Description

Method and equipment for resource allocation and data transmission
The present invention claims priority of chinese patent application filed on 10/1/2019 under the name of "a method and apparatus for resource allocation and data transmission" by the chinese patent office under the application number 201910023977.8, the entire contents of which are incorporated herein by reference.
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for resource allocation and data transmission.
Background
The conventional L TE (L ong Term Evolution ) provides a Scheduling Request (SR) mechanism, that is, if a UE has no uplink data to transmit, an eNodeB (Evolved Node B) does not need to allocate uplink resources to the UE, otherwise, resource waste is caused.
Therefore, the 3GPP (Third Generation Partnership Project) protocol provides a concept of pre-configuring resources, where a network side device may pre-configure resources for a terminal, where the types of the pre-configured resources include a pre-configured resource type1 and a pre-configured resource type2, and when the terminal has a service transmission requirement, the pre-configured resources may be used for transmission, thereby reducing transmission delay, saving a delay for the terminal to send a scheduling request, obtain an uplink resource for buffer reporting, and retransmit data.
Specifically, when the preconfigured resource is configured for the terminal, the network side device and the terminal may negotiate a data start point that the terminal is about to arrive, but actually, the start point of the preconfigured resource configured by the network side device is hardly completely matched with the data start point that the terminal arrives, and therefore, the terminal may need to wait for a next preconfigured resource period to send data, so that although the preconfigured resource alleviates the problem of transmission delay, the terminal cannot meet the delay requirement of the terminal for a scenario with a high delay requirement, for example, an important scenario-UR LL C (Ultra Reliable L ow L inherent Communications, Ultra Reliable low delay) scenario proposed in the current 5G system, where the end-to-end delay of the scenario is required to reach 0.5 ms.
In summary, the current method of pre-configuring resources has a large transmission delay, and cannot meet the low-delay service requirement of the 5G system.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Some of the words that appear in the text are explained below:
1. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
2. The UR LL C scenario in the embodiments of the present invention is suitable for industrial applications and control, traffic safety and control, remote manufacturing, remote training, and remote surgery, and requires an end-to-end delay of up to 0.5ms (milliseconds).
3. In the embodiment of the invention, when the network side equipment configures the resource of the preconfigured resource type1 for the terminal, the resource configuration is effective, and the terminal can use the resource to perform data transmission without being activated by the network side equipment through an additional instruction.
4. The activation in the embodiment of the present invention refers to that, for an action of the preconfigured resource type2, a network side device needs to activate the resource of the preconfigured resource type2 through a PDCCH order, and for a terminal, only the activated resource of the preconfigured resource type2 can be used for data transmission.
5. The terminal referred in the embodiment of the invention is a mobile phone, a platform and the like.
6. The network side equipment referred by the embodiment of the invention is a macro base station, a micro base station and the like.
The application scenario described in the embodiment of the present invention is for more clearly illustrating the technical solution of the embodiment of the present invention, and does not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by a person skilled in the art that with the occurrence of a new application scenario, the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems. In the description of the present invention, the term "plurality" means two or more unless otherwise specified.
There are two ways to pre-configure resources, referred to as pre-configured resource Type 1(configured grantType1) and pre-configured resource Type 2(configured grant Type2) in the 3GPP protocol.
The configured grant Type1 is a periodic resource configured by the network side for the terminal by RRC signaling, and the network side notifies the terminal of the pre-configured resource period of the pre-configured resource, the start position of the pre-configured resource, the transmission resource (time frequency resource, etc.), and the transmission format (MCS, etc.) in detail. The pre-configured resource configuration is in effect. After receiving the configuration command sent by the network side, the terminal can immediately use the periodic resource to perform data transmission. Fig. 1 is a schematic diagram of a scenario in which a network-side device configures a pre-configured resource type1 for a terminal.
The configured grant Type2 is a period for the network side to allocate periodic resources to the terminal by RRC signaling and a CS-RNTI for scheduling the periodic resources. When the network side decides to allocate the actual resources, the PDCCH order is sent to indicate the starting point of the periodic resources, specific transmission resources (time frequency resources, etc.), and transmission formats (MCS, etc.). When the terminal receives the RRC signaling of the pre-configured resource, no resource is available, and the pre-configured resource is actually allocated after the activation command of the PDCCH is received. Fig. 2 is a schematic diagram of a scenario in which a network-side device configures a pre-configured resource type2 for a terminal.
