[0015] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the present disclosure will be described in more detail below in conjunction with drawings and embodiments. It should be understood that the specific embodiments described herein are only used to describe the present disclosure, and are not used to limit the present disclosure.

[0016] In the description of the embodiments of the present disclosure, when there are statements such as "first", "second", etc., it should be understood that "first", "second", etc. are used only for the purpose of distinguishing technical features, and are not to be understood as indicating relative importance, implying a plurality of the indicated technical features, or implying a priority relationship of the indicated technical features. "At least one" refers to one or more, and "multiple" refers to two or more. "And / or" describes an associated relationship between related objects and indicates that three relationships can exist, for example, A and / or B indicates that A may exist alone, A and B may exist simultaneously, and B may exist alone. Here, A and B may be singular or plural. The character " / " generally represents an "or" relationship between related objects. "At least one of" and similar expressions refer to any group of items, including any group of singular or multiple items. For example, at least one of a, b, and c is a, or b, or c, or a and b, or a and c, or b and c, or a, b, and c, where a, b, and c may be singular or plural.

[0017] Furthermore, the technical features according to the various embodiments of the present disclosure described below may be combined if they do not conflict with each other.

[0018] One of the main problems in high frequency communication is that as the transmission distance increases, the signal energy attenuates rapidly, which reduces the signal transmission distance and further affects the signal coverage range of the cell. In order to increase the signal coverage range of the cell, in the prior art, the cell coverage can be increased by adding a Reconfigurable Intelligent Surface (RIS) or a Smart Repeater between the network equipment and the terminal.

[0019] As shown in FIG. 1, it is a schematic diagram of a communication system applied to an embodiment of the present disclosure. The communication system shown in FIG. 1 includes a network device 10, a signal conditioning device 20, and a plurality of terminals (31, 41, 42). Here, the terminals may be divided into two types, a first type and a second type. The first type of terminal is within the direct coverage range of the network device and directly accesses the network device, such as the terminal 31 in FIG. 1. The second type of terminal is outside the direct coverage range of the network device and accesses the network device through a signal conditioning device, such as the terminals 41 and 42 in FIG. 1. That is, for information between the network device 10 and the terminals 41 and 42, relay via the signal conditioning device 20 is required to reach. The signal conditioning device 20 here may be regarded as a RIS or a Smart Repeater.

[0020] It can be understood that the network equipment according to the embodiment of the present disclosure may be a node in a radio access network, may be called a base station, or may be called a Radio Access Network (RAN) node (or device). For example, the network equipment may include an evolved base station (NodeB or eNB or e-NodeB, evolved Node B) in a Long Term Evolution (LTE) system or an LTE-Advanced (LTE-A) system, such as a traditional macro base station eNB or a micro base station eNB in ​​a heterogeneous network scene. Alternatively, the network equipment may include a Next Generation Node B (gNB) in a 5th Generation (5G) New Radio (NR) system. Alternatively, the network equipment may further include a Transmission Reception Point (TRP), a home base station (e.g., Home evolved NodeB or Home Node B, HNB), a Base Band Unit (BBU), a Base Band Pool (BBU pool), a Wi-Fi Access Point (AP), etc. Alternatively, the network equipment may further include a Centralized Unit (CU) and a Distributed Unit (DU) in a Cloud Radio Access Network (Cloud RAN) system. The network equipment may include a base station in a Non-Terrestrial Network (NTN) that can be mounted on a high altitude platform or a satellite.In NTN, the network equipment may be used as a layer 1 (L1) relay, or as a base station, or as a DU, or as an integrated access and backhaul (IAB) node. Alternatively, the network equipment may be an equipment implementing a base station function in IoT, such as an equipment implementing a base station function in V2X (Vehicle-to-everything), D2D (Device to Device), or M2M (Machine to Machine), and is not limited thereto in the embodiments of the present disclosure.

[0021] It should be understood that the terminal according to the embodiment of the present disclosure may refer to a user equipment, an access terminal, a user unit, a user station, a mobile station, a mobile device, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user equipment. The terminal may also be a mobile phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capability, a computing device, other processing devices connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5G network, or a terminal device in a future evolving communication network, and is not limited thereto in the embodiment of the present disclosure.

[0022] It is understood that the reconfigurable intelligent surface RIS according to an embodiment of the present disclosure is an artificial electromagnetic surface structure with programmable electromagnetic characteristics. The panel of the RIS contains a large number of electromagnetic units arranged in a matrix, and the electromagnetic characteristics of the electromagnetic units can be dynamically adjusted through a control circuit, thereby realizing the intelligent reconfiguration of the propagation characteristics of wireless signals in three-dimensional space, and breaking through the limitations of traditional passive adaptation of wireless environments.

[0023] It should be understood that the smart repeater according to the embodiment of the present disclosure may be regarded as a signal relaying device deployed between a network node and a terminal device to improve link performance. In the case of downlink, the smart repeater receives information from the network node, enhances and amplifies the information, and then transmits the information to the terminal device. The same is true for the uplink.

[0024] For convenience, in some descriptions of the embodiments of the present disclosure, "base station" may be used to refer to network equipment, "RIS" or "Smart Repeater" may be used to represent signal conditioning equipment, and "UE" or "user" may be used to refer to a terminal.

[0025] In order to easily understand the technical solution of the present disclosure, a random access process for establishing a connection between a terminal and a network device will be briefly described.

[0026] The random access process refers to the process from when a user attempts to access a network by sending a random access preamble to when a basic signaling connection with the network is established. Random access is an important step in a mobile communication system and is also the final step in establishing a communication link between a terminal device and a network. Through random access, the terminal device can have information interaction with a network device. Depending on whether the user exclusively occupies the preamble resource, the user's random access method may be classified into contention-based random access and contention-free random access.

