Detailed ways

The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

As a network-side device, the total transmission power of the smart repeater can be constant, or the smart repeater can always forward uplink/downlink at the maximum transmission power. Therefore, under different system bandwidths (which can be understood as the total bandwidth configured by the network side for the cell, which can be expressed in English as system bandwidth or system BW), the performance gain or power spectral density (PSD, Power Spectral Density) brought by the smart repeater is different. For example, as shown in Figure 2, assuming that the transmission power of the smart repeater is 400 watts (W), when the smart repeater works under the system bandwidth of 100 MHz, the PSD of the smart repeater uplink (referred to as PSD_1 in the subsequent description) is 4 watts per MHz (W/MHz) (PSD_1 = 400/100 = 4w/MHz); when the smart repeater works under the system bandwidth of 10MHz, the PSD of the smart repeater uplink (referred to as PSD_2 in the subsequent description) is 40w/MHz (PSD_2 = 400/10 = 40w/MHz). It can be seen that PSD_2 can provide an additional 10 decibels (dB) gain compared to PSD_1. In other words, when the working bandwidth (actual bandwidth or actual BW) of the smart repeater (also known as transmission bandwidth or actual bandwidth) is adjusted from 100MHz to 10MHz, the smart repeater has an amplification gain of 10dB.

As can be seen from Figure 2, if the intelligent repeater forwards according to the system bandwidth, the PSD is low (such as PSD_1), but the actual working bandwidth used by the UE is limited; if the intelligent repeater forwards in a fixed PSD manner, a lot of power will be wasted. Therefore, if the intelligent repeater can determine the actual working bandwidth of the UE, it can concentrate all the power on the actual working bandwidth of the UE, thereby obtaining additional gain (such as PSD_2); and after the gain of the intelligent repeater is improved, the UE's transmission power can be reduced, thereby achieving the purpose of energy saving. For example, as shown in Figure 3, when the base station and the UE perform uplink transmission based on the forwarding of the intelligent repeater, since the uplink transmission power of the intelligent repeater needs to reach a specific value to ensure that the base station can receive the uplink data of the UE, if the power of the intelligent repeater can be fully utilized, that is, the amplification gain of the intelligent repeater for uplink forwarding is increased, the uplink transmission power of the UE can be effectively reduced, thereby achieving the purpose of energy saving.

However, the intelligent repeater in the related art cannot adaptively sense the working bandwidth, that is, the intelligent repeater cannot know the actual working bandwidth of the UE, for example, it cannot judge the actual working bandwidth (such as the actual bandwidth shown in 2) based on the input power and bandwidth; or, the intelligent repeater can obtain bandwidth through specific means, but the forwarding speed is set to be fast (such as nanosecond forwarding speed), so it is impossible to adjust the amplification gain while forwarding the radio frequency. Therefore, the intelligent repeater needs an additional mechanism to determine the forwarding gain and/or the actual working bandwidth of the UE; in other words, it is necessary to introduce a variable working bandwidth of the intelligent repeater so that the intelligent repeater can obtain additional power or PSD gain.

In actual application, if the above problems are solved, the intelligent repeater can adjust the working bandwidth and obtain additional amplification gain. Then the network side needs to further adjust the UE's transmit power to reduce the UE's transmit power and achieve energy saving, while increasing the UE's transmission bandwidth and transmission rate.

The following analyzes several ways to reduce the UE uplink transmission power.

In actual application, as shown in Figure 4, the UE can measure the downlink PL and calculate the UE's uplink transmit power Txp by the following formula:
Txp＝P0+alpha*PL+10*log ₁₀ (2 ^μ *M _RB )+other parameters (1)

Among them, P0 represents the UE-specific power; alpha represents the compensation factor of the downlink path loss. If alpha is equal to 1, alpha*PL represents the full path loss compensation. If alpha is less than 1, alpha*PL represents the partial path loss compensation; M _RB represents the number of resource blocks (RB), and μ is a subcarrier spacing (SCS) related configuration parameter; other parameters may include power control adjustment parameters, etc.; PL represents the downlink path loss, which can be calculated by the following formula:
PL＝PL1+gain_smart+PL2 (2)

Among them, PL1 represents the path loss between the base station and the smart repeater; gain_smart represents the gain of the smart repeater (which can be expressed as gain in English); PL2 represents the path loss between the smart repeater and the UE.

