Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) The present invention claims priority to a Chinese patent application, application number 202010693760.0, entitled "Terminal information acquisition method, terminal and network side equipment", filed with the China Patent Office on July 17, 2020, the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the technical field of wireless communication, and in particular to a terminal information acquisition method, a terminal, and a network side device. [Background technology]

[0003] Intelligent surfaces are an emerging technology, and intelligent surface devices are sometimes called Large Intelligent Surfaces (LIS), Smart Reflect Arrays (SRA), Reconfigurable Reflect Arrays (RRA), or Intelligent Reflecting Surfaces (IRS).

[0004] An intelligent reflective surface IRS is an electromagnetic metamaterial or metasurface that is composed of a large number of low-cost passive reflective elements, each of which can independently induce a change in the amplitude and / or phase and / or polarization of the incident signal, thus rearranging the radio propagation environment by controlling reflections.

[0005] Compared with traditional active relay communication, IRS does not use an active transmission module, but only reflects the received signal. Active relay communication usually operates in half-duplex mode, and its spectral efficiency is lower than that of IRS operating in full-duplex mode. Compared with traditional backscatter communication (e.g., Radio Frequency Identification, RFID), IRS, as a passive reflecting device, does not transmit its own information, and is only used to facilitate existing communication links. IRS is a passive array and is generally used as a reflectarray. Compared with massive multiple input multiple output (MIMO) technology, IRS has the advantages of lower hardware cost, lower transmission loss, and more suitable for millimeter wave band (mmWave).

[0006] In some cases, a terminal (UE) is within the coverage of an intelligent surface device or repeater, but beyond the coverage of a base station associated with the intelligent surface or repeater, whereas the intelligent surface device or repeater generally does not acquire information but only transmits, and therefore does not know information about the terminal.

[0040] Hereinafter, the technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is to be understood that the described embodiments are only a part of the embodiments of the present application, and are not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without any creative efforts shall fall within the scope of protection of the present application.

It should be understood that the terms used in this manner may be substituted for each other where appropriate, so that the embodiments of the present application may be performed in an order other than that shown or described herein, and that the objects distinguished by "first" and "second" are generally of one type, and the number of objects is not limited, for example, the first object may be one or more. In addition, "and / or" in the specification and claims means at least one of the objects connected, and the symbol " / " generally means that the related objects before and after are in an "or" relationship.

[0042] It should be noted that the technology described in the embodiments of the present application is not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, and is also applicable 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 may often be used interchangeably. The technology described may be used in the above-mentioned systems and radio technologies, as well as in other systems and radio technologies. However, in the following description, a New Radio (NR) system will be described for illustrative purposes, and NR terminology will be used in much of the following description, but these techniques may also be applied to systems other than NR systems, such as 6th generation (6G) systems. th It is also applicable to 6G (Generation, 6G) communication systems.

[0043] 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, a network side device 12, and a first network node 13. The terminal 11 may be called a terminal device or a user equipment (UE), and the terminal 11 may be a terminal side device such as a mobile phone, a tablet personal computer, 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 device (VUE), a pedestrian terminal (PUE), etc., and the wearable device includes a wristband, a headphone, a pair of glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application. The network side device 12 may be a base station or a core network. 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 (BSS), an 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, and the base station is not limited to a specific technical term as long as it can achieve a similar technical effect. It should be noted that in the embodiment of the present application, a base station in an NR system is merely taken as an example, and the specific type of the base station is not limited.

[0044] The first network node 13 may be an intelligent surface device or a repeater device. The intelligent surface device may include, but is not limited to, an intelligent reflective surface (IRS) device, a massive intelligent surface (LIS), a smart reflectarray (SRA) and a deployable reflectarray (RRA). Each reflecting element of the intelligent surface device can independently induce a change in the amplitude and / or phase and / or polarization of the incident signal, that is, to rearrange the radio propagation environment by controlling the reflection. In addition, the intelligent surface device does not use a transmit RF chain and only operates at a short distance, so that it can be deployed densely. Compared with traditional backscatter communication (e.g., RFID), the IRS is a passive reflecting device that does not transmit information of its own, but is only used to facilitate existing communication links. Compared with traditional massive MIMO technology, the IRS is a passive array and massive MIMO is an active array. The IRS is generally used as a reflectarray, and massive MIMO is generally used as a transmit array.

