    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. 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.

    Embodiments of the present disclosure provide a blind detection method for Physical Downlink Control Channel (PDCCH) candidate, comprising: determining a resource location of a serving cell for transmitting the PDCCH candidate corresponding to a Primary cell (Pcell), wherein, the serving cell includes Pcell and/or Secondary cell (Scell); and blindly detecting the PDCCH candidate corresponding to Pcell on the determined resource location of the serving cell. Based on the solution of the embodiment of the present application, in a CA system, the allocation of the resources occupied by the PDCCH can be implemented more reasonably and effectively.

    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). A technique for receiving a downlink control channel is provided that includes operations of determining whether a physical downlink shared channel (PDSCH) is received at a time-domain position n; determining, according to a result of the determining, a frequency-domain position of a bandwidth part (BWP) for receiving a physical downlink control channel (PDCCH) at a time-domain position n+1, and receiving the PDCCH at the BWP of the frequency-domain position. The technique determines the frequency-domain position of the BWP for receiving the PDCCH by determining whether it is necessary to receive the PDSCH at the time-domain position preceding the current time-domain position for receiving the PDCCH, greatly reducing or even eliminating the influence of the adjustment time interval for the user equipment (UE) to convert the BWP on the normal data reception of the UE, which ensures the receiving performance and the throughput level of the received data of the UE.
