Patent number: 10615825Abstract: Methods, systems, and devices for wireless communication are described. In a new radio (NR) system, a wireless device may identify a candidate codeword for a channel employing polar coding. The wireless device may perform a decoding operation on the candidate codeword to determine candidate decoding paths corresponding to encoded information bits. The decoding operation may include multiple decoding path candidates, each of which is associated with a path metric. The wireless device may evaluate a spread metric to determine if a decoding hypothesis is incorrect or if the received codeword is too corrupted for decoding. The spread metric may be based on the path metrics of the decoding paths or soft metrics of the decoding paths determined based on a subset of bit channels of the polar code. The wireless device may normalize the spread metric to compensate for signal-to-noise ratio (SNR) variation.Type: GrantFiled: May 2, 2018Date of Patent: April 7, 2020Assignee: QUALCOMM IncorporatedInventors: Gabi Sarkis, Jing Jiang, Jamie Menjay Lin, Yang Yang

Patent number: 10601447Abstract: Methods, systems, and devices for wireless communication are described. In a new radio (NR) system, a wireless device may encode control information into a codeword using a polar code. The device may prioritize certain information within the codeword due to the time criticalness of that information for processing at a receiving device. For example, information related to frequency allocation may be encoded such that the receiving device may decode the frequency allocation information early in the decoding process. The device may include partial parity checks throughout the codeword, so that the receiving device may test whether the decoded bits for the prioritized information pass a parity check, and may then send these decoded bits for processing before completing decoding of the codeword. In some cases, the device may encode the information to be transmitted using multiple evenized codewords, or using a single consolidated codeword.Type: GrantFiled: May 10, 2018Date of Patent: March 24, 2020Assignee: QUALCOMM IncorporatedInventors: Jamie Menjay Lin, Krishna Kiran Mukkavilli, Gabi Sarkis, Peter Pui Lok Ang

Patent number: 10601450Abstract: Techniques are described to address run-time issues and other considerations of data structure reorganization operations executed while decoding a polar code. A receiving entity (e.g., a user equipment or a base station) partitions an array, or other data structure, into sections. The array is used during a list decoding operation of a polar code. As the array is populated with path elements for candidate paths, each section is organized and a permutation pattern is calculated for each section. Upon identifying a section reorganization event, the array or subsections of the array are reorganized according the permutation patterns determined for each section.Type: GrantFiled: March 27, 2018Date of Patent: March 24, 2020Assignee: QUALCOMM IncorporatedInventors: Jamie Menjay Lin, Yang Yang, Gabi Sarkis, Rotem Cooper, John Edward Smee

Patent number: 10595302Abstract: An apparatus may utilize an air interface to transmit and/or receive a subframe having a data portion and a control channel that is at least partly embedded within the data portion. The control channel may include one or more pilot tones. The control channel may include an override indicator. The override indicator may indicate that data previously scheduled for transmission in the subframe is overridden by other data having a higher priority. The override indicator may indicate a puncturing of resource elements in the data portion of the subframe to include other data having a priority higher than data previously scheduled for transmission in the subframe. The control channel may include a modulation indicator when the subframe is included in a multi-user multiple-input multiple-output (MU-MIMO) transmission. The modulation indicator may indicate information corresponding to a modulation of another apparatus that is included in the MU-MIMO transmission.Type: GrantFiled: November 25, 2015Date of Patent: March 17, 2020Assignee: QUALCOMM IncorporatedInventors: Krishna Kiran Mukkavilli, Jing Jiang, Tingfang Ji, Jamie Menjay Lin, Joseph Binamira Soriaga, John Edward Smee

