Slot format indicator enhancements for new radio-unlicensed
First Claim
Patent Images
1. A method of wireless communication, comprising:
- receiving, at a user equipment (UE), a slot format indicator (SFI) from a serving base station, wherein the SFI identifies a symbol status of each symbol of a plurality of slots within a current transmission opportunity (TxOP);
receiving, at the UE, a channel occupancy time (COT) range indication for a current COT of one or more COTs of the current TxOP, wherein the COT range indication identifies parameters of a three-segment structure of the current COT including a first COT segment, a second COT segment, and a third COT segment; and
engaging, by the UE, in communication with the serving base station in at least the first COT segment in accordance with the COT range indication and the SFI.

Abstract
Enhancements to slot format indicator (SFI) for new radio (NR) unlicensed (NR-U) operations is disclosed. The SFI may be transmitted separately from a channel occupancy time (COT) range indication. The COT range indication identifies parameters of a three-segment structure of a current COT within the current TxOP. Upon receiving the SFI and COT range indication, a UE may engage in communications with the serving UE in accordance with the COT range indication and the SFI.

14. A method of wireless communication, comprising:
-
detecting, by a base station, a channel occupancy time (COT) range indication of a neighboring base station, wherein the COT range indication identifies at least a segment level state indicator of a three-segment structure of a current COT of one or more COTs of the current TxOP of the neighboring base station; and scheduling, by the base station, transmissions with one or more served user equipments (UEs) based in part on the segment level state indicator for the neighboring base station. - View Dependent Claims (15)
