Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technology but is not limited to the field of wireless communication technology, and in particular to a method, apparatus, communication device and storage medium for wireless transmission. Background Art

[0002] In order to support IoT services, two major technologies, Machine Type Communication (MTC) and Narrow Band Internet of Things (NB-IoT), are proposed. These two technologies are mainly aimed at scenarios such as low rates and high latency. For example, scenarios such as meter reading and environmental monitoring. NB-IoT can only support a maximum rate of several hundred k, and MTC can only support a maximum rate of several M. However, with the continuous development of IoT services, such as the popularization of services such as video surveillance, smart homes, wearable devices, and industrial sensor monitoring. These services usually require a rate of tens to 100M, and also have relatively high requirements for latency. At this time, MTC and NB-IoT technologies are difficult to meet the requirements. Based on this situation, the Reduced Capability UE (RedCap) or NR-lite for short was introduced.

[0003] In the related art, there is a small data transmission (SDT) scenario. However, in the SDT scenario, the RedCap terminal does not have the same opportunity to execute SDT as the ordinary terminal, which limits the communication capability of the RedCap terminal. Summary of the invention

[0082] Please refer to Figure 1 , which shows a schematic diagram of the structure of a wireless communication system provided by an embodiment of the present disclosure. Figure 1 As shown, the wireless communication system is a communication system based on mobile communication technology, and the wireless communication system may include: a plurality of user equipments 110 and a plurality of base stations 120 .

[0083] Among them, the user equipment 110 can be a device that provides voice and / or data connectivity to the user. The user equipment 110 can communicate with one or more core networks via a radio access network (RAN). The user equipment 110 can be an Internet of Things user equipment, such as a sensor device, a mobile phone, and a computer with an Internet of Things user equipment. For example, it can be a fixed, portable, pocket-sized, handheld, computer-built-in or vehicle-mounted device. For example, a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote user device, an access terminal, a user terminal, a user agent, a user device, or a user equipment. Alternatively, the user equipment 110 can also be a device of an unmanned aerial vehicle.

Alternatively, the user equipment 110 may also be a roadside device, for example, a street lamp, a signal lamp, or other roadside device with a wireless communication function.

[0084] The base station 120 may be a network-side device in a wireless communication system. The wireless communication system may be a fourth generation mobile communication technology (4G) system, also known as a long term evolution (LTE) system; or, the wireless communication system may be a 5G system, also known as a new air interface system or a 5G NR system. Alternatively, the wireless communication system may be a next generation system of the 5G system. The access network in the 5G system may be referred to as NG-RAN (New Generation-Radio Access Network).

[0085] Among them, the base station 120 can be an evolved base station (eNB) adopted in the 4G system. Alternatively, the base station 120 can also be a base station (gNB) adopting a centralized distributed architecture in the 5G system. When the base station 120 adopts a centralized distributed architecture, it usually includes a centralized unit (CU) and at least two distributed units (DU).

[0088] Here, the above-mentioned user equipment can be considered as the terminal equipment of the following embodiments.

[0089] In some embodiments, the wireless communication system may further include a network management device 130 .

[0090] Several base stations 120 are respectively connected to a network management device 130. The network management device 130 may be a core network device in a wireless communication system. For example, the network management device 130 may be a mobility management entity (MME) in an evolved packet core (EPC).

The embodiments of the present disclosure do not limit the implementation form of the network management device 130.

[0091] In order to facilitate the understanding of those skilled in the art, the embodiments of the present disclosure list multiple implementation methods to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the multiple embodiments provided by the embodiments of the present disclosure can be executed separately, or can be executed together with the methods of other embodiments of the embodiments of the present disclosure, or can be executed together with some methods in other related technologies separately or in combination; the embodiments of the present disclosure do not limit this.

[0092] In order to better understand the technical solutions described in any embodiment of the present disclosure, first, the application scenarios in the related technologies are described:

[0093] In one scenario embodiment, a solution is proposed to support small data packet transmission (SDT) in the inactive state of radio resource control (RRC). That is to say, the terminal can complete the transmission of small data packets without entering the RRC connection state, so as to reduce the waste of time and frequency resources, shorten the data transmission delay, and save terminal energy consumption.

