[0031] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application.

In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0033] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), Reconfigurable Intelligent Surface (RIS) and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the technology described can be used for the systems and radio technologies mentioned above, as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for illustrative purposes, and NR terminology is used in most of the following description, but these technologies can also be applied to applications other than NR system applications, such as 6th generation (6G) systems. th Generation, 6G) communication system.

[0034] Figure 1The following is a schematic diagram illustrating the structure of a wireless communication system applicable to embodiments of the present application. The wireless communication system includes a terminal 11 and a network-side device 12. Terminal 11 may also be referred to as a terminal device or user equipment (UE). Terminal 11 may be a mobile phone, tablet personal computer, laptop computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), wearable device, vehicle-mounted equipment (VUE), pedestrian terminal (PUE), or other terminal-side devices. Wearable devices include smart watches, bracelets, headphones, glasses, etc. It should be noted that the specific type of terminal 11 is not limited in the embodiments of the present application. The network side device 12 can be a base station or a core network, where the base station can be called a node B, an evolved node B, an access point, a base transceiver station (Base Transceiver Station, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting and receiving point (Transmitting Receiving 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 a specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0035] The amplifier can be understood as a smart amplifier, signal amplifier, etc. In this embodiment, the amplifier may include a mobile termination module (MT) and a radio unit (RU). The MT is used to establish a connection with network-side devices (such as gNBs, donor nodes, core network nodes, etc.). That is, the network-side devices exchange information with the amplifier through the MT, allowing the amplifier to accept control from the network-side devices. For example, the network-side devices can control the amplifier's transmission parameters, amplifier on / off, and transmit beams. The RU is used to establish a connection with the UE for signal exchange.

[0036] It should be noted that the amplifier can be understood as a network node, located between the UE and the network side device, to achieve amplification, forwarding and other processing of uplink / downlink signals.

[0037] The technical solutions provided by the embodiments of the present application are described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0038] like Figure 2 FIG. 2 is a flow chart of a method 200 for controlling an amplifier according to an exemplary embodiment of the present application. The method 200 may be, but is not limited to, executed by the amplifier, specifically by hardware and / or software installed in the amplifier. In this embodiment, the method 200 may include at least the following steps.

[0039] S210: The amplifier determines a target state according to the terminal access state and / or first information indicated by the network side device.

[0040] The terminal access status refers to whether a terminal is connected to the amplifier, that is, whether a terminal and / or network-side devices need to amplify or forward signals within the amplifier's coverage. In this embodiment, the terminal access status can be determined autonomously by the amplifier or indicated by the network-side device.

[0041] The first information is used to indicate the state of the amplifier, such as whether a state switching is required, or the target state to which the amplifier needs to be switched.

[0042] Of course, the target state may include a first state or a second state. The first state refers to the amplifier (e.g., the RU) amplifying and / or forwarding input signals (e.g., signals sent by a terminal or network-side device). The first state can be understood as an ON state, which may include a power-on state, a state where the RU is normally amplifying or forwarding input signals, and the like.

[0043] The second state means that the amplifier does not amplify and / or forward input signals (such as signals sent by a terminal or network-side device). The second state can be understood as an OFF state, which can include at least one of a RU sleep state, a low output power state, and a power-off state.

[0044] It should be noted that, depending on different communication designs, the low amplification state of the amplifier may belong to the second state or the first state, and there is no limitation here.

[0045] S220: The amplifier switches states according to the target state. It can be understood that when the amplifier switches states according to the target state, if the target state is the same as the current state, the amplifier does not switch; if the target state is different from the current state of the amplifier, the amplifier can switch from the current state to the target state.

[0046] In this embodiment, the amplifier determines a target state through terminal state information and first information indicated by a network-side device, and then switches states according to the target state. As a result, the amplifier can switch between the first state and the second state when signal forwarding or amplification is not required, thereby achieving the purpose of saving power and reducing interference caused by noise amplification in the wireless communication system, thereby ensuring the quality of wireless communication.

[0047] For example, assuming that there is no signal that needs to be amplified on the amplifier within a certain period of time, the amplifier can be switched to the second state (i.e., the OFF state) to avoid amplifying interference signals and noise on other cells, thereby ensuring the signal reception quality of the current cell; or, the amplifier can avoid sending side lobes and noise signals of the current cell's signal to other cells, thereby ensuring the signal reception quality of other cells.

[0048] like Figure 3 FIG. 1 is a flow chart of a method 300 for controlling an amplifier according to an exemplary embodiment of the present application. The method 300 may be, but is not limited to, executed by the amplifier, specifically by hardware and / or software installed in the amplifier. In this embodiment, the method 300 may include at least the following steps.

[0049] S310: The amplifier determines a target state according to first information indicated by a network-side device.

[0050] It can be understood that, in addition to referring to the relevant description in method embodiment 200, the implementation process of S310 may include, as a possible implementation method, at least one of the following (101)-(113).

[0051] (101) First indication information, used to instruct the amplifier to switch states or not to switch states.

[0052] The first indication information may be downlink control information (DCI), medium access control-control element (MAC CE), slot format indication (SFI), (Radio Resource Control, RRC) signaling, etc.

[0053] Taking DCI as an example, the network side device can explicitly or implicitly instruct the amplifier to switch or not switch through DCI. For example, one code point in the DCI can instruct the amplifier to switch state, while another code point can instruct the amplifier not to switch state.

