Description

The field of technology to which the invention belongs

The present invention relates to the field of wireless communication technologies and, in particular, to an apparatus and method for transmitting uplink control information.

State of the art

The uplink control information (UCI) in the Long Term Evolution (LTE) standard includes a hybrid automatic repeat request-acknowledgement (HARQ-ACK), a scheduling request ( scheduling request (SR) and channel state information (CSI), channel quality indication (CQI), precoding matrix indication (PMI), and rank indication (RI)). The HARQ-ACK is used to feed back the reception status information of the downlink data channel, that is, the physical downlink shared channel (PDSCH). When performing a correct reception, the user equipment (user equipment, UE) transmits an ACK. When performing an incorrect reception, the UE transmits a negative acknowledgment (negative acknowledgment, NACK). The base station determines the next scheduling policy, such as retransmission or new transmission, based on the UE feedback information for the PDSCH. SR is scheduling request information sent by the UE to the base station and indicates that the UE should send uplink data. CSI is channel state information fed back by the UE to the base station after the UE measures the channel state, and the information further includes CQI/PMI/RI. CQI is channel quality indicator information, and is used to directly convey channel quality information. The base station may further determine, based on the CQI, a modulation and coding scheme (MCS) for data transmission. When the value of the returned CQI is large, a relatively high modulation and coding scheme and a relatively high code rate can be used, so that more information is transmitted on a limited resource, thereby increasing the data rate. When the value of the returned CQI is relatively small, a relatively low modulation and coding scheme and a relatively low code rate can be used, so that more time-frequency resources are used for data transmission, thereby improving data transmission reliability. Further, the UE measures the CQIs of various frequency domain resources so that the base station can schedule data on a frequency domain resource with good channel quality to obtain frequency domain scheduling gain. PMI is a precoding matrix identifier that is for data transmission and is fed back by the UE to the base station based on the measured channel quality. The base station may determine the appropriate precoding matrix based on the PMI information sent back. RI is rank indicator information and is used to return to the base station information on the number of layers into which the channel can be divided. More levels indicate more data that can be transmitted at the same time. Additionally, some other information is used, such as a channel state information (CRI) reference signal resource indicator used to feed back to the base station the measurement resource whose measured channel quality is the best in the set of measured measurement resources.

The control information may be transmitted using two channels: a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH). In Release 8 (Release) of LTE, a UE is not supported when performing simultaneous transmission of control information using PUCCH and transmission of data information using PUSCH. When UCI and data are transmitted at the same time, multiplexing must be performed for UCI and data. This helps to maintain single carrier uplink performance, thus improving uplink coverage for a user located at the edge of the coverage area. LTE Release 10 introduced a high-level option for simultaneous (simultaneous) use of PUCCH-PUSCH, which supports simultaneous transmission of UCI and data. When transmitting data and UCI at the same time, one part of the UCI is supported for transmission on the PUCCH and another part of the UCI is supported for transmission on the PUSCH. In the absence of a simulcast configuration, if the UCI and data are transmitted simultaneously, the UCI must be transmitted on the PUSCH by multiplexing.

In particular, when the UCI is transmitted on the PUSCH by multiplexing, other information is processed in different ways. The processing method in LTE is as follows: first, in terms of data transmission, the UE generates a transport block (TB) in the medium access control (MAC) layer, and adds bits of cyclic redundancy check (cyclic redundancy check, CRC) into a transport block. The TBs are then segmented into code blocks and CRC bits are added to each code block. Then, each code block to which CRC bits are added is supplied to an encoder for encoding. After encoding, an encoded data rate matching operation must be performed based on the amount of actual time-frequency resources. After rate matching, the code blocks are cascaded to form a data bitstream string. Second, from the point of view of transmitting the UCI, after encoding the CQI, multiplexing must be performed for the encoded CQI and data. After ACK and RI encoding, the encoded ACK and encoded RI are fed into the interleaver along with the CQI/data. The ACK is applied to the interleaver using a data puncture operation, and the ACK is in place next to the PUSCH pilot. The RI is in place next to the ACK, and the rate matching method for the RI is applied. This placement allows the ACK to have relatively good channel estimation performance and the RI has the specific effect of correctly receiving the CQI/PMI. In a process in which the UCI is transmitted on the PUSCH for transmission, the specific time-frequency resource originally scheduled for the PUSCH is separated to transmit control information. Currently, in LTE, a resource for UCI transmission is determined based on the number of UCI information bits and the number of data information bits. However, in NR, the number of UCI information bits increases significantly. Thus, a key technical challenge is to determine how to allocate resources to determine the balance between UCI and data transmission performance.

