Description

[Technical Field]

[0001] The present invention relates to the field of communications. [Background technology]

[0002] 3GPP (registered trademark) (3rd Generation Partnership Project) has begun research into the enhancement of Extended Reality (XR) services in Release 18. XR services refer to environments and human-computer interactions that combine all real and virtual worlds created by computer 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 introduction of the above background art is intended to clearly and completely explain the technical solutions of the present invention and to facilitate understanding by those skilled in the art, and these technical solutions described in the background art of the present invention should not be construed as being known to those skilled in the art. Summary of the Invention [Problem to be solved by the invention]

[0004] The inventors have discovered the following: In XR research, several concepts have been introduced, such as PDU sets and PSDBs (PDU-Set Delay Budgets). A PDU set consists of one or more PDUs (Protocol Data Units) that carry a payload of unit information generated by the application layer, such as a frame of business or a video slice. A PSDB is the delay budget of a PDU set or PDU set type (e.g., a PDU set with the same QoS characteristic parameters is considered as a PDU set type), and is semi-static information provided by the core network.

[0005] Assume that a UE (User Equipment) dynamically reports delay information to the network through a BSR (Buffer Status Report). In this case, on the one hand, if the triggering of the BSR is related to uplink data in a logical channel and takes into account the priority of the logical channel, but does not take into account the delay requirement or delay information of the uplink data carried in the logical channel in question, the XR service may exceed its delay requirement before the BSR is triggered to request uplink resources. As a result, the QoS (Quality of Service) requirement of the XR service may not be satisfied or data may be lost, resulting in a poor user experience. On the other hand, the content of the BSR includes an ID or index of a logical channel group (LCG) and a buffer size (i.e., the total amount of data available for all logical channels in at least one logical channel group). As can be seen, currently BSR does not support reporting of delay information and cannot distinguish how much data is buffered for one delay value, so it cannot meet the 3GPP requirements for reporting delay information.

[0006] To solve at least one of the above problems or other similar problems, embodiments of the present invention provide a delay information reporting method and apparatus, which can meet the delay requirements of XR services and ensure the QoS of XR services. [Means for solving the problem]

[0007] According to one aspect of an embodiment of the present invention, there is provided a delay information reporting device configured in a terminal device, the device comprising: A determination unit that determines the remaining time to be reported (also called the first remaining time); and a transmitting unit for transmitting a delay information report to the network device; The delay information report includes the remaining report waiting time.

[0008] According to another aspect of the present invention, there is provided a setting device configured in a network device, the setting device comprising: a setting unit for transmitting setting information to a terminal device; The setting information includes remaining time period information, which is used by the terminal device to determine the remaining time to wait for a report. [Effects of the Invention]

[0009] The advantageous effects of the embodiments of the present invention are at least as follows: According to the embodiments of the present invention, the terminal device determines the remaining waiting time for reporting and triggers a delay information report including the remaining waiting time for reporting in a timely manner, which helps the terminal device to timely send a delay information report to the network device, and also helps the network device to timely allocate appropriate uplink resources for the transmission of the XR service based on the content of the delay information report, which helps to meet the delay requirements of the XR service, thereby guaranteeing the QoS of the XR service and improving the utilization rate of radio resources.

The term "cell" may refer to a base station and / or the area it covers, depending on the context in which the term is used. Unless confusion arises, the terms "cell" and "base station" are interchangeable.

[0019] In embodiments of the present invention, the term "User Equipment" (UE) or "Terminal Equipment" (TE) refers to a device that accesses and receives service from a communication network, for example, via network equipment.

[0023] The MAC (Media Access Control) standard provides the following explanation regarding BSR triggering:

[0024] [Table 1] The MAC standard also provides the following explanation regarding the contents of the BSR:

[0025] [Table 2] In an embodiment of the present invention, a terminal device sends a delay information report to a network device, and the delay information report may be sent using a BSR MAC CE or another MAC CE, and the present invention is not limited thereto.

[0026] In the embodiment of the present invention, the total amount of data available (or buffer size) included in the delay information report still includes the amount of data in the Packet Data Convergence Protocol (PDCP) layer and the Radio Link Control (RLC) layer.

