The technical solutions provided in the present application will be described in detail below with reference to the drawings.

In order to facilitate understanding of the embodiments of the present application, the following briefly introduces several concepts involved in the present application.

1.Time slot and time domain symbols

A time slot can be understood as a part of serial self-multiplexing of time slot information dedicated to a single channel. A time slot can be understood as a channel.

In the embodiment of the present application, the symbol is also referred to as a time-domain symbol, and may be an orthogonal frequency division multiple (OFDM) symbol, or a single carrier frequency division multiple access. (SC-FDMA) symbol, of which SC-FDMA is also known as orthogonal frequency division multiplexing (OFDM) with conversion precoding (transform precoding, OFDM with TP).

In addition, a time domain symbol can also be understood as a time unit. For example, a time unit can be one or more subframes; or it can be one or more time slots; or it can be one or more symbols. When a time unit is a symbol, in the description of the embodiment of the present application, the time domain symbol and the time unit may be equivalent.

2. Physical uplink channel

It can be used to carry uplink control information and / or uplink data. For example, the physical uplink channel may include a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH) defined in the LTE protocol or the NR protocol, and a physical uplink control channel (PUSCH) defined as the network evolves. Other uplink channels for the above functions.

3. Downlink control information (download control information, DCI)

It is mainly used to send downlink scheduling allocation information. There are many different formats, including but not limited to DCI format 0-0, 0-1, 1-0, 1-1, 2-0, 2-1, 2-2, 2-3.

4.PUCCH resource indication field or PUCCH resource indication field (PUCCH resource indicator field)

The M bit information field in the DCI is used to indicate transmission resources available for HARQ-ACK information. Optionally, M is equal to 3.

Hereinafter, the uplink control information (uplink control information) (UCI) of the transmission target according to the embodiment of the present application will be described in detail.

In the embodiment of the present application, the uplink control information UCI includes a hybrid automatic repeat request response message (hybrid, automatic repeat request, HARQ-ACK), scheduling request (scheduling request, SR), and CSI (CQI, PMI, RI) At least one.

By way of example and not limitation, in the embodiments of the present application, the uplink control information may include, but is not limited to, one or more of the following information:

Feedback information

In the embodiment of the present application, the uplink control information may include feedback information for downlink data.

Specifically, in the embodiments of the present application, the transmission of downlink data may adopt a feedback technology, which is used as an example and not a limitation. The feedback technology may include, for example, a hybrid automatic repeat request (HARQ) technology.

Among them, HARQ technology is a technology formed by combining forward error correction (FEC) and automatic repeat request (ARQ).

For example, in HARQ technology, after receiving data from a transmitting end, the receiving end can determine whether the data is accurately decoded. If the decoding cannot be performed accurately, the receiving end can feed back negative-acknowledge (NACK) information to the sending end. Therefore, based on the NACK information, the sending end can determine that the receiving end has not accurately received the data and can perform retransmission processing; If the decoding can be accurately performed, the receiving end can feedback acknowledgement (ACK) information to the transmitting end, so that the transmitting end can determine that the receiving end accurately receives data based on the ACK information, and thus can determine that the data transmission is completed.

That is, in the embodiment of the present application, when the receiving end decodes successfully, it can send ACK information to the sending end, and when decoding fails, it can feed back NACK information to the sending end.

By way of example and not limitation, in the embodiments of the present application, the uplink control information may include ACK information or NACK information in HARQ technology. Among them, HARQ-ACK is used to feedback the reception of the downlink data channel PDSCH. When the UE receives correctly, it sends an ACK. When the UE receives an error, it sends a NACK. The base station determines the next scheduling strategy, such as retransmission or new transmission, according to the feedback information of the UE to the PDSCH channel.

It should be understood that the above-mentioned feedback information includes only exemplary descriptions, and this application is not limited to this. Other information that can indicate the terminal device's reception of downlink data falls within the protection scope of this application, such as The feedback information may further include discontinuous transmission (DTX) information, and the DTX information may be used to indicate that the terminal device has not received downlink data.

