Abstract: It is provided a method comprising monitoring if a reservation request is received from a controller, wherein the reservation request requests to reserve resources for a data session having a first quality of service; translating the reservation request into a request for providing a data session of a wireless network having a requested quality of service corresponding to the first quality of service if the reservation request is received; forwarding the request for providing the data session to the wireless network; translating an indication of a provided quality of service of the data session comprised in a response to the request for providing the data session received from the wireless network into an indication of a reserved quality of service corresponding to the provided quality of service; responding to the reservation request by a reservation response; wherein the reservation response comprises the indication of the reserved quality of service.

Abstract: For a system with multiple Antenna Elements, AEs, to be used to transmit multiple symbols to multiple user equipments, UEs, and with multiple time sample positions, where the symbols occupy a time-frequency resource space and wherein at least some of the AEs are powered by constrained RF chains having functionalities that are simplified relative to full RF chains, precoder coefficients are generated for the multiple AEs taking into consideration multipath components of a signal to be transmitted from the multiple AEs to the multiple UEs. The generating forms precoder coefficients for individual ones of the constrained RF chains at corresponding certain time sample positions of the symbols. The signal is transmitted from the multiple AEs to the multiple UEs using FDMA at least by applying the generated precoder coefficients to the multiple AEs over the multiple time sample positions and time-frequency resource space of the symbols.

Abstract: A method is provided for channel estimation of an antenna array comprising multiple antenna elements. The method comprises obtaining channel state information for antenna elements with a high-end radio frequency chain, wherein the antenna elements with the high-end radio frequency chain are placed in the antenna array intermittently with antenna elements with a low-cost radio frequency chain. Channel state information is estimated for the antenna elements with the low-cost radio frequency chain, by interpolating the channel state information obtained for the antenna elements with the high-end radio frequency chain.
