The method introduces the control resource allocation information of the first service, reduces the resource space of the local terminal monitoring signaling to the monitoring resource space under the condition that the second service processed by the local terminal is not influenced, avoids the problem of overlarge monitoring burden of a downlink channel caused by monitoring the whole preset resource space, and reduces the consumption of electric energy.
Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a method for processing and sending a preemption indication signaling, a terminal and a base station.
Background
Because the resource management is performed on the eBB service terminal and the URLLC service terminal by adopting a static or semi-static independent resource division allocation mode (for example, a multiplexing mode of independent frequency domain resource division is adopted), a lower resource utilization rate is inevitably caused, and therefore, a dynamic resource sharing management mode is adopted for the eBB service terminal and the URLLC service terminal, namely, the URLLC service is a technology for sharing transmission with the eBB service in the eBB service resource by using Mini-slot granularity in a mode of seizing, punching or overlapping and the like due to the low time delay requirement of the URLLC service. The technology can enable the 5G system to simultaneously provide reliable service meeting the expected indexes of 5G for services with different time delay, reliability and transmission efficiency requirements. And introducing a resource indication physical layer control signaling, namely a preemption indication signaling, for downlink eMBB service terminal and URLLC service terminal dynamic resource sharing.
According to the research on the technology of how to guarantee the high reliability of the URLLC service while achieving low delay (including how to achieve the high reliability of the uplink and downlink control channels) by the 3GPP working group, it is considered that there are mainly 3 means for guaranteeing the reliability of the downlink control channel (PDCCH) carrying the downlink scheduling command: (1) increasing the aggregation level of the PDCCH signaling (the aggregation level specified by the current 3GPP NR is {1, 2, 4, 8}, if the reliability below the single time of URLLC service scheduling needs to be ensured, for a cell edge user, the aggregation level needs to be extended and supported by 16 or 32); (2) the PDCCH dispatching signaling length is reduced, the result that the URLLC service needs to adopt short-time high-bandwidth frequency spectrum resource dispatching due to the low time delay requirement of the URLLC service is considered, the frequency resource of the URLLC service can adopt coarser indication granularity, and the PDCCH dispatching signaling length can be reduced in a limited way; (3) the continuous repeated or multiple-time transmission technology is adopted, and obviously, the application of the technology is contradictory to the requirement of low time delay, so that the application limitation is strong.
On one hand, because of the requirement of low time delay for the users of the URLLC in the cell, the aggregation level that the downlink scheduling PDCCH of the URLLC may adopt is 8; on the other hand, the downlink scheduling signaling of URLLC cannot be too short, and if it is too short, the code gain of the channel coding with short code length will be lower, which affects the reliability of the downlink scheduling channel. Thus, even for the URLLC users in the cell, the overhead of its downlink control channel is relatively large. The PDCCH signaling with a higher aggregation level not only has a problem of large resource overhead, but also causes a blocking rate of control resource allocation to other users due to the resource and control resource allocation priority of the URLLC service. The increase of the blocking rate means that the scheduling opportunity/transmission rate of the eMB user in the cell is reduced, so that the cell resource is wasted, the utilization rate of the wireless resource is low, the monitoring burden of the user in the cell on the scheduling signaling is heavier, and the power consumption is increased meaningless.
In addition, the triggering time of the URLLC service is completely random, and the URLLC service resource is scheduled by using high-bandwidth frequency resource, so that most terminals in a cell need to monitor the preemption indication principle signaling in actual operation, which causes the terminal to increase the PDCCH channel monitoring burden instantaneously and meaninglessly when the URLLC service and the eMBB service are concurrent.
Therefore, in the process of implementing the embodiment of the present invention, the inventor finds that in the existing system for sharing URLLC service and eMBB service, most terminals need to monitor the preemption indication principle signaling, and the PDCCH channel monitoring is overloaded and consumes much power.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart illustrating a method for processing preemption indication signaling according to this embodiment, and referring to fig. 1, the method includes:
101: after receiving a preemption indication signaling corresponding to a first service, judging whether a local terminal meets the condition of processing the preemption indication signaling or not according to the preemption indication signaling;
102: if the local terminal is judged not to meet the condition for processing the preemption indication signaling, judging whether the processing of a preset second service by the local terminal is influenced or not according to the preemption indication signaling;
103: if the local terminal judges that the processing of the second service is not influenced, a first resource space occupied by a control resource corresponding to the first service is obtained according to control resource allocation information in the preemption indication signaling, and a resource space not occupied by the first resource space in a preset resource space is used as a monitoring resource space for the local terminal to monitor the signaling;
the preemption indication signaling is a signaling carrying service resource allocation information of the first service and the control resource allocation information, and the preset resource space is a resource space for sending control resources and signaling in a resource space corresponding to a downlink channel.
