Embodiment Construction

[0054] In the prior art, the NB-IoT device finds that the coverage duration of the current NTN cell still has 10ms remaining, and it needs to transmit a data packet every 1ms. Under the current signal strength condition, the transmission of a data packet needs to be repeated 20 times, then The NB-IoT device determines that 20 repeated transmissions cannot be completed within 10ms, so it does not start transmission in the current NTN cell, but waits until the next NTN cell covers itself before starting transmission.

[0055] It can be seen that the above solution will result in that in the coverage time period of an NTN cell, there is no NB-IoT device transmitting data for part of the time, resulting in a waste of resources.

[0056] In the embodiment of the present invention, after the anchor cell for data transmission and the transmission time window are determined, when it is detected that the number of transmissions M of the target data transmission at the end of the current...

Abstract

The invention discloses a data transmission method, a cell residence method, a device and a medium. The data transmission method comprises the following steps: determining an anchor cell for data transmission; and performing data transmission through the anchor cell. According to the scheme, resource waste in the coverage time period of the NTN cell can be avoided.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a data transmission method and a cell camping method, device and medium. Background technique [0002] NB-IoT type devices can transmit data through the wireless network, so as to exchange information with the corresponding NB-IoT service server. In the existing protocol, the NB-IoT device is connected to a terrestrial wireless network (Terrestrial access Network, TN), and naturally does not need to support mobility, so its design is very simple and does not support handover procedures. [0003] However, with the gradual popularization of NB-IoT devices, there are NB-IoT devices deployed in the wild. These areas may not have TN coverage, so data can only be transmitted through a non-terrestrial access network (NTN). The biggest difference between the TN network and the NTN network is that the base stations used in the TN network are usually fixed on t...
