    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 relates to the retransmission in wireless communication system. A method of operating a base station comprises transmitting resource configuration information related to a resource for an initial transmission and a resource for a retransmission to a terminal, receiving initially-transmitted data through a first resource, and receiving retransmitted data through a second resource, if a decoding of the initially-transmitted data fails. The second resource is determined based on the first resource and the resource configuration information.

    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). Method and apparatus for interleaving is provided. The method includes the following steps: constructing a plurality of pseudorandom sequences according to a pre-defined length of an interleaving sequence to be constructed; for each of the constructed pseudorandom sequences, constructing at least one corresponding numerical digit random sequence according to a number of more than two types of numerical values in this pseudorandom sequence; and, for each of the constructed pseudorandom sequences and the at least one corresponding numerical digit random sequence thereof, constructing a corresponding interleaving sequence according to a mapping relation between this pseudorandom sequence and the numerical digit random sequence, so that a plurality of interleaving sequences are allocated and indicated as multiple access signatures.

    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, wherein the resource allocation indicating way comprises an allocation unit of a UE frequency resource and a bandwidth and a location of all frequency resources available for UE frequency resource allocation; in the first type search space and the 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. According to the present disclosure, in a condition that the UE cannot support the entire system bandwidth, an uplink resource and a downlink resource allocated by a base station can still be appropriately determined.
