Description

Information receiving and sending method and device

Technical Field

The present application relates to the field of wireless communications technologies, and in particular, to an information receiving and sending method and apparatus.

Background

When performing uplink power control, the terminal device needs to acquire a Path Loss (PL) between the terminal device and the network device. For a scenario in which a low-frequency uplink carrier and a high-frequency uplink carrier are deployed at the same time, taking a 3.5GHz uplink carrier +1.8GHz uplink carrier as an example, the terminal device may measure a path loss corresponding to the 3.5GHz carrier by receiving a downlink synchronization signal or a downlink reference signal on the 3.5GHz downlink carrier, for example, the terminal device may obtain a path loss corresponding to the 3.5GHz carrier according to Reference Signal Received Power (RSRP) measured on the 3.5GHz downlink carrier, and further determine power for sending an uplink signal on the 3.5GHz uplink carrier according to the path loss. However, since the low-frequency downlink carrier is not deployed, the terminal device can only transmit the uplink signal on the 1.8GHz uplink carrier, and cannot receive the downlink signal, so that the terminal device cannot acquire the path loss corresponding to the 1.8GHz carrier by 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 distance of the terminal device on the low-frequency uplink carrier are equal, the path loss can be approximately considered to be related to the carrier frequency only. The path loss can be approximated using equation 1 as follows:

PL ═ X + Y ═ log (d) + Z × (f) formula 1

Where X, Y, Z is a predetermined parameter, 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 equation 1 above. Further, the network device can flexibly adjust P_0LPassing the difference in path loss due to different carrier frequencies through P_0LThe compensation is performed so that the terminal can also employ efficient power control on the low frequency carrier, as shown in the following equations 2(a) and 2 (b). Wherein, P (high frequency) and P (low frequency) are the power of the terminal equipment transmitting the uplink signal on the high frequency uplink carrier and the power of the terminal equipment transmitting the uplink signal on the low frequency uplink carrier respectively, P (high frequency) and P (low frequency)_0HAnd P_0LThe method comprises the steps that high-frequency initial transmission power and low-frequency initial transmission power which are configured for a terminal device by a network device respectively, a is a path loss compensation factor, and b is the sum of a plurality of other parameters irrelevant to path loss.

P (high frequency) ═ P_0H+ a × PL (high frequency) + b equation 2(a)

P (low frequency) ═ P_0L+ a PL (high frequency)) + b formula 2(b)

As can be seen from the above, the above scheme is only applicable to a scenario where the distance between the transmission path of the terminal device on the high-frequency uplink carrier and the transmission path on the low-frequency uplink carrier is equal, and when the distance between the transmission path of the terminal device on the high-frequency uplink carrier and the transmission path on the low-frequency uplink carrier is not equal, the scheme is no longer applicable.

Detailed Description

Embodiments of the present application are described below with reference to the accompanying drawings.

The 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 is smaller than the power of the signal transmitted by the transmitting end. The path loss is related to the distance between the transmitting end and the receiving end, and generally the larger the distance, the larger the path loss. For example, a terminal device closer to the network device transmits an uplink signal to the network device with a smaller path loss, while a terminal device farther from the network device transmits an uplink signal to the network device with a larger path loss. Meanwhile, the path loss is also related to the frequency of the signal, and generally, the higher the frequency of the signal is, the larger the path loss is. In the prior art, the terminal device may determine the uplink signal transmission power P according to the following formula 3, where P₀For the initial transmit power, PL is the path loss, a is the path loss compensation factor, typically a is greater than or equal to 0, and b is the sum of other path loss independent parameters, which are omitted here.

P＝P₀+ a PL + b formula 3

In the development and evolution process of a wireless communication system, a 5G new radio interface (NR) system and a Long Term Evolution (LTE) system may be deployed simultaneously on a frequency band below 6 GHz. At present, NR may be deployed at a frequency of 3.5GHz, but considering that uplink coverage of a system at the frequency cannot match downlink coverage, that is, an uplink communication rate is lower than a downlink communication rate, so that the uplink rate of the system is limited. For this reason, the uplink carrier of the NR system may be deployed on an uplink frequency band of 1.8GHz frequency of the LTE system to enhance uplink coverage of the NR system, or may be deployed on a dedicated uplink frequency band where the LTE system or another system is not deployed, and may be referred to as an added uplink (SUL) carrier.