[0045] The main types of IRS reflector units are A tunable resonator, B guided wave control method, and C circular polarization steering technology. A tunable resonator is a type in which a variable capacitor is built into the resonator to change the frequency-agile patch resonator frequency, thereby generating a phase shift. In B guided wave control method, the arriving spatial wave is coupled to the guided wave by the antenna, and then the guided wave is phase shifted and re-radiated to form an antenna phase shifter. C circular polarization steering technology is designed using the reflection law of electromagnetic waves.

[0046] Reflectarrays / intelligent surfaces can be broadly classified into the following two types based on whether or not they can be dynamically controlled.

[0047] 1) Static Reflectarrays / Intelligent Surfaces The structure and function of the reflectarray can be fixed, and for an incident wave at a specific angle, the metasurface units will fixedly change the characteristics of the incident wave, such as the amplitude, phase, polarization manner, etc., to obtain a corresponding reflected wave.

[0048] 2) Dynamic Reflect Array / Intelligent Surfaces The structure and function of the reflectarray are controllable, and for a certain angle of incident wave, the amplitude, phase, polarization manner and other characteristics of the incident wave can be changed differently through programmable control to obtain the corresponding reflected wave. To realize the programmable control over the reflective metasurface, it is necessary to introduce a switching element (e.g., diode, RF-MEMS switch, etc.) into the reflecting unit.

[0049] PIN diodes are currently a popular choice for controlling reconfigurable metasurfaces. PIN diodes have a wide range of high-frequency impedance and low distortion, and are widely used in the field of microwave radio frequencies. Due to the switch element in the reflective unit, the reflective unit can have multiple different states, and the switching between different states can be realized by controlling the on and off of the switch element. In both cases, the structure and performance of the corresponding reflective unit will change significantly. That is, the reflective units in different states have different control modes for the amplitude, phase, polarization, and other properties of the incident wave.

[0050] Hereinafter, the technical solutions provided in the embodiments of the present application will be described in detail in specific embodiments and their application scenarios with reference to the drawings.

[0051] 2 shows a schematic diagram of a terminal information acquisition method according to an embodiment of the present application, and the method 200 may be performed by a first network node. In other words, the method may be performed by software or hardware installed in the first network node, and the first network node may be an intelligent surface-type device or a relay-type device. As shown in FIG. 2, the method may include the following steps:

[0052] At S210, a first signal transmitted from a terminal is received.

[0053] In an embodiment of the present application, the terminal can transmit a first signal in a specific beam. In one possible implementation, the terminal can transmit the first signal in a manner of time domain repetition, i.e., the terminal can repeatedly transmit the first signal in the time domain. Therefore, in this possible implementation, S210 may include receiving the first signal transmitted by the terminal in the manner of time domain repetition. In this possible implementation, the terminal repeatedly transmits the first signal in the time domain, thereby increasing the success rate of the first network node receiving the first signal.

[0054] In the above possible implementation, in order to further guarantee the success rate of the first network node receiving the first signal, in one possible implementation, the beams used for transmitting the first signal in the manner of time domain repetition are different, i.e., the terminal transmits the first signal in different beams at different times, thereby avoiding the problem that the first network node fails to receive the first signal due to reasons such as blocking of a certain beam. In addition, by the terminal transmitting the first signal in different beams at different times, the first network node can obtain more beam information of the terminal. Of course, this is not limited thereto, and the beams used for transmitting the first signal in the manner of time domain repetition may be the same, i.e., the terminal may transmit the first signal in the same beam at different times.

