摘要： Data may be transmitted from a RAN node to a wireless terminal using a MIMO antenna array. A plurality of unmapped symbol blocks may be generated. Symbols of a first one of the plurality of unmapped symbol blocks may be mapped to first and second mapped symbol blocks so that the first mapped symbol block includes symbols of the first unmapped symbol block and so that the second mapped symbol block includes symbols of the first unmapped symbol block. The symbols of the first and second mapped symbol blocks may be precoded to provide precoded symbols of respective first and second MIMO precoding layers using a MIMO precoding vector. Each of the precoded symbols of the first and second MIMO precoding layers may be transmitted through the MIMO antenna array to the wireless terminal using a same TFRE. Related devices and terminals are also discussed.

摘要： A control node is configured to control a SIR-target for use by the radio network node when operating an Inner Loop Power Control. The radio network node receives a primary stream and a secondary stream while employing HSUPA MIMO. The radio network node detects a first indication of number of HARQ re-transmissions. The first indication is related to the primary stream. The radio network node detects a second indication of number of HARQ re-transmissions. The second indication is related to the secondary stream. The radio network node configures an Iub frame based on one or more of the first and second indication. The control node is configured to perform OLPC. Subsequently, the control node receives the Iub frame from the radio network node and extracts the first and/or second indication/s from the Iub frame. Next, the control node determines the SIR-target based on the first indication.
