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

Abstract

The present invention provides a method for controlling the transmission mode of an uplink control channel of a terminal, a transmission method and equipment, which belong to the technical field of wireless communication, wherein the method for controlling the transmission mode of a terminal's uplink control channel applied to a network side device includes: receiving an uplink signal sent by a terminal The uplink signaling includes the uplink control channel transmission mode supported by the terminal; the uplink channel of the terminal is measured to obtain the quality information of the uplink channel; according to the uplink signaling, the quality information and a preset quality threshold, determine the transmission mode of the uplink control channel of the terminal; send a first message to the terminal, and the first message is used to instruct the terminal to adjust the transmission mode currently used in the uplink control channel to the specified Describe the transmission mode determined by the network side device. Therefore, the transmission mode of the terminal on the uplink control channel can be made more reasonable, and an effective balance can be achieved among uplink coverage performance, terminal power consumption and processing complexity.

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
