Abstract:
1. A method in a network node for handling base sequences in a communication network, the network node being configured to communicate with a first user equipment, the network node comprising information about a default base sequence and an alternative base sequence, the method comprising: determining, for the first user equipment, that the alternative base sequence should replace the default base sequence; and sending information about the determined alternative base sequence to the first user equipment, wherein the information about the alternative base sequence is sent to the first user equipment via scheduling information or via radio resource control (RRC) signalling, in a scheduling grant, and includes: code points in a form of data bit values corresponding to specific cyclic shift/orthogonal cover code (CS/OCC) combinations for a demodulation reference signal (DMRS), an index of the alternative base sequence, or the alternative base sequence.
