Abstract
The present disclosure relates to 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. In the method, a plurality of PDSCHs are received in DownLink (DL) subframes associated with an UpLink (UL) subframe and indicated by a DL reference TDD configuration. The DL subframes are divided into a first subset of DL subframes and a second subset of DL subframes. The first subset of DL subframes is also indicated by an UL reference TDD configuration. A first set of Physical Uplink Control Channel (PUCCH) resource indices are assigned 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. A second set of PUCCH resource indices are assigned based on resources used in transmission of PDCCHs corresponding to the PDSCHs received in the DL subframes of the second subset of DL subframes. For each of the received PDSCHs, HARQ ACK/NACK is reported by using PUCCH resources in an order of the…
