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 (New Radio, NR) system of 5G. Similar to the assisted access (LAA) technology in the 4G Long Term Evolution (LTE) system, the 5G NR network also relates to a technology how to effectively utilize radio resources in an Unlicensed frequency band, which is called NR Unlicensed (NR-U) technology, that is, it is desirable to use the 5G NR technology in the Unlicensed frequency band (Unlicensed band).

In the NR-U, both a Physical Uplink Control Channel (PUCCH) and a Configured and authorized Physical Uplink Shared Channel (CG-PUSCH) may operate in an unlicensed frequency band, and when both the PUCCH and the CG-PUSCH operate in the unlicensed frequency band, if the CG-PUSCH overlaps with the PUCCH in a time domain, according to the principle of NR 15, the terminal multiplexes Uplink Control Information (UCI) on the PUCCH to transmit the CG-PUSCH, and at this time, the CG-PUSCH transmits not only the Configured and authorized Uplink Control Information (CG-UCI) but also UCI including HARQ-ACK and/or CSI.

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

Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

Embodiments of the present invention are described below with reference to the accompanying drawings. The UCI transmission method, the terminal and the network equipment provided by the embodiment of the invention can be applied to a wireless communication system. The wireless communication system may be a 5G system, an Evolved Long Term Evolution (lte) system, or a subsequent lte communication system.

Referring to fig. 1, fig. 1 is a structural diagram of a network system to which an embodiment of the present invention is applicable, and as shown in fig. 1, the network system includes a terminal 11 and a network device 12, where the terminal 11 may be a user terminal or other terminal-side devices, for example: it should be noted that, in the embodiment of the present invention, a specific type of the terminal 11 is not limited, and the terminal may be a terminal-side Device such as a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device). The network device 12 may be a 5G base station, a later-version base station, or a base station in another communication system, or referred to as a node B, an evolved node B, or a Transmission Reception Point (TRP), an Access Point (AP), or another vocabulary in the field, and the network device is not limited to a specific technical vocabulary as long as the same technical effect is achieved. In addition, the network device 12 may be a Master Node (MN) or a Secondary Node (SN). It should be noted that, in the embodiment of the present invention, only the 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 according to an embodiment of the present invention, where the method is applied to a terminal, and as shown in fig. 2, the method includes the following steps:

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

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

In this embodiment of the present invention, the preset condition may be a condition for transmitting the second UCI on the CG-PUSCH resource, and specifically may be indicated by a network device, may also be agreed by a protocol, and may also be autonomously selected by a terminal, which is not further 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: a channel state information CSI first PART (CSI-PART1), a CSI second PART (CSI-PART2) and a hybrid automatic repeat request acknowledgement HARQ-ACK.

For second UCI of different types, conditions for triggering reporting of the UCI are also different, optionally, the second UCI may be configured semi-statically by the network device, for example, when the type of the second UCI is a Channel State Information (CSI) first part or a CSI second part, the terminal may periodically report the CSI 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 (HARQ-ACK), the network device triggers the terminal to generate the second UCI, and transmits the second UCI at the corresponding transmission time.

When the terminal determines that the second UCI is transmitted on the CG-PUSCH resources, 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 UCI number of the independent codes of the first target UCI and M is compared, when the UCI number of the independent codes of the first target UCI is smaller than or equal to M, the UCI transmitted on the CG-PUSCH does not increase beyond the coding capability range of the terminal, and the UCI can not be discarded. When the number of the independently encoded UCI of 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 may appropriately discard a part of the UCI in the first target UCI according to a preset discarding rule, where in this embodiment, the discarded number of the UCI is a value obtained by subtracting M from the number of the independently encoded UCI of the first target UCI.

It should be noted that, because the reliability requirements of different types of UCI (e.g., CG-UCI, HARQ ACK, CSI part1, and CSIPART 2) and data are different, when the CG-UCI, HARQ ACK, and CSI are transmitted on the CG-PUSCH, different types of UCI and data are encoded separately. This causes the coding complexity of the terminal to increase as the UCI type transmitted on the CG-PUSCH increases. However, in the embodiment of the present invention, in a case that the terminal determines that the second UCI is transmitted on the CG-PUSCH resource and the number of UCI for independent coding of the first target UCI is greater than the maximum value of the number of UCI for independent coding supported by the terminal, part of UCI is discarded according to a preset discarding rule. In this way, the type of the UCI transmitted on the CG-PUSCH can be prevented from exceeding the coding capability range of the terminal, so that the transmission of the CG-UCI and the UCI including the HARQ-ACK and/or the CSI on the CG-PUSCH can be realized.

