Description

Information transmission method, terminal equipment and network equipment

Technical Field

The present invention relates to the field of communications, and more particularly, to an information transmission method, a terminal device, and a network device.

Background

According to the fifth generation mobile communication 5G New Radio (NR) technology, when a multiplexing timing relationship is satisfied by a plurality of overlapped physical uplink control channels (Physical Uplink Control Channel, PUCCH) or a plurality of PUCCHs and physical uplink shared channels (Physical Uplink Shared Channel, PUSCH), the method can be multiplexed into one channel for transmission; if the multiplexing timing relationship is not satisfied, the terminal device determines that the overlap condition is an abnormal condition. Here, the timing relationship is mainly to ensure that the terminal device has enough time to determine whether the information carried by different uplink channels needs multiplexing and the time required for concatenation, encoding, etc. of uplink control information (Uplink Control Information, UCI) at the time of multiplexing transmission.

Currently, to better support Ultra high reliability low latency communication (Ultra-reliable low latency, URLLC) services, physical channels may be configured with 2-level priority (2-level priority), i.e., high-priority (HP) and low-priority (LP). Typically, the URLLC traffic will be transmitted using a high priority channel, if there are multiple uplink channels of different priorities overlapping, for the same priority channel, the terminal may determine a multiplexed channel, if there is only one of the priority channels, the multiplexed channel is the channel itself; if the multiplexing channels with different priorities are overlapped, the terminal only transmits the multiplexing channel with high priority, and discards the multiplexing channel with low priority. It can be seen that such a processing mechanism guarantees the latency requirements of the high priority channels by sacrificing the transmission efficiency of the low priority channels.

In this case, whether the influence of the high priority channel transmission on the low priority channel transmission can be reduced on the premise of meeting the time delay and reliability requirements of the high priority information is a problem that needs to be studied currently.

In order to clearly illustrate the ideas of the embodiments of the present application, a brief description will be first given of the processing manner when channels overlap in a communication system.

In the NR system, when a multiplexing timing relationship is satisfied by a plurality of PUCCHs or a plurality of PUCCHs and PUSCHs that overlap, transmission can be multiplexed in one channel. Specifically, when the multiplexing timing is satisfied, first the terminal determines a set Q of overlapping PUCCH channels:

1. determining PUCCH a: starting the earliest PUCCH in the overlapping channels; if a plurality of PUCCHs with the same starting positions exist, taking the PUCCH with the longest duration; if the starting position and the duration are the same, one of the starting position and the duration can be selected as PUCCH A;

2. incorporating PUCCH overlapping PUCCH a into set Q;

3. incorporating a PUCCH overlapping any one PUCCH of set Q into set Q;

4. multiplexing all UCIs in the set Q into one PUCCH, and determining PUCCH B according to the UCI bit number and physical uplink control channel resource indication (PUCCH resource indicator, PRI);

5. and determining whether the PUCCH B overlaps with other PUCCHs, and if so, repeating the steps 1-4.

After determining the overlapped PUCCH channel set Q, the terminal determines a PUCCH for multiplexing UCI carried in channels in the transmission set Q according to the set Q, wherein if the PUCCH is not overlapped with any PUSCH (time domain overlapping), the terminal multiplexes UCI information into the PUCCH for transmission; if the PUCCH overlaps with at least one PUSCH, the terminal determines one PUSCH from the at least one PUSCH, and multiplexes UCI information into the PUSCH for transmission, where positive acknowledgement ACK/negative acknowledgement NACK information and channel state information (Channel State Information, CSI) carried in a channel in the set Q may be multiplexed for transmission in the PUSCH; the scheduling request (Scheduling Request, SR) information carried within the channels in set Q is not transmitted.

Wherein, the process of determining one PUSCH from at least one PUSCH by the terminal may include:

1. if at least one PUSCH includes a first PUSCH scheduled by downlink control information (Downlink Control Information, DCI) and a second PUSCH configured by higher layer signaling (e.g., configured grant configuration or semipersistent on PUSCH), determining the PUSCH as one of the first PUSCHs;

2. if the plurality of PUSCHs satisfy the multiplexing condition, the terminal selects, as the specific PUSCH, a PUSCH having a preceding time in a carrier having a smallest corresponding serving cell ID (e.g., servCellIndex) among the plurality of PUSCHs.

