Description

Scheduling processing method and device, communication equipment and storage medium

Technical Field

The present disclosure relates to, but is not limited to, the field of wireless communication technology, and in particular to a scheduling processing method and apparatus, a communication device, and a storage medium.

Background technique

Extended Reality (XR) services refer to services that use computers and/or wearable devices for human-computer interaction or human-to-human communication. Therefore, XR services need to transmit a large amount of video data streams, and the data packets of XR services are usually relatively large. At the same time, considering the impact of interactivity on user experience, XR services also have strict requirements on data transmission latency.

Since the data packets of XR services are large, the transmission of a data packet of the XR service may require multiple physical uplink shared channels (PUSCH) or physical downlink shared channels (PDSCH). If a single downlink control information (DCI) is used to schedule the transmission of a single PUSCH or PDSCH, the DCI overhead will be large; or if a DCI is used to schedule multiple PUSCHs or PDSCHs and there are unavailable resources among the scheduled resources, it will lead to resource fragmentation and a certain transmission delay.

In order to facilitate the understanding of those skilled in the art, the embodiments of the present disclosure list multiple implementation methods to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the multiple embodiments provided by the embodiments of the present disclosure can be executed separately, or can be executed together with the methods of other embodiments of the embodiments of the present disclosure, or can be executed together with some methods in other related technologies separately or in combination; the embodiments of the present disclosure do not limit this.

It should be noted that when multiple execution entities are involved in the embodiments of the present disclosure, when one execution entity sends a transmission to another execution entity, it may refer to one execution entity sending the transmission directly to another execution entity, or it may refer to one execution entity sending the transmission to another execution entity through any other device; this is not limited in the embodiments of the present disclosure.

In order to better understand the technical solutions described in any embodiment of the present disclosure, first, some related technologies are described:

For Multi-PXSCH scheduling. In the Rel-15 to Rel-17 stages, in order to improve the efficiency of uplink scheduling and reduce the delay, signaling overhead and user blind detection complexity caused by scheduling multiple PUSCHs with multiple DCIs; 3GPP introduced the Multi-PXSCH scheduling method in the B52.6GHz frequency band. The Multi-PXSCH scheduling method can use a single DCI to schedule multiple time-domain continuous or non-continuous PUSCH or PDSCH data transmissions. It is also stipulated that the number of time-domain orthogonal frequency division multiplexing (OFDM) symbols occupied by each PUSCH or PDSCH scheduled by the Multi-PXSCH scheduling method can be different, but the frequency domain resources must be the same.

For UL CI and DL PL. In order to ensure that Ultra-Reliable Low-Latency Communications (URLLC) services can be transmitted first when conflicts occur with Enhanced Mobile Broadband (eMBB) services, 3GPP introduced two types of multicast DCI, UL CI and DL PI, in the Rel-15 and Rel-16 stages respectively. Among them, UL CI is carried by DCI format 2_4 and is used to instruct the UE to cancel the transmission on the specified resources in the scheduled PUSCH or SRS. DL PI is carried by DCI format 2_1 and is used to indicate that the transmission on the specified resources in the PDSCH received by the UE has been preempted; here, DL PI is used to indicate that there is no need to demodulate and decode the transmission on the specified resources in the PDSCH received by the UE.

In the Rel-18 stage, 3GPP RAN1 has made technical enhancements for XR services in terms of power saving and capacity improvement. Dynamic scheduling enhancement is one of the target research directions for improving capacity. Since XR data packets are large, the transmission of a data packet may require multiple PUSCHs or PDSCHs to complete. If a single DCI is used to schedule a single transmission, it will result in DCI overhead. In response to this problem, a series of companies proposed in the RAN1#109 meeting that the Multi-PXSCH scheduling method in Rel-17B52.6GHz can be introduced into the XR service to adapt to the characteristics of XR service data packets with large data packets and strict latency requirements; this Multi-PXSCH scheduling method can reduce latency by enabling continuous data transmission and reduce DCI signaling overhead.

Since the data packets of XR services are large and have strict requirements on latency, they need to occupy a wider frequency range during transmission. The current Multi-PXSCH scheduling method in Rel-17B52.6GHz requires that multiple PUSCHs or PDSCHs scheduled occupy the same frequency resources. However, there may be unavailable time-frequency resources in each time slot, such as resources in different transmission directions in a full-duplex time slot, resources allocated to other UEs for high-priority transmission, etc.; this makes it impossible for the base station to schedule time-domain continuous resources through the Multi-PXSCH method. If Multi-PXSCH is used to schedule non-continuous resources in the time domain, on the one hand, it will lead to resource fragmentation, and on the other hand, it will cause a certain delay due to not making the best use of resources that are closer to the front in the time domain.