It should be noted that the method provided in this embodiment is executed by a terminal (e.g., a mobile phone, a computer). And the preemption indication signaling is sent to the terminal by the base station. Generally, the method is applicable to the case of shared transmission of two services, for example, the eMBB service and the URLLC service, where the first service is the URLLC service and the second service is the eMBB service. I.e. the case where the terminal managed by the base station handles both the eMBB traffic and the URLLC traffic. The resource space refers to a time domain space and a frequency domain space.
The preemption indication signaling is a signaling carrying service resource allocation information and control resource allocation information of the first service. The service resource allocation information specifies a resource space in a downlink channel (for example, PDCCH) occupied by the service resource of the first service when transmitting, for example, the service resource allocation information specifies that the resource space in the downlink channel occupied by the service resource of the first service when transmitting is a second resource space.
The control resource allocation information specifies a resource space in a downlink channel occupied by the control resource of the first service during transmission. For example, the control resource allocation information specifies that a resource space in the downlink channel occupied by the control resource of the first service during transmission is a first resource space. The preset resource space is a resource space for transmitting control resources and signaling in the downlink channel, so the first resource space is a part of the preset resource space. Accordingly, the second resource space is no longer within the resource space range defined by the preset resource space.
Typically, the preemption indication command is generated in the format of the common DCI signaling. In order to enable the terminal configured by the base station to monitor the preemption indication signaling to receive the preemption indication signaling, the preemption indication signaling is sent through a resource space specified in a preset resource space and used for sending a common signaling.
The process of replacing the resource space monitored by the local terminal for the signaling with the monitored resource space can be realized by changing the information of the monitored resource space and refreshing the information, or can be realized by changing the information of the monitored resource space and restarting the local terminal, which is not particularly limited in this embodiment.
Generally, the local terminal in this embodiment is configured to process the second service, but after receiving the preemption indication signaling, process the preemption indication signaling according to the above steps 101 to 103. For example, the first service is URLLC service, and the second service is eMBB service. After receiving a preemption indication signaling of a URLLC service sent by a base station, a terminal judges whether the local terminal meets the condition for processing the preemption indication signaling according to the preemption indication signaling, if not, judges whether the preemption indication signaling affects the processing of the local terminal on an eMBB service, if not, obtains a first resource space occupied by control resources of the URLLC service according to the preemption indication signaling, thereby not monitoring the signaling of the first resource space, but monitoring the signaling of only the monitoring resource space not occupied by the first resource space.
In the method, a base station generates a preemption indication signaling carrying control resource allocation information of a first service, and sends the preemption indication signaling to a terminal configured to receive the preemption indication signaling. And after the terminal receives the preemption indication signaling, if the preemption indication signaling does not influence the processing of the second service by the local terminal, replacing the resource space monitored by the signaling by the local terminal into the resource space which is not occupied by the control resource corresponding to the first service in the preset resource space. In the method, the base station introduces the control resource allocation information of the first service in the process of sending the preemption indication signaling, and under the condition that the second service processed by the local terminal is not influenced, the resource space of the local terminal monitoring signaling is reduced to the monitoring resource space which is not occupied by the control resource corresponding to the first service in the preset resource space, so that the problem of overlarge monitoring burden of a downlink channel caused by monitoring the whole preset resource space is avoided, and the consumption of electric energy is reduced.
Further, on the basis of the foregoing embodiment, the determining, according to the preemption indication signaling, whether the processing of the preset second service by the local terminal is affected includes:
acquiring a second resource space occupied by a service resource corresponding to the first service according to the service resource allocation information, and acquiring a third resource space occupied by a service resource corresponding to the second service received by the local terminal;
and judging whether the second resource space and the third resource space have overlapped resource spaces, if so, judging that the processing of the second service by the local terminal is influenced, and storing the preemption indication signaling, otherwise, judging that the processing of the second service by the local terminal is not influenced.
