Title: TRANSMISSION TIMING METHOD AND APPARATUS
Abstract:
Disclosed are a transmission timing method and an apparatus. The transmission timing method comprises: based on a relationship between uplink transmission and downlink transmission, determining an uplink transmission time unit for transmitting an uplink signal; and receiving the uplink signal transmitted on the uplink transmission time unit that is determined. The relationship between the uplink transmission and the downlink transmission comprises: a ratio of duration of the uplink transmission time unit to duration of a downlink transmission time unit is m, or a ratio of a downlink sub-carrier interval to an uplink sub-carrier interval is m, wherein m is a natural number that is greater than 1. In embodiments of the present invention, uplink and downlink signal transmission timing can be determined based on the relationship between the uplink transmission and the downlink transmission, thus applying to a scenario where lengths of uplink and downlink sub-frames are different.
