Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings, the described embodiments should not be construed as limiting the present invention, and all other embodiments obtained by a person of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and that the technical solutions described in the embodiments of the present invention may be combined with each other without conflict.

Before describing the technical solution of the embodiment of the present invention, the following description will be made on the related art.

Currently, for a terminal supporting dual connectivity mode, such as LTE-5G New air interface (NR), the terminal has three power configuration parameters, which include P-Max, P-maxetra, and P-NR-FR1. Wherein, P-Max represents the maximum transmission power supported by a pure terminal, and can be configured by a system message block-SIB 1 in a system message when the terminal is in an LTE network, and can be configured by a system message block-SIB 2 in a system message when the terminal is in a 5G network; P-MaxEUTRA represents the maximum transmission power of the terminal in the LTE network (4G network), which can be referred to as LTE power for short; P-NR-FR1 indicates the maximum transmission power of a terminal in a 5G network in a Frequency Range (FR) 1, which may be referred to as 5G power.

In the related art, in consideration of the power index requirements of the FDD terminal, the terminal may be generally allocated with a corresponding power configuration in advance, for example, the existing terminal power configuration is: if the terminal is a Non-Standalone Networking (NSA) terminal, configuring as [ P-Max, P-MaxEUTRA, P-NR-FR1] = [23, 20, 20]; if the terminal is a stand-alone network (SA) terminal, the configuration is P-Max =26.

Taking the terminal as an NSA terminal as an example, however, when the terminal is in an LTE only mode, such as in a voice service scenario supported by VOLTE, due to a decrease in LTE power allocated to the terminal, coverage performance of the terminal is decreased, thereby affecting service quality when the terminal in the LTE network performs data service, and if the terminal is in a voice service scenario supported by VOLTE, due to a decrease in LTE power allocated to the terminal, a Mean Opinion Score (MOS) of VOLTE (which is an important index for measuring voice quality of a communication system) is decreased, thereby decreasing VOLTE service performance. This is because the maximum transmit power supported by the pure terminal is 23dBm, but to ensure that the maximum transmit power of the terminal cannot exceed 23dBm, the maximum transmit power of the LTE side and the 5GNR side of the terminal are configured to be 20dBm, i.e. the LTE power of the terminal is 3dB lower than the maximum transmit power supported by the pure terminal.

At present, in the related art, the problem can be solved by sharing the LTE power and the 5G power of the terminal, that is, the terminal realizes dynamic allocation of the 5G power and the LTE power through hardware and software functions, but the terminal in the scheme needs higher hardware capability support and higher cost, and not all the existing commercial terminals support this function. Therefore, no effective solution exists at present for the problem of service quality reduction caused by the power configuration of the existing terminal when the terminal of the LTE network performs data service.

Based on this, in various embodiments of the present invention, the terminal adjusts the power in the first network system to be the first power and adjusts the power in the second network system to be the second power through the indication of the first information; the first power is the maximum power supported by the terminal, and the uplink data service cannot be performed at the second power.

By adopting the scheme of the embodiment of the invention, the power of the terminal in the first network system and the power of the terminal in the second network system are reconfigured through the indication of the first information, namely the power (such as LTE power) of the first network system is adjusted to the maximum power supported by the terminal, and the power (such as 5G power) of the second network system is adjusted to the maximum power not supporting the uplink data service.

The present invention will be described in further detail with reference to the accompanying drawings and examples.

An embodiment of the present invention provides an information transmission method, where the method is applied to a first base station, and fig. 1 is a schematic flow diagram of the information transmission method on the first base station side provided in the embodiment of the present invention, and as shown in fig. 1, the method includes:

step 101, the first base station determines first information.

Step 102, sending first information to a terminal, wherein the first information is used for indicating the terminal to adjust the power in a first network system to be a first power and adjust the power in a second network system to be a second power; the first power is the maximum power supported by the terminal, and the uplink data service cannot be performed under the second power.

