Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method for preventing a loss of data packets of a transmission end is provided. The method includes performing a path switching operation, receiving, from a reception end, a switching status report that includes information related to the data packets that were not received by the reception end, and retransmitting the data packets that were not received by the reception end, where the path switching operation is an operation of switching a data transmission path from a first communication system to a second communication system or from the second communication system to the first communication system, and where the first communication system is a fourth generation (4G) communication system, and the second communication system is a fifth generation (5G) communication system that uses a millimeter-wave (mm-wave) band.

Abstract: The present disclosure relates to a fifth-generation (5G) or pre-5G communication system to support a higher data transmission rate, following a fourth-generation (4G) communication system including long term evolution (LTE). A method for operating an electronic device is provided. The method includes determining the properties of a first signal and a second signal that are transmitted through different frequency bands and performing line-of-sight (LoS) determination based on the determined properties of the first signal and the second signal.

Abstract: The present disclosure relates to a fifth generation (5G) or pre-5G communication system to be provided to support a higher data transmission rate since fourth generation (4G) communication systems like long-term evolution (LTE). A method of a receiver in a wireless communication system is provide. The method includes receiving at least one packet, identifying whether there is a non-received packet among the at least one packet, and transmitting status report information when there is the non-received packet, in which the status report information includes a field indicating whether there are consecutively non-received packets.
