Description

UCI transmission method, terminal and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a UCI transmission method, a terminal, and a network device.

Background

With the development of wireless communication technology, mobile communication networks gradually evolve to a New air interface (NR) system of 5G. Similar to the assisted access (License Assisted Access, LAA) technique in the 4G long term evolution (Long Term Evolution, LTE) system, the technique of how to effectively use radio resources of Unlicensed frequency bands is also referred to as NR Unlicensed (NR-U) technique in the 5G NR network, that is, it is desirable to use the 5G NR technique on Unlicensed frequency bands.

In NR-U, both the physical uplink control channel (Physical Uplink Control Channel, PUCCH) and the physical uplink shared channel (Configured Grant Physical Uplink Shared Channel, CG-PUSCH) configured with grant may operate in an unlicensed band, when both PUCCH and CG-PUSCH operate in an unlicensed band, if CG-PUSCH overlaps with PUCCH in time domain, according to NR 15 principle, the terminal multiplexes uplink control information (Uplink Control Information, UCI) on PUCCH onto CG-PUSCH for transmission, where CG-PUSCH is required to transmit not only the uplink control information (Configured Grant Uplink Control Information, CG-UCI) configured with grant but also UCI including HARQ-ACK and/or CSI.

Due to different requirements of the reliability of different types of UCI and data, when HARQ ACK and CSI are multiplexed on PUSCH at the same time, the different types of UCI and data are encoded separately. As UCI transmitted on CG-PUSCH increases, coding complexity of a terminal may increase. In the prior art, it is not clear how to transmit CG-UCI on CG-PUSCH, UCI including HARQ-ACK and/or CSI.

It should be noted that, in the embodiment of the present invention, only a 5G base station is taken as an example, but the specific type of the network device is not limited.

Referring to fig. 2, fig. 2 is a flowchart of a method for transmitting uplink control information UCI provided in an embodiment of the present invention, where the method is applied to a terminal, as shown in fig. 2, and includes the following steps:

step 201, performing UCI discarding on a first target UCI according to a preset discarding rule to obtain a second target UCI when a preset condition is satisfied and the number of UCI independently encoded by the first target UCI is greater than M;

step 202, transmitting the second target UCI on a physical uplink shared channel CG-PUSCH resource configured with grant;

In the embodiment of the present invention, the preset condition may be a condition for transmitting the second UCI on the CG-PUSCH resource, specifically, may be indicated by a network device, may be agreed by a protocol, or may be selected by a terminal autonomously, which is not limited herein.

Optionally, the type of the first UCI is CG-UCI. The type of the second UCI may be one or more, for example, in this embodiment, the type of the second UCI may include at least one of the following: channel state information CSI first PART (CSI-PART 1), CSI second PART (CSI-PART 2) and hybrid automatic repeat request acknowledgement HARQ-ACK.

For the second UCI of different types, conditions for triggering UCI reporting are different, and optionally, the second UCI may be semi-statically configured by the network device, for example, when the type of the second UCI is a first part of channel state information (Channel State Information, CSI) or a second part of CSI, the terminal may report CSI periodically according to the configuration of the network device. The second UCI may also be triggered by the network device, for example, when the type of the second UCI is a hybrid automatic repeat request acknowledgement (Hybrid Automatic Repeat Request Acknowledgement, HARQ-ACK), the network device triggers the terminal to generate the second UCI and transmit at the corresponding transmission time.

When the terminal determines that the second UCI is transmitted on the CG-PUSCH resource, the first UCI and the second UCI which need to be transmitted at this time are determined as the first target UCI to be transmitted at this time, then the size relation between the number of UCIs which are independently coded of the first target UCI and M is compared, when the number of UCIs which are independently coded of the first target UCI is smaller than or equal to M, the UCI increase transmitted on the CG-PUSCH is not beyond the coding capacity range of the terminal, and the UCI can not be discarded. When the number of UCI independently coded in the first target UCI is greater than M, it indicates that the UCI transmitted on the CG-PUSCH increases beyond the coding capability range of the terminal, and part of UCI in the first target UCI may be appropriately discarded according to a preset discard rule.