Disclosure of the essence of the invention

The present invention provides an apparatus and method for transmitting uplink control information for allocating sufficient resources for data and UCI during initial data transmission, thereby improving system performance.

According to a first aspect, the present invention provides a method for transmitting uplink control information, the method including:

determining, by the terminal, based on the first information, the number of resources to transmit the UCI, wherein the first information includes any of the following information combinations: combinations of scheduling information, the ratio of the number of UCI bits to the sum of the number of UCI bits and the number of data bits, the first given parameter, parameter β and the number of available PUSCH resources; a combination of the scheduling information, the first predetermined parameter, the parameter β, the amount of available PUSCH resources, and the code rate of the scheduled data; or a combination of scheduling information, the ratio of the number of UCI bits to the number of data bits, the first given parameter, the parameter β, the number of available PUSCH resources, and the parameter α; and transmitting the UCI by the terminal to the network device based on the determined amount of resources for transmitting the UCI.

The terminal device transmits the UCI to the network device based on the determined amount of resources to transmit the UCI. Since the terminal uses the ratio of the number of UCI bits to the number of data bits as the main ratio for resource division when determining the amount of resources to transmit the UCI, it can be avoided that all resources are allocated by the UCI during the initial transmission and data cannot be transmitted.

In an exemplary implementation, the first given parameter is the product of the first given value and the number of frequency domain REs scheduled for PUSCH and/or the product of the second given value and the number of PUSCH symbols.

In a possible implementation, the first given value is the bandwidth and/or the number of symbols.

The terminal transmits the UCI to the network device based on the amount of resources to transmit the UCI, which is determined according to the above formula.

Implementation of the invention

Fig. 1 is a system architecture diagram to which the present invention is applicable. As shown in FIG. 1, the system architecture includes a network device 101 and one or more terminal devices 102. The network device 101 may transmit downlink data to the terminal device 102 via the network, and the terminal device 102 may transmit uplink data to the network device 101 via the network.

In the present invention, the network device may be a base station (BS) device. A base station device may also be referred to as a base station, and is a device that is deployed in a radio access network to provide a wireless communication function. For example, a device that provides a base station function in a 2G network includes a base transceiver station (BTS) and a base station controller (BSC); a device that provides the function of a base station in a 3G network includes a node B (NodeB) and a radio network controller (radio network controller, RNC); a device that provides the function of a base station in a 4G network includes an advanced Node B (evolved NodeB, eNB); and a device that provides the function of a base station in a 5G network includes a New Radio NodeB (New Radio NodeB, gNB), a centralized unit (Centralized Unit, CU), a distributed unit (Distributed Unit) and a new radio network controller.

A terminal device is a device that has a wireless transmission/reception function. The terminal may be deployed on land and includes an indoor device, an outdoor device, a portable device, or a device installed in a vehicle; or can be deployed on the water (for example, on a ship); or may be deployed in the air (eg by aircraft, balloon or satellite). The terminal device can be a mobile phone (mobile phone), a tablet (Pad), a computer with a wireless transmission/reception function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal device in industrial control systems, wireless terminal in self-driving system, wireless terminal in remote medical system, wireless terminal in smart grid, wireless terminal in a transport safety system, a wireless terminal in a smart city system, a wireless terminal in a smart home system, or the like.

In the present invention, the system architecture shown in FIG. 1 is mainly used as an example for description, but the present invention is not limited to them. For example, the present invention can be further applied to a system architecture in which a macro base station communicates with a micro base station. This is not specifically limited.

The communication system in which the mentioned system architecture is applied includes, but is not limited to: time division duplexing-long-term evolution (TDD LTE), frequency division duplexing in standard "Long-term development" (frequency division duplexing-long term evolution, FDD LTE), advanced standard "Long-term development" (long term evolution-advanced, LTE-A) and various promising advanced wireless communication systems (for example, the system of access technology "New radio” (new radio access technology, NR).

