Methods and devices for allocating uplink control resources and transmitting uplink control information

The invention discloses methods and devices for allocating uplink control resources and transmitting uplink control information. The method for transmitting uplink control information comprises that: a terminal acquires the shift interval of a cyclic shift sequence, the resource number for feeding an acknowledgment (ACK) / a negative acknowledgment (NACK) back and an ACK / NACK feedback mode; according to the shift interval of the cyclic shift sequence and the resource number for feeding ACK / NACK back, the terminal determines an available spread spectrum sequence for feeding the ACK / NACK back, wherein the spread spectrum sequence comprises a cyclic shift sequence and an orthogonal sequence; and after receiving downlink data, the terminal transmits the ACK / NACK information to be fed back in the ACK / NACK feedback mode in an uplink control channel by using the available spread spectrum sequence. Thus, the transmission of many pieces of ACK / NACK information in one uplink control channel is realized in a system for realizing long-term evolution multi-carrier aggregation.

Method of fabricating bottle trench capacitors using an electrochemical etch with electrochemical etch stop

A method of forming trench capacitors in, e.g., a DRAM device, using an electrochemical etch with built-in etch stop to fabricate well-defined bottle-shaped capacitors is described. The process includes formation of a sacrificial silicon layer after initial deep trench formation, wherein the sacrificial layer is formed by doping, and upon its removal, a bottle trench is formed. A second region of doped silicon located below the sacrificial layer is resistant to the chemical etch performed to remove the sacrificial layer, and thereby renders the bottle trench formation process self-limiting.

Assembly for purifying water

An ozone-based water purification system is disclosed. In this system, a mixing venturi injects ozone and a liquid sanitizer into a stream of water to be treated. Following ozone and sanitizer injection, the stream of water is passed to a contact region where the ozone and sanitizer are allowed to react with contaminants and biota. The stream is then mixed by several mixing devices to allow residual ozone and sanitizer to further react with contaminants and biota. Particularly a counterflow system is employed wherein the stream is directed downward at several points so that bubbles containing ozone are forced to flow upward against the flow, lengthening ozone contact time. Also, the ultraviolet lamp used to generate ozone is mounted so that ultraviolet light therefrom is exposed to the flow water, providing additional sterilizing effects. In addition, a novel mixing venturi is disclosed that mixes a gas containing ozone and a liquid sanitizer into a motive flow of water.
