Description

Method for transmitting data, communication device and network equipment

This application claims the priority of a Chinese patent application filed with the Chinese Patent Office on June 24, 2020, the application number is 202010589538.6, and the application title is "a method of data transmission, communication device and network equipment", the entire content of which is by reference Incorporated in this application.

Technical field

The field of communication technology of this application, in particular, relates to a method, communication device, and network equipment for transmitting data.

Background technique

Random access is a basic and important process in the Long Term Evolution (LTE) system and the New Radio (NR) system. Its main purposes are as follows: 1. Establish uplink synchronization; 2. The terminal allocates a unique cell radio network temporary identifier (Cell Radio Network Temporary Identifier, C-RNTI for short), and requests the network to allocate uplink resources to the terminal. Therefore, random access is not only used for initial access, but also for new cell access during handover, access after radio link failure, resumption of uplink synchronization when there is uplink/downlink data transmission, and uplink shared channel (uplink shared channel, UL-SCH for short) resource request, etc. After completing the random access process, the terminal can enter the connected state and establish a radio resource control (Radio Resource Control, RRC for short) connection with the base station to perform data transmission with the network.

In many application scenarios, there may be some data packets with a size smaller than a preset threshold that need to be sent. In the prior art, in order to reduce signaling overhead and save terminal power consumption, Early Data Transmission (EDT) is proposed. According to the mechanism, a terminal in an idle state can perform an uplink data transmission during random access, or configure a pre-configured uplink resource (PUR) for the terminal when the last RRC connection is released, Then use PUR to transmit such data packets. However, in both cases, the terminal can only perform uplink data transmission once, and only when the size of the data to be transmitted on the terminal side is less than or equal to the size of the largest data block (Transport Block Size, TBS) of EDT or PUR. Use EDT or PUR transmission. Otherwise, the terminal must enter the connected state through the RRC connection recovery process before sending the data to be transmitted.

Summary of the invention

The technical problem to be solved by the embodiments of the present application is to provide a data transmission method, communication device and network equipment to solve the problem of high signaling interaction overhead and high terminal power consumption when the terminal transmits multiple data packets in the inactive state.

detailed description

The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

The terms "including" and "having" in the specification and claims of this application and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units not listed, or optionally includes Other steps or units inherent in these processes, methods, products or equipment.

In the Long Term Evolution (LTE) system and the New Radio (NR) system, the base station and the terminal can complete random access through four steps of msg1-msg4 information exchange. For example, a contention-based random access scenario includes the following steps: msg1, the terminal sends a random access preamble (Preamble); msg2, the base station sends a random access response message; msg3, the terminal sends msg3, the content of msg3 and the content of random access There are several types of trigger events. For example, the content of msg3 during the initial access is a radio resource control (Radio Resource Control, RRC) connection request, and the content of msg3 when the connection is reestablished is an RRC connection reestablishment request, etc.; msg4, the base station sends a contention resolution message . So as to complete the random access process.

In addition, in order to reduce the access delay of the terminal, a two-step random access method is proposed. The terminal sends an msgA message to the base station, and the base station responds to the msgB message. Only one information exchange is required between the terminal and the base station to complete Random access.

In the above and possible random access scenarios in the future, the state of the terminal includes the following:

In the connected state, a radio resource control (Radio Resource Control, RRC) connection is established between the terminal and a radio access network (Radio Access Network, RAN) device such as a base station. When the terminal is in the connected state, the terminal device saves its own context information and can perform cell handover based on RAN control.

In the idle state, there is no RRC connection between the terminal device and the RAN device, and the context information is no longer stored in the terminal device and the RAN device. When the terminal device is in an idle state, the terminal device releases its own context information and can perform cell-based reselection.

In the inactive state, the terminal saves its own context information and can perform cell-based reselection operations. At the same time, the connection information of the terminal is stored in the anchor RAN device. The connection information of the terminal includes the context information of the terminal and the core network connection. . When the terminal is in the inactive state, the terminal saves the management area information configured by the anchor RAN device, and the terminal needs to notify the anchor RAN device when it moves out of the management area corresponding to the management area information.

The inactive state can also be called the third state, light connection state, suspend state, and so on.

When the terminal is in the inactive state, the RRC connection between the terminal and the RAN device can be restored through an RRC connection resume (Resume) message.

