The method for processing a downlink subframe at a user equipment in a wireless communication system includes receiving information associated with a PHICH duration, receiving a subframe that includes a PHICH, a PDCCH, and a PDSCH, and obtaining the PDSCH after a lapse of the PDCCH duration. If the PHICH duration is larger than the PDCCH duration, the obtaining of the PDSCH is performed in consideration of PHICH resources in a duration that corresponds to the PHICH duration but not to the PDCCH duration.2012-02-09
20120033651Methods and Devices for Scheduling Transmissions in a Wireless Network Based on Contention and Channel Conditions - Methods and systems for assigning time-division multiplexed (TDM) slots in a multi-channel TDM system are presented. Preferably, a radio access network (RAN) assigns forward link and reverse link transmissions between the RAN and one or more wireless communication devices (WCDs) to TDM slots on various wireless channels. When making these assignments, the RAN may take into account (i) the priority of data that the RAN queues for the WCDs, and (ii) the signal quality at which the WCDs can receive the various wireless channels.2012-02-09
20120033652System and Method for Simultaneous Infrastructure and Ad Hoc Networked Communications - A method and a system are disclosed for maintaining a simultaneous communication between a first wireless station and both an access point and a second wireless station. The first and second wireless stations are associated with the access point, or only one of the wireless stations, but not both, is associated with the access point. The first wireless station gains an instance of medium access by using applicable medium access protocols. Once the first wireless station gains an instance of medium access, it transmits frames to the access point on an infrastructure network and to the second wireless station on the same infrastructure network or an ad hoc network. The overall air time must not exceed the maximum air time allowed for the instance of medium access. All transmitted frames must have a user priority mapped to the access category for which the instance of medium access was obtained.2012-02-09
20120033653WIRELESS MOBILE COMMUNICATION DEVICE WITH AUTONOMOUS WI-FI CONTROL BASED ON MOTION OF DEVICE - A wireless mobile communication device may include a Wi-Fi data communication system, an operational condition detection system, and a Wi-Fi activation system. The operational condition detection system may be configured to detect an operational condition of the wireless mobile communication device, other than actuation of a user-operated control. The operational condition may be when a motion sensor senses that the wireless mobile communication device has been substantially motionless. The Wi-Fi activation system may be configured to autonomously turn power on to the Wi-Fi data communication system upon detection of an operational condition of the wireless mobile communication device by the operational condition detection system, other than actuation of a user-operated control.2012-02-09
20120033654WIRELESS MOBILE COMMUNICATION DEVICE WITH AUTONOMOUS WI-FI CONTROL BASED ON LOCATION OF DEVICE - A wireless mobile communication device may include a Wi-Fi data communication system, an operational condition detection system, and a Wi-Fi activation system. The operational condition detection system may include a location sensor. The operational condition detection system may be configured to detect an operational condition of the wireless mobile communication device, other than actuation of a user-operated control, including when the location sensor determines that the wireless mobile communication device is near a Wi-Fi access point. The Wi-Fi activation system may be configured to autonomously turn power on to the Wi-Fi data communication system upon detection of an operational condition of the wireless mobile communication device by the operational condition detection system, other than actuation of a user-operated control, including when the location sensor senses that the wireless mobile communication device is near a Wi-Fi access point.2012-02-09
20120033655DIGITAL CAMERA DEVICE AND GEOGRAPHY TAG OBTAINING METHOD - A digital camera device is located within a wireless local area network (WLAN) which includes a plurality of wireless stations and access points (APs). The digital camera device detects no AP and then detects one wireless station. The digital camera device transmits a disconnection management frame to the detected wireless station by way of pretending to be one of the APs communicating to the detected to the wireless station to notify the detected wireless station to disconnect from the one of the APs. The digital camera device receives a reconnection management frame transmitted by the wireless station to the AP, retrieves a service set identification (SSID) of the AP from the reconnection management frame, and obtains a geography tag according to the retrieved SSID.2012-02-09