When the network side equipment allocates the pre-configured resource for the terminal, the network side equipment can predict a resource starting point and roughly align with the service of the terminal, or the terminal can predict the world where data arrives, report a service model, and the network side equipment and the terminal negotiate the position of the starting point of the pre-configured resource configured for the terminal. When the data of the terminal arrives, the terminal can use the pre-configured resource to report the data. However, the starting point of the pre-configured resource is difficult to match with the data that the terminal arrives at, so the terminal may need to wait for the next pre-configured resource period to send data, referring to the scenario shown in fig. 3.
The caused transmission delay has no influence on a general low-delay-requirement scene, but for a scene with strict delay requirement, such as an important test scene-UR LL C scene proposed in the 5G technology, the UR LL C scene is suitable for industrial application and control, traffic safety and control, remote manufacturing, remote training, and remote operation, the end-to-end delay of the scene can reach 0.5ms (millisecond), and the transmission delay caused by the difficulty in matching the existing preconfigured resources with the data arriving at the terminal can cause the scene to fail to meet the requirement of the delay.
Therefore, the embodiment of the present invention provides a method and a device for resource allocation and data transmission, where a network side device allocates a pre-configured resource to a terminal in advance, where a plurality of consecutive resource allocations are provided in a pre-configured resource period of a set of pre-configured resources, and even if a starting point of the pre-configured resource does not match a starting point of data to be arrived at by the terminal, the terminal can select a closest resource from the plurality of consecutive resources for data transmission. The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.
As shown in fig. 4, an embodiment of the present invention provides a system for resource allocation and data transmission, where the system includes: a network side device 10 and a terminal 20.
A network side device 10, configured to determine a plurality of consecutive resources in a set of preconfigured resources configured for a terminal within a preconfigured resource period; the determined plurality of consecutive resources is preconfigured for the terminal.
The terminal 20 is used for determining a plurality of continuous resources pre-configured by the network side equipment; and transmitting data through the pre-configured plurality of continuous resources.
Through the method, the network side equipment configures the pre-configured resources for the terminal in advance, wherein a set of pre-configured resources have a plurality of continuous resource allocations in one pre-configured resource period. When the terminal has data to arrive, one of the plurality of continuous pre-allocated resources is selected for data transmission, and even if the starting point of the pre-allocated resource is not matched with the starting point of the data to be arrived by the terminal, the terminal can select the closest resource from the plurality of continuous resources for data transmission, thereby reducing the transmission delay.
The following describes the configuration procedures for pre-configured resource type1 and pre-configured resource type 2:
firstly, a network side device configuration pre-configuration resource process:
1. procedure to configure pre-configured resource type 1: the network side equipment configures pre-configured resources for the terminal according to auxiliary information such as a service arrival period, service data expected arrival time, expected data packet size, service data expected arrival time deviation and the like reported by the terminal, and determines a time starting point, a time-frequency resource position, a transmission format and the like of a first resource period of the pre-configured resources aiming at each set of the pre-configured resources. Wherein, for the understanding of the deviation of the predicted arrival time of the traffic data: the deviation of the predicted arrival time of the traffic data is divided into positive and negative parts, and the unit of the deviation value can be symbol, time slot, subframe or millisecond. And the network side equipment determines the number of a plurality of continuous resources in a pre-configured resource period according to the deviation between the predicted arrival time of the service data and the predicted arrival time of the service data.
For example, as shown in fig. 5, if the terminal reports the 3 rd symbol of the subframe N of the predicted arrival time of the service data, and the deviation of the predicted arrival time of the service data is positive 2 symbols, the network side device determines that the service data of the terminal may arrive after 2 symbols are delayed, so that the network side device determines that the number of multiple continuous resources in one preconfigured resource period is at least 3, specifically: the starting point is the 3 rd symbol of the subframe N, 3 resources are continuously allocated, and the 3 rd symbol of each subframe N + kT starts to pre-allocate 3 resources by setting the service period as T subframe.
The network side equipment indicates the number of continuous resources in a pre-configured resource period through RRC signaling;
2. procedure to configure pre-configured resource type 2: the network side device configures pre-configured resources for the terminal according to auxiliary information such as a service arrival period, service data expected arrival time, an expected data packet size, service data expected arrival time deviation and the like reported by the terminal, and determines a time starting point, a time-frequency resource position, a transmission format and the like of a first resource period of the pre-configured resources for each set of the pre-configured resources, wherein the mode for determining the number of the continuous resources can be a parameter mode, and is not described herein again. The network side equipment indicates the number of continuous resources in one pre-configured resource period in the pre-configured resource type2 by the following modes:
the indication method is as follows: indicated by RRC signaling;
the network side device can configure and indicate the number of continuous resources in a preconfigured resource period for the terminal through RRC signaling.