Currently in LTE, the channel quality indication (CQI)/precoding matrix indication (PMI) in the uplink control information (UCI) has a limited number of bits, and each carrier has a maximum 64 bits. Given that CQIs/PMIs of a maximum of 16 cells must be sent back, the maximum number of bits is 64 × 16 = 1024. This is less than the number of data bits and therefore has little impact on performance in UCI and data transmission.

However, in NR, the number of UCI information bits becomes large. For example, the amount of information of the channel state information part 2 (CSI part 2) of one cell reaches up to thousands of bits. In this case, the number of UCI information bits may very likely exceed the number of data information bits. All resource elements (resource element, RE) in the PUSCH, with the exception of the resource elements used to transmit the CSI part 1 must be used to transmit the CSI part 2 and, therefore, no data can be transmitted. Therefore, the data cannot actually be sent at the base station side.

To solve this technical problem, in Fig. 2 shows an example of an uplink control information transmission procedure according to the present invention. The procedure may be performed by the terminal device.

As shown in FIG. 2, specifically, the procedure includes the following steps.

Step 201: The terminal device determines, based on the first information, the amount of resources to transmit the UCI.

Step 202: The tag transmits the UCI to the network device based on the determined amount of resources to transmit the UCI.

In the present invention, the UCI includes, but is not limited to: acknowledgment - hybrid automatic repeat request-acknowledgement (HARQ-ACK), scheduling request (SR), CSI part 1, CSI part 2 etc. The CSI information may further include information such as CQI, PMI, and rank indicator (rank indication, RI). Up to step 201, the network device transmits the first indication information to the terminal device. The first indication information includes scheduling information, a parameter β, and a parameter α. The terminal may determine the first information based on the first indication information. The first information may include any one of the following combinations of information: a combination of scheduling information, the ratio of the number of UCI bits to the sum of the number of UCI bits and the number of data bits, the first given parameter, the parameter β, and the number of available PUSCH resources; a combination of the scheduling information, the first predetermined parameter, the parameter β, the amount of available PUSCH resources, and the code rate of the scheduled data; a combination of scheduling information, the ratio of the number of UCI bits to the number of data bits, the first parameter, the given parameter β, the number of available PUSCH resources, and the parameter α; or the like. These information combinations are merely examples and the present invention does not set any limits. In the present invention, the number of resources may be the number of REs. This is just an example and no restrictions are placed on it. It should be noted that the number of UCI bits, the number of data bits, and the amount of available PUSCH resources are negotiated by both the network device and the terminal device, and can be determined by the terminal device without transmission by the network device.

The first predetermined parameter may be the product of the first predetermined value and the number of frequency domain REs scheduled for the PUSCH and/or the product of the second predetermined value and the number of PUSCH symbols. In other words, the first given parameter may be the product of the first given value and the number of frequency domain REs scheduled for the PUSCH, or the first given parameter may be the product of the second given value and the number of PUSCH symbols, or the first given value may be one product of the first given value. and the number of frequency domain resource elements REs scheduled for the PUSCH and the product of the second predetermined value and the number of PUSCH symbols. Perhaps the first given value may be the bandwidth and/or the number of symbols. In other words, the first set value may be a bandwidth, or the first set value may be a number of symbols, or the first set value may be one of a bandwidth and a number of symbols.

In the present invention, LTE is different from NR, when the UCI information is HARQ-ACK information, the HARQ-ACK information is transmitted using a puncturing method when it may be less than 2 bits, and transmitted using rate matching when greater than 2 bit; or when the UCI information is CSI information, the CSI information is further divided into CSI Part 1 and CSI Part 2. The CSI Part 1 priority is higher and the CSI Part 2 priority is lower. The Part 2 CSI value can be determined based on the Part 1 CSI value. The number of Part 2 CSI bits is much larger than in LTE. Both CSI Part 1 and CSI Part 2 are transmitted using rate matching. In order to maintain proper allocation for UCI and data during initial transmission in NR, resources may be appropriately allocated based on the actual ratio of the number of UCI bits to the number of data bits.

When the first information is a combination of scheduling information, the ratio of the number of UCI bits to the sum of the number of UCI bits and the number of data bits, the first given parameter, the parameter β, and the number of available resources of the physical uplink shared channel PUSCH, in a possible implementation, the number of resources for transmitting the UCI is determined in accordance with formula (1).

