Description

Technical Field

[0001] This application relates to the field of mobile communication technologies, and in particular, to a method and device for controlling the transmission state of an intermediate device. Background Art

[0002] The intermediate device of this application is based on a passive transmission device that controls the propagation of electromagnetic waves in a communication channel by means of reflection or transmission to improve the performance of the communication system. For example, an Intelligent Reflecting Surface (IRS) is based on the classical concept of a reconfigurable reflecting array. Specifically, an IRS is a metasurface composed of a large number of tiny elements that diffusely reflect incident signals in a controllable manner.

[0003] When a metasurface is applied in a communication system, the base station controls parameters such as the phase of the metasurface to better control the diffusely reflected incident signal and achieve controllable propagation of electromagnetic waves in the communication channel, so as to improve the performance of the communication system in terms of coverage, capacity, energy efficiency, etc. The metasurface can achieve controllable propagation with multiple phase changes. When deploying a metasurface in a wireless communication system, a suitable reflection coefficient needs to be designed to obtain the optimal performance gain. The calculation of the optimal reflection coefficient of the metasurface is related to the channel state information. Usually, the optimal reflection coefficient is configured after channel estimation. Therefore, the base station needs to first obtain the channel information from the base station to the metasurface and from the metasurface to the terminal, and then calculate the optimal reflection coefficient according to the channel state information, and then control the metasurface to adjust the phase of the base station's signal according to the optimal reflection coefficient to obtain the maximum gain of the system. If the metasurface can be equipped with a Radio Frequency (RF) chain, some or all of the metasurface elements are connected to the RF chain, and channel estimation can be performed at the base station. This involves three different operating modes of the metasurface device. One operating mode is that some elements of the metasurface are in the active state to receive data, another operating mode is that some elements of the metasurface are in the active state to send data, and the third operating mode is that the metasurface is in the passive transmission state, at which time the metasurface propagates the signal of the wireless electromagnetic wave in a controllable manner. Since the metasurface is a newly introduced entity in the communication system, signaling is required to indicate the operating mode of the metasurface device. Summary of the Invention

The wireless communication system includes a network device, an intermediate device, and a user equipment. The service signal generated by the network device is received by the user equipment after passing through the intermediate device. The method includes the following steps:

[0054] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0055] The following will describe in detail the technical solutions provided by each embodiment of the present application with reference to the accompanying drawings.

[0056] Figure 1 Schematic diagram of a multi - antenna wireless communication system enhanced for IRS.

[0057] The IRS is similar to the dish antenna used in satellite receivers. It is a passive device that reflects signals to improve the signal - to - noise ratio. Different phase - shift patterns of its different meta - surfaces cause incident signals to be reflected in different directions as beams of light. The IRS is a complement to traditional large - scale MIMO technology. Different from large - scale MIMO systems and cooperative relays, although the IRS also attempts to improve propagation conditions by deploying active hardware components, the IRS only requires very little operating power and thus is suitable for implementation in energy - limited systems. In addition, the IRS can naturally operate in full - duplex mode without the need for expensive self - interference cancellation. Moreover, the IRS is a very thin material and can be deployed on building facades and interior walls. Therefore, once a traditional network is deployed, one or more IRSs can be flexibly deployed to mitigate detected coverage holes or provide additional capacity in areas where needed.

[0058] Deploying intelligent metasurfaces in traditional MIMO systems is beneficial for two types of beamforming, such as Figure 1 shown. An IRS is deployed in a system to assist communication between a multi - antenna transmitter and a user. The information signal radiates from the transmitter. There may be a direct path for communication between the transmitter and the user. At the same time, the IRS also receives this information signal and reflects it. With the help of an infrared controller, the main direction of the reflected signal can be controlled. In particular, appropriate phase shifts are introduced on all meta - atoms to deliberately create a coherent combination of their respective scattered signals, thus generating a signal beam focused on the user. The larger the surface, the narrower the beam. This strategy is called energy focusing.

