Embodiment Construction

[0061] 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.

[0062] In the related art, in the LTE (Long Term Evolution) Internet of Vehicles, the control channel and the traffic channel are frequency-division multiplexed, so the control channel and the traffic channel determine their respective automatic gain factors. However, in the 5G (fifth generation mobile communication system) NR (new air interface) Internet of Vehicles, the control channel and the...

Abstract

The invention relates to a method and device for receiving analog signals. The method includes: determining a first automatic gain factor of a control channel in a time slot; receiving a first analog signal of a control channel sent by the same user equipment in a time slot according to the first automatic gain factor; determining a first automatic gain factor in a time slot The second automatic gain factor of the traffic channel; wherein, the control channel and the traffic channel are time-division multiplexed; according to the second automatic gain factor, receiving the second analog signal of the traffic channel sent by the same user equipment in a time slot .

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for receiving analog signals. Background technique [0002] Among related technologies, the Internet of Vehicles is a new type 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 of the equipment, when the received power changes drastically, the radio frequency amplifier AGC (Automatic Gain Control, automatic gain control) needs to be adjusted. In the NR (new air interface) V2X (between vehicle equipment and any equipment) system, the multiplexing mode of the control channel and the traffic channel can be TDM (time division multiplexing). For the TDM multiplexing mode...
