Abstract: Described herein are apparatuses, methods, and computer program products for low latency STAs to select the backoff counters in such a way that can reduce collisions during the P-EDCA contention. An adaptive contention technique is employed that reduces the probability of collisions, while maintaining fair access to the channel and limiting overhead. Each low latency STA may initially obtain a distinct probability distribution for the backoff counter selection with a contention slot selected based on the probability distribution. The selected slot may be transformed, such as by being permutated, to produce the backoff counter to be used by a low latency STAs.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and medium for enablement of a non-primary channel access (NPCA) scheme and a coordinated spatial reuse (C-SR) scheme. In an aspect, a first device detects an overlapping basic service set (OBSS) transmission of a second device, the OBSS transmission of the second device utilizes a frequency resource substantially overlapping with a primary channel of the first device. The first device determines to enable a NPCA scheme or a coordinated spatial reuse (C-SR) scheme based on detection of the OBSS transmission of the second device, wherein the first device switches to use a NPCA primary channel instead of the primary channel under the NPCA scheme, and the first device reduces a transmitting power under the C-SR scheme. By implementing embodiments of the present disclosure, rules for not enabling the NPCA scheme and the C-SR scheme at the same time are defined.

Abstract: A method, apparatus and computer program product are provided from the perspective of a station, an access point and an intermediate device in order to provide a channel state information (CSI) report from a station to an access point with which this station is unassociated while protecting the privacy of the CSI report. Even though the CSI report is to be transmitted from a station to an access point with which the station is unassociated, the CSI report is transmitted via one or more secure connection links, such as by being encrypted while being transmitted via the one or more connection links. The CSI report is therefore not exposed via an unsecured connection link to a third party, thereby protecting the privacy of the CSI report.

Abstract: A signal constellation for a multiple input/multiple output (MIMO) communication system when channel knowledge at the receiver is imperfect includes at least two (n?1)-dimensional sub-constellations of points that together form an n-dimensional constellation, the number n representing real dimensions and n=2M where M is the number of transmit antennas. The n-dimensional spherical constellation may define a single sphere or a plurality of concentric subset spheres, and points between subsets are separated by a Kullback-Leibler distance rather than a Euclidian distance. Each sphere has sub-constellations that preferably are arranged in symmetric pairs that define equal numbers of points that lie in parallel planes, to allow recursive construction that minimizes computational complexity. An appropriate constellation may be chosen by ceasing a search once the optimum minimum distance stops increasing as a number of the concentric levels increases.