For example, when a large data packet arrives, due to the existence of uplink resources in the full-duplex time slot, the base station cannot use the Multi-PDSCH method to schedule time-domain continuous downlink transmission, and can only adopt one of the following two scheduling methods:

Scheduling method 1: Use Multi-PDSCH to schedule two discontinuous PDSCH resources in the time domain, as shown in Figure 2. This scheduling method will lead to resource fragmentation and a certain transmission delay.

Scheduling method 2: Use multiple DCIs to schedule multiple PDSCH resources respectively, as shown in Figure 3. This scheduling method will generate DCI overhead and reduce the utilization efficiency of downlink resources.

The present disclosure provides a scheduling processing method, which is executed by a base station, including: sending a first DCI, wherein the first DCI indicates unavailable resources. Here, the first DCI indicating unavailable resources may be: the first DCI indicates unavailable resources in a multi-physical uplink shared channel or a physical downlink shared channel (Multi-PXSCH). Here, the unavailable resources include: unavailable time-frequency resources.

As shown in FIG4 , an embodiment of the present disclosure provides a scheduling processing method, which is executed by a base station and includes:

Step S41: Send a first DCI, wherein the first DCI is used to indicate unavailable resources in a multiple physical shared channel scheduled by a second DCI; wherein resources other than the unavailable resources in the resources scheduled by the second DCI are available resources.

In one embodiment, the multiple physical shared channels may be multiple physical uplink shared channels and/or physical downlink shared channels. Exemplarily, the multiple physical shared channels may be multiple physical uplink shared channels or multiple physical downlink shared channels (Multi-PXSCH).

In one embodiment, when the first DCI indicates unavailable resources in Multi-PXSCH, resources other than the unavailable resources in the resources occupied by Multi-PXSCH are available resources; and the available resources are used for transmission.

In one embodiment, the available resources may be available for transmission. The available resources may be available time-frequency resources.

In one embodiment, the base station may be, but is not limited to, at least one of the following: a 3G base station, a 4G base station, a 5G base station, and other evolved base stations. The scheduling processing method provided in the embodiment of the present disclosure may also be executed by an access network device, which may be, but is not limited to, a base station; the access network device may be a flexibly arranged logical node or function or an entity that implements a function in the access network, etc.

In one embodiment, sending the first DCI in step S41 may include: sending the first DCI to at least one UE. In the embodiment of the present disclosure, at least one is one or more; and a plurality is two or more.

In one embodiment, the UE may be any mobile terminal or a fixed terminal, for example, the UE may be, but is not limited to, a mobile phone, a computer, a server, a wearable device, a game control platform, a multimedia device, or any sensor.

In an embodiment, the first DCI and the second DCI may be any type of DCI.

In another embodiment, the first DCI is an indication DCI; and the second DCI is a scheduling DCI.

In one embodiment, the first DCI is used to indicate unavailable resources for uplink transmission in Multi-PXSCH or a physical shared channel, and/or, to indicate unavailable resources for downlink transmission in Multi-PXSCH or a physical shared channel. Here, the unavailable resources for uplink transmission in the physical shared channel may be: unavailable resources in PUSCH; and/or, the unavailable resources for downlink transmission in the physical shared channel may be: unavailable resources in PDSCH.

In an embodiment of the present disclosure, a base station sends a first DCI, wherein the first DCI is used to indicate unavailable resources in a multi-physical shared channel scheduled by a second DCI, and resources other than the unavailable resources in the resources occupied by the second DCI are available resources; in this way, transmission, such as transmission of a relatively large data packet service, can fully utilize the available resources scheduled in the second DCI to complete the transmission as soon as possible, thereby reducing the transmission delay.

In the embodiments of the present disclosure, available resources can be fully utilized for transmission, the occurrence of transmission resource fragmentation can be reduced, and resources at a more forward position in the time domain can be used for transmission, thereby reducing the transmission delay. In addition, since multiple physical shared channels (such as PDSCH and/or PUSCH) can be scheduled without multiple DCIs, it is also beneficial to reduce the DCI overhead.

It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

As shown in FIG5 , an embodiment of the present disclosure provides a scheduling processing method, which is executed by a base station and includes:

Step S51: Send a second DCI, where the second DCI is used to schedule available resources for transmission.

In some embodiments of the present disclosure, the available resources may be the available resources in step S41. Exemplarily, the available resources are resources other than the unavailable resources in the resources in the second DCI.

