Description

TECHNICAL FIELD The present application relates to the field of communications and, more particularly, to a wireless communication method and devices. BACKGROUND In the current New Radio (NR) system, the flexibility of channel transmission is required to be high. For example, due to the limitation of the current transmission power of the terminal device, more flexible channel transmission is expected. Therefore, how to enhance the flexibility of channel transmission is an urgent problem to be solved. US 2013/250924 A1 relates to systems and methods for signaling and determining transmission time interval (TTI) bundling parameters. The method includes receiving signaling that indicates a TTI bundling configuration. The method also includes receiving signaling that indicates an uplink grant. The method further includes determining at least one TTI bundling parameter based on the TTI bundling configuration and the uplink grant. The method additionally includes transmitting a signal based on the at least one TTI bundling parameter. Further document 3GPP DRAFT; GUANGDONG OPPO MOBILE TELECOM: "Slot aggregation and configuration for NR long PUCCH", R1-1707713, (2017-05-14) provides further background for channel transmission. SUMMARY The invention is set out in the appended set of claims. The embodiments of the present application provide a wireless communication method and device, which can enhance the flexibility of channel transmission. Therefore, in the embodiments of the present application, the time unit can be dynamically selected to avoid performing channel transmission in a fixed time unit, and the present application can be applied to a scenario in which time domain resources occupied by the channel are different in size, thereby the flexibility of channel transmission can be enhanced. Further, when the transmission power of the terminal device is limited, a plurality of time units may be selected to transmit one channel.
