Abstract:
A method for receiving information for interference cancellation of a mobile station (MS) is disclosed. The method is performed by the MS and includes receiving a restricted virtual radio network temporary identifier (V-RNTI) set including a plurality of V-RNTIs for interference signal cancellation from a serving base station (BS), wherein each of the plurality of V-RNTIs is associated with one or more RNTIs of one or more MSs served by a neighboring cell (hereinafter, “neighboring MS”), and receiving downlink control channel including a cyclic redundancy check (CRC) bit scrambled by at least one V-RNTI of the restricted V-RNTI set, for the neighboring MS, using the at least one V-RNTI, wherein, if two or more neighboring MSs having RNTIs associated with a specific V-RNTI among the plurality of V-RNTIs are scheduled at the same time, the specific V-RNTI is used only for downlink control channel for one of the two or more neighboring MSs.
Abstract:
A method of performing intra-frequency cell measurement by a user equipment (UE) in a wireless communication system is disclosed. The method includes determining a measurement gap for the intra-frequency cell measurement based on downlink control information received from an eNB, and performing the intra-frequency cell measurement for a neighboring cell during the measurement gap. The measurement gap corresponds to one or more downlink subframes other than a downlink subframe having downlink data for the UE indicated by the downlink control information.

Abstract:
The present disclosure provides a method for a terminal to receive a physical downlink shared channel (PDSCH) in a wireless communication system supporting a narrow band-internet of things (NB-IoT). Specifically, the terminal receives a first physical downlink control channel (PDCCH) including first downlink control information (DCI) from a base station and receives a first PDSCH on the basis of the first DCI. Here, the first PDSCH may include indication information indicating whether a multi transport block is scheduled. The terminal receives a plurality of PDSCHs from the base station, wherein at least one PDSCH of the plurality of PDSCHs may be received without receiving a separate DCI according to the indication information.
