Description

Data resource configuration method and equipment

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 resource.

Background

After acquiring the CG PUSCH configuration information, the data transmitting device uses resources of CG PUSCH configuration to transmit data according to the data to be transmitted cached by the data transmitting device. And the data receiver acquires information sent by the data sending end by blindly detecting CG PUSCH resources configured for data sending.

In the case that there are various data transmission modes in which the data transmission device actually occupies CG PUSCH resources, the complexity of blind detection of data transmission by the data reception device may be great. Particularly, for XR service transmission, if multiple data transmission occasions can be configured in one period P of the CG PUSCH, and if any of the actual data transmission start transmission occasions are uncertain, whether the data transmission is repeated, and the number of transmission occasions occupied by the data transmission are uncertain, complex blind detection may affect the normal operation of the data receiving end. For example, there is X in one period of CG PUSCH configuration ₁ In the case of multiple transmission opportunities, the actual data transmission in the period may occupy X therein ₂ (X ₂ ≤X ₁ ) Resources on each transmission occasion. And, wherein X ₃ (X ₃ ≤X ₂ ) The actual data at each transmission timing is the same, and is the data to be repeatedly transmitted. Alternatively, X ₄ (X ₄ ≤X ₂ ) The actual data on one transmission occasion may constitute the data of one transport block with the actual data on the other transmission occasion or occasions. In different periods of CG PUSCH configuration, the actual data transmission conditions may be different, X ₂ 、X ₃ 、X ₄ May be different. Thus, the complexity and the efficiency of the blind detection of the data by the data receiving end are high.

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 application scenario of the present application is for data information between a network side device (e.g., a gNB) and a terminal side device (e.g., a UE).

Taking a device for transmitting data as a UE, a device for receiving data as a gNB as an example, and in the application and the data scheme, the UE and the gNB preset data transmission mode combinations actually occupying CG PUSCH resources, where the data transmission mode combinations include at least one transmission mode, and each transmission mode is any one of transmission time of actual data start, number of transmission time occupied by actual data transmission, number of repetitions of actual data transmission, number of transmission time combinations corresponding to actual data transmission, and correspondence between type of actual data transmission and transmission time. And the gNB indicates the data transmission mode combination in the configuration information of the CG PUSCH, or the UE sends indication information to carry the data transmission mode combination. And the gNB determines reuse resources in the CG PUSCH resources according to the data detection result and the data transmission mode combination and distributes the reuse resources to other UE.

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 flow chart of an embodiment of the method of the present application.

The application proposes a data resource configuration method, which comprises the following steps 110 to 130:

step 110, determining a first resource, where the first resource is an uplink data transmission resource configured according to a set period, and any period includes N available data transmission opportunities.

For example, the period of the first resource is P, and the Q-th period time of the first resource contains N.gtoreq.2 transmission opportunities.

The first resource is CG PUSCH resource. CG PUSCH scheduling allocates PUSCH resources periodically to a particular UE. There are two kinds of CG PUSCH configured resources: 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 first resource satisfies periodicity. Taking the period as P as an example, in order to meet the transmission requirement of service data arrival time jitter and/or service data volume fluctuation, N is more than or equal to 2 transmission opportunities in one period time of the first resource. Since the gNB needs to detect all the possibilities of data transmission on CG PUSCH resources under any of uncertainty of the transmission timing of the actual data transmission in one period P of CG PUSCH, uncertainty of whether the data transmission is repeated transmission, and uncertainty of the number of transmission timings occupied by the data transmission, the complexity of detection is great, and the complexity of gNB and the efficiency of detection are affected.

Step 120, determining a target transmission mode, where the target transmission mode is one of set transmission modes, and each set transmission mode includes an actual data transmission opportunity distribution in any period.

