PDCCH RELIABILITY ENHANCEMENTS WITH MULTIPLE TRPs - A simplified explanation of the abstract
This abstract first appeared for US patent application 17797634 titled 'PDCCH RELIABILITY ENHANCEMENTS WITH MULTIPLE TRPs
Simplified Explanation
The patent application describes a method for improving the reliability of a physical downlink control channel (PDCCH) transmission and reception in a cellular communications system. The method involves receiving a configuration of two control resource sets (CORESETs) and receiving repetitions of the PDCCH carrying downlink control information (DCI) in each CORESET. The repetitions of the PDCCH can have different channel encoding or the same channel encoding. The DCI is decoded based on the received repetitions of the PDCCH.
- The method improves the reliability of PDCCH transmission and reception.
- It involves receiving repetitions of the PDCCH in different CORESETs.
- The repetitions of the PDCCH can have different or the same channel encoding.
- The DCI is decoded based on the received repetitions of the PDCCH.
Potential Applications
- Cellular communications systems
- Wireless communication devices
Problems Solved
- Improving the reliability of PDCCH transmission and reception
Benefits
- Enhanced reliability of PDCCH transmission and reception
- Improved decoding of downlink control information (DCI)
Original Abstract Submitted
Systems and methods are disclosed herein for improving the reliability of a physical downlink control channel (PDCCH) transmission and reception. In one embodiment, a method performed by a wireless communication device for reception of PDCCH repetitions over multiple control resource sets (CORESETs) in a cellular communications system comprises receiving a configuration of a first CORESET and a second CORESET. The method further comprises receiving, from one or more network nodes, a first repetition of a PDCCH carrying downlink control information (DCI) in the first CORESET and a second repetition of the PDCCH carrying the same DCI in the second CORESET, wherein the first and second repetitions of the PDCCH have either: (a) different channel encoding or (b) a same channel encoding. The method further comprises decoding the DCI based on the first repetition of the PDCCH and/or the second repetition of the PDCCH.
