    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 silent chain is provided with strength and elongation of respective link rows made uniform, elongation of every link made equal regardless of elastic and/or plastic deformation, and inexpensive production cost. The silent chain includes a first link row, a second link row, a connection pin and a pin stopper. Each of the first and second link rows consists of a guide plate and the same number of link plates whose shapes and sizes are the same. The first and second link rows are staggered in the longitudinal direction of the chain, and connected in alternating, interleaved relationship by connection pins. The guide plates and the link plates of the first and second link row are relatively rotatable to the connection pins. The first and second link rows are alternately arranged in mirror image symmetry.
