This application claims priority from a Chinese patent application filed with the Chinese Patent Office on August 24, 2018, with application number 201810975018.1, with the application name "A Method and Device for Receiving and Sending Information," the entire contents of which are incorporated herein by reference Applying.

Technical field

The present application relates to the field of wireless communication technologies, and in particular, to a method and device for receiving and transmitting information.

Background technique

When the terminal device performs uplink power control, it is necessary to obtain a path loss (PL) between the terminal device and the network device. For a scenario where both a low-frequency uplink carrier and a high-frequency uplink carrier are deployed, taking a 3.5GHz uplink carrier + a 1.8GHz uplink carrier as an example, a terminal device can measure a 3.5 by receiving a downlink synchronization signal or a downlink reference signal on a 3.5GHz downlink carrier. Path loss corresponding to a GHz carrier. For example, a terminal device can obtain a path loss corresponding to a 3.5 GHz carrier according to a reference signal received power (RSRP) measured on a 3.5 GHz downlink carrier, and then determine the path loss corresponding to the 3.5 GHz carrier. The power of the uplink signal transmitted on the 3.5GHz uplink carrier. However, because no low-frequency downlink carrier is deployed, the terminal device can only send uplink signals on the 1.8 GHz uplink carrier and cannot receive downlink signals. Therefore, the terminal device cannot obtain the path loss corresponding to the 1.8 GHz carrier through the above method.

In the prior art, when the transmission path distance of the terminal device on the high-frequency uplink carrier and the transmission path on the low-frequency uplink carrier are equal, the path loss can be approximately considered to be only related to the carrier frequency. Path loss can be approximated using Equation 1 below:

PL = X + Y * log (d) + Z * log (f) Equation 1

Among them, X, Y, Z are preset parameters, d is the distance of the transmission path, and f is the carrier frequency. Therefore, after determining the path loss corresponding to the high-frequency carrier, the network device may determine the difference between the path loss corresponding to the high-frequency carrier and the path loss corresponding to the low-frequency carrier according to Formula 1 above. Further, the network device can be flexibly adjusted by the value of P _0L, due to different path losses caused by the carrier frequency difference is compensated by P _0L, at low frequencies such that the terminal carrier can be effectively employed power control as follows Equations 2 (a) and 2 (b) are shown. Among them, P (high frequency) and P (low frequency) are the power of the terminal equipment to send uplink signals on the high-frequency uplink carrier and the power of the terminal equipment to send uplink signals on the low-frequency uplink carrier, and P _0H and P _0L are network equipment, respectively. The high-frequency initial transmission power and the low-frequency initial transmission power configured for the terminal device, a is a path loss compensation factor, and b is a sum of other parameters not related to the path loss.

P (high frequency) = P _0H + a * PL (high frequency) + b Formula 2 (a)

P (low frequency) = P _0L + a * PL (high frequency) + b Formula 2 (b)

It can be known from the above that the above solution is only applicable to scenarios where the transmission path of the terminal device on the high-frequency uplink carrier and the transmission path on the low-frequency uplink carrier are equal, and when the transmission path of the terminal device on the high-frequency uplink carrier and When the transmission path distances on the uplink carriers are not equal, this solution will no longer be applicable.

detailed description

The embodiments of the present application will be described below with reference to the drawings.

Path loss refers to the amount of loss introduced by the propagation environment between the transmitting end and the receiving end, that is, the power of the signal received by the receiving end will be less than the power of the signal transmitted by the transmitting end. Path loss is related to the distance between the transmitting end and the receiving end. Generally, the larger the distance, the greater the path loss. For example, a terminal device that is relatively close to a network device sends a small path loss corresponding to the uplink signal sent to the network device, and a terminal device that is relatively far away from the network device sends a path signal corresponding to the network device with a large path loss. At the same time, the path loss is also related to the frequency of the signal. Generally, the higher the frequency of the signal, the larger the path loss. In the prior art, the terminal device can determine the uplink signal transmission power P according to the following formula 3, where P ₀ is the initial transmission power, PL is the path loss, and a is the path loss compensation factor, usually a is greater than or equal to 0, and b is the other and The sum of multiple parameters independent of path loss is omitted here.

