[0098] I. Uplink Authorization (UL grant)

[0099] A UL grant is an uplink resource authorization configured by a network device for a terminal, used to instruct the terminal when, where, and how to send uplink data. A UL grant typically contains the following key information: (1) time-frequency resource allocation information, used to instruct the terminal on the time-domain and frequency-domain resources for uplink transmission; (2) modulation and coding scheme information, used to instruct the terminal on the modulation scheme and coding rate used; (3) transport block size information, used to instruct the terminal on the amount of data that can be sent; and (4) power control information, used to modulate the terminal's transmit power.

[0100] II. LCP

[0101] After receiving the UL grant, the terminal needs to allocate these resources according to the LCP mechanism. LCP is a mechanism used by the terminal to determine the data transmission order when there is data to be sent in multiple logical channels.

[0102] In some embodiments, the network device sends logical channel (LCH) configuration information to the terminal. The LCH configuration information is used to configure the relevant parameters of LCP, and the terminal executes LCP according to the relevant parameters. The relevant parameters of the LCP process include at least one of the following: priority, prioritized bit rate (PBR), and bucket size duration (BSD).

[0103] In some embodiments, the network device may assign a priority to each LCH, with a smaller priority value indicating a higher priority.

[0104] In some embodiments, the network device may configure a PBR for each LCH. The PBR can be understood as the minimum guaranteed rate for each logical channel, which is used to ensure that the LCH can transmit at least the amount of data defined by the PBR under resource constraints.

[0105] In some embodiments, the network device can configure a BSD for each LCH. The BSD can be understood as the depth of the token bucket, which determines the upper limit of the PBR accumulation. The maximum capacity of the token bucket is PBR × BSD.

[0106] In some embodiments, the LCP process includes two rounds of LCP. In the first round, the terminal allocates resources based on the LCH priority and PBR. In the second round, the terminal allocates remaining resources based on the LCH priority. Specifically, in the first round of LCP, the terminal traverses all LCHs from highest to lowest priority, allocating the data amount corresponding to the PBR of each LCH. The allocated data amount does not exceed the data amount in its buffer and the token bucket capacity, and then the token bucket is updated. In the second round of LCP, if there are remaining resources, the terminal allocates the remaining resources to each LCH in order from highest to lowest priority until resources are exhausted or data transmission of all LCHs is completed. The second round of LCP does not limit the PBR, allowing higher-priority LCHs to occupy more resources.

[0107] In some embodiments of multimedia services, such as extended reality (XR) services, there are typically multiple data streams. These streams need to meet certain latency requirements during transmission, especially since some streams need to arrive at the server simultaneously for decoding. A delay in any one stream can cause the joint decoding of multiple streams to fail. However, network scheduling is dynamic. If a data packet has not been scheduled for a long time—for example, a low-priority LCH packet—it needs to send a buffer status report (BSR) to notify the network to schedule it as soon as possible. However, currently only high-priority LCH packets can send a BSR, which fails to meet the urgent scheduling needs of low-priority LCH packets.

[0108] In some embodiments, a delay status reporting (DSR) mechanism can be introduced to address the need for urgent scheduling of low-priority LCH packets.

[0109] 3. DSR

[0110] DSR (Delay Critical Data Response) is a mechanism by which terminals report the status of Delay Critical Data in their buffers to the network side. Its purpose is to optimize network scheduling strategies to meet the demands of low-latency services. DSR provides network devices with the delay status of logical channel groups, including their shortest remaining time and the amount of data associated with the reported remaining time. Network devices control DSR operation using a remaining time threshold.

[0111] In some embodiments, the shortest remaining time is the shortest remaining time for all data packets in the logical channel group, i.e., the time from the current time to the time the data packet is dropped.

[0112] In some embodiments, the amount of data associated with the remaining time can be understood as the amount of buffered data, that is, the amount of buffered data in the logical channel group where the remaining time is less than the remaining time threshold.

[0113] In some embodiments, delayed critical data can be understood as data whose remaining duration is less than a remaining time threshold.

