Title
(EN) Uplink power sharing in dual connectivity
(ZH) 双连接性中的上行链路功率共享
Abstract
(EN) Systems and methods enabling uplink power sharing for dual connectivity are disclosed. Embodiments are described herein in which a maximum Uplink (UL) power on each link is configured statically, semi-statically, or dynamically. In general, regardless of the embodiment, uplink power for uplink transmissions from a wireless device on two simultaneous links is controlled such that the total uplink power does not exceeds a maximum UL transmission power level while, in some embodiments, taking into account priorities of the two links and/or priorities of various uplink channels transmitted by the wireless device on the two links. Notably, while the embodiments described herein focus on dual connectivity, the embodiments described herein can easily be extended to any number of two or more simultaneous links.
(ZH) 公开实现对于双连接性的上行链路功率共享的系统和方法。本文描述实施例,其中静态、半静态或动态地配置各链路上的最大上行链路(UL)功率。一般来说,不管本实施例,在两个同时链路上来自无线装置的上行链路传输的上行链路功率被控制使得总上行链路功率没有超过最大UL传输功率级,而在一些实施例中,考虑两个链路的优先级和/或无线装置在两个链路上传送的各种上行链路信道的优先级。值得注意,虽然本文所描述的实施例聚焦于双连接性,但是本文所描述的实施例能够易于扩展到任何数量的两个或更多同时链路。
