However, in a sensing scenario, the path loss information of the uplink communication signal and the uplink sensing signal are different, so the reported transmit power headroom is inaccurate.

[0023] The following will be combined with the drawings in the present disclosure to clearly and completely describe the technical solutions in the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0024] It should be noted that, in the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present disclosure should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0025] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0026] In the description of the present disclosure, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "a plurality" means two or more.

[0027] In a wireless communication system, a user equipment (UE) can report the transmit power margin of an uplink communication signal to a base station. The transmit power margin of an uplink communication signal is equal to the difference between the maximum transmit power of the uplink communication signal of the terminal (which can also be called the nominal maximum transmit power of the terminal) and the actual transmit power based on the path loss estimation. However, in a perception scenario, the actual transmit power of the perception signal based on the path estimation of the terminal and the actual transmit power of the communication signal are no longer suitable for the perception signal, and the maximum transmit power of the uplink communication signal is no longer suitable for the uplink perception signal. In this way, the transmit power margin reported by the terminal will no longer be accurate, and it is necessary to redefine the maximum transmit power suitable for the uplink perception signal, and report the transmit power margin of the uplink perception signal to the base station to better assist the base station in scheduling the uplink perception signal resources. However, in the traditional method, there is no definition of the maximum transmit power of the uplink perception signal, nor is there a configuration of the transmit power margin of the uplink perception signal.

[0028] In a communication system, the transmission power of the uplink signal is less than or equal to the maximum transmission power P of the uplink signal.CMAX,f,c (i.e., the nominal maximum transmission power of the uplink signal). CMAX,f,c Greater than or equal to a lower power limit value P CMAX_L,f,c , and is less than or equal to a power upper limit value, as shown in the following formula:

[0029] P CMAX_L,f,c ≤P CMAX,f,c ≤P CMAX_H,f,c with

[0030] P CMAX_L,f,c =MIN{P EMAX,c –ΔT C,c ,(P PowerClass –ΔP PowerClass )–

[0031] MAX(MAX(MPR c +ΔMPR c ,A_MPR c )+ΔT IB,c +ΔT C,c +ΔT RxSRS ,P_MPR c )}

[0032] P CMAX_H,f,c =MIN{P EMAX,c ,P PowerClass –ΔP PowerClass}

[0033] Among them, the maximum transmission power of the uplink communication signal is related to the terminal capability, the frequency band, frequency band, bandwidth and modulation method of the uplink signal. The meaning of each parameter in the above power can be referred to the relevant technology, and the embodiments of the present disclosure will not be repeated here.

[0034] The transmit power margin PH of the uplink signal is equal to the maximum transmit power P CMAX,f,cSubtract the actual transmit power based on the path loss estimate. The traditional method includes three types of transmit power headroom reports (PHR), namely Type 1PHR, Type 2PHR and Type 3PHR. Type 1PHR is for the transmit power headroom report of the uplink data signal / channel (physical uplink shared channel (PUSCH)); Type 2PHR is for the transmit power headroom report of the uplink control signal / channel (physical uplink control channel (PUCCH)) and the uplink data signal / channel in the EN-DC system; Type 3PHR is for the transmit power headroom report of the sounding reference signal (SRS).

[0035] However, in the interawareness integrated system, the maximum transmit power of the uplink perception signal may be affected by the specific perception target. The formula for the uplink communication signal (i.e., the formula for the maximum transmit power of the uplink signal mentioned above) is no longer applicable to the uplink perception signal. Furthermore, the three transmit power margin reporting PHRs cannot accurately reflect the transmit power margin of the uplink perception signal.

[0036] In this regard, an embodiment of the present disclosure provides an information transmission method, where a terminal can send first indication information, and the first indication information is used for the transmit power margin of an uplink perception signal. The terminal can determine the transmit power margin of the uplink perception signal, because the transmit power margin determined by the terminal is the transmit power margin of the uplink perception signal. In this way, the transmit power margin of the uplink perception signal reported by the first indication information can be adapted to the uplink perception signal, which is more accurate, thereby better helping the base station to perform scheduling.

