1. A method for relay node operation performed by a relay node (RN) in which enhanced node-B (eNB) to RN and RN to user-equipment (UE) transmissions are time multiplexed using time-frequency resources set aside by an eNB, the method comprising:
- determining a slot configuration for receipt of eNB to RN transmissions, the slot configuration defining starting and ending orthogonal frequency division multiplexing (OFDM) symbols of a subframe;
receiving eNB to RN transmissions restricted to a subset of OFDM symbols in a slot based on the slot configuration; and
receiving a control channel in accordance with one of the slot configurations for the eNB to RN transmissions.

Abstract
A frame structure for support of large delay spread deployment scenarios (e.g., cellular system operation in large cell sizes or low frequency bands) is generally presented. In this regard a method is introduced comprising partitioning a radio frame into a plurality of equal-sized (or non-equal-sized) sub-frames to simplify system implementation. Other embodiments are also disclosed and claimed.
