Description

A dynamic authorization-free uplink scheduling method and terminal equipment, network equipment and system applying the same

This application requires a Chinese patent application submitted to the State Intellectual Property Office of China on November 2, 2018, with the application number 201811303200.9 and the invention titled "a dynamic authorization-free uplink scheduling method and terminal equipment, network equipment and system using it" Priority, the entire content of the prior application is incorporated by reference in this application.

Technical field

This application relates to the field of mobile communications, and in particular to a dynamic authorization-free uplink scheduling transmission method, terminal equipment, network equipment, and system.

Background technique

The PUSCH in the NR system of mobile communication is divided into two types: one is the downlink control information sent by the network device to dispatch the PUSCH sent by the terminal device, and is a dynamically authorized uplink service transmission method; the other is the network device semi-statically configured terminal The PUSCH sent by the device is a dynamic authorization-free uplink service transmission method.

The eMBB data transmission usually adopts a method based on physical downlink control channel scheduling. The eMBB service data usually has a large amount of information and is continuously transmitted for a period of time. If the dynamic authorization-free scheduling method is adopted to configure the PUSCH resources for the eMBB UE in advance, the flexibility of uplink scheduling is poor, and the system frequency efficiency is low.

URLLC services generally use a dynamic authorization-free scheduling method. URLLC services usually have the characteristics of strong burstiness and low traffic volume. The delay requires URLLC services at the level of 0.5ms to 1ms, which can avoid the time for requesting PUSCH from the network device and waiting for the network device to send the authorization schedule, thereby effectively reducing the delay.

However, if the network device reserves excessive uplink resources semi-statically for the URLLC service, the system resource usage efficiency is low. If the network device reserves too few resources for the URLLC service semi-statically, it cannot meet the transmission requirements of the URLLC service. For the dynamic authorization-free uplink scheduling transmission, after the network device configures the dynamic authorization-free uplink scheduling resource to the terminal device transmitting the URLLC service, it cannot predict when the terminal device will use these resources to send uplink data, which will cause the dynamic authorization-free PUSCH Waste of resources.

detailed description

In order to make the purpose, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be described clearly and completely in conjunction with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

How network equipment configures uplink resources to realize the multiplexing of uplink resources between mobile terminals based on dynamic authorization services (such as UL eMBB service) and mobile terminals based on non-dynamic authorization services (such as UL URLLC service), so as to improve system resource efficiency The purpose is the problem to be solved by the present invention, and there is no prior art at present.

The technical solutions provided by the embodiments of the present application will be described in detail below in conjunction with the drawings.

FIG. 1 is a flow chart of an embodiment of a dynamic authorization-free uplink scheduling transmission method of the present application. As an embodiment of the method of the present application, it includes the following steps:

Step 101: The network device sends first indication information to the first terminal device, where the first indication information is used to configure at least one set of dynamic authorization-free PUSCH resources;

The network device sends first indication information to the first terminal device, where the first indication information identifies that the number of dynamic authorization-free PUSCH resources is N; the indication information also identifies the location of the dynamic authorization-free PUSCH resources.

For example, according to section 6.3.2 of 3gpp TS38.331.V20, the PUSCH resource configuration information "ConfiguredGrantConfig" is used to configure uplink transmission resources that are not subject to dynamic uplink scheduling authorization.

In step 101, the dynamic grant-free PUSCH resource configured for the first terminal device improves the flexibility of uplink data transmission.

It should be pointed out that since the characteristics of services that do not require dynamic authorization of data (such as URLLC services) are sudden, if these resources are always reserved for the first terminal device, in most cases these resources are unoccupied, resulting in waste of resources .

Step 102: The network device sends second indication information to a first terminal device, where the second indication information is used to identify at least one set of reused PUSCH resources; within a set time period, the first terminal device is dividing Describe the reuse of PUSCH resources other than PUSCH resources to dynamically grant PUSCH resources for uplink service transmission;

The reused PUSCH resource, which is a part of the dynamic grant-free PUSCH resource, is temporarily scheduled to other terminal devices (for example, a second terminal device) for dynamically authorized uplink service transmission.

For example, the network device temporarily schedules a part of the dynamic authorization-free PUSCH resource configured for the first terminal device to another second terminal device for the second terminal device to send eMBB data.