[0037] The information transmission method provided by the embodiments of the present disclosure can be applied to systems of various communication formats. For example, the information transmission provided by the embodiments of the present disclosure can be applied to systems including, but not limited to, long term evolution (LTE) systems, various versions based on LTE evolution, fifth generation mobile communication technology (5G) systems, future mobile communication networks (such as 6G mobile communication networks), or multiple communication convergence systems.

[0039] The terminal 101 may be an IoT device, a mobile phone, a vehicle-mounted device, etc. The base station 102 may be a communication base station, a sensing base station, etc.

[0040] In some embodiments, the terminal 101 may determine the transmit power headroom of the uplink sensing signal, and send first indication information to indicate the transmit power headroom to the base station 102. The base station 102 may receive the first indication information, and perform scheduling based on the transmit power headroom indicated by the first indication information.

A terminal may sometimes also be referred to as a user, user equipment (UE), access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication equipment, UE agent or UE device, etc., but the embodiments of the present application are not limited to this.

[0042] In some embodiments, the base station can be a base station or an evolved base station (eNB or eNodeB) in long term evolution (LTE), long term evolution advanced (LTEA), a base station device in a 5G network, or a base station in a future communication system, etc. The base station may include various macro base stations, micro base stations, home base stations, wireless remote stations, reconfigurable intelligent surfaces (RISs), routers, wireless fidelity (WIFI) devices, or various network side devices such as primary cells and collaborative cells (secondary cells).

[0043] It should be noted that Figure 1 This is just an exemplary framework diagram. Figure 1 The number of devices included in the Figure 1 In addition to the devices shown, the communication system may also include other devices, such as relay nodes, etc.

[0044] The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0045] The information transmission method provided by the embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0046] The information transmission method provided by the embodiment of the present disclosure can be applied to Figure 1 In the communication system shown is a first node 101 . Figure 2 A schematic diagram of a flow chart of an information transmission method is shown, such as Figure 2 As shown, the information transmission method includes the following S201.

[0047] S201. The terminal sends first indication information.

[0048] The first indication information is used to indicate the transmit power margin of the uplink perception signal.

[0049] Since the uplink sensing signal is sent by the terminal and then received by the base station after being reflected by the sensing target, the loss of the uplink sensing signal is relatively large. Therefore, the transmit power margin of the uplink communication signal determined based on the path loss of the uplink communication signal is no longer suitable for the uplink sensing signal. When reporting the transmit power margin, it is necessary to determine the transmit power margin suitable for the uplink sensing signal. To this end, the terminal can determine the maximum transmit power and actual transmit power of the uplink sensing signal, thereby determining the transmit power margin of the uplink sensing signal, so that the transmit power margin reported by the terminal is more accurate, and further improves the accuracy of base station scheduling.

[0050] In some embodiments, the transmit power margin is determined based on the maximum transmit power and the actual transmit power of the uplink perception signal; the actual transmit power is determined according to the reference path loss of the uplink perception signal.

[0051] Since the path loss information of the uplink communication signal and the maximum transmit power of the uplink communication signal are no longer applicable to the uplink perception signal, the transmit power margin determined based on the two is no longer applicable to the uplink perception signal. In this case, the terminal can re-determine the maximum transmit power of the uplink perception signal, and determine the transmit power margin of the uplink perception signal based on the maximum transmit power of the uplink perception signal, so that the determined transmit power margin of the uplink perception signal is more accurate.

[0052] The following is a description of the maximum transmit power of the uplink sensing signal.

[0053] Since the maximum transmit power of the uplink signal is determined based on the upper limit and lower limit of the uplink signal, the terminal may determine the upper limit and lower limit of the maximum transmit power of the uplink perception signal before determining the maximum transmit power of the uplink perception signal.

[0054] The lower limit value and the upper limit value of the maximum transmit power of the uplink perception signal are determined based on multiple perception signal transmit power parameters, and the perception signal transmit power parameters include at least one of the following: a first maximum transmit power, a second maximum transmit power, a relaxation amount, a reduction amount of the second maximum transmit power, an additional reduction amount of the second maximum transmit power, a power control maximum reduction amount of the second maximum transmit power, and a perception offset;

[0055] The first maximum transmit power is a configured maximum transmit power, and the second maximum transmit power is a maximum transmit power that depends on the terminal capability.

