Methods and apparatus for cell global identifier reading in new radio system

An apparatus, comprising processing circuitry configured to:

• receive a request over a serving cell to report Cell Global Identifier (CGI) information of a target cell to a network node;
• decode system information to acquire the CGI information of the target cell by:
• using Synchronization Signal Block (SSB) and Remaining Minimum System Information (RMSI) occasions in Discontinuous Reception (DRX) off duration of the serving cell;
• using at least one autonomous gap in data reception and transmission of the serving cell;
• or
• using at least one specific gap to interrupt data reception and transmission in DRX on durations of the serving cell;
• and
• transmit the CGI information of the target cell to the network node.

A non-transitory computer readable medium storing instructions which, when executed by a processor, cause the processor to perform the steps of:

• receiving a request over a serving cell to report Cell Global Identifier (CGI) information of a target cell to a network node;
• decoding system information to acquire the CGI information of the target cell by:
• using Synchronization Signal Block (SSB) and Remaining Minimum System Information (RMSI) occasions in Discontinuous Reception (DRX) off durations of the serving cell;
• using at least one autonomous gap in data reception and transmission of the serving cell;
• or
• using at least one specific gap to interrupt data reception and transmission in DRX on durations of the serving cell;
• and
• transmitting the CGI information of the target cell to the network node.
