Description

Technical Field

[0001] This application relates to, but is not limited to, the field of communications, and particularly to a polling method, a first device, a computer-readable storage medium, and a computer program product. Background Technology

[0002] Currently, in relevant protocols, once the number of unpolluted Protocol Data Units (PDUs) or the count of unpolluted bytes accumulated by the Acknowledge Mode (AM) Radio Link Control (RLC) entity (transmitter) exceeds a preset threshold, it will send a polling request to the receiver to inquire about the data reception status. Upon receiving the polling request from the transmitter, the receiver needs to send a status report back to the transmitter. Here, the receiver can send Status Protocol Data Units (PDUs) containing the status report to its peer AM RLC entity (transmitter). The status report provides confirmation of the correctness and / or incorrectness of RLC Service Data Units (SDUs) or parts thereof. The polling method described above for AM RLC mode is a crucial part of achieving reliable data transmission.

[0003] However, the polling method for RLC AM mode does not take into account the latency-sensitive characteristics of services such as Extended Reality (XR), resulting in inappropriate polling parameter settings and long delays. Consequently, the sending end cannot obtain status reports for latency-sensitive PDUs in a timely manner, and therefore cannot arrange retransmissions for data that has not been correctly received. This leads to the phenomenon that latency-sensitive PDUs time out and are not correctly received, resulting in their being discarded. Summary of the Invention

[0004] This application provides a polling method, a first device, a computer-readable storage medium, and a computer program product.

[0005] The technical solution of this application embodiment is implemented as follows:

[0008] Based on the first information, a polling indication is added to the first confirmation mode data protocol data unit sent to the second device; wherein, the polling indication is used to instruct the second device to provide feedback on the reception status of multiple confirmation mode data protocol data units; the multiple confirmation mode data protocol data units include the first confirmation mode data protocol data unit.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0026] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] Figure 1 This is a flowchart illustrating a polling method provided in an embodiment of this application, as shown below. Figure 1 As shown, the method is applied to a first device configured with enhanced acknowledged mode (AM) radio link control (RLC), and the method includes:

[0029] Step 101: Determine the first piece of information.

[0030] The first piece of information is used to determine one or more of the following: whether the data within a PDU exceeds the latency budget; whether the data within a PDU group exceeds the latency budget; and whether the latency between data streams in a multimodal service exceeds the maximum threshold.

[0031] In this embodiment, the first information is information related to the set polling parameters.

[0032] Here, PDU and PDU group both refer to PDU and PDU group sent by the first device, and the data stream in the multimodal service is the data stream between the first device and the second device or in the multimodal service of the first device.

[0033] Here, the delay budget is used to identify the maximum allowable delay for data transmission. The delay budget can be a packet delay budget (PDB), or a delay budget determined based on the remaining delay time, and can be preset.

[0034] Here, the maximum threshold can be preset or determined based on multimodal services.

[0035] Step 102: Based on the first information, add a polling instruction to the first confirmation mode data protocol data unit sent to the second device.

[0036] The polling instruction is used to instruct the second device to report the reception status of multiple AM ​​data (D) PDUs; the multiple AMD PDUs include the first AMD PDU.

[0037] In this embodiment of the application, the polling indicator is a one-bit indicator that requests a status report containing RLC feedback information (ACK / NACK) from the sending side of the AM RLC entity to the receiving side of the AM RLC entity.

[0038] In this embodiment of the application, the first device is a data transmitting device and the second device is a data receiving device.

[0039] In some embodiments, if the first information satisfies the condition, it is determined that the data within the protocol data unit exceeds the delay budget, and / or the data within the protocol data unit group exceeds the delay budget, and / or the delay between data streams in the multimodal service exceeds the maximum threshold. In this case, a polling event is triggered, and a polling indication is added to the first AMD PDU sent to the second device.

[0040] In some embodiments, if the first information does not meet the conditions, it is determined that the data within the protocol data unit does not exceed the delay budget, and / or the data within the protocol data unit group does not exceed the delay budget, and / or the delay between data streams in the multimodal service does not exceed the maximum threshold, then it is determined that a polling event will not be triggered.

