Method for controlling transmitting mode of uplink control channel of terminal, transmitting method and equipment

Abstract

The invention provides a method for controlling a transmitting mode of an uplink control channel of a terminal, a transmitting method and equipment, and belongs to the technical field of wireless communication. The method for controlling the uplink control channel transmission mode of the terminal applied to the network side equipment comprises the steps: receiving uplink signaling which is transmitted by the terminal and comprises an uplink control channel transmission mode supported by the terminal; measuring an uplink channel of the terminal to obtain quality information of the uplink channel; determining the transmitting mode of the uplink control channel of the terminal according to the uplink signaling, the quality information and a preset quality threshold; and sending a first message to the terminal, wherein the first message is used for indicating the terminal to adjust a transmitting mode currently adopted in the uplink control channel to the transmitting mode determined by the network side equipment. Therefore, the transmitting mode of the terminal in the uplink control channel is more reasonable, and the uplink coverage performance, the terminal power consumption and the processing complexity are effectively balanced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for controlling the transmission mode of an uplink control channel of a terminal, a transmission method and a device. Background technique [0002] Since the mainstream frequency band used by 5G is higher than that of 4G, there will be a problem of insufficient uplink coverage. Taking 5G using the 3.5GHz frequency band and 4G using the 2.6GHz frequency band as examples, the simulation results show that when the terminal uses a single antenna to transmit and the transmission power is 23dBm, the uplink coverage of the 3.5GHz frequency band will be about 5dB lower than that of the 2.6GHz frequency band. If the terminal adopts dual-antenna transmission and the total transmission power is 26dBm, it can effectively increase the uplink coverage of the 3.5GHz frequency band by 3-5dB, which is reflected in the 3dB gain of increasing the transmission power a...

Problems solved by technology

[0004] However, although the 5G terminal adopts the uplink dual-antenna transmission scheme, which can increase the uplink transmission rate and enhance the uplink coverage, the simultaneous operation of two power amplifiers (Power Amplifier, PA) will also lead to higher power consumption of the terminal. The problem

Especially in the center of the cell, when the terminal is mainly used for downlink data transmission, and the uplink is mainly used for control signaling transmission, the dual-antenna transmission scheme of the uplink control channel will bring unnecessary power consumption
