Detailed Description

So that the manner in which the features and technical contents of the embodiments of the present application can be understood in detail, a detailed description of the embodiments of the present application will be given below with reference to the accompanying drawings, which are provided for illustration purposes and are not intended to limit the embodiments of the present application.

Currently, with the pursuit of speed, delay, high-speed mobility, energy efficiency, and 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: enhanced Mobile Ultra wide band (eMBB), Low Latency high reliability Communications (URLLC), and Massive Machine Type Communications (mMTC).

The eMBB still targets users to obtain multimedia content, services and data, and its demand is growing very rapidly. Because the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., the difference between the capabilities and the requirements of the eMBB is relatively large in different scenarios, so it cannot be summarized, and it must be analyzed in detail in combination with a specific deployment scenario. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety, and the like. Typical characteristics of mtc include: high connection density, small data volume, insensitive time delay service, low cost and long service life of the module, etc.

In early deployments of New Radio (NR), it is difficult to obtain complete NR coverage; typical network coverage is wide area LTE coverage and islanding coverage mode of NR. Also, since a large number of LTE systems are deployed in the spectrum below 6GHz, the spectrum below 6GHz available for NR systems is rare; therefore, NR systems must study spectrum applications above 6GHz, however, the spectrum in the high band has the disadvantages of limited coverage and fast signal fading. Meanwhile, in order to protect the early investment of the mobile operator on the LTE system, a work mode of tight interworking (light interworking) between the LTE system and the NR system is proposed. The NR system may also operate independently, and in the NR system, the maximum channel bandwidth may be 400mhz (wideband carrier), which is large compared to the maximum 20M bandwidth of the LTE system.

In the LTE system, Early Data Transmission (EDT), i.e., small Data Transmission, has been introduced. As shown in fig. 1, the terminal device may be always maintained in an idle (idle) state, a standby (suspend) state, or an active (inactive) state, in steps a to h, a connection between the terminal device and the network device is not established, but in steps e and f, transmission of 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 equipment completes the transmission of the small data under the condition that the terminal equipment does not enter a connection state; the transmission of the small data is different from the transmission of MBB service when the terminal equipment enters a connection state.

For small data transmission, the network device configures a size (size) of a maximum Transport Block (TB) that the current network device allows to transmit on SIB2, and the terminal device determines that the amount of data to be transmitted is smaller than the maximum TB size, and then the terminal device may initiate EDT; otherwise, the terminal equipment triggers a connection establishment process and enters a connection state to transmit data.

The first and second types of random access will be briefly described below.

In the NR system, the RACH includes: a first type of random access and a second type of random access. In the first type of random access, 2 times of information interaction needs to be performed between the terminal device and the network device, and therefore, the first type of random access is also called two-step random access (2-steps RACH). In the second type of random access, 4 times of information interaction is required to be executed between the terminal equipment and the network equipment; therefore, the second type of random access is also referred to as four-step random access (4-steps RACH). The random access includes contention-based random access and non-contention-based random access according to different random access modes. The random access includes a first type random access and a second type random access according to different types of random access. The first and second types of random access will be briefly described below.

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

step S101, the terminal device sends a random access Preamble (Preamble) to the network device through the Msg 1.

The terminal equipment sends the selected Preamble on the selected PRACH time domain resource; and the network equipment can estimate the uplink Timing and the size of the uplink authorization required by the terminal equipment for transmitting the Msg3 according to the Preamble.

Step S102, after detecting that the terminal device sends a Preamble, the Network device sends a Random Access Response (RAR) message to the terminal device through the Msg2, so as to inform the terminal device of uplink resource information that can be used when sending the Msg3, allocate a temporary Radio Network Temporary Identity (RNTI) to the terminal device, and provide a time advance command for the terminal device.

In step S103, after receiving the RAR message, the terminal device sends Msg3 in the uplink resource specified by the RAR message.

The Msg3 message is mainly used to inform the network device what event triggered the RACH procedure. For example, if it is an initial random access event, the Msg3 carries the terminal device ID and the estipalishment cause; if the event is an RRC reestablishment event, the Msg3 carries the connected terminal device identifier and the estipalishment cause.

