Abstract
A method for operating a user equipment (UE) comprises receiving information about a channel state information (C SI) report, the information including a number NRRH>1 and RRH r, wherein: NRRH=number of remote radio heads (RRHs), RRH r comprises a group of P channel state information reference signal (C SIRS) antenna ports, and r=1, . . . , NRRH; selecting a strongest RRH from the NRRH RRHs; determining the CSI report including an indicator indicating the strongest RRH; and transmitting the CSI report including the indicator indicating the strongest RRH.
Claims20
A user equipment (UE) comprising:
- a transceiver configured to receive information about a channel state information (CSI) report, the information including a number NRRH>1 and RRH r, wherein:
- NRRH=number of remote radio heads (RRHs),
- RRH r comprises a group of PCSIRS,r channel state information reference signal (CSIRS) antenna ports, and
- r=1, . . . , NRRH;
- and
- a processor operably coupled to the transceiver, the processor, based on the information, configured to:
- select a strongest RRH from the NRRH RRHs;
- and
- determine the CSI report including an indicator indicating the strongest RRH;
- wherein the transceiver is configured to transmit the CSI report including the indicator indicating the strongest RRH.
A base station (BS) comprising:
- a processor configured to generate information about a channel state information (CSI) report, the information including a number NRRH>1 and RRH r, wherein:
- NRRH=number of remote radio heads (RRHs),
- RRH r comprises a group of PCSIRS,r channel state information reference signal (CSIRS) antenna ports, and
- r=1, . .. , NRRH;
- and
- a transceiver operably coupled to the processor, the transceiver configured to:
- transmit the information;
- and
- receive the CSI report,
- wherein the CSI report includes an indicator indicating a strongest RRH selected from the NRRH RRHs.
