    Abstract: A user equipment (UE) for time division duplex (TDD) communication through a wireless communication channel has a receiver to receive a channel state information reference signal (CSI-RS) subframe configuration value, a CSI-RS configuration value, and a CSI-RS; and circuitry to determine a subframe index corresponding to a temporal position of a special subframe including the CSI-RS; determine a CSI-RS pattern of one or more orthogonal frequency division modulation (OFDM) resource elements carrying the CSI-RS, the pattern being from among a group of CSI-RS patterns that include OF DM resource elements in OFDM symbols corresponding to a physical downlink control channel (PDCCH) region of a legacy LTE wireless communication channel; control the receiver to receive the special subframe carrying the CSI-RS during the temporal position and at the one or more OFDM resource elements of the CSI-RS pattern; and measure the wireless communication channel based on the CSI-RS.

    Abstract: Cyclic deposit and etch (CDE) selective epitaxial growth employs an etch chemistry employing a combination of hydrogen chloride and a germanium-containing gas to provide selective deposition of a silicon germanium alloy at temperatures lower than 625° C. High strain epitaxial silicon germanium alloys having a germanium concentration greater than 35 atomic percent in a temperature range between 400° C. and 550° C. A high order silane having a formula of SinH2n+2, in which n is an integer greater than 3, in combination with a germanium-containing precursor gas is employed to deposit the silicon germanium alloy with thickness uniformity and at a high deposition rate during each deposition step in this temperature range. Presence of the germanium-containing gas in the etch chemistry enhances the etch rate of the deposited silicon germanium alloy material during the etch step.

    Abstract: In accordance with some embodiments, in a time division duplex system, the transmission direction may be changed dynamically, for example in response to instantaneous traffic conditions. Particularly in some embodiments an eNodeB or base station may, in response to instantaneous traffic conditions, change the direction of transmission in certain subframes. In some embodiments this can be done in a way which is backwards compatible with prior generations of Long-Term Evolution (LTE) radio systems.

    Abstract: Technology for synchronization of uplink transmission with multiple timing advances in a wireless communication environment is disclosed. Additional resource allocation messages for additional timing advances are addressed to a user equipment specific search space. A number of band decodes needed to find a resource allocation message used to access an additional timing advance can be reduced by padding the resource allocation message. A number of blind decodes used to find the resource allocation message can also be reduced by restricting the control channel candidates in which the resource avocation can be embedded in terms of the control channel element aggregation level, or levels, associated with acceptable control channel candidates.
