US 12,317,201 B2 · Signal block reception with automatic gain control adjustment

Abstract

A method of signal block reception with automatic gain control (AGC) for a receiver is disclosed. The receiver is configured for at least a sleep mode and an active mode. The signal blocks are non-adjacent in time, and each signal block is configured to be received in entirety using a valid AGC setting determined based on a previous signal block. The method comprises, 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. Corresponding apparatus, receiver, wireless communication device and computer program product are also disclosed.

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.
