Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

The term "comprising" and any variations thereof in the description and claims of this application are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or device comprising a series of steps or units is not necessarily limited to the explicit instead of those steps or elements explicitly listed, other steps or elements not explicitly listed or inherent to the process, method, product or apparatus may be included. In addition, the use of "and/or" in the description and claims means at least one of the connected objects, such as A and/or B, means that there are three situations including A alone, B alone, and both A and B.

In the embodiments of the present invention, words such as "exemplary" or "for example" are used as examples, illustrations or illustrations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present invention shall not be construed as being more preferred or more advantageous than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete manner.

Before a detailed description of the technical solutions of the embodiments of the present invention, a brief introduction will be made to the technologies related to the uplink out-of-sync state.

In the 5G system, the network side device can configure periodic uplink resources, that is, CG (Configured Grant, configured uplink grant) for sending uplink data.

After receiving the downlink signal, the terminal can determine the position of the subframe of the downlink signal. In order to avoid uplink interference, the network-side device must ensure that the signals sent by different terminals arrive at a fixed time, so the network-side device needs to configure an uplink timing advance, TA (Timing Advance), for the uplink transmission of the terminal. After the terminal receives the TA value, if the terminal wants to send an uplink signal, the terminal then advances the TA time value to send the uplink signal with reference to the position of the downlink subframe.

Since the location of the terminal is constantly changing, it is necessary to maintain the validity of the TA value. The network side device may set a timer (namely TAT, timeAlignmentTimer) for the TA value of the terminal, so as to maintain the TA value. The timer is started when the TA is delivered to the terminal, and the network side device sends a new TA value to the terminal before the timer expires. According to the timer set by the network side device, the terminal starts or restarts when receiving the TA value, and considers the TA value invalid after the timer expires. At this time, the terminal's uplink behavior is out of synchronization, that is, the terminal is in the uplink non-synchronized state (Uplink Non-synchronized). In this state, the terminal cannot send uplink signals, so it cannot use CG. If the terminal has uplink data arriving at this time , then the terminal needs to trigger the random access process first, and after obtaining the uplink signal TA through the random access process, it can send the uplink signal and use the CG in the state of uplink synchronization.

For the two-step random access (2-Step RACH) process, the terminal can send PRACH+PUSCH in the request information (for example, MsgA) in the out-of-synchronization state. Specifically, as shown in FIG. 1 , in step 0, the network side device configures two-step random access configuration information for the terminal, such as transmission resource information corresponding to MsgA and MsgB. In the resource configuration information, the terminal triggers the 2-step RACH process, and sends MsgA to the network side device, such as through PUSCH (Physical Uplink Shared Channel, physical uplink shared channel). At the same time, the terminal may also send PRACH (Physical Random Access Channel, physical random access channel) information to the network side equipment. In step 2, after sending MsgA, the terminal monitors the reception of MsgB within a period of time, that is, the RAR (Random Access Response, random access response) window. If the terminal fails to receive MsgB, the terminal resends MsgA.

However, in the random access process, the protocol only allows one random access process to exist, which will cause the terminal to be unable to continuously send uplink data after sending a random request data, resulting in a large delay in uplink data .

In view of this, in order to solve the above problems, embodiments of the present invention provide an uplink transmission method, a resource configuration method, a terminal, and a network side device.

Embodiments of the present invention will be described below in conjunction with the accompanying drawings. The embodiments provided by the present invention can be applied in a wireless communication system. The wireless communication system may be a 5G system, or an evolved long term evolution (Evolved Long Term Evolution, eLTE) system, or a subsequent evolution communication system.

FIG. 2 is a structural diagram of a network system provided by an embodiment of the present invention. As shown in FIG. 2 , it includes a terminal 11 and a network side device 12, wherein the terminal 11 may be a mobile communication device, such as a mobile phone or a tablet computer (Tablet Personal Computer), Laptop Computer (Laptop Computer), Personal Digital Assistant (PDA), Mobile Internet Device (Mobile Internet Device, MID) or Wearable Device (Wearable Device), etc. It should be noted that , the specific type of the terminal 11 is not limited in this embodiment of the present invention. The above-mentioned network side device 12 may be a 5G network side device (for example: gNB, 5G NR NB), or may be a 4G network side device (for example: eNB), or may be a 3G network side device (for example: NB), or a subsequent evolution The network-side device in the communication system, etc. It should be noted that the specific type of the network-side device 22 is not limited in this embodiment of the present invention.