[0041] The above conditions include one or more of the following: the target timer in the first information times out; wherein the target timer is a timer started after the first device enables the latency-sensitive enhancement function; the first information is used to indicate polling; the latency-sensitive state of the first device in the first information changes or is indicated as latency-sensitive; the time state of the first radio link control service data unit in the first information changes or is indicated as latency-sensitive; the remaining time of the first radio link control service data unit in the first information is a preset value or less than a configured threshold value for the remaining time; the count value corresponding to the first counter in the first information reaches a threshold value; wherein the first counter is used to count the number of unpolluted service data units or the number of bytes contained in the unpolluted service data units; the count value corresponding to the second counter in the first information reaches a threshold value; wherein the second counter is used to count the number of unpolluted latency-sensitive service data units or the number of bytes contained in the unpolluted latency-sensitive service data units.

[0042] Here, enabling the latency-sensitive enhancement feature means using the latency-sensitive characteristics of the service as a condition for whether to add a polling indicator.

[0043] In some embodiments, the delay budget can be represented by the duration of a timer.

[0044] In this embodiment, the RLC layer implementation includes a timer-based RLC SDU polling function. The RLC SDU polling function is an action of the RLC transmitter, with each RLC SDU corresponding to a timer. When an RLC SDU is received from an upper layer (such as the application layer or PDCP layer of a communication device), the RLC transmitter starts a timer for that RLC SDU. Once started, the timer runs continuously until it times out. If the timer times out, it indicates that the RLC SDU has exceeded the delay budget within the timer's duration. In this case, the transmitter adds a polling indication to the first AMD PDU sent to the receiver to inquire about the data reception status.

[0045] It should be noted that an RLC PDU can be an AMD PDU or a UMD PDU, but does not include an RLC control PDU; data received from or sent to an upper layer is called an SDU, and data sent to or received from a lower layer is called a PDU. For example, data received from or sent to an upper layer by an RLC entity is called an RLC SDU, and data sent from an RLC entity to a lower-level entity is called an RLC PDU.

[0046] This application provides a polling method, which includes: a first device determining first information; wherein the first information is used to determine one or more of the following: whether the data within a protocol data unit exceeds the delay budget; whether the data within a protocol data unit group exceeds the delay budget; whether the delay between data streams in a multimodal service exceeds a maximum threshold; based on the first information, adding a polling indication to a first acknowledgment mode data protocol data unit sent to a second device; wherein the polling indication is used to instruct the second device to provide feedback on the reception status of multiple acknowledgment mode data protocol data units; the multiple acknowledgment mode data protocol data units include the first acknowledgment mode data protocol data unit. In other words, the polling method provided in this application takes into account the latency-sensitive characteristics of the service, that is, based on the first information, it determines whether the data sent by the first device meets the latency-sensitive requirements. If it does, the first device promptly requests the second device to report the corresponding status report. The first device can obtain the corresponding status report in a timely manner and can promptly arrange retransmission of data that has not been correctly received, so that latency-sensitive data can be correctly received.

[0047] Figure 2 This is a flowchart illustrating a polling method provided in an embodiment of this application, as shown below. Figure 2 As shown, the method is applied to a first device, and the method includes:

[0048] Step 201: Receive a first message including first instruction information.

[0049] The first instruction information is used to instruct the first device to enable the latency-sensitive enhancement function.

[0050] In some embodiments, the first message further includes a plurality of preset latency indication levels and polling parameters corresponding to each latency indication level; based on this, the method provided in this application embodiment includes the following: receiving a first latency indication level corresponding to a first radio link control service data unit; determining polling parameters corresponding to the first radio link control service data unit based on the first latency indication level; wherein, the polling parameters include one or more of the following parameters: configuration parameter M; counter threshold value; preset value of remaining time; threshold value of remaining time; timer value.

