Abstract: Systems, methods, and devices for communicating data in a wireless communications network are described herein. In some aspects, a station includes a first receiver and a low power circuit including a second receiver. The second receiver may be configured to consume less power than the first receiver. The second receiver receives short paging messages from another wireless device, such as an access point. The paging messages may trigger transitions of the first receiver from inactive doze or sleep states to active awake states based on Traffic Information Maps. Once in the awake state, the first receiver receives messages. This enables the first receiver to reduce the time spent awake, thereby reducing power consumption. A system and method for identifying and managing paging modes is described herein.

Abstract: An access point (AP) may prioritize the allocation of uplink resources between multiple basic service sets (BSSs). In some aspects, the AP may select one of a plurality of BSSs, may allocate one or more random resource units (RUs) to only the selected BSS, and may transmit a frame indicating the allocation of the one or more random RUs to the selected BSS. Wireless devices belonging to the selected BSS may contend for access to the random RUs allocated by the frame, and then transmit uplink data using the random RUs.

Abstract: Systems, methods, and computer readable storage media communicate with a wireless device within a dense wireless environment. In one aspect, a method includes determining whether a wireless device is subject to interference, adjusting a transmission attribute based on the determining, and transmitting a message to the wireless device based on the adjusted transmission attribute. In some aspects, adjusting a transmission attribute may include selecting one or more of time division multiplexing or frequency division multiplexing when communicating with the wireless device. In some aspects, particular time periods and/or particular frequency bands may be selected for communication with the device depending on whether the device is subject to interference.
