Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network entity, information associated with a virtual resource block to physical resource block (VRB-to-PRB) mapping for a demodulation reference signal (DMRS). The UE may receive, from the network entity, an indication to apply a frequency domain orthogonal cover code (FD-OCC) to the DMRS for every three resource elements or every six resource elements of the DMRS. The indication may relate to a DMRS configuration type that uses every other resource element within one or more symbols allocated to the DMRS. Numerous other aspects are described.
Claims30
An apparatus for wireless communication at a user equipment (UE), comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured individually or collectively to:
- transmit, to a network entity, information associated with a virtual resource block to physical resource block (VRB-to-PRB) mapping for a demodulation reference signal (DMRS);
- and
- receive, from the network entity, an indication to apply a frequency domain orthogonal cover code (FD-OCC) to the DMRS for every three resource elements of the DMRS or every six resource elements of the DMRS.
A method of wireless communication performed by a user equipment (UE), comprising:
- transmitting, to a network entity, information associated with a virtual resource block to physical resource block (VRB-to-PRB) mapping for a demodulation reference signal (DMRS);
- and
- receiving, from the network entity, an indication to apply a frequency domain orthogonal cover code (FD-OCC) to the DMRS for every three resource elements of the DMRS or every six resource elements of the DMRS.
A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:
- one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
- transmit, to a network entity, information associated with a virtual resource block to physical resource block (VRB-to-PRB) mapping for a demodulation reference signal (DMRS);
- and
- receive, from the network entity, an indication to apply a frequency domain orthogonal cover code (FD-OCC) to the DMRS for every three resource elements of the DMRS or every six resource elements of the DMRS.
An apparatus for wireless communication, comprising:
- means for transmitting, to a network entity, information associated with a virtual resource block to physical resource block (VRB-to-PRB) mapping for a demodulation reference signal (DMRS);
- and
- means for receiving, from the network entity, an indication to apply a frequency domain orthogonal cover code (FD-OCC) to the DMRS for every three resource elements of the DMRS or every six resource elements of the DMRS.