[0054] For another example, a code point in the DCI may be used to instruct the amplifier to switch its state, such as switching the amplifier from the ON state to the OFF state; or from the OFF state to the ON state.

[0055] (102) Second indication information, used to indicate whether the amplifier is in the first state or the second state.

[0056] Among them, similar to the first indication information, the second indication information can also be DCI, MAC CE, SFI, RRC signaling, etc.

[0057] Continuing to take DCI as an example, the network-side device may indicate that the amplifier is in the first state or the second state in an explicit or implicit manner.

[0058] For example, one code point in the DCI may indicate that the amplifier is in the first state, and another code point may indicate that the amplifier is in the second state.

[0059] For another example, one code point in the DCI may indicate that the amplifier is in the first state 1 (for DRX configuration 1), another code point indicates that the amplifier is in the first state 2 (for DRX configuration 2), and another code point indicates that the amplifier is in the second state.

[0060] For another example, one code point indicates that the amplifier is in the first state 1 (corresponding to amplification factor alpha 1), another code point indicates that the amplifier is in the first state 2 (corresponding to amplification factor alpha 2), and another code point indicates that the amplifier is in the second state.

[0061] In addition, when the second indication information is used to indicate that the amplifier is in the first state or the second state, the indication method may include at least one of the following (1021)-(1024).

[0062] (1021) Indicates that the resources of the amplifier in the downlink (DL) time unit are in the ON state (ie, the first state).

[0063] (1022) Indicates that the amplifier's resources in an uplink (UL) time unit are in an ON state.

[0064] (1023) Indicating the resources of the amplifier in a flexible time unit, which is in an ON state if at least some of the following conditions (a) to (d) are met.

[0065] (a) There is a semi-static UL / DL configuration in the flexible time unit.

[0066] (b) Flexible: Dynamic UL / DL scheduling exists on the time unit.

[0067] (c) The flexible time unit contains dynamic indication information of the base station.

[0068] (d) The flexible time unit includes scheduling of the Physical Random Access Channel (PRACH) and the Physical Uplink Control Channel (PUCCH).

[0069] (e) The flexible time unit includes at least one of the following: a channel state information reference signal (CSI-RS), a synchronization signal block (SSB), and a common search space (CSS).

[0070] (1024) Indicates that the amplifier is in OFF state when resources (which may be time domain resources and / or frequency domain resources) are not available (NA).

[0071] Optionally, the time unit mentioned in this embodiment and subsequent embodiments may be a sub-slot, a time slot, a sub-frame, a frame, a symbol, a second (s), a millisecond (ms), etc., and is not limited here.

[0072] (103) Data scheduling information.

[0073] The data scheduling information may be used to schedule UL data, DL data, and the like.

[0074] Based on this, in the case where the first information includes data scheduling information, the amplifier determines the target state according to the data scheduling information indicated by the network side device, which may include at least one of the following (1031)-(1033).

[0075] (1031) In a case where the scheduled data indicated by the data scheduling information is UL data and / or DL data, determining that the target state is the first state (ie, ON state).

[0076] For example, at time unit n, if the scheduled data indicated by the data scheduling information is UL data and / or DL data, then the state of the amplifier at time unit n is the first state, ie, the ON state.

[0077] (1032) When the data scheduling information does not schedule UL data and DL data, determine that the target state is the second state.

[0078] For example, at time unit n, if the data scheduling information does not schedule UL data and DL data, then the state of the amplifier at time unit n is the second state, that is, the OFF state.

[0079] (1033) When the scheduling data indicated by the data scheduling information is predetermined data, determining that the target state is the first state, wherein the predetermined data includes at least one of PRACH, PUCCH, Sounding Reference Signal (SRS), CSI-RS, SSB, and CSS (such as type 1 CSS).

[0080] (104) Time Division Duplexing (TDD) configuration information.

[0081] Wherein, in the case where the first information includes TDD configuration information, the amplifier determines the target state according to the TDD configuration information indicated by the network side device, which may include at least one of the following (1041)-(1043).

[0082] (1041) In a case where the TDD configuration includes a UL configuration and / or a DL configuration, determining that the target state is the first state.

[0083] For example, at time unit n, if the TDD configuration includes UL configuration and / or DL configuration, then the state of the amplifier at time unit n may be the first state, ie, the ON state.

[0084] (1042) When the TDD configuration includes a flexible configuration, determine that the target state is the second state.

[0085] For example, at time unit n, if the TDD configuration includes a flexible configuration, then the state of the amplifier at time unit n is the second state, that is, the OFF state.

[0086] (1043) Determine the target state according to the configuration ratio of the TDD, wherein the configuration ratio is a ratio between a first configuration and a second configuration, the first configuration includes a UL configuration and / or a DL configuration, and the second configuration includes a flexible configuration.

[0087] For example, when the ratio is greater than a second threshold, the target state is determined to be the first state; when the ratio is not greater than the second threshold, the target state is determined to be the second state, wherein the second threshold can be implemented by protocol agreement, high-level configuration, or network configuration.

[0088] (105) Beam information.

[0089] The beam information may include beam direction, beam quantity, etc.

[0090] (106) Beam ID or beam index.

[0091] For example, for (105) and (106), when the load information is included in the first information, the target state is set to the first state by default, and vice versa. (107) The transmission power of the amplifier.

