Description

Technical Field

[0001] This application relates to the field of wireless communication, and in particular, to a multi-modal analog access method, medium, program product, and terminal based on a 5G NR terminal. Background Art

[0002] According to the technical requirements of the 3GPP protocol, 5G NR terminals consume a relatively large amount of power when accessing the 5G NR network. However, RedCap terminals introduced in 3GPP Release 17 and eRedCap terminals introduced in 3GPP Release 18 consume less power when accessing 5G NR cells that support RedCap terminals and eRedCap terminals in the 5G NR network that supports them. Therefore, if a 5G NR terminal acts as a RedCap terminal or an eRedCap terminal, that is, reports the terminal capabilities that support RedCap or eRedCap to access a 5G NR cell that supports the above RedCap terminal or eRedCap terminal, and acts as a 5G NR terminal when there is a high data rate service requirement, that is, reports the terminal capabilities that support 5G NR terminals to access the 5G NR network, it can greatly reduce its own standby power consumption; another consideration is that a RedCap terminal acts as an eRedCap terminal, that is, reports the terminal capabilities that support eRedCap to access a 5G NR cell that supports eRedCap terminals, which can also achieve a certain amount of power savings. This feature is particularly meaningful in some scenarios that require long-term mobile standby but occasionally require high data rates that can only be achieved by 5G NR or RedCap terminals.

Compared with RedCap, eRedCap has adjusted network capabilities, and the peak rate of both the uplink and downlink is limited to 10 Mbps, and it is suitable for application scenarios served by LTE Cat 1 and LTE Cat 1bis.

[0026] <3>5G NR Terminal: A terminal device that supports 5G NR (New Radio) technology, with communication capabilities of high bandwidth, low latency, and high reliability, and can support the three major application scenarios of 5G: enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), and massive machine-type communication (mMTC). 5G NR terminals usually support higher frequency bands, more complex modulation methods, and multi-antenna technology (MIMO).

[0027] <4>Wireless Access Capability: The technical ability of a terminal device to access the network wirelessly, including the supported frequency band range, bandwidth of various channels, modulation and demodulation methods, antenna configuration, MIMO capability, maximum transmission power, field definitions supported by data and signaling packets at each layer, etc. The wireless access capability determines the compatibility between the terminal and the network, communication performance, and supported service types. The wireless access capability in the embodiments of this document specifically refers to the terminal (UE) capability parameters defined in 3GPP specifications TS 38.306, TS 36.306, and TS 25.306.

[0028] <5>Network Type Indicator Bit: A specific information bit used to identify the network type, usually included in network configuration messages or system broadcasts. It helps the terminal identify the current accessed network type (such as 5G NR, LTE, eHRPD, etc.), so that the terminal can adjust the working mode, parameter configuration, or handover strategy according to the network type.

[0029] <6>5G NR cell: A basic component in the 5G (5th Generation Mobile Communication Technology) network that provides wireless coverage based on the NR (New Radio) air interface technology defined by 3GPP.

[0030] <7>5G NR cell supporting RedCap terminals: A 5G NR cell that complies with the standards of 3GPP Release 17 and subsequent versions, and the system information block SIB1 sent by this cell contains the cell parameter intraFreqReselectionRedCap, and the value of this cell parameter is "allowed".

[0031] <8>5G NR cell not supporting RedCap terminals: A 5G NR cell that complies with 3GPP standards, and this cell does not send the system information block SIB1, or the system information block SIB1 sent by this cell does not contain the cell parameter intraFreqReselectionRedCap, or the system information block SIB1 sent by this cell contains the cell parameter intraFreqReselectionRedCap, but the value of this cell parameter is "notAllowed".

[0032] <9>5G NR cell supporting eRedCap terminals: A 5G NR cell that complies with the standards of 3GPP Release 18 and subsequent versions, and the system information block SIB1 sent by this cell contains the cell parameter intraFreqReselection-eRedCap, and the value of this cell parameter is "allowed".