In practical applications, considering the additional gain brought by the intelligent repeater due to bandwidth compression during uplink transmission, the new uplink transmit power Txp1 of the UE can be calculated by the following formula:
Txp1＝P0+alpha*PL+10*log ₁₀ (2 ^μ *M _RB )+other parameters-gain_1 (3)

Wherein, gain_1 represents the gain increased by the smart repeater, which can also be called additional gain (in English, it can be expressed as Additional gain); it can be seen that by increasing the amplification gain of the smart repeater, the UE's transmission power can be reduced. gain_1 can be calculated by formula (4) or formula (5):
gain_1＝L2DB((Txp/actual BW)/(Txp/system BW)) (4)
gain_1＝L2DB(system BW/actual BW) (5)

Among them, actual BW represents the actual working bandwidth of UE; system BW represents the system bandwidth.

Combining formula (1) to formula (5), it can be seen that the following three methods can be considered to reduce the uplink transmission power of the UE:

Mode 1: The base station instructs the intelligent repeater to transmit uplink bandwidth and gain;

Method 2: subtract gain_1 from P0, i.e. the base station indicates or updates the UE's P0; or, use -gain_1 as an explicit offset The amount (which can be expressed as offset in English) means that the base station directly instructs the UE to reduce the transmit power, or reduces the transmit power through closed-loop power control;

Mode 3, reducing gain_1 from the relevant value or measurement result of PL, that is, the base station instructs the intelligent repeater to increase the gain in the downlink direction, thereby reducing PL.

In practical applications, taking into account the downlink path loss PL, it can also be calculated using the following formula:
PL＝Txp _Gnb -P _{UE_RX} ＝PL1+gain_smart+PL2 (6)

Among them, Txp_Gnb represents the base station transmission power; P _{UE_RX} represents the UE reception power.

Therefore, the following two methods can be considered to implement method 3 above:

Mode 3-1: When the smart repeater has gain margin, the base station directly instructs the smart repeater to increase the gain in the downlink direction (i.e., increase gain_smart);

Mode 3-2: The base station increases the gain of the intelligent repeater for downlink forwarding by adjusting the working bandwidth of the intelligent repeater for downlink forwarding.

Based on this, in various embodiments of the present application, on the one hand, corresponding to the above-mentioned method 1, the first network device (such as a base station, etc.) can indicate the working bandwidth and/or power on the first time domain resource for uplink transmission to the second network device (such as an intelligent repeater, etc.), so that the second network device obtains additional uplink power gain, that is, improves the amplification gain of the second network device for uplink forwarding, and fully utilizes the power of the second network device, thereby effectively reducing the uplink transmission power of the terminal; on the other hand, corresponding to the above-mentioned method 3, the first network device can indicate to the second network device to adjust the transmission power and/or working bandwidth for downlink transmission, so that the second network device obtains additional downlink power gain, that is, improves the amplification gain of the second network device for downlink forwarding, and fully utilizes the power of the second network device, thereby reducing the downlink PL measured by the terminal, based on the correlation between the uplink transmission power of the terminal and the downlink PL measured by the terminal (that is, formula (1)), thereby effectively reducing the uplink transmission power of the terminal; at the same time, corresponding to the above-mentioned method 2, the first network device can reduce the uplink transmission power of the terminal by indicating the terminal to adjust the transmission power. In this way, by reducing the uplink transmission power of the terminal, the purpose of energy saving can be achieved, that is, the power consumption of the terminal can be reduced, and the transmission bandwidth and transmission rate of the terminal can be increased, thereby improving the performance of the terminal.

The embodiment of the present application provides an information transmission method, which is applied to a first network device (such as a base station), and the method includes:

In actual application, the first information is used for uplink transmission of the second network device, which can also be understood as the first information being used for uplink forwarding of the second network device, that is, the first information is used for the second network device to forward the signal and/or channel of the at least one terminal to the first network device; in other words, the first time domain resource is the time domain resource used by the second network device for uplink transmission or uplink forwarding.

In actual application, the first network device may include a base station, etc. The second network device may at least have the functions of relaying and forwarding, and may specifically include an intelligent repeater, or a network controlled repeater (NCR, Network Controlled Repeater), or a repeater (which can be expressed as Repeater in English), or a base station, or a relay device, etc. The specific type of the second network device may be determined according to demand.

