Title: UPLINK TRANSMISSION METHOD, BASE STATION, AND UE
Abstract:
The present invention relates to the field of communications, and provides an uplink transmission method, base station, and UE, used to at least solve, in a scenario of a base station instructing, in subframe #n, a UE unit to send a padding signal in subframe #n+4, a problem in which a lost UL grant in subframe #n influences uplink transmission in subframe #n+5, and solve, in a scenario in which absence of PUSCH transmission in subframe #n+4 causes that a UL grant is not sent in subframe #n, a problem in which no UL grant being sent in subframe #n influences uplink transmission in subframe #n+5. The method comprises: a base station sends, in a first subframe, to UE first downlink transmission information used to instruct the UE to send, in a second subframe, first uplink data, and to instruct the UE to send, in a third subframe, an uplink sounding signal. The second subframe and the third subframe are later than the first subframe in time, the second subframe and the third subframe are contiguous in time, and the second subframe is later than the third subframe.
