Abstract: Methods and apparatuses are provided in a wireless communication system. Packet data convergence protocol (PDCP) configuration information that configures a PDCP entity of the terminal to use an uplink data compression (UDC) is received from a base station. The PDCP entity generates a UDC header and a UDC data block, based on the PDCP configuration information. The PDCP entity ciphers the UDC header and the UDC data block. The PDCP entity generates PDCP data including a PDCP header, the ciphered UDC header and the ciphered UDC data block. The generated PDCP data is transmitted to the base station. A header compression is not configured in case that the UDC is configured.

Abstract: The present disclosure relates to a communication scheme and system for converging a 5th generation (5G) communication system for supporting a data rate higher than that of a 4th generation (4G) system with an internet of things (IoT) technology. The present disclosure is applicable to intelligent services (e.g., smart home, smart building, smart city, smart car, connected car, health care, digital education, retail, and security and safety-related services) based on the 5G communication technology and the IoT-related technology. The present disclosure provides a method for preventing a legacy terminal from camping on an enhanced LTE (eLTE) base station that is connected to only a next generation (NG) core by combining a legacy information element (IE) and a new IE carried in system information broadcast by the base station in a next generation mobile communication system.

Abstract: Disclosed are a communication technique for merging IoT technology with a 5G communication system for supporting a data transmission rate higher than that of a 4G system and a system therefor. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security, and safety related services, and the like) on the basis of 5G communication technology and IoT-related technology. The present invention relates to operations of a terminal and a base station in a mobile communication system. The present invention provides a method by which a terminal re-establishes a PDCP in a wireless communication system, the method comprising the steps of: receiving a message including PDCP re-establishment information on a DRB from a base station in which an RRC connection is set up; checking whether the PDCP re-establishment information includes configuration information of an SDAP layer; and determining whether to perform a PDCP re-establishment procedure for changing the DRB operating as a PDCP of a first system into a PDCP of a second system on the basis of the checking result.
