摘要： Disclosed is a method performed by a base unit (170) of a base station system (100) of a wireless communication network for handling antenna signals for transmission over a transmission connection (165) between the base unit (170) and a remote unit (160) of the base station system. The method comprises receiving IQ samples of a first antenna signal related to wireless communication of a first antenna (161) of the remote unit (160), and IQ samples of a second antenna signal related to wireless communication of a second antenna (162) of the remote unit (160), transforming the received IQ samples of the first antenna signal into transformed IQ samples, using a first transformation value, and transforming the received IQ samples of the second antenna signal into transformed IQ samples, using a second transformation value different from the first transformation value. The method further comprises quantizing the transformed IQ samples of the first antenna signal using fewer bits, and quantizing the transformed IQ samples of the second antenna signal using fewer bits, and transmitting the quantized and transformed IQ samples of the first and the second antenna signal over the transmission connection (165) to the remote unit (160) for subsequent de-quantizing and re-transforming of the quantized and transformed IQ samples of the first and the second antenna signal into the received IQ samples at the remote unit.

摘要： A first network node(11) of a cellular system for communication with a second network node (21) over a twisted pair wire (23). The first network node comprises a receiver (123) for receiving, over the twisted pair wire, an intermediate frequency signal from the second network node, which intermediate frequency signal has been converted from a high frequency signal having a frequency higher than the frequency of the intermediate frequency signal by the second network node, and a down-converter (121) for converting the intermediate frequency signal to a low frequency signal having a frequency lower than the frequency of the intermediate frequency signal. The first network node also comprises an up-converter (122) for converting a received low frequency signal to an intermediate frequency signal having a frequency higher than the frequency of the low frequency signal, and a transmitter (124) for transmitting, over the twisted pair wire, the intermediate frequency signal to the second network node for subsequent conversion into a high frequency signal with a frequency higher than the frequency of the intermediate frequency signal at the second network node. The invention also relates to corresponding methods for taking care of downlink signals and uplink signals, respectively.

摘要： A supporting radio base station (100) comprises an IQ sample provider (110) for extracting, in a selected subset of the available frequency band (A) and/or from a selected subset of the available antennas (B), so-called complementary IQ samples based on received radio signals including a radio signal originating from an uplink transmission of at least one UE served by a serving radio base station (200). The supporting radio base station (100) comprises an IQ sample transmitter (120) for transmitting the complementary IQ samples to the serving radio base station (200) to enable the serving radio base station to decode user data of the uplink transmission based on the complementary IQ samples together with own IQ samples provided by the serving radio base station (200). This will provide significant savings of bit rate for the exchange of IQ samples between the radio base stations.

摘要： A data communication scheduling system (300) of a radio base station (100) serving multiple cells (10-30) comprises multiple radio equipment, REs, (101-103) and antenna interfaces (115, 125, 135) connectable to antennas (110, 120, 130). In order to reduce the power consumption, only a subset of the RE (101) is active, while the other REs (102, 103) are turned off. A transmitter controller (155) is arranged for controlling the active RE (101) to be shared among multiple cells (10-30) during a radio frame (40) so that each cell (10-30) is guaranteed at least one sub frame (50-58) for downlink transmission. A receiver antenna system multiplexer(140) selectively interconnects the active RE (101) with the antenna interfaces (115, 125, 135) according to the operation of a receiver controller (145). Consequently, the RE (101) becomes connected to different antenna interfaces (115, 125, 135) during different sub frames (50-58) to thereby allow each cell (10- 30) at least one assigned uplink sub frame (53-55) in the radio frame (40) at a predefined sub frame distance after the at least one downlink sub frame(50-52) assigned to the same cell (10-30).

摘要： A method for operating a radio access system comprises configuring (S1) a first carrier and a second carrier for use for radio access in a first radio access system. The second carrier is configured for frequency division duplex signalling. A useful frequency band of the second carrier is defined to, at least partially, overlap in frequency with a useful frequency band of a third carrier of a second radio access system. At least a part of the useful frequency band of the second carrier overlaps in frequency with guard bands of the third carrier. A method for signal scheduling comprises scheduling, in a first radio access system having a first carrier with a first carrier frequency band and a second carrier with a second carrier frequency band, uplink signals in the second carrier. Network nodes for carrying out the methods are also presented.
