  • Patent number: 8937907
    Abstract: A method and apparatus for extended access barring (EAB) in a wireless communication system. In detail, the present description proposes EAB indication information, which is included in the paging message. The EAB indication information is included in the paging message only when as least one access class (AC) is barred by EAB operation of the network. Alternatively, the EAB indication information can be included in the paging message when EAB information in a system information block (SIB) has been changed or updated. Further, the present description proposes a timer associated with the EAB indication information. The timer is used to ensure the validity of the EAB indication information to the UE while the timer is running by a user equipment (UE). While the timer is running, a specific value or information indicated by the EAB indication information in a paging message is assumed to be valid/correct by the UE.

  • Patent number: 8634387
    Abstract: In one embodiment, a first system receives N data transmissions from a second system. The first system combines N ACK/NACK responses, corresponding to the N data transmissions received, and encodes the combined N ACK/NACK responses by selecting a position of a communication channel over which the first system sends ACK/NACK transmissions to the second system and setting a value for each bit sent during each ACK/NACK transmission based on the combined N ACK/NACK responses. The first system sends the bits at the selected position of the communication channel. The second system, upon receiving the bits sent at the selected position of the communication channel, decodes the N ACK/NACK responses based on the position at which the bits are sent and the bits.

  • Patent number: 8451817
    Abstract: A method and apparatus for determining if a packet is a duplicate packet are disclosed. The method includes determining if a field of a duplicate packet map (DPM) indicates the packet is the duplicate packet. The determination is made using a packet summary value (PSV) corresponding to the packet. The apparatus (a network device, for example) includes a duplicate packet map (DPM), which can be used to make the foregoing determination.
