A cloud marketplace includes a network of data centers that collectively allow users to search and purchase products, including applications and extensions to applications. Each data center supports a marketplace module that executes on computing resources to offer users the products and receive and send product metadata descriptive of the products. Each product has a distribution list which specifies one or more data centers as a potential destination to list the product. The distribution list supports region-specific synchronization of products and product listings and can be updated automatically responsive to region-specific policies or regulations to list, delist, or relist products in one or more regions.

Selective synchronization in a cloud marketplace

A method and apparatus are provided for processing a Class-3 MAC Data frame. The Class-3 MAC Data frame may include a Type field, a Subtype field, and a Class-3 MAC Data frame-specific MAC subheader that includes a basic service set identifier (BSSID) field, an association identifier (AID) field, and a direction indicator. A station (STA) may determine the intended recipient of the Class-3 MAC Data frame based on the BSSID field, the AID field, and the direction indicator.

Methods for MAC frame extensibility and frame specific MAC header design for WLAN systems

Enhanced protocols and devices may be used to alleviate loss of spectrum efficiency in wideband transmission. The protocols may implement a wideband transmission opportunity (TXOP) truncation where one or more of the channels involved in communication over the wideband are released. In one scenario, an access point (AP) may receive, from a wireless transmit receive unit (WTRU), a first CF-End frame that includes a duration field and a basic service set identifier (BSSID) field that includes an individual/group bit. On a condition that the individual/group bit of the BSSID field has a value of one (1), the AP may determine that a scrambling sequence of the first CF-End frame indicates a bandwidth associated with a transmit opportunity (TXOP) being truncated by the WTRU. The AP may then transmit a second CF-End frame at the bandwidth indicated by the scrambling sequence of the first CF-End frame.

Method and apparatus for supporting wideband and multiple bandwidth transmission protocols

A wireless station comprises a receiver that is configured to receive a frame from an access point (AP). The frame comprises a physical layer header. The physical layer header includes an indication of a color associated with the AP. A processor in the STA is configured to enter a power save state based on the color associated with the AP not matching a stored AP color of an AP that the STA is associated with. An AP that performs a similar function is also disclosed.

Method and apparatus for efficient addressing and power savings in wireless communications

A method and apparatus for power savings in a wireless local area network (WLAN) are disclosed. A station (STA) may receive parameters that associate the STA to a specific group of STAs and perform a channel access during a period that is allowed for the group of STAs based on the parameters. The STA may receive information regarding an access slot that is allowed for the group of STAs and access a channel during the access slot. The STA may receive a schedule for wake up from a doze state and goes in and out of the doze state based on the schedule. A highest channel access priority may be provided to a sensor or meter type of STA. The STA may indicate to an access point (AP) that the STA will not listen to a traffic indication map (TIM) or a delivery TIM (DTIM) in a beacon.

Method and apparatus for power savings in a wireless local area network

A method performed by a STA may comprise receiving a frame, from a first AP including an indication of a configuration change counter (CCC) associated with a second AP. The CCC may be an unsigned integer that increments when an update to one or more AP parameters of the second AP has occurred. The method may further comprise establishing a first wireless link with the first AP and establishing a master key via at least the first wireless link.

Station and method for receiving a frame comprising a configuration change counter corresponding to another access point

A method for receiving a backoff value at a wireless station is presented. A traffic indication map is received at the station, wherein a backoff number is implicitly assigned to the station based on a position of the station within the traffic indication map. The backoff value is determined by multiplying the backoff number by a predetermined time value.

Supporting a large number of devices in wireless communications

A method performed by a STA may comprise receiving, from an access point, a RTS frame having a duration field and transmitting, to the AP, in response to receiving the RTS frame, a CTS frame. The method may further comprise receiving, from the AP, data of a MU data unit addressed to the STA and another STA and, in response, transmitting an ACK frame, to the AP. The data may be received by the STA on a subset of sub-carrier frequencies of which the MU data unit spans and the MU data unit and the ACK frame may be transmitted within a duration indicated by the duration field.

Group transmissions in wireless local area networks

A method and system for improving responsiveness in exchanging management and control frames in a wireless local area network are disclosed. An initiator sends a frame (action frame, management frame, CSI frame, control frame, or data frame) to a responder. Upon correctly receiving the frame, the responder sends a response frame to the initiator instead of directly sending an acknowledgement (ACK) packet. The responder preferably accesses the wireless medium to send the response frame in a short inter-frame spacing (SIFS). With this scheme, a long delay associated with having to contend for the wireless medium to send the response frame is avoided and therefore, the responsiveness and timeliness of the feedback mechanism is significantly enhanced. The response frame may be piggybacked on or aggregated with another packet.

Method and system for improving responsiveness in exchanging frames in a wireless local area network

A method performed by a STA may comprise transmitting a first negotiation message to an AP and receiving a second negotiation message from the AP. The first negotiation message and the second negotiation message may negotiate a block acknowledgement agreement. The method may further comprise receiving a data unit, from the AP, the data unit having a duration field indicating a duration of a block-ACK frame. The duration of the block-ACK frame may be determined based on the negotiated block ACK agreement. A block-ACK frame may be transmitted within the duration indicated by the duration field.

Method and apparatus for negotiating a block acknowledgement agreement

Live-custom recording functionality is described. Live-custom recording can help a teleconferencing participant overcome situations where the participant may, for example, not have been attentive and therefore may have missed what was communicated. Another example of a situation that can be overcome with techniques described in this paper is one in which the participant cannot hear the speaker due to inadequate or low bandwidth and network connectivity issues. An enhanced conference recording functionality such as the live-custom recording functionality proposed and described herein is designed to capture applicable segments or clips of the teleconference meeting.

Live-custom recording

The disclosed badge creation systems and methods aim at reducing queuing time at badge preparation and distribution. The invention discloses creating a pre-printed badge with locally printed label, a partially locally printed badge, a fully locally printed badge, or a combination of these; determining privacy policy compliance for a selected badge type; and specifying a compliant dataset that is privacy policy compliant in accordance with the privacy compliance determination.

Physical badge creation

A method performed by STA may comprise receiving, from a first AP, a first beacon frame comprising a first relay information element including a first field that indicates whether a root AP BSSID field is included in the first relay information element, determining that a first root AP BSSID field is included in the first relay information element and determining that the first AP is a relay AP of a root AP identified by the first root AP BSSID field. The method may further comprise receiving, from a second AP, a second beacon frame comprising a second relay information element including a second field that indicates whether a root AP BSSID is included in the second relay information element and determining that a root AP BSSID field is not included in the second information element and determining that the second AP is a root AP.