P = P ₀ + a * PL + b Equation 3

In the process of the development and evolution of wireless communication systems, a 5G new air interface (NR) system and a long term evolution (LTE) system can be deployed simultaneously on a frequency band below 6 GHz. At present, NR may be deployed on the 3.5GHz frequency first, but considering that the uplink coverage of the system cannot match the downlink coverage on this frequency, that is, the uplink communication rate is lower than the downlink communication rate, making the system's uplink rate limited. For this reason, the uplink carrier of the NR system can be deployed on the 1.8GHz frequency band of the LTE system to enhance the uplink coverage of the NR system, or it can be deployed on a dedicated uplink frequency band, which does not deploy the LTE system or other systems. This uplink carrier may be referred to as an increased uplink (supplementary uplink) (SUL) carrier.

It should be understood that the solutions provided by the prior art are only applicable to scenarios where the transmission path of the terminal device on the high-frequency uplink carrier and the transmission path on the low-frequency uplink carrier are equal in distance, that is, only applicable to the scenario of co-site SUL. The scenario of co-sited SUL means that the receiving network device that sends the uplink signal on the high-frequency uplink carrier and the receiving network device that sends the uplink signal on the low-frequency uplink carrier (that is, the SUL carrier) are the same network device. In other words, the geographic location of the receiving network device where the terminal device sends uplink signals on the high-frequency uplink carrier is the same as the geographic location of the receiving network device where the terminal device sends uplink signals on the low-frequency uplink carrier (that is, the SUL carrier).

The solution provided in the embodiment of the present application can be applied to a non-co-sited SUL scenario. The non-co-sited SUL scenario means that the geographic location of the receiving network device where the terminal device sends uplink signals on the high-frequency uplink carrier is different from the geographic location of the receiving network device where the terminal device sends uplink signals on the low-frequency uplink carrier (that is, the SUL carrier). . As shown in FIG. 1, the terminal device and the first network device can perform uplink communication and downlink communication, that is, the terminal device sends an uplink signal to the first network device on the high-frequency uplink carrier, and sends the uplink signal from the first network device on the high-frequency downlink carrier. Receives downlink signals. The terminal device and the second network device can only perform uplink communication, that is, the terminal device can only send an uplink signal to the second network device on a low-frequency uplink carrier (that is, a SUL carrier). It should be understood that the first network device and the second network device may be logically one network device, only two parts located in different geographical locations, and the terminal device does not distinguish between the first network device and the second network device. Therefore, network devices are collectively referred to in the embodiments of the present application.

The network elements involved in the embodiments of the present application include terminal equipment and network equipment. The terminal device may be a mobile phone, a tablet computer, a virtual reality terminal device, an augmented reality terminal device, a wireless terminal in industrial control, and the like. The network device may be an LTE network device and / or an NR network device, and may be a base station (NodeB), an evolved base station (eNodeB), a base station in a 5G mobile communication system, or a next generation mobile communication base station (nB, gNB). ), Base stations in future mobile communication systems or access nodes in Wi-Fi systems.

In order to realize that when the transmission path of the terminal device on the high-frequency uplink carrier and the transmission path on the low-frequency uplink carrier are not equal in distance, the power for sending an uplink signal on the low-frequency uplink carrier is determined. Referring to FIG. 2, an embodiment of the present application provides a method for receiving and sending information. The method includes:

Step 200: The network device determines the instruction information.

The indication information indicates at least one correspondence between the first power parameter and the second power parameter, and the at least one correspondence includes a correspondence between at least one reference value of the first power parameter and multiple reference values of the second power parameter, where the first The power parameter is a parameter used to determine the power of the terminal device to send the uplink signal to the network device on the first uplink carrier, and the second power parameter is used to determine the power of the terminal device to send the uplink signal to the network device on the second uplink carrier parameter.

