Description

Technical Field

[0002] In New Radio (NR) systems, uplink data transmission is subject to the constraints of all preconfigured Logical Channel Priority (LCP) parameters.

[0046] To facilitate a better understanding of the embodiments of the present application, extended reality (eXtended Reality, XR) is described.

[0047] XR services include augmented reality (AR), virtual reality (VR), and mixed reality (MR). Currently, popular XR services use H.264 encoding technology to achieve image data compression, saving traffic and ensuring image quality. Existing H.264 technology encodes image data into the following three types of image frames:

[0048] I-frame (Intra-coded picture) is a complete image frame that can be generated and presented independently of other frames;

[0049] P-frames (Predicted pictures) contain only image changes relative to the previous frame. The receiver needs to combine the previous frames to generate the current frame and display it on the receiving terminal.

[0050] A B-frame (Bidirectional Predicted Picture) indicates how the current frame compares to the previous and next frames. The receiver generates the current frame by combining the previous and next frames.

[0051] The above-mentioned front frames and back frames are sorted according to the frame presentation time or the image acquisition time of the source end. The actual sending and receiving time may be adjusted according to the image decoding time of the receiver. For example, the sender can send according to the order of the receiver's image frame decoding time.

[0052] Different frame types correspond to different frame encoding methods, resulting in different levels of image compression. I-frames have a low degree of compression (i.e., the largest frame data volume), P-frames have a moderate degree of compression (i.e., the moderate frame data volume), and B-frames have a high degree of compression (i.e., the smallest frame data volume).

[0053] There are two ways to transmit XR images: a frame slice combination-based transmission method and a frame set (group of picture, GoP)-based transmission method.

[0054] Slice-based transmission: This method slices a data frame into multiple data blocks, then disperses and combines the slices of multiple image frames into multiple data blocks for transmission, achieving smooth traffic flow for XR service data. This method significantly reduces traffic fluctuations caused by differences in I / P / B frame data volume, but it significantly increases image frame transmission latency due to cross-transmission between image frames.

[0055] Frame collection-based transmission method: Figure 2As shown, based on the periodic nature of video streams, video frames are divided into video frame sets according to the I-frame cycle. An I-frame and all subsequent P-frames and B-frames up to the next I-frame constitute a frame set. Image frames are transmitted and played back at the receiver based on a frame cycle. The time interval between the arrival times of adjacent image frames is a frame cycle. The frame set-based transmission method avoids mixed transmission of image frames, ensuring timely transmission of generated image frames. However, due to the varying degrees of compression between I, P, and B frames, the frame data rate fluctuates.

[0056] To facilitate a better understanding of the embodiments of the present application, a protocol data unit (PDU) set is described.

[0057] At this stage, XR's business data can be modeled as a PDU set. A PDU set includes a group of PDUs so that the quality of service (QoS) of the data can be managed according to the PDU set when it is transmitted in a wireless network. According to the different video data transmission methods mentioned above, a PDU set can correspond to an image frame, for example, a complete P frame or B frame, or an XR business data slice; another image frame can contain several PDU sets. For example, when the image frame is transmitted according to the left and right eye lines of sight, the left eye image data of an image frame corresponds to a PDU set, and the right eye image data corresponds to another PDU set; in addition, when the image is transmitted in the direction of the visual axis and the direction of the non-visual axis, the image data in the direction of the visual axis corresponds to one PDU set, and the image data in the direction of the non-visual axis corresponds to another PDU set. The above is only an example to illustrate the modeling of the PDU set. Other possible forms of PDU set modeling do not constitute a limitation on the implementation of this application.

[0058] To facilitate a better understanding of the embodiments of the present application, the transmission of XR services in the NR network is described.

[0059] When an uplink XR data packet from the UE arrives at the Packet Data Convergence Protocol (PDCP) layer buffer from the application layer, a PDCP discard timer is started based on the initial value preconfigured by the base station. During the PDCP discard timer, the base station can schedule the UE to transmit the data packet to the base station. If the corresponding PDCP discard timer expires without the data being successfully transmitted, the data packet is discarded.

