Description

[Technical Field]

[0001] TECHNICAL FIELD This application relates to the field of communications technology, and more particularly to wireless communication methods, devices and apparatus. [Background technology]

[0002] With the development of wireless communication technology, users' requirements for wireless communication speed and quality are also increasing. Particularly in scenarios where hotspot service coverage extension services exist, such as VR services, AR services, and video services, using only the beamforming technology of the base station cannot provide a sufficient communication speed to the terminal. Therefore, in the above situation, it is necessary to further introduce auxiliary nodes, such as intelligent surfaces, into the wireless communication network to enhance the terminal's received signal strength.

[0003] In particular, in the wireless communication process, due to the occurrence of terminal movement or object fluctuation in the communication environment, the equivalent channel from the base station to the terminal changes over time. Therefore, the pre-configured frequency domain resource from the base station to the terminal may be in a frequency selective deep fading situation after a certain period of time. Therefore, it is very necessary to improve the problem of frequency selective deep fading by using intelligent surface.

[0004] However, the channel estimation process of intelligent surfaces is more complex than traditional channel estimation, making it difficult to update the transmission beam state of intelligent surfaces in real time. Furthermore, because the multipath phase and amplitude of wireless channels change randomly and slowly over time, affected by the movement and change speed of terminals and environmental objects, in the frequency domain, once a certain resource block falls into a frequency-selective fading state, this resource block will remain in a frequency-selective fading state for a certain period of time until the multipath channel changes to another state, resulting in poor communication quality. Because the channel estimation process based on intelligent surfaces takes a long time and requires additional time to update the operating state of the intelligent surface based on the channel estimation results, the operating state of the intelligent surface obtained with outdated channel information cannot achieve optimal channel expansion performance.

[0005] Therefore, how to control the intelligent surface to adjust the frequency selective fading situation in the wireless communication process in a timely and effective manner with low computational complexity has become an urgent problem to be solved in this field. Summary of the Invention [Problem to be solved by the invention]

[0015] The following clearly describes the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application fall within the scope of protection of the present application.

[0016] The terms "first," "second," etc. in the specification and claims of this application are intended to distinguish between similar objects and are not intended to describe a particular order or sequence. It should be understood that terms used in this manner are interchangeable where appropriate, so that embodiments of this application may be performed in orders other than those illustrated or described herein, and that objects distinguished by "first" and "second" are generally of the same type and do not limit the number of objects; for example, a first object may be one or more. Furthermore, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the related objects.

[0017] To facilitate understanding of the embodiments of the present application, some of the terms used in the embodiments of the present application will be explained below.

[0018] 1. Intelligent Surface

[0019] A reconfigurable intelligent surface (RIS) is an auxiliary communication device. As shown in Figure 1, multiple device units are mounted on the intelligent surface. The size of the RIS device units is typically subwavelength scale, smaller than the wavelength corresponding to the operating frequency point. The RIS device units are regularly arranged on a flat or curved surface to form a RIS device unit array. Here, each RIS device unit includes an independently controllable element controlled by a background RIS control module. Under the control of the RIS control module, the RIS device unit can dynamically or semi-statically adjust its electromagnetic characteristics to affect the reflection or reflection behavior of electromagnetic waves incident on the RIS device unit. Therefore, the intelligent surface can realize functions such as beam scanning and beamforming by manipulating the reflected or refracted electromagnetic signals. Because the intelligent surface only includes inactive device units, the transmitted signal maintains signal correlation with the source transmission signal, allowing coherent superposition of multipath signals at the receiving end. In a wireless communication network assisted by an intelligent surface, the transmission beam of the intelligent surface may be adjusted to the terminal or the area where the terminal is located through beam training or simulated beamforming, and the state of the transmission beam of the intelligent surface may be changed in a timely manner to improve the frequency-selective deep fading situation of the communication link. In particular, other devices with coherent transmission of wireless signals, such as backscatter, coherent transmission repeaters, etc., may also adjust the state of the transmission signal to improve the frequency-selective deep fading of the communication link.

