Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and in particular to an information transmission method, device, equipment and storage medium. Background Art

[0002] In 4-step RACH (Random Access Channel), the base station obtains TA (Timing Advance) by detecting the PRACH preamble signal sent by the user, and notifies the user UE through RAR (Random Access Response). In the subsequent information transmission process, the UE makes the PUSCH (Physical Uplink Shared Channel) signal fall within the receiving time window of the base station. However, when multiple users access and the data transmission is short packet data, the use of the original 4-step RACH method leads to large data communication overhead and reduces data transmission efficiency. For the 2-step RACH scenario, since the UE continuously sends PRACH (Physical Random Access Channel) signals and PUSCH signals, the traditional 4-step RACH method cannot be applied in the 2-step RACH scenario, and the TA of MsgA PUSCH cannot be adaptively adjusted. Since the TAs of different users are different, a time window of the base station cannot accommodate all users, resulting in user signals out of the window, reducing the performance of the base station. Currently, a common method in the industry is that the base station uses multiple time windows to accommodate the signals of multiple users. However, due to the large number of time windows, the method of determining the time interval between different time windows is complicated, and there is interference between user signals in different time windows, which still affects the performance of the base station. Summary of the invention

[0029] In order to make the purpose, technical solution and advantages of the present application more clear, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0030] The embodiment of the present application aims to realize the uploading of PUSCH signals of multiple users in the 2-Step RACH scenario, solve the problem that the user's PUSCH signal exceeds the time window, reduce the complexity of determining the time window, and improve the performance of the base station. Since the base station and the user end have unified timing, the PUSCH time window position of the broadcast base station can be used to enable the user to adaptively adjust the time interval and transmission time between the PRACH signal and the PUSCH signal according to the received time window position, and control the PUSCH signal of each user to fall within the receiving time window of the base station.

[0031] Figure 1 is a flowchart of an information transmission method provided in an embodiment of the present application. The embodiment of the present application is applicable to the case where a PUSCH signal is transmitted between a base station and a client. The method can be executed by an information transmission device in an embodiment of the present application. The device can be implemented by software and / or hardware. The device is generally integrated in a receiving end, and the receiving end can include a base station. See Figure 1 , an information transmission method provided in an embodiment of the present application specifically includes the following steps:

[0032] Step 110: Send a synchronous broadcast signal to the client, wherein the synchronous broadcast signal includes timestamp information and physical layer uplink shared channel PUSCH time window position information.

[0033] Among them, the synchronous broadcast signal is a signal for synchronizing the time window information between the receiving end and the client. The synchronous broadcast signal can be broadcast by the base station to one or more clients. The synchronous broadcast signal can carry timestamp information and physical layer uplink shared channel PUSCH time window position information. The timestamp information can mark the sending time of the synchronous broadcast signal. The timestamp information can be used to determine the transmission delay between the receiving end and the client, and to improve the accuracy of the time window. For example, the higher the accuracy of the timestamp information, the higher the accuracy of the transmission delay between the receiving end and the client, and the client can send the PUSCH signal within the accurate time window. The physical layer uplink shared channel PUSCH time window position can be the time window position for the receiving end to receive the PUSCH signal, and the time window can be the time range for the receiving end to receive the PUSCH signal.

[0034] Specifically, the receiving end may send a synchronous broadcast signal to the client, wherein the number of the client may be one or more, and the sent synchronous broadcast signal may include time window position information and timestamp information of the receiving end receiving the PUSCH signal.

[0035] Step 120: Receive a PUSCH signal sent by the client according to the PUSCH time window position information.

[0036] In an embodiment of the present application, the receiving end can receive a PUSCH signal at a PUSCH time window position. The PUSCH time window position may include an opening time and duration of the time window. The receiving end can start acquiring the PUSCH signal at a time corresponding to the opening time and maintain a period of time to receive the PUSCH signal state. The length of the time period may be the duration of the PUSCH time window position.

[0037] In the embodiment of the present application, a synchronous broadcast signal is broadcast to the client, wherein the synchronous broadcast signal includes timestamp information and PUSCH time window position information, and a PUSCH signal is received in a time window corresponding to the PUSCH time window position information. The transmission of the client PUSCH signal is achieved by broadcasting the time window position information, preventing the client PUSCH signal from being out of the window, ensuring the signal reception performance of the receiving end, improving the time accuracy between the receiving end and the client based on the timestamp information, and further improving the accuracy of the PUSCH signal transmission.

