In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0101] In some embodiments, the network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0102] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0104] The embodiments of the present disclosure can be applied to information processing systems, 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 802.20, 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).

[0105] In XR services, data usually consists of multiple Quality of Service (QoS) flows, and its business volume is very large. XR business flows need to meet certain latency 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 network scheduling is dynamic, so 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 as soon as possible. However, according to the existing mechanism, 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.

[0106] In some embodiments, a Delay Status Report (DSR) is introduced. The basic idea is as follows: the terminal can report the DSR, which carries delay information. For example, the uplink data cannot be scheduled for a long time, resulting in the remaining time of its data packet being less than a certain threshold.

[0107] The remaining time of the data packet is the time until the packet is discarded, that is, the remaining time is determined according to a discard timer of the Packet Data Convergence Protocol (PDCP).

[0108] However, the mechanism for DSR reporting is still unclear.

[0109] The information processing method and device provided by the present disclosure are described in detail below with reference to the accompanying drawings.

[0110] FIG2A is an interactive diagram of an information processing method according to an embodiment of the present disclosure. As shown in FIG2A , the present disclosure embodiment relates to an information processing method, which includes:

[0111] Step S2101: Terminal 101 determines whether first data exists.

[0112] In some embodiments, the terminal 101 determines that first data exists in a logical channel (Logical Channel, LCH) or a logical channel group (Logical Channel Group, LCG).

[0143] FIG2B is an interactive diagram of an information processing method according to an embodiment of the present disclosure. As shown in FIG2B , the embodiment of the present disclosure relates to an information processing method, which includes:

[0144] Step S2201: Terminal 101 determines whether first data exists.

[0145] In some embodiments, the terminal 101 determines that there is first data in the logical channel LCH or the logical channel group LCG.

[0146] In some embodiments, the remaining time corresponding to the first data is less than a first threshold.

[0147] In some embodiments, the first data includes at least one data packet or a set of data packets.

[0148] Optionally, the data packet may be a protocol data unit (PDU), and the data packet set may be a PDU set.

[0149] In some embodiments, the remaining time corresponding to the first data refers to the time until at least one data packet or a set of data packets included in the first data is discarded.

[0150] In some embodiments, the remaining time corresponding to the first data can be determined according to a discard timer of PDCP.

[0151] In some embodiments, the first threshold may be pre-defined by a protocol, or configured by the network through signaling, or pre-agreed between the network and the terminal, which is not limited in this embodiment.

[0152] In some embodiments, the name of the first threshold is not limited, and it can be, for example, "remaining time threshold", "remaining time threshold (remainingTimeThreshold)", etc.

[0153] In some embodiments, the name of the first data is not limited, and may be, for example, "first characteristic data", "data to be discarded", "urgent data", etc.

[0154] In some embodiments, the terminal 101 determines that the first data exists, which can trigger a delay status report DSR.

[0155] In some embodiments, the DSR carries the size of the first data.

[0156] In step S2202, the terminal 101 sends a DSR to the network device 102 via a DSR MAC CE.

[0157] In some embodiments, network device 102 receives the DSR described above.

[0158] In some embodiments, the terminal 101 sends the above-mentioned DSR via a DSR MAC CE.

[0159] In some embodiments, the DSR includes the size of the first data.

[0160] In some embodiments, the terminal 101 determines that there are uplink grant (UL grant(s)) resources for transmitting the above-mentioned DSR MAC CE, and the terminal 101 sends the above-mentioned DSR MAC CE on the above-mentioned uplink grant resources.

[0161] In some embodiments, the MAC PDU may contain both the BSR MAC CE and the DSR MAC CE.

[0162] In some embodiments, there is a simultaneous triggering of BSR and DSR.

[0163] In some embodiments, the data size of the first data triggering the DSR may be smaller than the data size of the data triggering the BSR.

[0164] In some embodiments, the remaining time corresponding to the first data triggering the DSR may be smaller than the remaining time corresponding to the data triggering the BSR.

[0165] Step S2203 , the terminal 101 sends a scheduling request SR to the network device 102 .

[0166] In some embodiments, the terminal 101 determines that there are no uplink granted resources for transmitting the above-mentioned DSR MAC CE, and the terminal 101 can trigger the sending of a scheduling request (SR) to the network device 102.

[0167] In some embodiments, the terminal 101 determines that although there are uplink authorized resources, the above-mentioned DSR MAC CE fails to be sent because the logical channel multiplexing rules are not met. The terminal 101 can trigger the sending of a scheduling request SR to the network device 102.

[0168] In some embodiments, the scheduling request SR is used to request the network device 102 to configure resources for the DSR MAC CE (ie, request resources that can be used to transmit the DSR MAC CE).

