Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a wireless communication processing method, related devices, and computer storage media. Background Art

[0002] A user equipment (UE) can support up to 16 hybrid automatic repeat request (HARQ) processes at most. Each HARQ process corresponds to the transmission of a transport block (TB) or a code block group (CBG). The maximum number of HARQ retransmissions is directly configured through the media access control (MAC) layer.

[0003] During the transmission process, the data packet will not stop retransmitting until the retransmission is successful or the retransmission times limit is reached. Currently, completing the retransmission of the current HARQ process according to the maximum number of retransmissions configured by the MAC layer will waste the limited number of HARQ processes, increase unnecessary load on the network, and cause capacity limitation.

[0054] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0055] ST is the timeout for indicating the on / off status of a communication link in industrial control. If the receiving end does not receive a data packet within the ST time, it is considered that there is a problem with the data link, and the production task cannot continue. The result is reported to the Manufacturing Execution System (MES) system, resulting in the production line being shut down.

[0056] In a real-time industrial control process, ST is generally an integer multiple of the cycle time (CT). CT can be understood as the data transmission cycle. In an industrial control network, regardless of whether the status data is updated, the devices subordinate to the Programmable Logic Controller (PLC) continuously send data to the input / output (IO) interface at a fixed cycle, and the PLC polls and reads the latest status data of the IO interface at a fixed cycle. The old data will be overwritten by the new data, and only the latest status data will affect the logical output of the PLC. This function combines data update and heartbeat functions. In some industrial protocols, only the sending and receiving ends continuously send packets unidirectionally to each other and do not reply with an Acknowledge character (ACK) message.

[0057] Such asFigure 1 As shown, for example, a classic configuration in an industrial Ethernet protocol for factory automation (such as the Process FieldNet industrial protocol, abbreviated as the Profinet industrial protocol) is ST = 3×CT, CT = 4ms. When the receiving end receives a data packet within 12ms, it considers the network available, and when receiving the data packet, it will parse the packet sequence number. If it is less than the sequence number of the previous data packet, it is considered old data and will be directly discarded. If no data packet is received within 12ms, it will determine that there is a problem with the current communication link and issue an alarm.

[0058] The UE can support up to 16 HARQ processes at most. Each HARQ process corresponds to the transmission of a TB block or a CBG. The maximum number of HARQ retransmissions is directly configured through the MAC layer, mostly configured according to empirical values and RV versions, without considering the actual situation of the service. During the transmission process, the data packet will not stop retransmitting until the retransmission is successful or the retransmission count limit is reached. Therefore, even if the retransmitted data packet is already useless data for the application layer, the lower layer cannot perceive it and will complete the retransmission of this HARQ process according to the configured maximum number of retransmissions, which will waste the limited number of HARQ processes, add unnecessary load to the network, and lead to capacity limitation.

[0059] In an industrial control network, ST will be configured differently according to the service's requirements for latency and determinism, ranging from a few ms to several hundred ms. According to the ratio of the frame structure, the time for one HARQ is basically in the ms level. In this case, it is possible that during the retransmission of a certain data packet, a new data packet has been sent and successfully received by the industrial service, and the previous data packet has no meaning. Even if the receiving end receives it, it will be directly regarded as useless data and discarded by the peer; or during the retransmission process, when it has reached ST and the application layer has issued an alarm and stopped, the bottom layer of the 5th Generation Mobile Communication Technology (5G) protocol stack cannot perceive it and continues to execute the packet retransmission, but the packet retransmission has no meaning for the service and instead consumes air interface resources.

[0060] This application proposes a method for ST and HARQ coordination. By using the ST index of the service and the current network configuration, the maximum number of HARQ retransmissions that matches the service is obtained and configured to the MAC layer. The MAC layer makes a retransmission count decision based on the configuration and the usage of HARQ processes, making the HARQ process more matched with the service requirements, enhancing the perception and matching between the 5G transmission process and the service, reducing the transmission of meaningless data packets in the air interface, releasing HARQ processes in a timely manner, saving air interface resources and the limited number of HARQ processes, improving the effective utilization rate of resources, thereby improving network capacity and ensuring the transmission and determinism of other services / data packets.

