A method performed by the cooperating network node comprises receiving an uplink signal from a wireless device, the uplink signal comprising data. The method further comprises compressively sampling the data so as to obtain compressive measurements of the data. The method further comprises transmitting the compressively sampled data to the coordinating network node. There is also provided a method performed in the coordinating network node. There is further provided a cooperating network node and a coordinating network node arranged to perform the methods and computer programs and computer program products comprising computer program code for implementing the method.

Abstract: Embodiments are directed to improving uplink transmission properties in a communication network. In one aspect a method for improving uplink transmission properties is disclosed that includes: obtaining information indicating an operating scenario of a UE, wherein the UE includes a plurality of antennas and the UE is configured to transmit UL signals using the plurality of antennas; selecting a precoder that is optimized for UL multiple antenna transmission based on at least the indicated operating scenario; and communicating the precoder to the UE. The information indicating an operating scenario comprises information indicating one or more of: i) a deployment characteristic on which the UE operates, ii) a cell change scenario, iii) a radio transmission characteristic of the UE, iv) a number of links that are involved in UL transmissions from the UE, and v) a type of service used by the UE.

Abstract: Detection of OFDM symbols generates an equivalent vector which represents the sufficient statistics (SS) which are subsequently processed using a maximum likelihood (ML) algorithm. The algorithms and implementations are described. Both examples of implementation using the A* (ML) algorithm and a near-ML trellis search algorithm for a time-varying finite state machine model of the received vector of SS are described.
