Patent number: 9219591Abstract: 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.Type: GrantFiled: April 4, 2013Date of Patent: December 22, 2015Assignee: Nokia Solutions and Networks OyInventors: Xiangguang Che, Peng Chen, Frank Frederiksen, Troels Kolding

Patent number: 9048989Abstract: 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.Type: GrantFiled: September 9, 2013Date of Patent: June 2, 2015Assignee: WIRELESS FUTURE TECHNOLOGIES INC.Inventors: Erlin Zeng, Haiming Wang, Xiangguang Che, Chungyan Gao, Peng Chen, Jing Han, Bernhard Raaf

Publication number: 20090046649Abstract: For each of at least two ratios of downlink subframes exceeding uplink subframes in a frame is stored a pre-determined grouping of a plurality of downlink subframes that map to one uplink subframe. A frame is scheduled corresponding to one of the ratios. Scheduling grants are transmitted to user equipments UEs in at least some of the scheduled downlink subframes, wherein the number of scheduled downlink subframes is greater than the number of scheduled uplink subframes in the frame. The UEs receive their grant, map the downlink subframe in which the scheduling grant was received to an uplink subframe using the stored predetermined grouping for the ratio that corresponds to the frame in which the scheduling grant was received, and send their ACK/NACK for the grant in the mapped subframe. The network receives multiple ACKs/NACKs in a single uplink subframe and maps them, to the downlink subframes of the group.Type: ApplicationFiled: August 12, 2008Publication date: February 19, 2009Inventors: Chun Yan Gao, Yuan Zhu, Xiangguang Che
