System and method for reducing interference generated by a CDMA communications device

A method for reducing interference generated by a communication device which nominally transmits data at a variable rate and which nominally varies transmit power in response to said variable rate, said method comprising the steps of:

• directing said communication device to continuously transmit RF energy at a full rate power level irrespective of said variable rate;
• and
• transmitting, from said communication device and in response to said directing step, RF energy continuously at said full rate power level irrespective of said variable rate, whereby said interference is reduced proximate said communication device due to continuous transmission thereby at said full rate power level;
• wherein said communication device nominally transmits non-full frames of data containing a variable number of bits in response to said variable rate, and wherein said transmitting step further comprises the steps of:
• generating full frames of data containing a fixed number of bits irrespective of said variable rate;
• and
• transmitting said full frames of data at said full-rate power level;
• and
• wherein said communication device nominally distributes said variable number of bits pseudo-randomly in said non-full frames of data, and wherein said full frames of data generated by said controller contain a variable number of padding bits having a predetermined pattern.

A communication device which nominally transmits data at a variable rate and which nominally varies transmit power in response to said variable rate, said system comprising:

• a transmitter;
• and
• a controller for directing said transmitter to transmit RF energy continuously at a full rate power level irrespective of said variable rate, whereby said interference is reduced proximate said communication device due to continuous transmission thereby at said full rate power level;
• wherein said communication device nominally transmits non-full frames of data containing a variable number of bits in response to said variable rate, and wherein said controller generates full frames of data containing a fixed number of bits irrespective of said variable rate and wherein said transmitter transmits said full frames of data at said full-rate power level;
• and
• wherein said communication device nominally distributes said variable number of bits pseudo-randomly in said non-full frames of data, and wherein said full frames of data generated by said controller contain a variable number of padding bits having a predetermined pattern.

A base station in a communication system in which a plurality of communication devices nominally transmit data at a variable rate and which nominally vary transmit power in response to said variable rate, said base station comprising:

• means for directing a first of said plurality of communication devices to continuously transmit RF energy at a full rate power level irrespective of said variable rate, whereby interference is reduced proximate said first communication device due to continuous transmission thereby;
• and
• means for receiving said RF energy continuously transmitted by said first communication device;
• means for determining whether one of said plurality of communication devices is continuously transmitting RF energy at a full rate power level irrespective of said variable rate;
• wherein said means for determining examines a first N bits of signaling traffic of a frame transmitted by said one of said plurality of communication devices to determine whether said one of said plurality of communication devices is continuously transmitting RF energy.
