Method for reporting channel status and device

A method for reporting a channel status, the method comprising:

• receiving, by a user equipment (UE), configuration signaling from a base station, wherein the configuration signaling comprises a reporting period of channel state information (CSI), and wherein the configuration signaling is signaling for semi-persistently reporting the CSI;
• receiving, by the UE, channel status request signaling scrambled by a dedicated channel state information-radio network temporary identifier (CSI-RNTI) from the base station for instructing the UE to report the CSI, wherein the channel status request signaling comprises a physical resource block (PRB) and a modulation and coding scheme for reporting the CSI;
• and
• transmitting, by the UE to the base station according to the reporting period, the CSI, wherein the CSI is transmitted on the PRB using the modulation and coding scheme.

A base station, comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium coupled to the processor and storing programming instructions which, when executed by the processor, instruct the processor to:
• transmit configuration signaling to a user equipment (UE), wherein the configuration signaling comprises a reporting period of channel state information (CSI), and wherein the configuration signaling is signaling for semi-persistently reporting the CSI;
• transmit channel status request signaling scrambled by a dedicated channel state information-radio network temporary identifier (CSI-RNTI) to the UE for instructing the UE to report the CSI, wherein the channel status request signaling comprises a physical resource block (PRB) and a modulation and coding scheme for reporting the CSI;
• and
• receive the CSI, wherein the CSI is transmitted according to the reporting period, on the PRB, and using the modulation and coding scheme.

A device, comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium coupled to the processor and storing programming instructions which, when executed by the processor, instruct the processor to:
• receive configuration signaling e from a base station, wherein the configuration signaling comprises a reporting period of channel state information (CSI), and wherein the configuration signaling is signaling for semi-persistently reporting the CSI;
• receive channel status request signaling scrambled by a dedicated channel state information-radio network temporary identifier (CSI-RNTI) from the base station for instructing the device to report the CSI, wherein the channel status request signaling comprises a physical resource block (PRB) and a modulation and coding scheme for reporting the CSI;
• and
• transmit, to the base station according to the reporting period, the CSI, wherein the CSI is transmitted on the PRB using the modulation and coding scheme.
