[0212] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0213] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0215] The following embodiments of the present disclosure may be applied to the communication system shown in Figure 1, or a portion of the entities, but are not limited thereto. The entities shown in Figure 1 are illustrative only. The communication system may include all or part of the entities shown in Figure 1, or may include other entities outside of Figure 1. The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, either directly or indirectly, and may be wired or wireless.

[0216] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods.

[0217] Mobile-Originating Early Data Transmission (MO-EDT) allows selective uplink data transmission followed by downlink data transmission during a random access procedure.

[0218] MO-EDT is triggered when the upper layer has requested to establish or resume a Radio Resource Control (RCC) connection for mobile-originated data and the uplink data size is less than or equal to the Transport Block (TB) size indicated in the system information. When using user-plane Cellular Internet of Things (CIoT) function optimization, MO-EDT may not be used for data on the control plane. MO-EDT can be applicable to terminals in enhanced coverage and narrowband IoT terminals, etc.

[0219] When Early Data Transmission (EDT) is based on the random access process, a terminal must go through at least four steps to send uplink data: sending message 1 (Msg1), receiving message 2 (Msg2), sending message 3 (Msg3), and receiving message 4 (Msg4).

[0220] Currently, the 3rd Generation Partnership Project (3GPP) is researching ways to increase uplink capacity through orthogonal cover codes (OCC). However, this uplink capacity increase only improves the capacity of Msg1 and Msg3. Msg2 and Msg4 become bottlenecks that restrict system capacity. To address this issue, 3GPP is researching early data transmission (EDT) methods that eliminate Msg1 and Msg2, meaning only Msg3 and Msg4. A key focus of Msg3 research is how to provide uplink resources for sending Msg3.
