Referring to FIG. 27 and FIG. 33, FIG. 34 shows an uplink information sending apparatus 3400 according to an embodiment of the present invention. The uplink information sending apparatus 3400 includes: a receiving module 3401, configured to receive downlink data, and located in a wireless transceiver Y02; an obtaining module 3402, configured to obtain an effective transmission time of first uplink information, and located in a baseband processor Y01; and a sending module 3403, configured to send the uplink information according to the effective transmission time, and located in the wireless transceiver Y02. For a specific function of each module in the apparatus corresponding to FIG. 34, refer to descriptions in the foregoing method embodiments.
In the embodiments corresponding to FIG. 33 and FIG. 34 in the present embodiments, user equipment may obtain, from a mapping of a control parameter of second uplink information or a mapping of a randomly accessed PRACH resource, an effective transmission time for sending first uplink information, and a base station does no need to use additional signaling to perform configuration. This simplifies a signaling process between the base station and the user equipment and implementation of the user equipment.
