The resource allocation method and the device thereof provided by the application are described in detail below with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart of a resource allocation method according to an embodiment of the present application. It should be noted that, the resource allocation method in the embodiment of the present application is executed by the terminal device. The method may be performed independently or in combination with any of the other embodiments of the present application. As shown in fig. 2, the method may include the steps of:

in step 201, semi-persistent resource configuration information sent by a network device is received, where the semi-persistent resource configuration information is carried in a radio resource control RRC release message.

In the embodiment of the present application, the terminal device can receive Semi-persistent (Semi-Persistent Scheduling, SPS, semi-persistent scheduling) resource configuration information sent by the network device, where the Semi-persistent resource configuration information is carried in a radio resource control RRC (Radio Resource Control) release (release) message. The terminal equipment can determine the corresponding semi-persistent resources according to the semi-persistent resource configuration information.

The semi-persistent resource is a periodically allocated resource, and the resource scheduling mode of the semi-persistent scheduling may be referred to as "one-time allocation, multiple-time use", and the terminal device may use the resource for data transmission every one period.

It can be understood that the semi-persistent resource configuration information is carried in an RRC release message, and the terminal device enters an idle state or an inactive state after receiving the RRC release message.

In the embodiment of the present application, the semi-persistent resource configuration information may be indicated explicitly or implicitly.

As an example, if the terminal device acquires the semi-persistent resource configuration information in the CONNECTED state (CONNECTED), the network device may not explicitly provide the semi-persistent resource configuration information in the RRC release message, and may implicitly (e.g., with a 1bit indication, take on a value of 1) indicate that the semi-persistent resource configuration information in the CONNECTED state is also used in the idle state or inactive state of the terminal device.

In the embodiment of the present application, when the terminal device enters an idle state or a non-active state, the semi-persistent resource configuration information can be reserved. As an example, the RRC layer of the terminal device maintains the semi-persistent resource configuration information.

At a specific stage after the terminal device initiates the data transmission procedure, the RRC layer can recover the semi-persistent resource configuration information, i.e., the RRC layer configures the MAC (Medium Access Control ) layer so that the MAC layer can use the semi-persistent resource configuration information.

In some embodiments, the data channel may be a PDSCH (Physical Downlink Shared Channel ) data channel.

In some embodiments, the terminal device is further capable of obtaining a terminal device connection status for which the semi-persistent resource is applicable. Alternatively, the terminal device can determine the connection state of the terminal device to which the semi-persistent resource is applicable according to the specification of the protocol or the instruction of the network device.

As a second possible implementation manner, in response to a change of the connection state of the terminal device, and the changed connection state is not applicable to the semi-persistent resource, the terminal device can clear the semi-persistent resource.

In some embodiments, the terminal device is further capable of determining, according to an indication of the network device, a frequency domain resource region where the semi-persistent resource is applicable, for example, a cell group, a bandwidth, frequency point information, and so on where the semi-persistent resource is applicable.

Further, in response to the frequency domain resource region of the terminal device being changed, and the changed frequency domain resource region not being applicable to the semi-persistent resource, the terminal device can suspend or delete the semi-persistent resource configuration information and/or clear the semi-persistent resource.

That is, as a first possible implementation manner, in response to a change of the frequency domain resource area of the terminal device, where the changed frequency domain resource area is not applicable to the semi-persistent resource, the terminal device can suspend or delete the semi-persistent resource configuration information.

As a second possible implementation manner, in response to a change of the frequency domain resource area of the terminal device, the terminal device can clear the semi-persistent resource, where the changed frequency domain resource area is not applicable to the semi-persistent resource.

As a third possible implementation manner, in response to a change of the frequency domain resource area of the terminal device, where the changed frequency domain resource area is not applicable to the semi-persistent resource, the terminal device can suspend or delete the semi-persistent resource configuration information and clear the semi-persistent resource.

In some embodiments, the terminal device can also determine the type of small data transfer SDT procedure, such as mtstt or MOSDT, for which the semi-persistent resource is applicable, or can indicate that the semi-persistent resource is not applicable to the SDT procedure, as specified by the protocol or as indicated by the network device.

Further, in response to the terminal device being in the SDT process for which the semi-persistent resource is applicable, the control information is monitored.

In some embodiments, the terminal device is further capable of determining a stage of the small data transfer SDT procedure for which the semi-persistent resource is applicable according to a protocol specification or according to an indication of the network device.

Further, the control information is monitored in response to the terminal device being in a stage of an SDT process for which the semi-persistent resource is applicable.

In some embodiments, the terminal device is further capable of determining an effective time of the semi-persistent resource configuration information according to an indication of the network device, wherein the semi-persistent resource configuration information is available during the effective time.

Further, the terminal device can suspend or delete the semi-persistent resource configuration information and/or clear the semi-persistent resource in response to exceeding the validation time of the semi-persistent resource configuration information.

That is, as a first possible implementation, the terminal device can suspend or delete the semi-persistent resource configuration information in response to exceeding the validation time of the semi-persistent resource configuration information.

As a second possible implementation, the terminal device is able to clear the semi-persistent resource in response to exceeding the validation time of the semi-persistent resource configuration information.

As a third possible implementation manner, the terminal device can suspend or delete the semi-persistent resource configuration information and clear the semi-persistent resource in response to exceeding the validation time of the semi-persistent resource configuration information.

In some embodiments, the terminal device is further capable of determining a type of data carried on the semi-persistent resource according to an indication of the network device.