As shown in Figure 1, in a UE, one PDU set for an XR service has an associated PSDB, and the PSDB may be notified to the UE by the core network. The NAS (Non-Access Stratum) layer handles mapping from PDU set types to QoS flows, and the AS (Access Stratum) layer handles mapping from QoS flows to DRBs. The NAS layer may employ one-to-one or many-to-one mapping between PDU set types and QoS flows, and the AS layer may employ one-to-one, many-to-one, or one-to-many mapping between QoS flows and DRBs, but the present invention is not limited thereto. In the network, the core network can configure a PSDB of at least one PDU set (type) of the UE's XR service in the network equipment, for example, a PSDB of a PDU set (type) of the uplink service and / or a PSDB of a PDU set (type) of the downlink service; or the core network can configure a PSDB of a PDU set (type) corresponding to at least one QoS flow of the UE in the network equipment, where the QoS flow may be an uplink QoS flow and / or a downlink QoS flow.

[0028] 2 is a diagram illustrating buffers in a PDCP entity and its corresponding RLC entity. As shown in FIG. 2, in an embodiment of the present invention, a UE may establish at least one XR service, and therefore establish at least one DRB (corresponding to at least one PDCP entity, at least one RLC entity, and at least one LCH). The PDCP entity corresponding to one DRB has a buffer in which data of PDU set 1 to PDU set 4 may be buffered, and the RLC entity corresponding to the DRB / PDCP entity may buffer data of PDU set 4 to PDU set 7, and the DRB / PDCP entity / RLC entity corresponds to one logical channel.

[0029] Hereinafter, embodiments of the present invention will be described in conjunction with the drawings and specific implementation modes.

[0030] In the following explanation, unless it causes confusion, "if..." may be replaced with "when..." or "when...", "remaining time at the PDCP layer" may be replaced with "remaining time at the PDCP layer of the PDU set", "remaining time at the RLC layer" may be replaced with "remaining time at the RLC layer of the PDU set", "amount of data at the PDCP layer" may be replaced with "amount of data at the PDCP layer of the PDU set", and "amount of data at the RLC layer" may be replaced with "amount of data at the RLC layer of the PDU set".

[0031] <Example of the first aspect> In an embodiment of the present invention, a delay information reporting method is provided, which is explained from the terminal device side.

[0032] FIG. 3 is a diagram illustrating a delay information reporting method according to an embodiment of the present invention. As shown in FIG. 3, the method includes the following operations (steps): 301: The terminal device determines the remaining time to wait for the report; and 302: The terminal device sends a delay information report to a network device, and the delay information report includes the report waiting time remaining.

[0033] Note that, although the above-mentioned FIG. 3 is used to exemplify an embodiment of the present invention, the present invention is not limited thereto. For example, some other operations may be added or removed. Those skilled in the art can make appropriate modifications based on the above content without being limited to the above-mentioned FIG. 3.

[0034] According to the above-described embodiment, the terminal device determines the remaining waiting time for reporting and transmits a delay information report including the remaining waiting time for reporting to the network device, which helps the terminal device to transmit the delay information report to the network device in a timely manner, and also helps the network device to timely allocate appropriate uplink resources for the transmission of the XR service based on the content of the delay information report, which helps to satisfy the delay requirements of the XR service, thereby guaranteeing the QoS of the XR service and improving the utilization rate of wireless resources.

[0035] In 301, in some embodiments, the MAC layer of the terminal device can determine the above-mentioned report waiting time remaining based on the remaining time of the PDCP layer and / or the remaining time of the RLC layer.

[0036] In the above embodiment, the remaining time of the PDCP layer can be indicated by the PDCP layer of the terminal device, and the remaining time of the RLC layer can 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. In this way, the MAC layer of the terminal device can determine the above-mentioned remaining time for waiting for a report based on the remaining time of the PDCP layer and / or the remaining time of the RLC layer.

[0037] In the above embodiment, the layer below the PDCP layer is the RLC layer, and the layer below the RLC layer is the MAC layer. In order to facilitate the RLC layer determining the remaining time of the RLC layer and the MAC layer determining the above-mentioned remaining time for waiting for a report, the PDCP layer of the terminal device may further notify the RLC layer of the remaining time of the PDCP layer, and have the RLC layer determine the remaining time of the RLC layer based on the remaining time of the PDCP layer and the buffer time of the RLC layer. The RLC layer may also further notify the MAC layer of the remaining time of the PDCP layer and the remaining time of the RLC layer together.