And then, when the UCI is multiplexed in the PUSCH carrying the data for transmission, determining the number of modulation symbols occupied by the UCI in the PUSCH according to the number of bits of the UCI and the configuration information of the PUSCH. Specifically, the following cases may be included:

if the UCI includes ACK/NACK information, the number of modulation symbols Q 'occupied by the UCI within the PUSCH' _ACK Can be calculated according to the following formula 1:

if the UCI includes CSI part 1 (part 1 in CSI), the number of modulation symbols Q 'occupied by UCI within the PUSCH' _CSI-1 Can be calculated according to the following formula 2:

wherein:

-O _ACK the number of ACK/NACK information;

-if O _ACK ≥360，L _ACK =11; otherwise L _ACK For the number of cyclic redundancy check (Cyclic Redundancy Check, CRC) bits;

-O _CSI-1 the information quantity is CSI part 1;

-if O _CSI-1 ≥360,L _CSI-1 =11; otherwise L _CSI-1 For the number of CRC bits;

-

or (b)

Configured by high-level signaling;

-C _UL-SCH the number of code blocks included in the PUSCH data part;

-K _r the size of the coding block is the r;

-

the number of subcarriers occupied by the PUSCH;

-

the number of subcarriers occupied by PTRS in an orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol/within the resources occupied by PUSCH;

-

the number of resource elements used for transmitting UCI in OFDM symbol/within the resources occupied for PUSCH,

the total number of OFDM included in the PUSCH;

for OFDM symbols carrying DRMS in PUSCH,

for OFDM symbols in PUSCH that do not carry DRMS,

- α is configured by higher layer signaling scaling;

-l ₀ a symbol index (index) for the first OFDM symbol in PUSCH not used for transmission of demodulation reference symbols (Demodulation Reference Symbol, DMRS);

-

for the number of modulation symbols used for ACK/NACK information and/or configuration grant-uplink control information (Configured grant uplink control information, CG-UCI) transmitted in the PUSCH, wherein, when ACK/NACK information is transmitted in the PUSCH,

namely the number of modulation symbols used for transmitting ACK/NACK information in the PUSCH; when CG-UCI is transmitted in the PUSCH,

I.e. the number of modulation symbols used for transmitting CG-UCI in the PUSCH.

In addition, when UCI is multiplexed into PUSCH that does not carry data for transmission, the number of modulation symbols occupied by UCI in PUSCH needs to be determined according to the number of bits of UCI and configuration information of PUSCH. Specifically, if UCI includes ACK/NACK information, the number of modulation symbols Q 'occupied by UCI in the PUSCH' _ACK Can be calculated according to the following formula 3:

wherein R is the coding rate of PUSCH; q (Q) _m Is the modulation order of PUSCH; the other parameters are as defined above.

Here, in order to guarantee reliability of ACK/NACK information, the ACK/NACK information is mapped from the first OFDM symbol that does not carry DMRS after the earliest DMRS symbol in PUSCH, occupying Q' _ACK Each resource unit RE (resource elements) is transmitted with one modulation symbol mapped to one RE, and thus the number of modulation symbols is equal to the number of REs.

The above describes that when the PUCCH overlaps the PUSCH and satisfies the multiplexing timing relationship, the PUCCH can be multiplexed into one channel for transmission, and describes a mechanism for multiplexing UCI information into the PUSCH for transmission, and a calculation manner of the number of modulation symbols occupied by UCI in the PUSCH during transmission is given.

As described above, in order to better support ultra-high reliability low latency communication URLLC traffic, the physical channels may be configured with 2-level priorities, i.e., high priority and low priority, typically the URLLC traffic is transmitted using a high priority channel. Further, if there are a plurality of uplink channels with different priorities overlapping, the terminal may determine one multiplexing channel for a plurality of channels with high priority (if only one channel with the priority is used, the channel itself is determined as the multiplexing channel), and similarly may determine one multiplexing channel for a plurality of channels with low priority, the terminal may obtain two multiplexing channels, corresponding to different priorities. As specified, if the multiplexed channels of different priorities overlap, the terminal will transmit only the high priority multiplexed channel and discard the low priority multiplexed channel. Thus, although the time delay and reliability of the high priority channel are guaranteed, the transmission efficiency of the low priority channel is also affected.

In order to reduce the influence on the transmission of the low priority channel as much as possible on the premise that the time delay and the reliability of the high priority information are ensured, multiplexing different priority information in the same uplink channel for transmission can be considered. However, if the carrying capacity of the selected multiplexing channel is limited, multiplexing information with different priorities for transmission therein tends to cause performance degradation of high-priority information, resulting in time delay and poor reliability of the high-priority information, and affecting overall performance of the system.

