Description

Communication method and device

Technical Field

The present application relates to the field of communications, and in particular, to a communication method and apparatus.

Background

The 5th generation (5G) mobile communication system supports transmission of Uplink Control Information (UCI) on a Physical Uplink Shared Channel (PUSCH), and there is a scenario in which only UCI is transmitted and no uplink shared channel (UL-SCH) is transmitted, that is, a UCI-only scenario exists.

The UCI sent in the UCI-only scenario may include a hybrid automatic repeat request acknowledgement (HARQ-ACK), a first channel state information part (CSI-part 1), and a second channel state information part (CSI-part2), where the requirements for the protection level are sequentially reduced according to the above order, and therefore, when mapping the above three information onto a resource, the terminal device may map the HARQ-ACK, the CSI-part1, and the CSI-part2 onto a data-loadable Resource Element (RE) of the PUSCH according to the quality of channel estimation.

In order to obtain frequency hopping gain, the PUSCH may be divided into two parts, namely, a first hop (hop1) and a second hop (hop2), in the time domain, and in order to obtain the largest frequency hopping gain, the frequency domain resources of the

hops

1 and 2 are generally far apart and generally do not completely overlap. Accordingly, HARQ-ACK, CSI-part1, and CSI-part2 may also be mapped to hop1 and hop2 according to a preset rule, however, CSI-part1 mapped to a hopping resource may have an incomplete information transmission phenomenon, that is, a part of CSI-part1 is not successfully transmitted, which adversely affects application of UCI transmission through hopping in a UCI-only scenario.

Disclosure of Invention

The application provides a communication method and device, and the problem that information transmission is incomplete in CSI-part1 due to the fact that UCI is transmitted through frequency hopping in a UCI-only scene can be solved by changing the mapping rule of CSI-part 1.

In a first aspect, a communication method is provided, including: receiving downlink control information, wherein the downlink control information is used for scheduling PUSCH (physical uplink shared channel) which is only used for transmitting UCI (uplink control information), and the PUSCH comprises a first frequency hopping resource and a second frequency hopping resourceThe time domain starting symbol of the first frequency hopping resource is positioned before the time domain starting symbol of the second frequency hopping resource; transmitting a first UCI on a PUSCH, the first UCI including at least one of HARQ-ACK, CSI-part1, and CSI-part 2; the number of coding bits mapped on the first frequency hopping resource by the CSI-part1 in the first UCI is G^CSI-part1(1) The number of coding bits mapped on the second frequency hopping resource by the CSI-part1 in the first UCI is G^CSI-part1(2)，G^CSI-part1(1) Greater than or equal to G^CSI-part1(2)。

It should be noted that the PUSCH includes a first frequency hopping resource and a second frequency hopping resource, which means that when the network device instructs the frequency hopping identifier field of the DCI of the uplink grant (UL grant) to enable the PUSCH to perform frequency hopping, the time-frequency domain resources of the PUSCH in the first hop and the time-frequency domain resources of the PUSCH in the second hop are respectively called the first frequency hopping resource and the second frequency hopping resource. In order to distinguish, the first frequency hopping resource and the second frequency hopping resource of the PUSCH in the present application have a precedence relationship in the starting timing sequence. In addition, the value of the number of coded bits mapped on a certain number of REs of the PUSCH is equal to the number of REs multiplied by the number of transmission layers of the PUSCH and further multiplied by the modulation order of the UCI potentially transmitted on the PUSCH.

The reason why the sending of the information is incomplete in the CSI-part1 is that the number of coded bits mapped on the second frequency hopping resource by the CSI-part1 is small, that is, the number of REs used for mapping the CSI-part1 on the second frequency hopping resource is small, so that the CSI-part1 cannot be completely mapped on the second frequency hopping resource, and the communication scheme provided by the application increases the number of coded bits mapped on the first frequency hopping resource by the CSI-part1 and reduces the number of coded bits mapped on the second frequency hopping resource by the CSI-part1, compared with the prior art, thereby solving the problem that the sending of the information is incomplete in the CSI-part1 due to the fact that UCI is transmitted through frequency hopping in the UCI-only scene.

