摘要： The present disclosure provides a method in a wireless device for initiating a handover from a source base station to a target base station. The method includes calculating a power offset indicative of a difference between a receiving power from the target base station and a receiving power from the source base station. A Time Division Duplex (TDD) configuration difference is obtained between a TDD configuration of the target base station and a TDD configuration of the source base station. A TDD offset is calculated based on the TDD configuration difference and an uplink-downlink traffic model of the wireless device. The handover is initiated based on a combination of the power offset and the TDD offset exceeding a threshold. The present disclosure also provides a wireless device, a method in a base station and a base station.

摘要： 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 assigned first set of PUCCH resource indices for PDSCHs received in the DL subframes of the first subset of DL subframes and in an order of the assigned second set of PUCCH resource indices for PDSCHs received in the DL subframes of the second subset of DL subframes. The present disclosure also relates to a UE and BS for respectively reporting and receiving HARQ ACK/NACK for PDSCHs in TDD configurations.