[0169] In some embodiments, the terminal 101 may send a scheduling request SR to the network device 102 based on the first configuration information.

[0170] In some embodiments, the first configuration information may be sent by the network device 102 to the terminal 101 .

[0171] In some embodiments, the first configuration information is the SR resource configuration corresponding to the logical channel configuration that triggers the BSR, that is, the SR configuration corresponding to the existing BSR is reused.

[0172] In some embodiments, the first configuration information is an SR configuration specifically used to send the DSR MAC CE.

[0173] In some embodiments, the first configuration information may include one or more SR configurations on a bandwidth part (Bandwidth Part, BWP).

[0174] In some embodiments, the first configuration information includes multiple SR configurations on a BWP. The first configuration information may also include associations between the LCG or LCH that triggers the DSR and the multiple SR configurations. For example, when multiple LCHs trigger DSR simultaneously, the SR configuration corresponding to the LCH may be selected. For example, the SR configuration corresponding to the LCH with the smaller logical channel priority value may be selected.

[0175] In some embodiments, the first configuration information may be included in Radio Resources Control (RRC) signaling.

[0176] In some embodiments, the name of the above-mentioned first configuration information is not limited, and it can be, for example, "Logical Channel Configuration (LogicalChannelConfig)", "Scheduling Request Configuration", "Logical Channel Scheduling Request Configuration", etc.

[0177] Step S2204: Terminal 101 triggers a random access RACH process.

[0178] In some embodiments, a random access channel (RACH) process is triggered because no valid physical uplink control channel (PUCCH) resources exist when the SR is sent.

[0179] Step S2205: Terminal 101 cancels the triggered RACH process.

[0180] In some embodiments, the terminal 101 determines that there are uplink authorized resources for transmitting the above-mentioned DSR MAC CE, and cancels the above-mentioned RACH process triggered by the above-mentioned SR.

[0181] In some embodiments, the terminal 101 determines that there are uplink authorized resources for transmitting the first data, and cancels the RACH process triggered by the SR.

[0182] In some embodiments, the terminal 101 determines that there are uplink authorized resources for transmitting the data to be transmitted in the above-mentioned LCH or LCG, and cancels the above-mentioned RACH process triggered by the above-mentioned SR.

[0183] In step S2206, the terminal 101 cancels sending the above SR.

[0184] In some embodiments, the terminal 101 determines that there are uplink authorized resources for transmitting the above-mentioned DSR MAC CE, and cancels sending the above-mentioned SR.

[0185] In some embodiments, the terminal 101 determines that there are uplink authorized resources for transmitting the first data, and cancels sending the SR.

[0186] In some embodiments, the terminal 101 determines that there are uplink authorized resources for transmitting the data to be transmitted in the above-mentioned LCH or LCG, and cancels sending the above-mentioned SR.

[0187] In step S2207, the terminal 101 cancels sending the above-mentioned DSR.

[0188] In some embodiments, the terminal 101 determines that there are uplink authorized resources for transmitting the above-mentioned first data, and cancels sending the above-mentioned DSR.

[0189] For example, if terminal 101 reports 1000 bits of data to be sent in a BSR and also reports 100 bits of data to be sent in a DSR, i.e., the first data has a data size of 100 bits, then if network device 102 is configured with uplink granted resources capable of scheduling 100 bits of data, the DSR is canceled. Alternatively, the BSR is not canceled.

[0190] In some embodiments, the terminal 101 determines that there are uplink authorized resources for transmitting the data to be transmitted in the above-mentioned LCH or LCG, and cancels sending the above-mentioned DSR.

[0191] As an example, if the network device 102 is configured with uplink granted resources that can accommodate all pending data in the LCH or LCG, the DSR may be canceled. Alternatively, if a related timer, such as a retransmission timer, a periodic transmission timer, or a prohibition timer, is started during the DSR transmission process, the timer is stopped.

[0192] In some embodiments, the terminal 101 determines that there are uplink authorized resources for transmitting the above-mentioned DSR MAC CE, and cancels sending the above-mentioned DSR.

[0193] In some embodiments, when the network device 102 indicates to the terminal 101 that the data to be transmitted can be scheduled or the terminal 101 detects that the uplink grant is available, the triggered DSR will be canceled.

[0194] In some embodiments, the cancellation of the DSR will result in the cancellation of the pending SR and RACH procedures.

[0195] In some embodiments, when the DSR that triggered the SR is canceled, the pending SR triggered by the DSR is canceled.

[0196] In some embodiments, the prohibit timer (ProhibitTimer) corresponding to the SR is running, and the prohibit timer is stopped.

[0197] In some embodiments, the DSR corresponding to the SR that triggered the RACH process has been canceled, and the MAC entity may stop the ongoing random access process due to the stopping of the pending SR triggered by the DSR.