[0092] For example, when the transmission power of the amplifier is greater than the second threshold, the target state is determined to be the first state; when the transmission power of the amplifier is not greater than the third threshold, the target state is determined to be the second state, wherein the third threshold can be implemented by protocol agreement, high-level configuration, or network configuration.

[0093] (108) Discontinuous Reception (DRX) configuration information. For example, when the DRX configuration information is DRX configuration 1 or DRX configuration 2, the target state is determined to be the first state.

[0094] (109) Terminal identification information.

[0095] For example, when the terminal corresponding to the terminal identification information is a terminal under the coverage of the amplifier, the target state is determined to be the first state; otherwise, the target state is determined to be the second state.

[0096] For another example, when the first information includes the terminal identification information, the target state is assumed to be the first state by default; otherwise, the target state is assumed to be the second state by default.

[0097] (110) Traffic load information.

[0098] For example, when the load information is greater than a third threshold, the target state is determined to be the first state; otherwise, the target state is determined to be the second state.

[0099] For another example, when the first information includes the load information, the target state is assumed to be the first state by default; otherwise, the target state is assumed to be the second state by default.

[0100] (111) Target resource information, wherein the target resource information includes at least one of hard resource information, soft resource information, and unavailable resource information.

[0101] Wherein, in the case where the first information is the target resource information, the amplifier determines the target state according to the target resource information indicated by the network side device, including at least one of the following (1111)-(1113).

[0102] (1111) When the target resource information is the hard resource, determine that the target state is the first state.

[0103] (1112) When the target resource information is the unavailable resource, determine that the target state is the second state.

[0104] (1113) When the target resource information is the soft resource, determine that the target state is the second state or the first state.

[0105] If the target resource information is the soft resource, it indicates DRX configuration 1, or the identification magnification is alpha1, or it is a pending first state or a pending second state.

[0106] Based on this, as a possible implementation method, when the target resource information is the soft resource and the third indication information sent by the network side device is received, the target state is determined according to the third indication information, and the third indication information is used to indicate that the amplifier is in the first state or the second state; and / or, when the target resource information is the soft resource, the target state is defaulted to the second state.

[0107] Exemplarily, if the soft resource information indicates a pending first state and a second state, then a network-side device such as a base station can dynamically indicate in the soft resource through third indication information whether the amplifier is in the first state or the second state. If there is no base station dynamically indicating that the amplifier in the soft resource is in the first state, the amplifier is defaulted to the second state.

[0108] (112) Master Cell Group (MCG) configuration information.

[0109] (113) Secondary Cell Group (SCG) configuration information.

[0110] In which, when the first information includes MCG configuration information and / or SCG configuration information (that is, the amplifier is in a dual-connection state), the amplifier determines the target state according to the MCG configuration information and / or the SCG configuration information indicated by the network side device, including at least one of the following (1131)-(1132).

[0111] (1131) When both the MCG configuration information and the SCG configuration information indicate that the state of the amplifier is the second state, determine that the target state is the second state.

[0112] (1132) When the MCG configuration information or the SCG configuration information indicates that the state of the amplifier is a first state, determine that the target state is the first state.

[0113] In addition, as a possible implementation method, the amplifier can also determine the target state only based on the MCG configuration information. The determination process can refer to the relevant implementation methods in the aforementioned (101)-(111), etc. To avoid repetition, no limitation is made here.

[0114] As another possible implementation, the MCG configuration information and the SCG configuration information may indicate not only the working state of the amplifier but also the working time, working frequency, etc. of the amplifier. This will be explained below in conjunction with (1133)-(1137).

[0115] (1133) When the MCG configuration information indicates that the operating time range of the amplifier is a first time range and the SCG configuration information indicates that the operating time range of the amplifier is a second time range, the operating time range of the amplifier is the sum of the first time range and the second time range.

[0116] For example, assuming that the first time range is (T1, T2) and the second time range is (T2, T3), then the operating time range of the first amplifier is (T1, T2, T3).

[0117] (1134) When the MCG configuration information indicates that the operating time range of the amplifier is a first time range and the SCG configuration information indicates that the operating time range of the amplifier is a second time range, the operating time range of the amplifier is the overlapping part between the first time range and the second time range.

[0118] For example, assuming that the first time range is (T1, T2, T3) and the second time range is (T2, T3), then the operating time range of the first amplifier is (T2).

[0119] (1135) When the configuration information of the MCG indicates that the operating frequency range of the amplifier is a first frequency range and the configuration information of the SCG indicates that the operating frequency range of the amplifier is a second frequency range, the operating frequency range of the amplifier is the sum of the first frequency range and the second frequency range.

[0120] For example, assuming that the first time range is (F1, F2) and the second time range is (F2, F3), then the operating time range of the first amplifier is (F1, F2, F3).

[0121] (1136) When the configuration information of the MCG indicates that the operating frequency range of the amplifier is a first frequency range and the configuration information of the SCG indicates that the operating frequency range of the amplifier is a second frequency range, the operating frequency range of the amplifier is an overlapping part between the first frequency range and the second frequency range.

[0122] For example, assuming that the first time range is (F1, F2, F3) and the second time range is (F2, F3), then the operating time range of the first amplifier is (F2).

[0123] (1137) When the MCG configuration information indicates that the operating time range of the amplifier is the first time range and the operating frequency range is the first frequency range; and the SCG configuration information indicates that the operating time range of the amplifier is the second time range and the operating frequency range is the second frequency range, the operating time range of the amplifier is the overlapping part between the first time range and the second time range, and the operating frequency range of the amplifier is the sum of the first frequency range and the second frequency range.

