FRAME-BASED EQUIPMENT MODE OF OPERATION FOR NEW RADIO-UNLICENSED SYSTEMS AND NETWORKS

摘要

A mode of operation is provided for user equipment (UE) communicating in unlicensed carrier (e.g., NR-unlicensed). The UE is configured to operate in one or more modes of operation, including FBE and LBE. The UE can be configured to operate in FBE, where the equipment has a fixed frame period according to CCA, or in LBE, where the equipment determines whether the channel is idle or not and transmits only when the channel is clear. The UE is configured to operate in a mode of operation to be used in the communicating with a communication network (e.g., a cellular network), where the UE can transmit and/or receive one or more listen before talk (LBT) messages with the communication network through a Radio Access Network (RAN) based on the mode of operation.
