Description

Method and device for reporting delayed information Technical Field

[0001] The embodiments of the present application relate to the field of communication technologies. Background Art

[0002] In Release 18, the 3rd Generation Partnership Project (3GPP) began researching enhancements to Extended Reality (XR) services. XR services refer to all combined real and virtual environments and human-computer interactions enabled by computing technology and wearable devices. XR services can include Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR).

[0003] It should be noted that the above technical background is merely provided to provide a clear and complete description of the technical solutions of this application and to facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0004] Summary of the Invention

[0005] The inventors discovered that some concepts were introduced in XR research, such as PDU set (PDU group or PDU set) and PSDB (PDU-Set Delay Budget). A PDU set consists of one or more PDUs (Protocol Data Units) that carry a payload of a unit of information generated by the application layer, such as a frame of service or a video slice. PSDB is the delay budget of a PDU set or a PDU set type (for example, a PDU set with the same QoS characteristic parameters is considered a PDU set type), which is semi-static information provided by the core network.

[0006] Assuming that the UE (User Equipment) dynamically reports delay information to the network via a BSR (Buffer Status Report), the triggering of the BSR is related to the uplink data in the logical channel. This considers the priority of the logical channel, but not the latency requirements or delay information of the uplink data carried by the logical channel. This can lead to XR services exceeding their latency requirements before a BSR is triggered to request uplink resources. This can result in unmet QoS (Quality of Service) requirements for the XR service or data loss, degrading the user experience. Furthermore, the BSR content includes the identifier or index of the Logical Channel Group (LCG) and the buffer size (i.e., the total amount of data available for all logical channels in at least one logical channel group). Currently, the BSR does not support reporting delay information and cannot distinguish how much data is buffered for a given delay value. Therefore, it fails to meet the 3GPP requirements for delay information reporting.

[0007] In response to at least one of the above problems or other similar problems, embodiments of the present application provide a method and apparatus for reporting delay information to meet the latency requirements of XR services, thereby ensuring the QoS of XR services.

[0008] According to one aspect of an embodiment of the present application, there is provided an apparatus for reporting delay information, which is configured in a terminal device, and includes:

[0009] A determination unit, which determines the remaining time to be reported;

[0010] A sending unit is configured to send a delay information report to a network device, wherein the delay information report includes the remaining time to be reported.

[0011] According to another aspect of an embodiment of the present application, a configuration device is provided, configured on a network device, the device comprising:

[0012] A configuration unit sends configuration information to a terminal device, wherein the configuration information includes remaining time period information, and the remaining time period information is used by the terminal device to determine the remaining time to be reported.

[0013] One of the beneficial effects of the embodiments of the present application is that: according to the embodiments of the present application, the terminal device determines the remaining time to be reported, and promptly triggers a delay information report containing the remaining time to be reported, which helps the terminal device to send a delay information report to the network device in a timely manner. In addition, the network device can promptly allocate appropriate uplink resources for the transmission of XR services based on the content of the delay information report, which is conducive to meeting the delay requirements of the XR service, thereby ensuring the QoS of the XR service, and also improving the utilization of wireless resources.

[0052] Embodiments of the first aspect

[0053] An embodiment of the present application provides a method for reporting delay information, which is described from the perspective of a terminal device.

[0054] FIG3 is a schematic diagram of a method for reporting delay information according to an embodiment of the present application. As shown in FIG3 , the method includes:

[0055] 301: The terminal device determines the remaining time to be reported;

[0056] 302: The terminal device sends a delay information report to the network device, where the delay information report includes the remaining time to be reported.

[0057] It is worth noting that FIG3 above only schematically illustrates an embodiment of the present application, and the present application is not limited thereto. For example, other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above content, and are not limited to the description of FIG3 above.

[0058] According to the above embodiment, the terminal device determines the remaining time to be reported and sends a delay information report including the remaining time to be reported to the network device, which helps the terminal device to send the delay information report to the network device in a timely manner. In addition, the network device can allocate appropriate uplink resources for the transmission of XR services in a timely manner according to the content of the delay information report, which is conducive to meeting the delay requirements of the XR service, thereby ensuring the QoS of the XR service, and also improving the utilization of wireless resources.

[0059] In 301, in some embodiments, the MAC layer of the terminal device determines the remaining time to be reported based on the remaining time of the PDCP layer and / or the remaining time of the RLC layer.

