    Abstract: A method for transmitting control information related to a hybrid automatic repeat request (HARQ) process operation using a frequency division duplex (FDD) frame structure by a base station (BS) in a wireless communication system; the BS therefore; a method for receiving control information related to a HARQ process operation using a FDD frame structure by an RN; and the RN therefore are discussed. The method for transmitting control information according to one embodiment includes transmitting information related to a number of HARQ processes. The HARQ processes are sequentially assigned to subframes configured for the RN-to-the BS transmission. If a subframe configured for the BS-to-the RN transmission is a subframe n, a subframe configured for the RN-to-the BS transmission is a subframe n+4. The method further includes transmitting a HARQ ACK/NACK signal for uplink data through a corresponding subframe based on the number of HARQ processes.

    Abstract: In a communication system (100) where a wireless relay node (RN) (114) relays data packets between a Node B (112) and a user equipment (UE) (102), the RN receives (608) a data packet from the Node B via a first wireless link (115), conveys (614) the received data packet to the UE via a second wireless link (120), determines (616) whether the UE is likely to handoff, and in response to determining that the UE is likely to handoff, delays conveying (620, 622) an acknowledgment of the data packet to the Node B until an acknowledgment has been received from the UE. In another embodiment, the RN may use a status report (720) to inform the Node B of data packets that have not been transmitted to the UE or that have been transmitted to the UE but for which an acknowledgement has not been received from the UE.

    Abstract: Techniques for inter-cell interference cancellation are disclosed. At each transmitter, the data (message) may split into two or more layers, (e.g., common and private parts), and may be encoded in different rates, allocated with different powers, possibly beamformed using different precoders, and transmitted through the same physical channels. The common part is to be decoded at both the intended and unintended users, while the private part is to be decoded at the intended user.

    Abstract: Methods, systems and apparatuses are provided for transmitting and receiving space-time block coded data in a wireless communications system with co-operative relays. A source node transmits RF signals representing first and second sets of data symbols in respective first and second channels (in time frequency code or any combination) of a wireless communications system, the first and second sets of data symbols being for transmission from separate antennas respectively according to a space-time block code. A relay node receives the RF signals representing the first set of data symbols in the first channel and transmits RF signals representing the first set of data symbols in the second channel. A destination node received the RF signals representing the second set of data symbols from the source node and the RF signals representing the first set of data symbols from the relay node. This enables decoding of the received RF signals representing the first and second sets of data symbols according to the space-time block code.