Here, the terminal supports a dual connection mode in which the terminal communicates with both the first base station and the second base station; the first base station is a main base station, and the second base station is an auxiliary base station. Under a first network system, a terminal communicates with a first base station; and under the second network system, the terminal is communicated with the second base station.

In the embodiment of the present invention, the terminal supports the dual connectivity mode, which can be understood as that the terminal can support two different types of network systems, that is, the terminal has a dual-transmission function for supporting two different types of network systems. Here, the dual connectivity mode supported by the terminal may be an LTE-5G NR dual connectivity mode, in which the terminal may communicate with the first base station, that is, an eNB (LTE base station) corresponding to the LTE network, and may communicate with the second base station, that is, a GNR network, that is, a gNB (NR base station). At this time, the first network standard may be an LTE network, and the second network standard may be a 5GNR network.

Because the existing terminal power configuration can cause the service quality reduction when the terminal of the LTE network carries out data service, in order to solve the technical problem, in practical application, the first base station sends first information to the terminal, the terminal adjusts the power of the first network system, namely the LTE power, to be the first power through the indication of the first information, and adjusts the power of the second network system, namely the 5G power, to be the second power; the first power is the maximum power supported by the terminal, and the uplink data service cannot be performed at the second power.

Here, the first information sent by the first base station to the terminal may be RRC reconfiguration information; that is to say, the embodiment of the present invention may reconfigure the LTE power and the 5G power of the terminal through the RRC reconfiguration information, so that the reconfigured LTE power is the maximum power supported by the terminal, and the reconfigured 5G power cannot support the uplink data service. Therefore, when the terminal is in the LTE only mode, the LTE power distributed to the terminal is greatly improved, so that the coverage performance of the terminal is improved, and the service quality of the terminal in the LTE network during data service can be improved.

For example, taking the aforementioned existing terminal power configuration as [ P-Max, P-maxeeutra, P-NR-FR1] as [23, 20, 20], when the terminal is in LTE only mode, such as in voice service scenario supported by VOLTE, the uplink data service of 5G is not required. Therefore, the RRC reconfiguration information is sent to the terminal through the first base station (LTE base station), and the RRC reconfiguration information may carry therein power adjustment indication information, where the power adjustment indication information is used to instruct the terminal to adjust the power in the first network system and the power in the second network system, that is, to adjust the LTE power and the 5G power, and specifically may be used to instruct the terminal to reconfigure P-maxeeutra, P-NR-FR1 from [20, 20] to [23,0] accordingly.

The system comprises a base station, a mobile station and a mobile terminal, wherein P-MaxEUTRA can be reconfigured in LTE based on RRC reconfiguration information; P-NR-FR1 is included in LTE in NR-secondary cell group configuration (NR-secondary cell group pconfig) in RRC Connection Reconfiguration (RRC Connection Reconfiguration) information, where the NR-secondary cell group pconfig includes RRC Reconfiguration information of 5GNR, and the RRC Reconfiguration (rrcrconfiguration) information of 5GNR carries reconfigured 5G power.

Therefore, the adjusted LTE power, that is, the first power is the maximum power supported by the terminal, the service quality meets the preset condition when the data service is performed at the first power, and the uplink data service cannot be performed at the adjusted 5G power, that is, the second power. Therefore, the service quality of the terminal in the LTE network during data service can be improved.

In practical application, after the first base station sends the first information to the terminal, because the first information indicates that the adjusted 5G power cannot perform the uplink data service, based on this, the first base station no longer issues the uplink scheduling signaling of 5G NR to the terminal. And the terminal can initiate uplink service, such as uplink voice service, in the LTE by using the reconfigured single-sided power.

Based on this, in some embodiments, the method further comprises: receiving a voice service data packet sent by the terminal based on the first power; and carrying out data packet processing on the voice service data packet.

