CA2642024A1 - Method and apparatus for sending signaling information via channel ids - Google Patents

Abstract

Techniques for sending signaling information are described. Multiple signaling channels may be available to send signaling information. Different signaling information, different signaling parameter values, or different interpretations of signaling parameter values may be associated with different signaling channels and conveyed by the selection of these signaling channels, which may be used for actual transmission of remaining signaling information. A transmitter selects at least one signaling channel from among the multiple signaling channels based on first signaling information and sends second signaling information on the selected signaling channel(s) to convey the first and second signaling information. The transmitter sends at least one data stream on at least one data channel in accordance with the first and second signaling information. A receiver obtains the first signaling information based on the selected signaling channel(s) and decodes the selected signaling channel(s) to obtain the second signaling information. The receiver processes the data channel(s) in accordance with the first and second signaling information to recover the data stream(s).