[0056] In some embodiments, the upper limit value of the maximum transmit power of the uplink perception signal is determined based on the first maximum transmit power, the second maximum transmit power, and the relaxation amount of the second maximum transmit power;

[0057] The lower limit value of the uplink perception signal is determined based on the first maximum transmit power, the second maximum transmit power, the relaxation amount of the second maximum transmit power, the reduction amount of the second maximum transmit power, the additional reduction amount of the second maximum transmit power, and the power control maximum reduction amount of the second maximum transmit power.

[0058] The maximum transmit power of the uplink sensing signal is recorded as It satisfies the following formula:

[0059]

[0060] For parameters parameter is the first maximum transmit power and can be configured by the base station.

[0061] Among them, the parameters It can be obtained through high-level configuration of the base station, such as by radio resource control (RRC) or medium access control element (MAC CE). It is the calculation of the maximum transmit power dedicated to the uplink sensing signal.

[0062] Or, if the terminal is not configured with parameters Then the parameter Equal to the configured maximum transmit power P of the uplink communication signal EMAX (ie the first maximum transmission power of the uplink communication signal).

[0063] Alternatively, the parameter The maximum transmit power P that can be configured for the uplink communication signal EMAX and the first offset (Δ), for example,

[0064] The first offset is configured by a base station, for example, by RRC or MAC or a physical downlink control channel (PDCCH) or a physical downlink shared channel (PDSCH); and / or the first offset is related to a parameter (or characteristic) of a perception target or a perception area, for example, the first offset is related to a type of perception target, a radar cross section (RCS), and a location area.

[0065] For parameters parameter is the second maximum transmission power, and the parameter is the relaxation amount, i.e., the relaxation amount of the maximum transmit power depending on the terminal capability. In the traditional method, four groups of maximum transmit powers based on the terminal capability and their corresponding relaxation amounts are defined. As shown in Table 1:

[0066] Table 1

[0067]

[0068]

[0069]

[0070] The second maximum transmission power includes powers corresponding to multiple power classes, and different power classes correspond to different frequency bands and tolerances.

[0071] Since the uplink sensing signal needs to be reflected by the sensing target, its energy loss is greater than that of the uplink communication signal. Therefore, the maximum transmission power required for the uplink sensing signal is greater. In this case, the second maximum transmission power and the relaxation amount need to be adjusted.

[0072] In some embodiments, the second maximum transmit power and the relaxation amount of the second maximum transmit power belong to at least one newly added set of sensing configurations.

[0073] For example, one or more groups of perception configurations are added based on Table 1, and one group of perception configurations includes a second maximum transmit power and at least one relaxation amount of the second maximum transmit power. For example, a group of power class 4 and a corresponding relaxation amount tolerance are defined. The newly added power class 4 and the corresponding relaxation amount are dedicated to the transmission of uplink perception signals.

[0074] For another example, multiple groups of perception configurations are added, and one group of perception configurations includes a second maximum transmit power and at least one relaxation amount of the second maximum transmit power. That is, multiple groups of power classes and corresponding relaxation amounts of tolerance are added. The newly added multiple groups of power classes and corresponding relaxation amounts are dedicated to the transmission of uplink perception signals.

[0075] In one possible implementation, the second maximum transmit power included in the target sensing configuration in at least one newly added set of sensing configurations is the second maximum transmit power supported by all frequency bands, and the target sensing configuration is a predefined set of sensing configurations in at least one newly added set of sensing configurations.

[0076] For example, one power class (i.e., target perception configuration) is defined in the newly added multiple power classes as the second maximum transmit power supported by all frequency bands by default. That is, the UE can send uplink perception signals at the maximum output power of the default power class on all frequency bands. The remaining power classes only support the maximum output power of uplink perception signals on some frequency bands, that is, the UE sends uplink perception signals at the maximum output power of non-default power classes on some frequency bands.

[0077] It is understandable that the newly added UE maximum output power for uplink perception signals is greater than power class 1, power class 1.5, power class 2 and / or power class 3.