For example, the gNB and/or the UE determine a combination of data transmission manners, where the combination of data transmission manners includes at least one transmission manner, where the transmission manner includes a start transmission opportunity of actual data transmission on the first resource, a number of transmission opportunities occupied by the actual data transmission, a number of repetitions of the actual data transmission, a number of transmission opportunity combinations corresponding to the actual data transmission, and an actual data transmission opportunity distribution described by any parameter in an actual data transmission format.

According to the embodiment, the complexity of detecting the data on the CG PUSCH and the use efficiency of the CG PUSCH resources by the gNB can be controlled by limiting the use mode of the resources on each transmission occasion when the actual data is transmitted on the CG PUSCH resources. Specifically, as shown in fig. 10 to 14, data transmission schemes A1 to A4, B1 to B4, C1 to C4, D1 to D4, and E1 to E4 are exemplified (see below for details).

And 130, determining M transmission occasions among N transmission occasions in any period as second resources for transmitting target data, wherein the M transmission occasions meet the target transmission mode.

After one of the data transmission mode combinations is determined to be a target transmission mode, determining a second resource according to the target transmission mode, wherein the second resource is M transmission occasions of the first resource in the Q-th period time, and M is less than N; the second resource is used for transmitting target data.

One of the data transmission mode combinations is determined as a target transmission mode, and a second resource is determined according to the target transmission mode, wherein the second resource is M transmission occasions of the first resource in the Q-th period time, and M is less than N. The second resource is used for transmitting the target data.

For example, at the UE side, a second resource is determined according to the target transmission mode, and the target data is sent on the second resource. The resources on N more than or equal to 2 transmission occasions in the Q-th period time of the CG PUSCH are configured for meeting the arrival time jitter of service data and the floating change of the packet size of the service data, and the data which occupies the CG PUSCH resources in the Q-th period time actually occupy M transmission occasions and M is less than N. In the way that the gNB predicts that the UE occupies the transmission time when actually transmitting data on the CG PUSCH resource, the gNB does not need to always detect the N transmission time, and the detection efficiency of the gNB can be improved.

Preferably, the UE determines the combination of the data transmission modes and/or the target transmission mode, and sends the relevant information to the gNB, so as to achieve the purpose of presetting the information. For some services, the UE may predict future data parameters better than the gNB, the UE may combine as a data transmission scheme, and/or the target transmission scheme determination may obtain more efficient data resource usage efficiency and the efficiency of gNB data detection.

For another example, on the gNB side, a target transmission mode is selected according to the determined second resource, and a notification is sent to the terminal side device. Therefore, the gNB may also determine the above data transmission mode combination and/or the target transmission mode, and send relevant indication information to the UE.

Preferably, after acquiring the information of the data transmission mode combination of the UE and/or acquiring the information carrying the target transmission mode, the gNB may allocate the third resource on the CG PUSCH to other UEs. Taking the UE currently configured with CG PUSCH resources as a first terminal device, the first device determines to use a second resource in the first resource to send data according to information of data transmission mode combination and/or information of a target transmission mode, and the gNB may allocate a third resource to the second terminal device. The third resource belongs to the first resource and does not belong to the second resource. Therefore, the use efficiency of CG PUSCH resources is improved, and the network capacity can be further improved.

It should be noted that the above steps are used for a network entity of the 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 a service device providing information processing 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. 2 is a schematic diagram of CG PUSCH type 2. In step 110, for example, the first resource is CG PUSCH resource. CG PUSCH scheduling allocates PUSCH resources periodically to a particular UE. There are two kinds of CG PUSCH configured resources: 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 configuration information of CG PUSCH type 1 includes the time frequency resource location of PUSCH. 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. After the UE acquires the activation information, all CG PUSCH resources may be determined according to the time-frequency location of the first CG PUSCH and the period of the CG PUSCH configuration. Fig. 2 is a CG PUSCH type 2, and after the ue acquires the PDCCH for activating the CG PUSCH, the ue periodically occupies the CG PUSCH resource to send uplink information.