In order to avoid that the first terminal device sends uplink data on the reused PUSCH resource and the uplink transmission conflict of the second terminal device, which affects the data transmission efficiency, the network device sends indication information to the first terminal device, which indicates the reused PUSCH resource The number is K, which is in the state of temporary prohibition, where 1≤K≤N.

It should be noted that the reuse of PUSCH resources by the first terminal device is in a temporarily prohibited effective state, which affects the flexibility of dynamic scheduling without dynamic authorization to a certain extent. However, when there is a data transmission requirement, the first terminal device can select resources from the other (NK) sets of dynamic authorization-free PUSCH resources except for K sets of reused PUSCH resources, which can still guarantee dynamic authorization-free uplink scheduling to a certain extent. data transmission. The network device can control the balance between the flexibility of uplink service data transmission and the efficiency of resource use through the frequency of indication information transmission and the value range of K included in the indication information.

Step 103: The network device sends scheduling information to a second terminal device. During the set time period, the second terminal device performs uplink service transmission on the reused PUSCH resource according to the scheduling information.

FIG. 2 is a flowchart of an embodiment of an application of a dynamic authorization-free uplink scheduling transmission method for a mobile terminal.

Step 201: The first terminal device receives first indication information, where the first indication information is used to configure at least one set of PUSCH resources without dynamic authorization;

In step 201, the first terminal device receives N sets of PUSCH resources configured by the network device. The first terminal device determines a dynamic authorization-free uplink scheduling resource according to the first indication information.

Step 202: The first terminal device receives second indication information, where the second indication information is used to identify at least one set of reused PUSCH resources; within a set time period, the first terminal device removes the reused PUSCH The PUSCH resources free of dynamic authorization other than the resources are used for uplink service transmission; the reused PUSCH resources are part of the PUSCH resources free of dynamic authorization.

For example, in step 202, the first terminal device receives second indication information, which is used to indicate that K (1≤K≤N) of the N sets of dynamic authorization-free PUSCH resources are invalid status.

The first terminal device determines a dynamic authorization-free uplink scheduling resource according to the first indication information. According to the second indication information, the terminal device may determine which of the configured N sets of dynamic authorization-free PUSCH resources are in the valid state and which are in the invalid state within the time period from t1 to t2. In the effective dynamic authorization-free PUSCH, a resource for sending dynamic authorization-free uplink service data is selected.

Through the present invention, the network device can realize the multiplexing of uplink resources between the terminal device based on dynamic authorization UL eMBB service and the terminal device based on dynamic authorization-free UL URLLC service by configuring the uplink resource, so as to achieve the purpose of improving system resource efficiency.

After receiving the second indication information, the terminal device needs to send response information to the network device to notify the network device that the indication information has been received. Otherwise, if the terminal device does not receive the indication information, the N sets of PUSCH resources allocated to the terminal device by the network device are all in an effective state. If the network device schedules K sets of PUSCH resources to other terminal devices for transmitting eMBB service data, and the first terminal device selects the K sets of PUSCH resources for transmitting URLLC service data, the two will conflict. Decreasing the reliability of the system also increases the delay of system transmission. Preferably, the embodiment of a dynamic authorization-free uplink scheduling method for terminal equipment further includes the following steps:

Step 202A: The first terminal device sends response information to confirm receipt of the second indication information.

After receiving the second indication information, the first terminal device sends response information for the second indication information to the network device.

If the network device receives the response information for the second indication information sent by the first terminal device, it can make the network device know that the K sets of PUSCH resources can be scheduled to the eMBB terminal device for transmission of eMBB service data. To a certain extent, the conflict between the uplink transmission of the terminal device that sends the eMBB service data and the terminal device that sends the URLLC service data on the K sets of PUSCH resources is avoided, and the purpose of improving the system resource efficiency is achieved.

FIG. 3 is a flowchart of an embodiment of an application for a dynamic authorization-free uplink scheduling transmission method applied to a network device. An embodiment of the present application also proposes a dynamic authorization-free uplink scheduling method for network devices, which includes the following steps:

Step 301: Send first indication information to a first terminal device, where the first indication information is used to configure at least one set of dynamic authorization-free PUSCH resources;

In step 301, the network device configures PUSCH resources for the first terminal device, which is used to avoid dynamic authorization of uplink service transmission. For example, the first terminal device receives N sets of PUSCH resources configured by the network device. The first terminal device determines a dynamic authorization-free uplink scheduling resource according to the first indication information.

