Configuring channel-state information resources used for reference-signal-received-power feedback

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.

主权项

1. A method implemented in a wireless network node for determining a set of channel-state-information reference signal (CSI-RS) resources for measurement by a mobile terminal operating in a wireless network, the method comprising:
acquiring a geographical position estimate for the mobile terminal; selecting a set of one or more CSI-RS resources for measurement by the mobile terminal, based on the estimated geographical position; and transmitting control information identifying the selected set of one or more CSI-RS resources to the mobile terminal.
