The one or more parameter may be indicated by downlink control information (DCI), one or more medium access control (MAC) control elements, implicit signaling, or any combinations thereof. | 2022-04-28 |
20220131670 | METHOD FOR SETTING TRANSMISSION TIME INTERVAL FOR DEVICE-TO-DEVICE COMMUNICATION IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR - Disclosed in the present application is a method by which a first terminal transmits a side link signal to a second terminal in a wireless communication system. Particularly, the method for transmitting a side link signal comprises the steps of: transmitting, in a first number of transmission time units, a control signal, which includes resource allocation information of a data signal, and a first reference signal for the control signal; and transmitting, in a second number of transmission time units, the data signal and a second reference signal for the data signal, wherein the transmission time units have two or more symbols, the first reference signal is transmitted in fixed symbol indexes irrespective of the first number of transmission time units, and symbol indexes in which the second reference signal is transmitted are determined on the basis of the second number of transmission time units. | 2022-04-28 |
20220131671 | REFERENCE SIGNAL HAVING VARIABLE STRUCTURE - A method for transmitting a data demodulation reference signal (DMRS) in a wireless communication system and a device therefor are disclosed. To this end, a basic DMRS is transmitted via the first OFDM symbol in a data transmission region of a predetermined subframe, and an additional DMRS is transmitted in the predetermined subframe in accordance with a level determined by a transmission environment, wherein the basic DMRS is characterized by being transmitted via the first OFDM symbol in the data transmission region of the predetermined subframe regardless of a transmission link, the structure of the subframe, and the transmission environment. | 2022-04-28 |
