Method and system for notification of scrambling code identification signalling group

摘要

Disclosed in the present disclosure is a method for notification of scrambling code identification signalling group, and the present disclosure comprises: a network side transmits a scrambling code identification signalling group to a receiver; the receiver generates a corresponding scrambling code sequence of a demodulation pilot according to the scrambling code identification signalling group, generates a pilot symbol sequence according to the scrambling code sequence of the demodulation pilot, and performs channel estimation according to the pilot symbol sequence. The present disclosure also provides a system for implementing the notification of scrambling code identification signalling group. According to the technical solution in the disclosure, the receiver can obtain, according to the scrambling code identification signalling group transmitted from the network side, the scrambling code sequence of the demodulation reference signal and/or demodulation pilot which is the same as that of the network side, and thus interference can be avoided.

1. A method for notification of scrambling code identification signalling group, wherein the method comprises:
receiving, by a receiver, a scrambling code identification signalling group; wherein the scrambling code identification signalling group comprises at least one of the following: a virtual identification signalling, a virtual identification enabling signalling of one bit, and a virtual identification index signalling of one or more bits, where the virtual identification signalling includes one or more virtual cell identifications; and the method further comprises: receiving, by the receiver, the virtual identification signalling via a System Information Block (SIB) or a Radio Resource Control (RRC) signalling, and storing, by the receiver, the virtual identification signalling in the received SIB or RRC signalling; performing blind detection for Downlink Control Information (DCI); wherein the virtual identification index signalling is carried in DCI Format 2B or DCI Format 2C or a future format of the DCI; obtaining the virtual identification index signalling according to the blind detection, and determining the virtual identification signalling according to the corresponding virtual identification index signalling; generating, by the receiver, a corresponding scrambling code sequence of a demodulation pilot according to the determined virtual identification signalling; generating a pilot symbol sequence according to the scrambling code sequence of the demodulation pilot; and performing channel estimation according to the pilot symbol sequence.
