A method in a communication device and a communication device (100) for adapting a transmission of data are provided. The transmission is transferred from a first chip (110) to a second chip (120) over a chip-to-chip interface (104, 304). The chip-to-chip-interface comprises a wired connection between the first chip and the second chip which is comprised in the communication device. The communication device receives (201) the radio signal (330), comprising the transmission of data from another communication device. The communication device determines (202), from the received radio signal (330), modulation and coding information, which is used for determining (203) a channel quality. Further, the communication device (100) adapts (204) the transmission of data based on the determined channel quality of the received radio signal (330) in such way that at least the determined channel quality is obtained when transferring (205) the transmission of data over the chip-to-chip interface to the second chip.

A device may include a measurement receiver, a communication receiver, and a transmitter. The measurement receiver may include a receiver (RX) down-conversion component to receive an amplified signal from a low-noise amplifier of the communication receiver, selectively receive a signal from a first local oscillator associated with the communication receiver or a second local oscillator associated with the transmitter, and down-convert the amplified signal to baseband using the received signal from the first local oscillator or the second local oscillator. The measurement receiver may further include a delta-sigma analog-to-digital converter (ADC) to provide low quantization noise only for a particular frequency range to be measured, and a control component to configure the delta-sigma ADC to provide the low quantization noise at the particular frequency range.
摘要:
An electronic system implements a plurality of voltage domains, at least one of which has a selectively variable supply voltage, without requiring the use of a large number of level shifters (e.g., for each data and/or address line). The supply voltage for a first domain is set equal or nearly equal to that of a second domain for a first duration, when the two domains are connected for data transfer across a system bus. When the first domain is isolated from the bus, its supply voltage is set differently from that of the second domain for a second duration. In the second duration, the first domain may have a higher supply voltage, e.g., to perform high-performance computational tasks. Alternatively, it may have a lower supply voltage, to conserve power, if its computational task is less demanding.

The present invention relates to method and arrangement in cellular mobile communication systems, in particular for handling of a physical random access channel for example in a Long Term Evolution communication network. By sending to at least one user equipment, UE, in a communication network cell an un-solicited speculative random access response, RAR, message comprising information relating to at least one of pre-amble identifier, allocated UE identifier, and uplink resource allocation data for L2/L3 message, it is possible to reduce the complexity of the access node, e.g. an eNodeB.

摘要:
Own communication equipment locates a source of wireless transmissions, the own equipment including a serving base station (BS). The serving BS receives, from remote sensors including at least one user equipment (UE), sensing information from which transmitter location information (“location information”) can be determined. The location information is oriented in a serving BS coordinate system. The location information can comprise white space sensing information from which a direction of a transmitter relative to a position of the UE can be determined, and pilot signal sensing information from which respective directions of one or more BSs relative to the position of the UE can be determined. The BS transforms the white space and pilot signal sensing information into the location information. Geographical safety margins are determined from the location information, and BS transmissions are adjusted to limit transmitting signals beyond the geographical safety margin area.
摘要:
Sensing wireless transmissions from a licensed user of a licensed spectral resource includes obtaining information indicating a number of adjacent sensors that are concurrently sensing wireless transmissions from the licensed user of the licensed spectral resource. Such information can be obtained from a main node controlling the sensor and its adjacent sensors, or by the sensor itself (e.g., by means of short-range communication equipment targeting any such adjacent sensors). A sensing rate is then determined as a function, at least in part, of the information indicating the number of adjacent sensors that are concurrently sensing wireless transmissions from the licensed user of the licensed spectral resource. Receiver equipment is then periodically operated at the determined sensing rate, wherein the receiver equipment is configured to detect wireless transmissions from the licensed user of the licensed spectral resource.
