Packing source data packets into transporting packets with fragmentation

摘要

A communication system and method are disclosed for transmitting packets of information in at least one first format over a communications link that utilizes packets of information in a second format. In certain embodiments, the packets of information in a first format are converted to packets of information in the second format prior to transmission via the communications link by packing and fragmenting the information in the first format in a coordinated manner. Embodiments may also utilize packing subheaders and fragmentation control bits in the packing and fragmentation processes.

主权项

1. A method of transmitting data over a wireless communication link between a base station and mobile subscriber units, comprising:
establishing a service connection from the base station to a mobile subscriber unit; mapping variable length service data units (SDUs) associated with the service connection into variable length protocol data units (PDUs) associated with the service connection, the SDUs being mapped into the PDUs based at least in part on data carrying capacity provided by the base station for transmission to the mobile subscriber unit in a physical downlink sub-frame, the data carrying capacity based on at least one of a priority associated with the service connection, a modulation scheme and an error correction scheme used by the base station for transmission to the mobile subscriber unit; mapping the PDUs for the mobile subscriber unit into the physical downlink sub-frame; and transmitting the physical downlink sub-frame over the wireless communication link.