[0020] 2. Beam control principle based on intelligent surface

[0021] As shown in Figure 2, the beam control principle based on intelligent surface is specifically as follows:

[0022] Taking the phase-controlled intelligent surface as an example, the ideal control phase of device unit (m, n) is as follows:

number

[0023] Here, for a 1-bit discrete phase control intelligent surface, the ideal compensation phase may be mapped to a discrete phase by discretization processing, for example,

number

[0024] It should be noted that the techniques described in the embodiments of the present application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be applied to other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in the embodiments of the present application are always used interchangeably, and the described techniques may be used in the above-mentioned systems and radio technologies as well as other systems and radio technologies. Although the following description describes a New Radio (NR) system for illustrative purposes and uses NR terminology in most of the description below, these techniques may also be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.

[0025] 3 shows a block diagram of a wireless communication system to which the embodiments 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 referred to as a terminal device or user equipment (UE), and may be a terminal side device such as a mobile phone, a tablet personal computer (PDA), a laptop computer (also called a notebook computer), a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), a wearable device, a vehicle-mounted equipment (VUE), a pedestrian-mounted equipment (PUE), etc., and wearable devices include a smart watch, a bracelet, an earphone, glasses, etc. It should be noted that the embodiments of the present application do not limit the specific type of the terminal 11. The network side device 12 may be a base station or a core network, where the base station may be called a Node B, an evolved Node B, an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, first device S), an extended service set (Extended Service Set, ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting receiving point (TRP), or any other suitable term in the art, as long as similar technical effects are achieved, and the base station is not limited to a specific technical term. For illustrative purposes, the embodiments of this application only take base stations in an NR system as examples, but do not limit the specific type of base station.

[0026] The following describes in detail the wireless communication, device and equipment according to the embodiments of the present application through several embodiments and application scenarios thereof in conjunction with the drawings.

[0027] In related technology, the 5G NR protocol provides the function of simulated beam scanning, the basic flow of which is that the base station sequentially transmits signals in different beams at different times, the terminal receives the signals in a fixed receiving beam, and then selects the optimal transmitting beam and reports it to the base station.

[0028] The beam scanning flow defined by 5G NR or the channel estimation and beamforming flow designed for the intelligent surface device can align the transmitted signal beam of the intelligent surface to the terminal to achieve the expected reception effect, for example, to maximize the signal energy received by the terminal within the operating frequency band.

[0029] However, as shown in Figure 4, in the wireless communication process, the equivalent channel from the base station to the terminal changes over time due to the occurrence of terminal movement or object movement in the communication environment, so the pre-configured frequency domain resource from the base station to the terminal may be in a situation of frequency deep fading after a certain period of time.

[0030] The intelligent surface device may provide a portion of the multipath signal for the terminal and control the phase and strength of the multipath signal. Changing the phase or strength of a portion of the multipath channel may reduce the impact of frequency-selective fading on data transmission. If the communication system knows all channel information, the base station may adjust the state of the transmission beam of the intelligent surface so that the received signal strength is maximized on the frequency resource to which the terminal is scheduled (i.e., the transmission signal of the intelligent surface is forward-convolved with the reflected / scattered signals of normal objects in the multipath environment). Therefore, after the intelligent surface is introduced, controlling the phase of a portion of the multipath in the multipath channel may improve frequency-selective fading on the scheduled frequency resource.

[0031] Regarding the control method of the base station for the intelligent surface, the related art attempts to control the intelligent surface using closed-loop scheduling or open-loop hopping diversity technology. Closed-loop scheduling refers to the frequency resource that is scheduled for the terminal based on uplink or downlink channel measurement to avoid frequency-selective deep fading. Open-loop hopping diversity maps data transmitted in a frequency hopping manner to two different time-frequency resources when the current channel condition is unknown, thereby reducing the probability of encountering frequency-selective deep fading and improving the robustness of data transmission.

[0032] However, when the signal phase of a base station or a terminal changes, it affects the phase changes of all multipaths in a multipath environment. Therefore, the conventional communication system cannot achieve the purpose of individually controlling a part of the multipath. Accordingly, the closed-loop scheduling or open-loop hopping diversity technology used in the related art has difficulty in effectively avoiding frequency-selective deep fading.

