Abstract:
The disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates than 4G communication systems such as LTE systems. A method performed by a receiving apparatus in a wireless communication system is provided. The method includes receiving reference signals from a transmitting apparatus, estimating respective channel component values of the reference signals, determining whether at least one reference channel component value which is equal to or greater than a first threshold is present among the channel component values of the reference signals, selecting a candidate beam based on the at least one reference channel component value in case that the at least one reference channel component value is present, determining whether a value of signal quality of the first candidate beam is equal to or greater than a second threshold, and selecting the candidate beam as a final beam in case that the value of signal quality of the candidate beam is equal to or greater than the second threshold.
Abstract:
The present disclosure is related 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. A method for operating a base station includes transmitting, to a terminal, configuration information for measuring a channel blockage status indicating a degree by which an unlicensed band is occupied by an interference node, receiving information regarding the channel blockage status measured based on the configuration information, transmitting, to the terminal, scheduling information regarding uplink resources generated based on the information regarding the channel blockage status, and receiving data from the terminal based on the scheduling information, wherein the configuration information comprises at least one of information regarding a measurement duration for measuring the channel blockage status, information regarding uplink resources allocated to measure the channel blockage status, and information regarding a channel occupancy time of the base station.
Abstract:
This disclosure relates to the 5th generation (5G) or pre-5G communication system for supporting a higher data rate after the 4th generation (4G) communication system such as Long Term Evolution (LTE). The method for operating the core network in a wireless communication system according to this disclosure comprises the processes of determining the content to store in the terminal based on the location information of the terminal, transmitting the content transmission command to the base station so as to transmit the content to the terminal in response to the determination, checking whether the terminal has entered the overload cell, and forming a D2D communication link between the terminal and another adjacent terminal when it is identified that the terminal has entered the overload cell.
Abstract:
The disclosure relates to a fifth-generation (5G) or a pre-5G communication system for supporting a higher data transfer rate than a fourth-generation (4G) communication system such as Long-Term Evolution (LTE). The disclosure relates to uplink transmission in a wireless communication system, in which an operating method of a user equipment (UE) may include: receiving information about a UE group to which the same uplink resource is allocated from a base station; receiving uplink resource allocation information corresponding to the UE group from the base station; performing channel access for uplink transmission on the basis of the received uplink resource allocation information; and transmitting uplink data to the base station after accessing a channel, wherein the channel access may be performed using a multilevel threshold value in a contention slot for the UE.
Abstract:
A scheduling method and an apparatus are provided for use in a Device-to-Device (D2D) communication system. A scheduling method of a node in a wireless communication system according to the present disclosure includes acquiring a first data rate on a first link in consideration of interference occurring when a second link is established, acquiring a second data rate on the first link without consideration of the second link, acquiring, when the second link is established, a third data rate on the second link, and determining whether to establish the second link in consideration of the first data rate, second data rate, and third data rate.
