Abstract: A receiving device including a receiver configured to receive a communication signal (CS) in a current time frame, and a processor configured to determine a set of candidate Control Channels (CCHs), determine a decoding order for the candidate CCHs in the set, decode at least one candidate CCH in the set according to the decoding order, compute a possible Radio Network Temporary Identifier (RNTI) for the decoded candidate CCH, compute a metric value (MV) for the decoded candidate CCH, the MV provides an indication when the decoded candidate CCH might be an actual CCH, determine when the decoded candidate CCH is an actual CCH based on the computed possible RNTI and the MV, derive control information (CI) from the decoded candidate CCH when the decoded candidate CCH is determined as an actual CCH, and cancel or suppress interference in the CS based on the derived CI.

Abstract: The present invention relates to the field of communication technologies and discloses a method and an apparatus for auto gain control (AGC) in a radio receiver, which can ensure that a radio frequency device, an analog device, and various nodes in a digital domain are non-saturated and that useful signal power is adjusted to a certain power level. According to the present invention, total signal power on an air interface is subtracted from a preset first target power to obtain an analog auto gain control (AAGC) gain, and then a second target power is subtracted from an interference signal power in a digital baseband to obtain a digital auto gain control (DAGC) gain.