FIG. 3 and FIG. 4 are respectively flowcharts of two uplink transmission methods applied to the network system shown in FIG. 2 provided by the embodiments of the present invention. In these two uplink transmission methods, the network side equipment configures uplink resources in different ways, and thus, the terminal uses uplink resources in different ways for uplink transmission. The two uplink transmission methods are specifically described below respectively.

As shown in Figure 3, the method includes the following steps:

Step 201: The network side device sends resource configuration information to the terminal.

Wherein, the above resource configuration information is used to configure periodic uplink resources, and the uplink resources include first channel resources and second channel resources. The above resource configuration information includes the start time information of the uplink resource.

Step 202: The terminal receives resource configuration information sent by the network side device.

Step 203: The terminal performs uplink transmission using the uplink resource configured by the resource configuration information.

The above resource configuration information may also include period information of uplink resources and resource allocation information of each period.

In this embodiment, since the resource configuration information clearly indicates the start time information of the uplink resource, the terminal can determine the time position of the uplink resource in each cycle, therefore, when the terminal needs to perform uplink transmission, it can directly Uplink transmission is performed on the periodic uplink resource configured by the side device.

In this embodiment, the network-side device configures periodic uplink resources for the terminal. In this way, when the terminal has multiple uplink data to send, it can directly perform multiple uplink data on the periodic uplink resources configured by the network-side device. send. In this way, when the terminal has a plurality of uplink data to be sent, it can continuously send uplink data, thereby reducing the delay in sending uplink data and improving communication performance.

As shown in Figure 4, the method includes the following steps:

Step 301: The network side device sends resource configuration information to the terminal.

Wherein, the above resource configuration information is used to configure periodic uplink resources, and the uplink resources include first channel resources and second channel resources. The above resource configuration information does not include the start time information of the uplink resource.

Step 302: The terminal receives resource configuration information sent by the network side device.

Step 303: The network side device sends an activation instruction to the terminal.

Wherein, the above-mentioned activation indication is used to indicate to activate the above-mentioned uplink resource.

Step 304: The terminal performs uplink transmission using the uplink resources activated by the activation indication.

The above resource configuration information may also include period information of uplink resources.

In this embodiment, since the resource configuration information does not explicitly indicate the start time information of the uplink resource, the time position of the uplink resource available to the terminal is still uncertain. Therefore, when the terminal needs to perform uplink transmission, it cannot directly perform uplink transmission on the uplink resources, but needs to determine the available uplink resources according to the activation indication sent by the network side device, and the available uplink resources are the activated resources of the activation indication. upstream resources.

In this embodiment, the network-side device configures periodic uplink resources for the terminal. In this way, when the terminal has multiple uplink data to send, after the network-side device activates the periodic uplink resources, the activated periodic A plurality of uplink data are sent on the uplink resource. In this way, when the terminal has a plurality of uplink data to be sent, it can continuously send uplink data, thereby reducing the delay in sending uplink data and improving communication performance.

FIG. 5 and FIG. 6 are respectively flowcharts of two uplink transmission methods applied to a terminal provided by an embodiment of the present invention. In these two uplink transmission methods, the network side equipment configures uplink resources in different ways, and thus, the terminal uses uplink resources in different ways for uplink transmission. The two uplink transmission methods are specifically described below respectively.

As shown in Figure 5, the uplink transmission method is applied to the terminal, and the method includes the following steps:

Step 401: Receive resource configuration information sent by a network side device, the resource configuration information is used to configure periodic uplink resources, and the uplink resources include first channel resources and second channel resources.

Step 402: When the resource configuration information includes start time information of the uplink resources, perform uplink transmission using the uplink resources configured by the resource configuration information.

In this embodiment, since the resource configuration information clearly indicates the start time information of the uplink resource, the terminal can determine the time position of the uplink resource in each cycle, therefore, when the terminal needs to perform uplink transmission, it can directly Uplink transmission is performed on the periodic uplink resource configured by the side device.

In this embodiment, the network-side device configures periodic uplink resources for the terminal. In this way, when the terminal has multiple uplink data to send, it can directly perform multiple uplink data on the periodic uplink resources configured by the network-side device. send. In this way, when the terminal has a plurality of uplink data to be sent, it can continuously send uplink data, thereby reducing the delay in sending uplink data and improving communication performance.

