A
control unit (310) for controlling a
digital interface chip, DIC, (320) of a multi-antenna
transmitter and
receiver arrangement, MATARA, (400), wherein the DIC (320) is connectable via an analog interface (322) to a first plurality of transceivers (500, 501,..., 515) configured to transmit and / or receive radio signals in a first set of frequency ranges (FRa, FRb), wherein the DIC (320) is connectable to one or more
transceiver units (340) via a first
digital interface (342), wherein each
transceiver unit (340) is configured to transmit and / or receive radio signals in a respective set of frequency ranges (FRc, FRd), and wherein the DIC (320) is connectable via a second
digital interface (352) to a
baseband, BB, processor (350) configured to process the radio signals transmitted and / or received in the first and / or in each respective set of frequency ranges (FRa, FRb, FRc, FRd), wherein the DIC (320) comprises a
baseband interface
resource allocation unit, BBIFRA, (360), wherein the BBIFRA (360) is configured to allocate
baseband interface resources for data to be transferred to / from the first plurality of transceivers (500, 501,..., 515) via the analog interface (322) and for data to be transferred to / from the one or more
transceiver units (340) via the first digital interface (342), the
control unit (310) configured to: obtain (110) a configuration of the MATARA (400); allocate (120) a first set of baseband interface resources to the data transmitted / received to / from the first plurality of transceivers (500, 501,..., 515) based on the obtained configuration; allocate (130) a second set of baseband interface resources to data transmitted / received to / from the one or more transceiver units (140) based on the obtained configuration; and configure (140) the BBIFRA (360) to transfer data from the first plurality of transceivers (500, 501,..., 515) and data from the one or more transceiver units (340) to the BB processor (350) via the second digital interface in accordance with the allocated first and second sets of baseband interface resources or to transfer data from the BB processor (150) to the first plurality of transceivers (500, 501,..., 515) and to the one or more transceiver units (340) via the second digital interface in accordance with the allocated first and second sets of baseband interface resources. Corresponding multi-antenna
transmitter and
receiver arrangement, foldable
wireless device, method,
computer program product, and non-transitory computer-readable storage medium are also disclosed.
