Abstract
Embodiments of the present disclosure relate to methods and devices for reference signal (RS) transmission. In example embodiments, a method implemented in a network device is provided. According to the method, a first set of RS resources are determined for RS transmission by the network device. The first set of RS resources are associated with a first number of RS ports to be used for RS transmission and correspond to a first set of resource elements (REs) interpolated with unused REs in frequency domain. A first RS configuration for RS transmission is generated based on the first set of RS resources. Information on the first RS configuration is transmitted to a terminal device served by the network device.

-42. (canceled)
A method performed by a User Equipment (UE), the method comprising:
- performing a measurement of a CSI-RS (Channel State Information Reference Signal);
- and
- transmitting a Sounding Reference Signal (SRS) associated with the CSI-RS, based on the measurement.
A method performed by a base station, the method comprising:
- transmitting a CSI-RS (Channel State Information Reference Signal) to a User Equipment (UE);
- and
- receiving a Sounding Reference Signal (SRS) associated with the CSI-RS, based on a measurement of the CSI-RS performed by the UE.
A User Equipment (UE) comprising:
- a controller configured to perform a measurement of a CSI-RS (Channel State Information Reference Signal);
- and
- a transceiver configured to transmit a Sounding Reference Signal (SRS) associated with the CSI-RS, based on the measurement.
