Electronic device and method for wireless communication and computer-readable storage medium
The present disclosure provides an electronic device and a method for wireless communication and a computer-readable storage medium. An electronic device comprising: a processing circuit configured to: generate, where a user equipment accesses an unauthorized frequency band successfully, an indication representing whether sharing a channel occupancy time of the user equipment with other user equipment is permitted; and send the indication to a base station or the other user equipment.
1. An electronic apparatus configured to operate as user equipment (UE) for wireless communications, comprising:
processing circuitry, configured to:
access into an unlicensed frequency band in accordance with a channel occupancy time assigned to the UE;
after the UE has accessed into the unlicensed frequency band, determine whether or not a portion of the channel occupancy time assigned to the UE may be shared with another UE; and
upon determining that the portion of the channel occupancy time assigned to the UE may be shared with the another UE, transmit channel occupancy time sharing information to the another UE,
wherein the portion of the channel occupancy time is shared with the another UE through a physical sidelink shared channel of the UE.
2. The electronic apparatus according to claim 1 , wherein the processing circuitry is configured to transmit the indication to the base station in uplink control information.
3. The electronic apparatus according to claim 2 , wherein the processing circuitry is configured to add an information bit of one bit in the uplink control information for the indication, or
wherein the processing circuitry is configured to transmit the indication by multiplexing a channel occupancy time sharing indicator in the uplink control information,
wherein the channel occupancy time sharing indicator indicates whether to allow the base station to transmit control signaling by sharing the channel occupancy time of the UE.
4. The electronic apparatus according to claim 1 , wherein the processing circuitry is configured to transmit the indication to the other UE through a physical sidelink control channel.
5. The electronic apparatus according to claim 1 , wherein the processing circuitry is configured to comprise the information in the uplink control information, to be transmitted to the base station, or
wherein the processing circuitry is configured to comprise the information in sidelink control information, to be transmitted to the other UE.
6. The electronic apparatus according to claim 1 , wherein the indication indicates that the other UE may access into spectrum resources within the portion of the channel occupancy time assigned to the UE without performing channel detection by the other UE.
7. A method performed by an electronic apparatus configured to operate as a user equipment (UE) for wireless communications, the method comprising:
accessing into an unlicensed frequency band in accordance with a channel occupancy time assigned to the UE,
after the accessing into the unlicensed frequency band, determining whether or not a portion of the channel occupancy time assigned to the UE may be shared with another UE; and
upon determining that the portion of the channel occupancy time assigned to the UE may be shared with the another UE, transmitting channel occupancy time sharing information to the another UE,
wherein the portion of the channel occupancy time is shared with the another UE through a physical sidelink shared channel of the UE.
8. A non-transitory computer readable product containing instructions for causing a user equipment (UE) to perform a method, the method comprising:
accessing into an unlicensed frequency band in accordance with a channel occupancy time assigned to the UE,
after the accessing into the unlicensed frequency band, determining whether or not a portion of the channel occupancy time assigned to the UE may be shared with another UE; and
upon determining that the portion of the channel occupancy time assigned to the UE may be shared with the another UE, transmitting channel occupancy time sharing information to the another UE,
wherein the portion of the channel occupancy time is shared with the another UE through a physical sidelink shared channel of the UE.