Alternatively, G^CSI-part1(1) The smaller of the first value and the second value, the first value is based on the number G of coded bits of CSI-part1 in the first UCI^CSI-part1Determined, the second value being based on G^ACK(1) And

and mapping the number of coded bits on the reserved RE in the first frequency hopping resource. Wherein, when the number of HARQ-ACK bits is greater than 2, the number of ACK bits is less than the number of ACK bits

Is equal to 0, said number of HARQ-ACK bits being less than or equal to 2(0, 1 or 2)Is equal to the value calculated on the assumption that the number of HARQ-ACK bits is equal to 2.

The above "number of coded bits mapped on the first frequency hopping resource by the HARQ-ACK in the first UCI" refers to the number of coded bits that can be mapped on the first frequency hopping resource by the HARQ-ACK in the first UCI. The above "number of coded bits mapped on the reserved REs in the first frequency hopping resource" refers to the number of coded bits that the reserved REs in the first frequency hopping resource can map, and should not be understood as the number of coded bits that the reserved REs in the first frequency hopping resource actually map.

Optionally, the first value is based on the number of encoding bits G of CSI-part1 in the first UCI^CSI-part1The determination comprises the following steps: the first value is equal to

Optionally, the second value is based on G^ACK(1) And

the larger value of the two is determined, including: second number, etc

Alternatively, the first and second electrodes may be,

the second value is based on G^ACK(1) OrThe determination comprises the following steps: the second value is equal to M when the number of bits of HARQ-ACK is greater than 2₁·N_L·Q_m-G^ACK(1) (ii) a Or, when the number of bits of the HARQ-ACK is less than or equal to 2, the second value is equal to

Wherein M is₁For the number of REs capable of transmitting data in the first frequency hopping resource, N_LNumber of transmission layers, Q, for PUSCH_mIs the modulation order of the first UCI.

The number of bits of the HARQ-ACK is different, the resources used for transmitting the HARQ-ACK on the first frequency hopping resource are also different, and the remaining resources capable of transmitting the CSI-part1 can be determined according to the actual situation of the resources used for transmitting the HARQ-ACK on the first frequency hopping resource, so that the number of coding bits mapped on different frequency hopping resources by the CSI-part1 can be reasonably allocated, and incomplete sending of the CSI-part1 caused by the fact that the resources are not enough to bear the number of coding bits of the CSI-part1 is avoided.

In a second aspect, the present application further provides a communication method, including: sending downlink control information, wherein the downlink control information is used for scheduling a PUSCH (physical uplink shared channel) which is only used for transmitting UCI (uplink control information), the PUSCH comprises a first frequency hopping resource and a second frequency hopping resource, and a time domain starting symbol of the first frequency hopping resource is positioned in front of a time domain starting symbol of the second frequency hopping resource; receiving a first UCI on a PUSCH, the first UCI comprising at least one of HARQ-ACK, CSI-part1, and CSI-part 2; the number of coding bits mapped on the first frequency hopping resource by the CSI-part1 in the first UCI is G^CSI-part1(1) The number of coding bits mapped on the second frequency hopping resource by the CSI-part1 in the first UCI is G^CSI-part1(2)，G^CSI-part1(1) Greater than or equal to G^CSI-part1(2)。

Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

Fig. 1 shows a communication system to which the present application is applicable. The communication system comprises a network device and a terminal device, wherein the network device and the terminal device communicate through a wireless network, when the terminal device sends information, a wireless communication module of the terminal device can acquire information bits to be sent to the network device through a channel, and the information bits are generated by a processing module of the terminal device, received from other devices or stored in a storage module of the terminal device.

In this application, a terminal device may be referred to as an access terminal, User Equipment (UE), subscriber unit, subscriber station, mobile station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or user equipment. An access terminal may be a cellular telephone, a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, and a user device in a 5G communication system.

