detailed description

The present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

Method embodiment one:

As shown in FIG. 1 , this embodiment provides a scheduling control method, where the method includes:

Step S100: The first type of node sends the indication information to the second type of node through the downlink channel.

The indication information includes configuration information of a scheduling request signaling SR resource of a second type of node.

The scheduling control method in this embodiment is applied to a first type of node, and the first type of node may be one of the following: a base station, a micro base station, a pico base station, a femto base station, a low power node, and a relay station;

The second type of node is a one or a group of terminals. The terminal here may be a second type node of human to human H2H, a second type of node of machine to machine M2M, a second type of node of vehicle to vehicle V2V or a second type of node of device to device D2D. A typical representative of the second type of nodes of the H2H may include a mobile phone or the like. The second type of nodes of the M2M are typically nodes capable of communication between machines. The second type of vehicle-to-vehicle node includes an in-vehicle communication node. The D2D node is a device-to-device communication node. D2D communication means that the terminal can directly communicate without going through the base station, and each D2D communication link occupies the same resources as one cellular communication link, which can improve resource utilization and network capacity. M2M is a research hotspot of the fifth mobile 5G communication, including not only direct communication between terminals, but also communication between various machines. The second type of node may specifically be a mobile phone or the like.

In this embodiment, the first type of node sends configuration information of the SR resource to the second type of node. The SR is an abbreviation of Scheduling Request, and corresponds to scheduling request signaling.

In the embodiment, the first type of node controls, by using the scheduling information of the SR resource, the first type of node to send the SR frequency, timing, and the like information, thereby implementing scheduling control, thereby implementing scheduling control. After the second type of node accesses the first type of node, the spurt requests the first type of node to apply for resource scheduling, resulting in scheduling congestion and the like.

The SR resource is divided into one or more SR sets according to at least one of the following divisions:

The type of the second type of node that sent the SR;

The working mode of the second type of node that sends the SR;

Trigger the type of service that sends the SR;

Triggers a combination of service types that send SRs.

The type of the second type of node may include a second node of the person to the person H2H; a second node of the machine to the machine M2M; a second node of the vehicle to the vehicle V2V; a second node of the device to the device D2D, and the like.

The working mode of the second type of node may include an enhanced working mode, a non-enhanced working mode, and a regular mode. The coverage enhancement mode is an operational mode capable of being connected to a cell employing coverage enhancement techniques. The non-coverage enhancement mode is capable of connecting to a working mode that does not employ overlay enhancement techniques. The normal mode may be a working mode that is configured by default in the second type of node, and the regular mode may be one of the enhanced coverage working mode and the non-enhanced coverage working mode, but the second type of node itself The distinguishing normal mode is the enhanced coverage mode of operation and the non-enhanced coverage mode of operation. Of course, according to the different indicators, the working mode of the second type of node has other ways of dividing.

The service type that triggers the sending of the SR is the SR that is sent by the second type of node to implement a certain service, and the service type that triggers the service of the second type of node to send the SR. The combination of the types of services includes a combination of one or more services.

The service type classification of the second node includes at least one of the following: classifying according to a data packet transmission rate; classifying according to a transmission delay of the data packet; classifying according to a packet transmission error rate; and classifying according to a packet length of the data packet; Classified according to the transmission period of the packet. The packet here A packet of service data is transmitted for a packet corresponding to various services.

The SR resources are divided into one or more SR sets in this embodiment. Multiple sets here refer to at least two SR sets.

The SR resources are divided into SR sets to facilitate more efficient management and control of the first type of nodes.

Different SR sets correspond to different physical random access channel PRACH resources. The PRACH resource may include a PRACH resource including a time-frequency resource of a PRACH and a random access sequence. The different PRACH resources corresponding to different SR sets may include: different time-frequency resources of the PRACH corresponding to different SR sets and/or different random access sequences corresponding to different SR sets.

In this case, the second type of nodes of different types, the second type of nodes of different working modes, the second type of nodes of different service types, or the second type of nodes of different service types are randomly selected by using PRACH resources corresponding to different sets of SRs. Access, to avoid the second type of node of the same type to apply for too many resource scheduling, resulting in other types of second type of node can not request scheduling.

The SR resources of the second type of node configuration belonging to the same SR set are different. In this case, each of the second type of nodes has different SR resources, and each of the second type of nodes uses the SR resources allocated thereto to send scheduling request signaling.

Of course, SR resources belonging to the same SR set can be randomly selected by the second type of nodes. That is, one or more SR resources are configured in one SR set, and belong to the second type of nodes in the same SR set, and the SR resources are randomly selected to send scheduling request signaling.

The scheduling priorities of the different SR sets are different. The scheduling priority is the priority of the SR information sent by the first type of node in response to the second type of node. Generally, the higher the scheduling priority, the faster the first type of node will respond to the SR information sent by the second type of node. The mapping relationship between the SR set and the scheduling priority may be configured by the first type of node, or may be configured by default by a communication standard; how is the mapping relationship between the SR set and the scheduling priority formed? Kind, not limited to the above two ways.

