[0106] The terms and concepts involved in the embodiments of this disclosure are described below.

[0107] I. Uplink authorization (UL grant).

[0108] A UL grant is an uplink resource authorization sent by a network device to a terminal, indicating when, where, and how the terminal will send uplink data. A UL grant typically contains the following key information: (1) time-frequency resource allocation information, used to indicate the time-domain and frequency-domain resources for uplink transmission to the terminal; (2) modulation and coding scheme information, used to indicate the modulation scheme and coding rate used to the terminal; (3) transport block size information, used to indicate the amount of data that can be sent to the terminal; and (4) power control information, used to modulate the transmit power of the terminal.

[0109] In some embodiments, a UL grant can also be described as an uplink license, uplink authorized resource, etc.

[0110] In some embodiments, a UL grant may be obtained in the following ways:

[0111] (1) Dynamic scheduling: Dynamic allocation through downlink control information (DCI);

[0112] (2) Semi-persistent scheduling (SPS): SPS configured through RRC periodically reuses resources after initial allocation.

[0113] (3) Random access response (RAR): During the random access process, the network device provides a UL grant through RAR.

[0114] (4) Configured (CG) uplink authorization: Uplink authorization configured via RRC.

[0115] In some embodiments, when a terminal sends a data packet to a receiving end using a UL grant, the data packet originates from the application layer of the sending end, passes through the radio resource control (RRC) layer, service data adaptation protocol (SDAP) layer, PDCP layer, radio link control (RLC) layer, media access control (MAC) layer, and physical (PHY) layer of the sending end, then passes through the transmission link to the PHY layer of the receiving end, and then through the MAC layer, RLC layer, PDCP layer, SDAP layer, and RRC layer of the receiving end, finally reaching the application layer of the receiving end.

[0116] In some embodiments, the sending end in the above data packet transmission process can be a terminal, and the receiving end can be a network device. In some embodiments, the sending end in the above data packet transmission process can be a network device, and the receiving end is a terminal. In some embodiments, the sending end in the above data packet transmission process can be terminal A, and the receiving end can be terminal B. In some embodiments, the sending end in the above data packet transmission process can be network device A, and the receiving end can be network device B.

[0117] In some embodiments, a packet can be understood as a data unit, which includes a protocol data unit (PDU) and a service data unit (SDU). In some embodiments, all data sent from or to an upper layer is called an SDU, and all data sent to or received from a lower layer is called a PDU. That is, the packet in this embodiment includes at least one of the following: an SDU, or a PDU associated with an SDU.

[0118] II. LCP process.

[0119] When a terminal receives a UL grant from a network device and obtains the Physical Uplink Shared Channel (PUSCH) transmission resource allocated to it as indicated by the grant, it determines which logical channels (LCHs) to transmit data on that resource through the LCP procedure. The LCP procedure mainly targets the behavior of the uplink terminal device.

[0120] Network devices are configured with the following parameters for each LCH to control the LCP process:

[0121] (1) Priority: The larger this parameter is, the lower the priority of LCH;

[0122] (2) Prioritized bit rate (PBR): The rate at which tokens are added to the token bucket. 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 PBR under resource constraints.

[0123] (3) Bucket size duration (BSD): BSD can be understood as the depth of the token bucket, which determines the upper limit of PBR accumulation. The maximum capacity of the token bucket is PBR×BSD.

[0124] In addition, the base station can configure the following mapping restriction parameters for the LCH to match and select the LCH that can transmit data each time a grant is received:

[0125] (1) allowedSCS-list: This indicates the subcarrier spacing (SCS) that the LCH can use for transmission resources. For example, if LCH1 is configured with this parameter as 15kHz, then the data of LCH1 can only be transmitted through carriers with a subcarrier spacing of 15kHz; if this parameter is not configured, the data of LCH1 can be transmitted through carriers with any SCS.

[0126] (2) maxPUSCH-Duration: This indicates the maximum PUSCH time domain length allowed for LCH transmission. For example, if LCH1 is configured with this parameter as 0.5ms, then LCH1 data can only be transmitted using PUSCH resources with a time domain length less than or equal to 0.5ms; if this parameter is not configured, LCH1 data can be transmitted using PUSCH resources of any length.

[0127] (3)configuredGrantType1Allowed: Indicates whether the LCH can use the configuration grant resource of Type1. For example, if LCH1 is configured with this parameter as true, then the data of LCH1 can be transmitted on the configuration grant resource of Type1.

