Abstract

The invention discloses a method and device for sending and receiving uplink control information, and belongs to the technical field of communication. In this method, a terminal device may receive a first DCI from a network device, determines that the uplink shared channel scheduled by the first DCI is only used for sending the UCI according to the received first DCI and then sends the first UCI to the network equipment through the uplink shared channel scheduled by the first DCI; that is to say, the network equipment indicates the terminal equipment through the DCI; therefore, the terminal equipment can determine whether the uplink shared channel scheduled by the DCI is only used for sending the UCI or not according to the indication of the DCI, a mode of determining that the uplink shared channel scheduled by the network equipment is only used for sending the uplink control information is provided, and the interaction performance between the network equipment and the terminal equipment is enhanced.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for sending and receiving uplink control information. Background technique [0002] In wireless communication, a terminal device may send uplink shared channel (uplink shared channel, UL-SCH) data to a network device, and may also send control information. [0003] Generally speaking, the terminal device can send only uplink control information to the network device through a physical uplink shared channel (PUSCH), or can also send data and uplink control information at the same time, and specifically whether to send only uplink control information or to send simultaneously Data and uplink control information cannot be determined by the terminal equipment at present. Contents of the invention [0004] The embodiments of the present application provide a method and device for sending and receiving uplink control information, which are ...