[0060] In the above embodiment, the remaining time of the PDCP layer may be indicated by the PDCP layer of the terminal device, and the remaining time of the RLC layer may be indicated by the RLC layer of the terminal device. For example, the PDCP layer of the terminal device notifies the MAC layer of the remaining time of the PDCP layer, and the RLC layer of the terminal device notifies the MAC layer of the remaining time of the RLC layer. Thus, the MAC layer of the terminal device can determine the remaining time to be reported based on the remaining time of the PDCP layer and / or the remaining time of the RLC layer.

[0061] In the above embodiment, the lower layer of the PDCP layer is the RLC layer, and the lower layer of the RLC layer is the MAC layer. In order to facilitate the RLC layer to determine the remaining time of the RLC layer and facilitate the MAC layer to determine the above-mentioned remaining time to be reported, the PDCP layer of the terminal device can also notify the RLC layer of the remaining time of the PDCP layer, and the RLC layer determines the remaining time of the RLC layer based on the remaining time of the PDCP layer and the cache time of the RLC layer. In addition, the RLC layer can also notify the MAC layer of the remaining time of the PDCP layer and the remaining time of the RLC layer.

[0062] In the above embodiment, the remaining time of the PDCP layer and / or the remaining time of the RLC layer may be the remaining time of the PDU set at the PDCP layer and / or the remaining time of the RLC layer.

[0063] In some embodiments, the remaining time to be reported is at least one of the following:

[0064] The remaining time of the PDCP layer of the terminal device;

[0065] The remaining time of the RLC layer of the terminal device;

[0066] The minimum value of the remaining time of the PDCP layer of the terminal device and the remaining time of the RLC layer of the terminal device;

[0067] The identifier or index of the remaining time period;

[0068] The minimum value of the PDU set included in the logical channel in the remaining time of the PDCP layer of the terminal device;

[0069] The minimum value of the PDU set included in the logical channel in the remaining time of the RLC layer of the terminal device.

[0070] In the above embodiment, the remaining time of the PDCP layer of the terminal device can be the PSDB corresponding to the PDU set minus the time when the PDU set is cached in the PDCP layer; the remaining time of the RLC layer of the terminal device can be the PSDB corresponding to the PDU set minus the time when the PDU set is cached in the PDCP layer, minus the cache time of the PDU set in the RLC layer, or the remaining time of the PDCP layer minus the cache time of the RLC layer.

[0071] In the above embodiment, the remaining time period can be configured by the network device, for example, the network device configures at least one remaining time period, and a remaining time period is characterized by the range of the time period and its corresponding identifier or index, or the remaining time period can be predefined, whereby the terminal device implicitly indicates the remaining time to be reported by reporting the identifier or index of the remaining time period.

[0072] In the above embodiment, the logical channel refers to the logical channel corresponding to the above DRB and / or PDCP entity and / or RLC entity. The logical channel may include data from one PDU set or data from more than one PDU set.

[0073] In some embodiments, the remaining time to be reported may be the minimum value among the remaining times of the PDU sets included in the logical channel at the PDCP layer. For example, a logical channel includes four PDU sets, namely PDU set 1 to PDU set 4, where the remaining time of PDU set 1 at the PDCP layer is t1, the remaining time of PDU set 2 at the PDCP layer is t2, the remaining time of PDU set 3 at the PDCP layer is t3, and the remaining time of PDU set 4 at the PDCP layer is t4. In this case, the remaining time to be reported may be the minimum value among t1 to t4.

[0074] In some embodiments, the remaining time to be reported may also be the minimum value among the remaining times of the PDU sets included in the logical channel at the RLC layer. For example, a logical channel includes four PDU sets, namely PDU set 4 to PDU set 7, where the remaining time of PDU set 4 at the RLC layer is t5, the remaining time of PDU set 5 at the RLC layer is t6, the remaining time of PDU set 6 at the RLC layer is t7, and the remaining time of PDU set 7 at the RLC layer is t8. Then, the remaining time to be reported may be the minimum value among t5 to t8.

[0075] In some embodiments, the terminal device may also determine the amount of data to be reported corresponding to the remaining time to be reported. In this embodiment, the delay information report includes not only the remaining time to be reported, but also the amount of data to be reported.

