the specific capability are described below in combination with specific embodiments.

[0134] Embodiment one

[0135] This embodiment mainly describes the frequency band pool and the frequency band and carrier combination type supported by it

[0136] In the embodiment, the frequency band pool contains three frequency bands (band) respectively denoted as band 1, band 2, and band 3 (or three carriers, namely carrier 1, carrier 2, and carrier 3), and the carrier type corresponding to this pool has three types, denoted as Class A_Class B_Class C, Class C_Class C, and Class D. Figure 8 is a schematic diagram of a frequency band pool and the frequency band and carrier combination type supported by it provided by the embodiment of the present application, as shown in Figure 8, which means that the UE supports the following band combination (and the fallback combination, which is the combination left after deleting one or more carriers in the combination).

[0137] 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.

[0138] 2 Band combination: Band 1 Class C_Band 2Class C and Band 1 Class C_Band 3Class C and Band 1 2 Class C_Band 3 Class C.

[0139] 1 Band combination: Band 1 Class D and Band 2 Class D and Band 3 Class D.

[0140] Embodiment two

[0141] 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.

[0142] Table 2

[0143] 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.

[0144] Embodiment three

[0145] This embodiment mainly describes the band and carrier combination type and its supported specific capability indication, including implicit or implicit and explicit combination indication.

[0146] 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 the sum of the capabilities on all carrier units cannot exceed this constraint.

[0147] There are three different granularities for this indication method:

[0148] 1. For each carrier and band type.

[0149] 2. For multiple carriers (such as contiguous carriers on one band or aggregated number of carriers).

[0150] 3. For all carriers and band types.

[0151] For the first way, as shown in Table 3.

[0152] Table 3

[0153] For the second way, as shown in Table 4.

[0154] Table 4

[0155] For the third way, as shown in Table 5.

[0156] Table 5

[0157] 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 band combination type does not need to be reported specifically.

[0158] 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.

[0159] 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.

[0160] The first part: the baseband capability includes the following three independent reporting ways:

[0161] 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.

[0162] 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.

[0163] 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.

[0164] Table 6

[0165] Method three: Report the maximum capability of each CC under different CC numbers.

[0166] Second part: Separate reporting of radio frequency capability: Radio frequency capability is related to frequency band, and the reporting method can refer to the reporting method based on the frequency band pool (i.e. embodiments one to three) described above; in the reporting process of the above 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 radio frequency capability, and if the capability is integrated with the baseband and radio frequency, it can be regarded as the unified reporting of radio frequency capability and baseband capability.

[0167] Third part: decoupling combination criterion 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 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 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, etc. may also be different, so according to whether the specific frequency band is divided, there are two reporting modes as follows:

[0168] 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. 9 is a configuration schematic diagram of constraint rules of frequency band capability and baseband capability in a partial decoupling scene according to an embodiment of the present application. As shown in FIG. 9, in the same frequency band pool, the baseband capability and the radio frequency capability are one-to-one corresponding.

[0169] The rules can be embodied in two ways:

[0170] 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,

[0171] 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:

[0172] Class A_Class B_Class C is (6CC), so the baseband capability matched therewith should at least contain 6 carriers; for the bandwidth constraint rule, 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.

[0173] For the constraint rule of maximum MIMO layer, for example, the corresponding antenna port is 2 Rx, then the corresponding baseband capability can only be 2 layers of MIMO.

[0174] For the constraint rule of modulation / demodulation, for example, when matching the corresponding baseband capability for the radio frequency capability, the corresponding modulation / demodulation should be supported in the baseband capability.

[0175] Method two: UE implicit indication, that is, UE reports the adaptation constraint of the corresponding baseband capability and radio frequency capability, for example, UE can indicate the different classification information of the supported capability, and the network needs to comply with the constraint rules of these classification information when configuring the UE, and these classification information can include the number of CCs, bandwidth, MIMO layer / transmit / receive antenna port number, modulation / demodulation order or UE power class, etc. dimensions for definition.