[0038] Figure 2 is a flow chart of an information transmission method provided in an embodiment of the present application. The embodiment of the present application is a specific embodiment based on the above embodiment. Figure 2 The information transmission method of the embodiment of the present application includes the following steps:

[0039] Step 210: Send a synchronous broadcast signal to the client, wherein the synchronous broadcast signal includes timestamp information and physical layer uplink shared channel PUSCH time window position information.

[0040] Further, based on the above application embodiment, the timestamp information is the sending time of the synchronous broadcast signal.

[0041] In an embodiment of the present application, the receiving end can obtain the timestamp information corresponding to the sending time when sending a synchronous broadcast signal, wherein the timestamp information may specifically refer to the total number of seconds from the sending time to 00:00:00 Greenwich time on January 1, 1970. It can be understood that the higher the accuracy of the timestamp information, the more accurate the time window for receiving PUSCH information by the receiving end.

[0042] Step 220: Receive a physical layer random access channel PRACH signal sent by the client.

[0043] Among them, the PRACH signal can determine the configuration information such as the preamble format, time resources and frequency resources before the random access process, which can facilitate the reception of the PUSCH signal during the random access process.

[0044] In an embodiment of the present application, the receiving end can detect the physical layer random access channel PRACH signal sent by the client to determine whether the PRACH signal is received. When the receiving end detects the PRACH signal, it can receive the PUSCH signal at the time corresponding to the PUSCH time position information.

[0045] Step 230: Receive a PUSCH signal sent by the client according to the PUSCH time window position information.

[0046] In an embodiment of the present application, a synchronous broadcast signal carrying PUSCH time window position information and timestamp information is sent from a receiving end to a client, a PRACH signal sent by the client is detected, and the presence of a PRACH signal is determined. The PUSCH signal can be received according to the configuration information of the PRACH signal. The client receives the PUSCH signal of the client within the time corresponding to the PUSCH time window position information, thereby achieving accurate transmission of the PUSCH signal, preventing the PUSCH signal sent by the client from exceeding the time window range of the receiving end, reducing signal interference between different time windows, and improving the system's PUSCH signal resolution performance.

[0047] Further, based on the above application embodiment, the PUSCH time window position information includes the time window start time and the time window duration.

[0048] Specifically, the position of the PUSCH time window can be represented by the time window start time and the time window duration, wherein the time window start time can be the start time of receiving the PUSCH signal, the time window duration can be the duration of the time window, and the receiving end can continue to receive the PUSCH signal for a period of time after the time window start time, and the length of the period of time can be specifically the time window duration. Further, the PUSCH time position information can also be represented by the time window start time and the time window end time, and the receiving end can receive the PUSCH signal in the time period corresponding to the time window start time and the time window end time.

[0049] Further, based on the above application embodiment, the PUSCH time window position information in the synchronized broadcast signal includes position information of at least one PUSCH time window.

[0050] In an embodiment of the present application, the synchronized broadcast signal may carry location information of one or more PUSCH time windows, and the receiving end may open corresponding time windows in sequence according to the location information of each PUSCH time window to receive the PUSCH signal.

[0051] Figure 3is a flowchart of another information transmission method provided in an embodiment of the present application. The embodiment of the present application is applicable to the case where a PUSCH signal is transmitted between a base station and a client. The method can be executed by an information transmission device in an embodiment of the present application. The device can be implemented by software and / or hardware. The device is generally integrated in the client. See Figure 3 , an information transmission method provided in an embodiment of the present application specifically includes the following steps:

[0052] Step 310: Acquire a synchronous broadcast signal sent by a receiving end, wherein the synchronous broadcast signal includes timestamp information and physical layer uplink shared channel PUSCH time window position information.

[0053] Specifically, the client may obtain the synchronous broadcast signal, and may extract the timestamp information and the PUSCH time window information in the synchronous broadcast signal.

[0054] Further, based on the above application embodiment, the timestamp information is the sending time of the synchronous broadcast signal.

[0055] Step 320: Determine a transmission delay according to the timestamp information, and determine a sending time of a PUSCH signal based on the transmission delay and the PUSCH time window position information.

