[0016] FIG. 1 shows a block diagram of a wireless communication system to which the embodiment of the present application can be applied. The wireless communication system includes a terminal 11 and a network side device 12. Here, the terminal 11 may be called a terminal device or a user terminal (User Equipment), and the terminal 11 may be a terminal side device such as a mobile phone, a tablet personal computer, a laptop computer (or called a notebook computer), a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device, a vehicle user equipment (VUE), a pedestrian user equipment (PUE), etc., and the wearable device includes a bracelet, an earphone, glasses, etc. It should be noted that the specific type of the terminal 11 in the embodiment of the present application is not limited.

[0017] In addition, the relevant terms in this application will be interpreted accordingly. 1. Intelligent Surfaces / Super Material Surfaces Intelligent Surfaces is an emerging technology and there are multiple related terms, all of which describe similar technologies or entities, including Large Intelligent Surface (LIS), Smart Reflect Array (SRA), Reconfigurable Reflect Array (RRA), and Intelligent Reflecting Surface (IRS).

[0018] As shown in Figure 2, the intelligent surface equipment is composed of a large-scale device array and an array control module. A large-scale device array is a large number of device units arranged regularly and repeatedly on a flat base plate. In order to achieve a significant signal control effect, a device array generally needs to be composed of hundreds or thousands of device units. Each device unit has a variable device structure, for example, a device unit includes a PIN diode, and the response mode of the device unit to the external wireless signal is determined by the switch state of the PIN diode. The array control module of the intelligent surface can dynamically or semi-statically control the response mode of each device unit to the wireless signal by controlling the working state of each device unit. The wireless response signals of each device unit in the large-scale device array are superimposed on each other to form a certain beam propagation characteristic in a macroscopic view. The control module is the "brain" of the intelligent surface equipment, and determines the wireless signal response beam of the intelligent surface according to the demand of the communication system, making the original static communication environment "intelligent" and "controllable".

[0019] Intelligent surface technology is applied in multiple technical fields, and there are various different design proposals for different application scenarios. According to the physical principle of the device unit [3], it includes Tunable Resonator variable capacitance type, Guided Wave type, Element Rotation polarization type, etc. According to the wireless signal output format, it can be divided into reflective intelligent surface and transparent intelligent surface. According to the wireless signal response parameters [4], it includes phase control type intelligent surface, amplitude control type intelligent surface and amplitude phase coordinated control type intelligent surface. According to the response parameter control, it can be divided into continuous control type and discrete control type. According to the frequency or speed of controlling the amplitude and phase of the intelligent surface, it can be divided into static, semi-static / dynamic control intelligent surface, where static intelligent surface can be applied to all systems, such as 4G / 5G systems. Considering the complexity of device design and fabrication, academic circles generally choose discrete control type device units using a single wireless signal response parameter for research. Currently, Intelligent Reflecting Surfaces (IRS), which are being widely studied in the academic community, are phase-controlled intelligent surfaces that use signal reflection to control the phase of the reflected signal from the device unit using 1-bit instruction information, achieving phase inversion of 0 or π.

[0020] By not requiring radio frequency and baseband processing circuits, intelligent surface devices can: 1) The cost and implementation complexity of intelligent surface equipment is lower; 2) Intelligent surface devices consume less power; 3) the intelligent surface does not introduce extra receiving-end thermal noise; 4) Intelligent surface equipment has several advantages, such as thin thickness, small weight and flexible deployment.

[0021] Here, there are the following types of IRS reflector units:

[0022] A. Tunable resonator: A variable capacitor is integrated into the resonator to generate a phase shift by changing the frequency of the frequency-agile patch resonator.

[0023] B. Guided Wave Control Method: In this case, the arriving spatial wave is coupled by an antenna into a guided wave, which is then phase shifted and relaunched, forming an antenna phase shifter.

[0024] C. Circularly polarized wave rotation technology: Designed using the laws of electromagnetic wave reflection.

[0025] From the perspective of whether they can be dynamically controlled or not, reflectarrays / intelligent surfaces are classified into two categories:

[0026] 1) Static reflectarray / intelligent surface: The structure and function of the reflectarray can be fixed. For an incident wave from one angle, the metasurface unit will change the amplitude, phase, polarization mode and other characteristics of the incident wave in a fixed manner to obtain a corresponding reflected wave.

[0027] 2) Dynamic reflectarray / intelligent surface: The structure and function of the reflectarray are controllable, and for an incident wave from one angle, different changes can be generated in the amplitude, phase, polarization mode and other characteristics of the incident wave through programmable control, and a corresponding reflected wave can be obtained. To realize programmable control over the reflect metasurface, it is necessary to introduce a switching element (e.g., diode, RF-MEMS switch, etc.) into the reflector. PIN diodes are currently a common choice for controlling reconfigurable metasurfaces, and PIN diodes have a wide range of radio frequency impedance and low distortion, and are widely used in the field of microwave radio frequency. The switching element in the reflector allows the reflector to have multiple different states, and by controlling the on-off of the switching element, the switching of different states can be realized. When the switching element is on or off, the structure and performance of the corresponding reflector will both change significantly. That is, the reflector units in different states have different adjustment control modes for the amplitude, phase, polarization and other characteristics of the incident wave.

