Dynamic data transmission method, device and storage medium

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202110904389.2, filed on August 6, 2021, entitled “Dynamic Data Transmission Method, Device and Storage Medium,” which is incorporated herein by reference in its entirety. Technical Field

[0003] The present disclosure relates to the field of communication technology, and in particular to a dynamic data transmission method, device, and storage medium. Background Art

[0004] With the continuous development and improvement of the fifth generation mobile communication (5G) technology, low-latency, high-bandwidth services and scenarios for consumers have become a current priority. Extended Reality (XR) services are one of them.

[0005] Since XR services have a quasi-periodic characteristic, they are conducive to the periodicity of Semi-Persistent Scheduling (SPS). On the one hand, data can be transmitted on the pre-configured periodic Physical Downlink Shared Channel (PDSCH) without the need for scheduling requests. On the other hand, SPS scheduling can perform PDSCH transmission during the inactive period of discontinuous reception (DRX-off). Therefore, SPS scheduling in the existing technology can be applied to XR service transmission.

[0006] However, the use of existing SPS scheduling for XR service transmission has a technical defect of large transmission delay.

[0152] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0153] FIG1 is a flow chart of a dynamic data transmission method provided by an embodiment of the present disclosure. As shown in FIG1 , an embodiment of the present disclosure provides a dynamic data transmission method, the execution subject of which may be a network-side device, such as a base station. The method includes:

[0154] Step 101: Configure SPS-related dynamic resource indication information for a terminal.

[0155] Specifically, the network-side device first configures the SPS-related dynamic resource indication information for the terminal.

[0156] The terminal determines the dynamic resource indication information associated with the SPS sent by the network side device.

[0157] The dynamic resource indication information may be associated with the SPS via downlink control information (DCI) signaling, or may be associated with the SPS via resource information carried by the DCI (e.g., PDSCH resources). The dynamic resource indication information associated with the SPS may be one or more. This disclosure uses one example to illustrate the dynamic resource indication information, and multiple cases are similar and will not be described in detail here.

[0158] Optionally, the dynamic resource indication information is SPS-associated DCI signaling, and resource allocation information is carried through the DCI signaling.

[0159] Optionally, the method further includes:

[0160] The network side device configures the monitoring location information of the DCI signaling for the terminal.

[0161] Optionally, the monitoring location information includes one or more of the following information:

[0162] 1. Semi-static configuration of monitoring location information through high-layer signaling.

[0163] Optionally, when the monitoring location information includes monitoring location information semi-statically configured through higher-layer signaling, the specific method for the network-side device to configure the monitoring location information of the DCI signaling for the terminal includes:

[0164] 1. The network-side device configures the terminal with the monitoring start time for DCI signaling.

[0165] The monitoring start time also includes one or more of the following information:

[0166] (1) The time point associated with the SPS.

[0167] (2) Independent time points.

[0168] 2. The network-side device configures a listening window for the DCI signaling for the terminal.

[0169] The specific method for the network side device to configure the listening window of the DCI signaling for the terminal includes:

[0170] (1) The network side device configures the monitoring start time and duration of the monitoring window of the DCI signaling for the terminal.

[0171] The monitoring start time also includes one or more of the following information:

[0172] i. The time point associated with the SPS.

[0173] ii. Independent time points.

[0174] The duration of the listening window of the DCI signaling may be indicated in an explicit manner or in an implicit manner.

[0175] The explicit indication method includes one or more of the following:

[0176] The duration of the listening window for carrying the DCI signaling via L1 signaling;

[0177] The duration of the listening window for the DCI signaling is carried via Media Access Control (MAC) layer signaling;

[0178] The duration of the listening window of the DCI signaling is carried in higher layer signaling.

[0179] The implicit indication method includes configuring a listening timer for the terminal, so that the terminal determines the duration of the listening window of the DCI signaling according to the listening timer.

[0180] (2) The network side device configures the monitoring start time and monitoring end time of the monitoring window of the DCI signaling for the terminal.

[0181] The monitoring start time and / or monitoring end time also include one or more of the following information:

[0182] i. The time point associated with the SPS.

