Figure 1As shown, the communication system may include terminal device 150 and network device 160. This communication system can be used to support 4G network access technologies, such as Long Term Evolution (LTE) access technology, or 5G network access technologies, such as New Radio Access Technology (New RAT), or other future wireless communication technologies. It should be noted that in this communication system, the number of network devices and terminal devices can both be one or more. Figure 1 The number of network devices and terminal devices in the communication system shown is merely an adaptive example, and this disclosure does not limit this number.

[0042] In some embodiments, Figure 1The network device 160 may include devices for supporting terminal device access and providing wireless network communication functions for the terminal device. In some embodiments of this disclosure, the network device may include access network devices and / or core network devices. The access network device may be a RAN (Radio Access Network) or AN (Access Network). For example, the access network device may be an evolved Node B (eNB or eNodeB) in LTE; the access network device may also be a next-generation Node B (gNB or gNodeB) in a 5G network; the access network device may also be an NG Radio Access Network (NG-RAN) device in a 5G network; the access network device may also be a base station, Broadband Network Gateway (BNG), aggregation switch, or non-3GPP (3rd Generation Partnership Project) access device in a future evolved Public Land Mobile Network (PLMN). Optionally, the access network equipment in this disclosure may include various forms of base stations, such as macro base stations, micro base stations (also known as small stations), relay stations, access points, 5G base stations or future base stations, satellites, Transmitting and Receiving Points (TRPs), Transmitting Points (TPs), mobile switching centers, and equipment that performs base station functions in device-to-device (D2D), machine-to-machine (M2M), Internet of Things (IoT), vehicle-to-everything (V2X), or other communications. This disclosure does not specifically limit these. For ease of description, in the embodiments of this disclosure, the apparatus that provides wireless communication functions for terminal devices is collectively referred to as access network equipment or base station. This core network equipment can be used to perform one or more of the following functions on terminal devices: mobility management, call control, session management, registration and authentication, and billing. The core network equipment may include one or more entities, which may be hardware, software functionally defined, or a combination of both. It should be noted that this entity may also be referred to as a function.

[0043] The relevant technologies will be further introduced below:

[0044] In related technologies, the configuration of terminal communication rate is achieved through MCS (Modulation and Coding Scheme) index values. The MCS uses the factors affecting communication rate as columns and the MCS index as rows, forming a rate table, or index table. The MCS defines the number of effective bits that a Resource Element (RE) can carry. There are 0-31 MCS schemes, with schemes 29-31 reserved. A higher MCS index results in a higher number of effective bits. The choice of which MCS to use depends on the quality of the radio link. Better quality allows for a higher MCS, meaning more useful bits can be transmitted per symbol. Poor signal quality necessitates choosing a lower MCS index, meaning less useful data can be transmitted per symbol. Specifically, network devices can select the MCS based on the Block Error Rate (BLER). Network devices can use link adaptive algorithms to allocate MCS, ensuring that the BLER does not exceed a threshold under different radio conditions.

[0045] Furthermore, the related technology provides three index tables for terminals to choose from for PUSCH (Physical Uplink Shared Channel): a 64QAM (Quadrature Amplitude Modulation) table, a 256QAM table, and a low-spectrum-efficiency 64QAM table. Specifically, the 64QAM index table can be used when the network device or terminal does not support 256QAM or the channel is poor, the 256QAM table cannot be decoded successfully, and the network device needs to use Quadrature Phase Shift Keying (QPSK) modulation. When the channel condition is good and the device supports 256QAM, the 256QAM table can be used. The low-spectrum-efficiency 64QAM table is suitable for applications requiring reliable data transmission, such as URLLC (Ultra-Reliable Low-Latency Communications) applications. MCS improves channel reliability by reducing the coding rate and increasing channel coding redundancy, thus resulting in lower spectral efficiency.

[0046] The choice of which MCS index table a terminal uses and which MCS index it employs can be determined by the network device based on a link adaptation algorithm. For example, the network device can indicate the MCS index table to the terminal via RRC signaling. After indicating the index table, the network device can use DCI (Downlink Control Information) to provide the terminal with the selected MCS configuration information.

[0047] Some terminals do not support all MCS indices under the supported modulation schemes. However, in related technologies, terminals can only report the modulation schemes they support to the network device, but cannot report the MCS indices they support, which causes some terminals to fail to obtain the expected gain for some index values.

[0048] For example, in related technologies, when a terminal reports that it supports 256QAM via the information element PUSCH-256QAM, it indicates that the terminal supports the MCS index corresponding to all 256QAM modulations. However, in FR2 (Frequency range 2), when the terminal supports UL256QAM, it is found through link simulation that for high MCS indices, 256QAM cannot obtain the expected gain compared to UL 64QAM.

[0049] Based on this, in one embodiment, such as Figure 1 In the communication system shown, the network device can be a base station, and the terminal device can be a terminal. The base station can be used to execute the steps of the capability reporting method executed on the network device side in the following embodiments, and the terminal can be used to execute the steps of the capability reporting method executed on the terminal side in the following embodiments. This enables the terminal to report its supported MCS index values, and further enables the base station to more accurately configure the MCS for the terminal, so that the terminal can perform modulation based on its supported MCS index values.

[0050] In one specific embodiment, when a terminal reports the supported modulation schemes to a network device, such as a base station, it can report the index value of the supported MCS per band.

[0051] In one possible implementation, when a terminal cannot obtain the expected gain by using high MCS index values ​​in the 256QAM index table in FR2, when the terminal reports that it supports UL 256QAM through the existing information element PUSCH-256QAM, the terminal can further indicate which MCS indexes in the 256QAM index table it specifically supports through a new information element, which can specifically indicate which index values ​​in MCS indexes 20-27 supported by the terminal.

[0052] In another possible implementation, to facilitate the extension of this reporting capability to other existing high-order modulation schemes, the new information element can be defined as an enumeration signaling, reporting the index value of a modulation scheme supported by the terminal at a time. This new information element can correspond to any one of 256QAM, 64QAM, and low spectral efficiency 64QAM. The terminal can determine which modulation scheme it corresponds to by selecting the parameters in this information element.

[0053] Furthermore, if the aforementioned new information elements are missing and not reported, it indicates that the terminal supports all MCS index values ​​in the corresponding MCS index table.

