[0001] This application belongs to the technical field of wireless communication, and specifically relates to a method for controlling an amplifier, an amplifier, and a network-side device.

Background Art

[0002] In related communication technologies, by introducing a repeater, an increase in wireless signal strength, an expansion of the cell coverage range, etc. can be achieved. For example, during a wireless communication process, in order to enhance the strength of the downlink signal reaching the terminal, the repeater can receive the downlink signal transmitted from a network-side device such as a base station and amplify it and transfer it to the terminal, or in order to enhance the strength of the uplink signal reaching the base station, the repeater can receive the uplink signal from the terminal and amplify it and transfer it to a network-side device such as a base station.

[0003] However, when the repeater introduced in the related technology is turned on and considering its continuous operation, in this case, this repeater may amplify the noise in the communication system even during a time period when there is no signal that needs to be amplified, causing interference and affecting the wireless communication performance.

Embodiments for Carrying Out the Invention

[0018] Hereinafter, while referring to the drawings in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly described. Naturally, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art also belong to the protection scope of the present application.

[0019] Terms such as "first", "second", etc. in the specification and claims of the present application are not for describing a specific order or sequence, but for distinguishing similar objects. It should be understood that such terms may be replaced with each other in appropriate cases so that the embodiments of the present application can be implemented in an order other than that illustrated or described here. Also, the objects distinguished by "first" and "second" are generally of one type, and the number of objects is not limited. For example, the first object may be one or a plurality. In the specification and claims, "and / or" indicates at least one of the connected objects, and the symbol " / " generally indicates that the related objects before and after are in an "or" relationship.

[0020] It should be noted that the technology described in the embodiments according to the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system. Furthermore, for example, it can 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 according to the present application can generally be used interchangeably. The described technology may be used in the above-mentioned systems and radio communication technologies, or in other systems and radio communication technologies. However, for the purpose of illustration in the following description, the New Radio (NR) system is described and the NR term is used in most of the following descriptions. These technologies are applicable beyond the NR system and are applicable, for example, to the 6th Generation (6G) communication system as well.

[0021] FIG. 1 shows a schematic configuration diagram of a wireless communication system applicable to an embodiment according to the present application. The wireless communication system includes a terminal 11 and a network-side device 12. Here, the terminal 11 may also be referred to as a terminal device or a user equipment (UE), and may also be a mobile phone, a tablet personal computer, a laptop computer (also called a notebook computer), a personal digital assistant (PDA), a personal digital assistant, a mobile information terminal, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), a wearable device, or an in-vehicle device (VUE), a pedestrian terminal (PUE), or other terminal-side devices. The wearable device includes a smart watch, a bracelet, earphones, glasses, etc. It is necessary to explain that the specific type of the terminal 11 is not limited in the embodiments according to the present application.The network-side device 12 may be a base station or a core network. Among them, the base station may be referred to as Node B, evolved Node B, access point, Base Transceiver Station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (ESS), B node, evolved B node (eNB), home B node, home evolved B node, Wireless Local Area Network (WLAN) access point, Wireless Fidelity (WiFi) node, Transmitting Receiving Point (TRP), or other appropriate terms in the field. If the same technical effect can be achieved, the base station is not limited to specific technical terms. In the embodiments of the present application, only the base station in the NR system is taken as an example, but it is necessary to explain that the specific type of the base station is not limited.

[0022] The amplifier can be understood as a Smart amplifier, signal amplifier, etc. In this embodiment, the amplifier may include a Mobile Termination (MT) and a Radio Unit (RU). The MT is for establishing a connection with a network-side device (such as a gNB, donor node, core network node, etc.). That is, the network-side device exchanges information with the amplifier via the MT, so that the amplifier can receive control, etc. from the network-side device. For example, the network-side device can control the transmission parameters of the amplifier, the on / off of the amplifier, the transmission beam, etc. The RU is for establishing a connection with the UE and performing signal exchange.

[0023] It should be noted that the amplifier can be understood as a network node located between the UE and the network-side device to realize processing such as amplification and transfer of uplink / downlink signals.

[0024] Hereinafter, with reference to the drawings, the technical means provided in the embodiments of the present application will be described in detail by way of several embodiments and their use cases.

[0025] FIG. 2 shows a schematic flowchart of an amplifier control method 200 provided in an exemplary embodiment of the present application. The method 200 can be executed by an amplifier, but is not limited thereto. Specifically, it can be executed by the hardware and / or software installed in the amplifier. In this embodiment, the method 200 may include at least the following steps S210 and S220.

[0026] In S210, the amplifier determines a target state based on the terminal access state and / or the first information indicated by the network-side device.

[0027] Here, the terminal access state indicates whether there is terminal access to the amplifier, that is, whether it is necessary to perform signal amplification, transfer, etc. between the terminal and / or the network-side device within the coverage range of the amplifier. In this embodiment, the terminal access state may be determined by the amplifier itself or by an instruction from the network-side device.

[0028] The first information is for instructing the amplifier of its state. For example, it indicates whether a state switch is necessary, and further, for example, the target state that the amplifier should switch to.

[0029] Naturally, the target state may include a first state or a second state. The first state indicates that the amplifier (for example, the RU part) amplifies and / or transfers an input signal (for example, a signal transmitted from a terminal or a network-side device). Here, the first state can be understood as an ON state, and may include a power-on state, a state where the RU normally amplifies or transmits an input signal, etc.

[0030] The second state indicates that the amplifier does not amplify and / or transfer an input signal (for example, a signal transmitted from a terminal or a network-side device). Here, the second state can be understood as an OFF state and may include at least one of an RU sleep state, a low output power state, and a power-off state.

[0031] It should be noted that depending on the communication design, the low amplification multiple state in the amplifier may belong to the second state or may belong to the first state, and is not limited here.