The network device may be a Base Transceiver Station (BTS) in a Code Division Multiple Access (CDMA) system, a base station (node B, NB) in a Wideband Code Division Multiple Access (WCDMA) system, an evolved node B (eNB) in a Long Term Evolution (LTE) system, or a base station (gNB) in a 5G communication system, where the base station is merely an example, and the network device may also be a relay station, an access point, a vehicle-mounted device, a wearable device, and other types of devices.

The above-described communication system to which the present application is applied is merely an example, and the communication system to which the present application is applied is not limited thereto, and for example, the number of network devices and terminal devices included in the communication system may also be other numbers.

In order to facilitate understanding of the technical solution of the present application, the concepts related to the present application are briefly introduced, and the following is described by taking a 5G system as an example.

In a scenario that the UE sends UCI to the gNB through the PUSCH, since the UE may miss detection of a downlink control channel (PDCCH), an error occurs in the cognition of the HARQ-ACK bit number that needs to be fed back, that is, the HARQ-ACK bit number actually fed back by the UE is less than the HARQ-ACK bit number that the gNB schedules for feedback; and may also result in that all UCI transmitted by the UE via PUSCH cannot be correctly received by the gNB. In order to avoid the CSI-part1 being affected by the UE transmitting less HARQ-ACKs, the communication protocol defines reserved REs (reserved REs for HARQ-ACKs), i.e., reserved REs, for HARQ-ACKs in the scenario that the UE transmits UCI to the gNB through PUSCH. The specific definition is:

(1) when the number of HARQ-ACK information bits is 0,1, or 2, the reserved REs are generated in accordance with the number of HARQ-ACK information bits being 2.

(2) The CSI-part1 with higher protection level requirement cannot be sent on the reserved RE, so that the sending loss of the HARQ-ACK does not affect the CSI-part1 when the number of information bits is not more than 2.

(3) CSI-part2 and UL-SCH may be transmitted on the reserved REs (only the possibility of transmitting CSI-part2 in UCI-only scenarios).

(4) If there are HARQ-ACK information bits to send (i.e. the number of HARQ-ACK information bits is 1 or 2), then HARQ-ACK is sent on the reserved REs. This time, equivalent to HARQ-ACK, puncturing CSI-part2 that has been mapped on the reserved REs.

To obtain frequency hopping gain, PUSCH may be divided into two parts, front and back, in the time domain, which are respectively referred to as a first hop (hop1) and a second hop (hop2), and frequency domain resources of hop1 and hop2 may be the same or different. Accordingly, HARQ-ACK, CSI-part1, and CSI-part2 are also mapped to hop1 and hop2 according to a preset rule.

The mapping rule can be visually represented by fig. 2. As shown in fig. 2, CSI-part1 maps only to unreserved REs; CSI-part2 has both parts mapped to reserved REs and parts mapped to unreserved REs; if there is a HARQ-ACK (i.e. information bits are 1 or 2), then mapping onto reserved REs (equivalent to puncturing over the resources to which the coded bits of CSI-part2 have been mapped).

For the hopping of PUSCH, the following is specified:

the frequency hopping rule of the number of the PUSCH symbols comprises frequency hopping in a slot (slot) and frequency hopping among the slots, and specifically comprises the following steps:

for frequency hopping within slot, the number of hops 1 is half the total number of PUSCH symbols and rounded down, i.e., the number of hops is rounded down

The number of the hop2 symbols is the sum of the PUSCH symbols minus the number of the hop1 symbols, i.e. the number of the hop2 symbols

Wherein

The total number of symbols in one slot for PUSCH.

For inter-slot hopping, hops 1 and 2 are divided in time in slots. For example, a hop1 is even slot and a hop2 is odd slot.

From a demodulation reference signal (DMRS) pattern in the case of PUSCH frequency hopping specified by the current protocol, the cases where frequency hopping may occur in a slot include: the number of data-bearing symbols of hop1 and hop2 is equal; alternatively, hop1 has 1 fewer data-bearing symbols than hop 2; hop1 and hop2 may carry equal numbers of symbols in the case of inter-slot hopping.

