摘要： To communicate wireless handover events, a communications device associated with a serving cell of a cellular network determines, based on at least one or more first measurement results indicative of cell quality parameters of a plurality of cells of the cellular network, a first handover event associated with a first one of the cells, initiates communication of a first handover message indicative of the determined first handover event to a network entity of the cellular network, and, based on at least one or more second measurement results, determines a plurality of further handover events associated with respective ones of the cells, resulting in a plurality of pending handover events waiting to be communicated to a network entity of the cellular network. The communications device also determines a priority order for at least a subset of the pending handover events. The subset includes handover events associated with different cells.

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.
