In accordance with an example embodiment of the present invention, a method comprises allocating a control channel resource in a wireless relay transmission frame on a wireless relay link; generating a control signaling based on at least one of a resource allocation scheme, a status of the wireless relay link and a traffic condition of the wireless relay link; mapping the control signaling to the allocated control channel resource via at least one of a time-first mapping, a frequency-first mapping, and a multiplexing mapping; and transmitting the control signaling in the allocated control channel resource on the wireless relay link to at least one associated relay node.

Control signaling for wireless communication

An apparatus and method for initialization and mapping of reference signals in a communication system. In one embodiment, the apparatus includes a processor and memory including computer program code. The memory and the computer program code are configured to, with the processor, cause the apparatus to generate a reference signal employable with a plurality of physical resource blocks corresponding to a bandwidth of a communication system, and allocate resource elements of an assigned physical resource block from the plurality of physical resource blocks to a user equipment. The memory and the computer program code are further configured to, with the processor, cause the apparatus to generate a dedicated reference signal for the user equipment by allocating elements of the reference signal in accordance with allocated resource elements of the assigned physical resource block.

An approach is provided for acknowledgement bundling. Dynamically scheduling of one or more of subframes per bundling window is performed by reusing an assignment index field (e.g., downlink assignment index (DAI) field). The assignment index field has a value greater than or equal to number of previously assigned subframes within the bundling window. The bundling window defines a group of subframes for common acknowledgement.

Method and apparatus for providing acknowledgement bundling

Using an allocated control channel resource in a relay transmission frame, with an identified starting point, in a semi-static allocation scheme is disclosed. The control signaling may be mapped to the allocated control channel resource using different mapping schemes. Also disclosed is decoding a control channel element from a relay transmission frame received via a wireless relay link. The control channel resource associated with the relay transmission frame may be allocated in a semi-static allocation scheme. A starting indicator may be extracted from the decoded control channel element. A part of control signaling may be extracted from the decoded control channel element using the extracted starting indicator.

A method, mobile device, network device, and software product are for forming a time division duplex frame structure, including a downlink pilot timeslot within an initial data timeslot of the frame structure, and also including an uplink pilot timeslot in a further data timeslot of the frame structure. A guard period is located between the initial data timeslot and the further data timeslot.