[0054] Furthermore, the MCS index allocated by the network device using the link adaptation algorithm can be within the range of the index reported by the terminal. In other words, the MCS index value indicated by the MCS configuration information sent by the network device to the terminal can be determined based on the MCS index value reported by the terminal.

[0055] Based on the above overall inventive concept, this disclosure also provides the following embodiments:

[0056] Figure 2 This is a flowchart illustrating a capability reporting method according to an exemplary embodiment, the method being applied to a terminal, such as... Figure 2 As shown, the method includes:

[0057] S201. The terminal sends its capability information to the network device. This capability information indicates the MCS index values ​​supported by the terminal on one or more frequency bands. The MCS index values ​​include some or all of the MCS index values ​​from one or more MCS index tables.

[0058] The capability information can be carried via PUSCH or other uplink signals. In some possible implementations, the capability information may also include other information to indicate other capabilities of the terminal, such as the terminal's current load, its own processing capabilities, and the MCS index table it supports, etc., which are not specifically limited in this disclosure. In addition, the MCS index value used to indicate the terminal's support on one or more frequency bands can be the aforementioned capability information, or any other information, such as UCI (Uplink Control Information), etc., which are not limited in name in this disclosure.

[0059] It should be noted that the MCS index values ​​supported by the terminal can refer to the MCS index values ​​that enable the terminal to obtain the expected gain, or the MCS index values ​​whose gain meets preset conditions. For example, some MCS index values ​​not included in the capability information can be MCS index values ​​that the terminal does not support.

[0060] In addition, an MCS index value can also be described as an MCS index or an MCS value, and an MCS index table can also be described as an MCS table or an MCS table, etc. This disclosure does not limit the name.

[0061] In one embodiment, the MCS index table supported by the terminal can specifically refer to the MCS index table supported by the terminal on one or more frequency bands corresponding to the capability information. Optionally, if the terminal supports a certain MCS index table, it means that the terminal supports the modulation scheme corresponding to that index table, and vice versa.

[0062] In one example, the MCS index value indicated by the capability information includes some or all of the MCS index values ​​in the MCS index table supported by the terminal.

[0063] For example, after a terminal determines that it supports a certain MCS index table in a certain frequency band, it can determine the index value with better gain in the supported MCS index table based on its own capabilities or the quality of the wireless link, and indicate these index values ​​to the network device through capability information.

[0064] As another example, if the capability information includes MCS index values ​​corresponding to MCS index tables that the terminal does not support, the network device can discard or ignore these index values ​​after receiving the capability information. For instance, if the network device determines that the terminal does not support the 256QAM index table based on information previously reported by the terminal device, the network device can discard or ignore these index values ​​even if it receives the index values ​​corresponding to 256QAM.

[0065] In one embodiment, the capability information can specifically be used to indicate the index values ​​supported by the terminal in each frequency band, or it can be used to indicate the index values ​​supported by the terminal in a certain frequency band. Correspondingly, the MCS index values ​​supported by the terminal can be the MCS index values ​​supported by the terminal in each frequency band, or it can be the MCS index values ​​supported by the terminal in a certain frequency band. In one embodiment, the terminal can also indicate the MCS index values ​​supported by the terminal in each frequency band by sending the capability information multiple times. In some embodiments, the MCS index value can be represented as I. MCS The index value can range from 0 to 31. In the same index table, a higher index value means more useful bits can be transmitted in a single symbol, indicating higher signal quality. 29-31 can be reserved indexes. In some embodiments, which index values ​​a terminal specifically supports can be determined based on its own capabilities, network device capabilities, and / or the quality of the wireless link. For example, if the terminal does not support MCS index 26 in the 256QAM index table, then the MCS index values ​​indicated by the capability information may not include MCS index 26.

[0066] In one example, the terminal supports one or more of the following MCS index tables: 256QAM index table, 64QAM index table, and low spectral efficiency 64QAM index table.

[0067] In some embodiments, the specific index tables supported by the terminal can be determined based on its own capabilities, network device capabilities, and / or the quality of the wireless link. Furthermore, in addition to the index tables mentioned above, the MCS index tables supported by the terminal may also include 2048QAM index tables if other index tables are defined or if the terminal and network devices are further improved with technological advancements, such as supporting 2048QAM modulation. Correspondingly, the MCS index values ​​indicated by the capability information may further include index values ​​from the 2048QAM index table.

[0068] In one example, capability information is also used to indicate the MCS index tables supported by the terminal.

[0069] Alternatively, in another example, the method further includes, before sending the terminal's capability information to the network device:

[0070] Send the MCS index table supported by the terminal to the network device.

[0071] For details regarding the steps of sending the MCS index table supported by the terminal to the network device, please refer to [reference needed]. Figure 4 The detailed description of step S401 shown is not repeated here.

[0072] For example, the MCS index table supported by the terminal can be reported to the network device via other signaling or information elements, or it can be reported to the network device through this capability information. That is, if the terminal determines that it supports a certain MCS index table, it can send information indicating the MCS index table it supports in advance before sending the capability information, or it can also carry information indicating the MCS index table it supports through the capability information.

[0073] For example, capability information can also be used to indicate the MCS index tables supported by the terminal and the corresponding MCS index values ​​for those tables. The information element indicating the MCS index tables supported by the terminal and the information element indicating the MCS index values ​​supported by the terminal can be different.

[0074] For example, in related technologies, PUSCH-256QAM is an existing information element. A terminal can use this existing information element, PUSCH-256QAM, to report its support for UL 256QAM. That is, the terminal can inform the network device that it supports the 256QAM index table by reporting this PUSCH-256QAM information element. Upon receiving this PUSCH-256QAM information element, the network device can determine whether the terminal supports the 256QAM index table. As another example, the terminal can also pre-report the ul-64QAM-MCS-TableAlt information element, which can be used to indicate whether the terminal supports the low spectral efficiency 64QAM index table. Alternatively, the terminal can pre-report PUSCH-256QAM to indicate its support for UL 256QAM.