[0128] (4) allowedServingCells: Indicates which cell transmission resources this LCH can use. For example, if LCH1 is configured with this parameter as ID1, then LCH1's data can only be transmitted using the resources of the cell with index ID1; if this parameter is not configured, then LCH11's data can be transmitted using the resources of any serving cell.

[0129] (5) allowedCG-List: Indicates which configuration licensed resources this LCH can use. For example, if LCH1 is configured with this parameter as ID1, then LCH1's data can only be transmitted on the configuration licensed resource with index ID1, and cannot be transmitted on other configuration licensed resources; if this parameter is not configured, then LCH1's data can be transmitted on any configuration licensed resource.

[0130] (6) allowedPHY-PriorityIndex: This can take the value p0 or p1, representing high priority and low priority respectively, indicating which priority of dynamically granted resources this LCH can use. For example, if LCH1 is configured with this parameter as p0, then LCH1's data can be transmitted using resources with a dynamic grant (DG) indication of PHY-priority and a value of p0, or it can be transmitted using resources without a DG indication of PHY-priority; if LCH1 is configured with this parameter as p1, then LCH1's data can only be transmitted using resources with a DG indication of PHY-priority and a value of p1; if LCH is not configured with this parameter, then LCH1's data can be transmitted using any DG indication resource.

[0131] (7)allowedHARQ-mode: indicates the uplink hybrid automatic repeat request (HARQ) mode that this LCH can use.

[0132] III. Multimedia Services.

[0133] Multimedia services include augmented reality (AR), virtual reality (VR), extended reality (XR), mixed reality (MR) cloud gaming, and more.

[0134] In some embodiments, when a terminal initiates a multimedia service request, the core network device establishes a corresponding PDU session. A PDU session can contain multiple quality of service (QoS) streams, and different QoS streams have different QoS requirements.

[0135] In some embodiments, multimedia services have extremely stringent requirements for end-to-end latency, such as packet delay budget (PDB), meaning that data packets must be transmitted within the delay budget. For example, during the encoding and transmission process of multimedia services, the granularity of data processing is no longer data packets, but rather a set of PDUs. The latency requirement for a PDU set is the PDU Set Delay Budget (PSDB), meaning that all data in the PDU set must be transmitted within the delay budget. For instance, in some cases, multiple QoS streams of a multimedia service need to arrive at the server simultaneously for them to be correctly decoded; a delay in any one QoS stream will cause the joint decoding of multiple QoS streams to fail.

[0136] In some embodiments, the QoS requirements of multimedia services are dynamically changing. For example, for head-mounted devices (such as virtual reality headsets, VR headsets, AR glasses, etc.), the field of view (FOV) changes abruptly as the user quickly turns or tilts their head. The system must transmit the new video data to the core network; otherwise, visual stuttering or degradation will occur. That is, newly entering video content within the FOV must be transmitted with priority, while video content within the existing FOV can be downgraded for transmission.

[0137] In some embodiments, in emergency avoidance scenarios, environmental awareness data packets should be transmitted before entertainment data packets; otherwise, it will pose a security risk.

[0138] For multimedia services, the service content is dynamically changing, but the current LCP configuration is static, which cannot respond to the dynamic adjustment requirements of service QoS. Moreover, the scheduling logic of the LCP process is rigid, lacks awareness of service content, and cannot proactively adapt to the dynamic needs of the service, thus affecting the user experience.

[0139] Therefore, the current LCP process does not meet the needs of multimedia services. Optimizing the LCP process for multimedia service data packets is an urgent problem to be solved.

[0140] This disclosure provides a communication method, communication device, communication system, storage medium, and program product. The access network device sends first information to the terminal to help the terminal determine changes in LCP configuration. The changes in LCP configuration are determined based on changes in services. In this way, the LCP configuration can be dynamically adjusted based on changes in services, realizing an LCP process that accurately matches the dynamic needs of services and significantly improving the user experience.

[0141] Figure 2A This is an interactive schematic diagram of the communication method provided according to embodiments of this disclosure. For example... Figure 2A As shown, this disclosure relates to a communication method. Executed by a communication system 100, the communication method includes steps S2101 to S2103.

[0142] In step S2101, the terminal sends the second information to the access network device.