Следует отметить, что опорная кодовая скорость может представлять собой отношение количества доступных ресурсов данных во время начальной передачи к сумме количества бит UCI и количества бит данных. Это является просто примером в настоящем изобретении, и конкретные ограничения не установлены.

is the number of resources to transmit UCI, O is the number of UCI bits, B is the number of data bits, A is the number of available data resources at the time of initial transmission, C is the maximum number of resources to transmit UCI in the number of scheduled available data resources during transfers, and

the offset of the UCI with respect to the reference code rate. It should be noted that the reference code rate may be the ratio of the number of available data resources at the time of initial transmission to the sum of the number of UCI bits and the number of data bits. This is merely an example in the present invention, and no specific limitations have been set.

Alternatively, O may be the number of bits that are received after adding the CRC check bit to the UCI. In this case, B is the number of bits that are obtained after adding the CRC bit to the data. In this case, B may be the number of bits that are obtained after segmenting a transport block (TB) into code blocks and then adding cyclic redundancy check (CRC) bits to each codebook. This step is typically performed before each codebook is delivered to the encoder. A may represent the number of data REs available during the initial transmission when the UCI is not considered in the NR. Alternatively, A can be represented as the number of available REs that are used for data transmission after using the UCI. Possibly, O may represent the number of bits remaining after discarding some information according to a particular rule when the number of UCI bits is excessively large.

C may represent the maximum number of REs that can be used to transmit the current UCI in the scheduled available REs of this data during the current transmission. If the current UCI is CSI Part 2 and the data rate for HARQ-ACK is used, a possible implementation is the number of scheduled data REs, excluding some Res in CSI Part 1 and HARQ-ACK. If the current UCI is CSI Part 2 and a puncture operation is used for the HARQ-ACK, a possible implementation is the number of data REs scheduled, excluding some of the REs in CSI Part 1.

According to formula (1), the number of UCI bits is in the denominator, so that the calculation result on the left side can be changed by decreasing the value of the scheduled resource A by properly configuring the value of the parameter β. Thus, the data resources are not all occupied by the UCI during initial transmission. Obviously, when allocating resources, the UCI bit information is actually more important than the data. Therefore, if resource allocation is performed entirely based on the ratio between the number of bits, then the UCI code rate is actually higher. In this case, the code rate can be further adjusted by properly configuring the parameter β.

The ratio of the number of UCI bits to the number of data bits used as the main proportion for resource division, and the ratio is further adjusted using the parameter β; so that the case in which all resources are allocated in the UCI at the time of initial transmission can be avoided and data cannot be transmitted.

In another possible implementation, the number of resources for UCI transmission is determined in accordance with formula (2).

is the given offset. The predetermined offset can be set based on experience.

Alternatively, O may be the number of bits that is obtained after adding the CRC bit check bit to the UCI. In this case, B is the number of bits that are obtained after adding the CRC bit to the data. In this case, B may be the number of bits that are obtained after segmenting the TV into code blocks, and then CRC bits are added to each codebook. This step is typically performed before each codebook is delivered to the encoder. A may represent the number of data REs available during the initial transmission when the UCI is not considered in the NR. Alternatively, it can be represented as the number of available REs that are used for data transmission after using the UCI. Possibly, O may represent the number of bits remaining after discarding some information according to a particular rule when the number of UCI bits is excessively large.

C may represent the maximum number of REs that can be used to transmit the current UCI in the scheduled available REs of this data during the current transmission. If the current UCI is CSI part 2 and data rate negotiation is used for HARQ-ACK, a possible implementation is the number of data REs scheduled, excluding some REs in CSI part 1 and HARQ-ACK. If the current UCI is part of CSI 2 and the puncturing method is used for HARQ-ACK, a possible implementation is the number of scheduled data REs, excluding some of the REs in CSI part 1.

According to formula (2), resource allocation is performed by adjusting the ratio of the number of data bits to the number of UCI bits. The ratio of the number of UCI bits to the number of data bits is used as the basic proportion for resource division, and the ratio is adjusted using the parameter β; so that the case in which all resources are allocated by the UCI at the time of initial transmission and data cannot be transmitted can be prevented.

The present invention further provides for an implementation in which the amount of resources for UCI transmission is determined according to formula (3).