[0094] In one embodiment, small data packet transmission supports two modes: SDT based on random access process and SDT based on semi-static configuration (CG, Configured Grant). Among them, SDT based on semi-static configuration is that when the base station converts from RRC connected state to RRC inactive state, the base station carries the semi-static time-frequency domain resource allocation information and timing advance (TA, Timing Advance) and other information required for SDT transmission in the RRC resume (resume) or release (release) message. When the terminal has uplink data to transmit in the RRC inactive state, it first determines the validity of the TA and the size of the data packet. When the threshold is met (for example, see Figure 2 When the threshold value 3 in the figure is reached, the semi-static resources configured by the base station are used to transmit small data packets.

[0095] In one embodiment, the SDT based on the random access process is divided into two modes, namely, SDT based on 2-step random access (2-step) and SDT based on 4-step random access (4-step). Among them, for the SDT based on 2-step random access, the small data packet will be transmitted in the physical uplink shared channel (PUSCH, Physical Uplink ShareCHannel) resource of the random access message A (msgA); and for the SDT based on 4-step random access, the small data packet will be carried in the third message (msg3). For the SDT based on random access, it is also necessary to judge the size of the data packet. Only when the size of the data packet is less than a certain threshold value can the small data packet be transmitted during the random access process. Otherwise, it is necessary to enter the connection state through the random access process before transmitting the small data packet. In addition to the limitation of the data packet size, the terminal must also compare the current synchronization signal reference signal received power (SS-RSRP, Synchronization SignalReference Signal Received Power) with the reference signal received power (RSRP, Reference SignalReceived Power) threshold before transmitting the small data packet. For example, please refer again Figure 2 , small data packets are transmitted only when the current SS-RSRP is greater than the RSRP threshold 1. The purpose of the RSRP threshold comparison here is to ensure that SDT transmission can be performed only under good coverage conditions to avoid wasting uplink transmission resources.

[0096] For random access-based SDT, whether to choose 2-step random access SDT or 4-step random access SDT, the RSRP threshold judgment is also required. In other words, please refer to Figure 2Only when SS-RSRP is greater than RSRP threshold 2, the terminal can use 2-step random access for SDT. Otherwise, 4-step random access is used for SDT. The purpose of RSRP threshold judgment here is to determine whether the terminal is located in the center of the cell. Only when the terminal is close to the base station, the cyclic prefix (CP) ) can make up for the size of TA, the terminal can use the 2-step random access method for SDT. Here, the threshold 1 mentioned above must be smaller than the threshold 2.

[0097] Similar to IoT devices in Long Term Evolution (LTE), NR-lite based on the fifth generation mobile communication network (5G) usually needs to meet the following requirements: low cost, low complexity; a certain degree of coverage enhancement; power saving. Since the new radio (NR) is designed for high-end terminals such as high speed and low latency, the current design cannot meet the above requirements of NR-lite. Therefore, the NR system needs to be modified to meet the requirements of NR-lite. For example, in order to meet the requirements of low cost and low complexity, the bandwidth of NR-IoT can be limited, for example, to 20MHz, or the size of the NR-lite buffer can be limited, thereby limiting the size of each received transmission block. For power saving, possible optimization directions are to simplify the communication process and reduce the number of times NR-lite users detect downlink control channels.

[0098] In the related art, since the RedCap terminal supports 1Rx and 2Rx in frequency range 1 (FR1, Frequency Range 1), and supports different numbers of antenna elements on different antenna panels in frequency range 2 (FR2, Frequency Range 2), the terminals have the same uplink transmission capability at the same location, but the measured RSRP values ​​are different. Finally, the RedCap terminals with 1Rx terminals or fewer antenna elements cannot have the same opportunity to use SDT.

[0099] like Figure 3 As shown, this embodiment provides a wireless transmission method, wherein the method is executed by a terminal, and the method includes:

[0100] Step 31: Determine a threshold value of signal transmission quality for performing small data packet transmission SDT based on the configuration information;

[0101] The configuration information is used to indicate at least one of the following:

[0102] A predetermined threshold value of signal transmission quality for performing SDT on a terminal having a first type of antenna structure;

[0103] A correction value of a reference threshold value of signal transmission quality of a terminal having a first type of antenna structure performing SDT.