The third resource space may be obtained from signaling sent by the base station for processing the second service and received by the local terminal. That is, the resource space occupied by the service resource of the second service, which is the third resource space, is obtained through the service resource allocation information about processing the second service sent by the base station. The overlapping of the second resource space and the third resource space means that if a time domain space overlapping in a time domain exists in the second resource space and the third resource space and a frequency domain space overlapping in a frequency domain also exists in the time domain space, the frequency domain space is a space where both the time domain and the frequency domain overlap, that is, an overlapping resource space.
For example, if there is an overlapping resource space between a third resource space occupied by a service resource of an eMBB service received by a local terminal and a second resource space occupied by a service resource of a URLLC service, the processing of the eMBB service by the local terminal is affected, otherwise, it is determined that the processing of the eMBB service by the local terminal is not affected.
The present embodiment provides a method for processing a preemption indication signaling, and the method can realize a fast and accurate determination on whether a second service processed by a local terminal is affected by preempting service resource allocation information in the indication signaling and a third resource space occupied by a service resource corresponding to the second service received by the local terminal.
Further, on the basis of the above embodiments, the method further includes:
if the processing of the second service by the local terminal is affected, determining the overlapping resource space according to the preemption indication signaling and the third resource space, acquiring the service resource of the second service received in the overlapping resource space, taking the service resource as an affected service resource, and modifying the affected service resource to obtain a modified service resource;
and in the service resources of the second service, replacing the affected service resources with the corrected service resources to obtain the corrected service resources of the second service.
It should be noted that the method provided in this embodiment is used in the process of decoding the service resource corresponding to the second service. For example, a value corresponding to each bit of the affected service resource is replaced with a preset value (e.g., 0 or 1), and the replaced service resource is the modified service resource. And deleting the affected service resources from the service resources of the second service, and adding the corrected service resources to the positions of the affected service resources to obtain the corrected service resources of the second service.
The embodiment provides a processing method for preempting an indication signaling, and the method provides a method for how to process a service resource of an affected second service received by a local terminal.
Further, on the basis of the foregoing embodiments, the determining, according to the preemption indication signaling, whether the local terminal meets a condition for processing the preemption indication signaling includes:
acquiring a resource space occupied by a service resource used by the local terminal for receiving a service to be processed according to a downlink service scheduling signaling received in advance, wherein the resource space is used as an original resource space, and acquiring the second resource space according to the service resource allocation information;
and if the original resource space is the same as the second resource space, judging that the local terminal meets the condition for processing the preemption indication signaling, otherwise, judging that the local terminal does not meet the condition for processing the preemption indication signaling.
It should be noted that the downlink service scheduling signaling is a signaling on how the local terminal receives and processes the service to be processed, and the downlink service scheduling signaling includes a resource space occupied by the service resource of the service to be processed.
For example, the local terminal receives a downlink service scheduling signaling of the URLLC service, and a resource space occupied by a service resource for receiving the URLLC service specified in the downlink service scheduling signaling is an original resource space. If the second resource space occupied by the service resource corresponding to the first service specified in the service resource allocation information in the preemption indication signaling is the same as the original resource space, judging that the local terminal meets the condition for processing the preemption indication signaling, otherwise, judging that the local terminal does not meet the condition for processing the preemption indication signaling.
The embodiment provides a method for processing a preemption indication signaling, which judges whether a local terminal accords with the processing of the preemption indication signaling, and realizes quick and accurate judgment on whether the local terminal accords with the processing of the preemption indication signaling.
