Abstract: A method and apparatus are described for controlling uplink (UL) transmission power. A wireless transmit/receive unit (WTRU) may receive a configuration of UL subframe sets and maintain a plurality of transmit power control (TPC) command accumulator values that correspond to respective ones of the UL subframe sets. The WTRU may receive a TPC command in a subframe n of a downlink (DL) transmission, determine a subframe n+k of a UL transmission that the received TPC command corresponds to, determine which of the UL subframe sets the UL transmission subframe n+k belongs to, and adjust a TPC command accumulator value that corresponds to the determined UL subframe set to determine power of the UL transmission when transmitting in the UL transmission subframe, where n is an integer, and k is an integer greater than zero.

Abstract: A method implemented by a Wireless Transmit/Receive Unit (WTRU) includes receiving a DeModulation Interference Measurement (DM-IM) resource, determining an interference measurement based on the DM-IM resource, and demodulating a received signal based on the interference measurement. An interference is suppressed based on the interference measurement. At least one DM-IM resource is located in a Physical Resource Block (PRB). The DM-IM resource is located in a PRB allocated for the WTRU. The DM-IM resource is a plurality of DM-IM resources which form a DM-IM pattern, and the DM-IM pattern is located on a Physical Downlink Shared Channel (PDSCH) and/or an enhanced Physical Downlink Shared Channel (E-PDSCH) of at least one Long Term Evolution (LTE) subframe. The DM-IM resources are different for different Physical Resource Blocks (PRB) in the LTE subframe. The DM-IM is located in a Long Term Evolution (LTE) Resource Block (RB), and the DM-IM pattern is adjusted.

Abstract: Methods and devices for offloading and/or aggregation of resources to coordinate uplink transmissions when interacting with different schedulers are disclosed herein. A method in a WTRU includes functionality for coordinating with a different scheduler for each eNB associated with the WTRU's configuration. Disclosed methods include autonomous WTRU grant selection and power scaling, and dynamic prioritization of transmission and power scaling priority.
