Description

Technical Field

[0001] This application relates to the field of data processing technology, and in particular to a data processing method, terminal, storage medium, and computer program product. Background Technology

[0002] XR (Extended Reality) systems have two prominent characteristics: the integration of information from the real and virtual worlds, and real-time interactivity. XR systems employ multi-channel interaction; humans possess multiple sensory perception capabilities, and the virtual environment can provide users with a truly immersive sensory experience. Gestures, body postures, voice, and even eye-viewpoint capture can all serve as interaction methods within augmented reality systems. Furthermore, tactile, olfactory, auditory, and force feedback can be used as outputs, thereby achieving a combination of multi-channel augmented reality interaction and user intent.

[0003] In existing data communication processes, when a data packet arrives at the Packet Data Convergence Protocol (PDCP) layer, a discard timer is started. If the packet is not successfully transmitted or received by the other end before the timer expires, it is discarded. Existing data communication or data discarding mechanisms consider the error rate and latency of individual packets, focusing on singular and fixed information. This results in low flexibility in data communication and makes it difficult to meet the data communication needs of different types of services, such as XR services. Summary of the Invention

[0184] In embodiments of this application, when the terminal performs communication and / or data discarding of data and / or data streams based on information comparing the efficiency and / or repetition rate of data in the first data stream with a fifth threshold, it further performs the following steps: obtaining at least one of the repetition rate and efficiency of data in the first data stream from the application layer; sending the obtained repetition rate and / or efficiency to the base station through access layer (AS) signaling; and informing the base station of the total data volume of a stream.

[0185] For example, in the embodiments of this application, the terminal can decode Quick UDP Internet Connections (QUIC) messages, Real-time Transport Protocol (RTP) headers, or Non-Access Stratum (NAS) signaling to obtain the duplication rate, effective data rate, etc. Alternatively, even uplink (UL) redundancy can be sent to the base station through the core network.

[0186] It should be noted that, in the embodiments of this application, the terminal sends the repetition rate and / or efficiency of the data in the first data stream to the base station via AS signaling. Specifically, this can be done through a Media Access Control (MAC) Control Element (MAC CE), such as Buffer Status Reporting (BSR), Delay Status Reporting (DSR), or a new MAC CE, Radio Resource Control (RFC) signaling, or Downlink Control Information (DCI).

[0194] In embodiments of this application, based on the various optional methods included in the communication and / or data discarding of execution data and / or data streams described above, the terminal may also perform at least one of the following:

[0195] Based on the instructions from the application layer and / or the AS layer signaling, or the information carried in the data packet header, determine whether to discard all data in the first data and / or the data in the corresponding stream when the remaining time of at least one data in the first data stream is greater than the sixth threshold or equal to zero; wherein, the value of the sixth threshold is less than the first threshold or the second threshold;

[0196] Based on the instructions from the application layer and / or the AS layer signaling, or the information carried in the data packet header, determine whether all data of the N data and / or the N data stream should be discarded when the time difference between the transmission and / or reception of N data and / or the remaining time difference is greater than the seventh threshold or equal to zero.

[0197] Based on the instructions from the application layer and / or the AS layer signaling, or the information carried in the data packet header, determine whether all other data in the stream containing the first data should be discarded when the success rate and / or repetition rate of the first data or the data in the stream containing the first data is greater than the fifth threshold.

[0198] It should be noted that, in the embodiments of this application, the AS layer signaling includes at least one of RRC signaling, Packet Data Convergence Protocol (PDCP) control signaling, RLC control signaling, MAC CE, and DCI.

[0199] The following explains the scheme for the terminal to perform communication and / or data discarding of data and / or data streams based on different timer durations corresponding to data and / or data streams of different importance, as well as status indications sent by the base station and / or status information determined by the terminal.

[0200] In the embodiments of this application, the timer durations corresponding to the same feature information data in different states may be the same or different, and the timer durations corresponding to the same state are the same; wherein, the state includes at least one of the following: data transmission success rate, data transmission time difference under data transmission rate.

[0201] It should be noted that, in the embodiments of this application, the duration of each timer can be indicated to the terminal by the application layer of the terminal and / or configured to the terminal by the network. The specific duration of the timers is not limited in the embodiments of this application.

[0202] For example, in the embodiments of this application, the timer duration corresponding to data with importance of 0 in different states is t1;

[0203] The timer duration for data with importance p is t2 regardless of the state.

[0204] The timer duration for data with importance q is t3 regardless of the state.

[0205] The timer duration for data with importance 'r' is t4 regardless of the state.

