[0064] Before introducing the technical solution of the embodiment of the present invention, the related technology is first described.

[0065] In the fifth generation (5G) mobile communication system, in order to improve the uplink coverage and uplink data transmission rate, multiple uplink carriers can be configured in a cell through uplink enhancement technology, namely uplink and downlink decoupling technology. The carrier used for supplementary uplink transmission among multiple uplink carriers is called SUL carrier. Usually, the configuration and scheduling of SUL carrier and New Radio (NR) carrier are implemented by the network side. On the one hand, if the network side performs targeted configuration and scheduling for the status of each user in the cell, it will increase the processing overhead and complexity of the network side; on the other hand, if the network side adopts a unified carrier configuration and scheduling scheme for the cell, it will not be able to meet the transmission needs of terminal users in a targeted manner, affect the user experience, and also cause a waste of network resources.

[0066] Based on this, in various embodiments of the present invention, carrier scheduling recommendation information is generated; the generated carrier scheduling recommendation information is sent to a network device; the carrier scheduling recommendation information is used by the network device to make scheduling decisions on the carrier that carries uplink transmission.

[0067] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0068] The embodiment of the present invention provides an information transmission method, such as Figure 1 As shown, the method includes:

[0069] Step 101: Generate carrier scheduling suggestion information;

[0070] Step 102: Send the generated carrier scheduling recommendation information to the network device; the carrier scheduling recommendation information is used by the network device to make scheduling decisions on the carrier that carries uplink transmission.

[0071] Here, in step 101, when at least two uplink carriers are configured for the terminal through uplink enhancement technology, the terminal can generate carrier scheduling recommendation information. For example, in a 5G system, when an NR carrier and a SUL carrier are configured for the terminal through uplink enhancement technology, the terminal can generate carrier scheduling recommendation information.

[0072] Here, in step 102, the generated carrier scheduling recommendation information may be sent to the network device via a first signaling. The first signaling may specifically be a radio resource control (RRC, Radio Resource Control) signaling.

[0073] In actual application, when the terminal performs uplink transmission with the network side, the factors that the terminal may consider when considering how to recommend the network side to select a carrier for carrying the uplink transmission 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 amount of uplink transmission data corresponding to the service, the power of the terminal, etc.

[0074] Based on this, in one embodiment, generating carrier scheduling suggestion information includes:

[0075] The carrier scheduling suggestion information is generated based on at least one of 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.

[0076] The following describes in detail how the terminal generates carrier scheduling recommendation information according to different situations.

[0077] In case 1, the terminal generates carrier scheduling recommendation information based on the transmission delay requirement of the current service.

[0078] In actual application, when the service type transmitted between the terminal and the network side is live broadcast or other services, since the service needs to meet low-latency transmission, the terminal can suggest the network side to select a carrier from at least two uplink carriers that can shorten the service transmission delay.

[0079] Based on this, in one embodiment, the generating of carrier scheduling suggestion information based on at least one of 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 includes:

[0080] Determine whether the current service requires low-latency transmission;

[0081] When it is determined that the current service requires low-latency transmission, carrier scheduling recommendation information is generated; the carrier scheduling recommendation information includes a recommendation to select a SUL carrier to carry uplink transmission and a reason for the recommendation.

[0082] Among them, the carrier type recommended to be selected by the network side is: SUL carrier; the reason for the recommendation is: the current service requires low-latency transmission.

[0083] Here, since the SUL carrier adopts the frequency division duplex (FDD) working mode, that is, the uplink and downlink use two separate frequencies to work, if the SUL carrier is used to carry uplink transmission, services can be transmitted simultaneously on multiple uplink time slots corresponding to the SUL carrier, thereby shortening the service transmission delay.

[0084] In actual application, the methods for determining whether the current service requires low-latency transmission include one of the following:

[0085] Matching the current service with the preset type to obtain a matching result; if the matching result indicates that the current service matches the preset type, determining that the current service requires low-latency transmission;

[0086] Determine a first QoS corresponding to the current service according to a correspondence between the service and the quality of service (QoS) configured on the network side; when the first QoS meets a preset condition, determine that the current service requires low-latency transmission;

[0087] According to the correspondence between the services configured on the network side and the network slices, the first network slice corresponding to the current service is determined; when the first network slice requires low-latency transmission of the service, it is determined that the current service requires low-latency transmission.