Patent number: 10547402Abstract: Methods, systems, and devices for wireless communication are described. A wireless communication network may support mission critical (MiCr) communications and mobile broadband (MBB) communications with hybrid multiplexing (e.g., time division multiplexing (TDM) and frequency division multiplexing (FDM)). A base station may identify a first set of resources allocated for MiCr communications and a second set of resources allocated for MBB communications. The first and second set of resources may be multiplexed in the frequency domain, and the base station may transmit MiCr information over the first set of resources under normal data traffic conditions. As data traffic or other conditions associated with MiCr communications change, the base station may schedule MiCr transmissions on the second set of resources allocated for MBB communications, by puncturing the second set of resources for the MiCr communications.Type: GrantFiled: June 16, 2017Date of Patent: January 28, 2020Assignee: QUALCOMM IncorporatedInventors: Chong Li, Hao Xu, Jamie Menjay Lin, Chih Ping Li, Jing Jiang, Tingfang Ji

Patent number: 10498503Abstract: Multicasting resource allocation information per aggregation level is enabled. A device allocates resources to UEs according to aggregation level. At each level, a control message includes a bitmap, where each bit corresponds to a different resource, an array, and an ID field for dynamic mapping to the bitmap. The placement order value of an ID in the field is stored at locations in the array. The index value for those locations in the array identifies which asserted bits in the bitmap correspond to the resource allocation for a UE at the level. The control message is multicast to the UEs specified at the aggregation level. The bitmap may have the same length at each level, or have reducing length at lower levels with the removal of bits already asserted at higher levels. The UE reconstructs the bitmap from the higher level bitmaps and the bitmap for the current level.Type: GrantFiled: September 15, 2016Date of Patent: December 3, 2019Assignee: QUALCOMM IncorporatedInventors: Saurabha Tavildar, Jamie Menjay Lin, Jing Jiang, Tingfang Ji

Patent number: 10484972Abstract: Various techniques provide for identifying and transmitting a first transmission to a UE in a first transmission time interval (TTI), and puncturing a portion of the first transmission with a higher priority second transmission that has a shorter TTI than the first TTI. The punctured portion of the first transmission may then be transmitted in a subsequent portion of the first TTI, concurrently with an originally allocated portion of the first transmission for that subsequent portion of the TTI. A UE may identify the punctured portion of the first transmission, and identify that the punctured portion of the first transmission is being transmitted in the subsequent portion of the first TTI. The UE may decode the received transmissions and merge the punctured portion with other, non-punctured, portions of the first transmission.Type: GrantFiled: October 19, 2017Date of Patent: November 19, 2019Assignee: QUALCOMM IncorporatedInventors: Jamie Menjay Lin, Hao Xu, Chong Li, Chih-Ping Li, Jing Jiang, Tingfang Ji

Patent number: 10476998Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for increasing decoding performance and/or reducing decoding complexity. A transmitter may divide data of a codeword into two or more sections and then calculate redundancy check information (e.g., a cyclic redundancy check or a parity check) for each section and attach the redundancy check information to the codeword. A decoder of a receiver may decode each section of the codeword and check the decoding against the corresponding redundancy check information. If decoding of a section fails, the decoder may use information regarding section(s) that the decoder successfully decoded in re-attempting to decode the section(s) that failed decoding. In addition, the decoder may use a different technique to decode the section(s) that failed decoding. If the decoder is still unsuccessful in decoding the section(s), then the receiver may request retransmission of the failed section(s) or of the entire codeword.Type: GrantFiled: June 9, 2017Date of Patent: November 12, 2019Assignee: QUALCOMM IncorporatedInventors: Jamie Menjay Lin, Yang Yang, Joseph Binamira Soriaga

Publication number: 20190312671Abstract: Methods, systems, and devices for wireless communications are described. In accordance with the described techniques, communicating devices (e.g., an encoder and decoder) may apply an orthogonal cover code to a polar codeword to reduce cross-correlation between different codewords. For example, such techniques may reduce power consumption at a decoding device by providing for earlier decoding termination (e.g., as a result of the reduced cross-correlation). Techniques for generating the cover codes (e.g., on a per-aggregation level basis) and applying the cover codes (e.g., within a search space) are described. Additionally or alternatively, the described techniques may relate to seeding of reference signals used to support decoding of the codewords. Improved orthogonality between reference signal seeds may further suppress codeword recipient ambiguity.Type: ApplicationFiled: April 5, 2019Publication date: October 10, 2019Inventors: Jamie Menjay Lin, Siddhartha Mallik, Tamer Kadous