[0056] In an embodiment of the present application, the timestamp information may be the sending time of the synchronous broadcast signal at the receiving end, and the transmission delay between the receiving end and the client may be determined by the receiving time of the synchronous broadcast signal and the sending time. Since there is a transmission delay between the receiving end and the client, in order for the PUSCH signal sent by the client to fall within the time window when it arrives at the receiving end, the sending time of the PUSCH signal must satisfy a time range, and the starting point of the time range is earlier than the start time of the PUSCH time window, and the end point of the time range is also earlier than the end time of the PUSCH time window. The time range corresponding to the PUSCH signal can be specifically determined by the difference between the PUSCH time window position information and the transmission delay. It can be understood that when the sending time of the PUSCH signal satisfies a time range, all symbols of the PUSCH signal can fall exactly within the time window of the receiving end.

[0057] Step 330: Send the PUSCH signal to the receiving end according to the sending time.

[0058] Specifically, the client sends the PUSCH signal according to the sending time, so that the PUSCH signal can fall within the PUSCH time window of the receiving end.

[0059] In an embodiment of the present application, a synchronous broadcast signal carrying timestamp information and PUSCH time window position information is used to determine the sending time of the PUSCH signal according to the timestamp information and the PUSCH time window position information, and the PUSCH signal is sent according to the sending time, thereby achieving accurate uploading of the PUSCH signal, so that the PUSCH signal sent by the client falls within the time window of the receiving end, avoiding signal interference between different time windows, and improving the parsing efficiency of the PUSCH signal.

[0060] Figure 4 is a flowchart of another information transmission method provided by an embodiment of the present application. The embodiment of the present application is a specific embodiment based on the above-mentioned embodiment of the application. By improving the transmission time accuracy of the client according to the duration of the PUSCH signal, the transmission time interval between the PUSCH signal and the PRACH signal is adjusted based on the transmission time of the PUSCH signal. Figure 4 The information transmission method provided in the embodiment of the present application includes the following steps:

[0061] Step 410: Acquire a synchronous broadcast signal sent by a receiving end, wherein the synchronous broadcast signal includes timestamp information and physical layer uplink shared channel PUSCH time window position information.

[0062] Step 420: Obtain the reception time of the synchronous broadcast signal, and determine the difference between the timestamp information and the reception time as the transmission delay corresponding to the synchronous broadcast signal.

[0063] Step 430: Determine a time range according to the duration of the PUSCH signal, the transmission delay, and the PUSCH time window position information.

[0064] Among them, the time range can be the time range within which the receiving end makes the PUSCH signal fall within the receiving end PUSCH time window.

[0065] In an embodiment of the present application, the PUSCH signal is composed of multiple symbols, and the transmission of the PUSCH signal can last for a period of time. Therefore, the time range for sending the PUSCH signal can be determined according to the duration of the PUSCH signal, the transmission delay and the PUSCH time window so that the first symbol and the last symbol of the PUSCH signal both fall within the PUSCH time window.

[0066] Further, based on the above application embodiment, the time range is t w -ΔT d ≤t PUSCH ≤t w +T w -T PUSCH -ΔT d , where t PUSCHis the transmission time of the starting symbol in the PUSCH signal, t w is the start time of the time window, T w is the time window duration, ΔT d is the transmission delay, T PUSCH is the duration of the PUSCH signal.

[0067] Step 440: Select a transmission time of a PUSCH signal within the time range.

[0068] Specifically, the client sends the PUSCH signal according to the time point corresponding to the time range, so that all symbols of the PUSCH signal fall within the time window of the receiving end. Therefore, a time point can be randomly selected within the time range as the sending time of the PUSCH signal. It can be understood that there is no unique way to select the sending time of the PUSCH signal within the time range, and the starting time point or the ending time point of the time range or any time point between the starting time point and the ending time point can be selected as the sending time.

[0069] Step 450: Determine a transmission time interval between the PRACH signal and the PUSCH signal; and send a physical layer random access channel PRACH signal to the receiving end.

[0070] In an embodiment of the present application, there is a transmission time interval between the transmission time of the PRACH signal and the PUSCH signal in the RACH, and the transmission time interval between the PRACH signal and the PUSCH signal can be determined. There is no restriction on the transmission of the PRACH signal in the RACH, and the client can determine the transmission time of the PRACH signal through the determined transmission time interval. It can be understood that the PRACH signal is sent before the PUSCH signal, and the transmission time interval can be determined by the difference between the transmission time of the last symbol of the PRACH signal and the transmission time of the first symbol of the PUSCH signal.

[0071] Specifically, after determining the time interval between sending the PRACH signal and the PUSCH signal, the sending time of the PRACH signal is determined based on the sending time of the PUSCH signal and the sending time interval, and the client can send the PRACH signal according to the sending time of the PRACH signal.

[0072] Step 460: Send the PUSCH signal to the receiving end according to the sending time.