[0143] In some embodiments, the second information is used to determine the LCP configuration or a change in the LCP configuration. In some embodiments, the second information is used to request the access network device to send the LCP configuration. In some embodiments, the second information is used to request the access network device to update the LCP configuration. In some embodiments, the second information is used to trigger the access network device to update the LCP configuration.

[0144] In some embodiments, the second information is sent by the terminal when it determines that a service has changed. In some embodiments, the second information is used to indicate a service change, which is used to determine an LCP configuration change. In some embodiments, the service change includes at least one of the following: a change in service content, a change in service priority, a change in service type, a change in service QoS requirements, or a change in coordination requirements between multiple services.

[0145] In some embodiments, changes in services may occur at the level of a single terminal or a single service, or in the case of multiple terminals operating collaboratively or multiple services sharing collaboratively, or in the case of switching operating modes. Switching operating modes includes: switching from a single-terminal operating mode to a multi-terminal collaborative operating mode, and switching from a multi-terminal collaborative operating mode back to a single-terminal operating mode.

[0146] In some embodiments, changes in service content can be triggered by user movement, user interaction events, or the fulfillment of preset conditions. In some embodiments, changes in service content include at least one of the following: changes in video content, audio content, text content, haptic content, changes in service interaction modes, and changes in service data characteristics. In some embodiments, interaction modes include gesture interaction, voice interaction, and device interaction. Device interaction includes keyboard interaction, mouse interaction, and gamepad interaction. In some embodiments, changes in service data characteristics include at least one of the following: changes in the amount of service data, changes in the transmission rate of service data, and changes in the latency sensitivity of service data.

[0147] In one example, in an XR scenario, the user moves or rotates the head-mounted display rapidly, causing the field of view (FOV) to change quickly, at which point the video content changes drastically.

[0148] In one example, in a VR meeting scenario, a user accesses a shared document, and the content of the document should be added to the FOV of all participants. At this point, the video content of all participants changes.

[0149] In one example, during an MR remote surgery training scenario, the tactile content changes as the user manipulates virtual surgical instruments to touch an organ model.

[0150] In one example, when a user switches the device interaction mode to voice interaction, it is necessary to transmit the voice stream in real time and display the corresponding text content, meaning that the audio content and text content change.

[0151] In one example, in an XR scenario, when a user enters a complex virtual environment (such as a dense cluster of buildings), the video stream bitrate suddenly increases from 20Mbps to 50Mbps, which is called a data burst.

[0152] In one example, switching from "preload XR content" to "real-time multiplayer XR battles" reduced latency requirements from hundreds of milliseconds to tens of milliseconds.

[0153] In some embodiments, changes in service priority include decreasing or increasing service priority. That is, the relative priority order of the same service changes.

[0154] In some embodiments, the type of service includes at least one of the following: real-time service, non-real-time service, high-volume service, low-volume service, two-way interactive service, one-way broadcast service, periodic service, event-triggered service, large-scale connection service, and high-mobility connection service.

[0155] In some embodiments, real-time services include video calls and voice calls. Non-real-time services include text chat and SMS. High-bandwidth services include video calls and cloud storage backup. Low-bandwidth services include SMS and location check-in. Two-way interactive services include cloud gaming and video calls, while one-way broadcast services include software update notifications and live TV. Periodic services include periodic sensor reporting and heartbeat packets. Event-triggered services include smoke sensor alarms and QR code payment.

[0156] In one example, a user switches from WeChat chat to WeChat video call, at which point the service type changes.

[0157] In some embodiments, changes in the QoS requirements of a service include at least one of the following: changes in latency requirements, changes in packet loss rate requirements, changes in throughput requirements, changes in bandwidth requirements, and changes in error rate requirements.

[0158] In some embodiments, changes in the collaboration requirements among multiple services include at least one of the following: changes in the relationships between multiple services, or changes in the resource sharing patterns among multiple services.

[0159] In some embodiments, the relationship between multiple services can also be described as a dependency relationship between multiple services. A dependency relationship can be understood as the processing of one service depending on the processing of another service. In some embodiments, changes in the relationship between multiple services include: an independent relationship becoming a dependency relationship, and a dependency relationship becoming an independent relationship.

[0160] In one example, VR video consists of three QoS streams: a video stream (image), an audio stream (audio), and a gesture stream (user head movements). In normal scenarios, these three QoS streams can be transmitted independently. However, in immersive interactive scenarios, all three QoS streams need to arrive at the terminal simultaneously to complete joint decoding; any delay in any QoS stream will cause stuttering. In other words, the relationship between the three QoS streams changes.