[0032] In S220, the amplifier performs a state switch based on the target state.

[0033] As understood, when the amplifier performs a state switch based on 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.

[0034] In this embodiment, the amplifier determines the target state based on the terminal state information and the first information instructed by the network-side device, and then performs a state switch based on the target state. Thereby, when the amplifier does not need to transfer or amplify a signal, it can switch between the first state and the second state, so as to achieve the purpose of power saving, reduce the interference caused by noise amplification in the wireless communication system, and ensure the wireless communication quality.

[0035] For example, assuming a time period when there is no signal that needs to be amplified in the amplifier, the amplifier can switch to the second state (i.e., the OFF state), thereby avoiding the amplification of interference signals and noise in other cells, ensuring the signal reception quality of this cell, or avoiding transmitting the side lobe and noise signal of the signal transmitted from this cell to other cells, and ensuring the signal reception quality of other cells.

[0036] FIG. 3 shows a schematic flowchart of an amplifier control method 300 provided in an exemplary embodiment of the present application. Although the method 300 can be executed by an amplifier, it is not limited thereto. Specifically, it can be executed by hardware and / or software implemented in the amplifier. In this embodiment, the method 300 may include at least the following step S310.

[0037] In S310, the amplifier determines a target state based on first information instructed by a network-side device.

[0038] As can be understood, for the realization process of S310, in addition to referring to the related description in method embodiment 200, as a possible implementation form, the first information may include at least one item of the following (101)-(113).

[0039] (101) First indication information for instructing the amplifier to perform state switching or not to perform state switching.

[0040] Here, 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.

[0041] Taking DCI as an example, the network-side device can explicitly or implicitly instruct the amplifier to switch or not to switch by DCI. For example, one code point in DCI can be used to instruct the amplifier to perform state switching, and another code point can be used to instruct the amplifier not to perform state switching.

[0042] Furthermore, for example, the amplifier can be instructed by one code point in the DCI to perform a state transition. For example, the amplifier can switch from the ON state to the OFF state, or from the OFF state to the ON state.

[0043] (102) Second indication information for indicating whether the amplifier is in the first state or the second state.

[0044] Here, similar to the first indication information, the second indication information may be DCI, MAC CE, SFI, RRC signaling, etc.

[0045] Here, taking DCI as an example again, the network-side device can indicate whether the amplifier is in the first state or the second state in an explicit or implicit manner.

[0046] For example, one code point in the DCI can be used to indicate that the amplifier is in the first state, and another code point can be used to indicate that the amplifier is in the second state.

[0047] Furthermore, for example, one code point in the DCI can be used to indicate that the amplifier is in the first state 1 (corresponding to DRX configuration 1), another code point can be used to indicate that the amplifier is in the first state 2 (corresponding to DRX configuration 2), and yet another code point can be used to indicate that the amplifier is in the second state.

[0048] Furthermore, for example, one code point can be used to indicate that the amplifier is in the first state 1 (corresponding to amplification factor alpha 1), another code point can be used to indicate that the amplifier is in the first state 2 (corresponding to amplification factor alpha 2), and yet another code point can be used to indicate that the amplifier is in the second state.

[0049] In addition, when the second indication information is used to indicate whether the amplifier is in the first state or the second state, the indication method may include at least one of the following (1021)-(1024).

[0050] (1021) Indicate that the resource in the downlink (DL) time unit of the amplifier is in the ON state (i.e., the first state).

[0051] (1022) Indicate that the resource in the uplink (UL) time unit of the amplifier is in the ON state.

[0052] (1023) Indicate that the resource in the flexible time unit of the amplifier is in the ON state when at least some of the following conditions (a)-(e) are satisfied. (a) There is a semi-persistent UL / DL configuration in the flexible time unit. (b) There is dynamic UL / DL scheduling in the flexible time unit. (c) There is dynamic indication information of the base station in the flexible time unit. (d) There is scheduling of the Physical Random Access Channel (PRACH), Physical Uplink Control Channel (PUCCH), etc. in the flexible time unit. (e) There is scheduling of at least one of the Channel State Information Reference Signal (CSI-RS), Synchronization Signal Block (SSB), and common search space (CSS) in the flexible time unit.

[0053] When the amplifier is in an unavailable (Not Available, NA) resource (which may be a time-domain resource and / or a frequency-domain resource), it is instructed to be in the OFF state.

[0054] Optionally, the time units described in this embodiment and the following embodiments may be sub-slots, slots, sub-frames, frames, symbols, seconds (s), milliseconds (ms), etc., but are not limited thereto.

[0055] (103) Data scheduling information.

[0056] Here, the data scheduling information is used to schedule UL data, DL data, etc.

[0057] According to this, when the first information includes data scheduling information, the step of the amplifier determining the target state based on the data scheduling information instructed by the network-side device may include at least one of the following (1031)-(1033).

[0058] (1031) When the scheduling data instructed by the data scheduling information is UL data and / or DL data, it is determined that the target state is the first state (i.e., the ON state).

[0059] For example, at time unit n, when the scheduling data instructed by the data scheduling information is UL data and / or DL data, the state of the amplifier at time unit n is the first state, i.e., the ON state.

[0060] (1032) When the data scheduling information is not scheduling UL data and DL data, it is determined that the target state is the second state.

[0061] For example, when the data scheduling information does not schedule UL data and DL data in time unit n, the state of the amplifier at time unit n is the second state, i.e., the OFF state.

[0062] (1033) When the scheduling data indicated by the data scheduling information is predetermined data including at least one of PRACH, PUCCH, Sounding Reference Signal (SRS), CSI-RS, SSB, CSS (for example, type 1 CSS), it is determined that the target state is the first state.

[0063] (104) Time Division Duplexing (TDD) configuration information.

