    摘要： A communications node operable to communicate with another communications node over a communications channel having a plurality of frequency resources, the communications node includes data defining a division of the communications channel into a plurality of contiguous sub-bands each having N frequency resources, wherein each frequency resource in a sub-band has a corresponding frequency resource in each of the other sub-bands, data defining an initial allocation of the frequency resources, a resource determination module operable to apply a frequency shift to the initially allocated frequency resources in accordance with a frequency hopping sequence to determine frequency resources to use for communicating information with the other communications node, wherein the frequency shift applied moves the initially allocated frequency resources to corresponding frequency resources in another sub-band, a transceiver for communicating information with the other communications node using the determined frequency resource.

    摘要： 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.

    摘要： 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.

    摘要： A communication system is disclosed in which a communication device communicates with communication apparatus that operates a cell within which the communication device is located. The cell is operated as a licensed assisted access (LAA) cell and has an associated physical uplink control channel (PUCCH). The communication device has a controller that is adapted to: generate a control signal for transmitting to said communication apparatus; perform a clear channel assessment (CCA) on said PUCCH before the control signal is transmitted; and block transmission of the control signal on said PUCCH when said CCA indicates that said channel is not clear. The communication device is further adapted, when said controller has not blocked said transmission of the control signal, to transmit the control signal to said communication apparatus in said PUCCH.

    摘要： A method of signaling resource allocation data in a communication system which uses a plurality of sub-carriers arranged in a sequence of chunks. An allocation of the sub-carriers for each of a plurality of user devices is received. The received allocations are processed to determine, for each user device, data identifying a start chunk and an end chunk within the sequence of chunks, which depend upon the sub-carriers allocated to the user device. Different resource allocation data is generated for each of the user devices using a predetermined mapping which relates the data identifying the corresponding start chunk and end chunk determined by the processing step to resource allocation data comprising a unique value. The respective resource allocation data is signaled to each of the plurality of user devices.
