Description
Technical Field
The present invention relates to the field of communications, and in particular, to a data transmission method, a terminal device, a network device, and a computer-readable storage medium.
Background
When small data with low real-time requirement is transmitted, the interaction of wireless resources and wireless signaling and the modem (modem) wake-up duration need to be applied, but the standby power consumption of the terminal equipment is increased. Taking a smart watch as an example, the amount of Transmission Control Protocol (TCP) heartbeat information data transmitted each time is small, and the delay requirement is not very high. However, each time such data is transmitted, a Radio Resource Control (RRC) connection needs to be established, the duration of the RRC connection is about 10s, and the average current in 10s during which the modem wakes up to maintain the RRC connection state is about 120 milliamperes (mA). Assuming such data is sent once in 10 minutes, the average current per hour will rise by around 2mA and the overall machine current will rise to 5-6 mA. It can be seen that the current drawn during the duration of the RRC setup is approximately 1/3 times the overall standby current when small data transmissions are made.

201. the method comprises the steps that terminal equipment sends auxiliary information to network equipment, wherein the auxiliary information comprises indication information that the terminal equipment enters a wireless resource control idle state and indication information that the terminal equipment supports target data transmission in the wireless resource control idle state, and the auxiliary information is used for the network equipment to configure relevant transmission parameters of the target data.
It should be noted that, in the embodiment of the present invention, the target data may also be referred to as small data, and a standard of the size of the small data may be defined first, so as to conveniently determine whether the data is the small data, and to conveniently reserve reasonable resources for the network device. The size of the target data is smaller than a preset threshold. Illustratively, data of 64 bits (byte) or less is small data, and data of 64 bytes or more cannot be referred to as small data.
Optionally, the small data may include information such as an IP (Internet Protocol) in consideration of additional information such as an IP header.
The network equipment receives auxiliary Information (Assistance Information) sent by the terminal equipment, and the network equipment obtains the relevant transmission parameters of the target data through the auxiliary Information. Wherein the relevant transmission parameters of the target data may include: the target data comprises a radio network temporary identifier (small data-RNTI, SD-RNTI) of the target data, a Discontinuous Reception cycle (SD-DRX) of the target data, and reserved resource information of the target data.
For example, in order to support small data transmission, the related protocol content may be modified on the current 38.331 protocol to achieve the function of supporting small data transmission. The terminal is arranged when the Assistance Information is sent to the base station, wherein the Assistance Information carries parameters which indicate that the terminal equipment is about to enter an RRC idle state and support small data transmission by the terminal equipment. As follows:
it should be noted that the bold part is an entry (IE) newly added in the present invention, 0 indicates that the terminal device does not support the transmission of the small data in the RRC idle state, and 1 indicates that the terminal device supports the transmission of the small data in the RRC idle state.
202. And the network equipment sends the relevant parameters of the target data to the terminal equipment, wherein the relevant parameters of the target data are obtained through the auxiliary information, and the relevant parameters of the target data are used for the terminal equipment to transmit the target data.
And the terminal equipment receives the relevant transmission parameters of the target data sent by the network equipment. The radio network temporary identifier of the target data and the discontinuous reception period of the target data are carried in release information of the unlimited resource control connection issued to the terminal device by the network device, and the reserved resource information of the target data is carried in downlink control information issued to the terminal device by the network device.
Optionally, the network device sends RRC release information and DCI information to the terminal device, where the RRC release information carries SD-RNTI and SD-DRX of the target data, and the DCI information carries the reserved resource information of the target data.
Optionally, the sending, by the network device, the relevant parameter of the target data to the terminal device may include: and under the condition that the network equipment supports the target data transmission, the network equipment sends the relevant parameters of the target data to the terminal equipment.
Illustratively, the network device sends RRC release information and DCI information to the terminal device, where the rrrelease information carries SD-RNTI and SD-DRX of the target data. Taking the network device as the base station for illustration, the base station may include the following messages in the RRC release message:
it should be noted that, the bold part is an entry (IE) newly added in the present invention, that is, a small Data transmission configuration (small Data Transmit Config) is newly added, and may be used to configure a Radio Network Temporary Identity (RNTI) of the small Data and a special DRX cycle of the small Data, as follows:
it can be understood that the small data radio network temporary identifier (SD-RNTI) during the RRC idle state has uniqueness, and can be used for the terminal device to decode resource indication Information for small data transmission in Downlink Control Information (DCI) sent by the network device.