[0061] An embodiment of the present application provides a wireless communication processing method, which is applied to a fourth device, such as Figure 2 shown, and the method includes:

[0062] Step 201: Receive a first message sent by a first device, where the first message includes information related to the survival time ST of a traffic flow.

[0063] In practical applications, the first device may be a core network / service side device, and the first device includes but is not limited to: an Access and Mobility Management Function (AMF) device / a Session Management Function (SMF) device / a network exposure function (NEF) device / an application function (AF) device.

[0064] In practical applications, the fourth device may be an ST and HARQ collaborative decision-making module. To obtain ST-related information, the ST and HARQ collaborative decision-making module can be implemented in any of the following ways:

[0065] Through a service feature interface, the service platform opens the service feature information of ST to the base station, and the base station can directly obtain the ST time through this interface;

[0066] Through a network-service collaborative self-awareness system, self-identify the ST of the service;

[0067] To achieve the adaptation between the network and the service, the core network will obtain service features from the AF according to the service situation and configure the TSC Assistance Information (TSCAI) of the data stream for the base station, where TSC refers to Time Sensitive Communication (TSC), and TSCAI includes the ST time.

[0068] In one embodiment, the fourth device receives a first message sent by the first device, and the first message includes information related to the survival time ST of the traffic flow. In this way, the fourth device can obtain ST-related information from the core network / service side device. It should be noted that the ST and HARQ collaborative decision-making module can be deployed independently of each layer of the protocol stack in the network-service collaborative module, or can be deployed in a fused manner with the functions of each layer of the protocol stack. The present application does not make specific limitations on this.

[0069] Step 202: Receive a second message sent by a second device, where the second message includes information related to the Hybrid Automatic Repeat reQuest (HARQ) process.

[0070] In practical applications, the second device may be a network-side device, such as a network-service collaboration module.

[0071] In one embodiment, the fourth device receives a second message sent by the second device, and the second message includes information related to the HARQ process. In this way, the fourth device can obtain information related to the HARQ process from the network side, such as related parameter configuration information, network quality, and utilization rate of physical resource blocks (PRBs).

[0072] Step 203: Send a third message to the third device, where the third message includes the maximum HARQ retransmission times matching the ST.

[0073] In practical applications, the third device may be a base station-side device, such as a building baseband unit (BBU).

[0074] In one embodiment, the fourth device analyzes and judges according to the first message (corresponding to network configuration) and the second message (corresponding to service ST time), outputs the maximum HARQ retransmission times matching the ST, and configures this parameter for the BBU. Further, this parameter can be configured for the MAC layer of the BBU.

[0075] In one embodiment, after the MAC of the BBU receives the maximum HARQ retransmission times matching the ST, it compares with the current configuration and decides the final maximum retransmission times configured for the data stream according to a given principle.

[0076] The wireless communication processing method provided by this application is applied to the fourth device. The method includes: receiving a first message sent by the first device, where the first message includes ST-related information of the service flow; receiving a second message sent by the second device, where the second message includes information related to the HARQ process; sending a third message to the third device, where the third message includes the maximum HARQ retransmission times matching the ST. It can be seen that this application utilizes the ability of the (Service Data Adaptation Protocol, SDAP) layer to integrate network and service. Through the ST metrics of the service and the current network configuration, it obtains the maximum HARQ retransmission times matching the service, and configures this result for the MAC layer, for the transmission and retransmission of MAC service data packets, making the HARQ process more matched with the service requirements, enhancing the perception and matching of the transmission process and the service in the communication system (such as a 5G communication system), reducing the transmission of meaningless data packets over the air interface, releasing the HARQ process in a timely manner, saving air interface resources and the limited number of HARQ processes, improving the effective utilization rate of resources, thereby improving the network capacity and ensuring the transmission and determinacy of other services / data packets.

[0077] In one embodiment, step 201 receives a first message sent by a first device, including:

[0078] Receiving the first message sent by the first device through a first interface, the interface data format of the first interface includes [QoSFlow_ID / Traffic Flow_ID, ST].

