Abstract:
A wireless device may be configured to operate in one of two modes where each mode uses a different channel list to perform operations in accordance with the IEEE 802.11 standard. In a first mode, the wireless device operates as an access point that sets up channels using one channel list in order to facilitate communications within a basic service set (BSS). In a second mode, the wireless device uses a second channel list to operate as a station and scan for a BSS. The first channel list contains a subset of the channels contained in the second channel list. The channels in each respective channel list may be reconfigured to adapt to changes in the configuration of a BSS and the devices communicating therein.
Abstract:
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.
Abstract:
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.

Abstract:
A method includes transmitting a packet from a first wireless device to a second wireless device, where data within the packet is encoded and a signal representing the packet is modulated in accordance with a modulation and coding scheme (MCS). The method also includes, responsive to receiving an acknowledgement packet that includes a MCS change indicator from the second wireless device via a wireless local area network (WLAN) in response to transmitting the packet, maintaining the MCS when the MCS change indicator has a first value and incrementing the MCS when the MCS has a second value.