It should be understood that the solutions provided by the prior art are only applicable to a scenario in which the transmission path of the terminal device on the high-frequency uplink carrier and the transmission path on the low-frequency uplink carrier are equidistant, that is, only applicable to a co-sited SUL scenario. The common-station SUL scenario refers to that the network device for receiving the uplink signal on the high-frequency uplink carrier by the terminal device and the network device for receiving the uplink signal on the low-frequency uplink carrier (i.e., SUL carrier) by the terminal device are the same network device, or the geographical location of the network device for receiving the uplink signal on the high-frequency uplink carrier by the terminal device is the same as the geographical location of the network device for receiving the uplink signal on the low-frequency uplink carrier (i.e., SUL carrier) by the terminal device.

The scheme provided by the embodiment of the application can be applied to the scene of the non co-sited SUL. The non co-sited SUL scenario refers to a situation in which the geographical location of the receiving network device that the terminal device sends the uplink signal on the high-frequency uplink carrier is different from the geographical location of the receiving network device that the terminal device sends the uplink signal on the low-frequency uplink carrier (i.e., the SUL carrier). As shown in fig. 1, the terminal device and the first network device may perform uplink communication and downlink communication, that is, the terminal device transmits an uplink signal to the first network device on a high frequency uplink carrier and receives a downlink signal from the first network device on a high frequency downlink carrier. 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 (i.e., SUL carrier). It should be understood that the first network device and the second network device may be logically one network device, only two portions located at different geographical locations, and the terminal device does not distinguish the first network device from the second network device. Therefore, in the embodiments of the present application, network devices are collectively referred to as a "network device".

The network element related in the embodiment of the application comprises terminal equipment and network equipment. The terminal device can 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 a network device of LTE and/or a network device of NR, and may be a base station (NodeB), an evolved Node B (eNodeB), a base station in a 5G mobile communication system, a next generation mobile communication base station (next generation Node B, gNB), a base station in a future mobile communication system or an access Node in a Wi-Fi system, and the like.

In order to realize that when the distance between a transmission path of the terminal equipment on the high-frequency uplink carrier and the transmission path on the low-frequency uplink carrier is not equal, the power of transmitting the uplink signal on the low-frequency uplink carrier is determined. Referring to fig. 2, an embodiment of the present application provides an information receiving and sending method, where the method includes:

step 200: the network device determines the indication information.

The indication information indicates at least one corresponding relationship between the first power parameter and the second power parameter, where the at least one corresponding relationship includes a corresponding relationship between at least one reference value of the first power parameter and multiple reference values of the second power parameter, the first power parameter is a parameter used for determining power of the terminal device for transmitting an uplink signal to the network device on the first uplink carrier, and the second power parameter is a parameter used for determining power of the terminal device for transmitting an uplink signal to the network device on the second uplink carrier.

In one possible design, the indication information directly includes at least one reference value of the first power parameter and a plurality of 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, the second field includes a plurality of reference values of the second power parameter, and specifically, the first field includes { PLth1, PLth2, …, PLthn }, n values, n is a positive integer, such as 1, 2, 3, 4, 5, 6, etc., and the second field includes { PL1, PL2, …, PLk }, k values, k is a positive integer, such as 2, 3, 4, 5, 6, 7, etc. For another example, the indication information includes a third field, where the third field includes at least one tuple consisting of a reference value of the first power parameter and a reference value of the second power parameter, and specifically, the third field includes n tuples { { PLth1, PL1}, { PLth2, PL2}, …, { PLthn, PLn } }. It should be understood that the indication method of the indication information is only an example, and other indication methods may also be used, which is not limited in the embodiment of the present application.

