    Abstract: A method and a corresponding apparatus for performing uplink transmission in a wireless communication system are disclosed. The method comprises: based on at least one of the information indicating uplink transmission resources, acquiring the number of resource elements REs used for determining a PUSCH transmission; determining a transport block size TBS for the uplink transmission based on the number of REs; and performing the uplink transmission based on the determined TBS. Wherein, a PUSCH transmission occupies m time unit for transmission, and the rate matching and RE mapping of the PUSCH are performed on all resources occupied in m time unit.

    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 for operating a user equipment (UE) in wireless communication system. The method includes: receiving, from a base station, configuration information for a two-step random access transmission; determining a resource configuration for transmitting a first message of the two-step random access transmission based on the obtained configuration information for the two-step random access transmission, wherein the first message comprises a preamble and data; transmitting, to the base station, the first message according to the determined resource configuration; detecting a second message from the base station as a feedback of the first message; and performing a subsequent operation according to the detected second message.

    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. The present disclosure provides a method for uplink power control, which is applied to a User Equipment (UE), and the method includes: determining a timing between a power control command and a Physical Uplink Control Channel (PUCCH), which adopts the power control command to control power. The present disclosure also provides a corresponding device.

    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 resource scheduling method, which includes: determining, by a UE, a resource allocation indicating way in DCI of a first type search space and a resource allocation indicating way in DCI of a second type search space, performing, by the UE, blind detection for PDCCH/EPDCCH on the bandwidth and the location of all the frequency resources available for the UE frequency resource allocation in the corresponding resource allocation indicating way according to the allocation unit of the UE frequency resource in the corresponding resource allocation indicating way, determining a bandwidth and a location of an uplink resource and/or a downlink resource actually allocated for the UE.