[0124] In addition to the aforementioned (1133)-(1137), when the MCG configuration information and the SCG configuration information are different, the amplifier may determine the operating frequency range of the RU portion based solely on the SCG configuration information. However, if the amplifier does not operate for a period of time after obtaining the SCG configuration information, then the amplifier may suspend amplification / transmission of the SCG frequency band.

[0125] It should be noted that, based on the aforementioned implementations, if the first information is transmitted through the fifth information, then the fifth information may also carry at least one of the start time, end time, and duration of the target state of the amplifier.

[0126] In addition, the effective time of the fifth information can be determined based on the first time unit and the first value of receiving the fifth information; or, the effective time of the fifth information is determined based on the seventh indication information sent by the network side device.

[0127] For example, assuming that the first value is L, and the amplifier receives the fifth information at time unit n, then the effective time of the first information indicated by the fifth information may be time unit n+L.

[0128] For another example, assuming that the first value is L, and the amplifier uses the first information indicated by the fifth information at time unit n, then the receiving time unit of the fifth information may be time unit nL.

[0129] Optionally, the first value is related to the subcarrier spacing (SCS), or the first value is implemented by network side indication, protocol agreement or high-level configuration, such as indication through the fifth information, etc., which is not limited here.

[0130] It will be appreciated that if the first value is related to the SCS, a predefined relationship between the first value and the SCS can be used. For example, when the SCS is 15 kHz, the first value is K1; when the SCS is 30 kHz, the first value is K2; when the SCS is 60 kHz, the first value is K3; and when the SCS is 120 kHz, the first value is K4. In this case, if the effective time of the fifth information needs to be determined, the first value can be determined based on the predefined relationship between the first value and the SCS.

[0131] It should be noted that the effective time of the subsequent second information or other indication information can refer to the aforementioned description of the effective time of the fifth information. To avoid repetition, this will not be described in detail later.

[0132] In this embodiment, the amplifier determines and switches the target state through the first information indicated by the network-side device, thereby enabling the amplifier to effectively forward and amplify signals in the first state, and also to reduce interference within the system in the second state to ensure wireless communication quality.

[0133] like Figure 4a FIG. 4 is a flow chart of a method 400 for controlling an amplifier according to an exemplary embodiment of the present application. The method 400 may be, but is not limited to, executed by the amplifier, specifically by hardware and / or software installed in the amplifier. In this embodiment, the method 400 may include at least the following steps.

[0134] S410: The amplifier determines the terminal access status according to second information indicated by the network-side device.

[0135] It should be noted that when the network-side device indicates the terminal access status to the amplifier through the second information, the second information may include at least one of the following (201)-(206).

[0136] (201) Fourth indication information, used to indicate whether a terminal is connected to the amplifier.

[0137] The fourth indication information may be DCI, RRC, MAC CE, etc.

[0138] Taking DCI as an example, the network side device may indicate the terminal access status in an explicit or implicit manner through DCI.

[0139] For example, one code point indicates that the terminal access status is that a terminal is connected to the amplifier, and another code point indicates that the terminal access status is that a terminal is not connected to the amplifier.

[0140] (202)SSB configuration information.

[0141] Among them, if the amplifier detects SSB information sent by the terminal or the network side device, the amplifier believes that there is UE access; if no SSB information is detected, it is considered that there is no terminal access.

[0142] (203) Paging configuration information.

[0143] If the amplifier detects paging information sent by the network side or the terminal at the paging position, the amplifier considers that a UE has accessed; if no paging information is detected, the amplifier considers that no terminal has accessed.

[0144] (204) Control resource set (CORESET) configuration information.

[0145] Among them, if the amplifier detects control information sent by the network side or the UE at the position of the CORESET, the amplifier considers that there is UE access; if no control information is detected, it is considered that there is no terminal access.

[0146] (205) Search space configuration information.

[0147] If the amplifier detects control information sent by the network side or the terminal at a position in the configured search space, the amplifier considers that the terminal has accessed; if no control information is detected, the amplifier considers that no terminal has accessed.

[0148] (206) Data scheduling information.

[0149] If the amplifier detects scheduling information from the network side or data transmission from the terminal, the amplifier considers that there is UE access; if not, the amplifier considers that there is no terminal access.

[0150] Alternatively, when the scheduled data indicated by the data scheduling information is UL data and / or downlink DL data, the terminal access status is determined to be that a terminal is accessed on the amplifier.

[0151] Alternatively, when the data scheduling information does not schedule UL data and DL data, it is determined that the terminal access status is that there is no terminal access on the amplifier.

[0152] In one implementation, the second information may be determined by the network side device according to any one of the second measurement result, the third measurement result, the fourth measurement result, and the fifth measurement result and then sent to the amplifier.

[0153] The second measurement result is a measurement result of the terminal measuring the first downlink measurement information sent by the network side device, and the first downlink measurement information is information sent by the network side device to the terminal when the amplifier is in the second state.

[0154] The third measurement result is a measurement result of the network-side device measuring first uplink measurement information sent by the terminal, where the first uplink measurement information is information sent by the terminal to the terminal when the amplifier is in the second state.

[0155] The fourth measurement result is a measurement result of the terminal measuring second downlink measurement information sent by the network-side device, where the second downlink measurement information is information sent by the network-side device to the terminal when the amplifier is in the first state.

