Abstract
A method for operating a user equipment (UE) comprises receiving configuration information about a channel state information (CSI) report, the configuration information including information about a number M denoting a number of frequency domain basis vectors; identifying a value of M; determining, based on the value of M, a frequency granularity of the CSI report from wideband (WB) and subband (SB); determining the CSI report according to the frequency granularity; and transmitting the CSI report.
Claims17
A user equipment (UE) comprising:
- a transceiver configured to receive configuration information about a channel state information (CSI) report, the configuration information including information about a number M denoting a number of frequency domain basis vectors;
- and
- a processor operably coupled to the transceiver, the processor, based on the configuration information, configured to:
- identify a value of M,
- determine, based on the value of M, a frequency granularity of the CSI report from wideband (WB) and subband (SB), wherein the frequency granularity of the CSI report=WB when M=1, and
- determine the CSI report according to the frequency granularity;
- wherein the transceiver is further configured to transmit the CSI report.
A base station (BS) comprising:
- a processor configured to generate configuration information about a channel state information (CSI) report, the configuration information including information about a number M denoting a number of frequency domain basis vectors;
- and
- a transceiver operably coupled to the processor, the transceiver configured to:
- transmit the configuration information about the CSI report, and
- receive the CSI report;
- wherein a frequency granularity of the CSI report is determined from wideband (WB) and subband (SB) based on a value of M, wherein the frequency granularity of the CSI report=WB when M=1.
A method for operating a user equipment (UE), the method comprising:
- receiving configuration information about a channel state information (CSI) report, the configuration information including information about a number M denoting a number of frequency domain basis vectors;
- identifying a value of M;
- determining, based on the value of M, a frequency granularity of the CSI report from wideband (WB) and subband (SB), wherein the frequency granularity of the CSI report=WB when M=1;
- determining the CSI report according to the frequency granularity;
- and
- transmitting the CSI report.