2. Channel state information CSI

In the field of wireless communications, the so-called CSI is the channel attributes of the communication link. CSI is the channel state information fed back to the base station by the UE after measuring the channel state. The information further includes information such as CQI / PMI / RI. It describes the signal's attenuation on each transmission path, that is, the value of each element in the channel gain matrix H, such as signal scattering, environmental degradation (multipath, fading, or shadowing), distance attenuation (power attenuation). ) And other information. CSI can adapt the communication system to the current channel conditions and provide a guarantee for high-reliability and high-speed communication in a multi-antenna system.

3. Channel quality indicator (CQI) information

In the embodiment of the present application, the CQI may be used to reflect the channel quality of a physical downlink shared channel (PDSCH). CQI is channel quality indication information and is used to directly feedback channel quality. The base station may further determine a modulation coding strategy (MCS) used for sending data according to the CQI. When the value of the feedback CQI is high, a higher coding modulation method and a higher code rate can be used to carry more information on limited resources, thereby improving the data transmission rate. When the value of the feedback CQI is low, a lower coding modulation mode and a lower code rate can be used, and more time-frequency resources are used to transmit data, thereby improving the reliability of data transmission. At the same time, by measuring the CQI of different frequency domain resources, the UE enables the base station to schedule data on frequency domain resources with good channel quality, thereby obtaining frequency domain scheduling gain.

By way of example and not limitation, in the embodiment of the present application, the channel quality of the PDSCH may be represented by 0 to 15. 0 means the worst channel quality, 15 means the best channel quality.

In the embodiment of the present application, the terminal device may send the CQI information to the network device on a PUCCH or a physical uplink shared channel (physical uplink shared channel (PUSCH)). The network device can determine the current PDSCH or PUSCH wireless channel conditions based on the CQI information, and then complete PDSCH scheduling. For example, in the embodiment of the present application, the network device can determine adaptive coding and modulation based on the CQI information. AMC), modulation and coding scheme (MCS), code rate or data amount for uplink transmission or downlink transmission, and so on.

4. Rank indication (RI) information

In the embodiment of the present application, RI is rank indication information, and is used to feed back to the base station the number of layers that can be separated from the channel. The larger the number of layers, the larger the amount of data that can be transmitted simultaneously. The RI information may be used to indicate the number of valid data layers of the PDSCH, or in other words, the RI information may be used to indicate the number of codewords (CW) that the terminal device can currently support.

5. Precoding matrix indicator (PMI) information

In the embodiment of the present application, the PMI information may be used to indicate an index of a codebook set, and the PMI is a precoding matrix identifier of transmission data that the UE feeds back to the base station according to the measured channel quality. The base station may determine the corresponding precoding matrix according to the feedback PMI information. That is, in using multiple antenna technology, for example, multiple-input multiple-output (MIMO) technology, in baseband processing, precoding processing based on a precoding matrix (precoding) is performed. The terminal device can indicate the precoding matrix through the PMI information, thereby improving the signal quality of the PDSCH.

In addition, there is some information such as CSI-RS resource indicator (CSI-RS resource indicator), which is used to feed back the measurement to the base station, which measurement resource has the best channel quality measurement.

It should be understood that the specific contents of the CSI listed above are merely exemplary descriptions, and should not be construed as limiting the present application in any way. The CSI sent by the receiving-end device to the sending-end device may include one or more of the above-mentioned enumerations, or may include other information used to characterize CSI in addition to the above-mentioned enumeration, which is not limited in this application.

In the embodiment of the present application, sending uplink control information may refer to sending data or information carried on an uplink control channel PUCCH or an uplink shared channel PUSCH, where the data or information may refer to data or information after channel coding. This application does not limit this.

Similarly, in the embodiment of the present application, sending downlink control information may refer to sending data or information carried on a downlink control channel PDCCH or a downlink shared channel PDSCH, where the data or information may refer to data or information after channel coding. information. This application does not limit this.