[0027] The contention-based random access process mainly includes the following four steps: In the first step, the terminal randomly selects a preamble from a preamble resource pool, and sends a random access request to a network device through a first message Msg1, where Msg1 includes a random access preamble. In the second step, the network device sends a random access response (RAR) to the terminal through a second message Msg2, where Msg2 includes information such as a random access preamble identifier, a Cell-Radio Network Temporary Identifier (C-RNTI), and time-frequency resources allocated for the terminal's next uplink transmission. In the third step, the terminal sends a Radio Resource Control (RRC) connection request to the network device through a third message Msg3, where Msg3 includes information such as a user terminal identifier, an RRC link request, where the user terminal identifier is unique to the user and is used to resolve the collision. In the fourth step, the network device sends a fourth message Msg4 to the terminal (this process is a contention resolution process), and Msg4 includes the user terminal identifier that won the contention resolution. After the user detects its identifier, it upgrades the temporary C-RNTI to C-RNTI, sends an ACK signal to the base station, completes the random access process, and waits for the base station to schedule. If not, the user starts a new random access process after a delay.

[0028] The non-contention-based random access process mainly includes two steps. In the first step, the terminal sends the assigned random access preamble to the network equipment through an A message MsgA (random access request). In the second step, the network equipment detects the assigned random access preamble and then sends information such as timing advancement, uplink resource allocation, etc. to the terminal through a B message MsgB (random access response, RAR (Random Access Response)). After receiving the random access response, the user considers that uplink synchronization is completed and waits for further scheduling of the base station. Therefore, the non-contention-based random access process only includes two steps, step 1 is to send a preamble sequence, and step 2 is to send a random access response.

[0029] It is understood that when a terminal accesses a network device via a RIS / Smart Repeater, the information exchange between the terminal and the network device in the above-mentioned random access process can only be realized through the RIS / Smart Repeater relay.

[0030] For network equipment, if it can identify whether the access method of the terminal is direct access or relay access via RIS / Smart Repeater in the random access process, a personalized strategy can be formulated and it is favorable for the geographical deployment of RIS / Smart Repeater. In the current protocol framework, the location of the terminal can be roughly estimated by distinguishing the accessed SSB beam, but the accuracy is low, and since the beam coverage of FR2 is relatively large, there may be terminals that access directly and terminals that access relay via RIS / Smart Repeater under the same receiving beam, so it is difficult to accurately identify the type of terminal in the access stage.

[0031] In order to solve the above technical problems, embodiments of the present disclosure provide a method for controlling a random access process, a network device, a signal conditioning device, a terminal, a computer-readable storage medium, and a computer program product to realize identification of a terminal type at an access stage.

[0032] As shown in Figure 2, it is a flowchart of a control method for a random access process according to an embodiment of the present disclosure. This method is applied to the network device side and includes the following steps S110 to S130. Each of steps S110 to S130 will be described in turn below.

[0033] In step S110, issue first configuration information to the terminal, which is used to instruct the terminal to repeatedly transmit multiple uplink signals after receiving the random access response message.

[0034] In an embodiment of the present disclosure, the network device issues first configuration information to a terminal, for the purpose of the terminal initiating a random access request to the network device, and repeatedly transmitting multiple uplink signals to the network device based on the first configuration information after receiving a random access response from the network device.

[0035] As an example, when a terminal initiates a contention-based random access request to a network device, the terminal repeatedly transmitting multiple uplink signals to the network device may be repeatedly transmitting a third message (Msg3) in multiple random access processes to the network device.

[0036] As another example, the terminal repeatedly transmits a plurality of uplink signals to the network device may be repeatedly transmitting a plurality of physical uplink shared channels (PUSCHs) to the network device. After receiving uplink resources allocated by the network device, the terminal may repeatedly transmit PUSCHs to the network device based on the allocated uplink resources.

[0037] It should be understood that the uplink signal repeatedly transmitted by the terminal may be other types of signals, but the embodiments of the present disclosure are not limited thereto.

[0038] The first configuration information in the embodiment of the present disclosure includes at least one of a time domain start position of the repeated transmission, a time domain interval of the repeated transmission, and a number of the repeated transmission signals. Here, the time domain start position of the repeated transmission indicates a time domain position of a first uplink signal among the multiple uplink signals of the repeated transmission, specifically, indicates one offset interval in units of a time slot or a symbol, that is, the repeated transmission of the uplink signal may start after the above offset interval has elapsed from the reception time of the random access response message. The time domain interval of the repeated transmission indicates a transmission time domain interval of the repeatedly transmitted uplink signal, that is, indicates a time domain interval between signals repeatedly transmitted twice, in units of a time slot, a symbol, etc. The number of the repeated transmission signals indicates the number of repeated transmissions of the repeatedly transmitted uplink signal, for example, when the transmission is repeated four times, the number of the repeated transmission signals is four. Of course, the first configuration information may include more or less information than the above. For example, the first configuration information may not indicate a time domain start position of the repeated transmission, and the terminal may use a default offset interval to determine the time domain start position of the repeated transmission. The first configuration information may not specify a time domain interval for repeated transmission, and the terminal may use a default time domain interval to perform repeated transmission. Also, the first configuration information may not specify the number of repeated transmission signals, and the terminal may use the default number of repeated transmission signals to perform repeated transmission.

[0039] Illustratively, the network device may issue the first configuration information to the terminal in several manners:

[0040] In the first manner, a network device transmits Random Access Channel (RACH) configuration information to a terminal, and the RACH configuration information includes an information element carrying first configuration information, where the RACH configuration information can be RACH-Config Common information, RACH-Config Dedicated signaling, or RACH-Config Generic signaling.

[0041] Take the case where RACH-Config Common information is RACH configuration information as an example, so that the first configuration information is carried in the RACH-Config Common information, a field related to the first configuration information may be added to the information element (IE) of the RACH-Config Common information. As shown in Figure 3, which is a schematic diagram of the format of RACH-Config Common information, where the field related to the first configuration information includes K2-offset-repetition and repetition-Number-Msg3. Here, K2-offset-repetition means the time domain interval of repeated transmission, and repetition-Number-Msg3 means the number of repeated transmission signals.

