摘要： Method and system to dynamically associate spatial layers to beams in a FWA network operating in the millimeter-wave frequency range. A base station (101) and a CPE (102) are willing to wirelessly transmit and receive data through a wireless channel of said FWA network, said base station (101) having beamforming capabilities henceforth generating multiple wireless beams (103). The base station (101) performs all baseband wireless functions related for creating, keeping and managing the connections between the base station (101) and the CPE (102) at baseband level, wherein information is handled in the form of up to M spatial layer signals, and with no built-in capabilities for creation, detection or management of the beams (103). The base station (101) also performs all necessary RF functions at millimeter-wave frequencies, including beamforming and conversion from complex baseband signals to RF signals and vice versa, and also couples the RF signals to said wireless channel.

摘要： A system, method and device for error detection/estimation in OFDM communications systems is proposed. The disclosed mechanism allows an efficient error prediction in a received data block (e.g. a packet) without using error detection codes that may impair spectral efficiency (due to the overhead) especially when very small size packets are used. In order to do that, it generates a decision variable with the aim to check whether a received block has errors or not, without resorting to the use of error-detection codes.

摘要： The network controller (100) is connected to a sub-network (A) of a communication network and comprises: a controller manager (101) that receives a request for a given service, defines forwarding rules related to said service and installs the defined forwarding rules into a computer networking device (120a) in order to configure it for said given service; a deciding module (102) configured to communicate with the controller manager (101) and configured to interact with a DNS server (150) to receive a determined resolution for a DNS request of said request for said given service, and with a database (300) to retrieve information supplementary for the DNS request, in order to assist the controller manager (101) in performing the defining of the forwarding rules; and a plurality of interfaces (S A , S B , S D ) for allowing the communication between the different elements.

摘要： A system (10) implementing a method for determining QoS degradations comprises:
- receiving alarms (a) from application layer (20) or from network nodes (31) of a MPLS network, including Passive Traffic Analyzer (32), Physical Layer Monitoring (33) and MPLS OAM (34) nodes.
- depending on the alarm, the system (10) requests testing (d) for location and the network nodes (31) answer back with location (e),
- once the fault is located, the system (10) starts traffic restoration (h) via MPLS Signaling (35) and receives the result (i),
- the system (10) may need to consult the System Database (36), optionally query (b) - reply (c) step before requesting location, while query (f) - response (g) step is mandatory before restoration (h),
- once traffic restored, further testing by the network nodes (31) and/or the application layer (20) are triggered (j) by the system (10) to ensure the correct overall QoS within the new network situation,
- a loop (i) of further restoration can be triggered by the system (10) until a global stable non-degraded behavior is declared.
