摘要： An uplink transmission method using unlicensed spectrum is disclosed, comprising: performing a clear channel assessment (CCA) on at least one sub-channel corresponding to at least one frequency resource segment in an assigned frequency resource segment group, and thus determining whether the at least one sub-channel is clear, wherein the frequency resource segment group may be generated by segmenting and grouping the unlicensed spectrum; and when the at least one sub-channel corresponding to the at least one frequency resource segment is clear, using at least one clear sub-channel for uplink transmission. Resource assignment methods, user equipment, and base stations using unlicensed spectrum are also disclosed. The present disclosure can reduce the blocking probability among intra-cell and inter-cell user equipment (UE) during Licensed- Assisted Access (LAA) uplink transmission, and thus can improve the channel access probability.

摘要： 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.
