  • Patent number: 8553645
    Abstract: A method and apparatus for service continuity on a mobile communication device is disclosed. The method can include receiving (320) a first service on a first carrier, where the first service can have a multicast subframe allocation pattern. The method can include establishing (340) a connection on a second carrier on a universal mobile telecommunication system. The method can include informing (350) a source of the second carrier of the multicast subframe allocation pattern of the first service. The method can include receiving (360) scheduling grants for subframes on the second carrier.

  • Publication number: 20130242911
    Abstract: A cell-specific sounding reference symbol (SRS) subframe configuration and UE-specific SRS configuration are defined for carrier aggregation. For the cell-specific SRS subframe configuration, the same cell-specific SRS subframes are configured for all uplink (UL) carrier components (CCs). For the UE-specific SRS configuration, different configurations are applied for UL CCs. Also, to reduce signaling overhead, the different UE-specific SRS configuration is signaled by using an offset on top of the UE-specific SRS configuration of a primary component carrier (PCC).

  • Patent number: 7187736
    Abstract: A method for reducing interference in a desired signal in a GSM communication system uses a finite-impulse-response filter for alternate linear equalization. The method includes a first step (300) of inputting a burst of data of a received waveform including interference from a channel of the communication system. A next step (302) includes training the finite-impulse-response filter with a set of symbols of specific quadrature phase, known a priori, in the burst of data of the received waveform. For example known real only and imaginary only symbols are alternatively selected from a midamble of the data burst. A next step (304) includes operating on the received waveform with the finite-impulse-response filter to alternately linearly equalize the burst of data to provide an estimate of the desired signal.

  • Patent number: 7130342
    Abstract: A wireless receiver and method employs a forward/backward recursive covariance based filter coefficient generation scheme for equalizing a received wireless signal, such as a CDMA signal or other suitable signal. A forward/backward recursive covariance based filter coefficient generating circuit (206) includes a forward recursion portion (300) that receives data representing channel estimates (18) of a communication channel, and data representing an auto-covariance matrix (22). The forward recursion portion (300) produces a set of output values (306) from each iteration stage (400a–400n) of the forward recursion portion (300). The set of output values (306) are stored and a backward recursion portion (302) obtains the set of output values (306) and also receives the data representing the auto-covariance matrix (22), and generates filter coefficients (208) based on this information.