To this end, an embodiment of the present application proposes an information transmission method, applied to a terminal device, with reference to fig. 2, the method includes:

s101, if a physical uplink control channel PUCCH and a physical uplink shared channel PUSCH are overlapped, wherein the priority of the PUCCH is different from that of the PUSCH, the PUCCH is configured to be used for bearing uplink control information UCI, and the number of first modulation symbols obtained according to the number of UCI bits is larger than the maximum number of modulation symbols which can be used for bearing the UCI in the PUSCH, the terminal equipment transmits the channel with higher priority in the PUCCH and the PUSCH.

According to the embodiment of the present application, if the PUCCH overlaps with the PUSCH and the priorities are different, for example, the PUCCH is high priority, the PUSCH is low priority, or the PUCCH is low priority, and the PUSCH is high priority, the terminal device transmits a channel with a higher priority in the overlapping channels if a specified condition is met, where the specified condition is: the number of first modulation symbols obtained according to the number of bits of the uplink control information UCI is greater than the maximum number of modulation symbols available for carrying UCI in the PUSCH. By using the embodiment of the application, the requirements of low time delay and high reliability of high-priority information transmission can be ensured, and the influence of high-priority channel transmission on low-priority channel transmission is reduced.

Correspondingly, an embodiment of the present application provides an information transmission method, applied to a network device, referring to fig. 3, the method includes:

s201, if a physical uplink control channel PUCCH and a physical uplink shared channel PUSCH overlap, where priorities of the PUCCH and the PUSCH are different, the PUCCH is configured to carry uplink control information UCI, and the number of first modulation symbols obtained according to the number of UCI bits is greater than the maximum number of modulation symbols available for carrying the UCI in the PUSCH, then the network device receives a channel with a higher priority in the PUCCH and the PUSCH.

According to an embodiment of the present application, optionally, the PUSCH has a higher priority than the PUCCH, and the terminal device transmits the PUSCH and does not transmit the UCI. Correspondingly, the network device receives the PUSCH and does not receive the UCI.

It can be seen that, with the embodiments of the present application, if the PUCCH overlaps with the PUSCH, and if the PUCCH is of low priority and the PUSCH is of high priority, the specified condition is met, that is, the number of first modulation symbols corresponding to UCI is greater than the maximum number of modulation symbols available for carrying UCI in the PUSCH, which indicates that the capability of carrying UCI by the PUSCH is insufficient to meet the performance requirement (such as the reliability requirement) of UCI, in this case, the terminal device transmits the PUSCH of high priority, and discards transmitting the UCI, thereby ensuring that the low latency and the high reliability requirement of high priority information transmission are met, and reducing the influence of high priority channel transmission on low priority channel transmission.

According to the embodiment of the application, optionally, for the case that the PUCCH is high priority and the PUSCH is low priority, the PUCCH is used for carrying UCI, so that the terminal device transmits the PUCCH with high priority, and can carry UCI through the PUCCH with high priority to complete uplink transmission of UCI, that is, the requirements of low delay and high reliability of high priority information can be met.

It can be seen that, here, since PUSCH is of low priority, i.e. PUSCH is not a channel for preferential transmission, the capability size of PUSCH to carry UCI may not be considered, that is, whether or not the aforementioned specified conditions are met, the terminal device may not preferentially transmit PUSCH, but may preferentially transmit PUCCH of high priority for carrying UCI.

According to an embodiment of the present application, optionally, if the first number of modulation symbols is less than or equal to the maximum number of modulation symbols available for carrying the UCI in the PUSCH, the terminal device multiplexes the UCI in the PUSCH for transmission, and correspondingly, the network device receives the PUSCH.

It can be seen that, with the embodiment of the present application, if the number of the first modulation symbols corresponding to UCI is less than or equal to the maximum number of modulation symbols available for carrying UCI in the PUSCH, that is, the capability of carrying UCI by the PUSCH does not meet the foregoing specified condition, which indicates that the capability of carrying UCI by the PUSCH can meet the performance requirement (such as the reliability requirement) of UCI, in this case, the terminal device does not discard the UCI for transmission any more, but multiplexes UCI into the PUSCH with high priority for transmission, which can meet the low latency and high reliability requirement of high priority information transmission, and reduce the influence of high priority channel transmission on low priority channel transmission.

According to an embodiment of the present application, optionally, the number of modulation symbols occupied by the UCI in the PUSCH is equal to the first number of modulation symbols.

