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). Next generation of wireless cellular operation is expected to be deployed in higher frequency above 6 GHz (e.g., 10 GHz˜100 GHz, also called mmWave and/or cmWave) due to availability of large amount of spectrum bandwidths. The physical layer of wireless cellular system in both DL and UL operating in mmWave/cmWave would be based on new air-interface different from that of LTE-A air-interface because the radio characteristics is different for mmWave/cmWave bands. The wireless system deployed in mmWave/cmWave system is expected to employ DL beam sweeping on broadcast control information to provide cell coverage to the UE which would result in excessive signaling overhead.

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). Next generation of wireless cellular operation is expected to be deployed in higher frequency above 6 GHz (eg. 10 GHz&#x2dc;100 GHz, also called mmWave and/or cmWave) due to availability of large amount of spectrum bandwidths. The physical layer of wireless cellular system in both DL and UL operating in mmWave/cmWave would be based on new air-interface different from that of LTE-A air-interface because the radio characteristics is different for mmWave/cmWave bands. The wireless system deployed in mmWave/cmWave system is expected to employ DL beam sweeping on broadcast control information to provide cell coverage to the UE which would result in excessive signaling overhead.

The present disclosure relates to a method of providing a pre-5-Generation (5G) or 5G communication system for supporting higher data rates Beyond 4-Generation (4G) communication system, such as Long Term Evolution (LTE). The method includes receiving configuration information comprising at least one information element indicating transmission resources for the reference signals, receiving downlink control information indicating that a transmission of at least one of the reference signals is activated, and receiving the at least one of the reference signals based on the configuration information, in response to receiving the downlink control information.

Method and apparatus for transmitting and receiving reference signal

Methods and apparatus are provided in which data is received from a base station on a downlink data channel. It is determined whether a scheduling type of the downlink data channel is persistent or non-persistent. In case that the scheduling type is non-persistent, ACK/NACK information for the data is transmitted to the base station on a resource which is determined based on a first ACK/NACK resource allocation scheme. In case that the scheduling type is persistent and the data is initial persistent data, ACK/NACK information for the data is transmitted to the base station on a resource which is determined based on the first ACK/NACK resource allocation scheme. In case that the scheduling type is persistent and the data is persistent data following the initial persistent data, ACK/NACK information for the data is transmitted to the base station on a resource determined based on a second ACK/NACK resource allocation scheme.

Method and apparatus for allocating and signaling ack/nack resources in a wireless communication system

A method and apparatus are provided for transmitting and receiving control information. A method in a base station includes transmitting, to a terminal, information associated with a resource region carrying a control channel; transmitting, to the terminal, a plurality of values associated with control channel candidates, each of the plurality of values corresponding to each of a plurality of numbers associated with CCEs constituting one control channel candidate, wherein the each of the plurality of values indicates a number of control channel candidates to be monitored by the terminal; determining a set of control channel candidates based on an ID of the terminal and at least one of the plurality of values associated with the control channel candidates; selecting at least one control channel candidate from among the set of control channel candidates; and transmitting the control information to the terminal through the at least one selected control channel candidate in the resource region.

A terminal may omit or partially perform a blind search for the subsequent control information area overlapping a data area. Additionally, a terminal may receive data based on an assumption that a data area has been mapped to the subsequent control information area, or a terminal may receive data based on an assumption that a data area has not been mapped to the subsequent control information area. Thus, the terminal may adaptively adjust a configuration area for a data area and prevent blind decoding to further reduce power consumption.
