Electronic apparatus, wireless communication method and computer-readable medium for defining an acquisition manner of an unlicensed band resource

A method performed by an electronic device configured to operate as a base station in a wireless communication network, the method comprising:

• communicating with a first user equipment;
• and
• controlling the first user equipment to perform a sidelink communication with a second user equipment if a condition for performing the sidelink communication by the first user equipment with the second user equipment is satisfied,
• wherein controlling the first user equipment to perform the sidelink communication with the second user equipment is done by:
• transmitting, to the first user equipment, first configuration information that identifies an acquisition manner of transmission resource,
• wherein the first configuration information is included in a radio resource control (RRC) signaling and comprises one of a first value or a second value,
• wherein the first value identifies that the acquisition manner is a base station scheduled manner where the transmission resource is scheduled by the base station to the first user equipment,
• wherein the second value identifies that the acquisition manner is a user equipment selected manner where the first user equipment selects the transmission resource from a configured resource pool or a resource pool list;
• and
• configuring, to the first user equipment, information identifying the configured resource pool or the resource pool list via the RRC signaling or a system information block (SIB).

An electronic device at a user equipment side in a wireless communication network, comprising:

• a processing circuitry configured to:
• acquire control information from a base station;
• and
• perform a sidelink communication with another user equipment based on the control information if a condition for performing the sidelink communication by the first user equipment with the second user equipment is satisfied,
• wherein the processing circuitry is configured to
• receiving, from the base station, first configuration information that identifies an acquisition manner of transmission resource,
• wherein the first configuration information is included in a radio resource control (RRC) signaling and comprises one of a first value or a second value,
• wherein the first value identifies that the acquisition manner is a base station scheduled manner where the transmission resource is scheduled by the base station to the user equipment,
• wherein the second value identifies that the acquisition manner is a user equipment selected manner where the user equipment selects the transmission resource from a configured resource pool or a resource pool list;
• and
• acquiring, from the base station, information identifying the configured resource pool or the resource pool list via the RRC signaling or a system information block (SIB).

A method performed by an electronic device at a user equipment side in a wireless communication network, comprising:

• acquiring control information from a base station;
• and
• performing a sidelink communication with another user equipment based on the control information if a condition for performing the sidelink communication by the first user equipment with the second user equipment is satisfied,
• wherein the method further comprises
• receiving, from the base station, first configuration information that identifies an acquisition manner of transmission resource,
• wherein the first configuration information is included in a radio resource control (RRC) signaling and comprises one of a first value or a second value,
• wherein the first value identifies that the acquisition manner is a base station scheduled manner where the transmission resource is scheduled by the base station to the user equipment,
• wherein the second value identifies that the acquisition manner is a user equipment selected manner where the user equipment selects the transmission resource from a configured resource pool or a resource pool list;
• and
• acquiring, from the base station, information identifying the configured resource pool or the resource pool list via the RRC signaling or a system information block (SIB).
