Description

Technical Field

[0001] The embodiments of the present application relate to the field of communications, and in particular, to a communication method and apparatus. Background Art

[0002] The duplex modes in a mobile communication system include full duplex and half duplex. If the transmission and reception of a communication device can be performed simultaneously, it is full duplex (FD). If the transmission and reception of a communication device cannot be performed simultaneously, it is half duplex (HD). Among them, the communication device includes a network device and / or a terminal device.

[0003] In FD, the same time-frequency resource can be used for uplink transmission and downlink transmission simultaneously. Therefore, compared with SBFD, there are more uplink resources and downlink resources, which can greatly improve the uplink coverage performance and effectively reduce the latency. However, since the frequency-domain resources in the uplink resources and the frequency-domain resources in the downlink resources are not isolated in a time slot, cross-link interference (CLI) is likely to occur between network devices and between terminal devices.

[0004] In addition, the new radio (NR) system has high requirements for the reliability of the control channel. However, the severe CLI in FD will greatly reduce the reliability of the control channel. Therefore, how to solve the impact of CLI on the reliability of the control channel is an urgent problem to be solved. Summary of the Invention

[0005] The communication method and apparatus provided by the embodiments of the present application can reduce the impact of cross-link interference CLI on the reliability of the control channel.

[0006] In a first aspect, a communication method is provided. This method can be executed by a terminal device, or by a component of the terminal device, such as a processor, a chip, or a chip system of the terminal device, or can also be implemented by a logic module or software that can implement all or part of the functions of the terminal device. The method includes: receiving first information, where the first information indicates a first time-frequency resource, where the first time-frequency resource includes a time-frequency resource for carrying a reference signal of a physical uplink control channel (PUCCH), or the first time-frequency resource includes the time-frequency resource of the PUCCH; receiving second information, where the second information indicates receiving a downlink signal on a second time-frequency resource, where the second time-frequency resource overlaps with the first time-frequency resource; receiving a downlink signal on a third time-frequency resource, where the third time-frequency resource is the time-frequency resource in the second time-frequency resource except the first time-frequency resource.

[0007] Based on this solution, when the first information indicates the first time-frequency resource, if the second time-frequency resource indicated by the second information for transmitting the downlink signal overlaps with the first time-frequency resource, the network device transmits the indication information of the downlink signal on the third time-frequency resource in the second time-frequency resource except the first time-frequency resource. That is to say, the first time-frequency resource is not used for transmitting the downlink signal; in addition, since the first time-frequency resource includes the time-frequency resource for carrying the reference signal of the PUCCH, or the first time-frequency resource includes the time-frequency resource of the PUCCH, the terminal device can send the PUCCH or the reference signal of the PUCCH on the first time-frequency resource, which can avoid the downlink signal causing CLI to the PUCCH or the reference signal of the PUCCH, thereby improving the reliability of the uplink signal.

[0008] In a second aspect, a communication method is provided. This method can be executed by the network device, or by components of the network device, such as the processor, chip, or chip system of the network device, etc., and can also be implemented by a logic module or software that can implement all or part of the functions of the network device. The method includes: sending first information, where the first information indicates the first time-frequency resource, and the first time-frequency resource includes the time-frequency resource for carrying the reference signal of the PUCCH, or the first time-frequency resource includes the time-frequency resource of the PUCCH; sending second information, where the second information indicates receiving the downlink signal on the second time-frequency resource, and the second time-frequency resource overlaps with the first time-frequency resource; transmitting the downlink signal on the third time-frequency resource, where the third time-frequency resource is the time-frequency resource in the second time-frequency resource except the first time-frequency resource.

[0009] Based on this solution, when the first information indicates the first time-frequency resource, if the second time-frequency resource indicated by the second information for transmitting the downlink signal overlaps with the first time-frequency resource, the network device transmits the downlink signal on the third time-frequency resource in the second time-frequency resource except the first time-frequency resource. That is to say, the first time-frequency resource is not used for transmitting the downlink signal; in addition, since the first time-frequency resource includes the time-frequency resource for carrying the reference signal of the PUCCH, or the first time-frequency resource includes the time-frequency resource of the PUCCH, the terminal device can send the PUCCH or the reference signal of the PUCCH on the first time-frequency resource, which can avoid the downlink signal causing CLI to the PUCCH or the reference signal of the PUCCH, thereby improving the reliability of the uplink signal.

