Sidelink HARQ - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18332880 Titled 'Sidelink HARQ'
Simplified Explanation
The abstract describes a system where a user device (UE) communicates with another UE through a sidelink and with a network cell through an uplink. The UE receives a timing parameter for acknowledging data transmission (HARQ-ACK) from the network. It then creates a codebook for acknowledging data transmission on the sidelink based on communication with the other UE. The codebook is organized in a specific order related to transmission slots and feedback channels. Finally, the UE sends information about the codebook to the network cell.
Original Abstract Submitted
A user equipment (UE) communicates with a further UE via a sidelink and communicates with a cell of a network via an uplink. The UE receives a hybrid automatic repeat request (HARQ) acknowledgement (ACK) timing parameter from the network, generates a sidelink HARQ-ACK codebook based on a signaling exchange with the further UE, wherein the sidelink HARQ-ACK codebook is constructed in decreasing order of one or more physical sidelink shared channel (PSSCH) transmission slots associated with a configured physical sidelink feedback channel (PSFCH) occasion, and transmits an indication of the sidelink HARQ-ACK codebook to the cell of the network.
