Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a resource scheduling method, network equipment, device and storage medium. Background Art

[0002] New Radio (NR) introduces grant-free scheduling, which includes two types: Configured Grant Type 1 and Configured Grant Type 2. The advantage of grant-free scheduling is that there is no need to obtain authorization, and the allocated resources can be directly used for uplink scheduling.

[0003] Configuration Grant Type 1 configures grant-free scheduling periodic resources through Radio Resource Control (RRC) signaling, and the terminal does not need dynamic grant (Grant) to use these resources to send uplink services. Configuration Grant Type 2 configures some parameters of the periodic resources of the grant-free scheduling through RRC signaling, but it is also necessary to indicate the activation and deactivation of the uplink grant-free through downlink control information (DCI), and allocate resource parameters to the terminal in the same activated DCI.

[0004] However, when the number of access terminals increases to a certain extent, downlink control resources are very tight, and configuring the activation and deactivation of grant type 2 will consume most of the control resources to send DCI. At the same time, most of the uplink frequency domain resources are used for grant-free scheduling. Before DCI releases the resources, these resources cannot be used again, but the actual terminals do not necessarily use these resources, resulting in unnecessary DCI signaling overhead and resource waste.

[0047] The scheduling-free authorization of the NR system is configured with two authorization modes: configuration authorization type 1 and configuration authorization type 2. The advantage of scheduling-free is that there is no need to obtain authorization, and the allocated resources can be directly used for uplink scheduling.

[0048] Among them, configuration authorization type 1 configures scheduling-free period resources through Radio Resource Control (RRC) signaling, and the terminal can use this part of resources to send uplink services without dynamic authorization (Grant).

[0049] Among them, configuring authorization type 2 configures part of the parameters of the scheduling-free periodic resources through RRC signaling, but it cannot be used at this time. It is necessary to control the activation and deactivation of the scheduling-free resources through DCI in the future. At the same time, frequency domain resource parameters are allocated to the terminal in the same activated DCI. The terminal can use this part of the resources to send uplink services without dynamic authorization. Figure 1 This is a flowchart of scheduling-free resource activation and deactivation provided by related technologies, such as Figure 1 As shown, in configuration authorization type 2, the base station determines whether to use resources for free scheduling or dynamic scheduling by judging the activation process.

[0050] When free scheduling is not configured, dynamic scheduling is used and the terminal can use uplink resources only after receiving dynamic authorization.

[0051] The uplink service is the Physical Uplink Shared Channel (PUSCH), and the uplink resources are the number of Physical Resource Blocks (PRBs) occupied in the PUSCH, while the number of PRBs in the bandwidth is limited. DCI is a control instruction sent to the terminal through the Physical Downlink Control Channel (PDCCH). DCI consists of Control Channel Elements (CCE), which also occupies the PRBs in the downlink bandwidth. The number of DCIs that can be sent in the bandwidth is limited.

[0052] When grant type 2 is configured, there is unnecessary DCI signaling overhead and resource waste. On the one hand, if the scheduling-free resources allocated to the terminal are not used, they need to be released (i.e., deactivated) to release the resources, and deactivation is controlled by DCI. When the number of access terminals increases to a certain extent, the downlink control resources are very tight. At this time, the activation and deactivation of grant type 2 will consume most of the control resources to send DCI. In addition, whether the terminal has uplink services is random, and repeated activation and deactivation of resources requires consumption of DCI to control.

[0053] On the other hand, since frequency domain resources are allocated to the terminal in advance, these resources cannot be used until they are released through DCI. Most of the uplink frequency domain resources are used for scheduling-free authorization. The resources used for scheduling-free authorization are not necessarily used by the terminal. When the number of users is large, it will affect other users with business needs.

[0054] In response to the above-mentioned problems existing in the related technology, the embodiments of the present application provide a resource scheduling method, network equipment, apparatus and storage medium. When the network side issues a DCI for activating the configuration authorization type 2, a timer with a time range associated with the period of the non-scheduling resources is started. When the timer times out, the non-scheduling resources are scheduled as inactive resources, thereby effectively improving the uplink spectrum resource utilization rate and reducing the DCI activation and deactivation to save the DCI signaling overhead.

