The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In a half-duplex FDD system, a network-side device such as a base station can also transmit data to other UEs while receiving data transmitted by the UE. When the network side device is in the FDD mode and the UE is in the half-FDD mode, the resource scheduling method provided by the embodiment of the present invention can improve the resource allocation efficiency of the half-duplex FDD system.

It should be understood that there is a control channel in the current technology. When only one control channel is stored, scheduling a large amount of data resources on the control channel causes a problem that the control channel is limited, thereby making various UEs in the current M2M. The transmission rate is not high. In the future M2M system, there may be several data channels combined for use. When there are multiple control channels, in the scenario where there are no multiple control channels in the prior art, how to schedule data resources is scheduled. .

FIG. 1 is a schematic flowchart of a resource scheduling method according to the present invention. The resource scheduling method in this embodiment includes the following.

101. The network side device allocates a control channel to the at least one data channel, and establishes a mapping relationship between the control channel and the data channel, where the mapping relationship is a mapping between a control time slot in the control channel and a data time-frequency resource in the data channel. Relationship, the network side device notifies all the UEs of the mapping relationship.

The data channel includes an uplink data channel and/or a downlink data channel.

For example, the network side device may notify the entire UE of the mapping relationship through a system broadcast or a paging message, which is not limited in this embodiment. The content of the scheduling indication information of the control channel in the narrowband system is compressed, so that the scheduling indication information only includes part of the information of the time-frequency resource location of the data channel. Therefore, the UE needs to know in advance that each control channel can be scheduled. The time-frequency resource range corresponding to the data channel.

In this embodiment, all UEs in the location refer to all UEs in the coverage area of the network side device.

102. When a network side device needs to schedule a target UE, the network side device is the target.

The UE allocates time-frequency resource location information;

103. The network side device generates scheduling information of the at least one data channel according to the time-frequency resource location information and the mapping relationship, where the scheduling information causes the target UE to perform data transmission according to the time-frequency resource location information.

For example, the scheduling information includes: an identifier of the target UE, and time-frequency resource location information within a time-frequency resource range of the data channel that the control channel can schedule.

It should be noted that the target UE identifier is a unique identifier assigned by the network side device to the target UE, and may be allocated when accessing or initial access.

In this embodiment, the time-frequency resource location information may be: a location of the virtual resource corresponding to the time-frequency resource; or a physical location of the time-frequency resource; or a time of the control channel capable of scheduling the data channel corresponding to the time slot. Relative position information within the frequency resource range.

It should be noted that the foregoing target UE is a UE pre-scheduled by the network side device. The target UE may be all UEs or at least one of all UEs.

104. The network side device sends the scheduling information to the target UE by using the control channel. According to the foregoing embodiment, the resource scheduling method in this embodiment uses a network side device to allocate a control channel to at least one data channel, and establishes a mapping relationship between the control channel and the data channel, where the mapping relationship is in a control channel. Controlling a mapping relationship between the time slot and the data time-frequency resource in the data channel, and notifying the mapping relationship to the UE, so that the target UE can obtain the mapping relationship between the control time slot in the control channel and the data time-frequency resource in the data channel in advance. Data communication is implemented to solve the problem of limited control channel in the prior art, and resource scheduling can be reasonably performed in a half-duplex FDD system, thereby improving the resource allocation efficiency of the half-duplex FDD system.

Optionally, the scheduling information in the foregoing step 103 may include: Uplink Scheduling Information (UI) and/or Downlink Scheduling Information (DI); wherein the UI is used to indicate scheduling a target UE for transmitting data and an uplink time-frequency resource that can be scheduled; the DI is used to indicate a scheduled destination for receiving data The UE and the downlink time-frequency resources that can be scheduled.

Optionally, when the scheduling information includes the UI and the DI, correspondingly, before the step 104, the resource scheduling method may include the step 105 not shown in the following figure:

105. The network side device determines a ratio of the UI and the DI, and location information of the UI and the DI in the control channel.

The configuration of the UI and the DI is as shown in Fig. 2. Fig. 2 shows the ratio of two control channels, that is, the control channel ratio 1 and the control channel ratio 2.

Optionally, the foregoing step 104 may be the process of step 106 described below:

106. The network side device sends the UI and the DI on the corresponding resources of the UI and the DI according to the ratio of the UI and the DI.

For example, the UI and DI can be distinguished according to the slot ratio. The slot ratio matching method includes:

If the same control channel is used to send the UI and the DI to the UE, the UI and the DI may be differentiated by using different time slot ratios. Optionally, the indication information distinguishing manner includes: sending the UI to the UE by using the same control channel. DI, then the uplink indication carried by the UI in the control slot of the control channel is different from the downlink indication carried by the DI in the control slot of the control channel. In an alternative implementation there, the UI and DI can be distinguished according to specific indications, for example, a UI indication and a DI indication can be carried in the control information.

