Patent ID: 10333610

Abstract:
Disclosed in embodiments of the present invention are an MCS index determination method and base station equipment. The method comprises: calculating, by a base station equipment and according to a first SINR obtained by measuring an SRS signal at time k0, a second SINR of a PUSCH signal; determining, by the base station equipment and according to the second SINR, a first MCS index; and calculating, by the base station equipment and according to the first MCS index and data volume actually required to be transmitted by a user, an actually scheduled PRB amount, and a second MCS index actually used. In an embodiment of the present invention, an MCS index of PUSCH matches an actual SINR of a PUSCH channel to effectively ensure receiving performance of the PUSCH, thereby increasing an uplink transmission efficiency of an LTE system, and particularly increasing an uplink transmission efficiency of a user near a cell edge, so as to ensure PUSCH transmission performance of a user near the cell edge or having a large path loss, and facilitate an increase in an uplink service rate of the edge user.
