Abstract: A first access point (AP) detects a communication between a client device and a second AP. The first AP determines at least one criteria for AP steering is satisfied. AP steering is then used by the first AP to cause the client device to associate with the first AP, or a particular network of the first AP. For example, the first AP may transmit a disassociation message to the client device. The disassociation message may identify the second AP associated with the client device and cause the client device to disassociate from the second AP. After the client device disassociates from the second AP, the client device may select and associate with the first AP. The first AP may manage which network the client device associates with using a blacklist at the first AP.

Abstract: A hybrid device can be configured to execute operations to select singleton coordinating functionality in a hybrid communication network. In one embodiment, a single master device (e.g., a hybrid device configured as both a registrar and a central access point (CAP)) can be selected. The hybrid device can transmit search messages to detect an existing master device and/or to identify other hybrid devices contending to become the master device. The hybrid device with the preferred device identifier is selected as the master device. In another embodiment, operations for selecting the coordinating functionality are split into two independent stages—a CAP selection stage and a registrar selection stage. In the CAP selection stage, the hybrid device with a preferred device weight (or a preferred device weight and a preferred device identifier) is configured as the CAP. In the registrar selection stage, similar operations can be executed to select the registrar.

Abstract: A hybrid device can implement functionality to automatically configure itself to form a home network with other network devices. If it is determined that the hybrid device is the central access point of a hybrid network, operating parameters are determined for the central access point. The central access point can then operate in conjunction with other non-CAP hybrid devices of the hybrid device to determine how to configure the non-CAP hybrid device. The configuration of the non-CAP hybrid device can be determined based, at least in part, on a communication link performance measurement between the CAP and the non-CAP hybrid device. Furthermore, the hybrid network can also be monitored to ensure that the hybrid devices do not repeatedly or randomly switch between different configurations.

Abstract: Systems and methodologies are described that facilitate selecting an uplink carrier for random access within a wireless environment having multiple carriers. Selection of an uplink carrier for random access can be randomly selected from a set of available uplink carriers. Additionally, the uplink carrier for random access can be selected based upon which uplink carrier is paired with an anchor carrier. Further, the uplink carrier for random access can be identified based upon a bandwidth related to the user equipment (UE). Reference signals can also be employed in order to identify an uplink carrier to perform random access.

Abstract: This disclosure provides methods, devices and systems for non-simultaneous transmit and receive (STR) station (STA) transmissions using multiple links. In one aspect, a medium synchronization delay timer associated with a second link of the non-STR STA can be initiated in response to completing transmission of the data on the first link to delay triggering of a clear channel assessment (CCA) associated with the second link. Data can be transmitted on the second link in response to expiration of the medium synchronization delay timer. In another aspect, an energy detect (ED) threshold level on a second link may be decreased from a first ED threshold level to a second ED threshold level after transmitting the data on the first link. In a further aspect, a block acknowledgment (BA) frame including a network allocation vector (NAV) synchronization of a second access point may be transmitted to the first link of the station.
