Description

Channel transmission method and device

Technical Field

The present application relates to the field of mobile communications technologies, and in particular, to a channel transmission method and apparatus for processing resource conflicts.

Background

The data volume of the eMBB service is relatively large, the transmission rate is relatively high, and a relatively long time domain scheduling unit is usually adopted for data transmission to improve the transmission efficiency. The generation of data packets of URLLC traffic is bursty and random, and may not generate a data packet for a long period of time or may generate multiple data packets in a short period of time. The data packets of URLLC traffic are in most cases small packets. If the base station allocates resources for the URLLC service in a resource reservation manner, system resources are wasted when there is no URLLC service data, and the short delay characteristic of the URLLC service requires that the data packet is transmitted in a very short time, so that the base station needs to reserve a sufficiently large bandwidth for the URLLC service, resulting in a serious decrease in the utilization rate of the system resources. In view of the burstiness of URLLC service data, in order to improve the utilization rate of system resources, the base station usually does not reserve resources for URLLC service transmission, but adopts a preemption mode.

Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and the accompanying drawings.

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 diagram illustrating channel resource collision of a terminal.

As shown in fig. 1, a first terminal device (UE 1) acquires scheduling information indicating its transmission target channel. In addition, the first terminal device acquires preemption information ("preemption" PDCCH) that can be used by the first terminal device to determine whether the resources of the target channel and the resources of the aggression channel of the second terminal device (UE 2) overlap.

After the first terminal device learns that the target channel conflicts with other encroaching channels, the target channel is stopped being sent, the encroaching channel of the second terminal device can be protected from being interfered by the target channel of the first terminal device, and the reliability of the encroaching channel of the second terminal device is guaranteed. However, the fact that the information carried by the target channel of the first terminal device cannot be transmitted to the network device in time also affects the performance of the first terminal device, and finally affects the transmission efficiency of the system. Under the condition that the target channel carries important uplink information, the terminal equipment always stops sending on the resource which conflicts between the target channel and the preemption channel according to the instruction after acquiring the preemption information, and the problem that the transmission efficiency of the system is too low is solved by the invention.

The scheduling mode has 3 types, the 1 st type, the scheduling information can be scheduled to the terminal device through the physical downlink control channel; in the 2 nd category, the scheduling information may also be configured to the terminal device by a higher layer signaling, which is called "configuration transmission"; in type 3, the scheduling information may also be configured to the terminal device by a higher layer signaling and activated through a physical downlink control channel, which is called "semi-persistent scheduling".

Step 102, obtaining configuration information, where the configuration information is used to indicate whether the preemption information is valid for the type of the first channel.

The configuration information is used for indicating the terminal equipment whether to adjust the first channel according to the preemption information.

Preferably, the first channel is any one of the following channels: PRACH, PUSCH, PUCCH, SRS. Further, the type of the first channel is PUSCH, PUCCI, or SRS, and the scheduling manner satisfies: physical downlink control channel scheduling, semi-persistent scheduling, or configuration transmission. Further preferably, the type of the first channel is PUSCH, the PUSCH does not carry UCI, or the PUSCH carries UCI and does not carry UL-SCH, or the PUSCH carries UCI and carries UL-SCH, the UCI includes at least one of HARQ-ACK and CSI, and the CSI includes one of periodic CSI, semi-persistent CSI, and aperiodic CSI. Or the type of the first channel is PUSCH, and the PUSCH is scheduled by an uplink grant of a random access response, or is scheduled by an uplink grant of a non-random access response, preferably, the type of the first channel is PUSCH, and the PUSCH is used for one of at least two traffic classes, where the two traffic classes may be, for example, eMBB and URLLC. Or, the type of the first channel is PUCCH, the PUCCH carries UCI, and the UCI includes at least one of HARQ-ACK, CSI, and SR information.

Different channel names (PUCCH, PUSCH and SRS), whether UCI is carried, whether UL-SCH is carried, whether uplink grant scheduling of random access response is carried, UCI information used for different service types and carried, different scheduling modes are used, and the different types of first channels are used as long as the different types of first channels are different.

That is, the type of the first channel may be any one of: the physical random access channel PRACH, the PUSCH scheduled by the physical downlink control channel and not carrying UCI, the PUSCH scheduled by the physical downlink control channel and carrying UCI, the PUCCH scheduled by the physical downlink control channel and carrying UCI, the PUSCH scheduled by the physical downlink control channel and carrying UCI and not carrying UL-SCH, the PUSCH scheduled by the physical downlink control channel and carrying UCI and carrying UL-SCH, the PUSCH scheduled by the uplink grant of random access response, the PUSCH scheduled by the uplink grant of non-random access response, the PUSCH for different traffic classes, the SRS scheduled by the physical downlink control channel, the PUSCH scheduled by the semi-persistent scheduling and not carrying UCI, the PUSCH scheduled by the semi-persistent scheduling and carrying UCI, the PUCCH scheduled by the semi-persistent scheduling and carrying UCI, the PUSCH scheduled by the semi-persistent scheduling and not carrying UCI and not carrying UL-SCH, the PUSCH scheduled by the semi-persistent scheduling and not carrying UCI, the PUSCH configured PUSCH transmitted by the configuration and not carrying UCI, the PUSCH transmitted by the PUSCH scheduled by the physical downlink control channel and not carrying UCI, and transmitted by the configuration PUSCH transmitted by the physical downlink control channel and not carrying UCI.

Preferably, the configuration information indicates the types of the first channel carrying UCI and the first channel not carrying UCI independently; for example, corresponding to the first channel not carrying UCI, the configuration information includes a first indication; the configuration information includes a second indication corresponding to the first channel bearer UCI. For example, it may be: the first indication is that the preemption information is valid for the type of the first channel and the second indication is that the preemption information is invalid for the type of the first channel.

Preferably, the configuration information is independently indicated for types of first channels carrying different UCI. For example, the configuration information includes a third indication corresponding to the first channel carrying HARQ-ACK; and the configuration information comprises a fourth indication corresponding to the first channel bearing CSI.

