Abstract
Different solutions, in which uplink data streams are whitened and after that combined, are disclosed. The whitening is performed by applying whitening parameters received in a downlink control information. The whitening parameters are based on predictions on channel conditions.
Claims14
An apparatus, comprising:
- at least one processor;
- and
- at least one non-transitory memory storing instructions that, when executed with the at least one processor, cause the apparatus to perform:
- receiving, with a first apparatus, in a downlink control information, whitening parameters;
- receiving at least from a second apparatus one or more first uplink data streams;
- applying the whitening parameters at least on the one or more first uplink data streams resulting to one or more whitened first uplink data streams;
- performing one of forwarding, to the first apparatus, the one or more whitened first uplink data streams to be combined at least with one or more whitened second uplink data streams, or combining the one or more whitened first uplink data streams at least with the one or more whitened second uplink data streams and forwarding, to the first apparatus, one or more combined uplink data streams wherein the combining comprises selecting a subset of the one or more whitened first uplink data streams and the one or more whitened second uplink data streams and combining whitened uplink data streams in the subset.

An apparatus, comprising:
- at least one processor;
- and
- at least one non-transitory memory storing instructions that, when executed with the at least one processor, cause the apparatus to perform:
- receiving, from a fourth apparatus, a request for whitening parameters for one or more uplink data streams predicted to be received with one or more second apparatuses over a radio interface and to be whitened before combined to one or more combined uplink data streams;
- deriving predictions for the whitening parameters based at least on a predicted channel condition in the radio interface for the one or more data streams;
- and
- transmitting, with at least the fourth apparatus, in downlink control information, the predictions as the whitening parameters for the one or more uplink data streams to be whitened.