At the same time, the first time domain resource can be associated with a backhaul link (which can be expressed as Backhaul link in English); or, the first time domain resource can be associated with at least one transmission configuration of the backhaul link. Among them, the access link is the link between the second network device and the terminal, and the backhaul link is the link between the second network device and the first network device. The access link and The transmission configuration of the backhaul link may include beam information, such as a beam identifier (such as an ID), etc.; or may include transmission configuration indication (TCI, Transmission Configuration Indicator) state (expressed as state in English) information, spatial relationship information (such as beam direction, etc.), spatial filtering (expressed as spatial filter in English) information (such as the beam direction sent by the uplink terminal, etc.); the transmission configuration of the access link and the backhaul link can be determined specifically according to demand.

Based on this, in one embodiment, the first time domain resource may satisfy at least one of the following conditions:

being associated with an access link or at least one transmission configuration of said access link;

Being associated with a backhaul link or at least one transmission configuration of the backhaul link.

In actual application, the working bandwidth indicated by the first information can be understood as the transmission bandwidth or actual bandwidth of the second network device for uplink transmission on the first time domain resource; in other words, after the second network device receives the first information, in the process of forwarding the signal and/or channel of the at least one terminal to the first network device according to the first information, the second network device only amplifies the signal and/or channel within the working bandwidth, and does not amplify the signal and/or channel outside the working bandwidth.

In actual application, after receiving the first information, the second network device can determine the additional uplink power gain (which can be expressed as Additional gain in English) obtained by the second network device during uplink transmission or uplink forwarding according to the working bandwidth and/or power on the first time domain resource indicated by the first information. Exemplarily, when the first information indicates the working bandwidth on the first time domain resource, the second network device can use the above formula (4) or formula (5) to calculate the additional uplink power gain.

In actual application, it can be understood that the implementation principle of the first network device reducing the uplink transmission power of the terminal by sending the first information to the second network device is the same as the implementation principle of the above-mentioned method 1, that is, by compressing the transmission bandwidth of the second network device during uplink forwarding, or by increasing the transmission power of the second network device during uplink forwarding, the second network device obtains additional uplink power gain, that is, the amplification gain of the second network device for uplink forwarding is increased, and the power of the second network device is fully utilized, thereby effectively reducing the uplink transmission power of the terminal and achieving the purpose of energy saving.

In actual application, corresponding to an implementation method of the above-mentioned method 2, the second information may include an explicit offset, that is, the second information may include an adjustment value of the transmit power, and the adjustment value of the transmit power may correspond to the additional power gain obtained by the second network device, that is, the increased amplification gain when the second network device performs uplink forwarding, that is, the gain equivalent to the reduction of the uplink working bandwidth by the second network device according to the first information.

In actual application, corresponding to another implementation method of the above-mentioned method 2, the second information may include TPC-related information, so that the at least one terminal can reduce the transmission power through closed-loop power control according to the second information.

In practical application, considering that the closed-loop TPC in the related technology gives priority to reducing power, a new closed-loop power value, such as -3dB, can be introduced into the TPC-related information; in other words, the TPC-related information can include a new closed-loop power value, and after each of the at least one terminal receives the second information, the new closed-loop power value can be added to the local TCP table. In the grid, the TCP table is updated, and the updated TCP table can be used to adjust the transmission power.

In actual application, the TPC-related information may include a new TCP table, which may contain closed-loop power values such as 1, 0, -1, and -3 (the specific closed-loop power values contained in the table can be set according to requirements); after each terminal in the at least one terminal receives the second information, it can use the new TCP table to adjust the transmission power.

In actual application, the TPC-related information may include flip indication information for one or more closed-loop power values in the local TCP table of the terminal, and the flip indication information may be used to activate or enable (expressed as enable in English) the corresponding closed-loop power value, or may be used to change the terminal's understanding of the corresponding closed-loop power value. Exemplarily, the flip indication information may enable the terminal to understand the corresponding closed-loop power value as the original value multiplied by -1, such as changing the closed-loop power value -1 to +1, 0 to 0, +3 to -3, etc. When the closed-loop power value +3 is changed to -3, when performing closed-loop power control, the terminal changes from increasing the power by 3dB to reducing the power by 3dB.

In actual application, corresponding to the third implementation method of the above-mentioned method 2, the second information may include a terminal-specific power P0, and the P0 may be a new P0, that is, the second information may directly include the new P0; or, the P0 may be one of the multiple P0s pre-configured by the first network device (for example, configured through RRC) to the terminal; after each of the at least one terminal receives the second information, it can use the P0 in the second information to adjust its own local P0 (for example, update P0, or select a new P0 locally according to the second information), and use the adjusted P0 to adjust the transmission power.