In a possible design, the indication information directly includes at least one reference value of the first power parameter and multiple reference values of the second power parameter. For example, the indication information includes a first field and a second field, where the first field includes at least one reference value of the first power parameter, and the second field includes multiple reference values of the second power parameter. Specifically, the first field includes {PLth1, PLth2, ..., PLthn}, a total of n values, n is a certain positive integer, such as 1, 2, 3, 4, 5, 6, etc. The second field includes {PL1, PL2, ..., PLk}, There are a total of k values, k is a certain positive integer, such as 2, 3, 4, 5, 6, 7, and so on. As another example, the indication information includes a third field, where the third field includes a tuple composed of at least one reference value of the first power parameter and a reference value of the second power parameter.

Specifically, the third field includes {{PLth1, PL1}, {PLth2, PL2}, ..., {PLthn, PLn}}, and a total of n tuples. It should be understood that the foregoing indication method of the indication information is merely an example, and of course, there may be other indication methods, which are not limited in the embodiment of the present application.

In a possible design, the first power parameter may be a path loss of the terminal device on the first uplink carrier, and the second power parameter may be a path loss of the terminal device on the second uplink carrier. In another possible design, the first power parameter may be an RSRP measured by the terminal device on the first uplink carrier, and the second power parameter may be a path loss of the terminal device on the second uplink carrier. For example, the first uplink carrier may be a high-frequency uplink carrier, and the second uplink carrier may be a low-frequency uplink carrier (that is, a SUL carrier).

Step 210: The network device sends instruction information to the terminal device.

Step 220: The terminal device receives the instruction information from the network device, determines the value of the second power parameter according to the value of the first power parameter and at least one correspondence relationship, and calculates the terminal according to the value of the second power parameter. The power of the device sending an uplink signal to the network device on the second uplink carrier.

It should be understood that at least one reference value of the first power parameter mentioned in step 200 and the value of the first power parameter mentioned in step 220 both refer to possible values of the first power parameter. Wherein, the at least one reference value of the first power parameter refers to a possible value of the first power parameter defined in advance, and the value of the first power parameter refers to a possible value of the first power parameter obtained through measurement. For example, when When the first power parameter is the path loss of the terminal device on the high-frequency uplink carrier, the terminal device can obtain the path loss on the high-frequency uplink carrier through the RSRP measured on the high-frequency downlink carrier. Similarly, the multiple reference values of the second power parameter mentioned in step 200 refer to possible values of the predefined second power parameter.

Based on the specific content of at least one correspondence relationship indicated by the indication information being different, the step 220 performed by the terminal device may include, but is not limited to, the following situations:

Case 1: The at least one correspondence relationship includes only one correspondence relationship, and the correspondence relationship is a correspondence relationship between at least one reference value of the first power parameter and multiple reference values of the second power parameter.

When the terminal device performs step 220, the terminal device may first measure and obtain the value of the first power parameter. Further, according to the value of the first power parameter, the terminal device generally judges that the value of the first power parameter falls in the first Which two of the at least one reference value of a power parameter is within a range, and then determine the value of the second power parameter corresponding to the range. The terminal device calculates the power of the terminal device to send the uplink signal to the network device on the second uplink carrier according to the value of the second power parameter. For example, the terminal device calculates the terminal device to send the uplink signal to the network device on the second uplink carrier according to Formula 3. Of power.

Exemplarily, a corresponding relationship indicated by the indication information is shown in Table 1. The first power parameter is the path loss (PLH) of the high-frequency uplink carrier, and the second power parameter is the path loss (PLL) of the low-frequency uplink carrier. At least one reference value (ie, path loss threshold) of the first power parameter includes PLth1, PLth2, ..., PLthn, and multiple reference values (ie, path loss value of the low-frequency uplink carrier) of the second power parameter include PL1, PL2, ..., PL (n + 1). That is, the correspondence between at least one reference value of the first power parameter and multiple reference values of the second power parameter is the correspondence between multiple thresholds of the PLH and multiple values of the PLL.