Meanwhile, contention conflicts that the ID carried by Msg3 may be are resolved in step S104.

And step S104, the network equipment sends Msg4 to the terminal equipment, the Msg4 comprises a competition resolving message, and uplink transmission resources are distributed for the terminal equipment.

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 Msg3 by the terminal device 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 that the random access process is failed, and the terminal device needs to initiate the random access process from the first step again.

Another role of the Msg4 is to send a Radio Resource Control (RRC) configuration message to the terminal device.

The RACH procedure is completed by performing four times of information interaction between the network device and the terminal device, resulting in a long delay time of the RACH procedure; to solve the problem of the lengthening of the RACH procedure, a first type of random access is proposed, and a processing procedure of the first type of random access is provided, as shown in fig. 3, including the following steps:

step S201, the terminal device sends MsgA to the network device.

MsgA consists 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 payload carries the same information as Msg3 in the second type of random access, such as RRC signaling when RRC is in idle state and C-RNTI when RRC is in connected state, and can be transmitted by Physical Uplink Shared Channel (PUSCH).

The results of the network device receiving the MsgA may include the following two: firstly, the network equipment successfully decodes one or more preambles; second, the network device successfully decodes one or more preambles and one or more payload.

Step S202, the terminal equipment receives the MsgB sent by the network equipment.

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

In the first type of random access process, the PUSCH resource is preconfigured through a broadcast message, and the PUSCH resource is used for bearing an RRC message to be sent by the terminal equipment; since the RRC message at the initial setup is fixed in size, the size of the PUSCH resource is also fixed.

However, after small data transmission is introduced, the size of the preconfigured PUSCH resource also needs to be increased due to the fact that the PUSCH of the first type random access needs to carry small data. However, since the network device does not determine when the terminal device initiates small data transmission, the blind increase of 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 random access is not yet clear.

Based on the above problems, the present application provides a data transmission method, and the technical solution of the embodiments of the present application can be applied to various communication systems, for example: a global system for mobile communications (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a long term evolution (long term evolution, LTE) system, a LTE frequency division duplex (frequency division duplex, FDD) system, a LTE time division duplex (time division duplex, TDD) system, an advanced long term evolution (advanced long term evolution, LTE-a) system, a new radio (new NR) system, an LTE system of an NR system, an LTE (long term evolution-unlicensed-universal-radio, LTE-unlicensed-universal-radio, an NR system of an unlicensed band, an LTE (non-licensed-universal-radio, NR) system of an unlicensed band, an NR system of a mobile-radio (unlicensed-universal-radio, LTE-unlicensed-universal-radio, NR) system of an unlicensed band, an NR system of a mobile-radio (unlicensed band, an NR) system of an unlicensed band, an NR system of a mobile-unlicensed band, an NR system of an unlicensed band, an unlicensed band-universal-radio, an NR system of a radio-unlicensed band, an NR system of a mobile-radio system, UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, Wireless Local Area Network (WLAN), wireless fidelity (WiFi), next generation communication system, or other communication system.

As shown in fig. 5, an optional processing flow of the data transmission method provided in the embodiment of the present application includes the following steps:

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

In some embodiments, in the first type of random access (2-step RACH), the network device may configure the terminal device with resources of the 2-step RACH, such as random access opportunity (RACH occupancy, RO) and PUSCH resources, through a system broadcast message. Wherein the PUSCH resource indicates a maximum Transport Block (TB) size (size) that the PUSCH can Transport.

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 equipment may compare the size of the small data to be transmitted with the size of the TB size of the PUSCH; and transmitting the small data or transmitting the small data indication information according to the size relation of the small data and the small data.

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

Example one

And under the condition that the size of the small data to be transmitted by the terminal equipment is smaller than or equal to the size of the maximum transmission block, the terminal equipment transmits the small data.

In some embodiments, the terminal device may transmit only 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 to the terminal device by the network device when the connection is released.