The configuration information includes parameters required for uplink transmission, such as a period (periodicity), a HARQ process number (nrofHARQ-Processes), a power control, a repetition number (repK), and a redundancy version (repK-RV), regardless of the CG PUSCH type 1 or the CG PUSCH type 2.

Fig. 3 is a schematic diagram of CG PUSCH type repeated transmissions.

CG PUSCH transmissions support repeated transmissions to improve reliability, the number of which is configured by the parameter repK. When repK >1, the UE should repeatedly transmit the same TB K times on K transmission occasions, where K transmission occasions are located in K consecutive slots within one period. A schematic diagram of repk=4 is shown in fig. 3.

Fig. 4 is a schematic diagram of configuring a plurality of data transmission opportunities within one period of the CG PUSCH. For example, XR traffic related CG PUSCH configuration. Packet arrival for Extended Reality (XR) services is periodic, but the actual arrival time of the packet may experience jitter, resulting in random arrival within the jitter time window. In the example of fig. 4, the first jitter time window starts at time t0, where XR data packets may arrive within this time window between t0 and t3, where XR data packets arrive at time t 1. The next XR data packet arrives after time P, and the arrival time of the next XR data packet may arrive at any time within the jitter time window between t4 and t 7. The next XR data packet in the figure arrives at time t 7. In order to meet the characteristic of XR service arrival time jitter, a plurality of data transmission opportunities, namely first resources, can be configured in one period P of CG PUSCH, and the requirement of timely sending after service packets arrive is met.

Fig. 5 is a schematic diagram of actually transmitting data at a plurality of data transmission occasions within one period of the 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 size of PUSCH resources occupied by a data packet is determined by the size of the data packet based on the implementation that the CG PUSCH includes a plurality of PUSCH transmission opportunities within one period. As shown in the following diagram, in the first period of CG PUSCH, XR data packets occupy 3 PUSCH resources. In the period of the next CG PUSCH, XR data packets occupy 1 PUSCH resource.

Fig. 9 is a flowchart of another embodiment of the method for a terminal-side device according to the present application.

The method according to any one of the embodiments of the first aspect of the present application, for a terminal-side device, includes the following steps 321 to 323. In this embodiment, a target transmission mode is determined according to the received indication information, and target data is transmitted according to the second resource that satisfies the target transmission mode.

And/or receiving third indication information, where the third indication information is used to indicate a target transmission mode, and the target transmission mode is one of the set transmission modes.

And determining transmission modes of multiple settings according to the second indication information, or wherein the terminal equipment comprises prestored information of the transmission modes of the multiple settings. The terminal equipment selects a target transmission mode from a plurality of set transmission modes, or the terminal equipment determines the target transmission mode according to the third indication information.

Step 323, determining M transmission opportunities among N transmission opportunities in the any period as a second resource for transmitting target data, where the M transmission opportunities satisfy a target transmission mode, and the target transmission mode is one of the set transmission modes.

And the terminal side equipment determines M transmission occasions of the second resource (or the third resource) in N transmission occasions of the first resource according to the target transmission mode.

For example, the transmission mode includes an actual data start transmission opportunity and the number of transmission opportunities occupied by actual data transmission at each start transmission opportunity.

For example, the transmission mode includes an actual data start transmission opportunity and a repetition number of actual data transmission at each start transmission opportunity.

For example, the transmission mode includes an actual data start transmission opportunity and a joint number of start transmission opportunities.

For example, the transmission mode includes an actual data start transmission time and an actual data transmission format.

The following illustrates different cases of data transmission modes:

fig. 10 is a schematic diagram of a distribution of initial transmission occasions of actual data transmission on CG PUSCH configuration resources. The data transmission mode actually occupying the CG PUSCH resources is the transmission opportunity at which the actual data transmission starts, or the transmission opportunity at which the actual data transmission starts and the number of occupied transmission opportunities.