In one possible design, the first power parameter may be a path loss of the terminal device on a first uplink carrier, and the second power parameter may be a path loss of the terminal device on a second uplink carrier. In another possible design, the first power parameter may be RSRP measured by the terminal device on the first uplink carrier, and the second power parameter may be 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 (i.e., SUL carrier).

Step 210: and the network equipment sends the indication information to the terminal equipment.

Step 220: the terminal equipment receives the indication information from the network equipment, determines the value of the second power parameter according to the value of the first power parameter and one corresponding relation in the at least one corresponding relation, and calculates the power of the uplink signal sent by the terminal equipment to the network equipment on the second uplink carrier according to the value of the second power parameter.

It should be understood that the 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 refer to possible values of the first power parameter. For example, when the first power parameter is the path loss of the terminal device on the high-frequency uplink carrier, the terminal device may obtain the path loss of the high-frequency uplink carrier through RSRP measured on the high-frequency downlink carrier. Similarly, the multiple reference values of the second power parameter mentioned in step 200 refer to predefined possible values of the second power parameter.

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

case 1: the at least one correspondence includes only one correspondence, which is a correspondence of at least one reference value of the first power parameter and a plurality of reference values of the second power parameter.

When the terminal device executes step 220, the terminal device may first measure and obtain a value of the first power parameter, and further, the terminal device generally determines, according to the value of the first power parameter, which two reference values of the at least one reference value of the first power parameter the value of the first power parameter falls within, and then determines a value of the second power parameter corresponding to the range. The terminal device calculates the power of the uplink signal sent by the terminal device 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 power of the uplink signal sent by the terminal device to the network device on the second uplink carrier according to formula 3.

Exemplarily, one corresponding relationship indicated by the indication information is as shown in table 1, the first power parameter is a Path Loss (PLH) of the high frequency uplink carrier, the second power parameter is a path loss (PLL) of the low frequency uplink carrier, wherein the at least one reference value (i.e., a path loss threshold) of the first power parameter includes PLth1, PLth2, …, PLthn, and the plurality of reference values (i.e., path loss values of the low frequency uplink carrier) of the second power parameter includes PL1, PL2, …, PL (n + 1). That is, the correspondence between at least one reference value of the first power parameter and the plurality of reference values of the second power parameter is the correspondence between the plurality of thresholds of the PLH and the plurality of values of the PLL.

TABLE 1

Based on table 1, the terminal device may determine a path loss value PLH0 of the high frequency uplink carrier through RSRP measured at the high frequency downlink carrier, and determine a threshold range in which the PLH0 falls, for example, when PLH0> PLth1, the terminal device determines that the value of the PLL is PL1, when PLth2< PLH0< PLth1, the terminal device determines that the value of the PLL is PL2, … …, and when PLH0< PLthn, the terminal device determines that the value of the PLL is PL (n + 1). After the terminal device determines the value of the PLL, the power of an uplink signal sent by the terminal device to the network device on the low-frequency uplink carrier is calculated according to the value of the PLL.

Exemplarily, one corresponding relationship indicated by the indication information is as shown in table 2, the first power parameter is RSRP measured on the high frequency uplink carrier, the second power parameter is path loss (PLL) of the low frequency uplink carrier, wherein the at least one reference value (i.e., RSRP threshold) of the first power parameter includes RSRPth1, RSRPth2, …, RSRPthn, and the plurality of reference values (i.e., path loss values of the low frequency uplink carrier) of the second power parameter includes PL1, PL2, …, PL (n + 1). That is, the correspondence between at least one reference value of the first power parameter and a plurality of reference values of the second power parameter is the correspondence between a plurality of thresholds of RSRP and a plurality of values of the PLL.

TABLE 2

Based on table 2, the terminal device may directly obtain RSRP0 through measurement on the high-frequency downlink carrier, and determine an RSRP threshold range within which the RSRP0 obtained through measurement falls, thereby determining a value of the PLL.

Therefore, in case 1, the terminal device may 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 further calculate the power of the terminal device for sending the uplink signal to the network device on the second uplink carrier according to the value of the second power parameter, so that the terminal device can perform more accurate uplink power control on the second uplink carrier, and improve the uplink transmission performance.

