  • Patent number: 8149793
    Abstract: A method of operating a radio network, such as UMTS or cdma2000, which comprises at least one primary station (PS), i.e. and access point or bare station, and a plurality of secondary stations (SSI, SS2, SS3), i.e. mobile stations. The primary station determines the level of interest of the users of the secondary stations in a particular service, such as Multimedia Broadcasting and Multicast Services (MBMS), by allocating a respective plurality of access slots in which the secondary stations can transmit an indication of its interest. The primary station receives the indications of interest to and estimates the level of interest from the number of transmitted indications, for example whether or not they exceed a threshold value. Depending on the result of the estimation process the primary station selects a particular one of at least two transmission modes for transmitting the service.

  • Patent number: 8134929
    Abstract: In a communication system subject to variations in channel quality, transmit power control is used to reduce the variations in received signal quality. If the channel quality degrades to such an extent that a high transmit power would be required to ensure good received signal quality, the transmit power is decreased and is not increased until the channel quality recovers sufficiently to enable an acceptable transmit power level to be used. While the power is at the decreased level, transmission of a data block may continue, or may be suspended, with the data block being truncated if the whole block has not been transmitted by the end of the time period available for transmission of the data block.

  • Patent number: 8130340
    Abstract: A large liquid crystal display (100) comprises a light guide plate (3) arranged on the back side of a liquid crystal panel (1). The front surface of the light guide plate (3) is flat, while the back surface thereof is concave. The upper and lower end faces of the light guide plate (3) respectively facing hot cathode fluorescent lamps (2a, 2b) have a convex shape projecting toward the respective lamps. White light from the fluorescent lamps is incident on the upper and lower end faces of the light guide plate directly or by being reflected by reflectors (4a, 4b), and propagates within the light guide plate while being reflected by the front and back surfaces of the light guide plate. At the front surface of the light guide plate, a part of the white light is directed toward the back side of the liquid crystal panel (1) by a light guide portion (5).

  • Patent number: 8112086
    Abstract: A secondary station has a receiver capable of resolving signals received as a plurality of multipath signals from a plurality of base stations during a soft handover process. This capability may, for example, be provided by a Rake receiver. In order to decode and act upon the received signals in a very short period of time, signals arriving after a predetermined time are not processed by the receiver which is able instead to process weaker signals which arrived before the time. Such a secondary station is particularly suitable for decoding and acting upon power control commands included in received signals in a UMTS system, for which a very limited period of time is provided by the UMTS specification. The predetermined time may be the time after which signals are received too late for use in determining the next power control change.

  • Patent number: 8098771
    Abstract: When transmitting medium access control protocol data units for the high speed downlink shared channel over a plurality of hybrid automatic repeat request processes, one of the processes can be in a retransmission procedure. In this case, stalling of the transmission can occur, because the medium access control layer for the high speed downlink shared channel of the receiver apparatus (3) buffers the following packet data units, when a preceding protocol data unit is waiting in the stalled process. To enable an early processing of the already received data, the receiver apparatus determines, whether the next expected service data units for a higher layer such as a radio link control layer, are included in the already received packet data units by taking into account the sequence number for the higher layer. Therefore, the medium access control layer for the high speed downlink shared channel accesses the data of the service data unit for the higher layer.

  • Patent number: 7857308
    Abstract: According to an embodiment, an idler roller has an insertion through-hole through which a rotation shaft is inserted. Collar-shaped stopper portions are formed on the rotation shaft and are located on both left and right sides of the idler roller when the rotation shaft is inserted and provided at a normal position. Coil springs are attached between the stopper portions and base surfaces of concave groove portions of the idler roller. The idler roller is held at the normal position by biasing force of both the coil springs when paper is not seized. When paper is seized, the idler roller is moved in a lateral direction by elastic restoring force caused by a torsion phenomenon occurring in the paper. The idler roller returns to the normal position due to biasing force of both the coil springs after the paper has passed through the idler roller.

  • Patent number: 7810007
    Abstract: Using the attribute “priority” to achieve a stronger Forward Error Correction (FEC) for Radio Link Control (RLC) Control Protocol Data Units (PDUs) transmitted via the High Speed Downlinik Shared Channel (HS-DSCH) also entails prioritized handling so that an RLC Control PDU is likely to overhaul an RLC Data PDU. As a consequence the RLC protocol operation can severely be disturbed, since it relies on in-sequence delivery of control and data PDUs. According to an exemplary embodiment of the present invention, two types of containers are provided in which data packets may be transmitted, wherein the first type of container is provided with a stronger error coding than the second type of container and wherein data packets which comprise control instructions are only transmitted in the first container type with the stronger error correction. Due to this, an improved forward error correction for control PDUs of the AM RLC protocol of Universal Mobile Telecommunications System (UMTS) may be provided.

  • Patent number: 7783895
    Abstract: A controller of a recording device issues a secure command to a storage device, and then waits the time estimated necessary for the storage device to execute the secure command before issuing the next secure command. When a controller of the storage device is executing the previous command, it notifies the recording device of being in process. When the previous command has been completed normally, the controller moves to the next process. Information for estimating the execution time of the command is obtained from the storage device in advance.