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

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

the dropping priority of the CSI first part is greater than that of HARQ-ACK;

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

The preset discarding rule comprises the following steps: the dropping priority of the CSI second part is greater than that of the CSI first part, the dropping priority of the CSI first part is greater than that of the HARQ-ACK, and the dropping priority of the HARQ-ACK is greater than that of the first UCI. At this time, the predetermined discard rule may understand that the discard order of the 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, when the second target UCI includes HARQ-ACK, the first UCI includes first indication information, where the first indication information is used to indicate bit number information of the HARQ-ACK.

Optionally, in a case that the second target UCI includes a CSI first part, the first UCI includes second indication information, and the second indication information is used to indicate bit number information of the CSI first part.

Optionally, in a case that the second target UCI includes a CSI second part, the first UCI includes third indication information, where the third indication information is used to indicate bit number information of the CSI second part.

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 the UCI may be indicated by, but not limited to, a bit bitmap. 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 UCI carried 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 bit number of HARQ-ACK transmitted through the CG-PUSCH; if the first UCI carries the second indication information, the network device may know the bit number of the CSI first part transmitted by the CG-PUSCH; if the first UCI carries the third indication information, the network device may know the bit number of the CSI second part transmitted by the CG-PUSCH; if the fourth indication information is carried in the first UCI, the network device may know what types of UCI are transmitted by the CG-PUSCH.

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

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

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

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

wherein the number of resources required for transmitting the third target UCI is less 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, the UCI may be continuously discarded according to the preset discarding rule. For example, Resource Element (RE) of the CG-PUSCH Resource actually used for transmitting UCI is X, the number of REs of the second target UCI to be transmitted is Y, and X < Y, at this time, UCI may be discarded according to the preset discarding rule. Specifically, a certain type of UCI in the second target UCI may be selected to discard part or all of the UCI to obtain a third target UCI. It should be understood that after discarding all content of a class of UCI, the number of REs that need to be transmitted is still greater than X, and then the discarding of part or all of the UCI of a certain class of UCI may continue to be selected until the number of REs required to satisfy the discarded second target UCI is less than or equal to X.

Further, when the number of resources used for UCI transmission in the CG-PUSCH resources is greater than or equal to the number of resources required for 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 for 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 CG-PUSCH resources meets the transmission of the first target UCI, and in the case that the number of resources used for UCI transmission in 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, so as to obtain a fourth target UCI; then transmitting the fourth target UCI on the CG-PUSCH resources; wherein the number of resources required for transmitting the fourth target UCI is less than or equal to the number of resources used for UCI transmission in the CG-PUSCH resources. It should be understood that, when the UCI is discarded for the first target UCI to obtain the fourth target UCI, all or part of one type of UCI may be discarded, and multiple types of UCI may also be discarded, and the specific discarding manner may refer to the process of discarding the UCI for the second target UCI to obtain the third target UCI, which is not described herein again.

Further, when the number of the separately encoded UCI of the first target UCI is less than or equal to M and the number of the resource for UCI transmission in the CG-PUSCH resource is greater than or equal to the number of the separately encoded UCI of the first target UCI, the first target UCI may not be discarded, and the first target UCI is directly transmitted on the CG-PUSCH resource.

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

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

the CG-PUSCH resources and Physical Uplink Control Channel (PUCCH) resources are at least partially overlapped on a time domain, and the PUCCH resources are resources configured for the network equipment to transmit the second UCI;

or the terminal fails to Listen Before Talk (LBT) on a first resource, where the first resource is a resource of a PUCCH configured by the network device.

