FIELD: communications engineering; common-user channel message transfer in code-division multiple access system.
SUBSTANCE: control message generator of base station produces message incorporating information about extension code for extending generator common-user backward channel message, and common-user forward channel transmitter transfers control message over common-user forward channel to mobile station. Control station analyzer of mobile station analyses information presenting assigned extension code included in control message received over common-user forward channel; extension code generator shapes extension code basing on extension code information, and channel transmitter extends common-user backward channel message by means of extension code and transmits extended message of common-user backward channel.
EFFECT: facilitated procedure; improved design of device.