Fig. 2 shows a block diagram of a terminal for processing preemption indication signaling according to this embodiment, and referring to fig. 2, the terminal for processing preemption indication signaling includes a first judging module 201, a second judging module 202 and a processing module 203, wherein,
a first determining module 201, configured to determine, after receiving a preemption indication signaling corresponding to a first service, whether a local terminal meets a condition for processing the preemption indication signaling according to the preemption indication signaling;
a second determining module 202, configured to determine, according to the preemption indication signaling, whether processing of a preset second service by the local terminal is affected if it is determined that the local terminal does not meet the condition for processing the preemption indication signaling;
a processing module 203, configured to obtain, according to the control resource allocation information in the preemption indication signaling, a first resource space occupied by a control resource corresponding to the first service if it is determined that processing of the second service by the local terminal is not affected, and use a resource space not occupied by the first resource space in a preset resource space as a monitoring resource space for monitoring the signaling by the local terminal;
the preemption indication signaling is a signaling carrying service resource allocation information of the first service and the control resource allocation information, and the preset resource space is a resource space for sending control resources and signaling in a resource space corresponding to a downlink channel.
The terminal for processing the preemption indication signaling provided in this embodiment is applicable to the method for processing the preemption indication signaling provided in the above embodiment, and is not described herein again.
The embodiment provides a terminal for processing a preemption indication signaling, and after receiving the preemption indication signaling, if the preemption indication signaling does not affect the processing of a second service by a local terminal, a resource space monitored by the local terminal for the signaling is replaced by a resource space which is not occupied by a control resource corresponding to a first service in a preset resource space. In the method, the base station introduces the control resource allocation information of the first service in the process of sending the preemption indication signaling, and under the condition that the second service processed by the local terminal is not influenced, the resource space of the local terminal monitoring signaling is reduced to the monitoring resource space which is not occupied by the control resource corresponding to the first service in the preset resource space, so that the problem of overlarge monitoring burden of a downlink channel caused by monitoring the whole preset resource space is avoided, and the consumption of electric energy is reduced.
Fig. 3 is a flowchart of a method for sending preemption indication signaling according to this embodiment, and referring to fig. 3, the method includes:
301: generating an indication signaling carrying service resource allocation information and control resource allocation information corresponding to the first service, and taking the indication signaling as a preemption indication signaling;
302: configuring a terminal for monitoring the preemption indication signaling, and sending the preemption indication signaling to the terminal for monitoring the preemption indication signaling through a preset resource space;
and the preset resource space is used for sending control resources and signaling in the resource space corresponding to the downlink channel.
Further, the format of the preemption indication signaling is the same as the format of common signaling.
It should be noted that the method provided in this embodiment is executed by the base station. Generally, the method is applicable to the case of shared transmission of two services, for example, the eMBB service and the URLLC service, where the first service is the URLLC service and the second service is the eMBB service. Before the base station sends the signaling, the base station needs to configure the terminal receiving the signaling, and only the terminal configured by the base station to receive the signaling can receive the signaling sent by the base station. For example, before the base station sends the preemption indication signaling, it is necessary to configure terminals (usually a group of terminals) that receive the preemption indication signaling, and all terminals configured to receive the preemption indication signaling can receive the preemption indication signaling. In the situation of shared transmission of the eMBB service and the URLLC service, in order to ensure a low latency requirement of the URLLC service, before issuing a preemption indication signaling of the URLLC service, the base station configures all or part of terminals in a cell corresponding to the base station as terminals that receive the preemption indication signaling, and the terminals that receive the preemption indication signaling execute steps 101 to 103 provided in this embodiment to implement processing of the preemption indication signaling, processing of the affected second service, and updating a resource space of its own monitoring signaling into a monitored resource space.
In the preemption indication signaling, the Control resource allocation information of URLLC is appended behind the service resource allocation information, and the Control resource allocation information includes aggregation level and CCE (Control Channel Element, PDCCH transmitted on one or more CCEs) start position and repetition number, and is carried together in the preemption indication signaling and issued to the terminal at the same time.
