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.

Abstract: A method and apparatus for power control for wireless transmissions on multiple component carriers corresponding to multiple serving cells associated with multiple timing advances are disclosed. A wireless transmit/receive unit (WTRU) may determine transmit powers for a first physical channel for a first serving cell in a first timing advanced group (TAG) and a second physical channel for a second serving cell in a second TAG. The first TAG may less timing advanced than the second TAG. The WTRU may determine a WTRU configured maximum output power (PCMAX) for an overlapping portion, which may be a portion of a transmission of the first channel in a first subframe that overlaps in time with a portion of a transmission of the second channel in a next subframe. The WTRU may adjust the channels such that a sum of their transmit powers in the overlapping portion does not exceed the determined PCMAX.