In the following, without loss of generality, the embodiment of the present application will be described in detail by taking an interaction process between a terminal device and a base station as an example. The terminal device may be any terminal device that has a wireless connection relationship with one or more network devices in a wireless communication system. It can be understood that any terminal device in the wireless communication system can implement wireless communication based on the same technical solution. This application does not limit this.

In the 5G system, the format of PUCCH and corresponding rules are shown in Table 1 below. As can be seen from Table 1 below, the resources of PUCCH format 2, format 3, and format 4 can support mixed transmission of HARQ, CSI, and SR. In the present application, a PUCCH resource whose number of symbols included in the PUCCH is less than or equal to a preset constant N ₁ is referred to as a short form PUCCH, and a PUCCH resource whose number of symbols is greater than or equal to the preset constant N ₂ is referred to A PUCCH in a short format is called a PUCCH in a long format. Among them, N ₁ and N ₂ are positive integers, and the values of N ₁ and N ₂ may be the same or different.

It should be understood that the preset constants N ₁ and N ₂ may be constants configured by higher layer signaling or constants configured by physical layer signaling. In the embodiments of the present application, the high-level signaling may be radio resource control (RRC) signaling or MAC layer signaling; the physical layer signaling may be DCI. The application does not limit the configuration of the preset constants.

For example, in 5G, the value of N ₁ may be two. A PUCCH in short format can refer to a PUCCH that includes one or two symbols, such as PUCCH format 2 and PUCCH format 0; the value of N ₂ can be 4, and a PUCCH in long format can refer to the number of symbols included. Fourteen PUCCHs, for example, PUCCH Format 1, Format 3, and Format 4. In the embodiment of the present application, the PUCCH in the short format may be PUCCH format 2, and the PUCCH in the long format may be PUCCH format 1, format 3, and format 4.

Table 1

Specifically, the resources used for transmitting HARQ-ACK are dynamically indicated by the base station. First, the base station configures one or more resource sets (resource sets) for the terminal device, and the range of the number of UCI information bits carried by different resource sets is different. The base station and the terminal device determine a resource set from one or more resource sets according to the total number of bits of HARQ-ACK information that the terminal device needs to feed back, and then according to the HARQ in the DCI signaling issued by the base station -The resource indicator field (resource indicator field) of the ACK information feedback determines that one resource in the resource set carries HARQ-ACK information.

FIG. 2 is a schematic diagram of a resource selection process in an uplink transmission process according to an embodiment of the present application. Specifically, in one time unit, the one PUCCH resource determined by the base station to carry HARQ-ACK may be a short format in which the number of OFDM symbols is less than or equal to two symbols, such as PUCCH format 2, for carrying a CSI report # The PUCCH of 1 may be a short format, such as PUCCH format 2. In this time unit, the PUCCH resource carrying the HARQ-ACK information and the PUCCH resource carrying the CSI information may have an overlap area in the time domain. It should be understood that the overlap here may be a partial overlap or a full overlap. It should also be understood that a time unit here may be a slot or a time window.

As shown in FIG. 2, the PUCCH format 2 carrying the HARQ-ACK information and the PUCCH format 2 carrying the CSI report # 1 have a partially overlapping area in the time domain. In this case, the base station may re-select a resource set according to the range of the information bits in the above-mentioned resource set according to the HARQ-ACK information and the total number of information bits reported by the CSI required by the terminal device. A new PUCCH is determined from the resource set reselected through the resource indication field in the DCI signaling.

Alternatively, as shown in another example of resource selection in the uplink transmission process shown in FIG. 3, when a PUCCH resource carrying HARQ-ACK information is simultaneously overlapped with a PUCCH carrying CSI information and a PUCCH carrying SR information in the time domain, the base station may According to the required feedback and reported total number of information bits of the HARQ-ACK information, the CSI report, and the SR information, in the above resource set, a resource set is reselected according to the range of the number of information bits, and according to the above DCI signaling The resource indication field in determines a new PUCCH in the newly selected new resource set.