[0075] In an optional embodiment, the PUSCH-256QAM information element can be carried by the capability information. The capability information can indicate that the terminal supports the UL 256QAM modulation method, i.e., the 256QAM index table, and supports the MCS index 0-15, 0-27, or 20-27 in the 256QAM index table. This disclosure does not limit the specific value of the MCS index supported by the terminal indicated by the capability information, and the terminal can set it according to the actual situation.

[0076] In one embodiment, the MCS index value indicated by the capability information may include index values ​​from the 256QAM index table. For example, if the MCS index value indicated by the capability information includes index values ​​from the 256QAM index table, i.e., the terminal supports index values ​​from the 256QAM index table in the corresponding frequency band, and the terminal has previously reported that it supports the 256QAM index table, the network device can determine that the terminal can support these index values. If the terminal does not report its support for the 256QAM index table, or if the terminal reports that it does not support the 256QAM index table, the network device can discard or ignore these MCS index values. In another embodiment, if the terminal also supports 64QAM or low-spectrum-efficiency 64QAM modulation schemes, i.e., the terminal supports the 64QAM index table or the low-spectrum-efficiency 64QAM index table, the MCS index value reported by the terminal may also include some or all of the MCS index values ​​from the 64QAM index table or the low-spectrum-efficiency 64QAM index table.

[0077] In one example, the capability information includes one or more capability information elements, each capability information element corresponds to a first MCS index table, and each capability information element includes the MCS index value supported by the terminal in the corresponding first MCS index table.

[0078] For example, the capability information element can be a newly defined information element compared to related technologies. The capability information may include multiple capability information elements, and one capability information element may correspond to a modulation scheme, i.e., an MCS index table. For example, one capability information element may correspond to a 256QAM index table, and another capability information element may correspond to a 64QAM index table.

[0079] In one embodiment, the first MCS index table is an MCS index table supported by the terminal.

[0080] In other words, the terminal supports the MCS index table corresponding to each capability information element reported by the terminal.

[0081] For example, if the terminal supports 256QAM index table and 64QAM index table, when the capability information includes capability information elements corresponding to 64QAM, the capability information elements can be used to indicate the index value in the 64QAM index table supported by the terminal. When the capability information includes capability information elements corresponding to 256QAM, the capability information elements can be used to indicate the index value in the 256QAM index table supported by the terminal.

[0082] In one embodiment, the MCS index value indicated by the capability information element may include all or part of the index values ​​in the index table corresponding to the capability information element. For example, if the terminal supports all index values ​​in the 256QAM index table, the terminal can send the capability information element corresponding to the 256QAM index table, and the index value indicated by the capability information element may include all index values ​​in the 256QAM index table. Alternatively, if the terminal supports some index values ​​in the 256QAM index table, the terminal can send the capability information element corresponding to 256QAM, and the index value indicated by the capability information element may include some of the index values ​​in the 256QAM index table that the terminal supports.

[0083] In another embodiment, the first index table may not be an MCS index table supported by the terminal. For example, if the capability information includes capability information elements corresponding to an MCS index table not supported by the terminal, the network device may discard or ignore such capability information elements after receiving them. For instance, if the network device determines that the terminal does not support the 256QAM index table based on information previously reported by the terminal device, the network device may discard or ignore the capability information elements corresponding to 256QAM even if it receives them.

[0084] In one example, when the capability information does not include the capability information element corresponding to the second MCS index table, the capability information is used to indicate that the terminal supports all MCS index values ​​in the second MCS index table; the second index table is the MCS index table supported by the terminal.

[0085] For example, if a terminal supports all index values ​​in the 256QAM index table, the terminal may not need to send the corresponding capability information element for 256QAM. For instance, if a terminal lacks the capability to send the capability information element corresponding to the 256QAM index table or has not configured the relevant capability, but the terminal determines that it supports the 256QAM modulation scheme or all index values ​​in the 256QAM index table, and is unable to send capability information including that capability information element, the network device can still determine that the terminal supports the 256QAM modulation scheme based on this capability information, and thus can configure the index value in the 256QAM index table for it.

[0086] Optionally, if the terminal supports all index values ​​corresponding to a certain index table, the terminal may send the capability information element corresponding to the index table or may not send the capability information element corresponding to the index table. Those skilled in the art can set this according to their actual needs, or the terminal can determine it according to its own capabilities. This disclosure does not limit this.

[0087] In one instance, the capability information element can be defined as follows:

[0088]

[0089] In one embodiment, the capability information element can be named MinMaxMCS-Config-UL-256QAM-r18. The SEQUENCE parameter corresponding to this information element can be used to indicate the frequency band corresponding to the capability information element. The parameter corresponding to MinMCS-PUSCH-r18 is the minimum index value, and the parameter corresponding to MaxMCS-PUSCH-r18 is the maximum index value. The minimum index value can be any integer from 0 to 27, and the maximum index value can be any integer from 0 to 31. For example, after receiving this capability information element, the network device can determine the index value in the 256QAM index table supported by the terminal based on the maximum and minimum index values.

[0090] This capability information element can only correspond to the 256QAM index table. In one implementation, if the terminal supports 256QAM modulation, 64QAM modulation, and low spectral efficiency 64QAM, it can be assumed that the terminal supports all index values ​​in the 64QAM index table and all index values ​​in the low spectral efficiency 64QAM index table. The terminal can then indicate which specific index values ​​in the 256QAM index table it supports by reporting this capability information element, or it can indicate that the terminal supports all index values ​​in the 256QAM index table by not reporting this capability information element.

[0091] In this example, when the terminal supports UL 256QAM modulation, it can further indicate the MCS index value in the 256QAM index table supported by the terminal by sending the capability information element while reporting the PUSCH-256QAM.

[0092] In another example, the capability information element can be defined as follows:

[0093]

[0094] In some embodiments, the capability information element can be named MinMaxMCS-Config-r18. The SEQUENCE parameter corresponding to this information element can be used to indicate the frequency band corresponding to the capability information element, and the parameter corresponding to MCS-Table-r18 can be used to indicate the index table corresponding to the capability information element. This signaling is an enumeration signaling, and can only report one modulation scheme at a time. For example, when MCS-Table-r18 = qam64, this indicates that the capability information element corresponds to 64QAM; when MCS-Table-r18 = qam256, this indicates that the capability information element corresponds to 256QAM; and when MCS-Table-r18 = qam64LowSE, this capability information element corresponds to low spectral efficiency 64QAM. Furthermore, the parameter corresponding to MinMCS-PUSCH-r18 is the minimum index value, and the parameter corresponding to MaxMCS-PUSCH-r18 is the maximum index value. The minimum index value ranges from 0 to 27, and the maximum index value ranges from 0 to 31. For example, after receiving the capability information element, the network device can determine the index value in the 256QAM index table supported by the terminal based on the maximum and minimum index values.

