Abstract: PROBLEM TO BE SOLVED: To more exactly reduce multi-access interference by appropriately generating an interference replica signal corresponding to the state of a signal to be handled on each of stages. SOLUTION: In a multi-user receiver utilizing a multi-stage interference canceler, the respective stages for each of first to k-th users are provided with searchers 4 S1U1-4 S3Uk for detecting respective multi-paths and path information is acquired from the same input received signal as an input received signal supplied to IGU (interference replica generating units) 5 S1U1-5 S3Uk of respective stages. In the IGU 5 S1U1-5 S3Uk, on the basis of path information supplied from the searchers 4 S1U1-4 S3Uk, RAKE synthesizing receiving or replica signal generation is performed. On the first and second stages, the interference replica signals of respective users are generated and on the third stage, received information data are acquired from the received signal, from which multi-access interference is rejected by these interference replica signals, by RAKE synthesizing receiving.

Abstract: The invention discloses a method (400) for use in a first node (110) in a wireless access communication system (100). According to the method, the first node controls (405) traffic to and from users, UEs (120), within a certain area in the system, a cell, and the first node is equipped (410) with a plurality of transmit antennas (111,113). The first node can employ (415) a variety of multi antenna transmit modes for down link transmissions, i.e. transmissions to the UEs, and the first node can carry (420) out a so called Random Access (RA) procedure with UEs which do not have a dedicated up link resource, i.e. a resource to the eNodeB. According to the method, one and the same down link multi antenna transmit mode is used by the first node during the RA procedure.

Abstract: A control signal data processing load associated with mobile terminals currently having a connection with a radio access network is regulated. The connection is terminated when the control processing cost for maintaining the connection exceeds the benefit of maintaining the connection to achieve shorter access latency. A connection activity level is determined for current connections between multiple mobile terminals and a base station. A current data processing load in the base station associated with the mobile terminal control signaling is calculated. A decision is made whether one or more of the mobile terminals is likely to request a handover of its respective connection to a neighboring base station. Based on the current load, the likelihood of requesting handover of the respective connection, and the connection activity level determined for the respective connection, a decision is made whether to terminate the respective connection.

Abstract: A single user detection (SUD) unit is used to detect the dedicated physical control channel (DPCCH) of a received signal. This reduces interference from other users, provides higher quality for the control channel detection, and achieves short processing delays. Consequently, the detected control channel being used to enhance the detection of the data channel part of the received signal. The data detection process performed on the data channel being enhanced by using channel estimate information generated by the SUD unit. The data detection process is performed by a Multi-user detector, a single user detector or any conventional detector.