[0161] In one example, when a user watches 4K video (eMBB service), the video needs to be uploaded to the cloud simultaneously (cloud storage service). At this time, the upload service needs to wait for the data after the video is decoded, that is, the video playback and upload services change from an independent relationship to a dependent relationship.

[0162] In some embodiments, the second information indicates at least one of the following: the user's FOV changes, burst data arrives at the access layer, burst data arrives at the access layer and the importance of the burst data is greater than a first threshold, multiple data packet sets belonging to different services arrive at the access layer and there is a correlation between the multiple data packet sets, the priority of the QoS flow, the service scenario identifier, and the QoS parameters of the service.

[0163] In some embodiments, when the second information indicates a change in the user's FOV, the access network device can determine that the service content has changed and modify the LCP configuration based on the change in service content. In some embodiments, when burst data arrives at the access layer of a terminal or the terminal predicts that burst data will arrive at the access layer, the access network device can determine that the service type and / or the service's QoS requirements have changed and modify the LCP configuration accordingly. In some embodiments, when burst data arrives at the access layer and the importance of the burst data is greater than a first threshold, the access network device can determine that the service type and / or the service's QoS requirements have changed and modify the LCP configuration accordingly. In some embodiments, when the second information indicates that multiple sets of data packets belonging to different services arrive at the access layer and there is a correlation between the multiple sets of data packets, the access network device can determine that the coordination requirements between the multiple services have changed and modify the LCP configuration of the multiple services accordingly.

[0164] In some embodiments, the terminal predicts that burst data will arrive at the access layer based on at least one of the following: (1) the size of the buffer; (2) a first indication information carried in the header of the data packet; (3) a second indication information sent by the terminal's application layer; and (4) an artificial intelligence (AI) or machine learning (ML) model.

[0165] In some embodiments, if the amount of data in the buffer is greater than or equal to a first threshold, the terminal predicts that burst data will arrive at the access layer. In some embodiments, if the amount of data in the buffer is less than a second threshold, the terminal predicts that no burst data will arrive at the access layer. In some embodiments, if the amount of data in the data packet set to which the first indication information belongs is greater than or equal to the first threshold, the terminal predicts that burst data will arrive at the access layer. In some embodiments, if the amount of data in the data packet set to which the first indication information belongs is less than the second threshold, the terminal predicts that no burst data will arrive at the access layer. In some embodiments, if the second indication information indicates that burst data has arrived at the access layer, the terminal predicts that burst data has arrived at the access layer. In some embodiments, if the second indication information indicates that no burst data has arrived at the access layer, the terminal predicts that no burst data has arrived at the access layer. In some embodiments, the terminal can use the size of the data in the buffer at a historical time, the arrival time of the burst data at a historical time, and the amount of the burst data at a historical time as input data for the AI / ML model, and output the prediction result through the AI / ML model. The prediction result may include: whether burst data will arrive at the access layer in the future, the arrival time of the burst data, and the amount of the burst data. In some embodiments, the first threshold may be the same as or different from the second threshold.

[0166] In some embodiments, business scenario identifiers include, for example, FOV mutation identifiers, interaction mode switching identifiers, and autonomous driving emergency avoidance identifiers.

[0167] In some embodiments, the second information may also indicate at least one of the following: a change in the state of the terminal, or a change in the capabilities of the terminal. In some embodiments, a change in the state of the terminal includes at least one of the following: the terminal switches from a stationary state to a mobile state, the terminal switches from a mobile state to a stationary state, the terminal switches from a connected state to a disconnected state, or the terminal switches from a disconnected state to a connected state.

[0168] Understandably, changes in the terminal's state and capabilities can cause the original LCP configuration to become incompatible. Therefore, by reporting its own state and capability changes, the terminal facilitates the access network equipment in updating its LCP configuration.

[0169] In one example, the terminal's battery level changes (e.g., the remaining battery level is less than 10%). In this case, the UE can report the low battery condition or low power consumption requirement to the network, and the network device can adjust the LCP configuration based on the battery level.

[0170] In some embodiments, the terminal may send the second information to the access network device via at least one of RRC signaling, MAC CE signaling, non-access stratum (NAS) signaling, PDCP control PDU, and packet headers. In some embodiments, the terminal may carry the second information in the GPRS tunneling protocol for the user plane (GTP-U) packet header.

