20140099106 | Method and Apparatus for Aligning and Integrating Serial Data Streams - An integrated circuit is incorporated into a communications system to enable a channel to achieve data rates that are at least double that which are currently achievable. The integrated circuit combines serial data signals using recovered clock and serial data signals in reference and non-reference clock domains. The integrated circuit rate converts recovered serial data in one of the clock domains, performs a phase alignment at the converted data rate, and returns the rate converted and phase-aligned serial data to the recovered data rate in response to the recovered clock from the remaining clock domain. Thereafter, the recovered and aligned serial data signals are combined. The phase alignment is monitored in circuitry that detects when a threshold offset is violated. When the threshold offset is violated a synchronization circuit is enabled. | 04-10-2014 |

20150103817 | GLOBAL TIME SYNCHRONIZATION SERVER FOR WIRELESS DEVICES - Synchronization of communication events according to a global time base (GTB). Devices implementing the GTB may be configured to awaken and exchange discovery and service capability information over pre-scheduled channels at time points determined according to the GTB. The GTB may be correlated to Global Positioning System (GPS) system time. A global time server (GTS) is described for providing a local source of accurate clock time relative to the GTB. The GTS may aggregate multiple sources of absolute and/or relative time including GPS and WWAN, select the most accurate source for a mobile environment, track source state transitions, and manage clock drift. Global time clients (GTCs) may receive updates from the GTS and compute offsets for communication events relative to a local clock. The GTC may correct for transport errors from transmission of the updated global time value across modules or sub-components of the devices. | 04-16-2015 |

20150103715 | DOWNLINK CONTROL FORMAT INDICATOR - Methods, apparatuses, systems, and devices are described for wireless communication. In one method, a control format indicator value for a frame may be received over a physical carrier in a shared spectrum. Based on the control format indicator value, a number of subframes of the frame to be used by a base station for downlink transmissions over the physical carrier may be determined. The control format indicator value may indicate an end of transmission, if data is to be transmitted during the frame, a number of subframes to be used for transmission, or whether the current subframe is the final subframe used for transmission. In some cases, a user equipment (UE) may use the control format indicator value to determine a sleep schedule. Further, ACK/NACK transmissions by a UE may be scheduled based on the control format indicator value. | 04-16-2015 |