[0064] Here, when the first information includes TDD configuration information, the step of the amplifier determining the target state based on the TDD configuration information indicated by the network-side device may include at least one of the following (1041)-(1043).

[0065] (1041) When the TDD configuration includes a UL configuration and / or a DL configuration, it is determined that the target state is the first state.

[0066] For example, when the TDD configuration includes a UL configuration and / or a DL configuration in time unit n, the state of the amplifier at time unit n may be the first state, i.e., the ON state.

[0067] (1042) When the TDD configuration includes a flexible configuration, it is determined that the target state is the second state.

[0068] For example, when the TDD configuration includes a flexible configuration in time unit n, the state of the amplifier at time unit n is the second state, i.e., the OFF state.

[0069] Determine the target state based on the configuration ratio of the TDD, which is a ratio between a first configuration including a (1043) UL configuration and / or a DL configuration and a second configuration including a flexible configuration.

[0070] For example, when the ratio is greater than a second threshold, determine that the target state is the first state; when the ratio is not greater than the second threshold, determine that the target state is the second state. Here, the second threshold can be realized by protocol regulations, upper layer configurations, or network configurations.

[0071] (105) Beam information.

[0072] Here, the beam information may be a beam direction, the number of beams, etc.

[0073] (106) Beam identifier (ID) or beam index.

[0074] For example, for (105) and (106), when the traffic load information is included in the first information, by default, determine that the target state is the first state; conversely, by default, determine that the target state is the second state.

[0075] (107) Transmission power of the amplifier.

[0076] For example, when the transmission power of the amplifier is greater than a second threshold, determine that the target state is the first state; when the transmission power of the amplifier is not greater than a third threshold, determine that the target state is the second state. Here, the third threshold can be realized by protocol regulations, upper layer configurations, or network configurations.

[0077] (108) Discontinuous Reception (DRX) configuration information.

[0078] For example, when the DRX configuration information is DRX configuration 1 or DRX configuration 2, it is determined that the target state is the first state.

[0079] (109) Terminal identifier information.

[0080] For example, when the terminal corresponding to the terminal identifier information is a terminal covered by the amplifier, it is determined that the target state is the first state, and conversely, it is determined that the target state is the second state.

[0081] Furthermore, for example, when the terminal identifier information is included in the first information, it is defaulted that the target state is the first state, and conversely, it is determined that the target state is the second state by default.

[0082] (110) Traffic load information.

[0083] For example, when the traffic load information is greater than a third threshold, it is determined that the target state is the first state, and conversely, it is determined that the target state is the second state.

[0084] Furthermore, for example, when the traffic load information is included in the first information, it is defaulted that the target state is the first state, and conversely, it is determined that the target state is the second state by default.

[0085] (111) Target resource information including at least one of hard resource information, soft resource information, and unavailable resource information.

[0086] Here, when the first information is the target resource information, the step of determining the target state based on the target resource information indicated by the amplifier by the network-side device includes at least one of the following (1111)-(1113).

[0087] When the target resource information is the hardware resource, determine that the target state is the first state.

[0088] When the target resource information is the unavailable resource, determine that the target state is the second state.

[0089] When the target resource information is the software resource, determine that the target state is the second state or the first state.

[0090] Here, when the target resource information is the software resource, it represents DRX configuration 1, or represents the amplification multiple alpha1, or represents an undetermined first state or second state.

[0091] According to this, as a possible implementation form, when the target resource information is the software resource, and the third indication information for indicating whether the amplifier is in the first state or the second state transmitted from the network side device is received, determine the target state based on the third indication information, and / or when the target resource information is the software resource, by default, determine that the target state is the second state.

[0092] As an example, when the soft resource information represents an undetermined first state and second state, a network side device such as a base station can dynamically indicate by the third indication information that the amplifier is in the first state or the second state in the soft resource. When the base station does not dynamically indicate that the amplifier is in the first state in the soft resource, by default, determine that the amplifier is in the second state.

[0093] (112) Master Cell Group (MCG) configuration information.

[0094] (113) Secondary Cell Group (SCG) configuration information.

[0095] Here, when the first information includes MCG configuration information and / or SCG configuration information (that is, when the amplifier is in a dual-connection state), the step of the amplifier determining a target state based on the MCG configuration information and / or the SCG configuration information instructed by the network-side device includes at least one of the following (1131)-(1132).

[0096] (1131) When both the MCG configuration information and the SCG configuration information indicate that the state of the amplifier is the second state, it is determined that the target state is the second state.

[0097] (1132) When the MCG configuration information or the SCG configuration information indicates that the state of the amplifier is the first state, it is determined that the target state is the first state.

[0098] Also, as a possible implementation form, the amplifier may determine the target state only based on the MCG configuration information. For the determination process, reference can be made to related implementation forms such as the above-mentioned (101)-(111), and in order not to repeat the description, it is not limited here.

[0099] As another possible implementation form, the MCG configuration information and the SCG configuration information can not only indicate the operating state of the amplifier, but also indicate the operating time, operating frequency, etc. of the amplifier. Regarding this, the following will be described with reference to (1133)-(1137).

[0100] (1133) When the MCG configuration information indicates that the operating time range of the amplifier is the first time range and the SCG configuration information indicates that the operating time range of the amplifier is the second time range, the operating time range of the amplifier is the sum of the first time range and the second time range.

[0101] For example, assuming that the first time range is (T1, T2) and the second time range is (T2, T3), the operating time range of the first amplifier is (T1, T2, T3).

[0102] (1134) When the MCG configuration information indicates that the operating time range of the amplifier is the first time range, and the SCG configuration information indicates that the operating time range of the amplifier is the second time range, the operating time range of the amplifier is the overlapping part of the first time range and the second time range.

