  • a once configured bit mapping via RRC i.e., how many slots to skip, periodicity of first SSSG, periodicity of second SSSG, will not be possible to be changed autonomously by the UE, since as repeatedly mentioned, triggering a RRC reconfiguration procedure is required.

  • An approach using a periodic monitoring pattern may thus include (see also Figure 5):
  • a single "large” PDCCH skipping duration (i.e., 8 slots) to be used in between the DL frame arrival intervals.

This will require a new RRC reconfiguration message to adapt the PDCCH monitoring adaptation procedure to the new traffic period respectively frame rate, hence resulting in increased delay (about 5-6 frames will be lost) and increased power consumption.
