Dynamic data transmission method, device and storage medium

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application number 202111124350.5, filed on September 24, 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 signaling monitoring. 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.

[0155] Although SPS PDSCH can transmit PDSCH using configured resources during DRX inactivity periods, when data packet sizes fluctuate significantly, such as the Gaussian distribution of XR services, the reserved SPS PDSCH resources cannot accommodate these varying packet sizes. Remaining data in the buffer can only be transmitted after the next SPS PDSCH or DRX activation period. This waiting period inevitably results in transmission delays for services with high latency requirements, which can result in service failures.

[0156] Based on the above technical problems, the dynamic data transmission method, device and storage medium provided by the embodiments of the present disclosure carry first information through the MAC layer information carried by the first PDSCH resource, which is used to instruct the terminal to receive corresponding PDSCH data on the second PDSCH resource, thereby realizing dynamic data transmission without scheduling DCI and reducing transmission delay.

[0157] 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.

[0158] 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 terminal / user equipment (UE), such as a mobile phone. The method includes:

[0159] Step 101: Receive first information carried by MAC layer information carried by a first PDSCH resource; the first information is used to instruct a terminal to receive corresponding PDSCH data through a second PDSCH resource.

[0160] Specifically, in an embodiment of the present disclosure, when the configured or scheduled PDSCH transmission resources are insufficient to transmit data in the base station buffer, the base station sends first information carried by MAC layer information carried by the first PDSCH resource to the UE. The first information is used to instruct the terminal to receive corresponding PDSCH data through the second PDSCH resource.

[0161] In addition, even if there is no data in the base station data buffer, the first information carried by the MAC layer information carried by the first PDSCH resource can be used to pre-allocate or occupy PDSCH resources in advance or modify resource allocation information of a certain SPS PDSCH period.

[0162] Step 102: Based on the first information, receive corresponding PDSCH data through a second PDSCH resource.

[0163] Specifically, in the embodiment of the present disclosure, the terminal receives first information carried by MAC layer information carried by the first PDSCH resource.

[0164] The terminal receives corresponding PDSCH data through the second PDSCH resource indicated by the first information.

[0165] In some embodiments, the first PDSCH resource is an SPS PDSCH resource, a DCI-scheduled PDSCH resource, or a last-scheduled second PDSCH resource.

[0166] Specifically, in the embodiment of the present disclosure, the first PDSCH resource is an SPS PDSCH resource, a DCI-scheduled PDSCH resource, or a second PDSCH resource scheduled last time.

[0167] Figure 2 is one of the schematic diagrams of the dynamic data transmission principle provided by an embodiment of the present disclosure. As shown in Figure 2, the base station carries the first information carried by the MAC layer information carried by the SPS PDSCH resource. The first information is used to instruct the terminal to receive corresponding PDSCH data through the second PDSCH resource.

[0168] Figure 3 is the second schematic diagram of the dynamic data transmission principle provided by an embodiment of the present disclosure. As shown in Figure 3, the base station carries the first information carried by the MAC layer information carried by the second PDSCH resource last scheduled. The first information is used to instruct the terminal to receive the corresponding PDSCH data through the second PDSCH resource.

[0169] The embodiment of the present disclosure enhances flexibility by carrying the first information through the SPS PDSCH resource, the DCI-scheduled PDSCH resource, or the MAC layer information carried by the last scheduled second PDSCH resource.

[0170] In some embodiments, the first information is resource allocation information of the second PDSCH resource.

[0171] Specifically, in the disclosed embodiment of the present invention, the base station carries dynamic resource allocation information through the MAC layer information field in the first PDSCH resource to indicate the resource allocation information of the second PDSCH resource, that is, resource allocation time domain, frequency domain, spatial domain and other resource occupancy information. The resource allocation information can be a complete configuration of resources such as the time domain, frequency domain, and spatial domain, or a partial configuration of resources such as the time domain, frequency domain, and spatial domain. The terminal receives the PDSCH information and, at the same time, obtains the resource allocation information of the second PDSCH resource in its MAC layer information, and receives the PDSCH information according to the resource allocation information indicating the resource of the second PDSCH resource.

[0172] The embodiment of the present disclosure directly carries the resource allocation information of the second PDSCH resource in the first information, thereby improving data transmission efficiency.

[0173] Before the terminal receives corresponding PDSCH data through the second PDSCH resource, it needs to determine the first time position of the second PDSCH resource.

[0174] In some embodiments, the first time position may be a specific time slot or a time window.

