Patent number: 11647510Abstract: 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: GrantFiled: May 3, 2021Date of Patent: May 9, 2023Assignee: SCA IPLA HOLDINGS INCInventor: Martin Beale

Patent number: 11399353Abstract: A telecommunications system communicating data to/from one or more terminals, including one or more transmitters to transmit first and second carriers over respective first and second frequency bandwidths. During a first time period the transmitters can transmit data receivable by first and second classes of terminal on the first and second carriers. During a second different time period, the transmitters can transmit data to the second class of terminal on the first and second carriers in combination. A data transmission format on the first carrier in the first time period is incompatible with a user data transmission format on the second carrier during the first time period. The transmitters can transmit control data on the first carrier in the first time period which is receivable by the second class of terminal to enable the second class of terminal to maintain synchronisation with the first carrier during the first time period.Type: GrantFiled: August 8, 2019Date of Patent: July 26, 2022Assignee: SCA IPLA HOLDINGS INC.Inventors: Peter Darwood, Martin Beale