The implementation manners of the present application described below do not constitute a limitation to the protection scope of the present application.

[0087] To facilitate the understanding of the technical solutions of the embodiments of the present application, a brief introduction to the related technologies of the present application is given as follows.

[0088] 1. Time slot:

[0089] In New Radio (NR), for the normal cyclic prefix (CP), one time slot contains 14 orthogonal frequency division multiplexing (OFDM) symbols (hereinafter referred to as symbols). For the extended CP, one time slot contains 12 symbols. For ease of description, in the embodiments of this application, if not otherwise specified, one time slot contains 14 symbols. Exemplarily, in one time slot, the 14 symbols are numbered in ascending order, the smallest number is 0, and the largest number is 13. In fact, in one time slot, there may be other implementation forms for the number of symbols, which are not limited in this application.

[0090] One time slot can be an uplink slot (U), a downlink slot (D), or a special slot (S). Among them, the uplink slot is configured to be only used for uplink (UL) transmission, and all symbols in the uplink slot are uplink symbols, that is, the uplink symbols are configured to be only used for uplink transmission; the downlink slot is configured to be only used for downlink (DL) transmission, and all symbols in the downlink slot are downlink symbols, that is, the downlink symbols are configured to be only used for downlink transmission; the special slot can be configured to be used for uplink transmission or configured to be used for downlink transmission, but cannot be used for both uplink and downlink transmission at the same time. The special slot can be used as a transition point between uplink and downlink. The symbols in the special slot can include a part of uplink symbols, a part of downlink symbols, and guard symbols. The guard symbols are located between the uplink symbols and the downlink symbols in the special slot, and no data can be transmitted on the guard symbols.

[0091] It should be understood that in uplink transmission, the terminal device sends uplink data, and the radio access network device receives the uplink data. In downlink transmission, the radio access network device sends downlink data, and the terminal device receives the downlink data.

[0092] 2. Duplex Mode:

[0093] At present, the duplex modes in mobile communication systems include full duplex and half duplex. If the transmission and reception of a communication device can be carried out simultaneously, it is full duplex (FD). If the transmission and reception of a communication device cannot be carried out simultaneously, it is half duplex (HD). Among them, the communication device includes a network device and / or a terminal device. For example, both the network device and the terminal device are full duplex, or both the network device and the terminal device are half duplex, or the network device is full duplex and the terminal device is half duplex, or the network device is half duplex and the terminal device is full duplex.

[0094] (1), Time Division Duplexing (TDD):

[0095] TDD is widely used in the deployment of the new radio (NR) communication system in the fifth generation (5G) of mobile communication systems. In TDD, the time domain resources are divided into uplink resources and downlink resources. Among them, uplink transmission can be carried out on the uplink resources, and downlink transmission can be carried out on the downlink resources. In TDD, the frequency ranges of UL and DL are the same, so uplink transmission and downlink transmission cannot be carried out simultaneously. That is, TDD is for half duplex. For example, both the terminal device and the network device can be half duplex.

[0096] Exemplarily, taking a time period with a TDD frame ratio of 4:1 and this time period including 5 time slots (such as time slot #0 to time slot #5) as an example, this time period includes the content shown in Table 1 below:

[0097] Table 1

[0098] Time slot Time slot #0 Time slot #1 Time slot #2 Time slot #3 Time slot #4 Time slot type D D D S U

[0099] As can be seen from Table 1, in TDD, one time slot can only be used for downlink transmission or only for uplink transmission, and compared with the downlink resources in one time period, the uplink resources are less, resulting in a reduction in the uplink coverage of TDD and an increase in latency.