Specifically, the terminal sends the voice service data packet to the first base station based on the reconfigured first power, and after receiving the voice service data packet, the first base station may perform operations such as forwarding, further analyzing, and the like on the voice service data packet.

In some embodiments, the first base station may send the first information to the terminal by: and sending the first information to the terminal through high-level signaling.

Here, the higher layer signaling may be RRC signaling or Media Access Control (MAC) signaling, etc.

In practical application, when the first base station detects that the first trigger condition is met, the first base station may be triggered to send the first information to the terminal, so that the terminal reconfigures the LTE power and the 5G power of the terminal based on the first information.

Based on this, in some embodiments, the sending the first information to the terminal includes:

the first trigger condition comprises one of:

the terminal initiates a data service in the first network system;

Here, when the first base station detects that the terminal is in the LTE only mode, that is, initiates a data service, such as a VOLTE service, in the LTE only mode, the first base station may be triggered to send the first information to the terminal; or, when the first base station detects that the communication link between the terminal and the second base station is disconnected, specifically, a Secondary Cell Group (SCG) within the coverage area of the second base station is disconnected, resulting in no user plane data for 5G, at this time, the first base station may be triggered to send the first information to the terminal; or, in a offloading scenario, to ensure LTE performance, the offloading policy is configured to only support data stream transmission in the LTE network but not support data stream transmission in the 5G network, and at this time, the first base station may be triggered to send the first information to the terminal based on the offloading policy.

In practical application, since the first information indicates the terminal to adjust the power in the second network type to the second power, and the terminal cannot perform the uplink data service at the second power, in this case, there is no 5G NR uplink data transmission, but there may be 5G NR downlink data transmission; that is, in the process of performing VOLTE service in LTE, the second base station, i.e., the gNB (NR base station) corresponding to the 5G NR network, may send a data packet to the terminal, but in order to ensure correct Transmission of Transmission Control Protocol (TCP) service, the data packet (downlink service) sent by the second base station needs uplink feedback, that is, the data packet can be fed back by the first base station, so as to improve the rate of the 5G NR concurrent downlink data service.

Based on this, in some embodiments, the method further comprises: and sending second information to the terminal, wherein the second information is used for indicating the terminal to acquire that uplink feedback data of a data packet sent by the second base station is carried by the PUCCH of the first base station.

Here, the PUCCH of the first base station can support feedback of Uplink Control Information (UCI) including at least one of: channel State Information (CSI) of DownLink (DL), scheduling Request (SR) Information of a terminal, acknowledgement (ACK) message (which may also be referred to as an Acknowledgement message), and Negative-Acknowledgement (NACK) message (which may also be referred to as a non-Acknowledgement message).

In practical application, the first base station sends the second information to the terminal, and the second information can be sent by the following method:

sending the second information to the terminal through a high-level signaling; the high-level signaling at least comprises RRC signaling, and the RRC signaling carries PUCCH configuration information.

Here, PUCCH configuration information of the first base station and the second base station of the same terminal may be distinguished by cyclic Shift (cyclic Shift) or deltaPUCCH-Shift.

In practical application, the uplink feedback data of the data packet sent by the second base station and the data packet sent by the first base station are carried by the same resource in the PUCCH of the first base station.

Here, the uplink feedback data of the data packet transmitted by the second base station and the data packet transmitted by the first base station may be carried by the same resource in the PUCCH of the first base station by using a hybrid coding scheme.

In some embodiments, the method further comprises:

Here, the first encoding method and the second encoding method may be one of Binary Phase Shift Keying (BPSK) encoding methods, quadrature Phase Shift Keying (QPSK) encoding methods, and the like, and the embodiment of the present invention is not limited thereto.

In some embodiments, the method further comprises: sending third information to the terminal;

In actual application, when the first base station detects that the second trigger condition is met, the first base station may be triggered to send third information to the terminal, so that the terminal reconfigures the LTE power and the 5G power of the terminal based on the third information again.

