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). Next generation of wireless cellular operation is expected to be deployed in higher frequency above 6 GHz (eg. 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.

Abstract: A method is provided for when an allocation area of data indicated by control information overlaps a subsequent control information area occurring after a control information area is pre-configured by a higher layer signal or system information. 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.

Abstract: Methods and apparatuses are provided for transmitting uplink control information by a terminal in a wireless communication system. System information associated with an uplink transmission of a reference signal is received from a base station. Uplink control information to which a length-3 orthogonal sequence or a length-4 orthogonal sequence is applied is transmitted in a slot of a sub-frame. The reference signal is transmitted based on the received system information.

Abstract: A method and an apparatus method are provided for transmitting uplink information including acknowledgement information in a wireless communication system. The method includes determining whether transmission of acknowledgement information overlaps with transmission of uplink data in a time domain; multiplexing the uplink data and the acknowledgement information, in case that the transmission of the acknowledgement information overlaps with the transmission of the uplink data in the time domain; and transmitting the multiplexed uplink data and acknowledgement information to a base station. The acknowledgement information is located adjacent to a pilot for the uplink data, and the pilot is used for demodulation of the uplink data.

Abstract: Methods and apparatuses are provided for establishing time alignment by a terminal in a wireless communication system. Information for identifying a preamble is received from the base station on the downlink control channel. The preamble is transmitted to the base station based on the information for identifying the preamble. A message including information for a channel quality indicator (CQI) request is received from the base station. A CQI is transmitted to the base station based on the information for the CQI request response message. A CQI is transmitted to the base station based on the information for the CQI request.

Abstract: A method and an apparatus method are provided for transmitting uplink information including acknowledgement information in a wireless communication system. The method includes coding, by a terminal, uplink data and the acknowledgement information by using different coding schemes respectively; multiplexing, by the terminal, the coded uplink data and the coded acknowledgement information into the uplink information; and transmitting, by the terminal, the uplink information using resources. At least a portion of the uplink data is transmitted based on a first resource and the acknowledgement information is transmitted based on a second resource. The first resource and the second resource are adjacent to each other with respect to a time domain and a frequency domain. The acknowledgement information is located immediately adjacent to a pilot for the uplink data, and the pilot is used for demodulation of the uplink data.
