1. A method for a receiver apparatus configured with at least a sleep mode and an active mode, wherein the receiver apparatus is further configured to receive signal blocks that are non-adjacent and to receive each signal block in its entirety based on a valid automatic gain control (AGC) setting determined based on a previous signal block, the method comprising:
when switching from the sleep mode to the active mode for continuous reception of a signal block:
receiving a first set of samples of the signal block;
determining an applicable AGC setting based on the first set of samples of the signal block; and
receiving a second set of samples of the signal block using the applicable AGC setting determined based on the first set of samples, wherein receiving the second set of samples comprises:
determining an updated applicable AGC setting based on a first part of the second set of samples of the signal block; and
receiving a second part of the second set of samples of the signal block using the updated applicable AGC setting.
