UPLINK TRANSMISSION SUB-CARRIER BANDWIDTH INDICATION METHOD AND SELECTION METHOD, BASE STATION, AND USER EQUIPMENT

摘要

The present invention provides a method of indicating a subcarrier bandwidth for uplink transmission, executed by a base station, the method comprising: generating indication information, the indication information being used to indicate a subcarrier bandwidth for single-tone transmission in a first NB-PUSCH and/or a second NB-PUSCH after NB-PRACH transmission; and sending to a user equipment (UE) the generated indication information to indicate to the UE a subcarrier bandwidth for the single-tone transmission. Accordingly, the present invention further provides a method of selecting a subcarrier bandwidth for uplink transmission executed by a UE, and a base station and a UE respectively executing the above methods.