[0033] <10>5G NR cell not supporting eRedCap terminals: A 5G NR cell that complies with 3GPP standards, and this cell does not send the system information block SIB1, or the system information block SIB1 sent by this cell does not contain the cell parameter intraFreqReselection-eRedCap, or the system information block SIB1 sent by this cell contains the cell parameter intraFreqReselection-eRedCap, but the value of this cell parameter is "notAllowed".

[0034] <11>LTE cell: An LTE (Long-Term Evolution) cell is the basic coverage unit in an LTE network, consisting of one or more base stations (eNodeB), responsible for providing wireless access services. The cell realizes wireless access and data transmission to users by allocating different frequency band and time slot resources.

[0035] <12>Msg1 Phase: The first phase of the 4-step random access (RA) process. The terminal sends a preamble to the network to initiate an access request, synchronize timing, and obtain uplink resource allocation. The Msg1 phase is the initial step for the terminal to establish a connection with the network. The network determines the presence of the terminal by detecting the preamble and allocates subsequent resources.

[0036] <13>Msg3 Phase: The third phase of the 4-step random access (RA) process. The terminal makes its first transmission according to network scheduling during the random access process. The Msg3 message can carry MAC layer and RRC layer signaling or data. This phase is a key step for information interaction between the terminal and the network.

[0037] <15>MsgA Phase: The first phase of the 2-step random access (RA) process, which includes a preamble and a payload on a pre-configured PUSCH. The content of the payload is basically the same as that of Msg3 in the 4-step random access.

[0038] <16>CCCH: Common Control Channel, which is a downlink channel for all users and is used to broadcast system messages, paging messages, or random access responses and other common information. The CCCH is not targeted at specific users but is for all terminals to receive and parse.

[0039] <17>LCID: Logical Channel ID, which is used to distinguish data on different logical channels at the MAC layer. Each LCID corresponds to a logical channel type (such as broadcast channel, paging channel, dedicated control channel, etc.), ensuring that data can be correctly mapped to the corresponding logical channel during transmission.

[0040] <18>User Terminal Capability Information: Refers to the hardware and software function information supported by the terminal device, including the supported frequency band range, bandwidth size, modulation method, MIMO capability, maximum transmit power, etc. This information is reported by the terminal to the network for network configuration, resource allocation, and optimization to ensure the compatibility and performance between the terminal and the network.

[0041] The technical solutions of the embodiments of this application can be applied to various communication systems and scenarios, such as: the 5th Generation (5G) communication system, New Radio Access Technology (NR), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), etc. Among them, it is particularly suitable for scenarios that can improve the flexibility of terminals such as RedCap terminals, eRedCap terminals, and 5G NR terminals to access the network, the utilization efficiency of network resources, and reduce the average standby power consumption of terminals, including but not limited to Industrial Internet of Things (IIoT), Smart City, Smart Grid, Wearable Devices, Intelligent Transportation Systems (ITS), and Low Power Wide Area Network (LPWAN) and other fields. This application optimizes the network access control mechanism, allowing 5G NR terminals to access 5G NR cells that support RedCap in the identity of RedCap terminals, or access 5G NR cells that support eRedCap in the identity of eRedCap terminals; and allowing RedCap terminals to access 5G NR cells that support eRedCap in the identity of eRedCap terminals, thereby breaking through the limitations of the prior art, improving the flexibility of terminal access and the overall utilization efficiency of network resources while reducing the average standby power consumption of terminals.

[0042] To facilitate the understanding of the embodiments of this application, first, in combination with Figure 1 it is described in detail. Figure 1 FIG. shows a schematic flowchart of a multi-modal analog access method based on a 5G NR terminal in the embodiments of the present invention. The multi-modal analog access method based on a 5G NR terminal in this embodiment is applied to a terminal, and the terminal has a first terminal capability mode and a second terminal capability mode. The method includes:

[0043] Step S11: Obtain the user's network preference, current service information, and the hardware configuration information of the terminal: Based on the user's network preference, current service information, and the hardware configuration information of the terminal, perform the following operations.

