Uplink information transmission method, base station, and user equipment

An uplink transmission method, comprising:

• performing, by user equipment (UE), a first uplink transmission in a subframe within a first subframe set using a first frequency resource within a first narrowband, the first subframe set being located in a first radio frame;
• and
• performing, by the UE, a second uplink transmission in a subframe within a second subframe set using a second frequency resource within a second narrowband, the second narrowband being different from the firm narrowband, the second subframe set being located in a second radio frame, wherein the first uplink transmission and the second uplink transmission are adjacent uplink transmissions in time from the UE, and wherein no reserved interval subframe is present between the first subframe set and the second subframe set.

An uplink transmission receiving method, comprising:

• receiving, by a base station, a first uplink transmission in a subframe within a first subframe set using a first frequency resource within a first narrowband, the first subframe set being located in a first radio frame;
• and
• receiving, by the base station, a second uplink transmission in a subframe within a second subframe set using a second frequency resource within a second narrowband, the second narrowband being different from the first narrowband, the second subframe set being located in a second radio frame, wherein the first uplink transmission and the second uplink transmission are adjacent uplink transmissions in time from a same transmitter, and wherein no reserved interval subframe is present between the first subframe set and the second subframe set.
