Abstract
An apparatus and method for transmitting and receiving a signal in a Distributed Antenna System (DAS) is provided. A method for determining an initial state in a DAS includes receiving a value through high-level signalling and determining an initial state based on the value, in which the value includes a value in which is set an initial state of a scrambling sequence, which differs according to a transmission point.
Claims6
A method for determining an initial state of a scrambling sequence in a distributed antenna system comprising a plurality of transmission points, the method comprising:
- receiving a value through high-level signalling;
- and
- determining an initial state of the scrambling sequence related to a reference signal as one of a legacy initial state and a new initial state, based on the value,
- wherein the initial state of the scrambling sequence is determined based on a transmission point that transmits the reference signal,
- wherein the value is related to the plurality of transmission points sharing the same cell identifier, and
- wherein the initial state is determined based on at least two of a position of an antenna port, a number of antenna ports, and an antenna pattern for the antenna port.
An apparatus for determining an initial state of a scrambling sequence in a distributed antenna system comprising a plurality of transmission points, the apparatus comprising:
- a receiver configured to receive a value through high-level signalling;
- and
- a controller configured to determine an initial state of the scrambling sequence related to a reference signal as one of a legacy initial state and a new initial state, based on the value,
- wherein the initial state of the scrambling sequence is determined based on a transmission point that transmits the reference signal,
- wherein the value is related to the plurality of transmission points sharing the same cell identifier, and
- wherein the initial state is determined based on at least two of a position of an antenna port, a number of antenna ports, and an antenna pattern for the antenna port.
