A Quality of Experience (QoE) optimization system and method are provided. An electronic device inputs key performance indicators (KPIs) and system control parameters collected from a core network, a base station and a user equipment (UE) into a QoE optimization model. The QoE optimization model then optimizes the system control parameters based on the KPIs and a user QoE fed back from the UE to output optimized system control parameters. Furthermore, a strategy emulator controls at least one of a base station emulator and a UE emulator, so as to emulate the QoE optimization model using the at least one of the base station emulator and the UE emulator. Non-real-time optimization adjustments to the QoE optimization model are made based on the result of the emulation performed by the at least one of the base station emulator and the UE emulator.

A communication device includes a communication unit that performs radio communication; and a control unit that performs control so as to switch an HARQ feedback mode in a communication scheme of inter-device communicating with another device through the radio unit between a first mode in which NACK-based feedback is performed and a second mode in which ACK/NACK-based feedback is performed, in which the control unit controls switching of an HARQ feedback mode based on information about an identifier of a group including the communication device and about the number of devices in the group.

Adjusting communication channels used by camera to communicate with a base station are described. In one aspect, characteristics of communication channels can be determined and the operation of the camera can be adjusted to use a communication channel based on a comparison of the characteristics of multiple communication channels.

A method of performing adaptive mode switching in a transmitter of a dual mode simultaneous wireless information and power transmission (SWIPT) system, incudes receiving received power of a receiver in a channel; comparing the received power with a predetermined threshold value; selecting one of a single tone mode or a multi-tone mode as a single/multi-tone mode based on the comparison result; selecting a modulation index based on the selected single/multi-tone mode and the received power; and transmitting the selected single/multi-tone mode, the selected modulation index, and a duty cycle to the receiver. The duty cycle is determined based on at least one of power consumed for decoding a single tone signal, power consumed for decoding a multi-tone signal, and power harvested during the channel by the receiver.

The present disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides an apparatus and method for efficiently transmitting a packet in a wireless communication system. The present disclosure relates to an operation method for a transmitter in a wireless communication system, the operation method comprising the steps of: mapping a parameter according to quality of service (QoS) information or a service type; determining, on the basis of the parameter, whether to duplicate a packet; when it is determined that the packet is to be duplicated, duplicating the packet; and transmitting the duplicated packets to a receiver.

Methods and apparatus are provided for managing code block interleaving and de-interleaving in wireless communication systems. A transmitter detects one or more conditions related to transmissions to be made from the transmitter and decides, based on the detection, to disable an interleaver while processing the transmissions, the interleaver used to spread code blocks over available resources. A receiver detects one or more conditions relating to the transmissions from the transmitter and determines, based on the detection, whether an interleaver was used at the transmitter while processing the transmissions. The receiver decides whether or not to de-interleave code blocks of the received transmission based on the determination.

The disclosure is related to adaptive encoding of video streams from a camera. A camera system includes a camera and a base station connected to each other in a first communication network, which can be a wireless network. When a user requests to view a video from the camera, the base station obtains an encoded video stream from the camera and transmits the encoded video stream to a user device. The base station monitors multiple environmental parameters, such as network parameters, camera parameters, and system parameters of the base station, and instructs the camera to adjust the encoding of the video stream, in an event one or more environmental parameters change.

Embodiments of the present disclosure relate to methods, apparatuses and computer readable storage media for channel state information (CSI) reporting. According to embodiments of the present disclosure, a first device receives from a second device a configuration for CSI reporting. The configuration comprises at least a block error rate target and an indication of a number of HARQ transmissions. The first device determines Channel Quality Indicator (CQI) based on the block error rate target and the number of HARQ transmissions indicated by the configuration and transmits a CSI report comprising the CQI to the second device. The solution enables CSI feedback that is suitable for spectrally efficient and reliable delivery of Point to Multipoint services while meeting the delay requirement, in particular in the context of NACK-only feedback on common feedback resources.