[0183] ii. Independent time points.

[0184] Optionally, the monitoring location information further includes one or more of the following information:

[0185] 1. The time point associated with the SPS.

[0186] The time point associated with the SPS can be understood as a relative time point.

[0187] Optionally, the time point associated with the SPS is one or more of the following time points:

[0188] (1) The time point associated with the SPS PDSCH.

[0189] Specifically, the time point associated with the SPS may be a time point associated with a start time slot / end time slot / start symbol / end symbol of the SPS PDSCH.

[0190] FIG2 is a schematic diagram of one of the SPS PDSCH enhancement solutions provided by an embodiment of the present disclosure. As shown in FIG2 , for example, the DCI signaling is monitored starting at a certain time offset after the start time slot of the SPS PDSCH.

[0191] (2) The time point associated with the Hybrid Automatic Repeat reQuest Acknowledgement (HARQ-ACK) of the SPS PDSCH.

[0192] Specifically, the time point associated with the HARQ-ACK of the SPS PDSCH may be a time point associated with the start time slot / end time slot / start symbol / end symbol of the SPS PDSCH.

[0193] As shown in FIG. 2 , for example, at a certain time offset after the end time slot of the HARQ-ACK of the SPS PDSCH, the DCI signaling starts to be monitored.

[0194] (3) The time point associated with the expiration of the Round Trip Time (RTT) timer of the SPS PDSCH.

[0195] Specifically, the time point associated with the expiration of the RTT timer of the SPS PDSCH may be a time point associated with the start time slot / end time slot / start symbol / end symbol of the SPS PDSCH RTT timer expiration.

[0196] As shown in FIG. 2 , for example, at a certain time offset after the start symbol of the SPS PDSCH RTT timer expires, the DCI signaling starts to be monitored.

[0197] Optionally, the time unit of the offset value of the monitoring position information relative to the time point is a time slot, a span, a symbol or a millisecond.

[0198] Specifically, a time offset from the above time point may be configured, and the time unit may be ms, time slot, or symbol.

[0199] For example, the start time can be specified in units of the start symbol of a timeslot or a symbol position within a timeslot. The listening window duration can be a number of consecutive timeslots, a number of consecutive symbols within a timeslot, or a fixed number of symbols within a number of consecutive timeslots. The timer length can be specified in milliseconds, timeslots, or symbols.

[0200] It should be noted that the start time may be the time offset between the time points associated with the start time slot / end time slot / start symbol / end symbol of the SPS PDSCH or the HARQ-ACK of the SPS PDSCH or the RTT timer timeout of the SPS PDSCH, etc., and may be a value greater than or equal to 0, that is, the above-mentioned time point as the start time, or an offset time position after the above-mentioned time point; or a value less than 0, that is, an offset time position before the above-mentioned time point.

[0201] Alternatively, the start time may be a time offset between time points associated with the start time slot / end time slot / start symbol / end symbol of the SPS PDSCH or HARQ-ACK of the SPS PDSCH or RTT timer timeout of the SPS PDSCH, and may be a value greater than or equal to 0, but the start time point may be the above-mentioned time point as the start time, or an offset time position after the above-mentioned time point, or an offset time position before the above-mentioned time point.

[0202] 2. Independent time point.

[0203] The independent time point may be understood as a specific time point, or a specific time point determined by the terminal through calculation. The independent time point may be unrelated to the SPS.

[0204] For example, the start time may be an absolute time, which is a specific time obtained by the terminal through calculation based on the system frame number (SFN) by configuring the periodicity and the offset.

[0205] For example, the time slot number of the start time meets the following conditions:

[0206]

[0207] Among them, n f is the frame number, is the time slot number under subcarrier μ, is the number of time slots contained in the next subframe of subcarrier μ, ks is the monitoring period, and Os is the offset value.

[0208] 2. Monitoring position information dynamically adjusted according to the first information.

[0209] The base station configures first information for the terminal, which is used to dynamically indicate changes in monitoring position information, for example, dynamically indicating one or more of the size of the monitoring window, the monitoring start position, and the monitoring end position.

