Abstract
An apparatus and method for transmitting reference signal and a communication system. The method includes: transmitting first information on one or more beams formed by a plurality of antennas in beam sweeping duration, the first information at least comprising a synchronization channel, a first reference signal and a physical broadcast channel. Hence, a receiving device may demodulate the physical broadcast channel by using the first reference signal, thereby achieving design of beam reference signals in a beam sweeping system.
Claims18
An apparatus for transmitting a reference signal, configured in a transmitting device, the apparatus comprising:
- a memory that stores a plurality of instructions;
- and
- a processor coupled to the memory and configured to execute the plurality of instructions to:
- periodically transmit first information on at least one beam, the first information at least comprising a primary synchronization signal, a secondary synchronization signal, a physical broadcast channel and a first reference signal for demodulating the physical broadcast channel, and the first reference signal is frequency-multiplexed with the physical broadcast channel,
- wherein the first reference signal is generated based on a beam identifier and a cell ID, and
- a pseudo random sequence of the first reference signal for demodulating the physical broadcast channel is initialized based on the beam identifier and the cell ID.
An apparatus for transmitting a reference signal, configured in a receiving device, the apparatus comprising:
- a memory that stores a plurality of instructions;
- and
- a processor coupled to the memory and configured to execute the plurality of instructions to:
- receive first information periodically transmitted on at least one beam, the first information at least comprising a primary synchronization signal, a secondary synchronization signal, a physical broadcast channel and a first reference signal for demodulating the physical broadcast channel, and the first reference signal is frequency-multiplexed with the physical broadcast channel,
- wherein the first reference signal is generated based on a beam identifier and a cell ID, and
