Abstract
In a data transmission method, a terminal can determine, based on the transmission resource occupation status information broadcast by the base station, the transmission resource unit used to send the first data packet. This avoids a problem in a non-scheduled solution that a terminal does not know transmission resource occupation status information, and sends a first data packet by using a transmission resource unit that cannot be used to transmit a data packet; and reduces a latency for sending a data packet.
Claims20
A data transmission method, comprising:
- obtaining, by a terminal, transmission resource occupation status information broadcast by a base station, wherein the transmission resource occupation status information comprises a status that at least one transmission resource unit in a transmission resource within preset duration is occupied by another terminal;
- determining, by the terminal based on the transmission resource occupation status information, a transmission resource unit used to send the first data packet, wherein a size of the first data packet is not greater than a maximum size of data that one transmission resource unit is allowed to carry;
- and
- sending, by the terminal, the first data packet by using the determined transmission resource unit.
A data transmission method, comprising:
- determining, by a base station, transmission resource occupation status information, wherein the transmission resource occupation status information comprises a status that at least one transmission resource unit in a transmission resource within preset duration is occupied by a terminal under control of the base station, and a size of the data packet is not greater than a maximum size of data that one transmission resource unit is allowed to carry;
- and
- broadcasting, by the base station, the transmission resource occupation status information.
An apparatus, comprising:
- a transceiver, configured to obtain transmission resource occupation status information broadcast by a base station, wherein the transmission resource occupation status information comprises a status that at least one transmission resource unit in a transmission resource within preset duration is occupied by another terminal;
- and
- a processor, configured to determine, based on the transmission resource occupation status information, a transmission resource unit used to send a first data packet, wherein a size of the first data packet is not greater than a maximum size of data that one transmission resource unit is allowed to carry, wherein
- the transceiver is configured to send the first data packet by using the determined transmission resource unit.
An apparatus, comprising:
- a processor, configured to determine transmission resource occupation status information, wherein the transmission resource occupation status information comprises a status that at least one transmission resource unit in a transmission resource within preset duration is occupied by a terminal under control of the apparatus, and a size of the data packet is not greater than a maximum size of data that one transmission resource unit is allowed to carry;
- and
- a transceiver, configured to broadcast the transmission resource occupation status information.
