1. A method comprising:
a) receiving, by a wireless device, at least one control message from a first base station, said at least one control message causing configuration of measurement parameters of said wireless device, said configuration triggering measurements of channel state information corresponding to a subset of carriers, said at least one control message causes configuration of:
i) a channel state information transmission period;ii) a channel state information transmission resource;iii) a channel state information measurement resource;iv) a physical uplink control channel format; andv) a list of carriers for said measurement of channel state information, carriers in said list of carriers belonging to at least two base stations or belonging to at least two sectors of said first base station; b) measuring, by said wireless device, said channel state information for each active carrier in said list of carriers on a plurality of OFDM subcarriers and a first plurality of subframes determined by a measurement resource based on said configuration; c) multiplexing and encoding said channel state measurement information based on said physical uplink control channel format; d) spreading by multiplying said multiplexed and encoded information by a sequence generated in said wireless device; e) transmitting said spread information employing single-carrier OFDM transmission on said channel state information transmission resource according to said channel state information transmission period; and f) simultaneously receiving signals from a subset of active carriers in said list of carriers, said signals carrying a plurality of data packets for said wireless device, carriers in said subset of carriers belonging to said at least two base stations or belonging to at least two sectors of said first base station. |
