Embodiment Construction

[0031]Reference will now be made to some embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0032] figure 1 is a user equipment with a multi-radio transceiver in a wireless communication system 100 according to an aspect of the present invention. The wireless communication system 100 includes a user equipment UE101 , a serving base station (such as an evolved node) eNB102 and a Wi-Fi device Wi-Fi 103 . The wireless communication system 100 provides various network access services for the UE 101 through different radio access technologies. For example, eNB 102 provides cellular radio network (eg, 3GPP LTE or LTE-A system) access, and Wi-Fi 103 is an access point providing local coverage in Wireless Local Area Network (WLAN) access ( access point, AP). In order to better store various radio access technologies, UE101 is a multi-radio terminal (MRT), equipped with multiple radio modules that coexist in the same device platform (ie,...

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.

Description

[0001] Cross References to Related Applications [0002] Scope of Claims of This Application Pursuant to 35 U.S.C. §119 priority is claimed to the following application: U.S. Provisional case. The entire contents of the aforementioned US Provisional Application are hereby incorporated by reference. technical field [0003] The present invention is generally related to wireless communication networks, and more specifically, to wireless-fidelity (Wireless-Fidelity, WI-FI) point-to-point (Point to Point, P2P) and long-term evolution (Long Term Evolution, LTE) data flow coordination. Background technique [0004] Virtually ubiquitous access to the Internet is now possible. From a network infrastructure point of view, different networks belong to different layers (for example, distribution layer, cellular layer, hot spot layer, personal network layer and fixed / wiredlayer (fixed / wiredlayer)) to provide different layers of coverage and connectivity to users. Since the covera...