[0038] 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 in the PDCP layer and / or the remaining time of the RLC layer.

[0039] In some embodiments, the reporting waiting time remaining refers to at least one of the following: The remaining time of the PDCP layer of the terminal device; Remaining time of the RLC layer of the terminal equipment; The minimum of the remaining time of the terminal device's PDCP layer and the remaining time of the terminal device's RLC layer; remaining period indicator or index; The minimum value of the remaining time in the PDCP layer of the terminal device for the PDU set included in the logical channel; and This is the minimum value of the remaining time in the RLC layer of the terminal device for the PDU set included in the logical channel.

[0040] In the above-mentioned embodiment, the remaining time of the PDCP layer of the terminal device may be the PSDB corresponding to the PDU set minus the buffering time of the PDU set at the PDCP layer, and the remaining time of the RLC layer of the terminal device may be the PSDB corresponding to the PDU set minus the buffering time of the PDU set at the PDCP layer and then further minus the buffering time of the PDU set at the RLC layer, or the remaining time of the PDCP layer minus the buffering time of the RLC layer.

[0041] In the above-mentioned embodiments, the remaining period may be set by the network equipment, for example, the network equipment sets at least one remaining period, and one remaining period may be represented by a period range and its corresponding indicator or index, or the remaining period may be predefined, so that the terminal equipment can implicitly indicate the remaining time to report by reporting the indicator or index of the remaining period.

[0042] In the above-mentioned embodiments, the logical channel refers to a logical channel corresponding to the above-mentioned DRB and / or PDCP entity and / or RLC entity, and the logical channel may include data from one PDU set or may include data from multiple PDU sets.

[0043] In some embodiments, the remaining report waiting time may be the minimum value among the remaining times at the PDCP layer of the PDU sets included in the logical channel. For example, if a logical channel includes four PDU sets, PDU set 1 to PDU set 4, and the remaining time at the PDCP layer of PDU set 1 is t1, the remaining time at the PDCP layer of PDU set 2 is t2, the remaining time at the PDCP layer of PDU set 3 is t3, and the remaining time at the PDCP layer of PDU set 4 is t4, the remaining report waiting time may be the minimum value among t1 to t4.

[0044] In some embodiments, the remaining report waiting time may be the minimum value among the remaining times at the RLC layer of the PDU sets included in the logical channel. For example, if a logical channel includes four PDU sets, PDU set 4 to PDU set 7, and the remaining time at the RLC layer of PDU set 4 is t5, the remaining time at the RLC layer of PDU set 5 is t6, the remaining time at the RLC layer of PDU set 6 is t7, and the remaining time at the RLC layer of PDU set 7 is t8, the remaining report waiting time may be the minimum value among t5 to t8.

[0045] In some embodiments, the terminal device may further determine the amount of data waiting to be reported corresponding to the remaining waiting time for reporting, and in such embodiments, the delay information report not only includes the remaining waiting time for reporting, but also the amount of data waiting to be reported.

[0046] 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.

[0047] In the above embodiment, the amount of data in the PDCP layer may be indicated by the PDCP layer of the terminal device, and the amount of data in the RLC layer may be indicated by the RLC layer of the terminal device. For example, the PDCP layer of the terminal device may notify the amount of data in the PDCP layer to the MAC layer, and the RLC layer of the terminal device may notify the amount of data in the RLC layer to the MAC layer. In this way, the MAC layer of the terminal device can determine the amount of data to be reported based on the amount of data in the PDCP layer and / or the amount of data in the RLC layer.

[0048] In some embodiments, the delay information report further includes an indicator or index of the PDU set, i.e., the delay information report includes the remaining time to wait for report, the amount of data to wait for report, and the indicator or index of the PDU set.

[0049] In the above-mentioned embodiment, the remaining report waiting time and the amount of data waiting to be reported may be sorted according to the order of the PDU set's indicator or index from low to high, or according to the order of the PDU set's indicator or index from high to low, and the present invention is not limited thereto.

[0050] In the above-mentioned 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 quantity of the remaining time of the PDCP layer and / or the remaining time of the RLC layer.

[0051] In the above-mentioned embodiments, in some implementation methods, the remaining report waiting time is the remaining time in the PDCP layer and / or the remaining time in the RLC layer of a PDU set whose remaining time in the PDCP layer and / or the remaining time in the RLC layer is less than a first predetermined threshold, and the amount of data waiting 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 in the PDCP layer and / or the remaining time in the RLC layer.

