Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a message processing method and a message processing device.
Background
With the development of communication technology, a 5G (fifth generation mobile communication network) network can achieve a higher transmission rate than a 4G (fourth generation mobile communication technology) network in the context of an eMBB (Enhance Mobile Broadband, enhanced mobile broadband).
In order to achieve higher uplink transmission rate and spectrum efficiency, in the 5G network, the UE (User Equipment) may support a 64QAM (Quadrature Amplitude Modulation ) modulation mode by uplink default, and in addition, in the case of UE capability support, an uplink 256QAM modulation mode may be selected. Since the uplink 256QAM modulation mode requires UE capability support, the base station may configure the uplink 256QAM modulation mode to enable the UE to transmit uplink data through the uplink 256QAM modulation mode if it is determined that the UE has capability to support the uplink 256QAM modulation mode.
However, the base station may acquire UE capability information after RRC (Radio Resource Control ) connection between the UE and the base station is established, where the UE capability information indicates whether the UE supports an uplink 256QAM modulation mode on each frequency band supported by the UE. In addition, in case that the UE initiates RRC connection restoration, if the base station cannot acquire the UE context (including UE capability information), it is necessary to fall back to the RRC connection establishment procedure and acquire the UE capability information after RRC connection establishment is completed.
From this, it can be seen that the current base station obtains the UE capability information at a later time, thereby affecting the transmission efficiency of the uplink data.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Method embodiment one
Referring to fig. 1, a flowchart of a first embodiment of a message processing method of the present invention is shown and applied to a network device, where the method specifically may include:
102, receiving a Radio Resource Control (RRC) uplink message sent by user equipment;
104, sending an RRC downlink message to the user equipment so that the user equipment configures the first uplink modulation mode; the RRC downlink message carries a second field indicating the first uplink modulation mode.
In the embodiment of the present invention, the network device may be a device for communicating with a mobile device, and may specifically include: base stations in 5G networks, BTSs (Base Transceiver Station, base stations) in GSM (Global System of Mobile communication, global system for mobile communications) or CDMA (Code Division Multiple Access ), NB (NodeB, base station) in WCDMA (Wideband Code Division Multiple Access ), enbs or enodebs (Evolutional Node B, evolved base station) or access points in LTE (Long Term Evolution ), or vehicle devices, wearable devices, or network devices in PLMN (Public Land Mobile Network ) networks, etc.
It can be understood that, for convenience of description, in the embodiment of the present invention, the network device is taken as a base station in the 5G network as an example, and application scenarios of other network devices may be referred to each other.
The embodiment of the invention can carry the reference threshold corresponding to the first uplink modulation mode in the system message broadcast by the base station, and the reference threshold can be used for providing the judgment basis for judging whether the RSRP (Reference Signal Receiving Power ) of the cell where the user equipment is currently located is suitable for the first uplink modulation mode or not. For convenience of description, the embodiment of the present invention uses the first uplink modulation mode as an uplink 256QAM modulation mode as an example.
For example, an optional field may be added in the uplink configuration of SIB1 (System Information Block Type, system message block) to store the reference threshold corresponding to the first uplink modulation mode. Suppose that the following optional fields are newly added in the UpLinkConfigCommon structure of SIB 1: the rsrp-Threshold InitialMcsTable256QamUl is used for storing a reference threshold corresponding to an uplink 256QAM modulation mode.
After receiving the system message broadcast by the base station, the ue can determine whether to recommend the base station to configure the uplink 256QAM modulation mode according to the RSRP of the cell in which the ue is currently located and the reference threshold carried in the system broadcast. Specifically, if the ue supports the uplink 256QAM modulation mode in the current frequency band, and the ue detects that the reference signal received power of the current cell exceeds the reference threshold, which indicates that the current environment is suitable for transmitting uplink data using the first uplink modulation mode, an RRC uplink message carrying a first field indicating the first uplink modulation mode may be sent to the base station. The first field is used for indicating that the base station currently recommends to transmit uplink data by using an uplink 256QAM modulation mode.
Under the condition that the base station detects that the received RRC uplink message carries the first field, the base station can determine that the user equipment supports an uplink 256QAM modulation mode, and the environment of the cell where the user equipment is currently located is also suitable for transmitting uplink data by using the uplink 256QAM modulation mode, so that the base station can send the RRC downlink message carrying the second field indicating the first uplink modulation mode to the user equipment so as to inform the user equipment of configuring the first uplink modulation mode.
