    摘要: A communication system is presented in which a base station is provided for communicating with a plurality of mobile communication devices in a cellular communication system. The base station operates one of more communication cells and communicates subframes, with each of the plurality of communication devices within the cell(s), each comprising the communication resources of a control region for communicating a control channel and the communication resources of a data region for communicating a respective data channel. The base station communicates a control channel having a first DMRS sequence in a control region of some subframes and a control channel having a second DMRS sequence in a control region of other subframes. The second control channel may be transmitted in a radio beam focussed spatially in a direction of a communication device. The first control channel may be transmitted omnidirectionally throughout the cell(s).

    摘要: A method of allocating resources in a communication system which uses a plurality of sub-carriers arranged in a sequence of physical resource blocks wherein adjacent blocks of the sequence are arranged in groups. The method includes, in a base station, determining at least one virtual resource block for allocation to a mobile communications device, signalling data identifying each virtual resource block to the mobile communications device, and mapping each allocated virtual resource block, using predetermined mapping data, onto a plurality of spaced physical resource blocks to determine the physical resource blocks to be used for communications with the mobile communications device. At least part of the predetermined mapping data defines an equation for the location of a further physical resource block, relative to a first physical resource block.

    摘要: A cellular communications system includes a plurality of base stations and a plurality of user devices. In use, each user device is associated with a base station and is operable to communicate with the associated base station over a communication channel having a plurality of frequency resources. Each user device has a respective initial allocation of said frequency resources. Each user device is operable to apply a frequency shift to its initially allocated frequency resource in accordance with a frequency hopping sequence. The user devices that are associated with the same base station are operable, in use, to use the same frequency hopping sequence and are synchronized with each other so that, at any point in time, a common frequency shift is applied by the user devices associated with the same base station. User devices associated, in use, with different base stations use different frequency hopping sequences.
