The wireless transmitting apparatus obtains a data stream and allocates the data stream to a first sub-carrier set. Each of the first sub-carrier set and a second sub-carrier set has sub-carriers with opposite frequencies to each other, respectively. The second sub-carrier is emptied or allocated according the data stream allocated to the first sub-carrier set. The data stream is converted into an OFDM signal transmitted through a transmitting module. The wireless receiving apparatus includes a single branch receiver for receiving a radio frequency (RF) signal and outputting a baseband signal. Subsequently, the data stream is restored from the baseband signal.Type: GrantFiled: October 27, 2015Date of Patent: March 28, 2017Assignee: Acer IncorporatedInventors: Tsung-Yu Tsai, You-Hsien Lin, Hsuan-Li Lin, Terng-Yin Hsu

Patent number: 9608780Abstract: Techniques for transmitting data with transmit diversity for single-carrier frequency division multiple access (SC-FDMA) are described. In one design, a transmitter (e.g., a UE) may form a first symbol vector including first and second modulation symbol sequences. The transmitter may also form a second symbol vector including third and fourth modulation symbol sequences, which may be generated based on the second and first modulation symbol sequences, respectively. Each symbol vector may further include a cyclic prefix and possibly a cyclic postfix for each modulation symbol sequence. The transmitter may generate a first SC-FDMA symbol based on the first symbol vector and a second SC-FDMA symbol based on the second symbol vector. The transmitter may transmit the first and second SC-FDMA symbols from two transmit antennas in a single SC-FDMA symbol period to achieve transmit diversity.Type: GrantFiled: September 22, 2009Date of Patent: March 28, 2017Assignee: QUALCOMM IncorporatedInventors: Xiliang Luo, Peter Gaal, Juan Montojo, Wanshi Chen

Patent number: 9608784Abstract: A base station communicating data to/from plural mobile terminals over plural OFDM sub-carriers within a coverage area. The base station allocates transmission resources provided by a first group of the plural OFDM sub-carriers within a first frequency band to mobile terminals of a first type and allocates transmission resources provided by a second group of the plural OFDM sub-carriers within a second frequency band to terminals of a second type, the second group being smaller than the first group and the second frequency band selected from within the first frequency band. The base station transmits control information including resource allocation information for terminals of the first type over a first bandwidth corresponding to the combined first and second groups of OFDM sub-carriers and transmits control information including resource allocation information for terminals of the second type over a second bandwidth corresponding to the second group of OFDM sub-carriers.Type: GrantFiled: February 1, 2012Date of Patent: March 28, 2017Assignee: SCA IPLA HOLDINGS INCInventors: Darren McNamara, Andrew Lillie, Peter Darwood, Martin Beale

Patent number: 9608785Abstract: The present invention relates to a wireless communication system, and more specifically, to a method and an apparatus for estimating a channel using a reference signal. According to one embodiment of the present invention, a method in which a terminal estimates a channel in a wireless communication system may comprise the steps of: receiving a cell-specific reference signal (CRS) and a channel state information-reference signal (CSI-RS) from a base station; generating CSI of a channel estimated using the CRS on the basis of a channel estimated using the CSI-RS and a mapping relationship between the CRS port and the CSI-RS port; reporting the generated CSI to the base station; and demodulating data on the basis of the channel estimated using the CRS.Type: GrantFiled: January 11, 2013Date of Patent: March 28, 2017Assignee: LG ELECTRONICS INC.Inventors: Hyungtae Kim, Jonghyun Park, Hanbyul Seo, Kijun Kim

Patent number: 9608787Abstract: A method and a device for notifying reference signal configuration information are disclosed. Channel state information-reference signal (CSI-RS) configuration information is coded, to obtain a CSI-RS configuration information code. A mapping relation between the CSI-RS configuration information code and the CSI-RS configuration information is stored. A CSI-RS configuration information code corresponding to CSI-RS configuration information to be notified is searched in the stored mapping relation between the CSI-RS configuration information code and the CSI-RS configuration information. The searched CSI-RS configuration information code is sent to a user equipment (UE), so that the UE determines CSI-RS configuration information according to the received CSI-RS configuration information code and the mapping relation between the CSI-RS configuration information code and the CSI-RS configuration information.Type: GrantFiled: August 23, 2016Date of Patent: March 28, 2017Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: David Mazzarese, Yuan Xia, Liang Xia
