Detailed Description

Before the technical solution of the embodiment of the present invention is introduced, a description is given of a related art.

In a fifth Generation (5G) mobile communication system, in order to improve an uplink coverage and an uplink data transmission rate, a plurality of uplink carriers may be configured in a cell by an uplink enhancement technique, that is, an uplink and downlink decoupling technique, and a carrier used for supplementing uplink transmission among the plurality of uplink carriers is referred to as a SUL carrier. Generally, the configuration and scheduling of the SUL carrier and the New Radio interface (NR) carrier are implemented by the network side, and on one hand, if the network side performs targeted configuration and scheduling for the state of each user in a cell, the processing overhead and complexity of the network side may be increased; on the other hand, if the network side adopts a carrier configuration and scheduling scheme with unified cells, the transmission requirements of the terminal users cannot be met in a targeted manner, the user experience is affected, and the waste of network resources is also caused.

Based on this, in various embodiments of the present invention, carrier scheduling recommendation information is generated; sending the generated carrier scheduling suggestion information to network equipment; and the carrier scheduling suggestion information is used for the network equipment to make scheduling decision on the carrier carrying uplink transmission.

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, as shown in fig. 1, the method includes:

step 101: generating carrier scheduling suggestion information;

step 102: sending the generated carrier scheduling suggestion information to network equipment; and the carrier scheduling suggestion information is used for the network equipment to make scheduling decision on the carrier carrying uplink transmission.

Here, in step 101, in the case that at least two uplink carriers are configured for the terminal by the uplink enhanced technique, the terminal may generate carrier scheduling suggestion information. For example, in a 5G system, when the NR carrier and the SUL carrier are configured for the terminal by the uplink enhanced technique, the terminal may generate carrier scheduling suggestion information.

Here, in step 102, the generated carrier scheduling suggestion information may be transmitted to the network device through a first signaling. The first signaling may specifically be Radio Resource Control (RRC) signaling.

In practical application, when the terminal performs uplink transmission with the network side, when the terminal considers how to suggest the network side to select a carrier for carrying the uplink transmission, the considered factors include: the transmission delay of the service, the signal quality of the carrier carrying the uplink transmission, the uplink transmission power used for transmitting the service, the uplink transmission data volume corresponding to the service, the electric quantity of the terminal and the like.

Based on this, in an embodiment, the generating carrier scheduling suggestion information includes:

The following describes in detail how the terminal generates the carrier scheduling suggestion information differently.

In case 1, the terminal generates carrier scheduling suggestion information based on the transmission delay requirement of the current service.

In practical application, when the type of the service transmitted between the terminal and the network side is a live broadcast service, the service needs to satisfy low-delay transmission, so the terminal can suggest that the network side selects a carrier capable of shortening the service transmission delay from at least two uplink carriers.

Based on this, in an embodiment, the generating carrier scheduling suggestion information based on at least one of a transmission delay requirement of a current service, a signal quality of an uplink carrier, uplink transmission power, and an uplink transmission data amount includes:

judging whether the current service requires low-delay transmission;

The carrier types selected by the network side are suggested as follows: an SUL carrier; the reason for the suggestion is that: current services require low latency transmission.

Here, since the SUL carrier operates in a Frequency Division Duplex (FDD) mode, that is, the uplink and the downlink operate using two separate frequencies, if the SUL carrier is used to carry uplink transmission, services can be simultaneously transmitted in a plurality of uplink timeslots corresponding to the SUL carrier, and thus, the service transmission delay can be shortened.

In practical application, the method for judging whether the current service requires low-delay transmission includes one of the following steps:

matching the current service with a preset type to obtain a matching result; if the matching result represents that the current service is matched with the preset type, determining that the current service requires low-delay transmission;

determining a first Quality of Service (QoS) corresponding to the current Service according to the corresponding relation between the Service configured on the network side and the QoS; when the first QoS meets a preset condition, determining that the current service requires low-delay transmission;

determining a first network slice corresponding to the current service according to the corresponding relation between the service configured on the network side and the network slice; and when the first network slice requires low-delay transmission service, determining that the current service requires low-delay transmission.

