[0020] The embodiments of the present disclosure provide an information processing method, a terminal, and a storage medium.

[0021] In a first aspect, an embodiment of the present disclosure proposes an information processing method, including: a terminal determines a first operation of canceling DSR.

[0022] In the above embodiment, the terminal may implement the first operation of canceling the DSR to be sent (or triggered).

[0023] In combination with some embodiments of the first aspect, in some embodiments, determining to cancel the first operation of DSR includes: determining to cancel the first operation of DSR based on discarding a high-layer data packet.

[0024] In the above embodiment, when the terminal discards the high-layer data packet, the DSR to be sent (or triggered) does not need to be sent. For example, by canceling the sending of the DSR to be sent (or triggered), unnecessary resources can be saved.

[0025] In combination with some embodiments of the first aspect, in some embodiments, the higher layer includes at least one of the following: a Packet Data Convergence Protocol (PDCP) layer; and a Radio Link Control Protocol (RLC) layer.

[0026] In the above embodiments, the PDCP layer can perform statistics on the data, and / or the PDCP layer can send part of the data to the RLC layer so that the RLC layer can perform statistics on the data; in this way, data packet loss can be detected by the PDCP layer and / or the RLC layer, thereby realizing packet loss detection of data by multiple entities of the terminal.

[0027] In combination with some embodiments of the first aspect, in some embodiments, the first operation of canceling the delayed status report DSR includes at least one of the following: canceling the sending of the DSR; canceling the sending of the scheduling request (SR); and canceling the random access channel (RACH) process.

[0028] In the above embodiment, the cancellation of DSR sending, the cancellation of SR sending and / or the cancellation of RACH process can be achieved by the terminal, thereby saving the waste of necessary resources.

[0029] In combination with some embodiments of the first aspect, in some embodiments, the first operation of canceling the delayed status report DSR includes at least one of the following: canceling the sending of SR when canceling the sending of DSR; and canceling the RACH process when canceling the sending of DSR.

[0030] In the above embodiment, the SR and / or RACH process can be canceled when the DSR is canceled by the terminal. In this way, after the DSR is canceled, it is unnecessary to send the SR triggered by the failure to send the DSR and / or it is unnecessary to trigger the RACH process triggered by the failure to send the SR, thereby saving unnecessary waste of resources.

[0031] In combination with some embodiments of the first aspect, in some embodiments, the method further includes: stopping the SR prohibition timer when canceling the sending of the SR; and / or stopping the DSR associated timer when canceling the sending of the DSR.

[0032] In the above embodiment, the terminal can stop the SR timer when canceling the SR, so that there is no need to resend the SR based on the SR timer when the SR sending fails, thereby saving system resources; and / or, it can stop the DSR-associated timer when canceling the DSR, such as there is no need to run the DSR-associated timer when the DSR is canceled, which can save system resources.

[0033] In combination with some embodiments of the first aspect, in some embodiments, the method further includes: determining that a high-layer data packet is discarded.

[0034] In the above embodiment, the terminal can detect whether a data packet is discarded through a higher layer.

[0035] In combination with some embodiments of the first aspect, in some embodiments, determining that a high-layer data packet is discarded includes: determining that a high-layer data packet is discarded based on an inter-layer message; wherein the inter-layer message is sent to the MAC layer via the high layer.

[0036] In the above embodiment, the terminal can detect through a higher layer and inform the MAC layer of the discard of the data packet, so that the terminal can cancel the sending of the DSR to be sent.

[0037] In combination with some embodiments of the first aspect, in some embodiments, the inter-layer message is sent after a higher-layer data packet is discarded.

[0038] In the above embodiment, after the high layer loses the packet, the terminal can send an inter-layer message to the MAC layer through the high layer, so that the high layer can promptly notify the MAC layer of the discard of the data packet.

[0039] In combination with some embodiments of the first aspect, in some embodiments, determining that high-level data is discarded includes at least one of the following: detecting through the MAC layer that the pending data or first characteristic data of a specific logical channel is discarded; detecting through the MAC layer that the pending data or first characteristic data of a specific logical channel group is discarded.

[0040] In the above embodiment, the terminal can detect the discard of high-layer data through the MAC layer, thereby providing more ways to detect data discard.

[0041] In combination with some embodiments of the first aspect, in some embodiments, based on the discard of high-layer data packets, determining to cancel the first operation of DSR includes: determining based on the protocol that the logical channel corresponding to the high layer enables the function of discarding data packets, and canceling the first operation of DSR when the discard of high-layer data packets is detected.

[0042] In the above embodiment, when the terminal determines that the logical channel enables the function of discarding data packets, it performs the first operation of DSR when detecting that the high layer discards the data packet, so that the operation of canceling the DSR and / or SR and / or RACH process can be implemented for the specific logical channel that is enabled to discard data packets.

[0043] In a second aspect, an embodiment of the present disclosure proposes a terminal, including: a processing module configured to determine a first operation of canceling DSR.

[0044] In a third aspect, an embodiment of the present disclosure proposes a terminal, comprising: one or more processors; wherein the terminal is used to execute the optional implementation method of the first aspect.