[0078] In some other embodiments, the relaxation amount belongs to multiple groups of perception configurations, and one group of perception configurations includes a maximum transmission power of an uplink communication signal depending on the terminal capability and a newly added relaxation amount of at least one uplink perception signal. A relaxation amount is added for power class 1, power class 1.5, power class 2, and power class 3, respectively, and the newly added relaxation amount is used for sending uplink perception signals. That is, one group of perception configurations includes a maximum transmission power of an uplink communication signal based on the terminal capability, a relaxation amount of the maximum transmission power of the uplink communication signal based on the terminal capability, and a newly added relaxation amount.

[0079] The perception configuration also includes a relaxation amount of at least one uplink communication signal. In a group of perception configurations, the relaxation amount of at least one uplink communication signal is greater than the relaxation amount of at least one uplink communication signal. For the same group of power classes, the newly added relaxation amount for sending uplink perception signals is greater than the relaxation amount for sending uplink communication signals. This means that for perception services, the maximum output power of the uplink perception signal can have greater adjustability and flexibility based on the maximum output power corresponding to the power class.

[0080] For parameter MPR S , parameter MPR S It is the reduction amount (or the reducible amount or the maximum reduction amount) of the second maximum transmit power, which is related to the waveform and modulation mode of the uplink perception signal and is determined based on the waveform and adjustment mode of the uplink perception signal.

[0081] For parameter A_MPR S , parameter A_MPR Sis an additional reduction amount of the second maximum output power (also referred to as an additional reducible amount, an additional maximum reducible amount). The additional reduction amount of the second maximum transmit power is determined based on a network signaling value corresponding to the additional reduction amount.

[0082] The network signaling value is related to the parameters of the sensing target or sensing area. For example, it is related to the frequency band of the uplink sensing signal, the additional spectrum emission value, the type of the sensing target, the RCS of the sensing target, and / or the regional location of the sensing target. That is, the network signaling value can be uniquely determined by the frequency band of the uplink sensing signal, the additional spectrum emission value, and the characteristics of the sensing target / area.

[0083] The remaining parameters in the formula of the maximum transmit power of the uplink sensing signal are the same as the parameters of the maximum transmit power of the uplink communication signal in the traditional method. For example, the parameter P_MPR is the maximum power control reduction of the maximum transmit power of the uplink communication signal based on the terminal capability, that is, the maximum output power reduction to meet the electromagnetic energy radiation absorption requirement. Among them, the parameter P_MPR can be the maximum power control reduction of the uplink communication signal based on the terminal capability, or it can be the maximum power control reduction of the second maximum transmit power.

[0084] The perception signal transmit power parameter may further include a perception offset. Two methods of maximum transmit power of uplink perception signals will be described below based on the perception offset.

[0085] Mode 1: The upper limit value of the maximum transmit power of the uplink perception signal is determined based on at least one of the following: a perception offset, a first maximum transmit power, a third maximum transmit power, and a relaxation amount of the third maximum transmit power;

[0086] The lower limit of the maximum transmit power of the uplink perception signal is determined based on at least one of the following: a perception offset, a first maximum transmit power, a third maximum transmit power, a relaxation of the third maximum transmit power, a reduction of the third maximum transmit power, and an additional reduction of the third maximum transmit power; the third maximum transmit power is the maximum transmit power of the uplink communication signal based on the terminal capability. That is, the parameter of the perception offset is added to the upper limit and lower limit of the maximum transmit power of the uplink communication signal, so that the obtained upper limit and lower limit can better adapt to the uplink perception signal, so that the transmit power margin of the uplink perception signal is more accurate.

[0087] In a possible implementation, the upper limit value of the maximum transmit power of the uplink perception signal is determined based on the perception offset, the first parameter and the second parameter, and the minimum value of the first parameter and the second parameter is the upper limit value of the maximum transmit power of the uplink communication signal;

[0088] The lower limit of the maximum transmit power of the uplink perception signal is determined based on the perception offset, the third parameter and the fourth parameter, and the minimum value of the third parameter and the fourth parameter is the lower limit of the maximum transmit power of the uplink communication signal.

