Method and apparatus for beam measurement and reporting
Methods and apparatuses for beam measurement and reporting. A method for operating a user equipment (UE) includes receiving information about a report, the report including at least one capability value about an uplink (UL) transmission; determining the at least one capability value; determining the report including an indicator indicating the at least one capability value; and transmitting the report.
1 . A user equipment (UE) comprising:
a transceiver configured to:
transmit, to a base station, capability information including a list of capability values, wherein the list of capability values indicates a maximum number of sounding reference signal (SRS) antenna ports of the UE, and receive, from the base station, configuration information on a channel state information (CSI) report; and
a processor operably coupled to the transceiver, the processor configured to identify a capability value from the list of capability values,
wherein the transceiver is further configured to transmit, to the base station, the CSI report including a resource indicator and an index of the identified capability value, and
wherein the index is associated with the resource indicator.
2 . The UE of claim 1 , wherein
the resource indicator is a channel state information reference signal resource indicator (CRI) or a synchronization signal block (SSB) resource indicator (SSBRI).
3 . The UE of claim 1 , wherein:
the list of supported capability values includes values of {1,2,4}, and
a bit width for the index is 2 bits.
4 . The UE of claim 1 , wherein the CSI report further includes a value of a layer-1 signal to interference and noise ratio (L1-SINR) or a value of a layer-1 reference signal received power (L1-RSRP) for the resource indicator.
5 . A base station (BS) comprising:
a processor; and
a transceiver operably coupled to the processor, the transceiver configured to:
receive, from a user equipment (UE), capability information including a list of capability values, wherein the list of capability values indicates a maximum number of sounding reference signal (SRS) antenna ports of the UE,
transmit, to the UE, configuration information on a channel state information (CSI) report, and
receive, from the UE, the CSI report including a resource indicator and an index of an identified capability value of the capability values, the index being associated with the resource indicator.
6 . The BS of claim 5 , wherein
the resource indicator is a channel state information reference signal resource indicator (CRI) or a synchronization signal block (SSB) resource indicator (SSBRI).
7 . The BS of claim 5 , wherein:
the list of supported capability values includes values of {1,2,4}, and
a bit width for the index is 2 bits.
8 . The BS of claim 5 , wherein the CSI report further includes a value of a layer-1 signal to interference and noise ratio (L1-SINR) or a value of a layer-1 reference signal received power (L1-RSRP) for the resource indicator.
9 . A method performed by a user equipment (UE), the method comprising:
transmitting, to a base station, capability information including a list of capability values, wherein the list of capability values indicates a maximum number of sounding reference signal (SRS) antenna ports of the UE;
receiving, from the base station, configuration information on a channel state information (CSI) report;
identifying a capability value from the list of capability values; and
transmitting the CSI report including a resource indicator and an index of the identified capability value, the index being associated with the resource indicator.
10 . The method of claim 9 , wherein
the resource indicator is a channel state information reference signal resource indicator (CRI) or a synchronization signal block (SSB) resource indicator (SSBRI).
11 . The method of claim 9 , wherein:
the list of supported capability values includes values of {1,2,4}, and
a bit width for the index is 2 bits.
12 . The method of claim 9 , wherein the CSI report further includes a value of a layer-1 signal to interference and noise ratio (L1-SINR) or a value of a layer-1 reference signal received power (L1-RSRP) for the resource indicator.