[0114] In some embodiments, delayed critical data can be replaced with emergency data, emergency dispatch data, etc.

[0115] In some embodiments, to address the need for urgent scheduling of low-priority LCH packets, the LCP can be further enhanced by adjusting the LCH priority based on LCH latency information or latency status. In some embodiments, if the LCH contains latency-critical data, the terminal can use additional priority configured for the LCH.

[0116] In some embodiments, the priority configured for the LCH by network devices in an LCP can be understood as the default priority. In some embodiments, the additional priority configured for the LCH by network devices in an enhanced LCP differs from the default priority. In some embodiments, the level of the additional priority is higher than the default priority.

[0117] In some embodiments, the terminal needs to temporarily increase the priority of the LCH under specific conditions, such as when it detects that there is delayed critical data in the LCH. For example, the terminal allocates resources to the LCH with extra priority.

[0118] In some embodiments, additional priority applies to the first and second rounds of the LCP process.

[0119] In some embodiments, after an terminal allocates resources to an LCH using an additional priority, it can fallback the priority of that LCH to its default priority.

[0120] In some embodiments, after the terminal allocates resources to the LCH using the extra priority, the priority of the LCH may not revert to the default priority, that is, the extra priority of the LCH may continue to be used.

[0121] In some embodiments, the LCP process described above is completely executed by the terminal and is unknown to the network device. Therefore, how the network device and the terminal can reach a consensus on the LCP process is an urgent problem to be solved.

[0122] In some embodiments, since the LCP process is performed entirely by the terminal, how the network device determines whether the allocated uplink transmission resources are sufficient and how to adjust the uplink transmission resources allocated in the next iteration are problems that urgently need to be solved.

[0123] This disclosure provides a communication method, communication device, communication system, storage medium, and program product. A terminal can send first information to a network device, indicating the uplink data transmission status. This uplink data transmission status is used by the network device to configure uplink transmission resources for the terminal. In this way, the network device and the terminal can reach a consensus on the uplink data transmission status, facilitating the network device to allocate uplink transmission resources for the next transmission based on the previous uplink data transmission status, thus improving the data transmission performance of the communication system.

[0124] Figure 2 is an interactive schematic diagram of a communication method provided according to an embodiment of the present disclosure. As shown in Figure 2, the present disclosure relates to a communication method. Executed by a communication system 100, the communication method includes steps S2101 to S2104.

In some embodiments, the second information indicates that the terminal supports the execution of the LCP transmission process. In some embodiments, the second information indicates that the terminal does not support the execution of the LCP transmission process.

[0131] In some embodiments, the second information indicates the terminal's ability to support LCH priority changes during LCP transmission. In some embodiments, the second information indicates that the terminal supports LCH priority changes during LCP transmission. In some embodiments, the second information indicates that the terminal does not support LCH priority changes during LCP transmission.

[0132] In some embodiments, the priority change of LCH may include at least one of the following: (1) whether the priority of LCH has been changed; (2) the number of times the priority of LCH has been changed; (3) whether the priority of LCH has been reverted to the default priority after the priority has been changed; (4) the number of LCHs whose priority has been changed; and (5) the number of LCHs whose priority has been reverted to the default priority after the priority has been changed.

[0133] In some embodiments, the second information indicates the terminal's ability to support the transmission rate of uplink data of the LCH during LCP transmission. In some embodiments, the second information indicates that the terminal supports the transmission rate of uplink data of the LCH during LCP transmission. In some embodiments, the second information indicates that the terminal does not support the transmission rate of uplink data of the LCH during LCP transmission.

In some embodiments, the second information indicates that the terminal supports the scheduling of uplink data of the LCH during LCP transmission. In some embodiments, the second information indicates that the terminal does not support the scheduling of uplink data of the LCH during LCP transmission.

[0135] In some embodiments, the uplink data scheduling status includes at least one of the following: (1) whether the uplink data has been scheduled; (2) whether the uplink data has been scheduled during the first round of LCP; (3) whether the uplink data has been scheduled during the second round of LCP; (4) the size of the uplink data that has not been scheduled; and (5) the number of LCHs for which the uplink data has not been scheduled.

