Abstract: An aspect of the invention provides an efficient transportation of ESG fragments to a receiver through the formation of containers. A container comprises at least one ESG fragment, but may contain a plurality of fragments. A fragment may be also carried by more than one container. Aspects of the present invention utilize a simple and extensible header structure apart from the fragments and independent of the type and format of the individual fragments. In an aspect of the present invention, compression is applied over the entire container, including the fragments and any headers. In an aspect of the present invention, a 3GPP metadata envelope is carried within the container without the need for unnecessary repetition of parameters, such as for example, version, validity time, and identification. In an aspect of the present invention, a simplified container system allows for the updating of previously received fragments.

Abstract: The present invention provides a new and unique method or apparatus for checking if a next packet to be sent from a transmission buffer exceeds a predetermined threshold size when changing from a first mode to a second mode, for example, after a node, point, terminal or device in a wireless communications technology, such as a wireless local area network (WLAN), Worldwide Interoperability for Microwave Access Forum (WiMAX), Ultra Wide-Band (UWB), or other suitable network, enters into an active mode from an idle mode; and if so, then instead of the next packet transmitting a special first packet that is shorter than the next packet. The special first packet may include either a fragment of a longer packet on the transmission buffer or a null packet generated to probe a transmission link.

Abstract: Various embodiments are disclosed relating to a multicast-only data transmission mode in a wireless network. According to an example embodiment, an apparatus for wireless communications may include a controller. The apparatus, which may include an AP or a virtual AP may be configured to operate in a multicast-only data transmission mode (e.g., transmitting only multicast and/or broadcast data frames). The AP or virtual AP may operate in a multicast-only data transmission mode to handle multicast transmissions for one or more multicast streams for one or more wireless networks, for example.

Abstract: A method and apparatus are provided for communicating data between two nodes, points or terminals in a wireless local area network (WLAN) and providing information about each group address that has data waiting for delivery in one node, point or terminal. The two nodes, points or terminals may include an access point (AP) or other suitable network node, point or terminal, and a station (STA) or other suitable network node, point or terminal in the WLAN. The information about each group address may form part of an information element in a beacon provided from an access point to one or more nodes, points or terminals in the WLAN.

Abstract: Provided are apparatuses and methods for transmitting and receiving timing information corresponding to updating parameters in an Electronic Service Guide (ESG) fragment. The parameters may be associated with a session of a program or service corresponding to the ESG fragment. In one example, the parameters may be updated and a timing information such as an RTP timestamp may be provided for indicating a time when the parameters may be loaded or implemented. In this example, when the RTP timestamp is greater than or equal to a timestamp of a data packet in a data stream, the time for the parameter change may have been achieved. At this time, the new or updated parameters may be loaded at a receiver.

Abstract: Provided are apparatuses and methods in a digital broadcast transmission system for managing ESG fragments of a service guide at a receiver or subscriber terminal. In one example of the invention, an ESG fragment containing one of a start time or a stop time of a corresponding program or service is received at a subscriber terminal or receiver. The receiver may compare the start time and/or stop time with a current time. Based on the comparison, the ESG fragment may be stored in memory. If an ESG fragment is stored in memory and a subsequent corresponding ESG fragment is received, then based on the comparison step, the receiver may delete the ESG fragment in memory or maintain the ESG fragment in memory.
