Patent number: 11190975Abstract: Methods, systems, and devices for wireless communication are described that provide for generation of an encoded transport block (TB) that includes a number of systematic code blocks (CBs) and a number of parity CBs. The systematic CBs may be transmitted to a receiver, and the receiver may attempt to decode the systematic CBs. In some cases, one or more parity CBs may be transmitted with the systematic CBs, and the systematic CBs may be successfully decoded even in the event that one or more of the systematic CBs are not successfully received. In some cases, a receiver may provide feedback that requests that additional CBs be transmitted to decode the systematic CBs that were received, and it is not necessary to retransmit the missing systematic CBs. In some cases, a quantized value of a number of additional CBs needed to decode the TB may be transmitted.Type: GrantFiled: September 22, 2017Date of Patent: November 30, 2021Assignee: QUALCOMM IncorporatedInventors: Jing Jiang, Seyedkianoush Hosseini, Huang Lou, Joseph Binamira Soriaga, Hari Sankar

Patent number: 11063613Abstract: Techniques are described herein to terminate a list decoding operation before its completion based on performing one or more error check processes. A transmitted codeword encoded using a polar code may include one or more error check vectors interspersed with one or more information vectors. Upon receiving the codeword, a decoder may perform a list decoding operation on the received codeword. Upon decoding one of the error check vectors, the decoder may determine whether at least one candidate path used in the successive cancellation list decoding operation passes an error check process based on the error check vector. If no candidate paths satisfy the error check process, the decoder may terminate the list decoding operation. In some examples, the decoder may recheck whether candidate paths satisfy the error check operation at intermediate positions between error check vectors. Such rechecking may occur while decoding information vectors.Type: GrantFiled: May 15, 2017Date of Patent: July 13, 2021Assignee: QUALCOMM INCORPORATEDInventors: Gabi Sarkis, Hari Sankar, Gaojin Wu, Changlong Xu, Jing Jiang, Huang Lou

Patent number: 10686469Abstract: Size ambiguity and false alarm rate reduction for polar codes. A user equipment (UE) may determine a decoding candidate bit sequence for a polar-encoded codeword having a codeword size based on a decoding hypothesis for control information having a particular bit length of multiple different bit lengths for the codeword size. The UE may calculate an error detection code (EDC) value for a payload portion of the decoding candidate bit sequence using an EDC algorithm, and may initialize an EDC variable state with at least one non-zero bit value. Scrambling or interleaving of bits may also be performed prior to, or after, polar encoding and may depend on the bit length. In examples, information bits may be bit-reversed prior to generating an EDC value. In examples, the encoded bits may include multiple EDC values to assist the UE in performing early termination and to reduce a false alarm rate.Type: GrantFiled: April 13, 2018Date of Patent: June 16, 2020Assignee: QUALCOMM IncorporatedInventors: Huang Lou, Jing Jiang, Enoch Shiao-Kuang Lu, Gabi Sarkis, Yang Yang, Hari Sankar

Patent number: 10523369Abstract: Decoding and encoding methods, systems, and devices for wireless communication are described. One method may include receiving a codeword over a wireless channel, the codeword being encoded using a polar code, identifying a set of repeated bit locations in the received codeword, and identifying a set of bit locations of the polar code used for information bits for the encoding. The set of bit locations may be determined based at least in part on recursively partitioning bit-channels of the polar code for each stage of polarization and assigning portions of a number of the information bits to bit-channel partitions of each stage of polarization based on a mutual information transfer function of respective aggregate capacities of the bit-channel partitions. The method may also include decoding the received codeword according to the polar code to obtain an information bit vector at the set of bit locations, and other aspects and features.Type: GrantFiled: December 20, 2017Date of Patent: December 31, 2019Assignee: QUALCOMM IncorporatedInventors: Yang Yang, Jing Jiang, Gabi Sarkis, Huang Lou, Hari Sankar

Patent number: 9554360Abstract: Aspects of the present disclosure relate to wireless communication devices and methods configured to operate with multiple communication protocols in tune-away operations. Some aspects of the present disclosure may improve the legacy tune-away operations at an access terminal. An access terminal establishes a call utilizing a first communication protocol, tunes away from the call to receive cell signaling utilizing a second communication protocol, and tunes back to the call utilizing the first communication protocol. Following the tuning back, during a first predetermined number of subframes and if the size of a reverse link (RL) packet is smaller than a first packet size and larger than a second packet size, the access terminal forces the RL packet to be a low latency (LoLat) packet.Type: GrantFiled: June 6, 2014Date of Patent: January 24, 2017Assignee: QUALCOMM IncorporatedInventors: Meric Emre Uzunoglu, Jun Hu, Pavan C.

Patent number: 9544042Abstract: Methods and devices are disclosed for implementing opportunistic mobile receive diversity (“OMRD”) on a multi-SIM wireless device. The wireless device may receive a request from a protocol stack associated with the first SIM to utilize the second RF resource for receive diversity, and determine whether a protocol stack associated with the second SIM currently has a lower priority than the protocol stack associated with the first SIM. Upon determining that the protocol stack associated with the second SIM currently has a lower priority than the protocol stack associated with the first SIM, the wireless device may grant control of the second RF resource to the protocol stack associated with the first SIM. Granting control may provide, to the protocol stack associated with the first SIM, a capability to enable and disable receive diversity using the first and second RF resources.Type: GrantFiled: June 18, 2014Date of Patent: January 10, 2017Assignee: QUALCOMM IncorporatedInventors: Wenjun Li, Jun Hu, Huang Lou, Vansh Pal Singh Makh, Francis Ming-Meng Ngai, Ashish Gaonekar, Varsha Rao, Surekha Muralidharan
