摘要： A HSDPA type mobile communication system includes a base station and a mobile station. The base station sets the uplink control channel with the mobile station to transmit a pilot signal. The mobile station measures a reception quality of the pilot signal to transmit the quality information to the base station using the uplink quality control channel. The base station performs transmission control of data for the mobile station using the quality information. The mobile station is set to perform control of starting and stopping transmission of the quality information so that the quality information is transmitted only as required. Therefore, power consumption in the mobile station can be reduced, interference wave power in the uplink can be reduced, and capacity of the uplink can be increased.

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.