According to an embodiment of the present application, optionally, if the first modulation symbol number obtained according to the UCI bit number is greater than the maximum number of modulation symbols available for carrying the UCI in the PUSCH, the following processing may be further performed:

compressing the UCI, wherein the number of modulation symbols corresponding to the compressed UCI is smaller than or equal to the maximum number of modulation symbols which can be used for bearing the UCI in the PUSCH;

and the terminal equipment multiplexes the compressed UCI into the PUSCH for transmission.

It can be seen that, in the embodiment of the present application, the UCI occupation capacity can be reduced by a compression manner, so that the UCI can be multiplexed into the PUSCH for transmission, thereby meeting the transmission performance requirement and reducing the influence of the high-priority channel transmission on the low-priority channel transmission.

According to an embodiment of the present application, optionally, the first modulation symbol number is obtained according to the number of bits of the UCI, a parameter related to transmission of the PUSCH, and a first scaling factor corresponding to the PUSCH.

Optionally, according to an embodiment of the present application, the parameters related to the transmission of the PUSCH include at least one of:

The coding rate of the PUSCH and the modulation scheme of the PUSCH;

the number of transport block bits carried in the PUSCH and the number of first resource elements REs included in the PUSCH;

According to an embodiment of the present application, optionally, the maximum number of modulation symbols in the PUSCH that can be used to carry the UCI is determined according to at least one of the following parameters:

a second scaling factor corresponding to the PUSCH;

the number of first resource elements REs included in the PUSCH, the first REs not being used for transmission of DMRS or PTRS.

According to an embodiment of the present application, optionally, the value of the second scaling factor is greater than 0 and less than or equal to 1.

According to an embodiment of the present application, optionally, the first modulation symbol number obtained according to the number of bits of UCI is denoted as Q _beta The first modulation symbol number Q _beta The physical meaning of (c) can be understood as: a number of modulation symbols required for carrying UCI obtained from a coding rate configured according to reliability requirements and the number of UCI bits to be transmitted, a first number of modulation symbols Q _beta In the embodiment of the present application, the first modulation symbol number Q _beta The value of (a) may be the first term of the two term calculation formulas of the minimum value operation in the foregoing formulas (each formula corresponds to a plurality of cases respectively), that is, the first term of the bracket of the min { } operation in the formulas.

According to an embodiment of the present application, optionally, the UCI includes at least one of the following information: positive acknowledgement information ACK, negative acknowledgement information NACK, channel state information CSI.

The implementation manner of the information transmission method according to the embodiment of the present application is described above by the embodiment, and the specific implementation process of the embodiment of the present application is described below by various cases and various specific examples in various cases.

I. Case one: the high-priority HP UCI is multiplexed into the low-priority LP PUSCH for transmission.

Referring to fig. 4, where at least one HP PUCCH overlaps with an LP PUSCH, UCI carried in the HP PUCCH is multiplexed into the LP PUSCH for transmission.

If the first modulation symbol number Q is obtained according to the HP UCI bit number _beta Greater than the maximum number Q of modulation symbols available for carrying HP UCI in the LP PUSCH _max UCI is transmitted through the HP PUCCH, and the LP PUSCH is not transmitted.

As previously described, the first modulation symbol number Q _beta The value of (2) may be the first term of the two term of the minimum operation in the above formulas, i.e. the first term of the bracket of the min { } operation in each formula, where different formulas correspond to different application situations.

Specifically, a first modulation symbol number Q _beta Can be determined according to at least one of the following parameters:

1) The number of bits of the HP UCI;

2) Scaling factor indicated by network device such as base station

3) Coding rate and modulation mode of PUSCH; or, the amount of data (the number of transmission block bits or the number of coding block bits) carried in the PUSCH and the number of first resource elements REs included in the PUSCH, the first REs being not used for transmission of DMRS or PT-RS.

Correspondingly, the maximum number Q of modulation symbols for carrying HP UCI _max The physical meaning of (a) can be understood as the maximum number of modulation symbols that can transmit the HP UCI in the LP PUSCH obtained according to the scaling factor alpha configured by the base station, Q _max The value of (2) may be the second term of the two term of the minimum operation in the above formulas, that is, the second term of the bracket of the min { } operation in each formula, where different formulas correspond to different application situations.

Specifically, the maximum number Q _max Can be determined according to at least one of the following parameters:

1) A scaling factor α indicated by a network device, such as a base station;

2) The first resource element RE number included in the PUSCH is not used for transmitting the DMRS or the PT-RS.

Then the O is taken _ACK Bit ACK/NACK information is multiplexed into LP PUSCH by

Transmitting the modulation symbols; otherwise, the terminal transmits the O through the HP PUCCH _ACK Bit ACK/NACK information, and not transmitting the LP PUSCH, wherein the meaning of each parameter is referred to in the foregoing description.

