Abstract (en)
[origin: WO2013181831A1] A technique, comprising: in response to an indication that a communication device is changing its physical location at a rate above a predetermined threshold, selecting for transmissions to said communication device a transmission mode according to which: data symbols are transmitted together with reference symbols according to the same pre-coding as said data symbols; data symbols and reference symbols share a common pre-coding matrix over a plurality of resource blocks; and multi-layer transmissions involve the transmission of reference symbols for a plurality of layers via shared pairs of resource elements using orthogonal cover codes according to which no despreading is required at the communication device.
