A method for a user equipment sending an uplink resource scheduling request in a long term evolution mobile communication system and the user equipment thereof are provided. The present invention relates to a technique for the user equipment sending the uplink resource scheduling request in a long term evolution system, for reducing the user data transmission delay. The embodiments of the present invention set the minimum alternative option of the scheduling request transmission cycle configuration parameter as 2 ms or 1 ms, that is to say, add 2 ms or 1 ms, or 2 ms and 1 ms to the alternative option of the scheduling request transmission cycle configuration parameter, therefore, improving the flexibility of the whole system in the scheduling request transmission cycle configuration. When the data delay is required to be less, the user data transmission delay can be reduced, by using the 2 ms or 1 ms scheduling request transmission cycle configuration, to the delay requirement of 10 ms as close as possible.

A method and a device for transmitting downlink information in a multi-carrier aggregation system are provided. The Method includes: a base station side sends a downlink subframe to a terminal side, wherein, the physical downlink control channel (PDCCH) in the downlink subframe is used for bearing the downlink control indicating information and the carrier scheduling indicating information corresponding to each downlink control indicating information. It solves the problem that the terminal side can not clearly identify the downlink control information (DCI) of different carriers, which is caused by that the length of DCI may be same due to the difference of the bandwidths of carriers in the carrier aggregation system.

A method for channel content alternation notification and channel re-detecting is provided. The method is: a base station determines that the configured carried content of multimedia broadcast multicast service (MBMS) point to multipoint control channel (MCCH) is altered, and transmits the notification about alternation of the carried content of MCCH to a terminal through a physical downlink control channel (PDCCH); the terminal re-detects MCCH according to the notification after the terminal received the notification. A system and a device for channel re-detecting are provided. The terminal can recognize whether the carried content of MCCH is altered, and re-detect MCCH in case of altered without re-detecting MCCH periodically, therefore it is beneficial to save the resources of terminal.

The present invention provides two methods for configuring transmit power of sounding reference signal (SRS), a network device and a UE. One of the methods includes: with a network device, determining SRS transmit power parameters according to power level of signal previously sent from a UE received by each cell to be detected and/or information of cells to be detected by the UE, and sending the SRS transmit power parameters to the UE. The present invention can have an overall consideration on path losses of multiple cells to be detected when calculating the SRS transmit power. Therefore, the power of the cell having poor channel quality for receiving SRS can be guaranteed, in order to ensure the accuracy of channel estimation.
