    Abstract: A method and device for reporting scheduling request are provided. The method includes the operations of acquiring a dedicated physical resource of a random access channel (RACH) configured to report a scheduling request, when the scheduling request is triggered, transmitting the RACH on the dedicated physical resource. The dedicated physical resource includes a plurality of periodic physical resources. Through this dedicated physical resource, the user equipment (UE) can report scheduling request in a contention-free random access way, and the capacity of a preamble sequence is improved and inter-cell interference is reduced.

    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 application provides a data receiving method. The method includes: when a category-1 service occupies resources scheduled for a category-2 service, a terminal receives data of the category-2 service according to information about scheduling of category-1 service data. According to the present application, resources of category-2 services can be reused for receiving category-1 service data to satisfy requirements for low delay of the category-1 services and increase the utility efficiency of resources of the category-2 services.

    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 discloses a method for detecting signals of a downlink control channel, including: determining, by a user equipment, an initial control resource set, and receiving common control information from resources specified in the initial control resource set before establishing a radio resource control (RRC) connection; after establishing the RRC connection, determining, by the user equipment, a first control resource set where a user-specific search space is located, and determining the user-specific search space from the first control resource set according to information sent by a base station and/or a user bandwidth capacity and/or a user service type; and detecting, by the user equipment, user control information in the user-specific search space determined. When the present disclosure is implemented, a lower transmission delay and higher transmission reliability can be achieved for a control channel.

    Abstract: The present invention discloses a method for receiving scheduling information, comprising steps of: receiving Downlink Control Information (DCI); and determining, according to a mapping relationship between configured transmission resources used for a Physical Uplink Shared Channel (PUSCH) and scheduling information in the DCI, scheduling information corresponding to the PUSCH in the DCI. Compared with the prior art, in the present invention, the scheduling information in the DCI is determined by the mapping relationship between the configured transmission resources used for transmitting the PUSCH by a UE and the scheduling information in the DCI, so that a base station can schedule all UEs for which there is a mapping relationship between PUSCH configured transmission resources and the scheduling information in DCI by sending only one piece of DCI. The scheduling overhead is reduced, the resource waste is reduced, and the efficiency of scheduling terminals by a communication system is significantly improved.
