Abstract
This application provides a data transmission method. The method includes: sending, by a terminal device, a first indication to an access network device, wherein the first indication is used to indicate early data transmission; and performing, by the terminal device, the early data transmission between the terminal device and the access network device.
Claims18
A data transmission method, comprising:
- sending, by an access network device, system information, wherein the system information is used to indicate a capability of early data transmission is supported;
- and
- receiving, by the access network device, a first indication to an access network device, wherein the first indication indicates early data transmission;
- and
- wherein:
- in response to the early data transmission being indicated for early uplink data transmission, performing, by the access network device, the early uplink data transmission by using a first radio resource control (RRC) signaling after the first indication, wherein the first RRC signaling is a message 3 (Msg 3);
- and
- in response to the early data transmission being indicated for early downlink data transmission, receiving, by the access network device, a service request message from a terminal device by using the Msg 3, and sending, by the access network device, downlink data to the terminal device in response to the service request message by using a message 4 (Msg 4).
A communication apparatus, comprising:
- a processor;
- and
- a transceiver;
- wherein the processor is configured to control the transceiver to send system information, wherein the system information is used to indicate a capability of early data transmission is supported;
- wherein the processor is configured to control the transceiver to receive a first indication, wherein the first indication indicates early data transmission;
- and
- wherein:
- in response to the early data transmission being indicated for early uplink data transmission, performing, by the transceiver, the early uplink data transmission by using a first radio resource control (RRC) signaling after the first indication, wherein the first RRC signaling is a message 3 (Msg 3);
- and
- in response to the early data transmission being indicated for early downlink data transmission, receiving, by the transceiver, a service request message from a terminal device by using the Msg 3, and sending, by the transceiver, downlink data to the terminal device in response to the service request message by using a message 4 (Msg 4).
A non-transitory computer readable medium storing program codes for use by an access network device for data transmission, wherein the program codes, when executed by a processor, comprise instructions for:
- sending system information, wherein the system information is used to indicate a capability of early data transmission is supported;
- and
- receiving a first indication, wherein the first indication indicates early data transmission;
- and
- wherein:
- in response to the early data transmission being indicated for early uplink data transmission, performing the early uplink data transmission by using a first radio resource control (RRC) signaling after the first indication, wherein the first RRC signaling is a message 3 (Msg 3);
- or
- wherein in response to the early data transmission being indicated for early downlink data transmission, receiving a service request message from a terminal device by using the Msg 3, and sending downlink data from the access network device in response to the service request message by using a message 4 (Msg 4).
