ESTIMATOR AND METHOD FOR COMPUTING A JOINT POWER BOOSTING PROBABILITY FOR CONTROL CHANNELS SYMBOLS

摘要

The present invention relates to an estimator (100) comprising a processor (102) configured to obtain a received communication signal (y) comprising a control channel symbol (s) transmitted on a plurality of resource elements (RE1, RE2,..., RE_K), a) compute a power boosting probability (p_k) for each resource element (REk) of the plurality of resource elements (RE1, RE2,..., RE_K) based on an estimate (q_k) of the control channel symbol (s) transmitted on the resource element (REk) and an associated variance (δ²_k), b) compute a combined power boosting probability for the plurality of resource elements (RE1, RE2,..., RE_K) based on computed power boosting probabilities for each resource element (REk) of the plurality of resource elements (RE1, RE2,..., RE_K), c) compute a joint probability for the control channel symbol (s) based on the combined power boosting probability. Furthermore, the present invention also relates to a receiving device, a corresponding method, a computer program, and a computer program product.