[0055] In one possible implementation, since the beam used by the terminal to transmit the first signal is unknown to the first network node, the first network node can receive the first signal transmitted from the terminal in a manner of receive beam polling in S210. For example, assuming that the first network node has four receive beams, the first network node can receive the first signal in a polling manner by first receiving the first receive beam, then receiving the second receive beam, receiving the third receive beam, receiving the fourth receive beam, and then receiving the first receive beam again.

[0056] In one possible implementation, the first signal may be carried in a predetermined signal, for example, in one of a Sounding Reference Signal (SRS), a Demodulation Reference Signal (DMRS), a Random Access Channel (RACH) sequence such as a Random Access Preamble, and a dedicated sequence for the first signal. In this possible implementation, the first network node may receive the first signal in a manner of polling a receiving beam according to time.

[0057] In one possible implementation, the format of the first signal may be configured by the network side, or may be preset, for example, specified by a protocol. For example, the fact that the first signal is carried by any one of the above signals, i.e., information regarding the sequence of the first signal, may be configured in advance by the network side. For example, the sequence format of the first signal and the method of associating the terminal identifier, etc. may be configured in advance by the network side or specified in advance by a protocol. Of course, this is not limited, and for example, the time-frequency resource for transmitting the first signal may be configured by the network side or specified in a protocol without limiting the specific format of the first signal.

[0058] In one possible implementation, in S210, when receiving the first signal, the first network node can obtain the first signal in a manner of sequence detection. For example, when the sequence format of the first signal and the association manner of the terminal identifier are configured by the network side, the first network node can identify the terminal transmitting the first signal in a manner of sequence detection. And / or, the first network node can also grasp the first signal in a manner of energy detection. For example, the terminal can grasp the fourth signal by detecting whether the energy on a specific receiving beam is equal to or greater than a predetermined threshold.

[0059] In one possible implementation, the first network node can complete the reception of said first signal by its first module (ie a module having a receiving function).

[0060] At S212, first information of the terminal is estimated based on the first signal, and the first information includes at least one of location information of the terminal, direction information of the terminal, receiving beam information corresponding to the terminal, and transmitting beam information corresponding to the terminal.

[0061] For example, when the sequence format of the first signal and the method of associating the terminal identifier are configured by the network side, the first network node can identify the terminal transmitting the first signal by the method of sequence detection. Based on the receiving beam used to receive the first signal, the first network node identifies the receiving beam signal corresponding to the terminal and the transmitting beam signal corresponding to the terminal. Based on information such as the strength of the received first signal, the first network node estimates information such as the direction of the terminal relative to the network side device.

[0062] If the terminals are within the coverage of the intelligent surface device or repeater but beyond the coverage of the base station associated with the intelligent surface device or repeater, the method may further include, in one possible implementation, after S212, sending a second signal to a second network node, the second signal carrying the content of all or part of the first information, and the second network node being a base station node associated with the first network node, so that the base station can discover and serve these terminals. For example, the second network node may be the network side device 12 in FIG. 1.

[0063] In one possible implementation, the second signal further includes at least one of the following (1) to (3): (1) Information regarding the identifier of the terminal. For example, information about the sequence of SRS, DMRS, RACH or other signals that helps the base station identify the terminal, such as a scrambling sequence index, etc. Another example may be sequence information received on different receive beams. (2) The index of the first signal received. (3) Information regarding the strength of the first signal corresponding to each said index.

[0064] The index is for identifying the received first signal, and the strength information indicates strength information of the first signal corresponding to the index, e.g., energy and / or power information received on different receive beams (corresponding to different indices).

[0065] In one possible implementation, the first network node is capable of reporting said second signal by means of its third module (ie a module having a transmitting function).

[0066] In one possible implementation, the step of the first network node reporting the second signal may further include a step of the first network node conveying third information to a second network node (e.g., gNB) by control information. The third information may indicate resource information for beam management required for the UE, and the resources for beam management may include at least CSI-RS resources and / or SRS resources. The resource information includes at least a number of single-port CSI-RS / SRS resources or a total number of required ports.

