Description
Technical Field
The present disclosure relates to the field of wireless communications technologies, and in particular, to a method and an apparatus for configuring a data transmission resource.
Background
Physical Uplink Shared Channel (PUSCH) scheduling of a Configured Grant (CG) periodically allocates PUSCH resources to a particular terminal device (UE). The transmission of CG PUSCH configurations has two ways: one is CG PUSCH type 1, the resources for transmission grants are provided by RRC, and the UE stores the configuration and uses it as a grant configuration when there is an uplink data transmission. The other is CG PUSCH type 2, the RRC layer configures information such as the period of CG PUSCH, HARQ sequence number, etc., and then the physical downlink control channel PDCCH activates or deactivates the configuration. The PDCCH for activating or deactivating the CG PUSCH includes resources occupied by PUSCH in time and frequency, and a time position of the first CG PUSCH. The CG PUSCH resources may be used by the UE after the activation information is acquired.
The number of the PUSCHs occupied by the data packet is determined by the size of the data packet on the basis of the realization that the CG PUSCH comprises a plurality of PUSCH transmission opportunities in one period. For example, packet arrival for Extended Reality (XR) services is periodic, but the actual arrival time of the packet may experience jitter, resulting in its random arrival within a jitter time window. In addition, the packet size of XR varies with time. When configuring multiple CG PUSCH transmission opportunities per CG period, CG resources in the CG period may be over-allocated to avoid delays due to frequent requests for additional resources, since semi-statically configured CG resources do not match dynamic frame sizes well. To increase the resource utilization, it may be considered to dynamically recycle unused resources. Or CG resources in the CG period may not meet XR data transmission requirements in some cases, and additional PUSCH resources need to be allocated to the device.

Detailed Description
For the purposes, technical solutions and advantages of the present application, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of CG PUSCH type 2 scheduling in the prior art, where after a UE acquires a PDCCH for activating CG PUSCH, the UE periodically occupies CG PUSCH resources to send uplink information.
Fig. 2 is a schematic diagram of configuring multiple data transmission opportunities in one period of CG PUSCH. Packet arrival for an extended reality (XR) service is periodic, but the actual arrival time of the packet may experience jitter, resulting in random arrival within a jitter time window. FIG. 2 is an example in which a first jitter time window begins at time t 0 Wherein the XR data packet may be at t 0 To t 3 Arriving within this time window in between, with XR data packets in the figure at time t 1 Arriving. The next XR data packet arrives after time P, and the arrival time of the next XR data packet may be at t 4 To t 7 Any time within the jitter time window in between. For example, the next XR data packet in the figure is actually at time t 7 Arriving. In order to meet the characteristic of XR service arrival time jitter, a plurality of data transmission opportunities can be configured in one period P of CG PUSCH, and the requirement of timely sending after service packet arrival is met.
Fig. 3 is a schematic diagram of transmission opportunity data of a plurality of data transmission opportunities in one period of CG PUSCH. The data packet size of XR varies with time. Taking the AR/VR 30Mbps as an example, the maximum packet size is 93750 bytes and the minimum packet size is 31250 bytes. The number of the PUSCHs occupied by the data packet is determined by the size of the data packet on the basis of the realization that the CG PUSCH comprises a plurality of PUSCH transmission opportunities in one period. As shown, in the first period of CG PUSCH, XR data packets occupy 3 PUSCHs for transmission of TB1, TB2 and TB3, respectively. In the next CG PUSCH period, the XR data packet occupies 1 PUSCH transmission TB4.
Fig. 4 is a timing usage indication of a plurality of data transmission timing resources within one period of CG PUSCH. In this example, there are four transmission opportunities within one period of CG PUSCH resources configured for the UE. Based on the actual resources occupied by the XR data in each period, the UE may send its own "resource usage indication" of the usage of these resources to the gNB. For unused resources, the gNB can be allocated to other UEs, so that the use efficiency of uplink resources is improved.
Fig. 5 is a schematic diagram of CG PUSCH recovery resource reallocation. As shown, the resources are used in one period of CG PUSCH allocated to UE1 by the gNB. Slot# (n+3) to Slot# (n+15) are PUSCH transmission opportunities in the period, and each PUSCH transmission opportunity has PUSCH resources allocated to UE 1. The actual XR data of UE1 occupies the resources of slot# (n+3) to slot# (n+5) in this period. If the "resource usage indication" is transmitted at slot# (n+3), CG PUSCH resources indicating slot# (n+6) through slot# (n+15) may be reclaimed. The gNB reallocates the reclaimed resources to other UEs, which need to acquire scheduling indications before using the corresponding resources. However, the gcb acquires CG resource release information of UE1 at slot# (n+3). UE2 is far from gNB, which needs to reach UE2 at slot# (n+13) even if a scheduling indication is sent to UE2 at slot# (n+3). Therefore, only slot# (n+14) and slot# (n+15) in CG resources released by UE1 can be reused by UE2. For UE3 farther from the gNB, none of the CG resources released by UE1 can be notified of the gNB and allocated to UE3 before it can be occupied.