[0044] In an embodiment of the present application, the user network preference refers to the configuration of the terminal access mode according to the network rules set by the user based on their own needs and usage habits; the current service information includes the network requirements of the applications running on the terminal, such as high bandwidth for video calls and low latency for games; the hardware configuration of the terminal refers to the network capabilities of the device hardware, such as whether it supports a specific Category of 5G NR, RedCap, eRedCap, LTE, the number of antennas, the battery power, etc.

[0045] In an embodiment of the present application, the user network preference parameters are stored in the non-volatile memory of the terminal; and / or the user network preference parameters are stored in the USIM card.

[0046] In this embodiment, the parameters are saved in the non-volatile memory of the terminal to ensure that these settings can still be retained and used even after the device is powered off or restarted. In addition, the parameters can also be optionally stored in the USIM card, which can achieve configuration sharing between devices, enabling the user to maintain consistent network preference settings when using different devices, thereby improving the user's convenience and experience.

[0047] In an embodiment of the present application, the user network preference parameters are configured by the terminal in any of the following ways: configuration commands transmitted through the hardware interface of the terminal; configuration options through the operation interface of the terminal.

[0048] In this embodiment, the user sends specific configuration commands through the hardware interface of the terminal, for example, USB or Bluetooth, to adjust the parameters. Alternatively, the terminal provides intuitive menu options through the operation interface, and the user can change their network preferences by simple clicks and selections to improve the convenience of operation.

[0049] Step S12: Perform software and hardware configuration operations to enable the terminal to be in the first terminal capability mode, and report the terminal capability parameters corresponding to the first terminal capability mode to the currently accessed network through the first message mechanism.

[0050] In an embodiment of the present application, such as Figure 2As shown, when the terminal is in the first terminal capability mode, the process of reporting terminal capability parameters corresponding to the first terminal capability mode to the current access network through the first message mechanism includes: when the current resident cell is a 5G NR cell supporting RedCap terminals or eRedCap terminals, during the random access process, indicating to the current access cell that the type of the currently accessed terminal is a RedCap terminal or an eRedCap terminal through the preamble signal in the MSG1 / MSGA message; when the current resident cell is a 5G NR cell supporting RedCap terminals or eRedCap terminals, during the random access process, indicating to the current access cell that the type of the currently accessed terminal is a RedCap terminal or an eRedCap terminal through the CCCH logical signal identifier in the MSG3 / MSGA message; when the first terminal capability mode is the RedCap terminal capability mode and the resident cell is a 5G NR cell supporting RedCap terminals or the first terminal capability mode is the eRedCap terminal capability mode and the resident cell is a 5G NR cell supporting eRedCap terminals or the resident cell is an LTE cell, triggering the current access network to initiate the registration process of terminal capability transfer through the NAS layer, and reporting the terminal capability information as the terminal capability information corresponding to the first terminal capability mode.

[0051] In this embodiment, the RedCap (Reduced Capability) terminal is a technical standard protocol introduced by 3GPP in the Release 17 phase, aiming to provide a lightweight 5G solution for 5G application scenarios with low requirements for rate and latency. The RedCap terminal reduces the terminal complexity and cost by trimming some functions. The RedCap terminal indicates that it is a RedCap terminal by reporting the main capability supportOfRedCap-r17 cell to the base station. eRedCap (Enhanced RedCap) is a further evolved version of the RedCap technology and is a technical standard protocol introduced by 3GPP in the Release 18 phase. Compared with RedCap, eRedCap has adjusted network capabilities, and the peak rates of the uplink and downlink are limited to 10 Mbps, which is suitable for application scenarios served by LTE Cat1 and LTE Cat1bis. The eRedCap terminal indicates that it is an eRedCap terminal by reporting the main capability supportOfERedCap-r18 cell to the base station.

[0052] In this embodiment, in the 5G NR network, the access process of the RedCap terminal or eRedCap terminal follows the random access procedure specified in 3GPP protocol 38.321. Specifically, in the MSG1 and MSGA phases, the MAC layer of the RedCap terminal or eRedCap terminal selects a preamble from the dedicated random access resource set configured by the network and sends the preamble using the time-frequency resources specified in the resource set to ensure that the terminal initiates an access request in a manner that meets the access capability requirements of RedCap or eRedCap. In the MSG3 and MSGA phases, when the terminal sends a message through the CCCH (Common Control Channel) or CCCH1, it carries the logical channel LCID (Logical Channel Identifier) dedicated to the RedCap terminal or eRedCap terminal, so that the network to be accessed can identify the access request of the RedCap terminal or eRedCap terminal and allocate appropriate resources for it, thus achieving efficient access.

