VARIABLE PACKET LENGTHS FOR HIGH-SPEED TRANSFER OF DATA PACKETS Russian patent published in 2008 - IPC H04L12/56 H04B7/26 

FIELD: communications systems.

SUBSTANCE: proposal is given of a method and device for generating a physical layer packet (PL) with variable length. Many security level packets (SL) can be multiplexed to a single PL-packet, so as to increase efficiency. SL-packets can vary their lengths. In one version, SL-packets of a different format for different users are joined in capsules, which a PL-packet. The shortest packets are meant for users with bad channel conditions or requiring less data, determined by use and associated requirements for quality of service (QoS). In one of the versions for modifying the header structure there are single-address and multiple user packets. An alternative version provides for modified sets of speeds, a mechanism for identification of an acknowledgment indicator ("АСК") from a single user packet or a multiplexed packet (delayed "АСК"). Amplitude manipulation for an "АСК"-channel is in contrast to bipolar manipulation, used in IS-856, and/or multivalent interpretation DRC.

EFFECT: increased efficiency through varying packet length.