The frequency hopping splitting rule for reserving the number of coded bits mapped by the RE is as follows:

assume that the number of coded bits mapped by the reserved RE is

The number of coded bits mapped by reserved REs of hop1 and hop2 is equal to

Wherein N is_LFor PUSCH transmission layer number, Q_mIs the PUSCH modulation order. As can be seen from the formulas (1) and (2),

the equal sign in the formula (3) and the formula (4) is only

Can divide (2. N) completely_L·Q_m) This is true.

In the conventional standard, in a UCI-only scene, the number of coded bits of each part of UCI (HARQ-ACK, CSI-part1, and CSI-part2) is also split according to a certain rule under the condition of frequency hopping. Before the splitting is said, the following three parameters are defined:

number of REs that can carry data on hop 1:wherein

Is the number of the symbols of hop1,

is a set

Size, set of

Is the number of REs that can carry data on the symbol l.

Number of REs that can carry data on hop 2:

whereinThe number of the hop2 symbols.

The number of REs that can carry data on the PUSCH symbol after the first set of consecutive DMRS symbols on PUSCH hop 1:

wherein l⁽¹⁾Is defined as a first DMRS-free symbol index following a first set of consecutive DMRS symbols; the first set of consecutive DMRS symbols may include 1 DMRS symbol, or may include a plurality of consecutive DMRS symbols.

It should be noted in this application that the first set of consecutive DMRS symbols is interpreted to start from the first DMRS symbol in the time domain of the corresponding resource until the consecutive DMRS symbols end. Referring to fig. 3 in particular, fig. 3 shows, from top to bottom (the top and bottom order is only used for logically distinguishing 4 PUSCH resources, and does not define any frequency domain positional relationship), 4 PUSCH resources, PUSCH1, PUSCH2, PUSCH3 and PUSCH4, where the starting symbols of PUSCH1 and PUSCH3 are DMRS symbols, and the starting symbols of PUSCH2 and PUSCH4 are not DMRS symbols. In addition, the first group of consecutive DMRS symbols in PUSCH1 and PUSCH2 only contains 1 symbol, and the first group of consecutive DMRS symbols in PUSCH3 and PUSCH4 contains a plurality of symbols. On PUSCH1, the first set is consecutiveThe DMRS symbol of (1) comprises one DMRS symbol⁽¹⁾Is the index of symbol 1; on PUSCH2, a first set of consecutive DMRS symbols contains one DMRS symbol,/⁽¹⁾Is the index of symbol 2; on PUSCH3, a first set of consecutive DMRS symbols contains two DMRS symbols, l⁽¹⁾Is the index of symbol 2; on PUSCH4, a first set of consecutive DMRS symbols contains two DMRS symbols, l⁽¹⁾Is the index of the symbol 3.

The coding bit number frequency hopping splitting rule of each part of UCI (HARQ-ACK, CSI-part1 and CSI-part2) is as follows.

Frequency hopping splitting rule of HARQ-ACK coded bits:

suppose the number of encoding bits of HARQ-ACK is G^ACKIf the number of HARQ-ACK coded bits sent on hop1 and hop2 is:

G^ACK(2)＝G^ACK-G^ACK(1)。

frequency hopping splitting rule of CSI-part1 coded bits:

assume that the number of coded bits of CSI-part1 is G^CSI-part1Then, the number of CSI-part1 encoded bits sent on hop1 and hop2 is:

G^CSI-part1(2)＝G^CSI-part1-G^CSI-part1(1) (6)

when the minimum operation min (·,. cndot.) of the formula (4) is to the left of the comma, combining the formulas (5) and (6),

G^CSI-part1(1)≤G^CSI-part1(2) (7)

wherein the equal sign is only G^CSI-part1Can divide (2. N) completely_L·Q_m) This is true.

