A Small Data Packet Transmission (SDT) Method and Apparatus

Abstract

This disclosure provides a Small Data Packet Transmission (SDT) method and apparatus. In response to the eRedCap terminal supporting SDT transmission, a first threshold is determined, and whether SDT transmission should be performed is determined based on the first threshold. Alternatively, in response to the eRedCap terminal not supporting SDT transmission, a Random Access RACH procedure is triggered, and the terminal enters a connected state. An independent SDT transmission threshold is introduced for the eRedCap terminal to avoid impacting SDT transmission on non-eRedCap terminals with non-enhanced capabilities, while ensuring reasonable scheduling of the eRedCap terminal.

Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a Small Data Packet Transmission (SDT) method and apparatus. Background Technology

[0002] When the network side is configured to allow enhanced reduced capability (eRedCap) terminals to support small data transmission (SDT), if an inactive terminal generates an uplink data packet, it first checks whether the data volume meets the sdt-dataVolume threshold and whether the reference signal receiving power (RSRP) meets the RSRP threshold. If it is determined that the data volume is less than the sdt-dataVolume threshold and the measured RSRP is greater than the RSRP threshold, the terminal will initiate SDT transmission.

[0003] For the transmission of message 3 (Msg3) in the inactive state, due to the lack of reference signal (RS) measurement, it is impossible to obtain accurate link quality status. When scheduling Msg3, the base station usually uses a relatively conservative modulation and coding scheme (MCS). In this scenario, if the data volume threshold is configured relatively large and the data volume of the eRedCap terminal is relatively large, the eRedCap terminal can only divide the payload into multiple transport blocks (TB) for transmission. This results in relatively large power consumption of the eRedCap terminal and overall payload transmission delay, failing to achieve the goal of reducing power consumption through SDT transmission in the inactive state. Summary of the Invention

The same or similar elements are shown. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0157] To better understand the Small Data Packet Transmission (SDT) method disclosed in this disclosure, the communication system to which this disclosure is applicable will be described first.

[0158] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided in this disclosure. The communication system may include, but is not limited to, a network device and a terminal device, wherein the terminal device communicates with the network device. Figure 1 The number and form of the devices shown are for illustrative purposes only and do not constitute a limitation of this disclosure. In actual applications, they may include two or more network devices or two or more terminal devices. Figure 1 The communication system shown includes a network device 101 and a terminal device 102.

[0159] As an example, a terminal device can function as either an eRedCap terminal or a non-eRedCap terminal.

[0160] It should be noted that the technical solutions of this disclosure can be applied to various communication systems. For example, Long Term Evolution (LTE) systems, 5th Generation (5G) mobile communication systems, 5G New Radio (NR) systems, or other future new mobile communication systems.

[0161] The network device in this disclosure is an entity on the network side used to transmit or receive signals. For example, network device 101 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. This disclosure does not limit the specific technology or device form used in the network device. The network device provided in this disclosure can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. Using a CU-DU structure, the protocol layer of a network device, such as a base station, can be separated. Some protocol layer functions are centrally controlled by the CU, while the remaining part or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0162] The terminal device in this disclosure is a user-side entity used to receive or transmit signals, such as a mobile phone. The terminal device can also be called a terminal, mobile station (MS), mobile terminal (MT), etc. Terminal devices can be communication-enabled vehicles, smart cars, mobile phones, wearable devices, tablets, computers with wireless transceiver capabilities, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminal devices in industrial control, wireless terminal devices in self-driving, wireless terminal devices in remote medical surgery, wireless terminal devices in smart grids, wireless terminal devices in transportation safety, wireless terminal devices in smart cities, wireless terminal devices in smart homes, and so on. This disclosure does not limit the specific technology or device form used in the terminal device.

[0163] Because accurate link quality status cannot be obtained in the inactive state, base stations typically use a conservative modulation and coding scheme (MCS) when scheduling message 3Msg3. In this scenario, if the data volume threshold is set relatively high, and the eRedCap terminal's data volume threshold is also relatively high, the eRedCap terminal can only transmit the payload in multiple transport blocks (TBs), resulting in high power consumption for the eRedCap terminal and high overall payload transmission latency. This fails to achieve the goal of reducing power consumption through SDT transmission in the inactive state. If the eRedCap terminal's data volume threshold is relatively low, the eRedCap terminal will enter the connected state. Therefore, how to set a data volume threshold for the eRedCap terminal is a problem that urgently needs to be solved.

[0164] To address the aforementioned issues, this disclosure proposes a Small Data Packet Transmission (SDT) method and apparatus.

