    摘要： Embodiments of an enhanced Node B (e NB) configured for use in a cooperative radio access networks (C-RAN) and method for central baseband unit (BBU) processing are generally described herein. In some embodiments, the eNB may include a baseband unit (BBU) processing pool comprising a plurality of processing units. The BBU processing pool is configured to share the processing load of several sectors. A control unit may monitor the processing load of the processing units and perform dynamic load sharing by migrating the baseband processing between the processing units without changing a carrier used by user equipment operating with a sector.

    摘要： Various strategies and devices are disclosed to correct frequency offset (such as due to differing accuracies between an oscillator of a transmitting device and an oscillator of a receiving device) and Doppler shift (such as due to a changing relative position between a receiving device and a transmitting device). These strategies may be employed in a MIMO setting, such as, e.g. a stationary base station and a plurality of terminal devices (e.g. user devices, mobile stations, etc.), in which the transmissions for each terminal device may be associated with a different frequency offset and a different Doppler shift.

    摘要： A system and methods for estimating a noise power level in an uplink signal for a virtual MIMO system is disclosed. The system comprises a demodulation reference signal (DMRS) module configured to obtain a DMRS receive symbol from the uplink signal and determine a DMRS sequence for a first UE in the virtual MIMO system. An autocorrelation module is configured to calculate an average autocorrelation value for the subcarriers in the uplink signal. A cross-correlation module is configured to calculate first and second cross-correlation values of the uplink signal R
    z (
    l ) for values of
    l selected such that the sum of the received power from the first UE and the second UE can be accurately estimated. A noise power level module is configured to determine the noise power level for the uplink signal using the average autocorrelation value and the first and second cross correlation values.
