Title: Transmitting a data signal in a wireless communication system with reduced through delay
Inventor: HELLGE CORNELIUS
IPC: H04L27/26
Filed: 2019-08-02
Granted: 2020-07-30
Abstract: FIELD: wireless communication equipment.SUBSTANCE: invention relates to the field of wireless communication systems, for example wireless mobile communication systems, in which data are transmitted from a transmitter to one or more receivers. This implies reducing the length of the TTI so that the UE can start demodulating the data after receiving the full short TTI. TTI length can be reduced to one OFDM symbol in time. Subframe format (propagation of reference symbols, control symbols and payload) is changed so as to ensure constant payload speed on TTI (that is 10 subcarriers out of 12 at RB for each time symbol are allocated to payload). Two additional ideas affect the TTI length signaling inside the so-called Basic Information Unit and the scenario of simultaneous aggregation of TTI mixed-length carriers. According to one embodiment, the receiver is configured to receive a data signal, which data signal comprises at least one data signal unit, wherein the data signal unit has a predetermined duration in the time domain, a number of symbols in the time domain and bandwidth in the frequency domain, wherein the data signal unit is received in a plurality of transmission intervals, wherein the length of one transmission interval is shorter than the duration of the data signal unit such that the subscript of the data signal unit symbols is received in one transmission interval, and wherein receiver comprises signal processing device configured to process symbols of data signal unit, which were received in one transmission interval.EFFECT: technical result is reduction of delay (less than 1 ms) for services of Ultra Low Delay (ULD) so-called 5G.16 cl, 24 dwg

Abstract: Предлагаемое изобретение относится к области навигации космических аппаратов (КА). Способ определения угловой ориентации КА по сигналам навигационных спутников (НС) включает излучение радиосигналов от НС с известными параметрами орбиты, формирование и выдачу команд на прием сигналов выбранных НС на каналы приемного устройства, установленного на КА, выделение каждым каналом приемного устройства из суммарного сигнала всех НС сигналов спутников, соответствующих выданным командам и прием этих сигналов при условии нахождения соответствующих спутников в поле зрения одной из n антенн приемного устройства с известными единичными непараллельными векторами направлений центральных осей антенн относительно связанной системы координат КА. Определение текущих координат КА по принимаемым сигналам НС, измерение интегральных фаз одного и того же j-го НС из общего созвездия спутников, видимых i-й парой антенн. При этом исключается необходимость раскрытия фазовой неопределенности за счет проведения серии фазовых измерений при стабилизации КА по приращениям интегральных фаз одних и тех же НС текущего созвездия i-й пары антенн. Ориентация определяется на момент первого измерения серии и преобразовывается к текущему моменту времени. Технический результат заключается в определении ориентации КА только по измерениям аппаратуры спутниковой навигации (АСН) без использования измерений от других систем при произвольной неизвестной ориентации КА. 2 ил.

Abstract: FIELD: physics. 
     SUBSTANCE: invention discloses silicon carbide switching device and its manufacturing method; device is used to reduce the ratio of resistance of the channel to resistance of the device in an on state. According to the present invention, the upper structure of the device is twice subjected to epitaxial growth processing, wherein the impurity concentration of the secondary epitaxial channel area is lower than in the region of lateral doping of the pocket of the P-type; impurity concentration of the secondary epitaxial N+ area is much higher than in the region of lateral doping of the P-type pocket; concentration of admixture of N+ area is much higher, than in area of lateral alloying of pocket of P-type. Due to such structure, channel length on side wall of secondary epitaxial channel area depends on thickness of epitaxial growth. Switching on/off of the device according to the present invention is carried out by means of two methods. Channel on the side wall of the secondary epitaxial channel area is very short, and the current path of the epitaxial drift layer can be switched off under condition of generation of sufficiently high voltage drop during disconnection without allowance for the channel closing effect at high voltage; respectively, present invention has great advantages in comparison with previous level of equipment; at the same time, a wide current path of the epitaxial drift layer is used and a positive preset voltage is maintained, which provides advantages of the present invention compared to a standard silicon carbide-effect transistor with a control p-n junction. 
     EFFECT: invention discloses silicon carbide switching device and its production method.