[0060] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0061] Figure 2 is one of the flow charts of the resource scheduling method provided in the embodiment of the present application, such as Figure 2As shown, the execution subject of the method is a network device, such as a base station, etc. The method includes at least the following steps:

[0062] Step 201: When a DCI for activating configuration grant type 2 is issued, start a timer;

[0063] Step 202: When the timer times out, determine that the scheduling-free resource is an inactive resource, and schedule the inactive resource;

[0064] The time range of the timer is associated with the period of the scheduling-free resources, and the scheduling-free resources include resources of configuration authorization type 2 allocated to the scheduling-free terminal.

[0065] Specifically, for the resource configured with authorization type 2 allocated by the network side to the terminal, for the convenience of explanation, the resource is described as a scheduling-free resource and the terminal is a scheduling-free terminal. The network side temporarily defines the scheduling-free resource as an inactive resource by maintaining a timer. Within a certain period of time, the inactive resource part can be used for non-scheduling-free, such as dynamic scheduling.

[0066] Add a timer on the network side and configure related parameters of the timer.

[0067] When the timer times out, the network side will schedule the unscheduled resources as inactive resources.

[0068] The resource scheduling method provided in the embodiment of the present application starts a timer whose time range is associated with the period of the non-scheduling resources when the network side issues the DCI for activating the configuration authorization type 2. After the timer times out, the non-scheduling resources are scheduled as inactive resources, thereby effectively improving the uplink spectrum resource utilization rate and reducing DCI activation and deactivation to save DCI signaling overhead.

[0069] Optionally, the relevant parameters of the timer mainly refer to the time parameters. The time parameters may include the start time of the timer, the time range of the timer, etc. When the network side issues the DCI for activating the configuration authorization type 2, the timer is started. The time range of the timer can be any one of the cycle times of 5ms, 10ms, 20ms, and 40ms, which is associated with the cycle of the scheduling-free resource, and the network side is configured according to the cycle of the scheduling-free resource at that time.

[0070] In some embodiments, scheduling the inactive resources in step 202 includes:

[0071] Allocate some inactive resources to other terminals except the scheduling-exempt terminals for dynamic scheduling.

[0072] Specifically, after the timer times out, the scheduling-free resources are regarded as inactive resources for scheduling, which may include: allocating some inactive resources to other terminals except the scheduling-free terminals for dynamic scheduling. For ease of description, the terminals except the scheduling-free terminals are referred to as other terminals in the following text.

[0073] During the inactive period of the scheduling-free resources, since the scheduling-free terminals themselves may still need to use the scheduling-free resources, even if the scheduling-free resources are regarded as inactive resources within a certain period, all the scheduling-free resources cannot be allocated to other terminals for use.

[0074] Optionally, it further includes: not allocating the inactive resources to other terminals except the scheduling-free terminal for dynamic scheduling. Of course, even if the scheduling-free resources are in an inactive period, the network side may choose not to allocate the scheduling-free resources to other terminals for use.

[0075] The resource scheduling method provided in the embodiment of the present application, after treating the non-scheduling resources as inactive resources, the network side can allocate some of the inactive resources to other terminals except the non-scheduling terminals for dynamic scheduling, thereby effectively improving the uplink spectrum resource utilization rate, and at the same time reducing DCI activation and deactivation to save DCI signaling overhead.

[0076] In some embodiments, allocating some inactive resources to other terminals except the scheduling-exempt terminal for dynamic scheduling includes:

[0077] If no uplink valid data sent by the scheduling-free terminal is received in the inactive resources, part of the inactive resources will be allocated to other terminals except the scheduling-free terminal for dynamic scheduling.

[0078] Specifically, it does not mean that as long as the scheduling-free resources are regarded as inactive resources, part of the inactive resources can be allocated to other terminals for dynamic scheduling. There is no necessity between the two.

[0079] If the network device does not receive uplink valid data sent by the scheduling-free terminal in the inactive resources, part of the inactive resources may be allocated to other terminals except the scheduling-free terminal for dynamic scheduling.

[0080] Uplink data refers to all data sent from the terminal to the network side in the communication system, including uplink valid data and control information related to data transmission, protocol header, etc. Uplink valid data refers to data with valid information sent by the network to the network side. In short, uplink valid data is the part of uplink data that has practical meaning and value.