For example, assuming that the preset type is a live broadcast service type, if the current service is a browsing service, it is determined that the current service does not require low-latency transmission because the current service type is not matched with the preset type. Or determining a first QoS corresponding to the current service according to a corresponding relation between the service configured on the network side and the QoS, and if the value of the first QoS is 10 and the value of the first QoS is greater than a preset threshold, determining that the current service requires low-delay transmission; otherwise, determining that the current service does not require low-delay transmission. Or, determining a first network slice corresponding to the current service according to the corresponding relation between the service configured on the network side and the network slice, and if the first network slice requires the low-delay transmission service, determining that the current service requires the low-delay transmission; the first network slice may refer to one of a plurality of network resources obtained by dividing network resources.

In an example, taking a 5G system as an example, as shown in fig. 2, a process that a terminal generates carrier scheduling suggestion information and sends the carrier scheduling suggestion information to a network device is described, including:

step 201: the terminal judges whether the current service requires low-delay transmission; when it is determined that the current service requires low-latency transmission, step 202 is performed:

here, when the terminal opens a certain application program to perform uplink/downlink data transmission, it is determined whether the current service requires Low-Latency transmission, and if the service executed by the opened application program is a service in a high-reliability Low-Latency communication (URLLC) scenario, the terminal determines that the current service requires Low-Latency transmission.

Step 202: the terminal generates carrier scheduling suggestion information; the carrier scheduling suggestion information comprises a suggestion of selecting SUL carrier to carry uplink transmission and a suggestion reason.

The carrier types selected by the network side are suggested as follows: SUL carriers, the reason for proposal is: current services require low latency transmission.

Step 203: and the terminal sends the generated carrier scheduling suggestion information to the network equipment.

Here, the network device may determine an uplink carrier scheduling manner for the terminal according to carrier scheduling suggestion information sent by the terminal and in combination with factors such as channel quality, signal strength, load condition, network scheduling complexity, and the like of an NR carrier and an SUL carrier that is an additional uplink carrier of the NR carrier.

It should be noted that, the NR carrier may provide more uplink transmission resources and transmission rates than the SUL carrier, and the network device schedules the NR carrier to carry uplink transmission with higher priority than the SUL carrier.

Fig. 3 is a schematic diagram of SUL carriers, and as shown in fig. 3, the frequency of SUL carriers is lower than that of NR carriers, for example, the NR carrier is 2.6GHz and the SUL carrier is 1.8 GHz.

Here, the terminal generates the carrier scheduling suggestion information based on the transmission delay of the current service of the terminal, and has the following advantages:

because the SUL carrier adopts the operating mode of FDD frequency band, that is, the SUL carrier realizes continuous uplink transmission in a plurality of corresponding uplink time slots, that is, services can be simultaneously transmitted in a plurality of uplink time slots corresponding to the SUL carrier, and the NR carrier adopts the operating mode of TDD frequency band, that is, services cannot be simultaneously transmitted in a plurality of uplink time slots corresponding to the NR carrier, therefore, when the terminal determines that the current service requires low-delay transmission, the network side is recommended to select the SUL carrier to carry the uplink transmission, and the feedback of downlink data and the uplink data transmission can be completed in the shortest time, thereby playing a role in shortening the delay.

And 2, the terminal generates carrier scheduling suggestion information based on the transmission delay requirement of the current service and the signal quality of the uplink carrier.

In practical application, when the service transmitted between the terminal and the network side is a browsing service, since the service does not need low-delay transmission, if the signal quality of the uplink carrier is low, the network side may be recommended to select a supplementary carrier of the uplink carrier, i.e., an SUL carrier, to carry the uplink transmission.

judging whether the current service requires low-delay transmission;

Here, the carrier types proposed for selection by the network side are: an SUL carrier; the reason for the suggestion is that: the signal quality of the uplink carrier is less than or equal to a signal quality threshold.

