Patent number: 9338763Abstract: Systems and methodologies are described herein that facilitate processing and pruning of blind decoding results (e.g., associated with grant signaling) within a wireless communication environment. As described herein, blind decoding results associated with grant signaling and/or other suitable signaling can be pruned in various manners, thereby reducing false alarm probabilities associated with such results. For example, techniques are provided herein for constraining respective decoding candidates to possible radio network temporary identifier (RNTI) values, performing validity checking on payload of respective decoding candidates, and selecting a most likely decoding candidate from a previously pruned set of candidates. Further, techniques are described herein for generating filler bits (e.g., padding bits, reserved bits, etc.) in a grant message according to a predefined pattern, thereby enabling checking of such bits to further reduce false alarm rates.Type: GrantFiled: April 1, 2013Date of Patent: May 10, 2016Assignee: QUALCOMM IncorporatedInventors: Kibeom Seong, Tao Luo

Patent number: 9232462Abstract: Methods and apparatus for providing cross-cell signaling and/or coordination for interference mitigation in wireless communication networks are described. In one aspect, a UE associated with a serving eNB may receive control signaling from another non-serving eNB in a different cell. The control signaling may be consistent with a characteristic of the serving eNB and associated cell. In another aspect, multiple eNBs may coordinate transmission of DL resources to minimize collisions of control signaling resources.Type: GrantFiled: October 14, 2010Date of Patent: January 5, 2016Assignee: QUALCOMM IncorporatedInventors: Tao Luo, Xiaoxia Zhang, Kibeom Seong, Ke Liu, Taesang Yoo

Patent number: 9144037Abstract: Systems and methodologies are described that facilitate controlling interference in a heterogeneous wireless communication environment. A Physical Broadcast Channel (PBCH) transmission from an interfering base station can be punctured based upon a puncturing pattern as a function of a cell identifier (ID) and a transmit time. Puncturing can be effectuated by applying power control. Thus, a punctured symbol or subframe can have a reduced transmit power or a transmit power set to zero. Further, the puncturing pattern can be defined on a subframe basis or on a symbol basis.Type: GrantFiled: August 9, 2010Date of Patent: September 22, 2015Assignee: QUALCOMM IncorporatedInventors: Kibeom Seong, Tao Luo, Taesang Yoo, Xiaoxia Zhang, Dung Ngoc Doan

Patent number: 9042240Abstract: Techniques for reliable channel decoding in a wireless network are provided. In one aspect, a wireless device receives system information over a physical broadcast channel of a downlink transmission. The wireless device decodes the physical broadcast channel of a current radio frame using a plurality of hypotheses until the decoding passes a cyclic redundancy check. Thereafter, the wireless device compares system information from the current radio frame with information obtained from a previous radio frame. The information from the previous radio frame may include one or more network parameters which may be stored in a memory of the wireless device. In some aspects, the comparison may be performed over a plurality of radio frames. Based at least in part on a result of the comparing, the wireless device may selectively reject system information from one or more of the radio frames.Type: GrantFiled: July 28, 2010Date of Patent: May 26, 2015Assignee: QUALCOMM IncorporatedInventors: Tao Luo, Taesang Yoo, Kibeom Seong

Patent number: 8848603Abstract: Systems and methodologies are described that facilitate precoding signals transmitted over downlink control channels to provide transmit diversity. A dedicated reference signal (DRS) related to a wireless device can additionally be precoded such that the wireless device can determine a precoder or related parameters based at least in part on performing a channel estimate for the precoded DRS signal. The wireless device can utilize the determined precoder or related parameters to decode precoded signals received over downlink control channel resources. Additionally or alternatively, an access point can signal a sequence of precoders to the wireless device. The access point can cycle through the sequence of precoders to precode signals for transmission over downlink control channel resources, and the wireless device can decode the signals based at least in part on similarly cycling through the precoders for received signals.Type: GrantFiled: June 16, 2010Date of Patent: September 30, 2014Assignee: QUALCOMM IncorporatedInventors: Tao Luo, Dung Ngoc Doan, Taesang Yoo, Xiaoxia Zhang, Kibeom Seong

Patent number: 8638728Abstract: Providing for modified rate-matching of modulated data to convey mobile network system information is described herein. By way of example, a rate-matching state, such as a data offset, can be introduced into a coded data stream that is modulated to resources of a wireless signal. The state can further be correlated to a state of the network system, such as transmit antenna configuration. Terminals receiving the wireless signal can analyze the signal to identify the rate-matching state and obtain the correlated network system state. Components of the terminal can then be configured according to the particular network system state, resulting in improving access point detection, and in some cases improved channel throughput and reliability.Type: GrantFiled: September 3, 2008Date of Patent: January 28, 2014Assignee: QUALCOMM IncorporatedInventors: Tao Luo, Xiaoxia Zhang, Kibeom Seong

Patent number: 8509291Abstract: In a wireless communication system, SFBC-based (Space-Frequency Block-Code) transmission diversity schemes provide enhancement for multiple antennas, such as the illustrative four, in order to achieve better performance than SFBC-FSTD (SFBC-Frequency Switching Transmit Diversity) alone. SFBC-PFSTD (Precoded Frequency Switching Transmit), which is multiplying a precoding matrix to the SFBC-FSTD signals, opens up the possibility of utilizing the pilot tones in synchronization channels (SSC and/or PSC) to enhance the channel estimation performance for antenna 2 and 3 that have only the half as many pilot tones as antenna 0 and 1. Further improvements are disclosed for use of Frequency Time Switching Transmit Diversity (FTSTD) and Precoding Vector Switch.Type: GrantFiled: February 4, 2009Date of Patent: August 13, 2013Assignee: QUALCOMM IncorporatedInventors: Kibeom Seong, Tao Luo

Patent number: 8467480Abstract: Decision metrics used to decode wireless communication payloads are combined for successive frames to improve decoding of the later received frames. A bitwise payload difference between successive frames is encoded in the same manner the payloads are encoded. Decision metrics determined for the earlier received frame are combined with the encoded payload difference to generate adjusted decision metrics. The adjusted decision metrics are combined with decision metrics determined for the later received frame. The combined decision metrics are decoded to generate a payload for the later received frame. If the decoding is not successful the combined decision metrics are carried forward and the process is repeated based on the payload difference between the following frames.Type: GrantFiled: September 9, 2010Date of Patent: June 18, 2013Assignee: QUALCOMM IncorporatedInventors: Ke Liu, Kibeom Seong, Tao Luo, Yongbin Wei

Publication number: 20110182385Abstract: Reliability metric(s), based on output of a decoder module, associated with each possible hypothesis associated with blind decoding are provided that aids a pruning process by rejecting unreliable CRC-passed hypotheses. In an aspect, a downlink control channel carries scheduling assignments and other control information. As location, size, and CRC masking associated with downlink control information are not known to a receiver, blind decoding over possible hypotheses may be performed. The complex structure of the downlink control channel blind decoding results in increasing false alarm(s). Intelligent rules for pruning the decoding results are employed so that unreliable CRC-passed hypotheses are rejected as a function of respective reliability metric.Type: ApplicationFiled: July 29, 2010Publication date: July 28, 2011Applicant: QUALCOMM INCORPORATEDInventors: Dung Ngoc Doan, Kibeom Seong, Hossein Bagheri
