摘要： In a first aspect the present invention relates to a method of compensating for propagation delay in a wireless communication system. A first base station is in communication with a first plurality of antenna units which are adapted to be in wireless communication with a first terminal. The first terminal having a terminal antenna. The first plurality of antenna units is spatially separated. The method according to the first aspect comprises the steps of determining relative propagation delay from each of the first plurality of antenna units to the terminal antenna and using the determined propagation delay to establish a delay profile to compensate for propagation delay from each of the antenna units to the first terminal and applying the delay profile to a transmission between the base station and the terminal. In a second aspect the present invention further relates to a system implementing the method according to the first aspect.

摘要： The initialization of the CoMP Resource Management Set for a given mobile terminal is based, at least in part, on an estimation of the mobile terminal's geographical location, which can be estimated using network positioning of the mobile terminal. One example method begins with the acquisition (410) by a network node of a geographical position estimate for the mobile terminal of interest. The network node then selects (420) a set of one or more CSI-RS resources for measurement by the mobile terminal, based on the estimated geographical position of the mobile terminal. Finally, the network node configures the mobile terminal to measure the selected CSI-RS resources by sending (430) control information identifying the set to the mobile terminal.