The second indication mode: indicating by a PDCCH order for activating the pre-configured resource;
the network side device may indicate the number of consecutive resources in one preconfigured resource period through a PDCCH order for activating the preconfigured resources.
In the embodiment of the present invention, regardless of the preconfigured resource type1 or the preconfigured resource type2, in a set of preconfigured resources configured for the terminal by the network side device, one preconfigured resource period has multiple consecutive resources, and for "multiple consecutive resources", it can be understood as follows:
1. contiguous resources on adjacent symbols;
2. continuous resources on adjacent time slots;
3. continuous resources on adjacent subframes;
4. adjacent continuous equidirectional transmission resources;
as shown in fig. 6, the adjacent consecutive same-direction transmission resources refer to resources that are continuously transmitted or continuously received by the same terminal, and include consecutive uplink resources or consecutive sidelink resources.
If the adjacent continuous equidirectional transmission resource is sidelink resource, the pre-configured resource is transmitted on a sidelink interface by the network side equipment configured for the sending terminal and the receiving terminal.
Enabling the pre-configured resources and releasing other pre-configured resources in the same period:
the terminal receives RRC signaling of the network side equipment for configuring the pre-configured resource, and determines a plurality of continuous resources configured by the network side equipment, wherein the plurality of continuous resources in one pre-configured resource period of the pre-configured resource can be regarded as reserved for the terminal. When the terminal determines that service data arrives, one resource is selected from the pre-configured resources for data reporting, after the network side equipment determines that the terminal uses the pre-configured resources to send a first data packet, the resources at the same position in each pre-configured resource period are enabled, other pre-configured resources in the same pre-configured resource period fail, the network side equipment releases the resources which are not enabled in the pre-configured resources to the terminal, only one enabled resource exists in each pre-configured resource period, and then the terminal can perform data transmission on the enabled resources.
The network side equipment determines the resource position of the terminal for sending the first data packet through the following modes:
the determination method is as follows: determining according to the sending power value of the terminal on the pre-configured resource;
and the network side equipment carries out power detection and determines the resource corresponding to the maximum value of the sending power of the terminal on the plurality of pre-configured resources as the resource for sending the first data packet by the terminal.
Determining a second mode: determining according to the decoded data packet;
the network side equipment receives the report information of the terminal and decodes the report information, the network side equipment can determine the pre-configured resource used by the terminal for sending the first data packet according to the mode of whether the data packet is decoded, and if the network side equipment decodes the data packet, the network side equipment determines the resource used by the terminal for reporting the information at this time as the resource used by the terminal for sending the first data packet.
Determining a third mode: determining according to the indication information reported by the terminal;
the terminal carries the indication information in the data transmission packet, and selects a resource from a plurality of pre-configured continuous resources for data reporting, and the network side equipment takes the resource carrying the data packet containing the indication information sent by the terminal in the plurality of pre-configured continuous resources as the resource for the terminal to send the first data packet.
Wherein, the indication information is carried by the MAC layer as MAC CE, or via a MAC subheader carrying a dedicated indication L CID.
Wherein, for the preconfigured resource type1, as shown in fig. 7, a scene diagram of the provisioning and enabling of the preconfigured resource type1 is shown.
The method comprises the steps that T is a pre-configured resource period, 4 continuous resources exist in one pre-configured resource period, network side equipment takes effect after being configured through RRC signaling for a pre-configured resource type1, when data of a terminal arrives, the terminal selects a resource which is closest to arrival time on the continuous resources to send the data, the network side equipment enables the resource which is the same as the resource which is used for sending the first data packet by the terminal in each pre-configured resource period after determining that the terminal sends the first data packet on the pre-configured resources, other pre-configured resources fail, the network side equipment releases the non-enabled resource in the pre-configured resources to the terminal, and then the terminal conducts data transmission on the enabled resource.
For the preconfigured resource type2, as shown in fig. 8, a scene diagram for configuring and enabling the preconfigured resource type2 for the terminal is shown for the network side device.
