Abstract: Enhancement of multicast-broadcast multimedia services is disclosed by providing multiple layers that may carry additional or enhanced information. The layers may be defined over a single multicast-broadcast single frequency network (MBSFN) area, or, in additional aspects, may be defined having separate MBSFN areas. When the network provides a single MBSFN area for each layer, control information for the layers may be transmitted in a scheduled multicast-broadcast control message, while when the layers are nested with separate MBSFN areas, the control information for each layer may be transmitted in a separate multicast-broadcast control message.

Abstract: Wireless communications systems and methods related to dynamic time-division duplexing (TDD) and self-contained subframe-based communications in a shared spectrum are provided. A first wireless communication device communicates a control information communication protection request over a shared spectrum. The shared spectrum is shared by a plurality of network operating entities based on priorities. The first wireless communication device is associated with a first network operating entity of the plurality of network operating entities. The first wireless communication device communicates, with a second wireless communication device associated with the first network operating entity, control information in a first link direction during a transmission opportunity (TXOP) in the shared spectrum. The first wireless communication device communicates, with the second wireless communication device, data in a second link direction during the TXOP.

Abstract: Methods and apparatus for selecting samples for secondary synchronization signal (SSS) detection are described. Several alternatives are provided for efficient cell identifier detection. In a first alternative, multiple bursts of a signal received from a cell are sampled with non-uniform spacing between sampling intervals to determine a sequence for cell identification. In a second alternative, samples of a first and a second signal received from a stronger cell are cancelled, and a sequence for detecting a weaker cell is determined by reducing effects of the samples of a third signal received from the weaker cell which do not overlap with the primary synchronization signal (PSS) or SSS of the stronger cell. In a third alternative, a sequence for detecting a weaker cell is determined by reducing effects of any sampled bursts that correspond to a high transmission power portion of a signal from a stronger cell.