Frequency hopping splitting rule of CSI-part2 coded bits:

assume that the number of coded bits of CSI-part2 is G^CSI-part2Then, the number of CSI-part2 encoded bits sent on hop1 and hop2 is:

G^CSI-part2(1)＝M₁·N_L·Q_m-G^CSI-part1(1) (8)

G^CSI-part2(2)＝M₂·N_L·Q_m-G^CSI-part1(2) (9)

when the following three conditions exist in the UCI-only scene, there is a problem that transmission of CSI-part1 is incomplete.

Condition 1: the number of coded bits of CSI-part1 is exactly equal to the number of coded bits mapped by all REs capable of carrying data except reserved REs on hop1 and hop2 of PUSCH, namely the number of coded bits

Condition 2: g^CSI-part1Can not be divided completely (2. N)_L·Q_m). Therefore, the formula (7) cannot take an equal sign, i.e.

G^CSI-part1(1)<G^CSI-part1(2) (11)

Condition 3: the number of REs available to carry data for the two hopping resources is equal, i.e. for PUSCH hops 1 and hop2, there is M₁＝M₂(12)

As can be seen from the formulas (8), (9), (11) and (12),

G^CSI-part2(1)>G^CSI-part2(2) (13)

obtained by adding the equations (8) and (9),

G^CSI-part2(1)+G^CSI-part2(2)＝(M₁+M₂)·N_L·Q_m-G^CSI-part1(14)

from the formulae (14) and (10),

from the formulae (13) and (15),

from the formulae (16) and (4),

therefore, as can be seen from the formulae (9) and (17),

namely, the number of coding bits of the CSI-part1 on hop2 is greater than the number of coding bits mapped by the unreserved RE; whereas CSI-part1 is not carried with reserved REs. Therefore, the transmission of CSI-part1 is incomplete.

In addition, due to

(equation (17)), there may be a reserved RE without any data to send, as shown in fig. 4. If PUSCH is single carrier discrete fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM), the RE not transmitting any data may destroy the characteristic of peak-to-average power ratio (PAPR) of one or more symbols of hop 2.

In addition, the symbol referred to in the present application is a time unit, and may be an Orthogonal Frequency Division Multiplexing (OFDM) symbol.

It should be noted that, the number of bits of HARQ-ACK mentioned in this application refers to the number of information bits before HARQ-ACK is not encoded; the coding bit number of the HARQ-ACK means that the information bits of the HARQ-ACK are subjected to steps of channel coding and the like, and the bit number after redundant bits is increased.

In view of the above, the present application provides a communication method capable of solving the incomplete transmission of the CSI-part1, and further solving the problem that the single carrier characteristic is destroyed when a signal is transmitted on the hop2 by using the DFT-s-OFDM waveform.

As shown in fig. 5, the communication method includes:

and S510, receiving downlink control information, wherein the downlink control information is used for scheduling a PUSCH (physical uplink shared channel) which is only used for transmitting UCI (uplink control information), the PUSCH comprises a first frequency hopping resource and a second frequency hopping resource, and a time domain starting symbol of the first frequency hopping resource is positioned before a time domain starting symbol of the second frequency hopping resource.

The PUSCH is used only for carrying UCI refers to a UCI-only scenario defined in a communication protocol. The first and second frequency hopping resources are, for example, hop1 and hop2 described above. Optionally, the frequency domain resources of the first frequency hopping resource and the second frequency hopping resource may be different, where the difference indicates that the frequency domain resources of the first frequency hopping resource and the frequency domain resources of the second frequency hopping resource are partially overlapped or completely not overlapped. Further optionally, the time-frequency end position of the first frequency hopping resource is adjacent to the time-domain start position of the second frequency hopping resource. Or, the first frequency hopping resource is a resource which is continuous or discontinuous in the time domain, and the second frequency hopping resource is a resource which is continuous or discontinuous in the time domain. The interpretation of the hopping resources can be applied to other methods or embodiments in the present application.

