    Abstract: A method and apparatus is provided for transmitting an orthogonal frequency domain multiple access (OFDMA) signal including a synchronization channel signal transmitted within a localized portion of a bandwidth of the OFDMA signal (818), the synchronization channel signal having predetermined time domain symmetry within the localized portion of the bandwidth (816). The synchronization channel signal enables an initial acquisition and cell search method with low computational load which provides OFDMA symbol timing detection and frequency error detection by differential processing of sequence elements of the synchronization channel signal (1112) and frame boundary detection and cell specific information detection (1114) in an OFDMA system supporting multiple system bandwidths, both synchronized and un-synchronized systems, a large cell index and an OFDMA symbol structure with both short and long cyclic prefix length.

    Abstract: A base station (e.g., an evolved Node B) determines whether the physical broadcast channel (PBCH), reference signals (SCH) and common reference signals (CRS) are transmitted (or awaiting transmission) on a secondary component carrier (Scell) with the cell. The determination information is transmitted to a user equipment (UE) to inform the UE that the Scell transmissions do not include PBCH/SCH/CRS. As a result, the resource elements (REs) normally used to carry system information in the PBCH/SCH/CRS can be dynamically assigned (or reassigned) to the data channel. In this manner, the physical downlink shared channel (PBSCH) bandwidth can be increased by utilizing those resource elements that are normally reserved/assigned to the PBCH/SCH/CRS.

    Abstract: A method of establishing a direct mobile communications (DMC) link between a first user equipment (UE) and a second UE, where at least one of the first UE and the second UE is communicating on a first cellular link includes requesting that at least one of the first UE and the second UE participate in an evaluation procedure to determine a potential quality of a DMC link proposed between the first UE and the second UE. The method also includes receiving a report from at least one of the first UE and the second UE indicating the potential quality of the DMC link proposed between the first UE and the second UE according to the evaluation procedure. The method further includes establishing the DMC link between the first UE and the second UE if the potential quality of the DMC link exceeds a predetermined threshold.

    Abstract: An embodiment of a system for operating a communications controller for a group of user equipments engaged in a DMC link in a wireless communications system is provided. The communications controller is configured to allocate a set of subframes in one periodic group of subframes to the group of UEs for the DMC link, signal the set of allocated subframes to the group of UEs, and transmit parameters related to a group of HARQ processes of the DMC link.