[0051] For example, when the RLC AM entity receives an indication from the upper layer (such as an RRC indication), such as an indication to enable latency-sensitive enhancement, it configures multiple latency indication levels and corresponding polling parameters (such as polling parameter 1 corresponding to latency indication level 1). When the RLC AM entity receives an indication from the upper layer (such as a PDCP indication), such as a latency indication level indicating the degree of RLC SDU latency (e.g., 10% of packets reaching a preset threshold), the RLC AM entity selects the corresponding polling parameter according to the latency indication level.

[0052] Step 202: When the first device enables the latency-sensitive enhancement function, receive the first radio link control service data unit.

[0053] Step 203: If the first radio link control service data unit includes one or more of the following information, start the first timer;

[0054] The delay-sensitive data indicator bit of the first radio link control service data unit is set to be delay-sensitive data;

[0055] Remaining time for the first radio link control service data unit;

[0056] The time state or time status of the first radio link control service data unit is indicated as latency sensitive.

[0057] Step 204: Determine the first piece of information.

[0058] The first information is used to determine one or more of the following: whether the data within a protocol data unit exceeds the delay budget; whether the data within a protocol data unit group exceeds the delay budget; and whether the delay between data streams in a multimodal service exceeds the maximum threshold.

[0059] Step 205: If the first information satisfies one or more of the following conditions, determine that the data within the protocol data unit exceeds the delay budget, and / or the data within the protocol data unit group exceeds the delay budget, and / or the delay between data streams in the multimodal service exceeds the maximum threshold, and add a polling indication to the first acknowledgment mode data protocol data unit sent to the second device.

[0060] The first timer in the first message timed out;

[0061] The first message is used to instruct polling to be performed;

[0062] The delay-sensitive state of the first device in the first information has changed or has been indicated as delay-sensitive;

[0063] The time state of the first radio link control service data unit in the first information has changed or has been indicated as latency sensitive;

[0064] The remaining time of the first radio link control service data unit in the first information is a preset value or less than the configured threshold value of the remaining time.

[0065] For example, consider a delay budget scheme for a PDU:

[0066] When the transmitting RLC AM entity receives an indication from the upper layer (such as RRC), for example, enabling a delay-sensitive enhancement indication, a first timer is set for the transmitting RLC AM entity; when the transmitting RLC AM entity receives an RLCSDU from the upper layer (such as PDCP), a first timer is started for the RLC SDU if the RLC SDU carries at least one of the following information:

[0067] The delay-sensitive data indicator bit is set to indicate that the data is delay-sensitive.

[0068] Or, remaining time;

[0069] Alternatively, the data time status or time status is indicated as latency sensitive.

[0070] Among them, "remaining time" represents the remaining time before the SDU is discarded by the higher layer; when the remaining time is 0, it can be understood that the higher layer has discarded the SDU. "Data time status" or "time status" represents the data time status or time status corresponding to the SDU, which includes non-latency sensitive status, latency sensitive status, and timeout status.

[0071] Polling is included in the AMD PDU when at least one of the following conditions is met;

[0072] The first counter has expired;

[0073] Alternatively, it may receive instructions from higher-level authorities (PDCP).

[0074] Alternatively, the time-sensitive state changes or is indicated as time-sensitive;

[0075] Alternatively, the time status changes or it is indicated as latency-sensitive;

[0076] Alternatively, the remaining time can be 0, a preset value, or less than a configured threshold value for the remaining time.

[0077] Here, the AMD PDU mentioned above may be the most recently sent AMD PDU.

[0078] It should be noted that when configuring the value of the first timer and the threshold value of the remaining time, the delay budget of the PDU can be considered.

[0079] It should be noted that the descriptions of the same steps and contents as in other embodiments in this embodiment can be found in the descriptions in other embodiments, and will not be repeated here.

[0080] Figure 3 This is a flowchart illustrating a polling method provided in an embodiment of this application, as shown below. Figure 3 As shown, the method is applied to a first device, and the method includes:

[0081] Step 301: Receive a first message including first instruction information.

[0082] The first instruction information is used to instruct the first device to enable the latency-sensitive enhancement function.

