Patent number: 8243659Abstract: The invention is directed to efficient transfer of low bit rate services in a communication system. A synchronization symbol which has known characteristics may be included as a first symbol of digital broadcast frames. The synchronization symbol, which can be decoded without having to resort to trial and error methods, contains parameters for the rest of the signal. Low bit rate services are allocated to time slots following the pilot symbol used for synchronization allowing for fast access times with maximum power saving capabilities. A user terminal wakes up just before the synchronization symbol and received the data allocated for the low bit rate services. The user terminal may power off for the remaining time slots which are allocated for higher bit services to conserve power.Type: GrantFiled: March 15, 2007Date of Patent: August 14, 2012Assignee: Nokia CorporationInventors: Jukka Henriksson, Jussi Vesma, Jani Väre, Harri J.

Patent number: 7940798Abstract: A terrestrial digital video broadcasting (DVB-T) network is used to transmit IP datagrams to receiving devices using multiprotocol encapsulation (MPE). MPE datagram section and, if forward error correction (FEC) is used, MPE-FEC datagram sections may include time-slicing parameters, such as a “delta-t” parameter for specifying a time until the next burst is transmitted and a flag for indicating the end of a burst. Thus, MPE and MPE-FEC datagram sections can be transmitted in bursts. Other types of sections, however, do not include such time-slicing parameters and thus cannot usually be transmitted in bursts. Nevertheless, by assembling a burst including at least one MPE or MPE-FEC datagram section which specifies delta-t and MPE or MPE-FEC datagram section at the end of a burst which indicates its position, other types of sections can benefit from being transmitted in bursts.Type: GrantFiled: May 26, 2004Date of Patent: May 10, 2011Assignee: Nokia CorporationInventors: Matti Puputti, Tommi Auranen, Kimmo Laiho

Patent number: 7787548Abstract: Aspects of the invention are directed to service and channel discovery in a digital broadcast network. A pilot synchronization symbol, which has known characteristics, is included as a first symbol of digital broadcast frames. The pilot symbol, which can be decoded without having to resort to trial and error methods, contains parameters for the rest of the signal. So, the rest of the signal can be decoded without trial and error methods after the pilot symbol (and any additional synchronization symbols) is decoded. Channels containing digital video broadcast services can be efficiently detected using the known part of the signal. If the fixed known part is not found from the examined signal, then the signal will be considered a non-digital-video-broadcast signal or an empty channel, and the receiver can promptly proceed to a next channel/frequency. In this way, detecting non-digital-video-broadcast and empty channels becomes relatively fast.Type: GrantFiled: March 15, 2007Date of Patent: August 31, 2010Assignee: Nokia CorporationInventors: Tommi Auranen, Harri J.

Patent number: 7620120Abstract: A method is performed in a receiver including a number of modules. The method includes receiving information in a reception frequency band. Responsive to a notification from a transmitter of a transmission in a predetermined transmission frequency band, at least one countermeasure is performed by at least one of the modules. The at least one countermeasure is predetermined to reduce an effect of interference caused by transmission on reception of the information in the reception frequency band. Countermeasures include freezing an automatic gain control loop, freezing a synchronization loop, discarding channel estimation data, and blanking received information. Transmission power and transmission mode are also used to determine whether and how many countermeasures are used. Additionally, handover is improved by waiting until transmission is complete to determine receiver signal strength of signals from potential transmitters for handover.Type: GrantFiled: September 19, 2005Date of Patent: November 17, 2009Assignee: Nokia CorporationInventor: Tommi Auranen
