Claim of US Patent No. 10,716,154

1. A sidelink data transmission method, comprising:transmitting, by a scheduling terminal, first physical control signaling to a transmitting terminal, wherein the first physical control signaling comprises a first transmission resource for transmitting first system information; and
transmitting, by the scheduling terminal, the first system information to the transmitting terminal, wherein the first system information comprises sidelink resource pool information,
wherein the method further comprises:
receiving second physical control signaling transmitted by the trasmitting terminal, wherein the second physical control signaling comprises the sidelink resource SR; and
receiving first high-layer control signaling transmitted by the transmitting terminal, wherein the first high-layer signaling comprises the sidelink BSR of the transmitting terminal; and
transmitting sidelink resource scheduling grant information to the transmitting terminal according to the sidelink resource SR,
wherein before receiving the sidelink resource SR transmitted by the transmitting terminal and the sidelink BSR of the transmitting terminal, the method further comprises:
executing a process of establishing the connection with the transmitting terminal;
determining that a connection has ben successfully established with the transmitting terminal; and
transmitting second high-layer control signaling to the transmitting terminal, wherein the second high-layer control signaling comprises an Identity (ID) of the transmitting terminal,
wherein the sidelink resource SR and the sidelink BSR of the transmitting terminal are transmitted after the transmitting terminal receives the second high-layer control signaling comprising the ID of the transmitting terminal,
wherein the process of establihing the connection with the transmitting terminal comprises:
trasmitting third system information to the transmitting terminal, the third system information comprises resource configuration information of an access channel;
receiving the access channel transmitted by transmitting terminal, wherein the access channel comprises an access preamble signal;
determining a transmission delay with the transmitting terminal according to the access preamble signal;
transmitting third physical control signaling to the transmitting terminal, wherein the third physical control signaling comprises feedback resource configuration information;
transmitting third high-layer control signaling to the transmitting terminal, wherein the third high-layer control signaling comprises third transmission resource configuration information and a transmission-delay-based clock regulation instruction;
receiving fourth high-layer control signaling transmitted by the transmitting terminal, wherein the fourth high-layer control signaling comprises the ID of the transmitting terminal; and
determining whether the connection has been successfully established with the transmitting terminal,
wherein the feedback resource configutation information is used for the transmitting terminal to receive the third high-layer control signaling on a feedback resource, and the fourth high-layer control signaling is transmitted on a third transmission after the transmitting terminal regulates a clock according to the clock regulation instruction.