[0176] In these classification information, both the radio frequency capability and the baseband capability are included.

[0177] In an example, FIG. 10 is a configuration diagram of the classification information of the frequency band capability and the baseband capability in the partial decoupling scene provided by the embodiment of the application. In this example, the UE can report its supported classification information, that is, the classification information (Category information) in FIG. 10, which can be defined in the granularity of the whole UE, or can be defined based on each band pool. The UE can report the category class it supports 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.

[0178] 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 by indicating the number of the baseband capability, as shown in Table 7.

[0179] Table 7

[0180] Wherein, x, y, z represent different baseband capabilities.

[0181] Note: In the above scheme, the classification information supported in different carriers / frequency band groups / pools can be the same; in the above figure, the elements of the baseband and the radio frequency capability can be partially the same in different carriers / frequency band groups / pools, so the baseband and the radio frequency capability pool can be defined, and then referenced by the index scheme in each carrier / frequency band group / pool.

[0182] The elements of baseband and radio frequency capability in the above diagram can only contain uplink or only contain downlink, or contain both uplink and downlink.

[0183] The second reporting mode: 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 partial decoupling described above.

[0184] FIG. 11 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 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 at the same time, and for mode two, the supported classification constraint is also reported.

[0185] In an example, the solution is optimized for carrier concatenation:

[0186] FIG. 12 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 12, 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. Under 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.

[0187] FIG. 13 is a configuration diagram of a constraint rule between baseband capability and radio frequency capability according to an embodiment of the present application. As shown in FIG. 13, similar techniques are adopted under this architecture, 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 ways described above.

[0188] Under 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 ways described above.

[0189] The reporting can be based on a frequency band pool or the entire UE.

[0190] FIG. 14 is a schematic diagram of uplink and downlink decoupling according to related technologies. As shown in FIG. 14, in order to meet the demand for more flexible uplink and downlink carrier pairing, 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:

[0191] There is no band limitation 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 band or in different bands.

[0192] There is no limitation 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.

[0193] There is no limitation between the scheduling relationship and the feedback relationship between the uplink carriers and the downlink carriers. Any one downlink carrier can schedule any one or more uplink carriers, and any one uplink carrier can feed back the feedback information of any one or more downlink carriers.

[0194] 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.

[0195] In the following embodiments, the first communication device is taken as the UE, and the second communication device is taken as the network side as an example to explain the decoupling reporting process of the uplink and downlink capability. The uplink capability set can also be referred to as the uplink capability, and the downlink capability set can also be referred to as the downlink capability.

[0196] 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. The solution of uplink and downlink decoupling reporting contains three parts: uplink capability independent reporting; downlink capability independent reporting; combination criteria after uplink and downlink decoupling (i.e. decoupling combination criteria).

[0197] Here, according to whether the radio frequency and baseband capability is decoupled, it can be further divided into two categories for discussion: radio frequency capability and baseband capability decoupling; radio frequency capability and baseband capability do not decouple.

[0198] FIG. 15 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 application, as shown in FIG. 15:

[0199] 1) In the above FIG. 15, the downlink frequency band pool (DL band pool) can have only one, and the uplink frequency band pool (UL band pool) can also have only one, and the two pools can also be the same.

[0200] 2) Different band pools can also have different uplink and downlink radio frequency capabilities. This logic is similar to the previous description, and will not be repeated here.

[0201] Figure 16 is an implementation schematic diagram of the uplink and downlink decoupling of baseband capability provided by the embodiment of the application. As shown in Figure 16, for the uplink and downlink decoupling of baseband capability: in the implementation of baseband, the uplink capability and the downlink capability are generally implemented independently, and there can be no certain constraint 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 total storage requirement of uplink and downlink can be constrained within a certain limit.

