Abstract

Embodiments of the present invention provide a method and device for transmitting signals. The method includes: the first device determines the first frequency corresponding to the first subcarrier used to map the first signal in the first period according to the first subcarrier-frequency mapping method, and sends the first signal on the first frequency; The first device determines the second frequency corresponding to the second subcarrier used to map the second signal in the second period according to the second subcarrier-frequency mapping method, and sends the second signal on the second frequency; wherein the first The subcarrier-frequency mapping method is different from the second subcarrier-frequency mapping method, and the first frequency and the second frequency belong to the same frequency band. The embodiment of the present invention can use the same subcarrier-frequency mapping method to transmit signals during uplink and downlink transmission within a period of time, which improves the transmission performance of the system and improves the use efficiency of the frequency band.

Description

technical field [0001] Embodiments of the present invention relate to a communication system, and in particular, to a method and device for transmitting signals. Background technique [0002] The user equipment usually transmits wireless signals with the network equipment in a wireless manner. The transmission of wireless signals from the user equipment to the network equipment is called uplink transmission, and the transmission of wireless signals from the network equipment to the user equipment is called downlink transmission. [0003] Usually, the uplink transmission and the downlink transmission are designed separately, so as to ensure that the uplink and downlink respectively meet the technical requirements. For example, in the current LTE system, the uplink transmission adopts the Single-carrier Frequency-Division Multiple Access (SC-FDMA) method, and the downlink transmission adopts the Orthogonal Frequency Division Multiple Access (OFDMA) method. . [0004] After t...
