Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for indicating monitoring of uplink preemption information.
Background
The International Telecommunications Union (ITU) defines three main application scenarios for fifth generation (5G) mobile communication systems: enhanced Mobile Broadband (eMBB), such as 3D ultra high definition video; high reliability Low Latency Connection (URLLC), such as autopilot; large-scale Machine Type of Connection (mtc), such as the internet of things. Different scenarios have different latency and reliability requirements. For example, for a high-reliability low-latency connection scenario, the index of the control plane latency is 10 milliseconds (ms), and the index of the user plane latency is 0.5ms for uplink and 0.5ms for downlink; the performance indexes of the reliability are as follows: the accuracy of a 32-byte data packet transmitted within 1ms of user plane delay is more than 99.999%.
The third generation partnership project (3GPP) introduces a research on the multiplexing problem between uplink URLLC service and eMBB service, and proposes some uplink multiplexing methods.
For example, fig. 1 is a schematic diagram of multiplexing (overlapping) of URLLC service and eMBB service between different uplink users in the prior art, and fig. 1 shows the uplink multiplexing between users of different services, that is, a base station needs to respond to a scheduling request of a URLLC service user and allocate corresponding time-frequency domain resources; in order to ensure the low delay characteristic of the URLLC service, the allocated time-frequency domain resources are likely to overlap with the time-frequency domain resources previously allocated to the eMBB service users by the base station.
As shown in fig. 1, when an eMBB service user sends an eMBB scheduling request to a base station, the base station allocates corresponding time-frequency domain resources to the eMBB service user, and informs the allocated time-frequency domain resources to the eMBB service user through Downlink Control Information (DCI); after that, if the URLLC service user sends a URLLC scheduling request to the base station, when the base station allocates the time-frequency domain resources for the URLLC service user, the allocated time-frequency domain resources may overlap with the time-frequency domain resources already allocated to the eMBB service user. Since the URLLC service and the eMBB service belong to different users, the base station needs to notify the time-frequency domain resources allocated to the URLLC service user through DCI, and also needs to notify the eMBB service user of the information of the time-frequency domain resources allocated to the URLLC service user through DCI. After receiving the uplink preemption information, if the time-frequency domain resources occupied by the eMBB data to be sent by the eMBB service user overlap with the time-frequency domain resources indicated by the uplink preemption information (i.e., the time-frequency domain resources allocated to the URLLC service user), the eMBB service user performs puncturing (i.e., sending a part of data) or canceling (i.e., canceling data sending) on the eMBB data currently required to be sent.
In the method, because the URLLC service is unpredictable, all eMBB service users need to constantly monitor the downlink control channel containing the uplink preemption information to cope with the emergency of the URLLC service, so that the number of blind checks of the eMBB service users is increased, and the power consumption of the eMBB service users is increased.
In addition, there is also an uplink multiplexing method in the prior art, fig. 2 is a schematic diagram of multiplexing (non-overlapping) URLLC service and eMBB service between different uplink users in the prior art, as shown in fig. 2, in the uplink multiplexing method, a base station reserves some uplink time-frequency domain resources (i.e., the reserved resources shown in fig. 2, which can be used for URLLC data but cannot be used for eMBB data) for a URLLC service user, and then allocates the remaining uplink time-frequency domain resources to an eMBB service user. The URLLC service user can only use the reserved uplink time-frequency domain resources to send URLLC data, so these reserved uplink time-frequency domain resources can be referred to as URLLC time-frequency domain resources. And when the base station receives the URLLC service request, allocating the URLLC time-frequency domain resources to the URLLC service user. By the method, overlapping conflict between URLLC service users and eMB service users on uplink time-frequency domain resources can be avoided.
In the above method, the eMBB service user does not need to monitor the downlink control channel containing the uplink preemption information. However, due to the unpredictability and low delay limitation of the URLLC service, in the above method, more uplink time-frequency domain resources need to be reserved for the URLLC service user, which easily causes resource waste and results in a low resource utilization rate.

Detailed Description
In order to make the technical scheme and advantages of the invention more apparent, the invention is further described in detail with reference to the accompanying drawings and specific embodiments.
Fig. 3 is a flowchart of a method for indicating monitoring of uplink preemption information in an exemplary embodiment of the present invention. As shown in fig. 3, a method for indicating monitoring of uplink preemption information in an embodiment of the present invention includes the following steps:
and step 31, the base station reserves URLLC time-frequency domain resources for the uplink URLLC service in each time slot of the uplink frequency band, and allocates the reserved URLLC time-frequency domain resources to uplink eMBB service users.
In the technical scheme of the invention, the base station reserves URLLC time-frequency domain resources for the uplink URLLC service in each time slot of the uplink frequency band in consideration of the low delay requirement of the URLLC service, so that the reserved time-frequency domain resources are reserved in each symbol of each time slot as the URLLC time-frequency domain resources, and the low delay requirement of the URLLC service can be met. Therefore, the URLLC service user in the invention can transmit the URLLC data by using the reserved URLLC time-frequency domain resources.
In addition, after reserving the URLLC time-frequency domain resources, the base station also allocates the reserved URLLC time-frequency domain resources to the uplink eMBB service users, so that the reserved URLLC time-frequency domain resources are not only used for uplink URLLC service users, but also used for uplink eMBB service users, thereby effectively improving resource utilization rate and not causing resource waste.
In addition, in the technical solution of the present invention, the step 31 may be embodied in various ways. The technical solution of the present invention will be described in detail below by taking several specific implementation manners as examples.
For example, preferably, fig. 4 is a schematic diagram of URLLC time-frequency domain resources in the embodiment of the present invention, as shown in fig. 4, a preset number of subbands of each slot (slot) on an uplink frequency band may be used as reserved URLLC time-frequency domain resources, and the reserved URLLC time-frequency domain resources are allocated to uplink eMBB service users. Therefore, the reserved URLLC time-frequency domain resources shown in fig. 4 can be used for uplink eMBB service users as well as uplink URLLC service users.
