摘要： A method and apparatus for pulse interference suppression, and a computer readable storage medium in a communication system are provided in the embodiments of the present invention. The method includes: judging a location where pulse interference occurs according to a power of a signal; and performing suppression processing on a data segment interfered by a pulse in the location. After judging that the pulse interference exists in the location, a receiver in the communication system discards the data segment interfered by the pulse in the location, and feeds back an indication that the data are not received.

摘要： A method and base station for coordinated multi point data transmission are disclosed. The method includes: a base station receiving a per-cell CQI value reported by a UE; looking up an SINR-CQI mapping table according to the per-cell CQI value, and acquiring a subband/broadband SINR value; performing CQI recalculation according to the subband/broadband SINR value, and acquiring a recalculated subband/broadband CQI value; and selecting modulation and coding according to the recalculated subband/broadband CQI value to schedule data transmission. With the method and base station of the embodiments of the present document, in a CoMP system, in a joint transmission scenario, the accuracy of the CQI value used by the BS for scheduling is improved, and the oscillation during an AMC process is reduced.
