Patent ID: 11070254

Abstract:
Described is a technology to reduce the interference between two or more transmit receive (Tx/Rx) points (TRPs) and improve the reliability for New Radio ultra reliable low latency communication (NR URLLC) applications. The technology operates in one aspect at a network node, and in another aspect at a user equipment. If a network device decides to use packet duplication, the network device can indicate duplication to the user equipment. The network device can send duplicate copies, e.g., via two different antenna panels, or can send one copy and coordinate with another network device (e.g., another cell) to send the other copy. When the user equipment receives the copies, the user equipment combines the data, e.g., via soft combining or concatenation into combined data, and decodes the combined data. Weights, such as corresponding to channel quality from each transmit source, can be used as factors in the combining of the data.
