Abstract: Methods and apparatuses for wireless communications are disclosed. In one aspect, an apparatus for wireless communications includes a receiver configured to wirelessly receive a message comprising a time for the apparatus to wake up and instructions to execute an action in response to receiving a paging frame from a wireless communication device. The receiver is further configured to receive the paging frame from the wireless communication device. The apparatus further includes a processor configured to execute the action in response to receiving the paging frame. In one implementation, receiving the paging frame comprises comparing an address of the paging frame with an address of the apparatus. The action may include one or more of sending a power save poll frame, waiting for packet reception, receiving the beacon, and receiving the delivery traffic indication message beacon.

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.
