The embodiments of the present disclosure do not limit the implementation form of the network management device 130.
[0112] To facilitate understanding by 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 will understand that the multiple embodiments provided in the embodiments of the present disclosure can be implemented individually, or can be implemented together with the methods of other embodiments in the embodiments of the present disclosure, or can be implemented together with some methods in other related technologies individually or in combination; the embodiments of the present disclosure do not limit this.
[0113] In order to better understand the technical solutions described in any embodiment of the present disclosure, first, the application scenarios in the relevant technologies are described:
[0114] In one embodiment, a solution is proposed to support small data packet transmission (SDT) in the inactive state of Radio Resource Control (RRC). That is, the terminal can complete the small data packet transmission without entering the RRC connected state, so as to reduce the waste of time and frequency resources, shorten the data transmission delay, and save terminal energy consumption.
[0115] 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 (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 BPDU is reached, the semi-static resources configured by the base station are used to transmit small data packets.
[0116] 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 data packet size 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 data packet size limit, the terminal must also compare the current synchronization signal reference signal received power (SS-RSRP, Synchronization Signal Reference Signal Received Power) with the reference signal received power (RSRP, Reference Signal Received Power) threshold before transmitting the small data packet. For example, please refer again to 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 only be performed under good coverage conditions to avoid,waste of uplink transmission resources.
[0117] For random access-based SDT, whether to choose 2-step random access SDT or 4-step random access SDT, the RSRP threshold must also be determined. Figure 2Only when the SS-RSRP is greater than RSRP threshold 2 can the terminal use 2-step random access for SDT. Otherwise, 4-step random access is used. The RSRP threshold determination here is used to determine whether the terminal is located in the cell center. Only when the terminal is close to the base station and the cyclic prefix (CP) can compensate for the TA size can the terminal use 2-step random access for SDT. Here, the aforementioned threshold 1 must be less than threshold 2.
[0118] In one embodiment, a physical uplink shared channel retransmission type A (PUSCH repetition type A) mode is introduced into the transmission of the third message msg3 to enhance the signal coverage of the third message msg3.
[0119] In one embodiment, a single RSRP threshold is used to determine whether to perform SDT transmission for all terminals. However, with the introduction of Coverage Enhancement (CE) functionality, it is hoped that SDT can be used even for terminals with poor coverage at the cell edge to reduce power consumption and resource overhead, while also reducing data transmission latency.
[0120] The related art does not take into account the impact of CE factors. For terminals using random access to perform SDT, only a single RSRP threshold is used. If this single threshold is used for all terminals (both those supporting CE and those not supporting CE), it will exclude terminals with CE capabilities from using SDT at the cell edge.
[0121] In one embodiment, coverage enhancement is achieved through MSG3 repetition type A. The introduction of MSG3 repetition type A enables MSG3 inter-slot frequency hopping (inter-slot FH). This mechanism can achieve frequency diversity gain, making MSG3 inter-slot FH a key area of focus. Specifically, configuring inter-slot FH parameters for MSG3 is a key concern.
[0122] like Figure 3 As shown, this embodiment provides a wireless transmission method, wherein the method is performed by a terminal and includes:
[0123] Step 31: Determine a threshold value of signal transmission quality for the terminal to perform small data packet transmission (SDT) based on the configuration information;
[0124] The configuration information indicates: in a network supporting coverage enhanced CE, a threshold value for executing SDT for at least one type of terminal among terminals supporting CE and terminals not supporting CE.
[0125] 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 sensor device, and / or a medical device. In some embodiments, the terminal may be a RedCap terminal or a predetermined version of a new radio (NR) terminal (e.g., an R17 NR terminal). It should be noted that the RedCap terminal may be an enhanced eRedCap terminal.
[0126] The access network equipment involved in the present disclosure may be various types of base stations, for example, base stations of the fifth generation mobile communication (5G) network or other evolved base stations.
[0127] In one embodiment, a signal transmission quality threshold for a terminal to perform small data packet transmission (SDT) is determined based on configuration information. The configuration information indicates, in a network supporting coverage enhancement (CE), a threshold for performing SDT on at least one type of terminal, either a CE-supporting terminal or a CE-non-CE-supporting terminal. The threshold for performing SDT on a CE-supporting terminal is lower than a threshold for performing SDT on a CE-non-CE-supporting terminal. It is understood that the SDT thresholds can be configured separately for CE-supporting terminals and non-CE-supporting terminals, and the thresholds for performing SDT can be different.
[0128] In one scenario embodiment, before determining whether to perform SDT, the terminal may obtain the signal transmission quality (e.g., RSRP) 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 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 signal transmission quality is not limited to the above parameters.
[0129] 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 a data packet can be determined based on the number of bits in the information field occupied by the data packet during transmission. For example, if the number of bits in the information field occupied by the data packet during transmission is less than a threshold, the data packet is determined to be a small data packet.
[0130] In one embodiment, SDT is performed in response to the measured signal transmission quality of the synchronization signal being greater than a 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. 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.
[0131] It should be noted that there may be multiple threshold values for the signal transmission quality used by 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 values may include an A threshold value, a B threshold value, and a C threshold value, wherein the C threshold value is less than the B threshold value, and the B threshold value is less than the A threshold value. If the measured signal transmission quality of the synchronization signal is greater than the C threshold value and less than the B 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 B threshold value and less than the A 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 A threshold value, the third transmission mode is used to perform SDT. 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.