[0059] On the other hand, if there is no direct path due to severe shadowing or blockage, the transmitter should perform beamforming on the IRS. Then, the IRS can act as a non - amplified full - duplex relay, reflecting and focusing the signal to the terminal device UE to assist end - to - end communication. In Figure 1 , consider a scenario where a multi - antenna transmitter serves User 1 in the presence of User 2. Assume that the two UEs have different security levels, where the message of User 1 cannot be decoded by User 2. In this case, by adjusting the phase of the scattered signal to stop the signal at User 2, destructive reflection can be performed at the IRS. This strategy is called energy nulling.

[0060] Utilizing these two principles, it is expected that IRSs will have a wide range of applications in various communication systems, including interference management, coverage extension, and capacity improvement, such as wireless communication systems, cognitive radio networks, physical - layer security systems, etc.

[0061] It should be noted that the intermediate device of the present application controls the propagation of electromagnetic waves in the communication channel by means of reflection or transmission to improve the performance of the communication system, and is not limited to the use of IRS technology.

[0062] Figure 2 This is the method flow embodiment of the embodiment of the present application.

[0063] The embodiment of the present application proposes a method for indicating the transmission state signaling of a wireless communication system node. The wireless communication system includes a network device, an intermediate device, and a user device. The service signal generated by the network device is received by the user device after passing through the intermediate device. The method includes the following steps:

[0064] Step 101: Determine the indication information of the transmission state of the intermediate device and its occupied period, and the indication information is included in the downlink control signaling;

[0065] The transmission states include: a first state, a second state, and a third state that occur in sequence within each complete working cycle; the first state is the active reception state, the second state is the active transmission state, and the third state is the passive transmission state; the smallest granularity of the occupied period is a symbol;

[0066] Among them, the working periods of the first state and the second state include several time slots and / or symbols. Preferably, the period between at least one of the working periods of the first state and the second state includes no less than a set duration, such as a set number of symbols or time slots. The resource allocation is represented by the number of time slots and the number of symbols.

[0067] The downlink control signaling includes at least one of the following signaling: semi-static cell-specific control signaling, semi-static node-specific control signaling, and dynamic control signaling.

[0068] The cell-specific control signaling of the present application refers to the control signaling shared by the wireless communication devices in the cell;

[0069] The node-specific control signaling of the present application refers to the control signaling dedicated to the intermediate device.

[0070] Among them, the cell-specific status configuration information has the highest priority. Further, when the status information indicated by the semi-static signaling dedicated to the intermediate device conflicts with the dynamic control signaling, the dynamic control signaling has a higher priority.

[0071] Step 102: When the control signaling is semi-static cell-specific control signaling, the control signaling indicates: a first status time slot, a first status symbol, a second status time slot, a second status symbol, a first period, a second period, and a third period. The first period is the total period during which the control intermediate device is in the active receiving and active transmitting states. The second period is the period during which the intermediate device is in the third state (the passive transmission state). The third period is the total period during which the intermediate device operates, including the active state and the passive transmission state. That is, the time period of the second period is the time period of the third period minus the time period of the first period. The number of first status symbols is the number of symbols that are continuously in the first status starting from the starting symbol, and the number of second status symbols is the number of symbols that are continuously in the second status counting backward from the ending symbol.

[0072] Step 103: The control signaling is a combination of semi-static cell-specific control signaling and semi-static node-specific control signaling. The node-specific control signaling is a dedicated status configuration indication for the intermediate device, and the minimum indication granularity is at the symbol level. Among them, the node-specific signaling indicates the time slots that are further in the first state or the second state in the time slots not indicated by the cell-specific configuration, or further indicates the number of symbols in the first state after the start time of the time slots not indicated by the cell-specific configuration and the number of symbols in the second state before the end time.

[0073] Step 104: The control signaling is a combination of semi-static cell-specific control signaling, node-specific semi-static signaling, and dynamic control signaling. The dynamic control signaling is a dynamic status indication for the intermediate device, indicating the uplink and downlink symbol configurations of the time slots not indicated by the cell-specific configuration.

