Detailed ways

In order to have a more detailed understanding of the characteristics and technical content of the embodiments of the present application, the implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings. The attached drawings are for reference and explanation purposes only, and are not used to limit the embodiments of the present application.

At present, with people's pursuit of speed, delay, high-speed mobility, energy efficiency, and the diversity and complexity of services in future life, the 3GPP International Standards Organization has begun to develop 5G. The main application scenarios of 5G are: Enhance Mobile Broadband (eMBB), Ultra Reliable Low Latency Communications (URLLC), and Massive Machine Type Communication (mMTC).

eMBB still aims for users to obtain multimedia content, services and data, and its demand is growing very rapidly. Since eMBB may be deployed in different scenarios, such as indoors, urban areas, rural areas, etc., the capabilities and requirements of eMBB vary greatly in different scenarios. Therefore, it cannot be generalized and must be analyzed in detail in conjunction with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, telemedicine operations (surgery) and traffic safety assurance. Typical features of mMTC include: high connection density, small data volume, delay-insensitive services, low-cost modules and long service life.

In the early deployment of New Radio (NR), it is difficult to obtain complete NR coverage; therefore, the typical network coverage is wide-area LTE coverage and NR island coverage mode. In addition, because a large number of LTE systems are deployed in the frequency spectrum below 6GHz, there is very little spectrum below 6GHz that can be used for NR systems; therefore, NR systems must study spectrum applications above 6GHz. However, high-frequency spectrum has limited coverage and signal Disadvantages of fast fading. At the same time, in order to protect the mobile operators' early investment in the LTE system, a tight interworking working mode between the LTE system and the NR system has been proposed. The NR system can also work independently. In the NR system, the maximum channel bandwidth can be 400MHZ (wideband carrier). Compared with the maximum 20M bandwidth of the LTE system, the bandwidth of the NR system is very large.

In the LTE system, Early Data Transmission (EDT), that is, small data transmission, has been introduced. A schematic diagram of the processing flow of small data transmission, as shown in Figure 1, the terminal device may always remain in an idle state, a suspend state, or an inactive state. In step a to step h, the terminal device and the network The connection between the devices is not established, but in step e and step f, the transmission of the uplink and/or downlink small data packets is completed between the network device and the serving gateway. In the small data transmission process, the terminal device completes the transmission of small data without entering the connected state; the transmission of small data is different from the terminal device entering the connected state to transmit MBB services.

For small data transmission, the network device will configure a maximum transport block (TB) size (size) that the current network device allows to transmit on SIB2. The terminal device determines that the amount of data to be transmitted is less than the maximum TB size, then the terminal device EDT can be initiated; otherwise, the terminal device triggers the connection establishment process and enters the connected state to transmit data.

The following briefly describes the first type of random access and the second type of random access.

In the NR system, RACH includes: the first type of random access and the second type of random access. Among them, in the first type of random access, two information exchanges are required between the terminal device and the network device. Therefore, the first type of random access is also called two-step random access (2-steps RACH). In the second type of random access, the terminal device and the network device need to perform 4 information exchanges; therefore, the second type of random access is also called 4-steps RACH. According to different random access methods, random access includes contention-based random access and non-contention-based random access. According to the different types of random access, random access includes the first type of random access and the second type of random access. The following briefly describes the first type of random access and the second type of random access.

The processing flow of the second type of random access, as shown in Figure 2, includes the following four steps:

Step S101: The terminal device sends a random access preamble (Preamble) to the network device through Msg1.

The terminal device sends the selected Preamble on the selected PRACH time domain resource; the network device can estimate the uplink Timing and the size of the uplink authorization required for the terminal device to transmit Msg3 based on the Preamble.

Step S102: After detecting that a terminal device sends a Preamble, the network device sends a random access response (Random Access Response, RAR) message to the terminal device through Msg2 to inform the terminal device of the uplink resource information that can be used when sending Msg3. The equipment allocates a temporary radio network temporary identity (RNTI) to provide time advance command for terminal equipment.

