Abstract
Systems, methods, and circuitries are provided for configuring and indicating channel state information resource signals (CSI-RS) using discovery reference signal (DRS) resources. An example method includes determining discovery reference signal (DRS) resources for use in carrying channel state information reference signals (CSI-RS); generating CSI-RS configuration information that defines at least one CSI-RS using the DRS resources; and signaling the CSI-RS configuration information to a user equipment (UE) device.
Claims20
A baseband processor, configured to perform operations comprising:
- determining discovery reference signal (DRS) resources for use in carrying channel state information reference signals (CSI-RS);
- generating CSI-RS configuration information that defines at least one CSI-RS using the DRS resources;
- and
- instructing a transceiver to signal the CSI-RS configuration information to a user equipment (UE).
A method, comprising with a network (NW) node in a wireless network:
- determining discovery reference signal (DRS) resources for use in carrying channel state information reference signals (CSI-RS);
- generating CSI-RS configuration information that defines at least one CSI-RS using the DRS resources;
- and
- signaling the CSI-RS configuration information to a user equipment (UE).
A user equipment (UE), comprising a memory and one or more processors configured to, when executing instructions stored in the memory, cause the UE to:
- receive, from a network (NW) node, channel state information reference signal (CSI-RS) configuration information that defines at least one CSI-RS using discovery reference signal (DRS) resources;
- monitor the DRS resources for the CSI-RS;
- measure CSI-RS received on the DRS resources to generate CSI information;
- and
- transmit the CSI information to the NW node.
