HYBRID AUTOMATIC REPEAT REQUEST FEEDBACK CODEBOOK FOR MULTI-CELL SCHEDULING - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18178989 Titled 'HYBRID AUTOMATIC REPEAT REQUEST FEEDBACK CODEBOOK FOR MULTI-CELL SCHEDULING'
Simplified Explanation
The abstract describes a wireless communication system where a user device (UE) receives data transmissions on a shared channel. The UE then sends feedback about the received data using a specific sub-codebook from a set of sub-codebooks. The choice of sub-codebook depends on the type of scheduling information received by the UE. The abstract mentions that there are other aspects of the disclosure that are not described in detail.
Original Abstract Submitted
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more physical downlink shared channel (PDSCH) communications scheduled by downlink control information (DCI). The UE may transmit, for the one or more PDSCH communications, hybrid automatic repeat request (HARQ) feedback using a sub-codebook of a set of sub-codebooks, wherein the sub-codebook is a single-cell scheduling sub-codebook, of the set of sub-codebooks, or a multi-cell scheduling sub-codebook, of the set of sub-codebooks, based at least in part on whether the DCI is a first format configured for scheduling on a single carrier or a second format configured for scheduling on a plurality of carriers. Numerous other aspects are described.
