Abstract:
A signal transmission method in a Time Division Duplex (TDD) system is disclosed. The method comprises following steps: within a time length of a half-frame of a radio frame, base station transmits signal on a downlink special time slot, thereafter does not transmit signal on a Guard Period (GP), and then receives signal on an uplink special time slot; all time lengths of other uplink or downlink normal time slots for transmitting signal are equal; the total time length of the downlink special time slot, the guard period and the uplink special time slot is integer times of the time length of an uplink or downlink normal time slot. In addition, a frame structure adopted in the TDD system which corresponds to the method is disclosed. The present invention makes it flexible to set the duration of the GP and it is guaranteed that, even if a synchronization signal adopts power promotion, it will not bring great interference to uplink reception of other base stations; in addition, the utilization efficiency of the system is improved.
Abstract:
The present invention provides a method for determining the number of random access channels which is applied to a time division duplex system. The method comprises: a terminal determining configuration parameters related to the number of the random access channels in an UpPTS based on system configuration, said configuration parameters including the number of downlink-to-uplink switch-points in one radio frame NSP, the density of PRACHs in a random access configuration DRA, a system frame number of a system frame in which said UpPTS is located nf, and a version index corresponding to a PRACH configuration index rRA; and said terminal then calculating directly the number of the PRACHs in said UpPTS based on the configuration parameters. The present invention also provides a method for sending a SRS of a time division duplex system using the method for determining the number of the random access channels.

Abstract:
There is provided a dock without a power source for a portable digital device with at least one integrated speaker driver. The dock may include a platform for placement of the portable digital device; a protrusion located at the platform for connection of the portable digital device with the dock with the protrusion including a slot for egress of air from at least one hole in a casing of the portable digital device to the dock; and at least one primary chamber to receive air from the portable digital device with the at least one primary chamber having a vented port for the egress of air. Advantageously, sound from the at least one integrated speaker driver is amplified when the portable digital device is connected to the dock. The connection of the portable digital device with the dock may be securable. A horn may be included in an exterior facing opening of the vented port, as the horn advantageously improves aspects of sound such as, for example, sound directivity, radiation efficiency or both of the aforementioned.
Abstract:
A terminal random access method for a cellular radio communications system and a method for generating a group identifier are provided. The terminal random access method for a cellular radio communications system includes steps of: transmitting random access preamble message by a terminal to a base station in a random access time slot in a radio frame; combining location information of the random access time slot in the radio frame and that in the frequency domain to generate a group identifier and sending a random access response message to the terminal after adding the group identifier and an individual identifier that corresponds to the random access preamble message to the random access response message by the base station; judging whether the random access response message that corresponds to the sent random access preamble message is received, by judging whether the group identifier and the individual identifier within the received random access response message are all expected values. This invention provides fast and accurate access to the cellular radio communications system for the terminal and allows simple and easy operations to set a group identifier in the same way regardless of whether or not the configuration of the random access time slot changes.

Abstract:
A real-time method employing a portable peptide-containing potentiometric biosensor, can directly detect and/or quantify bacterial spores. Two peptides for specific recognition of B. subtilis and B. anthracis Sterne may be immobilized by a polysiloxane monolayer immobilization (PMI) technique. The sensors translate the biological recognition event into a potential change by detecting, for example, B. subtilis spores in a concentration range of 0.08-7.3×104 CFU/ml. The sensing method exhibited highly selective recognition properties towards Bacillus subtilis spores over other kinds of spores. The selectivity coefficients of the sensors for other kinds of spores are in the range of 0-1.0×10−5. The biosensor method not only has the specificity to distinguish Bacillus subtilis spores in a mixture of B. subtilis and B. thuringiensis (thur.) Kurstaki spores, but also can discriminate between live and dead B. subtilis spores. Furthermore, the sensing method can distinguish a Bacillus subtilis 1A700 from other B. subtilis strain. Assay time may be as low as about 5 minutes for a single test. Rapid identification of B. anthracis Sterne and B. anthracis ΔAmes was also provided.
