    摘要: Explicit feedback format within single user, multiple user, multiple access, and/or MIMO wireless communications. A beamformer provides a first communication to a beamformee, and based thereon, the beamformee may ascertain certain characteristics associated with the type and format of feedback to be provided to the beamformee via a second communication from the beamformee to the beamformer. For example, the first communication may include indication of a current operational mode, such as whether it is in accordance with single-user multiple input multiple output (SU-MIMO) or multi-user multiple-input-multiple-output (MU-MIMO). Also, the first communication may indicate a requested steering matrix's rank to be employed in accordance with subsequent beamforming by the beamformer. Also, additional information such as that pertaining to per-tone SNR values for each respective space-time stream, per-tone or per-sub-band eigen-values, the particular channel width being employed (e.g., 20, 40, 80, or 160 MHz), etc. may be included within the second communication.

    摘要: Range extension within single user, multiple user, multiple access, and/or MIMO wireless communications. A given communication device designed and implemented for operation in accordance with a given communication protocol, standard, and/or recommended practice operates in accordance with a down-clocked manner to effectuate operation in accordance with at least one other communication protocol, standard, and/or recommended practice. For example, first channelization may undergo down-clocking by a particular and desired ratio to generate a second channelization. As such, at least one portion of a physical layer (PHY) of a given communication device may be leveraged for use in at least one other or additional operational mode based upon the down-clocking employed. Sub-channel and/or channel adaptation may be made based upon any of a number of considerations (e.g., independently by one device, cooperatively by two or more devices, local and/or remote operating condition(s) [or changes thereof], etc.).

    摘要: Doppler adaptation using pilot patterns within single user, multiple user, multiple access, and/or MIMO wireless communications. Within a communication system employing orthogonal frequency division multiplexing (OFDM) signaling, pilots may be adaptively and/or selectively located at different respective sub-carrier or tone locations within different respective symbols based on one or more patterns. In some implementations, decimation may also be performed such that not necessarily all respective tone or sub-carrier locations are covered within one particular group. Multiple respective groups may be employed to cover all possible tone or sub-carrier locations with at least one pilot over a particular number of symbols. In a receiver communication device operating using such decimation, interpolation over the decimated set of tones or sub-carriers may be made to effectuate channel estimate updates.

    摘要: Preamble for use within single user, multiple user, multiple access, and/or MIMO wireless communications. A selected preamble type is employed for use in generating a signal to be transmitted from one communication device to at least one other communication device. Depending upon a desired operational mode, as few as one preamble type, or two or more preamble types may be associated with a given operational mode. When operating in accordance with a given operational mode, a preamble type is selected from available preamble types of an operational mode. A preferred implementation may include two respective preamble types such that one preamble type is used for single user (SU) operation with transmit beamforming weights applied at the beginning of the packet or for open loop SU transmissions only, while the other preamble type, having an multiple user (MU) characteristic, is used for both SU beamforming and MU operations.

    摘要: Frequency selective transmission within single user, multiple user, multiple access, and/or MIMO wireless communications. Adaptation among different respective sub-channels and/or channels is effectuated within a wireless communication system. Such a wireless communication system may include an access point (AP) and one or more wireless stations (STAs). The respective channelization employed for various communications between the devices within such a wireless communication system may be adapted based upon any of a number of considerations. For example, a receiver communication device may indicate to a transmitter communication device one or more preferred sub-channels and/or channels on which subsequent communications are to be performed. Alternatively, a transmitter communication device may employ such information provided from one or more receiver communication devices as one of multiple respective considerations regarding which one or more sub-channels and/or channels on which subsequent communications are to be performed.

    摘要: Carrier sense multiple access (CSMA) for multiple user, multiple access, and/or MIMO wireless communications. In wireless communication systems that operate in supporting communications via one or more clusters, appropriate determination of when to begin making such transmissions on one or more clusters is made in accordance with intelligent carrier sense multiple access (CSMA) that may be performed in a number of different ways. In accordance with this, a cluster may be any combination composed of one or more channels among one or more bands. In supporting multi-cluster access, CSMA may be performed in selecting a primary cluster and performing backoff (e.g., countdown) thereon. After backoff is finished for the primary cluster, and the availability of one or more others clusters is checked, transmissions may be made using the available clusters. Alternatively, backoff may be made for each or multiple (a subset of) clusters or even individually for each respective cluster.