[0045] In a fourth aspect, an embodiment of the present disclosure proposes a storage medium, which stores instructions. When the instructions are executed on a communication device, the communication device executes the method described in the optional implementation of the first aspect.

[0046] In a fifth aspect, an embodiment of the present disclosure proposes a program product. When the program product is executed by a communication device, the communication device executes the method described in the optional implementation manner of the first aspect.

[0047] In a sixth aspect, an embodiment of the present disclosure proposes a computer program, which, when executed on a computer, enables the computer to execute the information processing method as described in the optional implementation manner of the first aspect.

[0081] The embodiments of the present disclosure may be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G New Radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future Generation Radio Access (FX), Global System for Mobile Communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.17 (WiMAX (registered trademark)), IEEE 802.18 (WiMAX (registered trademark)), IEEE 802.19 (WiMAX (registered trademark)), IEEE 802.20 (WiMAX (registered trademark)), IEEE 802.21 (WiMAX (registered trademark)), IEEE 802.22 (WiMAX (registered trademark)), IEEE 802.23 (WiMAX (registered trademark)), IEEE 802.24 (WiMAX (registered trademark)), IEEE 802.25 (WiMAX (registered trademark)), IEEE 802.26 (WiMAX (registered trademark)), IEEE 802.27 (WiMAX (registered trademark)), IEEE 802.28 (WiMAX (registered trademark)), IEEE 802.29 (WiMAX (registered trademark)), IEEE 802.30 (WiMAX (registered trademark)), IEEE 802.31 (WiMAX (registered trademark)), IEEE 802.32 (WiMAX (registered trademark)), IEEE 802.33 (WiMAX (registered trademark)), 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0082] In some embodiments, in Extended Reality (XR) services, data usually has multiple data streams, and its business volume is very large. The XR data stream needs to meet certain delay requirements during transmission, especially some data streams need to arrive at the server for decoding at the same time. The delay of any one of the data streams will cause the joint decoding of multiple data streams to fail. However, the scheduling of network devices is dynamic; therefore, in some cases, even if some data streams belong to low-priority logical channels, if some data packets have not been scheduled for a long time, a buffer status report (BSR) needs to be sent to notify the network device as soon as possible. However, at present, BSR can only be sent when high-priority logical channel data arrives, which cannot meet the needs of emergency scheduling. Therefore, it is necessary to consider optimizing the emergency scheduling situation in XR.

[0083] In some embodiments, a DSR report is introduced. Optionally, the terminal reports a DSR that carries latency information; the latency information may be that a data packet has been unscheduled for an extended period, resulting in the remaining time of the data packet being less than a certain threshold. Optionally, the remaining time of the data packet is the time until the packet is discarded, i.e., the remaining time is determined based on the discard timer of the Packet Data Convergence Protocol (PDCP). Optionally, the threshold may be a remaining time threshold.

[0084] In some embodiments, the terminal supports threshold-based DSR reporting. For example, when the remaining time of a Protocol Data Unit (PDU) or PDU set is less than a threshold configured by the network (NW), a DSR report is triggered. Optionally, the threshold is set for each Logical Channel Group (LCG).

[0085] In some embodiments, a Delay Status Report (DSR) procedure is used to provide a delay status for uplink (UL) data to a serving base station (eNB). The DSR includes a remaining time for the UL data; the remaining time is determined based on the duration of a PDCP discard timer associated with the first symbol of a Physical Uplink Shared Channel (PUSCH) transmission in which the DSR is sent, and the amount of data for which the remaining time is reported.

[0086] In some embodiments, RRC controls the DSR operation by configuring a remaining time threshold; the remaining time threshold is a remaining time threshold of UL data configured by the LCG to trigger DSR.

[0087] In some embodiments, the MAC entity triggers the sending of a DSR when the remaining time of a PDU or a set of PDUs in the LCG (if configured for DSR) becomes shorter than its associated remaining time threshold.

[0088] In some embodiments, DSR reporting is unnecessary due to packet loss at the PDCP layer. For example, suppose a newly arrived data packet on a logical channel cannot be scheduled in a timely manner, triggering a DSR. However, due to a discard timer expiration, the data is discarded in bulk at the PDCP layer, making the triggered DSR unnecessary. For example, if the network deactivates DSR reporting, then a triggered DSR is also unnecessary. Therefore, a mechanism for canceling a triggered DSR is necessary.

[0089] FIG2 is an interactive diagram of an information processing method according to an embodiment of the present disclosure. As shown in FIG2 , the present disclosure embodiment relates to an information processing method for an information processing system 100, and the method includes:

[0090] Step S2101: The terminal determines that a high-layer data packet is discarded.

[0098] Optionally, the packet discard may be a situation where the packet is dropped from existence to disappearance in a higher layer.

[0099] Optionally, the name of the inter-layer message is not limited, and it may be, for example, packet loss indication information.

[0100] Optionally, the inter-layer message is sent after a high-layer data packet is discarded. Exemplarily, after a high-layer data packet is lost, the terminal sends the inter-layer message to the MAC layer via the high-layer.