[0079] In practical applications, such as Figure 3 As shown, the fourth device may be an ST and HARQ collaborative decision-making module, the first interface may be the S0 interface of the ST and HARQ collaborative decision-making module, and the S0 interface may be referred to as a service characteristic interface for transmitting service ST information. The interface data format of the S0 interface includes [QoS Flow_ID / Traffic Flow_ID, ST].

[0080] In one embodiment, step 202 receives a second message sent by a second device, including:

[0081] Receiving the second message sent by the second device through a second interface, the interface data format of the second interface includes at least one of the following:

[0082] [Time slot offset K0 from receiving downlink control information DCI on the physical downlink control channel PDCCH to receiving information on the physical downlink shared channel PDSCH, time slot offset K2 from receiving a UL grant on the PDCCH to sending a control instruction ULdata on the PUSCH, list of time slot offset candidates dl-DataToUL-ACK from receiving information on the PDSCH to sending a HARQ ACK / NACK message on the PUCCH to the network side, time length t_slot represented by each time slot];

[0083] [Number of retransmissions N_retrans];

[0084] [Time slot offset K1 between the slot n received by the PDSCH and the PUCCH for HARQ-ACK, reference signal received power RSRP, signal-to-interference-plus-noise ratio SINR, physical resource block utilization uti_PRB].

[0085] In practical applications, such as Figure 3As shown, the fourth device may be an ST and HARQ collaborative decision-making module, and the second interface may be the S1 interface of the ST and HARQ collaborative decision-making module. The S1 interface may be referred to as an interface for transmitting parameters such as transmission network configuration / network status, etc. The S1 interface is used to transmit HARQ-related information. Further, when the S1 interface is used to transmit HARQ-related configuration information, the interface data format is [K0, K1, K2, dl-DataToUL-ACK, N_retrans]; when the S1 interface is used to transmit network configuration-related configuration information, the interface data format is [t_slot]; when the S1 interface is used to transmit network status-related information, the interface data format is [RSRP, SINR, uti_PRB].

[0086] In practical applications, the information related to the HARQ process includes at least one of the following:

[0087] Configuration information related to the radio resource control (RRC) layer and HARQ;

[0088] Configuration information related to the media access control (MAC) layer and HARQ;

[0089] Information related to the physical (PHY) layer of the port, HARQ, and network status.

[0090] In one embodiment, as Figure 4 shown, the S1 interface can also be divided. For example, the S1 interface includes an S11 interface for transmitting configuration information related to the RRC layer and HARQ, and the interface data format is [K0, K2, dl-DataToUL-ACK, t_slot]; the S1 interface includes an S12 interface for transmitting configuration information related to the MAC layer and HARQ, and the interface data format is [N_retrans]; the S1 interface includes an S13 interface for transmitting information related to the PHY layer, HARQ, and network status, and the interface data format is [K1, RSRP, SINR, uti_PRB].

[0091] In one embodiment, the fourth device may be an ST and HARQ collaborative decision-making module. The ST and HARQ collaborative decision-making module obtains information related to HARQ on the base station side, including:

[0092] The RRC layer configures the information related to HARQ retransmission to the ST and HARQ collaborative decision-making module. The message includes K0 (the time slot offset from receiving DCI on the PDCCH to the time slot for receiving information on the PDSCH), dl-DataToUL-ACK (a list of candidate time slot offsets from receiving information on the PDSCH to sending HARQ ACK / NACK messages on the PUCCH to the network side), K2 (the time slot offset from receiving the UL grant on the PDCCH to sending UL data on the PUSCH), and the time slot time t_slot;

[0093] The MAC layer configures the maximum number of HARQ retransmissions N_retrans to the ST and HARQ collaborative decision-making module;

[0094] The PHY layer configures the parameter K1 (the time slot offset between the slot n for receiving on the PDSCH and the PUCCH for HARQ-ACK) to the ST and HARQ collaborative decision-making module. The ST and HARQ collaborative decision-making module jointly analyzes K1 and dl-DataToUL-ACK to obtain the time slot offset delay_datatoUL-ACK from receiving downlink data to feedback ACK / NACK.

