[0051] A terminal may also be called user equipment (UE), terminal equipment, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device, etc.

[0052] The network side device 12 may include an access network device or a core network device, wherein the access network device may also be referred to as a radio access network (RAN) device, a radio access network function or a radio access network unit. The access network device may include a base station, a wireless local area network (WLAN) access point (AS) or a wireless fidelity (WiFi) node, etc. Among them, the base station may be referred to as a Node B (NB), an evolved Node B (eNB), a next generation Node B (gNB), a New Radio Node B (NR Node B), an access point, a Relay Base Station (RBS), a Serving Base Station (SBS), a Base Transceiver Station (BTS), a radio base station, a radio transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a Home Node B (HNB), a Home Evolved Node B (home evolved Node B), a Transmission Reception Point (TRP) or other appropriate terms in the field. As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0053] To facilitate understanding of the embodiments of the present application, the network control forwarding node related to the present application is described.

[0054] In some scenarios, in order to expand the coverage of the cell, a network controlled forwarding node, such as a network controlled repeater (NCR), is introduced. The network controlled forwarding node can be used, for example, to receive, amplify and forward downlink signals from the base station, so that the signal strength reaching the UE is increased; receive, amplify and forward uplink signals from the UE, so that the strength of the uplink signal from the UE to the upstream network side device is increased.

[0055] NCR can accept control from upstream network side equipment, that is, the network side equipment can control the transmission parameters of NCR, such as the switch and transmission beam of NCR, so as to improve the working efficiency of the amplifier and reduce interference. Figure 2 shows a logical structure of NCR, such as Figure 2 As shown, the NCR may include an NCR terminal (NCR Mobile Termination, NCR-MT) module and an NCR forwarding (NCR Forwarding, NCR-FWD) module. The NCR-MT module may establish a connection with an upstream base station, and the base station may interact with the NCR-FWD module through the NCR-MT module to control signaling, for example, it may indicate to the NCR the sending or receiving related parameters of the NCR-FWD module for the NCR.

[0056] For example, the base station sends side control information (SCI) to the NCR node through the NCR-MT module of the NCR to control the uplink and downlink power / amplification factor, beam parameters, uplink and downlink configuration, etc. of the radio frequency (RF) module of the NCR.

[0057] The control link between the NCR-MT module and the base station is used to transmit side control information. There is a backhaul link (BH) between the NCR-FWD module and the base station, and an access link (Access Link) between the NCR-FWD module and the UE. The backhaul link and access link are used to forward wireless signals between the base station and the UE. The base station sends side control information to the NCR through the control link to control the forwarding behavior of the NCR-FWD module.

[0058] In the related art, there is a power control mechanism for the uplink transmission of the UE to the base station, which is used to control the uplink transmission power of the UE. The purpose of the uplink power control is to adjust the uplink transmission power of the UE so that the receiving power of the base station reaches an appropriate level to ensure the strength of the received signal. At the same time, it is to avoid the UE's uplink transmission power being too large, causing greater interference to neighboring cells and wasting the UE's power. For example, the UE calculates and determines the uplink transmission power based on the propagation path loss between the base station and the UE, the occupied spectrum width, the MCS, the coding rate, the target receiving power level set by the base station, and the power adjustment amount configured by the base station through the power control command. The base station generally does not perform dynamic power adjustment for downlink transmission to the UE. The base station determines the downlink channel quality between the base station and the UE and the size of the data block to be sent based on the UE's channel state information (CSI) report, allocates an appropriate amount of time-frequency resources, and selects appropriate transmission parameters (such as the number of spatial data streams, the modulation and coding scheme (MCS), the duration length, and the frequency range) so that the amount of information transmitted matches the amount of allocated time-frequency resources.

[0059] After the introduction of NCR, when the NCR-FWD module of NCR forwards the uplink and downlink wireless signals between the base station and the UE, the transmission power of the forwarded uplink and downlink signals can be adjusted by adjusting the amplification factor of the forwarded signals.

