A method and wireless transmit/receive unit (WTRU) for transmitting data over an enhanced uplink (EU) channel is disclosed. The WTRU receives a scheduled grant and at least one non-scheduled grant. The WTRU transmits a medium access control for EU channel (MAC-e) protocol data unit (PDU) over an EU channel. The MAC-e PDU includes multiplexed data. The multiplexed data includes scheduled data. An amount of the multiplexed data is not greater than a size of a largest supported EU transport format combination (E-TFC) size that does not exceed a size based on the received scheduled grant, the received at least one non-scheduled grant, and a power offset. The MAC-e PDU is transmitted based on a selected E-TFC. The selected E-TFC is a smallest E-TFC that supports the multiplexed data of the MAC-e PDU.

Embodiments may be disclosed herein that provide systems, devices, and methods of operating a Multimedia over Coax (MoCA) network. One such embodiment is a method comprising: aggregating packets, including at least control packets and acknowledgement packets, with other packets.

A transmitter includes a buffer programmed to queue packets and a computing device having a processor and a data storage medium. The computing device is programmed to generate at least two sub-packets from each of the plurality of packets stored in the queue. For each sub-packet, the computing device is programmed to identify a plurality of transmission opportunities. Each transmission opportunity is associated with one of a plurality of networks. The computing device is further programmed to select among the plurality of transmission opportunities and transmit the sub-packet over the network associated with the selected transmission opportunity.

Disclosed herein is a specialized integrated circuit for a Test and Training Enabling Architecture (TENA) gateway. The specialized integrated circuit comprises a packet parser, a TCP packet handler, generic TENA packet generator(s), and object model specific TENA packet generator(s). The packet parser parses an incoming MAC layer packet and conditionally provides a TCP packet to the TCP packet handier, depending on header(s) in the MAC layer packet. The TCP packet handler parses the TCP packet to reveal a TENA message, and determines whether the TENA message involves object model specific data and selectively provides the TENA message to the generic TENA packet generator(s) or to the object model specific TENA packet generator(s). The selection is based on the object model specific data determination. The selected TENA packet generator constructs an outgoing TENA message in response to the provided TENA message.

Disclosed are a method and an apparatus for retransmission in a wireless LAN. The method for retransmission in a wireless LAN may comprise the steps in which: an STA receives an RTS frame from an AP; the STA transmits a CTS frame to the AP in response to the RTS frame; the STA receives an initial data frame from the AP after transmitting the CTS frame; if decoding on the initial data frame is impossible, the STA transmits a retransmission request frame to the AP; and the STA receives a retransmission data frame from the AP in response to the retransmission request frame.

Some demonstrative embodiments include devices, systems and/or methods of wireless communication. For example, a wireless communication unit may include a Multi Media-Access-Control (MAC) Address Station-Management-Entity (MM-SME) managing a plurality of MAC entities having a respective plurality of MAC addresses. The wireless communication unit may transmit a frame including a Multi-MAC-Addresses-Element (MMAE), which includes two or more MAC addresses of the plurality of MAC addresses and a control field defining at least one common communication attribute to be applied to the two or more MAC addresses.

An electronic device is provided. The electronic device includes: a first board that time-divides each of a plurality of parallel data and generates a plurality of packets corresponding to each time period based on levels of each of the plurality of parallel data included in each time period in order to convert the plurality of parallel data into serial data; and a second board that determines levels of each of the plurality of parallel data in each time period to convert the serial data into the plurality of parallel data when the serial data are received from the first board, in which the first board may convert the data into a first signal or a second signal based on the levels of the data included in each time period in order to generate the packets.

An encoding device performing an encoding process according to an encoding scheme using a CTS indicating time at which presentation or reproduction is performed, comprising: an encapsulator that generates a media unit in which one or more access units encoded by the encoding scheme are capsulated, and a transmitter that transmits information indicating an absolute time of an access unit included at a top portion of the media unit, in addition to the media unit, wherein the encapsulator adds a CTS relative value to the n.sup.th access unit included in the media unit, the CTS relative value being a difference between the CTS of the n.sup.th access unit and the DTS of the n+1.sup.th access unit.

A communication system uses multiple communications links, preferably links that use different communications media. The multiple communications links may include a high latency/high bandwidth link using a fiber-optic cable configured to carry large volumes of data but having a high latency. The communications links may also include a low latency/low bandwidth link implemented using skywave propagation of radio waves and configured to carry smaller volumes of data with a lower latency across a substantial portion of the earth's surface. The two communications links may be used together to coordinate various activities such as the buying and selling of financial instruments.

In a method for generating a physical layer (PHY) data unit for transmission via a communication channel, information bits to be included in the PHY data unit are received. A number of padding bits are added to the information bits. The number of padding bits is determined based on respective virtual values of each of one or more encoding parameters. The information bits are parsed to a number of encoders and are encoded, using the number of encoders, to generate coded bits. The coded bits are padded such that padded coded bits correspond to respective true values of each of the one or more encoding parameters. The PHY data unit is generated to include the padded coded bits.
