Description

Technical Field

[0001] This application relates to the field of wireless communication technologies, and in particular, to a method and device for configuring data transmission resources. Background Art

[0002] The physical uplink shared channel (PUSCH) scheduling of configured grant (CG) periodically allocates the resources of PUSCH to a specific terminal device (UE). There are two ways to transmit the configured CG PUSCH: one is CG PUSCH type 1, where all the resources of the transmission grant are provided by RRC. The UE stores this configuration and uses it as the grant configuration when there is uplink data transmission. The other is CG PUSCH type 2. The RRC layer configures information such as the period of CG PUSCH and the HARQ sequence number, and then the physical downlink control channel PDCCH gives an indication to activate or deactivate the configuration. The PDCCH for activating or deactivating CG PUSCH contains the resources occupied by PUSCH in terms of time and frequency, as well as the time position of the first CG PUSCH. After the UE obtains the activation information, it can use the CG PUSCH resources.

[0003] Based on the realization that multiple PUSCH transmission opportunities are included within one CG PUSCH period, the number of PUSCHs occupied by a data packet is determined by the size of the data packet. For example, the arrival of packets for extended reality (XR) services is periodic, but the actual arrival time of the packets may experience jitter, resulting in random arrival within the jitter time window. In addition, the size of XR data packets varies over time. When multiple CG PUSCH transmission opportunities are configured in each CG period, since the semi-statically configured CG resources cannot well match the dynamic frame size, the CG resources in the CG period may be over-allocated to avoid delays caused by frequent requests for additional resources. To improve resource utilization, it is possible to consider dynamically reclaiming unused resources. Alternatively, in some cases, the CG resources in the CG period cannot meet the XR data transmission requirements, and additional PUSCH resources need to be allocated to the device. Summary of the Invention

[0043] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0044] The following will describe in detail the technical solutions provided by each embodiment of the present application in conjunction with the drawings.

[0045] Figure 1 Schematic diagram of the scheduling of the CG PUSCH type 2 in the prior art. After the UE obtains the PDCCH for activating the CG PUSCH, it periodically occupies the CG PUSCH resources to send uplink information.

[0046] Figure 2 Schematic diagram of configuring multiple data transmission opportunities within one period of the CG PUSCH. The arrival of packets for extended reality (XR) services is periodic, but the actual arrival time of the packets may experience jitter, resulting in their random arrival within the jitter time window. Figure 2This is an example. In this example, the first jitter time window starts at time t0, within which the XR data packet can arrive between t0 and t3. In the figure, the XR data packet arrives at time t1. The next XR data packet arrives after time P, and the arrival time of the next XR data packet can be at any time within the jitter time window between t4 and t7. For example, in the figure, the next XR data packet actually arrives at time t7. To meet the characteristics of the arrival time jitter of the XR service, multiple data transmission opportunities can be configured within a period P of the CG PUSCH to meet the requirement of timely transmission after the service packet arrives.

[0047] Figure 3 This is a schematic diagram of the transmission timing data for multiple data transmission opportunities within a period of the CG PUSCH. The packet size of XR varies with time. Taking AR / VR 30Mbps as an example, the maximum packet size is 93750 bytes, and the minimum packet size is 31250 bytes. Based on the implementation of multiple PUSCH transmission opportunities within a period of the CG PUSCH, the number of PUSCHs occupied by the data packet is determined by the size of the data packet. As shown in the figure, within the first period of the CG PUSCH, the XR data packet occupies 3 PUSCHs to transmit TB1, TB2, and TB3 respectively. In the next period of the CG PUSCH, the XR data packet occupies 1 PUSCH to transmit TB4.

[0048] Figure 4 This is the indication of the timing usage of the resources for multiple data transmission opportunities within a period of the CG PUSCH. In this example, there are four transmission opportunities within a period of the CG PUSCH resources configured for the UE. According to the actual resource occupancy of the XR data in each period, the UE can send a "resource usage indication" of its own usage of these resources to the gNB. For the unused resources, the gNB can allocate them to other UEs to improve the utilization efficiency of the uplink resources.