[0060] However, in actual applications, there is a scenario where an NCR provides uplink and downlink forwarding services for a base station and multiple UEs served by the base station, such as Figure 3 As shown in the figure, an NCR provides uplink and downlink forwarding services for a base station and three UEs (including UE1, UE2 and UE3). In this case, different wireless links between a base station and multiple UEs are involved, and the interaction between the forwarding power adjustment of the NCR and the power adjustment of the base station or UE is involved. Therefore, the power control algorithm on the wireless link between the base station and the UE is not suitable for the forwarding power control of the NCR. How to implement the forwarding power control on the NCR is an urgent problem to be solved.

[0061] The forwarding power control method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0062] Figure 4 is a schematic interactive diagram of a forwarding power control method 400 according to an embodiment of the present application, such as Figure 4 As shown, the method 400 includes at least part of the following:

[0063] S410: A network controls a forwarding node to receive a first power control parameter.

[0064] S420: The network controls the forwarding node to determine a target forwarding power for signal forwarding according to the first power control parameter.

[0065] In some embodiments, the network control forwarding node may be an NCR, or may be other devices that can be controlled by a network side device to perform forwarding functions. The following description takes the network control forwarding node as an NCR as an example, but the present application is not limited to this.

[0066] In some embodiments, the first power control parameter is sent by the network side device to the NCR, and the first power control parameter is used to dynamically control the forwarding power of the signal between the network side device and the terminal device.

[0067] In some embodiments of the present application, S410 includes:

[0068] The NCR receives dynamic signaling sent by a network side device, where the dynamic signaling includes a first power control parameter, that is, the first power control parameter can be considered as a dynamic power control parameter.

[0069] Optionally, the dynamic signaling may include but is not limited to a Media Access Control Control Element (MAC CE) or a PDCCH.

[0070] That is, the network side device can realize dynamic control of the forwarding power on the NCR by dynamically indicating the power control parameter. The dynamic forwarding power control is also called on-demand forwarding power control or aperiodic power control.

[0071] It should be understood that in the embodiment of the present application, the forwarding power control method can be applied to uplink forwarding power control or downlink forwarding power control on the NCR. The uplink forwarding power refers to the forwarding power of the uplink signal from the terminal to the network side device by the NCR, and the downlink forwarding power refers to the forwarding power of the downlink signal from the network side device to the terminal by the NCR.

[0072] In some embodiments of the present application, when the NCR forwards the uplink and downlink signals between the network side device and the terminal, the transmission power of the forwarded signal can be adjusted by adjusting the amplification factor of the forwarded signal. Therefore, the control of the forwarding power can refer to the control of the amplification factor. Therefore, in the embodiments of the present application, the forwarding power can also be replaced by the amplification factor.

[0073] In the embodiment of the present application, power control is also called power adjustment, and power control parameters are also called power adjustment parameters.

[0074] In some embodiments of the present application, NCR can provide forwarding services for uplink and downlink signals between a network-side device and multiple terminals. Due to differences in the propagation environment (such as path loss) between the terminals and the network-side device, if a unified forwarding power control method is adopted, the strength of the forwarded signal reaching the receiving side may be different. If the strength is too low, it may affect the forwarding performance. If the strength is too high, it may cause interference to other devices.

[0075] In view of this, in an embodiment of the present application, the network side device may configure at least one power control loop for the NCR. Optionally, different power control loops correspond to different propagation environments, for example, corresponding to different path loss levels between the network side device and the terminal. Optionally, different power control loops correspond to different terminals or terminal groups, that is, different power control loops can be used for forwarding power control between the network side device and different terminals or terminal groups, for example, Figure 3 As shown, NCR can provide forwarding services for UE1, UE2 and UE3, then three power control loops can be configured between the network side device and NCR, which are used for forwarding power control between the network side device and UE1, UE2 and UE3 respectively. Optionally, the propagation environment between the terminal or terminal group corresponding to a power control loop and the network side device is the same or similar, for example, the path loss level is comparable. In this way, the network side device can perform differentiated forwarding power control based on the power control loop as the granularity, for example, configure the power control parameters based on the power control loop as the granularity, so that after the signals sent by the terminals or terminal groups corresponding to different power control loops are forwarded by the NCR to the network side device, the strength of the received signal of the network side device reaches the target level, or the wireless signals sent by the network side device to the terminals or terminal groups corresponding to different power control loops are forwarded by the NCR to different terminals or terminal groups, and the received signal strength reaches the target level, thereby increasing the forwarding quality of the NCR and reducing the interference caused by the NCR forwarding.