[0042] In the second manner, the network device sends to the terminal via a random access response message, and the first configuration information is carried in the random access response message.

[0043] It is understood that the network device may issue the first configuration information to the terminal through a RAR message in the random access process, i.e., carry the first configuration information in the RAR message in the random access process. The RAR message here may specifically be a second message in the random access process (including a contention-based random access manner or a non-contention-based random access manner). Specifically, the first configuration information may include a field related to the first configuration information, such as: K2 +j (time domain start position of repetitive transmission), K2-offset-repetition (time domain interval of repetitive transmission), and repetition-Number-Msg3 (number of repetitive transmission signals), etc. may be added to the RAR message.

[0044] In step S120, second configuration information is issued to the signal coordinating device, which is used to instruct the signal coordinating device to relay the first uplink signal and the second uplink signal in a different configuration manner.

[0045] In an embodiment of the present disclosure, the terminal initiates a random access request to a network device, and the network device sends a random access response to the terminal. After receiving the random access response, the terminal repeatedly sends a plurality of uplink signals to the network device according to the first configuration information preset.

[0046] The multiple uplink signals repeatedly transmitted by the terminal include a first uplink signal and a second uplink signal. Specifically, the first uplink signal and the second uplink signal are different signals among the multiple uplink signals repeatedly transmitted by the terminal. The first uplink signal may include one or more signals, and the second uplink signal may include one or more signals.

[0047] In one example, the first uplink signal represents the i-th uplink signal among the multiple uplink signals repeatedly transmitted by the terminal, where i is an odd number. The second uplink signal represents the j-th uplink signal among the multiple uplink signals repeatedly transmitted by the terminal, where j is an even number. For example, after receiving a random access response from the network device, the terminal repeatedly transmits four uplink signals, of which the first and third signals belong to the first uplink signal, and the second and fourth signals belong to the second uplink signal.

[0048] The first uplink signal and the second uplink signal may represent one or more specific signals among a plurality of uplink signals repeatedly transmitted by the terminal. For example, after receiving a random access response from the network device, the terminal repeatedly transmits four uplink signals, among which the first uplink signal identifies the first signal and the second signal, and the second uplink signal identifies the third signal and the fourth signal.

[0049] In the embodiment of the present disclosure, the network device issues the second configuration information to the signal conditioning device, with the purpose of relaying the first and second uplink signals of the uplink signals in different manners after the signal conditioning device receives the multiple uplink signals of the repeated transmission from the terminal. Generally, signals relayed in different manners have a large difference on the network device side. Meanwhile, the multiple uplink signals that the terminal repeatedly transmits directly to the network device are not specially processed, so there is no large difference on the network device side. In this way, the network device can determine whether the uplink signals are relayed via the signal conditioning device or directly transmitted by the terminal based on whether there is a large difference between the received multiple uplink signals of the repeated transmission.

[0050] Exemplarily, the second configuration information includes at least one of a time domain start position of the repeated transmission, a time domain interval of the repeated transmission, the number of repeated transmission signals, codebook modification information, phase modification information, and relay stop instruction information.

[0051] Here, the time domain start position of the repeated transmission indicates the time domain position of a first uplink signal among multiple uplink signals repeatedly transmitted by the terminal, and the signal adjustment device may determine the start position at which the uplink signal is received based on the time domain start position.

[0052] The time domain interval of the repeated transmission indicates the time domain interval of the multiple uplink signals that are repeatedly transmitted, and the signal coordinating device may receive the uplink signals that are repeatedly transmitted by the terminal based on the time domain interval.

[0053] The number of repeated transmission signals indicates the number of uplink signals repeatedly transmitted by the terminal, and the signal adjustment device may receive a corresponding number of uplink signals based on the number of repeated transmission signals.

[0054] The codebook change information is sent to the signal conditioning device. Change the first codebook, specifically may be a codebook index, thereby allowing the signal conditioning device to obtain the second codebook according to the codebook index. It is understood that the second codebook is a codebook different from the first codebook, and the first codebook is the codebook that the signal conditioning device originally uses to relay the current terminal signal.

[0055] The phase change information is used to derive the third codebook by causing the signal conditioner to change the phase of the first codebook.

[0056] The relay stop instruction information is used to cause the signal coordinator to relay a part of the uplink signal repeatedly transmitted by the terminal using a relay stop strategy.

[0057] It should be understood that the second configuration information may include one or more of the time domain start position of the repeated transmission, the time domain interval of the repeated transmission, the number of repeated transmission signals, codebook modification information, phase modification information, and relay stop instruction information, and the specific content of the second configuration information is not limited in the embodiments of the present disclosure.

[0058] Illustratively, the signal conditioning device relaying the first uplink signal and the second uplink signal in different configuration manners includes the following several implementation manners.

[0059] In the first scheme, the signal conditioning device relays a first uplink signal using a first codebook and relays a second uplink signal using a second codebook.

[0060] It is understood that when the second configuration information includes codebook modification information, the signal adjustment device may obtain the second codebook based on the codebook modification information. Of the uplink signals repeatedly transmitted by the terminal, the signal adjustment device relays the first uplink signal using the first codebook and relays the second uplink signal using the second codebook. In this way, the relay method of the first uplink signal is different from the relay method of the second uplink signal.

[0061] In the second scheme, the first uplink signal is relayed using the first codebook, and the second uplink signal is relayed using a third codebook obtained by changing the phase of the first codebook.

[0062] It is understood that when the second configuration information includes phase modification information, the signal adjustment device may modify the phase of the first codebook according to the phase modification information to obtain the third codebook. Of the uplink signals repeatedly transmitted by the terminal, the signal adjustment device relays the first uplink signal using the first codebook and relays the second uplink signal using the third codebook. In this way, the relay method of the first uplink signal is different from the relay method of the second uplink signal.

[0063] In the third scheme, the first uplink signal is relayed according to the first codebook, and the second uplink signal is relayed according to the relay outage strategy.

