摘要： The system and method of the present invention provide a protocol for a device (400) to announce that a previously reserved time-period or time-slot is not (completely) used and becomes available, so that other devices can transmit during the unused time. The system and method are especially intended for systems with distributed medium reservation by the devices, i.e., those systems adhering to a distributed reservation protocol (DRP).

摘要： A method and system for efficiently utilizing frequency spectrum resources is disclosed. The method comprises the steps of determining at least one spectrum opportunity (510), wherein the opportunity is identified by a frequency range and a time duration, determining a set of altered transmission characteristics (515, 517) to allow transmission of a desired signal in the identified frequency range, wherein the altered transmission characteristics avoid interference with signals expected in the frequency range, and transmitting said desired signal using the altered transmission characteristics when the transmission occurs during said time duration. In one aspect of the system, the step of determining at least one opportunity comprises the steps of receiving signals in known frequency ranges, and determining the characteristics of the received signals. The system comprises a receiving unit (1001) for receiving information items regarding at least one receivable signal, a processing unit (862) for determining characteristics of the at least one received signal, a managing unit (864) for altering transmission characteristics of a desired signal based on the determined received signal characteristics, wherein the altered transmission characteristics avoid interference with the received signals and a transmission unit (866) receiving said altered transmission characteristics to transmit said desired signal. In one aspect, the desired signal transmission characteristics are altered in a frequency range/time period to avoid interference with received signals in the frequency range.

摘要： A plurality of methods, computer program product, and apparatus that use a lower 32 bit field of a 64-bit 802.11 TSF timer, so as to encode the reference time instant without the ambiguity as to whether there the reference time is referring to a future time or a past time. According to an aspect of the present invention, the fact that the low order 32 bits of the TSF timer wraps over in about 71 minutes is exploited to remove any ambiguity in the reference times contained in the Schedule Element frame. One method employs an algorithm base on distance between two reference points to determine whether the timer has wrapped around a time period, and another method uses a delay interval or a timeout to determine whether or not the TSF timer is wrapped or unwrapped. Another method includes determining whether an absolute value of X-O is less than, or greater than or equal to maximum value M/2.

摘要： Disclosed is a method and system for maintaining synchronization of the Service Period between a quality of service capable access point (QAP) and a non-AP quality of service capable station (QSTA) in a parameterized quality of service (QoS) IEEE 802.11e wireless local area network (WLAN). A problem with loss of synchronization between QAP and non-AP QSTAs can occur on downlink for parameterized QoS if the acknowledgement (ACK) frame for the last downlink frame in the Service Period is not received by the QAP because the non-AP QSTA goes to sleep too soon.

摘要： In order that media access slots MAS are allocated based on minimum latency requirements of, for example, not less than 4 ms, or on a medium utilization efficiency or power consumption requirement for a minimum reservation block length, both high-efficiency and low-latency schemes (or category) need to coexist within a superframe with fair support given to both. The maximization of contiguous available MAS between low-latency and high-efficiency schemes ensures that power saving and overhead risk are minimized without compromising the support for low-latency applications.

摘要： The application describes a method to merge two wireless networks in which each terminal gets a beacon slot within the beacon period. In order to merge two networks, the beacon slots have to be time-coordinated such that the beacon slots of the first network are completed before the beacon slots of the second network begin. The method includes transmitting a beacon frame having a beacon period switch information element which instructs the neighboring terminals in the first network of the need to merge, provides clock synchronization information; provides the time of the merge; and informs the neighboring terminals which beacon slot to occupy in the beacon period of the merged network. In order to deal with hidden terminals, the information needs to be forwarded terminal-to-terminal within each network.

摘要： In a distributed Mac protocol having a slotted superframe (102) comprising at least one slotted beacon period (104) followed by a data transfer period (103), a system and method is provided for creating and maintaining several beacon periods (104) at different positions in the superframe (102). When joining the network (300) a device (301) either joins an existing beacon period (104) or creates a new beacon period (104) at a position in the superframe (102) that does not overlap with beacon periods (104) or reservation periods. Beacon periods (104) mutually protect each other by devices (301) announcing the neighboring beacon periods in their beacons.

摘要： A system and method is provided for incorporating host-device communication in wireless IJSB (WUSB). A host (101) either uses a multicast Distributed Reservation Protocol (DRP) frame on behalf of connected devices (102) to reserve wireless channel resources, a unicast DRP frame or Enhanced Distributed Channel Access (EDCA) with a Poll Frame. In the case of a unicast DRP frame the number of unicast frames sent for reservation depends on the number of connected devices (102).
