    摘要: Techniques are provided for providing Doppler correction. In particular, embodiments may provide re-banding circuitry having a reference clock, a mixer, and a compensation circuitry for re-banding and for Doppler correction. The compensation circuitry may be configured to adjust a reference frequency of the reference clock based on signals received from a Global Navigation Satellite System (GNSS) receiver. The mixer may be configured to translate communication signals in a first frequency band to a second frequency band based at least in part on the adjusted reference frequency of the reference clock.

    摘要: Aspects of the subject disclosure may include, for example, a coupling device including a first antenna that radiates a first RF signal conveying first data; and a second antenna that radiates a second RF signal conveying the first data from the at least one transmitting device. The first RF signal and second RF signal form a combined RF signal that is bound by an outer surface of a transmission medium to propagate as a guided electromagnetic wave substantially in a single longitudinal direction along the transmission medium. Other embodiments are disclosed.

    摘要: The invention discloses a method and a base station for phase compensation in beamforming in a multi-antenna Time Division Duplex (TDD) communication network. In a first transmission mode, e.g. TM4 or TM8, the base station estimates a first phase shift between a first antenna port and a reference antenna port in uplink based on a measurement of a first Sounding Reference Signal (SRS). Then the base station estimates in the first transmission mode a second phase shift between the first antenna port and the reference antenna port in downlink based on a Channel State Information (CSI) feedback from a User Equipment (UE), and calculates a parameter indicative of a difference between the first phase shift and the second phase shift. In a second transmission mode, e.g. TM7 or TM8, the base station estimates a third phase shift between the first antenna port and the reference antenna port in uplink based on a measurement of a second SRS, and calculates in the second transmission mode, a fourth phase shift between the first antenna port and the reference antenna port in downlink as a difference between the third phase shift and the parameter. The base station then compensates in the second transmission mode, the phase of input signal on the first antenna port by the fourth phase shift for beamforming.