[0060] To facilitate a better understanding of the embodiments of the present application, a data transmission delay budget (eg, packet delay budget (PDB)) is described.

[0061] Different services have different Quality of Service (QoS) management requirements. In the 3rd Generation Partnership Project (3GPP) network, QoS parameters include service data rate requirements, service data transmission delay requirements, and service data transmission reliability requirements (such as packet loss rate). The network can set different QoS parameters based on the user experience objectives of different services.

[0062] Latency-sensitive services generally have stringent end-to-end latency requirements. Based on these requirements, the latency budget for each segment of the data transmission path is determined. When latency-sensitive service data is transmitted over the 3GPP air interface, the network determines the corresponding air interface latency budget and schedules resources to ensure data transmission within the given latency budget.

[0063] According to the current protocol, the PDB or PDU Set Delay Budget (PSDB) window for a data packet can be understood as the operating time window of the corresponding PDCP discard timer, that is, the time window between the start of the PDCP discard timer and its expiration. If the corresponding data packet is not successfully transmitted when the PDCP discard timer expires, the PDCP entity will discard the untransmitted PDCP PDU or the corresponding Radio Link Control (RLC) PDU.

[0064] When transmitting XR image data, the network can configure data transmission based on the PDU set. At this time, the network can configure the air interface transmission delay budget (i.e., PSDB) of the PDU set. The data packets contained in a PDU set correspond to the transmission window determined by the PSDB. Based on the current conclusions, the network can configure the corresponding PDCP discardTimer of the UE based on the PSDB to determine the transmission window of the PDU set or the data packets belonging to the PDU set.

[0065] To facilitate a better understanding of the embodiments of the present application, the wireless resource allocation for uplink data is explained.

[0066] For a logical channel (LCH), the base station can configure one or more of the following logical channel priority (LCP) parameters for it through the Radio Resource Control (RRC) protocol. When the UE generates a Media Access Control (MAC) PDU for an uplink transmission grant, it determines whether the LCH data can be placed in the MAC PDU and how much LCH data can be placed in the MAC PDU for transmission based on these pre-configured LCP parameters. The following are some LCP parameters in NR MAC:

[0067] Priority: The resource allocation priority of the logical channel. A larger value indicates a lower priority.

[0068] Prioritized Bit Rate: The bit rate of priority transmission of the logical channel;

[0069] Token bucket window length (bucketSizeDuration): used to indicate the window length of the amount of data that can be transmitted according to the priority transmission bit rate.

[0070] In addition, the base station can also configure one or more of the following LCP parameters for the LCH through the RRC protocol:

[0071] Allowed subcarrier spacing list (allowedSCS-List): indicates one or more subcarrier spacings that can be used for data transmission of an LCH;

[0072] Maximum PUSCH duration (maxPUSCH-Duration): indicates the maximum physical uplink shared channel (PUSCH) duration that can be used for data transmission on one LCH;

[0073] ConfiguredGrantType1Allowed: used to indicate that a Type 1 pre-configured grant can be used to transmit data of an LCH;

[0074] Allowed Serving Cells: indicates a list of cells that can be used to transmit data for an LCH.

[0075] Allowed preconfigured permission list (allowedCG-List): used to indicate the preconfigured transmission permission list that can be used to transmit data of one LCH;

[0076] AllowedPHY-PriorityIndex: used to set the corresponding priority of the dynamic permission that can be used to transmit data of an LCH;

[0077] Allowed HARQ mode (AllowedHARQ-mode): used to set the Hybrid Automatic Repeat reQuest (HARQ) mode that can be used to transmit data of one LCH.

[0078] To facilitate a better understanding of the embodiments of the present application, delay status reporting and uplink delay emergency data are explained.