[0088] For example, assuming that the preset type is a live broadcast service type, if the current service is a browsing service, since the current service type does not match the preset type, it is determined that the current service does not require low-latency transmission. Alternatively, based on the correspondence between the service and QoS configured on the network side, the first QoS corresponding to the current service is determined. Assuming that the value of the first QoS is 10, and the value of the first QoS is greater than the preset threshold, it is determined that the current service requires low-latency transmission; otherwise, it is determined that the current service does not require low-latency transmission. Alternatively, based on the correspondence between the service and the network slice configured on the network side, the first network slice corresponding to the current service is determined. If the first network slice requires a low-latency transmission service, it is determined that the current service requires low-latency transmission; wherein, the first network slice may refer to a network resource among multiple network resources obtained by dividing network resources.

[0089] In one example, taking a 5G system as an example, Figure 2 As shown, the process of generating carrier scheduling suggestion information by the terminal and sending it to the network device is described, including:

[0090] Step 201: The terminal determines whether the current service requires low-latency transmission; when it is determined that the current service requires low-latency transmission, step 202 is executed:

[0091] Here, when the terminal starts an application for uplink / downlink data transmission, it determines whether the current service requires low-latency transmission. If the service executed by the opened application is a service under the Ultra-Reliable and Low Latency Communications (URLLC) scenario, the terminal determines that the current service requires low-latency transmission.

[0092] Step 202: The terminal generates carrier scheduling recommendation information; the carrier scheduling recommendation information includes a recommendation to select a SUL carrier to bear uplink transmission and a reason for the recommendation.

[0093] Among them, the carrier type recommended for the network side is: SUL carrier, and the reason for the recommendation is: the current service requires low-latency transmission.

[0094] Step 203: The terminal sends the generated carrier scheduling recommendation information to the network device.

[0095] Here, the network device can determine the uplink carrier scheduling method for the terminal based on the carrier scheduling recommendation information sent by the terminal, and combined with the channel quality, signal strength, load conditions, network scheduling complexity and other factors of the uplink carrier, i.e., the NR carrier, and the supplementary uplink carrier, i.e., the SUL carrier of the uplink carrier.

[0096] It should be noted that compared with the SUL carrier, the NR carrier can provide more uplink transmission resources and transmission rates, and the network equipment schedules the NR carrier to carry uplink transmission with a higher priority than the SUL carrier.

[0097] Figure 3 is a schematic diagram of a SUL carrier, such as Figure 3 As shown, the frequency of the SUL carrier is lower than that of the NR carrier, for example, the NR carrier is 2.6 GHz and the SUL carrier is 1.8 GHz.

[0098] Here, the terminal generates carrier scheduling suggestion information based on the transmission delay of the current service of the terminal, which has the following advantages:

[0099] Since the SUL carrier adopts the working mode of the FDD frequency band, that is, the SUL carrier realizes continuous uplink transmission in the corresponding multiple uplink time slots, that is, the services can be transmitted simultaneously in the multiple uplink time slots corresponding to the SUL carrier, and the NR carrier adopts the working mode of the TDD frequency band, that is, the services cannot be transmitted simultaneously in the multiple uplink time slots corresponding to the NR carrier. Therefore, when the terminal determines that the current service requires low-latency transmission, it is recommended that the network side select the SUL carrier to carry the uplink transmission, which can complete the feedback of downlink data and uplink data transmission in the shortest time, thereby shortening the latency.

[0100] In case 2, the terminal generates carrier scheduling recommendation information based on the transmission delay requirement of the current service and the signal quality of the uplink carrier.

[0101] In actual application, when the service transmitted between the terminal and the network side is a browsing service, since the service does not require low-latency transmission, if the signal quality of the uplink carrier is low, it can be recommended that the network side select the supplementary carrier of the uplink carrier, namely the SUL carrier, to carry the uplink transmission.

[0102] Based on this, in one embodiment, the generating of carrier scheduling suggestion information based on at least one of 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 includes:

[0103] Determine whether the current service requires low-latency transmission;

[0104] When it is determined that the current service does not require low-latency transmission, measuring the signal quality of the uplink carrier;

[0105] If the signal quality of the uplink carrier is less than or equal to the signal quality threshold, carrier scheduling recommendation information is generated; the carrier scheduling recommendation information includes a recommendation to select a SUL carrier to bear uplink transmission and a reason for the recommendation.