[0083] Step 302: When the first device enables the latency-sensitive enhancement function, receive the first radio link control service data unit.

[0084] Step 303: If the first radio link control service data unit includes one or more of the following information, and the first radio link control service data unit is indicated as the first radio link control service data unit containing the first protocol data unit set, start the second timer.

[0085] The delay-sensitive data indicator bit of the first radio link control service data unit is set to be delay-sensitive data;

[0086] Remaining time for the first radio link control service data unit;

[0087] The time state or time status of the first radio link control service data unit is indicated as latency sensitive.

[0088] Step 304: Determine the first piece of information.

[0089] The first information is used to determine one or more of the following: whether the data within a protocol data unit exceeds the delay budget; whether the data within a protocol data unit group exceeds the delay budget; and whether the delay between data streams in a multimodal service exceeds the maximum threshold.

[0090] Step 305: If the first information satisfies one or more of the following conditions, determine that the data within the protocol data unit exceeds the delay budget, and / or the data within the protocol data unit group exceeds the delay budget, and / or the delay between data streams in the multimodal service exceeds the maximum threshold, and add a polling indication to the first acknowledgment mode data protocol data unit sent to the second device.

[0091] The second timer in the first message timed out;

[0092] The first message is used to instruct polling to be performed;

[0093] The delay-sensitive state of the first device in the first information has changed or has been indicated as delay-sensitive;

[0094] The time state of the first radio link control service data unit in the first information has changed or has been indicated as latency sensitive;

[0095] The remaining time of the first radio link control service data unit in the first information is a preset value or less than the configured threshold value of the remaining time.

[0096] For example, consider a delay budget scheme for a PDU set:

[0097] When the transmitting RLC AM entity receives an indication from the upper layer (such as RRC), for example, enabling delay-sensitive enhancement indication, a second timer is set for the transmitting RLC AM entity; when an RLC SDU is received from the upper layer (such as the PDCP layer), if the RLC SDU carries at least one of the following information at the same time, and the RLC SDU is indicated as the first RLC SDU containing a PDU set, a second timer is started for the transmitting RLC AM entity.

[0098] The latency sensitivity indicator is set to latency-sensitive data;

[0099] Or, remaining time;

[0100] Alternatively, the data time status or time status is indicated as latency sensitive;

[0101] Among them, "remaining time" represents the remaining time before the SDU is discarded by the higher layer; when the remaining time is 0, it can be understood that the higher layer has discarded the SDU. "Data time status" or "time status" represents the data time status or time status corresponding to the SDU, which includes non-latency sensitive status, latency sensitive status, and timeout status.

[0102] Polling is included in the AMD PDU when at least one of the following conditions is met.

[0103] The second timer has expired;

[0104] Alternatively, it may receive instructions from higher-level authorities (PDCP).

[0105] Alternatively, the time-sensitive state changes or is indicated as time-sensitive;

[0106] Alternatively, the data time status may change or it may be indicated as latency-sensitive;

[0107] Alternatively, the remaining time can be 0, a preset value, or less than a configured threshold value for the remaining time.

[0108] Here, the aforementioned AMD PDU may be the most recently sent AMD PDU.

[0109] It should be noted that the value of the second timer can be configured to take into account the delay budget of the PDU set.

[0110] It should be noted that the descriptions of the same steps and contents as in other embodiments in this embodiment can be found in the descriptions in other embodiments, and will not be repeated here.

[0111] Figure 4 This is a flowchart illustrating a polling method provided in an embodiment of this application, as shown below. Figure 4 As shown, the method is applied to a first device, and the method includes:

[0112] Step 401: Receive a first message including first instruction information.

[0113] The first instruction information is used to instruct the first device to enable the latency-sensitive enhancement function.

[0114] Step 402: When the first device enables the latency-sensitive enhancement function, receive the first radio link control service data unit.

[0115] Step 403: If the first radio link control service data unit includes one or more of the following information, and the first radio link control service data unit is indicated to contain a first data stream belonging to the multimodal service, start the third timer.

