1. A method for generating control information for use in transmission of a data stream to a wireless receiver device, the method comprising:

  • generating first control information, wherein the first control information is for configuring the receiver device to decode a wirelessly received data stream, wherein the first control information is generated according to a first protocol version parameter and a first physical layer parameter;

    generating first data, wherein the first data includes said first protocol version parameter and said first physical layer parameter indicating a physical layer structure of the first control information;

    transmitting the first control information, the first data, and a first plurality of packets that include information specifying at least one data stream;

    generating second control information, wherein the second control information is for configuring the receiver device to decode a data stream, wherein the second control information is generated according to a second protocol version parameter and a second physical layer parameter indicating a physical layer structure of the second control information;

    generating second data, wherein the second data includes said second protocol version parameter and said second physical layer parameter indicating a structure of the second control information, wherein a value of said second physical layer parameter is different than a value of said first physical layer parameter, and wherein the physical layer structure of the second control information is different than the physical layer structure of the first control information; and

    transmitting the second control information, the second data, and a second plurality of packets that include information specifying at least one data stream.