[0064] It is understood that when the second configuration information includes relay stop instruction information, among the uplink signals repeatedly transmitted by the terminal, the signal adjustment device may use the first codebook to relay the first uplink signal and use a relay stop strategy to relay the second uplink signal. Specifically, to stop relaying, when relaying the second uplink signal, the panel may be closed.

[0065] Exemplarily, the second configuration information is issued to the signal conditioning device in one of the following ways:

[0066] In the first method, Network devices and When a connection with the signal conditioning device is established, second configuration information is issued to the signal conditioning device.

[0067] It is understood that when adding a RIS or Smart Repeater, the network device may emit the second configuration information as part of the existing communication content in a semi-static manner. When the terminal needs to send a random access response, it notifies the RIS / Smart Repeater of the activation signaling of the second configuration information via a new reference signal, data packet, etc.

[0068] In the second scheme, when a random access response message is sent, second configuration information is sent to a signal coordinating device.

[0069] It is understood that when the terminal needs to send a random access response, the network equipment may issue the second configuration information to the RIS / Smart Repeater in a dynamic manner via a new reference signal, data packet, etc., and activate it directly.

[0070] In step S130, when the terminal receives a number of uplink signals repeatedly transmitted based on the random access response message, the terminal determines the type of the terminal based on the receiving conditions of the uplink signals.

[0071] The types of terminals described in the embodiments of the present disclosure include a first type and a second type, where the first type represents that the terminal directly accesses the network equipment, and the second type represents that the terminal accesses the network equipment through a signal conditioning device.

[0072] In an embodiment of the present disclosure, determining the type of terminal based on the reception status of an uplink signal specifically means determining the type of terminal based on signal quality information of a plurality of received uplink signals.

[0073] For example, the signal quality information may include information such as Reference Signal Receiving Power (RSRP), Signal to Interference plus Noise Ratio (SINR), Channel Quality Indicator (CQI), Reference Signal Received Quality (RSRQ), etc.

[0074] Exemplarily, as shown in FIG. 4, determining the type of the terminal based on the signal quality information of the received multiple uplink signals specifically includes, but is not limited to, the following steps S131 to S133.

[0075] In step S131, a first signal quality information of a first uplink signal among the received multiple uplink signals is obtained.

[0076] In step S132, obtain second signal quality information of a second uplink signal of the received plurality of uplink signals.

[0077] In step S133, it is determined whether the difference value between the first signal quality information and the second signal quality information is equal to or less than a preset difference threshold. If the difference value between the first signal quality information and the second signal quality information is equal to or less than the preset difference threshold, it is determined that the type of the terminal is the first type. If the difference value between the first signal quality information and the second signal quality information is greater than the preset difference threshold, it is determined that the type of the terminal is the second type.

[0078] In an embodiment of the present disclosure, the signal quality information of the first uplink signal is compared with the signal quality information of the second uplink signal to determine whether the currently received multiple repeated uplink signals are transmitted by a first type terminal or a second type terminal. It is understood that when transmitted by a first type terminal, there is no significant difference between the signal quality of the first uplink signal and the second uplink signal received at the network equipment side, and when transmitted by a second type terminal, there is a significant difference between the signal quality of the first uplink signal and the second uplink signal received at the network equipment side because the signal from the second type terminal needs to go through a signal conditioning device and the signal conditioning device relays the first uplink signal and the second uplink signal in a different manner.

[0079] For example, when the panel of the RIS is closed, the RSRP and SINR of the second uplink signal transmitted by the second type terminal received by the network device are very small, and are significantly different from the RSRP and SINR of the second transmission signal transmitted by the second type terminal received when the panel of the RIS is open. In the embodiment of the present disclosure, a reasonable difference threshold is set based on this, and it is determined whether the difference value between the first signal quality information corresponding to the first uplink signal and the second signal quality information corresponding to the second uplink signal is greater than the difference threshold, and further it is determined whether the terminal is a first type terminal or a second type terminal.

[0080] It is understood that a plurality of signal quality information may be combined as a judgment factor to improve the identification accuracy of the type of the terminal. Illustratively, the first signal quality information includes a first RSRP and a first SINR, the second signal quality information includes a second RSRP and a second SINR, and the difference threshold includes an RSRP difference threshold and an SINR difference threshold. Determining that the type of the terminal is the second type when the difference value between the first signal quality information and the second signal quality information is greater than the preset difference threshold includes determining that the type of the terminal is the second type when the difference value between the first RSRP and the second RSRP is greater than the preset RSRP difference threshold and the difference value between the first SINR and the second SINR is greater than the preset SINR difference threshold.

[0081] When there are a plurality of first uplink signals and a plurality of second uplink signals, the first signal quality information may be obtained by averaging signal quality information corresponding to the plurality of first uplink signals, and the second signal quality information may be obtained by averaging signal quality information corresponding to the plurality of second uplink signals.

[0082] For example, when there are a plurality of first uplink signals and a plurality of second uplink signals, the first RSRP is an average value of RSRPs corresponding to the plurality of first uplink signals, the first SINR is an average value of SINRs corresponding to the plurality of first uplink signals, the second RSRP is an average value of RSRPs corresponding to the plurality of second uplink signals, and the second SINR is an average value of SINRs corresponding to the plurality of second uplink signals.

[0083] As shown in Figure 5, it is a flowchart of a control method for a random access process according to an embodiment of the present disclosure. The method is applied to the signal conditioning device side and includes the following steps S210 to S220. Hereinafter, each of steps S210 to S220 will be described in order.

[0084] In step S210, when the terminal receives a plurality of uplink signals repeatedly transmitted according to the random access response message, the terminal obtains second configuration information issued by the network device.

[0085] In step S220, a plurality of uplink signals are relayed to the network device according to the second configuration information, the plurality of uplink signals including a first uplink signal and a second uplink signal, and the first uplink signal and the second uplink signal are relayed in different configuration manners, so that the network device determines the type of the terminal according to the receiving conditions of the uplink signals.