[0165] Please see Figure 2 , Figure 2 This is a flowchart illustrating a Small Data Packet Transmission (SDT) method provided in an embodiment of this disclosure. Figure 2 As shown, the method is executed by the enhanced degraded capability eRedCap terminal, and the method may include, but is not limited to, the following steps:

[0166] Step S201: In response to the fact that the eRedCap terminal supports SDT transmission, determine a first threshold, and determine whether to perform SDT transmission based on the first threshold.

[0167] If it is determined that the eRedCap terminal supports SDT transmission, a first threshold is established. If an inactive eRedCap terminal receives an uplink data packet, the decision to perform SDT transmission is made based on this first threshold. In practical applications, the inactive state indicates that the eRedCap terminal is inactive.

[0168] After the eRedCap terminal determines the first threshold, this first threshold is used to determine whether to perform SDT transmission. When it is less than or equal to the first threshold, SDT transmission is performed; when it is greater than the first threshold, SDT transmission is not performed. Step S202: In response to the fact that the eRedCap terminal does not support SDT transmission, a Random Access Channel (RACH) procedure is triggered, and the terminal enters the connected state.

[0169] If the eRedCap terminal supports SDT transmission, the eRedCap terminal will trigger the RACH procedure to enter the connected state. Considering that the connected state requires relatively accurate RS measurement, a more accurate MCS can be used in this case. For example, a relatively high MCS can be used to minimize payload segmentation, thereby reducing power consumption and shortening the overall transmission latency.

[0170] It should be noted that the embodiments of this disclosure may include multiple steps (step S201 and step S202). For ease of description, these steps are numbered, but these numbers are not limitations on the execution time slots or execution order between the steps. Rather, they are executed separately under different conditions or different scenarios.

[0171] For details on how to trigger the RACH procedure and enter the connected state, please refer to any relevant technical descriptions; this disclosure will not elaborate further.

[0172] In summary, after determining that it supports SDT transmission, the eRedCap terminal determines a first threshold and decides whether to perform SDT transmission based on the first threshold. By introducing an independent SDT transmission threshold for the eRedCap terminal, reasonable scheduling of the eRedCap terminal can be ensured. Alternatively, after determining that the eRedCap terminal does not support SDT transmission, the RACH procedure is triggered to enter the connected state to avoid affecting the SDT transmission of non-eRedCap terminals.

[0173] In this embodiment of the disclosure, the determination of the first threshold can be based on a second threshold, which is a threshold applied to non-eRedCap terminals with non-enhanced capability reduction. Alternatively, the threshold can be determined without being based on the second threshold. Specific embodiments of this disclosure do not limit this. The first threshold can be the same as or different from the second threshold. In specific implementation, it can be set according to the actual situation, and embodiments of this disclosure do not limit this.

[0174] The first threshold is determined by the eRedCap terminal, and the second threshold is determined by the non-eRedCap terminal (also known as a traditional normal terminal). In practical applications, when the second threshold is less than or equal to the maximum TBS processing capacity of the eRedCap terminal, the first threshold is the same as the second threshold; when the second threshold is greater than the maximum TBS processing capacity of the eRedCap terminal, the first threshold is different from the second threshold. This configuration will not affect the SDT transmission of the non-eRedCap terminal, while ensuring reasonable scheduling of the eRedCap terminal, thus achieving the goal of reducing power consumption through SDT transmission.

[0175] Alternatively, the first threshold is the same as the second threshold, meaning that the base station configures the same threshold for both non-eRedCap and eRedCap terminals.

[0176] The first threshold includes at least one of the following: a first data volume threshold and a first reference signal received power (RSRP) threshold; the second threshold includes at least one of the following: a second data volume threshold and a second RSRP threshold; in this embodiment of the disclosure, the first threshold and the second threshold may be the same or different, and the first threshold and the second threshold are independent of each other. This embodiment of the disclosure does not limit the magnitude of the first threshold and the second threshold. The first threshold is a first threshold determined by the eRedCap terminal, and the second threshold is a second threshold determined by the non-eRedCap terminal (also known as a traditional normal terminal).

[0177] When determining the first threshold, it can be determined by the eRedCap terminal through calculation, or it can be configured by the network device for the eRedCap terminal. In certain scenarios, the second threshold can also be determined as the first threshold, that is, the first threshold and the second threshold are equal. The embodiments disclosed herein do not limit which method is used in a specific implementation. For details, please refer to the following specific description.

[0178] This disclosure provides a method for determining a first threshold. Figure 3 This is a flowchart illustrating a method for determining a first threshold provided in an embodiment of this disclosure. The Small Data Packet Transmission (SDT) method can be executed alone, or it can be executed together with any embodiment of this disclosure or any possible implementation thereof, or it can be executed together with any technical solution in related technologies.

