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.

[0030] In this specification, an MTC terminal may refer to a terminal supporting low cost (or low complexity), a terminal supporting coverage enhancement, and the like. In this specification, an MTC terminal may refer to a terminal supporting low cost (or low complexity), coverage enhancement, and the like. Alternatively, in this specification, an MTC terminal refers to a terminal to be...

Abstract

Provided is 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 is for a machinetype communication (MTC) application defined in a 3GPP LTE / LTE-A system. In particular, the embodiments of the present invention provide a method configured with a search space to monitor the DCI usedfor sending the SC-MCCH transmission resource distribution information and the change information.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application Nos. 10-2016-0103189 and 10-2017-0081324 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] The present embodiment relates to a single-cell Point-to-Multipoint ( SC-PLM) approach. 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 band having a limited channel bandwidth of 6 PRB corresponding to th...
