Abstract
In some embodiments, a node associated with a distributed antenna wireless system obtains one or more combined receive signals responsive to a transmission by the wireless device. The distributed antenna wireless system comprises multiple Remote Radio Heads (RRHs) each comprising one or more receivers. Each receive branch of one or more receive branches of the distributed antenna wireless system comprises a combination of one receiver from each of the RRHs. The one or more combined receive signals comprise, for each receive branch, a combined receive signal that is a combination of signals received by the receivers comprised in the receive branch in accordance with different simultaneous ON/OFF patterns assigned to the RRHs for the receive branches. The node analyzes the one or more combined receive signals to determine information indicative of a geographic location of the wireless device.
