Description

Signal transmission method, device and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a signal transmission method, apparatus, and storage medium.

Background

Compared with the fourth generation mobile communication (the 4th generation mobile communication,4G, 5G) mobile communication, the New air interface (NR) system needs to support high-frequency band, large bandwidth and large-scale antenna technology, and the power consumption of the fifth generation mobile communication (the 5, th generation mobile communication, 5G) base station is improved to 2-3 times of that of the 4G base station while the system performance is improved. The power consumption is a main index of expenditure of operators, and according to the data of operators, the operation cost of the power consumption in the mobile network accounts for about 23% of the total operation cost, so that the mobile network becomes a heavy burden for wide deployment of the 5G network, and the application of the mobile network in the vertical industry field and the large-scale popularization of the 5G terminal are limited due to the power consumption problem.

In some scenarios, the terminal/User Equipment (UE) needs to maintain multiple radio links simultaneously, resulting in higher power consumption of the base station and the terminal. One cell, e.g., a primary cell (PRIMARY CELL, pcell), provides basic coverage. When the data rate requirements of the terminal dynamically change, for example, the data rate is from high to low, or from low to high, other cells, such as Secondary cells (scells), need to be considered for activation or deactivation, thereby saving power consumption of the network and the terminal.

In the prior art, scell requires periodic transmission of synchronization blocks (Synchronization Signal Block, SSB) during deactivation and by configuring a temporary time-frequency tracking signal (Temporty TRS) for reducing the delay of Scell activation, thereby reducing the power consumption of the terminal and base station. But the periodic transmission of SSBs by the Scell during deactivation still causes no small power consumption.

Detailed Description

In some scenarios, the terminal needs to maintain multiple wireless links at the same time, resulting in higher power consumption of the base station and the terminal. The activation and deactivation mechanisms of the secondary cell group (Secondary Cell Group, SCG) are introduced in the R17 standard. And by periodically transmitting SSB during deactivation and combining with configuration of temporary TRS, the time delay of Scell activation is reduced, thereby reducing the power consumption of the terminal and the base station. But the periodic transmission of SSBs by the Scell during deactivation still causes no small power consumption.

In order to solve the technical problem while reducing the activation time delay of the Scell, the embodiment of the application provides a signal transmission method for synchronizing a terminal and the Scell based on a configuration message of the Pcell, which can reduce the activation time delay of the Scell and prevent the Scell from sending SSB during the deactivation period, thereby reducing the power consumption of a base station and the terminal.