[0033] In order to achieve accurate control of the intelligent surface transmission beam, the base station and the terminal need to perform complex channel measurement and feedback operations, then calculate the working state of the intelligent surface according to the measurement results and send it to the intelligent surface, and then schedule corresponding frequency resources for the terminal. The time overhead of this series of closed-loop control flow is higher and more complex than the closed-loop control flow of the 5G NR system, which affects the transmission efficiency of the system.

[0034] In particular, in multi-user scenarios, multiple terminals requiring service exist within the coverage area of ​​the intelligent surface's transmission beam. Because intelligent surfaces can only achieve simulated beam forwarding, multiple users often need to share communication resources using time-division multiplexing or frequency-division multiplexing. Because the multipath environments of multiple terminals in the same area differ and the frequency resource scheduling results differ, the phase requirements for the intelligent surface's transmission beam also differ. It is difficult for an intelligent surface to simultaneously meet the communication needs of multiple users. Even if multi-user channel information is obtained through closed-loop channel measurement, the system may not be able to determine the operating state of a single intelligent surface that simultaneously meets the channel needs of all multiple users. As shown in Figure 5, even in a multi-user scenario (e.g., the intelligent surface coverage area in Figure 5 includes terminal 1, terminal 2, and terminal 3), each terminal's phase requirements for the transmission beam are different. The transmission beam of the intelligent surface is a simulated beam, and it cannot simultaneously guarantee optimal beams for multiple terminals, which affects the overall capacity of the wireless communication system.

[0035] To overcome the above problems, an embodiment of the present application provides a wireless communication method, as shown in Figure 6. The wireless communication method according to the embodiment of the present application includes the following steps S101 to S102.

[0036] In S101, the first device configures N operating states for the second device.

[0037] Here, N is an integer greater than 1.

[0038] In an embodiment of the present application, the first device may be a network device (eg, a base station) or a terminal.

[0039] In an embodiment of the present application, the second device is a device for assisting the first device in wireless communication, where the second device may be a coherent transmission device or a non-coherent transmission device.

[0040] Illustratively, the second device may be an intelligent surface device or a relay device or a backscatter device.

[0041] It should be noted that the transmit signal of the intelligent surface device is coherent with other multipath signals, i.e., has a stable frequency relative to the transmitting source signal. For the repeater device, the frequency or phase of this amplified signal is randomly offset, resulting in incoherent superposition with other multipath signals. Note that the application scenario of the repeater device is for coverage extension or cell edge coverage, where the energy of other multipath signals is relatively weak, and the performance gain of the transmit signal switching diversity method is not significant. However, in hotspot extension scenarios, the repeater device can be used to extend the hotspot area or user performance, so the repeater device can be used as the second device in the above case. For the repeater device, the effect of the amplifier approximates continuous change within a single data transmission time period (one or more consecutive slots), so transmit diversity can be realized. Transmit diversity can also be achieved by accessing different phase-shifting devices after the amplifier to achieve simulated beam control and phase control.

[0042] As can be understood, when the second device is an intelligent surface device, the N operating states of the second device may be a combination of the operating states of all intelligent surface devices in the second device.

[0043] In an embodiment of the present application, the second device performs an operating state change within a slot or between slots based on the N operating states and the operating times corresponding to the operating states configured for it by the first device. As can be understood, the configured N operating states may be configured to appear periodically or semi-statically, or may be configured to dynamically indicate those within a certain time period.

[0044] In an embodiment of the present application, the second device switches between the N operating states within the duration of one data transmission based on the N operating states for which the first device is configured.

[0045] For example, the duration of one data transmission may include multiple time units, and the second device may switch between the N operating states within each of the multiple time units.

[0046] As can be understood, the working state of the second device has a one-to-one correspondence with the control information or control mode of the second device.

[0047] Illustratively, when the second device is an intelligent surface device, the N operating states of the second device may correspond to spatial energy distribution states of the transmission beam of the second device.

[0048] In S102, the first device transmits data to the third device.

