Abstract
Official abstract text for this publication.
Provided is a method for transmitting a reference signal in a time division duplex (TDD)-based wireless communication system. A base station transmits a synchronization signal in a subframe including N resource blocks in a frequency domain, and K (K>1) orthogonal frequency division multiplexing (OFDM) symbols in a time domain. The base station transmits a reference signal generated on the basis of a terminal identifier in the subframe. The subframe includes a downlink pilot time slot (DwPTS), a guard period (GP), and an uplink pilot time slot (UpPTS). The DwPTS includes six OFDM symbols. The UpPTS includes two OFDM symbols. The reference signal is transmitted in the first OFDM symbol or the sixth OFDM symbol in the subframe.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for transmitting reference signals in a wireless communication system based on Time Division Duplex (TDD), the method comprising: transmitting, by a transmitter, a synchronization signal in a subframe, the subframe comprising K (K>1) Orthogonal Frequency Division Multiplexing (OFDM) symbols in a time domain and N resource blocks in a frequency domain, where N is an integer; and transmitting, by the transmitter, a reference signal in the subframe,…
