Radio receiver for carrier aggregation
First Claim
1. A radio receiver circuit configured to operate in a carrier-aggregation (CA) mode, wherein the radio receiver circuit is to receive a plurality of component carriers (CCs) and in a non-CA mode, wherein the radio receiver circuit is to receive a single CC, comprising:
- a first receive path arranged to be operatively connected to an antenna;
a second receive path arranged to be operatively connected to the same antenna; and
a processing circuit operatively connected to the first receive path and the second receive path;
whereinthe processing circuit is adapted to, in the CA mode, control the first receive path to receive a first CC of said plurality of CCs and control the second receive path to receive a second CC, separate from the first CC, of said plurality of CCs; and
the processing circuit is adapted to, in the non-CA mode, selectively control the first receive path and the second receive path to both receive the same single CC.

Abstract
A radio receiver circuit (10) configurable to operate in a carrier-aggregation, CA, mode and in a non-CA mode is disclosed. It comprises a first receive path (30) arranged to be operatively connected to an antenna (15) and a second receive path (40) arranged to be operatively connected to the same antenna (15). It further comprises a control unit (50) operatively connected to the first receive path (30) and the second receive path (40). In the CA mode, the control unit (50) controls the first receive path (30) to receive a first CC (6) and the second receive path to receive a second CC (8). In the non-CA mode, the control unit (50) selectively controls the first receive path (30) and the second receive path (40) to both receive the same single CC (6).

16. A method of operating a radio receiver circuit configurable to operate in a carrier-aggregation (CA) mode, wherein the radio receiver circuit is to receive a plurality component carriers (CCs) and in a non-CA mode, wherein the radio receiver circuit is to receive a single frequency CC, wherein the radio receiver circuit comprises:
-
a first receive path operatively connected to an antenna; a second receive path operatively connected to the same antenna; and a processing circuit operatively connected to the first receive path and the second receive path;
whereinthe method comprises controlling, in the CA mode and by the processing circuit, the first receive path to receive a first CC of said plurality of frequency bands and the second receive path to receive a second CC, separate from the first CC, of said plurality of CCs; and selectively controlling, in the non-CA mode and by the processing circuit, the first receive path and the second receive path to both receive the same single CC.

17. A non-transitory computer-readable medium comprising, stored thereupon, a computer program product comprising computer program code that, when executed by a processing circuit of a radio receiver circuit configured to operate in a carrier-aggregation (CA) mode, wherein the radio receiver circuit is to receive a plurality component carriers (CCs) and in a non-CA mode, wherein the radio receiver circuit is to receive a single frequency CC, wherein the radio receiver circuit comprises a first receive path arranged to be operatively connected to an antenna, a second receive path arranged to be operatively connected to the same antenna, and the processing circuit operatively connected to the first receive path and the second receive path, causes the processing circuit to:
-
in the CA mode, control the first receive path to receive a first CC of said plurality of CCs and control the second receive path to receive a second CC, separate from the first CC, of said plurality of CCs; and in the non-CA mode, selectively control the first receive path and the second receive path to both receive the same single CC.