[0175] Specifically, this embodiment takes a specific time window as an example to instruct the terminal to receive PDSCH data within a period of time. The specific configuration method may be one or a combination of the following methods:

[0176] Method 1: The start time of the first time position and the duration T of the first time position: The terminal continuously receives the PDSCH from the start time of the first time position for the duration T of the first time position, and then stops receiving the PDSCH.

[0177] Method 2: The start time of the first time position and the timer representing the duration: The terminal continues to receive the PDSCH from the start time of the first time position until the timer representing the duration times out, at which point the terminal stops receiving the PDSCH.

[0178] Method 3: The start time and the end time of the first time position: The terminal continuously receives the PDSCH from the start time of the first time position to the end time of the first time position.

[0179] Method 4: Start time and termination indication of the first time position. The terminal begins receiving the PDSCH from the start time slot of the first time position and performs PDSCH reception at a certain time granularity (time slot, symbol, symbol span, milliseconds, etc.), such as unit granularity or fixed granularity, until receiving a termination indication, such as dynamic scheduling termination indication information or a termination indication carried in information such as the physical layer, MAC layer, or higher layers (different from the dynamic scheduling termination indication information).

[0180] When the terminal receives PDSCH at the first time position, it may receive PDSCH at the complete first time position (here, the first time position is a time window), or it may stop PDSCH reception within the first time position (time window) through dynamic scheduling termination indication information.

[0181] The terminal receives corresponding PDSCH data in the second PDSCH resource at the first time position, which can save dynamically scheduled DCI and reduce signaling overhead.

[0182] In some embodiments, the first time position may be a prescribed time position and / or a time position indicated by a base station.

[0183] In some embodiments, the specified first time position is a time position specified by an agreement between the base station and the terminal.

[0184] For example, in the N1th time slot before or after the time slot where the Kth SPS PDSCH is located, N1 is an integer greater than or equal to 0.

[0185] For another example, the N2th time slot before or after the initial transmission HARQ-ACK feedback time slot of the Kth SPS PDSCH, where N2 is an integer greater than or equal to 0.

[0186] For another example, the N3th time slot after the successful reception of the Kth SPS PDSCH or before or after the HARQ-ACK feedback time slot where the maximum number of retransmissions is reached, where N3 is an integer greater than or equal to 0.

[0187] For another example, in the N4th time slot before or after the RTT timer is started or times out in the Kth SPS PDSCH cycle, N4 is an integer greater than or equal to 0.

[0188] Note: In the above example, the Kth SPS PDSCH can be the current SPS PDSCH period, a period after the current SPS PDSCH period, or a PDSCH period of a configured SPS PDSCH (when the terminal has multiple SPS PDSCHs configured). When N1, N2, N3, and N4 are 0, it indicates the timeslot where the Kth SPS PDSCH occurs. K, N1, N2, N3, and N4 can be specified by the protocol or configured through higher-layer signaling.

[0189] The first time position is defined by the protocol, which reduces signaling overhead.

[0190] In some embodiments, further comprising:

[0191] Send second information; the second information is used to indicate the first time position of the second PDSCH resource.

[0192] Specifically, in the embodiment of the present disclosure, the first time position is indicated by the base station. The base station sends second information to the terminal, where the second information is used to indicate the first time position where the second PDSCH resource is located.

[0193] The resource allocation information and the first time position of the second PDSCH resource can be carried in information of the same layer, such as MAC layer information, or can be carried in different signalings, such as information of different layers or different signalings of the same layer.

[0194] The resource allocation information of the second PDSCH resource and the first time position may also be carried in different layer information.

[0195] For example, the time domain information in the resource allocation information of the second PDSCH resource is symbol information in the time slot where the first time position is located, which is carried in the MAC layer information, and the first time position is configured through high-layer signaling.

[0196] The resource allocation information of the second PDSCH resource and the first time position may also be carried in the same layer information.

[0197] For example, the MAC layer information includes both the resource allocation information of the second PDSCH resource and the first time position.

[0198] In some embodiments, the indicated first time position is indicated by the base station through physical layer, MAC layer, or high-layer information.

[0199] The physical layer information includes DCI information indicating the first PDSCH resource, and the first time position is carried by DCI signaling. The DCI signaling includes activation, deactivation DCI, scheduling DCI, and non-scheduling DCI of the SPS PDSCH.