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

When the terminal device executes step 220, the terminal device determines a target SSB, and determines a corresponding relationship corresponding to the target SSB from the plurality of corresponding relationships. And the terminal equipment determines the value of the second power parameter according to the value of the first power parameter and the corresponding relation corresponding to the target SSB. And the terminal equipment calculates the power of the uplink signal sent by the terminal equipment to the network equipment on the second uplink carrier according to the value of the second power parameter.

Illustratively, the indication information indicates a plurality of correspondence relationships, for example, the indication information may indicate a plurality of tables each similar to that shown in table 1, the plurality of tables being different from each other. The network device sends a plurality of SSBs, different SSBs correspond to different geographical locations, and the terminal device may receive at least one SSB of the plurality of SSBs. The terminal device may determine the received power of each SSB of the received at least one SSB, and set the SSB with the largest received power as the target SSB. Further, the network device may further indicate, to the terminal device, at least one SSB corresponding to each of the multiple correspondence relationships, and the terminal device determines, according to the target SSB and the at least one SSB corresponding to each of the multiple correspondence relationships, a correspondence relationship corresponding to the target SSB in the multiple correspondence relationships, that is, a table corresponding to the target SSB. Then, the terminal device may determine a path loss value of the high-frequency uplink carrier by using RSRP measured on the high-frequency downlink carrier, and determine a threshold range in which the path loss value of the high-frequency uplink carrier falls according to a table corresponding to the target SSB, thereby determining the path loss value of the low-frequency uplink carrier. It should be understood that, here, similar to the path loss value method of the terminal device according to table 1 for the low-frequency uplink carrier, only table 1 is replaced by a table corresponding to the target SSB, and repeated details are omitted. And finally, the terminal equipment calculates the power of the uplink signal sent by the terminal equipment to the network equipment on the low-frequency uplink carrier according to the path loss value of 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 geographic locations, the indication information may indicate a plurality of correspondences, where any one of the plurality of correspondences corresponds to at least one SSB, so that all terminal devices in the cell coverage may select a suitable correspondence according to the geographic location to determine 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, thereby improving the uplink transmission performance.

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

When the terminal device executes step 220, the terminal device determines a target SSB; and the terminal equipment determines the value of the second power parameter according to the value of the first power parameter, the target SSB and the corresponding relation among the first power parameter, the second power parameter and the SSB. And the terminal equipment calculates the power of the uplink signal sent by the terminal equipment to the network equipment on the second uplink carrier according to the value of the second power parameter.

Illustratively, one correspondence relationship indicated by the indication information is shown in table 3, the first power parameter is Path Loss (PLH) of the high frequency uplink carrier, and the second power parameter is path loss (PLL) of the low frequency uplink carrier, wherein the at least one reference value (i.e., path loss threshold) of the first power parameter includes PLth1, PLth2, …, PLthn, and the multiple reference values (i.e., path loss values) of the second power parameter corresponding to SSB1 include PL1-1, PL1-2, …, PL1- (n +1), and the multiple reference values of the second power parameter corresponding to SSB2 include PL2-1, PL2-2, …, PL2- (n +1), … …, and the multiple reference values of the second power parameter corresponding to SSBm include PLm-1, PLm-2, …, PLm- (n + 1). It should be noted that, although the values of the PLLs corresponding to different SSBs are represented by different symbols in table 3, the values of any two PLLs are not limited to be unequal, and actually, the values of the PLLs corresponding to the same SSB but belonging to different PLHs may be equal, and the values of the PLLs 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 PLH0 from RSRP measured on the high-frequency downlink carrier, and determines the threshold range in which PLH0 falls, for example, when PLH0> PLth1 and the target SSB is SSB1, the terminal device determines that the value of PLL is PL 1-1. 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, according to the value of the PLL, the power of the uplink signal sent by the terminal device to the network device on the low-frequency uplink carrier.

