Abstract:
Systems, methods, and devices for communicating short control frames are described herein. In some aspects, a method of wireless communication includes generating a control frame comprising a contention free end (CF-end) frame, the CF-end frame comprising a physical layer preamble having a type field, the type field including an indicator indicating the CF-end frame is a null data packet (NDP). The method further includes transmitting the control frame.
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:
Certain aspects of the present disclosure provide techniques for selecting a modulation class, coding rate, and/or modulation and coding (MCS) scheme for transmission of a response message corresponding to a received message. Different rules may be applied for selecting the MCS scheme depending on whether or not the frame eliciting the response was transmitted as high throughput (HT) or very high throughput (VHT) transmission.
Abstract:
Methods and apparatus for wireless communication are disclosed. In one aspect, a method includes generating, by an apparatus, a message indicating a start time of a window during which one or more devices are permitted to communicate with the apparatus, the start time being based on an absolute time reference; and transmitting, by the apparatus, the generated message. In some aspects, the absolute time reference is based on a target beacon transmit time (TBTT). In some aspects, the absolute time reference is based on a timing synchronization function (TSF).
Abstract:
Systems and methods for wireless communication are disclosed. In one aspect an access point includes a processor configured to generate a message identifying a time period in which the access point will enter a power save mode and ignore a packet sent from any wireless station, and a transmitter connected to the processor and configured to transmit the message to one or more wireless stations associated with the access point.
Abstract:
IEEE 802.11 power saving mode (PSM) defines two different power modes under which stations operate: active mode and power save (PS) mode. This disclosure introduces devices, methods, and systems to implement an additional power save with ultra low power (PS-ULP) mode that further reduces power consumption. In one aspect, a method of communicating a power management mode of a station on a wireless network is disclosed. The method includes transmitting by a station a first message on the wireless network, the first message indicating one of at least three power management modes, wherein the indication is communicated in a power management portion of a frame control field of a media access control header. The power management portion comprises more than one bit; and operating the station in a power management state in accordance with the indicated power management mode.
Abstract:
Systems, methods, and devices for wireless communication. In one aspect an apparatus for wirelessly communicating with a wireless station is provided. The apparatus comprises a first transceiver configured to receive a backoff signal from the wireless station during a first time period, the backoff signal configured to indicate a second time period. The apparatus further comprises a processor operationally coupled to the first transceiver and configured to refrain the first transceiver from transmitting a wireless signal during the second time period.
Abstract:
Systems, methods, and devices for communicating frames having a plurality of types are described herein. In some aspects, the frames include a compressed frame, such as a compressed management frame or a compressed control frame. In some aspects, a method of communicating in a wireless network includes generating a control frame including an identifier, the identifier comprising a portion of a frame check sequence and a service field of a frame that elicited the control frame. The method further includes transmitting the control frame.
Abstract:
This disclosure describes systems, methods, and devices for paging message enhancement, for example, by allowing packets to accumulate in an access point before sending them to a station. In some implementations, a station may not have an immediate use for a packet waiting in an access point's buffer. The station may save energy and reduce medium occupancy by allowing packets to accumulate at the access point and then receiving the accumulated packets in accordance with certain criteria. Such criteria for accumulation may be based on a Quality of Service (QoS) category, the station address, or the station type. The station may set accumulation parameters, such as a maximum occupied buffer size or a maximum time for which a station's packets are delayed for accumulation.
Abstract:
A method includes in response to receiving a modified enhanced distributed channel access (EDCA) parameter set IE at a station, determining a value of an EDCA parameter based on a delta value in the modified EDCA parameter set IE and based on a base value of the EDCA parameter.