Step 302: Send second indication information to the first terminal device, where the second indication information is used to identify at least one set of reused PUSCH resources; within a set period of time, the first terminal device only removes the Reuse PUSCH resources other than PUSCH resources without dynamic authorization for uplink service transmission;

The second indication information includes a parameter for identifying a reused PUSCH resource, and the reused PUSCH resource is a part of the dynamic authorization-free PUSCH resource; within a set time period, the first terminal device is suspended from the Reuse PUSCH resources for uplink service transmission.

For example, sending second indication information to the first terminal device, where the second indication information is used to indicate that K (1≤K≤N) of the N sets of PUSCH resources are in an invalid state. According to the second indication information, the terminal device can determine which of the configured N sets of PUSCH resources are in the active state and which are in the inactive state between t1 and t2, and choose to send the dynamic authorization-free uplink scheduling data in the effective PUSCH Resources. Receiving, by the first terminal device, the second indication information, and suspending the transmission of the dynamic authorization-free uplink service on the K sets of PUSCH resources;

Step 303: Send scheduling information to the second terminal device. Within a set time period, the scheduling information is used to instruct the second terminal device to perform uplink service transmission on the reused PUSCH resource;

For example, in step 303, the scheduling information is used to instruct the second terminal device to send uplink information on a target resource, and the target resource and the K (1≤K≤N) set reuse PDSCH resource have an intersection. The second terminal device receives the scheduling information, and performs dynamic authorized uplink service transmission on the target resource indicated by the scheduling information;

That is, the network device permits the second terminal device to use the reused PUSCH resources for dynamically authorized uplink service transmission through scheduling information; the second terminal device uses at least a portion of the reused PUSCH resources for dynamically authorized uplink service transmission .

The second terminal device determines dynamically authorized uplink scheduling resources according to the scheduling information. The network device sends scheduling information including at least a part of the reused PUSCH resources to other terminal devices (including but not limited to the second terminal device) only during the set time period (t1 to t2). Other terminal devices can reuse PUSCH resources in the scheduled L sets to perform dynamic authorized uplink service transmission (0 <L≤K).

Preferably, the embodiment of a dynamic authorization-free uplink scheduling method for network devices further includes the following steps:

Step 302A: The network device receives response information from the first terminal device to confirm receipt of the second indication information.

Step 304: Within the set time period, receive the uplink service data of the second terminal device on the reused PUSCH resource; receive the dynamic service authorization-free PUSCH resource other than the reused PUSCH resource. The uplink service data of the first terminal device.

For example, among the N sets of PUSCH resources, PUSCH resources other than the K (1≤K≤N) sets of reused PUSCH resources detect uplink information of the first terminal device; in the K (1≤K≤N ) Detecting the uplink information of the second terminal device on the PUSCH resource.

When the target resource occupies a part of the reused PUSCH resource, the uplink information of the second terminal device is detected in the reused PUSCH resource occupied by the target resource.

FIG. 4 is a schematic diagram of PUSCH resources without dynamic authorization, showing the PUSCH resources used by the first terminal device to transmit uplink services without dynamic authorization.

The PUSCH resources without dynamic authorization are distributed according to a time period, and each time period includes at least one time granularity.

For example, according to 3gpp TS38.331.V20, the parameters of the PUSCH resource include the period and time offset (offset) parameters. According to the configuration parameter values, the terminal device can determine the time slot where the PUSCH is free of dynamic authorization. If the first terminal device has a requirement for uplink data transmission, it may transmit uplink data on these resources during the period when the PUSCH without dynamic authorization is in effect.

In any embodiment of the present application, each set of PUSCH resources without dynamic authorization is configured with any combination of the following parameters:

For example, the S time-domain symbols of the Nth set of PUSCH resources are symbols that satisfy the following conditions:

[System frame number × number of slots in each system frame × number of symbols in each slot + (current slot index × number of symbols in each slot) + current symbol index] = (time offset parameter × per hour Number of symbols in the slot + S + N × period configuration) modulo (1024 × number of slots per system frame × number of symbols per slot).

FIG. 5 is a schematic diagram of multiple sets of dynamic authorization-free PUSCH resources, showing PUSCH resources used by the first terminal device for dynamic authorization-free uplink service transmission.

In defining a set of parameters for dynamic authorization-free PUSCH resources, changing any one or more parameters can define another set of dynamic authorization-free PUSCH resources.