[0200] The MAC layer information includes MAC layer information carrying the first information, and the first time position is carried by the MAC information. The resource allocation information of the second PDSCH resource can be separately indicated by a MAC CE, carried in a MAC SDU, or carried.

[0201] The specific time position is configured through high-layer signaling, such as: the high-layer signaling separately configures the first time position.

[0202] The first time position is indicated by the base station, which improves the flexibility of the system.

[0203] In some embodiments, the resource allocation information is the entire set of PDSCH resource allocation information, or referred to as global allocation information.

[0204] Specifically, in the embodiment of the present disclosure, the resource allocation information is a full set of PDSCH resource allocation information, that is, the resource allocation information may be complete configuration information of resources in the time domain, frequency domain, spatial domain, and the like.

[0205] When the base station has configured SPS PDSCH for the terminal and has activated it, the terminal can receive PDSCH at the configured time slot. For the configured Nth SPS PDSCH cycle (first PDSCH resource), if the base station data buffer has not been fully transmitted through the configured PDSCH resource, in order to reduce the scheduling waiting delay of the data packets in the data buffer, the MAC layer information in the SPS PDSCH carries the resource allocation information of the second PDSCH resource. The second PDSCH resource is used to transmit part or all of the remaining data in the base station buffer, notifying the terminal to receive PDSCH at the first time position.

[0206] In the disclosed embodiment, the resource allocation information of the second PDSCH resource carried by the MAC layer information is complete resource allocation information, that is, the time domain, frequency domain, and spatial domain resource locations of the second PDSCH resource can be directly obtained according to the resource allocation information.

[0207] Resource allocation information is global allocation information, which improves system efficiency.

[0208] In some embodiments, the resource allocation information is the same as the resource allocation information carried in the dynamic scheduling DCI format 1_0, format 1_1 or format 1_2.

[0209] Specifically, in the embodiment of the present disclosure, the resource allocation information is the same as the resource allocation information carried in the dynamic scheduling DCI format 1_0, format 1_1, and format 1_2, which reduces signaling overhead.

[0210] In some embodiments, the resource allocation information includes at least one or more of the following information:

[0211] Frequency Domain Resource Allocation (FDRA) information;

[0212] Time Domain Resource Allocation (TDRA) information;

[0213] Modulation and Coding Scheme (MCS) level;

[0214] New Data Indicator (NDI);

[0215] Redundancy Version (RV);

[0216] Hybrid Automatic Repeat reQuest (HARQ) related information;

[0217] Antenna port.

[0218] In some embodiments, a new information field is added to the MAC layer information to carry resource allocation information of the second PDSCH resource.

[0219] In some embodiments, the resource allocation information is a subset of the PDSCH resource allocation information, or referred to as partial allocation information.

[0220] Specifically, in the embodiment of the present disclosure, the base station has configured the SPS PDSCH for the terminal and has activated it, so the terminal can receive the PDSCH at the configured time slot position. For the configured Nth SPS PDSCH cycle (first PDSCH resource), if the base station data buffer area has not been fully transmitted through the configured PDSCH resource, in order to reduce the scheduling waiting delay of the data packet in the data buffer area, the resource allocation information of the second PDSCH resource is carried through the MAC layer information in the SPS PDSCH. The second PDSCH resource is used to transmit part or all of the remaining data in the base station buffer area, and the terminal is notified to receive the PDSCH at the first time position.

[0221] In the embodiment of the present disclosure, the resource allocation information of the second PDSCH resource carried by the MAC layer information is a subset of the PDSCH resource allocation information, that is, the resource configuration information is configuration information associated with other resource information.

[0222] The other resources include: the K1th SPS PDSCH period, or the dynamically scheduled PDSCH of the first PDSCH resource, or the PDSCH of the designated time slot K2.

[0223] Note: The K1th SPS PDSCH may be the current SPS PDSCH period, a period other than the current SPS PDSCH period, or a PDSCH period of the configured SPS PDSCH (when the terminal is configured with multiple SPS PDSCHs).

[0224] In some embodiments, sending the first information carried by MAC layer information carried by the first PDSCH resource includes:

[0225] Multiplexing the time-frequency resource allocation information of the configured time slot where the PDSCH is located, wherein the resource allocation information of the second PDSCH resource carried by the MAC layer information is time slot information;

[0226] or,

[0227] The difference indication is performed based on the configured parameter subset of the PDSCH parameters.