[0104] Here, the terminal involved in the present disclosure may be, but is not limited to, a mobile phone, a wearable device, a vehicle-mounted terminal, a road side unit (RSU), a smart home terminal, an industrial sensor device and / or a medical device, etc. In some embodiments, the terminal may be a RedCap terminal or a predetermined version of a new air interface NR terminal (for example, an R17 NR terminal). It should be noted that the RedCap terminal may be an enhanced eRedCap terminal.

[0105] The access network equipment involved in the present disclosure can be various types of base stations, for example, base stations of third-generation mobile communication (3G) networks, base stations of fourth-generation mobile communication (4G) networks, base stations of fifth-generation mobile communication (5G) networks, or other evolved base stations.

[0106] In one scenario embodiment, before determining whether to perform SDT, the terminal may obtain the signal transmission quality of the synchronization signal and compare the signal transmission quality with the threshold value of the signal transmission quality. SDT is only performed when it is determined that the signal transmission quality is greater than the threshold value, otherwise SDT is not performed. In this way, the waste of resources can be reduced. Here, the signal transmission quality is used to indicate the transmission quality of the signal, which can be determined by at least one of the following parameters: reference signal received power (RSRP, Reference Singal Receiving Power), received signal strength indication (RSSI, Received Signal Strength Indicator), reference signal received quality (RSRQ, Reference Signal Receiving Quality) and signal to interference plus noise ratio (SINR, Signal to Interference plus Noise Ratio). It should be noted that the determination of signal transmission quality is not limited to the above parameters.

[0107] The small data packet in the present disclosure may be a data packet whose size or dimension is less than a predetermined threshold. The size or dimension of the data packet may be determined based on the number of bits in the information domain occupied by the data packet during transmission. Exemplarily, when the number of bits in the information domain occupied by the data packet during transmission is less than the quantity threshold, the data packet is determined to be a small data packet.

[0108] In one embodiment, in response to the measured signal transmission quality of the synchronization signal being greater than the threshold value of the signal transmission quality for the terminal to perform SDT and the size of the data packet to be transmitted being less than a predetermined threshold, SDT is performed. It should be noted that "less than" in the present disclosure has the meaning of "less than or equal to" in some scenarios, and "greater than" in the present disclosure has the meaning of "greater than or equal to" in some scenarios.

[0109] It should be noted that there may be multiple threshold values ​​for the signal transmission quality for the terminal to perform SDT. The multiple threshold values ​​can be used to determine whether to use the corresponding transmission mode to perform SDT. Exemplarily, the threshold value may include a first threshold value, a second threshold value, and a third threshold value, wherein the third threshold value is less than the second threshold value, and the second threshold value is less than the first threshold value. If the measured signal transmission quality of the synchronization signal is greater than the third threshold value and less than the second threshold value, the first transmission mode is used to perform SDT; or, if the measured signal transmission quality of the synchronization signal is greater than the second threshold value and less than the first threshold value, the second transmission mode is used to perform SDT; or, if the measured signal transmission quality of the synchronization signal is greater than the first threshold value, the third transmission mode is used to perform SDT. Among them, the first transmission mode may be an SDT mode based on 4-step random access, the second transmission mode may be an SDT mode based on 2-step random access, and the third transmission mode may be an SDT mode based on semi-static configuration.

[0110] It should be noted that for terminals with different types of antenna structures, the threshold values ​​of signal transmission quality for executing SDT configured may be different. Here, the terminal may include a terminal with a first type of antenna structure, etc. Exemplarily, the predetermined threshold values ​​of signal transmission quality for executing SDT configured for terminals with different types of antenna structures are different, or the correction values ​​of the reference thresholds of signal transmission quality for executing SDT configured for terminals with different types of antenna structures are different.

[0111] In one embodiment, the terminal may include a terminal having a first type of antenna structure. The first type of antenna structure includes one of the following: in response to the terminal operating in the frequency range FR1, the number of receiving antennas is a predetermined number; in response to the terminal operating in the frequency range FR2, the number of antenna elements included in a single antenna panel is less than a quantity threshold. Exemplarily, the predetermined number may be 1. The quantity threshold may be determined based on the antenna elements included in one antenna panel in an NR terminal. For example, the quantity threshold is the number of antenna elements included in one antenna panel in an NR terminal (non-RedCap UE, also referred to as a non-RedCap terminal or ordinary UE).