The above-mentioned first channel resources may be control channel resources, for example, PRACH resources; the above-mentioned second channel resources may be data channel resources, for example, PUSCH resources. For example, if the network side device configures uplink resources with a period of 1 ms, and each uplink resource opportunity includes 1 PRACH resource and 1 PUSCH resource, then the terminal needs to send PUSCH and PRACH at the same time when sending uplink data.

The above resource configuration information may also include period information of uplink resources and resource allocation information of each period, that is, the resource configuration information includes period of uplink resources, start time information of uplink resources and specific resource allocation of each period information.

The period of the first channel resource may be equal to the period of the second channel resource.

Resource allocation information for each cycle may include:

Relative position information of the first channel resource and the second channel resource in each period; or,

Allocation information of the first channel resource in each period; or,

Allocation information of the second channel resource in each period.

For example, the network side device configures uplink resources with a period of 1 ms, and the start time position of the uplink resources is: SFN (System frame number, system frame number)=1, slot (time slot)=1, symbol (symbol)=1. Each uplink resource opportunity includes 1 PRACH resource and 1 PUSCH resource. For a specific resource allocation time position (such as slot1), the resource configuration information may also include specific PRACH resource allocation information at the time position, such as the PRB (Physical Resource Block) corresponding to RO (RACH Resource, random access resource) , the location of the physical resource block). The resource configuration information may also include specific PUSCH resource allocation information at the time position, such as PRB position and quantity, MCS (Modulation and coding scheme, modulation and coding scheme) and so on.

The start time information of the uplink resource may include at least one of the start time position of the first channel resource and the start time position of the second channel resource.

Specifically, the start time information of the uplink resources may include any of the following:

The start time position of the first channel resource, for example, the start time position of the PRACH resource configured by the network side device is: SFN=1, slot=1, symbol=1, and the period of the PRACH resource is 1 ms;

The start time position of the second channel resource, for example, the start time position of the PUSCH resource configured by the network side device is: SFN=1, slot=1, symbol=1, and the period of the PUSCH resource is 1 ms;

The start time position of the first channel resource and the start time position of the second channel resource, for example, the start time position of the PRACH resource configured by the network side device is: SFN=1, slot=1, symbol=1, and the period of the PRACH resource is 1 ms, the start time position of the PUSCH resource configured by the network side device is: SFN=1, slot=2, symbol=1, and the period of the PUSCH resource is 1 ms.

When the start time information of the uplink resource only includes the start time position of the first channel resource, the resource configuration information may also include the second channel corresponding to the position of the first channel resource in each cycle The location of the resource.

For example, the start time position of the PRACH resource configured by the network side device is: SFN=1, slot=1, symbol=1, and the period of the PRACH resource is 1 ms, then for the time position of the PRACH of each period, it is related to the PRACH resource allocation The position of the PUSCH resource corresponding to the position is the position of x slots after the time position of the PRACH resource. For example, x=1, the time position of PRACH is: SFN=1, slot=1, symbol=1, then the time position of the PUSCH resource corresponding to the PRACH resource is: SFN=1, slot=1+1=2, symbol=1.

When the start time information of the uplink resource only includes the start time position of the second channel resource, the resource configuration information may also include the first Location information of channel resources.

For example, the start time position of the PUSCH resource configured by the network side device is: SFN=1, slot=2, symbol=1, and the period of the PUSCH resource is 1 ms, then for the time position of the PUSCH of each period, the PUSCH resource allocation The position of the PRACH resource corresponding to the position is the position of x slots before the time position of the PUSCH resource. For example, x=1, the time position of PUSCH is: SFN=1, slot=2, symbol=1, then the time position of the PRACH resource corresponding to the PUSCH resource is: SFN=1, slot=2-1=1, symbol=1.

As shown in Figure 6, the uplink transmission method is applied to the terminal, and the method includes the following steps:

Step 501: Receive resource configuration information sent by a network side device, the resource configuration information is used to configure periodic uplink resources, and the uplink resources include first channel resources and second channel resources.

Step 502: If the resource configuration information does not include the start time information of the uplink resource, after receiving the activation indication sent by the network side device, use the uplink resource activated by the activation indication to perform uplink transmission.

