MO-EDT may be applicable to terminals in enhanced coverage, narrowband internet of things terminals, and so on.

When early data transmission EDT is based on random access procedure, the terminal needs to go through at least four steps to send an uplink data. Message 1 (Msg 1), message 2 (Msg 2), message 3 (Msg 3), and message 4 (Msg 4) are sent.

Currently, the third generation partnership project (3rd Generation Partnership Project,3GPP) is under study to boost uplink capacity by orthogonal cover codes (Orthogonal Cover Code, OCC). But the uplink capacity boosting only boosts the capacity of Msg1 and Msg3. Msg2 and Msg4 become bottlenecks that limit the system capacity. To solve this problem, 3GPP is researching an early data transfer EDT method without Msg1/Msg2, i.e. only Msg3 and Msg4. One of the focus of the study on Msg3 is how Msg3 is sent.

Examples: msg3 of the EDT may include one or more of the following: control plane cellular internet of things CIOT function optimized radio resource control RRC early data request message (control plane CIOT EPS/5GS optimization UL RRC Early Data Request message), uplink UL user data transmitted on dedicated transport channel DTCH and UL RRC connection resume request message on common control channel CCCH multiplexed therewith (User plane CIOT EPS/5GS optimization Uplink user data transmitted on DTCH multiplexed with UL RRC Connection Resume Request message on CCCH).

Examples: the terminal may be a Non-terrestrial network (Non-TERRESTRIAL NETWORK, NTN) terminal.

Examples: the resource configuration may be configured by a system message, such as SIB1/SIB2 or a newly defined system information block (System Information Block, SIB).

Sub invention point 1: the CE grading may be two types, CE mode a and CE mode B.

Sub invention point 1.1: the resource configuration may include a reference signal received Power (REFERENCE SIGNAL RECEIVED Power, RSRP) threshold configuration of the CE mode.

Examples: if the RSRP measured by the UE is smaller than the RSRP threshold, the UE is in a CE mode B; otherwise, the UE is in CE mode a.

Sub invention Point 2: the CE level division may also be one or more of CE level 0, CE level 1, CE level 2, CE level 3.

Sub invention point 2.1: one or more RSRP thresholds in CE level 1, CE level 2, CE level 3 may be configured separately from the resource configuration.

Examples: if the RSRP threshold of CE level 3 is configured and the RSRP measured by the UE is less than the RSRP threshold of CE level 3, the UE is at CE level 3; if the RSRP threshold of CE level 2 is configured and the RSRP measured by the UE is less than the RSRP threshold of CE level 2, the UE is at CE level 2; if the RSRP threshold of CE level 1 is configured and the RSRP measured by the UE is less than the RSRP threshold of CE level 1, the UE is at CE level 1; or: if the RSRP threshold for CE level 0 is configured and the RSRP measured by the UE is less than the RSRP threshold for CE level 0, the UE is at CE level 0.

Examples: for narrowband internet of things (Narrow Band Internet of Things, NB-IOT), the UE may measure the RSRP of the anchor carrier reference signal.

Examples: for NB-IOT UE, CE level 0, CE level 1 and CE level 2 can be configured at most. For BL UE or enhanced coverage UE, CE level 0, CE level 1, CE level 2, CE level 3 are configured at most.
