  • Publication number: 20110194431
    Abstract: In the context of IEEE 802.11 WLAN networks, enhancement to the Relaxed Deterministic Backoff (R-DEB) for random access of shared (Medium Access Control MAC) method. For all available candidate resource slots, a busy index is calculated that reflects the level of use/occupation in the past and infers a probability of use in the future by another concurring device. The method assumes the use of a sub-set of resource slots for transmission, and updates this set by replacing resource slots for which collisions are frequent with a not currently used candidate resource for which the busy index is the lowest. Passive Spoofing/overhearing of all resources for clear channel assessment (CCS) is used for resource monitoring purposes.

  • Publication number: 20110148673
    Abstract: 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.
