Patent number: 9603029Abstract: A mobile communications network includes plural base stations in a network and configured to transmit to mobile communications devices a broadcast signal providing a sequence of data blocks in a sequence of transmission frames, each data block of the sequence being transmitted by each of the base stations contemporaneously for each of the sequence of transmission frames. One or more relay nodes are configured to receive the broadcast signal transmitted by one of the base stations and retransmit the broadcast signal, as the sequence of data blocks in the sequence of transmission frames on the same frequency as the broadcast signal transmitted by the base station, so that one or more of the mobile communications devices can receive the broadcast signal and recover the sequence of data blocks from one or both of the broadcast signal transmitted by the base station or the broadcast signal transmitted by the relay node.Type: GrantFiled: January 8, 2014Date of Patent: March 21, 2017Assignee: SCA IPLA HOLDINGS INC.Inventors: Stephen Barrett, Alan Jones

Patent number: 9585122Abstract: A method of communicating data between a base station and a plurality of terminal devices in a wireless telecommunications system. The method comprises transmitting data from the base station to the plurality of terminal devices in a multicast transmission and transmitting response signals from the terminal devices to the base station to indicate whether the respective terminal devices have successfully received the multicast transmission. The use of a multicast transmission provides an efficient mechanism for communicating the same data to a plurality of terminal device, for example as might be desired in a machine-type communication network.Type: GrantFiled: February 12, 2014Date of Patent: February 28, 2017Assignee: SCA IPLA HOLDINGS INCInventors: Yuichi Morioka, Stephen John Barrett, Phil Young, Martin Beale

Publication number: 20170055243Abstract: 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: November 3, 2016Publication date: February 23, 2017Applicant: SCA IPLA HOLDINGS INC.Inventor: Martin BEALE

Publication number: 20170055244Abstract: A wireless communications system includes a base station, a plurality of intermediate devices, and a terminal device. Downlink communications may be provided directly from the base station to the terminal device, including control signals which instruct the terminal device where to send uplink data. This enables the base station to directly control scheduling of uplink communications, and in particular to define an uplink route from the terminal device to the base station via one or more intermediate devices. Power is conserved at the terminal device on the uplink because a lower power transmission can be used which although insufficient to reach the base station can reach the intermediate device. The terminal device is not required to determine the uplink path itself and therefore does not require complex, expensive, and power consuming control logic.Type: ApplicationFiled: November 4, 2016Publication date: February 23, 2017Applicant: SCA IPLA HOLDINGS INCInventor: Yuichi MORIOKA
