20110320841 | Method for power management of data buses in electronic devices - Provided are systems and methods for execution by a core of a peripheral component to provide power management for a data bus in a electronic device, suhc as a mobile electronic device. One method comprises determining whether a device in the peripheral component is inactive, transmitting a request for deactivation of at least one data channel to the device, receiving a command to deactivate the at least one data channel, determining whether any remaining devices in the peripheral component are active, and placing the peripheral component in a first low power mode wherein the core remains active in order to monitor a data bus clock. | 12-29-2011 |
20120327829 | Method and System for Allocating Bandwidth for Data Transmissions Between High-Speed Wireless Devices - According to one disclosed embodiment, a method for allocating bandwidth for data transmission time between high-speed wireless devices includes providing beacon intervals to accommodate allocation of data transmissions, each beacon interval including a data transmission time (DTT) interval, dividing all DTT intervals into timeslots of substantially uniform duration, and allocating an integer multiple of the timeslots to each of a plurality of service periods for timed data transmission. Such a method may further include allocating each service period of an isochronous traffic stream to begin the same number of timeslots from the beginning of its beacon interval, dividing the allocation of an asynchronous traffic stream over its allocation period by allocating an equal number of timeslots to a service period in each beacon interval within the allocation period, and de-allocating one or more service periods by marking as unallocated timeslots previously allocated to those service periods. | 12-27-2012 |
20130003662 | Method and system for reliable service period allocation in 60 GHz MAC - A technique to send service period allocation from a network control point to a plurality of stations using an Announce frame of a 60 GHz DBand specification. The use of the Announce frame ensures that the control point receives confirmation of the service period allocation assigned to the stations before data transfer is permitted between the stations. | 01-03-2013 |
20130095768 | System and Method for Scanning Wireless Channels - System and method for active scanning of wireless channels is described. An example method may include transmitting, by a first wireless device, a request to enter a sleep mode and a sleep mode schedule to a second wireless device, the sleep mode schedule specifying a sleep period for the first wireless device going to sleep, and scanning one or more wireless channels, by the first wireless device after transmitting the sleep mode schedule and during the sleep period, to find a third wireless device for communication with the first wireless device. The method may also include communicating, by the first wireless device, during the sleep period, with the third wireless device. Such a scan may be a passive scan or an active scan. | 04-18-2013 |
20130329576 | NOVEL METHODS FOR EFFICIENT POWER MANAGEMENT IN 60GHZ DEVICES - A device and method for managing power in a wireless telecommunication system. A telecommunication device operates in a power saving mode during a sleep interval whenever possible to minimize power drain. The telecommunication device monitors various device, channel and network parameters and dynamically adjusts the duration of the sleep interval based on the monitored parameters in order to optimize power savings. | 12-12-2013 |
20140369330 | Assisted Device Discovery - An electronic device may communicate according to a first communication standard and a second communication standard. The first communication standard may have a longer communication range than the second communication standard. The electronic device may send a capability indication through the first communication standard. The capability indication may indicate the electronic device is capable of communicating according to the second communication standard with a shorter communication range than the first communication standard. The electronic device may discover a second electronic device capable of communicating according to the second communication standard and positioned outside of a non-extended communication range of the second communication standard. Upon discovery, the electronic device may communicate with the second electronic device at an extended range of the second communication standard even though the second electronic device is positioned outside the non-extended communication range of the first electronic | 12-18-2014 |
20150082064 | Power Management in a Configurable Bus - A system includes a bus and a component interconnected via the bus. The component may enter a sleep mode during a period of no data transmission involving the component. | 03-19-2015 |
20150103756 | Efficient Beacon Transmission and Reception - A control point, such as a laptop, phone, wireless access point, or other device, transmits beacons to receiving stations in a wireless network. The control point may reduce power and bandwidth consumption by transmitting beacons with smaller payloads and/or less frequently to sectors with no associated stations. The stations, which may include laptops, phones, or other devices may reduce power consumption be powering on their antennas when beacons may be transmitted to their sectors. | 04-16-2015 |
