摘要： Systems and methods related to providing spatial reuse gain as well as Multiple-Input-Multiple-Output (MIMO) gains in a combined cell of a heterogeneous cellular communications network are disclosed. In one embodiment, a method of operation of a wireless device includes receiving node-specific pilot signals from transmission nodes in a combined cell, where each node-specific pilot signal is transmitted by a different transmission node in the combined cell. The method further includes generating channel measurements based on the node-specific pilot signals. The channel measurements include a separate channel measurement for each transmission node based on the node-specific pilot signal transmitted by the transmission node. The method further includes selecting a desired combination of nodes from the subset of the transmission nodes based directly or indirectly on the channel measurements and providing an indication of the desired combination of nodes to the central control node for the combined cell.

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 and controlling node (500) to control a signal combining operation performed on uplink radio signals transmitted from a User Equipment, UE, in a combined cell served by multiple radio nodes (502). Signal quality information (SQ) is received from the UE indicating a signal quality measured by the UE on a node-specific probing pilot signal (PS1-PS4) transmitted from each of the multiple radio nodes, and a subset (RN2-RN3) of the multiple radio nodes is selected based on the received channel quality information. The signal combining operation is then performing (204) on the uplink radio signals received by the selected subset of the multiple radio nodes. Thereby, the performance of the signal combining operation can be improved.