[0112] In one embodiment, the terminal determines a threshold value of signal transmission quality for the terminal to perform small data packet transmission SDT based on configuration information; wherein the configuration information is used to indicate: a predetermined threshold value of signal transmission quality for a terminal with a first type of antenna structure to perform SDT. If the terminal determines that the terminal is a terminal with the first type of antenna structure and the measured signal transmission quality of the synchronization signal is greater than the predetermined threshold value, SDT is performed.

[0113] In one embodiment, configuration information is determined based on a communication protocol. A threshold value of signal transmission quality for a terminal to perform small data packet transmission SDT is determined based on the configuration information; wherein the configuration information is used to indicate: a predetermined threshold value of signal transmission quality for a terminal having a first type of antenna structure to perform SDT. If the terminal determines that the terminal is a terminal with a first type of antenna structure and the measured signal transmission quality of the synchronization signal is greater than the predetermined threshold value, SDT is performed. Of course, the configuration information can also be preset in the terminal, and the specific scheme will not be repeated.

[0114] In one embodiment, configuration information sent by an access network device is received. Based on the configuration information, a threshold value of signal transmission quality for a terminal to perform small data packet transmission (SDT) is determined; wherein the configuration information is used to indicate: a predetermined threshold value of signal transmission quality for a terminal with a first type of antenna structure to perform SDT. If the terminal determines that the terminal is a terminal with a first type of antenna structure and the measured signal transmission quality of the synchronization signal is greater than the predetermined threshold value, SDT is performed.

[0115] In one embodiment, the terminal determines a threshold value of signal transmission quality for the terminal to perform small data packet transmission SDT based on configuration information; wherein the configuration information is used to indicate: a correction value of a reference threshold value of signal transmission quality for a terminal having a first type of antenna structure to perform SDT. If the terminal determines that the terminal is a terminal with a first type of antenna structure and the measured signal transmission quality of the synchronization signal is greater than the reference threshold value corrected by the correction value, SDT is performed. It should be noted that the reference threshold value may be a threshold value used when a non-RedCap terminal performs SDT, wherein a non-RedCap terminal may be understood as a terminal whose capability has not been reduced, such as an LTE terminal. The correction value may be an offset. Correcting the reference threshold value using the correction value may be subtracting the correction value from the reference threshold value. Here, all terminals (including RedCap terminals and non-RedCap terminals) may receive the reference threshold value in advance. The reference threshold value is a threshold value shared by all terminals.

[0116] It should be noted that, in one embodiment, the terminal may also use the correction value to correct the measured signal transmission quality of the synchronization signal after receiving the correction value. If the terminal determines that the terminal is a terminal of the first type of antenna structure and the corrected measured signal transmission quality of the synchronization signal is greater than the reference threshold value, SDT is executed. Here, using the correction value to correct the measured signal transmission quality of the synchronization signal may be to add the correction value on the basis of the measured signal transmission quality of the synchronization signal. It can be understood that in this embodiment, the reference threshold value is actually corrected, and compared with directly correcting the reference threshold value, it is only a change in the calculation form.

[0117] In one embodiment, configuration information is determined based on a communication protocol. A threshold value of signal transmission quality for a terminal to perform small data packet transmission SDT is determined based on the configuration information; wherein the configuration information is used to indicate: a correction value of a reference threshold value of signal transmission quality for a terminal having a first type of antenna structure to perform SDT. If the terminal determines that the terminal is a terminal with a first type of antenna structure and the measured signal transmission quality of the synchronization signal is greater than the reference threshold value corrected by the correction value, SDT is performed.

[0118] In one embodiment, configuration information sent by an access network device is received. Based on the configuration information, a threshold value of signal transmission quality for a terminal to perform small data packet transmission (SDT) is determined; wherein the configuration information is used to indicate: a correction value of a reference threshold value of signal transmission quality for a terminal having a first type of antenna structure to perform SDT. If the terminal determines that the terminal is a terminal with a first type of antenna structure and the measured signal transmission quality of the synchronization signal is greater than the reference threshold value corrected by the correction value, SDT is performed.

