Abstract: According to the teachings herein, a wireless device enhances uplink channel estimation at a node in a supporting wireless communication network by beamforming its uplink reference signal transmission towards the node, and correspondingly compensates for the effect of that beamforming when receiving a downlink transmission that was adapted in dependence on the uplink channel transmission. Such processing provides significant advantages in Multiple-Input-Multiple-Output, MIMO, systems that use a potentially large number of antennas for downlink MIMO transmissions and assume reciprocity between the uplink and downlink channels. In particular, uplink beamforming increases the received signal quality of the uplink reference signal used for estimating the uplink channel, while “automatic” compensation by the wireless device of the corresponding downlink transmission obviates the need for the network to know which precoder was used for uplink beamforming, or even that uplink beamforming is in use.

Abstract: According to the teachings herein, a wireless device that is a candidate for operating in the cooperative positioning advantageously activates that mode in response to detecting a warning situation. In some embodiments, the detection and/or activation operations are autonomously undertaken by the wireless device.

More generally, the wireless communication network maintains a database identifying those wireless devices within a given service area that are cooperative positioning mode candidates—e.g., the devices having D2D communication capability and operational configurations that allow such operation. By the network providing such information in advance of a warning situation, the candidate devices have the information needed to efficiently discover or otherwise identify other such candidates.
