    摘要: Methods and systems for transmitting scheduling requests in an LTE Advanced system are disclosed. Scheduling requests may be superimposed on HARQ ACK/NACK by multiplying the HARQ ACK/NACK by a value. Alternatively, scheduling requests may be channel-coded and multiplexed with other uplink control information. Scheduling requests can also be superimposed on reference signals by multiplying a reference signal by a value or by modulating a reference signal with a cyclic shift. Scheduling requests may also be jointly coded with HARQ ACK/NACK prior to transmission. Alternatively, ACK/NACK responses may be transmitted on assigned ACK/NACK PUCCH resources for a negative scheduling request transmission and on assigned scheduling request PUCCH resources for a positive scheduling request. Various collision handling mechanisms are also disclosed.

    摘要: Methods and systems for sending and receiving an enhanced downlink control channel are disclosed. The method may include receiving control channel information via an enhanced control channel. The method may also include using the control channel information to receive a shared channel. The method may include detecting the presence of the enhanced control channel in a given subframe. The enhanced control channel may be transmitted over multiple antenna ports. For example, code divisional multiplexing and de-multiplexing and the use of common and UE-specific reference signals may be utilized. New control channel elements may be defined, and enhanced control channel state information (CSI) feedback may be utilized. The presence or absence of legacy control channels may affect the demodulation and or decoding methods. The method may be implemented at a WTRU.

    摘要: Techniques for configuring and switching a resource assignment mode for a plurality of component carriers are disclosed. A wireless transmit/receive unit (WTRU) has a capability of supporting multiple resource assignment modes such that a resource assignment mode is configured for a plurality of component carriers that are allocated for the WTRU, and the WTRU attempts to decode a control channel based on the configured resource assignment mode. The resource assignment mode may be configured for the WTRU via higher layer signaling. The resource assignment mode may be specific to the WTRU, or specific to a component carrier or a group of component carriers. The resource assignment mode may be configured separately for a downlink component carrier and an uplink component carrier. The resource assignment mode includes a separate assignment mode with component carrier indication, a separate assignment mode without component carrier indication, or a joint assignment mode.