[0052] In the above-mentioned embodiments, in some implementation methods, the remaining report waiting time is the remaining time at the PDCP layer and / or the remaining time at the RLC layer of a PDU set in which the amount of data at the PDCP layer and / or the amount of data at the RLC layer is greater than a second predetermined threshold, and the amount of data waiting to be reported is the amount of data at the PDCP layer and / or the amount of data at the RLC layer corresponding to the remaining time at the PDCP layer and / or the remaining time at the RLC layer.

[0053] In the above-mentioned embodiments, in some implementation methods, the remaining report waiting time is the remaining time at the PDCP layer and / or the remaining time at the RLC layer of a PDU set for which there is data volume at the PDCP layer, and the amount of data waiting to be reported is the amount of data at the PDCP layer and / or the amount of data at the RLC layer corresponding to the remaining time at the PDCP layer and / or the remaining time at the RLC layer.

[0054] The above-mentioned thresholds (values ​​of the first predetermined threshold and the second predetermined threshold) and the first predetermined quantity may be set in advance or may be set by the network device, and the present invention does not limit the values ​​thereof.

[0055] 4 is a diagram showing the MAC CE format of the delay information report in the above embodiment. As shown in FIG. 4, the MAC CE of the delay information report includes an indicator or index of a PDU set, and further includes information on the remaining time waiting for reporting and information on the amount of data waiting to be reported.

[0056] 5 shows another MAC CE format of the delay information report in the above embodiment. As shown in FIG. 5, the MAC CE of the delay information report does not include an indicator or index of a PDU set, but only includes information on the remaining time to be reported and information on the amount of data to be reported.

[0057] 4 and 5, the remaining report waiting time information and the amount of data waiting to be reported may occupy the same number of bits or different numbers of bits, for example, the remaining report waiting time information occupies 3 bits and the amount of data waiting to be reported occupies 5 bits, or the remaining report waiting time information and the amount of data waiting to be reported information occupy 8 bits each.

[0058] In the examples shown in FIGS. 4 and 5, as described above, the remaining report waiting time and the amount of data waiting to be reported may be sorted in order from high to low or low to high according to the indicator or index of the PDU set.

[0059] In the examples shown in Figures 4 and 5, as described above, the amount of data waiting to be reported may be the amount of data of the PDU set corresponding to the currently lowest remaining time of 1 to m1 (m1 is 1 or a positive integer greater than 1, and may be predefined or set by a network device), or the remaining time waiting to be reported and the amount of data waiting to be reported of a PDU set whose remaining time is lower than one threshold, or the remaining time waiting to be reported and the amount of data waiting to be reported of a PDU set whose data amount is higher than one threshold, or the remaining time waiting to be reported and the amount of data waiting to be reported of a PDU set that has data.

[0060] 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 period.

[0061] In the above-mentioned embodiment, as mentioned above, the remaining period may be set by the network equipment, for example, the terminal equipment receives configuration information transmitted by the network equipment, the configuration information including an index of at least one remaining period and its corresponding period range, and the PDCP layer and / or RLC layer of the terminal equipment calculates the sum of the data amount of the PDU set in the at least one remaining period as the data amount to be reported.

[0062] In the above-described embodiment, the remaining period may be predefined as described above. For example, a range of remaining time corresponding to a remaining period indicator or index is predefined. Table 3 is an example of a predefined remaining period, and the present invention is not limited thereto.

[0063] [Table 3] In the above embodiment, the terminal device determines the amount of data corresponding to which remaining period to report based on a predetermined policy or rule, for example, the amount of data corresponding to which remaining period to report based on the amount of data in which remaining period exists. However, the present invention is not limited thereto, and the terminal device can also determine the amount of data corresponding to which remaining period to report based on an instruction from the network device or other conditions.

[0064] For example, the amount of data waiting to be reported may be the amount of data in a PDU set corresponding to a second predetermined amount of remaining time with the lowest (or highest) indicator or index of the remaining time for which data is waiting to be transmitted; or the amount of data in a PDU set for which the lower or upper limit of the remaining time for which data is waiting to be transmitted is lower than a third predetermined threshold; or the amount of data in a PDU set for which the amount of data waiting to be transmitted is higher than a fourth predetermined threshold; or the amount of data in a PDU set corresponding to a third predetermined amount of remaining time with the lowest (or highest) indicator or index of the remaining time; or the amount of data in a PDU set for which the lower or upper limit of the remaining time is lower than a fifth predetermined threshold.

