Publication number: 20160191174Abstract: A method is proposed to enable a UE performing codeword level interference cancellation (CW-IC) to know whether an interfering transport block (TB) is a new transmission or retransmission. With this knowledge, the UE knows whether the soft channel bits stored in a soft buffer are to be discarded or combined with the soft channel bits newly obtained.Type: ApplicationFiled: December 28, 2015Publication date: June 30, 2016Inventors: Chien-Hwa Hwang, Yi-Ju Liao, Tze-Ping Low, Lung-Sheng Tsai

Publication number: 20160191225Abstract: Methods for rate matching with soft buffer size setting at the transmitter and soft channel bits storage at the receiver for superposition coding are proposed. In the superposition coding scheme, a transport block intended to one UE needs to be decoded by another UE's receiver. However, the soft buffer sizes per code block of the two receivers may not be the same since the size depends on the UE category. The base station can signal the soft buffer size used at the transmitter for rate matching to the UEs for superposition decoding. A UE stores information bits associated with an interfering signal in its soft buffers in accordance with the soft buffer size used at the transmitter for rate matching. As a result, the UE can decode and subtract the interfering signal from the desired signal for superposition coding.Type: ApplicationFiled: December 28, 2015Publication date: June 30, 2016Inventors: Chien-Hwa Hwang, Lung-Sheng Tsai, Yi-Ju Liao, Tze-Ping Low

Publication number: 20160192383Abstract: When the codeword level interference cancellation (CW-IC) is used at the receiver in conjunction with the superposition coding scheme at the transmitter, it is helpful if the soft buffer at the receiver is reserved not only for the desired transport blocks (TBs) but also for the interfering TBs handled by the CW-IC. In so doing, the soft channel bits of interfering TBs at multiple (re)transmissions can be combined to enhance the success rate of data decoding. A soft buffer partition method for the soft channel bits of the desired and interfering TBs in the superposition coding scheme is proposed. The proposed method has a full flexibility in adjusting the soft buffer sizes for the desired and interfering TBs.Type: ApplicationFiled: December 28, 2015Publication date: June 30, 2016Inventors: Chien-Hwa Hwang, Yi-Ju Liao, Tze-Ping Low, Lung-Sheng Tsai

Publication number: 20160100413Abstract: Signaling methods to support robust interference cancellation by obtaining information associated with interfering signals from the network side are provided. The target interference for cancellation is intra-cell interference from MU-MIMO or NOMA operation. A victim receiver receives both desired signal and intra-cell interfering signal. The network may assist the victim receiver by providing information related to the interfering signal. The computational complexity of the victim receiver in blindly detecting the interference signal characteristics is reduced, and the reliability of the signal detection is improved.Type: ApplicationFiled: September 29, 2015Publication date: April 7, 2016Inventors: Chien-Hwa Hwang, Pei-Kai Liao, Lung-Sheng Tsai

Publication number: 20150215103Abstract: A method of interference cancellation is proposed. A serving base station transmits a first configuration information to a UE, the first configuration information is related to a desired signal of a data transmission from a serving cell to the UE. The serving base station determines a second configuration information related to an interference signal of a data transmission from a neighboring cell to the UE. The second configuration information comprises a resource allocation type and a basic resource allocation unit of the interference signal. The serving base station transmits the second configuration information to the UE such that the UE can cancel the data transmission from the neighboring cell.Type: ApplicationFiled: January 28, 2015Publication date: July 30, 2015Inventors: Lung-Sheng Tsai, Xiangyang Zhuang

Publication number: 20150215061Abstract: A method of interference cancellation is proposed. A UE obtains configuration information of a data transmission from a neighboring cell via an interference channel in a mobile communication network. The UE receives radio signals on a set of data resource elements as determined based on the obtained configuration information. The UE then estimates the interference channel corresponding to the data transmission from the neighboring cell based on the received radio signals on the set of data resource elements. Finally, the UE cancels the data transmission from the neighboring cell based on the estimated interference channel.Type: ApplicationFiled: January 28, 2015Publication date: July 30, 2015Inventors: Lung-Sheng Tsai, Xiangyang Zhuang

Publication number: 20150146657Abstract: A method for a receiver to cancel or suppress co-channel interference with network assistance is provided. The method comprises deriving a first set of parameters related to interfering signals in a mobile communication network; receiving a second set of parameters related to the interfering signals from the network; and cancelling the contribution of interfering signals from the received signal based on the combination of the first set and second set of parameters. In one embodiment, scrambling rules and resource block allocation information are signaled to the victim UE to facilitate Codeword-Level Interference Cancellation (CWIC). While the scrambling rule for control channel is based on UE-specific identity, the scrambling rule for data channel is based on cell-specific identity or other network-configurable identity to facilitate CWIC. In addition, RA-allocation information are signaled to the victim UE in an efficient way.Type: ApplicationFiled: November 26, 2014Publication date: May 28, 2015Inventors: Lung-Sheng Tsai, Xiangyang Zhuang, Pei-Kai Liao

The method comprises deriving a first set of parameters related to interfering signals in a mobile communication network; receiving a second set of parameters related to the interfering signals from the network; and cancelling the contribution of interfering signals from the received signal based on the combination of the first set and second set of parameters. In one embodiment, the interfering signals comprise intra-cell interfering signals and/or inter-cell interfering signals. While inter-cell interference comes from neighboring cells, intra-cell interference comes from MU-MIMO transmission to other users in the same serving cell as the victim UE. In one example, the serving base station not only signals information to the victim UE for inter-cell interference, but also for intra-cell interference due to MU-MIMO transmission.Type: ApplicationFiled: November 26, 2014Publication date: May 28, 2015Inventors: Lung-Sheng Tsai, Xiangyang Zhuang, Pei-Kai Liao