[0067] The third information may be determined based on a quality of a first signal of the UE received by the first network node.

[0068] In one possible implementation, after the step of transmitting a second signal to a second network node, the method may further include the steps of receiving a third signal transmitted from the second network node and adjusting a transmission mode of the first network node based on the third signal. In this possible implementation, the second network node can determine whether the transmission mode of the first network node needs to be adjusted and how to adjust the transmission mode of the first network node based on the received second signal, and transmit a corresponding third signal to the first network node, thereby adjusting the transmission mode of the first network node to improve the quality of signal transmission and reception by the first network node.

[0069] In one possible implementation, the adjustment of the transmission mode may include adjustment of at least one of the beam, Transmission Configuration Index (TCI) information, and Quasi-Colocation (QCL) information, which may improve the quality of signal transmission and / or signal reception by the first network node.

[0070] The first network node may be an intelligent surface device or a non-base station device such as a repeater. If the first network node is an intelligent surface device, the intelligent surface device optionally includes a first module having a signal receiving function and a second module having a function of adjusting the phase, amplitude or polarization mode of an external signal. For example, the first module may not support complex functions such as channel decoding, but only support the function of energy detection or sequence reception. Optionally, the intelligent surface device may further include a third module supporting transmitting its own information to a terminal or a base station.

[0071] Therefore, in the above possible implementation form, the step of adjusting a transmission mode of the first network node based on the third signal may include a step of adjusting a state of a reflecting unit and / or a refraction unit in the first network node based on the third signal.

[0072] That is, the transmission mode of the first network node can be realized by adjusting the switch pattern of the switch element of the reflecting or refracting unit in the first network node device. The transmission mode is related to the beam direction, and the reflecting unit or the refracting unit can have multiple different states according to the switch element, and the switching of different states is realized by controlling the on / off of the switch element, and the direction, phase, amplitude and / or polarization manner of the reflected wave or the refracted wave corresponding to the different states are different. For example, if 1 represents the switch element on and 0 represents the switch element off, the pattern of the switch element of the 100×100 radiation unit is a 01-bit matrix with 100×100 dimensions.

[0073] When the first network node is a repeater, the repeater may be any of various repeaters such as direct forwarding, transparent forwarding, amplifying and forwarding, or demodulating the signal before transmitting, and the embodiments of the present application are not limited thereto.

[0074] Optionally, the repeater comprises a first module for receiving a signal and a second module for forwarding a signal, and optionally, the repeater further comprises a third module for supporting transmitting its own information to a terminal or a base station.

[0075] A base station associated with the first network node may have the following features: the base station controls the transmission mode (e.g. beam / TCI / QCL) of the first network node by sending signaling to the first network node, or the transmission and reception signals of the base station are forwarded via the first network node.

[0076] In one possible implementation, the first network node may directly adjust a transmission beam and / or a reception beam associated with the terminal based on the estimated first information of the terminal. Thus, in this possible implementation, after S212, the method may further include a step of adjusting a transmission beam and / or a reception beam associated with the terminal based on the first information. For example, the first network node may adjust its transmission beam and / or reception beam based on the estimated terminal direction information to improve the quality of the signal transmitted between the first network node and the terminal. For example, the first network node may achieve this by adjusting its second module.

[0077] According to the above technical solution provided in the embodiments of the present application, after the first network node (including an intelligent surface-type device or a relay-type device) receives a first signal transmitted from a terminal, it estimates first information of the terminal based on the first signal, thereby obtaining the terminal's location information, direction information, receiving beam information or transmitting beam information, and further obtaining information about the terminal based on the first information, thereby solving the problem of the intelligent surface device or relay-type device not being able to grasp the information about the terminal.

[0078] It should be noted that in the embodiment of the present application, the first network node may forward the acquired first information to its associated base station, and the base station may know the terminal and communicate with the terminal based on the report of the first network node. The base station may also transmit a third signal to the first network node based on the acquired information to adjust a transmission mode of the first network node to improve communication quality. Alternatively, the first network node may adjust a transmission beam and / or a reception beam associated with the terminal based on the estimated first information to improve the quality of signal transmission to and from the terminal.

