Title:
METHODS FOR COMMUNICATION, TERMINAL DEVICE, NETWORK DEVICE, AND COMPUTER READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/062719
Kind Code:
A1
Abstract:
Embodiments of the present disclosure provide a solution for. In a method for communication, a terminal device receives, from a network device, control information indicating a set of resources and transmission configuration indicator (TCI) states for a communication between the terminal device and the network device. The terminal device determines resource subsets associated with the respective TCI states, each resource subset being a part of the set of resources in frequency domain. The terminal device determines a mapping of phase-tracking reference signals (PT-RSs) to the resource subsets. Embodiments of the present disclosure provide practical details on how to decide PT-RS presence/density/pattern/offset if a scheduled set of resources are shared by a plurality of TCI states, especially in case of scheme 2a/2b.