The RRC uplink message may specifically include: an RRC connection setup request message or an RRC connection restoration request message. The RRC downlink message may specifically include: RRC connection setup message or RRC connection resume message.
In an alternative embodiment of the present invention, the reference threshold may be set according to factors such as a signal-to-noise ratio of a channel and a transmitting power of a base station, for example, if the transmitting power of the base station is higher, a higher reference threshold may be set, if the transmitting power of the base station is lower, a lower reference threshold may be set, etc., it will be understood that embodiments of the present invention are not limited to a specific manner of setting the reference threshold.
The user equipment monitors RSRP (Reference Signal Receiving Power, reference signal received power) of the currently camping cell signal in rrc_idle (RRC IDLE state) or rrc_inactive (RRC connected INACTIVE state) for cell reselection. When the ue prepares to initiate an RRC connection establishment or RRC connection recovery procedure, if the ue supports uplink 256QAM in the current frequency band, the smoothed cell RSRP may be compared with a reference threshold corresponding to the uplink 256QAM modulation mode indicated in SIB1, and if the RSRP exceeds the reference threshold, the ue may recommend that the base station initially configure the uplink 256QAM modulation mode, and specifically, the ue may carry a first field indicating the uplink 256QAM modulation mode, such as a recommendaul 256QAM field, in an RRC uplink message to prompt the base station to initially configure the uplink 256QAM modulation mode.
After receiving an RRC uplink message (e.g., an RRC connection establishment request message or an RRC connection restoration request message) of a user equipment, if it is detected that the RRC uplink message carries a first field (e.g., a recommendaul 256QAM field) indicating an uplink 256QAM modulation mode, it may be determined that the user equipment supports the uplink 256QAM modulation mode, and a cell environment where the user equipment is currently located is suitable for transmitting uplink data using the uplink 256QAM modulation mode, then the base station side may configure the uplink 256QAM modulation mode to parse uplink data of the user equipment using the uplink 256QAM modulation mode, and send, to the user equipment, an RRC downlink message carrying a second field indicating the first uplink 256QAM modulation mode, so as to notify that the user equipment may perform a configuration operation of the uplink 256QAM modulation mode.
The second field may specifically be an mcs-Table field in a PUSCH-Config structure, and if the RRC downlink message sent by the base station to the user equipment carries the mcs-Table field, the base station indicates that the user equipment configures an uplink 256QAM modulation mode, that is, uplink data is transmitted by using the uplink 256QAM modulation mode; if the RRC downlink message does not carry the mcs-Table field, the base station indicates that the user equipment is instructed to configure the uplink 256QAM modulation mode, that is, uplink data is not transmitted by using the uplink 256QAM modulation mode.
In a specific application, if the channel environment is poor, the uplink 256QAM modulation mode not only causes a higher modulation error rate, but also affects the data transmission rate, or if the channel environment is good, the user equipment transmits data using the uplink 64QAM modulation mode, which causes a waste of spectrum resources.
In order to solve the above problem, in the embodiment of the present invention, the ue may detect the channel environment in real time, and when detecting that the channel environment changes and determining that the current channel environment meets the uplink modulation mode switching condition, may send an uplink modulation mode switching request to the base station to switch the uplink modulation mode.
In an alternative embodiment of the present invention, the method may further include:
if it is determined that an uplink modulation mode switching request sent by a user equipment is received, responding to the uplink modulation mode switching request, switching the first uplink modulation mode into a second uplink modulation mode, and sending an RRC connection reconfiguration message to the user equipment; the RRC connection reconfiguration message carries a third field indicating to switch an uplink modulation mode.
In an application example of the present invention, assuming that a current uplink modulation mode of a user equipment is uplink 256QAM, the user equipment may detect a channel environment in real time, and when detecting that the channel environment is bad and is not suitable for using the uplink 256QAM modulation mode, it may determine that the current channel environment meets an uplink modulation mode switching condition, and may send an uplink modulation mode switching request to a base station, so as to switch the uplink modulation mode into uplink 64QAM, so that the uplink modulation mode is matched with the current channel environment. Or if the current uplink modulation mode of the user equipment is uplink 64QAM, and when the user equipment detects that the channel environment is better and is more suitable for using the uplink 256QAM modulation mode, it can be determined that the current channel environment meets the uplink modulation mode switching condition, and then an uplink modulation mode switching request can be sent to the base station to switch the uplink modulation mode to the uplink 256QAM, so as to achieve higher transmission efficiency and optimization of spectrum efficiency.
