    摘要: It is possible to prevent lowering of a throughput of a radio communication system even when propagation path environments of an uplink line and downlink line are asymmetric. A maximum proper value calculation unit (115) calculates a maximum proper value from a channel matrix. A maximum proper value comparison unit (116) compares the maximum proper value with a maximum proper value of the downlink line reported separately from a base station. According to the comparison result obtained by the maximum proper value comparison unit (116), a proper mode initiative instruction unit (117) decides to pass the proper mode initiative to a communication partner or to the local device. When the initiative is to be passed to the local device, this fact is reported to a proper bam correction unit (118). When the proper beam correction unit (118) gets the proper mode initiative, the proper beam correction unit (118) corrects the correlation matrix by using the proper values of both of the downlink line and the uplink line and instructs a directivity forming unit (103) to form a proper beam according to the correlation matrix after the correction.

    摘要: A wireless relay station apparatus for enabling a mobile station and a base station to reliably receive network coding data and to provide sufficient reception performance is provided. (1) A repeater divides data X received from a mobile station into important data and non-important data and divides data Y received from eNB into important data and non-important data. Next, (2) the repeater places the data so that important data Sx for the mobile station and important data Sy for the eNB do not overlap, XORs (exclusive ORs) them, and generates network coding data X (X) Y. (3) The repeater applies downlink propagation inverse characteristic H1−1 to important data portion Px (X) Sy for the mobile station and on the other hand, applies uplink propagation inverse characteristic H0−1 to important data portion Sx (X) Py for the eNB in the network coding data X (X) Y for transmission.

    摘要: It is possible to provide a radio communication terminal device, a radio communication base station device, and a CQI feedback method which can improve the CQI reproducibility while reducing the feedback overhead. A terminal channel judgment unit judges whether a local terminal is a TU terminal or a LOS terminal. A feedback CQI decision unit selects a Best-M report if the local terminal is the TU terminal, and selects a DCT report if the local terminal is the LOS terminal. The feedback CQI decision unit feeds back the CQI by using the selected report method.

    摘要: When power scaling is applied to multi-user MIMO, a reduction in transmission rate is suppressed and transmission efficiency is improved. When signals are transmitted through spatial multiplexing from a wireless base station 11 to a plurality of pieces of user equipment 12 and 13, notification of a transmission parameter (MCS) of the distant user equipment (UE-B) 13 is provided as control information to the adjacent user equipment (UE-A) 12. The user equipment 12 calculates, based on the received control information, a reception quality (CQI) after cancellation of a signal serving as an interference signal and destined for the other user equipment 13, and feeds back the calculated result to the wireless base station 11. Based on this feedback, the wireless base station 11 sets a transmission parameter (MCS) of each piece of the user equipment 12 and 13 using the CQI after the cancellation, and transmits signals intended for respective users through spatial multiplexing after performing power distribution between the users by power scaling.

    摘要: A base station transmits downlink signals to mobile terminals of users A to C with respective transmission power corresponding to downlink quality. A downlink quality estimating section (106) uses the transmission power from a transmission power control section to compare transmission power between the users, and estimates that a terminal with low transmission power has high downlink quality. The priorities are determined so that the priority is increased as the transmission power is lower. Thus determined priority information is output to a scheduling section (107). The scheduling section (107) performs scheduling based on the priority information. The section (107) assigns DSCH to terminals in ascending order of transmission power. User A is first assigned DSCH, user B is second assigned DSCH, and user C is third assigned DSCH. It is thus possible to perform scheduling and MCS selection of DSCH with the need of information from a terminal eliminated.
