摘要： Reference signals configured for use with extension carriers and/or carrier segments are described. Reference signals for extension carriers and/or carrier segments may include demodulation reference signals (e.g., user equipment-specific reference signals), cell-specific reference signals, and channel-state information reference signals. Methods, systems and apparatuses for configuring extension carriers and/or carrier segments with one or more of the reference signals (e.g., positioning one or more reference signal symbols in extension carriers and/or carrier segments) are described.

摘要： Methods and systems for transmitting uplink control information and feedback are disclosed for carrier aggregation systems. A user equipment device may be configured to transmit uplink control information and other feedback for several downlink component carriers using one or more uplink component carriers. The user equipment device may be configured to transmit such data using a physical uplink control channel rather than a physical uplink shared channel. The user equipment device may be configured to determine the uplink control information and feedback data that is to be transmitted, the physical uplink control channel resources to be used to transmit the uplink control information and feedback data, and how the uplink control information and feedback data may be transmitted over the physical uplink control channel.

摘要： A wireless transmit/receiver unit (WTRU) is configured to receive sounding reference signal (SRS) configuration information. The SRS configuration information indicates a plurality of SRS configurations and indicates antenna transmission information. The WTRU is configured to receive SRS trigger information. The SRS trigger information comprises an indication to trigger transmission of one of the plurality of SRS configurations. The WTRU is configured to transmit a plurality of SRS associated with the indication in the SRS trigger information and based on the SRS configuration information. At least a first SRS of the plurality of SRS is transmitted over a first antenna port in a first symbol and at least a second SRS of the plurality of SRS is transmitted over a second antenna port in a second symbol.

摘要： A wireless transmit/receive unit (WTRU) is configured to receive a WTRU-specific configuration of WTRU-specific sounding reference signal (SRS) subframes for performing SRS transmissions. The WTRU is configured to receive a trigger in a subframe to transmit a first SRS. The WTRU is configured to select a first subframe. The WTRU is configured to determine that a maximum power would be exceeded in a symbol in the selected first subframe. The WTRU is configured to, on a condition that transmission of at least one other SRS would at least partially overlap in the symbol in the selected first subframe, scale transmission powers of the first SRS and the at least one other SRS equally to comply with the maximum power. The WTRU is configured to transmit, in accordance with the scaled transmission powers, the first SRS in the selected subframe and the at least one other SRS.

摘要： ePDCCH may be provided. For example, a WTRU may receive a configuration for monitoring an ePDCCH resource. Based on the configuration, the WTRU may be configured to monitor and may monitor the ePDCCH resource on a particular subframe. Additionally, a WTRU may derive an aggregation level for a subframe associated with an aggregation level number NAL. The WTRU may transmit or monitor an ePDCCH using the aggregation level associated with the NAL for the subframe. A WTRU may also receive a reference signal. The WTRU may then determine the type of reference signal received. The WTRU may perform a demodulation of the PDSCH or ePDCCH using a demodulation timing based on the determined type. The ePDCCH or PDSCH may also be monitored or received by identifying a demodulation reference timing implicitly based on a location of one or more ePDCCH resources where the WTRU may receive DCI.

摘要： A method and apparatus for determining uplink power in a wireless transmit receive unit (WTRU). The WTRU operates in a carrier aggregated system. The WTRU is configured to receive a plurality of uplink power parameters indexed to one of a plurality of uplink carriers and receive a transmit power control command indexed to the one of the plurality of uplink carriers. The WTRU is configured to determine a pathloss of the one of the plurality of uplink carriers and determine a transmit power for the one of the plurality of uplink carriers based on the plurality of power parameters, the transmit power control command, and the pathloss.