[0086] In an embodiment of the present disclosure, after receiving second configuration information issued by a network device, when receiving multiple uplink signals repeatedly transmitted from a terminal, the signal adjustment device relays a first uplink signal and a second uplink signal among these uplink signals in different manners based on the second configuration information.

[0087] Specifically, the terminal initiates a random access request to a network device, and the network device sends a random access response to the terminal. After the terminal receives the random access response, it repeatedly sends a plurality of uplink signals to the network device according to the first configuration information preset. The uplink signals include a PUSCH in the random access process or a third message sent by the terminal.

[0088] It is understood that the first uplink signal and the second uplink signal are different signals among a plurality of uplink signals repeatedly transmitted by the terminal, and the first uplink signal and the second uplink signal may each include one or more signals.

[0089] In one example, the first uplink signal represents the i-th uplink signal among the multiple uplink signals repeatedly transmitted by the terminal, where i is an odd number. The second uplink signal represents the j-th uplink signal among the multiple uplink signals repeatedly transmitted by the terminal, where j is an even number. For example, after receiving a random access response from the network device, the terminal repeatedly transmits four uplink signals, of which the first and third signals belong to the first uplink signal, and the second and fourth signals belong to the second uplink signal.

[0090] The first uplink signal and the second uplink signal may represent one or more specific signals among a plurality of uplink signals repeatedly transmitted by the terminal. For example, after receiving a random access response from the network device, the terminal repeatedly transmits four uplink signals, among which the first uplink signal identifies the first signal and the second signal, and the second uplink signal identifies the third signal and the fourth signal.

[0091] Exemplarily, the second configuration information includes at least one of a time domain start position of the repeated transmission, a time domain interval of the repeated transmission, the number of repeated transmission signals, codebook modification information, phase modification information, and relay stop instruction information.

[0092] Here, the time domain start position of the repeated transmission indicates the time domain position of a first uplink signal among multiple uplink signals repeatedly transmitted by the terminal, and the signal adjustment device may determine the start position at which the uplink signal is received based on the time domain start position.

[0093] The time domain interval of the repeated transmission indicates the time domain interval of the multiple uplink signals that are repeatedly transmitted, and the signal coordinating device may receive the uplink signals that are repeatedly transmitted by the terminal based on the time domain interval.

[0094] The number of repeated transmission signals indicates the number of uplink signals repeatedly transmitted by the terminal, and the signal adjustment device may receive a corresponding number of uplink signals based on the number of repeated transmission signals.

[0095] The codebook modification information allows the signal conditioning device to modify the first codebook, specifically, may be a codebook index, so as to allow the signal conditioning device to obtain the second codebook according to the codebook index. It is understood that the second codebook is a codebook different from the first codebook, and the first codebook is the codebook originally used by the signal conditioning device to relay the current terminal signal.

[0096] The phase change information is used to derive the third codebook by causing the signal conditioner to change the phase of the first codebook.

[0097] The relay stop instruction information is used to cause the signal coordinator to relay a part of the uplink signal repeatedly transmitted by the terminal using a relay stop strategy.

[0098] It should be understood that the second configuration information may include one or more of the time domain start position of the repeated transmission, the time domain interval of the repeated transmission, the number of repeated transmission signals, codebook modification information, phase modification information, and relay stop instruction information, and the specific content of the second configuration information is not limited in the embodiments of the present disclosure.

[0099] Illustratively, the signal conditioning device relaying the first uplink signal and the second uplink signal in different configuration manners includes the following several implementation manners.

[0100] In the first scheme, the signal conditioning device relays a first uplink signal using a first codebook and relays a second uplink signal using a second codebook.

[0101] It is understood that when the second configuration information includes codebook modification information, the signal adjustment device may obtain the second codebook based on the codebook modification information. Of the uplink signals repeatedly transmitted by the terminal, the signal adjustment device relays the first uplink signal using the first codebook and relays the second uplink signal using the second codebook. In this way, the relay method of the first uplink signal is different from the relay method of the second uplink signal. Here, the first codebook and the second codebook are different codebooks.

[0102] In the second scheme, the first uplink signal is relayed using the first codebook, and the second uplink signal is relayed using a third codebook obtained by changing the phase of the first codebook.

[0103] It is understood that when the second configuration information includes phase modification information, the signal adjustment device may modify the phase of the first codebook according to the phase modification information to obtain the third codebook. Of the uplink signals repeatedly transmitted by the terminal, the signal adjustment device relays the first uplink signal using the first codebook and relays the second uplink signal using the third codebook. In this way, the relay method of the first uplink signal is different from the relay method of the second uplink signal.

[0104] In the third scheme, the first uplink signal is relayed according to the first codebook, and the second uplink signal is relayed according to the relay outage strategy.

[0105] It is understood that when the signal adjustment device is a RIS and the second configuration information includes relay stop instruction information, among the uplink signals repeatedly transmitted by the terminal, the RIS may use a first codebook to relay the first uplink signal and use a relay stop strategy to relay the second uplink signal. Specifically, when relaying the second uplink signal, the panel may be closed to stop relaying.

[0106] Exemplarily, the signal conditioning device may obtain the second configuration information emitted by the network device in one of the following two ways.

[0107] In the first method, Network devices and When a connection with the network device is established, second configuration information is received from the network device.

[0108] It is understood that when adding a RIS or Smart Repeater, the network device may emit the second configuration information as part of the existing communication content in a semi-static manner. When the terminal needs to emit a random access response, it notifies the RIS / Smart Repeater of the activation signaling of the second configuration information via a new reference signal, data packet, etc., so as to make the RIS / Smart Repeater detect the uplink signal of the terminal's repeat transmission.

[0109] In the second manner, when receiving a random access response message of the network device, second configuration information is received from the network device.

[0110] It is understood that when the terminal needs to issue a random access response, the network equipment may issue the second configuration information to the RIS / Smart Repeater in a dynamic manner via a new reference signal, data packet, etc., and activate it directly.

[0111] It is understood that the signal conditioning device receives the random access response message from the network equipment and forwards the random access response message to the terminal.

