  • Patent number: 10231179
    Abstract: Systems and methods for wireless communications are disclosed. More particularly, aspects generally relate to an apparatus for wireless communications. The apparatus generally includes an interface for communicating with a plurality of wireless nodes via a plurality of antennas, and a processing system configured to determine a power state of each of the plurality of wireless nodes, and change from a first antenna mode used for communicating with the wireless nodes using a first number of spatial streams to a second antenna mode used for communicating with the wireless nodes using a second number of spatial streams, based on the determined power states of the wireless nodes.

  • Patent number: 10051558
    Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) transmits instructions to quiet a dynamic frequency selection (DFS) home channel for a period of time. Instructions can include a quiet information element (IE) or a clear-to-send to self (CTS2Self) frame. The AP then allocates a first dedicated RF chain to a first media access control (MAC) component and a second dedicated RF chain, separate from the first dedicated RF chain, to a second MAC component of the access point. The allocation can include reducing the number of RF chains dedicated to the first MAC component. During the time period determined by the instructions, the first dedicated RF chain scans the home DFS channel and the second dedicated RF chain scans at least one other channel (e.g., based at least in part on the time period and channel scan priority) in the same band as the DFS home channel.

  • Publication number: 20170273017
    Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may direct stations (STAs) to use a request-to-send (RTS)/clear-to-send (CTS) mode so the AP may perform power savings and off-channel operations without disrupting the communications of nearby devices. In some cases, the AP may use traffic conditions to identify a power save period and subsequently transmit an indication of an RTS/CTS mode to multiple STAs. In one example, the AP may power down at least one radio frequency (RF) chain and enter into a sleep mode. Additionally or alternatively, during the power save period the AP may receive an RTS from a STA and power up additional radio chains for MIMO communication. In some cases, the AP may identify an off-channel operations period based on traffic conditions and perform the off-channel operations after indicating the RTS/CTS mode to a set of STAs.

  • Publication number: 20060077412
    Abstract: A method for optimizing data transmission costs is disclosed. A compressibility test is performed on a number of bits within an observation interval during a data transmission. Once the length of the observation interval for a data transmission mode has been selected, the value of savings achieved during the data transmission can be determined. The value of savings is then compared to a predetermined threshold saving value set for either a compressed mode or an uncompressed mode. If the value of the savings achieved in a compressed mode is less than the predetermined threshold saving value set for the compressed mode, then the data transmission mode is switched from the compressed mode to an uncompressed mode. On the other hand, if the value of savings achieved in the uncompressed mode is greater than the predetermined threshold saving value set for the uncompressed mode, then the data transmission mode is switched from the uncompressed mode to the compressed mode.

  • Publication number: 20060045174
    Abstract: A method and apparatus for synchronizing a transmitter clock of an analog modem to a codec sampling clock within a central office are provided. The analog modem includes a transmitter, a receiver and a codec. The analog modem also includes a transmitter re-sampler and a receiver re-sampler coupled to the transmitter and the receiver, respectively. Transmitter signals provided to the codec in a transmit path of the analog modem are re-sampled. The sampling rate of the transmitter re-sampler is subsequently derived from a re-sampling period of the receiver re-sampler provided between the receiver and the codec. The transmitter clock of the analog modem is then synchronized with the codec sampling clock in the central office.

  • Publication number: 20060045173
    Abstract: A method and apparatus for improving upstream connect rates of an analog modem are provided. The analog modem includes a modem transmitter, a modem receiver, a transmitter re-sampler, a receiver re-sampler and a codec. A sampling rate converter is provided between the modem transmitter and the transmitter re-sampler. The sampling rate converter changes the input sampling rate to the transmitter re-sampler by a factor equal to the ratio of the sampling rate of analog modem codec to the symbol rate of the modem transmitter in order to avoid attenuation in the transmitter re-sampler. The transmitter clock is synchronized with the codec sampling clock in a central office. The transmitter re-sampler corrects the clock difference between the sampling clocks of modem codec and central office codec.