[0116] The delay-sensitive data indicator bit of the first radio link control service data unit is set to be delay-sensitive data;

[0117] Remaining time for the first radio link control service data unit;

[0118] The time state or time status of the first radio link control service data unit is indicated as latency sensitive.

[0119] Step 404: Determine the first piece of information.

[0120] The first information is used to determine one or more of the following: whether the data within a protocol data unit exceeds the delay budget; whether the data within a protocol data unit group exceeds the delay budget; and whether the delay between data streams in a multimodal service exceeds the maximum threshold.

[0121] Step 405: If the first information satisfies one or more of the following conditions, determine that the data within the protocol data unit exceeds the delay budget, and / or the data within the protocol data unit group exceeds the delay budget, and / or the delay between data streams in the multimodal service exceeds the maximum threshold, and add a polling indication to the first acknowledgment mode data protocol data unit sent to the second device.

[0122] The third timer in the first message timed out;

[0123] The first message is used to instruct polling to be performed;

[0124] The delay-sensitive state of the first device in the first information has changed or has been indicated as delay-sensitive;

[0125] The time state of the first radio link control service data unit in the first information has changed or has been indicated as latency sensitive;

[0126] The remaining time of the first radio link control service data unit in the first information is a preset value or less than the configured threshold value of the remaining time.

[0127] For example, consider a latency scheme between data streams in a multimodal service:

[0128] When the sending RLC AM entity receives an indication from the upper layer (such as RRC), for example, enabling delay-sensitive enhancement indication, a third timer is set for the sending RLC AM entity; when an RLC SDU is received from the upper layer (such as the PDCP layer), if the RLC SDU carries at least one of the following information and the RLC SDU is indicated to belong to a data stream in a multimodal service, a third timer is started for the sending RLC AM entity.

[0129] The latency sensitivity indicator is set to latency-sensitive data;

[0130] Or, remaining time;

[0131] Alternatively, the data time status or time status is indicated as latency sensitive.

[0132] Among them, "remaining time" represents the remaining time before the SDU is discarded by the higher layer; when the remaining time is 0, it can be understood that the higher layer has discarded the SDU. "Data time status" or "time status" represents the data time status or time status corresponding to the SDU, which includes non-latency sensitive status, latency sensitive status, and timeout status.

[0133] Polling is included in the AMD PDU when at least one of the following conditions is met;

[0134] The third timer has expired;

[0135] Alternatively, it may receive instructions from higher-level authorities (PDCP).

[0136] Alternatively, the time-sensitive state changes or is indicated as time-sensitive;

[0137] Alternatively, the time status changes or it is indicated as latency-sensitive;

[0138] Alternatively, the remaining time can be 0, a preset value, or less than a configured threshold value for the remaining time.

[0139] Here, the AMD PDU mentioned above may be the most recently sent AMD PDU.

[0140] It should be noted that the value of the third timer can be configured to take into account the latency between data streams in multimodal services.

[0141] It should be noted that the descriptions of the same steps and contents as in other embodiments in this embodiment can be found in the descriptions in other embodiments, and will not be repeated here.

[0142] Figure 5 This is a flowchart illustrating a polling method provided in an embodiment of this application, as shown below. Figure 5 As shown, the method is applied to a first device, and the method includes:

[0143] Step 501: Receive a first message including first instruction information.

[0144] The first instruction information is used to instruct the first device to enable the latency-sensitive enhancement function.

[0145] In some embodiments, the first message further includes a plurality of preset latency indication levels and polling parameters corresponding to each latency indication level; the method provided in this application embodiment includes the following: receiving a first latency indication level corresponding to a first radio link control service data unit; determining polling parameters corresponding to the first radio link control service data unit based on the first latency indication level; wherein, the polling parameters include one or more of the following parameters: configuration parameter M; counter threshold value; preset value of remaining time; threshold value of remaining time; timer value.

[0146] Step 502: When the first device enables the latency-sensitive enhancement function, receive the first radio link control service data unit.

[0147] Step 503: Determine the count quantity corresponding to the first counter and the count quantity corresponding to the second counter.

