Publication number: 20180152929Abstract: A method communicating data between a base station and a terminal device in a wireless telecommunications system, for example an LTE-based system. The wireless communication system uses plural frequency sub-carriers spanning a system frequency band. Physical-layer control information for the terminal device is transmitted from the base station using sub-carriers selected from across the system frequency band, for example to provide frequency diversity. However, higher-layer data for the terminal device is transmitted using only sub-carriers selected from within a restricted frequency band which is smaller than and within the system frequency band. The terminal device is aware of the restricted frequency band, and as such need only buffer and process data within this restricted frequency band during periods where higher-layer data is being transmitted. The terminal device buffers and processes the full system frequency band during periods when physical-layer control information is being transmitted.Type: ApplicationFiled: January 24, 2018Publication date: May 31, 2018Applicant: SCA IPLA HOLDINGS INCInventor: Martin BEALE