It should be noted that, because different types of UCI (such as CG-UCI, HARQ ACK, CSI PART 1, and CSI PART 2) and data have different reliability requirements, when CG-UCI, HARQ ACK, and CSI are transmitted on CG-PUSCH, different types of UCI and data are encoded separately. This causes an increase in coding complexity of the terminal when UCI type transmitted on CG-PUSCH increases. However, in the embodiment of the present invention, when the terminal determines that the second UCI is transmitted on the CG-PUSCH resource and the number of UCI independently encoded by the first target UCI is greater than the maximum value of the number of UCI independently encoded supported by the terminal, part of UCI is discarded according to a preset discard rule. In this way, the UCI transmitted on the CG-PUSCH is prevented from being more than the coding capability range of the terminal, so that the CG-UCI and UCI including HARQ-ACK and/or CSI can be transmitted on the CG-PUSCH.

It should be understood that the foregoing preset discard rule may be specifically configured by a protocol convention or a network device, and specific rule contents thereof may be set according to actual needs, for example, in an alternative embodiment, the foregoing preset discard rule may include at least one of the following:

the discarding priority of the second part of the CSI is greater than that of the first part of the CSI;

The discarding priority of the CSI first part is greater than the discarding priority of the HARQ-ACK;

the drop priority of the HARQ-ACK is greater than the drop priority of the first UCI.

The method comprises the following steps of: the case where the drop priority of the CSI second part is greater than the drop priority of the CSI first part, the drop priority of the CSI first part is greater than the drop priority of the HARQ-ACK, and the drop priority of the HARQ-ACK is greater than the drop priority of the first UCI is described. At this time, the foregoing preset discard rule may understand that the discard order of UCI is: CSI-PART2, CSI-PART1, HARQ-ACK, CG-UCI. For example, the value of M is 3, and the types of UCI in the second UCI include CSI-PART2, CSI-PART1, and HARQ-ACK. At this time, the types of UCI in the second target UCI may include CG-UCI, CSI-PART1, and HARQ-ACK.

Optionally, in case that the second target UCI includes HARQ-ACK, the first UCI includes first indication information for indicating bit number information of the HARQ-ACK.

Optionally, in case that the second target UCI includes a CSI first portion, the first UCI includes second indication information for indicating bit number information of the CSI first portion.

Optionally, in case the second target UCI includes a CSI second portion, the first UCI includes third indication information for indicating bit number information of the CSI second portion.

Optionally, the first UCI includes fourth indication information, where the fourth indication information is used to indicate type information of UCI carried by the CG-PUSCH.

It should be noted that, the type information of UCI may be indicated by, but not limited to, a bit map. By carrying the first indication information, the second indication information, the third indication information and the fourth indication information in the first UCI, unsuccessful demodulation caused by inconsistent understanding of the type and the number of bits of the carried UCI by the base station and the terminal can be avoided. For example, when the network device receives the first UCI, if the first UCI carries the first indication information, the network device may know the number of bits of HARQ-ACK transmitted by CG-PUSCH; if the first UCI carries the second indication information, the network device may know the number of bits of the CSI first portion of the CG-PUSCH transmission; if the first UCI carries the third indication information, the network device may know the number of bits of the CSI second portion of the CG-PUSCH transmission; if the first UCI carries the fourth indication information, the network device may know what types of UCI are transmitted by the CG-PUSCH.

In this embodiment, when the UCI of the CG-PUSCH bearer includes the first UCI and the second UCI, the fourth indication information may only indicate type information of the second UCI, or may indicate type information of the first UCI and the second UCI.

Further, in order to ensure the reliability of the transmission, in the embodiment of the present invention, it may also be determined whether the number of resources used for UCI transmission in the CG-PUSCH resources satisfies the transmission of the second target UCI, for example, the step 202 includes:

under the condition that the number of resources used for UCI transmission in the CG-PUSCH resources is smaller than the number of resources required for transmitting the second target UCI, UCI discarding is carried out on the second target UCI according to the preset discarding rule, and a third target UCI is obtained;

transmitting the third target UCI on the CG-PUSCH resource;

the number of resources required for transmitting the third target UCI is smaller than or equal to the number of resources used for UCI transmission in the CG-PUSCH resources.