Table 1

Based on Table 1, the terminal device can determine the path loss value PLH0 of the high-frequency uplink carrier through the RSRP measured on the high-frequency downlink carrier and determine the threshold range within which the PLH0 falls. For example, when PLH0> PLth1, the terminal device determines the PLL. The value of is PL1. When PLth2 <PLH0 <PLth1, the terminal device determines that the value of PLL is PL2,... When PLH0 <PLthn, the terminal device determines that the value of PLL is PL (n + 1). After determining the value of the PLL, the terminal device calculates the power of the terminal device to send the uplink signal to the network device on the low-frequency uplink carrier according to the value of the PLL.

Exemplarily, a corresponding relationship indicated by the indication information is shown in Table 2. The first power parameter is the RSRP measured on the high-frequency uplink carrier, and the second power parameter is the path loss (PLL) of the low-frequency uplink carrier. At least one reference value of the first power parameter (ie, the RSRP threshold) includes RSRPth1, RSRPth2, ..., RSRPthn, and multiple reference values of the second power parameter (ie, the path loss value of the low-frequency uplink carrier) include PL1, PL2, ..., PL (n + 1). That is, the correspondence between at least one reference value of the first power parameter and multiple reference values of the second power parameter is the correspondence between multiple thresholds of the RSRP and multiple values of the PLL.

Table 2

Based on Table 2, the terminal device can directly obtain RSRP0 through the measurement of the high-frequency downlink carrier, and determine that the RSRP0 obtained by the measurement falls within the RSRP threshold range, thereby determining the value of the PLL.

Therefore, in case 1, the terminal device can determine the value of the second power parameter according to the corresponding relationship between the measured value of the first power parameter and the indication information, and then calculate the terminal device's value based on the value of the second power parameter. The power of sending an uplink signal to the network device on the second uplink carrier enables the terminal device to perform more accurate uplink power control on the second uplink carrier, and improves uplink transmission performance.

Case 2: At least one correspondence relationship includes a plurality of correspondence relationships, and any correspondence relationship among the plurality of correspondence relationships corresponds to at least one synchronization broadcast signal / physical broadcast channel block (SSB). For example, if a network device sends m SSBs in total, the indication information sent by the network device to the terminal device may indicate m correspondences, where m SSBs correspond to one to one m, and m is a positive integer greater than or equal to 2. . For another example, if the network device sends a total of m SSBs, the indication information sent by the network device to the terminal device may indicate n correspondences, n <m, n and m are positive integers greater than or equal to 2, where each correspondence Corresponds to at least one SSB.

When the terminal device executes step 220, the terminal device determines the target SSB, and determines a corresponding relationship corresponding to the target SSB from a plurality of corresponding relationships. The terminal device determines the value of the second power parameter according to the value of the first power parameter and the corresponding relationship corresponding to the target SSB. The terminal device calculates, according to the value of the second power parameter, the power at which the terminal device sends an uplink signal to the network device on the second uplink carrier.

Exemplarily, the indication information indicates multiple correspondences. For example, the indication information may indicate multiple tables. Each correspondence is similar to that shown in Table 1. The multiple tables are different from each other. The network device sends multiple SSBs, and different SSBs correspond to different geographic locations, and the terminal device can receive at least one SSB of the multiple SSBs. The terminal device may determine the received power of each SSB in the received at least one SSB, and use the SSB with the highest received power as the target SSB. Further, the network device may also indicate to the terminal device at least one SSB corresponding to each of the multiple corresponding relationships, and the terminal device determines the multi-point based on the target SSB and at least one SSB corresponding to each of the multiple corresponding relationships. Among the two corresponding relationships, the corresponding relationship corresponding to the target SSB is to determine the table corresponding to the target SSB. Then, the terminal device can determine the path loss value of the high frequency uplink carrier by using the RSRP measured on the high frequency downlink carrier, and determine the threshold range of the path loss value of the high frequency uplink carrier according to the table corresponding to the target SSB, and then determine Path loss value of the low-frequency uplink carrier. It should be understood that this method is similar to the path loss value method of the low-frequency uplink carrier according to Table 1 by the terminal device, except that Table 1 is replaced with a table corresponding to the target SSB. Finally, the terminal device calculates, according to the path loss value of the low-frequency uplink carrier, the power at which the terminal device sends an uplink signal to the network device on the low-frequency uplink carrier.