The PUSCH resources without dynamic authorization can be divided into multiple sets. For example, the network device configures N sets of dynamic authorization-free PUSCH resources for the terminal device. By flexibly setting the N sets of dynamic authorization-free PUSCH resources, such as the period, offset value, occupied symbol position and number of parameters, the terminal device can have uplink data When transmitting requirements, choose one of the N sets of dynamic authorization-free PUSCH resources that can transmit the uplink data first and the transmission efficiency is better. The set of dynamic authorization-free PUSCH resources ensures the efficiency of the uplink resources and the low latency requirements for service transmission. The network device configures N sets of dynamic authorization-free PUSCH resources for the terminal device. At least one configuration parameter is different. As shown in FIG. 5 as an example, N = 3 sets of PUSCH resources are configured for the terminal device.

It should be noted that, in each set of dynamic authorization-free PUSCH, in order to improve the reliability of dynamic authorization-free scheduling transmission, the terminal device may repeatedly send one uplink transmission block multiple times within each cycle range of the dynamic authorization-free PUSCH. The correspondence between each resource used for repeated multiple transmissions and the redundant version of the uplink data block sent on the resource within one cycle of the PUSCH without dynamic authorization is preset. For example, in the first set of configurations in Figure 5, the same data block is sent four times using the resource block including the initial transmission in each cycle; in the third set of configurations in Figure 5, the use of the initial transmission is included in each cycle The resource block of is sent the same data block twice.

FIG. 6 is a schematic diagram of designated reused PUSCH resources. The reused PUSCH resource is a part of the dynamic authorization-free PUSCH resource, and is limited by the set time period described in the embodiment of the present application.

For example, the network device (gNB) temporarily schedules the part of the PUSCH resources allocated to the first terminal device (URLLC UE) to the second terminal device (eMBB UE) for the second terminal device to send eMBB data. If the network device sets the resource reuse mode to take effect within the time period from t1 to t2, then the time for the K sets of configuration resources to be in the inactive state at the first terminal is t1 to t2; the K sets of configuration resources are at the second terminal The time in the effective state is t1 ~ t2.

The resource reuse mode ends at time t2, and the first terminal device can restore the K sets of configuration resources to the effective state by themselves, which is used for dynamic authorization-free uplink service transmission.

To implement the embodiments of the present application, further. In mobile communication systems, network devices send instructions to terminal devices through control information.

The control information includes first indication information for identifying at least one of the following parameters of each set of dynamic authorization-free PUSCH resources: frequency hopping indication, demodulation reference signal mapping mode configuration, modulation and coding mode, and bearer uplink Control information method, time and frequency resources occupied by one transmission, period, number of PUSCH repeated transmissions, redundant version mode of PUSCH repeated transmission, number of HARQ processes, transmission power control parameters, transmission waveform, transmission timing length, transmission time offset, The number of antenna ports.

Preferably, the first indication information further includes index information of each set of the PUSCH resources without dynamic authorization.

For example, the configured PUSCH resources are divided into 2 types. The network device allocates N sets of PUSCH resources to the terminal device. When the configured PUSCH resource is type 1, after the terminal device receives the configured RRC signaling, the configuration information is always in the effective state. When the configured PUSCH resource is type 2, after receiving the configured RRC signaling, the terminal device configures this configuration if it receives a PDCCH that scrambles the CRC (cyclic redundancy check bit) with CS-RNTI The information starts to be in an effective state. If a PDCCH scrambled with CS-RNTI to CRC is received to activate these resources, the configuration information starts to be in an invalid state.

Preferably, as an optimized embodiment of the present application, the first indication information is included in RRC signaling or PDCCH.

For example, when the PUSCH resource type 1 is configured, the terminal device can transmit uplink data on these resources according to the configured RRC signaling. When the configured PUSCH resource is type 2, after receiving the configured RRC signaling, the terminal device can transmit uplink data on these resources if it receives the PDCCH with CS-RNTI scrambling CRC check bits to activate these resources.

Further, the control information includes second indication information for identifying the location of the reused PUSCH resource.

For example, the first terminal device receives second indication information, and the second indication information is used to indicate that K (1≤K≤N) sets of the N sets of PUSCH resources are invalid. The network device temporarily schedules part or all of the PUSCH resources configured for the first terminal device to the second terminal device, for the second terminal device to send eMBB data.