[0079] Delay Status Report (DSR): Supports delay status reporting by Logical Channel Group (LCG). When the remaining delay budget of the data with the smallest remaining delay budget of an LCG is lower than a preconfigured threshold (such as the remaining time threshold (remainingTimeThreshold)), a delay status report for the LCG can be triggered. The data with the remaining delay budget of an LCG lower than the preconfigured threshold is called delay-critical data. In the delay status report of an LCG, the UE indicates the remaining delay budget of the data with the smallest remaining delay budget of an LCG and the amount of buffered data with the remaining delay budget lower than the preconfigured threshold.

[0080] In the PDCP protocol, a PDCP entity corresponding to an LCH determines the remaining delay budget of a data packet based on the remaining time of a discard timer of the data packet.

[0081] In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application are explained.

[0082] Because different uplink radio resources have different transmission delays and transmission reliability, the 3GPP protocol defines the LCP parameter to limit the uplink radio resources used by an LCH. This prevents an LCH's data from being mapped to inappropriate uplink radio resources, resulting in transmission delay and / or transmission reliability that does not meet QoS requirements.

[0083] However, when the remaining latency of uplink delay-critical data is very low, due to a shortage of matching radio resources, the base station fails to promptly send sufficient transmission grants to meet the uplink delay-critical data transmission requirements, while other radio resources (referred to as non-optimal radio resources) are available. If the existing pre-configured LCP parameters are not followed and the UE is not allowed to use these non-optimal radio resources to transmit uplink delay-critical data, non-optimal radio resources will be wasted, and the delay-critical data will not be transmitted and will be discarded.

[0084] Based on the above technical problems, the embodiments of the present application provide an uplink data transmission method, apparatus and equipment, which relaxes the LCP parameter restrictions on the terminal using uplink wireless resources to transmit the first uplink data (such as delayed emergency data), so that the terminal can use uplink wireless resources that were not originally used to transmit the first uplink data (called non-optimal wireless resources) to transmit the first uplink data, so that the first uplink data obtains a transmission opportunity, improves the probability of successful transmission of the first uplink data, and also improves the utilization rate of wireless resources, which can solve the problem of low probability of successful transmission of the first uplink data.

[0085] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0086] Figure 3 is a schematic flow chart of an uplink data transmission method 200 according to an embodiment of the present application, such as Figure 3 As shown, the uplink data transmission method 200 may include at least part of the following contents:

[0087] S210, the network side device sends the relevant configuration of LCP restriction relaxation to the terminal;

[0088] S220, the terminal receives the relevant configuration of the LCP restriction relaxation;

[0089] S230, the terminal determines at least one uplink transmission permission according to the relevant configuration of the LCP restriction relaxation;

[0090] S240, the terminal transmits first uplink data according to a target uplink transmission grant in the at least one uplink transmission grant;

[0091] S250: The network-side device receives the first uplink data.

[0092] It should be understood that Figure 3The steps or operations of the uplink data transmission method 200 are shown, but these steps or operations are only examples. The present application may also perform other operations or Figure 3 Variations of the various operations in .

[0093] In an embodiment of the present application, by relaxing the LCP parameter restrictions on the terminal's use of uplink wireless resources to transmit the first uplink data, the terminal can use uplink wireless resources that were not originally used to transmit the first uplink data (called non-optimal wireless resources) to transmit the first uplink data, so that the first uplink data obtains a transmission opportunity, increases the probability of successful transmission of the first uplink data, and reduces the transmission delay of the first uplink data.

[0094] In some embodiments, the first uplink data may be data with high delay requirements or delay-sensitive data, such as delay-critical data.

[0095] The embodiments of the present application can be applied to the data transmission of XR services, and can also be applied to the data transmission of ultra-reliable and low latency communication (URLLC) or the transmission of other urgent data with arbitrary delay.

[0096] In the embodiment of the present application, the uplink transmission grant in the at least one uplink transmission grant may also be referred to as a non-optimal uplink transmission grant. This type of uplink transmission grant does not allow the terminal to transmit the first uplink data before the LCP restriction is relaxed.