[0049] Figure 5Schematic diagram of CG PUSCH recycling resource reallocation. As shown in the figure, it is the resource usage of CG PUSCH allocated by gNB to UE1 within one period. Slots #(n + 3) to #(n + 15) are the PUSCH transmission opportunities within this period, and there are PUSCH resources configured for UE1 on each PUSCH transmission opportunity. The actual XR data of UE1 occupies the resources of Slots #(n + 3) to #(n + 5) within this period. If the "resource usage indication" is sent in Slot #(n + 3), it indicates that the CG PUSCH resources from Slot #(n + 6) to #(n + 15) can be recycled. gNB reallocates the recycled resources to other UEs, and other UEs need to obtain the scheduling indication before using the corresponding resources. However, gNB only obtains the CG resource release information of UE1 in Slot #(n + 3). UE2 is far from gNB, and even if gNB sends a scheduling indication to UE2 in Slot #(n + 3), it will only reach UE2 in Slot #(n + 13). Therefore, only Slots #(n + 14) and #(n + 15) in the CG resources released by UE1 can be reused by UE2. For UE3, which is even farther from gNB, none of the CG resources released by UE1 can be notified to gNB and allocated to UE3 before they can be occupied.

[0050] Considering the time required from gNB obtaining the "resource usage indication" sent by the UE to gNB scheduling the unused CG PUSCH resources of the UE to other UEs, this time period includes any of the following combinations:

[0051] The first type: The time for the UE to determine and process the "resource usage indication". The length of this time period depends on the processing speed and scheduling speed of the UE.

[0052] The second type: The time for gNB to parse the "resource usage indication" and the processing time for gNB to allocate the "recycled resources" to other UEs. The length of this time period depends on the processing speed and scheduling speed of gNB.

[0053] The third type: The air propagation delay of the "resource usage indication" information. When the communication distance is short, the air propagation delay of the "resource usage indication" is small and can be ignored. In non-terrestrial communication systems such as terrestrial-air communication or satellite communication, the information propagation delay is long. The indication of the unused CG PUSCH resources of the UE needs to experience a period of time to reach gNB and be known by gNB, and then gNB allocates the unused CG PUSCH resources to other UEs. The air propagation delay of this allocation information also needs to experience the air propagation delay.

[0054] It should be noted that any combination includes the case of one type.

[0055] InFigure 5 In the example of Figure 5 , if the CG resources released by UE1 cannot be reallocated to other UEs, then UE1 sending a "resource usage indication" does not serve the purpose of improving the uplink resource usage efficiency. Instead, it causes UE1 to send invalid information, reducing the feedback resource efficiency and the power efficiency of UE1.

[0056] Figure 6 This is a flowchart of an embodiment of the method of this application. This application proposes a method for configuring data transmission resources, including the following steps 110 to 130:

[0057] Step 110: Determine the time period configuration information, where the characteristic duration indicated by the time period configuration information is the first duration, the second duration, the third duration, or the sum of any of them; the first duration corresponds to the processing duration of the resource indication information, the second duration corresponds to the transmission duration of the resource indication information, and the third duration corresponds to the information transmission duration of the scheduled target resource.

[0058] The first duration corresponding to the processing duration of the resource indication information means that the first duration is a characteristic value preset according to the processing duration of the resource indication information and is equivalent to the processing duration of the resource indication information. Preferably, the processing duration of the resource indication information is not higher than the first duration.

[0059] The second duration corresponding to the transmission duration of the resource indication information means that the second duration is a characteristic value preset according to the transmission duration of the resource indication information and is equivalent to the transmission duration of the resource indication information. Preferably, the resource indication transmission duration is not higher than the second duration.

[0060] The third duration corresponding to the information transmission duration of the scheduled target resource means that the third duration is a characteristic value preset according to the information transmission duration of the scheduled target resource and is equivalent to the information transmission duration of the scheduled target resource. Preferably, the information transmission duration of the scheduled target resource is not higher than the third duration.