This may include: activating at least one timer duration based on the status indication or status information, and scheduling and / or discarding data of corresponding priority when each timer duration expires.

[0211] In the embodiments of this application, at least one of the PDU subset, QoS substream, and logical subchannel corresponds to a timer duration.

[0212] In embodiments of this application, the status indication includes the current allowed data length to be cached by the terminal. Based on the status indication, the terminal activates at least one timer duration and schedules and / or discards data of corresponding priority when each timer duration expires. This includes: selecting at least one timer duration to activate based on the data length and in ascending order of data priority, and determining the non-reserved length or reserved length corresponding to data of different priorities; when the first timer duration expires, scheduling and / or discarding the data of the first priority based on the non-reserved length or reserved length corresponding to the data of the first priority; wherein the first timer length is any activated timer length, and the data of the first priority corresponds to the first timer length.

[0213] It is understood that, in the embodiments of this application, the terminal discards data in a certain size according to the current allowed cached data length and in order of data priority from low to high. For example, data with priority a retains data of length s1 or discards data of length s2; data with priority b retains data of length s3 or discards data of length s4; data with priority c retains data of length s5 or discards data of length s6, and so on.

[0214] In embodiments of this application, in order for the base station to determine the aforementioned status indication, the terminal may further perform at least one of the following steps:

[0215] Report channel quality and / or buffer status to the base station so that the base station can determine the status indication;

[0216] The remaining time of the first data and the information of the first threshold comparison are reported to the base station so that the base station can determine the status indication;

[0217] The remaining time of the first data and the information of the comparison with the second threshold are reported to the base station so that the base station can determine the status indication;

[0218] Report information on the time difference between transmission and / or reception of N data points and the comparison with the third threshold to the base station so that the base station can determine the status indication;

[0219] Report information to the base station regarding the remaining time difference for sending and / or receiving N data points and the comparison with the fourth threshold, so that the base station can determine the status indication;

[0220] The base station is informed of the effectiveness and / or repetition rate of the data in the first data stream and the comparison with the fifth threshold, so that the base station can determine the status indication.

[0221] In the embodiments of this application, the aforementioned status information terminal can be obtained in at least one of the following ways:

[0222] Retrieved from the application server;

[0223] Determined based on user experience;

[0224] Determined based on experience quality information;

[0225] Determined based on data transmission error rate and / or channel quality.

[0226] In embodiments of this application, the terminal may also periodically adjust at least one of the timer duration, status indication, and status information. Based on this, the terminal may also perform the following steps: sending a load response request and / or a timer duration adjustment request to the base station, and receiving current load information and / or timer duration adjustment information from the base station; adjusting the status indication based on the current load information, and / or adjusting the timer duration based on the timer duration adjustment information.

[0227] In the embodiments of this application, if the terminal performs data discarding, it can also send packet loss information to the base station after performing data discarding;

[0228] The packet loss information includes at least one of the following:

[0229] The sequence number of the discarded data;

[0230] The sequence number of the first data item discarded;

[0231] The amount of data discarded;

[0235] Instructions on whether the PDU set containing the discarded data requires integrity processing;

[0236] The sequence number of one or more PDU sets containing the discarded data;

[0237] The index of the discarded data within its PDU set;

[0238] The sequence number of the first or last discarded data in the PDU set;

[0239] Reasons for discarding data.

[0240] In the embodiments of this application, when the terminal performs data and / or data stream communication and / or data discarding, if a preset condition is met within a preset time period, then neighbor cell measurement and / or neighbor cell handover are performed.

[0241] The preset conditions include at least one of the following:

[0242] The status information is higher than the first threshold;

[0243] The duration of the activated timer is less than the second threshold;

[0244] The length of the cached data is less than the third threshold.

[0245] In the embodiments of this application, the terminal can perform data and / or data stream communication, and the process of the terminal transmitting at least two data items is described in detail below.

[0246] In embodiments of this application, the UL grant received by the terminal transmits only at least two data points whose transmission delay difference is less than a threshold; or, the received UL grant preferentially transmits at least two data points whose transmission delay difference is less than a threshold; wherein, the at least two data points come from at least two streams.

[0247] It should be noted that, in the embodiments of this application, at least two data points can be data from at least two logical channels, data from at least two frames, or data from at least two PDU sets. This ensures that data with time synchronization relationships has guaranteed UL resources for transmission. Specific data is not limited in the embodiments of this application.

[0248] In embodiments of this application, UL Grant prioritizes transmitting at least two data items with a transmission delay difference less than a threshold, and the method further includes:

[0249] If the size of the UL grant is greater than at least two data sets whose transmission delay difference is less than a threshold, the remaining resources will be prioritized for transmitting data with the same PDU set and / or stream.