[0095] In practical applications, ACK is Acknowledgement, which is a positive feedback. The receiving party sends a message to inform the sending party after receiving the data. NACK is Negative Acknowledgement, which is a negative feedback. The receiving party only notifies the sending party when it does not receive the data.

[0096] In one embodiment, step 203 sends a third message to a third device, including:

[0097] Sending a third message to the third device through a third interface. The interface data format of the third interface includes [QoSFlow_ID / Traffic Flow_ID, N_retrans_ST].

[0098] In practical applications, such as Figure 3 or Figure 4 shown, the fourth device can be the ST and HARQ collaborative decision-making module. The third interface can be the S2 / N2 interface of the ST and HARQ collaborative decision-making module. The S2 / N2 interface can be called the output interface, which is used to transmit the HARQ retransmission times matching the ST. The interface data format is [QoS Flow_ID / Traffic Flow_ID, N_retrans_ST].

[0099] As can be seen from the above, for the wireless communication processing method provided in this application, the service process includes two levels of analysis: one is to analyze the number of HARQ processes matching the ST in the ST and HARQ collaborative decision-making module and input a HARQ process number recommendation to the BBU; the other is to analyze and decide the number of HARQ retransmissions used by the service flow in the MAC layer of the BBU according to the recommendation and the actual situation of HARQ usage.

[0100] In one embodiment, the above wireless communication processing method further includes:

[0101] Obtaining the uplink delay and downlink delay of data transmission;

[0102] Based on the uplink delay, downlink delay, ST-related information, and HARQ process-related information, obtaining the maximum number of HARQ retransmissions matching the ST.

[0103] In actual application, the fourth device can be the ST and HARQ collaborative decision-making module, which statistically analyzes the current network environment, base station load, etc. on the base station side, and estimates the current uplink delay (dalay_uplink) and downlink delay (dalay_downlink) of data transmission through the ST and HARQ collaborative decision-making module.

[0104] Among them, dalay_uplink refers to the one-way delay from the 5G terminal to the base station, and dalay_downlink refers to the one-way delay from the base station to the 5G terminal.

[0105] In actual application, the ST and HARQ collaborative decision-making module calculates the maximum number of retransmissions N_retrans_ST that best matches the service within the range allowed by the ST through the parameters obtained at each layer of the protocol stack.

[0106] In actual application, for the downlink data transmission packet, by considering the data reception time (PDCCH monitoring DCI to PDSCH reception time and the time from PDSCH reception to PUCCH transmission) + transmission delay (downlink data transmission + uplink ACK feedback delay), calculate the maximum value N_retrans_ST_downlink:

[0107] N_retrans_ST_downlink = ceiling(ST / ((K0 + delay_datatoUL - ACK) × t_slot + dalay_uplink + dalay_downlink))

[0108] In actual application, for the uplink data transmission packet, by considering the uplink data authorization waiting time (the time delay from receiving the UL grant on the PDCCH to sending the UL data on the PUSCH) + the transmission delay (the uplink data transmission delay), calculate the maximum value N_retrans_ST_uplink:

[0109] N_retrans_ST_uplink = ceiling(ST / (K2 × t_slot + dalay_uplink)).

[0110] In actual application, the coordination module configures the maximum retransmission times N_retrans_ST_downlink and N_retrans_ST_uplink for the MAC layer for both uplink and downlink.

[0111] The embodiment of the present application provides a wireless communication processing method, which is applied to a third device, such as Figure 5 as shown, and the method includes:

[0112] Step 501: Receive a third message sent by a fourth device, where the third message includes the maximum HARQ retransmission times matching the ST.

[0113] In actual application, the third device can be a base station side device, such as a BBU. The MAC of the BBU receives the third message sent by the fourth device, and the third message includes the maximum HARQ retransmission times matching the ST. In this way, for a service flow, the MAC will obtain the default configured N_retrans for the HARQ process from the MAC layer and the N_retrans_ST configured by the coordination module, and obtain the maximum retransmission times N_retrans_HARQ_ID of the HARQ process where the service flow is located based on N_retrans and N_retrans_ST.

