Abstract: A wireless transmit/receive unit (WTRU) is configured to receive a reference signal of a first type. The reference signal of the first type is other than a cell specific reference signal (CRS), an Multicast Broadcast Single Frequency Network (MBSFN) reference signal or a demodulation reference signal (DM-RS). Reference signals of the first type are received in resource elements other than resource elements used for a physical broadcast channel (PBCH), a primary synchronization signal or a secondary synchronization signal. The WTRU is configured to receive a radio resource control message indicating a subframe position in which the reference signal of the first type is transmitted and a periodicity of a transmission of the reference signal of the first type, and a number of antenna ports for a transmission of the reference signal of the first type.

Abstract: Methods and apparatus for supporting reference signals for positioning measurements are disclosed. Methods include subframe configuration, subframe structures, measurement opportunities using a set of downlink subframes which are not all consecutive, handling of subframes containing reference signals and system signals such as synchronization signals, paging occasions and Multicast Broadcast Multimedia Service (MBMS), and related control signaling between a long term evolution (LTE) network and a wireless transmit/receive unit (WTRU). Moreover, methods to resolve allocation conflicts arising between positioning reference signals and other reference signals are disclosed.
