    摘要： The invention relates to Coordinated Scheduling for a Time Division Duplex (TDD) network. In a method for User Equipment (UE) scheduling by a base station in a TDD network, the base station receives scheduling decision from at least one neighboring cell of the base station, and schedules a UE among a plurality of UEs in the serving cell of the base station based on the scheduling decision from the at least one neighboring cell and based on smart antenna information. The inter-cell interference is suppressed and therefore the network performance is improved.

    摘要： A minimum value or range for a transmit power gain factor is determined that controls the transmit power level over an enhanced uplink data channel relative so as to ensure delivery of a minimum data service requirement over the enhanced uplink data channel. The minimum value or range for the enhanced uplink data channel power gain factor may be determined based on a selected enhanced uplink transmission format and/or a maximum number of allowable transmission attempts over the enhanced uplink data channel for a communications session so that the required Quality of Service (QoS) for the communications session can be fulfilled and an expected uplink coverage gain can be reached. The minimum value or range for the enhanced uplink data channel power gain factor is also compatible with other techniques to increase enhanced uplink coverage such as autonomous retransmission and improved L2 techniques.

    摘要： The present invention relates to an arrangement and a method in a user equipment of saving radio resources in a communication network system comprising a communication network node (15) communicating withto one or more user equipments (18) on uplink (17) and downlink (16) data channels over a radio interface, whereby a transmission power 5 value on said uplink data channel (17) is determined by adding a power offset value to a pre-determined reference power value. A carrier-to-interference (C/I) value on said uplink data channel (17) is determined and said power offset value is then determined based on said determined carrier-to-interference value, whereby said power offset value is determined in said user equipment (18) instead of being received over said radio interface 10 from said communication network node (15).
