METHOD AND APPARATUS FOR RESOURCE MAPPING OF PDSCH ON UNLICENSED SPECTRUM - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18344763 Titled 'METHOD AND APPARATUS FOR RESOURCE MAPPING OF PDSCH ON UNLICENSED SPECTRUM'
Simplified Explanation
This abstract describes a method and apparatus for accessing shared spectrum channels in a wireless communication system. The system receives a set of downlink channels that support shared spectrum channel access. It then identifies a window for transmitting SS/PBCH blocks, a bitmap for the positions of these blocks, and a parameter for QCL assumption Q. Based on these identifications, the system determines whether a specific SS/PBCH block is assumed to be transmitted by the base station (BS) or not. It also determines a set of resources that are not available for at least one PDSCH (Physical Downlink Shared Channel) due to overlap with the first set of SS/PBCH blocks. Finally, the system receives the PDSCH using resources other than the determined set.
Original Abstract Submitted
A method and apparatus in a wireless communication system supporting shared spectrum channel access is provided. The method and apparatus comprises: receiving a set of downlink channels supporting the shared spectrum channel access; identifying, a window for SS/PBCH block transmission, a bitmap for SS/PBCH blocks (ssb-PositionsInBurst), and a parameter for QCL assumption Q; determining, based on the identified window for the SS/PBCH block transmission, the identified bitmap for the ssb-PositionsInBurst, and the identified parameter for the QCL assumption Q, a SS/PBCH block as one of: a first set of SS/PBCH blocks assumed to be transmitted by the BS, or a second set of SS/PBCH blocks not transmitted by the BS; determining a set of resources that is not available for at least one PDSCH as overlapped with the first set of SS/PBCH blocks; and receiving the at least one PDSCH based on resource other than the determined set of resources.