In actual application, the first network device may send the second information to the at least one terminal via RRC signaling, such as sending a new P0 via RRC signaling.

Based on this, in one embodiment, sending the second information to at least one terminal may include:

Sending RRC signaling to the at least one terminal, where the RRC signaling includes the second information.

In actual application, the first network device may send the second information to the at least one terminal via DCI, such as sending a new P0 via DCI.

Based on this, in one embodiment, sending the second information to at least one terminal may include:

Sending a DCI to the at least one terminal, where the DCI includes the second information.

In actual application, the first network device can send the second information to the at least one terminal through MAC CE, such as sending a new P0 through MAC CE.

Based on this, in one embodiment, sending the second information to at least one terminal may include:

Send a MAC CE to the at least one terminal, wherein the MAC CE includes the second information.

In actual application, the first network device can configure multiple sets of configuration parameters (i.e., multiple second information) to each terminal in the at least one terminal through RRC signaling or other means. When the second information needs to be sent to the at least one terminal (i.e., when the second information needs to be adjusted), the first network device can indicate the adjusted second information to the at least one terminal through SRI. For example, the first network device can configure multiple P0s for each terminal in the at least one terminal through RRC, and can indicate the adjusted P0 through SRI, so as to achieve the effect of reducing P0 and thus reducing the transmit power of the terminal.

Based on this, in one embodiment, sending the second information to at least one terminal may include:

An SRI is sent to the at least one terminal, where the SRI is associated with the second information.

After receiving the SRI, each terminal in the at least one terminal may determine second information associated with the SRI from locally stored information, and then adjust the transmission power using the determined second information.

In actual application, the third information is used for downlink transmission of the second network device, and can also be understood as the third information being used for downlink forwarding of the second network device, that is, the third information is used for the second network device to forward the signal and/or channel of the first network device to the at least one terminal; in other words, the adjusted working bandwidth indicated by the third information can be understood as the transmission bandwidth or actual bandwidth of the second network device when performing downlink transmission, and the adjusted transmission power indicated by the third information can be understood as the transmission power of the second network device when performing downlink transmission.

In actual application, the second network device has a maximum gain limit (which can also be understood as a maximum transmit power limit). When the actual amplification gain of the second network device is less than the maximum gain, it can be considered that the second network device has a gain margin (which can also be understood as a power margin); or, when the transmit power of the second network device is less than the maximum transmit power, it can also be considered that the second network device has a gain margin. The second network device can report the current amplification gain or the current gain margin to the first network device, so that the first network device can determine whether the second network device still has a gain margin or a power margin, thereby determining the content indicated by the third information according to whether the second network device has a gain margin. Wherein, in the case where the second network device has a gain margin, the third information can indicate to increase the downlink forwarding gain of the second network device, that is, to increase the downlink transmit power, or can indicate to use a larger working bandwidth, so as to reduce the downlink PL measured by the terminal, and then reduce the uplink transmit power of the terminal. In the case where the gain of the second network device is insufficient, the third information can indicate to reduce the downlink working bandwidth of the second network device, so as to increase the downlink forwarding gain of the second network device.

Specifically, in actual application, when the third information indicates to reduce the downlink working bandwidth of the second network device, the third information may instruct the second network device to directly reduce the downlink partial bandwidth (BWP, BandWidth Part), thereby reducing the The downlink forwarding bandwidth of the second network device; wherein the third information may include the reduced BWP or the reduced value of the BWP. Alternatively, the third information may indicate at least one adjusted downlink working bandwidth (which may be a small bandwidth, and the specific value of the bandwidth may be determined according to demand) to the second network device, and each adjusted downlink working bandwidth may correspond to a different downlink forwarding gain. Alternatively, the third information may indicate at least one adjusted downlink working bandwidth to the second network device, and instruct the second network device to directly reduce the downlink BWP. Here, the specific method of reducing the downlink working bandwidth of the second network device indicated by the third information may be determined according to demand.

In actual application, when the third information indicates at least one adjusted downlink working bandwidth to the second network device, and each adjusted downlink working bandwidth corresponds to a different downlink forwarding gain, the first network device needs to configure the at least one terminal with an additional reference signal (which can be expressed as Reference Signal, RS) corresponding to each adjusted downlink working bandwidth. The reference signal corresponding to each adjusted downlink working bandwidth may include a channel state information reference signal (CSI-RS, Channel State Information-Reference Signal), etc., such as a CSI-RS with a small bandwidth (the specific value of the bandwidth can be determined according to demand) (which can correspond to forwarding of a small bandwidth), etc.; the reference signal can be used to measure the downlink PL (so the reference signal can be expressed as PL-RS).

