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： Wireless transmissions from a user of a spectral resource are sensed by operating receiver equipment within a user equipment to receive signals within a given bandwidth around a given carrier frequency. If the user equipment is not readily capable of analyzing the received signals to ascertain whether the signature pattern of the user is present in the received signals, then it works cooperatively with a remote unit to analyze the received signals to ascertain whether a signature pattern of the user is present in the received signals. Results of the analysis are reported to a main node. The remote unit can provide software to the user equipment and/or perform at least part of the analysis for the user equipment.

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： In one embodiment, a method of scheduling transmissions for a base station in a multi-carrier wireless communication network comprises scheduling initial transmissions of data packets for one or more users on a first carrier, without reserving scheduling capacity on the first carrier for retransmissions. Doing so increases the scheduled capacity of the first carrier for initial transmissions. The method further includes scheduling retransmissions, as needed, for given ones of the data packets on one or more second carriers. The method allows more traffic to be scheduled on the first carrier, meaning that multi-carrier transmissions are less frequently needed to convey all of the traffic targeted to one or more receivers. Those receivers therefore spend more time operating with a reduced receiver bandwidth (as compared to the bandwidth required for receiving more than one carrier), which reduces operating power.

摘要： A base station receives channel quality reports from a plurality of mobile terminals. The channel quality reports from the mobile terminals indicate the signal power of the signals received by the mobile terminals from the base station and one or more interference parameters relating to the power of impairment components contributing to the total impairment of the received signal during a first time interval. The base station computes an estimated channel quality indication for a second time interval subsequent to the first time interval based on expected variations in the powers of the impairment components. The estimated channel quality indication for the second time interval is used by the base station to schedule the mobile terminals and to determine the transmission format.