[0089] That is, in the definition formula of the maximum transmit power of the uplink communication signal, a perception-related perception offset is added to the parameters therein, for example:

[0090]

[0091] Among them, the parameter ΔT Sensing is the perception offset, which is determined based on the parameters of the uplink perception signal, the perception target or the perception area. The first parameter is or P Powerclass -ΔP Powerclass ; The second parameter is or P Powerclass -ΔP Powerclass The other one in the above formula can be parameter P Powerclass -ΔP Powerclass Plus a perception offset. The third parameter is and (P Powerclass -ΔP Powerclass )-max(max(MPR+ΔMPR,A_MPR)+ΔT IB +ΔT C +ΔT RxSRS , P_MPR), the fourth parameter is and (P Powerclass -

[0092] ΔP Powerclass )-max(max(MPR+ΔMPR,A MPR )+ΔT IB +ΔT C +ΔT RxSRS ,P MPR ) in another one. As shown in the above formula, it can be parameter (P Powerclass -ΔP Powerclass )-max(max(MPR+ΔMPR,A MPR )+ΔT IB +ΔT C +ΔT RxSRS ,P MPR) plus a perception offset. In this way, even if the remaining parameters are parameters of the uplink communication signal, the terminal can compensate for the difference between the reference path loss of the uplink perception signal and the reference path loss of the uplink communication signal through the perception offset, so that the determined uplink value and the lower limit value are more adaptable to the uplink perception signal, so that the maximum transmit power of the uplink perception signal determined based on the upper limit value and the lower limit value can be further made more accurate, so that the transmit power margin of the uplink perception signal is more accurate.

[0093] The perceptual offset satisfies at least one of the following:

[0094] Parameter ΔT Sensing Configured by the base station, for example, can be configured through RRC or MAC or PDCCH or PDSCH.

[0095] Or the parameter ΔT Sensing Can be predefined.

[0096] Or the parameter ΔT Sensing It can be recommended by the core network (eg, perception control unit).

[0097] ΔT Sensing It may be related to the waveform and modulation method of the uplink sensing signal.

[0098] ΔT Sensing It may be related to the frequency band, bandwidth, and duty cycle of the uplink sensing signal.

[0099] ΔT Sensing Can be related to the type of perceived target. For example: Different types of perceived targets, ΔT Sensing For example, for the two sensing targets, drone and car, ΔT Sensing different.

[0100] ΔT Sensing Can be related to the perception service. For example: different perception services, ΔT Sensing For example, for low-altitude detection and smart transportation, ΔT Sensing different.

[0101] ΔT Sensing It can be related to the RCS of the perceived target. For example: the smaller the RCS of the perceived target, the greater the ΔT Sensing The bigger.

[0102] ΔT Sensing Can be related to the perception area. For example: The larger the perception area, the larger ΔT Sensing The bigger.

[0103] ΔT SensingIt can be related to the distance between the sensing sending and receiving nodes. For example, the larger the distance between the sensing sending and receiving nodes, the greater the ΔT Sensing The bigger.

[0104] The UE needs to report to the base station the maximum distance between the sensing transmitting and receiving nodes that it supports.

[0105] In addition, the UE needs to report the maximum sensing area range supported by the UE to the base station. For example, the maximum sensing area range of the UE can be represented by the sensing angle supported by the UE and the corresponding maximum distance at the angle.

[0106] In a possible implementation, in method 1, the upper limit and lower limit of the maximum transmit power of the uplink perception signal can be determined only by the perception offset, or the upper limit and lower limit of the maximum transmit power of the uplink perception signal can be determined by the perception offset and other perception signal transmission parameters, such as the parameters in the formula in the above method 1. It can be the configured maximum transmit power of the uplink sensing signal or the configured maximum transmit power of the uplink communication signal. The description is not repeated here.

[0107] Mode 2: The upper limit value of the uplink perception signal is determined based on the upper limit value of the uplink communication signal and the perception offset;

[0108] The lower limit value of the uplink perception signal is determined based on the lower limit value of the uplink communication signal and the perception offset.

[0109] That is, the sensing offset is added to the upper and lower limits of the maximum transmission power of the uplink communication signal. As shown below:

[0110]

[0111] It should be noted that the description of the perceptual offset may refer to the description in the first method, and the embodiments of the present disclosure will not be repeated here.

