- EDT Early data transmission
- LTE long term evolved
- EDT has been introduced.
- UE may always remain in idle (idle) state or suspend (suspend) state and inactive (inactive) state to complete the transmission of uplink and/or downlink small data packets.
- the network will configure the size of the largest transport block (TB) allowed to be transmitted by the current network on the system information block (SIB).
- SIB system information block
- the UE judges the amount of data to be transmitted. If it is smaller than the maximum TB size allowed for transmission, the UE can initiate EDT transmission; otherwise, the UE uses the normal connection establishment process and enters the connected state to transmit data.
- Fig. 1 is a schematic flow chart of EDT. As shown in Figure 1, when the cell where the UE initiates EDT is the same as the last serving cell, the base station can directly submit the uplink data to the core network after receiving the connection recovery request and uplink data sent by the UE.
- Preconfigured uplink resource For narrowband Internet of things (narrow band Internet of things, NB-IoT) and enhanced machine-type communication (enhanced machine-type communication, eMTC) scenarios, it introduces the utilization of PUR in idle state PUR method for data transmission.
- the PUR is only valid in the currently configured cell. That is to say, when the UE detects a cell change and initiates random access in the new cell, the UE needs to release the PUR configured in the original cell.
- Fig. 2 is a schematic flow chart of PUR transmission.
- Pre-configured resource (configured grant, CG):
- the resource for UE to transmit uplink data can be based on the dynamic scheduling of the network (indicated by downlink control information (DCI)), or it can be CG resource, which is pre-configured by the network
- DCI downlink control information
- Uplink CG resources can be divided into two types: type 1 and type 2.
- CG type 1 is configured by radio resource control (RRC) parameters, including time domain resources, frequency domain resources, demodulation reference signal (demodulation reference signal, DMRS), open-loop power control, modulation and coding scheme (modulation and coding scheme, MCS), waveform, redundancy version, number of repetitions, frequency modulation, hybrid automatic repeat request (hybrid automatic repeat request, HARQ) process and other parameters.
- RRC radio resource control
- CG type 2 is also configured through RRC parameters, but the activation of the configured CG type 2 resources is indicated by configuring the DCI scrambled by the configured scheduling radio network temporary identifier (CS-RNTI), and configuring time domain resources at the same time , frequency domain resources, DMRS, MCS and other transmission resources and transmission parameters.
- CS-RNTI configured scheduling radio network temporary identifier
- the UE After receiving the high-level configuration, the UE cannot use CG type 2 resources, and must wait until it receives the corresponding DCI activation command and configuration information before it can transmit uplink data.
- the UE determines the HARQ process corresponding to the CG resource according to the network configuration, and starts a timer when the UE completes uplink data transmission using the CG resource corresponding to a certain HARQ process.
- the UE cannot use the CG resource with the same HARQ process to transmit new data, so as to prevent the data in the HARQ buffer (buffer) from being overwritten by other data.
- the timer expires, it indicates that the data transmitted by the corresponding HARQ process has been successfully received by the network.
- Small data transmission In the fifth generation mobile communication technology (the 5th generation, 5G) new air interface (new radio, NR) system, the RRC state is divided into three types, namely RRC idle state, RRC Inactive state and RRC connected state. Among them, the RRC inactive state is a new state introduced by the 5G system from the perspective of energy saving. For the UE in the RRC inactive state, the radio bearer and all radio resources will be released, but the UE side and the base station side retain the UE access context for fast access. To restore the RRC connection, the network usually keeps the UE with infrequent data transmission in the RRC inactive state.
- the UE in the RRC inactive state does not support data transmission.
- the UE needs to restore the connection and release it to the inactive state after the data transmission is completed.
- the SDT technology in the RRC inactive state was proposed in release 17, including the SDT based on the random access process and the SDT based on pre-configured resources (such as CG type 1).
- the common control channel (common control channel, CCCH) message may be an existing RRC recovery request message.
- the SDT also supports subsequent (subsequent) transmission, that is, after the UE completes the first uplink data transmission, it can continue to transmit uplink data or receive downlink data in an inactive state.
- subsequent transmission can be based on network dynamic scheduling or CG.
- the RRC resume request message includes inactive radio network temporary identifier (I-RNTI), resume medium access control identify (Resume MAC-I) and resume cause (Resume cause) , where I-RNTI is the UE identifier, which is used by the base station to find the UE context according to the I-RNTI; Resume MAC-I is used by the base station to authenticate the UE; Resume cause is used to indicate the reason why the UE initiates the connection request.
- I-RNTI is the UE identifier, which is used by the base station to find the UE context according to the I-RNTI
- Resume MAC-I is used by the base station to authenticate the UE
- Resume cause is used to indicate the reason why the UE initiates the connection request.
- the first uplink transmission needs to include an RRC recovery request message, which is used by the base station to determine the UE identity, find the UE access context, and authenticate the UE identity. Subsequent transmissions need to be performed after the network successfully authenticates the UE.
- RRC recovery request message which is used by the base station to determine the UE identity, find the UE access context, and authenticate the UE identity. Subsequent transmissions need to be performed after the network successfully authenticates the UE.
- the resources used for the first uplink data transmission are CGs, and the resources used for subsequent data transmissions can be either CGs or resources based on dynamic scheduling. If the data transmitted by the UE on the CG resource for the first time has not been successfully received by the network, the UE may transmit the remaining data on the next CG resource, which will cause the network to receive the subsequent data without authenticating the UE. data.

- the terminal device 302 sends first uplink data on the first CG resource, where the first uplink data includes first information, and the first information is used for identity authentication of the terminal device 302 .
- the terminal device 302 After the first duration, the terminal device 302 sends the second uplink data on the second CG resource. It can be seen that the terminal device 302 sends the first uplink data on the first CG resource, and then sends the second uplink data on the second CG resource after the first duration.
- the setting of the first duration ensures that the terminal device 302 can send the second uplink data only after the network device 301 authenticates the terminal device 302 . In the SDT process based on the CG resource, the problem that the network receives subsequent data before performing identity authentication on the UE is avoided.
