Abstract: Embodiments of the present invention provide a method and apparatus for sending and receiving a signal, and relate to the field of wireless communication, where a quantity of pilots does not increase with increasing paired data streams of an MU-MIMO system, and overheads of the pilots are fixed. The method includes: determining, by a transmitter, a transmitting precoding vector of a primary pilot signal of a first receiver and an estimated receiving filtering vector; determining a transmitting precoding vector of a secondary pilot signal of the first receiver; determining a to-be-sent primary pilot signal, to-be-sent user data of the first receiver, and a to-be-sent secondary pilot signal; and sending the first receiver the to-be-sent primary pilot signal, the to-be-sent user data of the first receiver, and the to-be-sent secondary pilot signal.

Abstract: A time division duplex (TDD) transmission time interval (TTI) communicating transmissions in a first direction may include one or more regions for communicating in a second direction, where the first direction is a transmit direction and the second direction is a receive direction, or vice versa. A radio frame may include TDD TTIs with such regions and/or TDD TTIs without such regions for wireless communication, and these TDD TTIs may further be configured in accordance with different frame structure configurations, such as different TTI lengths, subcarrier spacings or symbol durations.
