Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

The method for configuring the transport block provided by the embodiment of the application can be applied to an application environment shown in fig. 1. Wherein the terminal 10 is in communication connection with an access network device 20.

The terminal 10 may be, among other things, a device that provides voice and/or other service data connectivity to a user, or a handheld device having wireless connectivity, or other processing device connected to a wireless modem. A wireless terminal may communicate with one or more core networks via a radio access network (Radio Access Network, RAN for short), which may be mobile terminals such as mobile phones (or "cellular" phones) and computers with mobile terminals, e.g., portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile devices that exchange voice and/or data with the radio access network. A wireless Terminal may also be referred to as a system, subscriber Unit (Subscriber Unit), subscriber Station (Subscriber Station), mobile Station (Mobile Station), mobile Station (Mobile), remote Station (Remote Station), remote Terminal (Remote Terminal), access Terminal (Access Terminal), user Terminal (User Terminal), user Agent (User Agent), user equipment (User Device or User Equipment), without limitation.

The access network device 20 may be, but not limited to, a base station (Base Transceiver Station, BTS) in global mobile communications (Global System of Mobile communication, GSM) or code division multiple access (Code Division Multiple Access, CDMA), a base station (NodeB, NB) in wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA), an evolved base station (Evolutional Node B, eNB or eNodeB) in LTE, a relay station or access point, or a base station in a 5G network.

In the wireless communication protocol, after the random access procedure is completed, the target UE can communicate with the access network device to receive and transmit data, and in order to reduce the loss of the terminal of the internet of things and reduce the delay of data transmission, an EDT transmission technology is introduced into NB-IoT and eMTC, so that data can be transmitted through the message 3 in the random access process. At present, the maximum transmission block size of EDT transmission is set by a cell system message, and when a plurality of types of internet of things services exist in a cell, the mode of setting the maximum transmission block size of EDT transmission by the cell system broadcast is not flexible enough due to different lengths of data packets of different types of internet of things, so that certain resource waste can be caused.

Based on the above conventional technology, in the random access process of the target UE, the access network device sends the random access message 2 carrying the EDT transmission configuration indication information to the target UE, and the target UE sends the uplink data packet according to the EDT transmission configuration indication information sent by the access network device, so that different UEs can perform different EDT transmission block configurations according to different EDT transmission configuration indication information, and then send the uplink data packet in the random access message 3, thereby realizing flexible configuration of EDT transmission speed.

It should be noted that the beneficial effects or the technical problems to be solved by the embodiments of the present application are not limited to this one, but may be other implicit or related problems, and particularly, reference may be made to the following description of embodiments.

The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

In one embodiment, as shown in fig. 2, a method for configuring a transport block is provided, and an example of application of the method to the access network device in fig. 1 is described, including the following steps:

In step 201, in the random access process of the target UE, the access network device sends a random access message 2 to the target UE.

Wherein, message 2 carries EDT transmission configuration indication information. The EDT transmission configuration indication information is used for indicating the target UE to send the uplink data packet in the random access message 3 based on the EDT transmission configuration indication information. The uplink data packet is a data packet sent by the target UE to the access network device. The target UE may be an NB-IoT terminal and the access network device may be a base station. Message 2 is a message sent by the access network device to the target UE in the random access process, and message 3 is a message sent by the target UE to the access network device in the random access process.

Alternatively, the length of the EDT transmission configuration indication information may be 1 byte, as shown in fig. 3, where the format of the message 2 is newly defined, and one byte of EDT transmission configuration indication information is added to the original structure of the message 2. The EDT transmission configuration indication information may include maximum transport block configuration information of the EDT transmission, and may also include configuration information of other parameters of the EDT transmission. And after receiving the EDT transmission configuration indication information, the target UE sends an uplink data packet in the message 3 according to the parameters configured in the EDT transmission configuration indication information.

In the random access process of the target UE, the access network equipment sends a message 2 carrying EDT transmission configuration indication information to the target UE, and after receiving the message 2, the target UE acquires the EDT transmission configuration indication information in the message 2, optionally, can judge whether the EDT transmission configuration indication information is effective according to the information carried in the EDT transmission configuration indication information, if so, the target UE still uses the maximum transmission block size configured by the system message to send an uplink data packet in the message 3 according to the maximum transmission block configuration information of the EDT transmission configured in the EDT transmission configuration indication information to send the uplink data packet in the message 3.