It should be understood that the base station mentioned above reselects a resource set, which is referred to as a “first resource set” in the embodiments of the present application. The first resource set may be the original resource set or a newly selected other resource set. It is ensured that the total number of information bits of the HARQ-ACK information and the CSI report, or the total number of information bits of the HARQ-ACK information and the CSI report and the SR information is within a range of the number of bits of the first resource set.

For the above several possible situations, the new PUCCH newly determined by the base station and the terminal device may be a PUCCH long format with an OFDM symbol number of 4 to 14, such as the PUCCH format 1, PUCCH format 3, and PUCCH format 4 listed above. However, if there is another PUCCH resource with 4 to 14 symbols in the above-mentioned time slot, and the PUCCH and the newly determined PUCCH are used to carry HARQ-ACK and CSI information, or carry HARQ-ACK, CSI and SR PUCCH resources do not overlap in the time domain. According to the protocol, two long-format PUCCHs with 4 to 14 symbols cannot be sent in a slot. When there are two 4 to 14 symbol long PUCCHs in a slot at the same time, the terminal device and the base station cannot perform a definite transmission, in other words, the behaviors of the base station and the terminal device are uncertain. Therefore, a method for determining resources is needed, which can be used when the resources of the PUCCH carrying HARQ-ACK and CSI information overlap in the time domain, or the resources of the PUCCH carrying HARQ-ACK, CSI and SR information overlap in the time domain. , To re-determine a PUCCH resource, and to avoid two PUCCHs with 4 to 14 symbols in a time slot, thereby avoiding the uncertainty of transmission between a base station and a terminal device.

FIG. 4 is a schematic flowchart of an example method 400 for determining a transmission resource according to an embodiment of the present application. The method 400 may be applied to the terminal device 102 or the terminal device 103 of the wireless communication system 100 described above. FIG. 5 is a schematic diagram of an interaction between a terminal device and a base station in an embodiment of the present application, which will be described in detail below with reference to FIGS. 4 and 5.

As shown in FIG. 5, the method 500 includes the following content.

S501. In the first time slot, when the first uplink resource and the second uplink resource overlap in the time domain, the number of orthogonal frequency division multiplexing symbols included in the first resource set according to a preset rule is less than or equal to 2 The first resource is determined from the uplink resources of.

It should be understood that the first uplink resource is used to carry the first uplink information, and the second uplink resource is used to carry the second uplink information. The first uplink information and the second uplink information are hybrid automatic retransmission request response messages HARQ-ACK. Any one of the channel state information and CSI, any resource in the first resource set is a resource configured for an uplink control channel.

For example, the first uplink resource is the uplink control channel format PUCCH format 2, and the second uplink resource may also be the uplink control channel format PUCCH format 2.

Optionally, the types of the first uplink information and the second uplink information may be the same or different.

Specifically, the first uplink information may be HARQ-ACK, and the second uplink information may be CSI, and the situation in which the first uplink resource and the second uplink resource overlap in the time domain may be an uplink used to carry HARQ-ACK. The resources and uplink resources used to carry CSI all overlap or partially overlap in the time domain.

Alternatively, both the first uplink information and the second uplink information may be HARQ-ACKs, and the situation in which the first uplink resources and the second uplink resources overlap in the time domain may be uplink resources used to carry two types of HARQ-ACKs. Full or partial overlap in the time domain.

Or alternatively, both the first uplink information and the second uplink information may be CSI, then the situation in which the first uplink resource and the second uplink resource overlap in the time domain may be that the uplink resources used to carry the two types of CSI are in the time domain. All overlap or partially overlap.

Or alternatively, this also includes another possible situation, that is, the uplink resources used to carry HARQ-ACK, the uplink resources used to carry CSI, and the uplink resources used to carry SR all overlap or partially overlap in the time domain. It should be understood that in the case where all the uplink resources listed above overlap or partially overlap in the time domain, the technical solutions provided in this application can be used to determine the transmission resources between the base station and the terminal device. In other words, there may be more The scenario will cause the base station and the terminal device to determine the resources for uplink transmission. As long as the technical solution provided in the embodiment of this application is used to determine the transmission resources between the base station and the terminal device, all fall within the protection scope of this application.

