1. A method of allocating receive chains among base stations in a wireless network, the method comprising:

  • determining a total number of receive chains RT available in a receiver subsystem of a wireless communication device;

    determining a total number of synthesizers ST in the receiver subsystem;

    determining a number of receive chains NS, out of the total number of receive chains RT, that are needed to receive a signal from a currently serving base station; and

    comparing RT against NS, wherein;

    if RT is not greater than NS, then tuning the RT receive chains to a channel of the currently serving base station, andif RT is greater than NS, then;

    identifying, from the total number of receive chains RT, which receive chains NS are to process signals from the currently serving base station;

    tuning the receive chains NS to the channel of the currently serving base station; and

    tuning a remaining number of the total number of receive chains RT to different channels to make measurements of signals of at least some of the other base stations.