[0136] In some embodiments, the second information indicates the terminal's ability to support queuing of uplink data within the transmit buffer. In some embodiments, the second information indicates that the terminal supports queuing of uplink data within the transmit buffer. In some embodiments, the second information indicates that the terminal does not support queuing of uplink data within the transmit buffer.

[0137] In some embodiments, the queuing status of uplink data in the cache includes at least one of the following: (1) whether there is first uplink data in the cache that is placed before second uplink data; (2) the size of the first uplink data placed before second uplink data in the cache; (3) whether the cache contains first uplink data.

In some embodiments, the first threshold is a remaining time threshold configured by the network device, which is used by the terminal to determine the urgency of data scheduling. In some embodiments, the remaining duration of the first uplink data is greater than the remaining time threshold, i.e., the first uplink data can be understood as non-urgent data, and the remaining duration of the second uplink data is less than the remaining time threshold, i.e., the second uplink data can be understood as urgent data that needs to be scheduled for transmission as soon as possible. Hereinafter, the first uplink data will be referred to as non-urgent data, and the second uplink data will be referred to as urgent data.

[0138] In some embodiments, the second information indicates the terminal's ability to support the reporting of DSRs. In some embodiments, the second information indicates that the terminal supports the reporting of DSRs. In some embodiments, the second information indicates that the terminal does not support the reporting of DSRs. In some embodiments, the reporting of DSRs includes: the buffer reported in the DSR contains both non-urgent and urgent data.

[0139] In some embodiments, urgent data is typically stored in the buffer. The buffer size reported by the terminal in the DSR can be understood as the amount of urgent data, and the terminal reports the buffer size to inform the network device of the amount of urgent data that needs to be scheduled as soon as possible. However, if the buffer contains non-urgent data, the buffer size reported by the terminal actually includes non-urgent data. This leads to an inaccurate reported amount of urgent data, preventing the network device from accurately scheduling urgent data and configuring uplink resources. Therefore, the terminal can report this situation to the network device so that the network device can determine the true amount of urgent data, avoid scheduling errors and resource waste caused by prioritizing non-urgent data, and improve scheduling accuracy and efficiency.

[0140] In some embodiments, the second information indicates the terminal's ability to support packet loss during uplink data transmission.

[0141] In some embodiments, the uplink data transmission status is related to at least one of the following: the execution status of the LCP process, the queuing status of uplink data in the buffer, the reporting status of DSR, and the packet loss status of uplink data. In some embodiments, the uplink data transmission status can be replaced by the uplink data scheduling status or the allocation status of uplink transmission resources.

[0142] In some embodiments, the name of the second information is not limited, and it may be, for example, "UE capability information".

[0143] In some embodiments, the terminal may send the second information to the network device via at least one of radio resource control (RRC) signaling, media access control-control element (MAC CE) signaling, and non-access stratum (NAS) signaling.

[0144] In some embodiments, step S2101 can be omitted. In this case, the network device can determine the second information based on protocol specifications, terminal type, etc.

[0145] In step S2102, the network device sends third information.

[0146] In some embodiments, the terminal receives third information.

[0147] In some embodiments, the third information indicates whether the terminal should send information on the uplink data transmission status. In some embodiments, the third information is used to request the terminal to report the uplink data transmission status.

[0148] In some embodiments, the network device sends third information based on the second information. In some embodiments, if the second information indicates that the terminal supports uplink data transmission, the network device sends the third information, which in turn indicates the uplink data transmission status of the terminal. In some embodiments, if the second information indicates that the terminal does not support uplink data transmission, the network device may not send the third information. In this case, the network device may configure uplink transmission resources for the terminal based on existing (legacy) mechanisms.

[0149] In some embodiments, step S2102 may be omitted. In this case, the terminal may determine whether to execute step S2103 based on its own implementation and protocol specifications.

In the first round of LCP, the priority of LCH1 and LCH2 changes from the default priority to the extra priority.