[0081] During the inactive period of the scheduling-free resources, if the network side does not receive the uplink valid data sent by the scheduling-free terminal, it means that the scheduling-free terminal is not actually using the scheduling-free resources temporarily. Therefore, some inactive scheduling-free resources can be allocated to other terminals for dynamic scheduling to improve the utilization rate of the uplink spectrum resources.

[0082] In some embodiments, each inactive resource is composed of a first physical resource block and a second physical resource block, and the number of the first physical resource blocks is predetermined;

[0083] Allocate some inactive resources to other terminals except the terminals exempted from scheduling for dynamic scheduling, including:

[0084] The second physical resource block is allocated to other terminals except the scheduling-exempt terminal for dynamic scheduling.

[0085] Specifically, based on whether it can be allocated to other terminals for scheduling, the physical resource blocks (PRBs) in the inactive resources are divided into first PRBs and second PRBs, where the first PRBs refer to PRBs reserved for scheduling-free, and the second PRBs refer to PRBs that can be allocated to other terminals for dynamic scheduling.

[0086] The significance of distinguishing inactive resources is that even if the non-scheduled resources can be partially allocated to other terminals, it cannot affect the resource usage requirements of the non-scheduled terminals themselves. Therefore, the first PRB needs to be reserved to monitor the resource usage requirements of the non-scheduled terminals.

[0087] In some embodiments, the resource scheduling method further includes:

[0088] The received power of the first physical resource block is detected, and based on the detection result, it is determined whether the scheduling-free terminal uses the scheduling-free resources.

[0089] Specifically, the network side detects the receiving power of the first PRB reserved for each inactive scheduling-free resource to determine whether the scheduling-free terminal uses the scheduling-free resource. The receiving power refers to the signal power received by the network side when receiving the uplink data signal from the scheduling-free terminal, which can be used to evaluate the network side's receiving capability and performance of the uplink data signal from the scheduling-free terminal. A higher receiving power means that the network side can better receive the signal from the scheduling-free terminal, thereby increasing the probability of receiving valid uplink data.

[0090] Figure 3 This is the second flow chart of the resource scheduling method provided in the embodiment of the present application, such as Figure 3 As shown, the method comprises at least the following steps:

[0091] Step 301: When a DCI for activating configuration grant type 2 is issued, start a timer;

[0092] Step 302: When the timer times out, determine that the scheduling-free resource is an inactive resource, and allocate the second PRB to other terminals except the scheduling-free terminal for dynamic scheduling;

[0093] Step 303: Detect the received power of the first PRB, and determine whether the scheduling-free terminal uses the scheduling-free resources based on the detection result.

[0094] Optionally, if the scheduling-free terminal uses the scheduling-free resources, it is no longer appropriate to continue to allocate the scheduling-free resources to other terminals for dynamic scheduling; if the scheduling-free terminal does not use the scheduling-free resources, the scheduling-free resources can continue to be allocated to other terminals.

[0095] When the scheduling-free resource is inactive, the network side needs to continuously monitor whether the scheduling-free terminal uses the scheduling-free resource. The significance of reserving the first PRB is that the network side can detect the received power of the first PRB separately and determine whether the scheduling-free terminal uses the first PRB based on the detection result.

[0096] Optionally, the first PRB includes at least 4 PRBs. That is, when the scheduling-free resources are inactive, the network side allocates part of the inactive resources to other terminals for dynamic scheduling, and at least 4 PRBs are reserved for each inactive scheduling-free resource, and these 4 PRBs are not used for dynamic scheduling.

[0097] The resource scheduling method provided in the embodiment of the present application is that the network side allocates the second PRB of each scheduling-free resource to other terminals for dynamic scheduling when the scheduling-free resource is in an inactive period, and reserves the first PRB not for dynamic scheduling. By detecting the receiving power of the first PRB, it is determined whether the scheduling-free terminal uses the scheduling-free resource, thereby improving the utilization rate of uplink spectrum resources and saving DCI signaling overhead, while ensuring the original scheduling-free process of the scheduling-free terminal.

[0098] In some embodiments, when it is determined that the scheduling-free terminal uses scheduling-free resources, uplink valid data sent by the scheduling-free terminal and received on the first physical resource block is processed.

[0099] Specifically, the network side determines that the scheduling-free terminal uses the scheduling-free resources by detecting the receiving power of the first PRB, and needs to process the uplink valid data sent by the scheduling-free terminal and received on the first PRB.