[0028] II. Direct signal modulation by intelligent surfaces Since the intelligent surface can directly adjust and control the wavefront and various electromagnetic parameters of the electromagnetic signal, such as phase, amplitude, frequency, and even polarization, without requiring complex baseband processing and radio frequency transmission and reception operations, the intelligent surface can not only improve the reception quality of third-party signals by changing the wireless channel environment, but can also be used for direct modulation of signals.

[0029] For example, adjusting the reflection phase / amplitude of the electromagnetic unit of the intelligent surface can be used not only to maximize the signal-to-noise ratio of the reception of the incident electromagnetic wave, but also to transmit information of the LIS itself. The receiving end receives the information of the intelligent surface itself by detecting the phase / amplitude change of the reflection signal of the intelligent surface.

[0030] 3. Passive intelligent surfaces Because the intelligent surface is composed of a large number of device units and does not have radio frequency and baseband processing capabilities, such an intelligent surface is called a passive intelligent surface.

[0031] 4. Active-passive combined intelligent surfaces (or active intelligent surfaces) Because the intelligent surface is composed of a large number of device units and lacks radio frequency and baseband processing capabilities, the base station cannot obtain channel information from the base station to the intelligent surface and from the intelligent surface to the terminal, respectively. The received signal of the base station or the terminal is formed by the superposition of the response signals of a large number of intelligent surface device units, and changing the working state of one or a small number of device units cannot cause obvious changes in the received signal. As a possible measurement method, a small number of active device units are installed on the intelligent surface, so that the intelligent surface can perform channel measurement and feedback, and the base station uses compressed sensing or deep learning algorithms to estimate reasonable intelligent surface configuration parameters from limited channel information. The communication system based on the intelligent surface requires an efficient channel measurement mechanism, and on the premise of ensuring that the complexity of the intelligent surface is low, it is necessary to improve the end-to-end signal quality as much as possible. Some intelligent surfaces equipped with such active devices have the ability to receive signals and then transmit signals, and are active-passive combined intelligent surfaces (or active intelligent surfaces).

[0032] Conventional relay devices include layer 1 relays, layer 3 relays, amplify-and-forward relays, transparent-and-forward relays, etc. LIS can be regarded as a new type of relay.

[0033] Hereinafter, the working state switching method according to the embodiment of the present application will be described in detail with reference to specific embodiments and application scenarios in conjunction with the drawings.

[0034] An embodiment of the present application provides a method for switching working states. FIG. 3 is a flow chart of the method for switching working states in the embodiment of the present application. As shown in FIG. 3, the steps of the method include: Step S302, when the trigger condition is satisfied, the terminal switches from operating in the first operating state to operating in the second operating state; and a step S304 in which the terminal performs a receiving operation in a second working state; Here, the first operating state is that the terminal is in a first state in a first downlink, and the second operating state is that the terminal is in a second state in a second downlink; The first downlink or the second downlink includes at least one of downlink A, downlink B, and downlink C, where downlink A is a link through which a network side device transmits information to a terminal, downlink B is a link through which a large intelligent surface LIS or a relay device transmits information to the terminal by changing a signal characteristic of downlink A, and downlink C is a link through which the LIS or the relay device transmits information directly to the terminal; The trigger condition is 1) receiving target signaling instructing the terminal to switch from a first operating state to a second operating state; and 2) the target timer of the first active state has timed out.

[0035] According to the above steps S302 and S304, the terminal can switch from the first working state to the second working state when the trigger condition is satisfied, and the downlink in the first working state and the second working state can be a link where the network side device transmits information to the terminal, or a link where the large intelligent surface LIS or relay device transmits information to the terminal by changing the signal characteristics of the downlink A, or a link where the LIS or relay device transmits information directly to the terminal. For example, if the reception of the downlinks B and C is easier than that of the downlink A, when there is no data transmission or when the data transmission is low-speed, the terminal only needs to receive the signals / data of the downlinks B and C and a small amount of measurement of the downlink A, thereby saving the power consumption of the terminal without affecting the transmission efficiency. Of course, this is only an exemplary description of one possible embodiment of the embodiment of the present application, that is, according to the present application, in a system consisting of a LIS and a base station, the terminal can operate on different downlink logical links and switch between different downlink logical links as necessary, thereby achieving the effect of achieving both transmission efficiency and terminal power saving.

[0036] Optionally, the first state or the second state in the embodiment of the present application includes at least one of an RRC idle state, a deactivated state, and a connected state. Based on this, the first working state or the second working state in the embodiment of the present application may be, in a specific application scenario, an idle state or a deactivated state in downlink A, a connected state in downlink B, an idle state or a deactivated state in downlink C, and a connected state in downlink C. Of course, the above first working state or the second working state is a preferred working state in the embodiment of the present application, and in other application scenarios, the first working state or the second working state may further be a connected state in downlink A, an idle state or a deactivated state in downlink B, etc.

[0037] It should be clarified that the LIS in the embodiments of the present application may be an active LIS or a passive LIS, and the relay device may be an active relay device or a passive relay device.

[0038] The present application will be described below in conjunction with the type of LIS or relay device and the specific situation between the first working state and the second working state.