In an optional embodiment of the present invention, the determining that an uplink modulation mode switching request sent by the user equipment is received may specifically include: if the uplink data from the user equipment is detected to carry a fourth field indicating to switch the uplink modulation mode, determining to receive an uplink modulation mode switching request sent by the user equipment.
In the embodiment of the present invention, a fourth field for indicating to switch the uplink modulation mode may be newly added, and hereinafter, the fourth field is referred to as "MAC CE", through which the user equipment may request to the base station to configure/deconstruct the uplink 256QAM modulation mode.
In an application example of the present invention, the "MAC CE" may occupy 8 bits, and use the lowest bit of the 8 bits as a flag bit indicating switching of the uplink modulation mode, for example, if the lowest bit of the "MAC CE" is 1, it indicates that the uplink modulation mode needs to be switched.
In practical application, the ue may periodically evaluate the conditions of the cell signal and the channel environment to determine whether to switch the uplink modulation mode, and in the case that it is determined that the current environment meets the uplink modulation mode switching condition, may carry a fourth field "MAC CE" with a lowest bit of 1 in the uplink data to send an uplink modulation mode switching request to the base station.
The base station can determine that an uplink modulation mode switching request of the user equipment is received under the condition that the base station detects that uplink data of the user equipment carries a fourth field 'MAC CE' with the lowest bit of 1, and can switch to uplink 64QAM (second uplink modulation mode) if the current uplink modulation mode (first uplink modulation mode) is uplink 256 QAM; alternatively, if the current uplink modulation mode (the first uplink modulation mode) is uplink 64QAM, it may switch to uplink 256QAM (the second uplink modulation mode), and send an RRC connection reconfiguration message carrying a third field indicating to switch the uplink modulation mode to the user equipment to notify the user equipment to switch the uplink modulation mode.
The third field may specifically be a mcs-Table field in a PUSCH-Config structure, and if the RRC downlink message sent by the base station to the user equipment carries the mcs-Table field, the base station indicates that the user equipment configures an uplink 256QAM modulation mode, that is, switches the current uplink 64QAM modulation mode (the first uplink modulation mode) to an uplink 256QAM modulation mode (the second uplink modulation mode); if the RRC downlink message does not carry the mcs-Table field, the base station indicates that the user equipment is instructed to configure the uplink 256QAM modulation mode, that is, the current uplink 256QAM modulation mode (the first uplink modulation mode) is switched to the uplink 64QAM modulation mode (the second uplink modulation mode).
In a specific application, the uplink 64QAM modulation mode is used by default by the 5G network, and the uplink 256QAM modulation mode is supported by the user equipment, and the uplink 256QAM modulation mode can be used, so that the base station can automatically switch between the uplink 64QAM modulation mode and the uplink 256QAM modulation mode. If the 5G network can support an uplink modulation mode with a higher frequency spectrum, in order to instruct the base station to switch the uplink modulation mode to a target uplink modulation mode required by the user equipment, the embodiment of the present invention may further carry the target uplink modulation mode in the uplink modulation mode switching request, so as to instruct the base station user equipment to expect to switch the current uplink modulation mode to the target uplink modulation mode. After receiving the uplink modulation mode switching request of the user equipment, the base station can switch the uplink modulation mode to the target uplink modulation mode, and send an RRC connection reconfiguration message carrying a third field indicating the target uplink modulation mode to the user equipment, so as to inform the user equipment to switch the uplink modulation mode to the target uplink modulation mode.
In a specific application, after the base station issues an air interface RRC connection setup message/RRC connection restoration message/RRC connection reconfiguration message to the user equipment to indicate that the user equipment configures the first uplink modulation mode or switches to the second uplink modulation mode, the base station does not know the specific time when the user equipment receives the RRC connection setup message/RRC connection restoration message/RRC connection reconfiguration message, if the base station does not receive the RRC connection setup message/RRC connection restoration message/RRC connection reconfiguration message, the base station uses the configured first uplink modulation mode or the switched second uplink modulation mode to analyze uplink data, and at this time, the user equipment may not configure the first uplink modulation mode or switch to the second uplink modulation mode, and then the situation that uplink modulation modes configured on both sides of the user equipment and the base station are inconsistent may occur, which may result in failure of data analysis and further affect the accuracy of data transmission.
