Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a time-sensitive communication configuration method and a communication system. Background Art

[0002] Time Sensitive Communication (TSC) is a communication method that requires very high latency and timeliness of communication, and is often used in application scenarios that require real-time, timely response and processing. In order to meet the needs of time-sensitive communication, the core network can send time-sensitive service-related characteristics (such as flow direction, burst arrival time, maximum burst size, periodicity, lifetime, etc.) to the base station through time-sensitive communication auxiliary information (TSC Assistance Information, TSCAI), so that the base station can reserve communication resources for related deterministic services through configuration authorization, semi-static scheduling, dynamic authorization, etc. When time-sensitive data packets arrive, they no longer need to be scheduled, thereby reducing waiting time and meeting latency requirements.

[0003] In order to provide different service qualities for different services, the Radio Access Network (RAN) provides QoS (Quality of Service). QoS management is a control mechanism for wireless networks to meet different service quality requirements. 5G protocol uses 5QI (5G QoS Identifier) ​​to identify different service priorities. According to standard TS23.501, the 5G QoS model is mainly based on QoS flow, which supports two types of QoS flows, one is the QoS flow with guaranteed bit rate (GBR), and the other is the QoS flow without guaranteed bit rate (Non-GBR).

[0004] In the current standard, the base station can only obtain time-sensitive information, period, burst arrival time, lifetime and other parameters with guaranteed bit rate from the core network through time-sensitive communication auxiliary information. Considering that services such as extended reality need to support QoS flows without guaranteed bit rate, and need to consider characteristics such as service jitter and non-integer service cycle, the existing 3GPP (3rd Generation Partnership Project) 5G protocol can no longer meet application requirements, and the base station cannot provide more reasonable resource scheduling to achieve time-sensitive communication.

[0005] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0101] S2, the base station feeds back a PDU session resource modification response message to the AMF network element in the core network.

[0102] It should be noted that the first configuration information and the second configuration information in the PDU session resource modification scenario are the same as the first configuration information and the second configuration information in the PDU session resource establishment scenario, and the contents of the PDU session resource modification response message and the PDU session resource establishment response message are also the same, which will not be elaborated here.

[0103] As an optional implementation, the base station may also receive first auxiliary information sent by the terminal, wherein the first auxiliary information includes at least one of the following: uplink PDU set delay overhead, uplink PDU set error rate, uplink PDU set comprehensive processing indication, uplink PDU set importance indication, uplink service cycle, uplink service jitter, and uplink PDU set dynamic parameters.

[0106] Considering that the wireless link layer transmission is mainly based on a single PDU rather than a PDU set, the base station needs to convert the PDU set related parameters in the configuration information obtained from the core network and the auxiliary information obtained from the terminal into PDU related parameters.

[0107] As an optional implementation, the base station may first receive the fourth configuration information sent by the core network, wherein the fourth configuration information includes at least one of the following: a PDU set encoding and decoding method for deriving the data packet error rate from the PDU set error rate, and a downlink PDU set dynamic parameter.

[0109] The dynamic parameters of the downlink PDU set include at least one of the following: downlink PDU set size, downlink PDU set sequence number, PDU sequence number within the downlink PDU set, indication of the end PDU of the downlink PDU set, downlink PDU set importance indication, and burst data end indication.

[0110] Figure 5 It is a schematic diagram of communication between a base station and a terminal, which specifically includes the following steps:

[0111] S1, the base station sends radio resource control (RRC) signaling reconfiguration information (RRC Reconfiguration) to the terminal;

[0112] S2: The terminal feeds back first auxiliary information to the base station.

[0113] Afterwards, the base station may derive the PDU set related parameters in the first configuration information, the second configuration information, the third configuration information, and the fourth configuration information as PDU related parameters.

[0114] Optionally, the derivation includes at least one of the following: deriving a data packet error rate from a PDU aggregate error rate, and deriving a data packet delay budget from a PDU aggregate delay overhead.

[0115] After obtaining all the above information, the base station can perform reasonable resource scheduling configuration for the uplink and / or downlink to meet the needs of time-sensitive communication services.

[0116] As an optional implementation manner, the base station sends a radio resource control signaling including resource configuration information to the terminal, wherein the resource configuration information includes at least one of the following: uplink configuration information and downlink configuration information.

[0119] Finally, the terminal may determine the priority level for receiving or discarding each PDU in the downlink service according to the downlink configuration information, and receive or discard each PDU according to the priority level.

[0120] For example, for downlink services, the terminal prioritizes receiving and / or discards the corresponding PDU in the event of link congestion based on parameters such as the downlink PDU aggregate delay overhead, downlink PDU aggregate importance indication, downlink service data packet error rate, and data packet delay budget in the downlink link configuration information.

[0121] Optionally, the terminal may determine the priority level of performing an uplink operation on each PDU in the uplink service according to the uplink configuration information, and uplink each PDU according to the priority level.

[0122] For example, for uplink services, the terminal may give priority to sending relevant uplink data packets based on parameters such as pre-configured authorization resources, uplink service data packet error rate, and uplink PDU aggregate delay overhead in the uplink configuration information.

[0123] In the present application scheme, the base station can obtain both time-sensitive communication related parameters with a guaranteed bit rate and time-sensitive communication related parameters without a guaranteed bit rate from the core network. At the same time, the base station can also obtain uplink time-sensitive communication related parameters from the terminal. Afterwards, the base station can combine the time-sensitive communication related parameters obtained from the core network and the terminal to more reasonably schedule and allocate resources for time-sensitive communication services, thereby realizing time-sensitive communication transmission.

After deriving the PDU set related parameters into PDU related parameters, the corresponding uplink configuration information and / or downlink configuration information can be determined to perform reasonable resource scheduling configuration for the uplink and / or downlink.

[0134] Optionally, the terminal may determine the priority level for performing a receiving or discarding operation on each PDU in the downlink service according to the downlink configuration information, and receive or discard each PDU according to the priority level.

[0135] For example, for downlink services, the terminal prioritizes receiving and / or discards the corresponding PDU in the event of link congestion based on parameters such as the downlink PDU aggregate delay overhead, downlink PDU aggregate importance indication, downlink service data packet error rate, and data packet delay budget in the downlink link configuration information.