The data transmission mode actually occupying CG PUSCH resources refers to the transmission opportunity where the actual data transmission start time is located. The UE and the gNB preset transmission time at which the actual data transmission starting moment is located. For example, as shown in fig. 10, the data transmission schemes A1, A2, A3, A4 refer to the case where the transmission timing j at which the actual data transmission start time is within the transmission period of the CG PUSCH satisfies mod (j, m) =0, (m=1, 2,3, 4), respectively. The preset actual data transmission start time is not limited to the periodicity, and may be any one as long as both the gNB and the UE preset actual data transmission start time.

By limiting the transmission time at which the actual data transmission starts, the device can only start from the preset transmission time when transmitting the actual data on the CG PUSCH resource, so that the complexity of the gcb for detecting the actual data transmission on the CG PUSCH resource can be controlled. If no data is transmitted at the transmission opportunity at the moment of the actual data transmission start, the CG PUSCH resource is not occupied until the transmission opportunity at the moment of the next actual data transmission start. The gNB may not detect the data on the CG PUSCH configuration resource before the transmission timing at the next actual data transmission start time after detecting the actual data at the transmission timing at the actual data transmission start time and determining that the data transmission is finished. Further, if the UE is limited to have only one data transmission in one period of CG PUSCH configuration resource, the gNB determines that other transmission occasions in the period no longer detect data after the end of the data transmission. The data transmission scheme combination includes a data transmission scheme A3 as an example. The transmission mode A3 refers to that the transmission time at the beginning of the actual data transmission in a period of one CG PUSCH resource is in time slots 1, 5, 9, 13, 17, etc., and if the gcb does not detect the actual data transmission in time slot 1, the data of the UE may not be detected in time slots 2 to 4. If the gNB detects the actual data transmission in the time slot 1 and determines that the data transmission is finished in the time slot 3, the data of the UE may not be detected in the time slot 4. If the gNB detects the actual data transmission in the time slot 1 and determines that the data transmission is finished in the time slot 7, the data of the UE may not be detected in the time slot 8. Accordingly, when the gcb processing capability is used loosely, the data transmission scheme A1 for the UE to actually occupy CG PUSCH resources can be configured, and when the gcb processing capability is used loosely, the data transmission scheme A4 for the UE to actually occupy CG PUSCH resources can be configured. It should be noted that, limiting the transmission timing at the start time of the actual data transmission may also affect the real-time performance of the actual data transmission. And determining a plurality of set transmission modes and target transmission modes according to the delay requirement of actual data to be transmitted, the size of a data packet, the processing capacity of the gNB and the like whether the gNB or the UE is arranged. For example, in the case that the gNB processing capability can both satisfy the data transmission modes A3 and A4 actually occupying the CG PUSCH resource, if the data transmission mode A3 can satisfy the data transmission delay requirement and the data transmission mode A4 cannot satisfy the data transmission delay requirement, the UE is configured to use the data transmission mode A3 actually occupying the CG PUSCH resource.

Fig. 11 is a schematic diagram of actually sending data at multiple data transmission occasions on a CG PUSCH configuration resource.

Further preferably, the data transmission manner actually occupying CG PUSCH resources refers to the transmission opportunity at which the actual data transmission start time is located and the number of occupied transmission opportunities. The UE and the gNB preset the transmission time at which the actual data transmission starts, and also preset the number of transmission times occupied by the actual data transmission. For example, as shown in fig. 11, the data transmission modes B1, B2, B3, and B4 refer to the case where the number of transmission occasions occupied by the preset actual data transmission is 1, 2, 3, and 4, respectively, on the basis of the transmission occasion at which the preset actual data transmission start time is located. The complexity of detecting the actual data transmission on the CG PUSCH resource by the gNB can be controlled by presetting the transmission time at the actual data transmission starting time and the number of occupied transmission time by the UE and the gNB. And detecting data according to the transmission time at which the preset actual data transmission starting moment is positioned by the gNB, and detecting data according to the number of preset occupied transmission time after detecting that the actual data transmission is finished. The data on the CG PUSCH configuration resource may not be detected until the transmission occasion at which the next actual data transmission start time is located. For example, the UE and the gNB preset a data transmission mode that actually occupies CG PUSCH resources to be B2. The transmission mode B2 refers to that the transmission time at which the actual data transmission starts in a period of one CG PUSCH resource is in time slots 2, 7, 10, 15, etc., and the actual data sent at the transmission time at which each start starts occupies 2 transmission times. If the gNB detects an actual data transmission in slot 2, then no data for the UE may be detected in slots 4 through 6 after detecting an actual data transmission in slot 3.

