Methods and apparatuses are provided for calibrating delay between signal paths. A first terminal determines a delay offset value based on a first delay value of a first channel between the first terminal and an entity, and a second delay value of a second channel between the first terminal and the entity. The delay offset value is transmitted from the first terminal to a second terminal. The second terminal uses the delay offset value to determine a third delay value of a third channel between the second terminal and the entity based on a fourth delay value of a fourth channel between the second terminal and the entity, wherein the fourth delay value is determined by the second terminal. 提供了种用于校准信号路径之间的延迟的设备和方法，其中，第终端基于第终端和实体之间的第信道的第延迟值以及第终端和所述实体之间的第二信道的第二延迟值来确定延迟偏移值。延迟偏移值被从第终端发送到第二终端。第二终端使用延迟偏移值来基于第二终端和所述实体之间的第四信道的第四延迟值确定第二终端和所述实体之间的第三信道的第三延迟值，其中，第四延迟值是由第二终端确定。