The small data discontinuous reception cycle (SD-DRX) is a special DRX cycle, the configuration range can be 0-1023, and the method is used for the base station to transmit the DCI information which contains the configuration of small data resources at the special DRX cycle. That is, if the base station has an empty resource allocated to the terminal device for transmitting small data, the base station configures the DCI information including the small data resource configuration in this special DRX cycle. The terminal device needs to use the SD-RNTI to analyze the DCI information in this special DRX cycle, so as to obtain the information of the frequency domain and the time domain of the uplink reserved resource allocated by the base station. If the parsing is successful, the UE will transmit small data on the reserved time-frequency resources.
203. And the terminal equipment transmits the target data according to the related transmission parameters of the target data.
The terminal device transmits the target data according to the relevant transmission parameters of the target data, and the implementation manners may include, but are not limited to, the following implementation manners:
the implementation mode is as follows: and under the condition that the terminal equipment enters a wireless resource control idle state, the terminal equipment transmits the target data according to the relevant transmission parameters of the target data. Alternatively, the first and second electrodes may be,
the implementation mode two is as follows: the terminal equipment decodes the downlink control information in the discontinuous receiving period of the target data according to the wireless network temporary identifier of the target data to obtain the reserved resource information of the target data; and the terminal equipment uses the reserved resource information of the target data to transmit the target data. Alternatively, the first and second electrodes may be,
the implementation mode is three: under the condition that the terminal equipment enters a wireless resource control idle state, the terminal equipment decodes the downlink control information in a discontinuous receiving period of the target data according to the wireless network temporary identifier of the target data to obtain reserved resource information of the target data; and the terminal equipment uses the reserved resource information of the target data to transmit the target data.
Exemplarily, as shown in fig. 3, the method for transmitting small data in the embodiment of the present invention is schematically illustrated in one embodiment. As shown in fig. 3, the following description is made:
the terminal equipment sends the Assistance Information to the base station, wherein the Assistance Information comprises indication Information that the terminal equipment is about to enter an RRC idle state and indication Information supporting small data transmission when the terminal equipment is in the RRC idle state.
If the base station supports small data transmission, related parameters of the small data transmission can be configured in an RRC release message and sent to the terminal equipment, wherein the related parameters of the small data transmission comprise SD-RNTI, SD-DRX and reserved resource information of small data.
The terminal device detects if the data sent from the IP layer reaches a Media Access Control (MAC) layer. The terminal device may first determine whether to establish an RRC connection, and if the RRC connection is established, may use the existing uplink resource for data transmission. If the RRC connection is not established, the terminal device may determine whether the base station supports small data transmission according to the related parameters of small data transmission.
If the terminal equipment determines that the base station does not support the small data transmission according to the relevant parameters of the small data transmission, the RRC connection can be established for data transmission. If the base station is determined to support the small data transmission, for example, the relevant parameter of the small data transmission includes the reserved resource information of the small data, the base station may be considered to support the transmission of the small data; then, when the special SD-DRX cycle arrives, the DCI information may be analyzed to determine whether there is a reserved uplink resource for the terminal device to transmit small data, and if there is a reserved resource, the reserved resource is used to transmit the small data, and a response is waited on a Physical Downlink Control Channel (PDCCH) Channel.
If no resources are reserved, the terminal device may initiate RRC connection, perform a normal data transmission procedure, and transmit small data. If other uplink IP data reach the MAC layer before waiting for the special SD-DRX period to arrive, the waiting process can be interrupted, RRC connection is initiated, and a normal data transmission process is carried out.
And if the terminal equipment determines that the base station does not support the small data transmission according to the relevant parameters of the small data transmission, the terminal equipment initiates RRC connection, performs a normal data transmission process and transmits the small data.
In the embodiment of the invention, terminal equipment sends auxiliary information to network equipment, wherein the auxiliary information comprises indication information that the terminal equipment is to enter a wireless resource control idle state and indication information that the terminal equipment supports target data transmission in the wireless resource control idle state, and the auxiliary information is used for the network equipment to configure relevant transmission parameters of the target data; the terminal equipment receives the relevant transmission parameters of the target data sent by the network equipment; and the terminal equipment transmits the target data according to the related transmission parameters of the target data. The method can reduce the signaling establishment process and power consumption of RRC during target data transmission, reduce the power consumption of the terminal equipment and prolong the standby time of the terminal equipment. Further, in the 5G NR, the terminal device sends the auxiliary information to the network device, and combines the relevant transmission parameters of the target data sent by the network device, where the relevant transmission parameters of the target data include: the wireless network temporary identifier of the target data, the discontinuous receiving period of the target data and the reserved resource information of the target data; the method and the device achieve the effects of reducing the power consumption of the RRC signaling establishment process during target data transmission and prolonging the standby time of the mobile terminal.
