Fig. 4 is a schematic structural diagram of transmitting a plurality of uplink signals on a plurality of uplink channels of a special subframe in the embodiment of the present invention. As shown in fig. 4, at different time instances, SRS0 and SRS1, and uplink signal 3 may be transmitted on the special subframe. Here, the transmission length of data corresponding to SRS0 and SRS1 is 2192T_sThe transmission length of data corresponding to the uplink signal 3 is 4544T_sAnd then: the transmission time lengths of the initial transmission timings of SRS0 and SRS1 are both 2192T_sThe transmission time length of the initial transmission timing of the uplink signal 3 is 4544T_s。

According to the method for controlling the uplink signal transmission timing provided by the embodiment of the present invention, in the embodiment of the present invention, the starting time a3 of the initial transmission timing of the uplink signal 3 may be determined as the starting time of the target transmission timing, and the ending time B1 of the initial transmission timing of the SRS0 may be determined as the ending time of the target transmission timing, so that the transmission time duration of the target transmission timing is 4832T_s。

In order to ensure that the signals are transmitted on the 3 uplink channels according to the same transmission timing sequence, zero padding processing may be performed on the data of the 3 uplink signals, so that the data transmission lengths of the 3 uplink signals are matched with the transmission time length of the actual transmission timing sequence, that is, the actual transmission timing sequences of the 3 uplink signals are the same, and the transmission time lengths are the transmission time lengths of the target transmission timing sequence.

Fig. 5 is a schematic structural diagram of transmitting a plurality of uplink signals on a plurality of uplink channels of a normal subframe in an embodiment of the present invention. As shown in fig. 5, SRS, uplink signal 2 and uplink signal 3 may be transmitted on a regular subframe at different times. Wherein, the transmission length of data corresponding to SRS is 1symbol, the transmission length of data corresponding to uplink signal 2 is 13symbol, and the transmission length of data corresponding to uplink signal 3 is 14symbol, then: the transmission duration of the initial transmission timing of the SRS is 1symbol, the transmission duration of the initial transmission timing of the uplink signal 2 is 13symbol, and the transmission duration of the initial transmission timing of the uplink signal 3 is 14 symbol.

According to the method for controlling the transmission timing of the uplink signal provided by the embodiment of the present invention, in the embodiment of the present invention, the start time A3 or a2 of the initial transmission timing of the uplink signal 3 or the uplink signal 2 may be determined as the start time of the target transmission timing, and the end time B1 or B3 of the initial transmission timing of the SRS or the uplink signal 3 may be determined as the end time of the target transmission timing, so that the transmission time length of the target transmission timing is 14 symbol.

Specifically, in the embodiment of the present invention, the start time a1 of the initial SRS transmission sequence is later than the start time A3 or a2 of the target transmission sequence, and the difference 13symbol between the start time a1 of the initial SRS transmission sequence and the start time A3 or a2 of the target transmission sequence may be determined as the zero padding length of the data corresponding to the SRS, and the 13symbol may be padded at a position (as a shaded portion on the SRS channel in fig. 5) before the a 1.

The end time B2 of the initial transmission timing of the uplink signal 2 is earlier than the start time B1 or B3 of the target transmission timing, and the difference 1symbol between the end time B1 or B3 of the target transmission timing and the end time B2 of the initial transmission timing of the uplink signal 2 may be determined as the zero padding length of the data corresponding to the uplink signal 2, and 1symbol may be padded at a position (as a shaded portion on the PUCCH channel/PUSCH channel in fig. 4) after B2.

The initial transmission timing of the uplink signal 3 is the same as the determined target transmission timing, that is: the transmission time length of the initial transmission time sequence of the uplink signal 3 is the same as the transmission time length of the target transmission time sequence, and the start time and the end time of the initial transmission time sequence of the uplink signal 3 are also the same as the start time and the end time of the target transmission time sequence, respectively, so that zero padding processing does not need to be performed on data corresponding to the uplink signal 3.

Therefore, the method for controlling the transmission timing of uplink signals according to the embodiments of the present invention determines a target transmission timing according to a plurality of initial transmission timings of a plurality of uplink signals transmitted on a plurality of uplink channels with the same subframe number, and the zero padding position and the zero padding length of the data corresponding to the first uplink signal in the plurality of uplink signals are determined according to the first initial transmission time sequence in the plurality of initial transmission time sequences and the target transmission time sequence, performing zero padding processing on data corresponding to the first uplink signal, and further respectively transmitting the first uplink signal after the zero padding processing on the first uplink channel according to a target transmission timing sequence, therefore, the signals can be transmitted on different uplink channels according to the same transmission time sequence, so that the control on the transmission time sequence is simpler and is easy to realize when different uplink signals are transmitted on different uplink channels with the same subframe number.
