Abstract:
1. A base station of a radio access network comprising: transceiver circuitry configured to communicate a frame of information over a radio interface with one or more first radio terminals configured in accordance with a first radio access technology system that permits radio terminal communications over a first channel bandwidth and with one or more second radio terminals configured in accordance with a second radio access technology system that permits radio terminal communications over a second channel bandwidth; and a frame handler configured to process data to be transmitted to the first and second radio terminals into a frame with multiple symbol time periods using a frame format that is compatible with both the first radio access technology system and the second radio access technology system so that both the first and second radio terminals may receive and extract data from the frame intended for each of those radio terminals, wherein the frame format includes a first data allocation having an amount up to a maximum bandwidth equal to the first channel bandwidth for transmission to one of the first radio terminals during a symbol time period and a second data allocation having an amount up to a maximum bandwidth equal to the second channel bandwidth for transmission to one of the second radio terminals during the same symbol time period, and wherein the second channel bandwidth is grater than the first channel bandwidth and spans across at least one first channel bandwidth.