Preferably, the configuration information indicates the types of the first channel carrying the UCI and not carrying the UL-SCH, and the first channel carrying the UCI and carrying the UL-SCH independently. For example, the configuration information includes a fifth indication corresponding to the first channel carrying the UCI and not carrying the UL-SCH; corresponding to the first channel carrying the UCI and carrying the UL-SCH, the configuration information includes a sixth indication.

Preferably, the configuration information of the types of the first channels scheduled by the uplink grant scheduling for the random access response and the uplink grant scheduling for the non-random access response independently indicates, for example, the first channel type scheduled by the uplink grant scheduling for the random access response, the configuration information includes the seventh indication, the first channel type scheduled by the uplink grant scheduling for the non-random access response, and the configuration information includes the eighth indication.

Preferably, the configuration information indicates the types of the first channels used for different service classes independently. For example, when the type of the first channel corresponds to the eMBB service, the configuration information includes a ninth indication, and when the type of the second channel corresponds to the URLLC service, the configuration information includes a tenth indication.

The first to tenth instructions may be applied simultaneously or separately. That is, the technical means of the arrangement of the present application is any combination of the above.

The terminal device obtains configuration information, which may be sent to the terminal device by the network device or determined by the capability of the terminal device itself. Based on the configuration information, the terminal device may determine whether to adjust the first channel based on the "preemption information". The network equipment sends the configuration information to the terminal equipment besides the scheduling information.

Further preferably, the configuration information indicates at least 2 of the scheduling manners for the first channel independently. In the configuration information, the type of the first channel in the 1 st scheduling manner is a first indication; and aiming at the type of the first channel in the 2 nd scheduling mode, the type is a second indication.

Or, the type of the first channel of at least 2 scheduling manners in the scheduling manners uses unified configuration information. In the configuration information, the type of the first channel in the 1 st scheduling manner is a first indication; the type of the first channel in the 2 nd scheduling is also the first indication.

Step 103, acquiring preemption information, where the preemption information includes an indication to perform power adjustment on at least a part of resources in the first channel.

And receiving preemption information, acquiring the instruction of the preemption information by the UE, and determining whether the preemption information is valid according to the configuration information.

The terminal device obtains the preemption information, for example, the preemption information can be obtained by receiving a physical downlink control channel sent by the network device. Regarding the sending manner of the preemption information, preferably, the preemption information is sent by common physical downlink control information of a terminal device group, and corresponding configuration information of at least 2 terminal devices in the terminal device group is different from each other. Or, the preemption information is sent by physical downlink control information dedicated to 1 terminal device.

One solution is that the preemption information is the physical downlink control information common to the terminal device group sent by the network device. The network device groups a plurality of terminal devices into a group in advance. And sending the common physical downlink control information to the terminal equipment in one group. The content indicated by the preemption information may be information about resources associated with the second channel or may be an indication of whether the terminal device stopped the first channel.

Another scheme is that the preemption indication is physical downlink control information of a specific terminal device sent by a network device.

And 104, adjusting or maintaining the transmission power of the at least one part of resources according to the scheduling information, the configuration information and the preemption information.

The adjustment refers to amplification, reduction or switching off.

Adjusting the transmission power of the at least one part of resources according to the scheduling information, the configuration information and the preemption information, comprising: if the configuration information indicates that the preemption information is valid for the type of the first channel, adjusting the transmission power according to the preemption information; maintaining the transmit power if the configuration information indicates that the preemption information is not valid for the type of the first channel.

In any case, the terminal device may determine from the preemption information whether the first channel overlaps with other resources encroaching on the channel (e.g., the second channel).

For example, when the resources of the first channel of the first terminal device and the second channel of the second terminal device overlap, the first terminal device turns off the transmission power of the resource overlapping at least with the second channel in the first channel, so that the interference of the first channel to the second channel of the second terminal device can be avoided, and the reliability of the second channel of the second terminal device can be improved. Similarly, if the first terminal device reduces the transmission power of the resource at least overlapping with the second channel in the first channel, the interference of the first channel to the second channel of the second terminal device can also be reduced, and the reliability of the second channel of the second terminal device is improved. For example, if the preemption information indicates that the first terminal device uses another set of transmit power control parameters to cause the first terminal device to transmit the first channel at a lower transmit power, the reliability of the second channel of the second terminal device is guaranteed. Or, if the first terminal device amplifies the transmission power of the resource at least overlapping with the second channel in the first channel, the interference of the second channel of the second terminal device to the first channel can be overcome to a certain extent, and the reliability of the first channel of the first terminal device is improved. It is similar to the invention that the terminal device adjusts the transmit power of the first channel in dependence on said preemption information.

When the preemption information is sent by the common downlink control information of the terminal group, preferably, the configuration information corresponding to at least 2 terminals in the terminal group is different from each other. In this embodiment, the network device sends, to the first terminal device, an instruction indicating whether the first terminal device stops the first channel according to the preemption information through the configuration information. In the case that the preemption information is the physical downlink control information common to the terminal device group, the network device may configure different configuration information for the terminal devices in the terminal device group. For example, the first terminal device and the third terminal device belong to the same terminal device group. The network device instructs, through the configuration information, the first terminal device to stop the first channel according to the preemption information, and instructs the third terminal device not to stop the first channel according to the preemption information, for example, the transmission power of the first channel may also be increased. Even if the first terminal device and the third terminal device receive the same preemption information, the first terminal device determines that the resources of the second channel and the first channel of the first terminal device are overlapped according to the preemption information, and the first terminal device stops the first channel according to the configuration information. And the third terminal equipment determines that the resources of the second channel and the first channel of the third terminal equipment are overlapped according to the preemption information, but does not stop the first channel according to the configuration information. Therefore, the network equipment can configure whether each terminal equipment stops the first channel according to the preemption information through the configuration information, so that the 'personalized' requirement of each terminal equipment is met, and the overall efficiency of the system is improved.

