20140341100 | ACCESS POINT-AIDED COEXISTENCE/CONCURRENCY AT MOBILE DEVICES - Methods, systems, and devices are described that enable a WLAN access point (AP) to schedule packet transmissions to (or from) a mobile device taking into consideration the schedule of various other coexisting transmission/reception (Tx/Rx) activities on the mobile device. Various approaches may increase throughput at the mobile device. Various approaches also may benefit other stations associated with the same AP. | 11-20-2014 |
20150036573 | WLAN-CAPABLE REMOTE CONTROL DEVICE - Operations for a WLAN-capable remote control device and a controlled device are disclosed. A first network device (e.g., remote control) may receive a user input for controlling operation of a second network device (e.g., controlled device) of a communication network. The first network device may transition to an active operating state in response to receiving the user input. The first network device may transmit the first user input to the second network device. The first network device may exit the active operating state in response to successfully transmitting the first user input to the second network device. | 02-05-2015 |
20150303741 | WIRELESS ENERGY TRANSMISSION - An energy transmitting device (e.g., access point) can transmit an energy signal to a wireless device. The wireless device can obtain energy from the energy signal. The energy signal may be transmitted via an unused frequency sub-range of a frequency range associated with a communication signal. In one embodiment, the energy signal may occupy a frequency sub-range in unused frequencies of an orthogonal frequency division multiplexed (OFDM) signal transmission. The energy signal may be transmitted in a manner that coexists without interfering with traditional communication signals. Various control/configuration settings may be used to enable or disable the energy signal, for example, based on capability of a wireless device to harvest energy from the energy signal or in accordance with a schedule. | 10-22-2015 |
20160029229 | SYSTEMS AND METHODS FOR STATION SIGNALING IMPAIRED RECEIVER OPERATION - Methods, devices, and computer program products for station signaling impaired receiver operation are disclosed. One aspect of the present disclosure relates to a method of communication in a wireless communication network including determining an impairment causing a packet drop at a first wireless device, the impairment capable of causing the packet drop(s) based on a condition other than poor link conditions. The method further includes generating an indication of the impairment, the indication comprising an identification of the first wireless device and information about the impairment, and transmitting the indication to a second device configured to transmit packets to the wireless device. Another method of communication disclosed comprises receiving an indication that an impairment is capable of inhibiting reception of packets at another wireless device based on a condition other than poor link conditions, and adjusting a behavior of the wireless device that received the indication, based on the indication. | 01-28-2016 |
20160036637 | SIGNALING CHANGE IN LINK CONFIGURATION - A method, an apparatus, and a computer program product for wireless communication are provided. In one aspect, the apparatus, being a first wireless device, establishes a session with a second wireless device based on a first set of link parameters and transmits, to the second wireless device, information regarding a second set of link parameters for use by the second wireless device for subsequent communication during the session. In another aspect, the apparatus establishes a session with a second wireless device based on a first set of link parameters, receives, from the second wireless device, information regarding a second set of link parameters, and communicates with the second wireless device based on the information regarding the second set of link parameters. | 02-04-2016 |
20160037558 | ESTIMATING WIRELESS CAPACITY - A system and method are disclosed that may provide an accurate estimate of an AP's available medium share. The AP may perform a plurality medium access contention operations to determine a duration of a transmit opportunity and a queue service interval for each of a plurality of access categories. The AP may also determine a queue service interval for a number of packet queues associated with each of the access categories. The AP may use timing information derived from the medium access contention operations to estimate a portion of the medium share available on a per-access category and/or per-user basis. The timing information may include the transmit opportunity durations and queue service intervals for the access categories, the queue service intervals for the individual packet queues, and/or values indicative of the AP's PHY rate and medium utilization. | 02-04-2016 |
20160037559 | METHOD AND SYSTEM FOR ESTIMATING AVAILABLE CAPACITY OF AN ACCESS POINT - A system and method are disclosed that may provide an accurate estimate of an AP's available capacity. The AP may simulate medium access contention operations using actual packets being transmitted from the AP to associated STAs and virtual packets indicative of traffic that would be transmitted to a new STA that is not currently associated with AP. The AP may determine a transmission schedule for the actual packets and virtual packets based on the simulated medium access contention operations, and then determine what portion of the available capacity is allocated to the virtual packets based, at least in part, on the transmission schedule. | 02-04-2016 |
20160057605 | ULTRA LOW-POWER PAGING FRAMES FOR WAKE-UP AND DISCOVERY - Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to ultra low-power paging frames for wake up and discovery. One example apparatus for wireless communications generally includes at least one interface configured to receive via a first radio and a second radio, wherein the at least one interface receives a paging frame from another apparatus via the second radio while the first radio is in a first power state that is lower than a second power state of the second radio; and a processing system configured to take one or more actions based on a command field included in the paging frame. | 02-25-2016 |
20160057703 | SECURE WIRELESS WAKE-UP COMPANION - Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to ultra low power paging frames for wake up and discovery. One example apparatus for wireless communications generally includes at least one interface configured to obtain a frame via a first radio and a second radio, wherein the interface receives a frame from another apparatus via the second radio while the first radio is in a first power state; and a processing system configured to take one or more actions based on a command field included in the frame. A second example apparatus for wireless communications generally includes at least one interface configured to obtain a frame via a first radio and a second radio, wherein the interface receives a frame from another apparatus via the second radio while the first radio is in a first power state; and a processing system configured to take one or more actions based on whether or not an authentication code included in the frame matches a local authentication code. | 02-25-2016 |