[0073] In the embodiment of the present application, the client estimates the transmission delay according to the timestamp information and the receiving time sent by the receiving end, and adaptively adjusts the sending time interval and sending time of the PRACH and PUSCH signals according to the PUSCH receiving window position predetermined by the receiving end, thereby realizing that the PUSCH signal falls within the access time window of the receiving end, reducing the user signal interference between the time windows, and improving the analysis performance of the PUSCH signal.

[0074] Further, based on the above application embodiment, the PUSCH time window position information includes the time window start time and the time window duration.

[0075] In an exemplary embodiment, the PUSCH time window position information in the synchronized broadcast signal includes position information of at least one PUSCH time window.

[0076] In an exemplary embodiment, Figure 5 is an example diagram of an information transmission method provided in an embodiment of the present application, see Figure 5 Taking the 2-step RACH between the base station and the user as an example, when the synchronous broadcast signal includes a PUSCH signal, an information transmission method provided by an embodiment of the present application includes the following steps:

[0077] Step 1: The base station sends a synchronous broadcast signal, and the synchronous broadcast signal includes timestamp information t BS , and the time window position of a subsequent scheduled PUSCH signal reception, the starting time of the time window is t w , the duration of the time window is T w .

[0078] Step 2: The user receives the synchronous broadcast signal, performs downlink synchronization, and analyzes the system information. BS , and its own timing t UE , estimate the transmission delay ΔT d =t UE -t BS . Assume that the sending time of MsgA PRACH signal is t PRACH , the signal duration is T PRACH , the sending time of MsgA PUSCH signal is t PUSCH , the signal duration is T PUSCH The user adaptively adjusts the sending time t of the MsgA PUSCH signal PUSCH , so that the sending time satisfies t w ≤t PUSCH +ΔT d ≤t w +T w -TPUSCH At the same time, the interval between MsgA PRACH signal and MsgA PUSCH signal is adjusted to ΔT accordingly. MsgA =t PUSCH -(t PRACH +T PRACH ), wherein the MsgA signal may include a PRACH signal and a PUSCH signal, the MsgA PRACH signal may be the PRACH signal part of the MsgA signal, used to transmit configuration information such as a preamble, and the MsgAPUSCH signal may be the PUSCH signal part of the MsgA, used to transmit uplink data.

[0079] Step 3: The base station detects the MsgA preamble and sends a message at the preset time window start time t w The MsgA PUSCH signal is received and the payload of the PUSCH signal is parsed. The user's adaptive adjustment of the sending time can make the MsgA PUSCH signal fall within the receiving time window of the base station. The base station can send the MsgB signal to the user based on the parsed content.

[0080] Taking the 2-step RACH between the base station and the user as an example, when the synchronous broadcast signal includes two PUSCH signals, an information transmission method provided in an embodiment of the present application includes the following steps:

[0081] Step 1: The base station sends a synchronous broadcast signal, including timestamp information t BS , and the subsequent scheduled two PUSCH signal reception time window positions, the start time of the time window is t w,1 and t w,2 , and t w,1 <t w,2 , and the duration of the time window is T w .

[0082] Step 2: The user receives the synchronous broadcast signal, performs downlink synchronization, and analyzes the system information. BS , and its own timing t UE , estimate the transmission delay ΔT d =t UE -t BS . Assume that the sending time of MsgA PRACH signal is t PRACH , the signal duration is T PRACH , the sending time of MsgA PUSCH signal is t PUSCH , the signal duration is T PUSCHThe user adaptively adjusts the sending time of the MsgA PUSCH signal and finds that it cannot meet t w，1 ≤t PUSCH +ΔT d ≤t w，1 +T w -T PUSCH , but can satisfy t w，2 ≤t PUSCH +ΔT d ≤t w，2 +T w -T PUSCH Therefore, the user's signal transmission time and interval are adaptively adjusted based on the second receiving window of the base station, and the interval time between the MsgA PRACH signal and the MsgA PUSCH signal is adjusted to ΔT accordingly. MsgA =t PUSCH -(t PRACH +T PRACH ).

[0083] Step 3: The base station detects the MsgA preamble and sends a message at the preset time window start time t w,1 The first time window and the starting time t w,2 The second time window receives the MsgA PUSCH signal and parses the signal payload. Since the user is adaptively adjusted based on the second time window, the base station cannot correctly parse the user signal in the first time window, but can correctly parse the user signal in the second time window. After that, the base station sends the MsgB signal to the user based on the parsed content.
