Abstract: For LTE cellular data and Wi-Fi P2P technology coexistence scenario, a user equipment can generate in-device coexistence (IDC) indication message to the base station for DRX-based IDC solution. LTE data scheduling is described by a set of DRX parameters, while Wi-Fi P2P data scheduling is described by Opportunistic Power Saving (OppoPS) and Notification of Absence (NoA) parameters. When generating the IDC indication message for Wi-Fi P2P group client (GC), the DRX parameters must be selected carefully to maximize efficiency. Even though Wi-Fi shares less time, with proper time alignment, its coexistence performance could be better. For Wi-Fi P2P group owner (GO) with IDC TDM scheduling constraints, OppoPS and NoA should be aligned with DRX parameters to achieve best performance.

Abstract translation: 对于LTE蜂窝数据和Wi-Fi P2P技术共存场景，用户设备可以向用于基于DRX的IDC解决方案的基站生成设备内共存（IDC）指示消息。 通过一组DRX参数描述LTE数据调度，而通过机会节能（OppoPS）和缺席通知（NoA）参数来描述Wi-Fi P2P数据调度。 当生成用于Wi-Fi P2P组客户端（GC）的IDC指示消息时，必须仔细选择DRX参数以最大化效率。 即使Wi-Fi拥有更少的时间，随着时间的推移，其共存性能可能会更好。 对于具有IDC TDM调度约束的Wi-Fi P2P组所有者（GO），OppoPS和NoA应与DRX参数对齐以实现最佳性能。