[0065] In some embodiments, the delay information report further includes at least one remaining period indicator or index, i.e., the delay information report includes a remaining time to wait for a report, an amount of data to wait for a report, and at least one remaining period indicator or index.

[0066] In the above-described embodiment, the amount of data to be reported may be the amount of data of at least one PDU set corresponding to at least one remaining period, for example, the amount of data of one PDCP entity; or the amount of data of one RLC entity; or the sum of the amount of data of one PDCP entity and the amount of data of one RLC entity; or the amount of data of multiple PDCP entities; or the amount of data of multiple RLC entities; or the sum of the amount of data of multiple PDCP entities and the amount of data of multiple RLC entities, as long as the remaining time corresponding to these data amounts is within the remaining period.

[0067] The above-mentioned thresholds (the values ​​of the third predetermined threshold to the fifth predetermined threshold) and predetermined quantities (the second predetermined quantity and the third predetermined quantity) may be set in advance or by the network device, and the present invention does not limit their values.

[0068] 6 is a diagram showing the MAC CE format of the delay information report in the above embodiment. As shown in FIG. 6, the MAC CE of the delay information report has a fixed length and includes information on the remaining period and the corresponding amount of data to be reported.

[0069] FIG. 7 illustrates another MAC CE format for the delay information report in the above-described embodiment. As shown in FIG. 7, the MAC CE of the delay information report has a variable length and also includes information on the remaining period and the corresponding amount of data to be reported. The difference from the example shown in FIG. 6 is that a bitmap is used to indicate whether the amount of data corresponding to the remaining period appears. For example, if the MAC CE supports reporting the amount of data for up to eight remaining periods, or if the network device sets the number of remaining periods to not exceed eight, the first byte of the MAC CE is a bitmap, and Ti indicates whether the amount of data corresponding to the remaining period appears (presence or absence). Ti = 1 indicates that the amount of data corresponding to the remaining period will appear later, and Ti = 0 indicates that the amount of data corresponding to the remaining period will not appear later.

[0070] In the examples shown in Figures 6 and 7, the number of bits occupied by the information on the remaining period and the information on the amount of data waiting to be reported may be the same or different, for example, the information on the remaining period may occupy 3 bits and the information on the amount of data waiting to be reported may occupy 5 bits, or the information on the remaining period and the information on the amount of data waiting to be reported may occupy 8 bits each.

[0071] In the examples shown in Figures 6 and 7, as described above, the amount of data waiting to be reported may be the amount of data of a PDU set corresponding to the currently lowest remaining period of 1 to m2 (m2 is 1 or a positive integer greater than 1, and may be predefined or set by the base station), or the amount of data of a PDU set whose upper limit of the remaining period is lower than one threshold, or the amount of data of a PDU set whose data amount is higher than one threshold.

[0072] In an embodiment of the present invention, the trigger for reporting delay information may be at least one of the following conditions, that is, the terminal device can send a delay information report to the network device when at least one of the following conditions is met, and these conditions include but are not limited to: The remaining time of one PDU set at the PDCP layer of the terminal device is lower than the sixth predetermined threshold, or the minimum remaining time of the PDU set at the PDCP layer of the terminal device is lower than the seventh predetermined threshold; The remaining time of one PDU set at the RLC layer of the terminal device is lower than an eighth predetermined threshold, or the minimum remaining time of the PDU set at the RLC layer of the terminal device is lower than a ninth predetermined threshold; The minimum value of the remaining time at the PDCP layer of the terminal device and the remaining time at the RLC layer of the terminal device for one PDU set is lower than a tenth predetermined threshold; There is uplink data arriving, and the uplink data belongs to one logical channel, and the PSDB corresponding to one PDU set included in the logical channel is lower than the PSDB corresponding to the PDU sets included in all other logical channels with data; and The buffering time of one PDU set in the PDCP layer of the terminal device or the buffering time in the RLC layer of the terminal device exceeds an eleventh predetermined threshold.

[0073] The above-mentioned thresholds (the values ​​of the sixth to eleventh predetermined thresholds) are preset or set by the network device, and the present invention does not limit the values ​​thereof.