In this embodiment, the network device sends, to the first terminal device, information about whether the first terminal device stops various types of first channels according to the preemption information through the configuration information, and the network device may provide the terminal device with respective independent configurations for various types of channels. For example, the configuration information indicates that the preemption information is valid for a PUSCH not carrying UCI and indicates that the preemption information is invalid for a PUSCH carrying UCI. For another example, the configuration information indicates that the preemption information is valid for a PUSCH not carrying UCI, indicates that the preemption information is valid for a PUSCH carrying CSI, and indicates that the preemption information is invalid for a PUSCH carrying HARQ-ACK. And for example, the configuration information indicates that the preemption information is effective on a PUSCH carrying the periodic CSI and indicates that the preemption information is ineffective on a PUSCH carrying the aperiodic CSI. And for example, the configuration information indicates that the PUSCH scheduled by the uplink grant of the non-random access response is effective and indicates that the PUSCH scheduled by the uplink grant of the random access response is ineffective. Further, for example, the configuration information indicates that the PUSCH for the first service is valid, the PUSCH for the second service is invalid, and the like. The network equipment indicates whether the preemption information is effective for various channel types through the configuration information, so that the 'personalized' requirements of various channel types sent by the terminal equipment can be met, and the overall efficiency of the system is improved. And for the condition that the target channel carries important uplink information, the terminal equipment indicates that the preemption information is invalid for the channel type through the configuration information. And for the condition that the target channel carries non-important uplink information, the terminal equipment indicates that the preemption information is effective to the channel type through the configuration information. Therefore, when the network equipment can adjust the target channel and the occupied channel through the configuration information and conflict with each other, one channel with more important information is selected from the two channels to be sent, and the problem of low transmission efficiency of the system is solved.

Further preferably, the preemption information comprises resource information for a second channel. In this case, as an embodiment for further optimizing the method of the present invention, the method further comprises the following steps:

step 104A, the terminal device determines whether the resources of the first channel and the second channel are overlapped.

And adjusting or maintaining the resources and/or the transmission power of the first channel according to the scheduling information, the configuration information and the preemption information, wherein the transmission power of at least one part of resources of the first channel is adjusted, and the at least one part of resources comprises overlapped resources of the first channel and the second channel. Specifically, if the resources of the first channel and the resources of the second channel overlap, and the configuration information indicates that the preemption information is valid for the type of the first channel, the transmission power is adjusted according to the preemption information; maintaining the transmit power if the configuration information indicates that the preemption information is not valid for the type of the first channel.

For example, after acquiring the preemption information, the terminal device determines whether the resources of the first channel and the second channel are overlapped. If the first channel is overlapped, the terminal equipment determines whether to adjust the first channel according to the configuration information: if the configuration information indicates that the terminal device does not adjust the first channel after acquiring the preemption information, that is, the preemption information is invalid for the current first channel type, the terminal device does not adjust the first channel. On the contrary, if the configuration information indicates that the terminal device adjusts the first channel after acquiring the preemption information, that is, the preemption information is valid for the current type of the first channel, the terminal device adjusts the first channel.

FIG. 3 is a flow chart of an embodiment of the method of the present invention for a network device;

as an embodiment of the second aspect of the present application, a channel transmission method is further provided, where the channel transmission method is used for a network device, and includes the following steps:

step 201, sending first scheduling information, where the first scheduling information is used to instruct a first terminal device to send a first channel;

the type of the first channel is any one of the following types: PRACH, PUSCH, PUCCH, SRS.

For example, the type of the first channel is PUSCH, PUCCH, or SRS, and the scheduling manner satisfies: physical downlink control channel scheduling, semi-persistent scheduling, or configuration transmission. Preferably, the configuration information is independently indicated for at least 2 of the scheduling manners of the first channel.

For another example, the type of the first channel is PUSCH, and the PUSCH does not carry UCI; or, the PUSCH carries UCI, and the UCI includes at least one of HARQ-ACK and CSI. Preferably, the first channel type not carrying UCI and the first channel type carrying UCI are respectively and independently indicated by the configuration information.

For another example, the type of the first channel includes a PUCCH, where the PUCCH carries UCI, and the UCI includes at least one of HARQ-ACK, CSI, and SR. Optimally, the configuration information is independently indicated for types of first channels carrying different UCI.

The embodiment of other configuration information is described in step 102 of this application, and is not described herein again.

Step 202, sending second scheduling information, where the second scheduling information is used to instruct a second terminal device to send a second channel.

Step 203, sending configuration information, where the configuration information is used to indicate whether the preemption information is valid for the type of the first channel.

The preemption information includes an indication to power adjust at least a portion of resources in the first channel. The preemption information comprises resource information for the second channel. The adjustment refers to amplification, reduction or switching off.

Preferably, the preemption information is sent by the common physical downlink control information of the terminal equipment group. The corresponding configuration information of at least 2 terminal equipments in the terminal equipment group is different from each other.

And 204, receiving a first channel according to the first scheduling information, the configuration information and the preemption information.

In step 204: and if the resources of the first channel and the resources of the second channel are overlapped, and the configuration information indicates that the preemption information is valid for the type of the first channel, determining that the first terminal equipment adjusts the transmission power of at least a part of the resources in the first channel.

And the network equipment receives the data according to the mode that the first terminal equipment adjusts the transmission power of at least one part of resources in the first channel.

When the base station receives data of the terminal, it is expected what resources and how much power the terminal uses to transmit. The base station sends the configuration information and the preemption information to the terminal equipment, predicts the response of the terminal according to the protocol and receives signals according to the behavior corresponding to the terminal.

And if the resources of the first channel and the resources of the second channel are overlapped, but the configuration information indicates that the preemption information is invalid for the type of the first channel, determining that the first terminal equipment maintains the transmission power of the first channel.

The network device receives the data in a manner that the first terminal device maintains the transmission power of at least a part of resources in the first channel.

Various types of scenarios for various first channels are described below:

case 1, the first channel is the physical random access channel PRACH.