[0119] In an embodiment of the present disclosure, based on configuration information, a threshold value of signal transmission quality for a terminal to perform small data packet transmission SDT is determined; wherein the configuration information is used to indicate at least one of the following: a predetermined threshold value of signal transmission quality for a terminal having a first type of antenna structure to perform SDT; a correction value of a reference threshold value of signal transmission quality for a terminal having a first type of antenna structure to perform SDT. Here, since the configuration information indicates a predetermined threshold value of signal transmission quality for a terminal having a first type of antenna structure to perform SDT and / or a correction value of a reference threshold value of signal transmission quality for a terminal having a first type of antenna structure to perform SDT. The terminal can determine the threshold value of signal transmission quality for the terminal to perform SDT based on its own first type of antenna structure and the corresponding predetermined threshold value, and perform SDT based on the threshold value; or, the terminal can determine the threshold value of signal transmission quality for the terminal to perform SDT based on its own first type of antenna structure, the corresponding reference threshold value and the correction value, and perform SDT based on the threshold value. Since the predetermined threshold value and / or the correction value are configured for the first type of antenna structure, the predetermined threshold value and the correction value can be adapted to the first type of antenna structure. Compared with the method of using a fixed threshold value of SDT or a threshold value of a non-first type of antenna structure to execute SDT, the terminal of the first type of antenna structure can more easily meet the conditions for executing SDT, which can increase the chance of the terminal of the first type of antenna structure to execute SDT.

It should be noted that in this embodiment, the signal transmission quality of the measured synchronization signal can also be directly corrected by the correction value, and then the corrected signal transmission quality is compared with the reference threshold value. If the terminal determines that the terminal is a terminal of the first type of antenna structure and the corrected signal transmission quality is greater than the reference threshold value, SDT is executed. It can be understood that in this embodiment, the reference threshold value is actually corrected. Compared with directly correcting the reference threshold value, it is only a change in the calculation form.

[0144] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0145] like Figure 7As shown, this embodiment provides a wireless transmission method, wherein the method is performed by an access network device; the method includes:

[0146] Step 71: Send configuration information to the terminal;

[0147] The configuration information is used for the terminal to determine a threshold value of signal transmission quality for the terminal to perform small data packet transmission SDT based on the configuration information;

[0148] The configuration information is used to indicate at least one of the following:

[0149] A predetermined threshold value of signal transmission quality for performing SDT on a terminal having a first type of antenna structure;

[0150] A correction value of a reference threshold value of signal transmission quality of a terminal having a first type of antenna structure performing SDT.

[0151] Here, the terminal involved in the present disclosure may be, but is not limited to, a mobile phone, a wearable device, a vehicle-mounted terminal, a road side unit (RSU), a smart home terminal, an industrial sensor device and / or a medical device, etc. In some embodiments, the terminal may be a RedCap terminal or a predetermined version of a new air interface NR terminal (for example, an R17 NR terminal). It should be noted that the RedCap terminal may be an enhanced eRedCap terminal.

[0152] The access network equipment involved in the present disclosure can be various types of base stations, for example, base stations of third-generation mobile communication (3G) networks, base stations of fourth-generation mobile communication (4G) networks, base stations of fifth-generation mobile communication (5G) networks, or other evolved base stations.

[0153] In one embodiment, the access network device sends configuration information to the terminal; wherein the configuration information is used for the terminal to determine the threshold value of the signal transmission quality for the terminal to perform small data packet transmission SDT based on the configuration information; the configuration information is used to indicate at least one of the following: a predetermined threshold value of the signal transmission quality of the terminal with the first type of antenna structure to perform SDT; a correction value of the reference threshold value of the signal transmission quality of the terminal with the first type of antenna structure to perform SDT. Before determining whether to perform SDT, the terminal can obtain the signal transmission quality of the synchronization signal (for example, RSRP) and compare the signal transmission quality with the threshold value of the signal transmission quality. The terminal will only perform SDT if it is determined that the signal transmission quality is greater than the threshold value, otherwise the terminal will not perform SDT. In this way, the waste of resources can be reduced. Here, the signal transmission quality is used to indicate the transmission quality of the signal, which can be determined by at least one of the following parameters: reference signal received power (RSRP, Reference Singal Receiving Power), received signal strength indication (RSSI, Received Signal Strength Indicator), reference signal received quality (RSRQ, Reference Signal Receiving Quality) and signal to interference plus noise ratio (SINR, Signal to Interference plus Noise Ratio).