[0106] Here, it is recommended that the carrier type selected by the network side is: SUL carrier; the reason for the recommendation is: the signal quality of the uplink carrier is less than or equal to the signal quality threshold.

[0107] In one example, taking a 5G system as an example, Figure 4 As shown, the process of generating carrier scheduling suggestion information by the terminal and sending it to the network device is described, including:

[0108] Step 401: The terminal determines whether the current service requires low-latency transmission; when it is determined that the current service does not require low-latency transmission, step 402 is executed;

[0109] Step 402: The terminal measures the signal quality of the uplink carrier;

[0110] Step 403: The terminal determines whether the signal quality of the uplink carrier is less than or equal to the signal quality threshold; when the signal quality of the uplink carrier is less than or equal to the signal quality threshold, execute step 404;

[0111] 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.

[0112] Step 404: The terminal generates carrier scheduling recommendation information; the carrier scheduling recommendation information includes a recommendation to select a SUL carrier to bear uplink transmission and a reason for the recommendation.

[0113] Among them, the carrier type recommended to be selected by the network side is: SUL carrier; the reason for the recommendation is: the signal quality of the uplink carrier is lower than the signal quality threshold.

[0114] Step 405: The terminal sends the generated carrier scheduling recommendation information to the network device.

[0115] Here, the network device can determine the uplink carrier scheduling method for the terminal based on the carrier scheduling recommendation information sent by the terminal, and combined with the channel quality, signal strength, load condition, network scheduling complexity and other factors of the uplink carrier, i.e., the NR carrier, and the supplementary carrier of the uplink carrier, i.e., the SUL carrier.

[0116] It should be noted that compared with the SUL carrier, the NR carrier can provide more uplink transmission resources and transmission rates, and the network equipment schedules the NR carrier to carry uplink transmission with a higher priority than the SUL carrier.

[0117] Here, the terminal generates carrier scheduling suggestion information based on the transmission delay of the current service and the signal quality of the uplink carrier, which has the following advantages:

[0118] Since 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-latency transmission and the signal quality of the NR carrier is lower than the signal quality threshold, it is recommended that the network side select the SUL carrier to carry the uplink transmission, which can effectively increase the edge rate of the uplink transmission and improve the uplink transmission performance of edge users.

[0119] In actual applications, when the service transmitted between the terminal and the network side is a browsing service, since this service does not require low-latency transmission, if the signal quality of the uplink carrier is high, the uplink transmission power and the uplink transmission data volume can be combined. It is recommended that the network side select the carrier type that carries the uplink transmission.

[0120] Based on this, in one embodiment, the generating of carrier scheduling suggestion information based on at least one of 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 includes:

[0121] Determine whether the current service requires low-latency transmission;

[0122] When it is determined that the current service does not require low-latency transmission, measuring the signal quality of the uplink carrier;

[0123] If the signal quality of the uplink carrier is greater than the signal quality threshold, carrier scheduling recommendation information is generated based on the uplink transmission power and uplink transmission data volume corresponding to the current service.

[0124] In case 3, when the uplink transmission power is less than the maximum transmission power configured on the network side, the terminal generates carrier scheduling recommendation 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.

[0125] In actual application, if the signal quality of the uplink carrier is high, the terminal can combine the uplink transmission power and the uplink transmission data volume to recommend the network side to select the carrier type that carries the uplink transmission. The terminal can estimate the uplink transmission power corresponding to the current service based on the acquired open-loop control parameters, the current mobile speed of the terminal, etc. If the estimated uplink transmission power does not reach the maximum transmission power configured by the network side, that is, the radiation generated by the terminal has a low impact on the user, in this case, if the uplink transmission data volume corresponding to the current service is large, it can be recommended that the network side select the uplink carrier and the supplementary carrier of the uplink carrier, that is, the SUL carrier, to jointly carry the uplink transmission; if the uplink transmission data volume corresponding to the current service is small, it can be recommended that the network side give priority to the uplink carrier to carry the uplink transmission.