Of course, in other embodiments, the second DCI may be used to schedule available resources in the resources occupied by the Multi-PXSCH for transmission. The resources occupied by the Multi-PXSCH may be resources scheduled by the second DCI.

In an embodiment, the second DCI may be any type of DCI.

In another embodiment, the second DCI may be a scheduling DCI. Here, the second DCI may be used to schedule at least one PDSCH and/or at least one PUSCH.

In one embodiment, sending the second DCI in step S51 may include: sending the second DCI to at least one UE.

Exemplarily, as shown in Figure 6, the base station sends a first DCI, wherein the first DCI is used to indicate unavailable resources in the physical shared channel; the base station sends a second DCI after sending the first DCI, wherein the second DCI is used to schedule PDSCH other than unavailable resources in the occupied resources and/or to schedule PUSCH other than unavailable resources in the resources occupied by PUSCHS; here, the base station can transmit on these available PDSCHs and/or these PUSCHs.

Thus, in the embodiments of the present disclosure, unavailable resources in the physical shared channel can be indicated by a first DCI, and available resources (multiple PDSCH resources) other than the unavailable resources in the physical shared channel can be scheduled for transmission in a second DCI. Compared with the related art that uses Multi-PDSCH to schedule two PDSCH resources in succession (for example, the scheduling method shown in FIG. 2 ), the occurrence of fragmentation of scheduled transmission resources can be reduced, and the available resources can be fully utilized to complete the transmission, thereby reducing the delay; or, compared with the related art that uses multiple DCIs to schedule multiple PDSCHs respectively (for example, the scheduling method shown in FIG. 3 ), only one second DCI can be used to schedule multiple PDSCHs or multiple PUSCHs, thereby reducing the DCI overhead.

In some embodiments, the first DCI includes:

UL CI; UL CI is used to indicate unavailable resources in Multi-PXSCH transmission;

and / or,

DL PI; DL PI is used to indicate unavailable resources in Multi-PXSCH transmission.

In one embodiment, DL CI is used to indicate unavailable resources for uplink transmission in Multi-PXSCH transmission.

In one embodiment, DL PI is used to indicate unavailable resources for downlink transmission in Multi-PXSCH transmission.

In some embodiments, the first DCI includes:

and / or,

As shown in FIG. 7 , an embodiment of the present disclosure provides a scheduling processing method, which is executed by a base station and includes:

Step S71: Send UL CI, where UL CI is used to indicate unavailable resources in multiple PUSCHs scheduled by the second DCI; and/or send DL PI, where DL PI is used to indicate unavailable resources in multiple PDSCHs scheduled by the second DCI.

In one embodiment, sending UL CI in step S71 may be: sending UL CI to at least one UE.

In one embodiment, sending DL PI in step S71 may be: sending DL PI to at least one UE.

In one embodiment, UL CI includes: a first indication bit; wherein,

The first indication bit is a first value, which is used to indicate cancellation of transmission on a specified resource in a scheduled PUSCH or SRS;

or,

Here, the transmission on the specified resource is canceled, which can be described in the communication protocol as: cancels the corresponding UL transmission.

Here, canceling the transmission on the resources specified in the scheduled PUSCH or SRS may be not sending the transmission on the resources specified in the scheduled PUSCH or SRS. Exemplarily, the first indication bit is a first value, which is used to indicate that the UE does not send the transmission on the resources specified in the scheduled PUSCH or SRS.

Exemplarily, the first indicator bit in the UL CI may be any bit or a predetermined bit in the UL CI; the predetermined bit may be a reserved bit or a preset bit in the UL CI; the first indicator bit may be one bit or multiple bits. For example, the first indicator bit may be a first value such as "0" or "00"; or the first indicator bit may be a second value such as "1" or "11".

Exemplarily, as shown in FIG8 , the base station sends a UL CI to at least one UE, wherein the UL CI includes a first indicator bit; the first indicator bit is 1 bit; when the first indicator bit is "1" (i.e., the second value), it is used to indicate unavailable resources of the PUSCH in the multiple physical transmission channels. If the UE receives the second DCI, it can transmit based on the PUSCH other than the unavailable resources in the resources scheduled by the second DCI.

In the above example, if the first indicator bit is "0" (that is, the first value), it is determined that the UL CI is a UL CI for conventional use; at this time, the UL CI is used to indicate the cancellation of the transmission on the specified resources in the scheduled PUSCH or SRS.