Therefore, in case 2, since the correspondence between the path loss of the first uplink carrier and the path loss of the second uplink carrier is different for terminal devices in different geographical locations, the indication information may indicate multiple correspondences, multiple Any correspondence in the correspondence corresponds to at least one SSB, so that all terminal equipment within the cell coverage area can select a suitable correspondence according to the geographical location to determine the path loss of the second uplink carrier, so that the terminal equipment can Perform more accurate uplink power control on the second uplink carrier to improve uplink transmission performance.

Case 3: At least one correspondence relationship includes a correspondence relationship among the first power parameter, the second power parameter, and the SSB.

When the terminal device executes step 220, the terminal device determines the target SSB; the terminal device determines the second power parameter according to the correspondence between the value of the first power parameter, the target SSB, and the first power parameter, the second power parameter, and the SSB. The value of. The terminal device calculates, according to the value of the second power parameter, the power at which the terminal device sends an uplink signal to the network device on the second uplink carrier.

Exemplarily, a corresponding relationship indicated by the indication information is shown in Table 3. The first power parameter is the path loss (PLH) of the high-frequency uplink carrier, and the second power parameter is the path loss (PLL) of the low-frequency uplink carrier. At least one reference value (ie, path loss threshold) of the first power parameter includes PLth1, PLth2, ..., PLthn, SSB1. The multiple reference values of the second power parameter (ie, path loss value of the low-frequency uplink carrier) include PL1-1. , PL1-2, ..., PL1- (n + 1), multiple reference values of the second power parameter corresponding to SSB2 include PL2-1, PL2-2, ..., PL2- (n + 1), ..., SSBm The multiple reference values of the corresponding second power parameter include PLm-1, PLm-2,..., PLm- (n + 1). It should be noted that although the values of the PLLs corresponding to different SSBs in Table 3 are represented by different symbols, it is not limited that the values of any two PLLs are not equal. In fact, those corresponding to the same SSB but belonging to different PLHs The value of the PLL in the value range may be equal, and the value of the PLL corresponding to different SSBs may also be equal, which is not limited in this embodiment of the present application.

table 3

Based on Table 3, the terminal device first determines the target SSB, determines the PLH0 through the RSRP measured on the high-frequency downlink carrier, and determines the threshold range within which the PLH0 falls. For example, when PLH0> PLth1 and the target SSB is SSB1, the terminal device Determine the value of PLL as PL1-1. For another example, when PLth2 <PLH0 <PLth1 and the target SSB is SSBm, the terminal device determines that the value of the PLL is PLm-2. Further, after determining the value of the PLL, the terminal device calculates the power of the terminal device to send the uplink signal to the network device on the low-frequency uplink carrier according to the value of the PLL.

Therefore, in case 3, because the correspondence between the path loss of the first uplink carrier and the path loss of the second uplink carrier is different for terminal devices in different geographical locations, the indication information may indicate the first power parameter, the second Correspondence between the three power parameters and the SSB, so that all terminal equipment within the cell coverage area can determine the target SSB according to the geographical location, and combine the target SSB with the first power parameter, the second power parameter, and the SSB. The correspondence relationship determines the path loss of the second uplink carrier, so that the terminal device can perform more accurate uplink power control on the second uplink carrier, and improve uplink transmission performance.

In summary, using the method provided in the embodiment shown in FIG. 3, the terminal device selects one of the at least one correspondence relationship to determine the relationship between the first power parameter and the second power parameter indicated by the indication information. The power of the uplink signal sent to the network device on the second uplink carrier, so that when the transmission path of the terminal device on the high-frequency uplink carrier and the transmission path on the low-frequency uplink carrier are not equal, the terminal device can perform the low-frequency uplink carrier. More accurate uplink power control improves uplink transmission performance.