[0079] 3 shows another procedure diagram of a terminal information acquisition method according to an embodiment of the present application, where the method 300 may be performed by a terminal, a first network node and a base station. The base station is the second network node in the above method 200. In other words, the method may be performed by software or hardware installed in the terminal, the first network node and the base station. As shown in FIG. 3, the method may include the following steps:

[0080] At S310, a terminal (UE) transmits a first signal to a first network node.

[0081] Alternatively, the UE may transmit the first signal in a time domain repetitive manner, for example, transmitting the first signal at different times on different or the same beams.

[0082] At S312, the first network node receives a first signal transmitted from the UE.

[0083] The first signal may be carried in an SRS, a DMRS, a RACH sequence, or another sequence (eg, a dedicated sequence, etc.).

[0084] The first network node can receive the first signal in a manner of polling the receiving beam according to time, and the format of the first signal, such as information about the sequence, can be arranged by the network side or specified in a protocol. For example, the protocol can specify the association manner between the sequence format and the UE ID, or can specify only the time-frequency resource of the first signal transmission without limiting the specific format of the signal.

[0085] Optionally, the first network node can complete the above-mentioned receiving by a first module (a module having a signal receiving function).

[0086] Optionally, the first network node receives the first signal in a manner of receive beam polling.

[0087] S312 is similar to S210 in method 200, and details thereof can be found in the description of S210 in method 200 above.

[0088] At S314, the first network node estimates first information of the UE based on the received first signal of the UE, where the first information includes, but is not limited to, one or more of the following: location information of the UE, direction information, receiving beam and / or transmitting beam of the corresponding first network node.

[0089] Optionally, the first network node may obtain the first signal transmitted from the UE by sequence detection.

[0090] Optionally, the first network node may learn of the first signal transmitted from the UE by energy detection.

[0091] Since S314 is similar to S212 in the above method 200, other details not described may be referred to the description of S212 in the above method 200.

[0092] After the first network node identifies the first signal of the UE, it can adjust its transmitting beam and / or receiving beam associated with the UE to improve the signal transmission quality between the first network node and the UE.

[0093] Optionally, the first network node may also report the second signal to the base station to assist the terminal in completing transmission / reception to the base station associated with the first network node. Therefore, after S314, S316 and S318 may be further included.

[0094] At S316, the first network node reports the second signal to a base station associated with the first network node by a third module (a module having a signal transmission function).

[0095] The second signal may include receiving / transmitting beam information or position information or direction information of the first network node corresponding to the UE estimated by the first network node.

[0096] Optionally, the second signal may further include information about the UE ID, such as information about the sequence of SRS, DMRS, RACH or other signals that helps the base station identify the UE, such as a scrambling sequence index, or sequence information received on different receive beams.

[0097] Optionally, the second signal may further include energy / power information of the first signal received by the first network node, for example energy / power information received on different receiving beams.

[0098] At S318, the base station sends signaling (ie, the third signal) to the first network node to adjust the transmission mode of the first network node, thereby adjusting the transmission and / or reception behavior of the first network node.

[0099] For details of the adjustment method, please refer to the relevant description of the method 200 above, and detailed description will be omitted here.

[0100] In the above method provided in the embodiment of the present application, the first network node receives a signal transmitted from the UE, identifies the UE's location information, direction information, receiving beam information or transmitting beam information, etc., and reports the information to the base station, so that the base station can identify the beam direction between the first network node and the UE based on the information, and the base station can discover the UE and provide service to the UE, thereby solving the communication problem between the UE and the base station corresponding to the first network node.

[0101] 4 shows a schematic diagram of a signal receiving method provided in an embodiment of the present application, and the method 400 may be performed by a terminal. In other words, the method may be performed by software or hardware installed in the terminal. As shown in FIG. 4, the method may include the following steps:

[0102] At S410, a fourth signal transmitted from a first network node is received, the first network node being an intelligent surface type device or a relay type device.

