AI Technical Summary
In existing technologies, when terminals perform early data transmission (EDT), especially mobile-initiated EDT (MO-EDT), Msg2 and Msg4 become system capacity bottlenecks, affecting uplink transmission capacity.
By sending resource configuration information to terminals, terminals with different coverage enhancement CE levels are instructed to determine their CE level and send data and signaling based on that level, thereby improving uplink transmission capacity.
This improves the uplink transmission efficiency of MO-EDT, reduces the transmission steps of Msg1 and Msg2, and enhances the system's reliability and data transmission efficiency.

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.
[0221] 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).

[0223] 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.

[0225] Mobile-Originating Early Data Transmission (MO-EDT) allows selective uplink data transmission followed by downlink data transmission during a random access procedure.
[0226] 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.
[0227] 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).
[0228] Currently, the 3rd Generation Partnership Project (3GPP) is researching ways to increase uplink capacity through orthogonal cover codes (OCC). However, this increase in uplink capacity 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 transmit Msg3.

This disclosure does not limit this.
[0298] In some embodiments, when the terminal 101 is a NB-IOT terminal, the terminal 101 can be configured with CE level 0, CE level 1 and CE level 2, which is not limited in this disclosure.
[0299] In some embodiments, when the terminal 101 is an enhanced coverage terminal, the terminal 101 may be configured with CE level 0, CE level 1, CE level 2, and CE level 3, which is not limited in the present disclosure.
[0300] Step S2103: The terminal 101 determines resources based on the PO associated with the first CE level in the first information.
[0301] In some embodiments, the terminal 101 can determine the frequency domain resources used by the terminal 101 to send the EDT message based on the PO information associated with the first CE level included in the first information, such as the number of frequency domain resources occupied by a physical uplink shared channel opportunity PO; the repetition period of the resources; the starting position of the physical uplink shared channel opportunity PO in the frequency domain; the number of POs of frequency division multiplexing FDM, and other information.
[0302] In some embodiments, the terminal 101 can determine the time domain resources used by the terminal 101 to send the EDT message based on the PO information associated with the first CE level included in the first information, such as the number of time domain resources occupied by a PO; the repetition period of the resources; the start time offset value of the resources, and other information.
[0303] In some embodiments, the terminal 101 may further determine the modulation and coding information used in the EDT message sent by the terminal 101 based on the modulation and coding MCS level associated with the first CE level included in the first information.
[0304] In some embodiments, the terminal 101 may also determine the demodulation information of the EDT message sent by the terminal 101 based on the demodulation reference signal DMRS information on the PO associated with the first CE level included in the first information.
[0305] In some embodiments, when the first information includes uplink subcarrier spacing information associated with the first CE level, the terminal 101 can also determine the transmission resources of the PUSCH channel and perform PUSCH channel processing based on the uplink subcarrier spacing.

[0306] In some embodiments, the terminal 101 may further determine the resource allocation mode of the terminal 101 based on whether the sub-physical resource block sub-PRB allocation mode is adopted in association with the first CE level included in the first information. For example, it may be determined whether to adopt the sub-physical resource block sub-PRB allocation mode when the first CE level is CE mode B, because when the first CE level is CE mode B, the RSRP of the terminal 101 is low, and the number of resource repetition transmissions is large in CE mode B. When the minimum unit of resource allocation of the terminal is a subcarrier within a PRB, in order to reduce resource waste, the sub-physical resource block sub-PRB allocation mode may be selected to reduce the time-frequency domain resources used by the terminal 101. This is not limited in the present disclosure.
[0307] In step S2104, when the maximum allowed transmission block TBS is included in the first information and the size of the media access control MAC protocol data unit PDU carrying the EDT message is less than or equal to the size of the maximum allowed TBS, the terminal 101 sends an EDT message to the network device 102 based on the resources associated with the first CE level.
[0308] In some embodiments, the terms "media access control", "MAC", "Medium Access Control", etc. can be used interchangeably.
[0309] In some embodiments, the terms "protocol data unit", "PDU", "Protocol Data Unit", etc. can be used interchangeably.
[0310] In some embodiments, the network device 102 receives the EDT message sent by the terminal 101 .
[0311] The transmission method involved in the embodiment of the present disclosure may include at least one of steps S2101 to S2104. For example, steps S2101+S2102 may be implemented as independent embodiments, and step S2102 may be implemented as an independent embodiment, etc., but the present disclosure is not limited thereto.
[0312] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.
[0313] In the embodiments of the present disclosure, each step and its optional implementation method can also be implemented independently.
[0314] In this embodiment, the network device sends first information to the terminal. Based on the first information, the terminal determines the first CE level and the resources associated with the first CE level, and includes the maximum allowed transmission block TBS in the first information. When the size of the media access control MAC protocol data unit PDU carrying the EDT message is less than or equal to the size of the maximum allowed TBS, the terminal sends the EDT message to the network device based on the resources associated with the first CE level, thereby improving the uplink transmission capacity and the transmission efficiency of sending the EDT message.
[0315] FIG2B is an interactive diagram of a transmission method according to an embodiment of the present disclosure. As shown in FIG2B , the embodiment of the present disclosure relates to a transmission method for a terminal 101 and a network device 102, the method comprising:
[0316] Step S2201: The network device 102 sends first information to the terminal 101.
[0317] In some embodiments, the first information is used to assist the terminal 101 in determining that the resources used to send the EDT message are competitive resources.

