Detailed Description
The present disclosure now will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the disclosure are shown. The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
Fig. 1 is a flowchart illustrating a time domain resource scheduling method according to an embodiment of the present disclosure, as shown in fig. 1:
And 103, the terminal receives the time domain configuration scheduling information sent by the base station for performing time domain resource scheduling. When the terminal has downlink service data, the base station determines time domain configuration scheduling information corresponding to the terminal according to the buffer load, the preset algorithm and the resource suggestion auxiliary information. The preset algorithm may be any of a variety of existing algorithms.
The time domain resource Scheduling method in the embodiment solves the problem that a time domain resource Scheduling decision is not matched with an actual service type when the existing 5G NR network side simultaneously supports the Same-slot Scheduling (k 0= 0) and Cross-slot Scheduling (k 0> 0); the terminal reports auxiliary information (resource suggestion auxiliary information) which accords with the service type and is used for scheduling the time domain resource scheduling suggestion to a network side (base station), and the network side integrates the existing algorithm and the terminal auxiliary information to perform scheduling decision, so that the scheduling decision is matched with the service type as much as possible, and service delay increase and terminal power consumption increase caused by the fact that the scheduling is not matched with the service delay requirement can be reduced.
Before the terminal sends the resource suggestion auxiliary information corresponding to the service delay requirement to the base station, the terminal establishes RRC connection with the base station or completes RRC reconfiguration, and then receives a time domain configuration list issued by the base station. The time domain configuration list includes: multiple lines of time domain resource configuration information; each line of time domain resource configuration information is provided with a line index number, and the time domain resource configuration information comprises a value of k0; k0 is a parameter in the 3GPP protocol for identifying the time relationship of scheduling and data transmission.
A time domain configuration item is provided with a k0 value (a time sequence from a Physical Downlink Control Channel (PDCCH) to a Physical Downlink Shared Channel (PDSCH)), and when k0=0 (home-slot Scheduling), the time delay is minimum, so that the time domain configuration item is suitable for services with high real-time requirements; when k0 is greater than 0 (Cross-slot Scheduling), the method is favorable for saving power of the terminal and is suitable for non-real-time services with sparse flow.
As shown in fig. 2, after the terminal establishes RRC connection with the base station or completes RRC reconfiguration, the relevant configuration of time domain resource allocation is completed, the time domain configuration list includes multiple rows of configuration information, each row of configuration information is provided with its own index number, and the index number of the row is used in subsequent DCI scheduling. The configuration information of each row contains the value of k0, and according to a formula, k0 determines the number of slot intervals from the scheduling slot of the subsequent PDCCH DCI to the starting slot of the PDSCH.
The time domain configuration scheduling information includes: a row index number of the time domain configuration list; a terminal receives DCI sent by a base station; and the DCI carries a row index number, the terminal acquires time domain resource configuration information from the time domain configuration list according to the row index number, calculates a slot based on the time domain resource configuration information, and receives data on the slot.
As shown in fig. 2, the base station carries the row index number used in the current scheduling in the time domain resource allocation indication of the DCI; and the terminal calculates the starting position of the PDSCH slot and obtains the starting symbol position and the length of the received data by looking up the table according to the row index number indicated by the DCI and by using the k0 value and other time domain configuration information in the configuration row of the corresponding time domain configuration list, and starts to receive the service data at the corresponding position of the PDSCH.
The terminal sends resource suggestion auxiliary information to the base station through the information of the RRC layer; wherein the message comprises: UEAssistanceInformation message. The terminal adds a powerPrefIndication-r11 attribute in a UEAssociation information message and configures an attribute value of the powerPrefIndication-r11 attribute; the attribute values are used to characterize k0 corresponding to traffic delay requirements. The attribute values include: lowpowerconstumtion and normal.
In the prior art, a network side can only rely on factors such as cell or buffer load, channel quality and the like in a current short time to decide a row index of time domain configuration, and because the network side cannot accurately predict the subsequent flow characteristics and time delay requirements of the service, the time domain scheduling decision is not necessarily optimal. For example, when the service needs low delay but the scheduling uses k0>0 (usually taking a value of 1), the service delay is increased, and when the service is not sensitive to the delay but the scheduling uses k0=0, the terminal is not powered on.
The terminal and the base station complete the related configuration of RRC time domain resource allocation, as shown in fig. 2, the terminal reports the suggested value auxiliary information meeting the service delay requirement to the network side through the UEAssistanceInformation message of the RRC layer according to the type of the current service operated by the terminal. For the NSA mode, the existing powerPrefIndication-r11 attribute is used, the attribute comprises two values of lowPowerConsumption and normal, the lowPowerConsumption indicates that the terminal suggests that the network uses the configuration with optimized power consumption, namely k0>0 (usually, the value is 1), and the normal indicates that the terminal suggests that the network uses the normal configuration, namely k0=0. For the SA mode, the powerPrefIndication-r11 attribute can be extended and reused in the nonCriticalExtension attribute in the UEAsistanceInformation message.
When downlink service data exist, the base station makes a scheduling decision of which line of time domain configuration items to use according to the load of the current buffer area, a self scheduling algorithm and resource suggestion auxiliary information sent by the terminal; and the base station carries the row index number used by the scheduling in the time domain resource allocation indication of the DCI. And the terminal calculates and receives data on the designated slot according to the row index number indicated by the DCI. Based on UEAssociation information of an RRC layer, resource suggestion auxiliary information meeting the current service delay requirement is provided for a network, a base station does not make time domain scheduling decision unilaterally according to self information any more, and suggestion information of a terminal side is synthesized, so that scheduling is more accurately matched with the service delay requirement.
As shown in fig. 3, after the 5G terminal opens the APP, the terminal determines whether the APP belongs to a real-time application or a non-real-time application according to the application type. After the terminal and the network complete RRC link establishment or RRC reconfiguration, the terminal sends resource suggestion auxiliary information meeting the service delay requirement to the 5G network, the 5G network requests a service platform and obtains service data, then scheduling decisions of downlink time domain resources are made by combining suggestion values in the resource suggestion auxiliary information and self algorithms, corresponding row index values are issued through DCI, and the terminal starts to receive the service data at the appointed position of a PDSCH channel according to DCI instructions.
The UEAssistant information message of the RRC layer is used for the terminal to report various auxiliary information to the network, and the powerPrefIndication-r11 attribute of the message comprises two power consumption configuration suggested values which correspond to the value of the time domain k0 and are directly used in the NSA mode; the NR version of the message can be realized by extending and reusing the attribute of powerPrefIndication-r11 in the existing noncriticalExtension attribute, and the attribute of powerPrefIndication-r11 is added in the UEAsistingInformation message. The UEAssistant information is auxiliary information, does not influence the existing scheduling process, plays an optimization role in the scheduling decision of a network side, can be supported only by upgrading the software of the terminal and the base station, and does not need to change hardware.