Wherein, T is a preconfigured resource period, there are 4 consecutive resources in one preconfigured resource period, and the difference from preconfigured resource type1 is that, for preconfigured resource type2, the network side device needs to activate the resource by activating a PDCCH command of the preconfigured resource after being configured by RRC signaling, the activated resource can be used by the terminal, when the data of the terminal arrives, the resource closest to the arrival time is selected from the activated multiple consecutive resources to send the data, after the terminal sends the resource of the first data packet, the resource at the same resource position in each preconfigured resource period is enabled, other preconfigured resources are disabled, the network side device releases the disabled resource from the multiple preconfigured resources to the terminal, the terminal performs data transmission on the enabled resource, the disabled resource can be configured to other terminals for use, and may be dynamically scheduled to the terminal.
Enabling the pre-configured resources:
after the pre-configured resources are enabled, only one enabled pre-configured resource exists in one pre-configured resource period, the terminal performs data transmission on the enabled pre-configured resource, and if a de-enabling condition configured by the network side device is met, for example, the terminal does not send data on the enabled pre-configured resource for a long time, the enabled resource is de-enabled, that is, the terminal reverts to an activated non-enabled state.
The way in which pre-configured resource type1 and pre-configured resource type2 are disabled is described as follows:
the first disabling mode: enabling the pre-configured resource through a timer or a counter;
the introduction is made by taking a timer as an example: the network side equipment sets the use time length for enabling the pre-configured resource through a timer, before the pre-configured resource is activated and not enabled, the terminal starts or restarts the timer while sending a first data packet on the pre-configured resource, if the terminal does not send data on the pre-configured resource enabled in the subsequent N pre-configured resource periods after the timer reaches the disable time length, the terminal considers that the pre-configured resource is disabled, namely the terminal does not send data through the resource. Assuming that N is 1, fig. 9 is a schematic diagram of a scenario in which a network side device enables a preconfigured resource type1 through a timer. Fig. 9 distinguishes the enabled resource from the data transmission in the enabled resource, where the enabled resource is enabled but the terminal does not perform data transmission on the resource, which is similar to fig. 10 and fig. 11 and is not described in detail below.
When the timer time length reaches the use time length of the preset resource de-enabling, the terminal judges whether the preset resource is to be disabled according to whether the terminal sends data in 1 preset resource period after exceeding the use time length, if the terminal sends data on the enabled resource in the subsequent 1 preset resource period, the preset resource is not disabled, and if the terminal does not have service data in the subsequent preset resource period, namely the terminal does not send data through the preset resource any more, the preset resource is considered to be disabled, namely the terminal is returned to a state with a plurality of continuous resources in the preset resource period.
For another example, if N is a positive integer greater than 1, and N is assumed to be 2, after the terminal determines that the preset use duration is enabled or exceeded, if the terminal does not send data through the enabled resource in the following 2 preset resource periods, the preset resource is considered to be disabled. Fig. 10 is a schematic diagram illustrating a scenario in which a network-side device enables a preconfigured resource type1 through a timer when N is 2. The terminal judges whether to enable the pre-configured resource according to whether the terminal sends data in 2 pre-configured resource periods after the use duration is exceeded, if the terminal sends data on the enabled resource in the subsequent 1 st pre-configured resource period, the pre-configured resource is not enabled, if the terminal does not have service data in the next 2 (the 2 nd pre-configured resource period and the 3 rd pre-configured resource period after T1), namely the terminal does not send data through the pre-configured resource, the pre-configured resource is enabled in the 2 nd pre-configured resource period without using the pre-configured resource to send data, namely the terminal returns to the state with a plurality of continuous resources in one pre-configured resource period.
The network side device may also set, through a counter, the number of used preconfigured resources to be enabled, where the specific execution manner of the counter may refer to the method steps of the timer, and details are not described here.
The disabled use duration or the disabled use number may be specified by a protocol, or the network side device configures the terminal through RRC signaling. For example, the network side device indicates the disabled use duration through RRC signaling configuring the pre-configured resource.
It should be noted that, if the timer reaches the use time for disabling the pre-configured resource or the number of data sent by using the pre-configured resource reaches the use number for disabling the pre-configured resource, if the terminal has a service transmission requirement, the terminal may further continue to send data on the subsequent pre-configured resource until the terminal no longer sends data through the pre-configured resource, and then the terminal considers that the pre-configured resource is disabled. Such as the scenario shown in fig. 11.