[0103] For example, assuming that the first time range is (T1, T2) and the second time range is (T2, T3), the operating time range of the first amplifier is (T2).

[0104] (1135) When the configuration information of the MCG indicates that the operating frequency range of the amplifier is the first frequency range, and the configuration information of the SCG indicates that the operating frequency range of the amplifier is the second frequency range, the operating frequency range of the amplifier is the sum of the first frequency range and the second frequency range.

[0105] For example, assuming that the first frequency range is (F1, F2) and the second frequency range is (F2, F3), the operating frequency range of the first amplifier is (F1, F2, F3).

[0106] (1136) When the configuration information of the MCG indicates that the operating frequency range of the amplifier is the first frequency range, and the configuration information of the SCG indicates that the operating frequency range of the amplifier is the second frequency range, the operating frequency range of the amplifier is the overlapping part of the first frequency range and the second frequency range.

[0107] For example, assuming that the first frequency range is (F1, F2) and the second frequency range is (F2, F3), the operating frequency range of the first amplifier is (F2).

[0108] (1137) 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. When 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 of 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.

[0109] In addition to the above-mentioned (1133)-(1137), when the MCG configuration information and the SCG configuration information are different, the amplifier can determine the operating frequency range of the RU part only according to the SCG configuration information. However, when the amplifier obtains the SCG configuration information but does not operate within a predetermined period, the amplification / transfer, etc. of the SCG frequency band by the amplifier may be temporarily stopped.

[0110] Based on the above-described implementation forms, when transmitting the first information by the fifth information, it should be noted that at least one of the start time, end time, and duration of the target state of the amplifier may be included in the fifth information.

[0111] Also, the activation time of the fifth information can be determined by the first time unit and the first numerical value for receiving the fifth information, or the activation time of the fifth information is determined based on the seventh instruction information transmitted from the network-side device.

[0112] For example, assuming that the first numerical value is L and the amplifier receives the fifth information at time unit n, the activation time of the first information indicated by the fifth information may be time unit n + L.

[0113] Furthermore, for example, assuming that the first numerical value is L and the amplifier uses the first information indicated by the fifth information at time unit n, the reception time unit of the fifth information may be time unit n - L.

[0114] Optionally, the first numerical value is related to the subcarrier spacing (SCS), or the first numerical value is realized by an indication from the network side, a regulation by a protocol, an arrangement by a higher layer, etc., for example, realized by an indication by the fifth piece of information, and is not limited herein.

[0115] As can be understood, when the first numerical value is related to the SCS, the relationship between the first numerical value and the SCS can be defined in advance. For example, when SCS = 15 kHz, the first numerical value is K1; when SCS = 30 kHz, the first numerical value is K2; when SCS = 60 kHz, the first numerical value is K3; when SCS = 120 kHz, the first numerical value is K4. In this case, when it is necessary to determine the activation time of the fifth piece of information, the first numerical value can be determined based on the above-defined relationship between the first numerical value and the SCS.

[0116] It should be noted that for the activation time of the following second piece of information or other indication information, the description of the activation time of the above fifth piece of information can be referred to, and for the sake of not repeating the description, the detailed description is omitted here. In S320, the amplifier performs a state switch based on the target state. As can be understood, for the implementation process of S320, reference can be made to the relevant description in Method Embodiment 200, and similar technical effects are achieved. To avoid repeated explanations, detailed descriptions are omitted here.

[0117] In this embodiment, the amplifier determines and switches the target state according to the first piece of information indicated by the network-side device, so it can perform signal transfer, amplification, etc. that are effective in the first state, and reduce interference in the system and ensure wireless communication quality in the second state.

[0118] FIG. 4a shows a schematic flowchart of an amplifier control method 400 provided in an exemplary embodiment of the present application. The method 400 can be executed by an amplifier, but is not limited thereto. Specifically, it can be executed by hardware and / or software installed in the amplifier. In this embodiment, the method 400 may include at least the following steps S410, step S420, and step S430.

[0119] In S410, the amplifier determines the terminal access state based on second information instructed by the network-side device.

[0120] Here, it should be noted that when the network-side device instructs the amplifier of the terminal access state by the second information, the second information may include at least one of the following (201)-(206).

[0121] (201) Fourth indication information for instructing whether there is terminal access in the amplifier.

[0122] Here, the fourth indication information may be DCI, RRC, MAC CE, etc.

[0123] Taking DCI as an example, the network-side device can instruct the terminal access state in an explicit or implicit manner by DCI.

[0124] For example, one code point indicates that the terminal access state is a state where there is terminal access in the amplifier, and another code point indicates that the terminal access state is a state where there is no terminal access in the amplifier.

[0125] (202) SSB configuration information.

[0126] Here, when the amplifier can detect the SSB information transmitted from the terminal or the network-side device, the amplifier considers that there is UE access, and when the SSB information cannot be detected, it considers that there is no terminal access.

[0127] (203) Paging configuration information.

[0128] Here, when the amplifier can detect the paging information transmitted from the network side or the terminal at the paging position, the amplifier considers that there is a UE access. When the amplifier cannot detect the paging information, it considers that there is no terminal access.

[0129] (204) Control resource set (CORESET) configuration information.

[0130] Here, when the amplifier can detect the control information transmitted from the network side or the UE at the CORESET position, the amplifier considers that there is a UE access. When the amplifier cannot detect the control information, it considers that there is no terminal access.

[0131] (205) Search space configuration information.

[0132] Here, when the amplifier can detect the control information transmitted from the network side or the terminal at the search space position where the amplifier is arranged, the amplifier considers that there is a terminal access. When the amplifier cannot detect the control information, it considers that there is no terminal access.

[0133] (206) Data scheduling information.

[0134] Here, when the amplifier can detect the scheduling information on the network side or the data transmission of the terminal, the amplifier considers that there is a UE access. When the amplifier cannot detect it, it considers that there is no terminal access.