[0097] Exemplarily, the terminal transmits the first uplink data according to the target uplink transmission permission, which can be understood as the terminal transmitting the first uplink data on the radio resources corresponding to the target uplink transmission permission.

[0098] In some embodiments, after the first uplink data transmission is completed, the terminal may cancel the LCP restriction relaxation.

[0099] In some embodiments, the terminal may cancel the LCP restriction relaxation after a preset time period after the first uplink data transmission is completed.

[0100] In some embodiments, when the remaining delay budget of the first uplink data is lower than a preset threshold, the terminal may cancel the LCP restriction relaxation.

[0101] In some embodiments, the first uplink data satisfies at least one of the following:

[0102] In a case where the terminal does not have an uplink transmission grant that complies with the LCP configuration to transmit the second uplink data in an LCG, or in a case where the terminal does not have sufficient uplink transmission grants that comply with the LCP configuration to transmit all the second uplink data in an LCG, the first uplink data includes all the second uplink data remaining in the LCG, wherein the remaining delay budget of the second uplink data is lower than the first threshold;

[0103] In a case where the terminal does not have an uplink transmission grant that complies with the LCP configuration to transmit the second uplink data in an LCH, or in a case where the terminal does not have sufficient uplink transmission grants that comply with the LCP configuration to transmit all the second uplink data in an LCH, the first uplink data includes all the second uplink data remaining in the LCH, wherein the remaining delay budget of the second uplink data is lower than the first threshold;

[0104] The first uplink data includes data indicating that a remaining delay budget in an LCG is lower than a second threshold or data indicating that a remaining delay budget in an LCH is lower than a second threshold;

[0105] The first uplink data includes data whose remaining delay budget in an LCG is within a first remaining delay range or data whose remaining delay budget in an LCH is within the first remaining delay range;

[0106] When the terminal is configured to perform an operation based on a PDU set for an LCG or an LCH, and a remaining delay budget of at least one PDU of a PDU set of the LCG or the LCH is lower than a third threshold, the first uplink data includes all PDUs to be transmitted in the PDU set;

[0107] When the terminal is configured to perform a PDU set-based operation on an LCG or LCH, and the residual delay budget of at least one PDU of a PDU set of the LCG or LCH is within the second residual delay range, the first uplink data includes all PDUs to be transmitted in the PDU set.

[0108] It should be noted that the lower boundary of the first remaining delay range is intended to prevent situations where, due to excessive transmission delay using non-optimal radio resources, the first uplink data would exceed the remaining delay budget even if it was transmitted correctly the first time, resulting in the first uplink data being discarded even if it reached the application server or the peer end. Similarly, the lower boundary of the second remaining delay range is intended to prevent situations where, due to excessive transmission delay using non-optimal radio resources, the first uplink data would exceed the remaining delay budget even if it was transmitted correctly the first time, resulting in the first uplink data being discarded even if it reached the application server or the peer end.

[0109] Exemplarily, the first threshold may be a remaining time threshold (remainingTimeThreshold).

[0110] Exemplarily, the second uplink data may be time-delayed emergency data determined based on a remaining time threshold (remainingTimeThreshold) (ie, a threshold for triggering DSR).

[0111] In some embodiments, the second threshold is configured at an LCG or LCH granularity. For example, if the second threshold is configured at an LCG granularity, in this case, the first uplink data includes data indicating that the remaining delay budget in an LCG is lower than the second threshold. For another example, if the second threshold is configured at an LCH granularity, in this case, the first uplink data includes data indicating that the remaining delay budget in an LCH is lower than the second threshold.

[0112] In some embodiments, the configuration granularity of the first residual delay range is LCG or LCH. For example, if the configuration granularity of the first residual delay range is LCG, in this case, the first uplink data includes data in an LCG whose residual delay budget falls within the first residual delay range. For another example, if the configuration granularity of the first residual delay range is LCH, in this case, the first uplink data includes data in an LCH whose residual delay budget falls within the first residual delay range.