Among them, in the idle state or inactive state, if the terminal has multiple data packets whose size is less than the preset threshold to be transmitted, the terminal can switch to the connected state for continuous transmission, or perform the random access process repeatedly (only each time Transmit an uplink data packet and a downlink data packet), which will lead to cumbersome information interaction and higher power consumption of the terminal. Therefore, this application proposes a data transmission method to better realize the transmission of multiple data packets.

For ease of description, the embodiments of the present invention are described in terms of LTE systems or NR systems. The implementations in the embodiments of the present invention are also applicable to other existing communication systems and future higher-level communication systems such as 6G and 7G. The embodiment of the present invention does not make any limitation.

The data transmission method and device of the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

Information and request pre-configured resources from the base station to send one or more data packets. For ease of description, the embodiment of the present application only shows one terminal 20. In an actual scenario, the number of terminals 20 can be one or more. Some terminals can also be used as relay devices, and other terminals can relay messages. It is also possible to form a user group with the terminal, which is not limited in the embodiment of the present application.

Please refer to FIG. 2. FIG. 2 is a schematic flowchart of a method for transmitting data according to an embodiment of the application; it includes the following steps:

S201: The terminal sends instruction information to the base station.

S202: The terminal sends the one or more data packets.

In a possible implementation manner, the indication information may be used to instruct the terminal to send transmission information of one or more data packets when in an inactive state.

The indication information may be used to indicate that there is a transmission demand for one or more data packets when the terminal is in an inactive state; including:

Case 1-1: It is indicated that the number of times the terminal needs to perform data packet transmission is once;

Case 1-2: Indicate that the number of times the terminal needs to perform data packet transmission is greater than one and less than the maximum number of transmission times of the terminal in the inactive state;

Case 1-3: It is indicated that the number of times the terminal needs to perform data packet transmission is greater than or equal to the maximum number of transmission times of the terminal in the inactive state.

When the number of transmissions is once, the base station can configure the terminal to complete the transmission of the data packet in the inactive state, and the terminal can use the first pre-configured resource requested by the terminal during the random access process, such as PUR resource or CG resource, or through the random access process Carry the data packet to be transmitted in msg3 to complete the transmission of the data packet.

When the number of transmissions is greater than one and less than the maximum number of transmissions, the terminal can initiate a pre-configured resource request to the base station. After the base station allocates the second pre-configured resource to the terminal, the first pre-configured resource (such as PUR resource or CG resource) and the first pre-configured resource are used. Two pre-configured resources (such as PUR resources or CG resources), or use the first pre-configured resources or the second pre-configured resources to complete the transmission of the data packet.

When the number of transmissions is greater than the maximum number of transmissions in the inactive state, the base station can configure the terminal to switch to the connected state and complete the data packet transmission in the connected state. This is because data packets cannot be transmitted indefinitely in the inactive state. When the data packets are too large or too many, the transmission in the inactive state does not increase the power consumption of the terminal, so it can directly enter the connection. State transmission.

For the maximum number of transmissions, the terminal may first obtain the maximum number of transmissions of a data packet in the inactive state before step S201.

The maximum number of transmissions may be configured by the base station and issued to the terminal; or

The maximum number of transmissions may be requested by the terminal to be configured by the base station and issued to the terminal; or

The maximum number of transmissions can be pre-configured in the system message.

In another possible implementation manner, the indication information is used to indicate the state that the terminal is in when transmitting the one or more data packets, and the state includes an inactive state and a connected state. State; the indication information is used for:

Case 2-1: Instruct the terminal to expect data transmission in the inactive state;

Case 2-2: Indicate that the terminal expects to perform data transmission in the connected state.

When the terminal expects to transmit data packets in the inactive state, it means that the number of data packets that need to be transmitted at this time is less than the maximum number of transmissions of the terminal in the inactive state. Therefore, the base station can configure the terminal to complete the data packet in the inactive state. transmission.

When the terminal expects to transmit data packets in the connected state, it means that the number of data packets to be transmitted at this time is greater than or equal to the maximum number of transmissions, so the base station can configure the terminal to complete the data packet transmission in the connected state.

The indication of the transmission state reflects the state when the terminal in the inactive state expects to transmit the data packet, so that the base station can flexibly make instructions and control the state transition of the terminal, which is conducive to the reasonable transmission of data packets and the control of terminal power consumption.

