Detailed Description

Technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived from the embodiments in the present application by a person skilled in the art, are within the scope of protection of the present application.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/", and generally means that the former and latter related objects are in an "or" relationship.

In the related art, the frequency Band of the 5G network is mainly defined in a High frequency Band (UHB), such as n78, whose frequency range is 3300MHz to 3800MHz, and further such as n79, whose frequency range is 4400MHz to 5000MHz, and the millimeter wave frequency reaches more than 24 GHz. Compared with the frequency of the fourth Generation mobile communication technology (4 th-Generation, 4G), which is generally below 3GHz, the high-frequency signal transmission space loss is larger, and the attenuation of 700MHz compared with 3.5GHz in a typical outdoor scene is about 11dB smaller.

In order to cope with the influence of application caused by 5G high-frequency band transmission loss, various technologies are adopted on the network side to enhance the coverage and ensure the user experience, such as a large-scale antenna technology, beam forming, increase of transmitting power and the like. However, on the electronic device side, the volume, structure, battery life, etc. of the electronic device are limited, and the large-scale antenna technology, increasing the transmission power, etc. applicable on the network side cannot be directly applied on the electronic device side. In application requirements, the popularization of short videos, live broadcasts and self media, as well as the requirements of automatic driving, industrial control and the like, put forward new requirements to 5G, the uplink service of the 5G era is predictably and gradually improved, and the development of uplink application is restricted by the development of the uplink performance of the mobile terminal. Therefore, the 5G network introduces a low-frequency secondary frequency band, i.e. a Supplemental Uplink (SUL), for performing Uplink data transmission for the edge users with insufficient Uplink coverage in the high frequency band (e.g. n78, n79, etc.).

In the SUL networking, as shown in fig. 1, when the electronic device is in a coverage area a near the base station, a 5G high frequency band is used for Uplink (UL) and Downlink (DL) data transmission. In an area B far away from the base station, the electronic equipment performs downlink data transmission by adopting a high frequency band and performs uplink data transmission by adopting a low frequency SUL frequency band.

Fig. 2 shows a 3 GPP-defined SUL band and NR/LTE (Long Term Evolution) in the related art. As shown in fig. 2, the SUL is the same as the uplink operating band of NR/LTE, but the SUL band needs to be shared with the band of the existing network (4G or 5G).

The combined frequency bands for NR and SUL are also defined in 3GPP, including the combined definition of n41, n77, n78, n79 frequency bands and SUL frequency bands. For the combined frequency bands of NR and SUL, reference may be made to fig. 3.

However, when the electronic device switches to the SUL frequency band for uplink transmission, there is no scheme for determining the initial transmit power for uplink transmission using the SUL frequency band.

Unlike 4G networks, in 4G networks, the network includes uplink and downlink Frequency bands, which are divided into Frequency Division Duplex (FDD) mode and Time Division Duplex (TDD) mode. The FDD mode is respectively defined with an uplink frequency band and a downlink frequency band, and the TDD mode shares the same frequency band in uplink and downlink time sharing. In the FDD mode, the uplink frequency and the downlink frequency are not greatly different, and the uplink frequency and the downlink frequency of the TDD are the same, so that the coverage of the uplink and the downlink in the 4G network is balanced or approximately balanced. Thus, the electronic device can estimate the amount of power required for uplink transmission based on measurements of the downlink signal.

After the SUL networking is applied, the difference between the NR frequency band and the SUL frequency band is large, and as described above, when the SUL _ n78-n83 networking is applied, the difference between the transmission loss of the wireless signal of 3.5GHz and 700MHz can be as large as 11dB. If the electronic device is switched from the NR frequency band (i.e., the high frequency band) to the SUL frequency band, the initial power is too high, which may cause consumption of useless electric energy, and the reception of the NR downlink signal may be affected by too high harmonic. If the initial power of the electronic device is too low when the electronic device is switched to the SUL band, the success rate of switching to the SUL band may be affected, and even the electronic device may be disconnected.