[0112] The random access response message may carry first configuration information, and the first configuration information instructs the terminal to repeatedly transmit a plurality of uplink signals after receiving the random access response message. The first configuration information includes at least one of a time domain start position of the repeated transmission, a time domain interval of the repeated transmission, and a number of the repeated transmission signals. Here, the time domain start position of the repeated transmission indicates a time domain position of a first uplink signal among the plurality of uplink signals of the repeated transmission, specifically, indicates an offset interval in units of a time slot or a symbol, that is, the repeated transmission of the uplink signal may start after the offset interval has elapsed from the reception time of the random access response message. The time domain interval of the repeated transmission indicates a transmission time domain interval of the repeatedly transmitted uplink signal, that is, indicates a signal time domain interval repeatedly transmitted twice, and the unit is a time slot, a symbol, etc. The number of the repeated transmission signals indicates the number of repeated transmissions of the repeatedly transmitted uplink signal, for example, if the transmission is repeated four times, the number of the repeated transmission signals is four.

[0113] It is understood that signals relayed in different ways have a large difference on the network equipment side. Meanwhile, the multiple uplink signals that the terminal repeatedly transmits directly to the network equipment are not specially processed, so there is no large difference on the network equipment side. In this way, the network equipment can determine whether these uplink signals are relayed through a signal conditioning device or transmitted directly by the terminal based on whether there is a large difference between the received repeatedly transmitted uplink signals. For example, the type of the terminal is determined based on the signal quality information of the received multiple uplink signals.

[0114] As shown in Figure 6, a control method for a random access process according to an embodiment of the present disclosure is applied to a terminal and includes the following steps S310 to S330.

[0115] In step S310, when receiving a random access response message from the network device, obtain the first configuration information issued by the network device.

[0116] In an embodiment of the present disclosure, the terminal initiates a random access request to a network device, and the network device sends a random access response to the terminal. After receiving the random access response, the terminal repeatedly sends a plurality of uplink signals to the network device according to the first configuration information preset.

[0117] The uplink signal includes a third message in a random access process or a physical uplink shared channel PUSCH.

[0118] As an example, when a terminal initiates a contention-based random access request to a network device, the terminal repeatedly transmitting multiple uplink signals to the network device may be repeatedly transmitting a third message (Msg3) in multiple random access processes to the network device.

[0119] As another example, the terminal repeatedly transmits a plurality of uplink signals to the network device may be repeatedly transmitting a plurality of PUSCHs to the network device. After receiving the uplink resources allocated by the network device, the terminal may repeatedly transmit the PUSCHs to the network device based on the allocated uplink resources.

[0120] It should be understood that the uplink signal repeatedly transmitted by the terminal may be other types of signals, but the embodiments of the present disclosure are not limited thereto.

[0121] The first configuration information in the embodiment of the present disclosure includes at least one of a time domain start position of the repeated transmission, a time domain interval of the repeated transmission, and a number of the repeated transmission signals. Here, the time domain start position of the repeated transmission indicates a time domain position of a first uplink signal among the multiple uplink signals of the repeated transmission, specifically, indicates one offset interval in units of a time slot or a symbol, that is, the repeated transmission of the uplink signal may start after the above offset interval has elapsed from the reception time of the random access response message. The time domain interval of the repeated transmission indicates a transmission time domain interval of the repeatedly transmitted uplink signal, that is, indicates a time domain interval between signals repeatedly transmitted twice, in units of a time slot, a symbol, etc. The number of the repeated transmission signals indicates the number of repeated transmissions of the repeatedly transmitted uplink signal, for example, when the transmission is repeated four times, the number of the repeated transmission signals is four. Of course, the first configuration information may include more or less information than the above. For example, the first configuration information may not indicate a time domain start position of the repeated transmission, and the terminal may use a default offset interval to determine the time domain start position of the repeated transmission. The first configuration information may not specify a time domain interval for repeated transmission, and the terminal may use a default time domain interval to perform repeated transmission. Also, the first configuration information may not specify the number of repeated transmission signals, and the terminal may use the default number of repeated transmission signals to perform repeated transmission.

[0122] It is understood that the terminal may obtain the first configuration information in any of the following manners.

[0123] In the first manner, the first configuration information is obtained from random access channel RACH configuration information sent by a network device, and the random access channel RACH configuration information includes an information element carrying the first configuration information.

[0124] Here, the RACH configuration information may be RACH-Config Common information or other level signaling, but is not limited thereto in the embodiment of the present disclosure.

[0125] Take the case where RACH-Config Common information is RACH configuration information as an example, so that the first configuration information is carried in the RACH-Config Common information, a field related to the first configuration information may be added to the information element (IE) of the RACH-Config Common information. As shown in Figure 3, which is a schematic diagram of the format of RACH-Config Common information, where the field related to the first configuration information includes K2-offset-repetition and repetition-Number-Msg3. Here, K2-offset-repetition means the time domain interval of repeated transmission, and repetition-Number-Msg3 means the number of repeated transmission signals.

[0126] In the second scheme, the first configuration information is obtained from the random access response message, and the first configuration information is carried in the random access response message.

[0127] It is understood that the terminal may obtain the first configuration information issued by the network device through the RAR message in the random access process, i.e., may carry the first configuration information in the RAR message in the random access process. The RAR message here may specifically be the second message in the random access process (including a contention-based random access manner or a non-contention-based random access manner). Specifically, the fields related to the first configuration information, such as: K2 +j (time domain start position of repetition transmission), K2-offset-repetition (time domain interval of repetition transmission), and repetition-Number-Msg3 (number of repetition transmission signals), etc. may be added to the RAR message.

[0128] The types of terminals described in the embodiment of the present disclosure include a first type and a second type. Here, the first type represents that the terminal directly accesses the network equipment, and the second type represents that the terminal accesses the network equipment through a signal conditioning device. If the terminal is a first type terminal, execute the following step S320. If the terminal is a second type terminal, execute the following step S330.