[0103] In one possible implementation, second information is carried in the fourth signal, and the second information may include at least one of the following (1) to (5).

[0104] (1) Synchronization information. By means of this information, synchronization between the terminal and the first network node can be achieved.

[0105] (2) Identifier information of the first network node. The information enables the terminal to know the first network node that transmits the fourth signal.

[0106] (3) Beam information of the first network node. This information enables the terminal to grasp the available beam information of the first network node and determine the available beam information when transmitting a signal to the first network node.

[0107] (4) A time window for transmitting the first network node. This information allows the terminal to know the time window during which the first network node performs forwarding, i.e. the first network node forwards signals within this time window, the terminal can transmit signals within this time window for transmission to the base station that do not require processing by the first network node, and the first network node transparently transmits signals received within this time window to the base station.

[0108] (5) Time information related to beam information of the first network node. According to the information, the terminal can know available beam information of the first network node and time information corresponding to different beams, for example, the time corresponding to beam 1 is the first downlink slot and the second uplink slot in one TDD cycle (assuming two downlink slots and two uplink slots), and the time corresponding to beam 2 is the second downlink slot and the first uplink slot in one TDD cycle, and the terminal uses this to determine available beam information and slots when transmitting signals to the first network node, and determines available beam information and slots when receiving signals from the first network node.

[0109] For example, the first network node may transmit the fourth signal to the UE in the form of beam scanning or broadcast.

[0110] Optionally, the first network node transmits a fourth signal by a third module (a module having a signal transmitting function).

[0111] In one possible implementation, S410 may include at least one of the following (1) to (3).

[0112] (1) The fourth signal is received using the receive beam polling method. That is, the terminal detects the presence or absence of the fourth signal transmission in time by a receive beam polling method, and receives the transmitted fourth signal.

[0113] (2) Obtaining the fourth signal by sequence detection. Similar to the above method 200, the UE can obtain the fourth signal through sequence detection. For example, the terminal can detect the sequence transmitted by the first network node, and if the sequence format matches a predetermined sequence format, the fourth signal is obtained.

[0114] (3) The fourth signal is identified by energy detection. For example, the terminal can recognize the fourth signal by detecting that the energy on a particular receive beam is above a predetermined threshold.

[0115] At S412, a fifth signal is transmitted to the first network node or a second network node, the fifth signal carrying some or all of the information relating to the fourth signal, and the second network node is a base station-type device associated with the first network node.

[0116] In one possible implementation form, some or all of the information about the fourth signal carried in the fifth signal includes, but is not limited to, at least one of (1) to (3).

[0117] (1) At least one target receive beam information. The at least one target receiving beam information is information about a receiving beam having the strongest signal strength estimated based on the fourth signal.

[0118] (2) At least one target transmit beam information. The at least one target transmission beam information is information about a transmission beam corresponding to the reception beam having the strongest signal strength.

[0119] For example, if a terminal receives a fourth signal through each of receiving beam 1 and receiving beam 2, and the signal strength of the fourth signal received through receiving beam 1 is stronger than that of the fourth signal received through receiving beam 2, the target receiving beam information is information about receiving beam 1, and the target transmitting beam information is information about a transmitting beam (e.g., transmitting beam 1) corresponding to receiving beam 1.

[0120] The information about the receive beam may be a synchronization signal block (SSB) index, or the receive strength of the strongest SSB, etc.

[0121] (3) Information regarding the identifier of the terminal. For example, when the association relationship between the sequence format and the terminal identifier is configured by the network side, the information on the terminal identifier may be an identifier (eg, an index) of the sequence format corresponding to the terminal identifier.

[0122] In one possible implementation, transmitting the fifth signal at S412 may include transmitting the fifth signal in the target slot.

[0123] In one possible implementation, the target slot may be a slot within a forwarding time window of the first network node, in which the fifth signal is a signal to be transmitted to the base station, which does not need to be processed in the first network node, but only forwarded via the first network node.