The second disabling mode: enabling the pre-configured resource through a disabling command carried by the MAC layer;
the network side equipment receives indication information of the preset resource disabling sent by the terminal, wherein the indication information is an MAC subheader containing L CID indicating the preset resource disabling, or
And the network side equipment enables the pre-configured resource corresponding to the pre-configured resource number through the pre-configured resource number of the pre-configured resource which is carried in the MAC CE and is disabled.
If the L CID in the MAC subheader indicates to disable the pre-configured resource, the value of L CID in the MAC subheader may be a specified value indicating to disable the pre-configured resource in the protocol, and if the value of L CID in the MAC subheader sent by the terminal is the specified value to disable the pre-configured resource, the network side device determines to disable the pre-configured resource configured for the terminal.
If the indication information is a MAC CE, as shown in fig. 12, where a CG (configured grant) index is a preconfigured resource number, the MAC CE may use a MAC sub-header in the above manner, and the MAC sub-header may carry a MAC CE indicating that the corresponding MAC CE is a MAC CE that enables the preconfigured resource, and enable the preconfigured resource corresponding to the preconfigured resource number according to the preconfigured resource number that enables the preconfigured resource and is carried in the MAC CE. Fig. 11 is an example, and the number of bits indicating the pre-configured resource number in the specific MAC CE may be adjusted according to the requirement.
For example, the preconfigured resource number of the preconfigured resource configured for the terminal by the network-side device is 3, the terminal places the preconfigured resource number 3 in the MAC CE1, and carries a MAC CE that indicates to disable the preconfigured resource by using a L CID in the MAC sub-header as MAC CE1, and then the network-side device disables the preconfigured resource corresponding to the preconfigured resource number 3 according to the received indication information carried by MAC CE1, where the preconfigured resource number in the MAC CE1 corresponds to the preconfigured resource that needs to be disabled, and also can determine the preconfigured resource that needs to be disabled by configuring the value of the preconfigured resource number, for example, the value of CG index3 in the MAC CE in fig. 11 is set to 1 (or set to 0) to indicate to disable the preconfigured resource with the preconfigured resource number of 3.
It should be noted that, for the preconfigured resource type1, the network side device enables the preconfigured resource in the following manner:
the disabling mode is three: enabling the pre-configured resource through RRC signaling;
and the network side equipment reconfigures the pre-configured resource with the same pre-configured resource number through RRC signaling, and the enabled pre-configured resource with the same pre-configured resource number is disabled currently.
For example, as shown in fig. 13, the network side device configures a pre-configured resource with a pre-configured resource number of 1 for the terminal, and the terminal sends data on the pre-configured resource, where one pre-configured resource period of the pre-configured resource has one enabled resource. When the network side equipment reconfigures the pre-configured resource with the pre-configured resource number 1 through the RRC signaling again, the resource with the pre-configured resource number 1 is disabled currently, and a new pre-configured resource is determined according to the RRC signaling for reconfiguring the pre-configured resource. The preconfigured resource number is for a set of preconfigured resources, and is distinguished from the resource number of the preconfigured resource in the following, and the resource number is for a resource in a preconfigured resource cycle.
It should be noted that the new pre-configured resource determined by the RRC signaling for reconfiguring the pre-configured resource may be the same as or different from the configuration of the previous pre-configured resource.
Fourthly, releasing the resources of the enabled pre-configured resource type 2;
the first release mode is as follows: releasing the pre-configured resource through a timer or a counter;
taking a counter as an example, the network side device sets the number of used preconfigured resources released by the counter, and the counter is incremented by 1 every time the terminal sends data through the preconfigured resources, and when the number of used preconfigured resources released is reached, the terminal does not send data on the preconfigured resources enabled in the following N preconfigured resource periods, and the terminal considers that the preconfigured resources are released. Assuming that N is 1, fig. 14 is a schematic diagram of a scenario in which a network side device releases a pre-configured resource type2 through a counter.
The duration or the number of the used preconfigured resources released may be specified by a protocol, or the network side device configures the terminal through RRC signaling, or is indicated by a PDCCH order activating the preconfigured resources. For example, the network side device indicates the disabled use duration through RRC signaling configuring the pre-configured resource.
It should be noted that, if the timer duration reaches the usage duration for releasing the preconfigured resource or the number of data sent by using the preconfigured resource reaches the usage number for releasing the preconfigured resource, if the terminal has a service transmission requirement, the terminal may further continue to send data on the subsequent preconfigured resource until the terminal no longer sends data through the preconfigured resource, and then the preconfigured resource is considered to be released.