[0039] Method 1-1: LIS is a passive LIS and or Relay device If the terminal is a passive relay device and the first working state is that the terminal is in an idle state or a deactivated state in the downlink A, step S30 of the embodiment of the present application 2 The switching of the terminal from operating in a first operating state to operating in a second operating state includes: Step S30 in which the terminal monitors a first signaling on the downlink A. 2 -11, A step S30 in which the terminal switches from operating in a first operating state to operating in a second operating state based on the first signaling. 2 -12, where the second operating state is that the terminal is on downlink B and in a connected state, or the second operating state is that the terminal is on downlink A and in a connected state.

[0040] It should be noted that for a passive LIS or relay, a large system consisting of an intelligent surface or relay and a base station has two downlinks and one uplink, as shown in Figure 4. In downlink A, the base station transmits base station information (including the influence of the LIS or relay device on the wireless channel between the base station and the terminal) to the terminal, and downlink A is a wireless logical link through which the base station communicates with the terminal, and its corresponding physical link is through which the base station transmits a first type of downlink signal to the terminal, and the first type of downlink signal includes control information and data information.

[0041] In the downlink B, the LIS or relay device transmits information of the LIS or relay device itself to the terminal by changing the signal characteristics of the downlink A, such as phase, amplitude, etc., and the downlink B is a wireless logical link through which the LIS or relay device communicates with the terminal. For a passive LIS or relay device, the physical link of the downlink B is one in which the intelligent surface or relay device carries information of the intelligent surface or relay device by modulating parameters (including at least one of phase, amplitude, polarization direction, etc.) of the second type of downlink signal transmitted from the base station. The second type of downlink signal may be a downlink signal such as a Physical Downlink Control Channel (PDCCH) or a Physical Downlink Shared Channel (PDSCH) transmitted from the base station, or a signal transmitted in an idle state that does not carry data, such as a single-frequency signal, and the information of the intelligent surface or relay device may be information generated by the intelligent surface or relay device itself or information from the base station (such as simple control information or small data, etc.).

[0042] When the second operating state is that the terminal is on downlink B and in a connected state, the configuration information of the second operating state is notified by a system message or a first signaling, where the system message is a system message of the first operating state.

[0043] According to this method 1-1, in a specific application scenario, the first operating state is that the terminal is in an idle / inactive state in downlink A. In this first operating state, the terminal: Step S11: the terminal periodically measures a synchronization signal / reference signal of downlink A; The terminal may perform method steps with step S12 of monitoring a first signaling, e.g., paging, on downlink A, where the first signaling indicates whether the terminal needs to enter a second operating state, where the second operating state is that the terminal is on downlink B and in a connected state, or where the second operating state is that the terminal is on downlink A and in a connected state.

[0044] It should be noted that the transmission configuration information of the second operating state is notified to the terminal by a system message of the first operating state or a first signaling, such as paging, where the configuration information includes time-domain / frequency-domain information in which the terminal receives downlink information in the second operating state, related information of a Modulation and Coding Scheme (MCS), and relationships between changes in signal features such as phase / amplitude and information represented thereby, etc.

[0045] Method 1-2: When the LIS is a passive LIS or a passive relay device, and the first working state is that the terminal is on the downlink B and in a connected state, step S30 of the embodiment of the present application 2 The method for switching the terminal from operating in the first operating state to operating in the second operating state is as follows: Step S30 in which the terminal monitors a second signaling on the downlink B. 2 -21, A step S30 in which the terminal switches from operating in the first operating state to operating in the second operating state based on the second signaling. 2 -22, where the second operating state is that the terminal is on downlink A and in an idle state or a deactivated state, or the second operating state is that the terminal is on downlink A and in a connected state.

[0046] It should be noted that the data transmission in the first working state is realized by changing the phase, amplitude or frequency of the dedicated signal of downlink A, or by changing the phase, amplitude or frequency of the non-dedicated signal of downlink A.

[0047] In addition, the first operating state is that the terminal is on downlink B and in a connected state, and the first operating state may be an operating state that the terminal enters during low-speed data transmission. Based on this, for this method 1-2, in a specific application scenario, the terminal enters the second operating state (the terminal is on downlink A and in an idle state or a deactivated state) based on a first signaling indication of the second operating state (the terminal is on downlink A and in a connected state) or the second signaling indication of the second operating state (the terminal is on downlink A and in a connected state). two This first operating state may be entered based on a signaling indication from the .

[0048] In the first operating state of this method 1-2, the uplink transmission is A link in which a terminal indirectly transmits information to a LIS or a relay device, and a network side device receives information transmitted from the terminal and transfers it to the LIS or the relay device (the uplink is a wireless logical link from the terminal to the LIS or the relay device); This is done via at least one of two types of uplinks, the link through which the terminal transmits information directly to the network side device.

[0049] It should be noted that the data transmission in the first working state in this mode 1-2 may be realized by changing the characteristic phase / amplitude, etc. of the dedicated signal of downlink A, or by changing the characteristic phase / amplitude, etc. of the always-on signal of downlink A, such as a synchronization signal and PBCH block (SSB), SIB1, a Channel-State Information Reference Signal (CSI-RS) / Tracking Reference Signal (TRS) in an idle state.

