Dynamic RxDiv for idle mode in a user equipment

A receiver, comprising:

• a plurality of receiver chains configured to interface with a plurality of antennas, respectively, and receive a plurality of signals therefrom, respectively;
• a reception quality estimation unit configured to determine a reception quality of a single active receiver chain of the plurality of receive chains when the receiver is in an idle mode, wherein the idle mode exists when no dedicated data channel (DCH), which carries user bits, exists for a data call;
• and
• a diversity controller configured to selectively activate at least a second receiver chain of the plurality of receiver chains in the idle mode based on the determined reception quality from the reception quality estimation unit.

A receiver, comprising:

• a plurality of receiver chains configured to interface with a plurality of antennas, respectively, and receive a plurality of signals therefrom, respectively;
• a diversity controller configured to selectively activate and deactivate one or more receiver chains of the plurality of receiver chains in an idle mode, wherein the idle mode exists when no dedicated data channel (DCH) connection exists for a data call;
• and
• a quality estimation unit configured to determine a reception quality of the receiver in the idle mode, wherein the diversity controller is configured to selectively activate and deactivate one or more receiver chains in the idle mode based on the determined reception quality.
