    Abstract: A method in a wireless communication device (103, 110) comprises attempting to decode combined control channel elements received at the wireless communication device, determining whether the attempted decoding of the combined control channel elements is successful, and attempting to decode a single control channel element if the attempt to decode the combined control channel elements is not successful

    IPC: H04J11/00

    Abstract: A method and apparatus is provided for transmitting an orthogonal frequency domain multiple access (OFDMA) signal including a synchronization channel signal transmitted within a localized portion of a bandwidth of the OFDMA signal (818), the synchronization channel signal having predetermined time domain symmetry within the localized portion of the bandwidth (816). The synchronization channel signal enables an initial acquisition and cell search method with low computational load which provides OFDMA symbol timing detection and frequency error detection by differential processing of sequence elements of the synchronization channel signal (1112) and frame boundary detection and cell specific information detection (1114) in an OFDMA system supporting multiple system bandwidths, both synchronized and un-synchronized systems, a large cell index and an OFDMA symbol structure with both short and long cyclic prefix length.

    IPC: H04L27/26

    Abstract: A wireless communication terminal (103, 110) and scheduling entity and methods therein including providing a radio resource allocation having a plurality of sub-carriers that are a subset of available sub-carriers to a wireless communication terminal, wherein the available sub-carriers include a DC sub-carrier. If the DC sub-carrier is between any two sub-carriers of the allocation, the DC sub-carrier and all but one edge-most sub-carrier of the plurality of sub-carriers are designated for transmission. If the DC sub-carrier is not between any two sub-carriers of the allocation, all of the sub-carriers except the DC sub-carrier from the plurality of sub- carriers are designated for transmission.

    Abstract: A method and apparatus for interrupting a transmission of a multicast signal includes a common channel selector (106) coupled to a receiver (102) to receive common channel information (116) therefrom. A repetition value calculator (108) receives measurement occasion information (118) from the common channel selector (106) to calculate a repetition factor (120). A system frame number comparator (110) determines if a channel measurement occasion (128) should be performed based on the repetition factor (120), a common identifier (124) and a largest common channel transmission time interval (122). The method and apparatus further includes a measurement occasion generator (112) coupled to the system frame number comparator (110), wherein if a measurement occasion is to be performed, a measurement occasion command signal (126) is provided to the measurement occasion generator (112) and the measurement occasion generator generates the channel measurement occasion (128).

    Abstract: Un dispositivo 200 de comunicaci?n inal?mbrica que incluye un primer codificador CRC que genera un primer bloque de bits de paridad CRC en un bloque de transportaci?n y asocia el primer bloque de los bits de paridad CRC con el bloque de transportaci?n, una entidad de segmentaci?n que segmenta los bloques de transportaci?n en m?ltiples bloques de c?digo despu?s de asociar, y un segundo codificador que genera un segundo bloque de los bits de paridad CRC en cada bloque de c?digo y asocia un segundo bloque de los bits de paridad CRC con cada bloque de c?digo. El primer y segundo bloques de los bits de paridad CRC se basan en el primer y segundo polinomios del generador. En la modalidad, el primer y segundo polinomios generadores son diferentes. En otra modalidad, los polinomios generadores son los mismos y el bloque de transportaci?n se intercala antes de segmentar o el bloque de c?digo se intercala antes de codificar con el segundo bloque de los bits de paridad CRC.