[0095] In some optional embodiments, since the terminal is more likely to experience signal modulation failure to achieve the expected gain for high MCS indices, the capability information can be specifically used to indicate the high MCS indices supported by the terminal. Here, a high MCS index can refer to an MCS index with an index value higher than a preset threshold. For example, with a preset threshold of 20, if the terminal supports 256QAM modulation, it can be assumed that the terminal can support MCS index values ​​0-19 in the 256QAM index table, and the capability information only needs to indicate which index values ​​from 20-27 in the 256QAM index table the terminal supports. Furthermore, in one possible implementation, the minimum index value in the capability information element can be defaulted to 0, and the maximum index value can range from a preset threshold to 31 or from a preset threshold to 27.

[0096] Furthermore, a terminal can transmit capability information multiple times for the same frequency band. Each transmission of capability information may include different index tables corresponding to the capability information elements, indicating the supported index values ​​of the terminal across multiple index tables. The network device can configure the MCS configuration information only after confirming that it has received capability information corresponding to all index tables supported by the terminal for the corresponding frequency band. For example, if the terminal supports 64QAM, 256QAM, and low-spectrum-efficiency 64QAM, and none of the multiple capability information transmissions for the same frequency band include the corresponding 64QAM capability information element, then the terminal supports all index values ​​corresponding to the 64QAM index table. Similarly, if none of the multiple capability information transmissions include the corresponding low-spectrum-efficiency 64QAM capability information element, then the terminal supports all index values ​​corresponding to the low-spectrum-efficiency 64QAM index table.

[0097] In one example, the terminal supports frequency range 2, or FR2 (Frequency range 2).

[0098] For example, the terminal could be an F2 terminal, and an FR2 terminal could be any terminal supporting millimeter-wave frequency bands between 24.25 GHz and 71 GHz. Referring to relevant technologies, in FR2, when the terminal supports UL 256QAM, link simulation revealed that for high MCS indices, 256QAM cannot achieve the expected gain compared to UL 64QAM. Therefore, by sending capability information indicating the MCS index supported by the terminal, the terminal can effectively ensure that the FR2 terminal achieves the expected gain with 256QAM.

[0099] In one example, after executing step S201, the terminal may also execute the following steps: the terminal receives MCS configuration information sent by the network device, the MCS configuration information being used to configure the MCS index values ​​supported by the terminal on one or more frequency bands.

[0100] For a detailed description of this step, please refer to [link / reference]. Figure 3 The detailed description of step S302 shown is not repeated here.

[0101] In this embodiment of the disclosure, the terminal sends capability information indicating the MCS index values ​​supported by the terminal. The MCS index values ​​indicated by the capability information may only include the index values ​​supported by the terminal, which can more accurately report the terminal capabilities and avoid the terminal not obtaining the expected gain for some index values ​​corresponding to its supported modulation methods, thus ensuring the reliability of transmission.

[0102] Where there is no contradiction, the embodiments disclosed herein can be combined with other embodiments or implementation methods and their various optional solutions involved in capability reporting methods, which will not be elaborated here.

[0103] Figure 3 This is a flowchart illustrating a capability reporting method according to an exemplary embodiment, the method being applied to a terminal, such as... Figure 3 As shown, the method includes:

[0104] S301. The terminal sends its capability information to the network device. The capability information is used to indicate the MCS index values ​​supported by the terminal on one or more frequency bands. The MCS index values ​​include some or all of the MCS index values ​​in one or more MCS index tables.

[0105] For details regarding step S301, please refer to [link / reference]. Figure 2 The detailed description of step S201 shown will not be repeated here.

[0106] S302. The terminal receives MCS configuration information sent by the network device. The MCS configuration information is used to configure the MCS index values ​​supported by the terminal on one or more frequency bands.

[0107] The information used to configure the MCS index values ​​supported by the terminal on one or more frequency bands can be the aforementioned MCS configuration information, MCS index indication information, or DCI. This disclosure does not limit the name.

[0108] For example, after receiving the MCS configuration information, the terminal can modulate and transmit signals on the corresponding frequency band according to the MCS index value indicated by the MCS configuration information, ensuring that the MCS index value configured in the MCS configuration information is an MCS index value supported by the terminal.

[0109] In one embodiment, the MCS configuration information can be used to indicate the modulation method of the signal selected by the terminal, and can specifically be used to indicate the MCS index table and MCS index value used by the terminal.

[0110] For example, the MCS configuration information may be carried by DCI and / or RRC signaling.

[0111] For example, the MCS index table can be indicated by the PDSCH (Physical Downlink Shared Channel)-Config and SPS (Semi-Persistent Scheduling)-Config parameters in the RRC signaling, thereby enabling the terminal to perform modulation based on the MCS index table indicated by the MCS configuration information.

[0112] For example, the MCS index value used by the terminal can be dynamically configured via DCI. For instance, if the network device determines a change in the quality of the wireless link with the terminal, it can reconfigure the MCS configuration information based on the terminal's capability information and send it to the terminal via DCI. This allows the terminal to perform signal modulation on the corresponding frequency band based on the dynamically indicated MCS index value via DCI.

[0113] Optionally, the MCS index value configured in the MCS configuration information can be determined based on the MCS index values ​​supported by the terminal as indicated by the capability information, so that the MCS index value corresponding to the MCS configuration information is within the range of MCS index values ​​reported by the terminal. For example, if the capability information indicates that the terminal supports MCS index values ​​0-15 in the 256QAM index table, the MCS configuration information can instruct the terminal to use MCS index values ​​0-15, 0-10, or 10-15 in the 256QAM index table for signal modulation.

[0114] In some other possible implementations, the MCS configuration information may specifically be configured by the core network equipment and sent to the base station, and then further sent to the terminal by the base station.