[0148] The first counter is used to count the number of unpolled service data units or the number of bytes contained in an unpolled service data unit.

[0149] The second counter is used to count the number of unpolled latency-sensitive service data units or the number of bytes contained in an unpolled latency-sensitive service data unit.

[0150] In some embodiments, if a first radio link control service data unit is received, the first counter is incremented by one; if the received first radio link control service data unit is indicated to be delay-sensitive, both the first counter and the second counter are incremented by one; if the configuration parameter is M and the received first radio link control service data unit is indicated to be delay-sensitive, the first counter is incremented by one and the second counter is incremented by M; M is a positive integer.

[0151] In some embodiments, if the number of bytes received in the first radio link control service data unit is N, the first counter is incremented by N.

[0152] If the number of bytes received for the first Radio Link Control Service Data Unit is N, and the first Radio Link Control Service Data Unit is indicated to be latency-sensitive, increment the first counter by N, and increment the second counter by N.

[0153] If the configuration parameter is M, and the number of bytes received from the first radio link control service data unit is N, and the first radio link control service data unit is indicated as latency sensitive, increment the first counter by N, and increment the second counter by T; where T is M multiplied by N; and N is a positive integer.

[0154] Step 504: Determine the first piece of information.

[0155] The first information is used to determine one or more of the following: whether the data within a protocol data unit exceeds the delay budget; whether the data within a protocol data unit group exceeds the delay budget; and whether the delay between data streams in a multimodal service exceeds the maximum threshold.

[0156] Here, the first information represents the magnitude of the count value corresponding to the first counter and the threshold value, and / or the magnitude of the count value corresponding to the second counter and the threshold value.

[0157] Step 505: If the first information satisfies one or more of the following conditions, determine that the data within the protocol data unit exceeds the delay budget, and / or the data within the protocol data unit group exceeds the delay budget, and / or the delay between data streams in the multimodal service exceeds the maximum threshold, and add a polling indication to the first acknowledgment mode data protocol data unit sent to the second device.

[0158] The count value corresponding to the first counter in the first information has reached the threshold value;

[0159] The count value corresponding to the second counter in the first message has reached the threshold value.

[0160] For example, when the sending RLC AM entity receives an indication from the upper layer (such as RRC), such as enabling a delay-sensitive enhancement indication.

[0161] Counting Statistics: When an RLC SDU is received from an upper layer (such as the PDCP layer), the first counter of the RLC AM entity increments by 1. When an RLC SDU is received from an upper layer (such as the PDCP layer) and is simultaneously indicated as delay-sensitive, the first counter of the RLC AM entity increments by 1, and the second counter increments by 1. Here, the second counter is used to count delay-sensitive SDUs. If the higher layer configures parameter M (the increment step of the delay-sensitive RLC SDU counter), when an RLCSDU is received from an upper layer (such as the PDCP layer) and is simultaneously indicated as delay-sensitive, the first counter of the RLC AM entity increments by M, and the second counter increments by 1. M can be understood as a counting step specifically designed for delay-sensitive RLC SDUs.

[0162] Byte Count Statistics: When an RLC SDU is received from an upper layer (such as the PDCP layer) and its byte size is N, the first counter of the RLC AM entity is incremented by N. When an RLC SDU is received from an upper layer (such as the PDCP layer) and is simultaneously indicated as latency-sensitive, and its byte size is N, the first counter of the RLC AM entity is incremented by N, and the second counter is incremented by N. Here, the second counter is used to count latency-sensitive SDUs. If the higher layer is configured with parameter M, when an RLC SDU is received from an upper layer (such as the PDCP layer) and is simultaneously indicated as latency-sensitive, and its byte size is N, the first counter of the RLC AM entity is incremented by N, and the second counter is incremented by M*N. M can be understood as a counting step specifically designed for latency-sensitive RLC SDUs.

[0163] It should be noted that when the first counter reaches the first threshold and / or the second counter reaches the second threshold, the first threshold / second threshold can be configured by a higher layer and polled in the most recently sent AMD PDU.
