    Abstract: Embodiments of the present disclosure provide methods for transmitting an uplink signal and a downlink signal. A method for transmitting an uplink signal comprises detecting whether there is a beam failure; if there is a beam failure, determining at least one of whether there is a candidate downlink transmission beam(s) or candidate downlink transmission beam information; and transmitting a beam failure recovery request message to a base station, the beam failure recovery request message being used for informing the base station of at least one of whether there is a candidate downlink transmission beam(s) or candidate downlink transmission beam information. A method for transmitting a downlink signal comprises detecting a beam failure recovery request message, determining at least one of whether there is a candidate downlink transmission beam(s) or candidate downlink transmission beam information in the UE; and transmitting a feedback message corresponding to the beam failure recovery request message.

    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.

    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.