In this embodiment, if the number of resources used for UCI transmission in the CG-PUSCH resources is not enough to transmit the second target UCI, UCI may also be discarded according to the preset discard rule. For example, CG-PUSCH resources are actually used to transmit UCI with Resource Element (RE) being X, the number of REs of the second target UCI to be transmitted being Y, and X < Y, where UCI may be discarded according to the preset discard rule. Specifically, a third target UCI may be obtained after some UCI in the second target UCI is discarded or all UCI in the second target UCI is selected. It should be appreciated that after discarding the entire content of one type of UCI, the number of REs needed to be transmitted is still greater than X, and discarding part or all of UCI selected for a certain type of UCI may be continued until the number of REs needed to satisfy the second target UCI after discarding is less than or equal to X.

Further, in the case that the number of resources used for UCI transmission in the CG-PUSCH resources is greater than or equal to the number of resources required by the second target UCI, the second target UCI is not discarded, and the second target UCI is directly transmitted on the CG-PUSCH resources.

It should be noted that, when the number of UCI independently encoded in the first target UCI is less than or equal to M, it may also be determined whether the number of resources used for UCI transmission in the CG-PUSCH resources satisfies the transmission of the first target UCI, and when the number of resources used for UCI transmission in the CG-PUSCH resources is less than the number of resources required for transmitting the first target UCI, UCI discarding may be performed on the first target UCI according to the preset discarding rule to obtain a fourth target UCI; then transmitting the fourth target UCI on the CG-PUSCH resource; the number of resources required for transmitting the fourth target UCI is smaller than or equal to the number of resources used for UCI transmission in the CG-PUSCH resources. It should be understood that when UCI discarding is performed on the first target UCI to obtain the fourth target UCI, all or part of UCI of one type may be discarded, and multiple types of UCI may be discarded, and a specific discarding manner may refer to a process of performing UCI discarding on the second target UCI to obtain the third target UCI, which is not described herein.

Further, when the number of UCI independently encoded in the first target UCI is less than or equal to M and the number of resources used for UCI transmission in CG-PUSCH resources is greater than or equal to the number of UCI independently encoded in the first target UCI, UCI may be directly transmitted on the CG-PUSCH resources without performing UCI discarding on the first target UCI.

It should be noted that, in an alternative embodiment, the problem of the number of resources may be not considered, and the resources are not discarded regardless of insufficient resources.

The preset conditions may be set according to actual needs, for example, in an alternative embodiment, the preset conditions include:

the CG-PUSCH resource and a Physical Uplink Control Channel (PUCCH) resource are at least partially overlapped in a time domain, and the PUCCH resource is a resource configured by network equipment for transmitting the second UCI;

or, the terminal fails in a first resource listen before talk (Listen Before Talk, LBT), the first resource being a resource of PUCCH configured by the network device.

In an embodiment, when the preset condition includes that the CG-PUSCH resource and the physical uplink control channel PUCCH resource at least partially overlap in the time domain, the terminal needs to send the first UCI and the second UCI at corresponding transmission times, and the CG-PUSCH resource and the PUCCH resource have time overlapping, at this time, the network device knows which types of UCI are transmitted on the current CG-PUSCH, and the terminal can determine whether to discard the UCI according to the coding capability, and code the final remaining UCI and send the UCI according to a certain rule. In other words, in this embodiment, when UCI is multiplexed to CG-PUSCH resources for transmission, the terminal may determine whether to discard UCI according to coding capability, encode the final remaining UCI, and transmit according to a certain rule.

In another embodiment, in the case that the preset condition includes that the terminal fails in the first resource LBT, at this time, if the LBT is successful on a second resource subsequent to the first resource, the second UCI may be transmitted on the second resource. The second resource is a CG-PUSCH resource configured by the network device, and the first resource is located before the second resource in a time domain. That is, the terminal may automatically retransmit the second UCI on the CG-PUSCH resource, for example, after the terminal fails to make LBT on the PUCCH resource configured by the network device, the terminal succeeds in making LBT on the subsequent CG-PUSCH resource, and the terminal may retransmit the second UCI on the CG-PUSCH bearer (piggyback), where the network device does not know whether the second UCI is transmitted on the current CG-PUSCH.