[0114] The wireless communication processing method provided by the present application is applied to a third device. The method includes: receiving a third message sent by a fourth device, where the third message includes the maximum HARQ retransmission times matching the ST. It can be seen that the present application utilizes the ability of the SDAP layer network to integrate with services, obtains the maximum HARQ retransmission times matching the service through the ST index of the service and the current network configuration, and configures the result for the MAC layer. The MAC decides the transmission and retransmission of service data packets, making the HARQ process more matching the service requirements, enhancing the perception and matching of the transmission process and the service in the communication system (such as a 5G communication system), reducing the transmission of meaningless data packets in the air interface, timely releasing the HARQ process, saving the air interface resources and the limited number of HARQ processes, improving the effective utilization rate of resources, thereby improving the network capacity and ensuring the transmission and certainty of other services / data packets.

[0115] In one embodiment, after step 501 receives a third message sent by a fourth device, where the third message includes the maximum HARQ retransmission times matching the ST, the above wireless communication processing method further includes:

[0116] Obtain the maximum HARQ retransmission times matching the traffic flow based on the maximum HARQ retransmission times matching the ST;

[0117] Configure the maximum HARQ retransmission times matching the traffic flow to the corresponding HARQ process, so that the HARQ process performs data transmission according to the maximum HARQ retransmission times matching the traffic flow.

[0118] In practical applications, the third device may be a base station side device, such as a BBU. Here, the BBU obtains the maximum HARQ retransmission times matching the traffic flow based on the maximum HARQ retransmission times matching the ST. It can be that the MAC obtains, for a traffic flow, the N_retrans configured by the MAC layer for the default HARQ process and the N_retrans_ST configured by the coordination module, and obtains the maximum retransmission times N_retrans_HARQ_ID of the HARQ process where the traffic flow is located by comparing N_retrans and N_retrans_ST.

[0119] In one embodiment, the obtaining the maximum HARQ retransmission times matching the traffic flow based on the maximum HARQ retransmission times matching the ST includes:

[0120] If the maximum HARQ retransmission times matching the ST is greater than the maximum retransmission times configured by the MAC layer for the HARQ process, obtain the thresholds of the HARQ process usage times and retransmission times;

[0121] Obtain the maximum HARQ retransmission times matching the traffic flow based on the thresholds of the HARQ process usage times and retransmission times.

[0122] In practical applications, if N_retrans_ST > N_retrans, the BBU counts the current HARQ process usage situation N_numofHARQ and the threshold N_numofHARQ_thre for appropriately expanding the retransmission times set by the system through the MAC scheduler. Further, based on N_numofHARQ and N_numofHARQ_thre, N_retrans_HARQ_ID is obtained.

[0123] In one embodiment, obtaining the maximum HARQ retransmission times matching the service flow based on the threshold of the number of HARQ process usages and the number of retransmissions includes: if the number of HARQ process usages is greater than the threshold of the number of retransmissions, the maximum HARQ retransmission times matching the service flow is the maximum retransmission times configured by the MAC layer for the HARQ process;

[0124] In practical applications, if N_numofHARQ > N_numofHAARQ_thre, then

[0125] N_retrans_HARQ_ID = N_retrans.

[0126] If the number of HARQ process usages is less than or equal to the threshold of the number of retransmissions, the maximum HARQ retransmission times matching the service flow is obtained based on the number of HARQ process usages, the threshold of the number of retransmissions, the maximum retransmission times configured by the MAC layer for the HARQ process, and the maximum HARQ retransmission times matching the ST.

[0127] In practical applications, if N_numofHARQ ≤ N_numofHAARQ_thre, then

[0128] N_retrans_HARQ_ID = N_retrans + [(N_numofHARQ_thre - N_numofHARQ) / (N_retrans_ST - N_retrans)] (rounded down).