[0112] The above is a description of the maximum transmit power of the uplink perception signal. After determining the maximum transmit power of the uplink perception signal, the terminal can determine the transmit power margin based on the maximum transmit power of the uplink perception signal. The following will describe a method for determining the transmit power margin.

[0113] In some embodiments, when it is determined to send the first indication information and to send the first uplink perception signal, the transmit power margin is determined based on the actual transmit power of the first uplink perception signal.

[0114] In some further embodiments, when it is determined to send the first indication information, the transmit power margin is determined based on the transmit power configured corresponding to the second uplink perception signal.

[0115] That is, a new type of transmit power margin reporting method is added, which is used for reporting the transmit power margin of the uplink perception signal. The transmit power margin of the uplink perception signal is equal to the maximum transmit power of the uplink perception signal minus the actual transmit power of the uplink perception signal based on the path loss estimation. The transmit power margin of the uplink perception signal can be calculated based on the actual uplink perception signal, for example, determined by the actual transmit power of the first uplink perception signal, or calculated by a reference uplink perception signal, for example, determined by the second uplink perception signal.

[0116] For the first uplink perception signal, the first uplink perception signal is an uplink perception signal that is determined to be transmitted when the first indication information is determined to be transmitted. In this way, the transmit power margin of the uplink perception signal is equal to the maximum transmit power of the first uplink perception signal minus the actual transmit power of the first uplink perception signal estimated based on the path loss.

[0117] For the second uplink perception signal, the second uplink perception signal may be any signal to be sent or a designated signal or a default signal, and the second uplink perception signal may be an uplink perception signal with a resource ID of 0 under the uplink bandwidth part (BWP) configuration.

[0118] In addition, when the transmit power margin is calculated based on the second uplink perception signal, the parameters MPR, A_MPR and P_MPR in the above formula are all equal to 0. In addition, the configured high-level parameters in the calculation process of the actual transmit power of the uplink perception signal estimated based on the path loss information are the configuration parameters corresponding to the uplink perception signal with a resource ID of 0 under the uplink BWP configuration.

[0119] In a possible implementation, when reporting the transmit power margin, the terminal needs to report the relaxation amount and the sensing offset of the second transmit power to the base station, so that the base station can determine the maximum transmit power of the uplink sensing signal based on this for better scheduling.

[0120] After determining the transmit power margin, the terminal may report the first indication information based on the parameters configured by the base station through high-layer signaling. For example, the terminal may receive the second indication information (sent by the base station or sent by the core network element), and the second indication information is used to configure at least one of the following parameters:

[0121] Reporting period of transmit power margin;

[0122] The reporting prohibition time of the transmit power margin;

[0123] The path loss change threshold that triggers the terminal to report the transmit power margin;

[0124] An indication of whether to report a maximum power control reduction amount of the second maximum transmit power;

[0125] an indication of whether to report a relaxation amount of the second maximum transmit power;

[0126] Indication of whether to report the sense offset.

[0127] The second indication information may be configured by the base station to the terminal through RRC or MAC CE, or may be recommended by a core network unit (sensing function, SF) to the base station, and then configured by the base station to the terminal.

[0128] In a possible implementation manner, the terminal sends the first indication information based on a preset condition, where the preset condition includes at least one of the following:

[0129] Meeting the reporting period of transmit power margin;

[0130] The difference between the path loss at the current transmission time and the path loss at the last transmission time is greater than the path loss change threshold, and the transmission time is the time when the transmit power margin is sent;

[0131] The escalation ban period has ended.

[0132] The first indication information may be reported to the base station via MAC CE or RRC or PUCCH or PUSCH. Two schemes for reporting the first indication information via MAC CE are described below.

[0133] Solution 1: The MAC CE includes reporting parameters, and the reporting parameters include at least one of the following:

[0134] Transmit power margin, maximum transmit power, indication of whether to report the maximum reduction of the terminal transmit power power control, indication of whether to report the relaxation of the second maximum transmit power, indication of whether to report the perception offset, maximum reduction of the power control of the second maximum transmit power, relaxation of the second maximum transmit power, perception offset. In this way, when reporting the transmit power margin through MAC CE, other reporting parameters can also be reported, which can not only help the base station determine the maximum transmit power of the uplink perception signal for better scheduling, but also save fields.