In an example, taking a 5G system as an example, as shown in fig. 4, a process that a terminal generates carrier scheduling suggestion information and sends the carrier scheduling suggestion information to a network device is described, including:

step 401: the terminal judges whether the current service requires low-delay transmission; when it is determined that the current service does not require low latency transmission, perform step 402;

step 402: the terminal measures the signal quality of the uplink carrier;

step 403: the terminal judges whether the signal quality of the uplink carrier is less than or equal to a signal quality threshold value; when the signal quality of the uplink carrier is less than or equal to a signal quality threshold, executing step 404;

in the 5G system, the uplink carrier may refer to an NR carrier. The terminal may obtain the signal quality threshold through a system message.

Step 404: the terminal generates carrier scheduling suggestion information; the carrier scheduling suggestion information comprises a suggestion of selecting SUL carrier to carry uplink transmission and a suggestion reason.

The carrier types selected by the network side are suggested as follows: an SUL carrier; the reason for the suggestion is that: the signal quality of the uplink carrier is below a signal quality threshold.

Step 405: and the terminal sends the generated carrier scheduling suggestion information to the network equipment.

Here, the network device may determine an uplink carrier scheduling manner for the terminal according to carrier scheduling suggestion information sent by the terminal, and by combining factors such as channel quality, signal strength, load condition, and network scheduling complexity of an NR carrier and a SUL carrier that is a supplementary carrier of the NR carrier.

Here, the terminal generates the carrier scheduling suggestion information based on the transmission delay of the current service and the signal quality of the uplink carrier, and has the following advantages:

because the frequency of the SUL carrier is lower than that of the NR carrier, and the propagation loss of the SUL carrier is smaller than that of the NR carrier, when the terminal determines that the current service does not require low-delay transmission and the signal quality of the NR carrier is lower than the signal quality threshold, it is recommended that the network side selects the SUL carrier to carry uplink transmission, which can effectively improve the edge rate of uplink transmission and improve the uplink transmission performance of edge users.

In practical application, when the service transmitted between the terminal and the network side is a browsing service, since the service does not need low-delay transmission, if the signal quality of the uplink carrier is high, the network side can be recommended to select the carrier type for carrying the uplink transmission in combination with the uplink transmission power and the uplink transmission data amount.

judging whether the current service requires low-delay transmission;

And case 3, under the condition that the uplink transmission power is less than the maximum transmission power configured at the network side, the terminal generates carrier scheduling suggestion information based on the transmission delay requirement of the current service, the signal quality of the uplink carrier, the uplink transmission power and the uplink transmission data volume.

In practical application, if the signal quality of the uplink carrier is high, the terminal may recommend the network side to select the carrier type for carrying the uplink transmission in combination with the uplink transmission power and the uplink transmission data amount. The terminal can estimate the uplink transmission power corresponding to the current service by combining the acquired open-loop control parameters, the current moving speed of the terminal and the like, if the estimated uplink transmission power does not reach the maximum transmitting power configured by the network side, namely the influence of radiation generated by the terminal on a user is low, under the condition, if the uplink transmission data volume corresponding to the current service is large, the network side can be recommended to select an uplink carrier and a supplementary carrier of the uplink carrier, namely an SUL carrier, to jointly carry uplink transmission; if the uplink transmission data volume corresponding to the current service is small, the network side can be recommended to preferentially select the uplink carrier to carry the uplink transmission.

Based on this, in an embodiment, the generating carrier scheduling suggestion information based on the uplink transmission power and the uplink transmission data amount corresponding to the current service includes:

estimating uplink transmission power corresponding to the current service;

The carrier types selected by the network side are suggested as follows: SUL carriers and uplink carriers. The reason for the suggestion is that: the uplink transmission data amount is greater than or equal to the data amount threshold.

In actual application, if the uplink transmission data volume is smaller than a data volume threshold, carrier scheduling suggestion information is generated; the carrier scheduling suggestion information comprises suggestion selection uplink carrier bearing uplink transmission and suggestion reasons.

The carrier types selected by the network side are suggested as follows: and (4) uplink carrier waves. The reason for the suggestion is that: the uplink transmission data volume is less than the data volume threshold.

It should be noted that, in order to save signaling overhead, the terminal may generate carrier scheduling suggestion information when it is determined that the SUL carrier needs to be used for uplink transmission, and send the generated carrier scheduling suggestion information to the network device. In other words, if the uplink transmission data amount is smaller than the data amount threshold, the terminal may not send carrier scheduling suggestion information to the network device, thereby reducing signaling overhead.

