20100177807 | METHOD AND APPARATUS FOR RELAYING WIRELESS TRAFFIC IN A WIRELESS NETWORK - A relay station to relay wireless traffic between a base station and mobile stations. The relay station receives incoming subframes of OFDM symbols and transmits outgoing subframes of OFDM symbols. The relay station comprises a timing offset controller configured to control the transmission of a first outgoing subframe with respect to reception of a first incoming subframe, such that the first outgoing subframe either leads or lags the reception of the first incoming subframe by a first time offset. The first time offset is equal to at least one OFDM symbol. | 2010-07-15 |
20100177808 | METHOD AND DEVICE FOR TRANSFERRING DATA - The invention relates to a method including a step of providing a clock having a clock period, wherein an integer multiple of the clock period defines a periodic time grid. In a further step, data packets are transferred between a baseband assembly and a radio-frequency assembly, wherein the times of the start of the transfers are offset with respect to the times of the periodic time grid. | 2010-07-15 |
20100177809 | Physical layer device having an analog SERDES pass through mode - A physical layer device (PLD) includes a first serializer-deserializer (SERDES) device and a second SERDES device. Each SERDES device includes an analog portion with a serial port that is configured to communicate serial data with various network devices, and a digital portion that is configured to communicate parallel data with other various network devices. The PLD includes a first signal path that is configured to route serial data signals between the analog portions of the SERDES devices, bypassing the digital portions of the SERDES devices. Therefore, the SERDES devices can directly communicate serial data without performing parallel data conversion. A second signal path is configured to route recovered clock and data signals between the analog portions of the SERDES devices, but still bypassing the digital portions of the SERDES devices. The recovered clock and data signals are then regenerated before being transmitted over a network device. | 2010-07-15 |

20100177812 | MANAGING AVAILABILITY STATUS IN A COMMUNICATIONS NETWORK - A system and a method are disclosed for a presence engine and a method of operating a presence engine for encoding or decoding availability status into a signal representative of an audio signal. The presence engine is configured to manage availability status of a user. The presence engine comprises an input configured to receive a signal representative of an audio signal and an output configured to send a signal representative of an audio signal. The presence engine also comprises a processor configured to encode availability status of a user into a signal representative of an audio signal and/or configured to decode availability status of a user from a signal representative of an audio signal. | 2010-07-15 |
20100177813 | Evaluation of the Feedback Quality in Communications Systems - A measuring system is used for testing a feedback signal transmitted by a communications device within a communications system. The measuring system comprises an antenna system and a measuring device. The measuring device transmits a signal to a communications device via the air interface and the antenna system. The communications device receives the signal and generates a feedback signal dependent upon transmission conditions of the signal, which it has determined, and transmits it to the measuring device. The measuring device measures the actual reception quality of the signal in the communications device. In this context, the measuring system implements the following stages: | 2010-07-15 |