[0053] Furthermore, in the 5G NR network, the terminal selects a suitable access resource set, initiates the random access procedure through the logical channel identifier and carries standard uplink information, and after completing the random access, reports the radio access capability corresponding to the current terminal capability mode to the network in the subsequent AS access layer uplink signaling.

[0054] In the LTE network, the radio access capability corresponding to the current terminal capability mode is reported to the network in the AS access layer uplink signaling.

[0055] In this embodiment, software and hardware configuration operations are performed to enable the terminal to be in the first terminal capability mode. The terminal in the first terminal capability mode can be in the RedCap terminal capability mode or the eRedCap terminal capability mode. Among them, when the first terminal capability mode is the RedCap terminal capability mode, the software and hardware configuration operations are performed based on 3GPP technical specification TS38.331 Release 17 and above versions; when the first terminal capability mode is the eRedCap terminal capability mode, the software and hardware configuration operations are performed based on 3GPP technical specification TS 38.331 Release 18 and above versions. The above software and hardware configuration operations include terminal software configuration and terminal hardware configuration. Specifically, in terms of software, the protocol stack of the terminal is updated to enable the terminal to support the 3GPP protocol and its Release version corresponding to the set first terminal capability mode; in terms of hardware, the terminal adjusts its own radio frequency module to enable it to support the frequency band, bandwidth, corresponding maximum data rate required for the RedCap terminal capability mode or the eRedCap terminal capability mode, and the number of RBs (Resource Blocks) that the PDSCH and PUSCH set in the eRedCap terminal capability mode can handle.

[0056] In this embodiment, when the type of the currently accessed cell is a 5G NR cell that supports RedCap terminals, the terminal in the RedCap terminal capability mode reports its radio access capability in the RedCap terminal capability mode in the terminal capability information message (UECapability Information message defined in 3GPP technical specification TS 38.331). The terminal capability information message is an important signaling for reporting the functions and parameters supported by it to the 5G NR cell network that supports RedCap terminals to be accessed, so that the network can understand the access capability of the terminal. The user terminal capability information includes information elements (IEs) for describing the status of the terminal as a RedCap terminal.

[0057] Exemplarily, the information element includes the redCapParameters-r17 field. In this field, the terminal sets the supportOfRedCap-r17 field in the protocol to true to indicate that the current terminal is a RedCap terminal. In addition, the reported RedCap capability parameters of the terminal also include the radio access capability parameters of 5G NR (including RedCap and eRedCap related sub-functions), as well as the radio access capability parameters of other communication systems such as LTE and WCDMA supported by the terminal, to assist the access network in determining whether the current terminal meets the access requirements of the 5G NR cell that supports RedCap terminals.

[0058] In this embodiment, when the type of the currently accessed cell is a 5G NR cell supporting eRedCap, a terminal in the eRedCap terminal capability mode reports its radio access capability in the eRedCap terminal capability mode in the terminal capability information message (UECapability Information message defined in 3GPP technical specification TS 38.331). The terminal capability information message is the core signaling for reporting the functions and parameters supported by the terminal to the 5G NR cell network of the eRedCap terminal to be accessed, so that the network can understand the access capability of the terminal. The user terminal capability information includes information elements (IEs) for describing the status of the terminal as an eRedCap terminal.

[0059] Exemplarily, the information element includes the eRedCapParameters-r18 field. In this field, the terminal sets the supportOfERedCap-r18 field in the protocol to true to indicate that the current terminal is an eRedCap terminal. In addition, the reported eRedCap capability parameters of the terminal also include the radio access capability parameters of 5G NR (including RedCap and eRedCap-related sub-functions), as well as the radio access capability parameters of other communication systems supported by the terminal, such as LTE, WCDMA, etc., to assist the access network in determining whether the current terminal meets the access requirements of the 5G NR cell for RedCap terminals.