[0135] Or, when the scheduling data indicated by the data scheduling information is UL data and / or downlink DL data, the amplifier determines the state where there is a terminal access as the terminal access state.

[0136] Or, when the data scheduling information is not scheduling UL data and DL data, the amplifier determines the state where there is no terminal access as the terminal access state.

[0137] In one implementation form, the second information may be determined by any one of the second measurement result, the third measurement result, the fourth measurement result, and the fifth measurement result by the network-side device and then transmitted to the amplifier.

[0138] Here, the second measurement result is a measurement result obtained by the terminal measuring the first downlink measurement information transmitted from the network-side device, and the first downlink measurement information is information transmitted by the network-side device to the terminal when the amplifier is in the second state.

[0139] The third measurement result is a measurement result obtained by the network-side device measuring the first uplink measurement information transmitted from the terminal, and the first uplink measurement information is information transmitted by the terminal to the network-side device when the amplifier is in the second state.

[0140] The fourth measurement result is a measurement result obtained by the terminal measuring the second downlink measurement information transmitted from the network-side device, and the second downlink measurement information is information transmitted by the network-side device to the terminal when the amplifier is in the first state.

[0141] The fifth measurement result is a measurement result obtained by the network-side device measuring the second uplink measurement information transmitted from the terminal, and the second uplink measurement information is information transmitted by the terminal to the network-side device when the amplifier is in the first state.

[0142] In this case, in order to avoid the influence of the amplifier on the second measurement result, the third measurement result, the fourth measurement result, and the fifth measurement result, and ensure the accuracy of the measurement result, before the amplifier determines the terminal access state based on the second information instructed by the network-side device, the amplifier can further receive the fifth instruction information transmitted from the network-side device. Here, the fifth instruction information includes at least a switching command for instructing the amplifier to switch to the first state or the second state, and / or related time information which is the time information for the amplifier to switch to the first state or the second state. Thereby, the amplifier can perform state switching based on the switching command and / or the related time information.

[0143] Optionally, regarding the related time information, the network-side device notifies the amplifier of the setting information of the measurement signal, and the amplifier turns off or on at the corresponding time. According to this, in this embodiment, the related time information may include at least one of the transmission time information of the first downlink measurement information, the transmission time information of the first uplink measurement information, the transmission time information of the second downlink measurement information, and the transmission time information of the second uplink measurement information. Also, depending on the measurement requirement, the related time information may further include at least one of the start time, the end time, and the duration of the first state or the second state.

[0144] As a possible implementation form, the related time information may be indicated by the on / off pattern shown in FIG. 4b, and the on / off pattern is used when the amplifier is in the activated / started state.

[0145] According to this, assuming that the network-side device is a donor node, this embodiment will explain the determination process of the second measurement result, the third measurement result, the fourth measurement result, and the fifth measurement result as follows by different examples.

[0146] In Example 1, the donor node instructs, according to the fifth piece of indication information, the temporary off-time range of the amplifier. In the off-time range of the amplifier, the donor transmits a downlink measurement signal (e.g., aperiodic CSI-RS) to at least one terminal covered by the amplifier. Subsequently, the donor node determines, based on the measurement result reported by the terminal (i.e., the second measurement result), whether it is necessary to turn off at least the downlink amplification of the amplifier, that is, whether there is a terminal access, and transmits the determination result to the amplifier as the second piece of information.

[0147] In Example 2, the donor node instructs, according to the fifth piece of indication information, the temporary off-time range of the amplifier. In the off-time range of the amplifier, the donor instructs the UE to transmit an uplink measurement signal (e.g., periodic SRS, semi-persistent SRS, aperiodic SRS) to at least one donor covered by the amplifier. The donor determines, based on the measurement result (i.e., the third measurement result), whether it is necessary to turn off at least the uplink amplification of the amplifier, that is, whether there is a terminal access, and transmits the determination result to the amplifier as the second piece of information.

[0148] In Example 3, the donor node instructs, according to the fifth piece of indication information, the temporary on-time range of the amplifier. In the on-time range of the amplifier, the donor transmits a downlink measurement signal (e.g., SSB, CSI-RS) to at least one terminal covered by the amplifier. The donor determines, based on the measurement result reported by the terminal (i.e., the fourth measurement result), whether it is necessary to turn on at least the downlink amplification of the amplifier, that is, whether there is a terminal access, and transmits the determination result to the amplifier as the second piece of information.

[0149] In Example 4, the donor node instructs, according to the fifth indication information, the temporary on-time range of the amplifier. In the on-time range of the amplifier, the donor instructs the UE to transmit an uplink measurement signal (e.g., periodic SRS, semi-persistent SRS, aperiodic SRS) to at least one donor covered by the amplifier. The donor determines, according to the measurement result (i.e., the fifth measurement result), whether it is necessary to turn on at least the uplink amplification of the amplifier, that is, whether there is a terminal access, and transmits the determination result to the amplifier as the second information.

[0150] In S420, the amplifier determines a target state based on the terminal access state.

[0151] As can be understood, for the implementation process of S420, in addition to referring to the relevant descriptions in Method Embodiments 200 and 300, as a possible implementation form, referring to FIG. 4a again, the implementation process of S420 may further include S421 and / or S422, and the content is as follows.

[0152] In S421, when the terminal access state is a state where there is terminal access to the amplifier, it is determined that the target state is the first state.

[0153] That is, when there is a terminal and / or network-side device that needs to perform information transmission within the coverage range of the amplifier, the amplifier switches to the ON state or maintains the ON state.

[0154] In S422, when the terminal access state is a state where there is no terminal access to the amplifier, it is determined that the target state is the second state.