[0129] In step S320, repeatedly transmitting a plurality of uplink signals to the network device based on the first configuration information, the network device determines the type of the terminal based on the receiving conditions of the uplink signals.

[0130] The first type of terminal transmits the uplink signal directly to the network equipment without any special processing for any uplink signal.

[0131] In step S330, repeatedly sending a plurality of uplink signals to a signal conditioning device according to the first configuration information, and relaying the plurality of uplink signals to a network device via the signal conditioning device, so that the network device determines a type of the terminal according to a receiving state of the uplink signals, where the plurality of uplink signals include a first uplink signal and a second uplink signal, and the first uplink signal and the second uplink signal are relayed by the signal conditioning device in different configuration manners.

[0132] In an embodiment of the present disclosure, the multiple uplink signals repeatedly transmitted by the terminal include a first uplink signal and a second uplink signal. Specifically, the first uplink signal and the second uplink signal are different signals among the multiple uplink signals repeatedly transmitted by the terminal. The first uplink signal may include one or more signals, and the second uplink signal may include one or more signals.

[0133] In one example, the first uplink signal represents the i-th uplink signal among the multiple uplink signals repeatedly transmitted by the terminal, where i is an odd number. The second uplink signal represents the j-th uplink signal among the multiple uplink signals repeatedly transmitted by the terminal, where j is an even number. For example, after receiving a random access response from the network device, the terminal repeatedly transmits four uplink signals, of which the first and third signals belong to the first uplink signal, and the second and fourth signals belong to the second uplink signal.

[0134] The first uplink signal and the second uplink signal may represent one or more specific signals among a plurality of uplink signals repeatedly transmitted by the terminal. For example, after receiving a random access response from the network device, the terminal repeatedly transmits four uplink signals, among which the first uplink signal identifies the first signal and the second signal, and the second uplink signal identifies the third signal and the fourth signal.

[0135] It is understood that the second type terminal repeatedly transmits uplink signals to the signal conditioning device, among which the first uplink signal and the second uplink signal are relayed by the signal conditioning device in different configuration manners. Specifically, the implementation manner includes the following several manners:

[0136] In the first scheme, the signal conditioning device relays a first uplink signal using a first codebook and relays a second uplink signal using a second codebook.

[0137] It is understood that when the second configuration information includes codebook modification information, the signal adjustment device may obtain the second codebook based on the codebook modification information. Of the uplink signals repeatedly transmitted by the terminal, the signal adjustment device relays the first uplink signal using the first codebook and relays the second uplink signal using the second codebook. In this way, the relay method of the first uplink signal is different from the relay method of the second uplink signal.

[0138] In the second scheme, the first uplink signal is relayed using the first codebook, and the second uplink signal is relayed using a third codebook obtained by changing the phase of the first codebook.

[0139] It is understood that when the second configuration information includes phase modification information, the signal adjustment device may modify the phase of the first codebook according to the phase modification information to obtain the third codebook. Of the uplink signals repeatedly transmitted by the terminal, the signal adjustment device relays the first uplink signal using the first codebook and relays the second uplink signal using the third codebook. In this way, the relay method of the first uplink signal is different from the relay method of the second uplink signal.

[0140] In the third scheme, the first uplink signal is relayed according to the first codebook, and the second uplink signal is relayed according to the relay outage strategy.

[0141] It is understood that when the signal adjustment device is a RIS and the second configuration information includes relay stop instruction information, among the uplink signals repeatedly transmitted by the terminal, the RIS may use a first codebook to relay the first uplink signal and use a relay stop strategy to relay the second uplink signal. Specifically, when relaying the second uplink signal, the panel may be closed to stop relaying.

[0142] It is understood that signals relayed in different ways have a large difference on the network equipment side. Meanwhile, the multiple uplink signals that the terminal repeatedly transmits directly to the network equipment are not specially processed, so there is no large difference on the network equipment side. In this way, the network equipment can determine whether these uplink signals are relayed through a signal conditioning device or transmitted directly by the terminal based on whether there is a large difference between the received repeatedly transmitted uplink signals. For example, the type of the terminal is determined based on the signal quality information of the received multiple uplink signals.

[0143] In order to better understand the invention according to the embodiments of the present disclosure, some examples are described below.

[0144] Example 1:

[0145] As shown in Figure 7, it is a schematic flowchart of the embodiment 1. The scenario shown in Figure 7 is a repeated reporting process of Msg3 in a contention-based access scenario, which includes the following steps S401 to S406.

[0146] In step S401, the base station receives a master information block MIB and a system information block 1 The information of SIB1 is broadcast. The information element levels of SIB1 are, from top to bottom, SIB, ServingCellConfigCommonSIB, UplinkConfigCommonSIB, BWP-UplinkCommon, and RACH-ConfigCommon. Here, RACH-ConfigCommon carries an information element indicating the first configuration information, so that the UE can extract the first configuration information from SIB1, and the first configuration information is K2 +j (time domain starting position of the repetition transmission), K2-offset-repetition (time domain interval of the repetition transmission), and repetition-Number-Msg3 (number of repetition transmission signals).

[0147] In step S402, the UE initiates a contention-based random access process by reporting Msg1 to the base station.

[0148] In step S403, the base station issues Msg2 to the UE.

[0149] In step S404, the UE determines the time from the reception time of Msg2 based on the first configuration information. K2 Report the first Msg3 at a distance of +j slots.

[0150] In step S405, the UE reports the second Msg3 after an interval of K2-offset-repetition based on the first configuration information.

[0151] In step S406, the UE repeats the process until the (repeationNumber-Msg3)th Msg3 is reported. K2 Report Msg3 at intervals of -offset-repetition.

[0152] Example 2

[0153] As shown in Fig. 8, it is a flowchart of the embodiment 2. The scene shown in Fig. 8 is a PUSCH repetition reporting process in a non-contention based access scene, which includes the following steps S501 to S506.

[0154] In step S501, the source base station issues first configuration information to the UE through RRC reconfiguration signaling.