[0115] In this embodiment of the disclosure, the terminal can more accurately report its capabilities by sending capability information indicating the MCS index values ​​it supports and receiving MCS configuration information configured by the network device based on the capability information. This enables the network device to configure the MCS based on the terminal's capabilities, avoiding the terminal failing to obtain the expected gain for some index values ​​corresponding to its supported modulation methods, and ensuring the reliability of transmission.

[0116] Where there is no contradiction, the embodiments disclosed herein can be combined with other embodiments or implementation methods and their various optional solutions involved in capability reporting methods, which will not be elaborated here.

[0117] Figure 4 This is a flowchart illustrating a capability reporting method according to an exemplary embodiment, the method being applied to a terminal, such as... Figure 4 As shown, the method includes:

[0118] S401. The terminal sends the MCS index table supported by the terminal to the network device.

[0119] In one embodiment, the terminal may further send an MCS index table that the terminal supports on one or more frequency bands.

[0120] For example, the MCS index tables supported by the terminal can be reported to the network device via other signaling or information elements, such as UCI. Thus, if the terminal determines that it supports a certain MCS index table, it can pre-send information indicating the supported MCS index tables before sending capability information, allowing the network device to configure the terminal's modulation scheme based on the supported index tables.

[0121] S402. The terminal sends its capability information to the network device. The capability information is used to indicate the MCS index values ​​supported by the terminal on one or more frequency bands. The MCS index values ​​include some or all of the MCS index values ​​in one or more MCS index tables.

[0122] For details regarding step S402, please refer to [link / reference]. Figure 2 The detailed description of step S201 shown will not be repeated here.

[0123] In this embodiment of the disclosure, the terminal sends the MCS index table it supports and capability information indicating the MCS index values ​​it supports. This allows the network device to more accurately know the MCS index table it supports and the MCS index values ​​it supports. As a result, the network device can perform more reliable MCS configuration based on the terminal's capabilities, avoiding the terminal failing to obtain the expected gain for some index values ​​corresponding to its supported modulation methods, thus ensuring the reliability of transmission.

[0124] Where there is no contradiction, the embodiments disclosed herein can be combined with other embodiments or implementation methods and their various optional solutions involved in capability reporting methods, which will not be elaborated here.

[0125] Figure 5 This is a flowchart illustrating a capability reporting method according to an exemplary embodiment, the method being applied to a network device, such as... Figure 5 As shown, the method includes:

[0126] S501. The network device receives terminal capability information sent by the terminal. The capability information is used to indicate the modulation and coding scheme (MCS) index values ​​supported by the terminal on one or more frequency bands. The MCS index values ​​include some or all of the MCS index values ​​in one or more MCS index tables.

[0127] The capability information can be carried via PUSCH or other uplink signals. In some possible implementations, the capability information may also include other information to indicate other capabilities of the terminal, such as the terminal's current load, its own processing capabilities, and the MCS index table it supports, etc., which are not specifically limited in this disclosure. In addition, the MCS index value used to indicate the terminal's support on one or more frequency bands can be the aforementioned capability information, or any other information, such as UCI, etc., which are not limited in name in this disclosure.

[0128] It should be noted that the MCS index values ​​supported by the terminal can refer to the MCS index values ​​that enable the terminal to obtain the expected gain, or the MCS index values ​​whose gain meets preset conditions. For example, some MCS index values ​​not included in the capability information can be MCS index values ​​that the terminal does not support.

[0129] In addition, an MCS index value can also be described as an MCS index or an MCS value, and an MCS index table can also be described as an MCS table or an MCS table, etc. This disclosure does not limit the name.

[0130] In one embodiment, the MCS index table supported by the terminal can specifically refer to the MCS index table supported by the terminal on one or more frequency bands corresponding to the capability information. Optionally, if the terminal supports a certain MCS index table, it means that the terminal supports the modulation scheme corresponding to that index table, and vice versa.

[0131] In one example, the MCS index value indicated by the capability information includes some or all of the MCS index values ​​in the MCS index table supported by the terminal.

[0132] For example, after a terminal determines that it supports a certain MCS index table in a certain frequency band, it can determine the index value with better gain in the supported MCS index table based on its own capabilities or the quality of the wireless link, and indicate these index values ​​to the network device through capability information.

[0133] As another example, if the capability information includes MCS index values ​​corresponding to MCS index tables that the terminal does not support, the network device can discard or ignore these index values ​​after receiving the capability information. For instance, if the network device determines that the terminal does not support the 256QAM index table based on information previously reported by the terminal device, the network device can discard or ignore these index values ​​even if it receives the index values ​​corresponding to 256QAM.

[0134] In one embodiment, the MCS index value supported by the terminal can be the MCS index value supported by the terminal in each frequency band. Alternatively, it can be the MCS index value supported by the terminal in a certain frequency band. In one embodiment, the terminal can also indicate the MCS index value supported by the terminal in each frequency band by sending capability information multiple times. In some embodiments, the MCS index value can be represented as I. MCS The index value can range from 0 to 31. In the same index table, a higher index value means more useful bits can be transmitted in a single symbol, indicating higher signal quality. 29-31 can be reserved indexes. In some embodiments, which index values ​​a terminal specifically supports can be determined based on its own capabilities, network device capabilities, and / or the quality of the wireless link. For example, if the terminal does not support MCS index 26 in the 256QAM index table, then the MCS index values ​​indicated by the capability information may not include MCS index 26.

[0135] In one example, the terminal supports one or more of the following MCS index tables: 256QAM index table, 64QAM index table, and low spectral efficiency 64QAM index table.

[0136] In some embodiments, the specific index tables supported by the terminal can be determined based on its own capabilities, network device capabilities, and / or the quality of the wireless link. Furthermore, in addition to the index tables mentioned above, the MCS index tables supported by the terminal may also include 2048QAM index tables if other index tables are defined or if the terminal and network devices are further improved with technological advancements, such as supporting 2048QAM modulation. Correspondingly, the MCS index values ​​indicated by the capability information may further include index values ​​from the 2048QAM index table.