It should also be understood that the “first resource set” in S501 may be an uplink resource set configured by the base station to the terminal device, for example, through high-level signaling. Specifically, after establishing a communication connection between the terminal device and the base station, the terminal device requests resources from the base station. The base station configures multiple uplink resource sets for the terminal device. Each uplink resource set includes multiple PUCCH resources with different numbers of symbols. Long format PUCCH resources with different numbers of symbols, such as PUCCH format 1, PUCCH format 3, and PUCCH format 4; or multiple short format PUCCHs with different numbers of symbols, such as PUCCH format 2.

Optionally, the first resource set is configured for at least one of the first uplink information and the second uplink information.

Specifically, for the base station, the first resource set may be determined according to at least one of the first uplink information and the second uplink information.

Accordingly, the terminal device may determine the first resource set according to at least one of the first uplink information and the second uplink information. For example, the first resource set is a resource set determined according to the first uplink information; or the first resource set is a resource set determined according to the second uplink information; or the first resource set is a first resource set according to the first uplink information And the resource set determined by the second uplink information.

Specifically, among the multiple resource sets configured by the base station for the terminal device, the base station needs to determine the first resource set according to the range of the number of information bits. Specifically, the base station may determine the first resource set according to the HARQ-ACK information to be fed back and reported; or re-determine the first resource set according to the HARQ-ACK information and the number of information bits reported by the CSI; or according to the HARQ-ACK information, the CSI The total number of information bits of the report and the SR information determines the first resource set.

Correspondingly, the terminal device receives the first indication information and the second indication information from the base station, the first indication information is used to indicate the first uplink resource, the second indication information is used to indicate the second uplink resource, and the first uplink resource and The second uplink resource overlaps in the time domain, the first uplink resource corresponds to the first uplink information, the second uplink resource corresponds to the second uplink information, and the first uplink information and the second uplink information are mixed automatically and repeatedly. Any of HARQ-ACK and channel state information CSI.

It should be understood that the first indication information may include one or more indication information, and the second indication information may include one or more indication information. It is often mentioned in the embodiments of the present application that the first uplink resource corresponds to the first uplink information, and “corresponding to” here can be understood as “bearer”, that is, the first uplink resource carries the first uplink information.

FIG. 6 is a schematic diagram of an example of a resource selection process provided by an embodiment of the present application. The process of determining a PUCCH by a base station and a terminal device is described in detail below with reference to FIG. 6. Assume that in one slot, there are three resources, namely a PUCCH carrying CSI report # 1, a PUCCH carrying CSI report # 2, and a PUCCH carrying HARQ-ACK information.

(1) The base station configures multiple uplink resource sets for the terminal device, such as resource set 1 and resource set 2 in FIG. 6, each uplink resource set includes multiple PUCCHs in different formats, and resource set 1 includes resource 1 in the figure. , Resource 3, resource 5, resource 8, etc., each resource has a different format. It is assumed that at this time, the base station determines resource set 1 according to the number of bits of the HARQ-ACK information to be transmitted, and informs the terminal device through DCI, and the terminal device determines resource 3 in resource set 1 according to the PUCCH resource indication field in the DCI.

(2) When the resources of HARQ-ACK and resources of CSI report # 1 overlap in the time domain, or the resources of HARQ-ACK and resources of CSI report # 1 overlap in the time domain, and carry the PUCCH of CSI report # 2 When the PUCCH is a long format, the base station needs to reselect the resource set 2 according to the HARQ-ACK information and the total number of bits in the CSI report. It should be understood that the resource set 2 is the first resource set defined in this application.

(3) In order to avoid two long-format PUCCHs in one slot at the same time, the terminal device needs to select a short-format resource in resource set 2, as shown in FIG. 6, resource 1 may be PUCCH format 2.