[0155] Here, the RRC reconfiguration signaling includes SCG (Secondary Cell Group) addition signaling of an LTE base station in EN-DC, SCG addition signaling of an NR base station in NR-DC, and cell handover signaling of an NR base station during cell handover. The information element levels of the RRC reconfiguration signaling are, from top to bottom, RRCRReconfiguration, ServingCellConfigCommon, UplinkConfigCommonSIB, BWP-UplinkCommon, and RACH-ConfigCommon. Here, the RACH-ConfigCommon level carries an information element indicating first configuration information, so that the UE extracts the first configuration information from the reconfiguration signaling, and the first configuration information is K2 +j (time domain starting position of the repetition transmission), K2-offset-repetition (time domain interval of the repetition transmission), and repetition-Number-Msg3 (number of repetition transmission signals) information.

[0156] In step S502, the UE initiates a contention-based random access process by reporting Msg1 to the target base station.

[0157] In step S503, the target base station issues Msg2 to the UE.

[0158] In step S504, the UE determines based on the first configuration information: K2 The first PUSCH is reported at a position spaced +j slots apart. The PUSCH is scheduled by a RAR UL grant.

[0159] In step S505, the UE reports the second PUSCH after an interval of K2-offset-repetition based on the first configuration information.

[0160] In step S506, the UE repeats the process until the (repeationNumber-Msg3)-th PUSCH is reported. K2 - Report PUSCH at intervals of offset-repetition.

[0161] Example 3

[0162] As shown in Fig. 9, it is a flowchart of the embodiment 3. The scenario shown in Fig. 9 is a process in which the base station dynamically instructs the RIS / Smart Repeater to enable the second configuration information, and includes the following steps S601 to S604.

[0163] In step S601, the base station issues Msg2 (the second message in the random access process) to the RIS / Smart Repeater, and then relays Msg2 to the UE by the RIS / Smart Repeater.

[0164] In step S602, the base station issues Msg2 and transmits the second configuration information carried by the new reference signal, data packet, etc. to the RIS / Smart Repeater, and then the RIS / Smart Repeater validates the second configuration information.

[0165] In step S603, the UE reports the first Msg3 (the third message in the random access process) to the RIS / Smart Repeater, and the RIS / Smart Repeater relays the first Msg3 to the base station according to the first codebook.

[0166] In step S604, the UE reports the second Msg3 (the third message in the random access process) to the RIS / Smart Repeater, and the RIS / Smart Repeater relays the second Msg3 to the base station according to the second codebook.

[0167] Example 4

[0168] As shown in Fig. 10, it is a flowchart of the embodiment 4. The scenario shown in Fig. 10 is a process in which the base station semi-dynamically instructs the RIS / Smart Repeater to enable the second configuration information, and includes the following steps 701 to 705.

[0169] Steps S In 701, the base station issues second configuration information via a dedicated interface with the RIS / Smart Repeater. Specifically, the second configuration information is added to the existing communication content by adding Msg3 or time domain position information of PUSCH ( K2 +j, K2-offset-repetition and repetition-Number-Msg3) and the second arrangement Add to the signal relay information (codebook modification information, phase modification information, or relay stop instruction information).

[0170] Steps SAt 702, the base station issues Msg2 to the RIS / Smart Repeater, which relays Msg2 to the UE.

[0171] Steps S In 703, the base station issues Msg2 and triggers the RIS / Smart Repeater to detect the UE's uplink signal by sending activation signaling of the second configuration information to the RIS / Smart Repeater via a new reference signal, data packet, etc.

[0172] Steps S In 704, after receiving Msg2, the UE K2 +j slots away, the first Msg3 is reported, and the corresponding RIS / Smart Repeater is 1st The first Msg3 is relayed using the first code at the time of Msg3.

[0173] Steps S In step 705, after reporting the first Msg3, the UE: K2 The second Msg3 is reported after the -offset-repetition interval, and the corresponding RIS / Smart Repeater relays by changing the codebook, changing the phase, or closing the panel at the time of the second Msg3.

[0174] Example 5

[0175] As shown in Fig. 11, it is a flowchart of the embodiment 5. The scenario shown in Fig. 10 is a process in which a base station identifies a UE, and includes the following steps S801 to S803.

[0176] In step S801, the UE reports the first Msg3, and the RIS / Smart Repeater relays the first Msg3 to the base station using the first codebook.

[0177] In step S802, the UE reports the second Msg3, and the RIS / Smart Repeater uses the second codebook to 2 The 3rd Msg3 is relayed to the base station.

[0178] In step S803, the base station performs a UE identification process, including calculating an RSRP difference value and a SINR difference value between the first Msg3 and the second Msg3, and determining that the UE is a UE accessed via a RIS / Smart Repeater if the RSRP difference value is greater than or equal to a preset RSRP difference threshold and the SINR difference value is greater than or equal to a preset SINR difference threshold.

[0179] In the invention according to the embodiment of the present disclosure, the network device issues first configuration information to the terminal, the first configuration information being used to instruct the terminal to repeatedly transmit a plurality of uplink signals after receiving a random access response message, the plurality of uplink signals including a first uplink signal and a second uplink signal, the network device issues second configuration information to a signal conditioning device, the second configuration information being used to instruct the signal conditioning device to relay the first uplink signal and the second uplink signal in different configuration manners, and when the network device receives the plurality of uplink signals repeatedly transmitted by the terminal based on the random access response message, the network device determines the type of the terminal based on the reception status of the uplink signals. Since the plurality of uplink signals transmitted by the terminal accessed through the signal conditioning device are relayed to the network device in different configuration manners by the signal conditioning device, there is a large difference between the uplink signals relayed in different configuration manners on the network device side, the network device can determine whether the uplink signals from the terminal are directly transmitted from the terminal or relayed through the signal conditioning device based on the difference between the plurality of received uplink signals, thereby realizing the identification of the type of the terminal in the access phase.

[0180] The embodiment of the present disclosure further provides a network device. As shown in FIG. 12, the network device 700 includes:

[0181] This includes, but is not limited to, a processor 710 and a memory 720 .
