Abstract: Embodiments of the present disclosure relate to methods and apparatuses for downlink control information (DCI) transmission and receiving in a wireless communication system. A DCI configuration parameter can be first transmitted to a terminal device; and then DCI is transmitted to the terminal device, wherein the DCI configuration parameter indicates time-frequency resources for the DCI. With embodiments of the present disclosure, the UE could perform a flexible DCI monitoring according to the DCI configuration parameter and thus it may support the DCI monitoring occasion change due to numerology and scheduling unit size.

Abstract: Embodiments of the present disclosure relate to a method and apparatus of data transmission in a wireless communication system and a method and apparatus of receiving data in a wireless communication system. The method of data reception comprises transmitting a request for the RRC message to the network node based on default transmission parameters; and receiving the RRC message from the network node at a predetermined time unit. With embodiments of the present disclosure, it is possible to request the RRC message when the terminal device need this message and therefore the RRC message transmission can be reduced and in turn, the inter-node interference can be limited, and the number of LBTs required for these signal transmissions can be reduced if they are transmitted on unlicensed spectrum.