[0171] In some embodiments, step S2101 can also be performed by the core network device, i.e., the core network device sends the second information to the access network device. In some embodiments, the second information sent by the core network device to the access network device can be obtained from the terminal or other access network devices.

[0172] In some embodiments, step S2101 may also be performed by other access network devices. For example, the second access network device sends second information to the first access network device. In some embodiments, the second access network device is the access network device before cell reselection, and the first access network device is the access network device after cell reselection. In some embodiments, the second access network device is the access network device before cell handover, and the first access network device is the access network device after cell handover. In some embodiments, the second access network device is an anchor device (e.g., an anchor base station), and the first access network device is an access network device connected to the anchor device. In some embodiments, the second access network device is the primary base station, and the first access network device is the secondary base station.

[0173] In step S2102, the access network device sends the first information to the terminal.

[0174] In some embodiments, the access network device sends first information to the terminal based on second information. In some embodiments, the access network device sends first information to the terminal based on second information sent by the terminal. In some embodiments, the access network device sends first information to the terminal based on second information sent by the core network device. In some embodiments, the access network device sends first information to the terminal based on both second information sent by the terminal and second information sent by the core network device. In some embodiments, the second information is used to determine the first information. In some embodiments, the first information is used to determine a change in the LCP configuration. In some embodiments, the first information is used to update the LCP configuration.

[0175] In some embodiments, the first information is used to change the LCP configuration to relax LCP restrictions. In some embodiments, relaxing LCP restrictions includes at least one of the following: relaxing the scope of UL grant usage, relaxing TBS restrictions, relaxing logical channel multiplexing restrictions, and relaxing scheduling timing restrictions.

[0176] In some embodiments, the first information is used to change the LCP configuration to tighten LCP restrictions. In some embodiments, tightening LCP restrictions includes at least one of the following: tightening the UL grant usage scope, tightening TBS restrictions, tightening logical channel multiplexing restrictions, and tightening scheduling timing restrictions.

[0177] In some embodiments, the LCP configuration includes at least one of the following: the logical channel group (LCG) to which the LCH belongs, the priority of the LCH, the PBR of the LCH, the BSD of the LCH, the maximum bit rate (MBR) of the LCH, the resource types that the LCH is allowed to use, the maximum transport block size (TBS) of the LCH, the usage status of the LCH, the scheduling timing of the LCH, and the multiplexing rules of the LCH.

[0178] In some embodiments, the resource types allowed for use by the LCH include at least one of the following: dynamic granting, SPS granting, and CG granting. In some embodiments, dynamic granting includes dedicated dynamic granting and shared dynamic granting. Dedicated dynamic granting refers to resources specifically configured for the LCH by the network, while shared dynamic granting refers to resources shared by multiple LCHs. In some embodiments, dynamic granting can be described as dynamic scheduling granting, dynamic uplink granting (UL grant), dynamic licensing, dynamic uplink licensing, etc. In some embodiments, SPS granting can be described as SPS uplink granting. In some embodiments, CG granting can be described as CG uplink granting.

[0179] In some embodiments, the usage status of LCH includes: available status and disabled status.

[0180] In some embodiments, the first information indicates at least one of the following: whether the LCP configuration has been changed, the conditions for changing the LCP configuration, the number of LCP configurations corresponding to the LCH has changed, the LCH corresponding to the changed LCP configuration, the changed LCP configuration, the LCP configuration changing from an active state to a deactivated state, the LCP configuration changing from a deactivated state to an active state, and the duration of the LCP change.

[0181] In some embodiments, the first information indicates a change in LCP configuration, in which case all LCP configurations are changed. In some embodiments, the first information indicates no change in LCP configuration, in which case all LCP configurations remain unchanged. In some embodiments, the first information indicates a change in the LCP configuration of a specific LCH, in which case only the LCP configuration of the specific LCH indicated by the first information is changed. In some embodiments, the first information indicates no change in the LCP configuration of a specific LCH, in which case only the LCP configuration of the specific LCH indicated by the first information remains unchanged.

[0182] In one example, the first information includes change indication information, which indicates whether the LCP configuration has been changed. When the change indication information is carried in the header of a data packet (e.g., the GTP-U header), the change indication information is used to indicate whether the LCP configuration of the logical channel in which the data packet carrying the change indication information resides has been changed.