To solve the above problem, in an alternative embodiment of the present invention, after sending an RRC downlink message to the user equipment, the method may further include:
s11, analyzing uplink data according to an original uplink modulation mode before the first uplink modulation mode is configured;
Step S12, uplink scheduling control information carrying a first zone bit is sent to the user equipment so as to instruct the user equipment to send uplink data by using the original uplink modulation mode;
step S13, after receiving the RRC uplink response message returned by the UE aiming at the RRC downlink message, analyzing uplink data according to the first uplink modulation mode;
step S14, sending uplink scheduling control information carrying a second flag bit to the user equipment so as to instruct the user equipment to send uplink data by using the first uplink modulation mode.
In order to keep the uplink modulation modes at both sides of the user equipment and the base station synchronous, in the embodiment of the invention, a 1-bit flag bit is added in the uplink scheduling control information DCI (Downlink Control Information ) to indicate whether the user equipment keeps the original uplink modulation mode to send uplink data.
The first flag bit is used to indicate that the first uplink modulation mode is not validated after the user equipment configures the first uplink modulation mode, and the user equipment continues to keep the original uplink modulation mode to transmit uplink data, for example, when the user equipment detects that the newly added flag bit in the DCI information is 1, it indicates that the DCI information carrying the first flag bit is received, and then the user equipment continues to keep the original uplink modulation mode to transmit uplink data. The second flag bit is used for indicating that the user equipment can use the configured first uplink modulation mode to send uplink data, for example, when the user equipment detects that the newly added flag bit in the DCI information is 0, which indicates that the DCI information carrying the second flag bit is received, the user equipment can use the configured first uplink modulation mode to send uplink data.
In the following, a procedure of configuring an uplink 256QAM modulation mode for a user equipment by a base station is described as an example, and a procedure of configuring an uplink 256QAM modulation mode for a user equipment by a base station is similar and is referred to each other.
Specifically, the base station HL (High Layer) issues an air interface RRC connection establishment/RRC connection recovery/RRC connection reconfiguration message to the user equipment to instruct the user equipment to configure an uplink 256QAM modulation mode, and may also send an uplink 256QAM configuration instruction message to the base station MAC (Media Access Control, medium access control Layer), and after receiving the uplink 256QAM configuration instruction message, updating the uplink modulation mode into uplink 256QAM, wherein the uplink 256QAM modulation mode is not validated, and uplink scheduling control information carrying a first flag bit is sent to the user equipment to instruct the user equipment to continue to keep the original uplink modulation mode to send uplink data, and the base station MAC still keeps the original uplink 64QAM modulation mode to analyze the newly received uplink data.
After receiving the air interface RRC connection establishment/RRC connection restoration/RRC connection reconfiguration message issued by the base station, the user equipment may update the uplink modulation mode to uplink 256QAM. Because the DCI information received by the user equipment carries the first flag bit, the user equipment still uses the original uplink 64QAM modulation mode to transmit uplink data, and the configured uplink 256QAM modulation mode is not validated. Likewise, the RRC connection setup/RRC connection recovery/reconfiguration complete message sent by the user equipment to the base station is still sent using the uplink 64QAM modulation mode.
After receiving the corresponding air interface RRC connection establishment completion/RRC connection restoration completion/RRC connection reconfiguration completion message sent by the user equipment, the base station HL may determine that the user equipment has completed the configuration operation of the uplink 256QAM modulation mode, at this time, the base station HL may send an uplink 256QAM configuration completion indication message to the base station MAC, after receiving the uplink 256QAM configuration completion indication message, the base station MAC may send uplink scheduling control information carrying the second flag bit to the user equipment, so as to indicate that the user equipment may send uplink data using the configured uplink 256QAM modulation mode, and the base station MAC may parse the newly received uplink data using the configured uplink 256QAM modulation mode.
Therefore, the embodiment of the invention can keep the uplink modulation modes at both sides of the user equipment and the base station consistent, can reduce the occurrence of data analysis failure caused by the inconsistent uplink modulation modes at both sides of the user equipment and the base station, and can further improve the accuracy of data transmission.
In summary, the embodiment of the present invention may carry a reference threshold corresponding to a first uplink modulation mode in a system message broadcast by a base station to a user equipment, if the base station receives that an RRC uplink message from the user equipment carries a first field indicating the first uplink modulation mode, it indicates that the user equipment has a capability of supporting the first uplink modulation mode, and reference signal receiving power of a cell where the user equipment is currently located is suitable for using the first uplink modulation mode, so the base station may configure the first uplink modulation mode, and send, to the user equipment, an RRC downlink message carrying a second field indicating the first uplink modulation mode, to instruct the user equipment to configure the first uplink modulation mode.
