    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 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 grant-free data transmission method. The method includes: receiving resource allocation information for grant-free transmission from a base station; when there is data to be transmitted in a grant-free transmission mode, transmitting uplink data using the grant-free transmission resources according to the resource allocation information; if the transmission of the uplink data cannot be completed within a predefined number of uplink data transmissions, transmitting a dedicated resource request indicator to the base station; receiving dedicated resource allocation information from the base station; and transmitting subsequent uplink data on dedicated resources corresponding to the dedicated resource allocation information. The present disclosure further provides a grant-free data transmission method applied to the base station, a UE and a base station. The technical solution of the present disclosure can improve the data transmission reliability as well as system spectrum utilization ratio.

    Abstract: The present disclosure discloses a method for performing a hybrid automatic repeat request (HARQ) feedback, method comprises: receiving data units; performing group bundling on the data units, wherein at least one data unit is bundled into more than one groups; determining, according to decoding results of the data units in each of the groups, ACK/NACK information of corresponding groups; feeding back ACK/NACK information of different bundled groups to the transmitter. Compared with the prior art, according to the present disclosure, a receiver performs grouping on data units in a way of overlapping bundling, group is used as a unit for feedback of ACK/NACK information, thus feedback overhead of HARQ feedback is reduced, data amount of HARQ-transmitter error retransmission is significantly reduced and efficiency of error retransmission is improved. In addition, the present disclosure further provides an HARQ retransmission method.