(4) After determining the first resource set, the base station and the terminal device determine the first resource from uplink resources whose number of orthogonal frequency division multiplexing symbols OFDM included in the first resource set is less than or equal to 2 according to a preset rule. For example, the base station and the terminal device may determine one PUCCH among a plurality of short-format PUCCHs with different numbers of symbols. As a first resource, the short-format PUCCH may be PUCCH format 2.

It should be understood that, in the embodiment of the present application, the number of time domain symbols occupied by the first resource is less than or equal to 2; and / or, the resource format of the first resource is the first format. The first format may be PUCCH format2.

For ease of description, a resource that contains the number of occupied time domain symbols less than or equal to 2 included in the first resource set is referred to as a second resource, and then the first resource set includes at least one second resource. In the following description, the second resource and the uplink resource with the number of symbols less than or equal to 2 both refer to the short format resource defined in this application, for example, PUCCH format2.

The following describes how to select the first resource from multiple short-format PUCCHs.

method one

The base station and the terminal device may determine the first resource according to the number of symbols of each uplink resource in the uplink resources whose number of symbols is less than or equal to two.

For example, the uplink resource with the largest number of symbols among the uplink resources whose number of symbols is less than or equal to 2 is determined as the first resource. For example, for PUCCH format 2, it is possible that the first PUCCH includes 1 symbol and the second PUCCH includes 2 symbols, and then the PUCCH with the largest number of symbols is selected as the first resource, that is, the PUCCH including 2 symbols is selected.

When the first resource set includes multiple uplink resources with the largest number of symbols and the number of the symbols is less than or equal to 2, the earliest or latest resource of the start symbol in the uplink resources with the largest number of symbols is determined as The first resource; or the resource with the smallest number of resource blocks RB in the uplink resources with the largest number of symbols is determined as the first resource.

It should be understood that each uplink resource will occupy a certain time domain location and frequency domain location. In the time domain, the number of symbols included in the PUCCH is different. For example, the PUCCH in the short format may include one or two symbols. In the frequency domain, the number of RBs included in the PUCCH is different. For example, the PUCCH format 2 may include 1 to 16 RBs. The above situation considers that the time domain and frequency domain space occupied by the PUCCH is the smallest. Selecting the resource with the least number of RBs can save transmission resources.

For example, when the second PUCCH includes 2 symbols and the third PUCCH also includes 2 symbols, it is selected according to the earliest or latest of the starting symbol of the PUCCH. Preferably, selecting the PUCCH with the latest start symbol can ensure that the terminal device has sufficient receiving time when receiving the message from the base station, and then performs feedback HARQ-ACK.

Optionally, when the first resource set includes a plurality of uplink resources with the same starting symbol and the number of the symbols is less than or equal to 2, or the first resource set includes a plurality of the resources with the least number of RBs and the number of the symbols is less than or equal to When the uplink resource is 2, the resource with the smallest resource index among the multiple uplink resources whose number of symbols is less than or equal to 2 is determined as the first resource.

Method Two

The base station and the terminal device may determine, as the first resource, an uplink resource whose number of symbols is less than or equal to 2 that is the same as the time domain length of the first uplink resource or the second uplink resource.

When the first resource set includes a plurality of uplink resources whose number of symbols is equal to or less than 2 in the time domain length of the first uplink resource or the second uplink resource, the plurality of uplink resources is equal to the first uplink resource or the second uplink resource. Or the resource with the earliest or latest start symbol in the uplink resource with the same number of symbols in the time domain of the second uplink resource as less than or equal to 2 is determined as the first resource; or the multiple resources are the same as the first uplink resource; Or, the resource with the smallest number of RBs in the uplink resources whose number of symbols is less than or equal to 2 in the same time domain length of the second uplink resource is determined as the first resource.

For example, when the first uplink resource is used to carry HARQ-ACK and the second uplink resource is used to carry information CSI, a short format resource with the same length as the resource carrying HARQ-ACK may be selected. When such a selection method still has multiple short-format resources in the first resource set, selection is performed according to the starting symbols of these short-format resources, for example, the earliest or latest starting symbol, and the resource with the latest starting symbol To optimize resources, it can be ensured that the terminal device has sufficient receiving time when receiving the message from the base station.

