阅读说明：本技术 主蜂窝小区群和副蜂窝小区群共存 (Primary and secondary cell groups co-exist ) 是由 P·P·L·昂 晓风·王 J·蒙托约 P·盖尔 陈万士 H·李 J·B·索里亚加 于 2019-03-22 设计创作，主要内容包括：描述了用于无线通信的方法、系统和设备。无线通信网络可以为双连通性中的蜂窝小区群设置优先级。较高优先级蜂窝小区群(例如主蜂窝小区群MCG或副蜂窝小区群SCG)可以保留时隙,并且例如通过回程连接向较低优先级蜂窝小区群(例如互补即SCG或MCG)指示所保留时隙。高优先级蜂窝小区群还可指示附加的、非所保留时隙,较低优先级蜂窝小区群可以将其保留或用于调度。蜂窝小区群之一可以在双连通性中向用户装备(UE)传送时隙格式指示(SFI)以指示时隙保留。在一些情形中,混合自动重复请求(HARQ)定时参数可基于所保留时隙的数目。在一些情形中,功率控制可基于UE是否能够同时进行上行链路和下行链路传输来改变。(Methods, systems, and devices for wireless communication are described. The wireless communication network may prioritize cell groups in dual connectivity. A higher priority cell group (e.g., primary cell group MCG or secondary cell group SCG) may reserve time slots and indicate the reserved time slots to a lower priority cell group (e.g., complementary or SCG or MCG), e.g., over a backhaul connection. The high priority cell group may also indicate additional, unreserved time slots that a lower priority cell group may reserve or use for scheduling. One of the cell groups may transmit a Slot Format Indication (SFI) to a User Equipment (UE) in dual connectivity to indicate a slot reservation. In some cases, a hybrid automatic repeat request (HARQ) timing parameter may be based on the number of reserved slots. In some cases, power control may change based on whether the UE is capable of simultaneous uplink and downlink transmissions.)
