Abstract
Techniques are described to indicate reference signal port. An example wireless communication method includes determining, by a communication device, a demodulation reference signal (DMRS) port and at least one type of an orthogonal code; and receiving, by the communication device at the DMRS port, a DMRS based on the at least one type of the orthogonal code.

A wireless communication method, comprising:
- determining, by a communication device, a demodulation reference signal (DMRS) port and at least one type of an orthogonal code,
- wherein the at least one type of the orthogonal code is determined based on an indication of the DMRS port received by the communication device,
- wherein DMRS ports with different types of frequency division orthogonal cover code (FD-OCC) are mapped on resources in one physical resource block (PRB) in frequency domain, and
- wherein the DMRS ports with different types of FD-OCC include the received DMRS port;
- and
- receiving, by the communication device at the DMRS port, a DMRS based on the at least one type of the orthogonal code.