In this way, in the disclosed embodiment, the unavailable resources of PUSCH in the multi-physical shared channel can be indicated by UL CI, which increases the flexibility of scheduling and expands the application scenarios of UL CI. In addition, the adaptation scenarios of the multi-physical shared channel (or Multi-PXSCH) scheduling method can also be expanded.

In one embodiment, DL PI includes: a second indicator bit; wherein,

or,

Here, the transmission on the specified resources in the PDSCH that the UE has received may be preempted if: the base station can specify the resources in the PDSCH that the UE has received for transmission, and at the same time, a more important PDSCH is transmitted simultaneously; the transmission in the more important PDSCH can be decoded, while the transmission in the specified resources in the PDSCH that the UE has received cannot be decoded, in which case the transmission on the specified resources in the PDSCH that the UE has received is preempted (by the more important PDSCH).

Here, the UE may assume no transmission is intended for the UE.

Exemplarily, the second indicator bit in the DL PI may be any bit or a predetermined bit in the DL PI; the predetermined bit may be a reserved bit or a preset bit in the DL PI; the second indicator bit may be one bit or multiple bits. For example, the first indicator bit may be the third value: the second indicator bit may be "0" or "00", etc.; or the second indicator bit may be the fourth value: the second indicator bit may be "1" or "11", etc.

Exemplarily, as shown in FIG9 , the base station sends a DL PI to at least one UE, wherein the DL PI includes a second indicator bit; the second indicator bit is 1 bit; when the second indicator bit is "1" (i.e., the fourth value), it is used to indicate the unavailable resources of the PDSCH in the multi-physical sharing. If the UE receives the second DCI, it can transmit based on the PDSCH other than the unavailable resources in the resources scheduled by the second DCI.

In the above example, if the second indicator bit is "0" (that is, the third value), it is determined that the DL PI is a DL PI for conventional use; at this time, the DL PI is used to indicate that the transmission on the specified resources in the received PDSCH is preempted.

In this way, in the disclosed embodiment, the unavailable resources of PDSCH in the multi-physical shared channel can be indicated by DL PI, which increases the flexibility of scheduling and expands the application scenarios of DL PI. In addition, the adaptation scenarios of the multi-physical shared channel (or Multi-PXSCH) scheduling method can also be expanded.

The embodiment of the present disclosure provides a scheduling processing method, which is executed by a base station, including: sending a predetermined duration; wherein the predetermined duration is the timing duration of a timer of a UE. Here, the timer is a timer of the UE; the UE determines that a UL CI for indicating unavailable resources and/or a DL PI for indicating unavailable resources is received, and determines to start a timer, and the timing duration of the timer is the predetermined duration.

As shown in FIG. 10 , an embodiment of the present disclosure provides a scheduling processing method, which is executed by a base station and includes:

Step S101: Send a predetermined duration; wherein the predetermined duration is the timing duration of the UE's timer; the timer is started after the UE receives a UL CI for indicating unavailable resources and/or a DL PI for indicating unavailable resources.

In some embodiments of the present disclosure, the unavailable resources are the unavailable resources in the above embodiments; the UL CI and DL PI are the UL CI and DL PI in the above embodiments, respectively.

Here, UL CI is used to indicate unavailable resources in the PUSCH of the physical shared channel; and/or, DL PI is used to indicate unavailable resources in the PDSCH of the physical shared channel.

In one embodiment, the RRC message is any type of RRC message, for example, the RRC message may be, but is not limited to, an RRC connection establishment message or an RRC reestablishment message.

In one embodiment, the predetermined duration may be preconfigured by the base station or determined based on historical experience information or based on a communication protocol or based on negotiation between the base station and the UE.

Thus, in the disclosed embodiment, the base station may send a predetermined duration so that when the UE receives the UL CI and determines that the UL CI indicates unavailable resources, a timer with a predetermined duration is started, which is beneficial for the UE to detect the second DCI (i.e., the scheduling DCI) and schedule the PUSCH for transmission within the timing duration of the timer, thereby facilitating the UE to make full use of the available resources for transmission. Furthermore, for a UE that does not receive the second DCI within the timing duration of the timer, it can be known that it is not the target UE for the base station to send the second DCI.

Furthermore, the embodiment of the present disclosure can carry a predetermined duration through an RRC message for transmission, and realize two functions through one RRC message, thereby improving the utilization rate of the RRC message and reducing the signaling overhead.

In some embodiments, the first DCI carries a predetermined duration.