[0050] In addition, the mobility management in this first operating state is for the terminal to periodically measure the synchronization signal / reference signal of downlink A.

[0051] Optionally, the terminal monitors a first signaling, such as paging, on downlink A, where the first signaling indicates to the terminal whether or not it needs to enter a second operating state.

[0052] In addition, according to this method 1-2, when the LIS is a passive LIS or a passive relay device, and the first operating state is that the terminal is on the downlink B and in a connected state, the method for the terminal to switch from the first operating state to the second operating state in the embodiment of the present application is as follows: a step S30 in which the terminal switches from operating in the first operating state to operating in the second operating state when a first timer in the first operating state times out; 2 -31, where the second operating state is that the terminal is on downlink A and in an idle state or a deactivated state, or the second operating state is that the terminal is on downlink A and in a connected state. When the terminal receives a scheduling signaling in the first operating state, for example a scheduling signaling indicating a new packet, the terminal starts or restarts the first timer.

[0053] Method 1-3: When the LIS is a passive LIS or a passive relay device, and the first working state is that the terminal is on the downlink A and in a connected state, step S30 in the embodiment of the present application 2 The method for switching the terminal from operating in the first operating state to operating in the second operating state is as follows: Step S30 in which the terminal monitors a third signaling on the downlink A. 2 -41, A step S30 in which the terminal switches from operating in the first operating state to operating in the second operating state based on the third signaling. 2 -42, where the second operating state is that the terminal is on downlink A and in an idle state or a deactivated state, or the second operating state is that the terminal is on downlink B and in a connected state.

[0054] According to this method 1-3, when the LIS is a passive LIS or a passive relay device, and the first working state is that the terminal is on the downlink A and in a connected state, step S30 in the embodiment of the present application 2 The method for switching the terminal from operating in the first operating state to operating in the second operating state is as follows: a step S30 in which the terminal switches from operating in the first operating state to operating in the second operating state when a second timer in the first operating state times out; 2 -51, where the second operating state is that the terminal is on downlink A and in an idle state or a deactivated state, or the second operating state is that the terminal is on downlink B and in a connected state. When the terminal receives a scheduling signaling in the first operating state, for example a scheduling signaling indicating a new packet, the terminal starts or restarts the second timer.

[0055] It should be noted that the first working state is that the terminal is on downlink A and in a connected state, and the first working state may be an working state that the terminal enters during high-speed data transmission. Based on this, for the method 1-3, in a specific application scenario, the terminal enters the second working state (the terminal is on downlink A and in an idle state or a deactivated state) based on a first signaling indication, or the second working state (the terminal is on downlink B and in a connected state) based on a first signaling indication. three Based on a signaling instruction from the first operating state, the first operating state is entered.

[0056] Optionally, the uplink transmission in the first operating state comprises: A link in which a terminal indirectly transmits information to an LIS or a relay device, and a network side device receives the information transmitted from the terminal and transfers it to the LIS or the relay device; This is done via at least one of two types of uplinks, the link through which the terminal transmits information directly to the network side device.

[0057] The transmission configuration information of the second operating state in this method 1-3 may be notified to the terminal by signaling of the first operating state, for example, RRC signaling, and the configuration information includes time-domain / frequency-domain information, MCS-related information, and relationships between changes in signal features such as phase / amplitude and information represented thereby when the terminal receives downlink information in the second operating state.

[0058] In the first operating state of this mode 1-3, the mobility management may be that the terminal periodically measures the downlink A synchronization signal / reference signal.

[0059] Optionally, the terminal monitors a first signaling, such as paging, on downlink A, where the paging indicates to the terminal whether or not it needs to enter the second operating state.

[0060] The above methods 1-1 to 1-3 are interpretations of the present application from the viewpoint of a passive LIS or a passive repeater device, and in the following, the present application will be interpreted from the viewpoint of an active LIS or an active repeater device.

[0061] Method 2-1: When the LIS is an active LIS or the relay device is an active relay device, and the first working state is that the terminal is in an idle state or a deactivated state in the downlink A, step S30 2 The method for switching the terminal from operating in the first operating state to operating in the second operating state is as follows: Step S30 in which the terminal monitors a fourth signaling on the downlink A. 2 -61, A step S30 in which the terminal switches from operating in the first operating state to operating in the second operating state based on the fourth signaling. 2 -62, where the second operating state is that the terminal is on downlink C or downlink A and in a connected state, or the second operating state is that the terminal is on downlink A and in a connected state.

[0062] It should be explained that when the second operating state is that the terminal is on downlink C or downlink A and in a connected state, the configuration information of the second operating state is notified by a system message or a first signaling, where the system message is a system message of the first operating state.

[0063] For this method 2-1, in a specific application scenario, the terminal periodically measures the synchronization signal / reference signal of downlink A, and the terminal may monitor a first signaling, such as paging, on downlink A, where the first signaling indicates to the terminal whether it needs to enter the second operating state.

