    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Embodiments of the present application provide a method, a UE, a base station, a device, and a computer-readable storage medium for contention-based uplink data transmission. A method for contention-based uplink data transmission comprises: receiving high layer configuration information for a contention-based physical uplink shared channel (PUSCH) transmission; monitoring first downlink control information (DCI) scrambled with a first radio network temporary identity (RNTI) in a first physical downlink control channel search space based on the high layer configuration information, and determining a contention-based PUSCH resource based on the detected first DCI; and transmitting data on the contention-based PUSCH resource. The present application improves the data transmission efficiency and reduces the UE's power consumption.

    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). The present disclosure provides a method performed by an electronic device in a first system in a wireless communication system, wherein the first system and a second system exist in the wireless communication system, and frequency domain resources used by the first system and the second system at least partially overlap with each other. The includes: obtaining information about overlapped frequency domain resources; determining the overlapped frequency domain resources, the determined overlapped frequency domain resources comprising overlapped frequency domain resources at a subcarrier level; and avoiding performing an uplink transmission and/or avoiding monitoring a downlink transmission on the determined overlapped frequency domain resources.

    Abstract: Embodiments of the present application provides an apparatus and a method for transmitting and receiving uplink data, and relates to the field of communication technologies. The method includes: performing uplink data transmission via a contention-based random access (RACH) procedure. The embodiments of the present application implement that, when transmitting uplink data in an RRC idle mode, the user equipment does not need to establish an RRC connection, and may directly transmit the uplink data via the RACH procedure, so that the power consumption of the UE may be reduced, and the waste of system resources may be reduced.

    Abstract: A method for 2-step RA (2-step random access) performed by a terminal (UE) is provided. The method comprises receiving, from a base station, first random access channel (RACH) configuration for 4-step RA (4-step random access), second RACH configuration for the 2-step RA, and physical uplink shared channel (PUSCH) configuration, the first RACH configuration including information on RA occasions for the 4-step RA; in case that an index indicating a subset of the RA occasions is included in the second RACH configuration, identifying at least one RA occasion for the 2-step RA based on the subset; identifying at least one PUSCH resource based on the PUSCH configuration and the at least one RA occasion; and transmitting, to the base station, a random access preamble in the at least one RA occasion and a PUSCH in the at least one PUSCH resource.
