    摘要: Systems and methods for systems and methods for reliably broadcasting content to a plurality of users and facilitating distribution of portions of the broadcast content that either were not received by particular users, or were received with errors. In one embodiment, a wireless communication system is configured to broadcast content from a content source to a plurality of user devices. The content source is configured to provide the content to a base station. The base station parses the content into a plurality of segments and associates sequential identifiers with each of the segments. The content is then broadcast to each of the user devices. An identifier of an alternative data source is also provided to the user devices. When a mobile station receives the segments, it examines the segment identifiers to identify missing segments. The segments are then retrieved from the alternative data source identified by the base station.

    摘要: In one disclosed embodiment, communication between a mobile unit and a base station is performed at a data transfer rate selected from, for example, a finite set of HDR data transfer rates. Meanwhile, the mobile unit continually computes a moving average of the data transfer rates. The mobile unit also ascertains a supportable data rate for receiving data. The supportable data rate can be selected from a finite set of HDR data transfer rates. In order to maintain the moving average of the data transfer rate within a specified range, the mobile unit transmits maximum data rate requests or null data requests to the base station. The maximum data rates requested by the mobile unit are equal to or lower than the supportable data rate.