[0179] like Figure 3 As shown, the method for determining the first threshold may include the following steps:

[0180] Step S301: Determine the first threshold by calculation.

[0181] When determining the first threshold through calculation, different processing methods can be performed for different scenarios, as follows:

[0182] Scenario 1: When the eRedCap terminal supports SDT transmission, the eRedCap terminal does not make any judgments and determines the first threshold through calculation. This first threshold is used to limit whether the conditions for executing SDT transmission are met. In this scenario, when calculating and determining the first threshold, the second threshold is not considered. That is, regardless of whether the second data volume threshold is greater than or less than or equal to the eRedCap terminal's maximum TBS processing capacity, the independent configuration of the first threshold is executed after the eRedCap terminal supports SDT transmission.

[0183] Scenario 2: When the eRedCap terminal supports SDT transmission, the eRedCap terminal first compares a second threshold with its maximum TBS processing capacity. If the second threshold is greater than the eRedCap terminal's maximum TBS processing capacity, a first threshold is calculated. It's important to note that Scenario 2 differs from Scenario 1 in that the eRedCap terminal only determines the first threshold if the second threshold is greater than its maximum TBS processing capacity; otherwise, it doesn't. In summary, after determining that it supports SDT transmission, the eRedCap terminal calculates the first threshold and then determines whether to perform SDT transmission based on it. By introducing an independent SDT transmission threshold for the eRedCap terminal, reasonable scheduling of the eRedCap terminal can be ensured.

[0184] As can be seen from the above embodiments, the first threshold includes at least one of the following: a first data volume threshold and a first RSRP threshold. When the contents included in the first threshold differ, the method of determining the first threshold may also be different. Specifically:

[0185] Method 1: When the first threshold includes the first data volume threshold, the first threshold is determined by calculation, such as... Figure 4 As shown, Figure 4 A flowchart illustrating a method for calculating and determining a first threshold provided in this disclosure includes:

[0186] Step S401: Obtain a first adjustment parameter and a second data volume threshold; wherein the first adjustment parameter includes any one of the following: coefficient or offset.

[0187] The first adjustment parameter and the second data volume threshold described in this disclosure are both configured by the base station and sent to the eRedCap terminal. For example, the first adjustment parameter is a coefficient (e.g., represented by alpha), and its value is less than or equal to 1. For example, the first adjustment parameter alpha can be configured by the network device (e.g., the base station) to 1, 0.8, or 0.6, etc., and the specific value is not limited.

[0188] The first adjustment parameter is the offset (e.g., represented by offset). As one possible implementation method of this disclosure, the offset is the offset relative to the non-eRedCap terminal. It can be set according to business needs, and there is no specific limitation.

[0189] It should be noted that the coefficients and offsets described in this disclosure are all configurable fixed values, or the coefficients or offsets may also be fixed values ​​specified in the protocol.

[0190] Step S402: Calculate and determine the first data volume threshold based on the first adjustment parameter, the second data volume threshold, and the maximum TBS processing capability of the eRedCap terminal.

[0191] When determining the first data volume threshold, the maximum processing capacity of the eRedCap terminal's TBS should be taken into account. The purpose is to prevent the determined first threshold from exceeding the maximum processing capacity of the eRedCap terminal's TBS, which would cause problems such as high power consumption and large overall payload transmission latency of the eRedCap terminal.

[0192] As a possible approach of this disclosure, when calculating and determining the first data volume threshold based on the first adjustment parameter, the second data volume threshold, and the maximum TBS processing capability of the eRedCap terminal, the eRedCap terminal can calculate and determine the first data volume threshold based on the first adjustment parameter, the second data volume threshold, and the maximum TBS processing capability of the eRedCap terminal through the first data volume threshold calculation rules between the eRedCap terminal and the network device.

[0193] As another feasible approach of this disclosure, the calculation rule for the first data volume threshold can be configured by the network device or agreed upon by the protocol, and this disclosure does not impose any restrictions.

[0194] This disclosure provides a method for obtaining a first adjustment parameter. This method can be executed alone, or it can be executed in conjunction with any embodiment of this disclosure or possible implementations within the embodiments, or it can be executed in conjunction with any technical solution in related technologies. As one possible implementation of this disclosure, the first adjustment parameter is obtained according to a protocol agreement. As another possible implementation of this disclosure, the first adjustment parameter is configured in a network device.