[0155] That is, when there is no terminal and / or network-side device that needs to perform information transmission within the coverage range of the amplifier, the amplifier switches to the OFF state or maintains the OFF state.

[0156] In S430, the amplifier performs a state switch based on the target state.

[0157] As can be understood, for the implementation process of S430, reference can be made to the relevant descriptions in Method Embodiments 200 - 400. Similar technical effects are achieved, and to avoid repeated explanations, detailed descriptions are omitted here.

[0158] In this embodiment, the amplifier determines the terminal access state according to the second information, and then determines and switches the target state based on the terminal access state. Therefore, effective signal transfer, amplification, etc. can be performed in the first state, and interference within the system can be reduced in the second state, ensuring the quality of wireless communication.

[0159] FIG. 5 shows a schematic flowchart of an amplifier control method 500 provided in an exemplary embodiment of the present application. The method 500 can be executed by an amplifier, but is not limited thereto. Specifically, it can be executed by hardware and / or software installed in the amplifier. In this embodiment, the method 500 may include at least the following steps S510, step S520, and step S530.

[0160] In S510, the amplifier determines the terminal access state according to the first measurement result for the third information.

[0161] Here, the third information may be uplink measurement information transmitted from a terminal covered by the amplifier or downlink measurement information transmitted from a network - side device. For example, in this embodiment, the third information may include at least one item of at least SRS, PRACH, Physical Uplink Shared Channel (PUSCH), PUCCH, and Demodulation Reference Signal (DMRS).

[0162] As a possible implementation form, the step of the amplifier determining the terminal access state according to the first measurement result of the third piece of information includes at least one of the following (301)-(304). (301) When the uplink signal cannot be measured as the first measurement result, determine that there is no terminal access to the amplifier as the terminal access state. (302) When the first measurement result is smaller than the first threshold, determine that there is no terminal access to the amplifier as the terminal access state. (303) When the first measurement result is greater than or equal to the first threshold, determine that there is terminal access to the amplifier as the terminal access state. (304) When the uplink signal is measured as the first measurement result, determine that there is terminal access to the amplifier as the terminal access state.

[0163] Here, the first threshold can be determined by protocol regulations, upper layer signaling configuration, network side configuration, etc., and is not limited here.

[0164] Also, the measurement time for the amplifier to measure the third piece of information can also be realized by protocol regulations, upper layer configuration, network indication, or network configuration, etc. For example, the amplifier can receive the sixth piece of information carrying the measurement time activation information and / or measurement time indication information transmitted from the network side device, and the amplifier further determines the target measurement time based on the measurement time activation information and / or the measurement time indication information, measures the third piece of information based on the target measurement time, and obtains the first measurement result.

[0165] Here, the measurement time can be arranged periodically or semi-persistently and periodically, and the sixth indication information may be a DCI activation indication or a wake-up signal (WUS), etc. The detection time of the sixth indication information (which may also be understood as the detection time of the measurement time activation information or the measurement time indication information) can be realized by means such as protocol regulations, upper layer arrangements, or network arrangements.

[0166] For example, the network-side device can arrange a semi-persistent detection period and determine the activation time of the measurement time by means of a DCI activation command. When the DCI is activated, the amplifier performs the measurement of the third information within the next arranged detection period.

[0167] Furthermore, for example, the network-side device arranges a semi-persistent detection period and a dynamic activation indication detection time, so that the amplifier can monitor the dynamic indication signaling DCI within the dynamic activation indication detection time. When the dynamic indication signaling DCI (that is, one WUS signaling) is detected, the amplifier switches to the ON state.

[0168] Also, as one implementation form, when the measurement time activation information is carried in the sixth indication information and the amplifier is in the second state, the amplifier switches to the first state.

[0169] In S520, the amplifier determines a target state based on the terminal access state.

[0170] In S521, when the terminal access state is a state where there is terminal access to the amplifier, it is determined that the target state is the first state.

[0171] In S522, when the terminal access state is a state where there is no terminal access to the amplifier, it is determined that the target state is the second state.

[0172] In S530, the amplifier performs a state switch based on the target state.

[0173] As can be understood, for the implementation processes of S520, S521, S522, and S530, reference can be made to the relevant descriptions in Method Embodiments 200-400. Similar technical effects are achieved, and to avoid repeated explanations, detailed descriptions are omitted here.

[0174] In this embodiment, the amplifier determines the terminal access state according to the first measurement result, and then determines and switches the target state based on the terminal access state. Therefore, effective signal transfer and amplification, etc. are performed in the first state, and interference within the system is reduced in the second state, ensuring the wireless communication quality.

[0175] FIG. 6a shows a schematic flowchart of a method for controlling an amplifier provided in an exemplary embodiment of the present application. The method 600 can be executed by the amplifier, but is not limited thereto. Specifically, it can be executed by the hardware and / or software installed in the amplifier. In this embodiment, the method 600 may include at least the following steps S610, step S620, step S630, step S640, and step S650.

[0176] In S610, when at least one state configuration information is arranged for the amplifier, target configuration information is determined based on the at least one state configuration information.

[0177] Here, the state determination rule of the amplifier is arranged in the state arrangement information. For example, in the state arrangement information, whether the amplifier determines the target state based on the terminal access state, determines the target state based on the first information indicated by the network-side device, determines the target state based on both the terminal access state and the first information indicated by the network-side device, or parameters such as the time when the amplifier determines the target state and the state switching timing involved in the target state determination process may be arranged. This embodiment is not limited thereto.

[0178] In one implementation form, the at least one state arrangement information can be arranged in a predetermined dimension. Here, the predetermined dimension may include at least one item of the following (401)-(408).

[0179] (401) UL dimension.

[0180] (402) DL dimension.

[0181] (403) Time unit dimension.