[0183] In some embodiments, the conditions for changing the LCP configuration include at least one of the following: the time of the LCP configuration change, the event that triggers the LCP configuration change, and the location of the terminal that triggers the LCP change. That is, the LCP configuration change is not executed immediately after the access network device indicates it, but only when the change conditions are met. In one example, if the LCP configuration change time is the time the terminal receives the first information, then the LCP configuration change takes effect immediately after the access network device indicates it.

[0184] In some embodiments, the timing of LCP configuration changes can be understood as the time when the LCP configuration is triggered to change, or the time period during which the LCP configuration change is triggered. That is, the time when the change is triggered.

[0185] In some embodiments, events that trigger LCP configuration changes include: changes in network status, changes in service requirements, changes in terminal capabilities, cell handover, and cell reselection. In one example, changes in network status can be changes in network resources, changes in network load, or changes in network data volume.

[0186] In some embodiments, the location of the terminal that triggers the LCP change includes roaming area, non-roaming area, disaster area, non-disaster area, primary cell, and secondary cell.

[0187] In some embodiments, the first information indicates a change in the number of LCP configurations corresponding to an LCH. For example, the first information indicates that an LCH has changed from corresponding to one LCP configuration to corresponding to multiple LCP configurations. For example, the first information indicates that an LCG has changed from corresponding to one LCP configuration to corresponding to multiple LCP configurations.

[0188] In some embodiments, multiple LCP configurations are used for at least one of the following: LCP processing of different packets in the same LCH; LCP processing of the same LCH at different times; LCP processing of the same LCH under different conditions.

[0189] In this context, different LCP configurations within multiple LCP configurations can correspond to different data packets within the same LCH, and different data packets are processed using different LCP configurations. These different data packets can be packets with different identifiers or packets of different types. Data packet types are categorized according to one of the following: priority, importance, data frame, data slice, data tile, metadata, audio data, text data, or image data.

[0190] In this context, different LCP configurations within multiple LCP configurations can correspond to different data packets within the same LCH. When processing different data packets, different LCP configurations take effect. In one example, the LCP configurations for LCH1 include LCP configuration 1 and LCP configuration 2. LCP configuration 1 corresponds to high-priority data packets, and LCP configuration 2 corresponds to low-priority data packets. When processing high-priority data packets in LCH1, LCP processing is performed based on LCP configuration 1, and when processing low-priority data packets in LCH1, processing is performed based on LCP configuration 2.

[0191] Among these, different LCP configurations can correspond to different times, and different LCP configurations take effect at different times.

[0192] Among these, different LCP configurations can correspond to different situations / conditions, and different LCP configurations will take effect under different situations / conditions.

[0193] In some embodiments, the first information indicating the LCH corresponding to the changed LCP configuration can be understood as the first information indicating which LCHs' LCP configurations need to be changed. In some embodiments, the first information indicating the LCG corresponding to the changed LCP configuration can be understood as the first information indicating which LCGs' LCP configurations need to be changed.

[0194] In some embodiments, the change from an active to a deactivated state of the LCP configuration can be understood as the LCP configuration changing from an available state to an unavailable state, or from an enabled state to a disabled state. The change from a deactivated to an active state of the LCP configuration is similar and will not be described further.

[0195] In some embodiments, the duration of an LCP configuration change can be understood as the terminal using the changed LCP configuration throughout the duration, meaning the changed LCP configuration is valid for the duration. After the duration, the terminal can continue to use the previous LCP configuration for LCP processing.

[0196] In one example, the duration of the LCP configuration change is one week, so the terminal uses the changed LCP configuration for LCP processing for one week.

[0197] In one example, when the FOV changes, the first message indicates that the priority of the LCH containing the video stream in the new FOV should be increased. In another example, the first message indicates that the PBR of the LCH containing the video stream in the new FOV should be increased. In yet another example, the first message indicates that the BSD of the LCH containing the video stream in the new FOV should be increased.

[0198] In one example, in an autonomous driving emergency avoidance scenario, the first information indicates that the priority of the LCH containing the environmental perception data should be increased. In another example, the first information indicates that the PBR of the LCH containing the environmental perception data should be increased. In yet another example, the first information indicates that the BSD of the LCH containing the video stream in the new FOV should be increased.