Based on this, in some embodiments, the sending the third information to the terminal includes:

when detecting that a second trigger condition is met, triggering the first base station to send the third information to the terminal based on the second trigger condition;

wherein the second trigger condition comprises one of:

the data service of the terminal under the first network system is finished;

the communication link between the terminal and the second base station is in a normal connection state;

the offloading policy is configured to support data streaming in the second network type and support data streaming in the first network type.

Here, when the first base station detects that the data service initiated by the terminal, such as the VOLTE service, ends, the first base station may be triggered to send the third information to the terminal; or, when the first base station detects that the SCG recovers the user plane data, the first base station can be triggered to send third information to the terminal; or, triggering the first base station to send the third information to the terminal based on the configuration of the offloading policy.

Still taking the first information as the RRC reconfiguration information as an example, in actual application, the first base station sends the RRC reconfiguration information to the terminal, and the terminal receives the RRC reconfiguration information and reconfigures P-maxeeutra, P-NR-FR1 from [20, 20] to [23,0] accordingly based on the RRC reconfiguration information. However, when the first base station detects that the VOLTE service initiated by the terminal is ended, or the SCG recovers the user plane data, the first base station may send RRC reconfiguration information to the terminal again, where the RRC reconfiguration information carries power adjustment indication information, where the power adjustment indication information is used to indicate that the terminal adjusts the power in the first network system from the first power to the third power, and adjusts the power in the second network system from the second power to the fourth power, and specifically, may be used to indicate that the terminal reconfigures P-maxeeutra, P-NR-FR1 from [23,0] to [20, 20] accordingly.

In some embodiments, the first base station may send the third information to the terminal by: and sending the third information to the terminal through high-level signaling.

Here, the higher layer signaling may be RRC signaling or MAC signaling, etc.

Correspondingly, an embodiment of the present invention further provides an information transmission method, where the method is applied to a terminal, and fig. 2 is a schematic flow chart of the information transmission method on the terminal side provided in the embodiment of the present invention, and as shown in fig. 2, the method includes:

step 201, the terminal receives first information.

Here, the terminal supports a dual connectivity mode, in which the terminal communicates with both a first base station and a second base station, where the first base station is a primary base station and the second base station is a secondary base station.

In some embodiments, the terminal may receive the first information by: the first information is received through higher layer signaling.

Here, the higher layer signaling may be RRC signaling or MAC signaling, etc.

In actual application, when the terminal detects that the first trigger condition is met, the terminal can trigger to receive the first information.

Based on this, in some embodiments, the receiving first information comprises:

when detecting that a first trigger condition is met, triggering to receive the first information based on the first trigger condition;

the first trigger condition comprises one of:

the terminal initiates a data service in the first network type;

Here, when it is detected that the terminal is in the LTE only mode, that is, a data service, such as a VOLTE service, is initiated in the LTE only mode, the receiving of the first information may be triggered; or, when it is detected that the communication link between the terminal and the second base station is disconnected, specifically, the SCG within the coverage of the second base station is disconnected, resulting in no user plane data for 5G, at this time, the first information may be triggered to be received; or, in an offloading scenario, to ensure LTE performance, the offloading policy is configured to only support data stream transmission in the LTE network, but not to support data stream transmission in the 5G network, and at this time, the first information may be triggered and received based on the offloading policy.

Step 202, based on the first information, adjusting the power in the first network system to be a first power, and adjusting the power in the second network system to be a second power, where the first power is a maximum power supported by the terminal, and the uplink data service cannot be performed at the second power.

Here, in the first network system, the terminal communicates with the first base station; and under the second network system, the terminal is communicated with the second base station.

Because the existing terminal power configuration can cause the service quality reduction when the terminal of the LTE network carries out data service, in order to solve the technical problem, in actual application, the terminal adjusts the power in a first network system, namely the LTE power, to be a first power and adjusts the power in a second network system, namely the 5G power, to be a second power based on first information sent by a first base station; the first power is the maximum power supported by the terminal, and the uplink data service cannot be performed at the second power.