[0076] In some embodiments, the network side device can configure the power control parameters with the power control loop as the granularity. One power control loop corresponds to one terminal or terminal group, and the power control parameters corresponding to one power control loop can also be considered as the power control parameters corresponding to the terminal or terminal group, that is, the power control parameters can also be configured with the terminal or terminal group as the granularity. In other words, in the embodiment of the present application, the power control parameters of the power control loop granularity can be replaced by the power control parameters of the terminal or terminal group granularity.

[0077] In some embodiments of the present application, the first power control parameter is not limited to at least one of the following:

[0078] A power adjustment amount indication, used to indicate a power adjustment amount of forwarding power;

[0079] A power control loop identifier, used to indicate a target power control loop to which the power adjustment indication applies, that is, the power adjustment indication may be a power adjustment indication for the target power control loop;

[0080] The radio resource indication is used to indicate the target resource to which the power adjustment amount indication is applicable, that is, the power adjustment amount can be used to perform forwarding power control on the target resource.

[0081] In some embodiments, the power adjustment amount indication may also be replaced by a power indication for indicating the target forwarding power. That is, when the network side device performs forwarding power control, it may directly indicate the target forwarding power, or it may also indicate a parameter for determining the target forwarding power, such as the power adjustment amount.

[0082] In some embodiments, the power control loop identifier may also be replaced by other identifiers to indicate the applicable object of the power adjustment indication. For example, it may be replaced by a terminal identifier or a terminal group identifier, etc., to indicate the terminal or terminal group to which the power adjustment indication is applicable. That is, the power adjustment indication can only be used when forwarding a signal between a network-side device and a terminal corresponding to the terminal identifier or a terminal group corresponding to the terminal group identifier.

[0083] In some embodiments, when only one power control loop is configured between the network-side device and the NCR, the first power control parameter may not include a power control loop identifier, and the first power control parameter is applicable to the power control loop by default.

[0084] In some embodiments, the wireless resource indication includes but is not limited to at least one of the following:

[0085] A time domain resource indication, used to indicate a time domain resource to which the power adjustment amount indication (or the power adjustment amount) is applicable;

[0086] A frequency domain resource indication, used to indicate the frequency domain resource to which the power adjustment amount indication (or the power adjustment amount) is applicable;

[0087] The spatial resource indication is used to indicate the spatial resource to which the power adjustment amount indication (or the power adjustment amount) is applicable.

[0088] In some embodiments, the time domain resource indication is used to indicate at least one of the starting position, duration, and end position of the time domain resource to which the power adjustment amount indication applies. Optionally, the duration can be expressed in terms of the number of time domain units, for example, the time domain unit can be a symbol, a time slot, a subframe, etc., which is not limited in this application.

[0089] In some embodiments, the frequency domain resource indication is used to indicate the starting frequency domain position and the number of frequency domain units to which the power adjustment amount indication is applicable, or the starting frequency domain position and the ending frequency domain position. Optionally, the frequency domain unit can be a subcarrier, a carrier, a resource block (RB), a resource element (RE), a bandwidth part (BWP), etc., which is not limited in this application.

[0090] In some embodiments, the spatial resource indication includes a forwarding beam indication, such as a beam ID for indicating a forwarding beam.

[0091] In some embodiments of the present application, the power adjustment amount is a power adjustment amount relative to a first forwarding power, where the first forwarding power is the forwarding power used after the power control parameter was last received. In this case, the power adjustment amount indication is also called a relative power adjustment amount indication.

[0092] That is to say, the power adjustment amount is a relative power adjustment amount based on the previously accumulated power adjustment amount indications received. Therefore, the NCR can determine the sum of the accumulated power adjustment amount corresponding to the previously received power adjustment amount indications and the power adjustment amount corresponding to the power adjustment amount indication received this time as the total adjustment amount of the current forwarding power.

