Method and apparatus for channel estimation and data decoding in wireless communication system
First Claim
1. A method of a terminal in a wireless communication system, the method comprising:
- receiving, from a base station, configuration information on a physical resource block (PRB) bundling via higher layer signaling, the configuration information including first information indicating that a precoding resource block group (PRG) size is indicated via downlink control information (DCI) and second information including one or more PRG size values among a set of PRG size values which includes 2, 4, and an allocated bandwidth for the terminal;
receiving, from the base station, the DCI including a PRG size indicator on a physical downlink control channel (PDCCH), wherein the PRG size indicator is set as a value corresponding to a PRG size value which is one of the one or more PRG size values; and
identifying the PRG size based on the PRG size indicator.

Abstract
A communication method and system that combine the internet of things (IoT) technology with fifth generation (5G) communication systems supporting a higher data rate after fourth generation (4G) systems are provided. The present disclosure may be applied to intelligent services, such as smart homes, smart buildings, smart cities, smart or connected cars, healthcare, digital education, retail businesses, and security and safety related services on the basis of 5G communication technologies and IoT related technologies. A method of a terminal in a wireless communication system to improve DMRS channel estimation performance is provided. The method includes receiving first information configuring a physical resource block (PRB) bundling size indication based on second information, receiving the second information indicating the number of at least one PRB, if the PRB bundling size indication is configured, and estimating the channel state based on an assumption that the same precoding is applied to the at least one PRB based on the second information.