In this embodiment, since the resource configuration information does not explicitly indicate the start time information of the uplink resource, the time position of the uplink resource available to the terminal is still uncertain. Therefore, when the terminal needs to perform uplink transmission, it cannot directly perform uplink transmission on the uplink resources, but needs to determine the available uplink resources according to the activation indication sent by the network side device, and the available uplink resources are the activated resources of the activation indication. upstream resources.

In this embodiment, the network-side device configures periodic uplink resources for the terminal. In this way, when the terminal has multiple uplink data to send, after the network-side device activates the periodic uplink resources, the activated periodic A plurality of uplink data are sent on the uplink resources. In this way, when the terminal has a plurality of uplink data to be sent, it can continuously send uplink data, thereby reducing the delay in sending uplink data and improving communication performance.

The above-mentioned first channel resources may be control channel resources, for example, PRACH resources; the above-mentioned second channel resources may be data channel resources, for example, PUSCH resources. For example, if the network side device configures uplink resources with a period of 1 ms, and each uplink resource opportunity includes 1 PRACH resource and 1 PUSCH resource, then the terminal needs to send PUSCH and PRACH at the same time when sending uplink data.

The above resource configuration information may also include cycle information of uplink resources, and further, the above resource configuration information may also include resource allocation information for each cycle. That is to say, the resource configuration information may only include the period of the uplink resource, or may include the period of the uplink resource and resource allocation information of each period, but the resource configuration information does not include the start time information of the uplink resource.

The period of the first channel resource may be equal to the period of the second channel resource.

Resource allocation information for each cycle may include:

Relative position information of the first channel resource and the second channel resource in each period; or,

Allocation information of the first channel resource in each period; or,

Allocation information of the second channel resource in each cycle.

For example, the position of the PRACH resource is the first x slots relative to the position of the PUSCH resource, and the position of the PUSCH resource is the last x slots relative to the position of the PRACH resource.

The specific allocation information of the PRACH resource may include: for any specific slot, the specific format (such as preamble format A1) adopted by the PRACH resource, the used preamble range (such as preamble index 1) and so on.

The specific allocation information of the PUSCH resource is: for any specific slot, the specific PRB allocation position of the PUSCH resource (such as PRB numbers 1-3) and the used MCS.

In this embodiment, after receiving the activation indication sent by the network side device, the terminal can perform uplink transmission on the activated uplink resource. After receiving the deactivation indication sent by the network side device, it may stop using the uplink resource activated by the activation indication to perform uplink transmission, that is, the previously activated uplink resource is no longer available.

Optionally, the activation indication is used to indicate activation of at least one of the first channel resource at a specific location and the second channel resource at a specific location.

Specifically, the activation indication may include at least one of the following activation modes.

Activation method 1: activate the first channel resource at a specific location, for example, DCI (Downlink Control Information, downlink control information) indicates the xth location after receiving the location slot (n) from the DCI, that is, slot (n+x) is PRACH Resource location, and indicate specific PRACH resource allocation information, such as preamble range (such as preamble index1), carrier indication (such as UL or SUL carrier), BWP indication (such as BWP1), PRACH Mask index, etc.

Activation method 2: activate the PUSCH resource at a specific location, for example, DCI indicates the xth location after the DCI receiving location slot(n), that is, slot(n+x) is the PUSCH resource location, and indicates the specific allocation of PUSCH resources Information, for example, frequency domain resource allocation (PRB position), MCS, carrier indication (such as UL or SUL carrier), BWP indication (such as BWP1) and so on.

Activation method 3: activate PRACH and PUSCH resources at a specific location, for example, DCI indicates the xth location after receiving location slot(n) from the DCI, that is, slot(n+x) is the PRACH resource location, and indicates the specific location of the PRACH resource Allocation information, for example, preamble range (such as preamble index 1), carrier indication (such as UL or SUL carrier), BWP indication (such as BWP1), PRACH Mask index and so on. At the same time, the DCI also indicates the y-th position after the DCI receiving position slot(n), that is, slot(n+y) is the PUSCH resource position, and indicates specific allocation information of PUSCH resources, for example, frequency domain resource allocation (PRB location), MCS, carrier indication (such as UL or SUL carrier), and BWP indication (such as BWP1), etc.

