    摘要: Provided are a wireless communication terminal device and a power allocation method, wherein transmission channel quality information, regarding a Pcell having a high probability that UCI is multiplied therein, can be accurately estimated by an SRS having high priority in power allocation, and an eNB can instruct appropriate transmission power to an UL channel which transmits the subsequent UCI. A power scaling detection unit (108) detects whether or not a total transmission power value of the UL channels transmitted by the plurality of CC exceeds the maximum transmission power specific to the UE. When a plurality of SRS are simultaneously transmitted using a Pcell and a Scell, and power scaling occurs, a power scaling control unit (109) performs power allocation so that transmission power of the SRS of the Pcell has the higher priority than that of the SRS of the Scell.

    摘要: Provided is a radio communication base station device which can prevent lowering of use efficiency of a channel communication resource for performing a frequency diversity transmission when simultaneously performing a frequency scheduling transmission and the frequency diversity transmission in a multicarrier communication. In the device, a modulation unit (12) executes a modulation process on Dch data after encoded so as to generate a Dch data symbol. A modulation unit (22) executes a modulation process on the encoded Lch data so as to generate an Lch data symbol. An allocation unit (103) allocates the Dch data symbol and the Lch data symbol to respective subcarriers constituting an OFDM symbol and outputs them to a multiplexing unit (104). Here, when a plurality of Dch are used for a Dch data symbol of one mobile station, the allocation unit (103) uses Dch of continuous channel numbers.

    摘要: Provided is a base station capable of searching cells of different frequencies without losing a opportunity of data communication by effectively performing SCH data transmission. The base station (100) includes: an encoding unit (101) for encoding SCH data; a modulation unit (102) for modulating the encoded SCH data; a transmission timing setting unit (103) for setting the transmission timing of the SCH data; encoding units (104-1 to 104-N) for encoding user data (#1 to #N), modulation units (105-1 to 105-N) for modulating the encoded user data (#1 to #N); and an IFFT unit (106) for mapping the SCH data and the user data (#1 to #N) to sub carriers (#1 to #K) and performing IFFT to generate an OFDM symbol. The transmission timing setting unit (103) sets the transmission timing of the SCH data so that, for example, the SCH data transmission cycle and the frame cycle are relatively prime, i.e., the maximum common multiple of them is 1.

    摘要: This invention relates to signaling of resource assignments in cross-carrier scheduling scenarios. In order to enable cross-carrier scheduling in a mobile communication system using carrier aggregation while avoiding erroneous detection of assigned physical resources that could lead to HARQ soft buffer corruption/degradation of the system throughput, the invention suggests a scheme for explicitly indicating within downlink control information (DCI) including a resource assignment for the downlink (or uplink) the number of OFDM symbol(s) used for control signaling within a sub-frame on a component carrier on which resources are assigned by the DCI. In one exemplary implementation the number of OFDM symbol(s) used for control signaling is the PCFICH values signaled in a 3GPP LTE-A network. The indication of the OFDM symbol(s) within the sub-frame on the assigned component carrier may for example be jointly encoded with other control signaling information, e.g. with the carrier cation of the carrier indicator field.
