Title:
METHOD, DEVICE AND COMPUTER READABLE MEDIUM OF COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2023/173378
Kind Code:
A1
Abstract:
Embodiments of the present disclosure relate to method, device and computer readable medium of communication. A terminal device deployed with first and second sets of antenna ports receives DCI for scheduling an uplink transmission, the DCI comprising a first SRI and a second SRI. The terminal device determines a first set of antenna port indexes based on a first number of layers of the uplink transmission indicated by the first SRI and indexes of SRS resources in a first set of SRS resources, and determines a second set of antenna port indexes based on indexes of SRS resources in a second set of SRS resources, a second number of layers of the uplink transmission indicated by the second SRI and the number of SRS resources in the first set of SRS resources. Then the terminal device performs the uplink transmission over antenna ports corresponding to the first and second sets of antenna port indexes. In this way, a simultaneous transmission across multi-panels is well supported.
