Abstract: Wider bandwidth transmissions are dynamically enabled in a wireless networking environment. During a transmit opportunity time interval for a wireless network device, a transmission is sent in a primary channel in a frequency band in which the primary channel and a secondary channel may be used simultaneously to send a wider bandwidth transmission. Activity is monitored in the secondary channel. A determination is made as to whether the secondary channel is free based on the monitoring. When it is determined that the secondary channel is free, the wider bandwidth transmission is sent in the primary and secondary channels.

Abstract: Techniques are provided herein to allow a wireless network access point (AP) to more fully use its bandwidth in order to leverage the different bandwidth capabilities of different types of wireless client devices that the AP serves. The AP generates control parameters for usage of a plurality of channels in a bandwidth during a downlink transmission interval. The control parameters comprise information indicating channel assignments that result in multiple downlink transmissions that at least partially overlap in time to different wireless client devices according to their respective bandwidth capabilities. The AP transmits the control parameters in a control frame in advance of the downlink transmission interval on each of the plurality of channels in the bandwidth.

Abstract: Techniques are provided to determine whether or not incident power at a wireless communication device in at least two frequency channels is from the same device. Incident power in frequency channels allocated to a basic service set in a wireless network is received at a plurality of antennas of the wireless communication device. Channel state information is computed for at least two frequency channels allocated to the basic service set. One or more metrics are generated based on the channel state information in the two frequency channels. The one or more metrics are evaluated to characterize an uplink signal bandwidth associated with the two channels to determine whether or not the incident power in the two channels is from the same device.

Abstract: Techniques are provided for a multi-user reservation sequence used when transmitting a multi-user transmission in a wireless network. At a wireless access point device configured to operate in a wireless network, a multi-user request-to-send packet is transmitted as part of a multi-user reservation sequence prior to a multi-user transmission from the wireless access point device to a plurality of wireless client devices that are the intended recipients for the multi-user transmission. The multi-user request-to-send packet comprises duration information and address information configured to address at least some of the plurality of wireless client devices. Clear-to-send packets transmitted from two or more of the plurality of wireless client devices in response to the multi-user request-to-send packet are received at the wireless access point device. Each clear-to-send packet comprises identical content. In some scenarios, the multi-user request-to-send packet is preceded by a single-user request-to-send packet directed to a designated wireless client device.

Abstract: Techniques are provided to enable group addressing for multicast transmissions in a frame that is configured to support multi-user transmissions. The frame comprises a header field that is configured to indicate to recipient devices associated with a multi-user transmission interval during which time, frequency and spatial channel resources are allocated to allow for the transmission of a data frame or simultaneous transmission of corresponding ones of a plurality of data frames to respective recipient devices. In the header field, group identification information is wirelessly transmitted that indicates a group of recipient devices which are to receive a transmission during the multi-user transmission interval. Data is wirelessly transmitted for a multicast transmission during the multi-user transmission interval that follows the header field, where the multicast transmission is intended for a group of recipient devices that are members of a multicast group corresponding to group identification information contained in the header field.

Abstract: Techniques are provided for selecting channels for use by access points operating in a wireless local area network. Metrics are computed for at least one set of radio frequency (RF) channels, wherein the set of RF channels comprises at least two RF channels in a frequency band that are available for use by a wireless network for a wider bandwidth mode that combines bandwidth of two or more RF channels. Alignment of individual primary and secondary RF channels is determined in the set of RF channels for operation of at least first and second wireless networks. A bias is applied to the metrics for each RF channel that is a member of the set of RF channels for the primary channel depending on alignment of the primary and secondary channels of the respective first and second wireless networks to produce adjusted metrics, based on which RF channels are assigned.