[0156] The fifth measurement result is a measurement result of the network-side device measuring second uplink measurement information sent by the terminal, where the second uplink measurement information is information sent by the terminal to the terminal when the amplifier is in the first state.

[0157] In this case, in order to avoid the influence of the amplifier on the aforementioned second measurement result, third measurement result, fourth measurement result, and fifth measurement result and ensure the accuracy of the measurement results, the amplifier may further receive fifth indication information sent by the network-side device before determining the terminal access state according to the second information indicated by the network-side device, wherein the fifth indication information carries at least a switching command and / or related time information, the switching command is used to instruct the amplifier to switch to the first state or the second state, and the related time information is the time information when the amplifier switches to the first state or the second state, so that the amplifier can switch states according to the switching command and / or the related time information.

[0158] Optionally, the relevant time information is the network-side device notifying the amplifier of measurement signal setting information, causing the amplifier to be turned off or on at the corresponding time. Based on this, in this embodiment, the relevant time information may include at least one of the following: the sending time information of the first downlink measurement information, the sending time information of the first uplink measurement information, the sending time information of the second downlink measurement information, and the sending time information of the second uplink measurement information. In addition, depending on the measurement requirements, the relevant time information may also include at least one of the start time, end time, and duration of the first state or the second state.

[0159] As a possible implementation method, the relevant time information can also be obtained by Figure 4bThe on / off pattern shown in the figure is used when the amplifier is activated / turned on.

[0160] Based on this, assuming that the network-side device is a donor node, this embodiment describes the process of determining the second measurement result, the third measurement result, the fourth measurement result, and the fifth measurement result with reference to different examples, as follows.

[0161] In Example 1, the donor node indicates the time range for temporarily shutting down the amplifier through the fifth indication information. During the time range for shutting down the amplifier, the donor sends a downlink measurement signal (for example, an aperiodic CSI-RS) to at least one terminal under the coverage of the amplifier. Then, the donor node determines whether it is necessary to at least shut down the downlink amplification of the amplifier, that is, whether there is terminal access, based on the measurement result reported by the terminal (i.e., the second measurement result), and sends the judgment result to the amplifier in the form of the second information.

[0162] In Example 2, the donor node indicates the time range for temporarily shutting down the amplifier through the fifth indication information. During the time range for shutting down the amplifier, the donor instructs the UE to send an uplink measurement signal (such as periodic SRS, semi-persistent SRS, aperiodic SRS) to at least one donor under the coverage of the amplifier. The donor determines whether it is necessary to at least shut down the uplink amplification of the amplifier based on the measurement result (i.e., the third measurement result), that is, whether there is terminal access, and sends the judgment result to the amplifier in the form of the second information.

[0163] Example 3: The fifth indication information of the donor node indicates the time range for temporarily turning on the amplifier. During the time range for turning on the amplifier, the donor sends a downlink measurement signal (such as SSB, CSI-RS) to at least one terminal under the coverage of the amplifier. The donor determines whether it is necessary to at least turn on the amplifier for downlink amplification, that is, whether there is terminal access, based on the measurement result reported by the terminal (that is, the fourth measurement result), and sends the judgment result to the amplifier in the form of the second information.

[0164] Example 4: The fifth indication information of the donor node indicates the time range for temporary activation of the amplifier. During the time range for activation of the amplifier, the donor instructs the UE to send an uplink measurement signal (such as periodic SRS, semi-persistent SRS, aperiodic SRS) to at least one donor under the coverage of the amplifier. The donor determines whether it is necessary to at least activate the uplink amplification of the amplifier based on the measurement result (i.e., the fifth measurement result), that is, whether there is terminal access, and sends the judgment result to the amplifier in the form of the second information.

[0165] S420: The amplifier determines a target state according to the terminal access state.

[0166] It is understood that the implementation process of S420 can refer to the relevant descriptions in the method embodiments 200 and 300. As a possible implementation method, refer to Figure 4a The implementation process of S420 may further include S421 and / or S422, the contents of which are as follows.

[0167] S421: When the terminal access state is that a terminal is connected to the amplifier, determine that the target state is the first state.

[0168] That is, when there are terminals and / or network-side devices under the coverage of the amplifier that need to transmit information, the amplifier is switched to or remains in the ON state.

[0169] S422: When the terminal access state is that no terminal is connected to the amplifier, determine that the target state is the second state.

[0170] That is, when there is no terminal and / or network-side equipment that needs to transmit information under the coverage of the amplifier, the amplifier is switched to or remains in the OFF state.

[0171] S430: The amplifier switches state according to the target state.

[0172] It can be understood that the implementation process of S430 can refer to the relevant descriptions in method embodiments 200-400 and achieve the same technical effect. To avoid repetition, it will not be described here.

[0173] In this embodiment, the amplifier determines the terminal access status through the second information, and then determines and switches the target state according to the terminal access status. As a result, the amplifier can effectively forward and amplify signals in the first state, and can also reduce interference within the system in the second state to ensure the quality of wireless communication.

[0174] like Figure 5FIG. 5 is a flow chart of a method 500 for controlling an amplifier according to an exemplary embodiment of the present application. The method 500 may be, but is not limited to, executed by the amplifier, specifically by hardware and / or software installed in the amplifier. In this embodiment, the method 500 may include at least the following steps.

[0175] S510: The amplifier determines the terminal access state according to a first measurement result of third information.