Step S103: After receiving the RAR message, the terminal device sends Msg3 in the uplink resource specified by the RAR message.

Among them, the message of Msg3 is mainly used to notify the network device of what event triggered the RACH process. For example, if it is an initial random access event, the terminal device ID and establishment cause will be carried in Msg3; if it is an RRC reestablishment event, the connected terminal device identification and establishment cause will be carried in Msg3.

At the same time, the contention conflict that the ID carried by Msg3 may be is resolved in step S104.

Step S104: The network device sends Msg4 to the terminal device, and Msg4 includes a contention resolution message, and at the same time allocates uplink transmission resources for the terminal device.

When the terminal device receives the Msg4 sent by the network device, it will detect whether the terminal device specific temporary identifier sent by the terminal device in Msg3 is included in the contention resolution message sent by the base station. If it is included, it indicates that the random access process of the terminal device is successful, otherwise it is considered random If the process fails, the terminal device needs to initiate the random access process again from the first step.

Another function of Msg4 is to send a radio resource control (Radio Resource Control, RRC) configuration message to the terminal device.

The above-mentioned RACH process requires four times of information exchange between the network equipment and the terminal equipment, resulting in the time extension of the RACH process; in order to solve the problem of the time extension of the RACH process, the first type of random access and the first type of random access processing are proposed. The process, as shown in Figure 3, includes the following steps:

Step S201: The terminal device sends MsgA to the network device.

MsgA is composed of Preamble and payload. Optionally, the preamble is the same as the preamble in the second type of random access, and the preamble is transmitted on the PRACH resource; the information carried in the payload is the same as the information in the Msg3 in the second type of random access, for example, when the RRC is in an idle state For RRC signaling and C-RNTI when RRC is in the connected state, the payload can be transmitted by the Physical Uplink Shared Channel (PUSCH).

The results of the network device receiving MsgA may include the following two types: the first type, the network device successfully decodes one or more preambles; the second type, the network device successfully decodes one or more preambles and one or more payloads.

Step S202: The terminal device receives the MsgB sent by the network device.

Optionally, MsgB includes the content of Msg2 and Msg4 in the second type of random access.

In the first type of random access process, PUSCH resources are pre-configured through broadcast messages, and PUSCH resources are used to carry RRC messages to be sent by terminal equipment; because the RRC messages at the initial establishment are of a fixed size, the PUSCH resources are The size is also fixed.

However, after the introduction of small data transmission, the PUSCH of the first type of random access needs to carry small data, so that the size of the pre-configured PUSCH resource also needs to be increased accordingly. However, since the network device is not sure when the terminal device initiates small data transmission, blindly increasing the size of the PUSCH resource will cause a waste of network resources. Therefore, how to perform reasonable and effective small data transmission in the first type of random access has not yet been clarified.

Based on the above problems, this application provides a data transmission method. The technical solutions of the embodiments of this application can be applied to various communication systems, such as the global system of mobile communication (GSM) system, code division multiple access (code division multiple access, GSM) system, etc. division multiple access (CDMA) system, wideband code division multiple access (WCDMA) system, general packet radio service (GPRS), long term evolution (LTE) system, LTE frequency Frequency division duplex (FDD) system, LTE time division duplex (TDD) system, advanced long term evolution (LTE-A) system, new radio (NR) system , The evolution of the NR system, the LTE (LTE-based access to unlicensed spectrum, LTE-U) system on the unlicensed frequency band, the NR (NR-based access to unlicensed spectrum, NR-U) system on the unlicensed frequency band, and the general Mobile communication system (universal mobile telecommunication system, UMTS), worldwide interoperability for microwave access (WiMAX) communication system, wireless local area networks (WLAN), wireless fidelity (wireless fidelity, WiFi), Next-generation communication systems or other communication systems, etc.

An optional processing procedure of the data transmission method provided in the embodiment of the present application, as shown in FIG. 5, includes the following steps:

Step S301: The terminal device transmits small data or transmits small data indication information based on the maximum transmission block size of the PUSCH in the first type of random access.

