摘要： Embodiments of this application provide a method and an apparatus for transmitting channel state information (CSI). The CSI is a part of uplink control information (UCI) and it includes a first quantity of bits. The method includes: determining a threshold code rate according to a modulation and coding scheme (MCS) index when the CSI is to be transmitted on a physical uplink shared channel (PUSCH) without uplink data; determining a second quantity of bits according to the threshold code rate and the first quantity of bits, where the second quantity of bits is less than or equal to the first quantity of bits; and transmitting the second quantity of bits of the CSI on the PUSCH.

摘要： Example uplink control information transmission methods and apparatus are provided. One example method includes receiving first indication information, where the first indication information includes a parameter β and a parameter α. First information is determined based on the first indication information. A quantity of resources for sending uplink control information (UCI) is determined based on first information. The first information includes scheduling information, a ratio of a quantity of bits of the UCI to a quantity of bits of data, a first preset parameter, the parameter β, a quantity of available resources of a physical uplink shared channel (PUSCH), and the parameter α. The parameter β is an offset of the UCI. The parameter α is configured by higher layer signaling and the parameter α is less than 1. The UCI is sent to a network device based on the determined quantity of resources for sending the UCI.

摘要： This application discloses methods an apparatuses for sending and receiving uplink control information in the field of communications technology. In some implementations, a terminal device may receive first downlink control information (DCI) from a network device; determine, based on the received first DCI, that an uplink shared channel scheduled by using the first DCI is used to send only uplink control information (UCI); and send first UCI to the network device through the uplink shared channel scheduled by using the first DCI. In other words, the network device indicates to the terminal device by using DCI so that the terminal device can determine, based on an indication of the network device, whether the uplink shared channel scheduled by using the DCI is used to send only the UCI.