[0100] The first PRB can support the scheduling-free terminal to perform scheduling-free during the current scheduling period. If the second PRB of each scheduling-free resource is allocated to other terminals for dynamic scheduling during the inactive period of the scheduling-free resource, the uplink valid data sent by the scheduling-free terminal received on the first PRB still needs to be processed. Optionally, if the received power on the first PRB is detected, but the cyclic redundancy check (CRC) result is a decoding error, it still relies on the existing scheduling-free retransmission to confirm that the packet data is not lost.

[0101] The resource scheduling method provided in the embodiment of the present application supports the normal scheduling-free process and scheduling-free retransmission of the scheduling-free terminal through the first PRB, thereby ensuring the normal transmission of data of the scheduling-free process of the scheduling-free terminal itself.

[0102] In some embodiments, the resource scheduling method further includes:

[0103] When receiving uplink valid data sent by the scheduling-free terminal, or detecting the received power in the target resource, the inactive resource is released in the next scheduling-free period and the timer is restarted;

[0104] Wherein, when the inactive resources are not allocated to other terminals except the scheduling-exempt terminals for dynamic scheduling, the target resources are inactive resources; or,

[0105] In the case where some inactive resources are allocated to other terminals except the scheduling-exempt terminals for dynamic scheduling, the target resources are the resources except some inactive resources in the inactive resources.

[0106] Specifically, if the network side receives valid uplink data sent by the unscheduled terminal during the inactive period of the unscheduled resources, or detects the receiving power within the target resources, it means that the unscheduled terminal has used the allocated uplink resources. The network side needs to release the inactive resources and restart the timer when the next unscheduled period arrives.

[0107] Regarding the case where the network side allocates part of the inactive resources to other terminals for dynamic scheduling and does not allocate the inactive resources to other terminals for dynamic scheduling, the target resources include different contents in these two cases.

[0108] Optionally, in the case where the network side allocates some inactive resources to other terminals for dynamic scheduling, the target resources refer to some inactive resources that are not allocated to other terminals, such as the first PRB in each of the aforementioned non-scheduled resources. That is, if the received power is detected on the first PRB, it is necessary to release the inactive resources in the next non-scheduled period and restart the timer.

[0109] Figure 4 This is the third flow chart of the resource scheduling method provided in the embodiment of the present application, such as Figure 4 As shown, the method comprises at least the following steps:

[0110] Step 401: When a DCI for activating configuration grant type 2 is issued, start a timer;

[0111] Step 402: When the timer times out, determine that the scheduling-free resource is an inactive resource, and allocate the second PRB to other terminals except the scheduling-free terminal for dynamic scheduling;

[0112] Step 403: Detect the received power of the first PRB, and determine whether the scheduling-free terminal uses the scheduling-free resources based on the detection result.

[0113] Step 404: When uplink valid data sent by the scheduling-free terminal is received, or when received power is detected on the first PRB, the inactive resources are released in the next scheduling-free period and the timer is restarted.

[0114] Optionally, in the case where the network does not allocate inactive resources to other terminals for dynamic scheduling, as long as the network detects the received power in the entire inactive resource, it indicates that the scheduling-free terminal uses the scheduling-free resource, and it is necessary to release the inactive resource in the next scheduling-free period and restart the timer. Optionally, if the received power is detected in the target resource, but the data has a CRC decoding error, the network side also needs to notify the scheduling-free terminal to perform scheduling-free retransmission.

[0115] Optionally, the scheduling-free terminal is not aware of the process of releasing the inactive resources. If the scheduling-free terminal has uplink data services to send, it still sends the uplink data on the allocated scheduling-free resources according to the scheduling-free process.

[0116] The resource scheduling method provided in the embodiment of the present application relies on the detection of the receiving power of the target resource on the network side to realize the switching of the active and inactive states of the scheduling-free resources, thereby ensuring the resource usage requirements of the scheduling-free terminal itself and improving the utilization rate of the uplink spectrum resources.

[0117] The technical solution provided in this application is further explained below through specific examples.

[0118] Example 1:

[0119] Figure 5 This is a fourth flow chart of the resource scheduling method provided in the embodiment of the present application, such as Figure 5 As shown, the inactive processing process of configuring the authorization type 2 scheduling-free resources based on the timer on the network side (base station) is shown, which specifically includes:

[0120] Step 1: The terminal scheduling-free activation timer is started. When downlink control information DCI for activating configuration grant type 2 is issued, the timer is started.