[0104] In step S2102, the terminal determines to cancel the first operation of DSR.

[0105] Optionally, the DSR includes data size and / or time information of the first characteristic data. Exemplarily, the first characteristic data is a subset of data to be transmitted on the terminal; or, the first characteristic data is a subset of data to be transmitted on a logical channel or logical channel group; or, the first characteristic data is a portion of the data to be transmitted. Exemplarily, the time information indicates the time until the data to be transmitted is discarded.

[0106] In some embodiments, the terminal determines to cancel the first operation of DSR based on discarding of a higher layer data packet. Optionally, the terminal determines to cancel the first operation of DSR upon detecting discarding of higher layer data.

[0185] The present disclosure relates to an information processing method, which includes:

[0186] In some embodiments, the terminal cancels the triggered DSR and / or SR and / or RACH operations upon detecting that a higher layer data packet is discarded.

[0187] Optionally, the operation of determining the triggered DSR and / or SR and / or RACH may be the first operation of canceling DSR in the previous embodiment.

[0188] Optionally, when the terminal detects the presence of a specific data packet or data packet set in a logical channel (LC) or logical channel group (LCG) and determines that the remaining time of the specific data packet or data packet set is less than a predetermined threshold, it reports a DSR.

[0193] Optionally, the upper layer may send an inter-layer message to the MAC layer to notify the MAC layer of all data to be transmitted or the change in the presence of the first characteristic data. Exemplarily, the upper layer may send an inter-layer message to the MAC layer to notify the MAC layer of all data to be transmitted or the change in the presence of the first characteristic data on the logical channel. Optionally, the logical channel may be a specific logical channel.

[0194] Optionally, after the PDCP layer performs batch packet discarding of data packets, it sends an inter-layer message to the MAC layer to notify the logical channel of all data to be transmitted or the change of the first characteristic data from presence to absence.

[0195] Optionally, the MAC layer detects that the amount of all data or first characteristic data transmitted for the logical channel or logical channel group becomes 0.

[0197] Optionally, when uplink (UL) data of the logical channel becomes unavailable, the triggered DSR is cancelled. Exemplarily, the uplink data of the logical channel becomes unavailable, which may be: the uplink data of the logical channel is discarded.

[0198] Optionally, when there are no uplink authorized resources for uplink transmission, or when there are uplink authorized resources but the logical channel multiplexing rules are not met, resulting in the failure of the MAC CE transmission of the DSR, the DSR will trigger the transmission of the SR. If the terminal detects that a high-layer data packet is discarded, the triggered SR will be canceled. Optionally, the cancellation of the triggered SR may include: canceling the waiting SR of the DSR and stopping the prohibition timer of the SR (if the prohibition timer is running). Here, when the originally triggered DSR is canceled, the originally triggered DSR triggers an SR again, and the SR is canceled.

[0204] In some embodiments, the protocol stipulates that the terminal is enabled to cancel the triggered DSR and / or SR and / or RACH operations upon detecting that a higher layer data packet is discarded, only for a specific logical channel.

[0205] Optionally, if the network device enables the packet discard function of a data packet (such as a PDU or PDU set of PDCP) for a certain logical channel or logical channel group, the uplink logical channel associated with the PDCP entity can enable the terminal to cancel the triggered and / or SR and / or RACH operations when a high-level data packet discard is detected.

[0206] Alternatively, assume that dropping a packet renders the entire PDU set invalid.

[0207] Here are some examples:

[0208] Example 1:

[0209] Optionally, when a higher-layer data packet is discarded or a logical channel is detected whose uplink data changes from being present to being absent, the sending of the DSR is canceled.

[0212] Example 3:

[0213] Optionally, when a higher-layer data packet is discarded or a logical channel is detected whose uplink data is no longer available, the RACH process is canceled. Exemplarily, when a higher-layer data packet is discarded or a logical channel is detected whose uplink data is no longer available, the DSR's triggered or pending SR transmission is canceled; when the triggered or pending SR is canceled, the RACH process is canceled. Exemplarily, the MAC entity may cancel an ongoing RACH process.

[0214] Example 4:

[0215] Optionally, when a higher-layer packet is discarded or a logical channel is detected whose uplink data is no longer available, the RACH process is canceled. For example, when a higher-layer packet is discarded or a logical channel is detected whose uplink data is no longer available, the MAC entity may cancel the ongoing RACH process. The ongoing RACH process is caused by a pending SR triggered by a DSR.

[0216] Example 5:

[0217] Optionally, when a high-level data packet is discarded or a logical channel is detected whose uplink data goes from being present to being absent, and the DSR that triggered the SR is canceled, the DSR-triggered or pending SR is canceled; and the prohibition timer of the SR is stopped (if the prohibition timer is running).

[0218] Example 6:

[0219] Optionally, when a high-layer data packet is discarded or a logical channel is detected whose uplink data changes from being present to being absent, and the DSR associated with the SR that triggered the RACH process is canceled, the RACH process is canceled; wherein the RACH process is initiated by the SR triggered by the DSR.
