Problems solved by technology

Due to the limitation of the device at the radio frequency end, when the received power changes drastically, the radio frequency amplifier AGC (Automatic Gain Control, automatic gain control) needs a certain period of time to adjust, and the signal during this adjustment period may not be received correctly

Embodiment Construction

[0052] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0053]In related technologies, in the Internet of Vehicles, due to the influence of long-distance transmission or fast movement of vehicles, channel fading may be severe, and signal power during reception may be greatly reduced. Due to the limitation of the device at the radio frequency end of the equipment, when the received power changes drastically, the radio frequency amplifier AGC (Automati...

Abstract

The invention relates to a method and device for transmitting control information and data. The method comprises the following steps: determining to-be-sent control information and time-frequency resources corresponding to user data; transmitting the control information and the user data on the time-frequency resource, wherein when a first time-frequency resource corresponding to the control information and a second time-frequency resource corresponding to the user data belong to the same time unit, part of the second time-frequency resource occupies a starting time domain symbol of the time unit; and/or, when the first time-frequency resource corresponding to the control information and the second time-frequency resource corresponding to the user data belong to different time units, the first time-frequency resource at least occupies half of the time domain symbol of the first time unit.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for transmitting control information and data. Background technique [0002] Among related technologies, Internet of Vehicles is a new generation of Internet. The Internet of Vehicles includes communication between on-board devices, on-board devices and roadside devices, and on-board devices and handheld devices. The communication may be direct communication, or may be relayed through a base station and a core network. Due to the limitation of the device at the radio frequency end, when the received power changes drastically, the radio frequency amplifier AGC (Automatic Gain Control, automatic gain control) needs a certain amount of time to adjust, and the signal during this adjustment time may not be received correctly. Contents of the invention [0003] Embodiments of the present invention provide a method and device for transmitting control infor...
