CARRIER AGGREGATION OF CARRIERS WITH SUBFRAME RESTRICTIONS
First Claim
1. A wireless transmit/receive unit (WTRU) comprising:
- a processor configured to;
communicate with at least a first serving cell and a second serving cell via at least one interface, wherein communications with the first serving cell are performed according to a first subframe partitioning configuration and communications performed with the second serving cell are performed according to a second subframe partitioning configuration;
determine that a transmission direction associated with a first subframe of the first subframe partitioning configuration is a different transmission direction than a transmission direction associated with a corresponding subframe of the second subframe partitioning configuration; and
apply the first subframe partitioning configuration during at least the first subframe based on the first serving cell being a primary serving cell (PCell) and the second serving cell being a secondary cell (SCell).

Abstract
Embodiments contemplate enabling relay node uplink control information transmission on an interface between a relay node and a donor eNodeB (DeNB) in one or more subframes. Embodiments contemplate techniques to avoid restrictions on uplink transmissions on a cell (perhaps due to subframe configuration), such as on a primary cell, where the restrictions may make relay node uplink control information transmission difficult (if not impossible) on the interface between a relay node and a donor eNodeB (DeNB). Embodiments also contemplate that resources on the interface between the relay node and the donor eNodeB may be scheduled across one or more component carriers or serving cells.

21. A node comprising:
-
a processor configured to; send a first subframe partitioning configuration and a second subframe partitioning configuration via a radio resource control (RRC) signal to a wireless transmit/receive unit (WTRU), wherein communications with a first serving cell are performed according to the first subframe partitioning configuration and communications performed with a second serving cell are performed according to the second subframe partitioning configuration, and wherein a transmission direction associated with a first subframe of the first subframe partitioning configuration is a different transmission direction than a transmission direction associated with a corresponding subframe of the second subframe partitioning configuration; and communicate with the WTRU via the first serving cell and the second serving cell by applying the first subframe partitioning configuration during at least the first subframe based on the first serving cell being a primary serving cell (PCell) and the second serving cell being a secondary serving cell (SCell). - View Dependent Claims (22, 23, 24, 25, 26)
