Description

Dynamic authorization-free uplink scheduling method, and terminal device, network device and system applying same
Technical Field
The present application relates to the field of mobile communications, and in particular, to a dynamic grant-free uplink scheduling transmission method, a terminal device, a network device, and a system.
Background
The PUSCH in the NR system of mobile communication is classified into two types: one is a PUSCH sent by a downlink control information scheduling terminal device sent by a network device, and is an uplink service transmission mode of dynamic authorization; one is that the network device semi-statically configures the PUSCH sent by the terminal device, and is an uplink service transmission mode without dynamic authorization.
The eMBB data transmission generally adopts a physical downlink control channel scheduling-based mode. The eBB service data generally has a large information amount and is continuously transmitted within a period of time, and if a scheduling mode without dynamic authorization is adopted, the eBB UE is configured with PUSCH resources in advance, the uplink scheduling flexibility is poor, and the system frequency efficiency is low.
URLLC services generally use a scheduling mode free of dynamic authorization. URLLC traffic is generally characterized by strong burstiness and low traffic. The time delay requires URLLC service of 0.5ms to 1ms level, the time for requesting PUSCH to network equipment and waiting for the network equipment to send authorization scheduling can be saved, and the time delay is effectively reduced.
However, if the network device semi-statically reserves too many uplink resources for the URLLC traffic, the system resource utilization efficiency is low. If the semi-static reserved resources of the network equipment for the URLLC service are too few, the transmission requirement of the URLLC service cannot be met. For the dynamic-grant-free uplink scheduling transmission, after the network device allocates the resources of the dynamic-grant-free uplink scheduling to the terminal device transmitting the URLLC service, it cannot be predicted when the terminal device uses these resources to transmit uplink data, which may cause the waste of the PUSCH resources of the dynamic-grant-free.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and 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 application.
How to configure uplink resources by network equipment, to implement uplink resource multiplexing between a mobile terminal based on dynamic authorization service (e.g. UL eMBB service) and a mobile terminal based on dynamic authorization-free service (e.g. UL URLLC service), so as to achieve the purpose of improving system resource efficiency is a problem that needs 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 are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart of an embodiment of a dynamic-grant-free uplink scheduling transmission method according to the present application. As an embodiment of the method of the present application, the method comprises the following steps:
step 101, a network device sends first indication information to a first terminal device, wherein the first indication information is used for configuring at least one set of dynamic authorization-free PUSCH resources;
the network equipment sends first indication information to the first terminal equipment, wherein the first indication information marks that the number of the dynamic authorization-free PUSCH resources is N; the indication information also identifies a location of the dynamic grant free PUSCH resources.
For example, according to section 6.3.2 of 3gpp ts38.331.v20, the configuration information "ConfiguredGrantConfig" of the PUSCH resource is used to configure the uplink transmission resource without dynamic uplink scheduling grant.
In step 101, the configuration of the dynamic grant-free PUSCH resource for the first terminal device improves the flexibility of uplink data transmission.
It is noted that since the services without dynamic grant data (e.g. URLLC services) are characterized by burstiness, if these resources are reserved for the first terminal device all the time, these resources are in most cases unoccupied, resulting in a waste of resources.
Step 102, the network device sends second indication information to the first terminal device, wherein the second indication information is used for identifying at least one set of reused PUSCH resources; in a set time period, the first terminal equipment transmits uplink services on other PUSCH resources free of dynamic authorization except the reused PUSCH resources;
the reused PUSCH resource is a part of the dynamic-authorization-free PUSCH resource, and is temporarily scheduled to another terminal device (for example, a second terminal device) for dynamically authorizing uplink service transmission.
For example, the network device temporarily schedules a portion of the dynamic grant free PUSCH resources configured for a first terminal device to another second terminal device for the second terminal device to transmit data of the eMBB.
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 affects the data transmission efficiency, the network device sends indication information to the first terminal device, the number of the reused PUSCH resource identified by the indication information is K, and the network device is in a temporary forbidden effective state, wherein K is more than or equal to 1 and less than or equal to N.
