Embodiments herein disclose a method for handling PDCP operation by an EN-DC capable UE in a wireless communication system. The method includes receiving, by an EN-DC capable UE, LTE PDCP PDUs from the LTE RLC entity by a receiver LTE PDCP entity upon re-establishing LTE RLC entity based on the indication that indicates a PDCP version change from a LTE PDCP to a NR PDCP. Further, the method includes processing the LTE PDCP PDUs at the receiver LTE PDCP entity using a LTE format. Further, the method includes reestablishing the receiver LTE PDCP entity and a transmitter LTE PDCP entity of the UE.

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing an adaptive bundling transmission in wireless communication system, the method comprising: generating a uplink (UL) data to be transmitted for an uplink grant of a Hybrid-ARQ (HARQ) process; performing a new HARQ transmission of the UL data with resetting a counter of the HARQ process, performing a HARQ retransmission of the UL data, if the new HARQ transmission of the UL data fails, wherein the counter is counted each time a HARQ transmission of the UL data fails, wherein if the counter is equal to or larger than a threshold, the HARQ retransmission of the UL data is performed with bundling transmission.

Disclosed is a synchronisation method and apparatus. The method includes steps described below. A control plane (CP) entity determines content to be counted, an object and a reporting policy for performing a synchronisation operation, where the synchronisation operation includes at least one of: a working status synchronisation operation or a resource status synchronisation operation; and the CP entity sends a request for the synchronisation operation to a user plane (UP) entity, where the request carries configuration information about the content to be counted, the object and the reporting policy for the synchronisation operation. Further disclosed are a network element and a computer-readable storage medium.

An electronic device and an operation method of an electronic device are provided. The electronic device includes a memory storing an application, an edge enabler client (EEC), and/or a user equipment (UE) selection route policy (USRP) rule used for producing a session used by the electronic device, a communication circuit used for a communication connection between the electronic device and at least one of a first server, a plurality of second servers, or a third server disposed outside the electronic device, via a base station, and a processor, the application being configured to perform, in the electronic device, one or more services corresponding to an application executable in the third server, and the processor is configured to identify identification information of the EEC and identification information of an EEC included in the USRP rule, in response to activation of the EEC, to set a first packet data unit (PDU) session.

A method for optimizing the processing of logical channels when multiple transport formats are to be served is provided. In certain aspects, instead of filling sequentially each transport format one by one, the protocol packets to be transmitted by the transport block are concurrently constructed. This may be accomplished, for instance, by taking into consideration the requirements of the data (for example, latency and reliability) to be transmitted as well as the characteristics of the available transport format (for example, size, expected channel quality, transmission length, etc.).

A method and apparatus for flushing a hybrid automatic repeat request (HARQ) buffer in a wireless communication system is provided. A user equipment (UE) receives information on multiple resource pools from a network, selects a first resource pool among the multiple resource pools, and stores a media access control (MAC) protocol data unit (PDU) in the HARQ buffer for transmission via the first resource pool. When the UE reselects a second resource pool among the multiple resource pools, the UE flushes the HARQ buffer.

A communication device, processing device or method constructs M RLC PDUs including M RLC SDUs, respectively, where M is larger than 1; submits, for a transmission opportunity, only L RLC PDUs for L RLC SDUs with lowest L SNs among the M RLC PDUs to a MAC layer, where L<M and the L RLC PDUs include a first RLC PDU having a poll to trigger status reporting at a receiving device; transmits the L RLC PDUs to the receiving device; constructs a second RLC PDU including a second RLC SDU having a highest SN among SNs of RLC SDUs submitted to the MAC layer, when the poll retransmission timer started upon submitting the first RLC PDU having the poll expires and no new RLC SDU or RLC SDU segment can be transmitted.