It should be further noted that the PUSCH includes a first frequency hopping resource and a second frequency hopping resource, which means that when the network device indicates that the frequency hopping identifier field of the DCI of the uplink grant (UL grant) enables the PUSCH to perform frequency hopping, time-frequency domain resources of the PUSCH in the first hop and the second hop are respectively called the first frequency hopping resource and the second frequency hopping resource. In order to distinguish, the first frequency hopping resource and the second frequency hopping resource of the PUSCH in the present application have a precedence relationship in the starting timing sequence. In addition, the value of the number of coded bits mapped on a certain number of REs of the PUSCH is equal to the number of REs multiplied by the number of transmission layers of the PUSCH and further multiplied by the modulation order of the UCI potentially transmitted on the PUSCH.

The interpretation of the relevant terms in this application may refer to definitions in the communication protocol (subsection 6.2.7 of 3GPP TS38.212 v15.2.0).

In the following, an example of frequency hopping transmission provided by the present application is given.

Step one, the gNB configures a scale parameter α and a code rate compensation parameter for the UE through RRC signaling

And the parameters, wherein the scale parameter α is greater than 0 and less than or equal to 1, and the configuration mode of the code rate compensation parameter may be a set of values or a plurality of sets of values, if a set of values is configured, the set of values in the subsequent step is directly configured, and if a plurality of sets of values are configured, the index of the set of values can be indicated by Downlink Control Information (DCI) in the second step.

Step two: the gNB transmits DCI to the UE through the PDCCH, wherein the DCI comprises but is not limited to the following information: the PUSCH resources allocated to the UE, whether the PUSCH is UCI-only (or contains UL-SCH), whether the PUSCH is frequency hopped, the number of PUSCH transmission layers, and the modulation and coding strategyOutline index (I)_MCS) Number of PUSCH transmission layers N_L，And

Step three: after receiving DCI, UE analyzes PUSCH resources distributed to UE, whether PUSCH is UCI-only, whether PUSCH hops, and I_MCSNumber of PUSCH transmission layers N_LThe like; UE passing through I_MCSLooking up a table to obtain a code rate R and a modulation order Q_m(ii) a If there is DCI

Andthe UE resolves the index

And

and used in subsequent steps.

Step four, if the PUSCH analyzed by the UE is UCI-only, the bit number of the HARQ-ACK information required to be sent by the UE is not more than 2 (namely the bit number of the HARQ-ACK information is 0,1 or 2), and the UCI required to be sent by the UE comprises CSI-part1, the UE sends the HARQ-ACK information according to α,

R、Q_mAnd N_LObtaining HARQ-ACK coding bit number G by equal parameter calculation^ACKNumber of CSI-part1 coded bits G^CSI-part1Number of CSI-part2 coded bits G^CSI-part2. Optionally, the UCI may further include at least one of HARQ-ACK and CSI-part 2.

The manner in which the UE calculates the reserved REs is divided into the following two cases.

Case 1: the UCI does not include HARQ-ACK, or includes HARQ-ACK having the information bit number not greater than 2 (i.e., the HARQ-ACK information bit number is 0,1, or 2).

The UE calculates the number of reserved REs reserved for HARQ-ACK according to the following equation (2 in the denominator in the equation is calculated according to the HARQ-ACK information bit being 2):

wherein the content of the first and second substances,

number of REs l capable of carrying UCI on symbol l of PUSCH₀Index for a first DMRS-free symbol after a first set of consecutive DMRS symbols for PUSCH;

is the number of symbols of the PUSCH.

Then according to the resulting Q'_ACKTo calculate the number of coded bits mapped by the reserved REs that may need to be reserved for HARQ-ACK

Case 2: UCI includes HARQ-ACK with information bit number greater than 2, then

Step five: if the UE needs frequency hopping for resolving the PUSCH, the UE respectively calculates the encoding bit numbers of the HARQ-ACK, the CSI-part1 and the CSI-part2 on the hop1 and the hop2 according to the following formula.