[0126] Based on this, in one embodiment, the generating of carrier scheduling suggestion information based on the uplink transmission power and uplink transmission data volume corresponding to the current service includes:

[0127] Estimate the uplink transmission power corresponding to the current service;

[0128] Comparing the uplink transmission power with the maximum transmission power configured on the network side to obtain a comparison result;

[0129] When the comparison result indicates that the uplink transmission power is less than the maximum transmission power, determining whether the uplink transmission data volume corresponding to the currently executed service is greater than or equal to a data volume threshold;

[0130] If the uplink transmission data volume is greater than or equal to the data volume threshold, carrier scheduling recommendation information is generated; the carrier scheduling recommendation information includes a recommendation to select the SUL carrier and the uplink carrier to jointly carry the uplink transmission and a reason for the recommendation.

[0131] The carrier types recommended for the network side to select are: SUL carrier and uplink carrier. The reason for the recommendation is: the uplink transmission data volume is greater than or equal to the data volume threshold.

[0132] In actual application, if the uplink transmission data volume is less than the data volume threshold, carrier scheduling recommendation information is generated; the carrier scheduling recommendation information includes a recommendation to select an uplink carrier to carry uplink transmission and a reason for the recommendation.

[0133] The carrier type recommended for the network side is: uplink carrier. The reason for the recommendation is: the uplink transmission data volume is less than the data volume threshold.

[0134] It should be noted that, in order to save signaling overhead, the terminal may generate carrier scheduling recommendation information when determining that the SUL carrier needs to be used for uplink transmission, and send the generated carrier scheduling recommendation information to the network device. In other words, if the uplink transmission data volume is less than the data volume threshold, the terminal may not send the carrier scheduling recommendation information to the network device, thereby reducing signaling overhead.

[0135] Here, estimating the uplink transmission power corresponding to the current service includes:

[0136] Obtaining an open-loop control parameter for controlling uplink transmission power;

[0137] Determine a path loss estimate value according to a current moving speed of the terminal and a time interval between a first moment when the terminal obtains an open-loop power control parameter and a second moment when uplink transmission is expected;

[0138] The uplink transmission power corresponding to the current service is estimated according to the open-loop control parameter and the estimated path loss value.

[0139] Here, the uplink transmission power corresponding to the current service can be estimated according to formula (1).

[0140] P={P0(j)+α(k)·PL(q)}+{ΔPL} (1)

[0141] Among them, {P0(j)+α(k)·PL(q)} is when the terminal enters the RRC connected state when it needs to initiate a service application, the terminal obtains the open-loop control parameters of the uplink power control from the RRC signaling, such as the open-loop receiving power target value, path loss estimation, partial path loss compensation factor and other configuration parameters; {ΔPL} is the path loss estimation value.

[0142] In one example, taking a 5G system as an example, Figure 5 As shown, the process of generating carrier scheduling suggestion information by the terminal and sending it to the network device is described, including:

[0143] Step 501: The terminal determines whether the current service requires low-latency transmission; when it is determined that the current service does not require low-latency transmission, step 502 is executed;

[0144] Step 502: The terminal measures the signal quality of the uplink carrier;

[0145] Step 503: determine whether the signal quality of the uplink carrier is greater than the signal quality threshold; when the signal quality of the uplink carrier is greater than the signal quality threshold, execute step 504;

[0146] Step 504: the terminal estimates the uplink transmission power corresponding to the current service; determines whether the uplink transmission power is less than the maximum transmission power, and when the uplink transmission power is less than the maximum transmission power, executes step 505;

[0147] Step 505: Determine whether the uplink transmission data volume corresponding to the current service is greater than or equal to the data volume threshold; if the uplink transmission data volume is greater than or equal to the data volume threshold, execute step 506;

[0148] Here, when the estimated uplink transmission power P is equal to the maximum terminal transmission power P CMAX The difference is less than or equal to P TH When the estimated uplink transmission power is equal to the maximum transmission power, the terminal determines that the estimated uplink transmission power is equal to the maximum transmission power; otherwise, the terminal determines that the estimated uplink transmission power is less than the maximum transmission power. The maximum value of the power adjustment amount can be determined according to the resource allocation and the value of the MCS. The terminal can sum the closed-loop power control adjustment step size and the maximum value of the power adjustment amount to obtain the power threshold value P TH .

