Abstract: The present disclosure provides a handover method. The method may include at least one of following measurement events to be triggered. The measurement events may include: an event D1, a measurement value of a neighbor cell is better than a measurement value of a best cell in a candidate target cell list; an event D2, the measurement value of the neighbor cell is better than the measurement value of the best cell in the candidate target cell list, and a measurement value of a serving cell is worse than a third threshold; an event D3, a number of the candidate cell which has a measurement value worse than a fourth threshold is greater than a fifth threshold; and an event A1, a measurement value of the serving cell is better than a sixth threshold. The present disclosure provides a communication handover apparatus and a readable storage medium.

Abstract: The present disclosure provides a dual connectivity-based handover method. The method includes: assisting a user equipment, by a source base station, to enter a dual connectivity state, the user equipment in the dual connectivity state simultaneously connecting to the source base station and a target base station, with the source base station serving as a master node and the target base station serving as a secondary node; and assisting the user equipment, by the source base station, to switch from the dual connectivity state to a single connectivity state of only connecting to the target base station, which may be initiated when a communication fault occurs between the source base station and the user equipment. The present disclosure also provides a dual connectivity-based handover apparatus. With this method, the present disclosure may reduce the possibility of Ping-Pong effect, the complexity of the handover process and the signaling overhead.

Abstract: A resource selection method and apparatus for device-to-device/vehicle-to-everything communication supporting carrier aggregation are disclosed. The resource selection method includes: initializing at least two resource pools, wherein each resource pool corresponds to one carrier; excluding an expected-busy resource from each resource pool associated with a resource of which channel signal strength is greater than a comparison threshold during a sensing period; determining whether remaining resources of a candidate resource pool meet a criterion for stopping resource exclusion, wherein the candidate resource pool comprises a portion of or all the resource pools, and the criterion comprises that a criteria parameter of the candidate resource pool is greater than or equal to a preset threshold of the criteria parameter; selecting a resource subset from the remaining resources of the candidate resource pool when the criterion is met, and otherwise incrementing the comparison threshold.

Abstract: Methods for multi-user MIMO co-scheduling with interference measurement are disclosed. A method includes: transmitting a first RS to a UE; receiving a first CSI feedback from the UE as the UE measures the first RS; transmitting initial co-scheduling information and a second RS to the UE, the initial co-scheduling comprising an identifier of at least one co-scheduled object that is to use the same time-frequency resource as the UE by Spatial Multiplexing (SM) in the data transmission, the initial co-scheduling information being derived based on the first CSI; receiving a second CSI feedback from the UE as the UE measures the second RS at least based on the initial co-scheduling information, the second CSI comprising an indication of an interference level from at least one co-scheduled object; and adjusting the initial co-scheduling information according to the second CSI to obtain refined co-scheduling information. The method can be applied to Full-Dimension MIMO. Associated base stations and UEs are also disclosed.