[0061] Step 120: Determine the recycling indication information, where the recycling indication information is used to indicate whether to transmit the resource indication information.

[0062] Whether UE1 sends a "resource usage indication" is configured by the gNB. The gNB determines the configuration information for UE1 based on the resources and power used by UE for sending the "resource usage indication" and the reallocation efficiency of the recycled resources. For example, if the gNB determines that the unused resources recycled from UE1 do not need to be allocated to other UEs, or the reuse of the recycled resources cannot compensate for the cost of UE1 sending the "resource usage indication", then it can configure UE1 not to send the "resource usage indication".

[0063] Preferably, based on the value of the characteristic duration, determine whether to transmit the resource indication information.

[0064] Preferably, according to the recycling indication information, determine the valid time range for transmitting the resource indication information.

[0065] Step 130: Determine the resource indication information, which is used to indicate the release of the target resource or request additional PUSCH resources. The target resource is the configured PUSCH resource and is in a preset time period after the time point obtained by accumulating the characteristic duration at the end time of the resource indication information.

[0066] One cycle of the configured PUSCH resource includes at least two PUSCH transmission opportunities.

[0067] The "resource usage indication" sent by UE1 is used to determine which of the CG PUSCH resources allocated to UE1 are to be released. Alternatively, the "resource usage indication" sent by UE1 is used to determine to request additional PUSCH resources in addition to the CG PUSCH resources.

[0068] For example, the time difference between the time position of the "resource usage indication" and the time position of the recycled CG PUSCH resource is at least not less than the sum of T1 and T2:

[0069] T1: The time for the gNB to process the "resource usage indication". Optionally, it also includes the processing time for the gNB to allocate the "recycled resources" to other UEs.

[0070] T2: The time offset. It is indicated by the gNB to the UE and includes the air propagation delay T of the "resource usage indication" information 21 , and the air propagation delay T of the scheduling indication 22 . T 21 reflects the time for the gNB to obtain the "resource usage indication", and T 22 reflects the time for the gNB to allocate the recycled resources to other UEs. The gNB indicates to UE1 that T2 = T 21 +T 22 , or the gNB indicates T 21 and T 22 to UE1 separately. As Figure 8 shown, T 21 corresponds to the second duration, and T 22 corresponds to the third duration, reflecting the time required for the gNB to allocate the recycled resources to any one device in the target device group.

[0071] In particular, when any one of T2, T 21 , or T 22 is a preset value, it means that UE1 does not need to send the "resource usage indication".

[0072] Again, the "resource usage indication" indicates the CGPUSCH resources released within a pre-configured time period after the basic time offset.

[0073] It should be noted that the above steps are for network entities in a wireless communication system, including terminal-side devices, network-side devices, or other intermediate devices; the above steps can also be used for a service device that provides information processing for the network entity device; the above steps can also be used for any device, system, subsystem, circuit, chip, or software entity that provides information reception, transmission, identification, and processing for terminal-side devices or network-side devices.

[0074] Figure 7 The flowchart of the embodiment of the method of the present application for a network-side device. The method according to any one of the first aspects of the present application, for a network-side device, includes the following steps 210 to 240:

[0075] Step 210: Send a recycling indication message, where the recycling indication message is used to indicate whether to transmit a resource indication message.

[0076] The recycling indication message is used to indicate whether the terminal-side device UE sends the resource indication message.

[0077] Step 220: Send time period configuration information, where the characteristic time periods indicated by the time period configuration information include a first time period, a second time period, a third time period, or the sum of any of them; the first time period corresponds to the processing time of the resource indication message, the second time period corresponds to the transmission time of the resource indication message, and the third time period corresponds to the information transmission time of the scheduled target resource.

[0078] The processing time of the resource indication message includes the time for the network side to identify and determine the resource indication message, and / or the time for the terminal side to determine and generate the resource indication message.

[0079] Further, the second time period is determined according to the location of the first device that sends the time period configuration information; the third time period is determined according to the location of the target device group that uses the released resources ( Figure 8 Schematic diagram for the third time period for the target device group).