[0060] In this embodiment, when the type of the currently accessed network is an LTE cell, a terminal in the RedCap terminal capability mode reports its radio access capability in the RedCap terminal capability mode in the terminal capability information (UE Capability Information message defined in 3GPP technical specification TS 36.331). The uplink air interface message of LTE includes a ueCapabilityRAT-Container cell with the corresponding RAT-Type being nr (this cell is described by the UE-NR-Capability structure defined in 3GPP technical specification TS38.331). It includes an information element containing redCapParameters-r17. In this field, the terminal sets the supportOfRedCap-r17 field in the protocol to true; at the same time, it does not contain the "supportOfERedCap-r18" IE to indicate that the terminal is not an eRedCap terminal. At the same time, it reports the radio access capability parameters of 5G NR (including RedCap and eRedCap-related sub-functions) supported by the terminal, as well as the radio access capability parameters of other communication systems supported by the terminal, such as LTE, WCDMA, GSM\GPRS\EDGE, etc.

[0061] In this embodiment, when the type of the currently accessed network is an LTE cell, a terminal in the eRedCap terminal capability mode reports its radio access capability in the eRedCap terminal capability mode in the terminal capability information (UE Capability Information message defined in 3GPP technical specification TS 36.331). The uplink air interface message of LTE includes a ueCapabilityRAT-Container cell with the corresponding RAT-Type being nr (this cell is described by the UE-NR-Capability structure defined in 3GPP technical specification TS 38.331). It includes an information element of eRedCapParameters-r18. In this field, the terminal sets the supportOfERedCap-r18 field in the protocol to true. Meanwhile, it reports the radio access capability parameters of 5G NR (including RedCap and eRedCap-related sub-functions) supported by the terminal, as well as the radio access capability parameters of other communication systems such as LTE, WCDMA, GSM / GPRS / EDGE, etc. supported by this terminal.

[0062] Step S13: Perform software and hardware configuration operations to make the terminal in the second terminal capability mode, and report the terminal capability parameters corresponding to the second terminal capability mode to the currently accessed network through the second message mechanism.

[0063] In an embodiment of this application, as Figure 3 shown, when the terminal is in the second terminal capability mode, the process of reporting the terminal capability parameters corresponding to the second terminal capability mode to the currently accessed network through the second message mechanism includes:

[0064] When the second terminal capability mode is the 5G NR terminal capability mode: when the currently resident cell is a cell supporting 5G NR, during the application of the random access process, the preamble signal in the MSG1 / MSGA message is used to indicate to the currently accessed cell that the type of the currently accessed terminal is a 5G NR terminal; when the currently resident cell is a cell supporting 5G NR, during the application of the random access process, the CCCH logical signal identifier in the MSG3 / MSGA message is used to indicate to the currently accessed cell that the type of the currently accessed terminal is a 5G NR terminal; when the resident cell is a 5G NR cell or an LTE cell, the NAS layer is used to trigger the registration process of the currently accessed network to initiate terminal capability transfer, and report the terminal capability information as the terminal capability information in the 5G NR terminal capability mode.

[0065] When the second terminal capability mode is the RedCap terminal capability mode: When the current resident cell is a 5G NR cell supporting RedCap terminals, during the random access process, the preamble signal in the MSG1 / MSGA message is used to indicate to the currently accessed cell that the terminal type currently accessing is a RedCap terminal; when the current resident cell is a 5G NR cell supporting RedCap terminals, during the random access process, the CCCH logical signal identifier in the MSG3 / MSGA message is used to indicate to the currently accessed cell that the terminal type currently accessing is a terminal; when the resident cell is a 5G NR cell or an LTE cell supporting RedCap terminals, the current access network is triggered through the NAS layer to initiate a registration process for terminal capability transfer, and the terminal capability information reported is the terminal capability information corresponding to the RedCap terminal capability mode.