The PRACH is an access channel when the terminal device starts to initiate a call, and after receiving the PRACH response message, the terminal device sends an RRC connection request message on the PRACH channel according to the indication information of the network device, and completes RRC connection establishment with the network device. Or, if the uplink of the terminal equipment is out of synchronization, the terminal equipment acquires a Timing Advance (TA) by sending a Physical Random Access Channel (PRACH). Or, if the terminal device has uplink data to send but does not have SR resources, the terminal device requests uplink scheduling or the like from the network device through the PRACH.

If the configuration information indicates that the first terminal device stops the PRACH which is currently performed or is to be transmitted after acquiring the preemption information, the time delay of the uplink connection of the first terminal device and the time delay of the uplink data transmission of the first terminal device are affected. However, for the second terminal device, the transmitted second channel can be free from the interference of the first channel of the first terminal device, and the reliability of the second channel of the second terminal device is improved. If the configuration information indicates that the PRACH which is currently performed or is to be transmitted is not turned off after the first terminal device acquires the preemption indication, the PRACH channel will interfere with the second channel of the second terminal device, and the reliability of the second channel of the second terminal device will be difficult to be ensured.

In this embodiment, the network device may instruct, through the configuration information, the terminal device to stop or not stop sending the PRACH channel when the terminal device acquires the preemption information and determines that there is a collision between resources of the PRACH channel to be sent or already being sent and resources of other channels. If the terminal equipment is configured not to stop the first channel, the PRACH performance of the terminal equipment can be ensured, the access performance and the uplink data transmission performance of the terminal equipment are ensured, but the reliability of the second channel cannot be ensured. If the terminal device is configured to stop the first channel, the reliability of the second performance can be guaranteed, but the transmission efficiency of the first terminal device is affected. When the preemption information is the physical downlink control information common to the terminal device group, the network device may allocate different configuration information to the terminal devices in the terminal device group. The performance of the first channel and the second channel of each terminal device is effectively controlled, the overall efficiency of the system is not affected, and the problem that the transmission efficiency of the system is too low for stopping the transmission of the PRACH channel after the terminal device acquires the preemption information is solved. Or, the network device may configure the terminal device with information indicating whether the preemption information is valid for each channel type, effectively control the channel transmission priority sequence when the occupied channels of each terminal device conflict, and solve the problem of too low system transmission efficiency caused by channel preemption.

Case 2, the first channel is a PUSCH scheduled by a physical downlink control channel and carrying no UCI, or the first channel is a PUSCH semi-persistently scheduled and carrying no UCI, or the first channel is a PUSCH configured to transmit and carrying no UCI.

There are 3 ways for PUSCH scheduling, one is physical downlink control channel scheduling, one is configured to transmit, or one is semi-persistent scheduling. The configured and sent PUSCH is, for example, time-frequency resources, DMRS resources, used MCS tables and the like configured to the terminal equipment by RRC signaling about the PUSCH. For example, 3gpp TS 38.214v5.1.0, "configured grant" of type 1 described in section 6.1, the terminal device determines to configure the transmitted PUSCH according to the rrc-configurable uplink grant in the higher layer signaling configurable grant configuration. The PUSCH of the "semi-persistent scheduling" is, for example, after the resource of the PUSCH of the terminal device is configured by the RRC signaling, the network device activates the configuration of the PUSCH resource by the RRC signaling through the physical downlink control channel. For example, "configured grant" of type 2 described in section 6.1 of 3gpp TS 38.214v5.1.0, the terminal device determines the semi-persistently scheduled PUSCH according to the higher layer signaling configuredtconfirm, where the signaling does not include rrc-configurable uplinklankgrant information, and after receiving the higher layer signaling, the terminal device transmits the semi-persistently scheduled PUSCH during the activation of the physical downlink control channel.

In addition, the information carried by the PUSCH includes at least one of UL-SCH (uplink shared channel) and UCI. When the PUSCH does not carry UCI, only UL-SCH, i.e. uplink traffic data, is included therein.

If the first channel is a PUSCH not carrying UCI and the PUSCH carries uplink service data with higher delay requirement, the uplink service data transmission delay characteristic of the first terminal device will be affected if the configuration information indicates that the first terminal device stops performing or is about to transmit after acquiring the preemption information and the PUSCH not carrying UCI is not carried. On the other hand, if the first terminal device stops the ongoing or upcoming PUSCH transmission, for the second terminal device, the second channel transmitted by the second terminal device may be free from the interference of the first channel of the first terminal device, which has an effect of improving the reliability of the second channel of the second terminal device.

If the configuration information indicates that the first terminal device does not stop the ongoing or upcoming PUSCH carrying the UCI after acquiring the preemption information, the PUSCH channel will interfere with the second channel of the second terminal device, and the reliability of the second channel of the second terminal device will be difficult to be ensured.

In this embodiment, the network device may instruct, through the configuration information, the terminal device to stop or not stop sending the PUSCH channel when acquiring the preemption information and determining that there is a collision between resources of the PUSCH channel that is about to be sent or is already being sent and does not carry UCI and other second channels. If the terminal equipment is configured not to stop the first channel, the time delay performance of the PUSCH of the terminal equipment can be ensured, but the reliability of the second channel cannot be ensured. If the terminal device is configured to stop the first channel, the reliability of the second performance can be guaranteed, but the transmission efficiency of the first terminal device will be affected. When the preemption information is the physical downlink control information common to the terminal device group, the network device may allocate different configuration information to the terminal devices in the terminal device group. The performance of the first channel and the second channel of each terminal device is effectively controlled, the overall efficiency of the system is not affected, and the problem that the transmission efficiency of the system is too low for stopping the transmission of the PUSCH channel after the terminal device acquires the preemption information is solved. Or, the network device may configure information on whether the preemption information is valid for various channel types for the terminal device, control the channel transmission priority sequence when the preemption information conflicts for each terminal device, and solve the problem of too low system transmission efficiency caused by channel preemption.