Here, the estimating of the uplink transmission power corresponding to the current service includes:

Here, the uplink transmission power corresponding to the current service may be estimated according to formula (1).

P＝{P₀(j)+α(k)·PL(q)}+{ΔPL} (1)

Wherein, { P₀(j) + α (k) · pl (q) } is that when the terminal needs to initiate a certain service application, it enters RRC connection state, and the terminal obtains the open-loop control parameters of uplink power control from RRC signaling, such as open-loop received power target value, path loss estimation, configuration parameters of part of path loss compensation factors, etc.; { Δ PL } is the path loss estimate.

In an example, taking a 5G system as an example, as shown in fig. 5, a process that a terminal generates carrier scheduling suggestion information and sends the carrier scheduling suggestion information to a network device is described, including:

step 501: the terminal judges whether the current service requires low-delay transmission; when it is determined that the current service does not require low latency transmission, perform step 502;

step 502: the terminal measures the signal quality of the uplink carrier;

step 503: judging whether the signal quality of the uplink carrier is greater than a signal quality threshold value; when the signal quality of the uplink carrier is greater than the signal quality threshold, executing step 504;

step 504: the terminal estimates the uplink transmission power corresponding to the current service; judging whether the uplink transmission power is smaller than the maximum transmission power, and executing step 505 when the uplink transmission power is smaller than the maximum transmission power;

step 505: judging whether the uplink transmission data volume corresponding to the current service is greater than or equal to a data volume threshold value; if the uplink transmission data amount is greater than or equal to the data amount threshold, execute step 506;

here, when the estimated uplink transmission power P and the terminal maximum transmission power P are_CMAXIs less than or equal to P_THThen, the terminal determines that the estimated uplink transmission power is equal to the maximum transmitting power; otherwise, the terminal determines that the estimated uplink transmission power is smaller than the maximum transmission power. The maximum value of the power adjustment amount can be determined according to resource allocation and MCS values. The terminal can sum the adjustment step length of the closed-loop power control and the maximum value of the power adjustment quantity to obtain a power threshold value P_TH。

Here, the data amount threshold may be determined according to an uplink transmission data amount that can be provided by the uplink carrier, for example, assuming that the uplink transmission data amount that can be provided by the uplink carrier is denoted by M, the data amount threshold may be equal to M × N%, where M and N are positive integers. Or, the data amount threshold may also be determined according to an average value of uplink transmission resources corresponding to NR carriers scheduled by the network side for the terminal within a period of time.

Step 506: the terminal generates carrier scheduling suggestion information; the carrier scheduling suggestion information comprises suggestion selection of an SUL carrier and an NR carrier to jointly carry uplink transmission and suggestion reasons.

Here, the carrier types proposed for selection by the network side are: SUL and NR carriers; the reason for the suggestion is that: the uplink transmission data amount is greater than or equal to the data amount threshold.

Here, since the terminal can perform uplink transmission only by using an uplink carrier of one of the SUL carrier and the NR carrier at the same time, the terminal may perform uplink transmission in an uplink slot of the NR carrier, or the terminal may perform uplink transmission using an uplink slot of the SUL carrier when the NR carrier is in a downlink slot.

Step 507: and the terminal sends the generated carrier scheduling suggestion information to the network equipment.

Here, the terminal generates the carrier scheduling suggestion information based on the transmission delay of the current service, the signal quality of the uplink carrier, and the uplink transmission data amount, and has the following advantages:

in the central area or the area close to the center of the cell, the NR carrier and the SUL carrier are combined, and the uplink transmission resource can be increased, thereby increasing the uplink data transmission rate, so that when the terminal determines that the current service does not require low-delay transmission, and the signal quality of the NR carrier is greater than the signal quality threshold, the uplink transmission power is less than the maximum transmission power, and the uplink transmission data amount is greater than or equal to the threshold, the network side is recommended to select the SUL carrier and the NR carrier to jointly carry uplink transmission, and the uplink transmission rate can be effectively increased.