In some embodiments, in the first type of random access (2-step RACH), the network device can configure the terminal device with 2-step RACH resources through system broadcast messages, such as random access opportunity (RACH Occasion, RO) and PUSCH resource. Wherein, the PUSCH resource indicates the maximum transport block (Transport Block, TB) size (size) that can be transmitted by the PUSCH.

In some embodiments, the small data that the terminal device needs to transmit may be data in the EDT. Before transmitting the small data, the terminal device may compare the size of the small data to be transmitted with the size of the TB size of the PUSCH; transmit the small data or transmit the small data indication information according to the size relationship between the two.

The following describes the data transmission method in the embodiment of the present application based on the different relationship between the size of the small data to be transmitted and the size of the TB size of the PUSCH.

Example one

When the size of the small data to be transmitted by the terminal device is less than or equal to the maximum transmission block size, the terminal device transmits the small data.

In some embodiments, the terminal device may only transmit the small data in the PUSCH. In this scenario, the size of the data transmitted on the PUSCH is the size of the small data; that is, the resource in the 2-step RACH is a resource dedicated to the terminal device, and the resource may be configured by the network device to the terminal device when the connection is released.

In other embodiments, the terminal device may transmit the small data and the radio resource control message through the PUSCH; that is, the small data and the radio resource control message are multiplexed on the PUSCH for transmission. In this scenario, the size of the data transmitted on the PUSCH is the sum of the size of the small data and the size of the radio resource control message. Wherein, the radio resource control message may be a radio resource control resume request (RRC Resume Request) message.

Example two

In the case that the size of the small data to be transmitted by the terminal device is greater than the maximum transmission block size, the terminal device needs to further determine whether the small data to be transmitted is different from the indication information for transmitting the small data based on the first type of random access. The size of the maximum amount of data that can be transmitted at a time, and determining whether the maximum transmission block size can accommodate the size of the small data indication information. When the size of the small data to be transmitted by the terminal device is greater than the maximum transmission block size, the size of the small data is not greater than the maximum amount of data that can be transmitted when the small data indication information is transmitted based on the first type of random access, And when the maximum transmission block size can accommodate the size of the small data indication information, the terminal device transmits the small data indication information.

For example, the size of the small data to be transmitted is 1500 kb, the maximum transmission block size of PUSCH is 1000 kb, and the size of the maximum amount of data that can be transmitted when the small data indication information is transmitted based on the first type of random access is 2000 kb ; That is, the size of the small data to be transmitted by the terminal device is greater than the maximum transmission block size, and the size of the small data is not greater than the maximum data that can be transmitted when the small data indication information is transmitted based on the first type of random access If the maximum transmission block size of the PUSCH can accommodate the size of the small data indication information, the terminal device transmits the small data indication information.

In some embodiments, the terminal device only transmits the small data indication information through the PUSCH; in this scenario, the size of the data transmitted on the PUSCH is the size of the small data indication information. That is, the resources in the 2-step RACH are resources dedicated to the terminal equipment, and the resources may be configured by the network equipment to the terminal equipment when the connection is released.

In other embodiments, the terminal device may transmit the small data indication information and the radio resource control message through the PUSCH; that is, the small data indication information and the radio resource control message are multiplexed on the PUSCH for transmission. In this scenario, the size of the data transmitted on the PUSCH is the sum of the size of the small data indication information and the size of the radio resource control message. Wherein, the radio resource control message may be a radio resource control resume request (RRC Resume Request) message.

In still other embodiments, the terminal device transmits the small data indication information and part of the small data through the PUSCH; that is, the small data indication information and part of the data to be transmitted are multiplexed on the PUSCH for transmission. In this scenario, the small data indication information may further indicate the size of the remaining data to be transmitted; so that after receiving the PUSCH, the network device can schedule the data through MsgB/RAR according to the small data size information indicated in the small data indication information. The terminal equipment transmits small data on the PUSCH. Therefore, the terminal device may receive scheduling information sent by the network device, where the scheduling information is used to schedule the terminal device to transmit the remaining data to be transmitted.

