Abstract:
In a wireless communication system, a method for transmitting data to a plurality of terminals, comprising:assigning each of the plurality of terminals a respective channelization code used to channelize data transmitted in non-compressed frames for the terminal, wherein the data for each non-compressed frame is transmitted within a defined time period; selecting a common channelization code used to channelize data transmitted in compressed frames for the plurality of terminals, wherein the data for each compressed frame is transmitted within a shortened time period compared to the defined time period for a non-compressed frame; scheduling transmission of compressed frames for the plurality of terminals such that compressed transmissions are non-overlapping; channelizing non-compressed frames for each terminal with the channelization code assigned to the terminal; and channelizing compressed frames for the plurality of terminals with the common channelization code; wherein the common channelization code has a length that is half of the length of the shortest channelization code assigned to the plurality of terminals.