As shown in FIG. 2, in addition to the step S100, the method in this embodiment further includes:

Step S110: Determine, according to the SR resource used by the second type of node to send the SR information, the SR set to which the SR resource of the sent scheduling request signaling belongs;

Step S120: Determine a scheduling priority according to the SR set;

Step S130: Respond to the SR information according to the scheduling priority.

In step S110, the corresponding SR set is determined according to the SR resource that the second node sends the SR information, and the corresponding scheduling priority is determined according to the SR set, and the SR information is responded according to the scheduling priority, if the scheduling priority is performed. High, the first type of node will respond to the SR information more quickly, and if the scheduling priority is low, it is possible that the first type of node will likely respond to the SR information later.

In this case, the first type of node will respond to the SR information in sequence according to the scheduling priority, and may be able to preferentially respond to the SR information that needs to respond quickly, and the SR information that can respond relatively slowly will respond later. Obviously, this will make the first type of node more responsive to the SR information, and reduce the phenomenon that the user's usage satisfaction is poor due to the disorder of the response.

The length of the SR response time window corresponding to the different scheduling priorities is different. The higher the priority is, the shorter the SR response time window is. The step S130 may include: in the SR response time window corresponding to the scheduling priority, Sending confirmation information to the second type of node that sends the SR information; the confirmation information is used to notify the second type of node to successfully receive the SR information. The acknowledgment information may include a hybrid automatic repeat request response HARQ-ACK.

The method further includes:

Step S140: Send scheduling information that responds to the SR information to the second type of node.

The scheduling information includes various information such as scheduling parameters, where the confirmation information is that the first type of node sends a second type of node, and the second type of node is notified that the first type of node has received the SR information, and the scheduling is performed. The information is scheduling information formed by performing resource scheduling in response to the SR information. Pass The scheduling information and the acknowledgment information may all be used as response messages in response to the SR information, and should be transmitted within a specified time corresponding to the scheduling priority.

The acknowledgment information and the scheduling information are sent in different signaling. After the acknowledgment information and the scheduling information are sent in different signaling, the first type of node may first send the acknowledgment information to notify the second class after receiving the SR information and before completing the resource scheduling to form the scheduling information. The node has received the SR information to avoid repeated transmission of the SR information of the second type of node.

The step S140 may include: after the sending the confirmation information, sending the scheduling information.

The step S140 may specifically include: determining, according to the scheduling priority, sending a sending delay between the acknowledgment information and the scheduling information; after transmitting the acknowledgment information, sending the sending after the sending delay Scheduling information.

For example, both the acknowledgement information and the scheduling information need to be sent in the SR response time window. If the acknowledgement information is sent first, it may be determined according to the SR response time window and the sending time of the acknowledgement information. The acknowledgment information must be sent after the acknowledgment information is sent, and the allowable time interval between the acknowledgment information and the scheduling information is the maximum value of the transmission delay. Finally, the first type of node needs to send the scheduling information in the sending delay, and perform the response of the SR information and the resource scheduling in time to avoid the re-requesting access of the second type of node and the sending of the SR information. Into the phenomenon of congestion.

The method further includes:

Sending delay information including the transmission delay to the second type of node. In the embodiment, the first type of node directly informs the second type of node by using the delay information, so that the second type of node knows the after receiving the delay information. The transmission delay will receive the scheduling information after the transmission delay.

Transmitting the delay information including the sending delay to the second type of node, including:

Combining the delay information with the acknowledgement information to form joint coding information;

Transmitting the joint coding information to the second type of node.

In the embodiment, the acknowledgment information and the delay information are jointly encoded, so that the signaling overhead of the interaction between the first type node and the second type node can be reduced, and the joint coding information can be sent once. Sending the confirmation information and the delay information reduces the amount of information interaction between the first type of node and the second type of node, and reduces the power consumption of the second type of node.

The joint coding here, for example, uses two 2 bits to indicate acknowledgment information, the two bits "00" indicate that no SR information is received; "01" indicates the acknowledgment information, and the transmission delay is one quantization unit; "10" indicates the confirmation information, and the transmission delay is 2 quantization units; "11" indicates the confirmation information, and the transmission delay is 3 quantization units.

As shown in FIG. 3, the step S140 may further include:

Step S141: After transmitting the acknowledgement information, send first scheduling information within the sending delay; the first scheduling information includes a scheduled scheduling moment;

Step S142: When the scheduled scheduling time is reached, the second scheduling information is sent.

In the embodiment, the scheduling information may include first scheduling information and second scheduling information. When the first type of node is currently busy and cannot perform resource scheduling immediately, the SR information must be responded to in the SR response time window to complete the response of the SR information. In this case, the load of the first type of node is further intensified. The first type of node will first send the first scheduling information within the SR response time window. A reservation scheduling time is included in the first scheduling information. In this way, after the second type of node receives the first scheduling information, it knows that it is received at the scheduled scheduling time to receive the second scheduling information. After the first type of node determines the scheduled scheduling time according to its own load and the like, the second scheduling information will be sent at the scheduled scheduling moment. In this way, the second type of node can successfully receive the second scheduling information at the scheduled scheduling time, and the second scheduling information includes parameters of resource scheduling, etc., so that the response to the SR information is completed.