In summary, by receiving the semi-persistent resource configuration information sent by the network device, the semi-persistent resource configuration information is carried in the radio resource control RRC release message, and according to the semi-persistent resource configuration information, the semi-persistent resource of the data channel transmission of the terminal device is determined, so that the network device can perform data transmission by allocating periodic resources and the terminal device in a non-connection state, thereby improving the efficiency of data transmission, shortening the delay of data transmission, effectively reducing the signaling overhead, saving resources, and reducing the energy consumption of the terminal device.

Referring to fig. 3, fig. 3 is a flowchart of a resource allocation method according to an embodiment of the present application. It should be noted that, the resource allocation method in the embodiment of the present application is executed by the terminal device. The method may be performed independently or in combination with any of the other embodiments of the present application. As shown in fig. 3, the method may include the steps of:

in step 301, semi-persistent resource configuration information sent by a network device is received, where the semi-persistent resource configuration information is carried in a radio resource control RRC release message.

In the embodiment of the present application, the terminal device may receive the semi-persistent resource configuration information sent by the network device, where the semi-persistent resource configuration information is carried in the radio resource control RRC release message. The terminal equipment can determine the corresponding semi-persistent resources according to the semi-persistent resource configuration information.

As an example, if the terminal device acquires the semi-persistent resource configuration information in the connected state, the network device may not explicitly provide the semi-persistent resource configuration information in the RRC release message, and may indicate that the semi-persistent resource configuration information in the connected state is also used in the idle state or the inactive state of the terminal device by an implicit manner (e.g., using a 1bit indication, with a value of 1).

Wherein the semi-persistent resource configuration information may include at least one of:

a period of the semi-persistent resource;

resource configuration information of uplink feedback information;

aggregation level of downlink data channels;

control information of the semi-persistent resource.

The HARQ process management configuration information can be used to determine the HARQ process corresponding to the semi-persistent resource, for example, the HARQ process management configuration information may include the number of HARQ processes allocated to the semi-persistent resource, or a starting HARQ number.

The resource configuration information of the uplink feedback information can be used to determine a resource configured for uplink feedback corresponding to the semi-persistent resource, for example, the resource configuration information of the uplink feedback information may include an uplink PUCCH (physical uplink control channel) resource for HARQ ACK (acknowledgement) feedback of a downlink HARQ process.

The aggregation level of the downlink data channel may be, for example, the number of repeated transmissions of data in the PDSCH.

The control information of the semi-persistent resource can be used to control the semi-persistent resource, and as an example, the control information may be CS-RNTI (Configured Scheduling Radio Network Temporary Identity, radio network temporary identity configuring scheduling).

Further, the control information may be DCI in CS-RNTI PDCCH.

Optionally, the control information of the semi-persistent resource is used to indicate at least one of:

activation or deactivation of the semi-persistent resource;

the available resource allocation information of the semi-persistent resource;

The available resource allocation information of the semi-persistent resource can indicate available resources of a data channel transmitted by using the semi-persistent resource. As an example, the control information may be DCI in CS-RNTI PDCCH, information that can indicate available PRBs (Physical Resource Block, physical resource blocks) of PDSCH, and the like.

And the data retransmission instruction corresponding to the semi-persistent resource is used for indicating the data retransmission corresponding to the semi-persistent resource. As an example, the control information may be DCI in CS-RNTI PDCCH capable of indicating a dynamically scheduled retransmission of HARQ process 1, where HARQ process 1 is the HARQ process allocated for the semi-persistent resource usage.

As an example, the network device may activate and deactivate the semi-persistent resource through CS-RNTI PDCCH.

In some embodiments, the terminal device is further capable of receiving a transmission resource configuration sent by the network device, where the transmission resource configuration is used to determine a transmission resource where the control information is located. The terminal device can monitor the control information on the transmission resource.

The PRB identity indicates a number of PRBs to which the semi-persistent resource applies, such as PRB-1, and the network device may indicate a number of at least one PRB to which the semi-persistent resource applies. The PRB range indicates PRBs within a region where the semi-persistent resource is applicable, such as from PRB-0 to PRB-10.

In the embodiment of the present application, the final frequency domain resource region to which the semi-persistent resource is applicable may be indicated by an explicit manner or may be indicated by an implicit manner.

As an example, the indication may be performed in an implicit manner, where the terminal device may use the frequency domain resource region to which the received semi-persistent resource configuration information belongs as a final frequency domain resource region to which the semi-persistent resource is applicable. For example, the terminal device may use the cell, BWP, or cell group to which the persistent resource configuration information belongs, as a terminal frequency domain resource region to which the semi-persistent resource is applicable.

In the embodiment of the application, the terminal device can determine the stage of the small data transmission SDT process to which the semi-persistent resource is applicable according to the specification of the protocol or the instruction of the network device.

Wherein the stage of the SDT process for which the semi-persistent resource is applicable includes at least one of: an initial data transmission stage and a subsequent data transmission stage.

In addition, the connection state change instruction information may be, as an example, an RRC connection release message or an RRC connection restoration message. The RRC connection release message releases the terminal device to an idle state or an inactive state, and the RRC connection restore message transitions the terminal device to a connected state.

In step 604, the control information is monitored in response to the terminal device being in a stage of the SDT procedure for which the semi-persistent resource is applicable.

In the embodiment of the present application, the terminal device monitors the control information of the semi-persistent resource only when the terminal device is in the stage of the SDT process to which the semi-persistent resource is applicable, using the semi-persistent resource configuration information.

During the operation of the validation period timer, the terminal device considers the semi-persistent resource configuration information to be available. If the validation period timer expires, the terminal device suspends or deletes the semi-persistent resource configuration information and/or clears the semi-persistent resource.