[0124] Alternatively, in another possible implementation, the target slot may be a slot outside the forwarding time window of the first network node. In this possible implementation, the fifth signal is a signal to be transmitted to the first network node (for example, the first signal in the above-mentioned method 200 and method 300), the terminal can transmit the fifth signal in the transmission manner of the first signal described in the above-mentioned method 200 and method 300, and after receiving the fifth signal, the first network node can process it correspondingly as described in the above-mentioned method 200 and method 300, and the details can be referred to the description of the method 200 and method 300, and the detailed description is omitted here.

[0125] In one possible implementation, in order to ensure the quality of the fifth signal reception by the first network node, the step of transmitting the fifth signal in S412 may include the step of transmitting the fifth signal in a target transmission beam, the target transmission beam corresponding to a target reception beam, and the target reception beam being a beam used to receive the fourth signal having the strongest signal strength. For example, when the terminal receives the fourth signal, if the signal strength of the fourth signal received in reception beam 2 is the strongest, the terminal can transmit the fifth signal in S412 in a transmission beam corresponding to reception beam 2 so as to ensure the strength of the fifth signal received by the first network node.

[0126] In the above technical solution provided in the embodiments of the present application, the first network node transmits a fourth signal to the terminal, the terminal receives the signal, determines information related to the fourth signal, and transmits some or all of the information of the fourth signal to a second network node associated with the first network node, so that the second network node (i.e., a base station) can discover the terminal and provide services to the terminal.

[0127] Figure 5 shows another procedure diagram of a signal receiving method in an embodiment of the present application, as shown in Figure 5, the method 500 may be performed by a terminal (UE), a first network node and a base station, the base station being the second network node in the above method 400. In other words, the method may be performed by software or hardware installed in the terminal, the first network node and the base station. As shown in Figure 5, the method may include the following steps:

[0128] At S510, the first network node transmits a fourth signal to the terminal in the form of beam scanning or broadcasting, and the information carried in the fourth signal includes at least one of information such as synchronization information, ID information of the first network node, beam information, and a time window of the first network node transmission.

[0129] Optionally, the first network node is capable of transmitting a fourth signal by its third module.

[0130] Optionally, the information carried in the fourth signal includes time information and beam information related to the time information.

[0131] At S512, the UE receives a fourth signal.

[0132] Alternatively, the UE receives the fourth signal in the manner of receive beam polling.

[0133] Alternatively, the UE may obtain the fourth signal by sequence detection.

[0134] Alternatively, the UE may learn of the fourth signal by energy detection.

[0135] At S514, after obtaining the information carried in the fourth signal, the UE transmits a fifth signal according to the rules defined in the protocol.

[0136] The fifth signal may carry at least one of the strongest receiving beam information / transmitting beam information (e.g., the strongest SSB index and / or SSB receiving strength, etc.) estimated by the UE based on the fourth signal, information regarding the UE ID, etc.

[0137] Alternatively, the UE may transmit a fifth signal in a specific slot, which may be in the following two implementations:

[0138] In scheme 1, the fifth signal is transmitted to the base station.

[0139] The slot may be a slot within a first network node forwarding time window.

[0140] As shown in FIG. 5, after receiving the fifth signal, the first network node executes S516 and forwards the fifth signal, and a base station associated with the first network node receives the fifth signal sent from the UE.

[0141] At S518, after receiving the fifth signal, the base station sends control signaling to the first network node to control the beam direction of the first network node, thereby communicating with the UE via the first network node.

[0142] For scheme 2, the fifth signal is transmitted to the first network node.

[0143] The slot may be a slot outside the transmission time window, and the first network node may receive a fifth signal from the UE in the slot, and then perform the processing process after receiving the first signal in the methods 200 and 300.

[0144] Optionally, the UE transmits a fifth signal to the first network node on a transmit beam that corresponds to the receive beam used to receive the strongest fourth signal.