[0195] In summary, after determining that it supports SDT transmission, the eRedCap terminal, when the first threshold includes a first data volume threshold, obtains a first adjustment parameter and a second data volume threshold. The first adjustment parameter includes any one of the following: a coefficient or an offset. The first data volume threshold is calculated based on the first adjustment parameter, the second data volume threshold, and the eRedCap terminal's maximum TBS processing capacity. Whether to perform SDT transmission is determined based on the first data volume threshold. By introducing an independent first data volume threshold for SDT transmission to the eRedCap terminal, reasonable scheduling of the eRedCap terminal can be ensured. If it is determined that the eRedCap terminal does not support SDT transmission, the RACH procedure is triggered, and the terminal enters the connected state to avoid affecting SDT transmission on non-eRedCap terminals.

[0196] As a feasible approach of this disclosure, the determination of the first data volume threshold based on the first adjustment parameter, the second data volume threshold, and the maximum TBS processing capacity of the eRedCap terminal includes the following methods:

[0197] (1) The first data volume threshold is determined by calculating the smaller of the second data volume threshold and the maximum TBS processing capability of the eRedCap terminal with the first adjustment coefficient. For the eRedCap terminal, the first data volume threshold can be calculated as follows: alpha1*min{datavolume threshold for non-eRedCap terminal, the maximum TBS supported by eRedCap}, where alpha1 is the first adjustment coefficient, which can be indicated / configured by the base station or given a specific value by the protocol, datavolume threshold for non-eRedCap terminal is the second data volume threshold, and the maximum TBS supported by eRedCap is the maximum TBS processing capability of the eRedCap terminal.

[0198] (2) The first data volume threshold is determined by calculating the second data volume threshold with the first adjustment parameter. For eRedCap terminals, the first data volume threshold can be calculated as follows: alpha * data volume threshold for non-eRedCap terminals, or data volume threshold for non-eRedCap terminals - offset, where offset is the first adjustment parameter (first adjustment offset), and offset1 can be indicated / configured by the base station or given a specific value by the protocol.

[0199] (3) The first data volume threshold is determined by calculating the maximum TBS processing capacity of the eRedCap terminal with the first adjustment parameter. For the eRedCap terminal, the first data volume threshold can be calculated as follows: alpha * the maximum TBS supported by eRedCap.

[0200] In the above methods (1) to (3), when the eRedCap terminal determines the first data volume threshold, any method can be selected according to the business needs of the eRedCap terminal. In particular, this disclosure does not limit this.

[0201] In summary, Method 1 determines an independent first threshold for the eRedCap terminal.

[0202] Method 2: When the first threshold includes a data volume threshold, the first threshold is determined by calculation. Please refer to [link to relevant documentation]. Figure 5 , Figure 5 This is a flowchart illustrating another method for calculating and determining a first threshold provided in an embodiment of this disclosure. Figure 5 As shown, the method may include, but is not limited to, the following steps:

[0203] Step S501: Obtain the reference signal received power (RSRP) threshold.

[0204] As one implementation method, the network device may configure an RSRP threshold and send the RSRP threshold to the eRedCap terminal; alternatively, an RSRP threshold may be agreed upon through a protocol, and this disclosure does not limit this approach.

[0205] Step S502: Determine the first data volume threshold based on the RSRP threshold and the correspondence between RSRP and the data volume threshold.

[0206] After receiving the RSRP threshold sent by the network device, the eRedCap terminal determines the first data volume threshold corresponding to the RSRP threshold based on the correspondence between RSRP and data volume threshold. As one implementation, the correspondence between RSRP and data volume threshold can be configured by the network device and sent to the eRedCap terminal; alternatively, the correspondence between RSRP and data volume threshold can be agreed upon through a protocol. This disclosure does not limit this approach.

[0207] For example, the correspondence between RSRP and data volume threshold is as follows: when RSRP threshold is configured as A1, the first data volume threshold needs to be configured as B1; when RSRP threshold is configured as A2, the first data volume threshold needs to be configured as B2. Therefore, after the eRedCap terminal receives the RSRP threshold sent by the network device, it can configure the first data volume threshold based on the established correspondence between RSRP and data volume threshold.

[0208] In summary, the eRedCap terminal in Method 2 determines an independent first data volume threshold for SDT transmission configuration based on the RSRP threshold and the correspondence between RSRP and data volume threshold, that is, both the RSRP threshold and the first data volume threshold are configured.

[0209] The RSRP threshold and the correspondence between RSRP and data volume threshold can be configured by network devices or agreed upon by protocols; this disclosure does not impose any restrictions.

