Abstract

The invention relates to a method and device for receiving control information and transmitting control information, for flexibly adjusting reliability of uplink transmission. The method for configuring a control channel includes the steps: a network device sends indication information of an uplink control channel to a terminal device, wherein the indication information of the uplink control channel is used to indicate the following at least one transmission parameter: a time domain length parameter, a frequency domain length parameter, and a time domain repetition frequency parameter, a frequency domain repetition frequency parameter, and a transmit diversity mode parameter; and the network device receives the uplink control information from the terminal device by using the uplink controlchannel according to the indication information.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for receiving control information and sending control information. Background technique [0002] At present, when sending uplink information through the uplink control channel, the format of the uplink control channel is determined according to the content of the uplink information, and different PUCCH formats correspond to different reliability of uplink transmission. For example, the uplink control channel is a physical uplink control channel (PUCCH). If a 1-bit acknowledgment (ACK) / negative acknowledgment (NACK) is sent through the PUCCH, the PUCCH format 1a is used. If the channel quality is sent through the PUCCH Indication (channel quality indicator, CQI), PUCCH format 1 is used. [0003] However, even for the same uplink information, reliability requirements for uplink transmission may be different under different coverage scenario...
