[0102] Please refer to Figure 1 , which shows a schematic structural diagram of a wireless communication system provided by the embodiments of the present disclosure. As Figure 1 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.

[0111] For the convenience of those skilled in the art to understand, the embodiments of the present disclosure list multiple implementation manners 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 alone, or can be executed together after being combined with the methods of other embodiments in the embodiments of the present disclosure, or can be executed alone or in combination with some methods in other related technologies; the embodiments of the present disclosure do not make any limitations on this.

[0112] To better understand the technical solutions described in any embodiment of the present disclosure, first, the application scenarios in the related art are described:

[0113] In one embodiment, a solution for supporting Small Data Transmission (SDT) in the Radio Resource Control (RRC) inactive state is proposed. That is to say, the terminal can complete small data packet transmission without entering the RRC connected state, so as to reduce the waste of time-frequency resources, shorten the data transmission delay, and save the terminal energy consumption at the same time.

[0114] In one embodiment, small data packet transmission supports two methods: SDT based on the random access procedure and SDT based on semi-static configuration (CG, Configured Grant). Among them, for the SDT based on semi-static configuration, when the base station transitions from the RRC connected state to the RRC inactive state, it carries in the RRC resume or release message the semi-static time-frequency resource allocation information required for SDT transmission, as well as information such as the timing advance TA (TA, Timing Advance). When the terminal has uplink data to transmit in the RRC inactive state, it first judges the validity of the TA and the size of the data packet. When the threshold (exemplarily, please refer to Figure 2 the threshold 3 therein) is met, it uses the semi-static resources configured by the base station to transmit small data packets.

[0115] In one embodiment, the SDT based on the random access procedure is further divided into two methods, namely SDT based on 2-step random access and SDT based on 4-step random access. Among them, for the SDT based on 2-step random access, small data packets are transmitted in the physical uplink shared channel (PUSCH, Physical Uplink ShareChannel) resources of the random access message A (msgA); while for the SDT based on 4-step random access, small data packets are 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 small data packets be transmitted during the random access procedure. Otherwise, it is necessary to enter the connected state through the random access procedure and then transmit small data packets. In addition to the limitation of the data packet size, the terminal also needs to 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 small data packets. Exemplarily, please refer to Figure 2 again. Only when the current SS-RSRP is greater than the RSRP threshold 1 will small data packets be transmitted. The purpose of the RSRP threshold comparison here is to ensure that SDT transmission can only be carried out under good coverage conditions to avoid wasting uplink transmission resources.

[0116] For the SDT based on random access, when choosing between 2-step random access SDT and 4-step random access SDT, it is also necessary to judge the RSRP threshold. That is to say, please refer to Figure 2, only when the SS-RSRP is greater than the RSRP threshold 2 can the terminal use the 2-step random access method for SDT; otherwise, it uses the 4-step random access method for SDT. The purpose of performing the RSRP threshold judgment here is to determine whether the terminal is located at the cell center. Only when the terminal is relatively close to the base station and the cyclic prefix (CP) can compensate for the size of the TA can the terminal use the 2-step random access method for SDT. Here, the above-mentioned threshold 1 is less than threshold 2.

[0117] In one embodiment, a method of introducing physical uplink shared channel retransmission type A (PUSCH repetition type A) for the transmission of the third message msg3 is adopted to enhance the signal coverage of the third message msg3.

[0118] In one embodiment, for all terminals, only a single RSRP threshold is used to determine whether to perform SDT transmission. However, due to the introduction of the coverage enhancement (CE) function, it is hoped that even terminals with poor coverage at the cell edge can use SDT to reduce power consumption and resource overhead, and at the same time reduce data transmission delay.

[0119] In the related art, the influence of the CE factor is not considered. Only a single RSRP threshold is used for the terminal to use random access for SDT. If this single threshold is used for all terminals (supporting CE and not supporting CE), terminals with CE capabilities will be excluded from using SDT at the cell edge.

[0120] In one embodiment, coverage enhancement is performed through msg3 repetition type A. Among them, after introducing msg3 repetition type A, it makes inter-slot frequency hopping (inter-slot FH) of the msg3 time slot possible. Through the msg3 inter-slot FH mechanism, frequency diversity gain can be obtained. Therefore, msg3 inter-slot FH has become the focus of attention. Specifically, how to configure the inter-slot FH related parameters for msg3 has become the key issue of concern.

[0121] As Figure 3 shown, in this embodiment, a method for wireless transmission is provided. Among them, the method is executed by a terminal, and the method includes:

[0122] Step 31: Based on the configuration information, determine the threshold value of the signal transmission quality for the terminal to perform small packet transmission SDT;

[0123] Among them, the configuration information indicates: in a network that supports coverage enhancement CE, the threshold for at least one type of terminal among the terminals that support CE and the terminals that do not support CE to perform SDT.

