Abstract:
In a power save scheme, signaling and information transfers are scheduled to increase the amount of time a device in a wireless system can operate in power save mode. Multiple periods of time are allocated for signaling and for information transfer during a beacon interval. Control signaling during a signaling block indicates whether a given device should be awake for an information transfer during a subsequent information transfer period during the beacon interval. Thus, based on the indication, the device determines whether to be awake or asleep during the information transfer period.

Abstract:
Systems, methods, and devices for communicating in a wireless network are provided. In one aspect, a method for wireless communication is provided. The method includes inserting an indication of a scrambling sequence into a signal field of a first data unit. The signal field occurs before a service field in the first data unit. The method includes scrambling at least a portion of the first data unit based at least on the inserted indication of the scrambling sequence in the signal field of the first data unit. The method includes transmitting the first data unit. The signal field is transmitted at a first data rate and the service field is transmitted at a second data rate greater than the first data rate. The indication of the scrambling sequence comprises either a scrambler seed or one or more parameters indicative of the scrambling sequence.
Abstract:
A method of enabling data to be relayed between an access point (AP) and a target station (STA). The AP identifies the target STA based at least in part on a medium usage efficiency of the target STA. The AP further sends a relay selection trigger to the target STA to cause the target STA to broadcast a relay selection request to a set of candidate STAs. The relay selection request includes a set of metrics pertaining to a direct link between the AP and the target STA. The AP then receives one or more relay selection responses from one or more candidate STAs in the set of candidate STAs based at least in part on the set of metrics and selects a relay STA from the set of candidate STAs based at least in part on the one or more relay selection responses.

Systems, methods, and devices for wireless communication are described herein. In some aspects, a method of wireless communication includes transmitting a first message for establishing a reservation of the communication medium utilizing a first combination of transmission characteristics such that the first message is readable by a plurality of wireless devices. The method may further include subsequently transmitting a plurality of messages for clearing the reservation of the communication medium, each of the plurality of messages utilizing a different combination of transmission characteristics than the first combination such that each of the plurality of messages is readable by a different subset of the plurality of wireless devices, thereby sequentially clearing access to at least one communication channel of the communication medium for each different subset of the plurality of wireless devices.
Abstract:
Methods, systems, and devices are described for improve network performance, such as throughput and PER, by allowing nodes to adjust energy detection (ED) threshold levels. For example, a method for Wi-Fi wireless communication includes determining, by a first node, an ED threshold level for a second node of a wireless network based at least in part on a metric for the first node. The method may also include signaling, from the first node to the second node, an ED level set element that indicates the determined ED threshold level. In another example, a method includes signaling, by a first node, an ED level adjustment capability of the first node to one or more nodes in a wireless network.
Abstract:
Systems, methods, and devices for wireless communication are provided. In an embodiment, a method of wireless communication includes receiving, at an access point, a probe request, decoding the probe request to determine shared wireless device state information, storing the shared wireless device state information for at least a timeout period, transmitting a probe response indicating the timeout period; and receiving an association request omitting the wireless device state information within the timeout period.
Abstract:
Methods, devices, and computer program products for transmitting and receiving discovery and paging messages are described herein. In one aspect, an apparatus operable in a wireless communication system includes a receiver and transmitter. The receiver receives a registration packet from a first device. The registration packet indicates interest in a service provided by another device in a wireless communications network. The receiver further receives a discovery packet from a second device during a first discovery interval of a plurality of discovery intervals. The discovery packet advertises a service provided by the second device, and the plurality of discovery intervals include recurring time intervals when a plurality of devices are configured to transmit and receive discovery packets in the wireless communications network. The transmitter transmits a notification packet configured to enable the first device and the second device to communicate directly.
Abstract:
A user terminal for multiple-user wireless communication is provided, comprising a transmit buffer configured to store uplink data for transmission. The user terminal comprises a processor configured to generate a request to transmit frame in response to uplink data being present in the transmit buffer, and initiate a transmit timer for determining when to transmit the request to transmit frame. The user terminal comprises a transmitter configured to transmit the request to transmit frame when the transmit timer expires or when the uplink data present in the transmit buffer exceeds a threshold amount. The user terminal comprises a receiver configured to receive a clear to transmit frame from an access point based on the transmitted request to transmit frame. The transmitter is further configured to transmit the uplink data present in the transmit buffer, concurrently with at least one other user terminal transmitting uplink data, to the access point at a specified time based on receiving the clear to transmit frame addressed to the user terminal.