[0113] In some embodiments, the configuration granularity of the third threshold is LCG or LCH. For example, the configuration granularity of the third threshold is LCG. In this case, when the terminal is configured to perform an operation based on a PDU set on an LCG, and the remaining delay budget of at least one PDU of a PDU set of the LCG is lower than the third threshold, the first uplink data includes all PDUs to be transmitted in the PDU set. For another example, the configuration granularity of the third threshold is LCH. In this case, when the terminal is configured to perform an operation based on a PDU set on an LCH, and the remaining delay budget of at least one PDU of a PDU set of the LCH is lower than the third threshold, the first uplink data includes all PDUs to be transmitted in the PDU set.

[0114] In some embodiments, the configuration granularity of the second remaining delay range is LCG or LCH. For example, the configuration granularity of the second remaining delay range is LCG. In this case, when the terminal is configured to perform an operation based on a PDU set on an LCG, and the residual delay budget of at least one PDU of a PDU set of the LCG is within the second residual delay range, the first uplink data includes all PDUs to be transmitted of the PDU set. For another example, the configuration granularity of the second remaining delay range is LCH. In this case, when the terminal is configured to perform an operation based on a PDU set on an LCH, and the residual delay budget of at least one PDU of a PDU set of the LCH is within the second residual delay range, the first uplink data includes all PDUs to be transmitted of the PDU set.

[0115] In some embodiments, the second threshold and the first threshold are configured separately by the network side (such as a base station); or the first threshold is used as the second threshold.

[0116] In some embodiments, the second threshold is smaller than the first threshold. That is, the first uplink data determined based on the second threshold is more likely to fail in transmission than the time-delayed urgent data determined based on the first threshold, and is more urgently in need of relaxing the LCP restriction so as to temporarily use radio resources not originally used for transmission to transmit the first uplink data.

[0117] In some embodiments, the configuration related to the LCP restriction relaxation is used to relax the limitation of at least one specific LCP parameter of an LCG or LCH on the uplink transmission grant available to the terminal;

[0118] The specific LCP parameters include but are not limited to at least one of the following:

[0119] Allowed subcarrier spacing list (allowedSCS-List);

[0120] Maximum PUSCH duration (maxPUSCH-Duration);

[0121] configuredGrantType1Allowed;

[0122] List of allowed cells (allowedServingCells);

[0123] Allowed preconfigured permission list (allowedCG-List);

[0124] Allowed physical layer priority number (allowedPHY-PriorityIndex);

[0125] Allowed HARQ mode (allowedHARQ-mode).

[0126] Exemplarily, when the specific LCP parameter is allowedSCS-List, relaxing the LCP restriction means that the UE can use at least part of the radio resources of the subcarrier spacing that is not in the allowedSCS-List to transmit the first uplink data. Optionally, when the UE has multiple uplink transmission grants with subcarrier spacing that are not in the allowedSCS-List, uplink transmission grants with larger subcarrier spacing are preferentially used to reduce transmission delay.

[0127] Exemplarily, when the specific LCP parameter is maxPUSCH-Duration, relaxing the LCP restriction means that the UE may use at least part of the radio resources with a PUSCH duration greater than maxPUSCH-Duration to transmit the first uplink data. Optionally, when there are multiple uplink transmission grants with transmission lengths exceeding maxPUSCH-Duration, uplink transmission grants with shorter PUSCH durations are preferentially used to reduce transmission latency.

[0128] Exemplarily, when the specific LCP parameter is configuredGrantType1Allowed, relaxing the LCP restriction means that the UE can use at least part of the Type 2 radio resources to transmit the first uplink data.

[0129] Exemplarily, when the specific LCP parameter is allowedServingCells, relaxing the LCP restriction means that the UE can use uplink radio resources of at least some cells that are not listed in the allowed cell list to transmit the first uplink data.

[0130] Exemplarily, when a specific LCP parameter is an allowedCG-List, relaxing the LCP restriction means that the UE can use at least part of the preconfigured grants that are not listed in the allowed preconfigured grant list to transmit the first uplink data.