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

Example two

When the size of the small data to be transmitted by the terminal device is larger than the size of the maximum transmission block, the terminal device needs to further determine the size of the small data to be transmitted and the maximum data amount that can be transmitted when the small data indication information is transmitted based on the first type random access, and determine whether the size of the maximum transmission block can accommodate the size of the small data indication information. And under the conditions that the size of small data to be transmitted by the terminal equipment is larger than the size of the maximum transmission block, the size of the small data is not larger than the maximum data quantity which can be transmitted when the small data indication information is transmitted based on the first type random access, and the size of the maximum transmission block can accommodate the size of the small data indication information, the terminal equipment transmits the small data indication information.

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

In some embodiments, the terminal device transmits only the small data indication information over 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 resource in the 2-step RACH is a resource dedicated to the terminal device, and the resource may be configured to the terminal device by the network device when the connection is released.

In other embodiments, the terminal device may transmit the small data indication information and the radio resource control message via the PUSCH; i.e. multiplexing small data indication information and radio resource control messages on the PUSCH. In this scenario, the size of 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 partial data in the small data through the PUSCH; i.e. multiplexing the small data indication information and part of the data to be transmitted 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; after receiving the PUSCH, the network equipment transmits the small data on the PUSCH through the MsgB/RAR scheduling terminal equipment according to the small data size information indicated in the small data indication information. Therefore, the terminal device may receive scheduling information sent by a network device, where the scheduling information is used to schedule the terminal device to transmit the remaining data to be transmitted.

In this embodiment of the application, the small data indication information may include: first indication information for indicating small data, and/or second indication information for indicating a size of the small data. 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 a Buffer Status Report (BSR) MAC CE. Wherein the first MAC CE is a new MAC CE different from the existing MAC CE; for example, the first MAC CE has a different form from an 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, wherein the third indication information is used for indicating whether the terminal device is allowed to transmit the small data by using the PUSCH.

In a specific implementation, the third indication information may be sent by a network device, and the terminal device may transmit the small data based on a maximum transport block size of a PUSCH in the first type random access only if the indication information indicates that the terminal device is allowed to transmit the small data using the PUSCH.

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

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

The data transmission method provided in the embodiment of the present application is described above for a scenario in which the size of small data is smaller than or equal to the size of the maximum transmission block, and a scenario in which the size of small data is larger than the size of the maximum transmission block and the size of small data is not larger than the maximum data amount that can be transmitted when the small data indication information is transmitted based on the first type random access.

Then, when the network device does not allow the terminal device to transmit the small data by using the PUSCH, or the size of the small data to be transmitted by the terminal device is larger than the maximum data amount that can be transmitted when the small data indication information is transmitted based on the first type random access, the terminal device establishes a radio resource control connection by using the first type random access; and the terminal equipment transmits the small data under the condition of entering a connected state.

As shown in fig. 6, another optional processing flow of the data transmission method provided in the embodiment of the present application includes the following steps:

step S401, the network device receives the small data or the small data indication information through the PUSCH in the first type of random access.

In some embodiments, the network device receives the small data in case that the size of the small data is smaller than or equal to a maximum transport block size of a PUSCH in a first type of random access. When embodied, the network device may receive only the small data through the PUSCH; alternatively, the network device may receive and transmit the small data and the radio resource control message through the PUSCH.

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

Wherein the small data indication information may include: first indication information for indicating small data, and/or second indication information for indicating a size of the small data. 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 different from the existing MAC CE; for example, the first MAC CE has a different form from an existing MAC CE, or carries different information content.

In some embodiments, the network device receiving the small data indication information comprises: the network equipment receives only the small data indication information through the PUSCH; or, the network device receives the small data indication information and the radio resource control message through the PUSCH; or, the network device receives the small data indication information and partial data in the small data through the PUSCH.

The small indication information is also used for indicating the size of data remaining to be transmitted in the small data when the network equipment receives the small data indication information and partial data in the small data through the PUSCH. In this scenario, the method may further include:

step S402, the network device sends scheduling information, and the scheduling information is used for scheduling 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 to allow the terminal device to transmit the small data using the PUSCH.

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