Consider the time from acquisition of the "resource usage indication" sent by the UE from the gNB to the time required by the gNB to schedule CG PUSCH resources not used by the UE to other UEs, the time period including any combination of:
first kind: the UE determines and processes the time of the "resource usage indication". The period length depends on the processing speed and scheduling speed of the UE.
Second kind: the gNB parses the "resource usage indication" and the processing time of the gNB to allocate the "reclaimed resources" to other UEs, the time period length being dependent on the processing speed and scheduling speed of the gNB.
Third kind: the "resource usage indicates" the air propagation delay of the information. When the communication distance is short, the air propagation delay of the resource use indication is small and can be ignored. In a non-terrestrial communication system such as ground-air communication or satellite communication, the propagation delay of information is long, an unused CG PUSCH resource indication of a UE needs to reach and be known by the gNB after a period of time, and then the unused CG PUSCH resource is allocated to other UEs by the gNB. The propagation delay in air of the allocation information also needs to be subject to propagation delay in air.
It should be noted that any combination includes one case.
In the example of fig. 5, if CG resources released by UE1 cannot be reallocated to other UEs, the UE1 sends a "resource usage indication" that does not serve the purpose of improving uplink resource usage efficiency, but instead makes UE1 send invalid information, reducing feedback resource efficiency and power efficiency of UE 1.
Fig. 6 is a flow chart of an embodiment of the method of the present application. The application proposes a method for configuring data transmission resources, comprising the following steps 110 to 130:
step 110, determining time period configuration information, wherein the characteristic time period indicated by the time period configuration information is a first time period, a second time period, a third time period or the sum of any of the first time period, the second time period and the third time period; the first time length corresponds to the processing time length of the resource indication information, the second time length corresponds to the transmission time length of the resource indication information, and the third time length corresponds to the information transmission time length of the scheduling target resource.
The processing duration of the resource indication information corresponding to the first duration refers to 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, and preferably, the processing duration of the resource indication information is not higher than the first duration.
The second time length corresponds to a transmission time length of the resource indication information, which means that the second time length is a characteristic value preset according to the transmission time length of the resource indication information and is equivalent to the transmission time length of the resource indication information, and preferably, the transmission time length of the resource indication is not higher than the second time length.
The third time length corresponds to the information transmission time length of the scheduling target resource, which means that the third time length is a characteristic value preset according to the information transmission time length of the scheduling target resource, and is equivalent to the information transmission time length of the scheduling target resource, and preferably, the information transmission time length of the scheduling target resource is not higher than the third time length.
Whether UE1 sends a "resource usage indication" is configured by the gNB. The gNB determines configuration information for the UE1 according to the resources and power used by the UE for sending the resource use indication and the reassignment efficiency of the recovery resources. For example, the gNB may configure the UE1 not to send the "resource usage indication" if it is determined that the unused resources of the reclaimed UE1 are not necessarily allocated to other UEs, or that the reuse of reclaimed resources cannot make up for the cost of the UE1 sending the "resource usage indication".
Preferably, it is determined whether to transmit the resource indication information according to the value of the characteristic duration.
Preferably, the effective time range for transmitting the resource indication information is determined according to the recovery indication information.
The one period of the configured PUSCH resource includes at least 2 PUSCH transmission opportunities.
The "resource usage indication" sent by UE1 is used to determine which CG PUSCH resources allocated to UE1 are released. Alternatively, the "resource usage indication" sent by UE1 is used to determine additional PUSCH resources beyond the CG PUSCH resources requested.
For example, the time difference between the time position of the "resource usage indication" and the time position of the recovered CG PUSCH resource is at least not less than T 1 And T 2 And (2) sum:
T 1 : the time that the gNB processes the "resource usage indication", optionally, further includes the processing time that the gNB allocates "reclaimed resources" to other UEs.
T 2 : time offset. Air propagation delay T indicated to UE by gNB including "resource usage indication" information 21 And scheduling indicated air propagation delay T 22 。T 21 Reflecting the time of gNB obtaining "resource usage indication", T 22 Reflecting the time when the gNB allocated the reclaimed resources to other UEs. gNB indicates T to UE1 2 ＝T 21 +T 22 Alternatively, the gNB indicates T to UE1 respectively 21 And T 22 . As shown in fig. 8, T 21 Corresponding to a second time length, T 22 And corresponding to the third duration, reflecting the time required by the gNB to allocate the recovered resources to any one device in the target device group.
