    摘要: The present invention relates to an uplink power control method and user equipment, which involve determining a power correction factor by considering the number of antenna ports. According to the present invention, even when a base station transmits the same power control information to the user equipment, the user equipment maps the power control information to another power correction factor and determines an uplink transmission power depending on an uplink transmission condition. Thus, uplink power control can be performed in a more efficient manner.

    摘要: A user equipment (UE) transmits uplink control information (UCI) of 3 bits or more to a base station (BS) after modulating the UCI into 1-bit or 2-bit sub-UCI units. Here, the UE maps each 1-bit or 2-bit sub-UCI unit to one of a plurality of corner constellation points regardless of modulation order of data which is multiplexed with the UCI. The corner constellation points are points having a maximum Euclidean distance from among a plurality of constellation points corresponding to the modulation order.

    摘要: A method for transmitting, at a user equipment having N (N being an integer greater than 1) transmission antennas, an uplink signal to a base station and a method for receiving, at the base station, an uplink signal from the user equipment are disclosed. The base station transmits reception capability information of the base station to the user equipment. Reception capability information includes information indicating that the base station may receive a signal transmitted through a maximum of M (M being an integer greater than 1) transmission antennas. The user equipment transmits the uplink signal using N transmission antennas if N is not greater than M and transmits the uplink signal using M transmission antennas if N is greater than M.

    摘要: A method for transmitting channel status information (CSI) of downlink multi-carrier transmission includes generating the CSI including at least one of a rank indicator (RI), a first precoding matrix index (PMI), a second PMI and a channel quality indicator (CQI) for one or more downlink carriers, the CQI being calculated based on precoding information determined by a combination of the first and second PMIs, determining, when two or more CSIs collide with one another in one uplink subframe of one uplink carrier, a CSI to be transmitted on the basis of priority, and transmitting the determined CSI over a uplink channel. If a CSI including an RI or a wideband first PMI collides with a CSI including a wideband CQI or a subband CQI, the CSI including a wideband CQI or a subband CQI has low priority and is dropped.
