Abstract: Wireless telecommunications apparatus and method. A base station sends data to a user terminal on a first channel at a first frequency in selected time slots and the user terminal sends data to the base station at a second frequency in selected time slots. These two frequencies are different. The network also either includes a transmitter which transmits further data to the user equipment at a third frequency in time slots in which the other data is not being sent or includes a receiver which receives further data from the user equipment at the third frequency in time slots in which the other data is not being sent. The apparatus can be a UMTS or other third generation system.

Abstract: In order to double the size of cells for a UMTS/UTRAN system operating in time division mode (TDD) from 3.75 km to 7.5 km, the node B station defines the guard period for a downlink slot followed by an adjacent uplink slot to be longer than the guard period for an uplink slot followed by an adjacent downlink slot, whereby the cell size is extended. Each UE adjusts its timing in reponse to timing deviation signals transmitted at the start of each downlink bust, so as to transmit an uplink burst which arrive at the Node B, at the beginning of the next uplink slot.

Abstract: A telecommunications system for information having a variable structure. The system uses at least one frequency channel for transmitting each second N.sub.T transmission packets to subscriber arrangements. These packets are formed by n.sub.t bits and are allocated to subscriber arrangements themselves producing 1/Ts information packets of n.sub.s bits per second. The system includes a time-division multiplex circuit (10) for multiplexing the information signals coming from subscriber arrangements (SPA1, CIA2, . . . , SPAm . . . ) and, alternatively, a demultiplex circuit (28) for distributing the time-division multiplex information signals to subscriber arrangements. Interleaving circuits are coupled to the multiplex circuit for inserting, into an allocated transmission packet, bits of different information packets allocated to the same subscriber arrangement. De-interleaving circuits coupled to the demultiplex circuit perform the reverse operation.

Abstract: A plurality of subscriber units are connected to at least two transceiver stations for exchanging information in a time division multiple access mode, in which traffic time intervals are allocated in rotation to a variable number C of channels, where C is dependent on the number and type of units to be connected. T intervals plus one control time interval form a frame, where T is mutually prime with respect to the numbers 2 through C.sub.MAX. M frames form a superframe, where M is the lowest common multiple of the numbers 1 through C.sub.MAX.

Abstract: A magnetic resonance signal of a volume of interest within an object is acquired by placing the object in a magnetic field and the application of three successive steps. The first step comprises an rf selective 90.degree. pulse of frequency f.sub.x applied in the presence of an x-gradient magnetic field to select a slice. The magnetization of the slice is then inverted. In the second step an rf selective 90.degree. pulse of frequency f.sub.y is applied in the presence of a y-gradient magnetic field to excite a strip of the slice, in the third step an rf selective 180.degree. pulse of frequency f.sub.z is applied in the presence of a y-gradient magnetic field to refocus the magnetization of a region of said strip. The resulting free induction signal is derived solely from said region.
