Option 2: Inactive data transfer

If the network side device receives the BSR and the buffer size does not exceed the threshold (or is less than the threshold), the network side device performs an uplink grant UL grant on the user equipment. Specifically, the user equipment receives the UL grant for data transmission, and may further transmit the BSR, and then the network side device confirms the data reception. For example, the network side device confirms the data reception by using the underlying ACK signaling.

In this embodiment, if the network side device receives the data, when the network side device needs to perform the context update, the network side device is in the information of the layer 2 corresponding to the information carrying the user equipment identification information. Carry an additional RRC indication; or

If the network side device receives the data and the BSR, and the buffer size is greater than the threshold, the network side device additionally carries an RRC indication in the information of the layer 2 corresponding to the information carrying the user equipment identification information; or

If the network side device receives the BSR and the buffer size is smaller than the threshold, when the network side device needs to perform the context update, the network side device is in the layer 2 information corresponding to the information carrying the user equipment identification information. An additional RRC indication is carried.

In this embodiment, the network side device can feed back, to the user equipment, the data transmission and/or the connection recovery or establishment confirmation for the information carrying the user equipment identification information according to the received data and/or the BSR. The signaling design can be implemented to implement the transmission of partial type data (such as low overhead fast INACTIVE small data) with low overhead and fast completion of the user equipment in an inactive state.

Embodiment 2

Referring to FIG. 2, a data transmission method is shown, and the specific steps are as follows:

Step 201: The user equipment sends a request message to the network side device, and sends one or more of the data and the buffer status report BSR to the network side device, where the request message carries at least user equipment identification information.

The request message may also carry the verification information of the user equipment.

An acknowledgment of the restoration or establishment of the information connection carrying the user equipment identification information fed back by the data and/or BSR.

For example, the request message may be an RRC Connection Resume Request, and the RRC Connection Resume Request may carry an ID of the user equipment and a message authentication code, where the message authentication code is used to verify the user equipment, for example, the message authentication code is MAC. -I (Message Authentication Code used for data Integrity of signaling messages) information.

In this embodiment, if the network side device receives the BSR and the buffer size is smaller than the threshold, when the user equipment receives the UL grant message, the user equipment performs data transmission to the network side device, where the user The device receives the information that is sent by the network side device and carries the information about the user equipment identification information for data transmission.

Embodiment 3

The UE first tells the gNB UE ID and MAC-I information (for authentication of the user equipment UE), and may bring data (Data) or Buffer Status Report (BSR), where UE ID and MAC-I The delivery can be based on the existing RRC Connection Resume Request process.

The above data and cache status report can share transmission resources, for example, two MAC sub-headers need to be placed. In this way, while the gNB receives the data, it can flexibly further obtain the next request of the data transmission (the amount of data to be transmitted in the cache).

Solution 1: The UE performs data transmission in an inactive state.

If the gNB only receives the data, the UE is fed back with the UE ID for confirmation (eg, the acknowledgment message is delivered through the MAC layer); the data may also carry a further buffer status, which may indicate the required buffer size of the UE.

Option 2: The UE performs data transmission in an inactive state.

If the gNB receives the BSR (cache status report) and the buffer size does not exceed a threshold (or is less than a threshold), the gNB performs uplink grant (UL Grant), and the UE receives the UL Grant for data transmission, and can further transmit the BSR. The gNB confirms the data reception, for example, confirms the data reception by ACK signaling.

Option 3:

If the gNB receives the BSR and the buffer size exceeds a threshold (or is not less than a threshold), the gNB restores the RRC Connection Resume of the user equipment. The UE confirms the RRC Connection Resume Complete (Connect) and enters the connected state (Connected), and uploads the BSR. The BSR includes DRB (Data Radio Bearer) information, followed by connection state related scheduling and data transmission.

It should be noted that the occurrence of any of the foregoing scenarios 1, 2, and 3, or the occurrence of any combination, is within the scope of the present application.
