US 11,083,018 B2 · Transmission structure with beamforming for a radio system

Abstract

A wireless device receives one or more messages. The one or more messages comprise configuration parameters of a cell. The configuration parameters indicate: a plurality of slot format combinations of the cell; a plurality of reference signals (RS) of the cell; and a channel occupancy time (COT) radio network temporary identifier (RNTI). The wireless device receives a downlink control information (DCI) scrambled by the COT-RNTI indicating a slot format combination of the plurality of slot format combinations, for an RS of the plurality of RSs. A channel occupancy time (COT) structure is determined for the RS based on the slot format combination. A transport block is transmitted, via uplink resources of the cell, based on the COT structure.

A method comprising:

receiving, by a wireless device, one or more messages comprising configuration parameters of a cell, wherein the configuration parameters indicate:
a plurality of slot format combinations of the cell;
a plurality of reference signals (RS) of the cell;
and
a channel occupancy time (COT) radio network temporary identifier (RNTI);
receiving a downlink control information (DCI) scrambled by the COT-RNTI indicating a slot format combination, of the plurality of slot format combinations, for an RS of the plurality of RSs;
determining a channel occupancy time (COT) structure for the RS based on the slot format combination;
and
transmitting, via uplink resources of the cell, a transport block based on the COT structure.
