Abstract: A method can include wireless device operations, including receiving a trigger communication that identifies available random access resource units (RA RUs), the RA RUs being portions of transmission channel for a wireless system. In response to a back-off value and a number of available RA RUs, selecting or not selecting one RA RU as a transmission RA RU. In response to not selecting a transmission RA RU, monitoring for wireless responses following the trigger communication to determine unselected RA RUs, designating one unselected RA RUs as an alternate RA RU; and transmitting uplink data on the alternate RA RU. The unselected RA RUs comprise any RA RUs that remain after other wireless devices have selected RA RUs in response to the trigger communication. Corresponding devices and systems are also disclosed.

Abstract: A passive entry, passive start (PEPS) application is described, wherein a number of sensors are configured with wireless communication protocol information for wireless communication between a master device and a BLE hub. The sensors eavesdrop signals from the master device to the BLE hub while not in operative communication with the master device. Eavesdropped signals are processed to determine and calculate position-related information, such as phase and magnitude of the wireless signals received at multiple antennas of the sensors, angle-of-arrival (AoA), and distance or position of the master device relative to the sensors, individually or as a system. Power management techniques for a PEPS system are also described.

Abstract: According to embodiments, methods, devices and systems can include monitoring all of a first channel for a first monitoring period. After the first monitoring period, monitoring at least one narrow band for at least a first narrow band signal. In response to detecting the first narrow band signal, establishing a network connection over the narrow band, wherein the at least one narrow band has a frequency range less than one half that of the first channel.

Abstract: A wireless communication device and method for operating the same for mitigating interference in a wireless communication network are provided. Generally, the method includes sensing with the wireless communication device pulses of electromagnetic radiation recurring within a band of frequencies used by the device for communication of signals, identifying the pulses as interference, and determining a number of frequencies of the interference within the band of frequencies used by the wireless communication device. Next, a sensitivity of the wireless communication device is reduced upon sensing one of the pulses and repeated at a frequency corresponding to the frequency of the interference. Thus, a spectrum of electromagnetic radiation around the wireless communication device is perceived by the device as free of interference, enabling it to transmit and/or receive more often. Other embodiments are also disclosed.

Abstract: According to embodiments, methods, devices and systems can include generating packet data for a narrow band packet. Transmitting first preamble data across a first channel followed by the narrow band packet with a second preamble across at least one resource unit (RU). The RU can have a smaller bandwidth than the first channel and occupy a portion of the first channel. The first preamble can be configured to enable detection of a packet transmitted in the first channel, and the second preamble is configured to enable detection of a packet transmitted in the RU without the first preamble.