[0100] (2), Subband Full Duplex (SBFD):

[0101] In SBFD, the frequency ranges of UL and DL are the same, and in one time slot, the frequency domain resources in the uplink resources and the frequency domain resources in the downlink resources are different, so uplink transmission and downlink transmission can be carried out simultaneously. Therefore, SBFD is full duplex. For example, the network device can be full duplex, and the terminal device can be half duplex or full duplex.

[0102] Among them, in SBFD, the frequency band on the downlink symbols in the downlink time slots (or special time slots) is divided into one or more uplink sub-bands and one or more downlink sub-bands, and the uplink sub-bands in the uplink symbols are allowed to be used for uplink transmission.

[0103] Exemplarily, taking a time period with a TDD frame ratio of 4:1, and this time period includes 5 time slots (such as time slot #0 to time slot #5) as an example, this time period includes the content shown in Table 2 (Table 2A or Table 2B) as follows:

[0104] Table 2A

[0105]

[0106] Table 2B

[0107]

[0108] As can be seen from Table 2, the frequency band on the downlink symbols in the downlink time slots (or special time slots) (at least one of the time slots #0 to #3 in Table 2) is divided into one uplink sub-band and two downlink sub-bands. Among them, uplink transmission can be performed on this uplink sub-band. Compared with TDD, the uplink coverage performance can be improved. That is, this uplink sub-band can also be used to feedback hybrid automatic repeat request-acknowledgement (HARQ-ACK), thereby reducing the delay.

[0109] (3), FD:

[0110] In FD, the same time-frequency resources can be used for uplink transmission and downlink transmission simultaneously. Exemplarily, taking a time period with a TDD frame ratio of 4:1, and this time period includes 5 time slots (such as time slot #0 to time slot #5) as an example, this time period includes the content shown in Table 3 as follows:

[0111] Table 3

[0112]

[0113] As can be seen from Table 3, the symbols in each time slot within this time period can be used for both uplink transmission and downlink transmission, and can be used for uplink transmission and downlink transmission simultaneously. Compared with SBFD, there are more uplink resources and downlink resources, thereby being able to greatly improve the uplink coverage performance and effectively reduce the delay.

[0114] In FD, since the frequency-domain resources in the uplink resources and the frequency-domain resources in the downlink resources are not isolated in a time slot, cross-link interference (CLI) will occur between network devices and between terminal devices. Among them, CLI refers to the interference between communication links with opposite directions, that is, the interference of uplink transmission on downlink transmission, or the interference of downlink transmission on uplink transmission.

[0115] See Figure 1 , which is a schematic diagram of a network architecture of an FD applied in an embodiment of this application.

[0116] As Figure 1 shown, the terminal devices served by network device #1 are terminal device #1 and terminal device #2, and the terminal devices served by network device #2 are terminal device #3 and terminal device #4. Among them, downlink transmission is performed between network device #1 and terminal device #1, and uplink transmission is performed between network device #1 and terminal device #2; downlink transmission is performed between network device #2 and terminal device #3, and uplink transmission is performed between network device #2 and terminal device #4. Therefore, CLI will occur between network device #1 and network device #2 and between terminal devices. Taking the interference of uplink transmission on downlink transmission as an example, the CLI generated between terminal devices may include: the interference of the uplink transmission between terminal device #2 and network device #1 on the downlink transmission between terminal device #1 and network device #1, the interference of the uplink transmission between terminal device #2 and network device #1 on the downlink transmission between terminal device #3 and network device #2, and the interference of the uplink transmission between terminal device #4 and network device #2 on the downlink transmission between terminal device #3 and network device #2.

[0117] In the NR system, there are relatively high requirements for the reliability of the control channel. Among them, the control channel includes: physical uplink control channel (PUCCH) and physical downlink control channel (PDCCH). However, severe CLI in FD will greatly reduce the reliability of the control channel. Therefore, how to solve the impact of CLI on the reliability of the control channel is an urgent problem to be solved. Hereinafter, taking the solution to the impact of CLI on the reliability of PUCCH as an example for introduction.

