    Abstract: Wireless communication in a wireless network comprises a wireless station obtaining a transmission opportunity period (TXOP) for communicating with an access point (AP) over a wireless communication channel. The wireless station sends an announcement to the AP to share the transmission opportunity period with at least another wireless station, as a multi-user transmission opportunity period for simultaneously transmitting data from said wireless stations to the AP on multiple uplink (UL) spatial streams over the wireless channel. UL TXOP transmission information is communicated based on one or more indications included in a quality of service (QoS) data frame and a frame header.

    Abstract: In one aspect of the present invention, a method for managing communications in a sensor network will be described. A coordinator device receives charging interval data from an energy harvesting sensor device. A sleeping interval for the sensor device is determined. A beacon frame is transmitted from the coordinator device to one more sensor devices in a network. The timing of the transmission is based at least in part on the sleeping interval data. The beacon frame may contain requests, commands or other data designated specifically for the sensor device. Various other aspects of the invention relate to the sensor device, the coordinator device and/or their operations.
