Radio System Configuration

摘要

A method, in which a bandwidth of a carrier frequency is allocated to subbands and one or more of the subbands is assigned to a radio network element to be used in radio communication between the radio network element and user equipment having a radio connection with the radio network element.

1. An apparatus, comprising:
a transceiver for providing a radio cell for radio communication with user equipment, wherein the radio cell communicates with the user equipment in a coverage area that is overlapped by a macro coverage area of an existing macro network, one or more processors; and one or more memories including computer program code, the one or more memories and the computer program code configured, with the one or more processors, to cause the apparatus to perform at least the following: configure the transceiver to use a plurality of frequency subbands of a bandwidth of a carrier frequency allocated for use by the radio cell for radio communication with the user equipment in the macro coverage area, wherein at least one of the subbands of the plurality of frequency subbands allocated for use by the radio cell is a primary subband used for transmission of control channel information and at least one other subbands of said plurality of frequency subbands are secondary subbands allocated for use by the radio cell for transmission of user data, and wherein the primary and secondary subbands are allocated to avoid interference with other devices communicating in the macro coverage area on the carrier frequency allocated for use for radio communication with the user equipment, and wherein the primary subband and the secondary subbands are different than frequency subbands in use by the existing macro network; wherein the transceiver is configured to transmit a primary broadcast channel in a single frequency network mode with a primary broadcast channel of the overlay radio network; wherein the radio cell of the radio network is configured to transmit on a broadcast channel information on the subband allocation to radio network elements of the another radio network; and wherein the radio cell of the radio network is configured to transmit as information on sub band allocation a mapping of cell identities and subbands.