In the technical solution of the present invention, the specific number of the subbands may be preset according to the needs of the actual application, and the specific value taking situation is not described herein any more.
In addition, preferably, in another embodiment of the present invention, the subbands used as reserved URLLC time-frequency domain resources in adjacent time slots are staggered with each other, so that preparation can be performed in advance for subsequent possible frequency hopping operations, so as to improve the overall performance of the system.
In addition, preferably, in another embodiment of the present invention, when the base station allocates the reserved URLLC time-frequency domain resource for the uplink eMBB service user, the capability of the eMBB service user to detect the PDCCH may also be considered.
Therefore, preferably, in another embodiment of the present invention, when the base station allocates the reserved URLLC time-frequency-domain resources to an eMBB service user, the current blind detection number of the eMBB service user in each time slot does not exceed (X-Y), where X is the maximum allowed blind detection number of each user in each time slot of the current subcarrier interval, and Y is the blind detection number that the eMBB service user needs to increase in each time slot in order to monitor the uplink preemption information.
For example, according to the relevant specifications of the 3GPP protocol, the maximum number of blind detections X allowed for each user in each slot is 44, 36, 22 and 20 for different subcarrier spacings (15KHz, 30KHz, 60KHz and 120 KHz). When the subcarrier spacing is 15KHz, X is 44; if the number of blind tests that a certain eMBB service user needs to increase in each timeslot for monitoring uplink preemption information is 8 (that is, Y is 8), when the base station allocates the reserved URLLC time-frequency domain resource to the eMBB service user, the number of blind tests of the eMBB service user in each timeslot cannot exceed 36.
Through the setting, the reserved URLLC time-frequency domain resources can be allocated to the eMBMS user on the premise of considering the capability of the eMBMS user for detecting the PDCCH, so that the eMBMS user can better utilize the allocated URLLC time-frequency domain resources.
In the technical scheme of the invention, if an eMB B service user uses reserved URLLC time-frequency domain resources to send eMB B data, the eMB B service user needs to monitor uplink preemption information so as to deal with the possible emergent situations of URLLC service; and if the eMB service user does not use the reserved URLLC time-frequency domain resource to send the eMB data, the eMB service user does not need to monitor the uplink preemption information, thereby reducing the blind check times and power consumption of the eMB service user.
Therefore, in the technical solution of the present invention, the base station may set a monitoring indication bit, and carry the monitoring indication bit in the downlink signaling to send to the eMBB service user, so as to inform the eMBB service user whether to need to monitor the uplink preemption information.
In addition, in the technical solution of the present invention, the step 32 may be embodied in various ways. The technical solution of the present invention will be described in detail below by taking several specific implementation manners as examples.
For example, in an embodiment of the present invention, the base station may add the monitoring indication bit in Downlink Control Information (DCI) to indicate whether the eMBB service user needs to monitor the uplink preemption information.
Of course, in the technical solution of the present invention, the base station may also add the monitoring indication bit in other downlink signaling to indicate whether the eMBB service user needs to monitor the uplink preemption information, which is not described herein again.
In addition, in the technical solution of the present invention, the monitoring indication bit may indicate whether the eMBB service user needs to monitor the uplink preemption information in a plurality of ways.
For example, in another embodiment of the present invention, when the value of the monitoring indication bit is 1, it indicates that an eMBB service user needs to monitor uplink preemption information; and when the value of the monitoring indication bit is 0, indicating that the eMBB service user does not need to monitor the uplink preemption information.
Of course, in the technical solution of the present invention, other value-taking manners may also be used in the monitoring indication bit to indicate whether the eMBB service user needs to monitor the uplink preemption information, which is not described herein again.
And step 33, before the eMB service user sends the eMB data, determining whether to monitor the uplink preemption information according to the monitoring indication bit.
For example, before an eMBB service user sends eMBB data, if a monitoring indication bit in a downlink signaling (e.g., DCI) received by the eMBB service user indicates that uplink preemption information needs to be monitored (e.g., the value of the monitoring indication bit is 1), the eMBB service user will always monitor the uplink preemption information before sending the eMBB data this time. And when the eMB data transmission is finished, the eMB service user does not monitor the uplink preemption information any more.
For another example, before the eMBB service user sends the eMBB data, if the monitoring indication bit in the downlink signaling (e.g., DCI) received by the eMBB service user indicates that the uplink preemption information does not need to be monitored (e.g., the value of the monitoring indication bit is 0), the eMBB service user does not monitor the uplink preemption information before sending the eMBB data, but directly sends the eMBB data.
Through the methods described in the above steps 31 to 33, the base station can reserve URLLC time-frequency domain resources for the uplink URLLC service in the uplink frequency band, and allocate the reserved URLLC time-frequency domain resources to the uplink eMBB service user. URLLC service users can only use reserved URLLC time-frequency domain resources, but eMBB service users can also use these reserved URLLC time-frequency domain resources. The base station can inform eMB B service users whether to monitor uplink preemption information or not through downlink signaling carrying monitoring indication bits, so that eMB B service users sending eMB B data by using reserved URLLC time-frequency domain resources are informed of the uplink preemption information to be monitored, and eMB service users not sending eMB data by using reserved URLLC time-frequency domain resources are informed of the uplink preemption information not to be monitored. Through the mode, not all eMB service users but only a part of eMB service users need to monitor the downlink control channel containing the uplink preemption information, so that the blind detection times and power consumption of the eMB service users in the whole system are greatly reduced, the resource utilization rate is effectively improved, and the frequency spectrum efficiency and the energy efficiency are considered.