Based on this, in one embodiment, when the third information indicates adjusting the working bandwidth, the method may further include:

Sending fourth information to the at least one terminal, the fourth information indicating at least one reference signal-related configuration, the at least one reference signal-related configuration being associated with the working bandwidth corresponding to the third information, and the at least one reference signal being used to measure a downlink PL.

Among them, the configuration related to at least one reference signal is associated with the working bandwidth corresponding to the third information, which can be understood as when the third information indicates at least one adjusted downlink working bandwidth to the second network device, and each adjusted downlink working bandwidth corresponds to a different downlink forwarding gain, then each reference signal-related configuration corresponds to a downlink working bandwidth, that is, corresponds to a downlink forwarding gain; in other words, each reference signal is used to send and forward data on the corresponding downlink working bandwidth.

In actual application, the first network device may send the third information to the second network device via RRC signaling.

Based on this, in one embodiment, sending the third information to the second network device may include:

Send RRC signaling to the second network device, where the RRC signaling includes the third information.

In actual application, the first network device may send the third information to the second network device via DCI.

Based on this, in one embodiment, sending the third information to the second network device may include:

In actual application, the first network device can send the third information to the second network device via MAC CE.

Based on this, in one embodiment, sending the third information to the second network device may include:

In actual application, for all terminals with uplink transmission requirements, the first network device can be grouped according to the beam corresponding to each terminal in all the terminals, and each terminal group contains at least one terminal; for each terminal group, the first network device can determine the actual working bandwidth of each terminal in the terminal group, and calculate the additional uplink power gain (i.e., gain_1) that the second network device can obtain in the downlink based on the determined actual working bandwidth, and the first network device can adjust the downlink amplification gain of the second network device based on the calculated gain_1, that is, determine the third information; or, the first network device can adjust the P0 of the target user based on the calculated gain_1, that is, determine the second information corresponding to at least one terminal contained in the terminal group; in this way, the uplink transmission power of at least one terminal in the terminal group can be reduced.

The information transmission method provided by the embodiment of the present application is as follows: a first network device sends first information to a second network device, and/or sends second information to at least one terminal, and/or sends third information to the second network device; the second network device receives the first information sent by the first network device, and/or receives the third information sent by the first network device; the terminal receives the second information sent by the first network device, and uses the second information to adjust the transmission power; wherein the first information indicates the working bandwidth and/or power on the first time domain resource, and the first information is used for uplink transmission of the second network device; the second information indicates adjustment of the transmission power; the third information indicates adjustment of the transmission power and/or working bandwidth, and the third information is used for downlink transmission of the second network device; the second network device can be used to forward signals and/or channels of the first network device and/or the terminal. The solution provided in the embodiment of the present application, on the one hand, corresponding to the above-mentioned method 1, the first network device (such as a base station, etc.) can indicate the working bandwidth and/or power on the first time domain resource for uplink transmission to the second network device (such as an intelligent repeater, etc.), so that the second network device obtains additional uplink power gain, that is, improves the amplification gain of the second network device for uplink forwarding, and fully utilizes the power of the second network device, thereby effectively reducing the uplink transmission power of the terminal; on the other hand, corresponding to the above-mentioned method 3, the first network device can indicate to the second network device to adjust the transmission power and/or working bandwidth for downlink transmission, so that the second network device obtains additional downlink power gain, that is, improves the amplification gain of the second network device for downlink forwarding, and fully utilizes the power of the second network device, thereby reducing the downlink PL measured by the terminal, based on the correlation between the uplink transmission power of the terminal and the downlink PL measured by the terminal (that is, formula (1)), thereby effectively reducing the uplink transmission power of the terminal; at the same time, corresponding to the above-mentioned method 2, the first network device can reduce the uplink transmission power of the terminal by indicating the terminal to adjust the transmission power. In this way, by reducing the uplink transmission power of the terminal, the purpose of energy saving can be achieved, that is, the power consumption of the terminal can be reduced, and the transmission bandwidth and transmission rate of the terminal can be increased, thereby improving the performance of the terminal.

The present application is described in further detail below in conjunction with application examples.

In this application example, the first network device includes a base station, the second network device includes a smart repeater, called a Smart repeater; and the terminal is called a UE.

