A method of providing rate adaptation in a multi-user wireless communication system including single-user beamforming (SU-BF) and multi-user multiple-input multiple-output (MU-MIMO) is described. In this method, a master rate, which is a modulation and coding scheme (MCS) for the SU-BF, is determined. An MCS for each transmit mode is derived from the master rate using a rate mapping. Using the results from the mapping, the master rate, instead of the MCS for each transmit mode, is tracked. In one embodiment, a mapping calibration is periodically performed.

Method and system for unified rate adaptation for SU-BF and MU-MIMO operation

A method of operating a first wireless device includes sending a first message including a first intent to be a group owner and a value to a second wireless device. In addition, the method includes receiving a second message including a second intent to be the group owner from the second wireless device. Furthermore, the method includes determining which of the first wireless device or the second wireless device should be the group owner based on the first intent, the second intent, and the value.

Systems and methods for communicating packets having a plurality of formats are described herein. In some aspects, a signal (SIG) field in the preamble of a packet may indicate whether an extension field, such as an extension SIG field or SIG-B field, is included in the packet. In another aspect, one or more detectors may be used to auto-detect packets formatted as one of at least two different formats based on a short training field (STF) of a received packet. In some aspects, along training field (LTF) in the preamble of a packet may indicate whether the payload is repetition coded.

Systems and methods for wireless communication of packets having a plurality of formats

Certain aspects of the present disclosure relate to techniques for medium reservation in the case of multi-user (MU) communications. Multiple mechanisms are supported for protecting MU transmissions, wherein appropriate control messages can be exchanged between an access point and served user stations before transmitting downlink data packets.

Protection mechanisms for multi-user MIMO transmissions

A method includes determining, at an electronic device, information associated with a location of the first electronic device. An initial set of television white space channels is filtered based on the information to generate a search set of television white space channels. A passive scan of the search set of television white space channels is performed at the electronic device to identify a television white space access point.

Generating a search set of television white space channels based on location information

In a particular embodiment, a method includes applying a first stream to antenna mapping scheme to a preamble portion of a packet. The method further includes applying a second stream to antenna mapping scheme to a data portion of the packet. The second stream to antenna mapping scheme is applied to the data portion of the packet but not to the preamble portion of the packet. The second stream to antenna mapping scheme includes a circulation scheme or a cyclic delay diversity (CDD) scheme.

Systems and methods of using space time block codes

Methods and systems for signaling on a mixed-mode wireless network comprising a plurality of channels are provided. The mixed-mode wireless network includes high-throughput (HT) wireless devices and legacy wireless devices that use channels of the same width. The HT devices transmit data on at least two channels, while the legacy devices transmit on one channel. The distances between the HT channels and the distances between the legacy channels might differ, however, the channels used by the HT devices and the legacy devices may overlap. As a result, cooperation between the HT devices and legacy devices is provided to enable the devices to coexist on the same wireless network by minimizing collisions and interference. The HT devices are configured to send control information to the legacy devices to coordinate transmission by the HT devices with the legacy devices.

Advanced wireless packet transmission scheme with enhancements to accommodate basic wireless packet transmission scheme

A method includes sending, from a wireless device, an information element including at least one transmitter characteristic field. The at least one transmitter characteristic field includes information regarding a spectral mask associated with the wireless device and information regarding an antenna gain associated with the wireless device.

Various methods and apparatuses for channel selection based on energy levels are disclosed. In one aspect, an apparatus for communication is disclosed, the apparatus comprising a processing system configured to determine, for each of one or more channels, a plurality of energy levels of a respective plurality of signals received via a respective plurality of beam directions and to select one of the channels based on the determined energy levels and a transceiver configured to communicate over the selected channel.

Methods and apparatuses for channel selection

A modified preamble is used by extended devices that operate at higher rates, MIMO or other extensions relative to strict 802.11a-compliant devices. The extended devices might use multiple antenna techniques (MIMO), where multiple data streams are multiplexed spatially and/or multi-channel techniques, where an extended transmitter transmits using more than one 802.11a channel at a time. Such extensions to IEEE 802.11a can exist in extended devices. The modified preamble is usable for signaling, to legacy devices as well as extended devices, to indicate capabilities and to cause legacy devices or extended devices to defer to other devices such that the common communication channel is not subject to unnecessary interference. The modified preamble is also usable for obtaining MIMO channel estimates and/or multi-channel estimates. The modified preamble preferably includes properties that facilitate detection of conventional and/or extended modes ('mode detection') and provides some level of coexistence with legacy IEEE 802.11a devices.

Circuits, methods, and apparatus that provide high-throughput control fields that, among other functions, provide efficient TXOP handoffs in wireless networks. A handoff may be made by setting one or more bits in a field in a QoS frame, such as the HT control or other appropriate field. Various conditions may be placed on a handoff by a granting station. For example, conditions specifying where a station receiving a TXOP handoff may send data, what the receiving station may do with any remaining TXOP, or what types of data may be transmitted by the receiving station may be imposed. These various conditions may be combined or omitted in any logic combination.
