摘要： The present disclosure relates to a method and user equipment, UE, in a wireless communication network of performing power scaling on uplink transmission to a receiving radio access node, RAN. In particular, the disclosure relates to a method and user equipment for power scaling on uplink transmissions on a multi-radio access bearer, multi-RAB, wherein a Dedicated Physical Data Channel, DPDCH, and enhanced Data Channels, E-DCHs are configured for uplink transmission from the UE to the receiving RAN. The method comprises determining a total UE transmit power exceeding a predetermined maximum power limit value. The total UE transmit power is reduced to the predetermined maximum power limit value by reducing one or more E-DPDCH gain factors by an equal scaling factor. When a predetermined minimum E-DPDCH gain factor, ‘smallest quantised βed,k value’, is reached for all E-DPDCH gain factors βed,k, and DTX is applied for all E-DPDCHs, the method comprises applying DTX on E-DPCCH.

摘要： A method of operating a terminal in a radio access network may include receiving a transmission of first and second data blocks over respective first and second multiple-input-multiple-output (MIMO) layers during a transmission time interval (TTI). Respective first and second demodulated codewords may be generated corresponding to the transmission of the first and second data blocks, and the first and second demodulated codewords may be decoded. Responsive to failure decoding the first demodulated codeword and success decoding the second demodulated codeword, a negative acknowledgement may be transmitted indicating failure receiving the first and second data blocks. Related terminals are also discussed.

摘要： It is presented a method, performed in a receiver device, for decoding transmissions of a set of coded information bits from a transmitter. The method comprises the steps of: deriving received symbols from first received data and second received data; converting the received symbols to sets of soft coded bit estimates; combining the sets of soft coded bit estimates to a combined set of soft coded bit estimates; decoding the combined set of soft coded bit estimates to a set of soft information bit estimates; converting the set of soft information bit estimates to a set of binary bits; determining whether the set of binary bits has been correctly or incorrectly decoded; performing interference cancellation on the received data; and repeating the mentioned steps until either the set of binary bits has been correctly decoded or a predefined maximum number of iterations is reached.

The total UE transmit power is reduced (S32) to the predetermined maximum power limit value by reducing one or more E-DPDCH gain factors by an equal scaling factor. A DPDCH transmission status is determined (S33), whereupon a power scaling procedure is selected (S34) based on the determined DPDCH transmission status. The selected power scaling procedure is applied (S35) on the uplink transmission.

摘要： Embodiments of the present disclosure provide methods and apparatus for configuring additional CPICHs, e.g. third CPICH, fourth CPICH, etc., to support MIMO transmissions of rank three or higher. The additional CPICHs may be configured with two or more power levels. A radio network controller (RNC) sends configuration information for the additional CPICHs to a serving base station in a cell to configure the additional CPICHs. The additional CPICHs can be configured to have a fixed power level, or multiple power levels. When the additional CPICHs are configured with multiple power levels, the base station can select the appropriate power level for each CPICH in dependence on current scheduling decisions in order to reduce inference.