[0066] In this embodiment, in the 5G NR network, the access process of 5G NR terminals or RedCap terminals follows the random access procedure specified in 3GPP protocol 38.321. Specifically, in the MSG1 stage and the MSGA stage, the MAC layer of the 5G NR terminal or RedCap terminal selects a preamble from the dedicated random access resource set configured by the network and uses the time-frequency resources specified in this resource set to send the preamble, so as to ensure that the terminal initiates an access request in a manner that meets the radio access capability requirements of 5G NR terminals or RedCap terminals. In the MSG3 stage and the MSGA stage, when the terminal sends a message through the CCCH (Common Control Channel) or CCCH1, it carries the logical channel LCID (Logical Channel Identifier) dedicated to 5G NR terminals or RedCap terminals, so that the network to be accessed can identify the access request of 5G NR terminals or RedCap terminals and allocate appropriate resources for it, thus achieving efficient access.

[0067] Furthermore, in the 5G NR network, the terminal selects a suitable access resource set, initiates a random access procedure through the logical channel identifier and carries standard uplink information, and after completing the random access, reports the radio access capability corresponding to the current terminal capability mode to the network in the subsequent AS access layer uplink signaling.

[0068] In the LTE network, the radio access capability corresponding to the current terminal capability mode is reported to the network in the AS access layer uplink signaling.

[0069] In this embodiment, software and hardware configuration operations are performed to enable the terminal to be in the second terminal capability mode. The terminal in the second terminal capability mode can be in the 5G NR terminal capability mode or the RedCap terminal capability mode. Among them, when the first terminal capability mode is the 5G NR terminal capability mode, the software and hardware configuration operations are performed based on the 3GPP technical specification TS38.331 Release 15 and above versions; when the second terminal capability mode is the RedCap terminal capability mode, the software and hardware configuration operations are performed based on the 3GPP technical specification TS 38.331 Release 17 and above versions. The above software and hardware configuration operations include terminal software configuration and terminal hardware configuration. Specifically, in terms of software, the protocol stack of the terminal is updated so that the terminal supports the 3GPP protocol and its Release version corresponding to the set second terminal capability mode; in terms of hardware, the terminal adjusts its own radio frequency module so that it can support the frequency bands, bandwidths, and corresponding maximum data rates required for the 5G NR terminal capability mode or the RedCap terminal capability mode.

[0070] In this embodiment, when the type of the currently accessed cell is a 5G NR cell, the terminal in the 5G NR terminal capability mode reports its radio access capability in the 5G NR terminal capability mode in the terminal capability information message (UE Capability Information message defined in the 3GPP technical specification TS 38.331). The terminal capability information message is an important signaling for reporting the functions and parameters supported by it to the 5G NR cell network supporting RedCap terminals to be accessed, so that the network can understand the access capability of the terminal. The user terminal capability information includes information elements (IEs) for describing the status of the terminal as a RedCap terminal.

[0071] Specifically, in the 5G NR terminal capability mode, the user terminal capability information does not contain the "redCapParameters-r17" IE to indicate that the terminal is not a RedCap terminal; at the same time, it also does not contain the "supportOfERedCap-r18" IE to indicate that the terminal is not an eRedCap terminal. In addition, the reported 5G NR capability parameters of the terminal also include the radio access capability parameters of the 5G NR (including RedCap and eRedCap related sub-functions) supported by it, as well as the radio access capability parameters of other communication systems such as LTE and WCDMA supported by the terminal, to assist the access network in determining whether the current terminal meets the access requirements of the 5G NR cell.

[0072] In this embodiment, when the type of the currently accessed cell is a 5G NR cell that supports RedCap terminals, a terminal in the RedCap terminal capability mode reports its radio access capability in the RedCap terminal capability mode in a terminal capability information message (UECapability Information message defined in 3GPP technical specification TS 38.331). The terminal capability information message is an important signaling for reporting the functions and parameters supported by the terminal to the 5G NR cell network that supports RedCap terminals to be accessed, so that the network can understand the access capability of the terminal. The user terminal capability information includes information elements (IEs) for describing the status of the terminal as a RedCap terminal.

