    摘要: Methods for signaling multi-user multiple-input multiple output (MU-MIMO) parameters for Evolved-UTRA (E-UTRA) are disclosed. Example signaling format methods are presented that allow use of distributed virtual resource blocks (DVRB) or support of four wireless transmit/receive units (WTRUs) but maintaining a predetermined signal format size. A signaling format is also presented that signals transmission precoding matrix indexes used by all co-scheduled WTRUs.

    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.