Method three

The base station and the terminal device may determine, as the first resource, an uplink resource whose number of symbols with the lowest coding rate in the first resource set is less than or equal to two.

When the first resource set includes a plurality of uplink resources with the lowest coding rate and the number of symbols is less than or equal to 2, the method further includes:

Determining, as the first resource, an uplink resource whose earliest or latest symbol number is the earliest or latest among the multiple resources with the lowest coding rate; and / or

The uplink resource with the number of symbols with the smallest number of resource blocks RB among the plurality of resources with the lowest coding rate and the number of symbols less than or equal to 2 is determined as the first resource.

Method four

The base station and the terminal device may determine the earliest or latest resource of the starting symbol among the uplink resources with the largest number of symbols as the first resource; and / or occupy the uplink resources with the largest number of symbols. The resource with the lowest number of resource blocks RB is determined as the first resource.

When the first resource set includes multiple uplink resources with the same starting symbol and the number of the symbols is less than or equal to 2, or the first resource set includes multiple uplink resources with the least number of RBs and the number of the symbols is less than or equal to 2. When the resource with the smallest resource index among the plurality of uplink resources whose number of symbols is less than or equal to 2 is determined as the first resource.

Method five

The base station and the terminal device may determine the resource with the smallest resource index among the multiple uplink resources whose number of symbols is less than or equal to 2 as the first resource.

It should be understood that the above-listed multiple rules for selecting uplink resources may be stipulated by a protocol, may also be configured for a base station and a terminal device through high-level signaling, or the base station may notify the terminal device through physical layer signaling. In the embodiment of the present application, the high-level signaling may be radio resource control (RRC) signaling, or may be MAC layer signaling.

It should be understood that the PUCCH in the first format in this application is also referred to as the PUCCH in the short format, and the PUCCH in the short format may refer to a PUCCH that includes one or two symbols, for example, PUCCH format 2 and PUCCH format 0; the second format The PUCCH is also called a long format PUCCH. The long format PUCCH may refer to a PUCCH that includes 4 to 14 symbols, for example, PUCCH format 1, format 3, and format 4.

S502. Transmit the first uplink information and the second uplink information through the first resource.

Specifically, the terminal device executes S420 to send the first uplink information and the second uplink information through the first resource. Correspondingly, the base station receives the first uplink information and the second uplink information through the first resource.

In the above transmission process of HARQ-ACK and CSI, or HARQ-ACK, CSI and RS, the base station and the terminal equipment can ensure the reliability of transmission through the determined uplink resources.

In addition, when the third uplink resource and the fourth uplink resource exist in the first time slot, the number of symbols included in the third uplink resource and the fourth uplink resource is greater than 4, and the third uplink resource and the fourth uplink resource Non-overlapping in the time domain, that is, it can be understood that in a time slot, there are two non-overlapping long-term PUCCHs in the time domain, including 4 to 14 symbols, in accordance with the requirements of the protocol. It is not possible to send two PUCCHs in long format including 4 to 14 symbols in the time slot, then the behavior of the UE and the base station will be uncertain at this time.

FIG. 7 is a schematic interaction diagram of still another resource determination method according to an embodiment of the present application. The method 700 may be applied to a terminal device or a base station of the wireless communication system 100 described above. The method 700 includes:

S701: Discard one of the third uplink resource and the fourth uplink resource according to a preset rule, where the number of symbols included in the third uplink resource and the fourth uplink resource is greater than four.

Optionally, the third uplink resource is used to carry third uplink information, the fourth uplink resource is used to carry fourth uplink information, and the third uplink information and the fourth uplink information are hybrid automatic repeat request response messages HARQ -ACK; or the third uplink information and the fourth uplink information are channel state information CSI; or the third uplink information and the fourth uplink information are at least two of HARQ-ACK, channel state information CSI, and scheduling request SR information.

