Distributed co-operating nodes using time reversal
Dynamic, untethered array nodes are frequency, phase, and time aligned, and used to focus their transmissions of the same data coherently on a target, using time reversal. Alignment may be achieved separately for the radio frequency (RF) carriers and the data envelopes. Carrier alignment may be by phase conjugation. The data is distributed across the nodes. Data distribution and/or alignment may be performed by a Master node of the array. The nodes capture a sounding signal from the target, in the same time window. Each node converts the captured sounding signal to baseband, for example, using in-phase/quadrature downconversion. Each node stores the baseband samples of the sounding pulse. Each node convolves time-reversed samples of the sounding signal with the data, and upconverts the convolved data to radio frequency. The nodes emit their respective convolved and upconverted data so that the emissions focus coherently at the target.

In the technical solution provided by the embodiments of the present invention, in addition to that the synchronization signal is sent, the supplemental synchronization signal is also sent, and it is equivalent to increase of the transmission frequency of the synchronization signal. In a case where the network coverage is poor, the increase of the transmission frequency of the synchronization signal can increase the probability that the terminal completes cell searching by performing relevant detection on the same number of signals, so as to not only shorten the time required by the terminal to perform cell searching, but also decrease the amount of data buffered by the terminal, thereby decreasing the requirements on the buffer of the terminal.

The gain of the remote units that provide higher power contributions to the combined uplink power in the central unit can be reduced without reducing the gain in the other remote units that would otherwise reduce their sensitivity.

Because the current RRC: ACTIVE SET UPDATE message presently used in soft handover does not contain HS-DSCH related information, which could be utilized for a Serving HS-DSCH cell change, a separate Radio Bearer Control procedure is needed between the UE (10) and the RNC (20) for carrying out the Serving HS-DSCH cell change.

A non-polar, III-Nitride semiconductor fin field-effect transistor (hereafter “finFET”) includes both a fin and a Si(110) silicon substrate, the silicon substrate having a support surface parallel to a Si(110) plane of the silicon substrate. The fin includes a III-Nitride crystalline layer grown along its c-direction, so as to have sidewalls that are parallel to m and a planes of the III-Nitride crystalline layer. The c-direction is parallel to a Si<111> direction of the silicon substrate, such that two opposite ones of said sidewalls are parallel to the support surface of the silicon substrate. Related devices and methods of fabrication are also provided.
P-channel transistor having an increased channel mobility due to a compressive stress-inducing gate electrode
A semiconductor device includes an n channel conductivity type FET having a channel formation region formed in a first region on a main surface of a semiconductor substrate and a p channel conductivity type FET having a channel formation region formed in a second region of the main surface, which second region is different from the first region. An impurity concentration of a gate electrode of the n channel FET has an impurity concentration greater than an impurity concentration of the gate electrode of the p channel FET to thereby create a tensile stress in the direction of flow of a drain current in the channel forming region of the n channel FET. The tensile stress in the flow direction of the drain current in the channel forming region of the n channel FET is greater than a tensile stress in the direction of flow of a drain current in the channel forming region of the p channel FET.
