An information processing method performed by a base station for establishing a communication connection with a destination user terminal, comprising: determining N first regions centred on the base station, the N first regions determined based on respective N first thresholds, the N first thresholds each representing an outage probability of a first communication connection between the base station and a user terminal within the respective first region; determining T third regions comprising identifying an overlap region between the N first regions and M second regions, the M second regions being centred on the destination user terminal and determined based on respective M second thresholds, the M second thresholds each representing an outage probability of a second communication connection between the destination user terminal and a candidate relay terminal within the respective second region, wherein N and M are integers greater than 1; characterized in that the method comprises: selecting a candidate relay user terminal from among user terminals within a target third region selected in a descending order of priority of the T third regions, to establish a relay communication connection between the base station and the destination user terminal through the relay user terminal, wherein, a priority of the target third region is identified (207, 307) based on the first threshold and the second threshold corresponding to the target third region, and a higher priority of the target third region is associated with a smaller first and second threshold. determining N first regions centred on the base station, the N first regions determined based on respective N first thresholds, the N first thresholds each representing an outage probability of a first communication connection between the base station and a user terminal within the respective first region; determining T third regions comprising identifying an overlap region between the N first regions and M second regions, the M second regions being centred on the destination user terminal and determined based on respective M second thresholds, the M second thresholds each representing an outage probability of a second communication connection between the destination user terminal and a candidate relay terminal within the respective second region, wherein N and M are integers greater than 1; characterized in that the method comprises: selecting a candidate relay user terminal from among user terminals within a target third region selected in a descending order of priority of the T third regions, to establish a relay communication connection between the base station and the destination user terminal through the relay user terminal, wherein, a priority of the target third region is identified (207, 307) based on the first threshold and the second threshold corresponding to the target third region, and a higher priority of the target third region is associated with a smaller first and second threshold. selecting a candidate relay user terminal from among user terminals within a target third region selected in a descending order of priority of the T third regions, to establish a relay communication connection between the base station and the destination user terminal through the relay user terminal, wherein, a priority of the target third region is identified (207, 307) based on the first threshold and the second threshold corresponding to the target third region, and a higher priority of the target third region is associated with a smaller first and second threshold.