Therefore, in case 3, 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 geographic locations, the indication information may indicate the correspondence between the first power parameter, the second power parameter, and the SSB, so that all terminal devices in the cell coverage area may determine the target SSB according to the geographic location where the terminal device is located, and determine the path loss of the second uplink carrier by combining the correspondence between the target SSB and the first power parameter, the second power parameter, and the SSB, so that the terminal device can perform more accurate uplink power control on the second uplink carrier, thereby improving the uplink transmission performance.

In summary, with the method provided in the embodiment shown in fig. 3, the terminal device determines the power of the uplink signal sent to the network device on the second uplink carrier according to at least one corresponding relationship between the first power parameter and the second power parameter indicated by the indication information, and selects one corresponding relationship from the at least one corresponding relationship, so that when the distance between the transmission path of the terminal device on the high-frequency uplink carrier and the transmission path on the low-frequency uplink carrier is not equal, the terminal device can perform more accurate uplink power control on the low-frequency uplink carrier, and improve the uplink transmission performance.

In order to realize that when the distance between a transmission path of the terminal equipment on the high-frequency uplink carrier and the transmission path on the low-frequency uplink carrier is not equal, the power of transmitting the uplink signal on the low-frequency uplink carrier is determined. Referring to fig. 3, an embodiment of the present application provides an information receiving method, including:

step 300: the network device determines the indication information.

The indication information indicates values of the plurality of first power parameters and values of the plurality of second power parameters. The value of any one of the values of the plurality of first power parameters corresponds to the at least one SSB, the value of any one of the values of the plurality of second power parameters corresponds to the at least one SSB, and the first power parameter and the second power parameter are parameters for determining the power at which the terminal device sends the uplink signal to the network device on the second uplink carrier.

In one 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, values of the plurality of second power parameters may include negative values. As shown in fig. 4, the terminal device is located on the connection between the first network device and the second network device, and the farther the distance between the terminal device and the first network device is, the larger the path loss between the terminal device and the first network device is, that is, the larger the path loss on the first uplink carrier corresponding to the first network device is, at this time, the distance between the terminal device and the second network device is correspondingly reduced, so that the smaller the path loss between the terminal device and the second network device is, that is, the smaller the path loss on the second uplink carrier corresponding to the second network device is. Therefore, the path loss compensation factor needs to be a negative value to satisfy the uplink power control requirement.

Step 310: and the network equipment sends the indication information to the terminal equipment.

Step 320: the terminal equipment receives the indication information from the network equipment, and determines the power of sending the uplink signal to the network equipment on the second uplink carrier according to the value of one first power parameter in the values of the first power parameters, the value of one second power parameter in the values of the second power parameters, and the value of the third power parameter.

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 used for determining the path loss of the terminal device on the first uplink carrier, for example, the third power parameter is RSRP measured by the terminal device on the first uplink carrier.

In step 320, in one possible design, the terminal device determines a target SSB, determines a value of a first power parameter corresponding to the target SSB from values of a plurality of first power parameters, and determines a value of a second power parameter corresponding to the target SSB from values of a plurality of second power parameters. And the terminal equipment determines the power of the uplink signal sent to the network equipment 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.

Illustratively, the values of the plurality of first power parameters indicated by the indication information are a plurality of P_0LValue, P_0LThe low-frequency initial transmission power configured for the terminal device for the network device may also be referred to as a nominal power, values of the plurality of second power parameters are a values, and a is a path loss compensation factor. The network device sends a plurality of SSBs, the terminal device may receive at least one SSB of the plurality of SSBs, and the terminal device may determine the received power of each SSB of the received at least one SSB and take the SSB with the largest received power as the target SSB. Further, the network device may also indicate a plurality of P to the terminal device_0LAny one of the values P_0LAt least one SSB corresponding to the value and at least one SSB corresponding to any one a value in the a values, and the terminal equipment is used for processing the data according to the target SSB and the P values_0LAny one of the values P_0LAt least one SSB corresponding to the value and at least one SSB corresponding to any a value in a plurality of a values, and determining a plurality of P_0LP in the value corresponding to the target SSB_0LA value, an a value of the plurality of a values corresponding to the target SSB. Then, the terminal device determines a path loss value PLH0 of the high frequency uplink carrier determined by the RSRP measured at the high frequency downlink carrier, and P corresponding to the target SSB_0LSubstituting the value and the value a corresponding to the target SSB into a formula 3, and further determining that the terminal equipment is in the low-frequency uplinkTransmitting power of uplink signal on carrier to network device, i.e. P (low frequency) ═ P_0L+a*PLH0+b。

