Patent Description:
In a new radio system, especially when a communication frequency band is in frequency range <NUM> (above <NUM>), since a high-frequency channel attenuates rapidly, it is necessary to take use of beam-based transmission and reception to ensure a coverage area.

Currently, a base station uses one panel to send data to a user terminal, and a user terminal uses one panel to receive the data sent by the base station to the user terminal. However, one panel can only point to one beam direction at one time, resulting in insufficient space diversity.

In the related art, one panel can only point to one beam direction at the same time, so the space diversity is not enough. When a base station has multiple transmission reception points (TRPs) and each TRP has one or more sending panels, or the base station has only one TRP and the TRP has multiple sending panels, the base station can use the multiple panels at the same time to send data to the same user terminal. The multiple panels may belong to the same TRP or different TRPs. In this case, different panels have different sending directions, and the user terminal can also use different panels to receive data, so as to achieve better spatial diversity and improve the reliability of data transmission. However, even if the terminal has multiple panels, factors such as whether the multiple panels can be used at the same time and how long time it takes to switch between the multiple panels, will affect communication performance between the base station and the terminal, resulting in resource waste. Currently, the technical problem of how the base station knows whether the multiple panels of the terminal can be activated and used at the same time is unsolved.

In order to solve the above problems, the embodiments of the disclosure provide a data transmission method, applied to a first device. The method includes: sending information on a panel capability level supported by the first device to a second device, in which the information on the panel capability level indicates whether two or more panels of the first device can be activated and used simultaneously; receiving control information sent by the second device, in which the control information includes a target activated panel selected from panels of the first device by the second device, and an identifier of a beam corresponding to a target used panel selected from the target activated panel by the second device; and performing data transmission with the second device using the beam corresponding to the target used panel. In the data transmission method according to the embodiments of the disclosure, the first device reports its own capability level information about multiple panels to the second device, so that the second device can timely and accurately learn whether two or more panels of the first device can be activated and used at the same time, and the second device can better use multiple panels to transmit data with the first device, which may improve space diversity performance, reliability and robustness of the data transmission.

It should be noted that the first device may include devices such as smart phones, tablets, desktops, laptops, drones, or wearable devices (such as bracelets, and smart glasses), and the second device may include devices, such as base stations; or, the first device and the second device may be, for example, devices such as vehicle-mounted devices, roadside devices, or user handheld devices in Vehicle to Everything (V2x).

Alternatively, information such as the switching time between panels corresponding to different information on panel capability levels and the maximum power of each panel can be set in the second device, such as a base station, in advance.