[0137] In one example, capability information is also used to indicate the MCS index table supported by the terminal;

[0138] Alternatively, in another example, before receiving the terminal's capability information sent by the receiving terminal, the method further includes:

[0139] The terminal receives the MCS index table supported by the terminal. For details regarding the steps of receiving the MCS index table sent by the terminal, please refer to [link to relevant documentation]. Figure 7 The detailed description of step S701 shown is not repeated here.

[0140] For example, the MCS index table supported by the terminal can be reported to the network device via other signaling or information elements, or it can be reported to the network device through this capability information. That is, if the terminal determines that it supports a certain MCS index table, it can send information indicating the MCS index table it supports in advance before sending the capability information, or it can also carry information indicating the MCS index table it supports through the capability information.

[0141] For example, capability information can also be used to indicate the MCS index tables supported by the terminal and the corresponding MCS index values ​​for those tables. The information element indicating the MCS index tables supported by the terminal and the information element indicating the MCS index values ​​supported by the terminal can be different.

[0142] For example, in related technologies, PUSCH-256QAM is an existing information element. A terminal can use this existing information element, PUSCH-256QAM, to report its support for UL 256QAM. That is, the terminal can inform the network device that it supports the 256QAM index table by reporting this PUSCH-256QAM information element. Upon receiving this PUSCH-256QAM information element, the network device can determine whether the terminal supports the 256QAM index table. As another example, the terminal can also pre-report the ul-64QAM-MCS-TableAlt information element, which can be used to indicate whether the terminal supports the low spectral efficiency 64QAM index table. Alternatively, the terminal can pre-report PUSCH-256QAM to indicate its support for UL 256QAM.

[0143] In an optional embodiment, the PUSCH-256QAM information element can be carried by the capability information. The capability information can indicate that the terminal supports the UL 256QAM modulation method, i.e., the 256QAM index table, and supports the MCS index 0-15, 0-27, or 20-27 in the 256QAM index table. This disclosure does not limit the specific value of the MCS index supported by the terminal indicated by the capability information, and the terminal can set it according to the actual situation.

[0144] In one embodiment, the MCS index value indicated by the capability information may include index values ​​from the 256QAM index table. For example, if the MCS index value indicated by the capability information includes index values ​​from the 256QAM index table, i.e., the terminal supports index values ​​from the 256QAM index table in the corresponding frequency band, and the terminal has previously reported that it supports the 256QAM index table, the network device can determine that the terminal can support these index values. If the terminal does not report its support for the 256QAM index table, or if the terminal reports that it does not support the 256QAM index table, the network device can discard or ignore these MCS index values. In another embodiment, if the terminal also supports 64QAM or low-spectrum-efficiency 64QAM modulation schemes, i.e., the terminal supports the 64QAM index table or the low-spectrum-efficiency 64QAM index table, the MCS index value reported by the terminal may also include some or all of the MCS index values ​​from the 64QAM index table or the low-spectrum-efficiency 64QAM index table.

[0145] In one example, the capability information includes one or more capability information elements, each capability information element corresponds to a first MCS index table, and each capability information element includes the MCS index value supported by the terminal in the corresponding first MCS index table.

[0146] For example, the capability information element can be a newly defined information element (IE) compared to related technologies. The capability information may include multiple capability information elements, and one capability information element may correspond to a modulation scheme, i.e., an MCS index table. For example, one capability information element may correspond to a 256QAM index table, and another capability information element may correspond to a 64QAM index table.

[0147] In one embodiment, the first MCS index table is an MCS index table supported by the terminal.

[0148] In other words, the terminal supports the MCS index table corresponding to each capability information element reported by the terminal.

[0149] For example, if the terminal supports 256QAM index table and 64QAM index table, when the capability information includes capability information elements corresponding to 64QAM, the capability information elements can be used to indicate the index value in the 64QAM index table supported by the terminal. When the capability information includes capability information elements corresponding to 256QAM, the capability information elements can be used to indicate the index value in the 256QAM index table supported by the terminal.

[0150] In one embodiment, the MCS index value indicated by the capability information element may include all or part of the index values ​​in the index table corresponding to the capability information element. For example, if the terminal supports all index values ​​in the 256QAM index table, the terminal can send the capability information element corresponding to the 256QAM index table, and the index value indicated by the capability information element may include all index values ​​in the 256QAM index table. Alternatively, if the terminal supports some index values ​​in the 256QAM index table, the terminal can send the capability information element corresponding to 256QAM, and the index value indicated by the capability information element may include some of the index values ​​in the 256QAM index table that the terminal supports.

[0151] In another embodiment, the first index table may not be an MCS index table supported by the terminal. For example, if the capability information includes capability information elements corresponding to an MCS index table not supported by the terminal, the network device may discard or ignore such capability information elements after receiving them. For instance, if the network device determines that the terminal does not support the 256QAM index table based on information previously reported by the terminal device, the network device may discard or ignore the capability information elements corresponding to 256QAM even if it receives them.

[0152] In one example, when the capability information does not include the capability information element corresponding to the second MCS index table, the capability information is used to indicate that the terminal supports all MCS index values ​​in the second MCS index table; the second index table is the MCS index table supported by the terminal.

[0153] For example, if a terminal supports all index values ​​in the 256QAM index table, the terminal may not need to send the corresponding 256QAM capability information element. For instance, if a terminal lacks the capability to send the capability information element corresponding to the 256QAM index table or has not configured the relevant capability, but the terminal determines that it supports the 256QAM modulation scheme or all index values ​​in the 256QAM index table, it can send capability information that does not include that capability information element, allowing the network device to still configure the index values ​​in the 256QAM index table for it.

[0154] Optionally, if the terminal supports all index values ​​corresponding to a certain index table, the terminal may send the capability information element corresponding to the index table or may not send the capability information element corresponding to the index table. Those skilled in the art can set this according to their actual needs, or the terminal can determine it according to its own capabilities. This disclosure does not limit this.

[0155] In one instance, the capability information element can be defined as follows:

[0156]

[0157] In one embodiment, the capability information element can be named MinMaxMCS-Config-UL-256QAM-r18. The SEQUENCE parameter corresponding to this information element can be used to indicate the frequency band corresponding to the capability information element. The parameter corresponding to MinMCS-PUSCH-r18 is the minimum index value, and the parameter corresponding to MaxMCS-PUSCH-r18 is the maximum index value. The minimum index value can be any integer from 0 to 27, and the maximum index value can be any integer from 0 to 31. For example, after receiving this capability information element, the network device can determine the index value in the 256QAM index table supported by the terminal based on the maximum and minimum index values.

