Abstract: Provided are a resource scheduling method, a resource determining method, an eNB, and a user equipment. The resource scheduling method for wireless communication is performed by the eNB. The wireless communication involves at least a first carrier and a second carrier. The resource scheduling method includes: transmitting a DCI in the first carrier to a UE to schedule downlink resources for a PDSCH of the second carrier, wherein the eNB is able to start transmitting a burst in the second carrier at a flexible time independent of the subframe boundaries of the second carrier after the second carrier is occupied by the eNB, and the DCI for a flexible PDSCH of the burst different from the normal PDSCH of the second carrier contains information on the time period scheduled for the flexible PDSCH. The flexible PDSCH and its corresponding RS can reuse the DwPTS subframe structure for minimal specification impact.

Abstract: In a case where a second reference signal for a second communication system is transmitted in addition to a first reference signal for a first communication system, resources that affect a reception apparatus compatible only with the first communication system can be minimized, and the throughput can be prevented from being deteriorated. As resources for a reference signal CSI-RS for LTE-A, last half symbols in a time direction of a resource unit RB/Sub-frame defined in a frequency-time domain are used, and the CSI-RS is allocated in a position up to the last two symbols or in the last symbol, or the like, of a particular RB/Sub-frame and transmitted when a reference signal 4RS for LTE is transmitted to a reception apparatus in addition to transmitting CSI-RS for LTE-A. The reception apparatus receives CSI-RS allocated in the last half symbol of RB/Sub-frame on the basis of CSI-RS allocation information, measures channel quality such as CQI, PMI or RI by using this CSI-RS, and transmits and reports feedback information containing channel quality information to a transmission apparatus.

Abstract: The purpose of the present invention is to be able to simultaneously generate three or more sets of CSI within a predetermined time interval, without degrading the accuracy of the CSI, to achieve CoMP control for flexible switching of base stations. At predetermined intervals or at timing coincident with reception of trigger information, a generation unit (230) uses a CSI-RS resource to measure a desired signal component and interference component, and generate CSI. A transmission unit (240) transmits control information including the CSI. During a given interval (for example, during four sub-frames) following reception of trigger information, the generation unit (230) does not measure the interference component, instead using the most recent previously measured interference component, to measure the channel quality.

Abstract: The present disclosure provides an orthogonal codes based code division multiplexing method of performing the code division multiplexing of demodulation reference signals in multiple layers of resource blocks by using orthogonal matrices, the method comprising: changing the order of chips in particular rows of a first orthogonal matrix to obtain a second orthogonal matrix with the changed order of chips; and multiplying the chips in respective rows of the second orthogonal matrix by the demodulation reference signals in corresponding layers of resource blocks correspondingly in the time direction to obtain code division multiplexing signals. The technical scheme of the present disclosure can improve the power jitter situation of downlink signals on the time, thereby the usage efficiency of the power amplifier at the base station side can be improved.
