    摘要: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate beyond a 4G communication system such as LTE. To this end, a base station using a large-scale antenna transmits, to a terminal, reference signal resource configuration information including multiple pieces of reference signal configuration information and reference signal port information, for transmission of a reference signal, and transmits the reference signal to the terminal using some or all of channel measurement resources indicated by the multiple pieces of reference signal configuration information and the reference signal port information included in the reference signal resource configuration information. In this case, the channel measurement resources may correspond to antenna ports, the number of which is indicated by a combination of the multiple pieces of reference signal configuration information and the reference signal port information.

    摘要: A method and system for transmitting and receiving a control channel in a dynamic Time Division Duplex (TDD) system. Upon receiving a control signal DCI for a first Hybrid Automatic Retransmission Request (HARQ) process from a Node B, a User Equipment (UE) determines whether TDD configuration is changed in a radio frame to which the DCI is to be applied. If the TDD configuration is changed, the UE determines from the DCI whether retransmission for the first HARQ process is required. If the retransmission required, the UE interprets some bits of a Modulation and Coding Scheme (MCS) field in the DCI as a target HARQ process index for the first HARQ process. As a result, the most is made of available UL data channel resources, contributing to an increase in the capacity of the dynamic TDD system and a reduction in packet delays of the UE.

    摘要: A method and apparatus for transmitting Time Division Duplexing (TDD) configuration information by an evolved Node B (eNB) in a TDD wireless communication system are provided. The method includes determining a changed TDD configuration indicating a transmission direction of a plurality of sub-frames constituting a frame; generating a system information element including dynamic TDD configuration information indicating the changed TDD configuration; transmitting a system information block including the dynamic TDD configuration information; and sending a Media Access Control (MAC) message including information indicating whether a change in TDD configuration is activated.

    摘要: A base station is provided. The base station transmits multiple data in a first subframe, receives response signals corresponding to the multiple data, determines a ratio of negative acknowledge (NACK) signals to the response signals, and adjusts or maintains a contention window based on the determined ratio. The present disclosure relates to communication schemes for combining 5th-generation (5G) communication systems with internet of things (IoT) technology to support higher data transmission rate as post-4th-generation (post-4G) systems and systems for the same. The present disclosure may be used in intelligent services (e.g., smart home, smart building, smart city, smart car, or connected car, health-care, digital education, retail business, security and safety-related services, etc.) based on the 5G communication technology and IoT-related techniques.

    摘要: Disclosed in one embodiment is a downlink control channel decoding method of a wireless communication system, comprising the steps of: receiving setting information on a first resource and a second resource; blind-decoding reception signals on PDCCH resource candidates within the first resource determined by the setting information, so as to search for a PDCCH of the first resource; and blind-decoding reception signals on PDCCH resource candidates within the second resource determined by the setting information, and by blind-decoding, among the resource candidates, the remaining one or more resource candidates excluding one or more resource candidates, which include a resource area overlapping with the PDCCH having been searched for, so as to search for a PDCCH of the second resource. Therefore, since the number of PDCCH resource candidates required for blind-decoding is adjusted on the basis of an overlapping resource area, power consumption of a terminal can be reduced.