[0176] The third information may be uplink measurement information sent by the terminal under the coverage of the amplifier or downlink measurement information sent by the network side device. For example, in this embodiment, the third information may include at least one of SRS, PRACH, Physical Uplink Shared Channel (PUSCH), PUCCH, and Demodulation Reference Signal (DMRS).

[0177] As a possible implementation manner, the amplifier determines the terminal access state according to a first measurement result of the third information, including at least one of the following (301)-(304).

[0178] (301) When the first measurement result is that no uplink signal is measured, determine that the terminal access state is that there is no terminal access to the amplifier.

[0179] (302) When the first measurement result is less than a first threshold, determine that the terminal access status is that there is no terminal access on the amplifier.

[0180] (303) When the first measurement result is not less than a first threshold, determine that the terminal access status is that a terminal is connected to the amplifier.

[0181] (304) When the first measurement result is that an uplink signal is measured, determining that the terminal access state is that a terminal is accessed to the amplifier.

[0182] The first threshold may be determined by protocol agreement, high-layer signaling configuration, or network-side configuration, and is not limited here.

[0183] In addition, the measurement time for the amplifier to measure the third information may also be implemented by a protocol agreement, a high-layer configuration, a network indication, or a network configuration. For example, the amplifier may receive sixth indication information sent by the network-side device, where the sixth indication information carries measurement time activation information and / or measurement time indication information; the amplifier then determines a target measurement time based on the measurement time activation information and / or the measurement time indication information, and measures the third information based on the target measurement time to obtain the first measurement result.

[0184] Among them, the measurement time can be a periodic configuration or a semi-static periodic configuration, the sixth indication information can be a DCI activation indication or a wake-up signal (WUS), etc., and the detection time of the sixth indication information (which can also be understood as the detection time of the measurement time activation information or the measurement time indication information) can be implemented by protocol agreement, high-level configuration or network configuration, etc.

[0185] For example, the network side device may configure a semi-static detection cycle and determine the activation moment of the measurement time according to a DCI activation instruction. If the DCI is activated, the amplifier measures the third information in the next configured detection cycle.

[0186] For another example, the network-side device configures a semi-static detection period and a dynamic activation indication detection time. Then, the amplifier can monitor the dynamic indication signaling DCI within the dynamic activation indication detection time. If the dynamic indication signaling DCI (that is, a WUS signaling) is detected, the amplifier switches to the ON state.

[0187] In addition, as an implementation manner, when the sixth indication information carries the measurement time activation information and the amplifier is in the second state, the amplifier switches to the first state.

[0188] S520: The amplifier determines a target state according to the terminal access state.

[0189] S521: When the terminal access state is that a terminal is connected to the amplifier, determine that the target state is the first state.

[0190] S522: When the terminal access state is that no terminal is connected to the amplifier, determine that the target state is the second state.

[0191] S530: The amplifier switches its state according to the target state. It can be understood that the implementation process of S520, S521, S522, and S530 can refer to the relevant descriptions in method embodiments 200-400 and achieve the same technical effect. To avoid repetition, it will not be repeated here.

[0192] In this embodiment, the amplifier determines the terminal access state through the first measurement result, and then determines and switches the target state according to the terminal access state. As a result, the amplifier can effectively forward and amplify signals in the first state, and can also reduce interference within the system in the second state to ensure wireless communication quality.

[0193] like Figure 6a FIG. 6 is a flow chart of a method for controlling an amplifier according to an exemplary embodiment of the present application. The method 600 may be, but is not limited to, executed by the amplifier, and may specifically be executed by hardware and / or software installed in the amplifier. In this embodiment, the method 600 may include at least the following steps.

[0194] S610: When at least one state configuration information is configured in the amplifier, determine target configuration information based on the at least one state configuration information.

[0195] Among them, the state configuration information is configured with the state determination rule of the amplifier. For example, the state configuration information may be configured with whether the amplifier determines the target state based on the terminal access state, or determines the target state based on the first information indicated by the network side device, or determines the target state based on both the terminal access state and the first information indicated by the network side device, or the time when the amplifier determines the target state, parameters involved in the target state determination process such as state switching timing, etc. This embodiment does not impose any restrictions on this.

[0196] In one implementation, the at least one state configuration information may be configured according to a predetermined dimension, wherein the predetermined dimension may include at least one of the following (401)-(408).

[0197] (401)UL dimension.

[0198] (402)DL dimension.

[0199] (403) Time unit dimension.

[0200] Among them, the aforementioned (401)-(403) can be understood as: a set of state configuration information can be independently configured based on the UL dimension, and / or a set of state configuration information can be independently configured based on the DL dimension. In this embodiment, considering the asymmetry between UL and DL, a set of state configuration information can be configured based on the time unit without considering the UL / DL configuration.

[0201] (404) Time division multiplexing (TDM) dimension.

[0202] (405) Frequency division multiplex (FDM) dimension.

[0203] (406) Space Division Multiplexing (SDM) dimension.

[0204] Among them, (404)-(406) can be understood as: a set of state configuration information can be independently configured based on the TDM dimension, a set of state configuration information can be independently configured based on the FDM dimension, and a set of state configuration information can be independently configured based on the SDM dimension.

[0205] In this case, the amplifier may apply corresponding configuration according to the multiplexing mode. For example, if the multiplexing mode is TDM, then the state configuration information based on the TDM dimension configuration may be applied.

[0206] (407) A frequency domain dimension, wherein the frequency domain dimension includes at least one sub-frequency domain dimension.

