Abstract:
1. A wireless communication device for sharing a network connection, the wireless communication device comprising: a wireless local area network (WLAN) chipset; a cellular chipset; and an application processor comprising a first portion and a second portion, the first portion of the application processor comprising at least one root complex powered via a dedicated power domain, the dedicated power domain being independent of at least one second power domain configured to power the second portion of the application processor; wherein the WLAN chipset is coupled to a first port of the at least one root complex via a first Peripheral Component Interconnect Express (PCIe) bus interface; wherein the cellular chipset is coupled to a second port of the at least one root complex via a second PCIe bus interface; wherein the wireless communication device is configured to share a connection to a cellular network supported by the cellular chipset with a tethered device coupled to the wireless communication device via a WLAN connection supported by the WLAN chipset; and wherein the at least one root complex is configured to use power received via the dedicated power domain to implement a peer-to-peer (P2P) function to bridge the WLAN chipset and the cellular chipset to convey data exchanged between the tethered device and the cellular network while the second portion of the application processor is sleeping.
