Definitions
- the display 208 may include any known electronically controllable display or display device.
- the display 208 may be designed to output visual, audible, and/or haptic signals.
- the display 208 includes an electronic display capable of outputting visual data to a user.
- the display 208 may include, but is not limited to, a liquid crystal display (“LCD”), a light emitting diode (“LED”) display, an organic light emitting diode (“OLED”) display, a projector, or similar display device capable of outputting images, text, or the like to a user.
- the display 208 may include a wearable display such as a smart watch, smart glasses, a heads-up display, or the like.
- the display 208 may be a component of a smart phone, a personal digital assistant, a television, a table computer, a notebook (laptop) computer, a personal computer, a vehicle dashboard, or the like.
- the transmitter 310 transmits a signal in a communication system.
- the signal includes a channel occupancy sharing indicator, and the channel occupancy sharing indicator is applicable to a spatial transmission characteristic, a spatial reception characteristic, or a combination thereof.
- restricting COT sharing only with cell specific beams may be considered for UE initiated COT.
- a UE may identify a COT sharing indicator among multiple COT sharing indicators to be applicable for itself to do either category 1 (“Catl”) or Cat2 LBT under 2 possibilities: 1) once the UE is configured with configured grant (“CG”) resources and corresponding TCI states (e.g., UL transmit (“TX”) beams), and then the UE determines COT sharing applicability by comparing whether the TCI associated with COT is QCLed (e.g., with type D assumption) with that of TCI indicated for that UE for CG resources; and 2) if the UE is not indicated with any UL TX for its CG resources, then the TCI state (e.g., downlink (“DL”) receive (“RX”) beam) used for receiving a DL physical downlink control channel (“PDCCH”) (e.g., group common DCI and/or UE specific DCI) is compared with the TCI state and corresponding COT, and based on that determines the COT.
- CP configured grant
- TCI states e.g.
- FIG. 4 is a schematic block diagram illustrating one embodiment of a system 400 for configuring channel occupancy sharing.
- the system 400 includes a UE 402 and a gNB 404. Each of the communications in the system 400 may include one or more messages.
- the UE 402 receives a signal in a communication system.
- the signal includes a channel occupancy sharing indicator, and the channel occupancy sharing indicator is applicable to a spatial transmission characteristic, a spatial reception characteristic, or a combination thereof.
- the UE 402 applies 408 the channel occupancy sharing indicator to a transmission, a reception, or a combination thereof.
- the spatial transmission characteristic, the spatial reception characteristic, or the combination thereof is a preconfigured transmission configuration indicator (TCI) state or quasi-colocation relationship.
- TCI transmission configuration indicator
- the spatial transmission characteristic for a transmission transmitted by the apparatus corresponds to the spatial reception characteristic for a reception received by the apparatus.
- the channel occupancy sharing indicator is included in a control message transmitted in the communication system.
- a mapping between the channel occupancy time sharing field and a synchronization signal block (SSB) index is determined based on a predefined order.

Abstract
Sont divulgués des appareils, des procédés et des systèmes pour configurer un partage d'occupation de canal. Un procédé (500) consiste à recevoir (502) un signal dans un système de communication. Le signal comprend un indicateur de partage d'occupation de canal, et l'indicateur de partage d'occupation de canal est applicable à une caractéristique de transmission spatiale, à une caractéristique de réception spatiale ou à une combinaison de celles-ci. Le procédé (500) comprend l'application (504) de l'indicateur de partage d'occupation de canal à une transmission, à une réception ou à une combinaison de celles-ci.
