Abstract: A system and method are disclosed that may allow for enhanced gain control for two radios. In an example method, a first radio may receive a wireless signal on a first frequency band, the wireless signal including at least a header and a payload. A first gain control operation may be performed based at least in part on information in the header of the wireless signal. A second radio may be determined to initiate a transmission on a second frequency coinciding with the first frequency band before reception of the wireless signal is completed, where the second radio is co-located with the first radio. A second gain control operation may be performed based at least in part on an expected interference associated with the transmission from the second radio, and one or more gain levels may be adjusted for reception of the wireless signal, based on the second gain control operation.

Abstract: A method and apparatus for connecting a wireless station (STA) to an access point (AP). The STA broadcasts a probe request that includes a custom information element (IE), and receives probe responses from one or more APs in response to the probe request. The STA then identifies a target AP from the probe responses based at least in part on whether one or more of the received probe responses include the custom IE, and connects to the target AP. For example, the target AP may respond to the probe request by sending a probe response that includes the custom IE. The STA may thus identify a set of candidate APs based on one or more received probe responses that include the custom IE, and select the target AP from the set of candidate APs.

Abstract: A modulation and coding scheme (MCS) is selected for one or more transmissions from a first wireless device to a second wireless device, based at least in part on interference at the second wireless device during a time period. The interference excludes wireless signals present at the second wireless device at first times during the time period when the first wireless device is transmitting and at second times during the time period when the first wireless device detects transmissions.