In particular, T 2 、T 21 Or T 22 If any one of the items is a preset value, it is not necessary to send "resource usage instruction" to the UE 1.
Again, the "resource usage indication" indicates CG PUSCH resources released within the preconfigured period after the base time offset.
It should be noted that, the above steps are used for a network entity of a wireless communication system, and include a terminal side device, a network side device or other intermediate devices; the above steps may also be used for providing information processing service means for the network entity device; the above steps may also be applied to any apparatus, system, subsystem, circuit, chip or software entity that provides information receiving, transmitting, identifying, and processing for a terminal-side device or a network-side device.
Fig. 7 is a flowchart of an embodiment of a method for network side equipment according to the present application. The method according to any one of the embodiments of the first aspect of the present application, for a network side device, includes the following steps 210 to 240:
The reclamation instruction information is used for indicating whether the terminal side equipment UE transmits the resource instruction information.
Step 220, sending time period configuration information, wherein the characteristic time period indicated by the time period configuration information comprises a first time period, a second time period, a third time period or the sum of any of the first time period, the second time period and the third time period; the first time length corresponds to the processing time length of the resource indication information, the second time length corresponds to the transmission time length of the resource indication information, and the third time length corresponds to the information transmission time length of the scheduling target resource.
The processing duration of the resource indication information comprises the duration of the network side for identifying and determining the resource indication information, and/or the duration of the terminal side for determining and generating the resource indication information.
Further, determining the second duration according to the position of the first device sending the time period configuration information; the third time period is determined according to the location of the target device group using the released resource (fig. 8 is a schematic diagram of the third time period for the target device group).
There are at least two transmission opportunities within one period of the configured PUSCH resource.
Further, according to the value of the characteristic duration, whether the resource indication information is transmitted is determined. For example, when the value of the period configuration information is a first value, the base station acquires the resource indication information; and 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 may be preset by the base station and the terminal, so that the terminal side device responds to the characteristic duration as the second value to enable the processing of the resource indication information. For another example, by setting a threshold to determine the second value, the terminal-side device disables the resource indication information processing in response to the feature time period being longer than the set threshold.
And 240, transmitting information for scheduling the target resource.
As shown in fig. 8, the base station receives the resource indication information from the UE 1. The base station transmits information for scheduling the target resource to any one of the other terminal devices (or target device group) UE2 to 5.
Fig. 9 is a flowchart of an embodiment of a method for a terminal side device according to the present application. The method according to any one embodiment of the first aspect of the present application, for a terminal side device, includes the following steps 310 to 330:
step 310, receiving recycling indication information, wherein the recycling indication information is used for indicating whether to transmit resource indication information; and according to the recycling indication information, the UE determines to send or stop sending the resource indication information.
Further, the recovery indication information is further used for determining effective time for sending the resource indication information. And the UE determines the time for transmitting the resource indication information according to the recovery indication information.
Step 320, receiving period configuration information, wherein the characteristic duration indicated by the period configuration information comprises a first duration, a second duration, a third duration or a sum of any of the first duration, the second duration and the third duration; the first time length corresponds to the processing time length of the resource indication information, the second time length corresponds to the transmission time length of the resource indication information, and the third time length corresponds to the information transmission time length of the scheduling target resource.
And the UE transmitting the resource indication information does not transmit signals on the target resource.
Further, according to the value of the characteristic duration, whether the resource indication information is transmitted is determined. For example, when the value of the period configuration information is a first value, the UE determines that the resource indication information needs to be transmitted; and 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.
The terminal side equipment determines the target resource according to the distribution of the configured PUSCH resource and the occupation condition of the grouping service; and determining whether the target resource is in a preset period after the time point obtained by accumulating the characteristic duration in the ending time of the resource indication information according to the period configuration information or the characteristic duration.
In connection with fig. 5-9, in an embodiment of the present application,
first, UE1 receives configuration information of the gNB. The configuration information is used to configure CG PUSCH resources for UE 1. CG PUSCH resources are periodic. Because the time for reaching XR service data has a certain jitter on a periodic basis, the data volume of the XR service data also changes with time, so that the requirements of UE1 on PUSCH resources in each CG PUSCH period are different, unused resources of UE1 in the CG PUSCH period are released, and the resources released by UE1 are distributed to the uplink of other UEs by gNB, so that the utilization efficiency of the uplink resources can be improved. Or if the transmission resource in the CG PUSCH period cannot meet the UE1 data transmission requirement, the UE1 may request additional PUSCH resources through the resource indication information, so as to meet the uplink data transmission requirement and the efficiency of the uplink resources.