It should be appreciated that transmitting the second target UCI on the CG-PUSCH resource also indicates that LBT was successful on the CG-PUSCH resource. In other words, in this embodiment, the preset condition may include that the terminal fails in the first resource LBT and succeeds in the second resource LBT; the first resource is a PUCCH resource configured by the network equipment, the second resource is a CG-PUSCH resource configured by the network equipment, and the first resource is positioned before the second resource in the time domain.

Further, the preset condition includes that the terminal fails in a first resource LBT, and the first UCI includes fifth indication information when the second resource LBT is successful, where the fifth indication information is used to indicate whether the CG-PUSCH carries the second UCI.

Optionally, in an optional embodiment, the preset condition further includes that the fifth indication information indicates that the CG-PUSCH resource carries the second UCI.

In other words, when the terminal determines that the second UCI is not transmitted on the CG-PUSCH resource, the fifth indication information indicates that the CG-PUSCH resource does not carry the second UCI, and at this time, the terminal does not perform UCI discarding; when the terminal determines that the second UCI is transmitted on the CG-PUSCH resource, and the number of UCI independently encoded by the first target UCI is greater than M, the fifth indication information indicates that the CG-PUSCH resource carries the second UCI, and at this time, the terminal discards the UCI according to the preset discard rule.

For a better understanding of the present invention, specific implementation procedures of the present invention are described in detail below.

Embodiment one: the terminal multiplexes the second UCI to the CG-PUSCH resource for transmission, for example, when the base station triggers the second UCI to be transmitted at the corresponding transmission time and the CG-PUSCH resource and the PUCCH resource overlap in the time domain, the second UCI is carried on the CG-PUSCH resource for transmission. It should be understood that, in this embodiment, the CG-PUSCH resource is a transmission resource where the CG-UCI and corresponding data are located, and the CG-UCI is used for the network device to demodulate the data transmitted by the CG-PUSCH resource.

The UCI transmitted on the CG-PUSCH resource at this time may include at least one of CG-UCI, HARQ-ACK, CSI-PART1, and CSI-PART2. For example, when UCI transmitted on CG-PUSCH resources includes CG-UCI, HARQ-ACK, CSI-PART1, and CSI-PART2, if the number of UCI of independent codes supported by the terminal is at most 3, CSI-PART2, CSI-PART1, HARQ-ACK, CG-UCI, and CSI-PART2 are discarded by the terminal according to the discard order. And then, carrying out coding transmission on the CSI-PART1, the HARQ-ACK and the CG-UCI according to a certain priority and rule.

Embodiment two: after the configured PUCCH resource LBT fails, and the CG-PUSCH resource after the configured PUCCH resource is successfully LBT, the terminal automatically retransmits UCI on the CG-PUSCH resource, and at the moment, the network equipment does not know whether the second UCI is transmitted on the current CG-PUSCH resource. The first UCI indicates whether the CG-PUSCH resource has information for bearing the second UCI, and at the moment, the UCI transmitted by the CG-PUSCH resource comprises CG-UCI, HARQ-ACK, CSI-PART1 and CSI-PART2. If the number of UCIs supported by the terminal is at most 3, the terminal discards the CSI-PART2 according to the discarding sequence of the CSI-PART2, the CSI-PART1, the HARQ-ACK and the CG-UCI. And then, carrying out coding transmission on the CSI-PART1, the HARQ-ACK and the CG-UCI according to a certain priority and rule.

And the third target UCI is obtained by discarding the UCI of the second target UCI by the terminal according to the preset discarding rule, and the number of resources required for transmitting the third target UCI is smaller than or equal to the number of resources used for UCI transmission in the CG-PUSCH resources.

Optionally, the preset condition is a condition that the second UCI is transmitted on the CG-PUSCH resource.
