A method by a terminal in a communication system and an apparatus therefor are disclosed. The method includes receiving, from a base station, a radio resource control (RRC) message including a radio link control (RLC) configuration and a packet data convergence protocol (PDCP) configuration associated with a packet duplication, identifying whether a PDCP packet data unit (PDU) is a PDCP control PDU in case that the packet duplication is activated, and transmitting, to the base station, the PDCP control PDU without the packet duplication through a primary RLC entity based on the PDCP configuration in case the PDCP PDU is the PDCP control PDU. The disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates with a technology for internet of things (IoT), and may be applied to intelligent services based on the 5G communication technology and the IoT-related technology.

A split radio access architecture comprises a packet processing node and one or more baseband processing nodes. The packet processing node receives, from a baseband processing node, first feedback corresponding to air interface congestion between the baseband processing node and a wireless device receiving packets from the baseband processing node. The packet processing node also receives, from the baseband processing node, second feedback corresponding to transport network congestion of a transport interface between the packet processing node and the baseband processing node. The packet processing node transmits user data to the baseband processing node based on the received first and second feedback.

Manners of scheduling downloads for a user equipment (UE). The UE is configured to establish a connection to a network and receive an indication of a user-initiated download, determining whether the download is to be performed now or at a subsequent time, when the download is to be performed at the subsequent time, determine a time window during which the download is to be initiated and initiate the download during the time window.

In one example, an Access Point (AP) configures a first mapping of a first cellular network connection to a first local access network group, and further configures a second mapping of a second cellular network connection to a second local access network group. The AP determines whether a user device is authorized to use the first cellular network connection or the second cellular network connection. If the user device is authorized to use the first cellular network connection, the AP associates, for the user device, a first user device identifier with the first local access network group. If the user device is authorized to use the second cellular network connection, the AP associates, for the user device, a second user device identifier with the second local access network group.

The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method for processing a packet by a transmission device in a wireless communication system according to an embodiment of the present invention comprises the steps of: checking whether a data radio bearer (DRB) mapped to a quality of service (QoS) flow changes from a first DRB to a second DRB; and when the DRB changes from the first DRB to the second DRB, transmitting, to a reception device, information on a last packet transmitted through the first DRB in the QoS flow.

A communication method and apparatus. The method may be applied to a 4G system, a 5G system, and/or a future communication system such as a 6G system. The method includes: a splitting protocol layer entity of a terminal device configures a first sequence number SN of a splitting protocol layer in a first splitting protocol layer data packet, and configures a second SN of the splitting protocol layer in a second splitting protocol layer data packet. The splitting protocol layer entity of the terminal device sends the first splitting protocol layer data packet to a first protocol layer entity corresponding to a first access network device, and sends the second splitting protocol layer data packet to a first protocol layer entity corresponding to a second access network device.

Techniques that provide low latency traffic segregation to ensure an edge user plane (UP) is not overloaded are described herein in at least one embodiment. In at least one embodiment, a method may include determining offload of low latency traffic of a user equipment (UE) at a mobile network edge, wherein the UE has non-low latency traffic associated with a first packet data network session for an access point name; notifying the UE to request creation of a second packet data network session for the access point name; selecting an edge UP element to handle the low latency traffic for the second packet data network session; creating the second packet data network session at the selected edge UP element; and notifying the UE that second packet data network session is created.

A client device in a wireless network accesses a queue comprising Transmission Control Protocol Acknowledgement (TCP ACK) packets, at least some of which include packet descriptors, each with a flow identifier indicating a TCP flow associated with the packet, and a TCP ACK Generation Count. The device inspects a packet descriptor of a first TCP ACK packet, and identifies a first flow identifier and a first TCP ACK Generation Count. The device accesses entries in a data structure that each includes a first field and a second field respectively storing a flow identifier and a TCP ACK Generation Count. The device determines that a first entry in the data structure includes a flow identifier and a TCP ACK Generation Count matching the first flow identifier and the first TCP ACK Generation Count, respectively. In response to the determination, the device marks the first TCP ACK packet to be dropped.

Aspects described herein relate to determining a congestion level related to communicating with one or more devices in a wireless network, determining, based on the congestion level, a retransmission scheme for transmitting and/or retransmitting communications in the wireless network, and transmitting or retransmitting a communication in the wireless network based on the retransmission scheme.

A relay device first receives a data packet from a network device through a first link, and sends the data packet to user equipment through a second link. A protocol stack of the relay device consists of a physical layer, a media access control layer, and a segmentation function or a resegmentation function of a radio link control layer; a protocol stack of the relay device consists of a physical layer, a media access control layer, a segmentation function or a resegmentation function of a radio link control layer, and an adaptation layer; or a protocol stack of the relay device consists of a physical layer and a hybrid automatic repeat request function of a media access control layer. The first link is a wireless communication link between the network device and the relay device, and the second link is a wireless direct communication link between the relay device and the user equipment.