[0074] Step 105: The intermediate device receives pilot or data signals from the base station or the terminal in the first state, and sends channel state information, or pilot signals, or data signals to the base station or the terminal in the second state, where the transmission resources of the intermediate device and the transmission resources of the terminal are orthogonal.

[0075] For example, within the third period, after the network device sends the control signal of the first period, it sends the data of the passive transmission in the third state; the intermediate device completes the uplink and downlink pilot transceiver process in the first period and reflects / transmits the signal containing downlink service data in the second period.

[0076] The following details each downlink control signaling scheme in Steps 102 to 104.

[0077] The downlink control signaling first includes semi-static cell-specific control signaling, and further may include at least one of semi-static intermediate device node-specific control signaling and dynamic control signaling.

[0078] Solution 1: The downlink control signaling is semi-static cell-specific control signaling

[0079] Figure 3 Schematic diagram of the configuration duration for semi-static cell-specific control signaling. When the downlink control signaling includes semi-static cell-specific control signaling, one solution is that the cell-specific semi-static configuration information (state-configuration-common) in the semi-static cell-specific control signaling includes the following parameters: the first number of time slots S1, the second number of time slots S2, the first number of symbols C1, the second number of symbols C2, the first period T1, and also includes the second period T2 and / or the third period T3. During the first period, it includes the working durations when the intermediate device is in the first state and the second state; during the second period, it includes the working duration when the intermediate device is in the third state; the third period is the sum of the first period and the second period.

[0080] Further preferably, the "cell configuration first state duration" of the intermediate device includes S1 consecutive time slots at the start of the first period, and the "cell configuration second state duration" of the intermediate device includes S2 consecutive time slots before the end of the first period. Further, the cell configuration first state duration of the intermediate device also includes C1 consecutive symbols including the starting symbol in the next time slot at the end of the S1 time slots. Further, the cell configuration second state duration of the intermediate device also includes C2 consecutive symbols including the ending symbol in the previous time slot at the start of the S2 time slots.

[0081] The third period is the total working period of the intermediate device, including the active and passive transmission states. The durations of the first, second, and third periods are set with reference to the subcarrier spacing.

[0082] The number of time slots and the number of symbols represent resource allocation. For example, the number of time slots (S1) in the first state represents the number of consecutive "cell configuration first state time slots" at the start within the configured first period, and the number of common symbols (C1) in the first state represents the number of consecutive "cell configuration first state symbols" after the number of consecutive cell configuration first state time slots. The number of time slots (S2) in the second state represents the number of consecutive "cell configuration second state time slots" before the end within the configured first period, and the number of common symbols (C2) in the second state represents the number of consecutive "cell configuration second state symbols" before the number of consecutive cell configuration second state time slots. Alternatively, it further includes the number of time slots in the third state (S3). Between the last "cell configuration first state symbol" and the first "cell configuration second state symbol", there are consecutive unconfigured time slots or symbols, and the total length of the unconfigured time slots or symbols is greater than a set duration, which is used as the guard duration between uplink and downlink. Within the second or third period, after the network device sends the control signal of the first period, it sends the passively transmitted data in the third state. The time of the intermediate device in the third state is the second period, and the time period of the second period is the time period of the third period minus the time period of the first period.

[0083] Figure 4 Schematic diagram of another embodiment of the configuration duration for semi-static cell-specific control signaling. When the downlink control signaling includes semi-static cell-specific control signaling, another solution is that the semi-static cell-specific control signaling includes the following parameters: the first time slot index, the second time slot index, the first number of common symbols C1, the second number of common symbols C2, the first period T2, and further includes the second period T2 and / or the third period T3. Within the first period, it includes the working durations of the intermediate device in the first state and the second state. Within the second period, it includes the working duration of the intermediate device in the third state.