In an example, taking a 5G system as an example, as shown in fig. 6, a process that a terminal sends carrier scheduling suggestion information to a network device is described, where the process includes:

step 601: the terminal judges whether the current service requires low-delay transmission; when it is determined that the current service does not require low-latency transmission, perform step 602;

step 602: the terminal measures the signal quality of the uplink carrier;

step 603: judging whether the signal quality of the uplink carrier is greater than a signal quality threshold value; when the signal quality of the uplink carrier is greater than the signal quality threshold, executing step 604;

step 604: the terminal estimates the uplink transmission power corresponding to the current service; judging whether the uplink transmission power is smaller than the maximum transmission power, and executing a step 605 when the uplink transmission power is smaller than the maximum transmission power;

step 605: judging whether the uplink transmission data volume corresponding to the current service is greater than or equal to a data volume threshold value; if the uplink transmission data volume is smaller than the data volume threshold, executing step 606;

step 606: the terminal generates carrier scheduling suggestion information; the carrier scheduling suggestion information comprises suggestion selection NR carrier carrying uplink transmission and suggestion reasons.

Here, the carrier types proposed for selection by the network side are: an NR carrier; the reason for the suggestion is that: the uplink transmission data volume is less than the data volume threshold.

Step 607: and the terminal sends the generated carrier scheduling suggestion information to the network equipment.

Here, the network device may determine an uplink carrier scheduling manner for the terminal according to carrier scheduling suggestion information sent by the terminal, and by combining factors such as channel quality, signal strength, load condition, and network scheduling complexity of an NR carrier and a SUL carrier that is a supplementary carrier of the NR carrier. The NR carrier may provide more uplink transmission resources and transmission rates than the SUL carrier, and the network device schedules the NR carrier to carry uplink transmission with higher priority than the SUL carrier.

It should be noted that step 606 and step 607 may not be performed in order to save signaling overhead.

the NR carriers can provide more uplink transmission resources and transmission rates than the SUL carriers are fully considered, so when the terminal judges that the current service does not require low-delay transmission, the signal quality of the NR carriers is greater than a signal quality threshold, the uplink transmission power is less than the maximum transmission power, and the uplink transmission data volume is less than a data volume threshold, the network side is recommended to schedule the NR carriers preferentially, and the waste of the SUL carrier resources can be avoided.

In practical application, if the signal quality of the uplink carrier is high, the terminal may recommend the network side to select the carrier type for carrying the uplink transmission in combination with the uplink transmission power and the uplink transmission data amount. The terminal can estimate the uplink transmission power corresponding to the current service by combining the acquired open-loop control parameters, the current moving speed of the terminal and the like, if the estimated uplink transmission power reaches the maximum transmitting power configured by the network side, namely the influence of radiation generated by the terminal on the user is large, under the condition, in order to meet SAR indexes and reduce the influence of the radiation generated by the terminal on the user, if the uplink transmission data volume corresponding to the current service is large, the network side can be recommended to select an uplink carrier and a supplementary carrier of the uplink carrier, namely an SUL carrier, to jointly carry uplink transmission; in consideration of the fact that the radiation generated by the terminal increases if all of the plurality of uplink timeslots corresponding to the SUL carrier are used, the terminal may notify the network side of the uplink timeslot proportion of the SUL carrier.

estimating uplink transmission power corresponding to the current service;

The uplink timeslot proportion corresponding to the SUL carrier represents the number of uplink timeslots capable of carrying uplink transmission in the plurality of uplink timeslots corresponding to the SUL carrier.

Here, when the uplink transmission power estimated by the terminal is equal to the maximum transmission power, in order to satisfy the SAR indicator, the terminal uses a dual transmission/reception, i.e., a 2Tx mode, on the NR carrier and a single transmission/reception, i.e., a 1Tx mode, on the SUL carrier, i.e., the maximum transmission power averaged by the terminal in each radio frame time does not exceed 23 dBm. The terminal may determine the uplink timeslot proportion of the SUL carrier according to the uplink timeslot configuration of the NR carrier.

For example, taking the NR carrier uplink and downlink timeslot ratio DL: S: UL: 7:1:2 as an example, the uplink timeslot of the NR carrier is configured to be 20%, and the uplink timeslot of the SUL carrier needs to be reduced by 20% as well, that is, the uplink timeslot proportion of the SUL carrier is 60%.