[0149] Here, the data volume threshold may be determined according to the amount of uplink transmission data that can be provided by the uplink carrier. For example, assuming that the amount of uplink transmission data that can be provided by the uplink carrier is represented by M, the data volume threshold may be equal to M×N%, where M and N are positive integers. Alternatively, the data volume threshold may also be determined according to an average value of uplink transmission resources corresponding to the NR carrier scheduled by the network side for the terminal over a period of time.

[0150] Step 506: The terminal generates carrier scheduling recommendation information; the carrier scheduling recommendation information includes a recommendation to select the SUL carrier and the NR carrier to jointly carry uplink transmission and a reason for the recommendation.

[0151] Here, it is recommended that the carrier types selected by the network side are: SUL carrier and NR carrier; the reason for the recommendation is: the amount of uplink transmission data is greater than or equal to the data amount threshold.

[0152] Here, since the terminal can only use the uplink carrier of one of the SUL carrier and the NR carrier for uplink transmission at the same time, the terminal can perform uplink transmission in the uplink time slot of the NR carrier, or the terminal can use the uplink time slot of the SUL carrier for uplink transmission when the NR carrier is in the downlink time slot.

[0153] Step 507: The terminal sends the generated carrier scheduling recommendation information to the network device.

[0154] Here, the network device can determine the uplink carrier scheduling method for the terminal based on the carrier scheduling recommendation information sent by the terminal, and combined with the channel quality, signal strength, load conditions, network scheduling complexity and other factors of the uplink carrier, i.e., the NR carrier, and the supplementary uplink carrier, i.e., the SUL carrier of the uplink carrier.

[0155] It should be noted that compared with the SUL carrier, the NR carrier can provide more uplink transmission resources and transmission rates, and the network equipment schedules the NR carrier to carry uplink transmission with a higher priority than the SUL carrier.

[0156] Here, the terminal generates 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 volume, which has the following advantages:

[0157] In the central area or near the center of the cell, the combination of NR carrier and SUL carrier can increase uplink transmission resources, thereby improving the uplink data transmission rate. Therefore, when the terminal determines that the current service does not require low-latency 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 volume is greater than or equal to the threshold, it is recommended that the network side select SUL carrier and NR carrier to jointly carry uplink transmission, which can effectively improve the uplink transmission rate.

[0158] In one example, taking a 5G system as an example, Figure 6 As shown, the process of sending carrier scheduling suggestion information from the terminal to the network device is described, including:

[0159] Step 601: The terminal determines whether the current service requires low-latency transmission; when it is determined that the current service does not require low-latency transmission, step 602 is executed;

[0160] Step 602: The terminal measures the signal quality of the uplink carrier;

[0161] Step 603: Determine whether the signal quality of the uplink carrier is greater than the signal quality threshold; when the signal quality of the uplink carrier is greater than the signal quality threshold, execute step 604;

[0162] Step 604: the terminal estimates the uplink transmission power corresponding to the current service; determines whether the uplink transmission power is less than the maximum transmission power, and when the uplink transmission power is less than the maximum transmission power, executes step 605;

[0163] Step 605: Determine whether the uplink transmission data volume corresponding to the current service is greater than or equal to the data volume threshold; if the uplink transmission data volume is less than the data volume threshold, execute step 606;

[0164] Step 606: The terminal generates carrier scheduling recommendation information; the carrier scheduling recommendation information includes a recommendation to select an NR carrier to carry uplink transmission and a reason for the recommendation.

[0165] Here, it is recommended that the carrier type selected by the network side is: NR carrier; the reason for the recommendation is: the amount of uplink transmission data is less than the data amount threshold.

[0166] Step 607: The terminal sends the generated carrier scheduling recommendation information to the network device.

[0167] Here, the network device can determine the uplink carrier scheduling method for the terminal based on the carrier scheduling recommendation information sent by the terminal, and combined with the channel quality, signal strength, load condition, network scheduling complexity and other factors of the uplink carrier, i.e., the NR carrier, and the supplementary carrier of the uplink carrier, i.e., the SUL carrier. Among them, compared with the SUL carrier, the NR carrier can provide more uplink transmission resources and transmission rates, and the network device schedules the NR carrier to carry uplink transmission with a higher priority than the SUL carrier.

[0168] It should be noted that, in order to save signaling overhead, step 606 and step 607 may not be performed.

