Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a transmission jitter control method, user equipment and network side equipment. Background Art

[0002] The services supported by the existing industrial Internet of Things are mainly control commands for machine-to-machine communication, which are generally deterministic and periodic. By deploying 5G high-reliability and low-latency communication technology, the performance index requirements of the industrial Internet of Things can be met. Multi-configuration authorization is a solution introduced in the Industrial Internet of Things R16. Compared with dynamic scheduling, multi-configuration authorization avoids the delay between physical downlink control channel PDCCH scheduling and physical uplink shared channel PUSCH transmission, and can adapt to the deterministic and periodic characteristics of different services.

[0003] Jitter is the difference between the delay values ​​of two data packets. It usually causes packet loss and network congestion. In current technology, the jitter solution for the Industrial Internet of Things has not been discussed in detail. Faced with the jitter problem that may exist in any cycle and transmission link of the Industrial Internet of Things service, and the high reliability and low latency of the Industrial Internet of Things, these problems can only be solved by configuring authorization with a more intensive configuration cycle, or configuring more configuration authorizations at the same time, or increasing the time and frequency domain resources of the configuration authorization. These methods will introduce different degrees of resource waste due to the characteristics of the service. Summary of the invention

[0136] Step 310, sending jitter control capability information to the network side device;

[0153] Step 410, receiving jitter control capability information sent by user equipment;

[0157] Reconfigure the configuration authorization based on the jitter related data.

[0158] The above solution of the present invention provides a transmission jitter control method in the field of industrial Internet of Things, which overcomes the problem of resource waste.

[0159] According to an embodiment of the present invention, the transmission jitter control method can be specifically described through the following four embodiments.

[0160] Embodiment 1:

[0161] The transmission jitter control method according to an embodiment of the present invention comprises the following steps:

[0162] Step 11: The terminal reports the capability of supporting jitter control to the network side through RRC signaling or MAC CE.

[0163] 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 moment within a period of time through a jitter calculation formula.

[0164] The calculation formula for the jitter value or range described here is:

[0165] T 抖动 =T 配置授权所配置的PUSCH传输的第一个上行符号 -T 配置授权的PUSCH实际数据传输的第一个上行符号

[0166] Step 13, the network side configures the jitter reporting threshold to the terminal through RRC signaling. If the jitter value or range of each configuration authorization moment calculated by the above calculation formula exceeds the configured jitter reporting threshold or threshold range, the terminal reports to the network side through MAC CE or UCI that the current configuration authorization has been delayed too much. This threshold reflects that the QoS requirements of the industrial Internet of Things cannot be met due to excessive jitter, or the excessive jitter can be used as a reference for the base station to adjust the physical resource configuration.

[0167] Figure 5 The format of MAC CE is shown. CGi indicates whether the jitter of CGi exceeds the reporting threshold value or threshold range. If the CGi bit is set to 1, it means that the jitter of CGi exceeds the configured threshold value or threshold range. If the CGi bit is set to 0, it means that the jitter of CGi does not exceed the reported configured threshold value or threshold range.

[0168] UCI can use bitmap to directly indicate whether the jitter of CGi exceeds the reporting threshold or threshold range. If the CGi bit is set to 1, it means that the jitter of CGi exceeds the reporting threshold or threshold range. If the CGi bit is set to 0, it means that the jitter of CGi does not exceed the reporting threshold or threshold range.

[0169] Step 14: The terminal reports the jitter value or range to the network side, which may be reported periodically or triggered by the network side or the UE. The terminal reports the jitter value or range that occurs at the current configuration authorization moment to the network side through MAC CE or UCI.

[0170] Figure 6 The format of MAC CE is shown, where CG ID indicates the index number of the uplink configuration authorization. Jitter value indicates the jitter value or range.

[0171] Step 15: The network side senses jitter through the received terminal reported MAC CE or UCI, and optionally reconfigures the configuration authorization.

[0172] Embodiment 2:

[0173] The transmission jitter control method according to an embodiment of the present invention comprises the following steps:

[0174] Step 21: The terminal reports the capability of supporting jitter control to the network side through RRC signaling or MAC CE.

[0175] 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 during the UE registration or access process. Optionally, the network side configures the jitter scheduling group ID and / or code for the terminals in the jitter scheduling group through RRC signaling or MAC CE pairs.

