Methods and apparatus for conditional offload of one or more log-likelihood ratios (LLRs) or decoded bits

摘要

Techniques and apparatus are provided for conditional offload of one or more LLRs or decoded bits. An exemplary electronic device (ED) method includes receiving a transmission of a physical downlink shared channel (PDSCH) having a transport block (TB) comprising at least one code block (CB), performing a cyclic redundancy check (CRC) of the at least one CB, in a memory external to a modem core of the ED, storing a subset of log-likelihood ratios (LLRs) associated with the at least one CB if the at least one CB failed the CRC or decoded bits associated with the at least one CB if the at least one CB passed the CRC, wherein the subset is based on an LLR range of the transmission relative to an LLR range of one or more previous transmissions, and using the stored subset of LLRs or decoded bits to process a re-transmission of the PDSCH.

receiving a transmission of a physical downlink shared channel (PDSCH) having a transport block (TB) comprising at least one code block (CB); performing a cyclic redundancy check (CRC) of the at least one CB; in a memory external to a modem core of the electronic device, storing a subset of log-likelihood ratios (LLRs) associated with the at least one CB if the at least one CB failed the CRC or decoded bits associated with the at least one CB if the at least one CB passed the CRC, wherein the subset is based on an LLR range of the transmission relative to an LLR range of one or more previous transmissions; and using the stored subset of LLRs or decoded bits to process a re-transmission of the PDSCH.