In the above embodiment, in the random access process of the target UE, the access network device sends a random access message 2 carrying EDT transmission configuration indication information to the target UE, where the EDT transmission configuration indication information is used to instruct the target UE to send an uplink data packet in a random access message 3 based on the EDT transmission configuration indication information. In this way, in the random access process of the target UE, the access network device sends a random access message 2 carrying EDT transmission configuration indication information to the target UE, and the target UE sends an uplink data packet according to the EDT transmission configuration indication information sent by the access network device, so that different UEs can perform different EDT transmission block configurations according to different EDT transmission configuration indication information, and then send the uplink data packet in a random access message 3, thereby realizing flexible configuration of EDT transmission speed.

Optionally, the EDT transmission configuration indication information includes maximum transport block configuration information, where the maximum transport block configuration information is used to indicate a size of a maximum data packet transmitted by the EDT.

The maximum packet size is the maximum length of the uplink packet sent by the target UE once, and optionally, the maximum transport block configuration information may include 3 bits.

Optionally, the EDT transmission configuration indication information further includes activation information, where the activation information is used to indicate whether to activate the maximum transport block configuration information.

The activation information may be 1 bit, and the activation information may be the most significant bit, and optionally, when the activation information is 0, the EDT transmission configuration indication information is not valid, that is, the configuration maximum transmission block configuration information in the EDT transmission configuration indication information is not valid, that is, the target UE uses the maximum transmission block size configured by the system to perform EDT transmission. And when the activation information is 1, the EDT transmission configuration indication information is effective, namely the maximum transmission block configuration information is effective, and the target UE performs EDT transmission according to the maximum transmission block size configured in the EDT transmission configuration indication information.

Optionally, the EDT transmission configuration indication information further includes reserved bits.

The reserved bits may include 4 bits, and may be used when other parameters in EDT transmission need to be configured, and may be set to 0 when not in use. Alternatively, the EDT transmission configuration indication information is formatted as shown in fig. 4. It is to be understood that fig. 4 is a format of EDT transmission configuration indication information, and the EDT transmission configuration indication information may also be other formats, for example, the activation information may be least significant bits, the upper 4 bits are reserved bits, etc., which is not limited in this application.

In one embodiment, the maximum transport block configuration information of the EDT transmission may be determined according to the size of the data packet actually transmitted, as shown in fig. 5, including:

step 501, the access network device queries a preset database.

The preset database stores the maximum data packet size of EDT transmission corresponding to each of the plurality of UE. The maximum data packet size of EDT transmission corresponding to each of the plurality of UEs is determined by the access network device according to the uplink data packet sent by the history of the target UE, and the steps are as shown in fig. 6, including:

in step 601, the access network device determines the size of the maximum data packet of EDT transmission corresponding to the target UE according to the historical uplink data packet sent by the target UE through the random access message 3.

Optionally, the historical uplink data packet is a data packet sent to the access network device before the target UE does not receive the message 2 carrying the EDT transmission configuration indication information sent by the access network device, in the EDT transmission process, the access network device configures a value of an initial EDT maximum transmission block size in the random access process of the target UE, and sends the value in the SIB2-NB of the system message, after the target UE receives the system message, the target UE accesses the system message according to the parameters configured by the access network device in the system message, and synchronously carries out transmission of the uplink data packet in the message 3, that is, the historical uplink data packet, and according to the historical uplink data packet, the size of the maximum data packet of EDT transmission corresponding to the target UE can be determined, as shown in fig. 7, and the steps include:

In step 701, the access network device determines a first configuration gear currently configured for the target UE from a plurality of configuration gears of the maximum transmission block.

The first configuration gear is the maximum transmission block size of the current configuration of the target UE, and optionally, taking the NB-IoT terminal as an example, the maximum transmission block size has a plurality of configuration gears, and each gear corresponds to the size of a maximum transmission block. The first configuration gear of the target UE is an initial gear issued by the access network equipment in the system message.

In step 702, the access network device determines the size of the maximum data packet of EDT transmission corresponding to the target UE according to the length of the effective data in the historical uplink data packet and the maximum transmission block size corresponding to the first configuration gear.

The access network equipment receives the uplink data packet sent by the target UE through the message 3, demodulates the received uplink data packet, and determines the length of effective data of the uplink data packet after demodulation, wherein the length of the effective data is 0 filled by the maximum transmission block length configured for filling in the deducted uplink data packet, and then the residual data size.

