In an optional embodiment of the present invention, the transmission jitter control method further includes:

The scheme of the invention provides a transmission jitter control method in the field of industrial Internet of things, and solves the problem of resource waste.
According to the embodiment of the present invention, the transmission jitter control method can be specifically described by the following four embodiments.
Example 1:
the transmission jitter control method according to an embodiment of the present invention includes the steps of:
and step 11, the terminal reports the capability of supporting the jitter control to the network side through RRC signaling or MAC CE.
And step 12, the terminal obtains the jitter value of each configuration authorization moment or the average value or value range of the jitter of the configuration authorization moments in a period of time through a jitter calculation formula.
The calculation formula of the jitter value or range described here is:
T dithering ＝T Configuring a first uplink symbol authorizing configured PUSCH transmission -T Configuring the first uplink symbol of the authorized PUSCH actual data transmission
Step 13, the network side configures a jitter reporting threshold to the terminal through RRC signaling, and if the jitter value or range of each configuration authorization time calculated through the above calculation formula exceeds the configured jitter reporting threshold or threshold range, the terminal reports the condition that the time delay of the current configuration authorization is too large to the network side through the MAC CE or UCI. The threshold reflects that the QoS requirement of the industrial Internet of things cannot be met due to overlarge jitter or the overlarge jitter can be used as a reference for adjusting physical resource allocation of the base station.
Fig. 5 shows a format of the MAC CE. Wherein the CGi indicates whether the jitter of the CG i exceeds a reporting threshold or threshold range. If the CGi bit is set to 1, it indicates that the jitter of CGi exceeds a configured threshold value or threshold range. If the CGi bit is set to 0, it indicates that the CGi jitter does not exceed the reported configured threshold or threshold range.
The UCI can directly indicate whether the jitter of the CG i exceeds a reporting threshold value or a threshold range by using a bitmap, and if the bit of the CGi is set to be 1, the UCI indicates that the jitter of the CGi exceeds the reporting threshold value or the threshold range. If the CGi bit is set to 0, it indicates that the CGi jitter does not exceed the reporting threshold or threshold range.
Step 14, the terminal reports the jitter value or range to the network side, where the reporting may be periodic reporting through configuration, network side triggered reporting, or UE triggered reporting. And reporting the jitter value or range of the current configuration authorization moment to a network side through the MAC CE or the UCI.
Fig. 6 shows the format of the MAC CE, where the CG ID indicates the index number of the uplink configuration grant. Jitter value represents a Jitter value or range.
Step 15, the network side reports the MAC CE or UCI sensing jitter through the received terminal, and optionally reconfigures the configuration authorization.
Example 2:
the transmission jitter control method according to an embodiment of the present invention includes the steps of:
step 21, the terminal reports the capability of supporting jitter control to the network side through RRC signaling or MAC CE.
Step 22, the network side determines the jitter scheduling group ID or code of the UE according to the UPF and/or AMF and/or SMF determined in the UE registration or access process. Optionally, the network side configures a jitter scheduling group ID and/or code for the terminals in the jitter scheduling group through RRC signaling or MAC CE.
And step 23, the network side configures an A-RNTI for the terminal in the jitter scheduling group through RRC signaling or MAC CE. The a-RNTI is used for the terminal to receive jitter information, and the format of a-RNTI MAC CE is shown in fig. 7.
And 24, the network side obtains a downlink jitter value or a value range through measurement or configuration.
Optionally, the UPF sends the jitter information to the base station through a paging message or an Ng interface message, and the reporter sends the jitter information to the terminal.

the effective time and/or period of the downstream jitter.
And step 25, the network side sends a paging message or other common RRC messages to the UEs belonging to the same jitter scheduling group in the coverage area.
And the network side scrambles the PDCCH by using the A-RNTI, and the PDCCH information indicates a data packet carrying the message. The message may carry at least one of the following information:
a jitter scheduling group ID and/or code;
a downlink relative jitter value or value range; the relative reference may be a data arrival time or an expected data arrival time;
starting symbols and/or starting time slots and/or ending symbols and/or ending time slots of downlink jitter;
an effective starting symbol interval;
the effective time and/or period of downstream jitter.
And step 26, the UE belonging to the same jitter scheduling group receives the PDCCH scrambled by the A-RNTI, descrambles the PDCCH, obtains a data packet carrying the message and indicated by the PDCCH information, and transmits the data packet to an upper layer, so that the data packet containing the jitter information is obtained. And the network side indicates whether the terminal needs to carry out jitter compensation or not according to the jitter message.
Example 3:
the transmission jitter control method according to an embodiment of the present invention includes the steps of:
step 31, the terminal reports the capability of supporting jitter control to the network side through RRC signaling or MAC CE.
And step 32, the network side configures a B-RNTI for the terminal through RRC signaling or MAC CE. The B-RNTI is used for the terminal to receive jitter information. The format of B-RNTI MAC CE is shown in FIG. 7.
And step 33, the network side indicates the terminal downlink jitter information through the dynamic PDCCH DCI indication or the MAC CE indication. The message utilizes the B-RNTI to scramble PDCCH DCI or data packets carrying the message.
The information may carry at least one of the following information:
a downlink relative jitter value or value range; the relative reference may be a data arrival time or an expected data arrival time
Starting symbol and/or starting time slot and/or ending symbol and/or ending time slot of downlink jitter

And step 34, the terminal side receives the B-RNTI scrambled PDCCH DCI or data packet carrying the message, and the downlink jitter information is obtained through the B-RNTI descrambling dynamic PDCCH DCI indication or the MAC CE indication.
As shown in fig. 8, the terminal re-determines, at the UE, a PDSCH transmission start symbol or a PDSCH transmission start timeslot or a PDSCH transmission start PRB index and/or re-determines a PDSCH transmission receiving duration according to the received downlink jitter information.