[0199] In one example, if the PBR included in the modified LCP configuration is infinite, then the LCH corresponding to the modified LCP configuration is not limited by the PBR.

[0200] In one example, the first information indicates that the LCP configuration changes from an active state to a deactivated state, the LCP configuration including the PBR, and the LCH corresponding to the LCP configuration is not limited by the PBR.

[0201] In one example, the first message indicates that a particular LCH is not subject to PBR restrictions.

[0202] In one example, the LCH corresponding to the modified LCP configuration is allowed to use any uplink grant resources; or, the LCH corresponding to the modified LCP configuration is allowed to use uplink grant resources of a non-serving cell.

[0203] In one example, the LCP configuration includes the resource types that the LCH is allowed to use, including: configuration authorized resources; the first information indicates that the LCP configuration changes from a deactivated state to an activated state, and the LCH corresponding to the LCP configuration that changes from a deactivated state to an activated state is allowed to use configuration authorized resources.

[0204] In one example, when a burst of data arrives at the access layer, the terminal directly uses CG authorization to send data according to the instructions of the first information, without waiting for dynamic network authorization.

[0205] In one example, when burst data arrives at the access layer, the first information indicates that the TBS of the LCH corresponding to the burst data should be increased, so that more data is transmitted at once and the number of transmissions is reduced.

[0206] In one example, the first information indicates that the first logical channel is allowed to multiplex packets with the second logical channel in the same MAC PDU. For example, the first logical channel is a high-priority logical channel, and the second logical channel is a low-priority logical channel.

[0207] In one example, the first information indicates that a particular logical channel is allowed to be scheduled in all available subframes, so that the UE can send data at any time, suitable for emergency services.

[0208] In step S2103, the terminal determines the LCP configuration and performs LCP processing according to the determined LCP configuration.

[0209] In some embodiments, the terminal may determine whether to change the LCP configuration based on the first information and its own implementation. In some embodiments, the terminal may determine whether to change the LCP configuration based on the first information and its own capabilities. In some embodiments, the terminal may determine whether to change the LCP configuration based on the first information and its own resource status. In some embodiments, the terminal may determine whether to change the LCP configuration based on the first information and its own load status. In some embodiments, the terminal may determine whether to change the LCP configuration based on the first information and its current operating status.

[0210] In some embodiments, when it is determined that the LCP configuration needs to be changed, the terminal may change the LCP configuration according to the instructions of the first information. In some embodiments, when it is determined that the LCP configuration needs to be changed, the terminal may adjust the changed LCP configuration indicated by the first information and change the LCP configuration according to the adjusted LCP configuration.

[0211] In some embodiments, if it is determined that the LCP configuration will not be changed, the terminal can continue to use the current LCP configuration, or in other words, continue to use the original LCP configuration. In this case, not changing the LCP configuration can also be understood as the LCP configuration change failing.

[0212] In some embodiments, if it is determined that the LCP configuration change has failed, the terminal can continue to use the current LCP configuration, or in other words, continue to use the original LCP configuration.

[0213] In some embodiments, the terminal performs LCP processing according to the modified LCP configuration. The terminal performs LCP processing on data packets based on the number of tokens in the token bucket. In some embodiments, the number of tokens in the token bucket is indicated by a variable Bj, which is updated by PBR and a time parameter T. The time parameter indicates the time elapsed since the last update of variable Bj. In one example, Bj = Bj + PBR × T.

[0214] In some embodiments, the terminal allocates uplink transmission resources to logical channels where B1j > 0 according to logical channel priority from high to low. In some embodiments, if the number of tokens in the token bucket does not support the transmission of data packets, the terminal sends data packets, and the value of variable Bj is negative. In some embodiments, if the number of tokens in the token bucket does not support the transmission of data packets, the terminal does not send data packets, and the variable Bj is not allowed to be negative.

[0227] In some embodiments, when the LCP configuration is changed, the access network device can either reprocess already processed data packets using the changed LCP configuration or ignore the changed LCP configuration and not reprocess the data packets.

The communication method involved in the embodiments of the present disclosure can be applied to network devices and terminals in the communication system 100. Figure 3 As shown, the communication method of this embodiment includes steps S3101 to S3102.

[0245] In step S3101, the network device sends the first information to the terminal.

[0246] In some embodiments, the first information is used by the terminal to determine changes in the LCP configuration during the logical channel priority (LCP) process, and the changes in the LCP configuration are determined based on changes in services.