[0228] Specifically, in the embodiment of the present disclosure, the specific partial configuration information can be one or a combination of the following methods:

[0229] Method 1: The time-frequency resource allocation information of the time slot where the SPS PDSCH is located is multiplexed in the dynamic resource allocation information. At the same time, the resource allocation information of the second PDSCH resource carried in the MAC information is the time slot information. Specifically, one of the following methods:

[0230] 1. First time position and / or PDSCH continuous reception time period (DynamicPDSCHduration): If the first time position is a time slot, the resource allocation information is the continuous reception time period starting from the first time position.

[0231] 2. A time window (DynamicPDSCHwindow) independent of the first time position, instructing the terminal to perform second PDSCH resource reception within the time window.

[0232] Method 2: The MAC layer information is based on the parameter configuration of the configured SPS PDSCH. The subsequent second PDSCH resource only differentially indicates one or a combination of several parameters such as frequency domain resource allocation (FDRA) information, time domain resource allocation (TDRA) information, MCS level, NDI, RV version, HARQ related information, antenna port, etc.

[0233] For example, the second PDSCH resource is based on the configured SPS PDSCH parameters, and only modifies the MCS, frequency domain resources, time domain resources, and other information. The MAC layer information uses K1, K2, and K3 bits to indicate these three information fields, respectively. The K bits of indication information in each information field can specifically indicate a numerical value, an index value of a certain configuration, or a category value of a certain configuration classification.

[0234] When the terminal receives the SPS PDSCH, it obtains the resource allocation information of the second PDSCH resource in its MAC layer information, and then receives the PDSCH information at the first time position according to the resources indicated by the resource allocation information.

[0235] Note: The configured PDSCH includes the configured SPS PDSCH, the scheduled PDSCH, and the indicated second resource PDSCH. The above method is only implemented using the configured SPS PDSCH as an example. The same method is also applicable to the scheduled PDSCH and the indicated second resource PDSCH.

[0236] In some embodiments, the first information is resource allocation indication information of the second PDSCH resource.

[0237] Specifically, in the embodiment of the present disclosure, the base station carries dynamic resource indication information through MAC layer information in the SPS PDSCH, which is used to indicate resource occupancy information such as resource allocation time domain, frequency domain, and spatial domain of the second PDSCH resource.

[0238] In some embodiments, the dynamic resource indication information includes a resource allocation information field indication and / or a modification indication of the resource allocation information field, that is, one or several resource allocation information fields in the information field of the scheduling DCI are specifically indicated through the resource allocation information field and / or one or several resource allocation information fields in the information field of the scheduling DCI are modified through the resource allocation information field.

[0239] The quantized coding of the information field of the PDSCH resource allocation by the base station through high-level signaling includes one or more combinations of the following information fields: frequency domain resource allocation (FDRA) information, time domain resource allocation (TDRA) information, MCS level, NDI, RV version, HARQ related information, antenna port and other information fields. The specific indication of the resource allocation information field is to indicate each of the above information fields in segments through Ki bits, where Ki is less than or equal to the maximum number of bits of each information field. The following is an example of representative parameters only:

[0240] 1. Divide the frequency domain resources within the currently active BWP into K1 bits. For example, existing FDRA uses RBGs to indicate resource allocation, using bit mapping or RIV value calculation. The number of K1 indications is smaller than the number of RBGs or the number of RBs calculated using the RIV value. For example, the number of RBGs or the number of RBs calculated using the RIV value is divided into K1 segments, 2^K1 segments, or a numerical segment between K1 and 2^K1. The K1 bit is the bit mapping of this K1 segment, or a specific segment within the 2^K1 segment.

[0241] 2. The current TDRA table has K2 bits, corresponding to a maximum of 2^K2 parameter configurations, where 2^K2 is less than or equal to 4.

[0242] 3. The MCS level is K3 bits, where K3 is less than or equal to 5, and is used to indicate the modulation and coding level of the PDSCH. For values ​​of K3 less than 5, the MCS table can be segmented into 2^K3 segments, with each value indicating any MCS level in the 2^K3 segment, such as the first, middle, or last MCS level in each segment, or a specific one.

[0243] 4. The number of HARQ processes is K4 bits, where K4 is less than or equal to 4 and is used to indicate the number of HARQ processes of the PDSCH, such as K4 = 1 or 2 or 3.

[0244] 5. The MAC layer carries a bit mapping table of N scheduling DCI information fields, which is used to indicate whether the corresponding information field parameters have been modified. Each scheduling DCI information field corresponds to Ki (i = 1, ..., N) bits, which are used to indicate the modification flag of an information field (modification or not), the specific value of an information field, or the modification index value of an information field.