It can be seen that, according to the embodiment of the present invention, in the process of establishing RRC connection between the ue and the base station, the base station can know whether the ue has the capability of supporting the first uplink modulation mode, so that the embodiment of the present invention can improve the efficiency of configuring the 256QAM modulation mode by the ue, and further can improve the transmission efficiency of uplink data. In addition, in the embodiment of the invention, the user equipment can actively recommend whether the first uplink modulation mode needs to be configured to the base station according to the self capacity and the reference signal receiving power of the current cell, so that the uplink modulation mode is more suitable for the current environment of the user equipment, and the optimization of the uplink modulation mode is realized.
Method embodiment II
Referring to fig. 2, a flowchart of a second embodiment of a message processing method of the present invention is shown and applied to a user equipment, where the method specifically may include:
In the embodiment of the present invention, the User Equipment (UE) may also be referred to as a mobile terminal, an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a User terminal, a wireless communication device, a User agent, or a User Equipment. An access terminal may be a cellular telephone, a cordless telephone, a SIP (SessionInitiation Protocol ) phone, a WLL (Wireless Local Loop, wireless local loop) station, a PDA (Personal Digital Assistant ), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5G network or a terminal device in a PLMN (Public Land Mobile Network ) network, etc.
The embodiment of the invention can carry the reference threshold corresponding to the first uplink modulation mode in the system message broadcast by the base station, and the reference threshold can be used for providing the judgment basis for judging whether the RSRP of the cell where the user equipment is currently located is suitable for the first uplink modulation mode or not. After receiving the system message broadcast by the base station, the ue may determine whether to recommend the base station to configure the first uplink modulation mode according to the RSRP of the cell in which the ue is currently located and a reference threshold carried in the system broadcast.
Specifically, if the ue has the capability of supporting the first uplink modulation mode in the current frequency band and detects that the reference signal received power of the current cell exceeds the reference threshold, which indicates that the ue is currently suitable for transmitting uplink data using the first uplink modulation mode, an RRC uplink message carrying a first field indicating the first uplink modulation mode may be sent to the base station. The first field is used for indicating that the base station currently recommends to use a first uplink modulation mode to transmit uplink data.
Under the condition that the base station detects that the received RRC uplink message carries the first field, the base station can determine that the user equipment supports a first uplink modulation mode, and the environment of the cell where the user equipment is currently located is also suitable for transmitting uplink data by using the first uplink modulation mode, so that the base station can send the RRC downlink message carrying the second field indicating the first uplink modulation mode to the user equipment so as to inform the user equipment of configuring the first uplink modulation mode.
The RRC uplink message may specifically include: an RRC connection setup request message or an RRC connection restoration request message. The RRC downlink message may specifically include: RRC connection setup message or RRC connection resume message.
And under the condition that the user equipment receives the RRC downlink message which is sent by the network equipment and carries the second field for indicating the first uplink modulation mode, the user equipment can configure the first uplink modulation mode in the user equipment.
It may be understood that the first uplink modulation mode may be an uplink 256QAM modulation mode or a higher uplink modulation mode, and for convenience of description, in the embodiment of the present invention, the first uplink modulation mode is taken as an example of the uplink 256QAM modulation mode, and other uplink modulation modes may be referred to each other.
In an alternative embodiment of the present invention, the method may further include:
step S21, if the current environment is determined to meet the uplink modulation mode switching condition, an uplink modulation mode switching request is sent to the network equipment;
step S22, receiving an RRC connection reconfiguration message sent by the network equipment aiming at the uplink modulation mode switching request;
step S23, if the RRC connection reconfiguration message carries a third field indicating the second uplink modulation mode, the first uplink modulation mode is switched to the second uplink modulation mode.
Specifically, the ue may detect the current environment, such as the signal of the cell and the channel environment in real time, so as to determine that the current environment meets the uplink modulation mode switching condition, and if so, may send an uplink modulation mode switching request to the base station to switch the current uplink modulation mode.
