摘要： The present invention relates to the radio communication field and discloses a method, an apparatus, and a system for handover between multi-carrier cells, so that a user equipment (UE) can be handed over to carriers of different cells on multiple target evolved NodeBs (eNBs). The handover method includes: after performing handover request acknowledge, receiving serial numbers (SNs) of data to be transferred and identifier information of target eNBs of other carriers to which the UE is handed over sent by a source eNB; and transferring scheduling information to the target eNBs of other carriers to which the UE is handed over.

摘要： A method, relevant equipment and system for determining a User Equipment (UE) or UEs affecting a neighboring cell are disclosed. The method for determining UE or UEs affecting a neighboring cell includes: receiving load information sent by a neighboring cell, where the load information indicates an interfered Physical Resource Block (PRB) of the neighboring cell; determining a UE or UEs that occupy, when scheduling is performed, the interfered PRB; determining UEs located in an Inter-Cell Interference Coordination (ICIC) measurement area corresponding to the neighboring cell; and obtaining an intersection of the UE or UEs that occupy, when scheduling is performed, the interfered PRB and the UE or UEs located in the ICIC measurement area corresponding to the neighboring cell. The technical solution under the present invention enables accurate determining of the UE or UEs that affect the neighboring cell.

摘要： The present invention provides a method for obtaining an uplink transmit power control parameter, where the method is applicable to a radio communication system using a CoMP transmission technology and includes: obtaining, by an base station, a downlink path loss of a serving cell serving for a UE and a sum of a each difference between a downlink path loss of each coordinated cell serving for the UE and the downlink path loss of the serving cell; obtaining, by the base station, a downlink path loss of the UE in a coordinated multi-point transmission environment and a transmit power control command of the UE in the coordinated multi-point transmission environment according to the downlink path loss of the serving cell and the sum of differences between downlink path losses. Thereby, the reduction of cell throughput and waste of UE power consumption is avoided.
