Receive antenna selection/combining of receive antennas using fewer number of receive chains

A method for wireless communications, comprising:

• communicating with a user equipment (UE) that utilizes a first set of one or more receive antennas during a normal operational period;
• and
• configuring the UE with measurement gaps for performing receive antenna diversity measurements with a second set of one or more receive antennas.

An apparatus for wireless communications, comprising:

• means for communicating with a user equipment (UE) that utilizes a first set of one or more receive antennas during a normal operational period;
• and
• means for configuring the UE with measurement gaps for performing receive antenna diversity measurements with a second set of one or more receive antennas.

A computer-program product for wireless communications by a first device, comprising a computer-readable medium having instructions stored thereon, the instructions being executable by one or more processors and the instructions comprising:

• instructions for communicating with a user equipment (UE) that utilizes a first set of one or more receive antennas during a normal operational period;
• and
• instructions for configuring the UE with measurement gaps for performing receive antenna diversity measurements with a second set of one or more receive antennas.

An apparatus for wireless communications, comprising at least one processor configured to:

• communicate with a user equipment (UE) that utilizes a first set of one or more receive antennas during a normal operational period;
• and
• configure the UE with measurement gaps for performing receive antenna diversity measurements with a second set of one or more receive antennas.

A method for wireless communications, comprising:

• communicating with a serving base station of a serving cell;
• and
• performing measurements for the serving cell and neighboring cells on a carrier frequency using different sets of receive antennas at different times.
