Embodiment Construction

[0029] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. When adding reference numerals to elements in each drawing, the same reference numerals will be used to designate the same elements even though they are shown in different drawings, if possible. Also, in the following description of the present disclosure, when it is determined that the description may make the subject matter of the present disclosure rather unclear, a detailed description of known functions and configurations incorporated herein will be omitted.

Abstract

Provided are a method of supporting Single Cell Point-to-Multi-point (SC-PTM) for a Bandwidth reduced Low complexity / Coverage Enhancement (BL / CE) terminal or an NB-IoT terminal, which are for a Machine Type Communication (MTC) application defined in a 3GPP LTE / LTE-A system. The method may include receiving configuration information relating to an NPDCCH search space from a base station wherein theNPDCCH search space is separately configured to receive scheduling control information for the multicasting control channel; receiving the scheduling control information for the multicasting controlchannel through the NPDCCH search space configured based on the configuration information; and receiving the multicasting control channel based on the scheduling control information, wherein the configuration information is received through higher layer signaling.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application Nos. 10-2016-0103189 and 10-2017-0081319 filed on August 12, 2016 and June 27, 2017, which are incorporated by reference for common purposes Herein, as if fully described herein. technical field [0003] This embodiment relates to a method for supporting single-cell point-to-multipoint (SC-PLM) for NB-IoT terminals defined in the 3GPP LTE / LTE-Advanced system. Background technique [0004] In 3GPP Release 12 / 13, bandwidth-reduced low-complexity (BL) terminal technology and coverage-enhanced (CE) terminal technology have been standardized. Low Complexity (LC) terminals mean terminals targeting low-end applications with low margins, low speed and low latency sensitivity, such as certain Machine Type Communication (MTC) terminals. LC terminals have reduced Tx and Rx capabilities compared to other kinds of terminals. The BL terminal operates in an LTE system...