[0084] Further preferably, the cell configuration first state duration of the intermediate device includes all the time slots indicated by the first time slot index. The cell configuration second state duration of the intermediate device includes all the time slots indicated by the second time slot index. Further, the cell configuration first state duration of the intermediate device further includes C1 consecutive symbols including the starting symbol in the next unindexed time slot at the end moment of the time slot indicated by the first time slot index. Further, the cell configuration second state duration of the intermediate device further includes C2 consecutive symbols including the ending symbol in the previous unindexed time slot at the start moment of the time slot indicated by the second time slot index.

[0085] For example, the semi-static configuration signaling dedicated to the cell configures the first period, the second period, and / or the third period, and the subcarrier spacing, and indicates to the access point AP that the time slot index in the first period of the intermediate device corresponds to the first state or the second state; at this time, the cell-configured first state duration and the cell-configured second state duration may appear alternately. For example, the first state time slot Slot1 and the second state time slot Slot2 that first appear appear in sequence, and then the first state time slot Slot 3 appears; between the first state time slot and the second state time slot that first appear, the first state symbol and the second state symbol configuration may also be included; between the last symbol sybl 1 in the continuous cell-configured first state duration and the first symbol sybl 2 in the continuous cell-configured second state duration, continuous unconfigured time slots or symbols are included, and the total length of the unconfigured time slots or symbols is greater than a set duration, which is used as the protection duration between the uplink and the downlink. For the unindicated time slots, the number of symbols C1 indicating the transmission state of the previous time slot continued from the start symbol of the time slot where it is located, and the number of symbols C2 indicating the transmission state of the next time slot continued forward from the end symbol of the time slot where it is located are indicated.

[0086] Solution 2: The downlink control signaling is a combination of semi-static cell-specific control signaling and semi-static intermediate device node-specific control signaling

[0087] In any one of the embodiments of Solution 1, further, the downlink control signaling includes semi-static node-specific control signaling.

[0088] Figure 5 It is a schematic diagram of the configured duration of the semi-static node-specific control signaling. The semi-static cell-specific control signaling includes the following parameters: the first number of time slots S1, the second number of time slots S2, the first number of symbols C1, the second number of symbols C2, the first period T1, and also includes the second period and / or the third period. Within the first period, it includes the working durations of the intermediate device in the first state and the second state; within the second period, it includes the working duration of the intermediate device in the third state.

[0089] For example, the cell-configured first state duration of the intermediate device includes consecutive S1 time slots at the start of the first period, or may also include C1 consecutive symbols including the start symbol in the next time slot at the end of the S1 time slots. The cell-configured second state duration of the intermediate device includes consecutive S2 time slots before the end of the first period, or may also include C2 consecutive symbols including the end symbol in the previous time slot at the start of the S2 time slots.

[0090] The semi-static node-specific control signaling further configures the time slots or symbols of the first state and the second state during the period not configured by the semi-static cell-specific control signaling.

[0091] Preferably, the semi-static node-specific control signaling includes a first state-specific time slot index SN1 and a second state-specific time slot index SN2. The node of the intermediate device configures the first state duration, including all time slots indicated by the first state-specific time slot index during the period not configured by the semi-static cell-specific control signaling, as the time slots for the node to configure the first state; the node of the intermediate device configures the second state duration, including all time slots indicated by the second state-specific time slot index during the period not configured by the semi-static cell-specific control signaling, as the time slots for the node to configure the second state.

[0092] Preferably, the semi-static node-specific control signaling includes a first specific symbol number CN1 and a second specific symbol number CN2. The node of the intermediate device configures the first state duration, and further includes CN1 consecutive symbols including the start symbol after the end of any configured first state duration of the cell during the period not configured by the semi-static cell-specific control signaling, as the symbols for the node to configure the first state. The node of the intermediate device configures the second state duration, and further includes CN2 consecutive symbols including the end symbol before the start of any configured second state duration of the cell during the period not configured by the semi-static cell-specific control signaling, as the symbols for the node to configure the second state.

