  • Publication number: 20070211657
    Abstract: In order to address the above-mentioned need, a method and apparatus for assigning time-domain resources to a wireless receiver is provided herein. During operation a resource assigned to a particular node will comprise a particular-length subframe having a unique combination of a number of contiguous slots and a slot start time. The subframe will repeat after a predetermined number of slots to form a subframe pattern. For a given frequency resource (group of subchannels), each node to which the base station is transmitting a packet will have a unique subframe length, starting slot, and repetition time period. Because each node will be assigned a subframe pattern having a particular length, and because each node's transmissions will begin at varying slots, the resources may be assigned to multiple nodes without having any transmissions overlap.

  • Publication number: 20070183385
    Abstract: An apparatus and method of distinguishing a frame on a channel shared by a plurality of users. A unique identifier can be obtained for each of a set of mobile communication devices. A message intended for one of the mobile communication devices can be obtained. The message can be scrambled using a long code generated using a mobile communication device specific long code mask to obtain a scrambled message. The unique identifier can be incorporated into the scrambled message for a frame intended for a selected mobile communication device. The frame can then be transmitted. A radio frequency signal can be received for the frame. Demodulation can be performed on the signal to obtain a scrambled signal. A unique identifier can be extracted from the scrambled signal. The unique identifier extracted from the scrambled signal can be examined to determine if the signal is intended for a mobile communication device.

    Abstract: A method and apparatus for sharing a unique identifier among a plurality of receivers. A network controller (140) can establish at least one unique identifier and at least one corresponding time slot for which the unique identifier is valid for each assigned carrier of a wireless receiver (120). The network controller does this by determining at least one unique identifier and at least one corresponding time slot for which the unique identifier is valid for each assigned carrier of the wireless receiver and then sending an indication of the unique identifier(s), time slot(s), and carrier(s) to the wireless receiver. The wireless receiver receives the indication and then monitors at least one channel using the at least one unique identifier during the at least one corresponding time slot indicated.