[0064] Here, the transmission configuration information of the second operating state is notified to the terminal by a system message of the first state or a first signaling, for example, paging, and the configuration information includes at least one of time domain / frequency domain information in which the terminal receives uplink and / or downlink in the second operating state, uplink / downlink MCS related information, TRP ID information (or LIS ID, etc.) related to downlink C, synchronization information (channel raster, sync raster, number of SSBs, etc.), Quasi Co-Location (QCL) information relationship (for example, QCL relationship between SSB / CSI-RS / TRS in the second operating state and SSB / CSI-RS / TRS in the first operating state), beam information, etc.

[0065] It should be noted that the uplink transmission in the first working state is 1) A link through which a terminal transmits information directly to a LIS or relay device that includes an active receiving module or an active transmitting / receiving module; 2) A link in which a terminal indirectly transmits information to a LIS or a relay device, and a network side device receives information transmitted from the terminal and transfers it to the LIS or the relay device (the uplink is a wireless logical link from the terminal to the LIS or the relay device, and an intelligent surface in which a small number of active transmission and reception modules are integrated can receive the uplink signal of the terminal); 3) A link where the terminal transmits information directly to the network side device; 4) A link through which a terminal indirectly transmits information to a network side device, and the LIS or relay device receives the information transmitted from the terminal and forwards it to the network side device (the uplink is a logical link from the intelligent surface to the network side device, and the LIS or relay device passes the received terminal information to the network side device, and the actual physical channel between the LIS or relay device and the network side device may be a wireless link or a wired link), via at least one of four types of uplinks (for example, the uplink initiates a random access process when a task needs to be transmitted).

[0066] In the method 2-2, when the LIS is an active LIS or the relay device is an active relay device, and the first working state is that the terminal is on the downlink C or the downlink A and in a connected state, step S30 in the embodiment of the present application 2 The method for switching the terminal from operating in the first operating state to operating in the second operating state is as follows: Step S30 in which the terminal monitors a fifth signaling on the downlink A. 2 -71, A step S30 in which the terminal switches from operating in the first operating state to operating in the second operating state based on the fifth signaling. 2 -72, where the second operating state is that the terminal is in an idle state or a deactivated state in downlink A, or the second operating state is that the terminal is on downlink A and in a connected state.

[0067] It should be noted that, when the LIS is an active LIS or the relay device is an active relay device, and the first working state is that the terminal is on the downlink C or the downlink A and in a connected state, step S30 in the embodiment of the present application 2 The method for switching the terminal from operating in the first operating state to operating in the second operating state is as follows: a step S30 in which the terminal switches from operating in the first operating state to operating in the second operating state when a third timer in the first operating state times out; 2 -81, where the second operating state is that the terminal is in an idle state or a deactivated state in downlink A, or the second operating state is that the terminal is on downlink A and in a connected state. When the terminal receives a scheduling signaling in the first operating state, for example a scheduling signaling indicating a new packet, the terminal starts or restarts a third timer.

[0068] The first operating state (connected state of downlink C) in this method 2-2 is generally an operating state that a terminal enters during low-speed data transmission, and in a specific application scenario, the terminal enters this first operating state based on a first signaling indication of the second operating state (the terminal is in an idle state or a deactivated state in downlink A) or based on a third signaling indication of the second operating state (the terminal is on downlink A and in a connected state).

[0069] Here, when entering the first operating state based on the third signaling indication, the terminal may determine the beam / SSB / CSI-RS information of the first operating state (the terminal is on downlink C or downlink A and in a connected state) to be preferentially measured based on the beam / SSB / CSI-RS information of the second operating state (the terminal is on downlink A and in a connected state) and the first mapping table, where the first mapping table defines a mapping relationship, such as a QCL relationship, between the beam / SSB / CSI-RS of the first operating state and the beam / SSB / CSI-RS information of the second operating state (the terminal is on downlink A and in a connected state). Because the mapping relationship between different operating states is defined by the first mapping table, the terminal can more quickly perform downlink measurement and synchronization and more quickly realize state switching.

[0070] Here, when entering the first operating state based on the first signaling indication, the terminal may determine the beam / SSB / CSI-RS information of the first operating state (the terminal is on downlink C or downlink A and in a connected state) to be preferentially measured based on the beam / SSB / CSI-RS information of the second operating state (the terminal is in an idle state or a deactivated state in downlink A) and the second mapping table. Here, the second mapping table defines a mapping relationship, such as a QCL relationship, between the beam / SSB / CSI-RS of the second operating state (the terminal is in an idle state or a deactivated state in downlink A) and the beam / SSB / CSI-RS information of the first operating state (the terminal is on downlink C or downlink A and in a connected state). Because the mapping relationship between different operating states is defined by the second mapping table, the terminal can more quickly perform downlink measurement and synchronization and more quickly realize state switching.

[0071] In the first operating state of method 2-2, the uplink transmission is 1) A link through which a terminal transmits information directly to a LIS or relay device that includes an active receiving module or an active transmitting / receiving module; 2) A link in which a terminal indirectly transmits information to a LIS or a relay device, and a network side device receives information transmitted from the terminal and transfers it to the LIS or the relay device (the uplink is a wireless logical link from the terminal to the LIS or the relay device, and an intelligent surface in which a small number of active transmission and reception modules are integrated can receive the uplink signal of the terminal); 3) A link where the terminal transmits information directly to the network side device; 4) A link through which a terminal indirectly transmits information to a network side device, and the LIS or relay device receives the information transmitted from the terminal and forwards it to the network side device (the uplink is a logical link from the intelligent surface to the network side device, and the LIS or relay device passes the received terminal information to the network side device, and the actual physical channel between the LIS or relay device and the network side device may be a wireless link or a wired link). This is performed via at least one of four types of uplinks.