[0093] For example, the semi-static configuration status information specific to the cell is determined by the following parameters: the number of time slots in the first state and the number of common symbols in the first state, the number of time slots in the second state and the number of common symbols in the second state, the first period, the second period and / or the third period, and the subcarrier spacing. The node-specific control signaling indicates the specific state configuration for the intermediate device, and the minimum granularity of the indication is at the symbol level. Among them, the node-specific signaling indicates that the time slots in the area not indicated by the cell-specific configuration are in the first state or the second state, or indicates the number of symbols in the first state after the start of the time slots in the unindicated area or the number of symbols in the second state before the end of the time slots in the unindicated area.

[0094] At this time, the cell-configured second state duration and the node-configured second state duration are connected to each other; the cell-configured first state duration and the node-configured first state duration are connected to each other. Between the first state duration and the second state duration, there are consecutive unconfigured time slots or symbols, and the total length of the unconfigured time slots or symbols is greater than a set duration, which is used as the guard duration between the uplink and the downlink.

[0095] Figure 6 Schematic diagram of another embodiment of the configured duration for the semi-static node-specific control signaling.

[0096] When the downlink control signaling includes semi-static cell-specific control signaling, another solution is that the semi-static cell-specific control signaling includes the following parameters: a first time slot index, a second time slot index, a first number of common symbols C1, a second number of common symbols C2, a first period, and further includes a second period and / or a third period. Within the first period, it includes the working durations of the intermediate device in the first state and the second state; within the second period, it includes the working duration of the intermediate device in the third state.

[0097] For example, the cell of the intermediate device configures the first state duration, including all time slots indicated by the first time slot index and C1 consecutive symbols including the starting symbol in the next unindexed time slot at the end moment of the time slot indicated by the first time slot index. The cell of the intermediate device configures the second state duration, including all time slots indicated by the second time slot index, and C2 consecutive symbols including the ending symbol in the previous unindexed time slot at the start moment of the time slot indicated by the second time slot index.

[0098] The semi-static node-specific control signaling further configures the time slots or symbols of the first state and the second state during the period not configured by the semi-static cell-specific control signaling.

[0099] For example, the semi-static node-specific control signaling includes a first state-specific time slot index and a second state-specific time slot index. The node of the intermediate device configures the first state duration, including all time slots indicated by the first state-specific time slot index during the period not configured by the semi-static cell-specific control signaling; the node of the intermediate device configures the second state duration, including all time slots indicated by the second state-specific time slot index during the period not configured by the semi-static cell-specific control signaling.

[0100] For another example, the semi-static node-specific control signaling includes a first number of specific symbols CN1 and a second number of specific symbols CN2. The node of the intermediate device configures the first state duration, and further includes CN1 consecutive symbols including the starting symbol after the end of any period of the cell-configured first state duration during the period not configured by the semi-static cell-specific control signaling. The node of the intermediate device configures the second state duration, and further includes CN2 consecutive symbols including the ending symbol before the start of any period of the cell-configured second state duration during the period not configured by the semi-static cell-specific control signaling.

[0101] For example, the semi-static configuration signaling dedicated to the cell configures the first period, the second period, and / or the third period, and the subcarrier spacing. It indicates to the AP that the time slot index in the first period of the intermediate device corresponds to the first state. For the unindicated time slots, it indicates the number of symbols of the time slot starting from the start symbol and continuously preceding the first state time slot (e.g., Slot 1), or the number of symbols of the time slot starting from the end symbol and continuously following the first state time slot (e.g., Slot 2) forward. Furthermore, the node-specific control signaling indicates a dedicated state configuration for the intermediate device, and the minimum granularity of the indication is at the symbol level. The node-specific signaling indicates that some of the time slots in the area not indicated by the cell-specific configuration are in the first state or the second state (e.g., indicating that SN2 is in the second state), or the number of symbols of any time slot or symbol in the area not indicated by the cell-specific configuration that continues the state of the previous time slot or symbol, and the number of symbols of any time slot or symbol that continues the state of the next time slot or symbol. For example, the first-state symbols configured by the node are continuous in time with the first-state symbols configured by the cell (e.g., the first-state symbol C11 in the first stage configured by the cell and the first-state symbol CN11 in the first stage configured by the node are continuous; the first-state symbol C12 in the second stage configured by the cell and the first-state symbol CN12 in the second stage configured by the node are continuous); between two consecutive first-state durations, there is also a second-state time slot SN2 configured by the node. Between the consecutive first-state duration and the second-state duration, there are continuous unconfigured time slots or symbols, and the total length of the unconfigured time slots or symbols is greater than a set duration, which is used as the guard duration between the uplink and the downlink.

