Abstract
Methods and apparatuses in a wireless communication system. A base station (BS) includes a transceiver and a processor. The processor is configured to receive, via the transceiver, a channel state information (CSI) report from at least one user equipment (UE). The processor is also configured to configure CSI-reference signal (RS) resources for the at least one UE. The processor is further configured to, based on the CSI report from the at least one UE, perform one of: set a transmission power to full power for transmission in a physical downlink shared channel (PDSCH); or apply a back-off percentage to the transmission power in the PDSCH.
Claims27
A base station (BS) in a wireless communication system, the BS comprising:
- a transceiver;
- and
- a processor configured to:
- receive, via the transceiver, a channel state information (CSI) report from at least one user equipment (UE);
- configure CSI—reference signal (RS) resources for at least one user equipment (UE);
- and
- based on the CSI report from the at least one UE and a classification including a layer of the at least one UE to receive multiple beams, perform one of operations to:
- set a transmission power to full power for a physical downlink shared channel (PDSCH) transmission;
- or
- apply a back-off percentage to the transmission power in the PDSCH transmission, wherein the classification is determined based on an achievable rate comprising a first achievable rate associated with a first CSI-RS report and a second achievable rate associated with a second CSI-RS report that are compared to identify a level of power in the PDSCH transmission.
A method of a base station (BS), the method comprising:
- receiving, via a transceiver, a channel state information (CSI) report from at least one user equipment (UE);
- configuring CSI—reference signal (RS) resources for the at least one UE;
- and
- based on the CSI report from the at least one UE and a classification including a layer of the at least one UE to receive multiple beams, performing one of:
- setting a transmission power to full power for a physical downlink shared channel (PDSCH) transmission;
- or
- applying a back-off percentage to the transmission power in the PDSCH transmission, wherein the classification is determined based on an achievable rate comprising a first achievable rate associated with a first CSI-RS report and a second achievable rate associated with a second CSI-RS report that are compared to identify a level of power in the PDSCH transmission.
A non-transitory computer readable medium comprising instructions that, when executed by at least one processor, cause the at least one processor to:
- receive a channel state information (CSI) report from at least one user equipment (UE);
- configure CSI—reference signal (RS) resources for the at least one UE;
- and
- based on the CSI report from the at least one UE and a classification including a layer of the at least one UE to receive multiple beams, perform one of operations to:
- set a transmission power to full power for a physical downlink shared channel (PDSCH) transmission;
- or
- apply a back-off percentage to the transmission power in the PDSCH transmission, wherein the classification is determined based on an achievable rate comprising a first achievable rate associated with a first CSI-RS report and a second achievable rate associated with a second CSI-RS report that are compared to obtain to identify a level of power in the PDSCH transmission.
