摘要： The present invention discloses a method and an apparatus for notification of emitted energy. The method includes: performing an emitted energy decrease on resource elements in a current cell that have a same time-frequency location as part or all of resource elements where a reference signal of a neighboring cell is located; obtaining an emitted energy parameter of an energy non-decreased resource element (NRE) in the current cell according to a decreased amount of emitted energy of an emitted energy decreased resource element (DRE); and notifying the emitted energy parameter of the NRE to a user equipment (UE). According to embodiments of the present invention, the waste of emitted energy may be avoided, the emitted energy of part of REs is increased, and further, the signal to interference plus noise ratio (SINR) and throughput of service data may be increased.

摘要： A method, a network device, and a system for determining resource mapping in CoMP transmission are disclosed. The method includes: the cooperative cells that perform CoMP transmission for a UE negotiate a mapping rule used by the cooperative cells when the status of the CoMP transmission of the UE changes, where the mapping rule includes the number of and position of OFDM symbols allocated to a PDCCH domain and/or a data channel domain; and the negotiated mapping rule is notified to the UE. In this embodiment, before the downlink signals are transmitted, the mapping rule used by each cooperative cell for CoMP transmission is negotiated between the cooperative cells, and therefore, the UE can accurately receive the signal sent by multiple cooperative cells and the performance of CoMP transmission in the system is improved.