Taking a new air interface of a 5G system as an example, referring to the content in section 7.1.1 in the technical specification 38.213v15.2.0 of 3GPP, the power P for sending the physical uplink shared channel determined by the terminal device_PUSCH,b,f,c(i,j,q_dL) can be determined by the following formula

Wherein the interpretation of the individual parameters can be referred to in the specification. The first power parameter may be P herein_{O_PUSCH,b,f,c}(j) The second power parameter may be α herein_b,f,c(j) In that respect Considering P_{O_PUSCH,b,f,c}(j) Is two power parameters P_{O_NOMINAL_PUSCH,f,c}(j) And P_{O_UE_PUSCH,b,f,c}(j) Sum (refer to technical specification 38.213v15.2.0 of 3 GPP), so the above-mentioned first power parameter may also be P here_{O_NOMINAL_PUSCH,f,c}(j) Or P_{O_UE_PUSCH,b,f,c}(j)。

Therefore, with the method provided in the embodiment shown in fig. 3, according to the values of the multiple first power parameters and the multiple second power parameters indicated by the indication information, the terminal device corresponds to at least one SSB, the value of any one of the multiple first power parameters corresponds to at least one SSB, the value of the first power parameter and the value of the second power parameter are selected, and the power for sending the uplink signal to the network device on the second uplink carrier is calculated, so that all terminal devices in the cell coverage area can select the appropriate value of the first power parameter and the appropriate value of the second power parameter according to the geographical location to determine the power for sending the uplink signal to the network device on the second uplink carrier, thereby realizing that when the distance between the transmission path of the terminal device on the high-frequency uplink carrier and the transmission path on the low-frequency uplink carrier is different from each other And when the uplink power is equal to the second uplink power, the terminal equipment can perform more accurate uplink power control on the second uplink carrier, so that the uplink transmission performance is improved.

In order to realize that when the distance between a transmission path of the terminal equipment on the high-frequency uplink carrier and the transmission path on the low-frequency uplink carrier is not equal, the power of transmitting the 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, including:

step 500: the network device determines the indication information.

The indication information indicates values of a plurality of first power parameters and values of a plurality of second power parameters; the value of any one of the multiple values of the first power parameter corresponds to at least one SSB, the first power parameter and the 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 a second uplink carrier.

In one possible design, the first power parameter and the second power parameter are parameters for determining a positional relationship between the terminal device and the network device. For example, the first power parameter is a parameter for determining an included angle between an edge where the network device corresponding to the first uplink carrier and the network device corresponding to the second uplink carrier are located and an edge where the target SSB corresponding to the terminal device is located, or the first power parameter is a parameter for determining an included angle between an edge where the network device corresponding to the first uplink carrier and the network device corresponding to the second uplink carrier are located and an edge where the terminal device and the network device corresponding to the first uplink carrier are located. 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 geographic location of the terminal device is different, the target SSB determined by the terminal device is different, that is, the included angle between the edge where the first network device and the second network device are located and the edge where the terminal device and the first network device are located 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: and the network equipment sends the indication information to the terminal equipment.

Step 520: the terminal equipment receives the indication information from the network equipment, determines a value of a third power parameter according to a value of one first power parameter, a value of a second power parameter and a value of a fourth power parameter in the values of the plurality of first power parameters, and determines the power of sending the uplink signal to the network equipment on a second uplink carrier according to the value of the third power parameter.