[0245] For example, N (N is greater than or equal to 0) resource allocation information fields in the information field of the scheduling DCI are indicated by bit mapping to indicate whether the corresponding information field parameters are modified. Each scheduling DCI information field corresponds to Ki (i=1, ..., N) bits, which are used to indicate the modification flag of an information field (modification or not), or the specific value of an information field, or the modification index value of an information field, etc.

[0246] The MAC layer information carries dynamic resource indication information and also carries modification indications of one or more resource allocation information fields in the scheduling DCI, not limited to frequency domain resource allocation (FDRA) information, time domain resource allocation (TDRA) information, MCS level, NDI, RV version, HARQ related information, antenna port and other information fields.

[0247] In some embodiments, further comprising:

[0248] Send third information; the third information is used to instruct the terminal to terminate receiving corresponding PDSCH data through the second PDSCH resource.

[0249] Specifically, in the embodiment of the present disclosure, when data transmission in the base station buffer is completed, the base station sends third information (dynamic scheduling termination indication information) to the terminal to notify the terminal that there is no data transmission on the second PDSCH resource.

[0250] The dynamic scheduling termination indication information is used to instruct the terminal to terminate receiving corresponding PDSCH data through the second PDSCH resource.

[0251] The dynamic scheduling termination indication information and the second PDSCH resource allocation information may be carried in the same information or in different information.

[0252] The dynamic scheduling termination indication information can be carried in the physical layer, MAC layer, higher layer and other information. The specific methods include the following:

[0253] Method 1: Carrying information through the MAC layer. For example, when the resource allocation information of the second PDSCH resource is empty or all zeros or all ones or a specific value (configuration), the terminal stops receiving the PDSCH at the first time position; otherwise, the terminal will receive the PDSCH at the first time position according to the configuration.

[0254] Method 2: Use MAC CE to carry termination dynamic scheduling information. For example, when the MAC CE carries termination dynamic scheduling information as information 1, the terminal stops receiving PDSCH at the first time position; when the MAC CE carries termination dynamic scheduling information as information 2, the terminal will receive PDSCH at the first time position according to the configuration.

[0255] Method 3: Use physical layer (L1) signaling to carry termination dynamic scheduling information. For example, when the physical layer (L1) signaling carries termination dynamic scheduling information as information 1, the terminal stops receiving PDSCH at the first time position. When the physical layer (L1) signaling carries termination dynamic scheduling information as information 2, the terminal will continue to receive PDSCH at the first time position according to the configuration.

[0256] Method 4: Use higher-layer signaling to carry termination information for dynamic scheduling. For example, higher-layer signaling configures a timer associated with the termination information for dynamic scheduling. When the timer expires, the terminal stops receiving the PDSCH at the first time position; otherwise, the terminal continues receiving the PDSCH at the first time position according to the configuration.

[0257] The terminal stops receiving corresponding PDSCH data through the second PDSCH resource, thereby reducing terminal power consumption.

[0258] In some embodiments, FIG4 is a third schematic diagram of the dynamic data transmission principle provided by an embodiment of the present disclosure. As shown in FIG4 , if the PDSCH scheduled by the DCI in the service-specific listening window conflicts with the second PDSCH resource, that is, some or all resources (time domain, frequency domain or spatial domain) overlap, one or more of the following methods may be used:

[0259] Method 1: Only receive PDSCH resources carrying MAC layer information.

[0260] Method 2: Only receive the PDSCH resources scheduled by the DCI in the listening window.

[0261] Method 3: Receive both PDSCH resources simultaneously or receive the non-overlapping parts.

[0262] If two PDSCHs cannot be distinguished on overlapping resources, a retransmission process is triggered to further distinguish the two PDSCHs through retransmission. The complete PDSCHs can be retransmitted separately, or the overlapping PDSCHs can be retransmitted.

[0263] If two PDSCHs on overlapping resources are distinguishable in spatial resources or can be distinguished by coding, the two PDSCHs are received simultaneously.

[0264] Method 4: Both PDSCH resources are not received.

[0265] Method 5: If both PDSCHs are configured with priorities, the PDSCH with higher priority is received.

[0266] If the PDSCH scheduled by the DCI and the second PDSCH resource in the service-specific monitoring window are in different symbols of the same time slot, the terminal can receive both PDSCHs.

[0267] The disclosed embodiments avoid resource conflicts and improve reliability.