[0247] Optional implementations of step S3101 can also be found in [reference 1]. Figure 2A Optional implementation methods of step S2102 Figure 2A Other related parts in the embodiments involved will not be described in detail here.

[0250] In the following, the technical solutions of the embodiments of this disclosure will be described by way of specific implementation.

[0251] In some embodiments, the network sends an instruction to the UE, instructing it to change the LCP parameters during the resource allocation process. The LCP process is the process by which the terminal allocates resources to the logical channel according to the uplink authorization after receiving the authorization.

[0252] In some embodiments, a network device (NW) can update logical channel priorities for a logical channel.

[0253] In some embodiments, a network device can indicate a logical channel whose PBR has changed.

[0254] In some embodiments, a network device may indicate a logical channel that is not restricted by the PBR, or the PBR is infinite.

[0255] In some embodiments, an NW can indicate a logical channel whose LCP restriction has been relaxed. For example, data in this LCH will be transmitted in any uplink grant, i.e., no longer subject to the restrictions imposed during LCP enforcement.

[0256] In some embodiments, the NW can indicate a logical channel for which it will activate a configured uplink grant for data transmission. Thus, for the terminal, data on a given logical channel can be directly transmitted uplink without waiting for downlink authorization.

[0257] In some embodiments, the target adjustment parameter value may be sent to the terminal in advance. In some embodiments, the NW may indicate a logical channel that its updated PBR uses.

[0258] In some embodiments, the base station instructs the terminal to make dynamic changes, which can be done via MAC CE, where the change instruction can be carried.

[0259] In some embodiments, the MAC CE may also indicate the target LCH or LCH list for the change.

[0260] In some embodiments, the MAC CE may also indicate the target scheduling parameters for the change, if the terminal has not been notified in advance.

[0261] In some embodiments, the gNB identifies that dynamic adaptation is needed from the UE's assistance information.

[0262] In some embodiments, when the FoV angle of the UE changes, the UE will indicate this to the gNB, and the gNB will then dynamically change the LCP parameters of the logical channel where the video stream is located.

[0263] In some embodiments, the gNB identifies that dynamic adaptation is needed from the core network's assistance information.

[0264] In some embodiments, if a large number of data of a specific PSI level arrive for a particular QoS flow, the UE notifies the base station, and the base station dynamically changes the LCP parameter of the logical channel in which the flow is located.

[0265] In some embodiments, if the CN detects that the QoS flow priority level has increased, it will notify the base station, and the base station will dynamically change the LCP parameters of the logical channel in which the flow is located.

[0266] In some embodiments, the core network can express the importance of urgent data by carrying data with a special PSI level.

[0267] In this way, the base station can obtain the QoS requirements based on content changes based on the auxiliary information of the terminal or the core network, and can adjust the scheduling method of the logical channel more flexibly.

[0268] In some embodiments, the core network informs the base station of the characteristics of QoS flows, such as which QoS flows are latency-sensitive and which QoS flows are motion-sensitive.

[0269] In some embodiments, if the base station detects that the terminal has reported a change in FOV angle, the base station dynamically changes the LCP parameters of the logical channel where the latency-sensitive QoS flow is located.

[0270] In the following method, some trigger conditions can be configured for the terminal, so that the terminal can change parameters such as LCP when the conditions are met.

[0271] In some embodiments, the UE can update logical channel priorities, PBR, etc. based on conditions fulfilling the detection of high PSI packets.

[0272] In some embodiments, if the terminal detects that the FOV angle change is higher than a threshold, it notifies the base station, and the base station selects the LCP parameter of the logical channel in which the flow is located for dynamic change or the terminal makes the change itself.

[0273] In some embodiments, if the terminal detects the arrival of data carrying a special PSI level, such as data with a special PSI level to express the importance of urgent data.

[0274] In some embodiments, the network device pre-configures updated parameters for the UE, such as a list of LCHs that will be prioritized. When the condition is met, the UE will prioritize the LCHs to higher priorities.

[0275] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0276] In some embodiments, one or more of the embodiments described above may be related to... Figure 2A , Figure 2B The embodiments are used in combination with each other.

[0277] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0278] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0279] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be hardware circuits designed for artificial intelligence, which can be understood as ASICs, such as Neural Network Processing Units (NPUs), Tensor Processing Units (TPUs), and Deep Learning Processing Units (DPUs).
