Abstract
A method for operating a user equipment (UE) comprises receiving information about a channel state information (CSI) report, the information including information about a parameter α, wherein the parameter α is a rational number≤1; determining a value of K1 based on the parameter α; selecting K1 CSI reference signal (CSI-RS) ports from a total of P CSI-RS ports; determining the CSI report including an indicator indicating the selected K1 CSI-RS ports; and transmitting the CSI report including the indicator indicating the selected K1 CSI-RS ports.
Claims20
A user equipment (UE) comprising:
- a transceiver configured to receive information on P channel state information-reference signal (CSI-RS) ports and information on a parameter γ, wherein the parameter γ is a value among a set of values;
- and
- a processor operably coupled to the transceiver, the processor, based on the information, configured to:
- determine a value of Yv based on the parameter γ;
- select Yv CSI-RS ports from the P CSI-RS ports;
- and
- determine a CSI report including an indicator indicating the selected Yv CSI-RS ports,
- wherein the transceiver is configured to transmit the CSI report including the indicator indicating the selected Yv CSI-RS ports.
A base station (BS) comprising:
- a processor configured to determine information on P channel state information-reference signal (CSI-RS) ports and information on a parameter γ, wherein the parameter γ is a value among a set of values;
- and
- a transceiver operably coupled to the processor, the transceiver configured to:
- transmit the information on the P CSI-RS ports and the parameter γ;
- and
- receive a CSI report including an indicator indicating Yv CSI-RS ports,
- wherein:
- the Yv CSI-RS ports are among the P CSI-RS ports, and
- the value of Yv is based on the parameter γ.