[0049] Here, the time of data transmission spans the operating time of the N operating states of the second device, which may be a plurality of OFDM symbols or a plurality of slots.

[0050] In an embodiment of the present application, the third device may be a terminal.

[0051] Here, the N working states of the second device are wireless signal transfer states of the second device to the first device or the third device.

[0052] Optionally, in an embodiment of the present application, different operating states in the N operating states correspond to different operating modes of the second device.

[0053] Illustratively, taking the second device as an intelligent surface device, when the incident signal direction of the second device is fixed, different operating states in the N operating states of the second device can realize different transmission beams.

[0054] In other words, different ones of the N operating states correspond to different transfer beams transferred by the second device, which may include at least one of transfer beams with different phases, transfer beams with different intensities, transfer beams with different directions, transfer beams with different widths, transfer beams with different gains, and transfer beams with different secondary lobe energies.

[0055] Optionally, in an embodiment of the present application, the wireless communication method is an open-loop diversity wireless communication method based on a second device (for example, an intelligent surface).

[0056] Optionally, in an embodiment of the present application, the wireless communication method is a wireless communication method of time domain diversity transmission mode.

[0057] Optionally, in the embodiment of the present application, the second device is an auxiliary communication device, which is controlled by the first device, and thereby performs signal forwarding operations according to different working states among N working states in different time periods of data transmission in the process of uplink data transmission or downlink data transmission, and the first device can change the channel between the first device and the third device by configuring the N working states for the second device.

[0058] Optionally, in the embodiment of the present application, when the first device performs downlink data transmission with a third device, the above S102 includes the following S102a or S102b:

[0059] In S102a, the first device performs data transmission with the third device by mapping one redundant version of the data to time-frequency resources of multiple time periods.

[0060] In S102b, the first device performs data transmission with the third device by mapping at least two redundancy versions to a plurality of time-period time-frequency resources, respectively.

[0061] As can be understood, when a first device performs downlink data transmission with a third device, the first device needs to consider the switching time delay between different operating states of the second device. For example, the first device needs to consider the time domain resources occupied by the switching time delay. For example, during the symbol-level switching time delay, the first device may not transmit data and notify the third device.

[0062] In the embodiment of the present application, it is necessary to ensure that at least one reference signal (e.g., DMRS) is used for channel estimation and demodulation decoding within each time period of the second device's operation state, so that the third device receives downlink signals according to the configured time period and performs channel estimation and demodulation decoding.

[0063] In an embodiment of the present application, a first device may configure N working states for a second device, where N is an integer greater than 1. The first device performs data transmission with a third device, and the time of this data transmission spans the working time of the N working states of the second device. Here, the N working states of the second device are wireless signal transfer states of the second device to the first device or the third device. Thus, the second device can transfer wireless signals of the first device or the third device, respectively, according to at least two working states configured for the first device, so that the channel between the first device and the third device changes. of transfer death , thereby timely and effectively adjusting the frequency resource scheduled by the first device to the frequency selective deep fading situation encountered, and ensuring communication quality and efficiency.

[0064] It should be noted that the embodiments of the present application can realize transmission diversity. In a scenario where a first device and a third device communicate through a second device, in a single uplink or downlink transmission process, the working state of the second device can be switched according to a predetermined rule to achieve the purpose of changing the channel state between the first device and the third device, and the first device or the third device can receive uplink or downlink signals under different channel states on the configured frequency resources, thereby achieving transmission diversity.

[0065] Optionally, in a multi-user scenario, different third devices have different requirements for the second device, and open-loop diversity for second device operating state switching can avoid frequent channel estimation, ensure communication efficiency, flexibly support multi-user scheduling transmission, and ensure that when multi-user communication is performed, the transmission beam of at least one second device can provide forward gain to the user.

[0066] Optionally, in an embodiment of the present application, the first device may configure N operating states for the second device according to the status of the second device, which are adapted to the status of the second device.

[0067] Illustratively, the above S101 includes the following S101a to S101b.

[0068] In S101a, the first device acquires device information of the second device and channel measurement results of the target channel.