It should be noted that the first terminal device is in the temporary forbidden effective state when reusing the PUSCH resource, which affects the flexibility of the dynamic grant-free uplink scheduling to a certain extent. However, when the first terminal device has a data transmission requirement, the first terminal device may select resources from other (N-K) sets of dynamically unlicensed PUSCH resources except for the K sets of reused PUSCH resources, and may still ensure that dynamically unlicensed uplink scheduling data transmission is performed to a certain extent. The network device can control the balance between the flexibility of the uplink service data transmission and the resource utilization efficiency through the frequency sent by the indication information and the value range of K contained in the indication information.
Step 103, the network device sends scheduling information to a second terminal device, and the second terminal device performs uplink service transmission on the reused PUSCH resource according to the scheduling information in the set time period.
Fig. 2 is a flowchart of an embodiment of the dynamic-grant-free uplink scheduling transmission method for a mobile terminal according to the present application.
Step 201, a first terminal device receives first indication information, where the first indication information is used to configure at least one set of dynamic authorization-free PUSCH resources;
in step 201, the first terminal device receives N sets of PUSCH resources configured by the network device. And the first terminal equipment determines resources free of dynamic authorization uplink scheduling according to the first indication information.
Step 202, the first terminal device receives second indication information, wherein the second indication information is used for identifying at least one set of reused PUSCH resources; in a set time period, the first terminal equipment transmits uplink services on other PUSCH resources free of dynamic authorization except the reused PUSCH resources; the reused PUSCH resource is a portion of the dynamic grant-free PUSCH resource.
For example, in step 202, the first terminal device receives second indication information, where the second indication information is used to indicate that K (1 ≦ K ≦ N) sets of resources in the N sets of dynamically unlicensed PUSCH resources are in an invalid state.
And the first terminal equipment determines the resource free of dynamic authorization uplink scheduling according to the first indication information. According to the second indication information, the terminal device can determine which of the configured N sets of dynamic authorization-free PUSCH resources are in an active state within the time from t1 to t2, and which are in a failure state. And selecting the resource for sending the dynamic authorization-free uplink service data from the effective dynamic authorization-free PUSCH.
By the invention, the network equipment can realize uplink resource multiplexing between the terminal equipment based on the dynamic authorization UL eMBB service and the terminal equipment based on the dynamic authorization-free UL URLLC service by configuring the uplink resources, thereby achieving the purpose of improving the resource efficiency of the system.
After receiving the second indication information, the terminal device needs to send a response message 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 configured to the terminal device by the network device are all in an active state. If the network device schedules the K sets of PUSCH resources to other terminal devices for transmitting the eMBB service data, and the first terminal device selects the resources in the K sets of PUSCH resources for transmitting the URLLC service data, the two will generate a conflict, reducing the reliability of the system, and also increasing the delay of the system transmission. Preferably, the embodiment of the dynamic grant-free uplink scheduling method for the terminal device further includes the following steps:
step 202A, the first terminal device sends a response message for confirming that the second indication message is received.
And after receiving the second indication information, the first terminal equipment sends response information aiming at the second indication information to the network equipment.
If the network equipment receives response information aiming at the second indication information sent by the first terminal equipment, the network equipment can be ensured to schedule the K sets of PUSCH resources to the eBB terminal equipment for transmitting the eBB service data. The conflict of uplink transmission of the terminal equipment for sending the eMBB service data and the terminal equipment for sending the URLLC service data on K sets of PUSCH resources is avoided to a certain extent, and the purpose of improving the resource efficiency of the system is achieved.
Fig. 3 is a flowchart of an embodiment of a dynamic grant free uplink scheduling transmission method for a network device according to the present application. The embodiment of the present application further provides a dynamic authorization-free uplink scheduling method, which is used for a network device, and includes the following steps:
step 301, sending 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 a PUSCH resource for the first terminal device, so as 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. And the first terminal equipment determines the resource free of dynamic authorization uplink scheduling according to the first indication information.
Step 302, sending 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; in a set time period, the first terminal equipment only carries out uplink service transmission on other PUSCH resources free of dynamic authorization except the reused PUSCH resource;
the second indication information comprises a parameter for identifying a reused PUSCH resource, wherein the reused PUSCH resource is a part of the dynamic authorization-free PUSCH resource; and within a set time period, stopping the first terminal equipment from carrying out uplink service transmission on the reused PUSCH resource.
