METHOD AND ARRANGEMENT FOR MITIGATING INTER -CELL INTERFERENCE ON TRANSMISSION OF UPLINK CONTROL INFORMATION

摘要

In various embodiments, a method for transmitting uplink control information in a cell is provided. The uplink control information is transmitted during a time slot. According to this method, bits corresponding to uplink control information are mapped (1810) to complex modulation symbols. The complex modulation symbols are spread (1820) in the time slot using a set of orthogonal cover code, OCC, sequences, such that at least two of the complex modulation symbols are spread using different OCC sequences. The uplink control information is then transmitted (1830) using said spread complex modulation symbols.