[0069] As can be seen, after the second device accesses the cell (i.e., the second device completes the synchronization flow and maintains time-frequency synchronization with the first device), the second device reports its device information to the first device, and in response, the first device obtains the device information reported by the second device.

[0070] Optionally, in the embodiment of the present application, the device information includes a device type, and the device type can be selected from the following: a pure inactive cell intelligent surface, a mixed type intelligent surface of active cell and inactive cell, a repeater with a function of wireless signal coherent transmission, and a wireless signal non-coherent transmission. nt It includes at least one of a relay having a forwarding function.

[0071] Optionally, in an embodiment of the present application, the device information includes a device function, which is a control method for a radio signal parameter of the second device, and the device function includes at least one of phase control, amplitude control, and polarization direction control.

[0072] Optionally, in an embodiment of the present application, the device information includes a device controlled quantization precision, and the device controlled quantization precision is a control radio signal parameter controlled by n-bit control information, where n is an integer equal to or greater than 1.

[0073] For example, assume that the device function of the second device includes a phase control function, and the device control quantization precision of the second device is a control radio signal parameter controlled by 1-bit control information. Accordingly, the control information "0" of the second device may be considered to correspond to the phase of the second device reflected signal being continuous with the phase of the incident signal, and the control information "1" of the second device may be considered to correspond to a phase difference of 180° between the phase corresponding to the second device reflected signal and the phase of the incident signal, or a phase difference of 180° between the second device reflected signal phase corresponding to the control information "0" and the reflected signal phase corresponding to the control information "1".

[0074] For example, suppose the device function of the second device includes a phase control function, and the device control quantization precision of the second device is controlled by a control radio signal parameter, which is control information greater than 1 bit. The first device can obtain the device information of the second device from a product specification, a protocol definition, or an active report from the second device. This allows the first device to determine the phase state of the transmission signal corresponding to each bit of information.

[0075] In an embodiment of the present application, the target channel is a wireless channel between the second device and the first device or a third device.

[0076] Optionally, in an embodiment of the present application, the target channel includes S first channels between the second device and S third devices, where one third device corresponds to one first channel, and the channel measurement result is obtained based on the channel measurement results of the S first channels, where S is an integer greater than 1.

[0077] As can be seen, the channel measurement results for the target channel can be obtained by a channel measurement algorithm.

[0078] In one example, if the second device is an intelligent surface, the channel measurements can be obtained based on a simulated beam scan of the second device.

[0079] In another example, if the second device is an intelligent surface, the channel measurements can be obtained based on a channel decomposition of the second device channel perspective.

[0080] In S101b, the first device configures N working states for the second device based on the device information and the channel measurement results.

[0081] In an embodiment of the present application, according to the above device information, the first device may obtain the number of operating states required to configure for the second device, and based on the above channel measurement results, the first device can obtain a set of operating states required to configure for the second device.

[0082] In this way, the first device may configure an operating state for the second device based on the device information and channel measurement results of the second device, which is adapted to the situation of the second device, thereby achieving the purpose of further improving the efficiency and quality of communication between the first device and the third device by the second device.

[0083] Optionally, in an embodiment of the present application, before the above S101b, the wireless communication method includes the following S103 or S104.

[0084] In S103, the first device transmits P reference signals to the third device.

[0085] In S104, the first device receives P reference signals transmitted by the third device.

[0086] Here, the P reference signals are signals transmitted by the second device using the P predefined operating states, respectively.

[0087] In the embodiment of the present application, the target channels include channels corresponding to the P reference signals.

[0088] In the embodiments of the present application, P is an integer of 1 or greater.

[0089] As can be seen, in order to perform channel measurement by simulated beam scanning, during the channel measurement stage, the first device or the third device needs to transmit the reference signal to the other device multiple times, where the reference signal is forwarded between the first device and the third device by the second device.

[0090] Here, the second device has a plurality of predefined operating states (which may be understood as fixed operating states).

[0091] In one example, a first device transmits P reference signals to a third device, and in response, after receiving the P reference signals from the first device, the second device transfers the P reference signals to the third device using each operating state of the P predefined operating states.