For activation mode 1, after receiving the activation indication, the terminal uses the PRACH resource indicated in the activation indication as the PRACH resource in each resource allocation period, and simultaneously activates the PUSCH resource corresponding to the PRACH resource.

For example, the resource configuration information configures the resource allocation period as 1 ms, and also configures the specific allocation information of PUSCH resources (such as the allocation position of PRB (such as PRB number 1-3) and the MCS used), and configures the PUSCH resource position as Relative to the first slot after the PRACH resource location. If the activation indication is used to activate the PRACH resource at slot1, the PUSCH resource is at slot2, and the resources available to the terminal are the PRACH resource at slot1 and the PUSCH resource at slot2 every 1 ms.

For activation mode 2, after receiving the activation indication, the terminal uses the PUSCH resource indicated in the activation indication as the PUSCH resource in each resource allocation period, and simultaneously activates the PRACH resource configured in the resource configuration information corresponding to the PUSCH resource.

For example, the resource configuration information configures the resource allocation cycle as 1 ms, and also configures the specific allocation information of PRACH resources (such as pramble format A1 and preamble index 1), and configures the PRACH resource position as the first relative to the PUSCH resource position. slot. If the activation indication is used to activate the PUSCH resource at slot2, the PRACH resource is at slot1, and the resources available to the terminal are the PRACH resource at slot1 and the PUSCH resource at slot2 every 1 ms.

For the third activation mode, after receiving the activation indication, the terminal uses the PRACH resource and the PUSCH resource indicated in the activation indication as resources for each resource allocation period.

For example, the resource configuration information configures the resource allocation cycle as 1 ms. If the activation indication is used to activate the PRACH resource at slot1 and the PUSCH resource at slot2, the resources that the terminal can use are the PRACH resource at slot1 and the PUSCH resource at slot2 every 1 ms. PUSCH resources.

Optionally, the deactivation indication is used to indicate deactivation of at least one of the first channel resource and the second channel resource.

Specifically, the deactivation instruction may include at least one of the following deactivation manners.

Deactivation mode one: deactivate the PRACH resources, for example, the DCI indicates to deactivate the PRACH resources configured by the resource configuration information.

Deactivation mode two: deactivate the PUSCH resource, for example, the DCI indicates to deactivate the PUSCH resource configured by the resource configuration information.

Deactivation mode three: deactivate the PRACH and PUSCH resources, for example, the DCI indicates to deactivate the PRACH resources and PUSCH resources configured in the resource configuration information.

For the above deactivation manners, the terminal may simultaneously deactivate the PRACH resource and the PUSCH resource configured in the resource configuration information.

In step 502 and step 602, the terminal can use the uplink resource configured by the resource configuration information to perform uplink transmission in any of the following scenarios:

When the terminal is in an uplink out-of-sync state, the terminal uses the uplink resources for uplink transmission; or,

In the case of a beam failure, the terminal uses the uplink resource for uplink transmission; or,

For a specific data channel, the terminal uses the uplink resource for uplink transmission; or,

In the case of primary and secondary cell change or cell switching, the terminal uses the uplink resources to perform uplink transmission; or,

During the random access process, the terminal uses the uplink resources to perform uplink transmission.

Optionally, when the terminal is in an uplink out-of-sync state, the terminal uses the uplink resources to perform uplink transmission, including:

When the terminal has uplink data arriving and the terminal is in an uplink out-of-sync state, the terminal uses the uplink resources to perform uplink transmission.

Optionally, during the random access process, the terminal uses the uplink resources to perform uplink transmission, including:

In the two-step random access process, the terminal uses the uplink resources activated by the activation indication to perform uplink transmission.

Specifically, the terminal may use the uplink resource configured by the resource configuration information to perform uplink transmission when the uplink data arrives and the uplink is out of synchronization or when the uplink is out of synchronization. For example, in the case of uplink synchronization, the terminal does not use the uplink resource configured by the resource configuration information for uplink transmission, and only uses it when the uplink data arrives, that is, there is data transmission in the RB (Radio Bearer, radio bearer) and the uplink is out of sync. The configured uplink resource performs uplink transmission. Alternatively, the terminal does not use the configured uplink resource for uplink transmission when the uplink is synchronized, and only uses the configured uplink resource for uplink transmission when the uplink is out of synchronization, that is, the resource can be used to send the DRB. Data can also be used to send control signaling, such as MAC CE (MAC Control Element, MAC Control Unit), HARQ (Hybrid Automatic Repeat reQuest, hybrid automatic repeat request) feedback, CSI (Channel State Information, channel state information) report, etc. .