[0210] Method 3: When the first threshold includes the RSRP threshold, the first threshold is determined by calculation. Please refer to [link to relevant documentation]. Figure 6 , Figure 6 This is a flowchart illustrating another method for calculating and determining a first threshold provided in an embodiment of this disclosure. Figure 6 As shown, the method may include, but is not limited to, the following steps:

[0211] Step S601: Obtain the second adjustment parameter and the second RSRP threshold; wherein the second adjustment parameter includes any one of the following: coefficient, offset.

[0212] The second adjustment parameter and the second RSRP threshold described in this disclosure are both configured by the base station and sent to the eRedCap terminal. For example, the second adjustment parameter is a coefficient (e.g., represented by alpha). The second adjustment parameter alpha can be indicated / configured by the base station, or a specific value can be given by the protocol; this disclosure does not limit this.

[0213] The second adjustment parameter is the offset (e.g., represented by offset). As one possible implementation method of this disclosure, the offset is the offset relative to the non-eRedCap terminal. It can be set according to business requirements, and there is no specific limitation.

[0214] It should be noted that the coefficients and offsets described in this disclosure are both configurable fixed values.

[0215] Step S602: According to the first RSRP threshold calculation rule, the first RSRP threshold is calculated and determined based on the second adjustment coefficient and the second RSRP threshold.

[0216] To ensure the transmission performance of the eRedCap terminal's data channel, an independent first RSRP threshold can be configured for it. The eRedCap terminal obtains the RSRP by measuring the Synchronization Signal and PBCH block (SSB). This RSRP measurement must be less than the first RSRP threshold in order to perform SDT transmission.

[0217] As one possible implementation of this disclosure, to ensure the transmission performance of the eRedCap terminal's data channel, the first RSRP threshold can be higher than the second RSRP threshold. The higher the first RSRP threshold set by the eRedCap terminal, the lower the corresponding link loss. In this case, a higher MCS can be used to transmit a larger TBS, ensuring SDT transmission performance while reducing the transmission latency and terminal power consumption of larger SDT payloads. This disclosure does not limit the size of the first RSRP threshold.

[0218] As one possible implementation of this disclosure, when calculating and determining the first RSRP threshold according to the second adjustment coefficient and the second RSRP threshold according to the first RSRP threshold calculation rule, the following method can be used, but is not limited to: calculating and determining the first RSRP threshold by combining the second RSRP threshold with the second adjustment parameter.

[0219] As one implementation method, it can be a first RSRP threshold calculation rule configured by the network device and sent to the eRedCap terminal; or it can be a first RSRP threshold calculation rule agreed upon by the protocol, which is not limited in this disclosure.

[0220] For eRedCap terminals, the first RSRP threshold can be calculated as follows: alpha2 * RSRP threshold for non-eRedCap terminals, where alpha2 is a second adjustment coefficient, and RSRP threshold for non-eRedCap terminals is the second RSRP threshold. This disclosure does not limit the method for determining the first RSRP threshold.

[0221] In summary, Method 3 configures an independent first RSRP threshold for eRedCap terminal SDT transmission.

[0222] This disclosure provides a method for obtaining a second adjustment parameter. This method can be executed alone, or in combination with any embodiment of this disclosure or possible implementations within an embodiment, or in combination with any technical solution in the related art. One possible implementation of this disclosure is obtaining the second adjustment parameter. Another possible implementation involves receiving the second adjustment parameter sent by a network device via transmission signaling. The principle of obtaining the second adjustment parameter is similar to that of the first adjustment parameter method; for further details, please refer to the detailed description of obtaining the first adjustment parameter method, and therefore will not be repeated here.

[0223] Method 4: When the first threshold includes the RSRP threshold, the first threshold is determined by calculation. Please refer to [link to relevant documentation]. Figure 7 , Figure 7 This is a flowchart illustrating another method for calculating and determining a first threshold provided in an embodiment of this disclosure. Figure 7 As shown, the method may include, but is not limited to, the following steps:

[0224] Step S701: Obtain the data volume threshold.

[0225] As one implementation method, the network device may configure a data volume threshold and send the data volume threshold to the eRedCap terminal; alternatively, a data volume threshold may be agreed upon through a protocol, and this disclosure does not limit this method.

[0226] Step S702: Determine the first RSRP threshold based on the data volume threshold and the correspondence between RSRP and the data volume threshold.

[0227] After receiving the data volume threshold sent by the network device, the eRedCap terminal determines the first RSRP threshold corresponding to the data volume threshold based on the correspondence between RSRP and the data volume threshold. The correspondence between RSRP and the data volume threshold can be configured by the network device or agreed upon by the protocol, and this disclosure does not limit it.