It should be noted that, for the PUSCH scheduled by the physical downlink control channel and not carrying the UCI, the PUSCH semi-persistently scheduled and not carrying the UCI, and the PUSCH configured to be transmitted and not carrying the UCI, the network device may respectively and independently use the three types as the first channel, and configure, through the respectively and independently indicating information, whether the terminal device stops the first channel according to the preemption information; alternatively, the network device may also use two or three of the three types as the same first channel, and configure, through the unified indication information, whether the terminal device stops the first channel according to the preemption information. For example, the first channel is sometimes a PUSCH scheduled by a physical downlink control channel and not carrying UCI, and the terminal device determines, according to the configuration information, whether the terminal device stops scheduling by the physical downlink control channel and does not carry the PUSCH of UCI according to the preemption information; the first channel is sometimes a PUSCH which is semi-persistently scheduled and does not carry UCI, and the terminal equipment determines whether the terminal equipment stops the PUSCH which is semi-persistently scheduled and does not carry UCI according to the preemption information or not according to the configuration information; and the terminal equipment determines whether the terminal equipment stops configuration according to the preemption information and does not carry the PUSCH of the UCI according to the configuration information. Alternatively, the first channel does not distinguish whether the PUSCH not carrying UCI is scheduled, semi-persistently scheduled, or configured to be transmitted through a physical downlink control channel. The configuration information is used for configuring whether the terminal equipment stops carrying the PUSCH of the UCI according to the preemption information. According to the configuration information, the terminal equipment can simultaneously know whether to stop scheduling through the physical downlink control channel and not bear the PUSCH of the UCI, semi-persistent scheduling and not bear the PUSCH of the UCI and configure the PUSCH which is sent and not bears the UCI according to the preemption information.

Case 3, the first channel is a PUSCH scheduled by a physical downlink control channel and carrying UCI, or the first channel is a PUSCH semi-persistently scheduled and carrying UCI, or the first channel is a PUSCH configured to transmit and carrying UCI. The UCI comprises at least one of HARQ-ACK and CSI.

If the first channel is a PUSCH for carrying UCI and the PUSCH carries uplink service data with higher delay requirement, if the configuration information indicates that the first terminal device stops the ongoing or upcoming PUSCH transmission after acquiring the preemption indication, the uplink service data transmission delay characteristic of the first terminal device will be affected. Or, even if the PUSCH carries uplink service data that is not subject to a relatively high latency requirement, if the configuration information indicates that the first terminal device stops performing or is about to send the PUSCH carrying the UCI after acquiring the preemption indication, the latency characteristic of the downlink or uplink service data of the first terminal device will be affected. For example, if the UCI includes HARQ-ACK information, the first terminal device cancels the PUSCH carrying the HARQ-ACK information, which results in the network device having to retransmit all PDSCHs associated with the HARQ-ACK codebook, resulting in reduced system efficiency. If the UCI includes CSI information, the first terminal device cancels the PUSCH carrying the HARQ-ACK information, which may cause the network device not to obtain the channel state information fed back by the first terminal device in time, resulting in low PDSCH scheduling accuracy and low efficiency. On the other hand, however, if the first terminal device stops the ongoing or upcoming PUSCH transmission, the second channel transmitted by the second terminal device may be free from the interference of the first channel of the first terminal device for the second terminal device, which has the effect of improving the reliability of the second channel of the second terminal device. If the terminal equipment is configured not to stop the first channel, the time delay performance of the PUSCH of the terminal equipment, the transmission efficiency of the PDSCH related to the UCI and the performance in the scheduling accuracy can be ensured, but the reliability of the second channel cannot be ensured. If the terminal device is configured to stop the first channel, the reliability of the second performance can be guaranteed, but the transmission efficiency of the first terminal device will be affected. When the preemption information is the physical downlink control information common to the terminal device group, the network device may allocate different configuration information to the terminal devices in the terminal device group. The performance of the first channel and the second channel of each terminal device is effectively controlled, the overall efficiency of the system is guaranteed not to be affected, and the problem that the transmission efficiency of the system is too low for stopping the transmission of the PUSCH with the UCI after the terminal devices acquire the preemption information is solved. Or, the network device may configure information on whether the preemption information is valid for various channel types for the terminal device, effectively control the channel transmission priority sequence when the occupied channels of the terminal devices conflict, and solve the problem of too low system transmission efficiency caused by channel preemption.

Similarly, there are three corresponding ways for the scheduling types of the PUSCH for scheduling and carrying UCI through the physical downlink control channel, the PUSCH for scheduling and carrying UCI through the semi-persistent scheduling, the PUSCH for configuring transmission and carrying UCI, and the PUSCH: physical downlink control channel scheduled, configuration transmitted and semi-persistent scheduled. The UCI may be HARQ-ACK only, CSI only, or both HARQ-ACK and CSI, the CSI including one of periodic CSI, semi-persistent CSI, and aperiodic CSI.

It should be noted that, for the PUSCH scheduled and carrying UCI through the physical downlink control channel, the PUSCH semi-persistently scheduled and carrying UCI, and the PUSCH configuring and transmitting and carrying UCI, the network device may respectively and independently use the three types as the first channel, and configure, through the respectively and independently configuration information, whether the terminal device stops the first channel according to the preemption information; or, the network device may also use two or three of the three types as the same first channel, and configure, through unified configuration information, whether the terminal device stops the first channel according to the preemption information. For example, the first channel is scheduled by the physical downlink control channel and carries the PUSCH of the UCI, and the terminal device determines, according to the configuration information, whether the terminal device stops scheduling by the physical downlink control channel and carries the PUSCH of the UCI according to the preemption information; for another example, the first channel is a PUSCH for semi-persistent scheduling and carrying UCI, and the terminal device determines, according to the configuration information, whether the terminal device stops the PUSCH for semi-persistent scheduling and carrying UCI according to the preemption information; for another example, the first channel is a PUSCH configured and sent and carrying UCI, and the terminal device determines, according to the configuration information, whether the terminal device stops configuring and carrying the PUSCH of UCI according to the preemption information.

