Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may apply transmission power commands and transmit uplink control information based on a received two-stage grant. For example, a UE may receive a grant including a transmit power command that may be applied to a transmission time interval (TTI) during which the UE transmits. The UE may also apply the transmit power command to a TTI that is a number of TTIs after the grant is received. In some cases, the UE may receive a trigger as part of a two-stage grant, and the application of the transmit power command may be based on the trigger. In another example, the UE may identify uplink control information based on a time delay between a number of TTIs. In some cases, a UE may identify control channel elements based on a DCI type.

Abstract: Disclosed embodiments provide an interface circuit for the transfer of data from a synchronous circuit to an asynchronous circuit. Data from the synchronous circuit is received into a memory in the interface circuit. The data in the memory is then sent to the asynchronous circuit based on an instruction in a circular buffer that is part of the interface circuit. Processing elements within the interface circuit execute instructions contained within the circular buffer. The circular buffer rotates to provide new instructions to the processing elements. Flow control paces the data from the synchronous circuit to the asynchronous circuit.

Abstract: Systems and methods are provided that may reduce unnecessary resource consumption and network traffic in a communications network, such as an LTE network. Initiating a tracking area update (TAU) procedure may be avoided in instances where a discontinuous reception (DRX) cycle length chosen by a user equipment (UE) would be ignored in accordance with standards governing paging in the communications networks. To determine whether or not a TAU should be initiated, three parameters may be considered. A first parameter may be the DRX cycle length that is already configured in a mobility management entity (MME). A second parameter may be a DRX cycle length chosen by the UE that the UE wishes to indicate to the MME. A third parameter may be a DRX cycle length that is broadcast by an evolved Node B serving a cell in which the UE is operating.

Abstract: Synchronized UWB piconets for SOP (Simultaneously Operating Piconet) performance. A common backbone (either wired or wireless) is employed that provides a common CLK (clock signal) to all of the various PNCs (piconet coordinators) of various piconets that may operate within a sufficiently close region such that interference could undesirably occur. By providing a very reliable CLK signal from a common backbone to all of the PNCs of the various piconets operating within a substantially close proximity to one another, very precise synchronization may be ensured for all of the communications performed therein. The various piconets may then even operate using TDMA (Time Division Multiple Access)—whose performance would be substantially compromised without effective synchronization. In addition, combined TFC (time frequency code) and TDMA may also be employed to support the communications therein thereby providing even another degree of orthogonality that provided by TDMA alone.

Abstract: A method for avoiding unnecessary excessive stay of short cycle in discontinuous reception mechanism begins by using the short cycle while the short cycle timer is running. Then, it determines whether the inactivity timer expires or not and whether the short cycle timer expires or not. If the inactivity timer expires but the short cycle timer does not expire, the short cycle is used. If the short cycle timer expires but the inactivity timer does not expire, the long cycle is used. If the inactivity timer and the short cycle timer expire at the same time, either the short cycle or the long cycle is selected for use.

Abstract: A numerical controller in which group IDs are automatically allocated to I/O units so that the group IDs and addresses can be set automatically even when a system configuration is changed in response to detection of a configuration error. When a power of the numerical controller is turned on, group IDs are successively allocated to I/O units with distance from the numerical controller, and types of the I/O units are stored. Initial values of the group IDs allocated when the power is turned on for the first time after a system of the numerical controller is constructed, and addresses for the allocated group IDs are stored. An alarm is issued if the types and number of units for the group IDs automatically allocated for the second or later time of starting the numerical controller are different from the initial values.

Abstract: A communication apparatus in an airbag system includes an airbag ECU as a master unit, sets of communication lines and slave sensor devices. The slave sensor devices are respectively connected to the airbag ECU through the set of communication lines. The airbag ECU transmits data transmission request commands to the respective sets of communication lines at timings which are different from each other. Thus, transmission timings in the respective sets of communication lines are prevented from being synchronized, and noise which develops in consequence of the data communications between the master unit and the slave sensor devices can be reduced.