When the beam fails, the terminal can use the uplink resource configured by the resource configuration information to perform uplink transmission. For example, when a beam failure occurs on the SCell (secondary cell) of the terminal, the terminal may use the configured uplink resources to report the SCell beam failure information.

For a specific data channel, the terminal can use the uplink resources configured by the resource configuration information to perform uplink transmission. For example, for data transmission of DRB1 or logical channel 1 of the terminal, the terminal can use the configured uplink resources at this time.

In the case of PSCell (Primary Secondary Cell, primary secondary cell) change or cell switching, the terminal can use the uplink resource configured by the resource configuration information to perform uplink transmission.

During the random access process, the terminal can use the uplink resource configured by the resource configuration information to perform uplink transmission. For example, for a two-step random access process, the terminal can use the configured uplink resource to send the MsgA.

The above usage rules may be configured by the network side device or stipulated through an agreement.

Optionally, if the terminal is allowed to use the uplink resource in an uplink synchronization state, the method further includes:

When the terminal is in an uplink synchronization state, use the second channel resource to perform uplink transmission.

That is to say, when the terminal is in the uplink synchronization state and uses the resources configured by the resource configuration information to transmit uplink data, the terminal only uses the second channel resources, such as PUSCH resources, for uplink transmission, and does not use the first channel resources, such as No PRACH signal is sent.

Optionally, if the terminal is not allowed to use the uplink resources in the uplink synchronization state, the method further includes:

When the terminal prepares to use the uplink resource for uplink transmission, if the terminal changes from an uplink out-of-sync state to an uplink synchronized state, then use the uplink resource to send the prepared data.

Specifically, if the terminal is only allowed to use the uplink resources configured in the resource configuration information for uplink transmission when the uplink is out of synchronization, when the terminal is about to send uplink data, if the terminal is uplink synchronized again, the terminal continues the prepared sending of data. As shown in Figure 7, the terminal prepares to use PRACH2+PUSCH2 resources for uplink data transmission at time t1, and the terminal is uplink synchronized at time t2, then the terminal continues to use PRACH2+PUSCH2 resources for uplink data transmission, but no longer uses PRACH3+PUSCH3 resources .

Optionally, the method also includes:

If the terminal receives the indication information sent by the network side device for instructing retransmission of the request information after sending the request information using the uplink resource in the random access process, stop the random access entry process, and retransmit the request information according to the indication information.

Specifically, when the terminal triggers the random access process and uses the periodic uplink resource to send request information, such as MsgA, if the terminal receives the instruction information sent by the network side device for instructing retransmission of the request information, for example , the DCI indicates to retransmit the data of the HARQ process of MsgA, then the terminal can stop the random access process, and retransmit the data of the MsgA according to the instruction information of the network side device. As shown in Figure 7, assume that the terminal triggers the two-step random access process and sends MsgA through (PRACH1+PUSCH1), the HARQ process number corresponding to the MsgA data is 0, and then the terminal monitors the reception of the two-step random access process MsgB. After sending the MsgA, the terminal receives DCI information of a specific RNTI (Radio NetworkTempory Identity wireless network temporary identifier) identifier (such as CS-RNTI (Configured Scheduling RNTI, configuration scheduling RNTI)), the DCI indicates that the terminal is numbered 0 for the HARQ process If the data is retransmitted, the terminal retransmits the data whose HARQ process number is 0 according to the DCI instruction, and at the same time stops the two-step random access process, for example, stops receiving and monitoring of MsgB.

In this embodiment, since the terminal stops the random access process, it is beneficial to save the power consumption of the terminal.

Based on the above implementations, the network-side device configures periodic uplink resources for the terminal. In this way, when the terminal has multiple uplink data to send, it can directly perform multiple uplink data on the periodic uplink resources configured by the network-side device. or, after the network side device activates the periodic uplink resource, multiple pieces of uplink data can be sent on the activated periodic uplink resource. In this way, when the terminal has a plurality of uplink data to be sent, it can continuously send uplink data, thereby reducing the delay in sending uplink data and improving communication performance.