Optionally, whether the length of the effective data of the target UE is smaller than the maximum transmission block size corresponding to the first configuration gear is judged, if so, whether the length of the effective data of the target UE is smaller than the maximum transmission block size corresponding to the next configuration gear of the first configuration gear is continuously judged, wherein the maximum transmission block size corresponding to the next configuration gear of the first configuration gear is smaller than the maximum transmission block size corresponding to the first configuration gear.

Two cases are included at this time, the first case being: and if the length of the effective data is smaller than the maximum transmission block size corresponding to the first configuration gear and is not smaller than the maximum transmission block size corresponding to the next configuration gear of the first configuration gear, taking the maximum transmission block size corresponding to the first configuration gear as the size of the EDT-transmitted maximum data packet corresponding to the target UE.

And if the length of the effective data is smaller than the maximum transmission block size corresponding to the first configuration gear and is not smaller than the maximum transmission block size corresponding to the next configuration gear of the first configuration gear, the length of the effective data is larger than the maximum transmission block size corresponding to the next configuration gear of the first configuration gear, and at the moment, the maximum transmission block size corresponding to the first configuration gear is the proper maximum transmission block size, and the maximum transmission block size corresponding to the first configuration gear is taken as the maximum data packet size of EDT transmission corresponding to the target UE.

The second case is: if the length of the effective data is smaller than the maximum transmission block size corresponding to the first configuration gear and smaller than the maximum transmission block size corresponding to the next configuration gear of the first configuration gear, determining a second configuration gear from the plurality of configuration gears, wherein the length of the effective data is smaller than the maximum transmission block size corresponding to the second configuration gear and larger than the maximum transmission block size corresponding to the next gear of the second configuration gear, and taking the maximum transmission block size corresponding to the second configuration gear as the size of the maximum data packet transmitted by the EDT corresponding to the target UE.

Optionally, if the effective length is smaller than the maximum transmission block size corresponding to the first configuration gear and smaller than the maximum transmission block size corresponding to the next configuration gear of the first configuration gear, whether the effective data length is smaller than the maximum transmission block sizes corresponding to the two configuration gears of the first configuration gear is continuously determined, and if not, the next configuration gear of the first configuration gear is determined to be the second configuration gear. If the effective data length is smaller than the maximum transmission block size corresponding to the two configuration gears in the first configuration gear, continuing to judge whether the effective data length is smaller than the maximum transmission block size corresponding to the three configuration gears in the first configuration gear until the second configuration gear is determined, wherein the effective data length is smaller than the maximum transmission block size corresponding to the second configuration gear and larger than the maximum transmission block size corresponding to the next gear in the second configuration gear, and then taking the maximum transmission block size corresponding to the second configuration gear as the size of the EDT (electronic data transfer) transmitted maximum data packet corresponding to the target UE.

For example, as shown in table 1, taking the first configuration gear of the target UE as 680 and the effective data length as 500 as an example, the procedure of determining the size of the maximum data packet of EDT transmission corresponding to the target UE is illustrated. And if the maximum transmission block size corresponding to the next configuration gear of the first configuration gear is 584, the effective data length 500 is smaller than 584, continuing to judge, if the maximum transmission block size corresponding to the next two configuration gears of the first configuration gear is 504, and if the effective data length 500 is smaller than 504, continuing to judge, if the maximum transmission block size corresponding to the next three configuration gears of the first configuration gear is 408, and if the effective data length 500 is greater than 408, taking the maximum transmission block size 504 corresponding to the next two configuration gears of the first configuration gear as the second configuration gear, and taking the maximum transmission block size corresponding to the second configuration gear as the maximum data packet size of EDT transmission corresponding to the target UE.

Table 1 maximum transport block size configuration gear table

Step 602, the access network device stores the size of the maximum data packet transmitted by EDT corresponding to the target UE in a preset database.

Optionally, the access network device stores the size of the most suitable maximum data packet transmitted by the target UE according to the EDT obtained by the determination in a preset database. The preset database can be deployed in the access network equipment or on a data server.

Step 502, the access network device generates maximum transport block configuration information according to the query result.