In an example, taking a 5G system as an example, as shown in fig. 7, a process that a terminal sends carrier scheduling suggestion information to a network device is described, where the process includes:

step 701: the terminal judges whether the current service requires low-delay transmission; when it is determined that the current service does not require low latency transmission, perform step 702;

step 702: the terminal measures the signal quality of the uplink carrier;

step 703: judging whether the signal quality of the uplink carrier is greater than a signal quality threshold value; when the signal quality of the uplink carrier is greater than the signal quality threshold, executing step 704;

in the 5G system, the uplink carrier may refer to an NR carrier. The Signal quality of the NR carrier can be obtained by measuring Reference Signal Received Power (RSRP) of the NR carrier, and the like.

Step 704: the terminal estimates the uplink transmission power corresponding to the current service; judging whether the uplink transmission power is smaller than the maximum transmission power; when the uplink transmission power is equal to the maximum transmission power, executing step 705;

step 705: judging whether the uplink transmission data volume corresponding to the currently executed service is greater than or equal to a data volume threshold value; if the uplink transmission data amount is greater than or equal to the data amount threshold, execute step 706;

step 706: the terminal generates carrier scheduling suggestion information; the carrier scheduling suggestion information comprises the SUL carrier which is selected by suggestion and commonly carries uplink transmission with the uplink carrier, the uplink time slot ratio corresponding to the SUL carrier and the carrier scheduling suggestion information generated by the suggestion reason terminal.

Step 707: and the terminal sends the generated carrier scheduling suggestion information to the network equipment.

when the terminal judges that the uplink transmission power is equal to the maximum transmitting power, the uplink time slot of the SUL carrier can be correspondingly reduced according to the uplink time slot configuration of the NR carrier in combination with the uplink transmission requirement of the terminal, so that the terminal can meet the requirement of the SAR index.

And 4, the terminal generates carrier scheduling suggestion information based on the transmission delay requirement of the current service, the signal quality of the uplink carrier, the uplink transmission power, the uplink transmission data volume and the electric quantity of the terminal.

In practical application, if the signal quality of the uplink carrier is high, the terminal may recommend the network side to select the carrier type for carrying the uplink transmission in combination with the uplink transmission power and the uplink transmission data amount. The terminal can estimate the uplink transmission power corresponding to the current service by combining the acquired open-loop control parameters, the current moving speed of the terminal and the like, if the estimated uplink transmission power reaches the maximum transmitting power configured at the network side, namely the influence of radiation generated by the terminal on the user is large, under the condition, in order to meet SAR indexes and reduce the influence of the radiation generated by the terminal on the user, if the uplink transmission data volume corresponding to the current service is small and the current electric quantity of the terminal is low, the network side can be recommended to select a supplementary carrier of an uplink carrier, namely an SUL carrier, to carry uplink transmission; if the uplink transmission data volume corresponding to the current service is small and the current electric quantity of the terminal is high, the network side can be recommended to select the uplink carrier to carry the uplink transmission.

The generating carrier scheduling suggestion information based on the uplink transmission power and the uplink transmission data amount corresponding to the current service includes:

estimating uplink transmission power corresponding to the current service;

when the comparison result represents that the uplink transmission power is equal to the maximum transmission power, judging whether the data volume of uplink transmission corresponding to the current service is smaller than a data volume threshold value or not;

Here, when the remaining power of the terminal is greater than or equal to the power threshold, carrier scheduling suggestion information is generated; the carrier scheduling suggestion information comprises suggestion selection uplink carrier bearing uplink transmission and suggestion reasons.

It should be noted that, in order to save signaling overhead, the terminal may generate carrier scheduling suggestion information when it is determined that the SUL carrier needs to be used for uplink transmission, and send the generated carrier scheduling suggestion information to the network device. In other words, when the remaining power of the terminal is greater than or equal to the power threshold, the terminal may not generate the carrier scheduling suggestion information and may not transmit the carrier scheduling suggestion information to the network device, thereby reducing signaling overhead.