In an embodiment, under the condition that the preset condition includes that the CG-PUSCH resource and the physical uplink control channel PUCCH resource are at least partially overlapped in a time domain, the terminal needs to send the first UCI and the second UCI at a corresponding transmission time, and the CG-PUSCH resource and the PUCCH resource are overlapped in time, at this time, the network device knows which types of UCI are transmitted on the current CG-PUSCH, and the terminal may determine whether to discard the UCI according to the coding capability, code the final remaining UCI, and send the UCI according to a certain rule. In other words, in this embodiment, when multiplexing UCI 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 predetermined condition includes that the terminal fails in LBT on the first resource, at this time, if LBT succeeds 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 equipment, and the first resource is positioned before the second resource in the time domain. That is to say, the terminal may automatically retransmit the second UCI on the CG-PUSCH resource, for example, after the terminal fails to perform LBT on the PUCCH resource configured by the network device, the terminal may perform LBT on the subsequent CG-PUSCH resource successfully, and the terminal may perform (piggyback) retransmission on the CG-PUSCH to retransmit the second UCI, at this time, the network device does not know whether the second UCI is transmitted on the current CG-PUSCH.

It should be appreciated that the second target UCI is transmitted on the CG-PUSCH resource, also indicating that LBT was successful on that 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 resource of a PUCCH configured by the network equipment, the second resource is a resource of a CG-PUSCH configured by the network equipment, and the first resource is positioned before the second resource in a time domain.

Further, the preset condition includes that the terminal fails in a first resource LBT, and the first UCI includes fifth indication information on a condition that a second resource LBT succeeds, 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 discard the UCI; when the terminal determines that the second UCI is transmitted on the CG-PUSCH resource, and the number of the independently coded UCIs of 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 discarding rule.

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

The first embodiment is as follows: the terminal multiplexes the second UCI to the CG-PUSCH resource for transmission, for example, the base station triggers the second UCI to transmit at a corresponding transmission time, and when the CG-PUSCH resource and the PUCCH resource overlap in a 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 CG-UCI and a transmission resource where corresponding data is 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-PART 2. For example, when UCI transmitted on CG-PUSCH resources includes CG-UCI, HARQ-ACK, CSI-PART1, and CSI-PART2, if the number of independently coded UCI supported by the terminal is at most 3, the terminal discards CSI-PART2 in the order of discarding CSI-PART2, CSI-PART1, HARQ-ACK, CG-UCI. And then the CSI-PART1, the HARQ-ACK and the CG-UCI are transmitted according to a certain priority and rule.

Example two: after the configured PUCCH resource LBT fails, and the CG-PUSCH resource after the configured PUCCH resource is LBT successfully, 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 carrying the second UCI, and the UCI transmitted by the CG-PUSCH resource at this time includes the CG-UCI, HARQ-ACK, CSI-PART1, and CSI-PART 2. If the number of independently coded UCI supported by the terminal is at most 3, the terminal discards CSI-PART2 according to the discarding order CSI-PART2, CSI-PART1, HARQ-ACK, CG-UCI. And then the CSI-PART1, the HARQ-ACK and the CG-UCI are transmitted according to a certain priority and rule.

Referring to fig. 3, fig. 3 is a flowchart of another UCI transmission method according to an embodiment of the present invention, where the method is applied to a network device, and as shown in fig. 3, the method includes the following steps:

step 301, receiving a second target UCI sent by a terminal on a CG-PUSCH resource configured with authorization;

Optionally, the type of the second UCI includes at least one of: the Channel State Information (CSI) first part, the CSI second part and the hybrid automatic repeat request acknowledgement (HARQ-ACK).

Optionally, the preset discarding rule includes at least one of the following items:

the dropping priority of the CSI first part is greater than that of HARQ-ACK;

Optionally, the second target UCI, which is sent by the receiving terminal on the resource configured with the granted physical uplink shared channel CG-PUSCH, includes:

receiving a third target UCI sent by the terminal on the CG-PUSCH resources under the condition that the resource quantity used for UCI transmission in the CG-PUSCH resources is less than the resource quantity required for transmitting the second target UCI;

and the terminal discards the second target UCI according to the preset discarding rule to obtain the third target UCI, wherein the number of resources required for transmitting the third target UCI is less than or equal to the number of resources used for UCI transmission in the CG-PUSCH resources.

Optionally, the preset condition is a condition for transmitting the second UCI on the CG-PUSCH resource.

Optionally, the preset conditions include:

or the terminal fails in a first resource LBT, where the first resource is a resource of a PUCCH configured by the network device.
