摘要： A method of wireless data communication. The method includes the step of receiving a feedback indicator signal at two or more points in space from two or more transmission paths. Each transmission path may correspond with a wireless unit seeking to communicate over a downlink and/or an uplink. The method, thereafter, includes the step of measuring a relative phase difference between the feedback indicator signals of two or more transmission paths. Subsequently, one spreading code may be assigned to two or more transmission paths if the measured relative phase difference between their feedback indicator signals corresponds with minimal mutual interference. Consequently, two or more wireless units having a measured relative phase difference in the range of about 90 degrees and about 270 degrees, for example, may use the at least of the same spreading codes.

摘要： Enhanced physical downlink control channel are multiplexed with physical downlink data channel in frequency division multiplexing (FDM), or in frequency division multiplexing (FDM)+time division multiplexing (TDM). FDM mode applies to users that have only UL grants in that subframe. UL grants of different users are cross-interleaved and transmitted over the entire physical resource blocks (both slots) in FDM. Frequency resources for cross-interleaved UL grants are distributed. TDM+FDM applies to users that have both DL and UL grants, or have only DL grant in that subframe. DL/UL grant (maybe mixed) is transmitted only in the first slot of physical resource blocks in TDM+FDM, where the second slots in those resource blocks can be used for those users' downlink data transmission.
