Abstract
Methods and systems are provided in which a channel occupancy time (COT)-sharing indicator is received, at a first user equipment (UE), from a second UE. The first UE determines whether the first UE is able to use a time-frequency resource within a frequency range indicated by the COT-sharing indicator received from the second UE. In case that the first UE is able to use a time-frequency resource within the frequency range, data is transmitted with COT-sharing between the first UE and the second UE. In case that the first UE is unable to use a time-frequency resource within the frequency range, the data is transmitted without COT-sharing in a first resource selected by the first UE.
Claims18
A method comprising:
- receiving, at a first user equipment (UE), a channel occupancy time (COT)-sharing indicator from a second UE;
- determining, by the first UE, whether a time-frequency resource is within a frequency range indicated by the COT-sharing indicator received from the second UE, and whether the first UE is able to use the time-frequency resource;
- in case that the first UE is able to use the time-frequency resource within the frequency range, transmitting data with COT-sharing between the first UE and at least the second UE;
- and
- in case that the first UE is unable to use the time-frequency resource within the frequency range, transmitting the data without COT-sharing in a first resource selected by the first UE,
- wherein the COT-sharing indicator is received in a sidelink (SL) between the first UE and the second UE, and
- wherein the COT-sharing indicator is signaled in 1st-stage SL control information (SCI) over physical SL control channel (PSCCH) or 2nd-stage SCI over physical SL shared channel (PSSCH).
A first user equipment (UE) comprising:
- a processor;
- and
- a non-transitory computer readable storage medium storing instructions that, when executed, cause the processor to:
- receive a channel occupancy time (COT)-sharing indicator from a second UE;
- determine whether a time-frequency resource is within a frequency range indicated by the COT-sharing indicator received from the second UE, and whether the first UE is able to use the time-frequency resource;
- in case that the first UE is able to use the time-frequency resource within the frequency range, transmit data with COT-sharing between the first UE and at least the second UE;
- and
- in case that the first UE is unable to use the time-frequency resource within the frequency range, transmit the data without COT-sharing in a first resource selected by the first UE,
- wherein the COT-sharing indicator is received in a sidelink (SL) between the first UE and the second UE, and
- wherein the COT-sharing indicator is signaled in 1st-stage SL control information (SCI) over physical SL control channel (PSCCH) or 2nd-stage SCI over physical SL shared channel (PSSCH).
A communication system comprising:
- a first user equipment (UE) comprising a processor configured to:
- transmit a channel occupancy time (COT)-sharing indicator to one or more other UEs in a sidelink;
- and
- a second UE comprising a processor configured to:
- receive the COT-sharing indicator from the first UE;
- determine whether a time-frequency resource is within a frequency range indicated by the COT-sharing indicator received from the second UE, and whether the first UE is able to use the time-frequency resource;
- in case that the first UE is able to use the time-frequency resource within the frequency range, transmit data with COT-sharing between the first UE and at least the second UE;
- and
- in case that the first UE is unable to use the time-frequency resource within the frequency range, transmit the data without COT-sharing in a resource selected by the first UE,
- wherein the COT-sharing indicator is received in a sidelink (SL) between the first UE and the second UE, and
- wherein the COT-sharing indicator is signaled in 1st-stage SL control information (SCI) over physical SL control channel (PSCCH) or 2nd-stage SCI over physical SL shared channel (PSSCH).