In the second round of LCP, the remaining portions of the uplink data from LCH2 and LCH3 are scheduled for transmission, while only a portion of the uplink data from LCH4 is scheduled for transmission, with the remaining 3 bits of data not scheduled for transmission.

[0222] In the following, the technical solutions of the embodiments of this disclosure will be described by way of specific implementation.

[0223] In some embodiments, this disclosure provides a method for protecting terminals to report uplink scheduling information to the network to assist the network in scheduling.

[0224] In some embodiments, the terminal can report the situation during the uplink resource allocation process to the network to assist the base station in scheduling.

[0225] In some embodiments, the terminal reports the status of LCP (Local Capability Protocol) operation to the base station.

[0226] In some embodiments, the terminal notifies the network whether an LCH priority change has been performed during the two rounds of LCP execution. In some embodiments, the terminal may notify the base station of a list of logical channels whose priorities have been changed.

[0227] In some embodiments, the terminal can notify the network LCH1 that no priority level change was performed during the two rounds of LCP, at which point the base station can know that its authorization may be insufficient.

[0228] In some embodiments, the terminal notifies the network whether the PBR was satisfied during the first round of LCP execution. In some embodiments, the terminal may notify the base station of a list of logical channels whose PBRs were satisfied;

[0229] In some embodiments, the terminal may notify the network LCH1 that the PBR was satisfied during the first round of LCP execution, at which point the base station may know that its authorization may be insufficient.

[0230] In some embodiments, the terminal notifies the network whether scheduling has been completed during the first or second round of LCP execution.

[0231] In some embodiments, the terminal may notify all logical channels of the network that all data scheduling has been completed during the first round of LCP execution, at which point the base station may know that its authorization may be sufficient.

[0232] In some embodiments, the terminal may notify all logical channels of the network that all data scheduling has not been completed during the second round of LCP execution, at which point the base station may know that its authorization may be insufficient.

[0233] In some embodiments, the terminal notifies the network of the interval at which the logical channel is scheduled during the first or second round of LCP execution.

[0234] In some embodiments, the terminal can statistically analyze the evaluation interval time during which LCH1 is scheduled in the LCP execution process over a period of time, at which point the base station can know whether its authorization is sufficient;

[0235] In some embodiments, the terminal notifies the network of the queuing status of its buffer.

[0236] In some embodiments, the terminal may notify the network whether there is non-urgent data ahead of urgent data in the buffering process, and include some of the data in the buffer size of the urgent data when reporting DSR.

[0237] In some embodiments, the terminal has non-urgent data that is placed before urgent data in the buffer process. When the DSR is reported, some of the data is included in the buffer size of the urgent data. At this time, the base station can know that some non-urgent data is also reported in the DSR report. At this time, its authorization is insufficient because the urgent data has been blocked by the non-urgent data in the buffer.

[0238] In some embodiments, the terminal notifies the network whether packet loss occurs during the uplink scheduling process due to untimely scheduling.

[0239] In some embodiments, the terminal may notify the network that packet loss at the PDCP layer is caused by untimely uplink scheduling.

[0240] In some embodiments, the total number of packets lost at the PDCP layer or the total number of bytes / bits lost.

[0241] In some embodiments, the PDCP layer counts the interval between packet losses.

[0242] In some embodiments, if the terminal frequently experiences PDCP layer packet loss during uplink transmission, the base station can know that its authorization is insufficient.

[0243] In some embodiments, the network instructs the terminal whether to report the information as described above.

[0244] In some embodiments, the terminal notifies the network whether it has the capability to report the aforementioned auxiliary information. In some embodiments, a separate capability indicator can be set for each piece of auxiliary information, or a common general indicator information can be used.

[0245] In some embodiments, this terminal capability is related to existing terminal capabilities. In some embodiments, the prerequisite for a terminal to have the ability to change priority levels or report changes during both rounds of LCP is that the terminal already supports LCP enhancement functionality.

[0246] In some embodiments, the prerequisite for a terminal to have the ability to prioritize non-urgent data over urgent data during the buffering process and to include a portion of this data in the buffer size of the urgent data during DSR reporting is that the terminal already supports DSR reporting.