[0202] The constraint can be specified by a protocol or indicated by a UE. The UE indication can consider the following three constraint methods:

[0203] Total computing power constraint information, i.e. total computing power of uplink and downlink, is similar to the aforementioned reporting of maximum baseband capability index or maximum capacity index. The index is calculated by a formula, and the input parameters of the formula can include the number of CCs, bandwidth (which can be the total loan aggregation, the total bandwidth aggregation on each band, the bandwidth on each CC, etc.), the number of maximum MIMO layers (or the sum of the number of MIMO layers), numerology, etc.

[0204] 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 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; the maximum capability index or maximum capacity index can include multiple output indicators such as computing power, storage capacity / space, process / thread number, etc.

[0205] The UE reports its category constraint, for example, the UE reports the supported category. The category information contains both uplink information and downlink information.

[0206] Display indication, i.e. display indication of which uplink capability and which downlink capability can be matched, as shown in Table 8.

[0207] Table 8

[0208] For the uplink and downlink decoupling of radio frequency capability: since the uplink and downlink cannot be completely independent like the baseband chip when designing the radio frequency chip, there is a certain coupling, and there are the following methods:

[0209] Figure 17 is a configuration diagram of radio frequency capability of the same frequency band pool according to an embodiment of the present application. As shown in Figure 17, similar to the foregoing, bands or carriers with similar attributes can be placed in a band carrier group, which means that uplink and downlink can be matched within the band carrier group.

[0210] Figure 18 is a configuration diagram of radio frequency capability of the different frequency band pool according to an embodiment of the present application. As shown in Figure 18, for some bands, if they only support downlink or uplink carriers, the band carrier group supporting uplink can be inconsistent with the band carrier group supporting downlink, and one or more uplink carrier groups, one or more downlink carrier groups, and corresponding coupling relationships can be defined.

[0211] In the above description, the constraints between the uplink and downlink band carrier pools can be as follows:

[0212] (1) conform to the protocol definition, that is, only the uplink and downlink band carrier pools defined in the protocol can be combined.

[0213] (2) the uplink and downlink carrier pools contain at least the same band or carrier / frequency range (TDD).

[0214] (3) display indication, for example, indicating which downlink band carrier pool can be paired with which uplink band carrier pool.

[0215] In the above description, the constraints between the uplink and downlink radio frequency capabilities can be as follows:

[0216] (1) the UE indicates its supported categories, and the category information contains supported uplink and downlink carrier / band combination types, 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.

[0217] (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.

[0218] (3) display indication, for example, indicating which downlink radio frequency capability can be paired with which uplink radio frequency capability.

[0219] Figure 19 is a 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 Figure 19.

[0220] In this architecture, the constraints between the uplink and downlink frequency band carrier pools are the same as before, and the reporting manner of the constraints between the uplink and downlink frequency band carrier pools is also similar to before, the only 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:

[0221] (1) The UE indicates its supported categories, which contain supported uplink and downlink carrier / band combination types, 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.

[0222] (2) Total computing power constraints, including baseband computing power, radio frequency computing power, or the sum of the two.

[0223] (3) Display indication, such as indicating which downlink radio frequency capability can be paired with which uplink radio frequency capability.

[0224] In an embodiment, FIG. 20 is a structural block diagram of an information reporting device provided by an embodiment of the present application. The present embodiment is applied to a first communication device. As shown in FIG. 20, the information reporting device in the present embodiment includes a decoupler 310 and a transmitter 320.

[0225] The decoupler 310 is configured to decouple the UE capability into a first capability set and a second capability set; the transmitter 320 is configured to report the first capability set and the second capability set to a second communication device.

[0226] In an embodiment, the information reporting device applied to the first communication device further includes:

[0227] The transmitter 320 is further configured to report decoupling combination criteria between the first capability set and the second capability set to the second communication device.

[0228] In an embodiment, the first capability set includes related capabilities of baseband processing in the UE; and the second capability set includes related capabilities of radio frequency processing in the UE.