[0228] For example, the correspondence between RSRP and data volume threshold is as follows: when the data volume threshold needs to be configured as B1, the first RSRP threshold is configured as A1; when the data volume threshold needs to be configured as B2, the first RSRP threshold is configured as A2. Therefore, after the eRedCap terminal receives the data volume threshold sent by the network device, the first RSRP threshold can be configured based on the established correspondence between RSRP and data volume threshold.

[0229] In summary, eRedCap terminal in Method 4 determines an independent first RSRP threshold for SDT transmission configuration based on the data volume threshold configured by the network device and the correspondence between RSRP and the data volume threshold. That is, both the first RSRP threshold and the data volume threshold are configured.

[0230] Methods one through four described above illustrate how the eRedCap terminal determines the first threshold through calculation.

[0231] Method 5: Receive the first threshold sent by the network device through transmission signaling.

[0232] In practical applications, when the eRedCap terminal receives the first threshold sent by the network device via transmission signaling, it determines the received first threshold as the eRedCap terminal's first threshold. That is, after the network device configures the first threshold, it sends it to the eRedCap terminal, which receives the first threshold configured by the network device and uses it as its first threshold.

[0233] Specifically, when determining the first threshold in the eRedCap terminal, this disclosure can use any of the methods provided in Method 1 to Method 5 above, and this disclosure does not limit it.

[0234] The transmission signaling described in this disclosure is any of the following: Radio Resource Control (RRC) Release message and System information block 1 (SIB1). This disclosure does not specifically limit the transmission signaling.

[0235] This disclosure provides another Small Data Packet Transmission (SDT) method. Figure 8This is a flowchart illustrating another Small Data Packet Transmission (SDT) method provided in an embodiment of this disclosure, as shown below. Figure 8 As shown, the Small Data Packet Transmission (SDT) method may include the following steps:

[0236] Step S201: In response to the eRedCap terminal supporting SDT transmission, determine a first threshold, and determine whether to perform SDT transmission based on the first threshold. The first threshold may be the same as or different from a second threshold. The second threshold is a threshold applied to non-eRedCap terminals without enhancement reduction capability.

[0237] When determining the first threshold, the following can be used, but are not limited to:

[0238] Step S2011: In response to the second data volume threshold being less than or equal to the maximum TBS processing capacity of the eRedCap terminal, the second threshold is determined as the first threshold.

[0239] In this scenario, if the second data volume threshold is determined to be less than or equal to the maximum TBS processing capacity of the eRedCap terminal, the eRedCap terminal can directly set the second threshold configured by the network device as the first threshold, and the first threshold is the same as the second threshold. SDT transmission can then be performed using the second threshold.

[0240] For a description of step S201, please refer to the detailed description of any of the above embodiments, and therefore it will not be repeated here.

[0241] In summary, after determining that it supports SDT transmission, the eRedCap terminal, in response to the second data volume threshold being less than or equal to the eRedCap terminal's maximum TBS processing capacity, determines the second threshold as the first threshold, and determines whether to perform SDT transmission based on the first threshold. By introducing an independent SDT transmission threshold for the eRedCap terminal, reasonable scheduling of the eRedCap terminal can be ensured.

[0242] This disclosure provides another Small Data Packet Transmission (SDT) method. Figure 9 This is a flowchart illustrating another Small Data Packet Transmission (SDT) method provided in an embodiment of this disclosure, as shown below. Figure 9 As shown, the Small Data Packet Transmission (SDT) method may include the following steps:

[0243] Step S201: In response to the eRedCap terminal supporting SDT transmission, a first threshold is determined, and whether to perform SDT transmission is determined based on the first threshold. The first threshold includes a first data volume threshold.

[0244] Step S203: In response to the first data volume threshold being greater than the maximum TBS processing capacity of the eRedCap terminal, it is determined that SDT transmission will not be performed, the RACH procedure is triggered, and the connection state is entered.

[0245] If the first data volume threshold is determined to be greater than the maximum processing capacity of the eRedCap terminal's TBS, the goal of reducing power consumption through SDT transmission in the inactive state cannot be achieved. In order to ensure that the base station triggers the RACH procedure and enters the connected state when performing Msg3 scheduling, the base station will be able to achieve this.

[0246] For details on how to trigger the RACH procedure and enter the connected state, please refer to any relevant technical descriptions; this disclosure will not elaborate further.

[0247] It should be noted that the embodiments of this disclosure may include multiple steps (steps S201 and S203). For ease of description, these steps are numbered, but these numbers are not limitations on the execution time slots or execution order between the steps. Rather, they are executed separately under different conditions or in different scenarios.

