    Abstract: The present disclosure presents methods and apparatuses for improved wireless node transmission of advertising beacons based on, for example, the presence of sufficient wireless node resource availability and one or more user equipment (UE) wakeup schedules. For example, the present disclosure describes example methods of advertising beacon transmission by a wireless node, which may include determining that a resource availability opportunity exists for supporting a UE at the wireless node. In another aspect, methods may include tuning to a non-serving channel based on determining that the resource availability opportunity exists. According to such example methods, the non-serving channel may be different from a serving channel of the wireless node. Furthermore, the example methods may include transmitting an advertising beacon on the non-serving channel. Upon successful receipt of the advertising beacon, the UE may scan for the serving channel of the wireless node for subsequent wireless network access.

    Abstract: A method includes determining, at a first transmitter, whether to permit reuse of a first transmit opportunity (TXOP) associated with a message. The method further includes sending a portion of the message from the first transmitter to a first receiver. The portion of the message indicates whether reuse, by a reuse transmitter, of the first TXOP is permitted. When reuse of the first TXOP is permitted, the reuse transmitter is permitted to send a second message while the first transmitter sends a second portion of the message to the first receiver during the first TXOP.

    Abstract: Systems, methods, and devices for concurrently allowing station-to-station transmissions and access point-to-station transmissions are described herein. In some aspects, a method comprises receiving, from a first device, a peer request to send message requesting a first time for transmissions with a second device. The method further comprises reserving the first time for transmissions between the first device and the second device. The method further comprises transmitting a coordination message to the first device and the second device. The coordination message may indicate that the first time is reserved for transmissions between the first device and the second device. The method further comprises transmitting a first data packet to a third device during a time other than the first time. The first device may transmit a second data packet to the second device during the first time.