[0154] A small data packet in the present disclosure may be a data packet whose size or dimension (SIZE) is less than a predetermined threshold. The size or dimension of the data packet may be determined based on the number of bits in the information domain occupied by the data packet during transmission. Exemplarily, when the number of bits in the information domain occupied by the data packet during transmission is less than the number threshold, the data packet is determined to be a small data packet.

[0155] In one embodiment, the access network device sends configuration information to the terminal; wherein the configuration information is used for the terminal to determine a threshold value of signal transmission quality for the terminal to perform small data packet transmission SDT based on the configuration information; the configuration information is used to indicate at least one of the following: a predetermined threshold value of signal transmission quality for the terminal with a first type of antenna structure to perform SDT; a correction value of a reference threshold value of signal transmission quality for the terminal with a first type of antenna structure to perform SDT. In response to the measured signal transmission quality of the synchronization signal being greater than the threshold value of signal transmission quality for the terminal to perform SDT and the size of the data packet to be transmitted being less than the predetermined threshold, SDT is performed.

[0156] It should be noted that there may be multiple threshold values ​​for the signal transmission quality of the terminal to perform SDT. The multiple threshold values ​​can be used by the terminal to determine whether to use the corresponding transmission mode to perform SDT. Exemplarily, the threshold value may include a first threshold value, a second threshold value, and a third threshold value, wherein the third threshold value is less than the second threshold value, and the second threshold value is less than the first threshold value. If the measured signal transmission quality of the synchronization signal is greater than the third threshold value and less than the second threshold value, the terminal uses the first transmission mode to perform SDT; or, if the measured signal transmission quality of the synchronization signal is greater than the second threshold value and less than the first threshold value, the terminal uses the second transmission mode to perform SDT; or, if the measured signal transmission quality of the synchronization signal is greater than the first threshold value, the terminal uses the third transmission mode to perform SDT. Among them, the first transmission mode may be SDT based on 4-step random access, the second transmission mode may be SDT based on 2-step random access, and the third transmission mode may be SDT based on semi-static configuration.

[0157] It should be noted that for terminals with different types of antenna structures, the threshold values ​​of signal transmission quality for executing SDT configured may be different. Here, the terminal may include a terminal with a first type of antenna structure, etc. Exemplarily, the predetermined threshold values ​​of signal transmission quality for executing SDT configured for terminals with different types of antenna structures are different, or the correction values ​​of the reference thresholds of signal transmission quality for executing SDT configured for terminals with different types of antenna structures are different.

[0158] In one embodiment, the terminal may include a terminal having a first type of antenna structure. The first type of antenna structure includes one of the following: in response to the terminal operating in the frequency range FR1, the number of receiving antennas is a predetermined number; in response to the terminal operating in the frequency range FR2, the number of antenna elements included in a single antenna panel is less than a quantity threshold. Exemplarily, the predetermined number may be 1. The quantity threshold may be determined based on the antenna elements included in one antenna panel in the NR terminal. For example, the quantity threshold is the number of antenna elements included in one antenna panel in the NR terminal (non-RedCap terminal).

[0159] In one embodiment, the access network device sends configuration information to the terminal, wherein the configuration information is used to indicate: a predetermined threshold value of signal transmission quality for a terminal with a first type of antenna structure to perform SDT; the terminal determines a threshold value of signal transmission quality for the terminal to perform small data packet transmission SDT based on the configuration information. If the terminal determines that the terminal is a terminal with a first type of antenna structure and the measured signal transmission quality of the synchronization signal is greater than the predetermined threshold value, the terminal performs SDT.

[0160] In one embodiment, the access network device sends configuration information to the terminal, wherein the configuration information is used to indicate: a correction value of a reference threshold value of signal transmission quality of a terminal with a first type of antenna structure performing SDT, and the terminal determines the threshold value of signal transmission quality for the terminal to perform small data packet transmission SDT based on the configuration information. If the terminal determines that the terminal is a terminal with a first type of antenna structure and the measured signal transmission quality of the synchronization signal is greater than the reference threshold value corrected by the correction value, the terminal performs SDT. It should be noted that the reference threshold value may be a threshold value used when a non-RedCap terminal performs SDT, wherein a non-RedCap terminal may be understood as a terminal whose capability has not been reduced, such as an LTE terminal. The correction value may be an offset. Correcting the reference threshold value using the correction value may be subtracting the correction value from the reference threshold value. Here, the access network device may send the reference threshold value to the terminal (including a RedCap terminal and a non-RedCap terminal) in advance. The reference threshold value is a threshold value shared by all terminals.

