P dot over, Erik Dahlman, Stefan Parkvall: Hybrid ARQ for packet data transmission. Telefonaktiebolaget L M Ericsson, Nixon & Vanderhye P C, December 20, 2005: US06977888 (107 worldwide citation)

A hybrid ARQ scheme is used incremental data packet combining. In an example embodiment, the hybrid ARQ scheme with incremental data packet combining employs three feedback signaling commands: ACK, NACK, and LOST. Using these three feedback commands, the hybrid ARQ scheme with incremental data packe ...

P dot over, Erik Dahlman, Stefan Parkvall: Two stage date packet processing scheme. Telefonaktiebolaget LM Ericsson, Nixon & Vanderhye P C, February 13, 2007: US07178089 (16 worldwide citation)

Data packets are efficiently combined to fit into a transmission interval. A current communications condition, e.g., the current channel quality, is detected and used to select an appropriate combination of modulation and channel encoding parameters. However, data packets are combined and pre-encode ...

Erik Dahlman, Stefan Parkvall: Cellular radio communication system with frequency reuse. Telefonaktiebolaget LM Ericsson, Nixon & Vanderhye P C, June 5, 2007: US07227850 (14 worldwide citation)

Different frequency reuse values are associated with different channels, e.g., different types of channels in a cellular communications system. For a high speed downlink shared type of channel, the frequency reuse may be greater than one in order to achieve higher data rates. On the other hand, the ...