[0158] This capability information element can only correspond to the 256QAM index table. In one implementation, if the terminal supports 256QAM modulation, 64QAM modulation, and low spectral efficiency 64QAM, it can be assumed that the terminal supports all index values ​​in the 64QAM index table and all index values ​​in the low spectral efficiency 64QAM index table. The terminal can then indicate which specific index values ​​in the 256QAM index table it supports by reporting this capability information element, or it can indicate that the terminal supports all index values ​​in the 256QAM index table by not reporting this capability information element.

[0159] In this example, if the terminal supports UL 256QAM modulation, it can further indicate the MCS index value in the 256QAM index table supported by the terminal by sending the capability information element while reporting the PUSCH-256QAM.

[0160] In another example, the capability information element can be defined as follows:

[0161]

[0162]

[0163] In some embodiments, the capability information element can be named MinMaxMCS-Config-r18. The SEQUENCE parameter corresponding to this information element can be used to indicate the frequency band corresponding to the capability information element, and the parameter corresponding to MCS-Table-r18 can be used to indicate the index table corresponding to the capability information element. This signaling is an enumeration signaling, and can only report one modulation scheme at a time. For example, when MCS-Table-r18 = qam64, this indicates that the capability information element corresponds to 64QAM; when MCS-Table-r18 = qam256, this indicates that the capability information element corresponds to 256QAM; and when MCS-Table-r18 = qam64LowSE, this capability information element corresponds to low spectral efficiency 64QAM. Furthermore, the parameter corresponding to MinMCS-PUSCH-r18 is the minimum index value, and the parameter corresponding to MaxMCS-PUSCH-r18 is the maximum index value. The minimum index value ranges from 0 to 27, and the maximum index value ranges from 0 to 31. For example, after receiving the capability information element, the network device can determine the index value in the 256QAM index table supported by the terminal based on the maximum and minimum index values.

[0164] In some optional embodiments, since the terminal is more likely to experience signal modulation failure to achieve the expected gain for high MCS indices, the capability information can be specifically used to indicate the high MCS indices supported by the terminal. Here, a high MCS index can refer to an MCS index with an index value higher than a preset threshold. For example, with a preset threshold of 20, if the terminal supports 256QAM modulation, it can be assumed that the terminal can support MCS index values ​​0-19 in the 256QAM index table, and the capability information only needs to indicate which index values ​​from 20-27 in the 256QAM index table the terminal supports. Furthermore, in one possible implementation, the minimum index value in the capability information element can be defaulted to 0, and the maximum index value can range from a preset threshold to 31 or from a preset threshold to 27.

[0165] Furthermore, a terminal can transmit capability information multiple times for the same frequency band. Each transmission of capability information can include a different index table corresponding to the capability information unit, indicating the supported index values ​​of the terminal in multiple index tables. The network device can configure the MCS configuration information only after confirming that it has received capability information corresponding to all index tables supported by the terminal in the corresponding frequency band.

[0166] Furthermore, if the terminal supports 64QAM, 256QAM, and low-spectrum-efficiency 64QAM, and none of the capability information sent by the terminal for the same frequency band includes the capability information element corresponding to 64QAM, then the terminal supports all index values ​​corresponding to the 64QAM index table. If none of the capability information sent by the terminal includes the capability information element corresponding to low-spectrum-efficiency 64QAM, then the terminal supports all index values ​​corresponding to the low-spectrum-efficiency 64QAM index table.

[0167] In one example, the terminal supports frequency range 2, namely FR2.

[0168] For example, the terminal could be an F2 terminal, and an FR2 terminal could be any terminal supporting millimeter-wave frequency bands between 24.25 GHz and 71 GHz. Referring to relevant technologies, in FR2, when the terminal supports UL 256QAM, link simulation revealed that for high MCS indices, 256QAM cannot achieve the expected gain compared to UL 64QAM. Therefore, by sending capability information indicating the MCS index supported by the terminal, the terminal can effectively ensure that the FR2 terminal achieves the expected gain with 256QAM.

[0169] In one example, after performing step S501, the base station may also perform the following steps: send MCS configuration information to the terminal, the MCS configuration information being used to configure the MCS index values ​​supported by the terminal on one or more frequency bands.

[0170] For a detailed description of this step, please refer to [link / reference]. Figure 6 The detailed description of step S602 shown is not repeated here.

[0171] In this embodiment of the disclosure, the network device receives capability information indicating the MCS index values ​​supported by the terminal. The MCS index values ​​indicated by the capability information may only include the index values ​​supported by the terminal. This allows for a more accurate understanding of the terminal's capabilities, enabling the device to configure the terminal and preventing the terminal from failing to obtain the expected gain for some index values ​​corresponding to its supported modulation schemes, thus ensuring the reliability of transmission.

[0172] Figure 6 This is a flowchart illustrating a capability reporting method according to an exemplary embodiment, the method being applied to a network device, such as... Figure 6 As shown, the method includes:

[0173] S601. The network device receives terminal capability information sent by the terminal. The capability information is used to indicate the modulation and coding scheme (MCS) index values ​​supported by the terminal on one or more frequency bands. The MCS index values ​​include some or all of the MCS index values ​​in one or more MCS index tables.

[0174] For details regarding step S601, please refer to [link / reference]. Figure 5 The detailed description of step S501 shown will not be repeated here.

[0175] S602. The network device sends MCS configuration information to the terminal. The MCS configuration information is used to configure the MCS index values ​​supported by the terminal on one or more frequency bands.

[0176] The information used to configure the MCS index values ​​supported by the terminal on one or more frequency bands can be the aforementioned MCS configuration information, MCS index indication information, or DCI. This disclosure does not limit the name.

[0177] For example, after receiving the MCS configuration information, the terminal can modulate and transmit signals on the corresponding frequency band according to the MCS index value indicated by the MCS configuration information, ensuring that the MCS index value configured in the MCS configuration information is an MCS index value supported by the terminal.

