Abstract: Methods and systems for processing signals in a receiver are disclosed herein and may comprise receiving spatially multiplexed signals via M receive antennas. A plurality of multiple data streams may be separated in the received spatially multiplexed signals to detect MIMO data streams. Each of the MIMO data streams may correspond to a spatially multiplexed input signal. Complex phase and/or amplitude may be estimated for each detected MIMO data streams utilizing (M-1) phase shifters. Complex waveforms, comprising in-phase (I) and quadrature (Q) components for the MIMO data streams within the received spatially multiplexed signals may be processed and the processed complex waveforms may be filtered to generate baseband bandwidth limited signals. Phase and/or amplitude for one or more received spatially multiplexed signals may be adjusted utilizing the estimated complex phase and amplitude. Phase and/or amplitude may be adjusted continuously and/or at discrete intervals.

Abstract: A device may use positioning information to increase the efficiency a wireless local area network (WLAN) scanning process. To determine the presence of WLANs within range, a device may determine its own location. For example, the device may determine its own location using a satellite-based navigation system. The device may then determine a wireless scanning strategy based on the determined location. The determination may be further based on connection parameters, such as, channel information, network capabilities, and/or other connection parameters.

Abstract: 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.).

Abstract: 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.

Abstract: Scheduled clear to send (CTS) for multiple user, multiple access, and/or MIMO wireless communications. Before sending transmissions, a request to send (RTS)/clear to send (CTS) exchange takes place between a transmitting wireless communication device and multiple receiving wireless communication devices may take place therein. The transmitting wireless communication device (e.g., an AP) may generate and transmit a multi-user request to send (mRTS) frame to a number of receiving wireless communication devices (e.g., STAs). The mRTS frame can include information and instructions therein to direct the manner by which all or a subset of the receiving wireless communication devices are to provide CTS responses back to the transmitting wireless communication device. The mRTS frame may be an OFDMA frame, a MU-MIMO frame, or a combination thereof. The CTS responses may be received in accordance with any one or combination of OFDM signaling, OFDMA signaling, and MU-MIMO signaling.

Abstract: Aspects of a method and system for controlling access and utilization of femtocells via a network based service are provided. In this regard, a femtocell management entity communicatively coupled to a network and operable to manage one or more femtocells may be accessed via an end-user communication device. In this manner, the femtocell(s) may be managed via the end-user device such as one of the cellular enabled communication devices. The femtocell management entity may enable establishing one or more SLAs between the femtocell(s) and the cellular enabled communication device(s). The SLA(s) may enable the cellular enabled communication device(s) to establish one or more cellular communication channels with the femtocell(s). The SLA(s) may determine when the cellular communication channels may be established. The SLA(s) may determine how a femtocell owner/operator may be compensated for providing cellular service. The femtocell(s) may be accessed utilizing Internet Protocol.

Abstract: Phase rotation for preambles within multiple user, multiple access, and/or MIMO wireless communications. An appropriately designed phase rotation vector and/or appropriately designed cyclic shift delays (CSDs) are applied to respective sub-band components of the preamble. With appropriately designed CSDs, certain fields within the preamble are not modified. For example, a legacy short training field (L-STF) of the preamble is not changed when using appropriately designed CSDs. The respective CSDs may be implemented as integer multiples of a common CSD (e.g., 0×CSD, 1×CSD, 2×CSD, etc. such that one of the values of such a CSD vector may be zero [0], another may be the common CSD itself, etc.). Also, by employing an appropriately designed phase rotation vector and integer multiples of a CSD to a preamble, the respective peak to average power ratio (PAPR) between different respective fields within the preamble may be minimized.