The fourth power parameter is a parameter used for determining the power of the terminal device transmitting the uplink signal to the network device on the first uplink carrier. In one possible design, the fourth power parameter is a path loss of the terminal device on the first uplink carrier. Or the fourth power parameter is a parameter used for determining a path loss of the terminal device on the first uplink carrier, for example, the fourth power parameter is RSRP measured by the terminal device on the first uplink carrier.

In a possible design, the terminal device determines the target SSB, and determines a value of the first power parameter corresponding to the target SSB from values of the first power parameters, in step 520. And the terminal equipment 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.

Illustratively, as shown in fig. 6, the values of the plurality of first power parameters are values of a plurality of parameters used for determining the θ value in fig. 6, or are a plurality of θ values. The value of the second power parameter is used to determine the distance d between the first network device and the second network device as shown in fig. 6₀The value of a parameter of value, or d₀The value is obtained. The network device sends a plurality of SSBs, the terminal device may receive at least one SSB of the plurality of SSBs, and the terminal device may determine the received power of each SSB of the received at least one SSB and take the SSB with the largest received power as the target SSB. Further, the network device may also indicate, to the terminal device, at least one SSB corresponding to a value of any one of the plurality of values of the first power parameter,the terminal device determines a value of a first power parameter corresponding to the target SSB in the values of the plurality of first power parameters according to the target SSB and at least one SSB corresponding to any one of the values of the plurality of first power parameters. For example, when the values of the plurality of first power parameters are the values of a plurality of parameters for determining the θ value in fig. 6, the terminal device determines the value of the parameter for determining the θ value in fig. 6 corresponding to the target SSB, and further calculates the θ value according to the value of the parameter for determining the θ value in fig. 6 corresponding to the target SSB. For another example, when the values of the plurality of first power parameters are a plurality of θ values, the terminal device determines the θ value corresponding to the target SSB. When the value of the second power parameter is used to determine the distance d between the first network device and the second network device as shown in fig. 6₀When the value of the parameter of the value is taken, the terminal equipment calculates the value d according to the value of the second power parameter, or when the value of the second power parameter is d₀When the value is obtained, the terminal equipment directly obtains d₀The value is obtained. Further, the terminal device may calculate the distance d between the first network device and the terminal device based on existing methods_RAnd according to the theta value, the d value and d_RValue calculation terminal device and second network device_T. It should be understood that d is calculated at the terminal device_TAfter the value is obtained, the terminal device may also determine the path loss of the low-frequency uplink carrier by using other existing schemes, and further determine the power of the uplink signal sent by the terminal device 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 will d_TSubstituting the value and carrier frequency of the low frequency uplink carrier into equation 1, and d_RThe value and the carrier frequency of the high-frequency uplink carrier are substituted into formula 1, and the difference value between the path loss of the high-frequency uplink carrier and the path loss of the low-frequency uplink carrier can be calculated. Further, the network device can flexibly adjust P_0LPassing the difference of path loss caused by different carrier frequencies and different transmission paths through P_0LCompensating, the terminal device can determine the path loss of the high-frequency uplink carrier through the RSRP measured on the high-frequency downlink carrierAnd (b) calculating the power of the terminal equipment for sending the uplink signal to the network equipment on the low-frequency uplink carrier in combination with the formula 2 (b). The determination of the power of the terminal device for transmitting the uplink signal to the network device on the low-frequency uplink carrier by using the scheme provided by the prior art is only an example and is not limited in this application.

Therefore, with the method provided in the embodiment shown in fig. 5, the terminal device selects the value of the first power parameter according to the values of the plurality of first power parameters and the value of the second power parameter indicated by the indication information, and the value of any one of the plurality of first power parameters corresponds to at least one SSB, so that all terminal devices in the cell coverage area can select a suitable value of the first power parameter according to the geographical location to determine the power of the uplink signal sent to the network device on the second uplink carrier, thereby realizing that when the distance between the transmission path of the terminal device on the high-frequency uplink carrier and the transmission path on the low-frequency uplink carrier is not equal, the terminal device can perform more accurate uplink power control on the second uplink carrier, and improving the uplink transmission performance.
