20150117390 | PILOT SIGNAL TRANSMISSION METHOD AND RADIO COMMUNICATION APPARATUS - In a radio communication system, transmission of CAZAC sequences as the pilot signal sequences by using code division multiplexing as at least one of user multiplexing schemes, is done by dividing a system band as a frequency band usable in the system into frequency blocks B1 and B2 having bandwidths W1 and W2, generating the pilot signals of the frequency blocks B1 and B2 with a single carrier, using the pilot signal sequences having sequence lengths L1 and L2 corresponding to frequency blocks B1 and B2 respectively; and, transmitting the generated pilot signals as the pilot signals corresponding individual users, with multicarriers using an arbitrary number of frequency blocks among the plural frequency blocks | 2015-04-30 |
20150117391 | EQUALIZING METHOD IN A RECEIVER NODE OF A WIRELESS COMMUNICATION SYSTEM - The present invention relates to an equalizing method in a receiver node of a cellular wireless communication system, the method comprising: receiving at least one radio signal comprising a plurality of resource elements; obtaining interference information associated with the plurality of resource elements; extracting resource elements from the plurality of resource elements carrying data into a first set based on the interference information; dividing the resource elements in the first set into one or more sub-sets each comprising T number of resource elements; filtering the resource elements in said one or more sub-sets by applying a balanced whitening and energy focusing filter W so as to obtain filtered resource elements y; and equalizing the filtered resource elements y.

20150117392 | Method and Arrangement in a Wireless Communication System - The invention relates to methods and arrangements in a transmitting node for enabling a receiving node to perform measurements on interference caused by transmissions from at least one transmission point controlled by the transmitting node on receptions at the receiving node. The transmitting and receiving nodes are comprised in a wireless communications system. The transmitting node determines an interference measurement resource, IMR, for the receiving node. The receiving node is expected to measure interference on the IMR. The transmitting node then transmits at least one interfering signal on the IMR. The at least one interfering signal is not expected to be decoded or coherently measured upon by any node served by the transmitting node. | 2015-04-30 |
