阅读说明：本技术 一种用于载波聚合的方法、装置及系统 (Method, device and system for carrier aggregation ) 是由 张茜 黎超 邓猛 柴洪林 于 2018-08-10 设计创作，主要内容包括：本申请实施例公开了一种用于载波聚合的方法、装置及系统。该用于载波聚合的方法包括：终端接收来自无线网络设备的对应于第一成员载波的第一消息,以及对应于第二成员载波的第二消息,所述第一消息包括所述第一成员载波的载波偏置信息,子载波间隔信息以及载波带宽信息,其中,所述第一成员载波的载波带宽信息用于指示所述第一成员载波的最大传输带宽配置；接收对应于所述第二成员载波的第二消息,所述第二消息包括所述第二成员载波的载波偏置信息,子载波间隔信息以及载波带宽信息,其中,所述第二成员载波的载波带宽信息用于指示所述第二成员载波的最大传输带宽配置；根据所述第一消息和所述第二消息确定所述第一成员载波和所述第二成员载波之间的标称信道间距。采用本申请实施例提供的方案,能够有效地提升确定标称信道间距的准确性,进而提升用于载波聚合的方案的性能或降低用于载波聚合的方案的成本。(The embodiment of the application discloses a method, a device and a system for carrier aggregation. The method for carrier aggregation includes: a terminal receives a first message corresponding to a first member carrier and a second message corresponding to a second member carrier from a wireless network device, wherein the first message comprises carrier offset information, subcarrier spacing information and carrier bandwidth information of the first member carrier, and the carrier bandwidth information of the first member carrier is used for indicating the maximum transmission bandwidth configuration of the first member carrier; receiving a second message corresponding to the second component carrier, the second message including carrier offset information, subcarrier spacing information, and carrier bandwidth information of the second component carrier, wherein the carrier bandwidth information of the second component carrier is used to indicate a maximum transmission bandwidth configuration of the second component carrier; determining a nominal channel spacing between the first component carrier and the second component carrier based on the first message and the second message. By adopting the scheme provided by the embodiment of the application, the accuracy of determining the nominal channel spacing can be effectively improved, and the performance of the scheme for carrier aggregation is improved or the cost of the scheme for carrier aggregation is reduced.)