[0102] In any of the above embodiments, further, the downlink control signaling includes dynamic control signaling, such as Solution 3 to Solution 4:

[0103] Solution 3: The downlink control signaling is semi-static cell-specific control signaling combined with intermediate device node dynamic control signaling;

[0104] For example, the semi-static configuration signaling dedicated to the cell configures the first period, the second period, and the subcarrier spacing. The semi-static configuration state information dedicated to the cell also includes: the number of first-state time slots, the number of first-state common symbols, the number of second-state time slots, the number of second-state common symbols, or,, it indicates to the AP that the time slot index in the first period of the intermediate device corresponds to the first transmission state or the second transmission state. For the unindicated time slots, it indicates the number of symbols of the time slot starting from the start symbol and continuing the transmission state of the previous time slot, and the number of symbols of the time slot starting from the end symbol and continuing the transmission state of the next time slot forward.

[0105] The node dynamic control signaling is a status indication of the intermediate device dynamics, indicating the uplink and downlink symbol configuration of the time slots in the area not indicated by the cell-specific configuration. The dynamic control signaling of the intermediate device is scrambled by the RNTI of the newly defined intermediate device time slot format, indicating the information of the first state and the second state of several specified time slots of the intermediate device.

[0106] The dynamic control signaling further configures the time slots or symbols in the first state and the second state during the period when the semi-static cell-specific control signaling is not configured.

[0107] Preferably, the dynamic control signaling includes the first dedicated symbol number CN1 and the second dedicated symbol number CN2. The node of the intermediate device configures the duration of the first state, including CN1 consecutive symbols including the start symbol after any period of "cell-configured first state duration" ends during the period when the semi-static cell-specific control signaling is not configured. The node of the intermediate device configures the duration of the second state, including CN2 consecutive symbols including the end symbol before the start of any period of "cell-configured second state duration" during the period when the semi-static cell-specific control signaling is not configured.

[0108] Preferably, the dynamic control signaling is scrambled by the RNTI of the intermediate device and includes the information indicating the state of any time slot in the first period, including at least one of the following states of the any time slot: all symbols are in the first state, all symbols are in the second state, some symbols are in the first state, and some symbols are in the second state.

[0109] Solution 4: The downlink control signaling is a semi-static cell-specific control signaling, combined with the semi-static intermediate device node-specific control signaling and the dynamic control signaling.

[0110] For example, the cell-specific semi-static configuration signaling configures the first period, the second period, and the subcarrier spacing. Its cell-specific semi-static configuration status information further includes: the number of time slots in the first state, the number of common symbols in the first state, the number of time slots in the second state, the number of common symbols in the second state. Or, it indicates the first transmission state or the second transmission state corresponding to the time slot index in the first period of the AP indicating the intermediate device. For the unindicated time slots, it indicates the number of symbols continuing the transmission state of the previous time slot starting from the start symbol of the time slot, and the number of symbols continuing the transmission state of the next time slot forward from the end symbol of the time slot.

[0111] For the areas that remain unindicated after the cell-specific indication, the semi-static node-specific control signaling is the dedicated status configuration indicated to the intermediate device, and the minimum indication granularity is at the symbol level. Among them, the signaling indication dedicated to the intermediate device indicates that several time slots in the area not indicated by the cell-specific configuration are in the first state or the second state, or the number of consecutive symbols in the first state after the start time of any time slot in the unindicated area, or the number of consecutive symbols in the second state before the end time of the time slot in the unindicated area.

