Abstract: Scrambling code is initialized based on a parameter, n′RNTI, that changes from a given block of sub-frames to a subsequent block of sub-frames wherein the parameter is derived using one of the following formulas: n′RNTI=(nRNTI+SFN)mod 216 n′RNTI=(nRNTI+k)mod 216 where nRNTI is a temporary identifier associated with a mobile device connected to said cell and for which said scrambling code is applicable; and SFN is a system frame number associated with said at least one of said sequence of sub-frames; and k is a sub-frame counter.

Abstract: Scrambling code is initialized based on a parameter, n′RNTl, that changes from a given block of sub-frames to a subsequent block of sub-frames wherein the parameter is derived using one of the following formulas: n′RNTl=(nRNTI+SFN)mod 216 n′RNTl=(nRNTI+k)mod 216 where nRNTI is a temporary identifier associated with a mobile device connected to said cell and for which said scrambling code is applicable; and SFN is a system frame number associated with said at least one of said sequence of sub-frames; and k is a sub-frame counter.

Abstract: A communication system is disclosed in which a base station communicates with a reduced bandwidth machine-type-communication (MTC) device by dividing the base station's cell bandwidth into non-overlapping band portions, each band portion comprising a respective set of contiguous resource blocks that occupy a frequency bandwidth not exceeding the bandwidth of the MTC device, and each band portion having a respective index for identifying that band portion. The base station obtains: i) an index of a band portion for use by the MTC device; and ii) information for identifying an allocation of at least one resource block within that band portion. The base station generates and signals, to the MTC device, control data for uniquely identifying a position of the allocation of at least one resource block, within said cell bandwidth.

Abstract: A mobile communications system is proposed in which mobile communications devices are arranged to transmit signals to and to receive signals from a base station using one or a subset of available sub-bands, with the base station being configured to move the mobile communications devices between the sub-bands. An anchor sub-band is also provided on which idle mobile communications devices camp until they are moved to one or more other sub-bands in addition to or instead of the anchor sub-band.

Abstract: A communication system is disclosed, in which a mobile communication device communicates user data using a communication bearer provided via a first base station and a second base station of the communication system. The base stations are configured to determine a packet delay for communicating user data using said communication bearer based on the time when the first base station started PDCP processing for a data packet communicated using said communication bearer, and based on the time when the data packet was acknowledged by said mobile communication device to the second base station.

Abstract: A communications system is described that has a base station and a number of user devices, including legacy user devices and non-legacy user devices. The base station generates control data for transmission to the user devices, the control data including common control data for reception and decoding by a plurality of user devices and user specific control data for reception and decoding by a specific user device. The common control data is for reception and decoding by the non-legacy user devices and cannot be decoded by the legacy user devices. The common control data is repeated within multiple subframes for reception and decoding by non-legacy user devices. The non-legacy user devices are typically Machine Type Communications (MTC) user devices.