Here, the first information received by the terminal may be RRC reconfiguration information; that is to say, the embodiment of the present invention may reconfigure the LTE power and the 5G power of the terminal through the RRC reconfiguration information, so that the reconfigured LTE power is the maximum power supported by the terminal, and the reconfigured 5G power cannot support the uplink data service. Therefore, when the terminal is in the LTE only mode, the LTE power distributed to the terminal is greatly improved, so that the coverage performance of the terminal is improved, and the service quality of the terminal in the LTE network during data service can be improved.

In practical application, the terminal may use the reconfigured single-sided power, that is, the reconfigured LTE power initiates an uplink service, such as an uplink voice service, in LTE.

Based on this, in some embodiments, the method further comprises: transmitting a voice service data packet to the first base station based on the first power; and receiving a processing result of the first base station on the voice service data packet.

In practical application, since the first information indicates the terminal to adjust the power in the second network type to the second power, and the terminal cannot perform the uplink data service at the second power, in this case, there is no 5G NR uplink data transmission, but there may be 5G NR downlink data transmission; that is to say, in the process of performing VOLTE service in LTE, the second base station, that is, the gNB (NR base station) corresponding to the 5G NR network, may send a data packet to the terminal, but in order to ensure correct transmission of TCP service, the data packet (downlink service) sent by the second base station needs uplink feedback, that is, feedback may be sent by the first base station, so as to improve the rate of the 5G NR concurrent downlink data service.

Based on this, in some embodiments, the method further comprises: receiving second information; and acquiring that uplink feedback data of the data packet sent by the second base station is carried by the PUCCH of the first base station based on the second information.

Here, the PUCCH of the first base station can support feedback of UCI, and the UCI information includes at least one of: CSI of DL, uplink SR information of the terminal, ACK message, NACK message.

Wherein, CSI periodic reporting (report) for LTE and NR can be configured to different periods, namely, NR CSI-report and LTE CSI-report are configured to different periods; or the NR CSI-report and the LTE CSI-report are configured to have the same period but different offset values (offsets), however, when there is a conflict between the NR CSI-report and the LTE CSI-report, since the reconfigured LTE power indicated by the first information is the maximum power supported by the terminal and the reconfigured 5G power cannot support uplink data traffic, the LTE CSI-report may be selected and the NR CSI-report may be discarded.

In practical application, the terminal receives the second information, and the second information can be realized by the following modes:

Here, PUCCH configuration information of the LTE base station and the NR base station of the same terminal may be distinguished by cyclic Shift or deltaPUCCH-Shift.

Specifically, under the LTE network, by adding NRPUCCH-Config related information, such as cyclic Shift or deltaPUCCH-Shift, to LTE RRC signaling, PUCCH configuration information of an LTE base station and an NR base station is distinguished, so that uplink feedback data of downlink service data transmitted by NR is carried through PUCCH of the LTE base station.

For example, the PUCCH configuration information of the NR base station may be configured by adding an NR PUCCH-configuration within an NR-subcordarylgroupconfig in the RRC Connection Reconfiguration information of LTE; or may be determined by adding NR base station related PUCCH configuration information within the RRC PUCCH-Config message of LTE.

In practical application, the terminal receives second information sent by the LTE base station, and then based on the second information, the uplink feedback data of the data packet sent by the NR base station is acquired to be carried by the PUCCH of the LTE base station. Specifically, when the NR PUCCH-Config configuration in the LTE RRC signaling is empty, uplink feedback data of a data packet sent by the NR base station is carried by the PUCCH of the NR base station; on the contrary, when the NR PUCCH-Config configuration in the LTE RRC signaling is not empty, the uplink feedback data of the data packet sent by the NR base station is carried by the PUCCH of the LTE base station.