[0073] Exemplarily, the information element includes a redCapParameters-r17 field. In this field, the terminal sets the supportOfRedCap-r17 field in the protocol to true to indicate that the current terminal is a RedCap terminal. In addition, the reported RedCap capability parameters of the terminal also include the radio access capability parameters of the supported 5G NR (including RedCap and eRedCap related sub-functions), as well as the radio access capability parameters of other communication systems such as LTE and WCDMA supported by the terminal, to assist the access network in determining whether the current terminal meets the access requirements of the 5G NR cell that supports RedCap terminals.

[0074] In this embodiment, when the type of the currently accessed network is an LTE cell, a terminal in the 5G NR terminal capability mode reports its radio access capability in the RedCap terminal capability mode in the terminal capability information (UE Capability Information message defined in 3GPP technical specification TS 36.331). The uplink air interface message of LTE includes a ueCapabilityRAT-Container cell with a corresponding RAT-Type of nr (this cell is described by the UE-NR-Capability structure defined in 3GPP technical specification TS38.331). In particular, in the 5G NR terminal capability mode, the user terminal capability information does not contain the "RedCapParameters-r17" IE to indicate that the terminal does not support the RedCap function; at the same time, it also does not contain the "supportOfERedCap-r18" IE to indicate that the terminal is not an eRedCap terminal.

[0075] In this embodiment, when the type of the currently accessed network is an LTE cell, a terminal in the RedCap terminal capability mode reports its radio access capability in the RedCap terminal capability mode in the terminal capability information (UE Capability Information message defined in 3GPP technical specification TS 36.331). The uplink air interface message of LTE includes a ueCapabilityRAT-Container cell with the corresponding RAT-Type being nr (this cell is described by the UE-NR-Capability structure defined in 3GPP technical specification TS38.331). It includes an information element of redCapParameters-r17. In this field, the terminal sets the supportOfRedCap-r17 field in the protocol to true; at the same time, it also does not contain the "supportOfERedCap-r18" IE to indicate that the terminal is not an eRedCap terminal. Meanwhile, it reports the radio access capability parameters of 5G NR supported by the terminal (including RedCap and eRedCap related sub-functions), as well as the radio access capability parameters of other communication systems supported by this terminal, such as LTE, WCDMA, GSM / GPRS / EDGE, etc.

[0076] In an embodiment of the present application, the above terminal capability parameters include the radio access capability parameters of 5G NR supported by the terminal (including RedCap and eRedCap related sub-functions), as well as the radio access capability parameters of other communication systems supported by this terminal, such as LTE, WCDMA, GSM / GPRS / EDGE, etc.

[0077] In this embodiment, the communication protocol version is used to determine whether the terminal is compatible with the RedCap or eRedCap function; the frequency band is used to configure the 5G operating frequency range supported by the terminal; the bandwidth is used to configure the communication capability and resource allocation efficiency of the terminal; the modulation method is used to configure the data transmission efficiency and anti-interference performance of the terminal; the antenna configuration includes the number of antennas and MIMO (Multiple Input Multiple Output) technology to adjust the signal reception quality and transmission rate of the terminal; the maximum transmission rate is used to evaluate the data transmission capability of the terminal in the RedCap or eRedCap mode, providing an important basis for network optimization and resource allocation.

[0078] In an embodiment of the present application, the method includes: when the data rate requirement of the data service to be carried by the terminal is not higher than the highest data rate requirement of the first terminal capability mode, perform software and hardware configuration operations to make the terminal be in the first terminal capability mode; otherwise, perform software and hardware configuration operations to make the terminal be in the second terminal capability mode.

[0079] In an embodiment of the present application, when the data rate requirement of the data service that the terminal needs to carry is not higher than the maximum data rate requirement of the first terminal capability mode and meets any of the following conditions, perform software and hardware configuration operations, further configure the following features on the basis of configuring the terminal to the first terminal capability mode, and adjust the corresponding terminal capability parameters reported in the corresponding terminal capability information; when the maximum number of DRBs required for the data service that the terminal needs to carry is no more than 8, configure the maximum number of DRBs of the first terminal capability mode to 8; when the PDCP SN length required for the data service that the terminal needs to carry is 12 bits, configure the first terminal capability mode to only support the PDCP SN length of 12 bits and not support the PDCP SN length of 18 bits; when the RLC SN length required for the data service that the terminal needs to carry is 12 bits, configure the first terminal capability mode to only support the RLC SN length of 12 bits and not support the RLC SN length of 18 bits; when the quality of service required for the data service that the terminal needs to carry can be met under the condition that the carrier bandwidth is 20 MHz and the number of receive antennas is 2Rx / 1Rx receive antennas, configure the number of receive antennas of the first terminal capability mode to 2Rx / 1Rx.