Or, the first channel does not distinguish whether the PUSCH carrying the UCI is scheduled through a physical downlink control channel, semi-persistent scheduling, or configuration transmission. The configuration information is used for indicating whether the terminal equipment stops bearing the PUSCH of the UCI according to the preemption information. According to the configuration information, the terminal equipment can simultaneously know whether to stop scheduling through the physical downlink control channel and bear the PUSCH of the UCI, semi-persistent scheduling and bear the PUSCH of the UCI and configure the PUSCH which is sent and bears the UCI according to the preemption information.

It should be noted that the UCI may have only HARQ-ACK, only CSI, or both HARQ-ACK and CSI. The network equipment may respectively and independently indicate whether the terminal equipment stops the first channel according to the preemption information aiming at different UCIs; or, the network device indicates the terminal device whether to stop the first channel according to the preemption information in a unified way aiming at different UCIs. For example, the first channel is a PUSCH scheduled by a physical downlink control channel and carrying UCI, and the terminal device determines, according to the configuration information, whether to stop scheduling by the physical downlink control channel and carrying the HARQ-ACK according to the preemption information; for another example, the first channel is a PUSCH scheduled through a physical downlink control channel and carrying UCI, and the terminal device determines, according to the configuration information, whether the terminal device stops scheduling through the physical downlink control channel and carries the CSI according to the preemption information; the first channel is sometimes a PUSCH which is semi-persistently scheduled and carries HARQ-ACK, and the terminal equipment determines whether to stop the PUSCH which is semi-persistently scheduled and carries HARQ-ACK according to the preemption information according to configuration information; for another example, the first channel is a semi-persistent scheduled PUSCH carrying CSI, and the terminal device determines, according to the configuration information, whether the terminal device stops the semi-persistent scheduled PUSCH carrying CSI according to the preemption information; for another example, the first channel is a PUSCH configured and transmitted and carrying HARQ-ACK, and the terminal device determines, according to the configuration information, whether to stop configuring and carrying the HARQ-ACK according to the preemption information. For another example, the first channel is a PUSCH configured and transmitted and carrying CSI, and the terminal device determines, according to the configuration information, whether the terminal device stops configuring and carrying the PUSCH of CSI according to the preemption information.

Or, the first channel does not distinguish whether the PUSCH carrying the UCI is scheduled, semi-persistently scheduled, or configured to be transmitted through a physical downlink control channel, or whether the UCI is HARQ-ACK, CSI, HARQ-ACK, or CSI. The configuration information is used for indicating whether the terminal equipment stops bearing the PUSCH of the UCI according to the preemption information. According to the configuration information, the terminal equipment can simultaneously know whether to stop scheduling through the physical downlink control channel and bear the PUSCH of the UCI, semi-persistent scheduling and bear the PUSCH of the UCI and configure the PUSCH which is sent and bears the UCI according to the preemption information.

Or, the first channel does not distinguish whether the PUSCH carrying the UCI is sent by physical downlink control channel scheduling, semi-persistent scheduling or configuration, but distinguishes whether the UCI is HARQ-ACK, CSI, HARQ-ACK or CSI. For example, the first channel is a PUSCH for carrying HARQ-ACK, and the terminal device determines, according to the configuration information, whether the terminal device stops carrying the PUSCH for HARQ-ACK according to the preemption information; the first channel is sometimes a PUSCH carrying CSI, and the terminal equipment determines whether the terminal equipment stops carrying the PUSCH carrying CSI according to the preemption information or not according to the configuration information; for another example, the first channel is a PUSCH for carrying HARQ-ACK and CSI, and the PUSCH for carrying HARQ-ACK and CSI is not stopped;

if there are two UCIs, and the condition that whether the terminal equipment configured by the configuration information stops bearing the PUSCHs of different UCIs according to the preemption information is different, the terminal equipment does not stop the PUSCHs according to the preemption information. For example, the terminal device determines, according to the configuration information, that the terminal device stops carrying the PUSCH of the HARQ-ACK according to the preemption information, but the terminal device does not determine, according to the configuration information, that the terminal device stops carrying the PUSCH of the CSI according to the preemption information. And when the first channel is the PUSCH carrying the HARQ-ACK and the CSI, the terminal equipment does not stop the PUSCH according to the preemption information.

Optionally, for PUSCHs used for different service types, the network device may configure, through separate indication information, whether the terminal device stops the first channel according to the preemption information. Different service classes are e.g. eMBB and URLLC. Different service types have different requirements on the reliability and/or time delay characteristics of service transmission. And the network equipment respectively configures independent configuration information for the PUSCHs of different service types. And the terminal equipment determines whether to adjust the transmission power of at least one part of resources after acquiring the preemption information according to which service type the PUSCH being transmitted serves, the scheduling information and the preemption information. Therefore, the network equipment can integrally control the results of resource sharing, avoidance and the like among different services of each terminal equipment, and the requirement of the integral efficiency of the system is met.

Optionally, the uplink grant scheduling for the PUSCH is in a random access response, and the uplink grant scheduling for the PUSCH is in a non-random access response. The network device may configure, through the respective independent indication information, whether the terminal device stops the first channel according to the preemption information. In the random access process of the terminal equipment, the network equipment schedules the terminal equipment to send PUSCH in response information of the access request of the terminal equipment. And receiving the PUSCH (physical uplink shared channel) which is responded by random access and scheduled by an uplink grant, wherein the PUSCH carries important information of whether random access is successful or not, such as an RRC connection request, RRC connection configuration completion, an RRC reestablishment request and the like. Therefore, whether the PUSCH scheduled by the uplink grant of the random access response is correctly transmitted will affect the success or failure of the random access procedure of the terminal device or the delay. In this way, the network device may configure, through the respective independent indication information, whether the terminal device stops the PUSCH scheduled by the uplink grant for the random access response according to the preemption information and whether the terminal device stops the PUSCH scheduled by the uplink grant for the non-random access response according to the preemption information, so as to meet the requirement of the overall efficiency of the system.

