US 12,701,580 B2 · Transport block size and soft buffer management for shared channel transmissions

Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate a shared channel transmission (e.g., a physical uplink shared channel (PUSCH) or a physical downlink shared channel (PDSCH)) that exceeds a maximum transport block (TB) size (TBS) for the UE. A shared channel transmission may be scheduled across slot boundaries. For example, a start and length indicator value may schedule a shared channel transmission across slots. A UE may have a maximum TBS the UE is able to manage, for example, based on hybrid automatic repeat request (HARQ) buffer sizes. When the TBS indicated by the scheduling information for a shared channel transmission is greater than the maximum TBS for a UE, the shared channel transmission may be split into multiple small TBs, each having a TBS that satisfies the maximum TBS. Code block segmentation and cyclic redundancy check attachment may be per small TB.

Dependent claims

A method for wireless communications at a user equipment (UE), comprising:

receiving control signaling that schedules a set of resources for a shared channel transmission, wherein the set of resources indicates that a first transport block size for the shared channel transmission exceeds a maximum transport block size;
and
communicating the shared channel transmission via the set of resources, wherein the shared channel transmission comprises a plurality of transport blocks associated with respective code blocks and respective cyclic redundancy check bits, and wherein a second transport block size for each of the plurality of transport blocks is based at least in part on the maximum transport block size.

A user equipment (UE), comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to:
receive control signaling that schedules a set of resources for a shared channel transmission, wherein the set of resources indicates that a first transport block size for the shared channel transmission exceeds a maximum transport block size;
and
communicate the shared channel transmission via the set of resources, wherein the shared channel transmission comprises a plurality of transport blocks associated with respective code blocks and respective cyclic redundancy check bits, and wherein a second transport block size for each of the plurality of transport blocks is based at least in part on the maximum transport block size.

A network entity, comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the network entity to:
output control signaling that schedules a set of resources for a shared channel transmission, wherein the set of resources indicates that a first transport block size for the shared channel transmission exceeds a maximum transport block size;
and
communicate the shared channel transmission via the set of resources, wherein the shared channel transmission comprises a plurality of transport blocks associated with respective code blocks and respective cyclic redundancy check bits, and wherein a second transport block size for each of the plurality of transport blocks is based at least in part on the maximum transport block size.