[0169] Here, the terminal generates 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 volume, which has the following advantages:

[0170] Taking into full consideration that the NR carrier can provide more uplink transmission resources and transmission rates than the SUL carrier, when the terminal determines that the current service does not require low-latency 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 volume is less than the data volume threshold, it is recommended that the network side give priority to scheduling the NR carrier to avoid wasting SUL carrier resources.

[0171] In actual application, if the signal quality of the uplink carrier is high, the terminal can combine the uplink transmission power and the amount of uplink transmission data, and recommend the network side to select the type of carrier that carries the uplink transmission. The terminal can estimate the uplink transmission power corresponding to the current service based on the acquired open-loop control parameters, the current moving speed of the terminal, etc. If the estimated uplink transmission power reaches the maximum transmission power configured on the network side, that is, the radiation generated by the terminal has a greater impact on the user, in this case, in order to meet the SAR index and reduce the impact of the radiation generated by the terminal on the user, if the amount of uplink transmission data corresponding to the current service is large, it can be recommended that the network side select the uplink carrier and the supplementary carrier of the uplink carrier, that is, the SUL carrier, to jointly carry the uplink transmission; considering that if multiple uplink time slots corresponding to the SUL carrier are all used, it will cause the radiation generated by the terminal to increase, therefore, the terminal can notify the network side of the uplink time slot ratio of the SUL carrier.

[0172] Based on this, in one embodiment, the generating of carrier scheduling suggestion information based on the uplink transmission power and uplink transmission data volume corresponding to the current service includes:

[0173] Estimate the uplink transmission power corresponding to the current service;

[0174] Comparing the uplink transmission power with the maximum transmission power configured on the network side to obtain a comparison result;

[0175] When the comparison result indicates that the uplink transmission power is equal to the maximum transmission power, determining whether the amount of uplink transmission data corresponding to the current service is greater than or equal to a data amount threshold;

[0176] If the uplink transmission data volume is greater than or equal to the data volume threshold, carrier scheduling recommendation information is generated; the carrier scheduling recommendation information includes a recommendation to select the SUL carrier and the uplink carrier to jointly carry the uplink transmission, the uplink time slot ratio corresponding to the SUL carrier, and the reason for the recommendation.

[0177] The uplink time slot ratio corresponding to the SUL carrier represents the number of uplink time slots that can be used to carry uplink transmission among the multiple uplink time slots corresponding to the SUL carrier.

[0178] Here, when the estimated uplink transmission power of the terminal is equal to the maximum transmission power, considering that the terminal adopts dual-transmission and reception, i.e., 2Tx mode, in the NR carrier and single-transmission and reception, i.e., 1Tx mode, in the SUL carrier, in order to meet the SAR index, that is, the average maximum transmission power of the terminal in each wireless frame time does not exceed 23dBm. The terminal can determine the uplink time slot proportion of the SUL carrier according to the uplink time slot configuration of the NR carrier.

[0179] For example, taking the NR carrier uplink and downlink time slot ratio DL:S:UL=7:1:2 as an example, the uplink time slot configuration of the NR carrier is 20%, then the uplink time slot of the SUL carrier needs to be reduced by 20%, that is, the uplink time slot of the SUL carrier accounts for 60%.

[0180] In one example, taking a 5G system as an example, Figure 7 As shown, the process of sending carrier scheduling suggestion information from the terminal to the network device is described, including:

[0181] Step 701: The terminal determines whether the current service requires low-latency transmission; when it is determined that the current service does not require low-latency transmission, execute step 702;

[0182] Step 702: The terminal measures the signal quality of the uplink carrier;

[0183] Step 703: determine whether the signal quality of the uplink carrier is greater than the signal quality threshold; when the signal quality of the uplink carrier is greater than the signal quality threshold, execute step 704;

[0184] In the 5G system, the uplink carrier may refer to the NR carrier. The signal quality of the NR carrier may be obtained by measuring the reference signal receiving power (RSRP, Reference Signal Receiving Power) of the NR carrier.

[0185] Step 704: the terminal estimates the uplink transmission power corresponding to the current service; determines whether the uplink transmission power is less than the maximum transmission power; when the uplink transmission power is equal to the maximum transmission power, executes step 705;

[0186] Step 705: Determine whether the uplink transmission data volume corresponding to the currently executed service is greater than or equal to the data volume threshold; if the uplink transmission data volume is greater than or equal to the data volume threshold, execute step 706;

[0187] Step 706: The terminal generates carrier scheduling recommendation information; the carrier scheduling recommendation information includes a recommendation to select the SUL carrier and the uplink carrier to jointly carry the uplink transmission, the uplink time slot ratio corresponding to the SUL carrier, and the reason for the recommendation. The terminal generates the carrier scheduling recommendation information.