[0210] For example, it indicates the time for the terminal to continue monitoring after monitoring the dynamic scheduling DCI.

[0211] The first information may be carried through L1 signaling, MAC signaling, or higher layer signaling.

[0212] For example, the first information may be a listening timer or duration, or may be indicative signaling information, or may be a reference signal. Taking the listening timer as an example, when the listening timer has not timed out, the terminal may continue to monitor the service-specific DCI. When a service data packet is transmitted at the end of the listening window due to delay jitter, the data packet must wait for the next listening window or listening opportunity to be transmitted due to the lack of subsequent listening opportunities. Configuring a listening timer helps reduce the transmission delay caused by delay jitter.

[0213] Optionally, the monitoring occasion (MO) of the DCI signaling may be one of the following:

[0214] (1) It can be configured through the existing search space set configuration method.

[0215] For example, configure parameters such as the monitoring period and offset, and the frequency domain aggregation level (AL).

[0216] (2) You can also configure related configurations on a single MO (this can be at the timeslot level or the span level).

[0217] (3) The index value of the search space can also be associated.

[0218] Optionally, the time unit of the MO of the DCI signaling may be a time slot or a span, and the monitoring opportunity may be configured by an index value of an associated search space.

[0219] Step 102: Use the dynamic resource indication information to perform dynamic data transmission indication during a discontinuous reception (DRX) inactive period.

[0220] Specifically, after the network side device configures the SPS-related dynamic resource indication information for the terminal, the network side device uses the dynamic resource indication information to perform dynamic data transmission indication during DRX-off.

[0221] After determining the SPS-associated dynamic resource indication information sent by the network-side device, the terminal performs dynamic data reception according to the dynamic resource indication information during DRX-off.

[0222] Optionally, it also includes:

[0223] The network side device sends a dynamic transmission indication to the terminal, where the dynamic transmission indication is used to instruct the terminal to perform dynamic data transmission.

[0224] The base station instructs the terminal to perform subsequent dynamic transmission instructions, indicating that the terminal can perform dynamic scheduling DCI monitoring after receiving the SPS PDSCH; otherwise, the terminal performs normal SPS PDSCH reception.

[0225] Optionally, the dynamic transmission indication is indicated through L1 signaling, Media Access Control Control Element (MAC CE) signaling, energy saving signal or higher layer signaling.

[0226] For example, when the terminal receives the following indication, and the base station configures the monitoring position information of the dynamically scheduled DCI, it indicates that the terminal can perform the monitoring behavior of the dynamically scheduled DCI after receiving the SPS PDSCH; otherwise, the terminal performs the normal SPS PDSCH reception. The specific indications are one or more of the following combinations:

[0227] 1. The terminal capability supports monitoring of dynamically scheduled DCI after receiving SPS PDSCH.

[0228] 2. Instruction is given through scheduling DCI (such as SPS PDSCH activation DCI, SPS PDSCH retransmission DCI, etc.).

[0229] 3. The MAC CE indicates that the terminal can monitor the dynamic scheduling DCI after receiving the subsequent SPS PDSCH.

[0230] 4. The high-level signaling is configured with a switch, indicating that it can support the monitoring of dynamic scheduling DCI after SPS PDSCH reception.

[0231] 5. The energy-saving signal indicates the monitoring behavior of the dynamic scheduling DCI after the subsequent SPS PDSCH reception.

[0232] It should be noted that the combination of several indications refers to the simultaneous existence of several of the above indications, such as terminal capability and scheduling DCI indication, or terminal capability and high-layer signaling configuration switches, etc., which will not be repeated here.

[0233] Optionally, if the SPS PDSCH does not complete the data transmission in the buffer of the network-side device, the network-side device will instruct the terminal to perform dynamic scheduling DCI detection after the SPS PDSCH.

[0234] After receiving the dynamic transmission indication sent by the network side device, the terminal starts from the monitoring start position configured by the network side device and continuously monitors the dynamically scheduled DCI with a monitoring granularity of MO. That is, it receives dynamic data according to the dynamic resource indication information during DRX-off.

