摘要： A communication system is presented in which a base station operates a first cell using a first component carrier and a second cell using a second component carrier. A control channel and reference signals of a first type are provided using the first component carrier. The control channel and the reference signals of the first type are not provided, and reference signals of a second type are provided, using the second component carrier. The base station determines from results of measurements performed on reference signals of the second type whether or not the mobile communication device is within an area covered by said second cell and, if it is, transmits cell configuration information to the mobile communication device.

摘要： A communications system is provided in which persistently allocated resources used by a node to communicate data with another node of the communications system can be reallocated or new dynamic resources can be allocated to allow the node to communicate using both the persistently allocated resources and the dynamically allocated resources. The system does this without changing the structure of a control channel used to communicate resource allocations.

摘要： Communication apparatus is disclosed which is suitable for communicating with a mobile communication device in a communication system which uses a plurality of radio frames wherein each radio frame is subdivided in the time domain into a plurality of subframes, each subframe is subdivided in the time domain into a plurality of slots, and each slot is subdivided in the time domain into a plurality of symbols. The communication apparatus operates a communication cell, generates discovery signals, for use in a cell search procedure, each discovery signal comprising a pair of synchronisation signals and a further signal, and transmits each synchronisation signal and the further signal in a respective symbol of a radio frame. The symbol in which the further signal is transmitted separated, in the time domain, by no more than half a radio frame from at least one of said pair of synchronisation signals.

摘要： The application relates to HeNB GW and its role in handover procedures. Due to the increasing geographic density of small cells, the signalling load to the CN will increase. The application proposes to terminate mobility related signalling for the purposes of in the HeNB GW (14) as opposed to the MME (12) as is conventionally the case, thereby avoiding additional signalling with the core network. However, when the HeNB GW terminates the signalling, the security context is not updated between the MMM and the HeNB GW. In order to mitigate the security risk that this might cause, a number of handovers or 'hops' can beneficially be defined, e.g. by the operator, during which handover signalling will terminate in the small cell gateway. Once this predefined number of 'hops' has been reached, the next HeNB GW routes handover signalling via the core network for the next handover in order to ensure that the security context is updated.
摘要翻译：该申请涉及HeNB GW及其在移交程序中的作用。由于小型电池的地理密度不断增加，对CN的信号负载将会增加。为了避免与核心网络的附加信令，应用提出在HeNB GW（14）中为了与MME（12）不同的目的而终止与移动性有关的信令。然而，当HeNB GW终止信令时，MMM和HeNB GW之间的安全上下文不被更新。为了减轻这可能导致的安全风险，可以有益地定义多个切换或“跳”，例如。由运营商在此期间切换信令将终止于小小区网关中。一旦达到了预定数量的“跳”，下一个HeNB GW将通过核心网路由切换信令进行下一个切换，以确保更新安全上下文。
