Abstract

Aspects are disclosed for operating a relay via an MBSFN-based backhaul link. Control resources are allocated, which include a first set of control resources and a second set of control resources. For some embodiments, a portion of the first set of control resources is concatenated with a portion of the second set of control resources to form a concatenation of resources whereas, in other embodiments, an indication scheme is implemented to provide an indication of a first or second allocation size respectively associated with the first and second set of control resources. At least one control signal is then transmitted which includes at least one of the concatenation or the indication. Other disclosed embodiments are directed towards configuring a user equipment to decode a control signal generated according to the aspects disclosed herein.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application Serial No. 61 / 181,587, filed May 27, 2009, entitled "Enhanced MBSFN Based Backhaul Link for Relaying Operation in LTE-A." The above application is incorporated herein by reference in its entirety. technical field [0003] The following description relates generally to wireless communications, and more specifically to methods and apparatus that facilitate operation of a relay station via a multimedia broadcast single frequency network based backhaul link. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, data, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth and transmit power). Examples of these multiple access systems include Code Divis...