Fig. 12 is a diagram of actually repeating data transmission at multiple data transmission occasions on CG PUSCH configuration resources. The transmission time at which the actual data transmission starts and the number of repetitions corresponding to the transmission time at which each start is located.

The repeated transmission can improve the reliability of the actual data transmission on the CG PUSCH resources. The number of repetitions of actual data transmitted on different transmission occasions on the CG PUSCH resources is different due to different reliability requirements for the transmission of the plurality of actual data and or due to different channel transmission conditions on different transmission occasions on the CG PUSCH resources. If the gNB does not know which transmission occasions the data on is repeated and which transmission occasions the data on is single-transmitted, the gNB cannot combine the detected data to obtain a combining gain when detecting the demodulated data. Alternatively, the gNB needs to attempt various data retransmission possibilities to demodulate the data, and the detection complexity is very high. The complexity of detecting the actual data transmission on the CG PUSCH resource by the gNB can be controlled by presetting the transmission time at which the actual data transmission starts and the repetition times corresponding to the transmission time at which the actual data transmission starts. As shown in fig. 7, the data transmission modes C1, C2, C3, and C4 refer to the case where the number of preset actual data repetition transmissions is 2, 3, 4, and 5 based on the transmission timing at which the preset actual data transmission start time is located, respectively. The transmission time at which the actual data transmission starting moment is located and the repetition number used by the actual data transmission are preset between the UE and the gNB, and the gNB can combine and receive the repeated data when detecting the actual data on the CG PUSCH resource, so that the reliability of the data transmission is improved. Similar to the step (1), the complexity of detecting the actual data transmission on the CG PUSCH resources by the gNB can be controlled by presetting the transmission time at which the actual data transmission starts and the repetition times corresponding to the transmission time at which the actual data transmission starts by the UE and the gNB. And the gNB sequentially determines the transmission time and detects the data according to the repetition times corresponding to the transmission time at each starting moment according to the transmission time detection data at the preset actual data transmission starting moment. The data on the CG PUSCH configuration resource may not be detected until the transmission occasion at which the next actual data transmission start time is located.

Also, the preset actual data transmission start time is not limited to the periodicity, and may be any one as long as both the gNB and the UE preset actual data transmission start time.

Fig. 13 is a diagram illustrating actual joint transmission of data at multiple data transmission occasions on CG PUSCH configuration resources. The transmission time at the initial time corresponding to the actual data transmission is combined with the transmission time.

The size of the data packet of the service changes with time, and the large data packet is several times of the small data packet, so that more resources on CG PUSCH configuration transmission opportunity are occupied. For large data packets, they may be transmitted in multiple data blocks, or may be transmitted in one large transport block. After the large transport block is encoded and modulated, resources on multiple transmission occasions are needed to carry the large transport block. The number of the plurality of transmission occasions is referred to as a transmission occasion joint number. As shown in fig. 8, the data transmission modes B1, B2, B3, and B4 refer to the cases where the number of transmission opportunity combinations corresponding to the actual data transmission is 2, 3, 4, and 5, respectively.

If there is no preset transmission opportunity combination number between the gNB and the UE, the gNB cannot correctly demodulate the data transmitted by the UE on the CG PUSCH. The transmission requirements of the gNB on the CG PUSCH resource can be changed by presetting the transmission time at the actual data transmission starting time and the transmission time combination quantity between the gNB and the UE.