[0182] Here, for the above (401)-(403), it can be understood that one set of state arrangement information can be arranged independently based on the UL dimension and / or one set of state arrangement information can be arranged independently based on the DL dimension. In this embodiment, considering the UL / DL asymmetry, one set of state arrangement information may be arranged based on the time unit without considering the UL / DL arrangement.

[0183] (404) Time division multiplexing (TDM) dimension.

[0184] (405) Frequency division multiplexing (FDM) dimension.

[0185] (406) Space division multiplexing (SDM) dimension.

[0186] Here, for (404)-(406), it can be understood that one set of state arrangement information is arranged independently based on the TDM dimension, one set of state arrangement information is arranged independently based on the FDM dimension, and one set of state arrangement information is arranged independently based on the SDM dimension.

[0187] In this case, the amplifier can use corresponding arrangements according to the multiplexing method. For example, when the multiplexing method is TDM, the state arrangement information arranged based on the TDM dimension can be used.

[0188] (407) A frequency domain dimension including at least one sub-frequency domain dimension.

[0189] That is, one set of state arrangement information is arranged independently for each frequency range (Per frequency range).

[0190] (408) A time domain dimension including at least one sub-time domain dimension.

[0191] That is, one set of state arrangement information is arranged independently for each time range (Per time range).

[0192] It should be noted that the state arrangement information arranged based on different dimensions in the above (401)-(408) may be used in combination or alone, and is not limited here.

[0193] In S620, the amplifier determines a target state based on the terminal access state and / or the first information instructed by the network-side device.

[0194] As can be understood, for the implementation process of S620, in addition to referring to the relevant descriptions in Method Embodiments 200-500, as a possible implementation form, referring to FIG. 6a again, for the implementation process of S620, S621 may also be referred to, and the content is as follows.

[0195] In S621, based on the target configuration information, the amplifier determines the target state based on the terminal access state and / or the first information indicated by the network-side device.

[0196] Here, depending on the target configuration information, the realization process of S621 is different. For example, assuming that the target configuration information arranges that the amplifier determines the terminal access state based on the first measurement result and determines the target state based on the terminal access state, when the amplifier determines the target state, it should determine the terminal access state based on the first measurement result and then determine the target state based on the terminal access state.

[0197] In S630, the amplifier performs a state switch based on the target state.

[0198] Here, the target state includes a first state in which the amplifier amplifies and / or transfers an input signal, or a second state in which the amplifier does not amplify and / or transfer an input signal.

[0199] As can be understood, for the realization process of S630, reference can be made to the relevant descriptions in Method Embodiments 200-500, and detailed descriptions are omitted here so as not to repeat.

[0200] In S640, when the amplifier is in the second state but needs to transfer and / or amplify a signal transmitted from a target device, the amplifier switches from the second state to the first state.

[0201] Here, the target device is a terminal and / or a network-side device covered by the amplifier. That is, for an amplifier in the OFF state, when it is necessary to transfer and amplify a signal between a terminal and / or a network-side device within the coverage range of the amplifier, the amplifier can switch from the OFF state to the ON state to perform signal transfer and amplification.

[0202] As a possible implementation form, when the amplifier receives the fourth piece of information transmitted from the network-side device, it can determine whether to transfer and / or amplify the signal transmitted from the target device based on the fourth piece of information. Here, for the determination process of the fourth piece of information, reference can be made to the description of the determination process of the second piece of information above. In order not to repeat the description, a detailed description is omitted here.

[0203] In S650, when the amplifier switches to the first state, the amplifier performs signal amplification based on the first operation pattern.

[0204] Here, at least one operation pattern is arranged for the amplifier, and at least one amplification multiple of the amplifier is arranged for each operation pattern. Different amplification multiples correspond to different time domain information and / or frequency domain information, and the first operation pattern belongs to the at least one operation pattern.

[0205] As an example, referring to FIG. 6b, assuming that "on" represents that the amplifier operates in a preset operation pattern and "off" represents that the amplifier is turned off, various operation patterns can be set. And when the first condition is satisfied, the amplifier can switch the pattern. For example, the amplifier switches from the first operation pattern (for example, pattern #1 shown in FIG. 6c) to the second operation pattern (for example, pattern #2 shown in FIG. 6c), and the second operation pattern is another operation pattern other than the first operation pattern among the at least one operation pattern.

[0206] Optionally, the first condition can be determined by at least one of the following (501)-(511).

[0207] (501) A pattern switching instruction transmitted from the network-side device.

[0208] For example, when the amplifier is in the ON state and the network device is instructed to switch patterns, the amplifier switches from the ON state to the OFF state. When the amplifier is in the OFF state and the network device is instructed to switch patterns, the amplifier switches from the OFF state to the ON state. When the amplifier is in the ON state and the network device is instructed not to switch, the amplifier maintains the ON state. When the amplifier is in the OFF state and the network device is instructed not to switch, the amplifier maintains the OFF state.

[0209] (502) The operation time of the first operation pattern.

[0210] For example, when the duration of the amplifier being in the ON state is greater than a first predetermined value, the amplifier switches to the ON state. Or when the duration of the amplifier being in the OFF state is greater than a second predetermined value, the amplifier switches to the OFF state.

[0211] (503) Data scheduling information.

[0212] For example, when the terminal or the amplifier is arranged or instructed to perform uplink transmission or downlink transmission in target time units, the amplifier is in the ON state in target time units. When the terminal or the amplifier is arranged or instructed not to perform scheduling transmission in target time units, the amplifier is in the OFF state in target time units.

[0213] (504) TDD configuration information.

[0214] For example, when 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. When the TDD configuration information indicates that the target time unit is a flexible time unit, the amplifier is in the OFF state.

[0215] (505) Beam information.