[0093] For example, for a power control loop, the power adjustment indicated by the relative power adjustment indication received for the i-th (i>=1) time is recorded as Cmd(i), and the cumulative power adjustment determined based on the power adjustment indication received for the previous i-1 times is Then the total adjustment amount of the forwarding power after receiving the i-th relative power adjustment amount indication is

[0094] Further, the NCR may determine the target forwarding power according to the reference forwarding power and the total adjustment amount. For example, the sum of the reference forwarding power and the total adjustment amount is used as the target forwarding power. Optionally, the reference forwarding power may be pre-configured by the network side device, or may be specified by the protocol, which is not limited in this application, and the specific configuration method is described in subsequent embodiments.

[0095] Optionally, for each power control loop, the network side device may also configure at least one of a maximum forwarding power and a minimum forwarding power, and may also combine at least one of the maximum forwarding power and the minimum forwarding power when determining the target forwarding power. For example, if the sum of the reference forwarding power and the accumulated power adjustment amount is within the range of the maximum forwarding power and the minimum forwarding power, the sum of the reference forwarding power and the accumulated power adjustment amount is used as the target forwarding power, or, if the sum of the reference forwarding power and the accumulated power adjustment amount is greater than the maximum forwarding power, the maximum forwarding power is used as the target forwarding power, or, if the sum of the reference forwarding power and the accumulated power adjustment amount is less than the minimum forwarding power, the minimum forwarding power is used as the target forwarding power.

[0096] It should be understood that the maximum forwarding power and the minimum forwarding power may be pre-configured by the network side device, or may be specified by the protocol. This application does not limit this, and the specific configuration method is described in subsequent embodiments.

[0097] In summary, for a power control loop, after receiving the i-th (i>=1) relative power adjustment indication, the NCR can calculate the target transmit power according to the following formula:

[0098] A(0)=Aref,i=0

[0099] A(i)′=A(i-1)+Cmd(i),i≥1

[0100]

[0101] Wherein, Aref represents the reference forwarding power (e.g., in dB), Cmd(i) represents the power adjustment amount determined according to the i-th relative power adjustment amount indication (e.g., in dB), Amax represents the maximum forwarding power (e.g., in dB), Amin represents the minimum forwarding power (e.g., in dB), and A(i) represents the forwarding power after receiving the i-th relative power adjustment amount indication (e.g., in dB).

[0102] In other embodiments of the present application, the power adjustment amount is a power adjustment amount relative to a reference forwarding power. In this case, the power adjustment amount indication is also called an absolute adjustment amount indication. In this case, the NCR can determine the target forwarding power based on the reference forwarding power and the power adjustment amount. For example, the sum of the reference forwarding power and the power adjustment amount is used as the target forwarding power. Optionally, when determining the target forwarding power, at least one of the maximum forwarding power and the minimum forwarding power can also be combined. For example, if the sum of the reference forwarding power and the power adjustment amount is within the range of the maximum forwarding power and the minimum forwarding power, the sum of the reference forwarding power and the power adjustment amount is used as the target forwarding power, or, if the sum of the reference forwarding power and the power adjustment amount is greater than the maximum forwarding power, the maximum forwarding power is used as the target forwarding power, or, if the sum of the reference forwarding power and the power adjustment amount is less than the minimum forwarding power, the minimum forwarding power is used as the target forwarding power.

[0103] For example, for a forwarding power control loop, after receiving the i-th (i>=1) absolute power adjustment indication, the NCR can calculate the target transmit power according to the following formula:

[0104] A(0)=Aref,i=0

[0105] A(i)′=Aref+Offset(i),i≥1

[0106]

[0107] Wherein, Aref represents the reference forwarding power (e.g., in dB), Offset(i) represents the power adjustment amount determined according to the i-th absolute power adjustment amount indication (e.g., in dB), Amax represents the maximum forwarding power (e.g., in dB), Amin represents the minimum forwarding power (e.g., in dB), and A(i) represents the forwarding power after receiving the i-th absolute power adjustment amount indication (e.g., in dB).

[0108] In some embodiments of the present application, the network side device may pre-configure power control related parameters for the NCR, such as the aforementioned reference forwarding power, maximum forwarding power, minimum forwarding power, etc.