Optionally, the PUSCH may carry the UCI, or may not carry the UCI. When the PUSCH carries the UCI, the PUSCH can carry the UL-SCH at the same time or not. If the PUSCH carries the UCI but not the UL-SCH at the same time, the UCI often includes aperiodic CSI that the network device schedules for the terminal device to transmit. The aperiodic CSI scheduled by the network device may have an important influence on subsequent downlink scheduling of the terminal device, and if the terminal device stops carrying UCI but does not carry the PUSCH of the UL-SCH according to the preemption information, the accuracy of downlink scheduling of the terminal device is inevitably influenced, thereby affecting the system efficiency. Therefore, the decision right of whether the terminal device stops carrying the UCI according to the preemption information but does not carry the PUSCH of the UL-SCH needs to be grasped by the network device, so that the network device can plan which channels of which UEs are effective for the preemption information and which channels of which UEs are ineffective for the preemption information as a whole, and the requirement of the overall efficiency of the system is met. Optionally, the network device may configure, through the respective independent indication information, whether the terminal device stops carrying the PUSCH of the UCI according to the preemption information, and whether the terminal device stops carrying the PUSCH of the UCI according to the preemption information. Optionally, the network device may configure, through the respective independent indication information, whether the terminal device stops carrying the UCI and carries the PUSCH of the UL-SCH according to the preemption information, and whether the terminal device stops carrying the UCI and does not carry the PUSCH of the UL-SCH according to the preemption information. Optionally, according to different types of UCI, the network device may configure, through separate indication information, whether the terminal device stops carrying various types of UCI according to the preemption information and carries a PUSCH of the UL-SCH; and the network equipment can configure whether the terminal equipment stops bearing various UCI types and does not bear the PUSCH of the UL-SCH according to the preemption information through respectively independent indication information. The UCI types described herein include: HARQ-ACK, CSI. The CSI includes one of periodic CSI, semi-persistent CSI, and aperiodic CSI. In case 4, the first channel is a PUCCH scheduled based on a physical downlink control channel, a semi-persistent PUCCH, or a PUCCH configured for transmission.

The PUCCH is used to transmit Uplink Control Information UCI (Uplink Control Information). The content of the UCI includes at least one of Channel State feedback CSI (Channel State Information), HARQ-ACK (including ACK and NACK), scheduling Request SR (Scheduling Request).

There are three types of PUCCH transmission: scheduled based on physical downlink control channel, semi-persistent, or configuration transmission. The physical downlink control channel scheduling refers to a method for indicating the resources of the corresponding PUCCH when the network device transmits scheduling information of the PDSCH. The semi-persistent PUCCH refers to a PUCCH related to the semi-persistently scheduled PDSCH that is indicated by the network device when the semi-persistently scheduled PDSCH is activated. Configuring the transmitted PUCCH refers to a persistent periodic PUCCH configured through higher layer signaling.

If the configuration information indicates that the first terminal device stops the ongoing or upcoming PUCCH carrying the UCI after acquiring the preemption indication, the delay characteristic of the downlink or uplink service data of the first terminal device will be affected. For example, if the UCI includes HARQ-ACK information, the first terminal device cancels the PUSCH carrying the HARQ-ACK information, which results in the network device having to retransmit all PDSCHs associated with the HARQ-ACK codebook, resulting in reduced system efficiency. If the UCI comprises CSI information, the first terminal equipment cancels the PUSCH carrying the HARQ-ACK information, so that the network equipment cannot timely obtain the channel state information fed back by the first terminal equipment, and the PDSCH scheduling accuracy and the PDSCH scheduling efficiency are low; if the UCI includes SR information, the first terminal device has to delay requesting uplink scheduling from the network device, causing too large a delay in uplink traffic transmission. On the other hand, however, if the first terminal device stops the PUCCH being transmitted or about to be transmitted, the second channel transmitted by the second terminal device may be free from the interference of the first channel of the first terminal device for the second terminal device, which may improve the reliability of the second channel. If the terminal equipment is configured not to stop the first channel, UCI transmission of the terminal equipment can be ensured, and the transmission efficiency and scheduling accuracy of the PDSCH related to the UCI can be ensured. But the reliability of the second channel cannot be guaranteed. When the preemption information is the physical downlink control information common to the terminal device group, the network device may allocate different configuration information to the terminal devices in the terminal device group. The performance of the first channel and the second channel of each terminal device is effectively controlled, the overall efficiency of the system is guaranteed not to be affected, and the problem that the transmission efficiency of the system is too low for stopping the transmission of the PUSCH with the UCI after the terminal devices acquire the preemption information is solved. Or, the network device may configure the terminal device with information indicating whether the preemption information is valid for each channel type, control the channel transmission priority sequence when the occupied channels of each terminal device conflict, and solve the problem of low system transmission efficiency caused by channel preemption.

It is noted that the UCI may be at least one of HARQ-ACK, CSI, and SR. The network device may respectively and independently configure, for different UCIs, whether the terminal device stops the first channel according to the preemption information; or, the network device may also configure, for different UCI, whether the terminal device stops the first channel according to the preemption information.

In case 5, the first channel is an SRS scheduled by a physical downlink control channel, a semi-persistently scheduled SRS, or a configured SRS to be transmitted.

The network device uses the SRS to estimate the position of the terminal device. The network device can obtain 'uplink channel state estimation' according to the SRS, allocate resource blocks with good instantaneous channel states to uplink PUSCH transmission of the terminal device, and simultaneously can select different transmission parameters (such as instantaneous data rate), and select different parameters related to corresponding uplink multi-antenna transmission (namely used for 'uplink frequency selective scheduling'), and the like. SRS can also be used to estimate uplink timing and to estimate downlink channel quality using channel symmetry under the assumption of mutual benefit of downlink/uplink channels (especially TDD). The SRS has an SRS transmitted by "configuration" configured by RRC.

