Providing for secondary synchronization encoding utilizing a primary synchronization channel (P-SCH)-related scrambling code is described herein. Scrambled secondary synchronization codes (SSCs) can be assigned to multiple base stations of a radio access network (RAN). By way of example, PSC-based scrambling codes can be created from a plurality of M-sequences generated from a common polynomial expression. Further, an SSC codebook is provided that selects sequence pairs of a sequence matrix for generating SSCs. Selection can be based on transmission characteristics of resulting SSCs, providing reduced interference in planned, semi-planned and/or unplanned mobile deployments.

A method, an apparatus, and a computer program product for wireless communication are provided in which a system timing is estimated, derived from timing of one or more cells, a timing offset is determined for a plurality of cells relative to the estimated system timing, and signals received form the plurality of cells are processed using the timing offsets. In addition, a method, an apparatus, and a computer program product for wireless communication are provided in which a carrier frequency is estimated, derived from a frequency of one or more cells, a frequency offset is determined for a plurality of cells relative to the estimated system timing, and signals received form the plurality of cells are processed using the frequency offsets.

Per-cell timing and/or frequency acquisition and their use on channel estimation in wireless networks

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.

A refractory wall comprises a hotface layer comprising a hotface surface configured to be adjacent to a carbonaceous gasification environment, a backing layer facing the hotface layer, and a cooling layer facing the backing layer and configured to cool the hotface layer via the backing layer. A gasification device and a gasification process are also presented.

Refractory walls, and gasification devices and methods

An idle mode UE can RACH to a cell different from the cell paging the UE. The UE can be allocated additional time to respond to all cells in the neighborhood to identify the cell in which to RACH. Interference cancellation can occur at different rates based on whether the UE is in connected mode or idle mode. The time to respond to the page can be a function of a paging cycle. Additionally, a variable bias may promote early handoff to lower power cells and late handoff to high power cells.

Idle mode operation in heterogeneous networks

Methods and apparatuses are provided that include selecting reference signal (RS) or other tones to utilize in estimating a channel for decoding one or more channels. Where the RS tones are interfered by other base stations, interference cancelation can be performed over the RS tones. Since interference can vary over the tones, interference cancelation can yield RS tones of varying quality. Thus, a quality of each of the RS tones can be determined, and at least a subset of the RS tones can be selected for estimating a channel. Additionally or alternatively, the RS tones can be weighted or otherwise classified for performing channel estimation using the RS tones.

An injector for co-feeding liquid and solid fuels into a gasifier is provided. The injector includes a body, a first member, and a second member. The body comprises a first channel for conveying a liquid fuel. The first member surrounds the body to define a second channel for pneumatically conveying a solid fuel. The second member surrounds the first member to define a third channel for conveying a fluid stream for dispersing the solid fuel. The liquid fuel is atomized before being mixed with the solid fuel. A method for co-feeding liquid and solid fuels is also presented.

A system for gasification of a solid powder is provided. The system comprises one or more conveying tanks configured to receive a solid powder and one or more solid pumps disposed downstream of and in fluid communication with the one or more respective conveying tanks. The system further comprises a gasifier disposed downstream of and in fluid communication with the one or more solid pumps. A conveyance unit and a method for conveyance and gasification of a solid powder are also presented.

Certain aspects of the present disclosure relate to methods and apparatus for blind detection of cell-specific reference signals. Methods and apparatus are provided for detecting a cell-specific reference signal (CRS) in an orthogonal frequency division multiplexed (OFDM) symbol by a user equipment (UE). The method generally includes predicting a current channel response of a current OFDM symbol based on a channel response of at least one previous OFDM symbol, estimating a noise power level of the current OFDM symbol, forming a log likelihood ratio (LLR) of two detection hypotheses based on the predicted current channel response and the estimated noise power level, comparing the LLR to a pre-determined threshold, and determining that at least one CRS is present in the current OFDM symbol based on the comparison.

Blind CRS detection

Methods and apparatus for providing cross-cell signaling and/or coordination for interference mitigation in wireless communication networks are described. In one aspect, a UE associated with a serving eNB may receive control signaling from another non-serving eNB in a different cell. The control signaling may be consistent with a characteristic of the serving eNB and associated cell. In another aspect, multiple eNBs may coordinate transmission of DL resources to minimize collisions of control signaling resources.

Methods and apparatus for cross-cell coordination and signaling

User equipment (UE) associated with synchronous networks operate in a synchronous mode while UEs associated with asynchronous networks operate in an asynchronous mode. When operating in a synchronous mode, a UE can significantly improve performance of synchronization signal detection, data decoding, and tracking loop management by using the interference cancellation (IC) techniques that are not available in an asynchronous mode of operation. Obtaining synchronization indicators and determining the synchronization status of the current network by UE is disclosed. The determination may be based on the synchronization indicator, whether detected through signal detection, signal measurements, signal analysis, or the like.