In another possible implementation manner, the indication information is used to indicate that the terminal has a transmission requirement for one or more data packets when the terminal is in the inactive state, and the indication information is used to indicate the expected presence of the terminal. The state that the terminal is in when the one or more data packets are transmitted, and the state includes an inactive state and a connected state;

The instruction information is used for:

Case 3-1: Indicate that the number of times the terminal needs to perform data packet transmission is once, and indicate that the terminal expects to perform data packet transmission in the inactive state; at this time, the base station can configure the terminal to complete the data packet transmission in the inactive state For transmission, the terminal can use the first pre-configured resource such as PUR resource or CG resource allocated by the network device when the last RRC connection is released, or carry the data packet to be transmitted in msg3 through a random access process to complete the data packet transmission.

Case 3-2: Indicate that the number of times that the terminal needs to perform data packet transmission is greater than one and less than the maximum number of transmission times of the terminal in the inactive state, and indicate that the terminal expects to perform data packet transmission in the inactive state; The terminal can initiate a pre-configured resource request to the base station. After the base station allocates the second pre-configured resource to the terminal, the first pre-configured resource (such as PUR resource or CG resource) and the second pre-configured resource are used, or the first pre-configured resource is used The resource or the second pre-configured resource completes the transmission of the data packet.

Case 3-3: Indicate that the number of times the terminal needs to perform data packet transmission is greater than or equal to the maximum number of transmission times of the terminal in the inactive state, and indicate that the terminal expects to perform data packet transmission in the connected state. At this time, the base station can configure the terminal to switch to the connected state, and complete the data packet transmission in the connected state.

It should be noted that the indication information sent by the terminal can be used by the base station as a reference when deciding the state transition of the terminal, and the base station can also make a comprehensive decision based on any one or more of the following information:

Current resource usage, resource request priority or service priority of other terminals, channel conditions with the terminal, etc.

There may be multiple ways to carry the indication information. For example, the indication information may be indicated by a preamble sent by the terminal to the base station;

In the existing NR system, there are 64 preambles, which can be grouped. For example, they can be divided into three groups, corresponding to the three situations that they may indicate. For example, the 1-20 preambles can be used as a group. Indicate situation 1-1 or 2-1 or 3-1; 21-44 are used to indicate situation 1-2 or 3-2, and 45-64 are used to indicate situation 1-3 or 2-2 or 3- 2.

In the embodiment of this application, the terminal can inform the network side of its own transmission information in the inactive state, which is conducive to the network side’s control of the terminal’s transmission state and related resource configuration, and realizes the data transmission of the terminal in the inactive state, which is beneficial to the terminal. Reduction of power consumption.

When instructed by msg3 or msgA, two connection recovery cause values can be added to the existing connection recovery cause (resume cause) value: oneshort-data (indicating that there is a small data packet to be transmitted), multishort-data( Indicates that there are multiple small data packets to be transmitted). For details, please refer to FIGS. 3 and 4, where FIG. 3 is a schematic flowchart of a method for carrying indication information according to an embodiment of this application;

In Figure 3, the flow of the four-step random access method is shown:

S301: The terminal sends a random access request (msg1) to the base station;

S302: The base station sends a random access response (msg2) to the terminal;

S303: The terminal sends a connection recovery request (msg3) to the base station;

Carry the newly-added connection recovery reason value such as oneshort-data or multishot-data;

To indicate to the base station the transmission information of the terminal in the inactive state.

S304: The base station sends a conflict resolution message (msg4) to the terminal.

In this way, the indication information can be carried through msg3 to inform the base station terminal of the transmission information.

In Figure 4, the flow of the two-step random access method is shown:

S401: The terminal sends msgA to the base station, carrying a random access preamble and an RRC connection recovery request message, etc., wherein the RRC connection recovery request message can carry a newly-added connection recovery reason value such as oneshort-data or multishot-data; Indicate the transmission information of the terminal in the inactive state to the base station.

S402: The base station sends msgB to the terminal.

In addition to using the existing reserved bits for indicating the connection recovery reason value to carry the indication information, it is also possible to modify the existing used bits for the connection recovery reason value to carry the indication. Information, or the reserved bits in msg3 or msgA can be used to carry and indicate the indication information.

For example, the indication information may be indicated by the first bit in msg3 or msgA in the random access process;

Alternatively, the indication information may also be indicated by the first bit and the second bit in msg3 or msgA in the random access process.

