    Abstract: Systems and methods for low overhead paging in a wireless communications network are described herein. In some aspects, an apparatus for wireless communication includes a receiver and a processor. The receiver receives a request from a first device. The request indicates a first period of a plurality of periods corresponding to a periodicity for transmitting paging messages. The processor assigns the first device to a group scheduled to receive paging messages at most every first period based on the request and determines a start time for transmitting paging messages to the first device based on schedules for transmitting paging messages to a plurality of other devices. In other aspects, an apparatus for wireless communication includes a processor and memory. The processor derives an information sub-unit from an information unit associated with a paging message, compresses the information sub-unit, and generates a second information unit associated with the method of compression.

    IPC: H04W56/00

    Abstract: Indication of globally synchronous communications mode is disclosed. A first node may detect an indication signal transmitted by a second node at a synchronization boundary of a shared communication channel. The indication signal is configured to identify a first transmission synchronization mode of the second node. The first node may then adjust its communications configuration in response to the indication signal. In making such adjustments, the first node may either contend for communications on the shared communication channel using the first transmission synchronization mode or refrain from attempting the communications on the shared communication channel using a second transmission synchronization mode.

    Abstract: Technology-specific listen before talk (LBT) parameter adjustments are disclosed for common energy detection (ED) thresholds. Some of the technologies sharing access to the same shared communication spectrum include additional access deferral procedures. Such technologies may be configured with additional compensating features to increase the likelihood of fairness in spectrum access across all technologies sharing a common ED threshold. Such additional compensating features may include a reduced contention window size relative to the technologies that do not include such additional access deferral procedures, increased maximum channel occupancy times (COTs) for longer transmissions, and the like. Each such additional compensating feature may be available under different circumstances, such as always available or available in response to the node activating one of the additional access deferral procedures. Additionally, such additional compensating features may, once initiated, be active and available for a predetermined period of time.

    Abstract: This disclosure provides systems, methods and apparatuses for coordinating access to a shared wireless medium among multiple master devices operating on the same frequency band. In some implementations, master devices may contend for access to the shared medium during a medium reservation window (MRW). During the MRW, master devices may advertise their intent to reserve at least a portion of the shared medium for one or more timeslots within a subsequent medium utilization period. The reservation messages may be broadcast to other master devices in the vicinity to prevent other master devices from accessing the wireless medium during a reserved timeslot. In some implementations, the owner of a timeslot may share at least a portion of its timeslot with other master devices. For example, the timeslot owner may enable other master devices to utilize an unused portion of the wireless medium, such as unused channels, spatial streams, or time.

    Abstract: Various aspects of a communication device for supporting wireless communication for a plurality of stations associated with the communication device are provided. The communication device includes a transceiver configured to receive a request for a wakeup schedule to support direct communications between a first one of the stations and a second one of the stations. In an aspect, the wakeup schedule request may be included in a beacon frame or a probe frame. The communication device also includes a processing system coupled to the transceiver and configured to determine the wakeup schedule for the direct communications based at least in part on the request for the wakeup schedule. In an aspect, the processing system may be configured to determine the wakeup schedule based on one or more parameters included in the wakeup schedule request. In an aspect, the wakeup schedule may include one or more wakeup intervals.

    Abstract: Methods, systems, and devices for wireless communications are described. A station (STA) may receive a wakeup radio (WUR) frame for the STA at a WUR. The STA may identify, from a number of packet number generation schemes, a scheme that the STA is to use to construct a packet number for the WUR frame. Following the scheme identification, the STA may generate a packet number for the received WUR frame using the identified scheme and determine whether to discard the WUR frame based on the generated packet number. In some implementations, the STA may determine whether the STA is to use, for communications received from an access point (AP) to the WUR, a same key or a second key, the second key being different from a first key used by the STA to receive protected communications from the AP to a primary radio of the STA.
