阅读说明：本技术 一种多跳网络的跳频方法及装置 (Frequency hopping method and device of multi-hop network ) 是由 王宇晨 吴毅凌 于 2019-04-01 设计创作，主要内容包括：本申请提供了一种多跳网络的跳频方法及装置。该方法可应用于各类通信系统,例如：V2X、LTE-V、V2V、MTC、IoT、LTE-M、M2M等,其中,第一装置通过基站的第一消息获取基站指示的跳频资源；然后,第一装置根据跳频资源包含的跳频载波集合和可用跳频载波集合生成跳频图案；最后,第一装置将跳频资源发送给第二装置,以指示第二装置获得相同的跳频图案,使第一装置和第二装置能够使用相同的跳频图案进行跳频传输。由于基站为第一装置指示的跳频载波集合和可用跳频载波集合的频点范围和数量可以不受子小区的载波资源的限制,因此,本申请的方法可以使第一装置的子小区使用更多的载波频点进行跳频,从而获得更大的跳频范围,提高子小区对抗窄带干扰的能力。(The application provides a frequency hopping method and a frequency hopping device of a multi-hop network. The method can be applied to various communication systems, such as: V2X, LTE-V, V2V, MTC, IoT, LTE-M, M2M and the like, wherein the first device acquires the frequency hopping resource indicated by the base station through a first message of the base station; then, the first device generates a frequency hopping pattern according to a frequency hopping carrier set and an available frequency hopping carrier set contained in the frequency hopping resource; finally, the first device sends the frequency hopping resource to the second device to instruct the second device to obtain the same frequency hopping pattern, so that the first device and the second device can use the same frequency hopping pattern for frequency hopping transmission. Because the frequency point ranges and the number of the frequency hopping carrier set and the available frequency hopping carrier set indicated by the base station for the first device can not be limited by the carrier resources of the sub-cells, the method can enable the sub-cells of the first device to use more carrier frequency points for frequency hopping, thereby obtaining a larger frequency hopping range and improving the capability of the sub-cells to resist the narrow-band interference.)