[0072] In the first working state in method 2-2, data transmission in the uplink and downlink is performed by active devices of the terminal and the LIS.

[0073] In the first operating state in mode 2-2, the mobility management may be that the terminal periodically measures the synchronization signal / reference signal of downlink A, or that the terminal periodically measures the synchronization signal / reference signal of downlink B.

[0074] Optionally, the terminal monitors a first signaling, such as paging, on downlink A, where the first signaling indicates to the terminal whether or not it needs to enter a second operating state.

[0075] In the manner 2-3, when the LIS is an active LIS or the relay device is an active relay device, and the first working state is that the terminal is on the downlink A and in a connected state, step S30 of the embodiment of the present application 2 The method for switching the terminal from operating in a first operating state to operating in a second operating state is as follows: Step S30 in which the terminal monitors a sixth signaling on the downlink A. 2 -91, A step S30 in which the terminal switches from operating in the first operating state to operating in the second operating state based on the sixth signaling. 2-92, where the second operating state is that the terminal is in an idle state or a deactivated state on downlink A, or the second operating state is that the terminal is on downlink C or downlink A and in a connected state.

[0076] According to this method 2-3, step S30 of the embodiment of the present application 2 may further include the terminal switching from operating in the first operating state to operating in a second operating state when a fourth timer in the first operating state times out, where the second operating state is that the terminal is in an idle state or a deactivated state in downlink A, or the second operating state is that the terminal is on downlink C or downlink A and in a connected state. The terminal starts or restarts the fourth timer when it receives scheduling signaling in the first operating state, for example scheduling signaling indicating a new packet.

[0077] Optionally, the method in the embodiments of the present application further comprises: The method may further include a step S21 in which the terminal periodically measures a synchronization signal or a reference signal on the downlink A.

[0078] Optionally, the terminal 1) A link through which a terminal transmits information directly to a LIS or relay device that includes an active receiving module or an active transmitting / receiving module; 2) A link in which a terminal indirectly transmits information to a LIS or a relay device, and a network side device receives information transmitted from the terminal and transfers it to the LIS or the relay device (the uplink is a wireless logical link from the terminal to the LIS or the relay device, and an intelligent surface in which a small number of active transmission and reception modules are integrated can receive the uplink signal of the terminal); 3) A link where the terminal transmits information directly to the network side device; 4) A link by which a terminal indirectly transmits information to a network side device, and an LIS or relay device receives information transmitted from the terminal and forwards it to the network side device (an uplink is a logical link from the intelligent surface to the network side device, and the LIS or relay device passes the received terminal information to the network side device, and the actual physical channel between the LIS or relay device and the network side device may be a wireless link or a wired link). The information is transmitted via at least one uplink.

[0079] The first operating state in this method 2-3 may be an operating state that the terminal enters when performing high-speed data transmission, and in a specific application scenario, the terminal enters this first operating state based on a first signaling indication of a second operating state (the terminal is in an idle state or a deactivated state in downlink A) or based on a second signaling indication of a second operating state (the terminal is on downlink C or downlink A and in a connected state).

[0080] Here, when entering the first operating state based on the second signaling indication, the terminal may determine beam / SSB / CSI-RS information of the first operating state to be preferentially measured based on beam / SSB / CSI-RS information of the second operating state (that is, the terminal is in an idle state or a deactivated state in downlink A) and a first mapping table, where the first mapping table is a table that shows the beam / SSB / CSI-RS information of the first operating state (that is, the terminal is in an idle state or a deactivated state in downlink A) and the beam / SSB / CSI-RS information of the first operating state to be preferentially measured. two The first mapping table defines a mapping relationship, for example a QCL relationship, between the beam / SSB / CSI-RS information of the working states of the terminal and the beam / SSB / CSI-RS information of the working states of the terminal. Since the mapping relationship between different working states is defined in the first mapping table, the terminal can more quickly perform downlink measurement and synchronization and more quickly realize state switching.

[0081] Optionally, the mobility management in this first operating state may be that the terminal periodically measures the downlink A synchronization signal / reference signal.

[0082] Optionally, the terminal monitors a first signaling, such as paging, on downlink A, where the paging indicates to the terminal whether or not it needs to enter the second operating state.

[0083] The switching methods in the above methods 2-1 to 2-3 are switching between three types of operating states, and the following will explain switching methods between more than three types of operating states.

[0084] In the method 3-1, when the LIS is an active LIS or the relay device is an active relay device, and the first working state is that the terminal is in an idle state or a deactivated state in the downlink A, step S30 in the embodiment of the present application 2 The method for switching the terminal from operating in a first operating state to operating in a second operating state is as follows: Step S30 in which the terminal monitors a seventh signaling on the downlink A. 2 -101, A step S30 in which the terminal switches from operating in the first operating state to operating in the second operating state based on the seventh signaling. 2 -102, where the second operating state is that the terminal enters a target downlink and is in a connected state, and the target downlink is at least one of downlink A, downlink B, and downlink C.