[0109] For example, the network side device may send pre-configuration information to the NCR, where the pre-configuration information includes at least one of a resource list and a power control parameter related to a power control loop.

[0110] Optionally, the pre-configuration information may be sent via static or semi-static signaling.

[0111] As an example but not limitation, the network side device may send a first message to the NCR, wherein the first message includes the pre-configuration information. Optionally, the first message includes but is not limited to at least one of an RRC message, an Operation Administration and Maintenance (OAM) message, and an F1-Application Protocol (AP) (F1-AP) message.

[0112] For example, Figure 5 As shown, the network side device can first indicate the pre-configuration information to the NCR through an RRC message, an OAM message or an F1-AP message, and then indicate the dynamic power control parameters to the NCR through a MAC CE or a PDCCH, including a power adjustment amount indication and a resource indication. Further, the NCR can determine the target forwarding power based on the power adjustment amount indication, and then use the target forwarding power to forward the signal on the resources indicated by the resource indication.

[0113] In some embodiments, the resource list may include multiple resource information and resource indications (e.g., resource identifiers) corresponding to the multiple resource information. Optionally, each resource information may include at least one of a time parameter, a frequency parameter, and a spatial parameter. For example, the time parameter may include one or more of a starting position, a duration, an end position, etc., for determining a time window of a time domain resource. For example, the frequency parameter may include one or more of a starting position, a number of frequency domain units, an end position, etc., for determining a location of a frequency domain resource. For example, the spatial parameter may include a beam parameter.

[0114] In some embodiments, the resource indication in the first power control parameter is a resource identifier, and the resource identifier belongs to a resource list. The NCR can obtain corresponding resource information from the resource list according to the resource identifier, such as time parameters, frequency parameters, space parameters, etc.

[0115] In some embodiments, the power control parameters related to the power control loop include at least one of the following:

[0116] Power control ring identifier, reference forwarding power, maximum forwarding power, minimum forwarding power, forwarding power adjustment step, power adjustment amount list, and timer duration configuration.

[0117] Optionally, the power control parameters related to the power control loop may also be power control parameters related to the terminal or terminal group, that is, the network side device may indicate the preconfigured power control parameters with the terminal or terminal group as the granularity. Accordingly, the power control loop identifier may also be replaced by a terminal identifier or a terminal group identifier.

[0118] In some embodiments, the reference forwarding power may be replaced by a reference amplification factor, the maximum forwarding power may be replaced by a maximum amplification factor, and the minimum forwarding power may be replaced by a minimum amplification factor.

[0119] Optionally, for different power control loops, the reference forwarding power may be the same or different.

[0120] Optionally, for different power control loops, the maximum forwarding power may be the same or different.

[0121] Optionally, for different power control loops, the minimum forwarding power may be the same or different.

[0122] In some embodiments, the power adjustment amount list may include one or more candidate power adjustment amounts.

[0123] In some embodiments, the timer is used to control the effective duration of the power adjustment amount. For example, the duration configuration of the timer can be used to configure the initial value of the timer.

[0124] For example, after receiving a power adjustment amount indication for a power control loop, the timer starts. If no new power adjustment amount indication for the power control loop is received before the timer expires, all previously received power adjustment amount indications for the power control loop become invalid. Alternatively, if a new power adjustment amount indication for the power control loop is received before the timer expires, the timer is reset, for example, the timer is reset to an initial value.

[0125] In some embodiments, when at least one power control loop is configured between the network side device and the NCR, the pre-configuration information may include power control parameters related to each power control loop in the at least one power control loop. Optionally, the power control parameters related to different power control loops may be completely different, or partially different.

[0126] Optionally, when only one power control loop is configured between the network side device and the NCR, the power control parameters related to the power control loop do not include a power control loop identifier corresponding to the power control loop, and the power control parameters are applicable to the power control loop by default.

[0127] It should be understood that in the embodiment of the present application, some or all of the parameters in the above-mentioned pre-configuration information may also be specified by the protocol, so that the network side device does not need to pre-configure these parameters.

[0128] For example, the reference forwarding power may be preconfigured, or may be specified by a protocol.