[0124] 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 roadside unit (RSU), a smart home terminal, an industrial sensing device, and / or a medical device, etc. In some embodiments, the terminal may be a RedCap terminal or a new radio (NR) terminal of a predetermined version (for example, an NR terminal of R17). It should be noted that the RedCap terminal may be an enhanced eRedCap terminal.

[0125] The access network device involved in the present disclosure may be various types of base stations, for example, a base station of a fifth-generation mobile communication (5G) network or other evolved base stations.

[0126] In one embodiment, based on the configuration information, a threshold for the signal transmission quality for a terminal to perform small data packet transmission (SDT) is determined; among them, the configuration information indicates: in a network that supports coverage enhancement CE, the threshold for at least one type of terminal among the terminals that support CE and the terminals that do not support CE to perform SDT; among them, the threshold for a terminal that supports CE to perform SDT is less than the threshold for a terminal that does not support CE to perform SDT. It can be understood that the thresholds for a terminal that supports CE and a terminal that does not support CE to perform SDT can be configured separately, and the two thresholds can be different.

[0127] In a scenario embodiment, before determining whether to perform SDT, the terminal may obtain the signal transmission quality of the synchronization signal (for example, RSRP), and compare the signal transmission quality with the threshold of the signal transmission quality. Only when it is determined that the signal transmission quality is greater than the threshold will SDT be performed, otherwise SDT will not be performed. In this way, waste of resources can be reduced. Here, the signal transmission quality is used to indicate the transmission quality of the signal, and can be determined by at least one of the following parameters: reference signal receiving power (RSRP), received signal strength indicator (RSSI), reference signal receiving quality (RSRQ), and signal to interference plus noise ratio (SINR). It should be noted that the determination of the signal transmission quality is not limited to the above parameters.

[0128] The small data packet in the present disclosure may be a data packet whose size or dimension (SIZE) is less than a predetermined threshold. Wherein, the size or dimension of the data packet may be determined according to the number of bits of the information field occupied by the data packet during transmission. Exemplarily, when the number of bits of the information field occupied by the data packet during transmission is less than the quantity threshold, the data packet is determined to be a small data packet.

[0129] In one embodiment, in response to the signal transmission quality of the measured 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 in the embodiments of the present disclosure, "less than" has the meaning of "less than or equal to" in some scenarios, and "greater than" has the meaning of "greater than or equal to" in some scenarios.

[0130] It should be noted that there may be multiple threshold values for the signal transmission quality for the terminal to perform SDT. These multiple threshold values can be used to determine to perform SDT using the corresponding transmission method. Exemplarily, the threshold value may include threshold value A, threshold value B, and threshold value C, where threshold value C is less than threshold value B, and threshold value B is less than threshold value A. If the signal transmission quality of the measured synchronization signal is greater than threshold value C and less than threshold value B, SDT is performed using the first transmission method; or, if the signal transmission quality of the measured synchronization signal is greater than threshold value B and less than threshold value A, SDT is performed using the second transmission method; or, if the signal transmission quality of the measured synchronization signal is greater than threshold value A, SDT is performed using the third transmission method. Wherein, the first transmission method may be an SDT method based on 4-step random access, the second transmission method may be an SDT method based on 2-step random access, and the third transmission method may be an SDT method based on semi-static configuration.

[0131] It should be noted that for terminals supporting CE and terminals not supporting CE, the configured threshold values of the signal transmission quality for performing SDT may be different. Exemplarily, the threshold value of the signal transmission quality for performing SDT configured for terminals supporting CE is the first threshold value; the threshold value of the signal transmission quality for performing SDT configured for terminals not supporting CE is the second threshold value; where the first threshold value is less than the second threshold value.

[0132] In one embodiment, a network supporting CE includes a network that supports using the repetition (Repetition) method to transmit the uplink data channel during the SDT process. Here, the repetition transmission may be repeated sending and / or repeated receiving.

[0133] In one embodiment, a CE - supported terminal includes a network that at least supports transmitting an uplink data channel using a repeated - transmission method. Exemplarily, the CE - supported terminal is a terminal with coverage enhancement through msg3 repetition type A.

[0134] In one embodiment, the configuration information indicates at least one of the following:

[0135] In a CE - supported network, a CE - supported terminal performs a first threshold value of the signal transmission quality of SDT based on the SDT method of random access;

[0136] In a CE - supported network, a non - CE - supported terminal performs a second threshold value of the signal transmission quality of SDT based on the SDT method of random access; wherein, the first threshold value is less than the second threshold value;

Here, the seventh threshold value is greater than or equal to the threshold value for signal transmission quality for a non-CE-supported terminal to perform SDT in the SDT mode based on semi-static configuration.

