摘要： A plurality of cells comprise a primary cell with no configured scheduling request (SR) resources and a secondary cell with configured SR resources. A wireless device receives an activation command indicating activation of the secondary cell. The wireless device initiates a random access procedure when in a subframe: an SR process is pending; no uplink data channel resources are available for transmission; and a time alignment timer of an sTAG comprising the secondary cell is not running.

摘要： A method for supporting a device to device (D2D) communication in a base station of a mobile communication system according to one embodiment of the present specification comprises the steps of: determining one or more device groups including one or more devices among a plurality of devices; determining radio resources for measuring channels for the determined device groups; and transmitting, to the devices included in the respective groups, information on the radio resources for measuring the channels corresponding to the groups. According to the embodiment of the present specification, complexity of measuring a channel state in the D2D communication is reduced, and many more devices can measure the channel state using limited radio resources and can transmit and receive data. The present disclosure relates to re-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE).

摘要： A dual band spectrum allocation system and method for wireless data communications uses discrete bands for upstream and downstream data communications. A preferred embodiment uses unlicensed UNII bands for license-free data transmissions from a subscriber to a hub, and uses relatively interference free licensed bands for data transmissions from a hub to subscribers, thereby allowing use of greater bandwidth, simplifying system licensing and reducing filtering requirements for subscribers.

摘要： The present invention relates to transmission and reception of downlink control information in a communication system. In particular, a serving base station transmits to a terminal a downlink control information which includes a first field with a scheduling information and a second field with interference parameters (interference information). The receiver employs the interference parameters for interference estimation used in interference cancellation or suppression.

摘要： A communication method and an apparatus for transferring interference-related control information in order to enhance reception performance of a user terminal that receives downlink signals in a cellular mobile communication system based on a long term evolution-advanced (LTE-A) system are provided. The method includes receiving transmission parameters of interference, which include information on a resource by which interference data is not transmitted, performing blind detection using the information on a resource by which interference data is not transmitted, performing error correction encoding using the transmission parameters of the interference and the blind detection result, and decoding the received data.