When the first bit is used to indicate, for example, "1" can be used to indicate that multiple data packets need to be transmitted, and "0" can be used to indicate that one data packet needs to be transmitted; or, "0" can also be used to indicate that multiple data packets need to be transmitted. Data packet, use "1" to indicate that a data packet needs to be transmitted. Since 1 bit can only indicate two cases, the aforementioned cases 1-1, 1-2, and 1-3 can be selected as needed. For example, for the case 1-3 when the maximum number of transmissions is reached, it belongs to the connected state. If you need to solve the transmission indication in the inactive state, you can use "1" to represent case 1-2, and "0" to represent case 1-1. For another example, for the case 1-1 where there is only one transmission, it is a single transmission and there is no state transition. If you need to solve the transmission instruction under the state transition, you can use "1" to represent case 1-2 and "0" to represent Situation 1-3. The indication methods of case 2-1, 2-2, case 3-1, 3-2, and 3-3 are similar, and will not be repeated here.

When using the first bit and the second bit to indicate:

For example, the first bit is 0 and the second bit is 1: It can indicate that there is only one data packet to be transmitted, and a data transmission is required, and the terminal expects to transmit in the inactive state (case 1-1 or 2-1 or 3- 1).

The first bit is 1, the second bit is 0: it can indicate that the number of data packets transmitted is greater than 1 and less than the maximum number of transmissions. The number of transmissions is the number of data packets. The terminal expects to transmit in the inactive state (case 1- 2 or 2-1 or 3-2).

The first bit is 1, and the second bit is 1: It can indicate that the number of data packets transmitted is greater than or equal to the maximum number of transmissions. The number of transmissions is the number of data packets. The terminal expects to transmit in the connected state (cases 1-3 Or 2-2 or 3-3).

The first bit is 0, the second bit is 0: it can be reserved.

It should be noted that the values of the above bits are only examples. In actual use, any combination and configuration can be used as needed to indicate the various situations described above.

After the terminal finishes sending the indication information, if there is a transmission demand for multiple data packets, it may send a pre-configured resource request to the base station to obtain pre-configured resources for sending multiple data packets. Please refer to Figure 5 and Figure 6 for the specific process.

Figure 5 is a schematic flowchart of another data transmission method provided by an embodiment of this application; the terminal can apply to the base station for the first pre-configured resource during the last RRC connection. Pre-configured resources, so that when the terminal enters the inactive state after the connection is released, the first pre-configured resource can be used to transmit data once. In order to realize the sending of multiple data packets, the terminal may apply to the network device for the second pre-configured resource, as shown in FIG. 5, which includes the following steps:

S501: The base station sends a radio resource control (Radio Resource Control, RRC for short) release message to the terminal to configure a first pre-configured resource for the terminal. Such as PUR resources or CG resources.

S502: The terminal verifies that the first TA is valid, that is, confirms that the uplink synchronization is performed, and the current PUR resource or CG resource can be used.

S503: The terminal sends an RRC connection recovery request message to the base station, which carries the first data packet of the multiple data packets and pre-configured resource request information, where the pre-configured resource request information is used to request the base station to allocate the terminal for sending the The second pre-configured resource of the data packets other than the first data packet among the multiple data packets;

Wherein, the second pre-configured resource may be a PUR resource or a CG resource.

S504: The base station sends an RRC connection release message to the terminal, and at the same time configures a second pre-configured resource for the terminal.

S505: The terminal uses the first pre-configured resource and the second pre-configured resource to transmit the other data packet, or uses the second pre-configured resource to transmit the other data packet.

In step S503, the pre-configured resource request information includes:

Before step S503, the terminal may also first obtain the maximum pre-configured number of the pre-configured resources.

The maximum pre-configured number of pre-configured resources may be configured by the base station and issued to the terminal; or

The number of second pre-configured resources acquired by the terminal may be the same as or different from the number of data packets that need to be transmitted. The terminal can use the first pre-configured resource to transmit other data packets, or use the second pre-configured resource to transmit other data. Packets, the first pre-configured resource and the second pre-configured resource can also be used to transmit data packets. When the number of configured resources is less than the number of data packets, these resources can be used to periodically transmit data packets. For example, two pre-configured resources are used to transmit four data packets twice.