[0207] That is, each frequency range (Per frequency range) is independently configured with a set of state configuration information.

[0208] (408) A time domain dimension, wherein the time domain dimension includes at least one sub-time domain dimension.

[0209] That is, each time range (Per time range) is independently configured with a set of state configuration information.

[0210] It should be noted that the state configuration information based on different dimensional configurations given in (401)-(408) above can be used in combination or individually, and there is no limitation here.

[0211] S620: The amplifier determines a target state according to the terminal access state and / or the first information indicated by the network side device.

[0212] It can be understood that in addition to referring to the relevant descriptions in method embodiments 200-500, as a possible implementation method, referring to Figure 6 again, the implementation process of S610 can also refer to S621, the content of which is as follows.

[0213] S621: Based on the target configuration information, the amplifier determines the target state according to the terminal access state and / or the first information indicated by the network side device.

[0214] Among them, the implementation process of S621 is different depending on the target configuration information. For example, assuming that the target configuration information configures the amplifier to determine the terminal access state based on the first measurement result, and to determine the target state based on the terminal access state, then when determining the target state, the amplifier needs to determine the terminal access state based on the first measurement result, and then determine the target state based on the terminal access state.

[0215] S630: The amplifier switches state according to the target state. The target state includes a first state or a second state, the first state means that the amplifier amplifies and / or forwards the input signal, and the second state means that the amplifier does not amplify and / or forward the input signal.

[0216] It can be understood that the implementation process of S630 can refer to the relevant descriptions in method embodiments 200-500. To avoid repetition, it will not be repeated here.

[0217] S640: When the amplifier is in the second state but needs to forward and / or amplify the signal sent by the target device, the amplifier switches from the second state to the first state.

[0218] The target device is a terminal and / or network-side device within the amplifier's coverage. That is, if a signal requiring forwarding or amplification occurs between a terminal and / or network-side device within the amplifier's coverage, the amplifier can be switched from the OFF state to the ON state to forward and amplify the signal.

[0219] As a possible implementation, upon receiving the fourth information sent by the network-side device, the amplifier may determine, based on the fourth information, whether to forward and / or amplify the signal sent by the target device. The process for determining the fourth information may refer to the aforementioned description of the process for determining the second information and will not be repeated here to avoid repetition.

[0220] S650: When the amplifier is switched to the first state, the amplifier amplifies the signal based on the first working mode.

[0221] The amplifier is configured with at least one working mode (pattern), each working mode is configured with at least one amplification factor of the amplifier, different amplification factors correspond to different time domain information and / or frequency domain information, and the first working mode belongs to the at least one working mode.

[0222] For example, please refer to Figure 6bAssuming that "on" indicates that the amplifier operates in a preset operating mode and "off" indicates that the amplifier is turned off, multiple operating modes can be set, and when a first condition is met, the amplifier can switch modes. For example, the amplifier switches from the first operating mode (such as Figure 6c pattern#1) is switched to the second working mode (as shown in Figure 6c pattern#2 shown), the second working mode is another working mode in the at least one working mode except the first working mode.

[0223] Optionally, the first condition may be determined according to at least one of the following (501)-(511).

[0224] (501) The mode switching instruction sent by the network side device.

[0225] For example: if the amplifier is in the ON state and the network device indicates a mode switch, the amplifier switches from the ON state to the OFF state; if the amplifier is in the OFF state and the network device indicates a mode switch, the amplifier switches from the OFF state to the ON state; If the amplifier is in the ON state and the network device indicates that it is not switching, the amplifier remains in the ON state; if the amplifier is in the OFF state and the network device indicates that it is not switching, the amplifier remains in the OFF state; (502) The working time of the first working mode.

[0226] For example, if the amplifier is in the ON state for a time length greater than a first preset value, the amplifier is switched to the ON state; or if the amplifier is in the OFF state for a time length greater than a second preset value, the amplifier is switched to the OFF state.

[0227] (503) Data scheduling information.

[0228] For example: if the terminal or amplifier is configured or instructed to perform uplink transmission or downlink transmission at the target time unit, the amplifier is in the ON state at the target time unit; if the terminal or amplifier is configured or instructed that there is no scheduled transmission at the target time unit, the amplifier is in the OFF state at the target time unit.

[0229] (504) TDD configuration information.

[0230] For example, if the TDD configuration information indicates that the target time unit is a UL time unit or a DL time unit, the amplifier is in the ON state; if the TDD configuration information indicates that the target time unit is a flexible time unit, the amplifier is in the OFF state.

[0231] (505) Beam information.

[0232] For example, if the amplifier is in the ON state and the network side indicates that the beam direction and / or transmit power of the target time unit does not meet the requirements of uplink or downlink transmission, the amplifier switches from the ON state to the OFF state.

[0233] (506) Beam ID or beam index.

[0234] For example, if the amplifier is in the ON state and the network indicates that the beam ID or beam index of the target time unit does not meet the requirements of uplink transmission or downlink transmission, the amplifier switches from the ON state to the OFF state.

[0235] (507) The transmission power of the amplifier.

[0236] For example: if the amplifier is in the ON state and the transmit power does not meet the requirements of uplink transmission or downlink transmission, the amplifier switches from the ON state to the OFF state; if the amplifier is in the OFF state and the transmit power meets the requirements of uplink transmission or downlink transmission, the amplifier switches from the OFF state to the ON state.

