摘要： Aspects of the present disclosure provide adaptive radio link monitoring for machine type communication(s) (MTC), enhanced MTC (eMTC), and/or narrowband Internet-of-Things (NB-IoT). In one aspect, a method is provided which may be performed by a user equipment (UE). The method generally includes receiving a first configuration of parameters for receiving downlink control channel signaling, the first configuration of parameters associated with a first coverage level; measuring at least one parameter related to channel conditions; determining one or more dynamic radio link monitoring (RLM) threshold values for the at least one parameter based, at least in part, on the first configuration of parameters; and performing RLM functions based on the one or more dynamic RLM threshold values. The threshold may comprise early out thresholds that occur before out-of-sync (OOS) or in-sync thresholds. The thresholds may be determined using lookup tables.

摘要： Apparatus and methods for recovering data from a control channel in wireless communications. A decoded codeword is obtained by convolutional decoding, the decoded codeword containing an estimate of a CRC codeword. A first syndrome for the CRC codeword is computed utilizing a parity check matrix of the CRC code. If the first syndrome is non-zero, the apparatus determines a location S and a length K of an error pattern within the CRC codeword based on a known interference period between transmission and reception, during which an error burst is assumed. A linear equation system is formed based on S, K and the parity check matrix of the CRC. The apparatus determines a solution of the linear system, wherein the solution includes an estimated error pattern. A recovered codeword can be determined by removing the estimated error pattern from the decoded codeword.
