1. A method used in a User Equipment, UE, for reporting Hybrid Automatic Repeat Request, HARQ, acknowledgement, ACK, /non-acknowledgement, NACK, for Physical Downlink Shared Channels, PDSCHs, in dynamic time division duplex, TDD, configurations, the method comprising:
receiving a plurality of PDSCHs in DownLink, DL, subframes associated with an UpLink, UL, subframe and indicated by a DL reference TDD configuration;
for each of the received PDSCHs,
reporting HARQ ACK/NACK by at least partially using PUCCH resources indicated by Downlink Control Information, DCI, and/or Radio Resource Control, RRC, signaling, dividing the DL subframes into a first subset of DL subframes and a second subset of DL subframes, wherein the first subset of DL subframes is also indicated by an UL reference TDD configuration;
assigning a set of Physical Uplink Control Channel, PUCCH, resource indices based on resources used in transmission of Physical Downlink Control Channels, PDCCHs, corresponding to the PDSCHs received in the DL subframes of the first subset of DL subframes;
for each of the PDSCHs received in the DL subframes of the first subset of DL subframes, reporting HARQ ACK/NACK using PUCCH resources in an order of the assigned set of PUCCH resource indices; and
for each of the PDSCHs received in the DL subframes of the second subset of DL subframes, reporting HARQ ACK/NACK using PUCCH resources indicated by DCI and/or RRC signaling.
