The present disclosure discloses a network resource allocation method and apparatus, and a base station, pertaining to the wireless communications field. The method includes: receiving, by an evolved NodeB (eNB), a channel quality indicator (CQI) sent by a terminal; obtaining, by the eNB, a first modulation and coding scheme (MCS) of the terminal according to the CQI; allocating, by the eNB according to an amount of to-be-transmitted data and the first MCS, to the terminal a first resource block (RB) set required for transmitting the to-be-transmitted data; and adjusting, by the eNB, the first RB set according to a service type of the to-be-transmitted data and the first MCS.