[0135] For example, Figure 3 As shown, the MAC CE for the transmit power headroom of the uplink perception signal includes reporting parameters, and the reporting parameters include the uplink perception signal transmit power headroom PH (Type 4) and the maximum transmit power of the uplink perception signal In addition, the MAC CE also includes whether to report the maximum power control reduction P_MPR of the second maximum transmit power or the relaxation amount of the second maximum transmit power. Instructions (such as Figure 3The offset indicator is a flag indicating whether to report the perceived offset ΔT. Sensing When P indicates that P_MPR or relaxation exists, or Offsetindicator indicates that a perception offset exists, the MAC CE also includes a relaxation of the second maximum transmit power. Or P_MPR, and / or perceived offset ΔT Sensing .

[0136] Solution 2: MAC CE also includes an uplink sensing signal resource identifier or a beam identifier. One uplink sensing signal resource identifier or one beam identifier corresponds to a group of reporting parameters.

[0137] That is, the transmit power margin can be reported with the uplink perception signal resource or beam as the granularity. A MAC CE for reporting the transmit power margin may include at least one of the power-related parameters of multiple uplink perception signals: uplink perception signal resource set ID, uplink perception signal resource ID, uplink perception signal transmit power margin, uplink perception signal maximum transmit power, whether to report the second maximum transmit power maximum reduction P_MPR or the second maximum transmit power relaxation Indication of whether to report the perception offset ΔT Sensing Indication of the second maximum transmit power relaxation amount Or the maximum power control reduction amount P_MPR of the second maximum transmission power, and / or the perception offset ΔT Sensing That is, based on solution 1, in one MAC CE, one uplink perception signal resource identifier or one beam identifier corresponds to a set of reporting parameters (it should be understood that the reporting parameters include at least one of the above parameters).

[0138] Exemplary, combined Figure 3 ,like Figure 4 As shown, the MAC CE includes an uplink sensing signal resource set ID and an uplink sensing signal resource ID. In addition, an uplink sensing signal resource ID corresponds to a set of reporting parameters in solution 1 (ie, P, Offsetindicator, etc.), a MAC CE includes multiple uplink perception signal resource set IDs, uplink perception signal resource IDs, and their corresponding multiple groups of reporting parameters.

[0139] The above is a reporting method for the first indication information. Below, the configuration method of two parameters (i.e., the fifth parameter) for determining the maximum transmit power of the uplink perception signal will be described. The fifth parameter includes the maximum power control reduction amount and / or the perception offset of the second maximum transmit power.

[0140] In some embodiments, the terminal sends third indication information to the base station and / or the core network element, and the third indication information is used to indicate the target parameter, and the target parameter includes the maximum power control reduction amount and / or the perception offset of the second maximum transmit power. Optionally, the target parameter is predefined; or, the target parameter is configured by the base station; the target parameter is configured by the core network element; or the target parameter is determined by the terminal. The configuration process of the target parameter will be described below.

[0141] The sensing service is generally controlled by the core network unit (sensing function, SF), that is, the core network unit is more aware of the needs of the sensing service and the sensing transceiver nodes. Therefore, the relevant parameter configuration of the uplink sensing signal transmission power can be recommended or configured by the core network unit, so as to recommend or configure the parameter configuration that is more suitable for the sensing service. The following is the configuration process of the parameters related to the uplink sensing signal transmission power.

[0142] 1.1.1 A core network element (also referred to as a core network unit) recommends a power control maximum reduction amount P_MPR of a second maximum transmit power to a base station.

That is, the maximum power control reduction of the second maximum transmit power of the uplink perceived signal corresponding to each perceived service is the same, and the maximum power control reduction of the second maximum transmit power of the uplink perceived signal corresponding to different perceived services is different. In other words, each perceived service is associated with a maximum power control reduction of the second maximum transmit power perceived.

