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.

(canceled)
An apparatus comprising:
- processing circuitry including logic to establish a slot configuration for receipt of evolved node-B (eNB) to relay node (RN) transmissions, the slot configuration defining starting and ending OFDM symbols of a subframe;
- and
- a radio frequency (RF) interface to
- receive eNB-to-RN transmissions in a subset of OFDM symbols in a slot based on the slot configuration;
- and
- receive control channel information in accordance with the established slot configuration for the eNB-to-RN transmissions.
A computer-readable medium comprising instructions that, when executed on a device, cause the device to:
- establish a slot configuration for receipt of evolved node-B (eNB) to relay node (RN) transmissions, the slot configuration defining starting and ending OFDM symbols of a subframe;
- receive eNB-to-RN transmissions in a subset of OFDM symbols in a slot based on the slot configuration;
- and
- receive control channel information in accordance with the established slot configuration for the eNB-to-RN transmissions.
A method for relay node operation performed by a relay node (RN) in which evolved 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:
- establishing a slot configuration for receipt of eNB-to-RN transmissions, the slot configuration defining starting and ending OFDM symbols of a subframe;
- receiving eNB-to-RN transmissions in a subset of OFDM symbols in a slot based on the slot configuration;
- and
- receiving control channel information in accordance with the established slot configuration for the eNB-to-RN transmissions.