Specifically, for example, in FIG. 2, it is assumed that in a time slot, there are three resources, namely a PUCCH carrying CSI report # 1, a PUCCH carrying CSI report # 2, and a PUCCH carrying HARQ-ACK information, and carrying CSI The PUCCH of report # 2 is a long format resource, such as PUCCH format 4; or in FIG. 3, there are four resources, namely the PUCCH carrying CSI report # 1, the PUCCH carrying CSI report # 2, and the PUCCH carrying SR With a PUCCH carrying HARQ-ACK information, and a PUCCH carrying CSI report # 2 is a long format resource, such as PUCCH format 4. If the terminal device determines a new transmission resource based on the total number of bits of HARQ-ACK and CSI or the total number of bits of HARQ-ACK, CSI, and SR is a long-format PUCCH, such as PUCCH format 1, PUCCH format 3, or PUCCH When any one of Format 4 and the newly determined PUCCH in the long format and the PUCCH used to carry the CSI report # 2 do not overlap in the time domain, then there are two PUCCHs in the long format in this one slot.

In order to ensure the reliability of the transmission, the terminal device may discard one of the long-format PUCCHs according to a certain rule, and only one long-format PUCCH is reserved in the time slot.

In a possible implementation manner, the terminal device may discard the uplink resources carrying the uplink information of the first priority according to a preset priority order, and reserve the uplink resources carrying the uplink information of the second priority, where the second priority is The priority is higher than the first priority.

For example, if the priority of HARQ-ACK is higher than the priority of CSI, the uplink resources used to carry CSI can be discarded.

Alternatively, if the priority of the HARQ-ACK is lower than the priority of the CSI, the uplink resources used to carry the HARQ-ACK may be discarded.

Or, if the priority of the information of the CSI report # 2 is higher than the priority of the CSI report # 1, the long-format PUCCH used to carry HARQ-ACK and CSI report # 1 is discarded.

Or, if the priority of the information of CSI report # 2 is lower than the priority of HARQ-ACK and CSI report # 1, the long-format PUCCH used to carry CSI report # 2 is discarded.

When resources carrying low-priority uplink information are discarded according to the priority of the uplink information, there is only one PUCCH in a long format in the one time slot.

S702. Transmit the third uplink resource and another resource that has not been dropped from the fourth uplink resource.

The terminal device sends high-priority uplink information on the PUCCH that has not been discarded. Accordingly, the base station receives the PUCCH and obtains the high-priority uplink information.

Through the above technical solution, during the uplink transmission between the terminal device and the base station, the problem of transmission uncertainty caused by the occurrence of two long-format PUCCH resources in one time slot can be avoided.

FIG. 8 is a schematic diagram of another example of a resource selection process according to an embodiment of the present application. In the process of sending uplink information, in the process of sending uplink information, when the resources of the PUCCH carrying HARQ-ACK and CSI information overlap in the time domain in the same time slot, or the PUCCH carrying HARQ-ACK, CSI and SR information The resources overlap in the time domain, and the new transmission resource determined according to the total number of bits of HARQ-ACK and CSI information, or the total number of bits of information of HARQ-ACK, CSI, and SR is a long format PUCCH. In addition, there is another PUCCH in the long format in this time slot, and the resource selection process shown in FIG. 8 can be performed.

Specifically, in one time slot, PUCCH format 2 carrying HARQ-ACK and PUCCH format 2 of CSI report # 1 information overlap in the time domain, and a new one is determined according to the total number of bits of HARQ-ACK and CSI report # 1 information. The new PUCCH resource is a PUCCH in format 3. If the PUCCH in format 3 and the PUCCH in format 4 used to carry CSI report # 2 do not overlap in the time domain, the priority of the uplink information carried is Two long format resources are discarded. In Figure 8, the priority of CSI report # 1 is higher than the priority of CSI report # 2. Therefore, the PUCCH used to carry format 4 of CSI report # 2 is discarded, thereby ensuring that there is only one long format in this time slot. PUCCH improves transmission reliability.
