Abstract: This disclosure provides wireless nodes, methods, apparatus, means plus and computer-readable mediums for randomly determining detection thresholds, such as energy detection (ED) thresholds, and then using such randomly determined thresholds to determine whether a channel is busy or idle when performing clear channel access (CCA). In some implementations, a new random detection threshold may be determined at a start of each backoff or each subsequent backoff slot. In some other implementations, a range of energy from which the detection threshold is randomly determined may depend on measurements of traffic activity, the number of MAC addresses observed or the priority of the traffic.

Abstract: This disclosure provides systems, methods, apparatus and wireless nodes as well as computer programs encoded on computer-readable mediums for providing synchronized start times of backoff windows in a given or particular physical area. In some implementations, a schedule of synchronized start times may be determined and an indication that the first schedule is active may be signaled. In some other implementations, signaling indicating a first schedule of synchronized start times is active may be detected and channel access may be performed according to the first schedule.

Abstract: An effective way for the cellular device-to-device communication and the short range communication to share a set of channels for communication is desired. The apparatus may be a user equipment (UE). The apparatus determines a priority level of each channel of a plurality of channels. The apparatus determines whether a first channel of the plurality of channels, the first channel having a highest priority level, is occupied by short range wireless communication. If the first channel is occupied by the short range wireless communication, the apparatus determines availability of one or more remaining channels of the plurality of channels for a cellular device-to-device (D2D) communication, where the one or more remaining channels are different from the first channel.

Abstract: Wireless communications systems and methods related to narrow beam-based channel access for communications in a wireless communication network operating over an unlicensed spectrum are provided. A first wireless communication device receives, from a second wireless communication device, one or more signals associated with a beam parameter. The first wireless communication device determines, at each of a plurality of locations, a signal measurement for at least one received signal of the one or more received signals. The first wireless communication device determines, based at least in part on an p-th percentile signal measurement and a q-th percentile signal measurement of the signal measurements at the plurality of locations, whether the second wireless communication device satisfies an interference condition.
