BASE STATION, TERMINAL, BAND ALLOCATION METHOD AND DOWNLINK DATA COMMUNICATION METHOD Russian patent published in 2014 - IPC H04W8/22 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to communication engineering and can be used in wireless communication systems. A first system co-exists with a second system in which a plurality of unit bands can be allocated to a single transmission. In a base station (200), an OFDM signal generation unit (225) maps primary synchronisation channel (P-SCH), secondary synchronisation channel (S-SCH), primary broadcast channel (P-BCH) and dynamic broadcast channel (D-BCH), which can be decoded by both an LTE terminal and an LTE+ terminal, to some of a plurality of unit bands available to the station itself. The OFDM signal generation unit (225) also maps D-BCH+, which can be decoded only by an LTE+ terminal, to all unit bands to produce a multiplexed transmission signal. When the terminal which has transmitted terminal capability information is an LTE+ terminal, a control unit (265) transmits a band movement indication which indicates changes in the reception band of that terminal.

EFFECT: high efficiency of using resources.