[0085] According to this method 3-1, when the LIS is an active LIS or the relay device is an active relay device, and the first working state is that the terminal is in an idle state or a deactivated state in the downlink A, step S30 in the embodiment of the present application 2The manner in which the terminal switches from operating in the first operating state to operating in the second operating state in the above may further include the terminal switching from operating in the first operating state to operating in the second operating state when a fifth timer in the first operating state times out, where the second operating state is that the terminal enters a target downlink and is in a connected state, and the target downlink is at least one of downlink A, downlink B, and downlink C. When the terminal receives a scheduling signaling in the first operating state, for example a scheduling signaling indicating a new packet, the terminal starts or restarts the fifth timer.

[0086] For this method 3-1, in a specific application scenario, the method may further include: the terminal periodically measuring a synchronization signal / reference signal of downlink A; and the terminal monitoring a first signaling, such as paging, on downlink A, where the first signaling instructs the terminal whether it needs to enter one of the other N-1 types of states.

[0087] In the method 3-2, when the LIS is an active LIS or the relay device is an active relay device, and the first working state is that the terminal is in an idle state or a deactivated state in the downlink C, step S30 in the embodiment of the present application 2 The method for switching the terminal from operating in a first operating state to operating in a second operating state is as follows: Step S30 in which the terminal monitors an eighth signaling on the downlink A. 2 -111, A step S30 in which the terminal switches from operating in the first operating state to operating in the second operating state based on the eighth signaling. 2 -112, where the second operating state is that the terminal has entered the target downlink and is in a connected state.

[0088] Regarding the above method 3-2, in a specific application scenario, the terminal may periodically measure a synchronization signal / reference signal of downlink C (for an active LIS), and the terminal may monitor a second signaling, such as paging, on downlink C, where the second signaling instructs the terminal whether it needs to enter one of the other N-1 types of states.

[0089] In the manner 3-3, when the LIS is an active LIS or the relay device is an active relay device, and the first working state is that the terminal enters the target downlink and is in a connected state, step S30 in the embodiment of the present application 2 The method for switching the terminal from operating in the first operating state to operating in the second operating state is as follows: Step S30 in which the terminal monitors a ninth signaling on the target link. 2 -121, A step S30 in which the terminal switches from operating in the first operating state to operating in the second operating state based on the ninth signaling. 2 -122, where the second operating state is that the terminal is in an idle state or a deactivated state in downlink C, or the second operating state is that the terminal is in an idle state or a deactivated state in downlink A or downlink C.

[0090] Optionally, according to this method 3-3, step S30 in the embodiment of the present application 2may be that the terminal switches from operating in the first operating state to operating in the second operating state when a sixth timer in the first operating state times out, where the second operating state is that the terminal is in an idle state or a deactivated state in downlink C, or the second operating state is that the terminal is in an idle state or a deactivated state in downlink A or downlink C. The terminal starts or restarts the sixth timer when it receives a scheduling signaling in the first operating state, for example a scheduling signaling indicating a new packet.

[0091] Alternatively, the terminal periodically measures the synchronization signal or the reference signal of downlink C or downlink A.

[0092] Optionally, the terminal 1) A link through which a terminal transmits information directly to a LIS or relay device that includes an active receiving module or an active transmitting / receiving module; 2) A link in which a terminal indirectly transmits information to a LIS or a relay device, and a network side device receives information transmitted from the terminal and transfers it to the LIS or the relay device (the uplink is a wireless logical link from the terminal to the LIS or the relay device, and an intelligent surface in which a small number of active transmission and reception modules are integrated can receive the uplink signal of the terminal); 3) A link where the terminal transmits information directly to the network side device; 4) A link by which a terminal indirectly transmits information to a network side device, and a link by which an LIS or relay device receives information transmitted from the terminal and forwards it to the network side device (the uplink is a logical link from the intelligent surface to the network side device, and the LIS or relay device passes the received terminal information to the network side device, and the actual physical channel between the LIS or relay device and the network side device may be a wireless link or a wired link), and transmits information via at least one uplink.

[0093] Regarding the above method 3-3, in a specific application scenario, the terminal enters a connected state and selects at least one of the downlinks as a target downlink and at least one of the uplinks as a target uplink based on a first signaling of the second operating state (the terminal is in an idle state or a deactivated state in downlink C) or a second signaling of the second operating state (the terminal is in an idle state or a deactivated state in downlink A or downlink C), such as a paging instruction, or based on a signaling instruction of another sub-state of the connected state (operating on another downlink).

[0094] In an optional embodiment of the embodiment of the present application, the method steps of the embodiment of the present application include: The method may further include a step S41, in which, when switching from the first operating state to the second operating state, the terminal determines target information in the second operating state based on the target information in the first operating state and the first mapping table; Wherein, the target information includes at least one of beam information, a synchronization signal block SSB, a channel state information reference signal CSI-RS, and quasi-co-location QCL information; The first mapping table is used to indicate a mapping relationship between the target information in the first operating state and the target information in the second operating state.