However, the configured PUSCH resources not used by UE1 do not always need to be recycled, and in the case where uplink resources are not tight, the number of UEs served by the gNB is not large, radio resources or power required for UE1 to transmit resource indication information of the configured PUSCH resource usage situation is large, or other UEs served by the gNB cannot use the configured PUSCH released by UE1, the gNB may not recycle the configured PUSCH resources allocated to UE 1. Thus, UE1 may determine whether it is necessary to transmit the resource indication information after acquiring the configuration PUSCH resource. Optionally, the UE1 determines whether the resource indication information needs to be sent by acquiring the reclamation indication information sent by the gNB. Alternatively, the reclamation instruction information indicates not only whether to send the resource instruction information to the UE1, but also the valid time of whether to send the resource instruction information. Alternatively, the UE1 determines whether the transmission of the resource indication information is required through the period configuration information. In particular, at least two transmission opportunities exist in one period of configuring the PUSCH resource to meet the service requirements of service arrival time fluctuation and service data volume fluctuation. In this case, there is a greater possibility that the PUSCH resources are recovered due to non-use in the configuration.
The resource indication information is used to indicate the target resources released by the UE1. The target resource belongs to the configuration PUSCH resource. Optionally, the target resource is a resource for configuring a part of transmission occasions in the PUSCH resource. Or, alternatively, the target resource is a part of resources on a part of transmission occasions in the configuration PUSCH resource. To determine the target resource, the resource indication information indicates a location of the target resource within a preset period. By configuring the time position of the preset period, it can be ensured that the configured PUSCH resources of UE1 can be effectively allocated to other UEs if recovered by the gNB. The time difference between the starting time of the preset period and the ending sending time of the resource indication information is not smaller than the characteristic duration. The characteristic duration is determined by the period configuration information. The period configuration information may be indicated to UE1 by the gNB. The time period configuration information includes a first time period T 1 A second time length T 21 A third time length T 22 Any or a combination of any more of the above. T (T) 1 And corresponding to the duration of processing the resource indication information by the second device. T (T) 21 And correspondingly indicating the information transmission time length of the released resources. T (T) 22 And the information transmission time length of the corresponding scheduling recovery resource. The gNB can determine T according to the duration of processing the resource indication information 1 . The gNB can determine T according to the transmission delay of the resource indication information 21 . The gNB may determine T based on a transmission duration of scheduling information for allocating reclaimed resources to other UEs 22 。
Fig. 10 (a) to (c) are schematic diagrams of positions and ranges of the preset period. As shown, the resource indication information is used to indicate release of target resources or request of additional PUSCH resources. The target resource is represented by its time position within a preset period. The time difference between the starting time of the preset period and the ending time of the resource indication information is not smaller than the characteristic duration. As shown in fig. 10 (a), the start time of the preset period is located at a time unit boundary after the feature duration and the offset duration from the end time of the resource indication information. The end time of the preset period is the end time of the configured PUSCH period where the resource indication information is located. Wherein the bias duration is a preset value. Fig. 10 (b) shows a time unit boundary where the start time of the preset period is located after the end time of the resource indication information by the characteristic duration. The end time of the preset period is the end time of the configured PUSCH period where the resource indication information is located. Fig. 10 (c) shows a time unit boundary where the start time of the preset period is located after the end time of the resource indication information by the characteristic duration. The ending time of the preset period is the configured PUSCH ending time in the configured PUSCH period where the resource indication information is located.
Optionally, the starting time of the preset period is determined by the resource indication information and the characteristic duration. The preset period and the resource indication information may also be located in different periods of configuring PUSCH.
The resource indication information indicates the position of the target resource in the preset time period, which time of the preset time period is occupied by the time resource of the target resource, and which configuration PUSCH resource of the target resource in the preset time period. The time position of the preset time period can be correspondingly determined through the time period configuration information, so that the fact that the configuration PUSCH resource of the UE1 is recovered and then can be used for other UEs to send data is ensured.
Optionally, the UE1 may further determine whether to send the resource indication information according to the value of the period configuration information. When the value of the time period configuration information is a first value, determining that the resource indication information needs to be sent; and when the value of the time period configuration information is the second value, determining that the resource indication information does not need to be sent.
Fig. 11 is a schematic diagram of an embodiment of a network side device.
The embodiment of the application also provides a network side device, which is used for realizing the configuration method of the data transmission resource according to any one embodiment of the application, wherein at least one module in the network side device is used for at least one function of: determining the characteristic duration; determining the time period configuration information; transmitting the time period configuration information; determining whether the terminal side transmits the resource indication information; receiving the resource indication information; determining the resource indication information; determining the target resource; and sending information for scheduling the target resource.
