Patent ID: 8634433

Claim:
A method of transmitting data from a radio network to a plurality of user equipment devices, the method comprising: transmitting from the radio network to a first user equipment device of the plurality of user equipment devices a first type of control information relating to a transmission time interval (TTI), the first type of control information comprising indications of code allocation and modulation technique of transmission of payload data to the first user equipment device during the TTI, wherein said transmitting includes transmitting from the radio network to the first user equipment device further instances of said first type of control information that respectively relate to subsequent said TTIs; sending a message from the radio network to at least the first user equipment device, the message comprising a second type of control information, the second type of control information comprising information regarding code allocation and modulation technique of transmission of payload data to at least a second user equipment device of the plurality of user equipment devices during the TTI, the second user equipment device being different from the first user equipment device, wherein said sending includes sending from the radio network to at least the first user equipment device further said messages that respectively include further instances of said second type of control information that respectively relate to said subsequent TTIs; defining a partition of an available set of codes into first and second subsets, wherein codes of said first and second subsets are available only for transmission of payload data using first and second modulation techniques, respectively; and prohibiting said partition from changing until said partition has obtained for at least two consecutive said TTIs; wherein each of the plurality of user equipment devices comprises a decision feedback equalizer to equalize and reduce interference in the payload data that has been received using the first type and the second type of control information to configure the decision feedback equalizer.
