The user equipment (910 is configured to determine, for a data transmission a mapping form a demodulation reference signal (DMRS) to a PNT-RS. A DMRS resulting signal is generated from a subset of DMRS for a first resource element in a subcarrier.

The data transmission is transmitted using the DMRS resulting signal and the PNT-RS.

Abstract: Techniques are disclosed whereby a signal is transmitted from a wireless network to a wireless device, requesting automatic repeat-request, ARQ, feedback for certain indicated ARQ processes. This asynchronous approach addresses a problem with irregular ARQ feedback for dynamic time-division-duplexing, and also allows for relaxed processing-time constraints in the wireless device. An example method, in a wireless device, comprises receiving (610) from a wireless communication network, in a first transmission-time interval, a request for ARQ feedback, the request indicating one or more ARQ processes. The example method further comprises transmitting (620) to the wireless communication network, in a second transmission-time interval, ARQ feedback information for each of the one or more indicated ARQ processes.

Abstract: A radio-network node handling a data transmission to a wireless device transmits data over a number of subframes to the wireless device, and a respective control part, associated with the data of each respective subframe, the respective control part comprising a feedback index indicating a transmission time of a feedback indication.

The radio-network node receives the feedback message and then decides whether or not to retransmit any of the subframes based on the feedback indication therein.