In this application example, as shown in FIG7 , the uplink forwarding gain of the Smart repeater can be improved through the interaction between the base station and the Smart repeater. Specifically, the base station can inform the Smart repeater of the actual BW of uplink forwarding (such as the minimum continuous bandwidth corresponding to the uplink transmission bandwidth of multiple UEs), that is, the base station can send first information to the Smart repeater, and the first information can include the actual BW. The Smart repeater can calculate the additional uplink power gain gain_1 according to the system BW and the actual BW using the above formula (4) or formula (5), or the base station can configure gain_1 to the Smart repeater (that is, the first information can include gain_1). The Smart repeater can perform uplink forwarding at the corresponding time according to the BW indicated by the base station and the time of uplink forwarding (that is, the first information can also include the first time domain resource for uplink forwarding, such as a time slot, etc.), thereby fully utilizing the power of the Smart repeater, thereby effectively reducing the uplink transmission power of the UE.

In this application example, as shown in FIG7 , the uplink transmission power of the UE can be reduced on the UE side, that is, the base station can inform the corresponding UE or multiple UEs of gain_1, thereby reducing the transmission power of the UE. After the UE reduces the uplink transmission power according to gain_1, the Smart repeater can forward only on the configured actual BW and obtain additional transmission gain.

The following two implementation methods can be used to enable the base station to inform the corresponding UE or multiple UEs of gain_1, thereby reducing the transmission power of the UE:

Option 1: The base station instructs the UE to adjust the transmit power in a relatively dynamic manner.

Option 2: The base station uses a relatively semi-static indication method to instruct the UE to adjust the transmission power.

In this application example, option 1 above can be implemented in the following six ways:

Option 1-1, the base station instructs the UE to increase the uplink transmission power by offset, where offset = -gain_1; that is, the base station sends the second information to the UE, where the second information includes the adjustment value of the transmission power;

Option 1-2: the base station instructs the UE to reduce the transmit power through a TPC command; that is, the base station sends second information to the UE, where the second information includes TPC-related information;

Option 1-3, the base station configures P0 of the UE according to gain_1; that is, the base station sends second information to the UE, where the second information includes the UE-specific power P0;

Option 1-4: When the downlink gain of the Smart repeater can be increased, the base station instructs the Smart repeater to increase the downlink gain by gain_1, thereby reducing the PL obtained by the UE downlink measurement; that is, the base station sends the third information to the Smart repeater, and the third information includes gain_1 or the downlink transmission power corresponding to gain_1;

Option 1-5, when the downlink gain of the Smart repeater cannot be increased by gain_1, the base station instructs the Smart repeater to reduce the BW of downlink forwarding, thereby improving the downlink forwarding gain, and configures the corresponding PL-RS to the UE; that is, the base station sends the third information to the Smart repeater, the third information instructs the Smart repeater to reduce the BW of downlink forwarding, and sends the fourth information to the UE, the fourth information includes the configuration related to the PL-RS;

Option 1-6: The base station instructs the Smart Repeater to appropriately adjust the downlink forwarding BW and the downlink amplification gain, that is, to reduce the uplink transmission power of the UE by combining Option 1-4 and Option 1-5.

In this application example, when implementing option 2 above, the base station can group the UEs according to the beams to which they are located, and determine the actual BW corresponding to each group of UEs; the base station can calculate the additional uplink gain gain_1 of the Smart repeater according to the determined actual BW, and can adjust the downlink amplification gain corresponding to the Smart repeater according to gain_1, that is, determine the third information according to gain_1; or, the base station can adjust the P0 of the target user according to gain_1, that is, determine the second information according to gain_1, thereby reducing the uplink transmission power of the UE.

The solution provided by this application example has the following advantages:

1) The base station configures the Smart repeater to transmit or forward in a specified time slot (i.e., the first time domain resource mentioned above) with a certain bandwidth (i.e., the working bandwidth on the first time domain resource), which is smaller than the system bandwidth of the Smart repeater, so that the Smart repeater can obtain additional uplink power gain (i.e., amplification gain), thereby reducing the uplink transmission power of the UE, thereby achieving the effect of UE energy saving.

2) The base station can reduce the downlink PL measured by the UE by adjusting the downlink bandwidth of the Smart repeater and/or increasing the downlink transmission gain of the Smart repeater, thereby reducing the uplink transmission power of the UE and achieving UE energy saving.

3) The base station can instruct the UE to modify the P0 parameter value of the UE, thereby reducing the uplink transmission power of the UE and achieving the effect of UE energy saving.
