Abstract: This application discloses example methods and apparatuses for information transmission. One example method includes receiving, by a terminal device, downlink control information that includes first information used to indicate a symbol that carries uplink control information. The terminal device can then determine, based on the first information, the symbol that carries the uplink control information, and can map the uplink control information to the symbol that carries the uplink control information. The terminal device then sends the uplink control information to a network device.

Abstract: A timing method for time division duplex communication, an uplink/downlink data scheduling method, a base station, and user equipment are provided. By determining whether grouping needs to be performed on uplink/downlink short transmission time intervals, it is determined, for different grouping requirements, whether addition of indication information to control signaling is required to indicate to user equipment an uplink short transmission time interval sequence number in an uplink short transmission time interval group for uplink data transmission or feedback to downlink data scheduling. Alternatively, addition of indication information to control signaling is not required, and uplink data transmission or feedback to downlink data scheduling is performed in an uplink short transmission time interval determined according to a default rule.