[0118] An easily conceivable method is to adopt a rate matching scheme for the physical downlink shared channel (PDSCH) ((and / or PDCCH; for the sake of convenient description, PDSCH will be taken as an example for introduction below)). On the time-frequency resources where the demodulation reference signal (DMRS) of the PUCCH is located, rate matching is performed on the PDSCH, that is, the PDSCH is not transmitted or received on the time-frequency resources where the DRMS of the PUCCH is located, so as to avoid the interference of the PDSCH on the DRMS of the PUCCH, thereby improving the performance of the channel estimation of the PDCCH and enhancing the reliability of the PUCCH. The existing protocol supports the network device to configure a rate matching pattern for the terminal device, or, it can also be called reserved resources. The rate matching pattern is located in the high-layer signaling RateMatchPattern. The rate matching pattern is a set of time-frequency resources on which the network device cannot transmit the PDSCH and the terminal device cannot receive the PDSCH.

[0119] Specifically, the rate matching of the PDSCH can be implemented based on the following two methods:

[0120] Method 1: Rate matching based on the resource block (RB) granularity.

[0121] Optionally, the network device can indicate the time-frequency resources through high-layer signaling to obtain the rate matching pattern of the PDSCH. The high-layer signaling includes the signaling symbolsInResourceBlock, the signaling periodicityAndPattern, and the signaling resourceBlocks.

[0122] Among them, the signaling symbolsInResourceBlock is used to indicate the number of time slots in a time unit and the time-domain resources in a time unit. The signaling periodicityAndPattern is used to indicate the repetition period of the rate matching pattern of the PDSCH and the starting position of the time-domain resources within this repetition period. The signaling resourceBlocks is used to indicate the frequency-domain resources. Among them, the repetition period in the embodiments of this application refers to the number of time units in a repetition period.

[0123] Exemplarily, the network device can configure up to 8 rate matching patterns for the terminal device. Among them, the 8 rate matching patterns include 4 rate matching patterns at the bandwidth part (BWP) level and 4 rate matching patterns at the cell level.

[0124] Optionally, a time unit may include one or two time slots; when a time unit includes one time slot, the signaling symbolsInResourceBlock may indicate the time-domain resources within a time unit through a bitmap with a length of 14. When a time unit includes two time slots, the signaling symbolsInResourceBlock may indicate the time-domain resources within a time unit through a bitmap with a length of 28. Among them, one bit in the bitmap corresponds to one symbol within the time unit. For example, a value of 1 in the bitmap may indicate that the symbol corresponding to the bitmap is the time-domain resource in the rate matching pattern of PDSCH.

[0125] Optionally, the signaling periodicityAndPattern may indicate the repetition period through a bitmap, where the length of the bitmap is equal to the number of time units within one repetition period. One bit in the bitmap corresponds to one time unit. For example, a value of 1 in the bitmap may indicate that the time unit corresponding to the bitmap is the time-domain resource in the rate matching pattern of PDSCH.

[0126] Exemplarily, the value of the number of time units within one repetition period may be any one of 2, 4, 5, 8, 10, 20, 40.

[0127] Optionally, the signaling resourceBlocks may indicate the frequency-domain resources within one symbol through a bitmap. Among them, the frequency-domain resources within each symbol are the same, that is, the frequency-domain resources on different time-domain resources are the same. One bit in the bitmap corresponds to one RB. For example, a value of 1 in the bitmap may indicate that the symbol corresponding to the bitmap is the frequency-domain resource in the rate matching pattern of PDSCH.

[0128] See Figure 2 , which is a schematic diagram of the time-frequency resources of a rate matching pattern of PDSCH provided by an embodiment of this application.

[0129] In Figure 2 , one repetition period includes 4 time units (i.e., time unit #1 to time unit #4), and time unit #1 and time unit #2 are the time-domain resources of the rate matching pattern of PDSCH; a time unit may include one time slot, or may also include two time slots, where Figure 2 Taking the case where a time unit includes two time slots as an example, the RBs within the two time slots are as Figure 2 shown, where the RBs corresponding to the shaded part are the time-frequency resources of the rate matching pattern of PDSCH.