[0188] Step 707: The terminal sends the generated carrier scheduling recommendation information to the network device.

[0189] Here, the network device can determine the uplink carrier scheduling method for the terminal based on the carrier scheduling recommendation information sent by the terminal, and combined with the channel quality, signal strength, load conditions, network scheduling complexity and other factors of the uplink carrier, i.e., the NR carrier, and the supplementary uplink carrier, i.e., the SUL carrier of the uplink carrier.

[0190] Here, the terminal generates 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 volume, which has the following advantages:

[0191] When the terminal determines that the uplink transmission power is equal to the maximum transmission power, it can reduce the uplink time slot of the SUL carrier accordingly according to the uplink time slot configuration of the NR carrier based on the uplink transmission demand of the terminal, so that the terminal can meet the SAR indicator requirements.

[0192] In case 4, the terminal generates carrier scheduling recommendation 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 power of the terminal.

[0193] In actual application, if the signal quality of the uplink carrier is high, the terminal can combine the uplink transmission power and the amount of uplink transmission data, and recommend the network side to select the type of carrier that carries the uplink transmission. The terminal can estimate the uplink transmission power corresponding to the current service based on the obtained open-loop control parameters, the current moving speed of the terminal, etc. If the estimated uplink transmission power reaches the maximum transmission power configured on the network side, that is, the radiation generated by the terminal has a greater impact on the user, in this case, in order to meet the SAR index and reduce the impact of the radiation generated by the terminal on the user, if the amount of uplink transmission data corresponding to the current service is small and the current battery power of the terminal is low, it can be recommended that the network side select the supplementary carrier of the uplink carrier, that is, the SUL carrier, to carry the uplink transmission; if the amount of uplink transmission data corresponding to the current service is small and the current battery power of the terminal is high, it can be recommended that the network side select the uplink carrier to carry the uplink transmission.

[0194] The generating carrier scheduling suggestion information based on the uplink transmission power and the uplink transmission data volume corresponding to the current service includes:

[0195] Estimate the uplink transmission power corresponding to the current service;

[0196] Comparing the uplink transmission power with the maximum transmission power configured on the network side to obtain a comparison result;

[0197] When the comparison result indicates that the uplink transmission power is equal to the maximum transmission power, determining whether the amount of uplink transmission data corresponding to the current service is less than a data amount threshold;

[0198] If the uplink transmission data volume is less than the data volume threshold, obtaining the remaining power of the terminal;

[0199] When the remaining power of the terminal is less than the power threshold, carrier scheduling recommendation information is generated; the carrier scheduling recommendation information includes a recommendation to select a SUL carrier to carry uplink transmission and a reason for the recommendation.

[0200] Here, when the remaining power of the terminal is greater than or equal to the power threshold, carrier scheduling recommendation information is generated; the carrier scheduling recommendation information includes a recommendation to select an uplink carrier to bear uplink transmission and a reason for the recommendation.

[0201] It should be noted that, in order to save signaling overhead, the terminal may generate carrier scheduling recommendation information when determining that the SUL carrier needs to be used for uplink transmission, and send the generated carrier scheduling recommendation 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 carrier scheduling recommendation information, and does not send the carrier scheduling recommendation information to the network device, thereby reducing signaling overhead.

[0202] In one example, taking a 5G system as an example, Figure 8As shown, the process of sending carrier scheduling suggestion information from the terminal to the network device is described, including:

[0203] Step 801: The terminal determines whether the current service requires low-latency transmission; when it is determined that the current service does not require low-latency transmission, execute step 802;

[0204] Step 802: The terminal measures the signal quality of the uplink carrier;

[0205] Step 803: Determine whether the signal quality of the uplink carrier is greater than the signal quality threshold; when the signal quality of the uplink carrier is greater than the signal quality threshold, execute step 804;

[0206] In the 5G system, the uplink carrier may refer to the NR carrier. The signal quality of the NR carrier may be obtained by measuring the RSRP of the NR carrier.