[0248] For a description of step S201, please refer to the detailed description of any of the above embodiments, and therefore it will not be repeated here.

[0249] In summary, after determining that it supports SDT transmission, the eRedCap terminal determines a first threshold and decides whether to perform SDT transmission based on the first threshold. In response to the first data volume threshold being greater than the maximum TBS processing capacity of the eRedCap terminal, it determines not to perform SDT transmission, triggers the RACH procedure, and enters the connected state. By introducing an independent SDT transmission threshold for the eRedCap terminal, reasonable scheduling of the eRedCap terminal can be ensured.

[0250] It should be noted that the embodiments of this disclosure may include multiple steps. For ease of description, these steps are numbered, but these numbers are not a limitation on the execution time slots or execution order between the steps; these steps can be implemented in any order, and the embodiments of this disclosure do not limit this.

[0251] This disclosure provides another Small Data Packet Transmission (SDT) method. Figure 10 This is a flowchart illustrating another Small Data Packet Transmission (SDT) method provided in an embodiment of this disclosure, as shown below. Figure 10 As shown, this method is executed by a network device, and the Small Data Packet Transmission (SDT) method may include the following steps:

[0252] Step S1001: In response to the eRedCap terminal supporting SDT transmission, configure a first threshold for the eRedCap terminal.

[0253] Step S1002: Send the first threshold to the eRedCap terminal.

[0254] In practical applications, the transmission signaling is any one of the following signaling types: RRC Release, SIB1. This disclosure does not limit the signaling type of the transmission signaling.

[0255] In summary, in response to the eRedCap terminal supporting SDT transmission, the network device configures a first threshold for the eRedCap terminal and sends the first threshold to the eRedCap terminal. After receiving the first threshold sent by the network device, the eRedCap terminal determines the first threshold and determines whether to perform SDT transmission based on the first threshold. In response to the first data volume threshold being greater than the maximum processing capacity of the eRedCap terminal's TBS, it determines not to perform SDT transmission, triggers the RACH procedure, and enters the connected state. By introducing an independent SDT transmission threshold for the eRedCap terminal, reasonable scheduling of the eRedCap terminal can be ensured.

[0256] The first threshold and the second threshold may be the same as or different, where the second threshold is a threshold applied to non-eRedCap terminals without enhanced reduction capabilities. The first threshold includes at least one of the following: a first data volume threshold and a first reference signal received power (RSRP) threshold; the second threshold includes at least one of the following: a second data volume threshold and a second RSRP threshold; wherein the first data volume threshold and the second data volume threshold are the same as or different, and the first RSRP threshold and the second RSRP threshold are the same as or different. For details regarding whether the first threshold on the network device side and the first threshold on the eRedCap terminal side are the same, please refer to the detailed description of any of the above embodiments, and therefore will not be repeated here.

[0257] This disclosure provides another Small Data Packet Transmission (SDT) method. Figure 11 This is a flowchart illustrating a method for configuring a first threshold for an eRedCap terminal according to an embodiment of this disclosure, as shown below. Figure 11 As shown, this method is executed by a network device, and the Small Data Packet Transmission (SDT) method may include the following steps:

[0258] Step S1101: Receive terminal capability information sent by each eRedCap terminal.

[0259] After establishing communication with the network device or during PRACH transmission, the eRedCap terminal reports its terminal capability information to the network device. This terminal capability information includes, but is not limited to, terminal capability information such as bandwidth and antenna.

[0260] Step S1102: Determine whether each eRedCap terminal supports SDT transmission based on the terminal capability information.

[0261] Step S1103: If SDT transmission is supported, configure a first threshold for the eRedCap terminal.

[0262] After determining that the eRedCap terminal supports SDT transmission, an independent first threshold is configured to support SDT transmission to ensure that the eRedCap terminal is scheduled appropriately.

[0263] When configuring the first threshold for the eRedCap terminal, the network device may use, but is not limited to, the following three methods:

[0264] Method 1: Configure a first threshold for the eRedCap terminal, the first threshold being different from the second threshold.

[0265] In Method 1, the network device configures a first threshold for eRedCap terminals and a second threshold for non-eRedCap terminals. In this configuration method, the first and second thresholds are different.

[0266] Method 2: In response to the second data volume threshold being greater than the maximum TBS processing capacity of the eRedCap terminal, a first threshold is configured for the eRedCap terminal, the first threshold being different from the second threshold.

[0267] When the second data volume threshold exceeds the maximum TBS processing capacity of the eRedCap terminal, in order to ensure reasonable scheduling of the eRedCap terminal and avoid affecting the SDT transmission of non-eRedCap terminals, the network device configures a first threshold for the eRedCap terminal. The first threshold is different from the second threshold.