In an example, taking a 5G system as an example, as shown in fig. 8, a process that a terminal sends carrier scheduling suggestion information to a network device is described, where the process includes:

step 801: the terminal judges whether the current service requires low-delay transmission; when it is determined that the current service does not require low-latency transmission, performing step 802;

step 802: the terminal measures the signal quality of the uplink carrier;

step 803: judging whether the signal quality of the uplink carrier is greater than a signal quality threshold value; when the signal quality of the uplink carrier is greater than the signal quality threshold, executing step 804;

in the 5G system, the uplink carrier may refer to an NR carrier. The signal quality of the NR carrier can be obtained by measuring RSRP of the NR carrier.

Step 804: the terminal estimates the uplink transmission power corresponding to the current service; judging whether the uplink elaboration power is equal to the maximum transmitting power; when the uplink transmission power is equal to the maximum transmission power, executing step 805;

step 805: judging that the uplink transmission data volume corresponding to the currently executed service is smaller than a data volume threshold; if the uplink transmission data amount is smaller than the data amount threshold, execute step 806;

step 806: acquiring the residual electric quantity of the terminal; judging whether the residual electric quantity of the terminal is less than the electric quantity budget or not; when the remaining power of the terminal is less than the power threshold, go to step 807;

step 807: the terminal generates carrier scheduling suggestion information;

the carrier scheduling suggestion information comprises suggestion selection SUL carrier bearing uplink transmission and suggestion reasons.

Step 808: and the terminal sends the generated carrier scheduling suggestion information to the network equipment.

Here, the terminal generates the carrier scheduling suggestion information based on the transmission delay requirement of the current service, the signal quality of the uplink carrier, the uplink transmission power, the uplink transmission data volume, and the electric quantity of the terminal, and has the following advantages:

the terminal forms a scheduling proposal scheme of the SUL carrier based on information such as transmission delay requirement of current service, signal quality of uplink carrier, uplink transmitting power, uplink transmission data volume, electric quantity of the terminal and the like, can provide an uplink enhancement scheme aiming at the terminal by combining uplink transmission requirement of a user and electric quantity state of the terminal, and simultaneously meets the requirement of SAR index.

In an example, taking a 5G system as an example, as shown in fig. 9, a process that a terminal sends carrier scheduling suggestion information to a network device is described, where the process includes:

step 901: the terminal judges whether the current service requires low-delay transmission; when it is determined that the current service does not require low-latency transmission, perform step 902;

step 902: the terminal measures the signal quality of the uplink carrier;

step 903: judging whether the signal quality of the uplink carrier is greater than a signal quality threshold value; when the signal quality of the uplink carrier is greater than the signal quality threshold, executing step 904;

Step 904: the terminal estimates the uplink transmission power corresponding to the current service; judging whether the uplink elaboration power is equal to the maximum transmitting power; when the uplink transmission power is equal to the maximum transmission power, executing step 905;

step 905: judging that the uplink transmission data volume corresponding to the currently executed service is smaller than a data volume threshold; if the uplink transmission data volume is smaller than the data volume threshold, execute step 906;

step 906: acquiring the residual electric quantity of the terminal; judging whether the residual electric quantity of the terminal is greater than or equal to the electric quantity budget or not; when the remaining power of the terminal is greater than or equal to the power threshold, step 907 is executed;

step 907: the terminal does not transmit carrier scheduling suggestion information to the network device.

Here, when the uplink transmission data amount is smaller than the data amount threshold, the terminal does not transmit the carrier scheduling suggestion information to the network device, and the following advantages are provided:

when the terminal determines that uplink transmission does not need to be performed by using the SUL carrier but an NR carrier needs to be used, carrier scheduling suggestion information may not be sent to the network device in order to save signaling overhead.

It should be noted that, in the embodiment of the present invention, taking 5G as an example, the functions of enhancing the uplink coverage of the NR cell, increasing the uplink data transmission rate, and shortening the transmission delay can be achieved by flexibly configuring and scheduling the SUL carrier, and meanwhile, a targeted uplink enhancement scheme is provided by using the SUL carrier in combination with the uplink transmission requirement of the user, the power state of the terminal, and the like, so that the transmission requirement of the user can be met, and the waste of transmission resources is not caused.