For example, second indication information is sent to the first terminal device, where the second indication information is used to indicate that K (1 ≦ K ≦ N) sets of PUSCH resources are in an invalid state. According to the second indication information, the terminal device can determine which of the N sets of configured PUSCH resources are in an effective state within the time from t1 to t2 and which are in an ineffective state, and select the resource for transmitting the dynamic-grant-free uplink scheduling data from the effective PUSCH. The first terminal equipment receives second indication information and stops performing dynamic authorization-free uplink service transmission on the K sets of PUSCH resources;
step 303, sending scheduling information to a second terminal device, where in 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, where the target resource and the K (1 ≦ K ≦ N) set of reuse PDSCH resources have an intersection. The second terminal equipment receives the scheduling information and performs uplink service transmission of dynamic authorization on the target resource indicated by the scheduling information;
that is, the network device permits the second terminal device to use the reused PUSCH resource to perform dynamically authorized uplink service transmission through the scheduling information; and the second terminal equipment at least uses one part of the reused PUSCH resource to carry out dynamically authorized uplink service transmission.
And the second terminal equipment determines the resource of the dynamic authorization uplink scheduling according to the scheduling information. And the network equipment transmits the scheduling information containing at least part of the reused PUSCH resources to other terminal equipment (including but not limited to a second terminal equipment) only within the set time period (t 1-t 2). Other terminal equipment can perform dynamically authorized uplink service transmission on the scheduled L sets of reused PUSCH resources (0< L is less than or equal to K).
Preferably, the embodiment of the dynamic grant-free uplink scheduling method for a network device further includes the following steps:
step 302A, the network device receives the response information from the first terminal device, so as to confirm that the second indication information is received.
Preferably, the embodiment of the dynamic grant-free uplink scheduling method for a network device further includes the following steps:
step 304, in the set time period, receiving uplink service data of the second terminal device on the reused PUSCH resource; and receiving the uplink service data of the first terminal equipment on other PUSCH resources without dynamic authorization except the reused PUSCH resources.
For example, detecting the uplink information of the first terminal device in the PUSCH resources except the K (K is more than or equal to 1 and less than or equal to N) sets of reused PUSCH resources in the N sets of PUSCH resources; and detecting the uplink information of the second terminal equipment on the K (K is more than or equal to 1 and less than or equal to N) set reuse PUSCH resources.
And when the target resource occupies a part of the reused PUSCH resource, detecting the uplink information of the second terminal equipment in the reused PUSCH resource occupied by the target resource.
Fig. 4 is a schematic diagram of a PUSCH resource without dynamic authorization, which shows that a first terminal device is used for PUSCH resource without dynamic authorization for uplink service transmission.
The dynamic-authorization-free PUSCH resources are distributed according to time periods, and each time period comprises at least one time granularity.
For example, according to 3gpp ts38.331.v20, the parameters of the PUSCH resource include a period and a time offset (offset) parameter, and according to the value of the configuration parameter, the terminal device may determine the slot in which the PUSCH is not dynamically authorized. If the first terminal device has a need for uplink data transmission, the uplink data can be transmitted on the resources during the period of validity of the dynamic authorization-free PUSCH.
In any embodiment of the present application, each set of dynamic grant free PUSCH resources is configured with a combination of any of the following parameters:
frequency hopping indication, demodulation reference signal mapping mode configuration, modulation coding mode, uplink control information bearing mode, time and frequency resources occupied by one-time transmission, period, PUSCH repeated transmission times, PUSCH repeated transmission redundancy version mode, HARQ process number, transmission power control parameters, transmission waveform, transmission timing length, transmission time offset and antenna port number.
For example, the S time domain symbols of the nth set of PUSCH resources are symbols satisfying the following condition:
[ system frame number × number of slots per system frame × number of symbols per slot + (current slot index × number of symbols per slot) + current symbol index ] — modulo (time offset parameter × number of symbols per slot + S + N × period configuration) (1024 × number of slots per system frame × number of symbols per slot).
Fig. 5 is a schematic diagram of multiple sets of PUSCH resources exempted from dynamic authorization, which shows that the first terminal device is used for PUSCH resources exempted from dynamic authorization for uplink service transmission.
In the parameters defining one set of no-dynamic-authorization PUSCH resources, any one or more parameters are changed, and another set of no-dynamic-authorization PUSCH resources can be defined.