And the access network equipment determines the size of the maximum data packet transmitted by the EDT corresponding to the target UE according to the query result, and then generates the configuration information of the maximum transmission block. Optionally, please continue to refer to table 1, wherein the last 3 bits of the EDT transmission configuration indication information represent the maximum transport block configuration information, and the respective bits from 000 to 111 correspond to 8 configuration steps, for example, when the size of the determined most suitable maximum data packet is 504, the maximum transport block configuration information is 010. The middle 4 of the optional EDT transmission configuration indication information is a reserved bit, the highest bit is activation information, and when the activation information is effective, the corresponding relation between different configuration gears and the EDT transmission configuration indication information is shown in a table 1.

In the above embodiment, the maximum transmission block configuration information of EDT transmission is determined according to the size of the historical uplink data packet of the target UE, and the size of the maximum data packet of EDT transmission configured according to this manner more accords with the actual requirement of the target UE, so that resource waste in the EDT transmission process caused by oversized maximum transmission block setting is avoided, and meanwhile, different maximum transmission block configuration information can be set according to different target UEs, so that the transmission block configuration is more flexible.

In one embodiment, as shown in fig. 8, a method for configuring a transport block is provided, and the method is applied to the terminal device in fig. 1 for illustration, and includes the following steps:

in step 801, the target UE receives a random access message 2 sent by the access network device.

Wherein, message 2 carries EDT transmission configuration indication information. From the above, the access network device determines the most appropriate maximum transport block configuration information of the target UE, and then sends the maximum transport block configuration information to the target UE through message 2.

In step 802, the target UE sends an uplink data packet in the random access message 3 based on EDT transmission configuration indication information.

Optionally, the EDT transmission configuration indication information includes maximum transport block configuration information of EDT transmission, and the target UE sends an uplink data packet in the random access message 3 based on the EDT transmission configuration indication information, including: and the target UE sends the uplink data packet in the random access message 3 according to the size of the maximum data packet configured by the maximum transport block configuration information.

The target UE receives the message 2, acquires the EDT transmission configuration instruction in the message 2, determines the maximum transmission block configuration information according to the last 3 bits of the EDT transmission configuration instruction, determines the corresponding maximum transmission block size, namely the size of the maximum data packet, and then sends the uplink data packet in the randomly accessed message 3 according to the size of the maximum data packet.

Optionally, the EDT transmission configuration indication information further includes activation information, where the activation information is used to indicate whether the EDT transmission configuration indication information is effective, and the target UE sends the uplink data packet in the random access message 3 based on the EDT transmission configuration indication information, where the two cases include:

in the first case, in the case that the activation information indicates that the maximum transport block configuration information configuration is activated, the target UE transmits an uplink data packet in the random access message 3 according to the size of the maximum data packet configured by the maximum transport block configuration information.

Optionally, the activation information is the most significant bit of EDT transmission configuration indication information, and when the activation information indicates that the configuration of the maximum transport block configuration information is activated, that is, when the most significant bit is 1, the EDT transmission configuration indication information takes effect, and the target UE sends the uplink data packet in the random access message 3 according to the size of the maximum data packet configured by the maximum transport block configuration information.

In step 903, the access network device determines the size of the maximum data packet of EDT transmission corresponding to the target UE according to the historical uplink data packet sent by the target UE through the random access message 3.

The step of determining the size of the maximum data packet of EDT transmission corresponding to the target UE includes: the access network device determines a first configuration gear currently configured for the target UE from a plurality of configuration gears of the maximum transmission block.

And the access network equipment determines the size of the maximum data packet transmitted by the EDT corresponding to the target UE according to the length of the effective data in the historical uplink data packet and the maximum transmission block size corresponding to the first configuration gear. The specific method comprises the following steps:

and if the length of the effective data is smaller than the maximum transmission block size corresponding to the first configuration gear and is not smaller than the maximum transmission block size corresponding to the next configuration gear of the first configuration gear, taking the maximum transmission block size corresponding to the first configuration gear as the size of the EDT-transmitted maximum data packet corresponding to the target UE.

In step 905, the access network device queries a preset database. The preset database stores the maximum data packet size of EDT transmission corresponding to each of a plurality of UE.

Step 906, the access network device generates maximum transport block configuration information according to the query result.

In step 907, in the random access procedure of the target UE, the access network device sends a random access message 2 to the target UE.

Wherein, message 2 carries EDT transmission configuration indication information. The EDT transmission configuration indication information is used for indicating the target UE to send the uplink data packet in the random access message 3 based on the EDT transmission configuration indication information.
