| 20110080882 | Reservation of Spectrum Resources in White Spaces - A white space entity reserves spectrum in white space from a reservation system. Consequently, the white space entity may utilize television bands that are unused at a specified time period and geo-location in order to support different services such as wireless audio transmission, networking, video surveillance, and video conferencing. The white space entity requests reservation of spectrum resources from the reservation system by sending a reservation request. The request includes request parameters that may include geo-location, model number or manufacture code number, priority of entity, reservation time period, and maximum power level. The reservation system consequently verifies the request from the priority of the white space entity and the availability of white space spectrum for the desired time period. The white space entity then extracts confirmation parameters from a reservation confirmation message and subsequently transmits on white spectrum in accordance with the parameters. | 04-07-2011 |

| 20100263012 | Layered Coded Streaming Control For Unicast/MBMS Interaction - A higher network sends a base stream of a data stream to a first network node, and sends an enhancement stream of the data stream to a second network node. The first network node transmits the base stream over a multicast channel and the second network node transmits the enhanced stream in synchronism with the transmitted base stream over a unicast channel. Various options are detailed for how this synchronism is achieved, and the second network node need only transmit the higher bit-rate enhancement stream on user request or if network conditions permit. A user equipment receives the base and enhancement streams, combines them, and displays the combined stream to a user at a graphical display interface. Various apparatus, methods, and computer programs are detailed for various nodes and the user equipment. | 10-14-2010 |

| 20080261531 | SYSTEM AND METHOD FOR PROVIDING COVERAGE AND SERVICE CONTINUATION IN BORDER CELLS OF A LOCALIZED NETWORK - A system and method for providing continuous multimedia broadcast multicast services over different localized areas, while also avoiding frequency interference. In various embodiments, a service provides reduced-quality data at the border of each localized area. In one approach, border cells of a single frequency network (SFN) broadcast reduced quality data, while more centralized cells in a SFN broadcast full quality data. In other embodiments, source data is coded by two layers—a baseline layer and at least one enhancement layer. Centralized cells in a SFN transmit both baseline and enhancement layers. Border cells broadcast only the baseline layer. Centralized cells and border cells use the same sub-band to broadcast baseline layer data in a bit-identical way. Non-overlapping sub-bands are used by border cells of neighboring SFNs to transmit the baseline layer. | 10-23-2008 |
| 20090254789 | CODING A SIGNAL - An apparatus, a base station and user equipment are provided. The apparatus is configured to code a first given number of symbols from the beginning of a transmission period and/or a second given number of symbols from the end of the transmission period with a stronger error correcting code than the rest of the symbols in the transmission period. | 10-08-2009 |

In another embodiment, the apparatus includes a measurement report handler configured to process a reliability report received from a user equipment and an interference coordination subsystem configured to adjust interference coordination parameters based on the reliability report received from the user equipment. | 10-30-2008 |
| 20080274759 | System and Method for Controlling Base Stations for Multimedia Broadcast Communications - A method, apparatus and system are provided for controlling base stations for multimedia broadcast communications. In one embodiment, an apparatus includes a reporting subsystem configured to compile an activity status report based on a counting report and a channel quality indicator report received from user equipment and to send the activity status report to an entity of the communication system. The apparatus also includes a dynamic single-frequency network subsystem configured to control a multimedia broadcast and multimedia multicast service provided by the apparatus as a function of a static contribution table associated therewith and the activity status report. | 11-06-2008 |
| 20090103484 | Designing Power Sequences - The invention relates to the design of power sequences for use in a group of sub-areas of a wireless communication system. Each power sequence defines for one of the sub-areas transmission power values for transmissions using a respective one of a plurality of medium access units. For each of the sub-areas of the group, reception quality values are determined for transmissions between an access station serving the sub-area and mobile stations located at an edge of the sub-area. The reception quality values allow meeting system. The reception quality values are then converted for each of the sub-areas into transmission power values of a power sequence. | 04-23-2009 |
