Abstract
Methods and user equipment (UE) for data demodulation. A UE comprises a receiver (Rx), a transmitter (Tx), a demodulator, a decoder, a processor, and a memory. An order message can be received by the receiver from a radio network node. The order message orders the UE to utilize both additional pilots and common pilots. In response to the receiver receiving the order message, the transmitter may return an ACK message to the radio network node. The receiver may also be configured to receive data from the radio network node. The memory stores computer program code which, when run in the processor, causes the demodulator to demodulate received data utilizing additional pilots in addition to common pilots. Furthermore, the memory and the computer program code are configured to, together with the processor, cause the demodulator to demodulate received data utilizing only common pilots when the decoder is unsuccessful in decoding received data demodulated by utilizing additional pilots in addition to common pilots.