For example, assuming that the current uplink modulation mode of the ue is uplink 256QAM, when it is detected that the channel environment is degraded and is not suitable for using the uplink 256QAM modulation mode, it may be determined that the current environment meets the uplink modulation mode switching condition, and then an uplink modulation mode switching request may be sent to the base station to switch the uplink modulation mode to uplink 64QAM, so that the uplink modulation mode is matched with the current channel environment. Or if the current uplink modulation mode of the user equipment is uplink 64QAM, and when the user equipment detects that the channel environment is better and is more suitable for using the uplink 256QAM modulation mode, it can be determined that the current environment meets the uplink modulation mode switching condition, and then an uplink modulation mode switching request can be sent to the base station to switch the uplink modulation mode to the uplink 256QAM, so as to achieve higher transmission efficiency and optimization of spectrum efficiency.
In an optional embodiment of the present invention, the sending an uplink modulation mode switching request to the network device may specifically include: and sending uplink data carrying a fourth field for indicating to switch the uplink modulation mode to the network equipment.
Specifically, the embodiment of the present invention may newly add a fourth field for indicating to switch the uplink modulation mode, where the fourth field is hereinafter referred to as "MAC CE", through which the user equipment may request to the base station to configure/deconstruct the uplink 256QAM modulation mode. The "MAC CE" may occupy 8 bits, and in the embodiment of the present invention, the lowest bit of the 8 bits is used as a flag bit for indicating switching of the uplink modulation mode, for example, if the lowest bit of the "MAC CE" is 1, it indicates that the uplink modulation mode needs to be switched.
In practical application, the ue may periodically evaluate the conditions of the cell signal and the channel environment to determine whether to switch the uplink modulation mode, and if it is determined that the current environment meets the uplink modulation mode switching condition, the ue may carry a fourth field "MAC CE" with a lowest bit of 1 in the uplink data to send an uplink modulation mode switching request to the base station.
If the ue receives an RRC connection reconfiguration message sent by the base station and carrying a third field indicating to switch an uplink modulation mode, an operation for switching the uplink modulation mode may be performed, for example, if the current uplink modulation mode (the first uplink modulation mode) is uplink 256QAM, switching may be performed to uplink 64QAM (the second uplink modulation mode); alternatively, if the current uplink modulation mode (first uplink modulation mode) is uplink 64QAM, then it may be switched to uplink 256QAM (second uplink modulation mode).
In an alternative embodiment of the present invention, the method may further include:
if uplink scheduling control information carrying a first flag bit and sent by network equipment is received, uplink data is sent by using an original uplink modulation mode before the first uplink modulation mode is configured; or alternatively
And if the uplink scheduling control information carrying the second flag bit and transmitted by the network equipment is received, transmitting uplink data by using the first uplink modulation mode.
In order to keep the uplink modulation modes at both sides of the user equipment and the base station synchronous, the user equipment continues to transmit uplink data by using the original uplink modulation mode before the first uplink modulation mode is configured under the condition that the uplink scheduling control information carrying the first flag bit and transmitted by the base station is received. And under the condition that the user equipment receives the uplink scheduling control information carrying the second flag bit and sent by the base station, the uplink data can be sent by using the first uplink modulation mode.
Therefore, the embodiment of the invention can keep the uplink modulation modes at both sides of the user equipment and the base station consistent, can reduce the occurrence of data analysis failure caused by the inconsistent uplink modulation modes at both sides of the user equipment and the base station, and can further improve the accuracy of data transmission.
In summary, the embodiment of the present invention may carry a reference threshold corresponding to a first uplink modulation mode in a system message broadcast by a base station to a user equipment, if the user equipment supports the first uplink modulation mode and the reference signal receiving power of a cell where the user equipment is located exceeds the reference threshold, an RRC uplink message carrying a first field indicating the first uplink modulation mode may be sent to the network equipment, so that the network equipment configures the first uplink modulation mode, and if the user equipment receives an RRC downlink message carrying a second field indicating the first uplink modulation mode sent by the base station, which indicates that the base station has already configured the first uplink modulation mode, the user equipment may also configure the first uplink modulation mode.
It can be seen that, according to the embodiment of the present invention, in the process of establishing RRC connection between the ue and the base station, the base station can know whether the ue has the capability of supporting the first uplink modulation mode, so that the embodiment of the present invention can improve the efficiency of configuring the 256QAM modulation mode by the ue, and further can improve the transmission efficiency of uplink data. In addition, in the embodiment of the invention, the user equipment can actively recommend whether the first uplink modulation mode needs to be configured to the base station according to the self capacity and the reference signal receiving power of the current cell, so that the uplink modulation mode is more suitable for the current environment of the user equipment, and the optimization of the uplink modulation mode is realized.