In order to avoid the problem that the initial transmission power of the electronic device is too large or too small when the electronic device is switched to the SUL frequency band, the application provides an uplink transmission method which can estimate the initial transmission power when the electronic device is switched to the SUL frequency band. The uplink transmission method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Fig. 4 is a timing diagram of an embodiment of an uplink transmission method provided in the present application. As shown in fig. 4, the uplink transmission method 100 includes:

s102, the electronic equipment adopts any first high-frequency band to carry out uplink transmission;

s104, when the electronic device meets the frequency band switching condition, the electronic device obtains frequency band switching information sent by the network device, where the frequency band switching condition is a condition for switching from the high frequency band to the SUL frequency band, and the frequency band switching information includes information for switching from the first high frequency band to the first SUL frequency band, for example, the information for switching from the first high frequency band to the first SUL frequency band is: time frequency resources required by the first SUL frequency band;

s106, the electronic equipment acquires uplink power loss of uplink transmission by adopting a first high-frequency band; and obtaining a target power loss difference between the first SUL frequency band and the first high frequency band;

s108, the electronic equipment determines first initial transmitting power of the electronic equipment for uplink transmission by adopting a first SUL frequency band according to the uplink power loss and the target power loss difference;

and S110, the electronic equipment is switched to a first SUL frequency band to carry out uplink transmission based on the first initial transmitting power.

In the embodiment of the application, before the electronic device is switched from the first high-frequency band to the first SUL frequency band, the uplink power loss of the electronic device for performing uplink transmission by using the first high-frequency band is obtained, and the target power loss difference between the first SUL frequency band and the first high-frequency band is obtained; then, determining first initial transmitting power according to the uplink power loss and the target power loss difference; and switching to the first SUL frequency band for uplink transmission based on the first initial transmitting power. Since the first initial transmission power is not obtained according to the uplink transmission power of the electronic device in the high frequency band, but is obtained according to the uplink power loss of the electronic device in the high frequency band and the target power loss difference, it is possible to avoid that the first initial transmission power is too large or too small, so that the first initial transmission power is a proper value. Therefore, the rationality of power switching to the SUL frequency band is guaranteed, electric energy is saved, and the success rate of switching to the SUL frequency band can be guaranteed.

In one or more embodiments of the present application, S104 may specifically include:

the electronic equipment sends notification information to the network equipment, wherein the notification information is used for notifying the network equipment that the electronic equipment meets the frequency band switching condition;

after receiving the notification information, the network device sends frequency band switching information to the electronic device according to the notification information;

the electronic device receives the frequency band switching information.

In order to obtain an uplink power loss when the electronic device performs uplink transmission by using the first high-frequency band, in one or more embodiments of the present application, the frequency band switching information sent by the network device further includes an actual high-frequency band received power, where the actual high-frequency band received power is an actual received power of the network device when the electronic device performs uplink transmission by using the first high-frequency band.

In this case, the obtaining, in S106, the uplink power loss of the electronic device that performs uplink transmission by using the first high-frequency band may specifically include:

acquiring high-frequency-band transmitting power of the electronic equipment, wherein the high-frequency-band transmitting power is the transmitting power of the electronic equipment when uplink transmission is carried out by adopting a first high-frequency band;

and calculating the difference between the actual receiving power of the high-frequency band and the transmitting power of the high-frequency band to obtain the uplink power loss.

The calculation formula of the uplink power loss is as follows:

loss＝P _launching -P _Receiving (1)

Where loss represents the uplink power loss, P _Launching Indicating high band transmission power, P _Receiving Representing the actual received power in the high frequency band.

In this way, the uplink power loss when the electronic device performs uplink transmission in the first high frequency band is calculated.

In one or more embodiments of the present application, the obtaining of the target power loss difference between the first SUL band and the first high band in S106 may specifically include:

and acquiring target power loss differences corresponding to the first SUL frequency band and the first high frequency band in the corresponding relation between the preset SUL frequency band and the power loss differences between the high frequency band and the power loss differences.

The correspondence between the SUL frequency band and the high frequency band and the power loss difference may be as shown in fig. 5. Assuming that the electronic device needs to switch from the NR frequency band of n78 (i.e., the high frequency band) to the SUL frequency band of n80, the first high frequency band is n78 and the first SUL frequency band is n80. Then, from the column of "Δ loss (maximum) (dB)" in fig. 5, it is found that the corresponding power loss difference is 6.95.

It should be noted that, the correspondence between the SUL frequency band and the difference between the power loss and the high frequency band may be based on a free space loss formula, and the difference data of the wireless spatial path loss of the SUL frequency band to the UHB frequency band under the same position condition is calculated. The free space loss formula is as follows:

loss＝20lg(F)+20lg(D)+32.4 (2)

where F denotes frequency and D denotes distance.

In addition, the correspondence between the SUL band and the power loss difference and the high band may be stored in the electronic device in advance, so that the electronic device may directly query from the correspondence when the target power loss difference needs to be acquired.

