Abstract: Embodiments include a method, computer program product, and system for grouping electronic devices into contention groups to reduce uplink Orthogonal Frequency-Division Multiple Access (OFDMA) random access (OFDMA-RA) collisions. An access point may explicitly assign an electronic device to a contention group, or the electronic device may implicitly determine an assignment to the contention group. To explicitly assign a device to a contention group, the access point may randomly assign or assign based on a criteria of the electronic device. Examples of criteria include an association identifier (AID), a traffic type/quality of service (QoS) category, a power saving preference, and an association status. The electronic device may implicitly determine a contention group assignment based on the total number of contention groups. The electronic device may use the explicitly or implicitly assigned contention group number to determine whether the electronic device may contend for a given trigger frame random access (TF-R) frame.

Abstract: The disclosed embodiments provide a system that provides wireless service groups. During operation, a wireless device's advertising mechanism advertises a service group over Wi-Fi, wherein the service group comprises at least the wireless device and wherein the service group's security requirements regulate multicast protection within the service group. In response to receiving a request from a second device to be admitted into the service group, the wireless device's security mechanism admits the second device into the service group and sends the service group's security requirements to the second device, thereby enabling the second device to initialize multicast protection in accordance with the service group's security requirements.

Abstract: The disclosed embodiments provide a system that enables service-configurable wireless connections. During operation, a local service endpoint of a service runs on a wireless device. The local service endpoint sends a request to establish a datapath with another service endpoint on another device. Meanwhile, the wireless device's service discovery module discovers a remote endpoint for the service on a remote device. In response to the request, the wireless device's service-configurable security entity configures a Wi-Fi connection's security configuration, thereby enabling the local endpoint to establish a datapath between the local endpoint and the remote endpoint over the Wi-Fi connection.

In another embodiment, a wireless device may receive a first data frame including first configuration information and further including a request that the wireless device configure its receiver according to the first configuration. In response, the wireless device may configure the receiver according to the first configuration. In either case, the wireless device may receive subsequent communications according to the first configuration.

Abstract: A wireless device may use 2.5 MHz narrow band channel spacing. In some embodiments, clear channel assessment based listen before talk may be used to determine if a channel is idle or busy. In some embodiments, randomized channel access may be achieved using a pseudo random number generator on an allowed list of channels. In some embodiments, an avoid loitering mechanism may be employed to reduce interference with transmitters using the same frequency bands.

Abstract: During operation, an electronic device may perform, using a scanning radio, a scan of a band of frequencies, where the scanning radio only receives frames. Then, the electronic device may receive, using the scanning radio, a beacon frame associated with a second electronic device, where the beacon frame includes information associated with operation of a third electronic device in a second band of frequencies. Next, the electronic device may perform, using a data radio, a second scan of the second band of frequencies based at least in part on the information, where the data radio transmits and/or receives second frames, and where the second scan is performed, at least in part, while the scan is performed. Note that the electronic device may not be associated with (or may not have a connection with) the second electronic device and/or the third electronic device.

Abstract: An electronic device is described. This electronic device may associate with a second electronic device (such as an access point) in a WLAN. While associating or associated with the second electronic device, the electronic device may receive, from the second electronic device, an AID corresponding to the electronic device for use when communicating frames in the WLAN. Moreover, while associated with the second electronic device, the electronic device may obtain a second AID corresponding to the electronic device for use when communicating second frames in the WLAN, where the associating includes replacing the AID with the second AID. Note that obtaining the second AID may include: the electronic device selecting the second AID from a predefined set of AIDs, which were previously received from the second electronic device; or the electronic device receiving, from the second electronic device, the second AID.

Abstract: During operation, an electronic device (e.g., an access point) may provide a multi-user (MU)-request-to-send (RTS) frame that communicates an RTS in a channel associated with the second electronic device and a second RTS in a second channel associated with a third electronic device. For example, the channel may include a primary channel and the second channel may include a secondary channel. Note that the third electronic device may include a SST station and the second electronic device may include a non-SST station. Then, the electronic device may receive an MU-clear-to-send (CTS) frame that includes a CTS in a third channel associated with the third electronic device. Moreover, the third channel may be equal to or a subset of the second channel, and/or the third channel may include a CTS reception channel associated with the electronic device.
