Abstract: Examples of the present invention provide a method for allocating Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) channel resources supporting transmit diversity and channel selection. The method includes: receiving, by a UE, Physical Downlink Control Channel (PDCCH) information and Physical Downlink Shared Channel (PDSCH) data from a base station through two Carrier Components (CCs); obtaining, by the UE according to specific indication information, Physical Uplink Control Channel (PUCCH) channel resources required for transmitting HARQ-ACK feedback information using a transmit diversity technique; and transmitting, by the UE, the HARQ-ACK feedback information on the obtained PUCCH channel resources adopting the transmit diversity technique. According to the method provided by the examples of the present invention, it is possible to allocate HARQ-ACK channel resources to the UE reasonably and avoid waste of channel resources in the premise that channel selection and SORTD technique are supported.

Abstract: The present disclosure provides a method for RLM and a corresponding UE. The method comprises the steps of: determining, by a UE and on a carrier used for RLM, whether a reference signal transmitted by a base station for RLM is received in any subframe; performing RLM based on the reference signal if the reference signal transmitted by the base station is received in any subframe; and, determining, according to a result of RLM, whether link failure is detected. With the solutions, a link state capable of accurately reflecting the actual link quality can be acquired, so that a higher layer of a UE can timely make a decision on link failure or link recovery.