For example, in an application scenario shared by URLLC and eMBB, a frequency band is 3.5GHz, a Bandwidth segment (Bandwidth Parts) shared by URLLC and eMBB is 20MHz, a carrier spacing is 15KHz, a total number of physical resource blocks PRB (physical resource blocks) is 100, and a time granularity is a finer granularity. The URLLC service uses 2 symbols Mini-Slot in a 14-symbol TTI (transmission time interval) of the eMBB service, and may use 3 bits to indicate the time domain resource location. While the frequency granularity may employ a coarser granularity. The 5G NR (radio access technology) system still uses the type 0 Resource allocation scheme of LTE, where the length P of a Resource Group RBG (Resource Block Group, which is a set of contiguous PRBs) is defined as 12, and a total of 3 bits are required to represent the frequency domain Resource location. The downlink control resource set (CORSET) loaded on the shared bandwidth segment keeps the capacity similar to that of LTE, occupies 3 symbols in the time domain, the total CCE capacity is 80, the value of the aggregation level of the URLLC downlink scheduling command can be selected from the set {4, 8, 16, 32} only, and only 2 bits are needed for representation; for aggregation level 4, the CCE of the URLLC downlink scheduling command may have a maximum possible starting position, which is more than 20 starting positions, and the starting positions are represented by 5 bits in total, but other aggregation levels need to indicate relatively few positions, and if joint coding is used for the aggregation level of URLLC and other CCE starting positions, a total of 6 bit positions is sufficient, so that the signaling format of the preemption indication command is as shown in fig. 4. Referring to fig. 4, the URLLC service resource time domain indication and the URLLC service resource frequency domain indication are service resource allocation information of the URLLC service, the aggregation level of the URLLC scheduling command and the CCE initial position of the URLLC scheduling command are control resource allocation information of the URLLC service, the service resource allocation information and the control resource allocation information are located behind the information domain, and the control resource allocation information is located behind the service resource allocation information. Table one shows the bit length occupied by each part in the preemption indication command, and table two shows the form of a codebook in which the aggregation level and CCE starting position of the URLLC scheduling command are jointly encoded. It should be noted that, in this example, the codebook shown in table two is a codebook designed by using a simpler design method, and can support the capacity of the control resource to reach 128 CCEs, and has a certain capability of supporting system upgrade.

The embodiment of the invention provides a method for sending a preemption indication signaling, wherein in the method, a base station generates the preemption indication signaling carrying control resource allocation information of a first service, and sends the preemption indication signaling to a terminal configured to receive the preemption indication signaling. And after the terminal receives the preemption indication signaling, if the preemption indication signaling does not influence the processing of the second service by the local terminal, replacing the resource space monitored by the signaling by the local terminal into the resource space which is not occupied by the control resource corresponding to the first service in the preset resource space. In the method, the base station introduces the control resource allocation information of the first service in the process of sending the preemption indication signaling, and under the condition that the second service processed by the local terminal is not influenced, the resource space of the local terminal monitoring signaling is reduced to the monitoring resource space which is not occupied by the control resource corresponding to the first service in the preset resource space, so that the problem of overlarge monitoring burden of a downlink channel caused by monitoring the whole preset resource space is avoided, and the consumption of electric energy is reduced.
Fig. 5 is a block diagram illustrating a structure of a base station for transmitting preemption indication signaling according to this embodiment, and referring to fig. 5, the base station for transmitting preemption indication signaling includes a generating module 501 and a transmitting module 502, wherein,
a generating module 501, configured to generate an indication signaling carrying service resource allocation information and control resource allocation information corresponding to a first service, as a preemption indication signaling;
a sending module 502, configured to configure a terminal that monitors the preemption indication signaling, and send the preemption indication signaling to the terminal that is configured to monitor the preemption indication signaling through a preset resource space;
and the preset resource space is used for sending control resources and signaling in the resource space corresponding to the downlink channel.
The base station for sending the preemption indication signaling provided in this embodiment is suitable for the sending method of the preemption indication signaling provided in the above embodiments, and is not described herein again.
The present embodiment provides a base station for sending a preemption indication signaling, where the base station generates a preemption indication signaling carrying control resource allocation information of a first service, and sends the preemption indication signaling to a terminal configured to receive the preemption indication signaling. And after the terminal receives the preemption indication signaling, if the preemption indication signaling does not influence the processing of the second service by the local terminal, replacing the resource space monitored by the signaling by the local terminal into the resource space which is not occupied by the control resource corresponding to the first service in the preset resource space. In the method, the base station introduces the control resource allocation information of the first service in the process of sending the preemption indication signaling, and under the condition that the second service processed by the local terminal is not influenced, the resource space of the local terminal monitoring signaling is reduced to the monitoring resource space which is not occupied by the control resource corresponding to the first service in the preset resource space, so that the problem of overlarge monitoring burden of a downlink channel caused by monitoring the whole preset resource space is avoided, and the consumption of electric energy is reduced.
