    摘要: Methods and apparatus for network setup in wide channel WLANs are provided. Techniques for co-existence of 20 MHz and 40 MHz networks (e.g., as defined by IEEE 802.11n) may be extended to 80 MHz and 160 MHz networks. For example, a primary channel of an existing network may be designated as the primary channel of a new network. Further, a primary channel of the existing network may not be used as a secondary channel in the new network. Intolerance operation between networks may include a first network releasing one or more channels in response to an intolerance indication received from a second network. Furthermore, in response to the intolerance indication from the second network, the first network may utilize one or more channels for communicating in the first network using a first set of access parameters. The access parameters may depend on the intolerance indication.

    摘要: One aspect of the disclosure provides a method for wireless communication by a station or wireless device. The method includes waking from a sleep state. Further, the method includes determining an availability of a transmission medium. In addition, in response to determining that the transmission medium is not available, the method can include determining a sleep time period, entering a second sleep state based on the sleep time period, and freezing a backoff counter for the duration of the second sleep state.

    摘要: A communication device for transmitting beamformed signals using implicit channel sounding is described. The communication device includes a processor and instructions stored in memory. The communication device receives one or more sounding signals and computes a channel estimate based on the one or more sounding signals. Frequency offset compensation is applied to the channel estimate by the communication device. The communication device also computes a precoding matrix based on the channel estimate and transmits a beamformed signal using the precoding matrix. Another communication device for receiving beamformed signals using explicit channel sounding is also described. The communication device includes a processor and instructions stored in memory. The communication device receives one or more sounding signals, computes a channel estimate based on the one or more sounding signals and applies amplitude compensation to the channel estimate. The communication device also sends estimated channel data and receives a beamformed signal.

    摘要: Transmission parameters are determined for communication between apparatuses. These transmission parameters may specify, for example, a number of spatial streams, a bandwidth, and a transmission rate. Based on the determined parameters, a table of a set of tables comprising transmission parameters is identified and an index from the table is determined. Rate information is then sent in a frame from one of the apparatuses to the other. The rate information comprises several fields indicative of the index, the number of spatial streams, and bandwidth. The apparatus that receives the rate information may then use this information to identify the table and obtain transmission parameters from the table.

    摘要: Certain aspects of the present disclosure provide techniques and apparatus for managing group identifiers (IDs) in multiuser multiple-input multiple-output (MU-MIMO) schemes to ensure that the group ID maps to the same assigned spatial stream position for a particular station (STA), for either Direct Link Service (DLS) or downlink (DL) MU-MIMO transmissions. One example method generally includes transmitting, from a first apparatus to a second apparatus, a message requesting assignment of a group ID identifying a group of apparatuses for receiving MU transmissions; and receiving, from the second apparatus, an indication of the assigned group ID, such that spatial stream assignments for the group of apparatuses are the same between the first and second apparatuses, the spatial stream assignments corresponding to the assigned group ID.
