Abstract:
Methods and apparatus for adjusting transmission power in wireless networks are provided. One aspect of the disclosure provides an apparatus for wireless communication. The apparatus includes a processing system configured to receive a message instructing each of multiple devices to transmit a packet at least partially concurrently with each transmission of the other multiple devices. The processing system is further configured to generate the packet. The packet includes an indicator having a value greater than a time associated with a transmission of the packet. An interface is configured to provide the packet for transmission.
Abstract:
A method of wirelessly communicating a packet including a first portion for transmission over a channel of a first transmission type and a second portion for transmission over a channel of a second transmission type. In one aspect, the method includes generating a first signal field indicative of a channel assignment to the first transmission type. The method further includes generating a second signal field indicative of a channel assignment to the second transmission type. The method further includes transmitting, at a same time, the first signal field duplicated over each channel of the first transmission type, and the second signal field duplicated over each channel of the second transmission type.
Abstract:
Systems, methods, and devices detect and managing the presence of bursty interference on a wireless communication system. A method of detecting the presence of bursty interference on a wireless network includes receiving, at a wireless device, a message from a transmitting device. The method further includes determining whether the message includes errors caused by bursty interference. The method further includes suspending a channel tracking when bursty interference is detected. The method may further include reporting bursty interference to the transmitting device when bursty interference is detected.
Abstract:
Methods and apparatus methods and apparatus for providing wireless messages according to various tone plans. One aspect of the disclosure provides an apparatus including a processing system. The processing system is configured to select from one of a 256-, 512-, 1024-, and 2048-tone plan for wireless communication of a message. The processing system is further configured to, upon selecting the 256-tone plan, provide the message for transmission over a 20 MHz bandwidth. The processing system is further configured to, upon selecting the 512-tone plan, provide the message for transmission over a 40 MHz bandwidth. The processing system is further configured to, upon selecting the 1024-tone plan, provide the message for transmission over a 80 MHz bandwidth. The processing system is further configured to, upon selecting the 2048-tone plan, provide the message for transmission over a 160 MHz bandwidth.
Abstract:
A method of determining a position location of an asset tag within an indoor position location system includes filtering a history of locations of an asset tag within the indoor position location system. Such a method further includes computing, based on the history, a likelihood that the asset tag is in a predetermined room of the indoor position location system.
Abstract:
A method includes generating a data packet at an access point. The data packet is to be communicated using a waveform that includes a first set of tones that is allocated to a first destination device and a second set of tones that is allocated to a second destination device. The first set of tones is non-overlapping with respect to the second set of tones, and each tone of the first set of tones and each tone of the second set of tones is an orthogonal frequency-division multiple access (OFDMA) tone. The method also includes transmitting the data packet to the first destination device via an institute of electrical and electronics engineers (IEEE) 802.11 wireless network and transmitting the data packet to the second destination device via the IEEE 802.11 wireless network.
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 a plurality of scrambler seeds into a data unit comprising a plurality of data portions, each scrambler seed associated with a respective data portion of the plurality of data portions. The method includes scrambling each data portion at least in part based on the associated scrambler seed. The method includes transmitting the data unit. The data portions may comprise code words or at least one media access control protocol data unit. The scrambler seed may be inserted in reserved bits of the delimiter field. The scrambler seed may be inserted in a delimiter signature field of the delimiter field.
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:
One aspect disclosed is a method in a wireless communications system including a first primary channel having a first frequency spectrum bandwidth and a second primary channel having a second frequency spectrum bandwidth, wherein the second frequency spectrum bandwidth includes the first frequency spectrum bandwidth. The method includes performing a first and a second back-off procedure at least partially in parallel, the first back-off procedure based on whether the first primary channel is idle, and the second back-off procedure based on whether the second primary channel is idle, and transmitting a wireless message based on whether the first or the second back-off procedure completes first.
