摘要:
Methods and apparatus for packetization of content for transmission over a network. A method is provided that includes generating one or more content packets from the multimedia content, wherein the content packets are associated with a time reference, and adding a sync header to the one or more content packets to form one or more application layer packets, respectively, wherein the sync header comprises a time indicator that indicates time relative to the time reference. An apparatus includes encoding logic configured to generate one or more content packets from the multimedia content, wherein the content packets are associated with a time reference, and packetization logic configured to add a sync header to the one or more content packets to form one or more application layer packets, respectively, wherein the sync header comprises a time indicator that indicates time relative to the time reference.

Techniques for transmitting overhead information to facilitate efficient reception of individual data streams are described. A base station may transmit multiple data streams on multiple data channels (or MLCs). The MLCs may be transmitted at different times and on different frequency subbands. The time-frequency location of each MLC may change over time. The overhead information indicates the time-frequency location of each MLC and may be sent as “composite” and “embedded” overhead information. The composite overhead information indicates the time-frequency locations of all MLCs and is sent periodically in each super-frame. A wireless device receives the composite overhead information, determines the time-frequency location of each MLC of interest, and receives each MLC at the indicated time-frequency location. The embedded overhead information for each MLC indicates the time-frequency location of that MLC in the next super-frame and is transmitted along with the payload of the MLC in the current super-frame.
摘要:
A wireless communications device is configurable to communicate with either one of two networks over a wireless medium, each of the two networks having a different air interface protocol. Additionally, the wireless device includes stored provisioning information for a set of networks of a first type and can map this first provisioning information into a second format for use with networks of a second type. The device also includes a non-volatile memory for storing default provisioning information so that some information remains available regardless of what is erased from the memory. The default provisioning information is enough to establish a connection over one of the available networks and allow reconstruction of a provisioning list.

Conserving power for coded transmissions comprises ceasing to process parity packets once associated data packets are deemed correct or corrected. Once data packets are deemed correct or corrected, the receiving unit can shut off during the transmission of parity packets.

Provided is a method and system for enhancing acquisition latency in a communications network. The method includes identifying control information associated with transmitted information and fragmenting the identified control information. Each fragment of control information is then associated with a corresponding transmission unit of the transmitted information. This process facilitates independent decoding and processing of the control information, which is embedded within physical layer packets.
