Abstract
A wireless communication system may include a first transceiver that may concurrently keep at least two data units, such as payloads of data pending for transfer to a second transceiver (e.g., a targeted wireless communication device) over a communication link (e.g., a short-range radio link) on a communication channel. To wirelessly communicate with one or more networked wireless communication devices or systems, in one embodiment, the first transceiver is located in a device that may use a local link control and adaptation protocol capable of non-blocking data transfer operations. In one embodiment, pending multiple, data units are buffered to participate in a data streaming session. The transfer of the data units may be monitored to determine whether or not a data transfer operation was successful during the data streaming session. When the protocol learns that during the data streaming session a problem occurred with a data unit that was pending, the problem may be reported via an event instead of waiting for feedback to arrive from the targeted wireless communication device.