[0207] Step 804: the terminal estimates the uplink transmission power corresponding to the current service; determines whether the uplink transmission power is equal to the maximum transmission power; when the uplink transmission power is equal to the maximum transmission power, executes step 805;

[0208] Step 805: determining whether the uplink transmission data volume corresponding to the currently executed service is less than the data volume threshold; if the uplink transmission data volume is less than the data volume threshold, executing step 806;

[0209] Step 806: Obtain the remaining power of the terminal; determine whether the remaining power of the terminal is less than the power advance; when the remaining power of the terminal is less than the power threshold, execute step 807;

[0210] Step 807: The terminal generates carrier scheduling suggestion information;

[0211] The carrier scheduling recommendation information includes a recommendation to select a SUL carrier to carry uplink transmission and a reason for the recommendation.

[0212] Step 808: The terminal sends the generated carrier scheduling recommendation information to the network device.

[0213] Here, the network device can determine the uplink carrier scheduling method for the terminal based on the carrier scheduling recommendation information sent by the terminal, and combined with the channel quality, signal strength, load conditions, network scheduling complexity and other factors of the uplink carrier, i.e., the NR carrier, and the supplementary uplink carrier, i.e., the SUL carrier of the uplink carrier.

[0214] Here, 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 power of the terminal. This has the following advantages:

[0215] The terminal forms a scheduling recommendation plan for the SUL carrier based on the transmission delay requirements of the current service, the signal quality of the uplink carrier, the uplink transmission power, the amount of uplink transmission data, the power status of the terminal and other information. It can provide an uplink enhancement plan for the terminal based on the user's uplink transmission needs and the power status of the terminal, while meeting the requirements of the SAR indicator.

[0216] In one example, taking a 5G system as an example, Fig. 9 As shown, the process of sending carrier scheduling suggestion information from the terminal to the network device is described, including:

[0217] Step 901: The terminal determines whether the current service requires low-latency transmission; when it is determined that the current service does not require low-latency transmission, step 902 is executed;

[0218] Step 902: The terminal measures the signal quality of the uplink carrier;

[0219] Step 903: determine whether the signal quality of the uplink carrier is greater than the signal quality threshold; when the signal quality of the uplink carrier is greater than the signal quality threshold, execute step 904;

[0220] In the 5G system, the uplink carrier may refer to the NR carrier. The signal quality of the NR carrier may be obtained by measuring the RSRP of the NR carrier.

[0221] Step 904: the terminal estimates the uplink transmission power corresponding to the current service; determines whether the uplink transmission power is equal to the maximum transmission power; when the uplink transmission power is equal to the maximum transmission power, executes step 905;

[0222] Step 905: determining whether the uplink transmission data volume corresponding to the currently executed service is less than the data volume threshold; if the uplink transmission data volume is less than the data volume threshold, executing step 906;

[0223] Step 906: obtaining the remaining power of the terminal; determining whether the remaining power of the terminal is greater than or equal to the power advance; when the remaining power of the terminal is greater than or equal to the power threshold, executing step 907;

[0224] Step 907: The terminal does not send carrier scheduling recommendation information to the network device.

[0225] Here, when the amount of uplink transmission data is less than the data amount threshold, the terminal does not send carrier scheduling suggestion information to the network device, which has the following advantages:

[0226] When the terminal determines that it does not need to use the SUL carrier for uplink transmission but needs to use the NR carrier, in order to save signaling overhead, it may not send carrier scheduling recommendation information to the network device.

[0227] It should be noted that in the embodiment of the present invention, taking 5G as an example, the uplink coverage of the NR cell can be enhanced, the uplink data transmission rate can be improved, and the transmission delay can be shortened through the flexible configuration and scheduling of the SUL carrier. At the same time, the SUL carrier is used to provide a targeted uplink enhancement solution in combination with the user's uplink transmission requirements and the power status of the terminal, which can meet the user's transmission requirements without wasting transmission resources.

[0228] By adopting the technical solution of the embodiment of the present invention, the terminal sends the generated carrier scheduling recommendation information to the network device. In this way, the network device can consider the carrier scheduling recommendation information reported by the terminal during the process of scheduling the carrier carrying uplink transmission, thereby meeting the transmission requirements of the terminal and improving the user experience.