In some embodiments, DL PI includes: a second indicator bit; wherein,

The second indicator bit is the third value, used to indicate that the transmission on the specified resources in the PDSCH received by the UE is preempted; or, the second indicator bit is the fourth value, used to indicate the unavailable resources in the multiple PDSCHs scheduled by the second DCI.

For the above implementation methods, please refer to the description on the base station side, which will not be repeated here.

As shown in FIG. 12 , an embodiment of the present disclosure provides a scheduling processing method, which is executed by a UE and includes:

Step S1201: receiving a second DCI;

Step S1202: Transmit based on available resources scheduled by the second DCI.

In one embodiment, step S1202 may be: transmitting based on available resources in the resources scheduled by the second DCI.

In some embodiments of the present disclosure, the second DCI may be the second DCI in the above embodiment; the predetermined duration may be the predetermined duration in the above embodiment; and the RRC message may be the RRC message in the above embodiment.

Here, the UE can transmit based on resources other than unavailable resources in the resources occupied by the Multi-PXSCH scheduled by the second DCI

Here; the available resources may be PUSCH resources and/or PDSCH resources.

In one embodiment, step S1201 may be: receiving a second DCI sent by a base station.

The present disclosure provides a scheduling processing method, which is executed by a UE and includes:

Get the scheduled duration;

Here, UL CI indicates unavailable resources in the PUSCH scheduled by the second DCI; and/or DL PI indicates unavailable resources in the PDSCH scheduled by the second DCI.

In some embodiments, obtaining the predetermined duration includes: receiving an RRC message, wherein the RRC message carries the predetermined duration.

In another embodiment, obtaining the predetermined duration includes: obtaining the predetermined duration based on the first DCI. Here, the first DCI carries the predetermined duration.

An embodiment of the present disclosure provides a scheduling processing method, which is executed by a UE, and includes: based on receiving a second DCI within a timing duration of a timer, transmitting based on available resources scheduled by the second DCI.

The disclosed embodiment provides a scheduling processing method, which is executed by a UE, including: based on the fact that the second DCI is not received within the timing duration of the timer, no transmission operation related to the first DCI and/or the second DCI is performed. Here, when the UE does not receive the second DCI, the transmission process is terminated. At this time, it can also be determined that the UL CI and/or DL PI received by the UE is not sent to itself, and it is determined that the UL CI and/or DL PI is sent to other UEs in the cell.

Exemplarily, UL CI and DL PI are multicast DCI, and the multicast DCI (i.e., UL CI and DL PI) may be directed to at least one UE in a cell; therefore, UEs that need or do not need to perform physical shared channel transmission in the same cell may receive UL CI and/or DL PI. The base station may send a predetermined duration through an RRC message or through UL CI and/or DL PI, and after the UE receives the predetermined duration, the timing duration of the timer of the timer is set to the predetermined duration.

If the UE receives UL CI, it determines whether the UL CI indicates cancellation of transmission on the scheduled PUSCH or specified resources in the SRS, or indicates unavailable resources in the PUSCH scheduled by the second DCI; if it is determined that the UL CI indicates unavailable resources for the PUSCH scheduled by the second DCI, the timer is started. The UE detects the second DCI before the timer expires (i.e., within the timing duration), and transmits based on the PUSCH resources other than the unavailable resources in the resources scheduled by the second DCI; if the second DCI is not detected before the timer expires, the transmission operation related to the first DCI and/or the second DCI is not performed.

Alternatively, if the UE receives a DL PI, it determines whether the DL PI indicates that the transmission on the designated resources in the received PDSCH is preempted or indicates the available resources of the PDSCH scheduled by the second DCI; if it is determined that the DL PI indicates the unavailable resources of the PDSCH in the second DCI scheduling, the timer is started. The UE detects the second DCI before the timer expires (i.e., within the timing duration), and transmits based on the PDSCH resources other than the unavailable resources in the resources scheduled by the second DCI; if the second DCI is not detected before the timer expires, the transmission operation related to the first DCI and/or the second DCI is not performed.

Thus, in an embodiment of the present disclosure, the UE can determine the available transmission resources in the resources scheduled by the second DCI through the received first DCI, and can set the timing duration of the timer through the received predetermined duration; thus, it can be detected whether there is a second DCI scheduling transmission resources within the timing duration of the timer, and if so, transmission can be performed based on resources other than the unavailable resources in the resources scheduled by the second DCI, thereby making full use of the available resources to complete the transmission as soon as possible, and reducing the service delay; or, if the second DCI scheduling transmission resources is not detected within the timing duration of the timer, it is determined that the received first DCI is not sent by the base station to itself, and thus the relevant transmission operation can be not performed.