[0132] It should be noted that the signal transmission quality thresholds for executing SDT may be configured differently for terminals that support CE and terminals that do not support CE. For example, the signal transmission quality threshold for executing SDT configured for terminals that support CE is a first threshold; the signal transmission quality threshold for executing SDT configured for terminals that do not support CE is a second threshold; wherein the first threshold is less than the second threshold.
[0133] In one embodiment, the network supporting CE includes a network supporting the use of repetition to transmit uplink data channels during the SDT process. The repetition here may be repeated sending and / or repeated receiving.
[0134] In one embodiment, the terminal supporting CE includes a network that at least supports the use of a repeated transmission mode to transmit an uplink data channel. Exemplarily, the terminal supporting CE is a terminal that performs coverage enhancement through msg3 repetition type A.
[0135] In one embodiment, the configuration information indicates at least one of the following:
[0136] In a network supporting CE, a first threshold value of signal transmission quality for performing SDT in a random access SDT manner by a terminal supporting CE;
[0137] In a network supporting CE, a second threshold value of signal transmission quality for performing SDT based on random access SDT by a terminal that does not support CE; 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 terminal not supporting CE to perform SDT based on the semi-statically configured SDT method.
[0227] It should be noted that those skilled in the art will understand that the method provided in the embodiments of the present disclosure may be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.
[0228] like Figure 10 As shown, this embodiment provides a wireless transmission method, wherein the method is performed by an access network device, and the method includes:
[0229] Step 101: Send configuration information to the terminal;
[0230] The configuration information indicates: in a network supporting coverage enhanced CE, at least one type of terminal among terminals supporting CE and terminals not supporting CE executes the threshold value of the SDT.
[0231] 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 sensor device, and / or a medical device. In some embodiments, the terminal may be a RedCap terminal or a predetermined version of a new radio (NR) terminal (e.g., an R17 NR terminal). It should be noted that the RedCap terminal may be an enhanced eRedCap terminal.
[0232] The access network equipment involved in the present disclosure may be various types of base stations, for example, base stations of the fifth generation mobile communication (5G) network or other evolved base stations.
[0233] In one scenario embodiment, before determining whether to perform SDT, the terminal may obtain the signal transmission quality (e.g., RSRP) of the synchronization signal and compare the signal transmission quality with the threshold value of the signal transmission quality. The terminal will only perform SDT when 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), Received Signal Strength Indicator (RSSI), Reference Signal Received Quality (RSRQ), and Signal to Interference plus Noise Ratio (SINR).
[0234] 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 a data packet can be determined based on the number of bits in the information field occupied by the data packet during transmission. For example, if the number of bits in the information field occupied by the data packet during transmission is less than a threshold, the data packet is determined to be a small data packet.
[0235] In one embodiment, in response to the measured signal transmission quality of the synchronization signal being greater than a threshold value of the signal transmission quality for the terminal to perform SDT and the size of the data packet to be transmitted being smaller than a predetermined threshold, the terminal performs SDT.
[0236] It should be noted that there may be multiple threshold values for the signal transmission quality used by the terminal to perform SDT. The access network device may send configuration information indicating the multiple threshold values to the terminal. The multiple threshold values may be used by the terminal to determine whether to use the corresponding transmission mode to perform SDT. Exemplarily, the threshold values may include an A threshold value, a B threshold value, and a C threshold value, wherein the C threshold value is less than the B threshold value, and the B threshold value is less than the A threshold value. If the measured signal transmission quality of the synchronization signal is greater than the C threshold value and less than the B threshold value, SDT is performed using the first transmission mode; or, if the measured signal transmission quality of the synchronization signal is greater than the B threshold value and less than the A threshold value, SDT is performed using the second transmission mode; or, if the measured signal transmission quality of the synchronization signal is greater than the A threshold value, SDT is performed using the third transmission mode. 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.
[0237] It should be noted that the signal transmission quality thresholds for executing SDT may be configured differently for terminals that support CE and terminals that do not support CE.

[0272] It should be noted that those skilled in the art will understand that the method provided in the embodiments of the present disclosure may be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.
[0273] 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:
[0274] Example 1
[0275] like Figure 11 As shown, this embodiment provides a wireless transmission method, wherein the method includes:
[0276] Step 111: When the network supports coverage enhancement in an SDT scenario, different thresholds for using SDT are configured for terminals with coverage enhancement capability and terminals without coverage enhancement capability.
[0277] Step 112: The network configures different SDT execution thresholds for rel-16UE and rel-17CE UE respectively through RMSI, MIB, RRC, OSI, DCI or MAC CE signaling. The SDT threshold 1 of rel-17CE UE is smaller than the SDT threshold 2 of rel-16UE.
[0278] Step 113: When the SS-RSRP measured by the CE terminal is greater than the threshold value 1, the 4-step random access method can be used to perform SDT.
[0279] Please note that, see Figure 12 When the measured SS-RSRP is less than a threshold of 3, SDT needs to enable repetition. Otherwise, repetition is disabled. Threshold 3 may be 2, which is the threshold for enabling SDT for rel-16 UEs. Alternatively, threshold 3 may be greater than 2, which is the threshold for enabling SDT for rel-16 UEs. It should be noted that the thresholds may be fixed by the protocol.
[0280] It should be noted that the transmission of group A or group B msg3 can also follow the same SDT concept as in this disclosure. In one embodiment, when the size of msg3 is greater than 56 bits and the RSRP measured by the terminal is less than a predetermined threshold, random access is initiated using the preamble resources in group B. Otherwise, random access is initiated using the preamble resources in group A. Therefore, for rel-17CE UEs, it is also possible to support lowering the RSRP threshold for selecting group A and group B during random access.