Further, the indication information includes second indication information for identifying the reused PUSCH resource; preferably, the second indication information uses the index information to identify the reused PUSCH resource.

Preferably, the second indication information further includes information indicating the set time period. The second indication information identifies that the reused PUSCH resource is in a temporarily invalid state, that is, during the set period of time, for example, t1 to t2, the first terminal device occupies the reused PUSCH resource for a time period from t1 to t2 for dynamic exemption The function of authorized upstream service transmission fails.

For example, the second indication information includes the respective invalid or valid states of N sets of dynamic authorization-free PUSCH resources and the time t1 to t2 when the K sets of reused PUSCH resources are in a disabled state. First of all, the second indication information of the present invention includes N sets of dynamic authorization-free PUSCH resources in the "invalid" or "valid" state. For example, N = 3, then the second indication information includes 3-bit information, where the first bit indicates whether the first set of PUSCH resources is “invalid” or “valid”. "Failure" is represented by "0", and "valid" is represented by "1". The second bit indicates whether the second set of PUSCH resources is "failed" or "valid". "Invalid" is represented by "0", "valid" is represented by "1", ..., further, the second indication information also includes the time of the failed K sets of PUSCHs among the N sets of PUSCH resources is t1 ~ t2 . Where t1 may be the sending time of the indication information, and t2 may be one of several preset values. For example, the preset values of t2 are four values of A1, A2, A3, and A4. The instruction information indicates which of the four values of A1, A2, A3, and A4 is t2. For the K sets of PUSCH resources where N sets of PUSCH resources have failed, the configuration is restored to the “active” state at time t2.

For example, the second indication information is sent by a physical downlink control channel. If the network device uses a part of the type 1 PUSCH resource allocated to the first terminal device as the reused PUSCH resource, it indicates to the first terminal device that part of the type 1 PUSCH resource is invalid within the time period t1 to t2, although it can be done through RRC The PUSCH resources of type 1 are reconfigured. However, because the resource reuse method is immediate, the RRC message reconfiguration method cannot dynamically deliver the multiplexed resources to the second terminal device that sends eMBB services in a timely manner. The first terminal device sending the URLLC service indicates that the configured PUSCH resource becomes invalid in a short period of time. Therefore, using the physical downlink control channel to send the above indication information can meet the purpose of dynamically multiplexing the uplink resources between the terminal device sending the URLLC service and the terminal device sending the eMBB service.

If the network device temporarily schedules the part of the type 2 PUSCH resource allocated to the first terminal device to the second terminal device, that is, indicates to the first terminal device that part of the type 2 PUSCH resource fails within the time period t1 to t2, the network device These resources can be activated by sending the PDCCH of the CS-RNTI scrambled CRC check bit to the first terminal device at time t1 to activate the PUSCH resource configuration information, and the network device sends the CS-RNTI scrambled CRC at time t2 If the PDCCH of the parity bit activates these resources, the PUSCH resource configuration information starts to be in an effective state. Therefore, using the physical downlink control channel to send the above indication information can meet the purpose of dynamically multiplexing the uplink resources between the terminal device sending the URLLC service and the terminal device sending the eMBB service.

Optionally, the indication information may also be sent by the network device to the terminal device through MAC layer signaling. If some of the K sets of PUSCH resources that the network device indicates to the first terminal device that are invalid within the period of t1 to t2 are type 1 and some are type 2, then the network device indicates the type 2 The status of the PUSCH resource, the status of the PUSCH resource of type 2 indicated by the PDCCH scrambled by the CRC check bit through the CS-RNTI will cause excessive signaling burden.

Further preferably, when the second indication information is carried by PDCCH signaling, the CRC of the information in the PDCCH is scrambled with X-RNTI; where X-RNTI is the identifier of the first terminal device, indicating that the PDCCH contains The second indication information.

High-level signaling configures different RNTIs for terminal equipment to identify different downlink control information. The network device uses the RNTI to scramble the CRC part of the channel information before sending. The terminal device uses the pre-configured RNTI descrambling to correctly decode the downlink control channel for itself and determine the type of downlink control information. In this embodiment, the second indication information sent by the network device to the first terminal device is configured to be sent by scrambling to an X-RNTI of the URLLC terminal device through high-layer signaling. After decoding, the terminal device obtains the instruction information of the network device.
