Abstract  Abstract

method and apparatus for generating physical layer of variable length (PL) packet. multiple security layer (SL) packet may be multiplex into a single PL packet to increase efficiency wherein the SL packets may have variable lengths. In one embodiment a SL packets of different formats of different users are combined in a container the container forming the PL packet. the short packet is used in poor channel condition of the user or the application and quality of service (QoS) requirement and needs less amount data of the user. In one embodiment the header structure of the modified prescribed unicast or multi-user packet. optional embodiment provides modified rate set for identification from a single-user packet or a multi-user packet (delayed ACK) ACK mechanism. on-off keying for ACK channel with in the IS-856 bipolar phase shift keying and/or value of the DRC of the explanation.

Method and apparatus for variable length Physical Layer (PL) packet generation. Multiple Security Layer (SL) packets may be multiplexed into a single PL packet to increase efficiency wherein the SL packets may have variable lengths. In one embodiment different format SL packets for different users are combined into capsules that form the PL packet. Shorter packets are for users in poor channel conditions or requiring smaller amounts of data due to the applications and the accompanying Quality of Service (QoS) requirements. In one embodiment a modified Preamble structure provides for Unicast or multi-user packets. Alternate embodiment provides modified Rate Sets a mechanism for identifying ACK from a single-user packet or a multiplexed packet (delayed ACK). ON/OFF keying for ACK channel v/s bi-polar keying used in IS-856 and/or multi-valued interpretation of DRC.