[0129] For another example, the maximum forwarding power and the minimum forwarding power may be pre-configured, or may be specified by a protocol.

[0130] For another example, the initial value of the timer may be preconfigured, or may be specified by a protocol.

[0131] In some scenarios, there may be a situation where the resources to which the two power adjustment amount indications apply overlap. In this case, how to determine the target forwarding power on the overlapping resources is also a problem.

[0132] For example, the NCR receives a first power control parameter, in which the power adjustment amount indication is used to indicate the first power adjustment amount, and the resource indication is used to indicate the first resource. After the NCR receives the first power control parameter, the NCR receives a second power control parameter, in which the power adjustment amount indication is used to indicate the second power adjustment amount, and the resource indication is used to indicate the second resource.

[0133] Then, when the first resource and the second resource overlap (for example, partially overlap), the NCR determines the target forwarding power used on the overlapping resources according to at least one of the first power adjustment amount and the second power adjustment amount.

[0134] The following specifically describes the method for determining the target forwarding power in combination with the two indication methods of the power adjustment amount indication.

[0135] Determination method 1: corresponding to the relative power adjustment indication method

[0136] In this case, it can be considered that starting from the overlapping resources, the first power adjustment amount continues to be effective and the second power adjustment amount begins to take effect, and the previously accumulated power adjustment amount (including the first power adjustment amount) and the second power adjustment amount need to be considered when calculating the power adjustment amount. That is, the total power adjustment amount is equal to the sum of the power adjustment amount accumulated before the first power adjustment amount, the first power adjustment amount, and the second power adjustment amount.

[0137] As an implementation manner, the NCR may determine the target forwarding power used on the overlapping resources according to the reference forwarding power and the total power adjustment amount. For example, the sum of the reference forwarding power and the total power adjustment amount is determined as the target forwarding power.

[0138] As another implementation, the NCR may also determine the target forwarding power according to the first forwarding power, the first power adjustment amount, and the second power adjustment amount, wherein the first forwarding power is the forwarding power used before receiving the first power control parameter. For example, the sum of the first forwarding power, the first power adjustment amount, and the second power adjustment amount is used as the target forwarding power.

[0139] Optionally, when determining the target forwarding power, at least one of the aforementioned maximum forwarding power and minimum forwarding power may also be combined. For a specific determination method, refer to the relevant description of the aforementioned embodiment, which will not be repeated here for brevity.

[0140] After determining the target forwarding power, the NCR may start from the overlapping resources and use the target forwarding power to forward the signal until the second resource ends.

[0141] By adopting this determination method 1, when the network side device finds that the power adjustment amount indication sent previously does not adjust the forwarding power of the NCR to the target level, it can send a new power adjustment amount indication in time to supplement the forwarding power of the NCR.

[0142] Determination method 2: corresponding to the absolute power adjustment indication method

[0143] In this case, on the overlapping resources, the NCR may determine that the second power adjustment amount is the latest power adjustment amount, and further determine the target forwarding power according to the latest power adjustment amount and the reference forwarding power. For example, the sum of the reference forwarding power and the second power adjustment amount is used as the target forwarding power. Optionally, when determining the target forwarding power, at least one of the maximum forwarding power and the minimum forwarding power may also be combined. For the specific determination method, refer to the relevant description of the aforementioned embodiment, and for the sake of brevity, it will not be repeated here.

[0144] After determining the target forwarding power, the NCR may start from the overlapping resources and use the target forwarding power to forward the signal until the second resource ends.

[0145] By adopting this determination method 2, when the network side device finds that the power adjustment amount indication sent previously does not adjust the forwarding power of the NCR to the target level, it can send a new power adjustment amount indication in time to correct the forwarding power of the NCR to the target level.

[0146] In some embodiments of the present application, a network-side device may use a power control loop to perform power control on a forwarding signal between the network-side device and a terminal or terminal group. However, when a terminal or terminal group no longer needs the forwarding service provided by the NCR, the network-side device may recycle the power control loop, for example, using the power control loop to perform power control on a forwarding signal between the network-side device and other terminals or terminal groups. In this case, when the power adjustment amount indication adopts a relative power adjustment amount indication, it is necessary to reset the power control loop, for example, to reset the power adjustment amount accumulated on the power control loop. After resetting the power control loop, the accumulated power adjustment amount for the power control loop received before resetting the power control loop is no longer considered, that is, only the accumulated power adjustment amount of the power adjustment amount indication received after resetting the power control loop needs to be considered.

