Abstract
There is provided a method for transmitting a reference signal. The method for transmitting the reference signal includes: determining locations in time and frequency domains of a DRS, the DRS comprising at least one of a PSS, an SSS, a PBCH, a DMRS for PBCH, a CSI-RS for TRS, a CSI-RS for beam management, and a CSI-RS for acquiring channel state information; and transmitting the DRS at the locations in time and frequency domains of the DRS.
Claims18
A method for transmitting a reference signal, comprising:
- determining locations in time domain and frequency domain of a Discover Reference Signal (DRS), the DRS comprising at least one of a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), a Physical Broadcast Channel (PBCH), a Demodulation Reference Signal (DMRS) for PBCH, a Channel State Information Reference Signal (CSI-RS) for Tracking Reference Signal (TRS), a CSI-RS for beam management, and a CSI-RS for acquiring channel state information;
- and
- transmitting the DRS at the determined locations in time domain and frequency domain of the DRS,
- wherein the CSI-RS for TRS is located in at least one of a symbol with an index of 0 and a symbol with an index of 4 in a first time slot of a Synchronization Signal burst (SS burst);
- or
- the CSI-RS for TRS is located in a symbol with an index of 0 in a third time slot of a Synchronization Signal burst (SS burst);
- or
- the CSI-RS for TRS is located in a symbol with an index of 9 in a fourth time slot of a Synchronization Signal burst (SS burst).
A base station comprising a memory and a processor, the memory storing computer instructions, wherein the computer instructions cause the processor to:
- determine locations in time domain and frequency domain of a Discover Reference Signal (DRS), the DRS comprising at least one of a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), a Physical Broadcast Channel (PBCH), a Demodulation Reference Signal (DMRS) for PBCH, a Channel State Information Reference Signal (CSI-RS) for Tracking Reference Signal (TRS), a CSI-RS for beam management, and a CSI-RS for acquiring channel state information;
- and
- transmit the DRS at the determined locations in time domain and frequency domain of the DRS,
- wherein the CSI-RS for TRS is located in at least one of a symbol with an index of 0 and a symbol with an index of 4 in a first time slot of a Synchronization Signal burst (SS burst);
- or
- the CSI-RS for TRS is located in a symbol with an index of 0 in a third time slot of a Synchronization Signal burst (SS burst);
- or
- the CSI-RS for TRS is located in a symbol with an index of 9 in a fourth time slot of a Synchronization Signal burst (SS burst).
A non-transitory computer readable storage medium storing computer instructions, wherein the computer instructions cause a processor to:
- determine locations in time domain and frequency domain of a Discover Reference Signal (DRS), the DRS comprising at least one of a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), a Physical Broadcast Channel (PBCH), a Demodulation Reference Signal (DMRS) for PBCH, a Channel State Information Reference Signal (CSI-RS) for Tracking Reference Signal (TRS), a CSI-RS for beam management, and a CSI-RS for acquiring channel state information;
- and
- transmit the DRS at the determined locations in time domain and frequency domain of the DRS,
- wherein the CSI-RS for TRS is located in at least one of a symbol with an index of 0 and a symbol with an index of 4 in a first time slot of a Synchronization Signal burst (SS burst);
- or
- the CSI-RS for TRS is located in a symbol with an index of 0 in a third time slot of a Synchronization Signal burst (SS burst);
- or
- the CSI-RS for TRS is located in a symbol with an index of 9 in a fourth time slot of a Synchronization Signal burst (SS burst).
