Abstract: A transmitting wireless device provides channel spatial reuse information to a receiving wireless device for the receiving wireless device to make a determination of how to contend the medium for spatial reuse transmission, when to transmit and what transmissions parameters to use for the transmission in the spatial reuse. A timer is designated to track the remaining time for inter-ESS and/or intra-ESS spatial reuse. The spatial reuse information may include fields indicative of color code identifying BSS, transmission power used, signal to noise ratio headroom available and so on. With the spatial reuse information, the wireless device can calculate the target transmit power for initiating spatial reuse transmission without interrupting the on-going transmission, perform EDCA in spatial reuse condition to assess the channel status for contending the medium over the on-going transmission(s), tracking the spatial reuse duration and initiate a new spatial reuse transmission over the on-going transmission without interruption.

Abstract: Application mobility is a unique feature of the edge computing to support relocation of application instance across edge computing hosts or between edge computing host and cloud computing over underlying mobile network. With the active-standby mode application instance implementation with support of L2 networks, the application mobility could achieve the service continuity with low latency switching time. An application mobility mechanism can be implemented in the data plane of edge computing host under the control of edge computing platform and management. It can be also implemented in L2 switching function of the User Plane Function in 5G networks.

Abstract: A power saving station integrates a low power consumption wake-up receiver with wideband wireless of main radio. The low power wake-up receiver of power saving station receives a wake-up request signal sent from the wireless network and wakes up the main radio of the station to communicate with the wireless network over wideband frequency channel. The wake-up request signal is transmitted over a narrow band frequency channel and can be addressed to a single station or multiple of stations via OFDMA in wideband channel.
