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 radio network controller is operable in both a unicast signaling mode and a bi-cast signaling mode. In unicast signaling mode, the radio network controller is operable to send radio resource control signals to a mobile station through a serving cell. The radio network controller is operable to go into bi-cast signaling mode during a hard handover. In the bi-cast signaling mode, the radio network controller is operable to send radio resource control messages to the mobile station through both the current serving cell and a target cell. The mobile station is configured to listen to both the current serving cell and the target cell for radio resource control messages. User data, however, is transmitted only from the current serving cell to the mobile station.

摘要： In a mobile communication network comprising a pico base station and macro base station with overlapping coverage areas, the pico base station transmits a supplemental synchronization signal to enable synchronization when the mobile terminal is operating within a link imbalance zone. The supplemental synchronization signal is transmitted using different time, frequency, and/or code resources from the primary and/or secondary synchronization signals to differentiate and separate the supplemental synchronization signals.

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.

摘要翻译： 在一个实施例中，一种在多载波无线通信网络中为基站调度传输的方法包括：在第一载波上调度一个或多个用户的数据分组的初始传输，而不在第一载波上保留用于重发的调度能力。 这样做增加了初始传输的第一载波的调度容量。 该方法还包括根据需要针对一个或多个第二载波上的给定数据分组来调度重传。 该方法允许在第一载波上调度更多业务，这意味着不太需要多载波传输来传送针对一个或多个接收机的所有业务。 因此，这些接收机花费更多的时间以减少的接收机带宽（与接收多于一个载波所需的带宽相比）来降低操作功率。

摘要： A radio network node and a method therein, for controlling usage of RAT and bandwidth in a radio communication system. The method includes allocating a first RAT to a first bandwidth, allocating a second RAT to a second bandwidth, and allocating the first and second RATs to a third bandwidth comprising a part of the first bandwidth and/or a part of the second bandwidth. When the first RAT has a higher load than the second RAT, the method includes transmitting data for the first RAT in both the first third bandwidths, transmitting data for the second RAT only in the second bandwidth, and transmitting common control signals and/or pilot signals for the first RAT in the first and third bandwidths.