[0216] For example, when the amplifier is in the ON state and the network side indicates that the beam direction and / or transmission power per target time unit do not meet the requirements of uplink transmission or downlink transmission, the amplifier switches from the ON state to the OFF state.

[0217] (506) Beam ID or beam Index.

[0218] For example, when the amplifier is in the ON state and the network side indicates that the beam ID or beam index per 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.

[0219] (507) Transmission power of the amplifier.

[0220] For example, when the amplifier is in the ON state and the transmission power does not meet the requirements of uplink transmission or downlink transmission, the amplifier switches from the ON state to the OFF state. When the amplifier is in the OFF state and the transmission power meets the requirements of uplink transmission or downlink transmission, the amplifier switches from the OFF state to the ON state.

[0221] (508) DRX configuration information.

[0222] For example, the amplifier switches between the ON state and the OFF state based on the DRX configuration information. When the target time unit corresponding to the DRX configuration is on, the amplifier is in the ON state. When the target time unit corresponding to the DRX configuration is off, the amplifier is in the OFF state.

[0223] (509) Terminal identifier information.

[0224] For example, when the terminal identifier is a UE accessing the amplifier, the amplifier is in the ON state per target time unit, and vice versa, it is in the OFF state.

[0225] (510) Traffic load information.

[0226] For example, the amplifier changes the ratio of the ON-state resources to the OFF-state resources of the amplifier according to the magnitude of the traffic load. When the traffic load is large, the ratio of the ON-state resources to the OFF-state resources is large, and when the traffic load is small, the ratio of the ON-state resources to the OFF-state resources is small.

[0227] (511) Target resource information including at least one of hard resource information, soft resource information, and unavailable resource information.

[0228] For example, when the target time unit allocation is a hard resource, the amplifier is in the ON state for the target time unit, and when the target time unit allocation is a soft resource, the amplifier is in the OFF state for the target time unit.

[0229] Similar to the above state allocation information, the at least one operation pattern can also be allocated according to a predetermined dimension, and the predetermined dimension includes at least one of the following (601)-(608). (601) UL dimension. (602) DL dimension. (603) Time unit dimension. (604) Time division multiplexing TDM dimension. (605) Frequency division multiplexing FDM dimension. (606) Space division multiplexing SDM dimension. (607) Frequency domain dimension including at least one sub-frequency domain dimension. (608) Time domain dimension including at least one sub-time domain dimension.

[0230] As can be understood, for the related descriptions in the above (601)-(608), the descriptions related to the above state allocation information can be referred to, and for the sake of not repeating the explanation, the detailed explanation is omitted here.

[0231] In this embodiment, by allocating the operation pattern and the state allocation information according to the predetermined dimension, interference can be reduced and wireless communication performance can be ensured.

[0232] For example, when distinguishing inter-cell resources by TDM, the amplifier amplifies only the time-domain resources managed by the donor according to the operation pattern setting, avoiding interfering with adjacent cells. At the same time, since On / Off is introduced separately, even when there is a terminal interfered by the amplifier within the coverage range of the donor, the terminal can be scheduled to the donor when the amplifier is in the off state.

[0233] FIG. 7 shows a schematic flowchart of an amplifier control method 700 provided in an exemplary embodiment of the present application. The method 700 can be executed by a network-side device, but is not limited thereto, and can specifically be executed by hardware and / or software implemented in the network-side device. In this embodiment, the method 700 may include at least the following step S710.

[0234] In S710, the network-side device transmits first information and / or second information to the amplifier.

[0235] Here, the first information is for instructing the amplifier to determine a target state, and the target state includes a first state in which the amplifier amplifies and / or transfers an input signal, or a second state in which the amplifier does not amplify and / or transfer the input signal. The second information is for instructing the amplifier about the terminal access state.

[0236] As a possible implementation form, the first information includes at least one of first instruction information for instructing the amplifier to perform state switching or not to perform state switching, second instruction information for instructing whether the amplifier is in a first state or a second state, data scheduling information, TDD configuration information, beam information, beam identifier or beam index, transmission power of the amplifier, DRX configuration information, terminal identifier information, traffic load information, hard resource information, soft resource information, target resource information including unavailable resource information, MCG configuration information, and at least one of secondary cell group SCG configuration information.

[0237] As another possible implementation form, the second information includes at least one of fourth instruction information for instructing whether there is terminal access to the amplifier, SSB configuration information, paging configuration information, CORESET configuration information, Search space configuration information, and data scheduling information.

[0238] As another possible implementation form, 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. The second measurement result is a measurement result of the terminal measuring the first downlink measurement information transmitted from the network-side device. The first downlink measurement information is information transmitted 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 the first uplink measurement information transmitted from the terminal. The first uplink measurement information is information transmitted by the terminal to the network-side device when the amplifier is in the second state. The fourth measurement result is a measurement result of the terminal measuring the second downlink measurement information transmitted from the network-side device. The second downlink measurement information is information transmitted 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 the second uplink measurement information transmitted from the terminal. The second uplink measurement information is information transmitted by the terminal to the network-side device when the amplifier is in the first state.

[0239] As another possible implementation form, before the step of the network-side device transmitting the second information to the amplifier, the method further includes a step of the network-side device transmitting fifth indication information to the amplifier. The fifth indication information includes at least a switch for instructing the amplifier to switch to the first state or the second state command , and related time information for the amplifier to switch to the first state or the second state is carried.

[0240] As another possible implementation form, the related time information carries at least one of the transmission time information of the first downlink measurement information, the transmission time information of the first uplink measurement information, the transmission time information of the second downlink measurement information, and the transmission time information of the second uplink measurement information.

[0241] As can be understood, for the implementation process of each implementation form provided in this embodiment, reference can be made to the relevant descriptions in the above Method Embodiments 200-600, and the same technical effects can be obtained. To avoid repeated explanations, detailed descriptions are omitted here.
