摘要： Methods for performing communication by a user equipment (UE) and a base station (BS) in a wireless communication system, a UE, and a BS are provided. The method for performing communication by the UE includes identifying a starting orthogonal frequency division multiplexing (OFDM) symbol for a downlink (DL) channel in a subframe based on higher layer signaling; identifying a bandwidth of the DL channel based on a modulo operation using a cell identity and a predetermined number; and receiving the DL channel in the subframe based on the starting OFDM symbol and the bandwidth.

摘要： Methods and apparatuses are provided for wireless communication. Control symbols are mapped to a plurality of resource element groups (REGs) which is not assigned to a physical channel format indication channel (PCFICH) or a physical hybrid automatic repeat request indicator channel (PHICH).

摘要： Disclosed are a method and an apparatus for operating multi-band and multi-cell. An Enhanced Node B (eNB) transmits a synchronization channel and a broadcasting channel for narrow-band user equipments (UEs) through a first band narrower than a system band, the first band being located in a center band of the system band, and transmits a control channel for scheduling a data channel for a first narrow-band UE which is one of the narrow-band UEs through a second band equal to or wider than the first band, the second band not overlapping the first band within the system band. The first band is designed to be matched to a band where the synchronization channel and the broadcasting channel of a host cell using an entire system band are transmitted.

摘要： Methods and apparatus are provided for the transmission of physical downlink control signaling. In one method, a User Equipment (UE) receives information associated with a physical resource block (PRB) for enhanced physical downlink control channel (EPDCCH) from a base station. Based on either first information received on physical control format indicator channel (PCFICH) or second information received on higher layer signaling, the UE determines a starting orthogonal frequency division multiple (OFDM) symbol on which EPDCCH transmission starts. The UE receives control information on the EPDDCH based on the information associated with the PRB and the determined starting OFDM symbol.

摘要： Methods and apparatuses for a User Equipment (UE) to receive signaling of UE-common Downlink Control Information (DCI) in a set of Physical Resource Blocks (PRBs) over a Transmission Time Interval (TTI) are provided. The UE demodulates UE-common DCI using a Reference Signal (RS) that is scrambled by a UE-common scrambling sequence. The UE may assume that RS having a same precoding is transmitted in the set of PRBs over different TTIs. The UE may determine the scrambling sequence implicitly from an identity of a point transmitting the UE-common DCI or explicitly by higher layer signaling. The UE may determine the PRBs of UE-common DCI transmission by broadcast signaling or by higher layer signaling.
