Abstract: A wireless communication system includes a first transmitter and a second transmitter. For a transmission or reception of data of a first user equipment and data of a second user equipment on resources shared by the first user equipment and the second user equipment, the first transmitter is configured for a superimposed non-orthogonal multiple access, NOMA, transmission or reception of a first data signal of the first user equipment and a second data signal of the second user equipment, and the second transmitter is configured for a superimposed non-orthogonal multiple access, NOMA, transmission or reception of a third data signal of the first user equipment and a fourth data signal of the second user equipment.

Abstract: An operation method of a first cell in a communication system may include: receiving, from a first communication node that is an upper node of the first cell, a first signal including second cell configuration information of a second cell connected with the first communication node and a second communication node that is a lower node of the first cell; identifying, based on the first signal, that the first cell and the second cell are jointly operated by the first communication node as coordinative PCells; transmitting, to the second communication node, a second signal including information on joint operations of the coordinative PCells by the first communication node; and performing communication with the first communication node and the second communication node based on the joint operations of the coordinative PCells.

Abstract: A timing adjustment method performed by a terminal may include: acquiring downlink synchronization with a base station; obtaining, from the base station, TA granularity-related information; transmitting, to the base station, a preamble and/or an SRS; receiving, from the base station, a TA command generated based on the preamble and/or SRS; determining a timing for uplink frame transmission by interpreting the TA command based on a TA granularity determined based on the TA granularity-related information; and performing the uplink frame transmission based on the determined timing.

Abstract: Disclosed is a wireless communication system using multiple transmission and reception points. In a wireless communication system having a first transmission and reception point and at least one second transmission and reception point belonging to the same cell, the first transmission and reception point has a wider transmission area than the at least one second transmission and reception point, and the first transmission and reception point and the at least one second transmission and reception point generate downlink transmission signals by using the same physical layer cell ID or virtual cell IDs allocated to each terminal, and then the terminals generate uplink transmission signals by using the allocated virtual cell IDs.

Abstract: An operation method of a first communication node may include: mapping data symbols to be transmitted to a second communication node of the communication system to resources in a first two-dimensional (2D) domain; pre-processing the data symbols mapped to the resources in the first 2D domain to spread the data symbols on resources in a second 2D domain; mapping the pre-processed data symbols to the resources in the second 2D domain; and performing multi-carrier modulation on the data symbols mapped to the resources in the second 2D domain for each of the resources in the second 2D domain.

Abstract: The present invention relates to a method for transmitting uplink control information in a mobile communication system; and, more particularly, to a method for effectively forming uplink control information transmitted through a downlink from a base station to a terminal in a mobile communication system for providing a packet service and transmitting the uplink control information with minimum radio resources occupied. The method includes the steps of generating uplink control information; allocating the uplink control information to a downlink-shared radio resource for packet data transmission based on downlink scheduling information; and transmitting the radio resource to a terminal. The present invention is applied to a mobile communication system.