Formula (3) can be:

is the offset of the UCI with respect to the reference code rate.

is the number of resources to transmit UCI, O is the number of UCI bits, B is the number of data bits, A is the number of available data resources at the time of initial transmission, C is the maximum number of resources to transmit UCI in the number of scheduled resources available data during transfer time, and

is the given offset. The predetermined offset can be set based on experience.

Alternatively, O may be the number of bits that is obtained after adding the CRC bit check bit to the UCI. In this case, B is the number of bits that are obtained after adding the CRC bit to the data. In this case, B may be the number of bits that is obtained after segmenting the TV into code blocks, and then CRC bits are added to each codebook. This step is typically performed before each codebook is fed to the encoder. A may represent the number of data REs available during the initial transmission when the UCI is not considered in the NR. Alternatively, A can be represented as the number of available REs that are used for data transmission after the UCI is actually counted. Possibly, O may represent the number of bits remaining after discarding some information according to a particular rule when the number of UCI bits is excessively large.

C may represent the maximum number of REs that can be used to transmit the current UCI in the scheduled available REs of this data during the current transmission. If the current UCI is CSI part 2 and rate negotiation is used for HARQ-ACK, a possible implementation is the number of scheduled data REs, excluding some REs in CSI part 1 and HARQ-ACK. If the current UCI is CSI part 2 and the data puncturing method for HARQ-ACK is applied, a possible implementation is the number of data REs scheduled, excluding some number of REs in CSI part 1.

In accordance with formula (3), resource allocation is carried out by adjusting the weighted ratio of the number of data bits to the number of UCI bits. The ratio of the number of UCI bits to the number of data bits is used as the basic ratio for resource sharing, and the ratio is adjusted with the parameter β; so that the case in which all resources are allocated by the UCI at the time of initial transmission and data cannot be transmitted can be prevented.

When the first information is a combination of the scheduling information, the first given parameter, the parameter β, the amount of available PUSCH resources, and the code rate for data scheduling, in a possible implementation, the terminal determines, according to formula (4), the amount of resources to transmit the UCI.

Formula (4) can be:

(4), где

(4), where

является количество ресурсов для передачи UCI, О представляет собой количество бит UCI, R представляет собой скорость кодирования данных, С представляет собой максимальное количество ресурсов для передачи UCI в количестве запланированных доступных ресурсов данных во время передачи, и

is the number of resources to transmit the UCI, O is the number of UCI bits, R is the data encoding rate, C is the maximum number of resources to transmit the UCI in the number of scheduled available data resources at the time of transmission, and

is the specified offset. The predetermined offset can be set based on experience.

Alternatively, O may be the number of bits that is obtained after adding the CRC bit check bit to the UCI. C may represent the maximum number of REs that can be used to transmit the current UCI in the scheduled available REs of this data during the current transmission. If the current UCI is CSI part 2, and use rate negotiation for HARQ-ACK, a possible implementation is the number of scheduled data REs, excluding some REs in CSI part 1 and HARQ-ACK. If the current UCI is CSI Part 2 and a data puncture method is used for the HARQ-ACK, a possible implementation is the number of data REs scheduled, excluding some REs in CSI Part 1. Perhaps O could represent the number of bits left after some information is discarded according to a specific rule when the number of UCI bits is excessively large.

R in formula (4) is a data code rate, and a data code rate is a code rate corresponding to the MCS. The UE uniquely determines R based on the MCS specified in the data scheduling, and calculates the number of available REs of the corresponding UCI based on R. The code rate is the code rate used for the actual data transmission, and the above technical problem does not exist.

The terminal uses R as a code rate reference according to formula (4), and adjusts the code rate using the parameter β; so that the case in which all resources are allocated in the UCI at the time of initial transmission can be avoided and no data can be transmitted.

When the first information is a combination of scheduling information, the ratio of the number of UCI bits to the number of data bits, the first given parameter, the parameter β, the number of available PUSCH resources, and the parameter α, in a possible implementation, the terminal device determines, according to formula (5), the amount of resources for UCI transfers.

