Inventors include Amiri, Abolfazl; and Pedersen, Klaus Ingemann.
The application for the patent was published on September 18, 2026, under issue no. 38/2026.
Abstract: Described herein is a User Equipment, UE, configured to support a Hybrid Automatic Repeat Request, HARQ, process when communicating with a network node of a radio access network, comprising: at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the UE at least to: receive, from the network node, a Transport Block, TB, comprising a plurality of Code Block Groups, CBGs; and for the received TB: determine, among the plurality of received CBGs, one or more CBGs that are received in error; determine a first bit string corresponding to a number of the one or more CBGs received in error; determine a second bit string indicating indices of the one or more CBGs received in error; determine a third bit string relating to a soft HARQ feedback for each CBG received in error, wherein the soft HARQ feedback for each CBG received in error comprises multiple bits; concatenate the first bit string, the second bit string and the third bit string; and transmit the concatenated bit string to the network node as HARQ feedback for the received TB, wherein the UE is further caused to: determine the first bit string based on a lookup table, wherein for each possible number of CBGs in error in the received TB, the lookup table comprises a corresponding codeword in the form of a bit string.