[0121] Step 2-1: The terminal sends uplink data. Optionally, after starting the timer, the resource scheduling method further includes:

[0122] Perform activation detection on uplink data sent by scheduling-free terminals;

[0123] If the activation detection passes and the data cyclic redundancy code check passes, the timer is restarted;

[0124] If the activation detection is continuously not passed within the time range of the timer, it is determined that the timer has timed out.

[0125] Specifically, after the timer is started, the network side needs to continuously perform activation detection on the uplink data signal sent by the scheduling-free terminal within the range of scheduling-free resources, so as to determine whether the current uplink data signal needs to be allocated to the terminal resources by the network side, so as to effectively perform resource scheduling and management.

[0126] After the network side receives the uplink data signal sent by the scheduling-free terminal, it performs activation detection. The purpose of activation detection is to ensure that the uplink data signal is correctly received and to perform resource scheduling according to the activation information. Whether the activation detection is passed depends on the relationship between the currently detected uplink receive power and the given threshold. If it exceeds the given threshold, the activation detection is passed.

[0127] After the activation test passes, a CRC check is required. If the activation test passes and the CRC check passes, it indicates that the scheduling-free terminal uses the scheduling-free resources, and the timer is restarted. Only when the activation test passes and the CRC check passes can it be considered as valid uplink data. However, generally speaking, the activation test will also pass the CRC check. Only in very rare cases will the activation test pass but the CRC check fail. If the CRC check fails, the original retransmission process of scheduling-free will be used.

[0128] If the activation detection fails, it indicates that the scheduling-free terminal has not used the scheduling-free resources temporarily. If the activation detection continues to fail within the time range of the timer, it indicates that the scheduling-free terminal has not used the scheduling-free resources within the time range of the timer. Therefore, there is a possibility that the scheduling-free resources can be treated as inactive or even allocated to other terminals for dynamic scheduling.

[0129] Optionally, during the period when the scheduling-free resource is in an inactive state, the scheduling-free terminal is not aware of it.

[0130] Step 2-2: The timer times out and the scheduling-free resource is determined to be an inactive resource.

[0131] Example 2:

[0132] Figure 6 This is a fifth flow chart of the resource scheduling method provided in the embodiment of the present application, such as Figure 6 As shown, the process of processing uplink services on the network side during the period when the scheduling-free resources are in an inactive state is shown, specifically including:

[0133] Step 1: Determine that the scheduling-free resources are inactive.

[0134] Step 2: The base station detects the signal quality to determine whether to use part of the scheduling-free resources for dynamic scheduling of other terminals.

[0135] Step 3-1: If the base station uses part of the scheduling-free resources for dynamic scheduling of other terminals, the other terminals use the part of the scheduling-free resources.

[0136] Step 3-2: If the base station does not use the scheduling-free resources for dynamic scheduling of other terminals, the base station needs to continuously monitor whether the scheduling-free resources are used by the scheduling-free terminals. If the scheduling-free terminals use the scheduling-free resources, the uplink valid data needs to be processed normally.

[0137] Example 3:

[0138] Figure 7 This is the sixth flow chart of the resource scheduling method provided in the embodiment of the present application, such as Figure 7 FIG. 4 shows a process of understanding inactive resources, which specifically includes:

[0139] Step 1: Determine whether the scheduling-free resource is used for dynamic scheduling.

[0140] Step 2-1: If the scheduling-free resources are not used for dynamic scheduling, the base station detects the received power in the entire scheduling-free resources.

[0141] Step 2-2: If some scheduling-free resources are used for dynamic scheduling, the base station detects the receiving power of the first PRB.

[0142] Step 3: If the base station detects the received power of the target resource, the target resource is the entire scheduling-free resource in step 2-1 and is the first PRB in step 2-2.

[0143] Step 4: If the base station detects the received power within the target resource, indicating that the scheduling-free terminal uses the scheduling-free resource, the inactive state is released in the next scheduling-free period and the timer is restarted.

[0144] Step 5: If a CRC decoding error occurs, the base station notifies the terminal to perform a scheduling-free retransmission.
