摘要： 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.

摘要： Disclosed are a method for determining and indicating a transmission resource, and a terminal and a base station. The method comprises: a base station and a UE agreeing that at least one subframe of a set number of wireless frames is used as a reference subframe, and considering that all REs in the reference subframe which are probably occupied by a ZP/NZP CSI-RS are REs unable to be used for EPDCCH transmission; and the base station sending to a UE configuration information about REs in other subframes which are occupied by the ZP/NZP CSI-RS in the reference subframe, so that the UE can determine REs in other subframes, which are probably occupied by the ZP/NZP CSI-RS but are in fact not occupied by the ZP/NZP CSI-RS as REs used for the EPDCCH transmission, thereby increasing the number of REs used for EPDCCH transmission, and reducing the system overheads.

摘要： The present disclosure provides a power control method and a power control apparatus for uplink channels. The power control method includes steps of: determining, by a UE, target transmission powers for the uplink channels in each carrier group, the UE being configured with at least two carrier groups, UCI in each carrier group being fed back via PUCCH(s) and/or PUSCH(s) on at least one uplink carrier corresponding to the carrier group; determining, by the UE, whether or not a sum of the target transmission powers for the simultaneous transmission uplink channels exceeds an allowable maximum transmission power of the UE; and in the case that the sum of the target transmission powers for the simultaneous transmission uplink channels exceeds the allowable maximum transmission power of the UE, reducing, by the UE, powers for the PUCCH(s) and/or PUSCH(s) carrying the UCI of different carrier groups among the simultaneous transmission uplink channels at least in accordance with priorities of types of the UCI, so that a sum of the transmission powers for all the uplink channels in a current uplink subframe does not exceed the allowable maximum transmission power of the UE. According to the present disclosure, it is able to perform uplink power control in the case that the UE supports the independent UCI feedback for different carrier groups.

The method in an embodiment of the present application comprises: a terminal receives data over a first carrier and a second carrier, the data over the first carrier being scheduled by a first base station and the data over the second carrier being scheduled by a second base station; the terminal generates first uplink control information for the first carrier, and/or the terminal generates second uplink control information for the second carrier; the terminal transmits the generated uplink control information over one uplink carrier according to a TA value and a reference carrier, the uplink control information comprising at least one of the first uplink control information and the second uplink control information. Therefore, the terminal can simply transmit over one uplink carrier the uplink control information corresponding to the downlink carriers scheduled by different base stations scheduling data for the terminal.