The dynamic authorization-free PUSCH resources can be divided into a plurality of sets. For example, the network device configures N sets of dynamic-authorization-free PUSCH resources for the terminal device, and by flexibly setting parameters such as the period, the offset value, the occupied symbol position, the number, and the like of the N sets of dynamic-authorization-free PUSCH resources, the terminal device can select one set of dynamic-authorization-free PUSCH resources, which can transmit the uplink data first and has better transmission efficiency, of the N sets of dynamic-authorization-free PUSCH resources when there is an uplink data transmission requirement, so as to ensure the efficiency of the uplink resources and the low delay requirement of service transmission. The network equipment configures at least one configuration parameter among N sets of dynamic authorization-free PUSCH resources for the terminal equipment. As shown in fig. 5, for example, N-3 sets of PUSCH resources are configured for the terminal device.
It should be noted that, in each set of dynamic grant-free PUSCH, in order to improve reliability of scheduling transmission without dynamic grant, in each period range of the dynamic grant-free PUSCH, the terminal device may repeatedly send an uplink transmission block multiple times. The corresponding relation between each resource used for repeated multiple transmissions in one period of the dynamic-grant-free PUSCH and the redundancy version of the uplink data block transmitted on the resource is preset. For example, in the configuration set 1 in fig. 5, the same data block is transmitted 4 times in each period using the resource block including the initial transmission; in the 3 rd configuration in fig. 5, the same data block is transmitted using the resource block including the initial transmission 2 times in each period.
Fig. 6 is a diagram of designated reuse of PUSCH resources. The reused PUSCH resource is a part of the dynamic authorization-free PUSCH resource, and is defined by the set time period in the embodiment of the present application.
For example, the network device (gNB) temporarily schedules a portion of the PUSCH resources configured to the first terminal device (URLLC UE) to the second terminal device (eMBB UE) for the second terminal device to transmit data of the eMBB. If the network equipment sets the resource reuse mode to be effective within the time from t1 to t2, the time that the K sets of configuration resources are in a failure state at the first terminal is t1 to t 2; the time that the K sets of configuration resources are in the effective state at the second terminal is t 1-t 2.
The resource reuse mode is terminated at t2, and the first terminal device can automatically recover the K sets of configuration resources to be in an effective state, so as to avoid dynamic authorization of uplink service transmission.
To practice embodiments of the present application, further. In a mobile communication system, a network device transmits an instruction to a terminal device through control information.
The control information includes first indication information for identifying at least one of the following parameters of each set of dynamically unlicensed PUSCH resources: frequency hopping indication, demodulation reference signal mapping mode configuration, modulation coding mode, uplink control information bearing mode, time and frequency resources occupied by one-time transmission, period, PUSCH repeated transmission times, PUSCH repeated transmission redundancy version mode, HARQ process number, transmission power control parameters, transmission waveform, transmission timing length, transmission time offset and antenna port number.
Preferably, the first indication information further includes index information of each set of the dynamic grant free PUSCH resources.
For example, the configured PUSCH resources are classified into 2 types. And the network equipment configures N sets of PUSCH resources to the terminal equipment. When the configured PUSCH resource is type 1, the terminal device receives the configured RRC signaling, and the configuration information is in an active state all the time. When the configured PUSCH resources are of type 2, after the terminal equipment receives the configured RRC signaling, if the PDCCH scrambled by the CS-RNTI to CRC (cyclic redundancy check bit) is received to activate the resources, the configuration information is in an effective state, and if the PDCCH scrambled by the CS-RNTI is received to deactivate the resources, the configuration information is in a failure 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 configured PUSCH resource is type 1, the terminal device may transmit uplink data on these resources according to the configured RRC signaling. When the configured PUSCH resources are of type 2, the terminal device may transmit uplink data on these resources if the PDCCH receiving the CS-RNTI scrambled CRC check bits activates these resources after receiving the configured RRC signaling.
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, where the second indication information is used to indicate that K (K is greater than or equal to 1 and less than or equal to N) sets of resources are invalid in the N sets of PUSCH resources. And the network equipment temporarily schedules part or all of the PUSCH resources configured to the first terminal equipment to the second terminal equipment for the second terminal equipment to send the eMBB data.
Further, the indication information includes second indication information for identifying the reused PUSCH resource; preferably, the second indication information identifies the reused PUSCH resource with the index information.
