摘要： Methods and apparatus are disclosed for reducing mobile terminal energy consumption during data transmissions by allocating link resources and adapting link parameters in an energy-aware manner, based on throughput requirements and prevailing channel conditions. A combination of transmit parameters that includes a transmit channelization scheme and is designed to minimize the total energy consumed during data transmission is selected based on a throughput requirement and one or more channel conditions associated with the data transmission. The channelization scheme includes a number of subchannels to be used and subchannel configuration parameters for each subchannel, such as spreading codes, spreading factors, and subchannel power levels.

摘要： A wireless communication system receiver receives and processes a signal comprising at least two component carriers carrying data scheduled to the receiver and having center frequencies spaced apart by at least one component carrier frequency difference. Each component carrier comprises a number of subcarriers spaced apart by a system subcarrier frequency spacing. A common divisor is obtained for the at least one component carrier frequency difference and the system subcarrier frequency spacing. A symbol is received on the subcarriers of the component carriers and downconverted to baseband to produce a baseband symbol. A block of padding values is inserted in the baseband symbol to produce a padded symbol. The length of the block of padding values is such that intermediate subcarriers are inserted to yield a subcarrier frequency spacing for the padded symbol equal to the common divisor. Finally the padded symbol is Fast Fourier Transform, FFT, processed.

摘要： Methods and apparatus for changing the transmission/reception setup of a base station (BS) in a communication network to another transmission/reception setup (such as one using fewer transmit antennas and/or lower channel bandwidths) without affecting communication with user equipments involve “replacing” the existing BS with a “virtual” BS that has the other transmission/reception setup. Replacement can be performed by, for example, ramping down the power of the existing, or first, BS, which has a respective first cell identification (ID), and simultaneously ramping up the power of the virtual, or second, BS, which has a respective second cell ID.

摘要： A processing device (40) for processing an analog complex input signal generated by downconversion of an aggregated-spectrum radio-frequency signal in a radio-receiver (10), wherein the complex input signal comprises a plurality of sub bands (S1-S4) scattered across a total frequency band (4) of the complex input signal. The processing device (40) comprises a plurality of processing paths (P1-PN). wherein each processing path (P1-PN) is adapted to process an associated sub band (S1-S4). Each processing path comprises a complex mixer (CM1-CMN) adapted to frequency translate the complex input signal, and an analog channel-selection filter (CSF1-CSFN) arranged to filter an output signal of the complex mixer (CM1-CMN) and pass the frequency translated associated sub band (S1-S4). A control unit (60) is adapted to receive control data indicating frequency locations of the sub bands (S1-S4) and, for each processing path (P1-PN). control the local oscillator signal of the complex mixer (CM1-CMN) of the processing path (P1-PN) based on the frequency location of the associated sub band (S1-S4) and the passband of the channel-selection filter (CSF1-CSFN) of the processing path (P1-PN), such that the frequency-translated associated sub band (S1-S4) appears within a passband of the channel-selection filter (CSF1-CSFN) of the processing path (P1-PN). The distortion monitored in the unused paths may be used to improve the performance of the used paths.

摘要： Ascertaining a signal power of an Orthogonal Frequency Division Multiplexing (OFDM) signal involves ascertaining a plurality of channel estimates from the OFDM signal. Compensating phase shift values for phase aligning the plurality of channel estimates are estimated and used to generate phase corrected channel estimates. The phase corrected channel estimates are coherently combined, thereby ascertaining the signal power of the OFDM signal. The compensating phase shift values may be based on a channel characteristic (e.g., delay spread) or may alternatively be hypothesized.
