1. A method comprising:
storing, in a terminal device of a cellular communication system, definitions for a first radio frame configuration defining a frame structure of a radio frame comprising at least one sub-frame dedicated only for downlink transmission [ , wherein the terminal device stores definitions for a plurality of different radio frame configurations each defining at least one flexible special sub-frame, wherein at least two of the plurality of different radio frame configurations have different sub-frame lengths] ;
storing, in the terminal device, definitions for a second radio frame configuration defining a frame structure of a radio frame comprising [ the ] at least one flexible special sub-frame configurable as either a [ flexible special ] downlink sub-frame or as an [ a flexible special ] uplink sub-frame, wherein the flexible [ special ] downlink sub-frame and the flexible [ special ] uplink sub-frame both comprise an uplink part and a downlink part, and wherein both the uplink part and the downlink part carry at least one of control information and a reference signal [ , wherein the definitions for the plurality of different radio frame configurations comprise the definitions for the first radio frame configuration and the definitions for the second radio frame configurations] ;
receiving, from a network element of a [ the ] cellular communication system, a radio signal carrying an information element indicating a radio frame configuration applied in a cell of the cellular communication system; and
selecting, on the basis of the received information element, a radio frame configuration amongst [ among ] a set of radio frame configurations comprising at least the first radio frame configuration and the second radio frame configuration and using the selected [ radio ] frame configuration in communication with the network element in the cell [ ,
wherein, among the at least two of the plurality of different radio frame configurations having different sub-frame lengths, either:
a radio frame configuration having a greater sub-frame length has a smaller sub-carrier spacing in sub-frames than another one of the at least two of the plurality of different radio frame configurations, or
a radio frame configuration having a smaller sub-frame length has a larger sub-carrier spacing in sub-frames than another one of the at least two of the plurality of different radio frame configurations] .