[0095] In an optional embodiment of the embodiment of the present application, the method steps of the embodiment of the present application include: The method may further include a step S42 in which, when switching from the first uplink to the second uplink, the terminal determines target information of the second uplink based on the target information of the first uplink and the second mapping table; Here, the target information includes at least one of beam information and QCL information, The first uplink or the second uplink, 1) A link through which a terminal transmits information directly to a LIS or relay device that includes an active receiving module or an active transmitting / receiving module; 2) A link in which a terminal indirectly transmits information to a LIS or a relay device, and a network side device receives information transmitted from the terminal and transfers it to the LIS or the relay device (the uplink is a wireless logical link from the terminal to the LIS or the relay device, and an intelligent surface in which a small number of active transmission and reception modules are integrated can receive the uplink signal of the terminal); 3) A link where the terminal transmits information directly to the network side device; 4) A link in which a terminal indirectly transmits information to a network side device, and an LIS or relay device receives information transmitted from the terminal and transfers it to the network side device (an uplink is a logical link from an intelligent surface to a network side device, and an LIS or relay device passes the received terminal information to the network side device, and an actual physical channel between the LIS or relay device and the network side device may be a wireless link or a wired link); Here, the second mapping table is used to indicate the mapping relationship between the target information in the first working state and the target information in the second working state.

[0096] Regarding the above steps S41 and S42, in a specific application scene, the following may be performed: When switching from downlink C (idle state, inactive state, or connected state) to downlink A (idle state, inactive state, or connected state), the terminal may determine, based on (the strongest N, where N is greater than or equal to 1) downlink C beam / SSB / CSI-RS information and a first mapping table, a beam / SSB / CSI-RS information of downlink A to be preferentially measured, where the first mapping table defines a mapping relationship, such as a QCL relationship, between the beam / SSB / CSI-RS of downlink C and the beam / SSB / CSI-RS information of downlink A; Conversely, when switching from downlink A (idle state, inactive state, or connected state) to downlink C (idle state, inactive state, or connected state), the terminal may determine, based on the (N strongest, N is 1 or more) beam / SSB / CSI-RS information of downlink A and a first mapping table, the beam / SSB / CSI-RS information of downlink C to be preferentially measured, where the first mapping table defines a mapping relationship, for example a QCL relationship, between the beam / SSB / CSI-RS of downlink C and the beam / SSB / CSI-RS information of downlink A; When switching from uplink 1 or 2 (idle state, inactive state, or connected state) to uplink 3 or 4 (idle state, inactive state, or connected state), the terminal may determine a transmission beam of uplink 3 or 4 to be preferentially used based on the (N strongest, N being 1 or more) transmission beam information of uplink 1 or 2 and a second mapping table (the advantage is that switching to a different uplink is faster); Here, the second mapping table defines a mapping relationship, for example, a QCL relationship, between the transmission beam of uplink 1 or 2 and the transmission beam of uplink 3 or 4; Conversely, when switching from uplink 3 or 4 (idle state, inactive state, or connected state) to uplink 1 or 2 (idle state, inactive state, or connected state), the terminal may determine a transmission beam of uplink 1 or 2 to be preferentially used based on the (strongest N, where N is 1 or more) transmission beam information of uplink 3 or 4 and the second mapping table (the advantage is that switching to a different uplink is faster); Here, the second mapping table defines a mapping relationship, for example, a QCL relationship, between the transmission beam of uplink 1 or 2 and the transmission beam of uplink 3 or 4; Here, uplink 1 is the link from the terminal to the LIS (assuming the LIS is active), uplink 2 is the link from the terminal to the LIS and then to the base station (assuming the LIS is active), uplink 3 is the link from the terminal to the base station and then to the LIS, and uplink 4 is the link from the terminal to the base station.

[0097] In addition, since the LIS is passive and does not have the ability to receive wireless information, the terminal cannot feed back ACK / NACK to the LIS in the downlink B of the LIS. In response to this, the embodiment of the present application further provides the following scheme. In step S51, the terminal feeds back ACK / NACK related information to the base station, and the base station transmits the ACK / NACK to the LIS. For example, the base station and the LIS are connected by wire or wirelessly; Here, the ACK / NACK related information further includes an indication of which data packet is sent to the LIS and at what time the ACK / NACK is sent, or if it follows a pre-defined mapping rule, it does not need to be indicated each time, In step S52, the terminal feeds back channel state feedback information, such as CQI, of the LIS link B to the base station, and the base station transfers it to the LIS; In step S53, the terminal transmits ACK / NACK / channel state feedback information for the LIS link, etc., either separately or in addition to other data that the terminal transmits to the base station.

[0098] According to the embodiment of the present application, in the case of no data transmission or low-speed data transmission, the terminal only needs to receive signals / data of downlinks B and C and a small amount of measurements of downlink A, and the reception of downlinks B and C is simpler than downlink A, which is favorable for the terminal's energy saving. In addition, direct communication between the terminal and the LIS, i.e., using downlink C and uplinks 1 and 2, is more flexible than direct communication between the base station and the terminal, and the link quality is better in some conditions because the LIS is closer to the terminal.

[0099] It should be noted that in the working state switching method according to the embodiment of the present application, the execution body may be a working state switching device or a control module for executing the working state switching method in the working state switching device.