[0112] For the areas that remain unindicated after the cell-specific indication, the node dynamic control signaling is the dynamic status indication for the intermediate device, indicating the uplink and downlink symbol configuration of the time slots in the area not indicated by the cell-specific configuration. The dynamic control signaling is scrambled by the RNTI (internode-RNTI) of the newly defined intermediate device time slot format, and the information on the first state and the second state of a single time slot is indicated to the intermediate device.

[0113] Among them, the cell-specific status configuration information has the highest priority. Secondly, when indicating the area not indicated by the cell-specific configuration information, the priority of the dynamic control signaling is higher than that of the semi-static node-specific control signaling. That is to say, when the node configures the duration of the first state, if the dynamic control signaling indicates that any time slot or symbol is in the second state, then the any time slot or symbol is set to the second state; when the node configures the duration of the second state, if the dynamic control signaling indicates that any time slot or symbol is in the first state, then the any time slot or symbol is set to the first state.

[0114] Figure 7 It is a schematic diagram of the signaling indication and response process of the method of the present invention.

[0115] Step 201: The base station or AP uses semi-static or dynamic control signaling to configure the intermediate device to be in the transmission state or the reception state at the symbol level in the first period T1, configures the third period T3 as the total transmission period of the intermediate device, and configures the second period T2 = T3 - T1 as the passive transmission state of the intermediate device. The network device includes the following steps: Step 201A: Transmit the downlink control signaling; for the intermediate device, it includes the following steps: Step 201B: Receive the downlink control signaling.

[0116] Step 202: During the time period of the first cycle T1, in the time slots or symbols when the intermediate device is in the first state, the intermediate device is in the listening state. One example is that the base station or AP sends downlink pilot signals to M users accessing the base station or AP in the downlink subframe, and the M terminals (i.e., user devices) accessing the AP send uplink pilot signals to the AP in the uplink subframe, and the intermediate device receives the uplink and downlink pilot signals. The network device includes the following steps: Step 202A: During the time period occupied by the first state, send downlink pilot signals. The intermediate device includes the following steps: Step 202B: During the time period occupied by the first state, receive the downlink pilot signals from the network device and / or receive the uplink pilot signals from the user device. The user device includes the following steps: Step 202C: During the time period occupied by the first state, send uplink pilot signals.

[0117] Step 203: During the time period of the first cycle T1, in the time slots or symbols when the intermediate device is in the second state, the intermediate device is in the transmitting state. One example is that the channel estimation information of the intermediate device (including the channel state information from the base station to the intermediate device and from the intermediate device to the terminal) is sent to the network device. For example, the intermediate device sends the uplink pilot signals to the base station, and at this time, the uplink resources of the intermediate device and the M terminals are orthogonal in time, frequency, space, or sequence. The network device includes the following steps: Step 203A: During the time period occupied by the second state, receive the channel state feedback information from the intermediate device or the uplink pilot signals from the intermediate device. The intermediate device includes the following steps: Step 203B: During the time period occupied by the second state, obtain the channel state information between the network device and the intermediate device and between the intermediate device and the user device, and send the channel state information to the network device; or, the intermediate device sends the uplink pilot signals during the time period of the second state.

[0118] Step 204: The base station or AP is in the third state during the time period of the second cycle T3 - T1. One example is that the base station or AP calculates the information Θ for controlling the phase, amplitude, etc. of the intermediate device using the channel state feedback information received from the intermediate node during the time period of the first cycle T1. At the time period of T3, the base station or AP sends downlink data to the terminal, or the terminal sends uplink data to the AP, and the data is adjusted by the control information Θ of the intermediate device. The network device includes the following steps: Step 204A: Calculate and send control information according to the channel state information fed back by the intermediate device, where the control information is used to adjust the phase and amplitude characteristics of the third state of the intermediate device; during the time period occupied by the third state, send downlink service data or receive uplink service data. The intermediate device includes the following steps: Step 204B: Passively transmit the downlink service data from the network device or the uplink service data from the user equipment during the time period occupied by the third state. The user equipment includes the following steps: Step 204C: Receive downlink service data or send uplink service data during the time period occupied by the third state.