Example 2

In the present embodiment, bearer O _ACK The HP PUCCH of the bit ACK/NACK information overlaps with the LP PUSCH that does not carry data, where if

In the embodiment of the present application, the base station aims at the LP PUSCH configuration α to limit the resources for transmitting UCI in PUSCH, if the resources occupied by UCI are excessive, then the remaining resources for transmitting uplink data are less, and at this time, the performance of transmitting uplink data cannot be guaranteed, so that the time of transmission may become an invalid transmission.

When the capability of carrying the HP UCI (for example, the capacity of carrying the UCI) in the LP PUSCH can meet the performance requirement (for example, the reliability requirement) of the HP UCI, multiplexing the HP UCI into the LP PUSCH for transmission, ensuring the performance of carrying the data in the LP PUSCH and the performance of the HP UCI, and at the moment, the multiplexing transmission is beneficial to reducing the influence of the high-priority channel transmission on the low-priority channel transmission and improving the system transmission efficiency.

When the capability of carrying the HP UCI in the LP PUSCH (for example, the capacity of the carrying UCI) cannot meet the performance requirement (for example, the reliability requirement) of the HP UCI, the transmission of the HP UCI should be preferentially guaranteed (no compression transmission), while the transmission of the LP PUSCH is discarded, and the transmission efficiency at this time is not affected by other factors.

The first modulation symbol number Q referred to in the embodiment of the present application _beta And said maximum number Q _max The value of (2) can be judged and calculated based on the existing related parameters, and no additional complex calculation logic is required to be introduced, which is beneficial to the realization of the terminal application.

II. Case 2: the low-priority LP UCI information is multiplexed into the high-priority HP PUSCH for transmission.

Referring to fig. 5, where at least one LP PUCCH overlaps with HP PUSCH, UCI carried in the LP PUCCH is multiplexed into HP PUSCH for transmission.

If the first modulation symbol number Q is obtained according to the LP UCI bit number _beta Greater than the maximum number Q of modulation symbols available for carrying LP UCI in the HP PUSCH _max There are two ways in which the processing may be performed, each of which is described in detail below.

A. The processing method is that the LP UCI is compressed, for example, partial information is discarded or a plurality of information are combined, the compressed information is multiplexed in the HP PUSCH for transmission, and the number of modulation symbols corresponding to the compressed information is smaller than or equal to the maximum number Q _max 。

It can be seen that, in this embodiment, when the capability of carrying LP UCI in the HP PUSCH (for example, the capacity of carrying UCI) cannot meet the performance requirement (for example, the reliability requirement) of the HP UCI, on the premise of ensuring the performance of the HP PUSCH, the LP UCI is properly compressed and transmitted, and the LP PUCCH is discarded, so that the performance of high-priority information transmission can be ensured, which is favorable for reducing the influence of high-priority channel transmission on low-priority channel transmission, and improving the transmission efficiency of the system.

B. Another processing way is to transmit only the HP PUSCH without transmitting the LP UCI.

In this embodiment, when the capability of carrying LP UCI in the HP PUSCH (for example, the capacity of carrying UCI) cannot meet the performance requirement (for example, the reliability requirement) of the HP UCI, the performance of the HP PUSCH is ensured, and the LP PUCCH is abandoned, so that a compression processing mechanism is not required to be introduced, and the terminal is convenient to implement quickly.

Example 3

Then the O is taken _ACK Bit ACK/NACK information is multiplexed into HP PUSCH by

The transmission of the modulation symbols is carried out, wherein the meaning of each parameter is referred to in the previous description; otherwise, the ACK/NACK information is compressed to obtain O' _ACK Bits, and

then the O 'is' _ACK Bit ACK/NACK information multiplexing into HP PUSCH by

The transmission is performed by means of modulation symbols, wherein the meaning of the parameters is referred to in the foregoing description.

Example 4

Then the O is taken _ACK Bit ACK/NACK information multiplexing into HP PUSCH by

The transmission of the modulation symbols is carried out, wherein the meaning of each parameter is referred to in the previous description; otherwise, not transmitting the LAnd P UCI only transmits the HP PUSCH.

In the above embodiments of the present application, the first modulation symbol number Q is referred to _beta And said maximum number Q _max The value of (2) can be judged and calculated based on the existing related parameters, and no additional complex calculation logic is required to be introduced, so that the terminal can be quickly realized in application.