[0076] In some embodiments, the MAC layer of the terminal device may determine the amount of data to be reported based on the data volume of the PDCP layer and / or the data volume of the RLC layer.

[0077] In the above embodiment, the amount of data at the PDCP layer may be indicated by the PDCP layer of the terminal device, and the amount of data at the RLC layer may be indicated by the RLC layer of the terminal device. For example, the PDCP layer of the terminal device notifies the MAC layer of the amount of data at the PDCP layer, and the RLC layer of the terminal device notifies the MAC layer of the amount of data at the RLC layer. Thus, the MAC layer of the terminal device can determine the amount of data to be reported based on the amount of data at the PDCP layer and / or the amount of data at the RLC layer.

[0078] In some embodiments, the delay information report further includes an identifier or index of the PDU set. That is, the delay information report includes the remaining time to be reported, the amount of data to be reported, and the identifier or index of the PDU set.

[0079] In the above embodiment, the remaining time to be reported and the amount of data to be reported can be sorted in descending order according to the identifier or index of the PDU set, or can be sorted in descending order according to the identifier or index of the PDU set. This application does not impose any restrictions on this.

[0080] In the above embodiment, in some implementations, the amount of data to be reported is: the amount of data in the PDU set corresponding to the lowest first predetermined amount of remaining time in the remaining time of the PDCP layer and / or the remaining time of the RLC layer.

[0081] In the above embodiments, in some implementation methods, the remaining time to be reported is: the remaining time of the PDCP layer and / or the remaining time of the RLC layer is lower than the remaining time of the PDCP layer of the PDU set with a first predetermined threshold and / or the remaining time of the RLC layer; the amount of data to be reported is: the amount of data in the PDCP layer and / or the amount of data in the RLC layer corresponding to the remaining time of the PDCP layer and / or the remaining time of the RLC layer.

[0082] In the above embodiments, in some implementation methods, the remaining time to be reported is: the remaining time of the PDCP layer and / or the remaining time of the RLC layer of the PDU set in which the data volume of the PDCP layer and / or the data volume of the RLC layer is higher than the second predetermined threshold; the amount of data to be reported is: the data volume of the PDCP layer and / or the data volume of the RLC layer corresponding to the remaining time of the PDCP layer and / or the remaining time of the RLC layer.

[0083] In the above embodiments, in some implementation methods, the remaining time to be reported is the remaining time of the PDCP layer and / or the remaining time of the RLC layer of the PDU set with data volume in the PDCP layer; the amount of data to be reported is the amount of data in the PDCP layer and / or the amount of data in the RLC layer corresponding to the remaining time of the PDCP layer and / or the remaining time of the RLC layer.

[0084] The above threshold values ​​(the values ​​of the first predetermined threshold and the second predetermined threshold) and the first predetermined number can be pre-set or configured by the network device, and this application does not impose any restrictions on their values.

[0085] Figure 4 is a schematic diagram of the MAC CE format of the delay information report in the above embodiment. As shown in Figure 4, the MAC CE of the delay information report includes an identifier or index of the PDU set. In addition, the MAC CE of the delay information report also includes information on the remaining time to be reported and information on the amount of data to be reported.

[0086] Figure 5 is another schematic diagram of the MAC CE format of the delay information report in the above embodiment. As shown in Figure 5, the MAC CE of the delay information report does not include the identifier or index of the PDU set, but only includes information on the remaining time to be reported and the amount of data to be reported.

[0087] In the examples of Figures 4 and 5, the number of bits occupied by the information on the remaining time to be reported and the information on the amount of data to be reported may be the same or different. For example, the information on the remaining time to be reported occupies 3 bits and the information on the amount of data to be reported occupies 5 bits; or, the information on the remaining time to be reported and the information on the amount of data to be reported each occupy 8 bits, and so on.

[0088] In the examples of FIG. 4 and FIG. 5 , as described above, the remaining time to be reported and the amount of data to be reported may be sorted in order from high to low or from low to high according to the identifier or index of the PDU set.

