Title:
CONFIGURATION METHOD AND DEVICE FOR BEAM FAILURE RECOVERY, AND COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/134089
Kind Code:
A1
Abstract:
A configuration method and device for beam failure recovery, and a communication system. The method comprises: receiving, from a network apparatus, a configuration for beam failure recovery, wherein the configuration at least comprises resource information and/or preamble information requested for beam failure recovery; and removing at least a portion of time-frequency resources and/or preambles from the configuration requested for beam failure recovery. A terminal apparatus can remove or release a resource and/or a preamble of a special-purpose configuration by itself, and can control the validity of a resource and/or a preamble of the special-purpose configuration, thereby more effectively utilizing the resource and/or the preamble of the special-purpose configuration with a reduced signaling overhead.