In one or more embodiments of the present application, the band switching information may further include a desired received power of the network device. S108 may specifically include:

acquiring a target power correction value of the electronic equipment switched from the high-frequency band to the SUL frequency band;

and calculating the expected received power, the uplink power loss, the target power loss difference and the target power correction value according to a preset initial power calculation function to obtain first initial transmitting power.

The initial power calculation function may be the following formula:

P _ini ＝P _expect +loss+Δloss+θ (3)

wherein, P _ini The initial transmission power (namely the first initial transmission power) of the switching to the SUL frequency band at this time is represented, loss represents the uplink power loss of the electronic device for uplink transmission by adopting the first high-frequency band, Δ loss represents the power loss difference (namely the target power loss difference) between the first SUL frequency band and the first high-frequency band, and θ represents the target power correction value of the switching from the high-frequency band to the SUL frequency band at this time.

How to obtain the target power correction value is exemplified below.

In one or more embodiments of the present application, before S102, the uplink transmission method 100 may further include:

acquiring a preset initial power correction value;

and training power correction values corresponding to N times of frequency band switching of the electronic equipment according to the initial power correction value until the N +1 th time of frequency band switching after the N times of frequency band switching meets the training stopping condition to obtain a plurality of trained power correction values, wherein each time of frequency band switching in the N times of frequency band switching is switched from a high frequency band to an SUL frequency band.

After that, obtaining the target power correction value for the electronic device to switch from the high frequency band to the SUL frequency band at this time may specifically include:

and determining a target power correction value according to the plurality of trained power correction values.

As an example, the plurality of trained power correction values may include a trained power correction value corresponding to each of the N +1 band switches. The target power correction value may be an average of at least some of the plurality of trained power correction values.

Therefore, the power correction values of the N times of frequency band switching of the electronic equipment are trained to obtain a plurality of trained power correction values, and the target power correction value of the current frequency band switching is determined according to the trained power correction values.

The following describes how to train the power correction value for N frequency band switching of the electronic device.

In one or more embodiments of the present application, according to the initial power correction value, training a power correction value corresponding to N-th frequency band switching of the electronic device, until a result of the N +1 th frequency band switching after the N-th frequency band switching satisfies a training stop condition, to obtain a plurality of trained power correction values, which may specifically include:

training power correction values corresponding to N times of frequency band switching of the electronic equipment according to the initial power correction value to obtain N trained power correction values, wherein the N trained power correction values are power correction values corresponding to the 1 st-Nth frequency band switching respectively;

according to the N trained power correction values, switching the (N + 1) th frequency band, and acquiring the actual receiving power of the network side after the (N + 1) th frequency band is switched to the SUL frequency band;

and under the condition that the actual received power is not in the received power fluctuation range, adjusting the initial power correction value, and retraining the power correction value corresponding to the N-time frequency band switching of the electronic equipment until the actual received power of the network side is in the received power fluctuation range under the condition of the N + 1-time frequency band switching after the N-time frequency band switching.

As an example, according to the initial power correction value, training power correction values corresponding to N-times frequency band switching of the electronic device to obtain N trained power correction values may specifically include:

according to the initial power correction value, switching the frequency band for the 1 st time, and acquiring a target parameter for switching the frequency band for the 1 st time;

calculating a power correction value after training corresponding to the 1 st frequency band switching according to the target parameter of the 1 st frequency band switching;

according to the trained power correction value corresponding to the historical frequency band switching, carrying out ith frequency band switching, and obtaining target parameters of the ith frequency band switching, wherein the historical frequency band switching is carried out before the ith frequency band switching, i belongs to [2, N ], and i is an integer;

and calculating a trained power correction value corresponding to the ith frequency band switching according to the target parameter of the ith frequency band switching.

The target parameters for the ith frequency band switching comprise: the first initial transmitting power is switched to the SUL frequency band for uplink transmission at the ith time, the actual receiving power of the network side is switched to the SUL frequency band at the ith time, the uplink power loss of uplink transmission is carried out by adopting the high frequency band before the switching to the SUL frequency band at the ith time, and the power loss difference between the high frequency band and the SUL frequency band is realized under the switching of the ith time;

and the second initial transmitting power is obtained according to the frequency band switching information corresponding to the ith frequency band switching and the trained power correction value corresponding to the historical frequency band switching.