[0237] (508)DRX configuration information.

[0238] For example, the amplifier switches between the ON and OFF states according to the DRX configuration information. If the target time unit corresponding to the DRX configuration is ON, the amplifier is in the ON state; if the target time unit corresponding to the DRX configuration is OFF, the amplifier is in the OFF state.

[0239] (509) Terminal identification information.

[0240] For example, if the terminal identifier is an access UE of an amplifier, the amplifier is in the ON state during the target time unit; otherwise, it is in the OFF state.

[0241] (510) Load information.

[0242] For example, an amplifier changes the ratio of its ON state resources to its OFF state resources according to the size of the load. If the load is large, the ratio of its ON state resources to its OFF state resources will be large; if the load is small, the ratio of its ON state resources to its OFF state resources will be small. (511) Target resource information, wherein the target resource information includes at least one of hard resource information, soft resource information, and unavailable resource information.

[0243] For example, if the target time unit is configured as a hard resource, the amplifier is in the ON state at the target time unit; if the target time unit is configured as a soft resource, the amplifier is in the OFF state at the target time unit.

[0244] Similar to the aforementioned state configuration information, the at least one working mode may also be configured according to a predetermined dimension, and the predetermined dimension includes at least one of the following (601)-(606).

[0245] (601)UL dimension.

[0246] (602) DL dimension.

[0247] (603) Time unit dimension.

[0248] (604) Time Division Multiplexing (TDM) dimension.

[0249] (605) Frequency Division Multiplexing (FDM) Dimension.

[0250] (606) Space Division Multiplexing (SDM) dimension.

[0251] (607) A frequency domain dimension, wherein the frequency domain dimension includes at least one sub-frequency domain dimension.

[0252] (608) A time domain dimension, wherein the time domain dimension includes at least one sub-time domain dimension.

[0253] It can be understood that the relevant descriptions in the aforementioned (601)-(608) can refer to the aforementioned description of the state configuration information, and to avoid repetition, they will not be repeated here.

[0254] In this embodiment, configuring the working mode and state configuration information according to different predetermined dimensions can reduce interference and ensure wireless communication performance.

[0255] For example, if inter-cell resources are divided according to TDM, the amplifier, based on its operating mode settings, will only amplify the time domain resources managed by the donor to avoid interference with neighboring cells. Furthermore, an additional on / off function is introduced, so even if there are terminals under donor coverage that interfere with the amplifier, the terminal can still be scheduled by the donor when the amplifier is off.

[0256] like Figure 7 FIG. 1 is a flow chart of an amplifier control method 700 according to an exemplary embodiment of the present application. This method 700 may be, but is not limited to, executed by a network-side device, specifically hardware and / or software installed in the network-side device. In this embodiment, the method 700 may include at least the following steps.

[0257] S710: The network-side device sends first information and / or second information to the amplifier.

[0258] The first information is used to instruct the amplifier to determine a target state, the target state including a first state or a second state, the first state means that the amplifier amplifies and / or forwards the input signal, and the second state means that the amplifier does not amplify and / or forward the input signal; The second information is used to indicate the terminal access status to the amplifier.

[0259] As a possible implementation method, the first information includes at least one of the following: first indication information, used to indicate that the amplifier performs state switching or not; second indication information, used to indicate that the amplifier is in the first state or the second state; data scheduling information; TDD configuration information; beam information; beam identification or beam index; transmit power of the amplifier; DRX configuration information; terminal identification information; load information; target resource information, the target resource information includes at least one of hard resource information, soft resource information, and unavailable resource information; MCG configuration information; secondary cell group SCG configuration information.

[0260] As another possible implementation manner, the second information includes at least one of the following: fourth indication information, used to indicate whether there is terminal access on the amplifier; SSB configuration information; paging configuration information; CORESET configuration information; Search space configuration information; data scheduling information.

[0261] As another possible implementation manner, the terminal access state is determined by the network side device according to any one of a second measurement result, a third measurement result, a fourth measurement result, and a fifth measurement result; wherein the second measurement result is a measurement result of the terminal measuring first downlink measurement information sent by the network side device, and the first downlink measurement information is information sent by the network side device to the terminal when the amplifier is in the second state; the third measurement result is a measurement result of the network side device measuring first uplink measurement information sent by the terminal, and the first uplink measurement information is information sent by the terminal to the terminal when the amplifier is in the second state; the fourth measurement result is a measurement result of the terminal measuring second downlink measurement information sent by the network side device, and the second downlink measurement information is information sent by the network side device to the terminal when the amplifier is in the first state; the fifth measurement result is a measurement result of the network side device measuring second uplink measurement information sent by the terminal, and the second uplink measurement information is information sent by the terminal to the terminal when the amplifier is in the first state.

[0262] As another possible implementation, before the network-side device sends the second information to the amplifier, the method further includes: the network-side device sends fifth indication information to the amplifier, the fifth indication information carrying at least switching indication information for instructing the amplifier to switch to the first state or the second state, and relevant time information of the amplifier switching to the first state or the second state.

[0263] As another possible implementation manner, the relevant time information carries at least one of the following: sending time information of the first downlink measurement information; sending time information of the first uplink measurement information; sending time information of the second downlink measurement information; and sending time information of the second uplink measurement information.

[0264] It can be understood that the implementation process of each implementation method provided in this embodiment can refer to the relevant description in the aforementioned method embodiments 200-600, and the same technical effect can be obtained.