[0080] In this embodiment, when the rate of the data service does not exceed the maximum supported rate of the first terminal capability mode and meets specific conditions, the terminal will automatically perform software and hardware configuration operations. Specifically, on the basis of the first terminal capability mode, the terminal will finely adjust the specific configuration features of the terminal, and correspondingly update and report the terminal capability information. Its ultimate goal is to achieve precise matching and optimization of the terminal performance according to the actual service requirements, so as to improve the overall efficiency of network communication and user experience. This dynamic configuration method reflects the principles of intelligence and self-adaptability pursued by modern communication systems, in order to flexibly meet the differentiated requirements of different service scenarios.

[0081] In this embodiment, the data rate requirement of the data service that the above terminal needs to carry refers to the communication requirements of the internal applications of the terminal. The rate requirement represents the data transmission capability required by the terminal when it executes its functions. Specifically, the data rate of the service data that the terminal needs to carry can be determined by collecting and statistically analyzing the requirements of its internal applications. This process involves evaluating the performance of the terminal in different usage scenarios to ensure that it can meet the requirements of actual applications. In addition, based on historical experience data or the service characteristics of the applications used, the requirements that may occur in a future period can be estimated. Such estimation not only helps to optimize resource allocation, but also provides guidance for the design and upgrade of the terminal, so as to ensure its efficient communication ability in a dynamic environment.

[0082] In this embodiment, when the maximum number of Data Radio Bearers (DRBs) for the data service that the terminal needs to carry is no more than 8, the maximum DRB number of the first terminal capability mode of the terminal is configured to 8. At this time, the first terminal capability mode can support up to 8 data bearers. Configuring the maximum DRB number to 8 can ensure that the terminal can process multiple data streams simultaneously, meet its high data transmission requirements, and thus improve the overall user experience and communication quality.

[0083] In this embodiment, when the length of the Packet Data Convergence Protocol Sequence Number (PDCP SN) required for the data service that the terminal needs to carry is 12 bits, the first terminal capability mode is configured to support only the PDCP SN length of 12 bits and does not support the PDCP SN length of 18 bits. Supporting the 12-bit PDCP SN length enables the terminal to ensure the orderly transmission of data packets. Although it cannot support 18 bits, this design balances the effectiveness of the required service and the bandwidth utilization efficiency.

[0084] In this embodiment, when the length of the Radio Link Control Sequence Number (RLC SN) required for the data service that the terminal needs to carry is 12 bits, the first terminal capability mode is configured to support only the RLC SN length of 12 bits and does not support the RLC SN length of 18 bits. Supporting the 12-bit RLC SN length can ensure the effective management and reliability of the radio link. Although it does not support longer sequence numbers, this configuration can achieve reliable data communication within the device capabilities.

[0085] In this embodiment, when the quality of the data service that the terminal needs to carry can be met under the conditions that the carrier bandwidth is 20 MHz (megahertz) and the number of receive antennas is 2Rx (Two Receive Antennas) or 1Rx (One Receive Antennas), the number of receive antennas of the first terminal capability mode is configured to 2Rx / 1Rx. By configuring 2Rx / 1Rx receive antennas, not only can the signal quality and data processing ability be significantly improved, but also a reliable quality of service can be provided under a 20 MHz bandwidth, ensuring that the terminal can still efficiently and stably carry data services even in a complex communication environment. The service quality includes but is not limited to wireless communication data transmission quality indicators such as Bit Error Rate (BER), Block Error Rate (BLER), and Packet Loss Rate (PLR).

[0086] In the embodiments of the present application, terms such as "first" and "second" are used to distinguish identical or similar items with basically the same functions and roles.
