摘要:
Interference is reduced between two radio communication systems. A first radio communication system uses a first and a second frequency ranges which are separated by a duplex gap. A second radio communication system uses a third radio frequency range which forms part of the duplex gap. The first and second radio communication systems exchange information in order to establish an a priori knowledge about a connection on the network side. The a priori knowledge includes the radio transmission resources of the first frequency range provided on the radio communication system side and of the second frequency range and the radio transmission resources of the third frequency range (FB3) desired for call setup and completion. Radio transmission resources are selected depending on the a priori knowledge at the second radio communication system in order to reduce interferences between the first and second radio communication systems.

After a maximum noise rise for a cell is set, a maximum noise rise for each mobile station is allocated within the cell. The actual noise rise from each mobile station within the cell is measured at a base station and signaled to a network. When the cell uses enhanced dedicated channel (E-DCH), the contribution to noise rise of E-DCH signaling is determined and received signal code power (RSCP) at the base station is measured. The RSCP measurement is decoded to determine contributions from mobile stations within and outside the cell; contributions from mobile stations within the cell are calculated; and the network is notified of the measured noise rise. In addition a compensation value may be applied to compensate for temperature induced noise.

A user terminal receives at least one signal with information depending on a location of the user terminal. The user terminal processes the at least one signal for providing data related to the location while it is in a cell of an accessible private base station and saves the data as a reference data. After that, the user terminal receives at least one signal with information depending on the location of the user terminal and a broadcast from a private base station. The user terminal processes the at least one signal for providing data related to a location of the user terminal and compares the data and a reference data with each other. The controller enables a contact to the private base station if the data and the reference data match each other and, otherwise, disables a contact to the private base station.

A method includes handing over a user equipment from a first network access node to a second network access node and, at the second network access node, not considering the first network access node as a handover candidate from the second network access node until at least one of: (a) an amount of time since the hand over from the first network access node exceeds a first threshold amount; (b) there is a change in a channel condition between the user equipment and the first access node that exceeds a second threshold amount.

Codes are assigned and scheduled for data transmissions, between a radio station and at least one subscriber station, over a wireless interface of a radio communication system, in such a way that both for transmissions in the upward direction (uplink), from subscriber stations to the radio station, and also for transmissions in the downward direction (downlink), from the radio station to subscriber stations, the lowest possible signal-to-average ratio can be achieved.