In order to realize that when the transmission path of the terminal device on the high-frequency uplink carrier and the transmission path on the low-frequency uplink carrier are not equal in distance, the power for sending an uplink signal on the low-frequency uplink carrier is determined. Referring to FIG. 3, an embodiment of the present application provides a method for receiving information. The method includes:

Step 300: The network device determines the instruction information.

The indication information indicates values of multiple first power parameters and values of multiple second power parameters. Any one of the values of the plurality of first power parameters corresponds to at least one SSB, and any one of the values of the plurality of second power parameters corresponds to at least one SSB. Correspondingly, the first power parameter and the second power parameter are parameters for determining a power of the terminal device to send an uplink signal to the network device on the second uplink carrier.

In a possible design, the first power parameter may be a nominal power, and / or the second power parameter may be a path loss compensation factor. When the second power parameter is a path loss compensation factor, the values of the plurality of second power parameters may include a negative value. As shown in FIG. 4, the terminal device is located on the connection between the first network device and the second network device. The further the distance between the terminal device and the first network device, the greater the path loss between the terminal device and the first network device. That is, the path loss on the first uplink carrier corresponding to the first network device is larger, and the distance between the terminal device and the second network device is reduced accordingly, so the path loss between the terminal device and the second network device is smaller. That is, the smaller the path loss on the second uplink carrier corresponding to the second network device. Therefore, the path loss compensation factor needs to be negative to meet the requirements of uplink power control.

Step 310: The network device sends instruction information to the terminal device.

Step 320: The terminal device receives the instruction information from the network device, and according to the value of the first power parameter among the values of the plurality of first power parameters and the value of the second power parameter among the values of the plurality of second power parameters. The value and the value of the third power parameter determine the power of sending an uplink signal to the network device on the second uplink carrier.

The third power parameter is a path loss of the terminal device on the first uplink carrier, or the third power parameter is a parameter for determining the path loss of the terminal device on the first uplink carrier, for example, the third power parameter is the terminal The device measures the obtained RSRP on the first uplink carrier.

For step 320, in a possible design, the terminal device determines the target SSB, and determines the value of the first power parameter corresponding to the target SSB from the values of the plurality of first power parameters, and from the plurality of second power parameters. The value of the power parameter determines the value of the second power parameter corresponding to the target SSB. The terminal device determines to send an uplink signal to the network device on the second uplink carrier according to the value of the first power parameter corresponding to the target SSB, the value of the second power parameter corresponding to the target SSB, and the value of the third power parameter. Of power.

Exemplarily, the values of the plurality of first power parameters indicated by the indication information are multiple P _0L values, where P _0L is the initial low-frequency transmit power configured by the network device for the terminal device, which may also be referred to as the nominal power. The value of the two power parameters is a, and a is a path loss compensation factor. The network device sends multiple SSBs, the terminal device can receive at least one SSB of the multiple SSBs, and the terminal device can determine the received power of each SSB in the received at least one SSB, and use the SSB with the highest received power as the target SSB . Further, the network device may indicate to the terminal device of any of the plurality of P _0L a value corresponding to the value P _0L least one SSB, and any one of a plurality of values of at least one of a value corresponding to a SSB, the target terminal device SSB, any one of a plurality of P values _0L _0L a P value corresponding to at least one SSB, and any one of a plurality of values of at least one of a value corresponding to a SSB, determining a plurality of values of P and P _0L target corresponding to SSB _0L value, a value corresponding to the target SSB among multiple a values. Then, the terminal device brings the path loss value PLH0 of the high-frequency uplink carrier determined by the RSRP measured on the high-frequency downlink carrier, the P _0L value corresponding to the target SSB, and the a value corresponding to the target SSB into Equation 3, Furthermore, the power of the terminal device to send the uplink signal to the network device on the low-frequency uplink carrier is determined, that is, P (low frequency) = P _0L + a * PLH0 + b.