In the embodiment of the present application, the small data indication information may include: first indication information used to indicate small data, and/or second indication information used to indicate the size of the small data. Wherein, the first indication information indicates that the data to be transmitted by the terminal device is small data, and the first indication information may be only 1 bit. The second indication information may be carried in the first MAC CE, or carried in the buffer status report (Buffer Status Report, BSR) MAC CE. Wherein, the first MAC CE is a new MAC CE that is different from the existing MAC CE; for example, the first MAC CE has a different form from the existing MAC CE, or carries different information content.

In some embodiments, the data transmission method may further include:

Step S300: The terminal device receives third indication information, where the third indication information is used to indicate whether the terminal device is allowed to use the PUSCH to transmit the small data.

In a specific implementation, the third indication information may be sent by a network device. Only when the indication information is used to indicate that the terminal device is allowed to use the PUSCH to transmit the small data, the terminal device may be based on In the first type of random access, the maximum transmission block size of the PUSCH transmits the small data.

In some embodiments, the data transmission method may further include:

In step S300', the terminal device receives fourth indication information, where the fourth indication information is used to indicate the maximum amount of data that can be transmitted when the small data indication information is transmitted based on the first type of random access.

The foregoing is directed to scenarios where the size of small data is less than or equal to the maximum transmission block size, and the size of the small data is greater than the maximum transmission block size, and the size of the small data is not greater than that based on the first type of random access The scenario of the maximum amount of data that can be transmitted when transmitting the small data indication information describes the data transmission method provided in the embodiment of the present application.

Then, when the network device does not allow the terminal device to use the PUSCH to transmit the small data, or the size of the small data to be transmitted by the terminal device is larger than the small data indication information that can be transmitted based on the first type of random access In the case of the maximum amount of data, the terminal device uses the first type of random access to establish a radio resource control connection; when the terminal device enters the connected state, the small data is transmitted.

Another optional processing procedure of the data transmission method provided by the embodiment of the present application, as shown in FIG. 6, includes the following steps:

Step S401: The network device receives small data or small data indication information through the PUSCH in the first type of random access.

In some embodiments, the network device receives the small data when the size of the small data is less than or equal to the maximum transport block size of the PUSCH in the first type of random access. In a specific implementation, the network device may only receive the small data through the PUSCH; or, the network device may receive and transmit the small data and the radio resource control message through the PUSCH.

In other embodiments, when the size of the small data is greater than the maximum transmission block size, and the size of the small data is not greater than that which can be transmitted when the small data indication information is transmitted based on the first type of random access In the case of the maximum data amount and the maximum transmission block size can accommodate the size of the small data indication information, the network device receives the small data indication information.

Wherein, the small data indication information may include: first indication information used to indicate small data, and/or second indication information used to indicate a size of the small data. Wherein, the first indication information indicates that the data to be transmitted by the terminal device is small data, and the first indication information may be only 1 bit. The second indication information may be carried in the first MAC CE, or carried in the BSR MAC CE. Wherein, the first MAC CE is a new MAC CE that is different from the existing MAC CE; for example, the first MAC CE has a different form from the existing MAC CE, or carries different information content.

In some embodiments, the network device receiving small data indication information includes: the network device receives only the small data indication information through the PUSCH; or, the network device receives the small data indication through the PUSCH Information and radio resource control messages; or, the network device receives the small data indication information and part of the small data through the PUSCH.

In the case that the network device receives the small data indication information and part of the small data through the PUSCH, the small indication information is also used to indicate the size of the remaining data to be transmitted in the small data . In this scenario, the method may further include:

Step S402: The network device sends scheduling information, where the scheduling information is used to schedule the terminal device to transmit the remaining data to be transmitted.

In the data transmission method provided in the embodiment of the present application, the method may further include:

Step S400: The network device sends third indication information, where the third indication information is used to indicate whether the terminal device is allowed to use the PUSCH to transmit the small data.

Step S400', the network device sends fourth indication information, where the fourth indication information is used to indicate the maximum amount of data that can be transmitted when the small data indication information is transmitted based on the first type of random access.