[0178] In one example, the network device may be MCS configuration information determined according to the MCS index value indicated by the capability information, such that the MCS index value corresponding to the MCS configuration information is within the range of MCS index values ​​reported by the terminal. For example, the capability information indicates that the terminal supports MCS index values ​​0-15 in the 256QAM index table. This MCS configuration information may instruct the terminal to use MCS index values ​​0-15, 0-10, or 10-15 in the 256QAM index table for signal modulation.

[0179] In one embodiment, the MCS configuration information can be used to instruct the terminal to select the modulation method of the signal, specifically to instruct the MCS index table and the MCS index value.

[0180] For example, the MCS configuration information may be carried by DCI and / or RRC signaling.

[0181] For example, the MCS index table can be indicated by the PDSCH (Physical Downlink Shared Channel)-Config and SPS (Semi-Persistent Scheduling)-Config parameters in the RRC signaling, thereby enabling the terminal to perform modulation based on the MCS index table indicated by the MCS configuration information.

[0182] For example, the MCS index value used by the terminal can be dynamically configured via DCI. For instance, if the network device determines a change in the quality of the wireless link with the terminal, it can reconfigure the MCS configuration information based on the terminal's capability information and send it to the terminal via DCI. This allows the terminal to perform signal modulation on the corresponding frequency band based on the dynamically indicated MCS index value via DCI.

[0183] Optionally, the MCS index value configured in the MCS configuration information can be determined based on the MCS index values ​​supported by the terminal as indicated by the capability information, so that the MCS index value corresponding to the MCS configuration information is within the range of MCS index values ​​reported by the terminal. For example, if the capability information indicates that the terminal supports MCS index values ​​0-15 in the 256QAM index table, the MCS configuration information can instruct the terminal to use MCS index values ​​0-15, 0-10, or 10-15 in the 256QAM index table for signal modulation.

[0184] In some other possible implementations, the MCS configuration information may specifically be configured by the core network equipment and sent to the base station, and then further sent to the terminal by the base station.

[0185] In this embodiment of the disclosure, the terminal can more accurately report its capabilities by sending capability information indicating the MCS index values ​​it supports and receiving MCS configuration information configured by the network device based on the capability information. This enables the network device to configure the MCS based on the terminal's capabilities, avoiding the terminal failing to obtain the expected gain for some index values ​​corresponding to its supported modulation methods, and ensuring the reliability of transmission.

[0186] In this embodiment of the disclosure, the network device receives capability information indicating the MCS index values ​​supported by the terminal, and configures the MCS configuration information according to the capability information. The network device can more accurately know the terminal's capabilities and enable MCS configuration based on the terminal's capabilities. This avoids the terminal not obtaining the expected gain for some index values ​​corresponding to the modulation scheme it supports, and ensures the reliability of transmission.

[0187] Where there is no contradiction, the embodiments disclosed herein can be combined with other embodiments or implementation methods and their various optional solutions involved in capability reporting methods, which will not be elaborated here.

[0188] Figure 7 This is a flowchart illustrating a capability reporting method according to an exemplary embodiment, the method being applied to a network device, such as... Figure 7 As shown, the method includes:

[0189] S701, The network device receives the MCS index table supported by the terminal sent by the terminal.

[0190] In one embodiment, the terminal may further send an MCS index table that the terminal supports on one or more frequency bands.

[0191] For example, the MCS index tables supported by the terminal can be reported to the network device via other signaling or information elements, such as UCI. Thus, if the terminal determines that it supports a certain MCS index table, it can pre-send information indicating the supported MCS index tables before sending capability information, allowing the network device to configure the terminal's modulation scheme based on the supported index tables.

[0192] S702. The network device receives terminal capability information sent by the terminal. The capability information is used to indicate the MCS index values ​​supported by the terminal on one or more frequency bands. The MCS index values ​​include some or all of the MCS index values ​​in one or more MCS index tables.

[0193] For details regarding step S702, please refer to [link / reference]. Figure 5 The detailed description of step S501 shown will not be repeated here.

[0194] In this embodiment of the disclosure, the network device obtains the MCS index table supported by the terminal by receiving the index table information sent by the terminal in advance. Then, by receiving the capability information, the network device can more reliably determine the MCS index values ​​supported by the terminal on one or more frequency bands indicated by the capability information. This allows the network device to obtain the terminal's capabilities more accurately and enables the network device to configure the MCS based on the terminal's capabilities. This avoids the terminal not obtaining the expected gain for some index values ​​corresponding to its supported modulation methods, thus ensuring the reliability of transmission.

[0195] Where there is no contradiction, the embodiments disclosed herein can be combined with other embodiments or implementation methods and their various optional solutions involved in capability reporting methods, which will not be elaborated here.

[0196] Figure 8 This is an interaction diagram illustrating a capability reporting method according to an exemplary embodiment, such as... Figure 8 As shown, the method includes:

[0197] S801. The terminal sends its capability information to the network device. The capability information is used to indicate the modulation and coding scheme (MCS) index values ​​supported by the terminal on one or more frequency bands. The MCS index values ​​include some or all of the MCS index values ​​in one or more MCS index tables.

[0198] Before step S801, the following step may also be included: the terminal sends the MCS index table supported by the terminal to the network device.

[0199] In addition, after step S801, the method may further include the step of: the network device sending MCS configuration information to the terminal, the MCS configuration information being used to configure the MCS index values ​​supported by the terminal on one or more frequency bands.

[0200] Furthermore, after receiving the MCS configuration information, the terminal can configure the MCS index values ​​on one or more frequency bands according to the MCS configuration information, so that the signal gain on these frequency bands can meet the expectations.

[0201] The specific details of each step involved in the above-described embodiments have been described in detail in the embodiments relating to that step, and will not be elaborated upon here.

[0202] In this embodiment of the disclosure, the terminal sends capability information indicating the MCS index values ​​supported by the terminal. The MCS index values ​​indicated by the capability information may only include the index values ​​supported by the terminal, which can more accurately report the terminal capabilities and avoid the terminal not obtaining the expected gain for some index values ​​corresponding to its supported modulation methods, thus ensuring the reliability of transmission.

[0203] Where there is no contradiction, the embodiments disclosed herein can be combined with other embodiments or implementation methods and their various optional solutions involved in capability reporting methods, which will not be elaborated here.
