Method and apparatus for walsh space assignment in a communication system

A method of Walsh space assignment comprising:

• computing a Walsh space indicator configured as a single number identifying a plurality of Walsh functions forming a sub-space of Walsh space to be used for particular transmissions by specifying a number of Walsh functions, for use in data demodulation of the particular transmissions, from a programmed list of Walsh functions;
• and
• continuously transmitting the Walsh space indicator from a base station to one or more mobile stations.

A method of Walsh space assignment comprising signaling a request for transmission of Walsh space information identifying an overall Walsh space configured for a Walsh space indicator configured as a single number to identify a plurality of Walsh functions forming a sub-space of the Walsh space to be used for particular transmissions by specifying a quantity of Walsh functions, for use in demodulation of the particular transmissions, from a programmed list of Walsh functions.

A method for receiving a Walsh indicator channel, including a Walsh space indicator, periodically transmitted from a base station, comprising decoding the Walsh indicator channel to detect a Walsh space indicator configured as a single number identifying a plurality of Walsh functions forming a sub-space of the Walsh space to be used for particular transmissions by specifying a quantity of Walsh functions, for use in demodulation of the particular transmissions, from a programmed list of Walsh functions.

A method for data communication, in a system including a base station transmitting a control channel and a periodically transmitted Walsh indicator channel, including a Walsh space indicator, comprising:

• decoding a first period of the Walsh indicator channel to detect the Walsh space indicator configured as a single number identifying a plurality of Walsh functions forming a sub-space of Walsh space to be used for particular transmissions by specifying a quantity of Walsh functions, for use in demodulation of the particular transmissions, from a programmed list of Walsh functions.