As a specific example, fig. 6 shows a flowchart of a preemption indication signaling sending and using process, as shown in fig. 6, the process includes:
601: establishing a cell, and accessing eMBB UE to carry out service transmission; namely, the terminal corresponding to the eMBB service is accessed.
602: UE access of URLLC service; namely, the terminal corresponding to the URLLC service is accessed.
603: the network configures all UE to monitor the scheduling indication signaling; namely, the downlink service scheduling signaling and the preemption indication signaling sent by the base station are monitored.
604: URLLC downlink service data arrives; namely, the downlink traffic scheduling signaling of URLLC arrives.
605: the network issues URLLC resource scheduling command (downlink service scheduling signaling) and preemption indication signaling simultaneously.
606: all UEs receive the preemption indication signaling first.
607: judging whether the signaling is URLLC UE (judging whether the local terminal meets the condition for processing the preemption indication signaling), if so, executing 608, otherwise, executing 609, 608: continuously monitoring and processing the URLLC scheduling signaling;
609: and judging whether the service is the affected eMBB UE (judging whether the processing of the local terminal on the preset second service is affected), if so, executing step 610, and otherwise, executing step 611.
610: storing the preemption indication information to receive and process the subsequent transmission block (storing the preemption indication signaling);
611: and updating the search space (resource space for monitoring signaling) according to the URLLC scheduling control resource, and continuously monitoring other signaling (updating the search space no matter whether the resource of the eMBB service processed by the UE is scheduled or not).
The preemption indication signaling provided by this embodiment is independently issued by using a group common DCI signaling format, instead of being included in the downlink dedicated resource scheduling signaling. Once configured by the higher layer, the preemption indication signaling will be issued to inform the relevant UEs which resources are preempted. However, the triggering time of the URLLC service is completely random, the use of the preemption indication signaling cannot be completely realized by the fact that a high layer notifies some specific UEs in advance to monitor, and in addition, the URLLC service resource adopts the scheduling principle of high broadband frequency resources, which causes that most terminals in a cell need to monitor the preemption indication principle signaling in actual operation. As a result, the simultaneous URLLC service and eMBB service causes a significant increase in the PDCCH channel monitoring load of the terminal, which results in an unnecessary increase in power consumption. Therefore, the application of the preemption indication signaling technology should consider how to reduce the negative influence of URLLC downlink scheduling on the downlink control channel resources and the control channel monitoring by the terminal user.
In this embodiment, it is considered that the preemption indication signaling is issued in an independent group common downlink signaling manner, and in principle, this signaling may be monitored and received by any user in the cell. In addition, considering that the URLLC downlink resource scheduling is issued by adopting a smaller signaling length format as much as possible to increase the reliability of a PDCCH channel of the URLLC downlink resource scheduling, the resource scheduling information indicated by the preemption indication signaling to the affected UE is only part of the content of the URLLC downlink resource scheduling signaling, which shows that the indication information load of the preemption indication signaling is lighter, and more useful information can be completely transmitted to users in a cell. Therefore, the invention adds the information (including aggregation level, CCE starting position and repetition times) of URLLC downlink scheduling control resource allocation to the URLLC downlink service resource indication information, and the information are carried in the preemption indication signaling and are simultaneously issued to the users in the cell.
When the URLLC downlink service is triggered, the network may start the configuration for monitoring the preemption indication information for all users. And when the network issues the URLLC scheduling information, issuing a preemption indication signaling at the same time. The users affected by URLLC may confirm that their transmissions are affected according to the preemption indication information, and may only store the indication information for subsequent transmission and retransmission processing of the transport blocks. And other active users can simultaneously receive the preemption indication information and URLLC service UE downlink scheduling control resource information, confirm that no currently allocated resource is preempted according to the preemption indication information, or currently no pre-allocated resource but no monitoring preemption indication information is needed, and can continue to process the URLLC service UE downlink scheduling control resource information.
In this embodiment, the preemption indication signaling is extended, and on the basis that the existing indication information is used to indicate the function of receiving and processing the subsequent transmission block of the UE affected by the URLLC service, the indication information of the URLLC downlink control resource allocation is added, which can be used to guide other UEs in the cell to monitor the PDCCH, and save or reduce the workload of PDCCH monitoring.
