Abstract: A scheduling method and apparatus for a device to device communication are disclosed. The device to device communication method comprises the steps of: transmitting first data to a second terminal through a pre-assigned first sub-frame; and receiving a response corresponding to the first data and second data from the second terminal through a pre-assigned second sub-frame. Therefore, the present invention can prevent a collision of transmitted and received data between the devices.

Abstract: A method of searching a cell in a mobile station of a communication system in which a plurality of cells are grouped into a plurality of cell groups, each cell group including at least two cells, includes: detecting a primary synchronization signal and a secondary synchronization signal from a received signal; and identifying a cell based on a combination of the primary synchronization signal and the secondary synchronization signal. The secondary synchronization signal is related to the cell group to which the mobile station belongs and the primary synchronization signal is related to the cell to which the mobile station belongs within the cell group.

Abstract: A method and an apparatus for uplink transmission in a communication system. An operation method of a terminal includes: receiving, from a base station, first SFI information indicating n flexible symbol(s); receiving, from the base station, second SFI information re-indicating m symbol(s) of the n flexible symbol(s) as uplink (UL) symbol(s); and transmitting an SRS to the base station through the m symbol(s) re-indicated as a UL symbol among the n flexible symbol(s) indicated as a flexible symbol. Therefore, performance of the communication system can be improved.

Abstract: Disclosed are a method and an apparatus for transmitting and receiving a synchronization signal in a communication system. According to an exemplary embodiment of the present disclosure, a method of transmitting a first synchronization signal, performed by a base station in the communication system, may comprise generating a base sequence; generating a modified sequence by inverting polarity of the base sequence; mapping the base sequence and the modified sequence to a first frequency region having a frequency higher than a center subcarrier and a second frequency region having a frequency lower the center subcarrier, so that the base sequence and the modified sequence are symmetric centering the center subcarrier located at a center frequency of a frequency domain of the synchronization signal; and transmitting the synchronization signal comprising the base sequence and the modified sequence to a terminal. Therefore, performance of the communication system can be improved.

Abstract: Provided is a method of transmitting channel rank information (RI) when the number of bits for transmitting the channel RI to be transmitted through a physical uplink shared channel (PUSCH) is three or more. The method includes mapping channel RI to be transmitted to a channel RI bit string of 3 bits or more, Reed-Muller coding and rate-matching the channel RI bit string using a basis sequence having a 32-bit code length, and generating modulation symbols by applying the bit sequence that has been Reed-Muller coded and rate-matched to a modulation mapper. Accordingly, the method of transmitting downlink channel RI can be employed when five or more antennas are used for downlink transmission or several carrier bands are used by carrier aggregation as specified in Third Generation Partnership Project (3GPP) long term evolution (LTE)-advanced following 3GPP LTE release 10.