[0092] In another example, a first device receives P reference signals transmitted by a third device, and in response, after receiving the P reference signals from the third device, the second device transmits the P reference signals to the first device using each operating state among the P predefined operating states.

[0102] Optionally, in the embodiment of the present application, based on the above S103 or S104, the above S101b includes the following S101b3:

[0103] In S101b3, the first device dynamically generates N operating states based on the measurement results of the P reference signals.

[0104] In an embodiment of the present application, the first device may generate N operating states based on the measurement results of the P reference signals in a dynamic manner based on the measurement results of the P reference signals.

[0105] Optionally, in the embodiment of the present application, based on the above S103 or S104, the above S101b includes at least one of the following S101b4 to S101b6.

[0106] In S101b4, the first device determines the number of candidate operating states based on the device information.

[0107] In the embodiment of the present application, the number of candidate operating states may be one or more.

[0108] Optionally, in the embodiment of the present application, when the number of candidate working states is one, the candidate working state is the working state with the best communication quality.

[0116] As can be seen, the target after the first offset is set of Signals and targets transmitted in predefined operating states of Under predefined operating conditions, the spatial energy distribution of the transmitted signals remains unchanged, but a corresponding change occurs in the phase between them.

[0123] Here, one beam direction corresponds to at least one operating state, where M is 1 or more.

[0124] As can be appreciated, due to the effects of multipath signals, a first device can determine multiple signal directions to a second device, and the energy intensity of each signal direction may differ.

[0125] In S101b8, the first device determines N operating states according to the beam direction.

[0128] Here, the N operating states include the first operating state and the first operating state after the second offset amount is set.

[0129] In other words, if a first device uses a single signal direction or the direction of the strongest signal as the beam direction in which a second device will transmit a signal, a scheme based on the offset amount may be used to generate candidate operating states for the second device.

[0130] Optionally, in the embodiment of the present application, when the beam directions are at least two beam directions, the N operating states include an operating state corresponding to each beam direction in the at least two beam directions.

The time periods may be multiple symbols, multiple slots, or multiple subframes. The second device adjusts its operating states based on the configuration of the first device.

[0142] Here, the first device needs to configure data transmission parameters, i.e., frequency resources, for the third device. Then, the first device instructs the second device to transmit data or signals using a transmission diversity mode of operating state switching. Specifically, in one data transmission, the first device configures a time resource for one data transmission for the third device. Multiple time periods included in this time resource correspond to time periods of candidate operating states of the second device, respectively.

[0143] Optionally, in an embodiment of the present application, when a first device configures a transmission resource for a third device, it does not need to indicate whether the current transmission is a normal transmission or a transmission that is switched based on the operating state of the second device.

[0144] Optionally, in the embodiment of the present application, it is necessary to ensure that at least one reference signal (e.g., DMRS) is used for channel estimation and demodulation / decoding within each operating state time period of the second device, so that the third device does not need to perform channel measurement and feedback.

[0145] In this way, the first device rationally configures the data transmission parameters required for wireless communication for the second device and the third device, respectively, ensures that the second device and the third device coordinate and adapt to each other, and improves the quality and efficiency of data transmission.

[0148] In S106, when the first device performs downlink data transmission with the third device, the first device notifies the third device of at least one of diversity mode on, diversity mode time zone configuration, protocol-predefined configuration, and dynamic / semi-static configuration.

[0149] In this way, the first device can notify the third device of the relevant status or information of the diversity mode, so that the third device can better match with the second device based on the relevant status or information of the diversity mode, thereby achieving the purpose of further improving communication quality.

[0150] It should be noted that the execution order of S106 is not limited in the embodiments of the present application. In one way, S106 may be executed first and then S102 may be executed, or in another way, S102 and S106 may be executed synchronously.

[0152] In S107, the first device acquires the switching time period of the operating state of the second device determined by the third device.

[0153] Here, the switching time period is determined based on at least one of configuration information of dynamic scheduling information, semi-static configuration information of radio resource control (RRC) or media access control layer control unit (MAC CE) commands, and information predefined by a protocol.