[0268] Method 3: In response to the second data volume threshold being less than or equal to the maximum TBS processing capacity of the eRedCap terminal, the second threshold is determined as the first threshold, and the first threshold is configured for the eRedCap terminal, wherein the first threshold is the same as the second threshold.

[0269] In this scenario, if the second data volume threshold is determined to be less than or equal to the maximum TBS processing capacity of the eRedCap terminal, the e-network device can directly determine the configured second threshold as the first threshold, at which point the first threshold and the second threshold are the same.

[0270] This disclosure provides another Small Data Packet Transmission (SDT) method. Figure 12This is a flowchart illustrating another Small Data Packet Transmission (SDT) method provided in an embodiment of this disclosure, as shown below. Figure 12 As shown, this method is executed by a network device, and the Small Data Packet Transmission (SDT) method may include the following steps:

[0271] Step S1003: Send the first adjustment parameter, the second adjustment parameter, and the second threshold to the eRedCap terminal via transmission signaling.

[0272] The first adjustment parameter, the second adjustment parameter, and the second threshold are respectively sent to the eRedCap terminal so that the eRedCap terminal can determine its first threshold based on the first adjustment parameter, the second adjustment parameter, the second threshold, and the calculation rules. For a description of how the eRedCap terminal determines the first threshold through calculation, please refer to the detailed description of any of the above embodiments, and therefore will not be repeated here.

[0273] The transmission signaling is any one of the following: RRC Release, SIB1. This disclosure does not limit the signaling type of the transmission signaling.

[0274] It should be noted that when the network device sends the first threshold to the eRedCap terminal via RRRCRelease, configuring the first threshold for the eRedCap terminal includes configuring different first thresholds for different eRedCap terminals.

[0275] When the first threshold is sent to the eRedCap terminal via SIB1, configuring the first threshold for the eRedCap terminal includes: configuring the same first threshold for different eRedCap terminals, and configuring the same second threshold for different non-eRedCap terminals. That is, SIB1 carries the same threshold for a class of devices.

[0276] With the above Figures 2 to 9 Corresponding to the Small Data Packet Transmission (SDT) method provided in the embodiments, this disclosure also provides a Small Data Packet Transmission (SDT) device. Since the Small Data Packet Transmission (SDT) device provided in this disclosure is similar to the one described above... Figures 2 to 9 The Small Data Packet Transmission (SDT) method provided in the embodiments corresponds to the Small Data Packet Transmission (SDT) method, and therefore the implementation of the Small Data Packet Transmission (SDT) method is also applicable to the Small Data Packet Transmission (SDT) device provided in the embodiments of this disclosure, and will not be described in detail in the embodiments of this disclosure.

[0277] Figure 13 This is a schematic diagram of a Small Data Packet Transmission (SDT) transmission device provided in an embodiment of the present disclosure. The device is installed in an enhanced redcap (eRedCap) terminal and includes:

[0278] Processing module 131 is configured to, in response to the eRedCap terminal supporting SDT transmission, determine a first threshold and determine whether to perform SDT transmission based on the first threshold;

[0279] The processing module 131 is also used to trigger a random access RACH procedure and enter the connected state in response to the fact that the eRedCap terminal does not support SDT transmission.

[0280] As one possible implementation of this disclosure, the first threshold and the second threshold may be the same or different, and the second threshold is a threshold applied to non-eRedCap terminals with non-enhanced capability reduction.

[0281] The first threshold includes at least one of the following: a first data volume threshold and a first reference signal received power (RSRP) threshold;

[0282] The second threshold includes at least one of the following: a second data volume threshold, and a second RSRP threshold;

[0283] Wherein, the first data volume threshold is the same as or different from the second data volume threshold, and the first RSRP threshold is the same as or different from the second RSRP threshold.

[0284] As one possible implementation of this disclosure, the processing module 131 is further configured to:

[0285] The first threshold is determined by calculation.

[0286] As one possible implementation of this disclosure, when the first threshold includes a first data volume threshold, the processing module 131 is further configured to:

[0287] Obtain a first adjustment parameter and a second data volume threshold; wherein the first adjustment parameter includes any one of the following: a coefficient or an offset;

[0288] The first data volume threshold is determined by calculation based on the first adjustment parameter, the second data volume threshold, and the maximum TBS processing capacity of the eRedCap terminal.

[0289] As one possible implementation of this disclosure, the processing module 131 is further configured to obtain the first adjustment parameter;
