摘要： Disclosed are voltage distribution device and method for controlling CMOS-based devices for switching radio frequency (RF) signals. In certain RF devices such as mobile phones, providing different amplification modes can yield performance advantages. For example, a capability to transmit at low and high power modes typically results in an extended battery life, since the high power mode can be activated only when needed. Switching between such amplification modes can be facilitated by one or more switches formed in an integrated circuit and configured to route RF signal to different amplification paths. In certain embodiments, such RF switches can be formed as CMOS devices, and can be based on triple-well structures. In certain embodiments, various bias voltages applied to such a CMOS RF switch can be facilitated by a voltage distribution component.

摘要： Base station assisted peer to peer discovery methods are described. A wireless terminal communicates peer discovery expression information to a base station and information identifying a peer discovery resource that it intends to use but which may also be used by other devices. The base station associates the peer discovery expression and peer discovery resource with an index value to be communicated on the peer discovery resource. The base station transmits the peer discovery expression and information associating the peer discovery expression with the peer discovery resource and the index value. The wireless terminal transmits the index value on the peer discovery resource. A wireless terminal receiving the index value determines the peer discovery expression being communicated using information from the base station. Use of different indexes allows multiple devices to use the same discovery resource.

摘要： To maintain a synchronized wireless peer group, timing signals may be periodically transmitted by one or more devices in the wireless peer group. These periodic timing signals may be transmitted by different wireless devices in the peer group, distributing (sharing) the transmit power burden among the different wireless devices, increasing the useful operation time of the individual wireless devices. Similarly, the wireless peer group may monitor for timing signals received from devices that are not part of the wireless peer group. This monitoring burden may also be distributed (shared) among the devices in the peer group allowing for a greater sleep time for individual wireless devices, increasing the useful operation time of the individual wireless devices.