[0147] It should be understood that in the embodiments of the present application, the network side device can reset the power control loop in an explicit or implicit manner. The specific resetting method of the power control loop is described below in conjunction with a specific embodiment.

[0148] Reset method 1: Reset the power control loop according to the preset duration.

[0149] In some embodiments of the present application, the method 400 further includes:

[0150] The first power control loop is reset according to the effective duration of the power adjustment amount, for example, the power adjustment amount corresponding to the first power control loop is reset.

[0151] For example, if the effective duration of the power adjustment amount corresponding to the first power control loop is the first duration, then when receiving the power adjustment amount indication for the first power control loop, the NCR starts a timer, and the duration of the timer is the first duration. Before the timer times out, if a new power adjustment amount indication for the first power control loop is received, the timer is reset, and the reset duration is the first duration. If no new power adjustment amount indication for the first power control loop is received before the timer times out, the first power control loop is reset, that is, it is determined that all the power adjustment amount indications previously received for the first power control loop are invalid, and the cumulative power adjustment amount corresponding to the first power control loop is reset, for example, the cumulative power adjustment amount corresponding to the first power control loop is cleared to zero, wherein the cumulative power adjustment amount corresponding to the first power control loop is determined based on the power adjustment amount indication previously received for the first power control loop.

[0152] Optionally, the effective duration of the power adjustment amount corresponding to the first power control loop may be preconfigured, for example, determined according to the duration configuration of the timer in the preconfiguration information, or may also be specified by a protocol.

[0153] Reset method 2: Reset the power control loop through explicit instructions.

[0154] For example, the NCR may receive a reset indication from a network-side device, where the reset indication is used to indicate resetting one or more power control loops, that is, resetting power adjustment amounts corresponding to the first or multiple power control loops.

[0155] Optionally, the reset indication is used to indicate one or more power control loop identifiers. The power control loops identified by the one or more power control loop identifiers are the power control loops that need to be reset.

[0156] Optionally, the reset indication may indicate the power control loop that needs to be reset by means of a bitmap. For example, the reset indication is used to indicate a first bitmap, the first bitmap includes at least one bit, each bit corresponds to a power control loop, and the value of each bit is used to indicate whether to reset the corresponding power control loop. For example, a value of 1 indicates no reset, a value of 0 indicates reset, or vice versa.

[0157] In some embodiments of the present application, the method 400 further includes:

[0158] When the resources to which the first power control parameter applies overlap with the resources to which the third power control parameter applies, a target forwarding power for signal forwarding is determined on the overlapping resources based on the first power control parameter, wherein the third power control parameter is a semi-static or periodic power control parameter.

[0159] For example, when the resources to which the dynamic power adjustment indication applies overlap with the resources to which the semi-static or periodic power control parameters apply, the target forwarding power is determined on the overlapping resources according to the dynamic power adjustment indication. Among them, the forwarding power control method based on the semi-static or periodic power control parameters uses the same power adjustment indication to determine the forwarding power on the periodic resources, that is, the forwarding power on the periodic resources is the same. Therefore, determining the target forwarding power based on the dynamic power adjustment indication is conducive to realizing timely power adjustment on demand, ensuring that the forwarding power of the NCR is adjusted to the target level, and improving the forwarding performance.

[0160] In summary, in an embodiment of the present application, the network side device can dynamically indicate a power control parameter to the network control forwarding node. The power control parameter is associated with a power control loop. The power control loop can be designed based on the propagation environment between the terminal and the network side device. For example, different power control loops correspond to different propagation environments, so that the network device can implement differentiated forwarding power control of the network control forwarding node based on the difference in the propagation environment, which is conducive to enhancing the forwarding quality of the network control forwarding node and reducing the interference caused by the forwarding of the network control forwarding node.
