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.

Abstract: The present invention provides a method for uplink packet scheduling, comprising the following steps: a base station determines types of terminals, and groups the terminals based on types thereof; the base station transmits pre-scheduling indication information and uplink scheduling commands to the terminals in a group with a same type; the base station receives Physical Uplink Shared Channel (PUSCH) transmitted by the terminals on a corresponding uplink sub-frame. The present invention further provides a base station and a terminal. In the above solution provided by this invention, eNB sorts accessed MTC terminals into different types of groups based on types thereof via a high-layer signaling, part of the MTC terminals in a type group are sorted into a scheduling group via a pre-scheduling instruction carried by PDSCH, all the MTC terminals in that group are scheduled via an uplink scheduling command. The solution provided by this invention can obviously reduce the number of times that the base station transmits uplink scheduling commands, and alleviate the burden on the base station of scheduling PUSCH transmission of MTC terminals.
