Изобретение относится к системам радиосвязи, в частности к системам передвижной сотовой радиосвязи, и может быть использовано с устройствами, расположенными на подвижном автотранспорте или, например передвигающимся пешеходом. Система радиосвязи включает в себя базовую станцию, которая связана с рядом подвижных станций посредством первого набора каналов для передачи звука и второго набора каналов для передачи данных причем первый набор каналов выполнен в виде ряда групп каналов, имеющих одинаковую полосу частот с возможностью работы каждой группы на отдельной частоте в режиме множественного доступа с частотным разделением, а все каналы одной группы выполнены с возможностью работы на одной несущей частоте с использованием множественного доступа с кодовым разделением (МДКР). Каждый канал второго набора выполнен с возможностью работы на несущих частотах каналов первого набора с использованием МДКР, а полоса частот каналов второго набора соответствует полосе частот, занятой по крайней мере несколькими группами каналов первого набора.The invention relates to radio communication systems, in particular to mobile cellular radio communication systems, and can be used with devices located on a mobile vehicle or, for example, a walking pedestrian. The radio communication system includes a base station that is connected to a number of mobile stations through a first set of channels for transmitting sound and a second set of channels for transmitting data, the first set of channels being made as a series of groups of channels having the same frequency band with each group working on a separate frequency in the multiple access mode with frequency division, and all the channels of one group are configured to operate on a single carrier frequency using code-division multiple access business unit (mdcr). Each channel of the second set is designed to operate on the carrier frequencies of the channels of the first set using CDMA, and the frequency band of the channels of the second set corresponds to the frequency band occupied by at least several groups of channels of the first set.