[0080] Step 230: Receive a resource indication message, where the resource indication message is used to indicate the release of target resources or a request for additional PUSCH resources, and the target resources are configured PUSCH resources and are in a preset time period after the time point obtained by accumulating the characteristic time periods at the end time of the resource indication message.

[0081] There are at least two transmission opportunities within one cycle of the configured PUSCH resources.

[0082] Further, based on the value of the characteristic duration, it is determined whether to transmit the resource indication information. For example, when the value of the time period configuration information is the first value, the base station acquires the resource indication information; when the value of the time period configuration information is the second value, the base station does not detect the resource indication information. The second value can be preset by the base station and the terminal. In this way, the terminal device enables the processing of the resource indication information in response to the characteristic duration being the second value. For another example, by setting a threshold to determine the second value, the terminal device enables the processing of the resource indication information in response to the characteristic duration being greater than the set threshold.

[0083] Step 240: Transmit the information for scheduling the target resource.

[0084] As Figure 8 shown, the base station receives the resource indication information from UE1. The base station transmits the information for scheduling the target resource to any device among other terminal devices (or target device group) UE2 - 5.

[0085] Figure 9 The flowchart of the method of the present application for the terminal device is shown. The method described in any embodiment of the first aspect of the present application, when used for the terminal device, includes the following steps 310 - 330:

[0086] Step 310: Receive the recycling indication information, where the recycling indication information is used to indicate whether to transmit the resource indication information; based on the recycling indication information, the UE determines whether to transmit or stop transmitting the resource indication information.

[0087] Further, the recycling indication information is also used to determine the valid time for transmitting the resource indication information. The UE determines the timing for transmitting the resource indication information based on the recycling indication information.

[0088] Step 320: Receive the time period configuration information, where the characteristic duration indicated by the time period configuration information includes a first duration, a second duration, a third duration, or the sum of any of them; the first duration corresponds to the processing duration of the resource indication information, the second duration corresponds to the transmission duration of the resource indication information, and the third duration corresponds to the transmission duration of the information for scheduling the target resource.

[0089] Step 330: Transmit the resource indication information, where the resource indication information is used to indicate the release of the target resource or request additional PUSCH resources, and the target resource is the configured PUSCH resource and is in a preset time period after the time point obtained by accumulating the characteristic duration at the end time of the resource indication information.

[0090] The UE that transmits the resource indication information does not transmit a signal on the target resource.

[0091] Further, according to the value of the characteristic duration, it is determined whether to transmit the resource indication information. For example, when the value of the time period configuration information is the first value, the UE determines that the resource indication information needs to be sent; when the value of the time period configuration information is the second value, the UE determines that the resource indication information does not need to be sent.

[0092] The terminal-side device determines the target resource according to the distribution of the configured PUSCH resources and the occupancy of the packet service; according to the time period configuration information or the characteristic duration, it is determined whether the target resource is in a preset time period after the time point obtained by adding the characteristic duration to the end time of the resource indication information.

[0093] Combined Figures 5 to 9 , in the embodiments of the present application,

[0094] First, UE1 receives the configuration information of the gNB. The configuration information is used to configure the CG PUSCH resources for UE1. The CG PUSCH resources are periodic. Since the arrival time of the XR service data has a certain jitter on a periodic basis and the data volume of the XR service data also changes over time, the demand for PUSCH resources by UE1 is different within each CG PUSCH cycle. Releasing the resources unused by UE1 within the CG PUSCH cycle and having the gNB allocate the resources released by UE1 to the uplink of other UEs can improve the utilization efficiency of the uplink resources. Or, if the transmission resources within the CG PUSCH cycle cannot meet the data transmission requirements of UE1, UE1 can request additional PUSCH resources through the resource indication information to meet the uplink data transmission requirements and the efficiency of the uplink resources.