[0144] Alternatively, the core network unit may recommend the maximum power control reduction of the second maximum transmit power perceived to the base station based on the granularity of the sensing area. That is, the maximum power control reduction of the second maximum transmit power of the uplink sensing signal corresponding to one sensing area is the same, and the uplink sensing signals corresponding to different sensing areas have different maximum power control reductions of the second maximum transmit power. In other words, each sensing area is associated with a maximum power control reduction of the second maximum transmit power perceived.

[0145] Alternatively, the core network unit may recommend to the base station the maximum power control reduction of the second maximum transmit power perceived by the type of the perception target. That is, the maximum power control reduction of the second maximum transmit power of the uplink perception signal corresponding to the same perception target is the same, and the uplink perception signals corresponding to different types of perception targets have different maximum power control reductions of the second maximum transmit power. In other words, each perception target is associated with a maximum power control reduction of the second maximum transmit power perceived.

That is, the maximum reduction amount of the second maximum transmit power power control of the uplink perceived signal corresponding to the perceived target RCS in one interval is the same, and the maximum reduction amount of the second maximum transmit power power control of the uplink perceived signal corresponding to the perceived target RCS belonging to different intervals is different. In other words, each RCS interval is associated with a perceived maximum reduction amount of the second maximum transmit power power control.

[0148] 1.2 The base station configures the UE with a power control maximum reduction amount P_MPR of the second maximum transmit power.

[0149] The base station can configure the perceived second maximum transmit power control maximum reduction P_MPR to the UE via RRC or MAC or PDCCH or PDSCH. In addition, the P_MPR configured by the base station can be determined by the base station itself or recommended by the core network unit.

[0150] 1.3 The UE reports the perceived second maximum transmit power control maximum reduction P_MPR to the core network unit.

[0151] The UE can report the perceived second maximum transmit power control maximum reduction to the core network unit based on the perceived service granularity, so that the core network unit can determine whether the base station has adopted the P_MPR value recommended by itself, and if it is determined that the base station has not adopted the value recommended by itself, it can re-determine the P_MPR value recommended to the base station based on the value determined by the base station itself, so that the value is more accurate. In other words, each perceived service is associated with a perceived second maximum transmit power control maximum reduction.

[0226] The information transmission method provided by the embodiment of the present disclosure can be applied to Figure 1 A base station 102 is shown in the communication system. Figure 5 A flow chart of another information transmission method is shown, such as Figure 5 As shown, the information transmission method includes the following S501.

[0227] S501. A base station receives first indication information.

[0228] The first indication information is used to indicate the transmit power margin of the uplink perception signal.

[0229] Since the uplink perception signal is sent by the terminal and then received by the base station after being reflected by the perception target, the loss of the uplink perception signal is relatively large. Therefore, the transmission power margin of the uplink communication signal determined based on the path loss of the uplink communication signal is no longer suitable for the uplink perception signal. When reporting the transmission power margin, it is necessary to determine the transmission power margin suitable for the uplink perception signal. To this end, the terminal can determine the maximum transmission power and actual transmission power of the uplink perception signal, thereby determining the transmission power margin of the uplink perception signal and reporting it to the base station. After receiving the first indication information, the base station can obtain a more accurate transmission power margin and further improve the accuracy of base station scheduling.

[0230] It should be pointed out that for descriptions on the determination method and reporting method of the transmit power margin, reference may be made to the description on the terminal side, and the embodiments of the present disclosure will not be repeated here.

[0231] It is understandable that, in order to realize the above functions, the information transmission device includes hardware structures and / or software modules corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the algorithm steps of each example described in the embodiments of the present disclosure, the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of the present disclosure.

[0232] The embodiments of the present disclosure may divide the information transmission device into functional modules according to the above method embodiments. For example, each functional module may be divided corresponding to each function, or two or more functions may be integrated into one functional module. The above integrated modules may be implemented in the form of hardware or software. It should be noted that the division of modules in the embodiments of the present disclosure is schematic and is only a logical function division. There may be other division methods in actual implementation. The following is an example of dividing each functional module corresponding to each function.

[0233] Figure 6 is a schematic diagram of the structure of a communication device provided by an embodiment of the present disclosure, and the communication device can execute the information transmission method provided by the above method embodiment. Figure 6 As shown, the communication device includes: a sending unit 601.