It should be understood that in a half-duplex FDD system, the UE cannot receive and transmit data at the same time, and the UE needs to know the slot ratio relationship between the UI and the DI to implement data transmission.

Of course, in other embodiments, the foregoing UI and DI may also be sent to all UEs by using different control channels, which is not limited in this embodiment.

In an optional application scenario, the foregoing method shown in FIG. 1 may further include a step 107 not shown in the figure:

107. The network side device sends the ratio of the UI and the DI to all UEs; and/or,

The network side device sends the allocating manners of the UI and the DI to the all the UEs, and the distinguishing manner is the foregoing slot ratio matching manner, or the indication information distinguishing manner, and details are not described herein.

In this embodiment, the ratio of the UI and the DI may be the same or different, according to actual needs. Settings.

In addition, the number of uplink time-frequency resources that can be scheduled by different UIs can be different. The number of downlink time-frequency resources that can be adjusted by different DIs can also be different. Moreover, the maximum number of uplink time-frequency resources that the UI can schedule and the maximum number of downlink time-frequency resources that the DI can schedule can also be different.

The resource scheduling method will be described below by taking a control channel as an example. It should be particularly noted that the present invention is not limited thereto.

301. The network side device allocates a control channel for the uplink data channel and the downlink data channel, and establishes a correspondence between the control channel and the uplink data channel and the downlink data channel, respectively.

As shown in FIG. 3, when there is one control channel, the network side device needs to establish a mapping relationship between the control channel and the uplink data channel and the downlink data channel, as shown by the dotted line in FIG. 3, the first UI of the control channel. The second UI, the third UI, and the fourth UI respectively correspond to uplink resources 1, 2, 3, and 4 of the uplink data channel, and the first DI and the second DI of the control channel respectively correspond to the downlink data channel. Downstream resources 1 and 2 correspond.

The UE receives the control information, that is, the scheduling information. Once the UE-ID belongs to itself, the content of the control information and the previously obtained control channel and data channel mapping manner are further determined according to the time-frequency position of the received control information. The location of the corresponding uplink or downlink data resource is obtained, thereby implementing communication with the network.

Further, the upper UI and the DI ratio in the control channel can be flexibly configured, for example, can be flexibly configured according to different service types or traffic.

For example, as shown in FIG. 3, the ratio of UI and DI in the control channel ratio is the same; as shown in FIG. 4 and FIG. 5, the ratio of UI and DI in the control channel ratio is different. In Figure 4, the number of DIs is greater than the number of UIs, and the number of downlink data channels that DI can schedule is two. In Figure 5, the number of DIs is greater than the number of UIs, and the number of downlink data channels that DI can schedule is three.

Further, as shown in FIG. 6, the foregoing UI and DI may also be combined into Control Scheduling Information (CI), that is, CI may schedule an uplink data channel and a downlink data channel on the same control slot.

For example, Figure 7 shows the aforementioned format of the UI and DI. Of course, this is only for the purpose of illustrating the examples of the present invention, and the present invention includes examples that are not limited to the following:

The UI may include at least one of an identity of the target UE and the following fields:

Channel indication field, resource location field, resource length indication field, and the like. Channel indication The field specifies the scheduled channel number, and the resource location field specifies the scheduled resource location information. The lengths of DI and UI shown in Fig. 7 are 90 bits and 45 bits, respectively. Generally, a 90-bit length DI or UI can schedule 4 target UEs at a time, and each target UE can be allocated a maximum of 8 consecutive subframes; a 45-bit length DI or UI can schedule 2 target UEs at a time, each UE Up to 4 consecutive subframes can be allocated.

It should be noted that the data channel resources that each UI or DI can schedule can be frequency hopped on different frequencies. The unallocated uplink or uplink resources in Figures 3 through 6 can be used for contention.

In combination with the above description, the UI and the DI may be distinguished by different time slot ratios in the system broadcast, or may be distinguished by different control channels, or may be carried by the uplink and downlink indications in the control slots of the control channel. The case is only an example of the embodiment, and the present invention includes a manner of not limiting the scheduling information transmitted by the network side device listed above.

302. The network side device notifies the UE of an uplink data resource that can be scheduled for each time slot in each control channel and a location of the downlink data resource.

In a practical application, the network side device also needs to send the maximum uplink time-frequency resource quantity that can be scheduled by the UI and/or the maximum downlink time-frequency resource quantity that the DI can schedule to all UEs. For example, all UEs are notified by the system broadcast method of the maximum number of uplink time-frequency resources that the UI can schedule and/or the maximum number of downlink time-frequency resources that the DI can schedule.

Based on the above understanding, the resource scheduling method in the embodiment of the present invention may allocate one control channel for several uplink data channels and/or downlink data channels. The control channel includes scheduling information of the uplink data channel and/or scheduling information of the downlink data channel.

