    Abstract: A method of data communication for a communication device in a wireless ad hoc network is disclosed. The method comprises receiving a service publish message and a service subscribe message from a first communication device of a first service cluster and a second communication device of a second service cluster respectively, wherein the second communication device subscribes a service from the first communication device, and establishing a third service cluster including the first communication device and the second communication device, wherein a schedule of the third service cluster for the communication device, the first and second communication devices of the third service cluster to wake up for data transmission and reception is determined by the communication device or coordinated by the communication device, the first and the second communication devices.

    Abstract: A method for transiting basic service sets (BSSs) in a wireless communications system is provided. A wireless station first detects an integrity of a real-time flow from an access point in a first BSS. The wireless station then sends a request frame to the access point. The request frame comprises a communication condition of the wireless station. The access point responds with information of a plurality of APs and a set of parameters that used to select the APs. The wireless station then determines which AP to be associated according to the information of the plurality of APs and the communication quality of the wireless station.

    Abstract: A management device accepts a first communications device to join a wireless communications network managed by the management device. The management device registers a service provided by the first communications device. The service is available in accordance with a set of service parameters. The set of service parameters include a schedule of availability. The set of service parameters include at least one parameter selected from the group consisting of a set of one or more starting times, a set of one or more service intervals, a set of one or more service periods, a set of one or more physical media, a set of one or more device identifiers, a set of one or more data sequence identifiers, and at least one medium access mode within the service interval.

    Abstract: A unified channel contention scheme is proposed such that spatial reuse can be enabled by a wireless station (STA) when a basic service set (BSS) color of a received signal cannot be resolved. If the detected frame is an intra-BSS frame, then the STA should not contend the channel for the PPDU duration. If the detected frame is an inter-BSS frame, then the STA uses OBSS Packet Detection (OBSS-PD) level as the CCA level for channel contention. Furthermore, when BSS color cannot be resolved, channel contention schemes for WiFi signal and non-WiFi signal are differentiated. If the received signal is detected as WiFi signal, then the STA uses WiFi-SIG Detection (WD) level as the CCA level for channel contention. If the received signal is detected as non-WiFi signal, then the STA uses Non-WiFi-SIG Detection (NWD) level as the CCA level for channel contention.
