摘要： The invention provides improved suppression of co-channel interference (CCI) in a wireless cellular communications system where at least two base stations use the same transmit frequency. The method according to the invention uses the difference in synchronization times between the home signal and the CCI signal to suppress the CCI signal. The method uses a modified known method of estimating time of arrival (TOA) to estimate sync positions for the CCI signal. This enables the use of interference cancelling methods in communications systems using un-synchronized base stations. Receiver performance is improved, which in turn improves data throughput and received speech quality, since interfering signals from base stations using the same frequency can be suppressed.

摘要： Methods and apparatus for changing the transmission/reception setup of a base station (BS) in a communication network to another transmission/reception setup (such as one using fewer transmit antennas and/or lower channel bandwidths) without affecting communication with user equipments involve “replacing” the existing BS with a “virtual” BS that has the other transmission/reception setup. Replacement can be performed by, for example, ramping down the power of the existing, or first, BS, which has a respective first cell identification (ID), and simultaneously ramping up the power of the virtual, or second, BS, which has a respective second cell ID.

摘要： A method is disclosed of scheduling up-link transmissions for a number of terminals of a wireless communication system into a number of groups, wherein each group comprises terminals intended for simultaneous up-link transmission during a respective period of time. A subset metric may be calculated for each of a number of subsets of terminals based on transmissions received from the terminals of the subset. The subset metric is indicative of a simultaneous transmission suitability measure for the terminals of the subset. The subsets may be processed in subset metric order, starting with the subset having a subset metric indicating a least suitability of simultaneous transmission. During the processing, each terminal of the subset that is not already scheduled in a group may be scheduled in a group that does not already comprise another terminal of the subset. Information indicative of the period of time during which a scheduled terminal is intended to transmit may be transmitted to each of the scheduled terminals. Corresponding computer program product, scheduler and arrangement are also disclosed.

摘要： A method of operating a terminal of a wireless communication network is disclosed, wherein the terminal operates according to a discontinuous reception mode. The wireless communication network comprises one or more wireless network nodes having at least first and second downlink transmission modes, the first downlink transmission mode comprising normal operation of a particular network node and the second downlink transmission mode comprising restricted downlink transmission of the particular network node and being applicable when the number of active terminals in the cell associated with the particular network node is less than or equal to a second mode threshold value. The method comprises detecting a cell identity for a cell associated with a wireless network node of the wireless communication system, determining a current downlink transmission mode of the wireless network node as the first or second downlink transmission mode, and adapting a time pattern based on the determined current downlink transmission mode, wherein the time pattern specifies when a receiver of the terminal is turned on. Corresponding computer program product and arrangement are also disclosed.