Formula (5):

(5), где

(5), where

является количество ресурсов для передачи UCI, О представляет собой количество бит UCI, В представляет собой количество бит данных, А представляет собой количество доступных ресурсов данных во время начальной передачи, С представляет собой максимальное количество ресурсов для передачи UCI в количестве запланированных доступных ресурсов данных во время передачи,

представляет собой смещение UCI по отношению к опорной кодовой скорости, и

является параметром. В этом случае, опорная кодовая скорость может представлять собой отношение количества доступных ресурсов данных в ходе начальной передачи к количеству бит данных. Это является просто примером в настоящем изобретении, и никаких ограничений не установлено.

is the number of resources to transmit UCI, O is the number of UCI bits, B is the number of data bits, A is the number of available data resources at the time of initial transmission, C is the maximum number of resources to transmit UCI in the number of scheduled available data resources during transmission,

is the offset of the UCI with respect to the reference code rate, and

is a parameter. In this case, the reference code rate may be the ratio of the number of available data resources during initial transmission to the number of data bits. This is merely an example of the present invention and no limitation is stated.

Alternatively, O may be the number of bits that is obtained after adding the CRC check bit to the UCI. In this case, B is the number of bits that are obtained after adding the CRC bit to the data. In this case, B may be the number of bits that is obtained after segmenting the TV into code blocks, and then CRC bits are added to each codebook. This step is typically performed before each codebook is delivered to the encoder. A may represent the number of data REs available during the initial transmission when the UCI is not considered in the NR. Alternatively, it can be represented as the number of available REs that are used for data transfer after the UCI is actually counted. Possibly, O may represent the number of bits remaining after some information is discarded according to a particular rule when the number of UCI bits is excessively large.

C may represent the maximum number of REs that can be used to transmit the current UCI in the scheduled available REs of this data during the current transmission. If the current UCI is the CSI Part 2, and the rate matching method for HARQ-ACK is used, a possible implementation is the number of data REs scheduled, excluding some REs in CSI Part 1 and HARQ-ACK. If the current UCI is CSI part 2 and the puncture method for HARQ-ACK is used, a possible implementation is the number of data REs scheduled, excluding some of the REs in CSI part 1.

The parameter α is added to the element on the right side of formula (5) to limit the value of the UCI in order to prevent the UCI from occupying all available REs. Perhaps the parameter α is typically less than 1. The parameter α may be configured using signaling, eg configured with higher layer signaling, which may be RRC signaling; or may be transmitted using MAC-CE.

The terminal uses the parameter α to limit the REs occupied by the UCI, so that the case in which all resources are allocated in the UCI during the initial transmission and data cannot be transmitted can be prevented.

It should be noted that the C value in the above formulas (1) to (5) strongly correlate with the UCI display method, in other words, the C value is associated with the UCI display method. Based on the fact that both ACK and CSI can be allocated to REs of different RBs in the frequency domain, a possible UCI mapping method can be as follows.

Method 1: There is a limitation in the time domain, and there is an increase in the frequency domain.

The number of symbols to which the UCI is mapped on the time domain resource is less than or equal to the third predetermined value, and the number of symbols to which the UCI is mapped to the frequency domain resource is of the UCI type. The third value is one or more of the following values: a specified number of symbols near the demodulation reference signal (DMRS), a value related to the number of PUSCH symbols, a value related to a frequency hopping PUSCH, a value related to an additional DMRS and the like.

For example, as shown in FIG. 3, the third predetermined value may be a predetermined number of symbols near the DMRS, and may be a fixed value that is set based on experience, for example, may indicate fixed N symbols near the DMRS, where N is greater than or equal to 1. As shown at position A in fig. 3, N is 2, and the third set value is 2. In this case, the value of C is the product of the symbol number 2 and the bandwidth.

The third predetermined value is a value relating to the number of PUSCH symbols and is associated with the PUSCH time domain length indication, and specifically determined based on the PUSCH time domain indication table. As shown at position B in FIG. 3, when PUSCH is 7 symbols, the third set value may indicate one symbol; and when PUSCH is 14 symbols, the third value may indicate two symbols. For example, when PUSCH is 7 symbols, the value of C may be the product of the number of 1 symbols and the bandwidth.

The third set value may be a value related to PUSCH with frequency hopping. As shown at position C in FIG. 3, when frequency hopping is supported, a symbol is symmetrically distributed on the frequency hopping resource. For example, when the PUSCH does not support frequency hopping, then the value indicates symbol 1 or 2. When the PUSCH frequency supports frequency hopping, then the value indicates symbol 1 and symbol 8. For example, when PUSCH does not support frequency hopping, the value C may be the product of number of 1 symbol and bandwidth.

