Abstract: An operation method of a terminal that receives a DRS in a mobile communication system operating in an unlicensed spectrum includes: receiving an SS/PBCH block included in the DRS; checking at least one monitoring occasion for a PDCCH for receiving RMSI on the basis of a PBCH included in the SS/PBCH; monitoring the at least one monitoring occasion and detecting the PDCCH for receiving the RMSI; and receiving a PDSCH including the RMSI on the basis of the detected PDCCH, wherein the at least one monitoring occasion is set to at least one symbol among symbols in front of the PDSCH and symbols behind the PDSCH. Accordingly, the DRS and data may be reliably transmitted and received in the mobile communication system operating in the unlicensed spectrum.

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: Disclosed are a measurement method and a measurement apparatus for supporting mobility in a communication system. An operation method of a terminal may comprise receiving, from a base station, control information including first information indicating one or more physical uplink shared channel (PUSCH) interlaces configured in an unlicensed band; identifying frequency resources corresponding to the one or more PUSCH interlaces; and transmitting a PUSCH to the base station using the frequency resources of the unlicensed band. Thus, the performance of the communication system can be improved.
