    摘要: A method for scheduling wake/sleep cycles by a central device in a wireless network is provided. The wireless network comprises at least one mobile device. The method comprises: attributing a wake/sleep cycle length to each mobile device, wherein the wake/sleep cycle length is an integer multiple of a system schedule cycle; assigning a sleep period and a wake period within the wake/sleep cycle of each mobile device; and arranging the wake/sleep cycle of each mobile device to avoid collision of the wake period with those of other mobile devices. The present invention can keep the maximum sleep cycle period of each MS to guarantee the QoS requirement and to efficiently utilize the system bandwidth.

    摘要: It provides a method for encoding a set of elements by using components defining the structure of each of the set of elements, wherein each element comprises data structure information and at least one data value. The method comprises the steps of: selecting a current element for encoding; determining whether the current element has the same data structure information as a previously encoded element; in the negative, encoding the data structure information of the current element and the at least one data value of the current element; and in the affirmative, encoding the at least one data value of the current element and providing an indication value associated with the current element indicating the current element has the same data structure information as said previously encoded element. The method is used to reduce the encoding redundancy of the structure information.

    摘要: An adaptive and scalable packet error correction apparatus and method in a wireless multicast network is provided. Each retransmission request from a receiver contains a round number and the number of repairs sent in that round. At each receiver, there are two counters for counting the rounds sent out on the network and the number of repairs that have been required. A receiver on the wireless multicast network listens to the ARQ requests sent by other receivers to update the two counters and determines whether its request should be suppressed or be sent out.