[0161] It should be noted that, in one embodiment, the terminal may also use the correction value to correct the measured signal transmission quality of the synchronization signal after receiving the correction value. If the terminal determines that the terminal is a terminal of the first type of antenna structure and the corrected measured signal transmission quality of the synchronization signal is greater than the reference threshold value, SDT is executed. Here, using the correction value to correct the measured signal transmission quality of the synchronization signal may be to add the correction value on the basis of the measured signal transmission quality of the synchronization signal. It can be understood that in this embodiment, the reference threshold value is actually corrected, and compared with directly correcting the reference threshold value, it is only a change in the calculation form.

[0162] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0163] In one embodiment, the threshold value of the signal transmission quality includes a threshold value of the signal transmission quality for the terminal to perform SDT based on a predetermined transmission mode; the predetermined transmission mode includes at least one of the following:

[0164] The first method is an SDT method based on semi-static configuration;

[0165] The second method is an SDT method based on 2-step random access;

[0166] The third method is an SDT method based on 4-step random access;

[0167] Among them, the threshold value of the first mode is the first threshold value; the threshold value of the second mode is the second threshold value; the threshold value of the third mode is the third threshold value; the first threshold value is greater than the second threshold value; the second threshold value is greater than the third threshold value.

[0168] It should be noted that, for terminals with different types of antenna structures, the threshold values ​​of signal transmission quality for executing SDT configured may be different. Here, the terminal includes a terminal with a first type of antenna structure, etc. Exemplarily, the predetermined threshold values ​​of signal transmission quality for executing SDT configured for terminals with different types of antenna structures are different, or the correction values ​​of the reference thresholds of signal transmission quality for executing SDT configured for terminals with different types of antenna structures are different.

[0169] In one embodiment, the terminal may include terminals with different types of antenna structures. The first type of antenna structure includes one of the following: in response to the terminal operating in the frequency range FR1, the number of receiving antennas is a predetermined number; in response to the terminal operating in the frequency range FR2, the number of antenna elements included in a single antenna panel is less than a quantity threshold. Exemplarily, the predetermined number may be 1. The quantity threshold may be determined based on the antenna elements included in one antenna panel in the NR terminal. For example, the quantity threshold is the number of antenna elements included in one antenna panel in the NR terminal (non-RedCap terminal).

[0170] In order to better understand the embodiments of the present disclosure, the technical solution of the present disclosure is further described below through two exemplary embodiments:

[0171] Example 1

[0172] A wireless transmission method is provided, wherein the method comprises:

[0173] Step 81, the terminal obtains the RSRP threshold 1 for whether to use SDT, and uses the RSRP threshold 1 corrected by the correction value to determine whether the terminal performs SDT. If the measured RSRP exceeds the corrected RSRP threshold 1, SDT is performed. It should be noted that the measured RSRP can also be directly corrected by using the correction value, and then the corrected measured RSRP is directly compared with the RSRP threshold 1. If the corrected measured RSRP is greater than the RSRP threshold 1, SDT is performed. Here, the RSRP threshold or the measured RSRP can be corrected by using the correction value indicated by the configuration information.

[0174] Step 82: If the terminal is configured with the corresponding CG-SDT resource, the terminal obtains the RSRP threshold 2 of the CG-SDT. If the timing advance condition of the CG-SDT is met, and the terminal compares the corrected RSRP threshold 2 with the measured current RSRP, it is determined whether the terminal can use the CG-SDT. If it is met (the measured current RSRP is greater than the corrected RSRP threshold 2), the CG-SDT is used for SDT transmission. Here, the RSRP threshold 2 can be corrected using the correction value indicated by the configuration information.

[0175] Step 83: If the conditions for executing CG-SDT are not met, and if 2-step RACH SDT is configured, the terminal obtains the RSPR threshold 3 of 2-step SDT, compares the modified RSRP threshold 3 with the measured current RSRP, and if the requirements are met (the measured current RSRP is greater than the modified RSRP threshold 3), 2-step random access SDT is used for SDT transmission. Otherwise, 4-step RACH SDT random access is used. Here, RSRP threshold 3 can be modified using the correction value indicated by the configuration information.