[0130] As an example, the rate matching pattern of PDSCH may be semi-statically configured.

[0131] Exemplarily, in this example, when the terminal device receives the rate matching pattern of the PDSCH, it takes effect immediately.

[0132] As another example, the rate matching pattern of the PDSCH can be dynamically configured.

[0133] Optionally, in this example, the network device configures two sets of rate matching patterns for the terminal device, where each set of rate matching patterns includes at least one rate matching pattern. Exemplarily, the network device can indicate the two sets of rate matching patterns through signaling rateMatchPatternGroup1 and signaling rateMatchPatternGroup2.

[0134] Optionally, the network device can trigger one set of rate matching patterns among the two sets of rate matching patterns through downlink control information (DCI). That is, this set of rate matching patterns is the rate matching pattern of the PDSCH.

[0135] Exemplarily, triggering one set of rate matching patterns among the two sets of rate matching patterns can be understood as: triggering all rate matching patterns in this set of rate matching patterns.

[0136] Exemplarily, the network device can indicate triggering one set of rate matching patterns among the two sets of rate matching patterns through 1 bit. For example, when the value of this 1 bit is 1, it indicates triggering the first set of rate matching patterns among the two sets of rate matching patterns. Correspondingly, when the value of this 1 bit is 0, it indicates triggering the second set of rate matching patterns among the two sets of rate matching patterns; or, when the value of this 1 bit is 0, it indicates triggering the first set of rate matching patterns among the two sets of rate matching patterns, and correspondingly, when the value of this 1 bit is 1, it indicates triggering the second set of rate matching patterns among the two sets of rate matching patterns.

[0137] Method 2: Rate matching based on the granularity of resource elements (RE).

[0138] Exemplarily, in Method 2, the rate matching of the PDSCH is implemented through the channel state information reference signal (CSI-RS).

[0139] Exemplarily, CSI-RS includes non-zero power (NZP) CSI-RS and zero power (ZP) CSI-RS. Among them, the time-frequency resources of NZP CSI-RS and ZP CSI-RS are the same.

[0140] Optionally, the network device may indicate the time-frequency resources of the CSI-RS through high-layer signaling, so as to obtain the rate matching pattern of the PDSCH. The high-layer signaling includes the signaling CSI-RS-ResourceMapping and the signaling NZP-CSI-RS-Resource.

[0141] Exemplarily, the signaling CSI-RS-ResourceMapping is used to indicate the frequency-domain density of the CSI-RS, the number of ports of the CSI-RS, the code division multiplexing (CDM) type corresponding to the ports of the CSI-RS, and the time-frequency position corresponding to the CSI-RS. The signaling NZP-CSI-RS-Resource is used to indicate the power control parameters.

[0142] Optionally, the density field in the signaling CSI-RS-ResourceMapping is used to indicate the frequency-domain density ρ of the CSI-RS.

[0143] Exemplarily, the value of the density field may be at least one of 1, 0.5, or 3. Among them, when the value of the density field is 1, it means that one RE for carrying the CSI-RS corresponds to one RB, and at this time, the frequency-domain density of the CSI-RS can be called 1. When the value of the density field is 0.5, it means that one RE for carrying the CSI-RS corresponds to every other RB, and at this time, the frequency-domain density of the CSI-RS can be called 0.5; at this time, the network device may also indicate the index number of the RB for carrying the CSI-RS. When the value of the density field is 3, it means that three REs for carrying the CSI-RS correspond to one RB, and at this time, the frequency-domain density of the CSI-RS can be called 3.

[0144] Optionally, the nrofPorts field in the signaling CSI-RS-ResourceMapping is used to indicate the number of ports X of the CSI-RS.

[0145] Optionally, the cdm-Type field in the signaling CSI-RS-ResourceMapping is used to indicate the CDM type corresponding to the ports of the CSI-RS.

