摘要:
The present invention relates to the wireless network communication field, and discloses a method for handover between multi-carrier cells to avoid repeated handover decisions caused by delay of the triggering event. The method includes: the source cell receives a measurement report triggered by an event reported by a served User Equipment (UE); and the source cell executs a handover decision according to measurement reports triggered by multiple events after receiving the measurement reports triggered by the multiple events within an estimated interval, and hands over the UE to the corresponding carrier of the corresponding target cell. With the present invention, the resources of the source cell and the target cell may be saved, and the handover efficiency may be improved.

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.

A method for controlling uplink power of an LTE system, a base station, and a mobile terminal are disclosed according to the embodiments of the present invention. The method includes: obtaining uplink transmit power of each carrier; sending first notification signaling to a base station if a difference between the obtained uplink transmit power of each carrier exceeds a specific threshold; and sending second notification signaling to the base station if a sum of the obtained uplink transmit power of each carrier exceeds a preset threshold. Thresholds are determined according to network conditions, and uplink power of a carrier is adjusted in a balanced way, a bit error rate is reduced and a case that a low-performance carrier is forced to be interrupted is prevented.

A method, a device and a system for a relay to establish a connection with a base station are disclosed. Interface information sent from a serving base station is received. Resource information is obtained from the interface information. The resource information is used to indicate wireless resources used when the relay communications with a non-serving base station. A wireless connection is established with the non-serving base station in the wireless resources indicated by the resource information.

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:
Embodiments of the present invention provide a method and a user equipment for cell selection of a heterogeneous network. The UE selects, a cell with a highest signal measurement value in a carrier frequency synchronizes to the cell, and receives broadcast information of the cell. If the cell is a macro cell, the broadcast information carries an extended indicator bit and the extended indicator bit is used to identify whether a low-power cell exists in the coverage of the macro cell. If the extended indicator bit identifies that the low-power cell exists in the coverage of the macro cell, the low-power cell in the macro cell is searched for, and if a low-power cell in the macro cell satisfies an S rule, the UE selects the lower-power cell as a serving cell and camps.