[0176] 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 by the terminal to receive jitter information. The format of the A-RNTI MAC CE is as follows: Figure 7 shown.

[0177] Step 24: The network side obtains the downlink jitter value or value range through measurement or configuration.

[0178] Optionally, the UPF sends the jitter information to the base station via a paging message or an Ng interface message, and the reporter sends the jitter message to the terminal.

[0179] The message may carry at least one of the following information:

[0180] Jitter scheduling group ID and / or code;

[0181] Downlink relative jitter value or value range; the relative reference can be the data arrival time or the expected data arrival time;

[0182] The start symbol and / or start time slot and / or end symbol and / or end time slot of downlink jitter;

[0183] Valid start symbol interval;

[0184] The time and / or period at which downstream jitter takes effect.

[0185] Step 25: The network side sends a paging message or other common RRC message to the UEs belonging to the same jitter scheduling group within the coverage area.

[0186] The network side uses A-RNTI to scramble PDCCH, and the PDCCH information indicates the data packet carrying the message. The message may carry at least one of the following information:

[0187] Jitter scheduling group ID and / or code;

[0188] Downlink relative jitter value or value range; the relative reference can be the data arrival time or the expected data arrival time;

[0189] The start symbol and / or start time slot and / or end symbol and / or end time slot of downlink jitter;

[0190] Valid start symbol interval;

[0191] The time and / or period at which downstream jitter takes effect.

[0192] Step 26, UEs belonging to the same jitter scheduling group receive the PDCCH scrambled by the A-RNTI, descramble the PDCCH, obtain the data packet carrying the message indicated by the PDCCH information, and pass the data packet to the upper layer, thereby obtaining the jitter information contained in the data packet. The network side indicates whether the terminal needs to perform jitter compensation based on the jitter message.

[0193] Embodiment 3:

[0194] The transmission jitter control method according to an embodiment of the present invention comprises the following steps:

[0196] Step 32: The network side configures a B-RNTI for the terminal through RRC signaling or MAC CE. The B-RNTI is used by the terminal to receive jitter information. The format of the B-RNTI MAC CE is as follows: Figure 7 shown.

[0197] Step 33: The network side indicates the terminal downlink jitter information through dynamic PDCCH DCI indication or MAC CE. The message uses B-RNTI to scramble the PDCCH DCI or data packet carrying the message.

[0198] The information may contain at least one of the following information:

[0199] Downlink relative jitter value or value range; the relative reference can be the data arrival time or the expected data arrival time

[0200] Downlink jitter start symbol and / or start time slot and / or end symbol and / or end time slot

[0201] Valid start symbol interval;

[0202] The time and / or period at which downstream jitter takes effect.

[0203] Step 34: The terminal side receives the PDCCH DCI or data packet carrying the message scrambled by the B-RNTI, and obtains the downlink jitter information by descrambling the dynamic PDCCH DCI indication or MAC CE indication through the B-RNTI.

[0204] like Figure 8As shown, the terminal re-determines the receiving PDSCH transmission start symbol or the transmission start PDSCH time slot or the PDSCH transmission start PRB index and / or re-determines the duration of receiving PDSCH transmission according to the received downlink jitter information.

[0205] Embodiment 4:

[0206] The transmission jitter control method according to an embodiment of the present invention comprises the following steps:

[0207] Step 41: The terminal reports the capability of supporting jitter control to the network side through RRC signaling or MAC CE.

[0208] Step 42: The network side configures jitter information of Semi-Persistent Scheduling (SPS) through RRC dedicated signaling.

[0209] The information may contain at least one of the following information:

[0210] Downlink relative jitter value or value range; the relative reference can be the data arrival time or the expected data arrival time

[0211] Downlink jitter start symbol and / or start time slot and / or end symbol and / or end time slot

[0212] Valid start symbol interval;

[0213] The time and / or period at which downstream jitter takes effect.

[0214] Step 43, the terminal side receives the jitter information of the semi-persistent scheduling (Semi-Persistent Scheduling, SPS) configured by the RRC dedicated signaling. The terminal redetermines the starting symbol for receiving the semi-persistent scheduling PDSCH transmission or the starting PDSCH time slot for the semi-persistent scheduling transmission or the starting PRBindex for the semi-persistent scheduling PDSCH transmission and / or redetermines the duration of the semi-persistent scheduling PDSCH transmission reception based on the received downlink jitter.