In step S504, the base station may also send a second TA to the terminal at the same time when configuring the second pre-configured resource. The second TA is used for uplink synchronization when the terminal uses the pre-configured resource to transmit data packets.

Sending the first data packet and the pre-configured resource request information through the first pre-configured resource can realize the acquisition of the second pre-configured resource, and then can realize the transmission of multiple data packets in the inactive state, and the terminal does not need to enter the connected state Thereby, the efficiency of information exchange and data transmission is improved, and the power consumption of the terminal is reduced.

When the first TA is invalid, the uplink synchronization cannot be achieved. At this time, even if the terminal applies for the first pre-configured resource, it cannot be used. In this case, refer to FIG. 6, which is another example provided by the embodiment of this application. A schematic flow diagram of a method for transmitting data; including the following steps:

S601: The base station sends a radio resource control (Radio Resource Control, RRC for short) release message to the terminal to configure a first pre-configured resource for the terminal. Such as PUR resources or CG resources.

S602: The terminal verifies that the first TA is invalid, that is, uplink synchronization cannot be achieved, and the current PUR resource or CG resource cannot be used.

S603: The terminal sends msg1 to the base station;

S604: The base station sends msg2 to the terminal;

S605: The terminal sends msg3 to the base station;

Send msg3 through the uplink authorized resource (UL grant) allocated in msg2, msg3 carries the first data packet among multiple data packets and pre-configured resource request information, and the pre-configured resource request information is used to request the base station to be a terminal A second pre-configured resource used for sending data packets other than the first data packet among the multiple data packets is allocated; the second pre-configured resource may be a PUR resource or a CG resource.

S606: The base station sends an RRC connection release message to the terminal to configure the second pre-configured resource for the terminal.

S607: The terminal uses the second pre-configured resource to transmit the other data packet.

The above steps S603-S605 correspond to msg1-msg3 in the four-step random access method respectively. The method shown in the embodiment of this application is also applicable to the scenario of the two-step random access method. For example, the steps in this application can be changed S603-S605 are replaced with msgA in the two-step random access method, and msgA carries the first data packet among multiple data packets and pre-configured resource request information. So as to complete the transmission of multiple data packets in the inactive state.

In this embodiment, the terminal may actively send pre-configured resource request information or other request information used to indicate the requirements of the terminal to the base station to request the base station to allocate the second pre-configured resource to the terminal. In addition, the base station can also allocate the second pre-configured resource to the terminal according to the instruction information sent by the terminal, or the base station can actively monitor the state of the terminal to determine the transmission demand of the terminal, and then allocate the second pre-configured resource to the terminal. Resources, etc., this application does not make any restrictions.

For the terminal, it may first send the indication information to the base station and then apply for the second pre-configured resource, or it may not send the indication information, and directly apply for the second pre-configured resource from the base station according to the transmission requirements of multiple data packets it exists.

For details, refer to FIG. 7. FIG. 7 is a schematic flowchart of another data transmission method provided by an embodiment of the application; including:

S701: If a terminal in an inactive state has a transmission requirement for multiple data packets, the terminal sends the first one of the multiple data packets through the pre-configured first pre-configured resource or through msg3 or through msgA. When data packets are sent, the pre-configured resource request information is sent to the network device, and the network device is requested to allocate the terminal for sending the first data packet of the plurality of data packets except the first data packet. 2. Pre-configured resources;

S702. The terminal sends the other data packet through a pre-configured resource, where the pre-configured resource includes the first pre-configured resource and the second pre-configured resource, or the pre-configured resource includes the second pre-configured resource. Configure resources.

When the communication device is a terminal, FIG. 10 shows a simplified schematic diagram of the structure of the terminal. It is easy to understand and easy to illustrate. In FIG. 10, the terminal uses a mobile phone as an example. As shown in Figure 10, the terminal includes a processor, a memory, a radio frequency circuit, an antenna, and an input and output device. The processor is mainly used to process the communication protocol and communication data, and to control the terminal device, execute the software program, and process the data of the software program. The memory is mainly used to store software programs and data. The radio frequency circuit is mainly used for the conversion of baseband signal and radio frequency signal and the processing of radio frequency signal. The antenna is mainly used to send and receive radio frequency signals in the form of electromagnetic waves. Input and output devices, such as touch screens, display screens, keyboards, etc., are mainly used to receive data input by users and output data to users.