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 temporary failure state, that is, in the set time period, for example, t1 to t2, the first terminal device occupies the reused PUSCH resource for a time period from t1 to t2 to perform a function failure of dynamic authorization-free uplink service transmission.
For example, the second indication information includes respective failure or valid states of N sets of dynamically unlicensed PUSCH resources and times t1 to t2 when K sets of reused PUSCH resources are in a failure state. First, the second indication information of the present invention includes respective "invalid" or "valid" states of N sets of dynamically unlicensed PUSCH resources. For example, if N is 3, the second indication information includes 3-bit information, where the 1-bit indicates whether the first set of PUSCH resources is "invalid" or "valid". "spent" is represented by "0" and "active" is represented by "1". The 2 nd bit indicates whether the second set of PUSCH resources is "invalid" or "valid". "failure" is represented by "0", and "valid" is represented by "1", … …, and the second indication information further includes time of K sets of PUSCH failing among N sets of PUSCH resources, which is t1 to t 2. Where t1 may be a transmission time indicating information, and t2 may be one of several preset values. For example, the preset t2 takes four values, namely a1, a2, A3 and a 4. It is indicated in the indication information which of the four values of a1, a2, A3, a4 is t 2. And for K sets of PUSCH resources with the failure of N sets of PUSCH resources, restoring the configuration to be in an effective state at the time t 2.
Preferably, the second indication information is carried by PDCCH or MAC layer signaling.
For example, the second indication information is sent by a physical downlink control channel. If the network device uses a part of the PUSCH resources of type 1 configured to the first terminal device as the reused PUSCH resources, that is, indicates to the first terminal device that the part of the PUSCH resources of type 1 fail within a time period from t1 to t2, although the PUSCH resources of type 1 may be reconfigured by an RRC message, since the resource multiplexing mode is immediate, when dynamically scheduling the multiplexing resources to the second terminal device transmitting the eMBB service, the first terminal device transmitting the URLLC service cannot be indicated in time that the configured PUSCH resources fail within a short period by using the RRC message reconfiguration mode. Therefore, the physical downlink control channel is adopted to send the indication information, so that the aim of dynamically multiplexing uplink resources between the terminal equipment for sending the URLLC service and the terminal equipment for sending the eMBB service can be fulfilled.
If the network device temporarily schedules the part of the PUSCH resources of type 2 configured to the first terminal device to the second terminal device, that is, indicates to the first terminal device that the PUSCH resources of type 2 are partially failed within the time period from t1 to t2, the network device may send the PDCCH of the CS-RNTI scrambling CRC check bits to the first terminal device at time t1 to deactivate these resources, the PUSCH resource configuration information starts to be in a failed state, and the network device sends the PDCCH of the CS-RNTI scrambling CRC check bits at time t2 to activate these resources, and then the PUSCH resource configuration information starts to be in a valid state. Therefore, the physical downlink control channel is adopted to send the indication information, so that the aim of dynamically multiplexing uplink resources between the terminal equipment for sending the URLLC service and the terminal equipment for sending the eMBB service can be fulfilled.
Optionally, the indication information may also be sent by the network device to the terminal device through MAC layer signaling. If the network device indicates to the first terminal device that some of the K sets of PUSCH resources that fail within the time t 1-t 2 are of type 1 and some are of type 2, the network device indicates to the terminal device the state of the PUSCH resources of type 2 through the indication information of the present invention, and the PDCCH scrambled by the CS-RNTI to the CRC check bits indicates the state of the PUSCH resources of type 2, which may cause an excessive signaling burden.
Further preferably, when the second indication information is carried by PDCCH signaling, CRC of the information in the PDCCH is scrambled by X-RNTI; wherein the X-RNTI is an identifier of the first terminal device, and indicates that the PDCCH comprises the second indication information.
The high-level signaling configures different RNTIs for the terminal equipment to identify different downlink control information. The network equipment side uses the RNTI to scramble the CRC part of the channel information and then sends the channel information, and the terminal equipment side uses the RNTI which is configured in advance to descramble so as to correctly decode the downlink control channel line aiming at the terminal equipment side and determine the type of the downlink control information. In this embodiment, the second indication information sent by the network device to the first terminal device is scrambled by an X-RNTI configured to the URLLC terminal device through a high-level signaling, and then sent. And the terminal equipment terminal acquires the indication information of the network equipment after decoding.