If the first channel is the SRS, if the configuration information indicates that the first terminal device stops the ongoing or upcoming SRS after acquiring the preemption indication, the network device will be affected to normally acquire the channel state of the first terminal device, estimate uplink timing, acquire a downlink channel state, and the like. On the other hand, however, if the first terminal device stops the ongoing or upcoming SRS transmission, the second channel transmitted by the second terminal device may be free from the interference of the first channel of the first terminal device for the second terminal device, which has an effect of improving the reliability of the second channel of the second terminal device.

If the terminal device is configured not to stop the first channel, it can be ensured that the network device normally acquires the channel state of the first terminal device, estimates the uplink timing, and acquires the downlink channel state condition, but the reliability of the second channel cannot be ensured.

When the preemption information is the physical downlink control information common to the terminal device group, the network device may allocate different configuration information to the terminal devices in the terminal device group. The performance of the first channel and the second channel of each terminal device is effectively controlled, the overall efficiency of the system is guaranteed not to be affected, and the problem that the transmission efficiency of the system is too low for stopping the transmission of the PUSCH with the UCI after the terminal devices acquire the preemption information is solved. Or, the network device may configure information on whether the preemption information is valid for various channel types for the terminal device, effectively control the channel transmission priority sequence when the occupied channels of the terminal devices conflict, and solve the problem of too low system transmission efficiency caused by channel preemption.

Fig. 4 is a block diagram of an embodiment of the apparatus of the present invention.

As an embodiment of the third aspect of the present application, there is further provided a channel transmission apparatus, configured to be used in the method described in any one of the embodiments of the present application. The channel transmission device comprises a downlink receiving module 1 and a control module 2.

The method comprises the steps that terminal equipment obtains scheduling information, and the scheduling information indicates the terminal equipment to send a first channel;

the terminal equipment acquires configuration information, wherein the configuration information is used for indicating whether the preemption information is effective to the type of the first channel;

the terminal equipment acquires preemption information, wherein the preemption information comprises an instruction for adjusting the power of at least one part of resources in the first channel.

The type of the first channel is any one of the following: the physical random access channel PRACH, a PUSCH scheduled by a physical downlink control channel and not carrying UCI, a PUSCH scheduled by a physical downlink control channel and carrying UCI, a PUCCH scheduled by a physical downlink control channel and carrying UCI, an SRS scheduled by a physical downlink control channel, a PUSCH semi-persistently scheduled and not carrying UCI, a PUSCH semi-persistently scheduled and carrying UCI, a PUCCH semi-persistently scheduled and carrying UCI, an SRS semi-persistently scheduled, a PUSCH configured to transmit and not carrying UCI, a PUSCH configured to transmit and carrying UCI, a PUCCH configured to transmit and to carry UCI, a PUCCH configured to transmit, and an SRS configured to transmit.

For example, the type of the first channel is PUSCH, and the UCI includes at least one of HARQ-ACK and CSI;

for example, the type of the first channel is PUCCH, and the UCI includes at least one of HARQ-ACK, CSI, SR;

preferably, the configuration information is indicated independently for different first channels. The different first channel here refers to at least one of:

different channel classes (e.g., PUSCH and PUCCH);

different scheduling modes (for example, scheduled through a physical downlink control channel, semi-persistent scheduling, or configuration transmission);

the carried UCI types are different, and the UCI types comprise HARQ-ACK, CSI and SR.

And the terminal equipment acquires the preemption indication and adjusts or maintains the sending power of at least one part of resources according to the scheduling information, the configuration information and the preemption information.

As an embodiment of the further optimization of the channel transmission device of the present application, the device further comprises a determining module 3. The determining module is configured to compare the first channel and the second channel, and determine whether the resources overlap. When the resources of the first channel and the second channel are overlapped, the transmission power of at least one part of the resources of the first channel is adjusted (including increasing, stopping or reducing).

In this embodiment, the working process of the channel transmission apparatus for the terminal device is as in the embodiment of the first aspect of this document, which is not described herein again.

Further, the present application also provides a network device, which is an embodiment of the fourth aspect of the present application, and uses the method in the embodiment of the second aspect of the present application, where the network device includes a sending module, configured to send the configuration information and the preemption information, and further configured to send at least one of the first scheduling information and the second scheduling information; the network device also comprises an uplink receiving module used for receiving the first channel and/or the second channel.

When the uplink receiving module receives the first channel, it needs to be described that the network device expects the terminal device on which resources and with what power to send the first channel. Because the network device sends the configuration information and the preemption information to the terminal device, the response of the terminal device is predicted according to the protocol, and the signal is received according to the behavior corresponding to the terminal. Therefore, the uplink receiving module is configured to receive the first channel according to the first scheduling information, the configuration information, and the preemption information.

And if the resources of the first channel and the resources of the second channel are overlapped, and the configuration information indicates that the preemption information is valid for the type of the first channel, determining that the first terminal equipment adjusts the transmission power of at least part of the resources in the first channel. And the uplink receiving module receives the uplink data according to a mode that the first terminal equipment adjusts the sending power of at least one part of resources in the first channel.

And if the resources of the first channel and the resources of the second channel are overlapped, but the configuration information indicates that the preemption information is invalid for the type of the first channel, determining that the first terminal equipment maintains the transmission power of the first channel. The uplink receiving module receives the uplink data according to a mode that the first terminal equipment maintains the transmission power of at least one part of resources in the first channel.

The configuration information, the first scheduling information, the second scheduling information, the first channel, and the second channel are described in various embodiments of the present application and are not described herein again.

The working process of the network device in this embodiment is as described in the second aspect of this application, and is not described herein again.

It should be further noted that the configuration information in the embodiment of the present application refers to configuration information sent by a network device to a first terminal device; the first scheduling information in the embodiment of the present application refers to scheduling information sent by a network device to a first terminal device. That is to say, if the terminal device is a first terminal device in the embodiment of the first aspect of the present application, the scheduling information received by the terminal device is the first scheduling information. That is, when the terminal device is a first terminal device, the scheduling information and the first scheduling information are the same meaning. When the terminal device is a second terminal device, the second scheduling information is a term dedicated to the second terminal device, that is, the second scheduling information is different from the scheduling information described in the embodiment of the first aspect of the present application.