[0319] Step S2203: The terminal 101 determines resources based on the PO associated with the first CE level in the first information.
[0320] For a detailed description of steps S2201 to S2203 , reference may be made to steps S2101 to S2103 in the embodiment shown in FIG2A , which will not be repeated here.
[0321] In step S2204, the terminal 101 determines an OCC sequence based on the OCC code length associated with the first CE level in the first information.
[0322] In some embodiments, after receiving the first information, if the terminal 101 determines that the resources used by the EDT message are competitive resources, the terminal 101 will not be allocated the OCC sequence corresponding to the resources.

[0511] In this embodiment, after the network device sends the first information to the terminal, the terminal determines its own CE level and then sends data and / or signaling to the network device based on the resources associated with the determined CE level, thereby improving the transmission efficiency of data and / or signaling and increasing the uplink transmission capacity.
[0512] The following is an exemplary introduction to the above method.
[0513] This disclosure solves the problem of how the terminal sends EDT Msg3 to improve the uplink transmission capacity by configuring the resources used to send data and / or signaling to the terminal. The optional implementation solutions are as follows:
[0514] The present disclosure relates to a transmission method, which includes:
[0515] Main invention points: User equipment (UE) receives resource configuration for sending Early Data Transmission (EDT) message msg3 sent by a network device, where the resource configuration may include resource configuration for different Coverage Enhancement (CE) levels. The UE determines its own CE level and uses resources corresponding to the determined CE level to send EDT Msg3.
[0516] In an embodiment, the EDT msg3 may include one or more of the following: a control plane CIOT EPS / 5GS optimization UL RRCEarlyDataRequest message; and a user plane CIOT EPS / 5GS optimization Uplink user data transmitted on a dedicated transport channel DTCH and a UL RRC Connection ResumeRequest message multiplexed with the DTCH on a common control channel CCCH.
[0517] Embodiment: The terminal may be a non-terrestrial network (NTN) terminal.

[0519] Sub-invention point 1: The CE level can be divided into two types: CE mode A and CE mode B.
[0520] Sub-invention point 1.1: The resource configuration may include the Reference Signal Received Power (RSRP) threshold configuration of the CE mode.
[0521] Example: If the RSRP measured by the UE is less than the RSRP threshold, the UE is in CE mode B; otherwise, the UE is in CE mode A.
[0522] Sub-invention point 2: The CE level classification can also be one or more of CE level 0, CE level 1, CE level 2, and CE level 3.
[0523] Example: For example, configure CE level 0, CE level 1, and CE level 2. Or configure CE level 0, CE level 1, CE level 2, and CE level 3.
[0524] Sub-invention point 2.1: The resource configuration may include separately configuring one or more RSRP thresholds in CE level 1, CE level 2, and CE level 3.
[0525] Example: 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 in 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 in 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 in CE level 1; or: if the RSRP threshold of CE level 0 is configured and the RSRP measured by the UE is less than the RSRP threshold of CE level 0, the UE is in CE level 0.
[0526] Example: For Narrow Band Internet of Things (NB-IOT), the UE may measure the RSRP of the anchor carrier reference signal.
[0527] Example: For NB-IOT UE, the maximum CE level that can be configured is 0, CE level 1, and CE level 2. For BL UE or enhanced coverage UE, the maximum CE level that can be configured is 0, CE level 1, CE level 2, and CE level 3.
