<p>The embodiments of the present invention relate to the technical field of wireless communications, in particular to a method, system and device for transmitting and receiving uplink information, which are used for solving the problem that uplink channels/signals in neighboring subframes collide in some Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbols due to unaligned uplink transmission time for carriers in different Time Advance group (TA group).The method provided by the embodiments comprises: the use equipment with a plurality of uplink TA groups determines K SC-FDMA symbols in the current uplink subframe in the uplink carriers reserved for transmitting no uplink information, wherein K is a non-minus integer (501), and maps the uplink information to be transmitted on SC-FDMA symbols in the current uplink subframe in the uplink carrier, for transmitting uplink information, except for the reserved K SC-FDMA symbols, in order to transmit the uplink information (502). By the embodiments of the invention, the problem that the uplink channels/signals in the neighboring subframes collide in some SC-FDMA symbols due to unaligned uplink transmission time for carriers in different TA groups can be solved.</p> |