Alternatively, the third set value may be a value related to supporting additional DMRS. When there is one DMRS, the number of symbols is 1 and when there are two DMRSs, the number of symbols is 2. For example, if there is one DMRS, the value of C may be the product of the number of symbols 1 and the bandwidth.

It should be noted that in these several cases, the value of C in the above formulas (1) - (5) is the product of the number of symbols and the bandwidth scheduled for PUSCH.

The UCI may be discretely mapped in the frequency domain, and the discrete allocation block may be a resource block (RB), a resource block group (RBG), a precoding resource block group (PRG), or a subband ( subband).

A possible way to display the UCI in the frequency domain is that the UCI is first mapped to a large granularity, and then mapped to a small granularity. As shown in FIG. 4A in FIG. 4B, FIG. 5A and FIG. 5B, the UCI is displayed in numerical sequence, and is first displayed within the RBG range, that is, the UCI is mapped in the following sequence: to the first RE in RB 0 of RBG 0, the first RE in RB 0 of RBG 1, the first RE in RB 1 of RBG 0 and the first RE in RB1 from RBG 1.

It should be noted that in the present invention, the location where the UCI resides, which is represented by the graph, is the location of the available UCI resource, and the location marked with the number is the location of the resource occupied by the UCI information. All numbers in the present invention are merely examples and no limitation is stated. A similar description is given for subsequent types.

It should be noted that RB and RBG are only examples of different granularity in the frequency domain. Any mapping that satisfies the condition that the UCI is first displayed with more granularity and then displayed with less granularity should be within the protection scope of the present invention. Mapping to the first RE in the RB is only one way, and the UCI may alternatively be mapped to any RE in the RB in due course.

A and B in Fig. 4A and FIG. 4B shows an example in which the UCI is first mapped to one symbol and the "first frequency domain" mapping method is used. B in FIG. 4A and FIG. 4B shows that the locations occupied by the UCIs are relatively staggered from each other. A and B in Fig. 5A and FIG. 5B shows the "first time domain" method and B in FIG. 5A and 5B show that the locations occupied by the UCIs are relatively staggered from each other. In the case of multiple symbols, it may be further considered to perform a specific offset between two symbols to reduce the impact on data or CSI when puncturing for an ACK is performed.

Method 2: There is a clipping in the frequency domain and an increase in the time domain occurs.

The number of symbols to which the UCI is mapped on the frequency domain resource is less than or equal to the fourth predetermined value, and the number of symbols to which the UCI is mapped to the time domain resource is of the UCI type. The fourth set value is one or more of the following values: a set number of REs, a value related to the number of PUSCH symbols, a value related to the PUSCH bandwidth, a value related to the PUSCH phase tracking reference signal (PTRS), and the like.

The fourth predetermined value may be a predetermined number of REs. As shown at position A in Fig. 6, the predetermined number of REs may be a fixed value that is set based on experience, and the value indicates multiple REs, for example, may be 2, 3, or 4. In this case, the value of C is the product of the number of REs and the number of symbols in the time domain.

The fourth set value may be a value related to the number of PUSCH symbols. As shown at position B in FIG. 6, when the number of characters is relatively small, the value is relatively large. For example, when PUSCH is 14 symbols, the value indicates two REs; when PUSCH is 7 characters, the value indicates four REs. The location of the RE in the frequency domain in the PUSCH may be predetermined, eg, may be an RE at the edge of the passband, or may be REs in some RBs of some RBGs, where the RBG is the related passband. For example, when the PUSCH is 14 symbols, the value indicates two REs, and the value of C is the product of the number of 2 REs and the number of symbols in the time domain.

The fourth set value may be a value related to the PUSCH bandwidth. As shown at position C in FIG. 6, when the bandwidth is relatively large, the value is relatively large. When PUSCH is one RB, the value points to one RE. When PUSCH is two RBs, the value indicates two REs. In particular, the fourth setpoint may alternatively be associated with a discrete frequency domain granularity, such as RB, RBG, PRG, or subband. For example, when PUSCH is one RB, the value points to one RE, and the value of C is the product of the number of 1 REs and the number of symbols in the time domain.

The fourth set value may be a value related to PTRS PUSCH. When there is a PTRS, a location near the PTRS can be selected as the RE location in order to achieve relatively good offset frequency equalization and channel estimation. When there are multiple PTRSs, the REs are the same number as the selected PTRSs, and details can be shown in FIG. 7. The location occupied by PTRS is not available for the UCI resource.