[0089] In the examples of Figures 4 and 5, as mentioned above, the amount of data to be reported can be the data amount of the PDU set corresponding to the current lowest 1 to m1 remaining times (m1 can be a positive integer of 1 or greater than 1, and can be predefined or configured by the network device), or it can be the remaining time to be reported and the amount of data to be reported of a PDU set whose remaining time is lower than a threshold, or the remaining time to be reported and the amount of data to be reported of a PDU set whose data amount is higher than a threshold, or the remaining time to be reported and the amount of data to be reported of a PDU set with data, and so on.

[0090] In some embodiments, the amount of data to be reported is the amount of data of at least one PDU set corresponding to at least one remaining time period.

[0091] In the above embodiment, as mentioned above, the remaining time period can be configured by the network device. For example, the terminal device receives the configuration information sent by the network device, and the configuration information includes the index of at least one remaining time period and its corresponding time period range. The PDCP layer and / or RLC layer of the terminal device calculates the sum of the data volume of the PDU set in the at least one remaining time period as the data volume to be reported.

[0092] In the above embodiment, as described above, the remaining time period may also be predefined. For example, the remaining time range corresponding to the identifier or index of the predefined remaining time period may be defined. Table 1 is an example of a predefined remaining time period, and the present application is not limited thereto.

[0093] Remaining time period index Remaining time T 00ms≤T<2ms 12ms≤T<5ms 25ms≤T<10ms 310ms≤T<20ms 420ms≤T<50ms

[0094] 550ms≤T<100ms6100ms≤T<200ms7200ms≤T

[0095] Table 1

[0096] In the above embodiment, the terminal device may determine which remaining time period to report the corresponding data volume according to a predetermined policy or rule. For example, the terminal device may determine which remaining time period to report the corresponding data volume according to which remaining time period has data. The present application is not limited thereto. The terminal device may also determine which remaining time period to report the corresponding data volume according to an instruction from a network device or other conditions.

[0097] For example, the amount of data to be reported may be: the amount of data of the PDU set corresponding to the second predetermined number of remaining time periods with the lowest (or highest) identification or index of the remaining time periods with data to be sent; or, the amount of data of the PDU set whose lower limit or upper limit of the remaining time period with data to be sent is lower than the third predetermined threshold; or, the amount of data of the PDU set whose amount of data to be sent is higher than the fourth predetermined threshold; or, the amount of data of the PDU set corresponding to the third predetermined number of remaining time periods with the lowest (or highest) identification or index of the remaining time periods; or, the amount of data of the PDU set whose lower limit or upper limit of the remaining time period is lower than the fifth predetermined threshold.

[0098] In some embodiments, the delay information report further includes an identifier or index of at least one remaining time period. That is, the delay information report includes the remaining time to be reported, the amount of data to be reported, and an identifier or index of at least one remaining time period.

[0099] In the above embodiment, the amount of data to be reported can be the data amount of at least one PDU set corresponding to at least one remaining time period, for example, the data amount of a PDCP entity; or, the data amount of an RLC entity; or, the sum of the data amount of a PDCP entity and the data amount of an RLC entity; or, the data amount of more than one PDCP entity; or, the data amount of more than one RLC entity; or, the sum of the data amount of more than one PDCP entity and the data amount of more than one RLC entity, as long as the remaining time corresponding to these data amounts is within the remaining time period.

[0100] The above threshold values ​​(values ​​of the third predetermined threshold to the fifth predetermined threshold) and predetermined quantities (the second predetermined quantity and the third predetermined quantity) can be pre-set or configured by the network device, and this application does not limit their values.

[0101] FIG6 is a schematic diagram of the MAC CE format of the delay information report of the above embodiment. As shown in FIG6 , the MAC CE of the delay information report may be of fixed length, including information of the remaining time period and its corresponding information of the amount of data to be reported.

[0102] FIG7 is another schematic diagram of the MAC CE format for delay information reporting in the above embodiment. As shown in FIG7 , the MAC CE for delay information reporting can be of variable length and also includes information about the remaining time period and its corresponding amount of data to be reported. Unlike the example in FIG6 , a bitmap is used to indicate whether the amount of data corresponding to the remaining time period appears. For example, if the MAC CE supports reporting the amount of data for up to 8 remaining time periods, or if the network device is configured with no more than 8 remaining time periods, the first byte of the MAC CE is a bitmap, and Ti is an indicator of whether the amount of data corresponding to the remaining time period appears. If Ti = 1, it indicates that the amount of data corresponding to the remaining time period appears later.