[0131] Exemplarily, when the specific LCP parameter is allowedPHY-PriorityIndex, relaxing the LCP restriction means that the UE can use at least part of the transmission grant whose physical layer priority does not match allowedPHY-PriorityIndex to transmit the first uplink data.

[0132] Exemplarily, when the specific LCP parameter is allowedHARQ-mode, relaxing the LCP restriction means that the UE may transmit the first uplink data using at least a portion of the transmission grant whose HARQ mode does not match the allowed HARQ mode.

[0133] In some embodiments, when determining uplink radio resources available for transmitting first uplink data (eg, time-delayed critical data), the terminal ignores restrictions on at least one parameter in the LCP parameters.

[0134] In some embodiments, before the terminal transmits the first uplink data according to the target uplink transmission grant, the uplink data transmission method 200 further includes:

[0135] The terminal receives first information from the network side device;

[0136] The terminal determines, according to the first information, to transmit the first uplink data based on the target uplink transmission permission;

[0137] The first information is used to indicate activation or enabling of the terminal to relax restrictions on a target specific LCP parameter in the at least one specific LCP parameter when the terminal determines that the target specific LCP parameter can be used to transmit the first uplink data.

[0138] Exemplarily, for any of the above-mentioned specific LCP parameters of an LCH, the network side device can explicitly or implicitly indicate whether to allow temporary relaxation of the restrictions of the specific LCP parameters, and to transmit the first uplink data of the LCH based on the non-optimal transmission permission determined by the target specific LCP parameters (i.e., the activated or enabled specific LCP parameters).

[0139] Optionally, the first information can be configured per LCH or per LCG. For example, if configured per LCG, the first information is also enabled to apply to all LCHs included in the LCG. Each specific LCP parameter corresponds to an activation or enabling indication.

[0140] In some embodiments, the target uplink transmission grant is determined from the at least one uplink transmission grant based on at least one of the following:

[0141] The order of selecting uplink transmission permissions as pre-configured or agreed upon by the protocol;

[0142] The transmission delay corresponding to each uplink transmission permission;

[0143] The transmission reliability corresponding to each uplink transmission grant.

[0144] This embodiment can ensure that the terminal preferentially selects a non-optimal uplink transmission grant having a transmission delay or reliability more suitable for transmitting the first uplink data from all non-optimal uplink transmission grants, for transmitting the first uplink data.

[0145] Illustratively, when pre-configuring or agreeing on a selection order for uplink transmission permissions, at least one of the following is referenced:

[0146] The transmission delay corresponding to each uplink transmission grant, and the transmission reliability corresponding to each uplink transmission grant.

[0147] In some embodiments, the priority of the at least one uplink transmission grant is lower than the priority of an uplink transmission grant that complies with the LCP configuration.

[0148] Exemplarily, after the terminal determines at least one uplink transmission permission based on the relevant configuration of LCP restriction relaxation, and after the terminal determines the first uplink data, it obtains an uplink transmission permission that complies with the LCP parameter restriction from the network side device, then the uplink transmission permission that complies with the LCP parameter restriction is preferentially used to transmit the first uplink data.

[0149] Therefore, in an embodiment of the present application, by relaxing the LCP parameter restrictions on the terminal's use of uplink wireless resources to transmit the first uplink data, the terminal can use uplink wireless resources that were not originally used to transmit the first uplink data (called non-optimal wireless resources) to transmit the first uplink data, so that the first uplink data obtains a transmission opportunity, improves the probability of successful transmission of the first uplink data, and reduces the transmission delay of the first uplink data.

[0150] The uplink data transmission method provided in the embodiment of the present application can be executed by an uplink data transmission device or a processing unit in the uplink data transmission device for executing the uplink data transmission method. In the embodiment of the present application, the uplink data transmission device provided in the embodiment of the present application is described by taking the uplink data transmission device executing the uplink data transmission method as an example.

[0179] The processing unit 320 is further configured to determine, according to the first information, to transmit the first uplink data based on the target uplink transmission permission;