[0146] Exemplarily, the CDM type includes time-domain mask elements and frequency-domain mask elements. Among them, the time-domain mask element can also be referred to as a time-division orthogonal cover code (TD-OCC), and the frequency-domain mask element can also be referred to as a frequency-division orthogonal cover code (FD-OCC).

[0147] Optionally, the firstOFDMSymbolInTimeDomain field in the signaling CSI-RS-ResourceMapping is used to indicate the time-domain position l of the CSI-RS i , further, the firstOFDMSymbolInTimeDomain2 in the signaling CSI-RS-ResourceMapping can also be used to indicate the time-domain position l of the CSI-RS i+1 . l i ∈ {0, 1,..., 13}, l i+1 ∈ {2, 3,..., 12}. The frequencyDomainAllocation field in the signaling CSI-RS-ResourceMapping is used to indicate the frequency-domain position k of the CSI-RS i .

[0148] Exemplarily, when the cdm-Type field indicates noCDM, the frequency-domain density of the CSI-RS is in terms of RE granularity, that is, the frequency-domain density of the CSI-RS at this time refers to the number of REs used to carry the CSI-RS within an RB. When the cdm-Type field indicates the existence of a CDM group (such as fd-CDM2, cdm4-FD2-TD2, cdm8-FD2-TD4, etc.), the frequency-domain density of the CSI-RS is in terms of CDM group granularity, that is, the frequency-domain density of the CSI-RS at this time refers to the number corresponding to each CDM group used to carry the CSI-RS within an RB. Among them, the number of each CDM group used to carry the CSI-RS within an RB is the same. And one CDM group occupies two consecutive REs in the frequency domain.

[0149] Exemplarily, when the number of ports of the CSI-RS is 1, the cdm-Type field indicates noCDM. At this time, the time-frequency resources of the CSI-RS within an RB (that is, the REs used to carry the CSI-RS) can include three cases: (1), there are 3 REs used to carry the CSI-RS within an RB, such as Figure 3As shown in (a) therein, the indexes of the 3 REs are respectively (k0, l0), (k0 + 4, l0), (k0 + 8, l0); (2), one RB includes 1 RE for carrying CSI-RS, as Figure 3 shown in (b) therein, the index of the 1 RE is (k0, l0); (3), every two RBs include one RE for carrying CSI-RS, and the RB where the RE for carrying CSI-RS is located is as Figure 3 shown in (b) therein.

[0150] When the number of ports of CSI-RS is 2 or 4, the cdm-Type field indicates fd-CDM2; when the number of ports of CSI-RS is 2, one RB includes 1 CDM group for carrying CSI-RS, as Figure 4 shown, the index of the 1 CDM group is (k0, l0). When the number of ports of CSI-RS is 4, one RB includes 2 CDM groups for carrying CSI-RS, as Figure 5 shown in (a) therein, the indexes of the 2 CDM groups are respectively (k0, l0), (k0 + 2, l0); or, as Figure 5 shown in (b) therein, the indexes of the 2 CDM groups are respectively (k0, l0), (k0, l0 + 1).

[0151] When the number of ports of CSI-RS is any one of 8, 12 or 16, the cdm-Type field indicates fd-CDM2 or cdm4-FD2-TD2; combining the above Table 3, it can be known that when the cdm-Type field indicates fd-CDM2, if the number of ports of CSI-RS is 8, then one RB includes 4 CDM groups for carrying CSI-RS, as Figure 6 shown in (a) therein, the indexes of the 4 CDM groups are respectively (k0, l0), (k1, l0), (k2, l0), (k3, l0); or, as Figure 6 shown in (b) therein, the indexes of the 4 CDM groups are respectively (k0, l0), (k1, l0), (k2, l0), (k3, l0 + 1). If the number of ports of CSI-RS is 12, then one RB includes 6 CDM groups for carrying CSI-RS, as Figure 7 shown in (a) therein, the indexes of the 6 CDM groups are respectively (k0, l0), (k1, l0), (k2, l0), (k3, l0), (k4, l0), (k5, l0). If the number of ports of CSI-RS is 16, then one RB includes 8 CDM groups for carrying CSI-RS, as Figure 8As shown in (a) thereof, the indexes of the 8 CDM groups are respectively (k0, l0), (k1, l0), (k2, l0), (k3, l0), (k0, l0 + 1), (k1, l0 + 1), (k2, l0 + 1), (k3, l0 + 1).