[0250] Alternatively, if the size of the UL grant is greater than at least two data with a transmission delay difference less than a threshold for the data to be transmitted, the remaining resources will preferentially transmit data with a higher logical channel priority, data with a remaining time less than the configured threshold, logical information or / and data of a flow with a data rate lower than a certain threshold.

[0251] It can be understood that in the embodiments of the present application, if the size of the UL grant is greater than at least two data with a transmission delay difference less than a threshold for the data to be transmitted, the remaining resources will preferentially transmit data of the same PDU set and / or flow, so as to ensure that the data of the same PDU set or flow is transmitted first, and ensure the integrity of the data transmission of the PDU set or flow. Ensure the formation of the same picture; if the size of the UL grant is greater than at least two data with a transmission delay difference less than a threshold for the data to be transmitted, the remaining resources will preferentially transmit data with a higher logical channel priority, data with a remaining time less than the configured threshold, logical information or / and data of a flow with a data rate lower than a certain threshold, so as to ensure that packets with a higher logical channel priority, packets with a remaining time less than the configured threshold, and logical information or / and packets of a flow with a data rate lower than a certain threshold are transmitted first.

[0252] In the embodiments of the present application, the terminal may also perform the following steps: receiving the transmission ratio and / or priority corresponding to data with different remaining time thresholds configured by network signaling and / or data with a transmission delay difference less than the threshold between at least two data; when there are data corresponding to multiple different remaining time thresholds, loading the data according to the priorities and transmission ratios corresponding to the different remaining time thresholds notified by the network; or, when there are data corresponding to multiple different transmission delay differences less than the threshold, loading the data according to the priorities and transmission ratios corresponding to the different transmission delay differences less than the threshold notified by the network.

[0253] Exemplarily, in the embodiments of the present application, the remaining time thresholds are t0, t1, t2.., tm, where t0 < t1 < t2... < tm, then the priority corresponding to t0 > the priority corresponding to t1 > the priority corresponding to t2 >... > the priority corresponding to tm; transmission ratio: t0--a%, t1--b%, t2--c%.., tm--m% (a > b > c >... > m). When there is no transmission ratio and only priorities, the terminal first finishes loading the data corresponding to t0, and then loads the data corresponding to t1, etc.

[0254] In an embodiment of the present application, the terminal may further perform the following steps: receiving data of thresholds of remaining time corresponding to different logical channel priorities configured by network signaling and / or transmission ratios and / or priorities corresponding to data with a transmission time delay difference less than a threshold between at least two data; when there are data corresponding to multiple different thresholds of remaining time, loading the data according to the priorities and transmission ratios corresponding to different thresholds of remaining time corresponding to different logical channel priorities informed by the network; or: when there are data with multiple different transmission time delay differences less than a threshold, loading the data according to the priorities and transmission ratios corresponding to different thresholds of transmission time delay differences less than corresponding to different logical channel priorities informed by the network.

[0255] Exemplarily, in an embodiment of the present application, the priorities of logical channels are Plg0 > Plg1 > Plg2 >... > Plgm; the thresholds of remaining time are t0, t1, t2.., tm; t0 < t1 < t2... < tm, the priority corresponding to t0 > the priority corresponding to t1 > the priority corresponding to t2 >... > the priority corresponding to tm, transmission ratio: t0--a%, t1--b%, t2--c%.., tm--m% (a > b > c >... > m).

[0256] In an embodiment of the present application, if the remaining time of multiple data is the same, the data with a higher priority and / or importance level corresponding to the data is sent first;

[0257] If the remaining time of multiple data is different, the data with the smallest remaining time is sent first;

[0258] If the remaining time of multiple data is different, the data with a remaining time less than the lowest threshold is sent first;

[0259] If the remaining time of multiple data is different, the data with a remaining time less than the lowest threshold or the smallest remaining time that meets certain conditions is sent first;

[0260] Among them, the above conditions include that the priority and / or importance of the sent data is higher than and / or equal to a certain threshold.

[0261] It can be understood that in an embodiment of the present application, the above sending rules for the case where the remaining time of multiple data is the same or different can ensure flexible sending of data according to the priority of services and the importance of data, and can send the data of services with low delay requirements in a timely manner.

[0262] Based on the above content, it can be seen that the technical solution provided by the embodiment of the present application improves the flexibility of data communication and can meet the data communication requirements under various types of services by performing communication and / or data discarding of data and / or data streams according to the characteristic information of data and / or the streams where the data is located.