In the embodiment, when the acknowledgement information is sent, the acknowledgement information may be separately sent to each second type of node, or the acknowledgement information sent to the multiple second type of nodes may be carried in The same message is sent to the second type of node. For example, by using information aggregation, the acknowledgment information of multiple second-type nodes is aggregated and sent in the same message, thus reducing the number of times the first-type node information is sent.

This embodiment provides a scheduling control method, which implements scheduling control of a second type of node by including configuration information of an SR resource, thereby avoiding congestion.

Method Embodiment 2:

As shown in FIG. 4, this embodiment provides a scheduling control method, where the method includes:

Step S210: Receive indication information sent by the first type of node, where the indication information includes configuration information of a scheduling request signaling SR resource of the second type of node;

Step S220: Send SR information according to the configuration information of the SR resource.

The scheduling control method in this embodiment can be applied to a second type of node, and the second type of node can be a terminal, such as an M2M terminal, an H2H terminal, a V2V terminal, a D2D terminal, or the like.

The second type of node in step S210 in this embodiment will receive the indication information. The indication information may include configuration information of the SR resource, and the SR information is sent on the corresponding SR resource, so that at least the control of sending the SR information by the second type of node is implemented, thereby implementing access to the second type of node. The scheduling control of the first type of node and the control of the resource scheduling request.

As shown in FIG. 5, the step S220 may include:

Step S221: Determine, according to configuration information of the SR resource, an SR set to which the second type of node belongs;

Step S222: Determine an SR resource according to the SR set.

Step S223: Send SR information by using the SR resource.

In the embodiment, the step S220 includes: determining the SR set of the second type of node, and determining the SR resource configured in the SR set, and transmitting by using the SR resource in the SR set. The SR information is not the SR resource that is difficult to use and the SR information is transmitted. Obviously, the transmission control of the second type of node SR information is realized.

The step S222 can include:

An SR resource configured to the second type of node from the set of SRs.

Since each of the second type of nodes in the SR set is configured with its corresponding SR resource, at this time, after determining the SR set, the SR resource corresponding to the second type of node is found in the corresponding SR set to send the SR information.

Of course, in another example, the SR resources in the SR set may not be separately configured to each second type node, but one or more SR resources are configured to belong to the second class in the SR set. If the node is shared, the step S222 may include: randomly selecting an SR resource for sending the SR information from the SR resources corresponding to the SR set.

Further improved as this embodiment,

As shown in FIG. 6, the method further includes:

Step S230: Determine a response priority according to the SR set;

Step S240: Determine an SR response time window length according to the response priority level;

Step S250: Receive, in the length of the SR response time, a message that the first type of node responds to the SR information;

Step S260: If the message responding to the SR information is received within the length of the SR response time, it is confirmed that the first type of node successfully receives the SR information.

In the embodiment, the second type of node further determines a response priority according to the set of SRs. Generally, the higher the priority of the response, the faster the first type of node responds to the SR information. In the embodiment, the second type of node can predict, according to the length of the SR response time, that information corresponding to the SR information sent by the first type of node is received, so as to maintain the awake state. In this embodiment, the second type of node will receive and detect information of the first type of node in response to the SR information within the length of the SR response time, and receive the SR response in response to receiving the first type of node. After the information of the information, the SR information that has been successfully sent to the first type of node is considered to be at least not retransmitted at the present time to cause re-reception of the first type of node.

The step S250 may include:

Receiving confirmation information in response to the SR information;

After receiving the acknowledgement information, the second type of node enters a dormant state or an idle state;

And according to the length of the SR response time, the second type of node wakes up to receive the scheduling information that responds to the SR information at a sending moment of scheduling information.

The information responsive to the SR information may include confirmation information and scheduling information. In this embodiment, in order to further save power consumption of the second type of node, after the second type of node receives the acknowledgement information, it will enter a sleep state of idle power or an idle state. In the sleep state or the idle state, the second type of node does not need to blindly check the downlink channel, thereby saving power consumption. The scheduling information herein includes resource information of resources allocated by the first type of node in response to the SR information sent by the second type of node.

In a specific implementation, the second type of node further receives delay information from the first type of node, where the delay information includes a sending delay, where the sending delay indicates that the scheduling information is in the acknowledgement How long after the information transmission time is sent. The second type of node will receive the scheduling information after the sending delay according to the sending delay. In addition, the scheduling information and the delay information may be carried in joint coding information formed by joint coding, and the second type of node may receive the joint coding information, decode the joint coding information, and obtain the Confirmation information and the transmission delay.

The second type of node may determine the arrival time of the scheduling information according to the receiving moment of the acknowledgement information and the SR response time window, so the second type of node will predict the arrival of the scheduling information.
