| 261 | POWER MANAGEMENT & CONTROL SYNCHRONIZATION WITHIN IN A WIRELESS NETWORK USING MODAL ANTENNAS AND RELATED METHODS | US13523678 | 2012-06-14 | US20130150040A1 | 2013-06-13 | Laurent Desclos; Sebastian Rowson; Jeffrey Shamblin |
| A means of power management and control via a reverse link of a CDMA or LTE network is disclosed. The protocol is set to superimpose itself in an agnostic way to the power management as one more layer of freedom is added. The adjustment depending on the power control is then derived by mismatch if too much power or antenna tuning to enhance the power. This is also following a table in the device that will adjust ECC in case of a MIMO transmission such as LTE as well as SAR. This will generate also a mean of a soft-handoff and load control on the base station. | ||||||

| Paging and power consumption are managed in conjunction with providing local breakout in a wireless wide area network. In some aspects, if a packet destined for an access terminal is received at an access point that provides local breakout, the access point may inform the network so that the network will cause the access point to page the access terminal. Alternatively, in some aspects an access point that provides local breakout may maintain idle context of the access terminal, whereby the access point may autonomously page the access terminal (i.e., without involving the core network). In some aspects local breakout traffic is filtered at an access point to reduce the number of pages or packets sent to an access terminal. In some aspects an indication of a packet type is provided with a page message to enable an access terminal to determine whether to receive the packet. In some aspects a local link interface may be selectively disabled or enabled to limit traffic at an access terminal. | ||||||