[0152] When the cdm-Type field indicates cdm4-FD2-TD2, if the number of ports of CSI-RS is 8, then there are 2 CDM groups for carrying CSI-RS in one RB, as Figure 6 shown in (c) thereof, the indexes of the 2 CDM groups are respectively (k0, l0), (k1, l0). If the number of ports of CSI-RS is 12, then there are 3 CDM groups for carrying CSI-RS in one RB, as Figure 7 shown in (b) thereof, the indexes of the 3 CDM groups are respectively (k0, l0), (k1, l0), (k2, l0). If the number of ports of CSI-RS is 16, then there are 4 CDM groups for carrying CSI-RS in one RB, as Figure 8 shown in (b) thereof, the indexes of the 4 CDM groups are respectively (k0, l0), (k1, l0), (k2, l0), (k3, l0).

[0153] When the number of ports of CSI-RS is 24 or 32, the cdm-Type field indicates any one of fd-CDM2, cdm4-FD2-TD2 or cdm8-FD2-TD4. When the cdm-Type field indicates fd-CDM2, if the number of ports of CSI-RS is 24, then there are 12 CDM groups for carrying CSI-RS in one RB, as Figure 9 shown in (a) thereof, the indexes of the 12 CDM groups are respectively (k0, l0), (k1, l0), (k2, l0), (k0, l0 + 1), (k1, l0 + 1), (k2, l0 + 1), (k0, l1), (k1, l1), (k2, l1), (k0, l1 + 1), (k1, l1 + 1), (k2, l1 + 1). If the number of ports of CSI-RS is 32, then there are 16 CDM groups for carrying CSI-RS in one RB, as Figure 10 shown in (a) thereof, the indexes of the 16 CDM groups are respectively (k0, l0), (k1, l0), (k2, l0), (k3, l0), (k0, l0 + 1), (k1, l0 + 1), (k2, l0 + 1), (k3, l 0+1 ),(k0, l1), (k1, l1), (k2, l1), (k3, l1), (k0, l1 + 1), (k1, l1 + 1), (k2, l1 + 1), (k3, l1 + 1).

[0154] When the cdm-Type field indicates cdm8-FD2-TD4, if the number of ports of CSI-RS is 24, then there are 6 CDM groups for carrying CSI-RS in one RB. As shown in (b) of Figure 9 , the indexes of these 6 CDM groups are (k0, l0), (k1, l0), (k2, l0), (k0, l1), (k1, l1), (k2, l1) respectively. If the number of ports of CSI-RS is 32, then there are 8 CDM groups for carrying CSI-RS in one RB. As shown in (b) of Figure 10 , the indexes of these 8 CDM groups are (k0, l0), (k1, l0), (k2, l0), (k3, l0), (k0, l1), (k1, l1), (k2, l1), (k3, l1) respectively.

[0155] When the cdm-Type field indicates cdm4-FD2-TD2, if the number of ports of CSI-RS is 24, then there are 3 CDM groups for carrying CSI-RS in one RB. As shown in (c) of Figure 9 , the indexes of these 3 CDM groups are (k0, l0), (k1, l0), (k2, l0) respectively. If the number of ports of CSI-RS is 32, then there are 4 CDM groups for carrying CSI-RS in one RB. As shown in (c) of Figure 10 , the indexes of these 4 CDM groups are (k0, l0), (k1, l0), (k2, l0), (k3, l0) respectively.

[0156] However, based on the PDSCH rate matching in the above two ways, it may not be possible to match the time-frequency resources of the flexible PUCCH, resulting in some resources in the time-frequency resources of the PUCCH being able to transmit the time-frequency resources of the PDSCH, causing interference to the PUCCH and thus affecting the reliability of the PUCCH.

