Abstract: The present invention relates to a resource allocation method and apparatus, and a signal transmission method, which are applicable to various technical scenarios of 5G New Radio (NR). A method for operating a communication node for resource allocation in a communication network includes: allocating first data and a first pilot for a first type service to a first block period of a first subframe; allocating second data and a second pilot for a second type service to a second block period overlapping with the first block period; and transmitting the first subframe to another communication node. Here, at least one of the second data and the second pilot is allocated to an area to which the first data is allocated.

Abstract: Provided are a machine type communication (MTC) support method and apparatus capable of providing efficient MTC service. First, when a base station transmits a subframe to which an MTC-physical control format indicator channel (PCFICH) is allocated using an MTC-PCFICH code that is cyclic-shifted on the basis of a control format indicator (CFI) to MTC user equipment (UE), the MTC UE detects the MTC- PCFICH from the received subframe by performing blind decoding of a cyclic shift, and detects a region occupied by a legacy physical downlink control channel (PDCCH) on the basis of the detected MTC-PCFICH. Accordingly, it is possible to support efficient MTC service in a Third Generation Partnership Project (3GPP) Long Term Evolution (LTE)-based mobile communication system while maintaining compatibility with a legacy LTE station.
Abstract translation: 提供能够提供有效的MTC服务的机器类型通信（MTC）支持方法和装置。 首先，当基站发送使用基于控制格式指示符（CFI）循环移位的MTC-PCFICH码向MTC用户设备发送了MTC物理控制格式指示符信道（PCFICH）的子帧时 （UE），MTC UE通过执行循环移位的盲解码来检测来自接收到的子帧的MTC-PCFICH，并且基于检测到的MTC-PCFICH检测传统物理下行链路控制信道（PDCCH）所占据的区域。 因此，可以在维持与传统LTE站的兼容性的同时，在第三代合作伙伴计划（3GPP）长期演进（LTE）的移动通信系统中支持有效的MTC服务。

Abstract: Disclosed is a method for configuring a bandwidth for supporting a broadband carrier in a communication system. An operation method of a base station comprises the steps of: configuring a first bandwidth part and a second bandwidth part for a terminal; configuring a reserved resource for the first bandwidth part in a resource area in which the first bandwidth part and the second bandwidth part overlap; and performing an operation of transmitting or receiving a second data channel, which is scheduled to the second bandwidth part, together with the terminal by using the reserved resource. Therefore, the performance of the communication system can be improved.