And a second release mode: releasing the pre-configured resource through a resource releasing command carried by the MAC layer;
the network side equipment releases the pre-configured resource according to the indication information containing the releasing of the pre-configured resource sent by the terminal, the indication information carries with the MAC layer, the network side equipment can carry the disabling command through a single MAC CE, the network side equipment releases the MAC header of L CID of the pre-configured resource according to the carrying indication contained in the MAC CE, or
And the network side equipment releases the pre-configured resource corresponding to the pre-configured resource number through the pre-configured resource number carried in the MAC CE for releasing the pre-configured resource.
And (3) a third release mode: releasing the pre-configured resource through RRC signaling;
and the network side equipment reconfigures the pre-configured resources with the same pre-configured resource number through RRC signaling, and then releases the enabled pre-configured resources with the same pre-configured resource number.
The release mode is four: releasing the pre-configured resource through a new PDCCH order for activating the pre-configured resource;
the network side activates a new resource configuration through a new PDCCH order for activating a pre-configured resource with the same pre-configured resource number, and it can be understood that, when a new pre-configured resource is activated, the pre-configured resource that has been activated and enabled in the pre-configured resource number is released.
For example, as shown in fig. 15, the network side device configures a pre-configured resource type2 resource with a pre-configured resource number of 2 for the terminal, and activates the resource through a PDCCH command, and the terminal sends data on the pre-configured resource, and when the network side device configures a new set of pre-configured resources for the terminal and the pre-configured resource number of the pre-configured resource is also 2, the network side device sends a PDCCH command for activating the newly configured pre-configured resource to the terminal, releases the currently activated and enabled resource with the pre-configured resource number of 2, and determines the new pre-configured resource according to the new PDCCH command for activating the pre-configured resource.
It should be noted that "new" in the PDCCH order for activating the new preconfigured resource may be understood as a PDCCH order sent by the network side device after the PDCCH order for activating the existing preconfigured resource, and the new preconfigured resource determined according to the PDCCH order for activating the new preconfigured resource may be the same as or different from the configuration of the previous preconfigured resource.
And a fifth release mode: releasing the pre-configured resource through a PDCCH order for releasing the pre-configured resource;
and the network side equipment releases the resources of the pre-configured resource type2 configured for the terminal through the PDCCH order carrying the pre-configured resources.
The following is illustrated by way of example:
example 1: configuring and enabling a pre-configured resource type1 based on a Uu port;
a network side:
step 1: the network side equipment sends RRC signaling to the terminal, wherein the RRC signaling comprises part or all of the following: the configuration information of the pre-configured resources, such as the time starting point of the first pre-configured resource, the time-frequency resource position, the transmission format, the number of the pre-allocated continuous resources in one pre-configured resource period, and the like, if the RRC signaling does not contain the indication of the number of the continuous resources, the number of the continuous resources in one pre-configured resource period can be specified by a protocol.
Step 2: the network side equipment receives uplink data sent by the terminal on the pre-configured resource, and determines the pre-configured resource used by the terminal for sending the first data packet through the following modes:
the determination method is as follows: determining a used pre-configured resource according to the maximum value of the transmission power of the terminal;
the network side equipment determines the sending power of the terminal on the pre-configured resource according to the power detection, determines the maximum value of the sending power, namely the sending power of the terminal at the resource is higher than other pre-configured resources, and then the network side equipment determines that the resource is the resource used by the terminal for sending the first data packet. Further, the network side device may also determine the preconfigured resource used by the terminal according to whether the received uplink data can be decoded to obtain a data packet.
Determining a second mode: according to the indication information in the data packet;
the terminal carries indication information in the data packet, the network side equipment receives the data packet reported by the terminal, and determines the pre-configured resource used by the terminal for sending the first data packet according to the indication information carried in the data packet. The indication information is carried in the MAC layer, and may be an individual MAC CE or a MAC subheader.
And step 3: the network side equipment enables resources with the same resource positions as the resources used by the terminal for sending the first data packet in a pre-configured resource period;
the network side device determines the resource position of the terminal sending the first data packet by the above method, and enables the resource at the same position in each preconfigured resource period with the resource receiving the data packet as a starting point, and other resources in the same preconfigured resource period are invalid for the terminal, that is, only one enabled resource exists in one preconfigured resource period, and the invalid resource can be configured for other terminals to use, and can also be dynamically scheduled for the terminal to use.
And 4, step 4: and the network side equipment receives the uplink data of the terminal on the enabled resource in each pre-configured resource period.
