Abstract: 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.

Abstract: 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.

Abstract: A vacuum suction head may include a holder including a through hole formed therein, a suction pad surrounding at least a portion of a side surface of the holder, and a packing pad on a lower surface of the holder. The suction pad may protrude below a lower surface of the holder. The packing pad may include a cutout part. The cutout part may allow a space between the suction pad and the packing pad such that the space and the through hole may be in fluid communication with each other.

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: 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.

Abstract: 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.

Abstract: 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.