In an embodiment, the time-frequency resource location information that can be scheduled for each scheduling information may be notified in a system broadcast, or may be determined according to a protocol or an agreement.

The network side device can be flexibly configured (for example, the network side device can flexibly adjust the ratio of UI and DI in the scheduling information) to meet different service characteristics and resource occupation conditions, and adapt to different application scenarios, thereby solving the problem. In the prior art, the control channel is limited, and resource scheduling can be reasonably performed in the half-duplex FDD system, and the resource allocation efficiency of the half-duplex FDD system is improved.

In the specific application process, the foregoing scheduling information may include:

First, the position information of the UI frame and the DI frame in the control channel.

Second, each time-frequency resource location information that can be scheduled for each control frame (such as the aforementioned UI frame and DI frame). In this way, the location of the allocated resource is no longer needed in the control frame to reduce the size of the information carried in the control frame.

The resource location in the time-frequency resource location information of the location may be an actual physical time-frequency resource location, or may be a virtual time-frequency resource location. Virtual resource locations can be mapped to physical time-frequency resource locations. And the time-frequency resource location information may further include: a starting position of the physical resource that can be scheduled by each control frame in time, and a starting position on the frequency, to implement compression scheduling information.

Third, if there are multiple control channels, each control channel corresponds to a data channel that can be scheduled, or a data channel that can be scheduled for each control frame in each control channel.

Since the UE adopts the half-duplex mode, the network side device such as the base station can better compress the scheduling information. It should be noted that the time-frequency resources scheduled by the foregoing control frame may be orthogonal to each other within a certain period.

Certainly, the network side device may send the scheduling information including the foregoing content to the target UE by using the same control channel, or may send the scheduling information including the foregoing content to the UE by using different control channels.

801. Receive a mapping relationship that is notified by the network side device, where the mapping relationship is a mapping relationship between the control time slot in the control channel and the data time-frequency resource in the data channel after the network side device allocates the control channel to the at least one data channel. .

Receive scheduling information that is sent by the network side device by using the control channel, where the scheduling information is scheduling of at least one data channel generated by the network side device according to a data time-frequency resource location and the mapping relationship in a data channel. And the time-frequency resource location is allocated to the target UE when the network side device needs to schedule a target UE.

803. Acquire, according to the scheduling information and the mapping relationship, a data time-frequency resource location of a data channel allocated by the network side to a target UE.

It can be understood that the mapping relationship between the control channel and the data channel is as follows: The system broadcast of the network side device notifies all UEs, and the control slot 1 on the control channel No. 1 corresponds to the frame number 1 of the uplink data channels 1 and 2, Frame number 2, frame number 3, frame number 4. If the scheduling information includes the IDs of the target UE1 and the target UE2 (IDentity, ID), the UE1 and the target UE2 occupy the channel 1 according to the order in which the UE IDs appear, and the UE2 occupies the channel 2. The scheduling information is only for all UEs. The occupied resources are frame number 1, frame number 2, frame number 3, and number of consecutive resources in frame number 4 in each data channel. For example, the target UE1, the allocated resource identifier is 01; Target UE2, the assigned resource identifier is 11. That is to say, the network side device allocates the frame number 1 of the data channel 1 and the frame number 2 resource for the target UE1, and allocates the frame number 1, the frame number 2, the frame number 3, and the frame number 4 of the data channel 2 for the target UE2. resource of.

800. Send a resource request message to the network side device, where the resource request message is used to enable the network side device to allocate time-frequency resources to the target UE.

For example, the UE may listen to the control channel to obtain an idle uplink data frame, and send the resource request message to the network side device by using the idle uplink data frame.

Or the UE receives the indication information sent by the network side device, where the indication information is used to indicate the subframe allocated to the UE to use the resource request message; the UE may be in the subframe indicated by the indication information, The network side device sends the resource request message.

In a specific application, the UE generally listens to the mapping relationship and scheduling information sent by the network side device after sending the resource request message. If the UE reads the identity (such as an ID) in the received scheduling information, the UE may perform scheduling according to the scheduling. Information is transmitted for data.

Optionally, before step 804, the foregoing data transmission method may further include the step 804a not shown in the following figure:

804a: Receive a ratio of UI and DI in the scheduling information sent by the network side device, and/or, Receiving a method for distinguishing UI and DI in the scheduling information sent by the network side device, and/or,

Receiving the maximum amount of uplink time-frequency resources that can be scheduled by the UI sent by the network side device, and/or,

And receiving, by the network side device, a maximum downlink time-frequency resource that can be scheduled by the DI.

The network-side device can reasonably perform resource scheduling in the half-duplex FDD system, and improves the half-duplex FDD. System resource allocation efficiency.