G^ACK(2)＝G^ACK-G^ACK(1)。

Wherein, when the number of HARQ-ACK bits is greater than 2,

or, the above G^CSI-part1(1) The formula can also be calculated in the form of the following piecewise function:

when the number of HARQ-ACK information bits is 0,1 or 2,

when the number of HARQ-ACK information bits is greater than 2,

G^CSI-part1(2)＝G^CSI-part1-G^CSI-part1(1)。

G^CSI-part2(1)＝M₁·N_L·Q_m-G^CSI-part1(1)。

G^CSI-part2(2)＝M₂·N_L·Q_m-G^CSI-part1(2)。

the UE respectively calculates the number of coded bits mapped by reserved REs reserved for HARQ-ACK on hop1 and hop2 according to the following formula:

step six: and the UE maps the HARQ-ACK, CSI-part1 and CSI-part2 coded bits to the PUSCH according to the parameters obtained by calculation in the step five.

The following describes advantageous effects of calculating the number of mapping code bits on two hops by using the communication method 500 provided in the present application for frequency hopping transmission by using several examples. Table 1 shows the results obtained using the prior art process and table 2 shows the results obtained using the process of the present application.

TABLE 1

As can be seen from the second last row and the third last row in table 1, the number of encoding bits that the unreserved REs on hop2 can map is different from the number of encoding bits that the CSI-part1 maps on the unreserved REs, and it can be seen that CSI-part1 cannot be completely carried by the unreserved REs on hop2, which may cause incomplete CSI-part1 transmission; as can be seen from the first to last and fourth to last rows of Table 1, the number of coded bits of the reserved RE mapping of hop2

The number of coded bits is larger than that of the code bits mapped by the CSI-part2 on the hop2, and it can be seen that some reserved REs have no data to transmit, and when the PUSCH uses DFT-s-OFDM, the single carrier low PAPR characteristic of the PUSCH can be damaged.

The above examples are merely illustrative.

Table 2 shows the results of calculation by using the communication method provided in this application, and as can be seen from the second last row and the third last row in table 2, the number of coded bits transmitted by the unreserved REs on hop2 is the same as the number of coded bits mapped on the unreserved REs by CSI-part 1. As can be seen from the first to last and fourth to last rows of Table 2, the number of coded bits for the reserved RE mapping of hop2

And the number of coded bits is less than that of the code bits mapped on the hop2 by the CSI-part2, and all reserved REs have data to transmit. It can be seen that the calculation method of the present application aligns the number of coded bits mapped by the unreserved REs in the two hops and the number of coded bits of CSI-part1 in the two hops, respectively, and solves the problems of the prior art.

TABLE 2

In the prior art, when there is UCI and UL-SCH transmission on PUSCH simultaneously, i.e., in a non-UCI-only scenario, UCI includes one or more of HARQ-ACK, CSI-part1 and CSI-part2, and the coded bit lengths are G respectively^ACK、G^CSI ^-part1And G^CSI-part2。

For frequency hopping of PUSCH, the splitting rules of the code bit number of each of the CSI-part1 and CSI-part2 in hop1 and hop2 are as follows:

if UCI contains HARQ-ACK, the splitting rule of the coding bit number of the HARQ-ACK on hop1 and hop2 is as follows:

In a non-UCI-only scene in the prior art, the number of coded bits mapped on the second hopping resource by the CSI-part1 is small, that is, the number of REs used for mapping the CSI-part1 on the second hopping resource is small, so that the CSI-part1 cannot be mapped on the second hopping resource completely, the scheme provided by the application increases the number of coded bits mapped on the first hopping resource by the CSI-part1 and reduces the number of coded bits mapped on the second hopping resource by the CSI-part1, compared with the prior art, thereby solving the problem that the CSI-part1 is not completely transmitted due to UCI transmission through frequency hopping in the non-UCI-only scene.

Step two: the gNB transmits DCI to the UE through the PDCCH, wherein the DCI comprises but is not limited to the following information: the PUSCH resources allocated to the UE, whether the PUSCH is UCI-only (or contains UL-SCH), whether the PUSCH is frequency hopped, the number of PUSCH transmission layers, and a modulation and coding strategy index (I)_MCS) Number of PUSCH transmission layers N_L，
