Method and device for sending uplink control channel

Abstract

The invention provides a method and a device for sending data, and a terminal device, the method comprises the following steps of: according to first information, the terminal device determining transmit power, wherein the first information comprises at least one of the following information: the information of the channel coding type of the uplink control information in the uplink control channel, length information of check code bits in the uplink control information, information of the number of resources occupied by uplink reference signals in the uplink control channel, information aboutwhether the uplink control channel adopts a frequency hopping mode or not and a transmission format of the uplink control channel; and the terminal device sending the uplink control channel accordingto the sending power, so that the reliability and the accuracy of communication can be improved.

Description

technical field [0001] The present application relates to the communication field, and, more specifically, to a method and device for sending an uplink control channel, and a terminal device. Background technique [0002] In order to ensure the reliability and accuracy of communication, the sending power can be compensated during the sending process of the uplink control channel. For example, in a Long Term Evolution (Long Term Evolution, LTE) system, therefore, the compensation power can be determined based on the following formula 1: [0003] Δ TF =10log 10 (2 1.25·T -1) Formula 1 [0004] Among them, Δ TF Represents the compensation power, and T represents the number of unit resource element bits (Bit Pre Resource Element, BPRE) corresponding to the uplink control information in the uplink control channel. Generally, the number of unit resource element bits is defined as including the check bit (Cyclic Redundancy Check) bit The ratio between the number of uplink con...

Problems solved by technology

[0005] However, in this technology, only the BPRE corresponding to the uplink control information is considered in the process of determining the compensation power. With the development of communication technology, the requirements for reliability and accuracy are getting higher and higher. The transmission parameters are also more flexible, and different transmission parameters have different requirements for the transmission power compensation of the uplink control channel. Therefore, the above-mentioned fixed power compensation technology based on a single parameter can no longer meet the reliability and accuracy requirements of communication.