It should be noted that in these cases, the value of C in the above formulas (1) to (5) is the product of the number of REs in the frequency domain and the number of symbols in the time domain.

Alternatively, the UCI may also be discretely mapped in the time domain and the discrete allocation unit may be a minislot or slot aggregation.

For a specific RE display sequence, two kinds of considerations in A and B in FIG. 8A and FIG. 8B: "frequency domain first" and "time domain first". "Frequency domain first" corresponds to B in FIG. 8B and "time domain first" corresponds to FIG. 8A.

It should be noted that the UCI in the present invention may be any type of UCI, and may be HARQ-ACK, CSI Part 1 or CSI Part 2. The UCI may be CSI Part 1 or ACK.

The ACK and CSI part 1 mapping methods may be sequential. When both ACK and CSI part 1 exist, the available resource can be further evenly distributed. For example, for RBG in method 1, CSI part 1 is mapped to a resource whose RBG number is an odd number, and an ACK is mapped to a resource whose RBG number is an even number. In the odd resource and the even resource, resource allocation is further performed based on the description of method 1.

As another example, in method 2, the number of REs in the frequency domain is also evenly distributed, an odd-numbered RE used for Part 1 CSI is available, and an even-numbered RE used for ACK is available. Using the ACK and CSI mapping methods of part 1, the protocol can be simplified.

In addition, in order to transmit the CSI Part 2, the multiplexing of the CSI Part 2 and data must be performed. Since the frequency domain first mapping method for data is used, the CSI part 2 must be displayed after performing multiplexing for the CSI part 2 and data.

In a simple form, if the HARQ-ACK is displayed by the puncturing method, after the mapping for the CSI part 1 is completed, the CSI part 2 is placed in front of the data, and then the CSI part 2 is displayed in the frequency domain first method along with the data. Part 1 must be skipped during the CSI mapping process.

If the HARQ-ACK is displayed using the rate matching operation, after both the HARQ-ACK and the CSI part 1, CSI part 2 and data are displayed, as shown at A in FIG. 9A. During mapping, locations occupied by HARQ-ACK and CSI Part 1 shall be skipped for CSI Part 2.

B in FIG. 9B shows that after CSI part 1 and ACK are displayed, CSI part 2 is displayed and symbols occupied by CSI part 1 and ACK are skipped during display for CSI part 2; and then, the data is displayed. During mapping, the characters occupied by CSI part 1 and ACK shall be skipped for CSI part 2.

C in FIG. 9C shows that the two-part display method is used in the case of frequency hopping. The mapping is done in "time domain first" on the two parts of the resources.

When the mapping method 2 is used, the CSI part 2 mapping method can be shown in FIG. 10A and FIG. 10b.

Perhaps, since the network device can control the UCI to be within the configured resource, the above formulas (1)-(4) can be simplified. In particular, the terminal may determine, in accordance with the following formula (6), formula (7), formula (8), or formula (9), the amount of resources to transmit the UCI.

Formula (6):

The parameters in the above formulas (6) to (9) have already been explained in the previous embodiment, and are not described in detail here.

As stated in the foregoing embodiment, the terminal device determines, based on the first information, the number of resources to transmit the UCI, in which the first information includes any one of the following combinations of information: combination of scheduling information, ratio of the number of bits in the UCI to the sum of the number of bits UCI and the number of data bits, the first given parameter, the parameter β and the number of available resources in PUSCH; a combination of the scheduling information, the first given parameter, the parameter β, the amount of available resources in the PUSCH, and the code rate of the scheduled data; or a combination of scheduling information, the ratio of the number of UCI bits and the number of data bits, the first given parameter, the parameter β, the number of available resources in the PUSCH, and the parameter α; and the tag transmits the UCI to the network device based on the determined amount of resources to transmit the UCI. Since the terminal uses the ratio of the number of UCI bits to the number of data bits as the main ratio for resource division when determining the amount of resources to transmit the UCI, it can be avoided that all resources are allocated by the UCI during the initial transmission and data cannot be transmitted.

Based on the same technical concept, FIG. 11 is a diagram of a device in accordance with the present invention. The device may be a terminal device, and may perform the method performed by the terminal device according to any of the preceding embodiments.