In practical application, uplink feedback data of a data packet sent by an NR base station is determined by distinguishing PUCCH configuration information of the same terminal in an LTE base station and the NR base station, but since PUCCH resources are not continuously allocated and coded, a Peak-to-Average power ratio (PAPR) of an uplink of the terminal may be higher, thereby affecting uplink performance of the terminal.

Based on this, in practical application, the uplink feedback data of the data packet sent by the second base station and the data packet sent by the first base station are carried by the same resource in the PUCCH of the first base station.

Here, the uplink feedback data of the data packet transmitted by the second base station and the data packet transmitted by the first base station may be carried by the same resource in the PUCCH of the LTE base station, which is the first base station, by using a hybrid coding scheme, so as to solve the problem that the uplink performance of the terminal is reduced due to a high PAPR of the uplink of the terminal in the above scheme.

In some embodiments, the method further comprises:

Here, the first coding scheme and the second coding scheme may be one of coding schemes such as BPSK and QPSK, but the present invention is not limited thereto.

For example, the terminal may encode ACK/NACK sent by the LTE base station in a BPSK manner to obtain third encoded data, encode uplink feedback data of a data packet sent by the NR base station in a QPSK manner, such as ACK/NACK, to obtain second encoded data, and send the second encoded data and the third encoded data. For another example, uplink feedback data, such as ACK/NACK, of a data packet sent by the NR base station is concatenated with ACK/NACK sent by the LTE base station to obtain concatenated data, and the concatenated data is encoded to obtain first encoded data, and the first encoded data is sent. The encoding method for encoding the concatenated data is not limited.

In some embodiments, the method further comprises: receiving third information; based on the third information, adjusting the power in the first network system from the first power to a third power, and adjusting the power in the second network system from the second power to a fourth power; the third power is preconfigured by the first base station, and the fourth power is preconfigured by the second base station.

In actual application, when the terminal detects that the second trigger condition is met, the terminal may trigger to receive third information, and the terminal may reconfigure the LTE power and the 5G power again based on the third information.

Based on this, in some embodiments, the receiving third information includes:

when a second trigger condition is detected to be met, triggering to receive the third information based on the second trigger condition;

wherein the second trigger condition comprises one of:

the data service of the terminal under the first network system is ended;

the offloading policy is configured to support data stream transmission in the second network system and support data stream transmission in the first network system.

In some embodiments, the terminal may receive the third information by: receiving the third information through a higher layer signaling.

Here, the higher layer signaling may be RRC signaling or MAC signaling, etc.

By adopting the scheme of the embodiment of the invention, the power of the terminal in the first network system and the power of the terminal in the second network system are reconfigured through the indication of the first information, namely the power (such as LTE power) of the first network system is adjusted to the maximum power supported by the terminal, and the power (such as 5G power) of the second network system is adjusted to the maximum power not supporting the uplink data service.

The present invention will be described in further detail with reference to the following application examples.

step 401, when detecting that the NSA terminal initiates the VOLTE service, the lte base station triggers to send first information to the NSA terminal.

Here, the first information may be RRC reconfiguration information, and power adjustment indication information may be carried in the RRC reconfiguration information, where the power adjustment indication information is used to instruct the NSA terminal to adjust power in the LTE network and power in the 5G network, that is, to adjust LTE power and 5G power.

In step 402, the nsa terminal receives first information transmitted by the LTE base station.

Step 403, the nsa terminal adjusts the power in the LTE network to be the first power and adjusts the power in the 5G network to be the second power based on the first information; the first power is the maximum power supported by the terminal, and the uplink data service cannot be performed at the second power.

According to the embodiment of the invention, the LTE power and the 5G power of the terminal can be reconfigured through the RRC reconfiguration information, so that the reconfigured LTE power is the maximum power supported by the terminal, and meanwhile, the reconfigured 5G power cannot support uplink data services.