Fig. 14 is a distribution of actual data transmission formats of a plurality of data transmission occasions on CG PUSCH configuration resources, and shows a correspondence between the actual data transmission formats and the transmission occasions.

The type of the actual data transmission is matched with the service requirement of the service, for example, the arrival time of the service meets the preset distribution, and correspondingly, the transmission time occupied by the actual data transmission in the transmission period of the CG PUSCH corresponds to the preset distribution. As shown in the data transmission scheme E1 of fig. 9, the relative positional relationship between transmission timings at which actual data is transmitted in the transmission period of the CG PUSCH is the same as the relative positional relationship between

slots

2, 4, 5, 6, 9, 10, 13, 14, 15. The data transmission scheme E2 has the same relative positional relationship among the transmission timings of the CG PUSCH in the transmission cycle as the relative positional relationship among the

slots

4, 6, 7, 9, 10, 13, 14, 15, and 16. After the gNB detects the initial transmission of the actual data transmission, the data can be detected at the transmission time in the period according to the preset data transmission mode with the UE. In this way, the efficiency of gNB detection data can be improved.

The data transmission mode combination comprises at least one transmission mode. Any one of the at least one transmission modes may be any one of a start transmission opportunity of actual data transmission on the first resource, a number of transmission opportunities occupied by the actual data transmission, a number of repetitions of the actual data transmission, a number of transmission opportunity combinations corresponding to the actual data transmission, and an actual data transmission format. For example, the data transmission scheme combination includes data transmission schemes B2, C2, D2, and E2. The set transmission mode can also be any combination of the initial transmission time of the actual data transmission, the transmission time number occupied by the actual data transmission, the repetition number of the actual data transmission and the transmission time combination number corresponding to the actual data transmission. For example, the data transmission scheme combination includes data transmission schemes Q1, Q2, Q3, and Q4. The transmission mode Q1 sets a start transmission opportunity of actual data transmission, and the number of transmission opportunities occupied by actual data transmission on a part of the start transmission opportunity, and the number of repetitions of actual data transmission on a part of the start transmission opportunity.

In any one embodiment of the present application, the transmission frequency of the first indication information is lower than the transmission frequency of the second indication information and the third indication information. The first indication information is used for configuring CG PUSCH resources, has the characteristic of one-time configuration and multiple-time use, and can meet the data transmission requirement of relatively stable period and traffic. If the actual data corresponding to the service is quasi-periodic, the service volume also fluctuates with time to a certain extent, and the reliability requirement of data transmission is higher. Such as XR traffic. If the transmission resources of the service are allocated using dynamic scheduling, the dynamic scheduling indication message may be heavily burdened, and the distribution characteristics of the service data do not play a role in the resource allocation process. If the existing CG PUSCH resource allocation method is used, the gNB faces the problems of high complexity in detecting CG PUSCH resources and low CG PUSCH resource usage efficiency. With the scheme of this embodiment, the first indication information is used to determine the first resource, that is, the uplink data transmission resource configured according to the set period, where any period includes N available data transmission opportunities. The first resource can meet the transmission requirement of similar XR service types, but the gNB has high detection complexity and poor use efficiency. And determining the distribution of the actual data transmission in any period of the periodic resource through the second indication information, thereby determining the transmission occasion of the actual data transmission. The transmission frequency of the first indication information is lower than that of the second indication information and the third indication information. On one hand, the advantages of small burden of configuration information and good real-time resource use performance in CG PUSCH resource allocation by the first resource related configuration are utilized, and on the other hand, the problem of high gNB detection complexity and the problem of low CG PUSCH resource use efficiency can be improved by determining the second resource through a set transmission mode. The gNB and the UE consider the first indication information unchanged before the second indication information is updated. In this way, indexes such as service data transmission delay, reliability, gNB detection complexity, CG PUSCH resource use efficiency and the like can be balanced among the transmission frequency of the second indication information, the set transmission mode and the selected target transmission mode.
