20120243440 | METHOD FOR FEEDING BACK CHANNEL STATE INFORMATION AND DETERMINING COORDINATED MULTI-POINT MODE AND DEVICE - A method for feeding back channel state information and determining a coordinated multi-point mode and a device are disclosed. The method for feeding back channel state information includes: obtaining multiple pieces of channel state information of multiple cells in a coordinated multi-point mode; and selecting the preset quantity of pieces of irrelevant channel state information from the multiple pieces of channel state information, and feeding back the selected channel state information to a corresponding network side device. | 09-27-2012 |
20120314613 | METHOD FOR REPORTING AND OBTAINING CHANNEL STATE INFORMATION, ENODEB, AND USER EQUIPMENT - A method for reporting and obtaining channel state information, an eNodeB, and a user equipment are disclosed. The method for reporting channel state information includes: determining a reported content in channel state information (CSI) of downlink component carriers according to priorities of contents-in-CSI, where the CSI of the downlink component carriers includes the reported content and a content that is not to be reported; and reporting the reported content to an eNodeB on a physical uplink control channel (PUCCH). By determining a reported content in CSI according to a priority, the shortage of a CSI reporting resource may be relieved. | 12-13-2012 |

20140023028 | POWER CONTROL METHOD, USER EQUIPMENT, AND BASE STATION - Embodiments of the present invention disclose a power control method, a user equipment, and a base station. The method according to an embodiment of the present invention includes the following: a user equipment UE receives a transmitter power control TPC command sent by a base station, where the TPC command is used to indicate a power adjustment value of one carrier; and if the UE does not send a physical uplink control channel PUCCH in a previous uplink subframe of a current uplink subframe of the one carrier, performing, by the UE, according to a PUCCH transmit power used when the UE sends a latest PUCCH from among multiple carriers and the power adjustment value, TPC accumulation to obtain an updated PUCCH transmit power of the one carrier, where the multiple carriers include the one carrier. | 01-23-2014 |
20140050169 | METHOD FOR ACTIVATING OR DEACTIVATING EXTENDED CARRIER, AND BASE STATION - A method for activating or deactivating an extended carrier and a base station are disclosed, and relate to the field of radio communications. The method includes: configuring an extended carrier of an independent carrier for a user equipment, where the extended carrier includes at least one of an adjacent extended carrier of the independent carrier and a non-adjacent extended carrier of the independent carrier; and activating or deactivating the extended carrier by using a bit in an original MAC CE and/or an extended MAC CE and corresponding to an index of the extended carrier. The base station includes a configuring module and an activating or deactivating module. | 02-20-2014 |
20140314014 | UPLINK TRANSMISSION POWER CONTROL METHOD AND USER EQUIPMENT - An uplink transmission power control method and a user equipment are provided, where the method includes: determining, by a UE, whether uplink channels are simultaneously transmitted over adjacent subframes between multiple carriers; where the adjacent subframes between the multiple carriers are partially overlapped; and timing advance values of the multiple carriers are different; and if uplink channels are simultaneously transmitted over adjacent subframes between multiple carriers, processing, by the user equipment, an uplink channel transmitted over the last symbol on a partially overlapped subframe of another carrier except a carrier having the greatest timing advance value, so that total transmission power of the uplink channels is lower than the maximum transmission power or an interference level of the user equipment. | 10-23-2014 |
20150163750 | METHOD AND APPARATUS FOR CONTROLLING UPLINK POWER OF USER EQUIPMENT IN CARRIER AGGREGATION SCENARIO - The present invention provides a method and an apparatus for controlling uplink power of a user equipment, where the method includes: separately acquiring first maximum transmit power of the user equipment corresponding to a first subframe and second maximum transmit power of the user equipment corresponding to a second subframe; and when the first maximum transmit power and the second maximum transmit power are different, using a minimum value of the first maximum transmit power and the second maximum transmit power as first configured maximum transmit power, and performing power control over transmit power of multiple carriers in an overlap region according to the first configured maximum transmit power, so that total transmit power of the multiple carriers in the overlap region after the power control is lower than or equal to the minimum value of the first maximum transmit power and the second maximum transmit power. | 06-11-2015 |
20150180631 | Method and Apparatus for Transmitting Reference Signal in Device-to-Device (D2D) Communication - A method and an apparatus for transmitting information in device-to-device (D2D) communication are provided, where the method includes determining, by a first user equipment, in a communication resource for D2D communication, a target resource used to bear a reference signal (RS), where the target resource is according to characteristic information used in selecting the target resource, and the characteristic information used in selecting the target resource includes at least one of the following two items: characteristic information used to uniquely identify the first user equipment, and characteristic information used to uniquely identify a second user equipment that performs D2D communication with the first user equipment; and transmitting, by the first user equipment, the RS to the second user equipment using the target resource. | 06-25-2015 |