Abstract: A small office/home office base transceiver station includes an acoustic sensor array. Directions from which acoustic signals are detected are presumed to correspond to the interior of the building within which the base transceiver station is located, and with human activity within that interior, while directions from which few or no acoustic signals are detected are presumed to correspond to proximate outside walls. Transmit power gain for directional antenna array elements used for communications are then set to reduce transmission of power in directions that might result in interference with adjacent base transceiver stations.

Abstract: Orthogonal CDMA (OCDMA) in the return link of a satellite based communications system provides improved bandwidth efficiencies; increased ability to overcome channel degrading phenomenon; reduced transmission power; or various combinations thereof. By achieving code synchronization needed for advantageous use of OCDMA in the return link of a satellite based communication system, a plurality of terminals, each with a unique time slot/code channel assignment, may transmit concurrently, with the same, or lower, aggregate power as would be used by a single terminal using TDMA. Use of OCDMA in the return link allows one or more terminals, each in a common beam and assigned a common time slot, to transmit at a higher transmission power to overcome channel degradation effects. The ability to allow for higher transmission power for a particular terminal can increase the effective data rate for that terminal by enabling the use of a higher order modulation technique.

Abstract: A radio (10) with a burst event execution and time synchronization apparatus (16) executes instructions during and after performing time synchronization between a mobile unit and a base station. Both base station (12) and mobile radio (10) have internal timer units (26, 16). Mobile radio (10) timing unit (16) is reset during synchronization between the mobile radio (10) and the base station (12). The control unit (18) writes instructions I(i) including their execution times T(i) to a memory bank (42) within the mobile radio (10). Execution logic (32) within mobile radio (10) executes instruction operands O(i) when execution time T(i) is equal or smaller then a timing count signal received from the timer unit (16). When a time synchronization reset causes the radio (10) time count to jump past queued instructions they can be executed immediately in a burst or delayed until the next communication frame.

The system controller then adjusts the forward channel power allocation based on the comparison results.

Abstract: A microcontroller provides an asynchronous serial port with a serial clock derived from the processor clock. Although the serial clock cannot be exactly programmed to yield an ideal frame length at a particular baud rate, an additional register is provided for tuning the frame length. Each transmitted asynchronous serial frame is stretched by a number of either serial clock phases or processor clocks defined in the tuning register. This provides for improved reception of the asynchronous data, because the frame length more nearly matches the ideal baud rate frame length.

One control signal is assigned bitwise to the control bits of successive bit groups. A starting identification code which is identical for all of the control signals is provided at the beginning of each control signal.

Abstract: A high bit rate start code monitoring, searching and detecting circuit includes a Least Significant Bit (LSB) zero counter, a Most Significant Bit (MSB) zero counter, first and second adders, first and second registers, a comparator, a start code detector, and a start code decoder. The LSB zero counter counts the number of consecutive zero bits from the least significant bit while the MSB zero counter counts the number of consecutive zero bits starting with the most significant bit. A LSB zero count output is added with a prescribed value by the first adder to arrive at a Zero.sub.-- Bits.sub.-- Shifted.sub.-- Out (ZBSO) value, which is saved in the first register. A MSB zero count output is added with the stored value of the ZBSO value during the subsequent clock cycle. If the summed (S) value is greater than or equal to 23, then the start code detector is enabled. The start code detector can detect parts of a start code contained in two separate bitstreams or a start code embedded in a bitstream.

Abstract: An asynchronous serial data receiving device receives serial data, containing main data of bits sandwiched between a start bit and a stop bit, which are transmitted thereto in an asynchronous manner. In the device, the serial data are temporarily stored in a shift register circuit in response to high-speed clocks whose speed is higher than transmission rate of the serial data. A counter circuit counts number of the high-speed clocks. Every time a change of level is detected in the serial data, counting operation of the counter circuit is reset so that the counter circuit re-starts counting from its initial number. The change of level is detected responsive to the serial data or noise. Existence of the start bit is acknowledged on the basis of a fact that the counter circuit continues counting for a window time, without being reset, in a duration of the start bit. Herein, the window time is less than a half of the duration of the start bit.