As an example, the received power fluctuation range is based on network equipmentDesired received power P _expect And determining the preset power fluctuation amplitude delta P. For example, the received power fluctuation range may be a range [ P ] as follows _expect -△P，P _expect +△P]。

The following describes an example of training the power correction value for N-time band switching of an electronic device.

Assuming initial power correction value passes through θ ₀ To represent θ ₀ Is 0dB, theta ₀ ′＝θ ₀ ，θ ₀ ' denotes a power correction value after 0 th band switching training.

1. When the electronic device switches from the high frequency band to the SUL band 1 time, theta ₁ ＝θ ₀ '/1, based on this theta ₁ Calculating a second initial transmission power P for switching the electronic device from the high frequency band to the SUL frequency band for the 1 st time _ini 1. The specific formula for calculating the second initial transmission power is as follows:

P

_ini 1＝P _expect 1+loss1+Δloss1+θ ₁ (4)

wherein, P _expect 1 represents the expected receiving power of the electronic equipment on the side of switching to the SUL frequency band network for the 1 st time; loss1 represents the uplink power loss of the high frequency band under the condition that the frequency band of the electronic equipment is switched for the 1 st time; Δ loss1 represents a power loss difference between the SUL band and the high band when the electronic device performs the band switching for the 1 st time, and the power loss difference can also be obtained from a preset correspondence (for example, a correspondence shown in fig. 5) between the SUL band and the power loss difference between the high band.

After calculating the second initial transmission power P _ini 1, calculating a trained power correction value theta corresponding to the switching of the 1 st frequency band ₁ ' the specific calculation formula is as follows:

θ′ ₁ ＝P _ini 1-(loss1+Δloss1)-P _real 1 (5)

wherein, P _real 1 denotes that the electronic device is based on a second initial transmission power P _ini 1 actual reception on the network side during uplink transmissionAnd (4) power.

2. When the electronic device switches from the high frequency band to the SUL frequency band 2 times, similar to the switching of the frequency band 1 time, theta is determined first ₂ ＝(θ ₀ ′+θ ₁ ')/2, then based on θ ₂ Calculating a second initial transmission power P for switching the electronic device from the high frequency band to the SUL frequency band 2 times _ini 2. Then, calculating a trained power correction value theta corresponding to the 2 nd-time frequency band switching ₂ ', the specific calculation formula is as follows:

θ′ ₂ ＝P _ini 2-(loss2+Δloss2)-P _real 2 (6)

loss2 represents the uplink power loss of the high frequency band under the condition that the electronic device switches the frequency band 2 nd time; Δ loss2 represents a power loss difference between the SUL band and the high band when the electronic device switches the band 2 nd time; p is _real 2 denotes that the electronic device is based on the second initial transmission power P _ini 2, actual received power of the network side when performing uplink transmission.

3. Analogous to calculating power correction value theta ₂ In the method of' the present invention, a trained power correction value corresponding to each frequency band switching is calculated.

4. After calculating the trained power correction value corresponding to the N-time frequency band switching, the electronic equipment performs the (N + 1) th frequency band switching and verifies the initial power correction value theta ₀ Whether the value of' is correct or not. The specific implementation process comprises the following steps:

calculating initial transmitting power P for switching the (N + 1) th frequency band _ini (N + 1), wherein the specific calculation formula is as follows:

P _ini (N+1)＝P _expect (N+1)+loss(N+1)+Δloss(N+1)+θ _N+1 (7)

the electronic device then transmits power P based on the initial transmission power _ini And (N + 1), switching to the SUL frequency band for uplink transmission so as to switch the (N + 1) th frequency band.

Then, the electronic device obtains the actual received power P of the network side _real (N + 1), the actual reception power P _real (N + 1) is based on initial emission by the electronic devicePower P _ini (N + 1) actual received power on the network side when switching the band.

When the actual received power P _real (N + 1) in the case where the received power fluctuation range is within, it can be determined that training is completed; when the actual received power P _real (N + 1) adjusting the initial power correction value by the electronic device when the received power is not within the fluctuation range, and retraining the power correction value by switching the frequency band for another N times until the actual received power P _real (N + 1) is within the received power fluctuation range.

After the training is completed, the trained power correction value, namely theta, corresponding to the switching from the 1 st frequency band to the N +1 st frequency band can be obtained ₁ ′、θ ₂ ′……θ _N+1 '. The trained power correction value may be used to determine the power correction value θ for the next frequency band switching, and the specific relationship may be as shown in fig. 6.