Taking the new air interface of the 5G system as an example, referring to section 7.1.1 of the 3GPP technical specification 38.213v15.2.0, the power determined by the terminal device to send the physical uplink shared channel P _{PUSCH, b, f, c} (i, j , q _d , l) can be determined by the following formula:

The explanation of each parameter can refer to the explanation in this technical specification. The first power parameter may be _{PO_PUSCH, b, f, c} (j) here, and the second power parameter may be α _{b, f, c} (j) here. Considering that _{PO_PUSCH, b, f, c} (j) is the _sum of two power parameters _{PO_NOMINAL_PUSCH, f, c} (j) and _{PO_UE_PUSCH, b, f, c} (j) (refer to 3GPP technical specification 38.213v15. 2.0), so the aforementioned first power parameter may also be _{PO_NOMINAL_PUSCH, f, c} (j) or _{PO_UE_PUSCH, b, f, c} (j) here.

Therefore, by adopting the method provided in the embodiment shown in FIG. 3, the terminal device according to the values of the plurality of first power parameters and the values of the plurality of second power parameters indicated by the instruction information, and the selection of the plurality of first power parameters The value of any first power parameter among the values corresponds to at least one SSB, and the value of any second power parameter among the values of multiple second power parameters is at least one SSB, and the value of the first power parameter is selected. Value and the value of the second power parameter to calculate the power for sending uplink signals to the network equipment on the second uplink carrier, so that all terminal equipment within the cell coverage area can select the appropriate first power according to the geographical location The value of the parameter and the value of the second power parameter determine the power of the uplink signal sent to the network device on the second uplink carrier, thereby realizing the transmission path of the terminal device on the high-frequency uplink carrier and the low-frequency uplink carrier. When the transmission path distances are not equal, the terminal device can perform more accurate uplink power control on the second uplink carrier to improve uplink transmission performance.

In order to realize that when the transmission path of the terminal device on the high-frequency uplink carrier and the transmission path on the low-frequency uplink carrier are not equal in distance, the power for sending an uplink signal on the low-frequency uplink carrier is determined. Referring to FIG. 5, an embodiment of the present application provides an information receiving method. The method includes:

Step 500: The network device determines the instruction information.

Wherein, the indication information indicates a value of a plurality of first power parameters and a value of a second power parameter; any one of the values of the plurality of first power parameters corresponds to at least one SSB. A power parameter and a second power parameter are parameters for determining a third power parameter, and the third power parameter is a path loss of the terminal device on the second uplink carrier.

In a possible design, the first power parameter and the second power parameter are parameters for determining a position relationship between the terminal device and the network device. For example, the first power parameter is a parameter used to determine an included angle between the edge of the network device corresponding to the first uplink carrier and the network device corresponding to the second uplink carrier and the edge of the target SSB corresponding to the terminal device, or the first The power parameter is a parameter for determining an included angle between the edge of the network device corresponding to the first uplink carrier and the network device corresponding to the second uplink carrier and the edge of the terminal device corresponding to the network device corresponding to the first uplink carrier. The second power parameter is a parameter for determining a distance between the network device corresponding to the first uplink carrier and the network device corresponding to the second uplink carrier. It should be understood that, as shown in FIG. 6, when the geographical locations of the terminal devices are different, the target SSBs determined by the terminal devices are different, that is, the side where the first network device and the second network device are located, and the terminal device and the first network. The included angle of the edge of the device changes with the change of the target SSB, and the distance between the first network device and the second network device generally remains unchanged after the deployment is completed.

Step 510: The network device sends instruction information to the terminal device.

Step 520: The terminal device receives the instruction information from the network device, and determines the first power parameter according to the value of the first power parameter, the value of the second power parameter, and the value of the fourth power parameter. The value of the three power parameters, and the power of sending an uplink signal to the network device on the second uplink carrier according to the value of the third power parameter.

The fourth power parameter is a parameter for determining a power of the terminal device to send an uplink signal to the network device on the first uplink carrier. In a possible design, the fourth power parameter is a path loss of the terminal device on the first uplink carrier. Alternatively, the fourth power parameter is a parameter for determining a path loss of the terminal device on the first uplink carrier, for example, the fourth power parameter is an RSRP measured and obtained by the terminal device on the first uplink carrier.