[0226] 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.

[0227] As Figure 10 shown, a method for wireless transmission is provided in this embodiment. Among them, this method is executed by an access network device, and this method includes:

[0228] Step 101: Send configuration information to the terminal;

[0229] Wherein, the configuration information indicates: in a network supporting coverage enhancement (CE), the threshold value for at least one type of terminal among CE-supported terminals and non-CE-supported terminals to perform the SDT.

[0230] Here, the terminal involved in the present disclosure can be, but is not limited to, a mobile phone, a wearable device, a vehicle-mounted terminal, a roadside unit (RSU), a smart home terminal, an industrial sensing device, and / or a medical device, etc. In some embodiments, the terminal can be a RedCap terminal or a new radio (NR) terminal of a predetermined version (for example, an NR terminal of R17). It should be noted that the RedCap terminal can be an enhanced eRedCap terminal.

[0231] The access network device involved in the present disclosure can be various types of base stations, for example, a base station in a fifth-generation mobile communication (5G) network or other evolved base stations.

[0232] In a scenario embodiment, before determining whether to perform SDT, the terminal may obtain the signal transmission quality of the synchronization signal (e.g., RSRP), and compare the signal transmission quality with a threshold of the signal transmission quality. Only when it is determined that the signal transmission quality is greater than the threshold, will the terminal perform SDT; otherwise, the terminal will not perform SDT. In this way, resource waste can be reduced. Here, the signal transmission quality is used to indicate the transmission quality of the signal, and can be determined by at least one of the following parameters: Reference Signal Receiving Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Signal Receiving Quality (RSRQ), and Signal to Interference plus Noise Ratio (SINR).

[0233] The small data packet in the present disclosure may be a data packet whose size or dimension (SIZE) is less than a predetermined threshold. Among them, the size or dimension of the data packet can be determined according to the number of bits of the information field occupied by the data packet during transmission. Exemplarily, when the number of bits of the information field occupied by the data packet during transmission is less than the quantity threshold, the data packet is determined to be a small data packet.

[0234] In an embodiment, in response to the signal transmission quality of the measured synchronization signal being greater than the threshold of the 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, the terminal performs SDT.

[0235] It should be noted that there may be multiple thresholds of the signal transmission quality for the terminal to perform SDT. The access network device may send configuration information indicating the multiple thresholds to the terminal. The multiple thresholds can be used for the terminal to determine to perform SDT using the corresponding transmission mode. Exemplarily, the threshold may include threshold A, threshold B, and threshold C, where threshold C is less than threshold B, and threshold B is less than threshold A. If the signal transmission quality of the measured synchronization signal is greater than threshold C and less than threshold B, SDT is performed using the first transmission mode; or, if the signal transmission quality of the measured synchronization signal is greater than threshold B and less than threshold A, SDT is performed using the second transmission mode; or, if the signal transmission quality of the measured synchronization signal is greater than threshold A, SDT is performed using the third transmission mode.

[0271] 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.

[0272] To better understand the embodiments of the present disclosure, the technical solutions of the present disclosure are further described below through two exemplary embodiments:

[0273] Example 1

[0274] As Figure 11 shown, a method for wireless transmission is provided in this embodiment, where the method includes:

[0275] Step 111, when the network supports using coverage enhancement in the SDT scenario, different thresholds for using SDT are configured for a terminal with coverage enhancement capability and a terminal without coverage enhancement capability respectively.

[0276] Step 112, the network configures different thresholds for performing SDT for rel-16UE and rel-17CE UE respectively through signaling such as RMSI, MIB, RRC, OSI, DCI or MAC CE, where the threshold 1 for rel-17CE UE SDT is less than the threshold 2 for rel-16UE.

[0277] Step 113: When the SS-RSRP measured by the CE terminal is greater than threshold 1, the 4-step random access method can be used to perform SDT.

[0278] It should be noted that, please refer to Figure 12 , when the measured SS-RSRP is less than threshold 3, SDT needs to enable the retransmission function (repetition), otherwise, the retransmission function is not enabled. Among them, the value of threshold 3 can be the threshold 2 for rel-16 UEs to enable SDT. Or, the value of threshold 3 can be greater than the threshold 2 for rel-16 UEs to enable SDT. It should be noted that the above threshold values can be specified as fixed values by the protocol.

[0279] It should be noted that for the transmission based on group A or group B msg3, the same concept of SDT in this disclosure can also be followed. In one embodiment, when the size of msg3 is greater than 56 bits and the RSRP measured by the terminal is less than the predetermined threshold, the preamble resource in group B is used to initiate random access, otherwise, the preamble resource in group A is used for random access. Therefore, for rel-17 CE UEs, it is also possible to support reducing the RSRP thresholds for selecting group A and group B in the random access process.
