A method, performed by a user equipment (UE), of transmitting and receiving signals in a wireless communication system, according to an embodiment, includes receiving a logical channel release request from a next-generation node B (gNB), determining a logical channel to release, an operation mode of the logical channel to release, and whether a packet data convergence protocol (PDCP) layer apparatus connected to the logical channel is re-established, based on the logical channel release request, and performing PDCP data recovery based on the determination result.

Performing cell selection procedure based on supplementary uplink (SUL) technology

A memory system includes a memory device comprising plural memory groups, and a controller configured to independently set or adjust a page close time or a page open time for a row or a page in each of the plural memory groups based on whether there is a request to be transferred into each of the plural memory groups.

Memory system and operation method thereof

Methods and apparatuses are provided in a wireless communication system in which a radio resource control (RRC) message is received to change or release a secondary cell group (SCG). A re-establishment for a radio link control (RLC) entity of a terminal is performed based on the RRC message. A packet data convergence protocol (PDCP) data recovery is performed based on the RRC message. Performing the PDCP data recovery includes selectively transmitting a PDCP protocol data unit (PDU) previously submitted to the re-established RLC entity, for which a successful delivery has not been confirmed by the re-established RLC entity.

Method and apparatus for transmitting and receiving data in wireless communication system

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.

Method and apparatus for wireless communication in wireless communication system

Provided is a method for performing uplink data compression (UDC) by a user equipment (UE). The method includes receiving configuration information on UDC; generating a first UDC packet by compressing uplink data, based on the configuration information on UDC; transmitting the first UDC packet; receiving, from the base station, packet data convergence protocol (PDCP) layer control information including checksum error information about whether a checksum error has occurred in the first UDC packet; and resetting a UDC buffer used in compressing the uplink data, based on the PDCP layer control information.

A cache system includes a cache memory having a plurality of blocks, a dirty line list storing status information of a predetermined number of dirty lines among dirty lines in the plurality of blocks, and a cache controller controlling a data caching operation of the cache memory and providing statuses and variation of statuses of the dirty lines, according to the data caching operation, to the dirty line list. The cache controller performs a control operation to always store status information of a least-recently-used (LRU) dirty line into a predetermined storage location of the dirty line list.

Data caching methods of cache systems

A method of UE includes receiving a radio resource control (RRC) message for configuring bandwidth parts (BWPs) of a serving cell, receiving a physical downlink control channel (PDCCH) indicating activation of a first BWP, performing a BWP switching to the first BWP indicated by the PDCCH, and starting a first downlink BWP timer associated with the first BWP. A UE includes a transceiver, and at least one controller coupled with the transceiver, the at least one controller configured to receive an RRC message for configuring BWPs of a serving cell, receive a PDCCH indicating activation of a first BWP, perform a BWP switching to the first BWP indicated by the PDCCH, and start a first downlink BWP timer associated with the first BWP.

Communication method and apparatus for bandwidth part switching in wireless communication system

Provided is a method, performed by a user equipment (UE), of processing data in a wireless communication system, the method including: determining a format for buffer status report based on a buffer status of each of logical channel groups when the UE receiving an uplink transmission resource from a base station determines to report the buffer status to the base station; allocating, to each of the logical channel groups, a transmission resource remaining after excluding, from the uplink transmission resource, a transmission resource used for reporting the buffer status of the determined format; and re-determining the format for the buffer status report based on the buffer status of each of the logical channel groups after the allocating.

Method and device for processing data in wireless communication system

Methods for performing a random access procedure by a terminal and a base station in a wireless communication system, a terminal, and a base station are provided. The method for performing a random access procedure by a terminal in a wireless communication system includes selecting a physical random access channel (PRACH) resource from one or more PRACH resources; transmitting, to a base station, a random access preamble based on the selected PRACH resource; identifying a random access radio network temporary identifier (RA-RNTI) based on information associated with the selected PRACH resource, wherein the information includes identity information for an uplink used for the random access preamble transmission; and monitoring a control channel for a random access response (RAR) based on the RA-RNTI.

Cache systems of memory systems and data caching methods of cache systems

An operating method of a memory controller to update metadata using journaling data in a short time during a booting operation, and to maintain reliability of the updated metadata. The operating method of a memory controller includes loading metadata into sub-regions of a buffer memory, updating the metadata using journaling data in a state that error correction code (ECC) functions of memory controller for the sub-regions are disabled, generating a first parity data of data stored in the first sub-region, and enabling the ECC function of the first sub-region, after the first parity data is generated.

Operating method of memory controller, memory controller, and storage device

Disclosed is a 5G or a pre-5G communication system provided to support a higher data transmission rate than a system after a 4G communication system such as LTE.

Method and apparatus for performing handover in wireless communication system

Provided is a user equipment method of transmitting and receiving data in a wireless communication system, comprising receiving a request for a packet data convergence protocol (PDCP) data recovery from an upper layer, determining at least one PDCP packet data unit (PDU), previously submitted to a re-established radio link control (RLC) entity, for which a successful delivery has not been confirmed by a lower layer, and performing a retransmission of the determined at least one PDCP PDU.