For step 520, in a possible design, the terminal device determines the target SSB, and determines the value of the first power parameter corresponding to the target SSB from the values of multiple first power parameters. The terminal device determines the value of the third power parameter according to the value of the first power parameter, the value of the second power parameter, and the value of the fourth power parameter corresponding to the target SSB.

Exemplarily, as shown in FIG. 6, the values of the plurality of first power parameters are values of multiple parameters used to determine the value of θ in FIG. 6, or are values of multiple θ. The value of the second power parameter is a value used to determine a value d _{0 of the} distance between the first network device and the second network device in FIG. 6, or a value of d ₀ . The network device sends multiple SSBs, the terminal device can receive at least one SSB of the multiple SSBs, and the terminal device can determine the received power of each SSB in the received at least one SSB, and use the SSB with the highest received power as the target SSB . Further, the network device may also indicate to the terminal device at least one SSB corresponding to any one of the values of the plurality of first power parameters, and the terminal device may determine the target SSB and the plurality of first power parameters. At least one SSB corresponding to the value of any one of the first power parameters is determined, and the value of the first power parameter corresponding to the target SSB among the values of the plurality of first power parameters is determined. For example, when the values of the plurality of first power parameters are multiple values used to determine the value of θ in FIG. 6, the terminal device determines a parameter corresponding to the target SSB and used to determine the value of θ in FIG. 6. And further calculate the value of θ according to the value of the parameter corresponding to the target SSB for determining the value of θ in FIG. 6. For another example, when the values of the plurality of first power parameters are multiple θ values, the terminal device determines the θ value corresponding to the target SSB. When the value of the second power parameter is a parameter used to determine the value of the distance d ₀ between the first network device and the second network device in FIG. 6, the terminal device calculates d according to the value of the second power parameter. When the value of the second power parameter is d ₀ , the terminal device directly obtains the value of d ₀ . Further, the terminal device may calculate the distance d _R between the first network device and the terminal device based on the existing method, and calculate the distance d _T between the terminal device and the second network device according to the value of θ, d, and d _R. . It should be understood that after the terminal device calculates the d _T value, the terminal device may also use other existing solutions to determine the path loss of the low frequency uplink carrier, and further determine the power of the terminal device to send the uplink signal to the network device on the low frequency uplink carrier .

For example, in combination with the solutions provided by the prior art, the terminal device substitutes the d _T value and the carrier frequency of the low-frequency uplink carrier into Formula 1, and the d _R value and the carrier frequency of the high-frequency uplink carrier into Formula 1, and the high-frequency uplink can be calculated. The difference between the path loss of the carrier and the path loss of the low-frequency uplink carrier. Further, the network device can be flexibly adjusted by the value of P _0L, since the path different carrier frequencies and different transmission path loss caused by a difference compensating P _0L, the terminal device can be obtained by measuring the downlink carrier frequency The path loss value of the high-frequency uplink carrier determined by RSRP is combined with formula 2 (b) to calculate the power of the terminal device to send the uplink signal to the network equipment on the low-frequency uplink carrier. In combination with the solutions provided in the prior art, determining the power of the terminal device to send the uplink signal to the network device on the low-frequency uplink carrier is merely an example, and is not intended to limit the present application.

Therefore, by using the method provided in the embodiment shown in FIG. 5, the terminal device uses the values of multiple first power parameters and values of the second power parameter indicated by the indication information, and among multiple values of the first power parameter. The value of any of the first power parameters corresponds to at least one SSB, and the terminal device selects the value of the first power parameter, so that all terminal devices within the coverage area of the cell can select a suitable first power according to the geographical location. The value of the parameter determines the power of the uplink signal sent to the network device on the second uplink carrier, thereby realizing that when the transmission path of the terminal device on the high-frequency uplink carrier and the transmission path on the low-frequency uplink carrier are not equal, the terminal The device can perform more accurate uplink power control on the second uplink carrier to improve uplink transmission performance.
