    摘要: Methods and apparatus for performing channel tree operations in a communication system are disclosed that order a channel tree to effect improved computation speed for channel tree operations for scheduling channel resources in the communication system. The disclosed methods include mapping each of one or more node identifiers of real nodes of a channel tree to corresponding virtual node identifiers based on a prescribed ordering scheme. After mapping, the methods include performing one or more operations on one or more of the real nodes of the channel tree using the virtual node identifiers. Corresponding apparatus configured to execute the disclosed methods are also disclosed.

    摘要: Scheduling real-time Quality of Service (QoS) data flows in a large-scale wireless communications system uses credit allocation to active QoS flows based on quality-of-service weights, and the credits are measured in dimensionless units of air interface slot capacity. Scheduling addresses inactive QoS flows with no data pending for transmission that may accumulate up to a burst credits limit based upon a fair share of all credits that would be allocated in a 100% busy system. Intermittent flows such as echo requests or keyboard input can thereby get immediate service by using their burst credits. The flow with the highest credit accumulation is serviced first and may use up to a full time slot (or system quanta) of air interface time reducing header encapsulation overhead when payload sizes (and spectral efficiency) are low. Additive and multiplicative aspects age the negative credits back to zero whenever a flow overspends its credit allocation.

    摘要: Systems and methodologies are described that facilitate digital rights management in a wireless communication environment. Generally, content (e.g., data files, video images, etc.) can be downloaded and maintained in its encrypted state to ensure protection of digital rights. Consequently, programming applications that utilize such content decrypt the content at the time of use (e.g., playback or access). A file interface can be provided that allows applications to access encrypted content utilizing a standardized file I/O interface. Decryption of content can be transparent to individual applications utilizing encrypted content. Therefore, modifications cryptographic algorithms or procedures and changes in key sizes need not affect the programming applications.