[0129] In one embodiment, if the maximum HARQ retransmission times matching the ST is less than or equal to the maximum retransmission times configured by the MAC layer for the HARQ process, the maximum HARQ retransmission times matching the service flow is the maximum HARQ retransmission times matching the ST.

[0130] If the BBU determines that N_retrans_ST ≤ N_retrans, then N_retrans_HARQ_ID = N_retrans_ST.

[0131] In one embodiment, the MAC layer configures the maximum retransmission times N_retrans_HARQ_ID matching the service to the corresponding HARQ process. The HARQ process performs data transmission according to the configuration, and after reaching the maximum retransmission times, flips the New Data Indicator (NDI) to end the current HARQ process.

[0132] An embodiment of the present application provides a wireless communication processing method, as Figure 6 shown, the method includes:

[0133] Step 601: The ST and HARQ cooperative decision-making module obtains the ST information of the transmission service.

[0134] Step 602: The ST and HARQ cooperative decision-making module obtains the parameters related to HARQ on the base station side.

[0135] In practical applications, the parameters related to HARQ are obtained on the base station side, including: (1) The RRC layer configures the information related to HARQ retransmission to the ST and HARQ cooperative decision-making module. The message includes K0 (K0 refers to the time slot offset from receiving DCI on the PDCCH to receiving information on the PDSCH), dl-DataToUL-ACK (dl-DataToUL-ACK refers to the list of candidate time slot offsets from receiving information on the PDSCH to sending HARQ ACK / NACK messages on the PUCCH to the network side), K2 (K2 refers to the time slot offset from receiving the UL grant on the PDCCH to sending UL data on the PUSCH), and the time slot time t_slot. (2) The MAC layer configures the maximum retransmission times N_retrans of HARQ to the ST and HARQ cooperative decision-making module. (3) The PHY layer configures the parameter K1 (K1 refers to the time slot offset between the slot n receiving the PDSCH and the PUCCH for HARQ-ACK) to the ST and HARQ cooperative decision-making module. The ST and HARQ cooperative decision-making module jointly analyzes K1 and dl-DataToUL-ACK to obtain the time slot offset delay_datatoUL-ACK from receiving downlink data to feedback ACK / NACK.

[0136] Step 603: The ST and HARQ cooperative decision-making module outputs a recommended maximum retransmission times through analysis and decision-making.

[0137] In practical applications, the current network environment, base station load, etc. are statistically analyzed on the base station side. The uplink and downlink delays dalay_uplink (the one-way delay from the 5G terminal to the base station) and dalay_downlink (the one-way delay from the base station to the 5G terminal) of the current data transmission are estimated through the ST and HARQ cooperative decision-making module. The ST and HARQ cooperative decision-making module calculates the maximum retransmission times N_retrans_ST that best matches the service within the range allowed by the ST through the parameters obtained from each layer of the protocol stack.

[0138] Step 604: The ST and HARQ cooperative decision-making module configures the maximum retransmission times that match the ST to the MAC layer.

[0139] Step 605: The MAC outputs the final configuration through analysis and comparison and applies it to the transmission of each HARQ process.

[0140] The wireless communication processing method provided by this application has at least the following improvement points: adding an ST and HARQ collaborative decision-making module and defining relevant input and output parameters and data formats; combining HARQ-related configurations and service ST situations to define a method for the new module to decide the HARQ retransmission times that match the service; adding methods and processes for the MAC layer to select and determine the HARQ retransmission times; adding an interface for the ST and HARQ collaborative decision-making module. Through the ST metrics of the service and the current network configuration, this application obtains the maximum HARQ retransmission times that match the service, and configures this result to the MAC layer. The MAC layer makes retransmission times decisions based on the configuration and the usage of the HARQ process, making the HARQ process more matched with the service requirements, enhancing the perception and matching between the 5G transmission process and the service, reducing the transmission of meaningless data packets over the air interface, releasing the HARQ process in a timely manner, saving air interface resources and the limited number of HARQ processes, improving the effective utilization rate of resources, thereby improving network capacity, ensuring the transmission and determinacy of other services / data packets, and enhancing the mutual perception and cooperation between the service and the network.