[0095] However, the configured PUSCH resources unused by UE1 do not always need to be recycled. In cases where the uplink resources are not tight, the number of UEs served by the gNB is not large, the radio resources or power required for the UE1 to send resource indication information on the usage of the configured PUSCH resources is large, or other UEs served by the gNB cannot use the configured PUSCH resources released by UE1, etc., the gNB may not recycle the configured PUSCH resources allocated to UE1. Therefore, after obtaining the configured PUSCH resources, UE1 can determine whether to send resource indication information. Optionally, UE1 determines whether to send resource indication information by obtaining the recycling indication information sent by the gNB. Optionally, the recycling indication information not only indicates whether to send resource indication information to UE1, but also indicates the valid time for whether to send the resource indication information. Alternatively, UE1 determines whether to send resource indication information based on the time period configuration information. In particular, within one cycle of the configured PUSCH resources, there are at least two transmission opportunities to meet the service requirements of the arrival time fluctuation and the size fluctuation of the service data volume. In this case, the configured PUSCH resources are more likely to be recycled due to non-use.

[0096] The resource indication information is used to indicate the target resources released by UE1. The target resources belong to the configured PUSCH resources. Optionally, the target resources are the resources of some transmission opportunities in the configured PUSCH resources. Alternatively, optionally, the target resources are some resources on some transmission opportunities in the configured PUSCH resources. To determine the target resources, the resource indication information indicates the position of the target resources within a preset time period. By configuring the time position of the preset time period, it can be ensured that if the configured PUSCH resources of UE1 are recycled by the gNB, they can be effectively allocated to other UEs. The time difference between the start time of the preset time period and the end transmission time of the resource indication information is not less than the characteristic duration. The characteristic duration is determined by the time period configuration information. The time period configuration information can be indicated by the gNB to UE1. The time period configuration information includes any one or any combination of the first duration T1, the second duration T 21 , and the third duration T 22 . T1 corresponds to the duration for the second device to process the resource indication information. T 21 corresponds to the information transmission duration for indicating the released resources. T 22 corresponds to the information transmission duration for scheduling the recycled resources. The gNB can determine T1 according to its own duration for processing the resource indication information. The gNB can determine T 21 according to the transmission delay of the resource indication information. The gNB can determine T 22 according to the transmission duration of the scheduling information for allocating the recycled resources to other UEs.

[0097] Figures 10(a) to (c) are schematic diagrams of the position and range in a preset time period. As shown in the figure, the resource indication information is used to indicate the release of target resources or the request for additional PUSCH resources. The target resources are represented by their time positions within the preset time period. The time difference between the start time of the preset time period and the end time of the resource indication information is not less than the characteristic duration. As shown in Figure 10(a), the start time of the preset time period is at the time unit boundary after the characteristic duration and the offset duration are counted from the end time of the resource indication information. The end time of the preset time period is the end time of the configured PUSCH cycle where the resource indication information is located. The offset duration is a preset value. As shown in Figure 10(b), the start time of the preset time period is at the time unit boundary after the characteristic duration is counted from the end time of the resource indication information. The end time of the preset time period is the end time of the configured PUSCH cycle where the resource indication information is located. As shown in Figure 10(c), the start time of the preset time period is at the time unit boundary after the characteristic duration is counted from the end time of the resource indication information. The end time of the preset time period is the end time of the configured PUSCH within the configured PUSCH cycle where the resource indication information is located.

[0098] Optionally, the start time of the preset time period is determined by the resource indication information and the characteristic duration. The preset time period and the resource indication information may also be in different configured PUSCH cycles.

[0099] The resource indication information indicates the position of the target resources within the preset time period, which can be represented by which times within the preset time period the time resources of the target resources occupy, or by which configured PUSCH resources within the preset time period the target resources are. The time position of the preset time period can be correspondingly determined through the time period configuration information, thereby ensuring that the configured PUSCH resources of UE1 can be recycled and used for other UEs to send data after being recycled.

[0100] Optionally, UE1 can also determine whether to send the resource indication information according to the value of the time period configuration information. When the value of the time period configuration information is the first value, it is determined that the resource indication information needs to be sent; when the value of the time period configuration information is the second value, it is determined that the resource indication information does not need to be sent.