[0235] The dynamic data transmission method provided by the embodiment of the present disclosure completes the transmission of data services with large differences in data size through dynamic scheduling to assist SPS PDSCH transmission within DRX-off. When the data packet is large but the reserved SPS PDSCH resources are insufficient, it assists in transmitting the data packet without waiting for the next SPS PDSCH or DRX activation period. When the data packet is small, the periodicity of the reserved SPS PDSCH resources and the dynamic scheduling resources can be used to complete the data transmission, thereby reducing the transmission delay.

[0236] Optionally, it also includes:

[0237] A stop indication is sent to the terminal, where the stop indication is used to instruct the terminal to stop dynamic data transmission.

[0238] Specifically, when a specific condition is met or the base station sends an instruction, the terminal stops monitoring DCI in the monitoring window of the dynamically scheduled DCI.

[0239] For example, when the terminal completes data packet transmission, in order to avoid unnecessary DCI monitoring, the base station side instructs the terminal to stop monitoring DCI in the monitoring window of dynamically scheduled DCI.

[0240] Optionally, the stop indication is carried through L1 signaling, medium access control element MAC CE signaling, energy saving signal or higher layer signaling.

[0241] FIG3 is a second schematic diagram of an SPS PDSCH enhancement solution provided by an embodiment of the present disclosure. As shown in FIG3 , for example, when a specific condition is met or the base station sends a stop instruction, the terminal stops monitoring DCI in the monitoring window of the dynamically scheduled DCI. Specifically, the conditions may be one or a combination of the following:

[0242] 1. The terminal receives a dummy scheduling DCI with empty scheduling information.

[0243] 2. The terminal times out based on the configured timer. This timer and the listening window are independent of each other.

[0244] 3. The terminal receives the SPS PDSCH release DCI.

[0245] It should be noted that the several combinations here refer to the simultaneous existence of the above-mentioned several indications, and the monitoring of the dynamic scheduling DCI can be stopped when any one of them is met.

[0246] For example, when a monitoring timer and a scheduling DCI with empty scheduling information are configured at the same time, monitoring of the dynamic scheduling DCI can be stopped if either one satisfies the conditions, which will not be described in detail here.

[0247] In the embodiment of the present disclosure, stopping monitoring DCI may indicate that the terminal skips monitoring, or the terminal enters sleep.

[0248] The dynamic data transmission method provided by the embodiment of the present disclosure stops monitoring the dynamic scheduling DCI when specific conditions are met, and can also reduce signaling overhead and improve spectrum utilization.

As shown in FIG4 , for DCI format 2_6 carrying the listening window and / or listening start position for dynamically scheduled DCI, one or more listening opportunities can be configured during the DRX inactive period to indicate whether to monitor dynamically scheduled DCI after one or more subsequent SPS PDSCHs. The listening position for DCI format 2_6 can be sent after the SPS PDSCH.

[0251] Optionally, taking the start time before the reference time point as an example, if the terminal monitors the dynamic scheduling DCI before the SPS PDSCH, the terminal may perform one of the following actions:

[0252] 1. If the PDSCH indicated by the dynamic scheduling DCI is located after the SPS PDSCH, the terminal can receive the dynamically scheduled data information according to the PDSCH indicated by the dynamic scheduling DCI after the SPS PDSCH or the HARQ-ACK of the SPS PDSCH or the RTT timer of the SPS PDSCH expires.

[0253] 2. If the PDSCH indicated by the dynamic scheduling DCI is located before the SPS PDSCH, or overlaps with the SPS PDSCH time slot, the terminal can receive the dynamically scheduled data information according to the PDSCH indicated by the dynamic scheduling DCI without receiving the SPS PDSCH, or can receive non-overlapping PDSCH based on the SPS PDSCH.

[0254] The reference time point may be a time point associated with a start time slot / end time slot / start symbol / end symbol of an SPS PDSCH or HARQ-ACK of an SPS PDSCH or expiration of an RTT timer of an SPS PDSCH.
