    摘要: A method and apparatus are therefore provided that may enable the provision of M2M communication in a wireless network environment. In this regard, for example, relatively low power devices (specifically referencing low transmission power) such as sensors or other machines in an M2M system may be enabled to initiate communication with a network through a mobile terminal in a more reliable and robust manner. The machine may transmit a busy-signal to request a reservation of a machine access slot on a machine access control channel to reserve the slot before transmitting any machine information or data to reduce the likelihood of collisions with other machines. Once the machine has reserved the machine access slot, the machine may transmit identification information via randomly selected frequency division multi-plexed or code division multiplexed resources to further reduce the likelihood of collisions with other machines. Thus, delays in establishing connections may be reduced or eliminated.

    摘要: A source sends an encoded data block during a first time interval to a destination and to a relay. The source sends additional parity bits for the encoded data block during a second time interval. The relay partially decodes that encoded data block to a process-defined end point (typically only a partial decoding), such as a fixed number of decoding iterations. After partial decoding the relay forms a modified data block having corrected information bits and the parity bits of the block it received, and sends the modified data block to the destination, during the second time interval. The destination decodes to a results-defined end point the modified data block it received from the relay using the additional parity bits it received from the source. If that end-point cannot be reached, the destination may begin anew decoding the original encoded data block it received from the source.

    摘要: A network access node selects one chunk of spectrum from a plurality of chunks of spectrum to be a primary chunk for a particular cell; transmits in the primary chunk from a broadcast channel BCH that contains information needed by a terminal to at least perform initial cell access; and uses a synchronization channel SCH to indicate which chunk of the plurality of chunks is the primary chunk. A user equipment receives a SCH in a particular chunk of spectrum; determines from it that one chunk is a primary chunk for a particular cell; tunes its receiver to a BCH in the primary chunk and uses information received on the BCH to obtain initial access to the particular cell. In various embodiments the SCH is only in the primary chunk or the SCH has some indication (e.g., cell ID or relative position of primary chunk) telling which chunk is primary.

    摘要: Disclosed herein are apparatus, methods and computer program products for performing cell acquisition and pilot sequence detection in a cellular telecommunications system such as, for example, an OFDM system. In the apparatus, methods and computer program products, a primary synchronization channel sequence and a secondary synchronization channel sequence are transmitted by a base station in a sub-frame of an OFDM downlink frame. In one embodiment, the primary synchronization channel sequence, secondary synchronization channel sequence, and system information are mapped to a plurality of sub-carriers in an FDM signal. At the user equipment, coarse synchronization is performed during cell acquisition by performing a cross correlation between the signal and a reference primary synchronization channel sequence stored in a memory of the user equipment. The coarse synchronization performed using the primary synchronization channel sequence is improved by performing a cross correlation between the signal and a reference secondary synchronization channel sequence stored in a memory of the user equipment. Identification of a pilot sequence for channel estimation purposes is performed by detecting two cyclically invariant pairs of secondary synchronization channel sequences over two consecutive frames of the signal. The cyclically invariant pair of secondary synchronization channel sequences are selected from a set of orthogonal sequences and identify a particular pilot sequence incorporated in the signal.
