Abstract: Title: FEEDBACK TECHNIQUES FOR WIRELESS COMMUNICATIONS (57) : Methods, systems, and devices for wireless communication are de- scribed 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 sys- tematic CBs. In some cases, one or more parity CBs may be transmitted with the sys- tematic 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. 115, 105-c SOC Cannechum Esrnbbslunent 810 Idendfd TB and CBs fan transn and CB Transm n identify umber of missy a CB Identif for cry ' razed va um b. - of n CB, Feedback Transmisslo .„ iaenriry party CBs for transmissio or CB“o be retrensmined 840 CB' iansmi ssimdCB Bet 84\" Decode TB based on reccid d CBs 8c0 Feedback Transmission W O 20 18/ 1480 24 Al FIG. 8 (12) INTERNATIONAL APPLICATION PUBLISHED UNDER THE PATENT COOPERATION TREATY (PCT) (19) World Intellectual Property Organization International Bureau (43) International Publication Date 16 August 2018 (16.08.2018) D IV °nolo DID mil mon mum° oimIE (10) International Publication Number WO 2018/148024 Al WIPO I PCT (51) International Patent Classification: HO4L 1/16 (2006.01) H04L 1/18 (2006.01) HO4L 1/00 (2006.01) (21) International Application Number: PCT/US2018/015229 (22) International Filing Date: 25 January 2018 (25.01.2018) (25) Filing Language: English (26) Publication Language: English (30) Priority Data: 62/458,568 13 February 2017 (13.02.2017) US 15/713,335 22 September 2017 (22.09.2017) US (71) Applicant: QUALCOMM INCORPORATED [US/US]; ATTN: International IP Administration, 5775 Morehouse Drive, San Diego, California 92121-1714 (US).