[0157] Specifically, there may be the following problems in the PDSCH rate matching in Method 1:

[0158] (1) The repetition period in the PDSCH rate matching in Method 1 cannot support the repetition period of the semi-statically configured PUCCH. Among them, the value of the number of time slots in the repetition period of the semi-statically configured PUCCH can be any one of 4, 5, 8, 10, 16, 20, 40, 80, 160, 320.

[0159] Since the value of the repetition period (i.e., the number of time units included in one repetition period) in PDSCH rate matching in Mode 1 can be any one of 2, 4, 5, 8, 10, 20, 40, and one time unit includes one or two time slots, therefore, the value of the number of time slots in PDSCH rate matching in Mode 1 can be 2, 4, 5, 8, 10, 16, 20, 40, 80. Thus, the repetition period in PDSCH rate matching in Mode 1 cannot match the case where the repetition period of semi-statically configured PUCCH is 160 or 320 time slots.

[0160] (2) PDSCH rate matching in Mode 1 cannot support the case of PUCCH frequency hopping. Since in PDSCH rate matching in Mode 1, the frequency domain resources on different time domain resources are the same. However, in the case of PUCCH frequency hopping, the frequency domain resources on different time domain resources are different. Thus, in order to match the case of PUCCH frequency hopping, a large amount of resources need to be consumed and the complexity of the scheme is increased.

[0161] (3) PDSCH rate matching in Mode 1 cannot support the configuration of time-frequency resources with RE granularity in the time-frequency resources of PUCCH. Since PDSCH rate matching in Mode 1 is based on RB granularity, and there is a configuration scheme with RE granularity in the time-frequency resources of PUCCH. Thus, in order to match the time-frequency resources of PUCCH with RE granularity, a large amount of resources need to be consumed and the complexity of the scheme is increased.

[0162] (4) PDSCH rate matching in Mode 1 only supports 8 PDSCH rate matching patterns in Mode 1 and cannot support the flexible configuration of the time-frequency resources of PUCCH.

[0163] There may be the following problems in PDSCH rate matching in Mode 1:

[0164] (1) PDSCH rate matching in Mode 2 cannot support the configuration of time-frequency resources in PUCCH format 2. Since in the time-frequency resource configuration of PUCCH format 2, one RB includes 4 REs for carrying reference signals (RS), and there are two REs between adjacent two REs. Combining with the relevant descriptions above Figures 3 to 10 there is no pattern that can match the time-frequency resources in PUCCH format 2. Thus, in order to match the time-frequency resources in PUCCH format 2, a large amount of resources need to be consumed and the complexity of the scheme is increased.

[0165] (2) The PDSCH rate matching cannot support the case of PUCCH hopping. In the PDSCH rate matching in Method 2, the frequency domain resources on different time domain resources are the same. However, in the case of PUCCH hopping, the frequency domain resources on different time domain resources are different. Therefore, in order to match the case of PUCCH hopping, a large amount of resources need to be consumed, and the complexity of the solution is increased.

[0166] In view of this, the embodiments of the present application provide a communication method and apparatus. When the first information indicates the first time-frequency resource, if the second time-frequency resource for transmitting the downlink signal indicated by the second information overlaps with the first time-frequency resource, the network device transmits the downlink signal on the third time-frequency resource other than the first time-frequency resource in the second time-frequency resource. That is to say, the first time-frequency resource is not used to transmit the downlink signal; in addition, since the first time-frequency resource includes the time-frequency resource for carrying the reference signal of the PUCCH, or the first time-frequency resource includes the time-frequency resource of the PUCCH, the terminal device can send the PUCCH or the reference signal of the PUCCH on the first time-frequency resource, which can avoid the CLI caused by the downlink signal to the PUCCH or the reference signal of the PUCCH, thereby improving the reliability of the uplink signal.

[0167] The embodiments of the present application can be applied to the WLAN scenario, and can be applied to the IEEE 802.11 system standard, such as the 802.11a / b / g standard, the 802.11n standard, the 802.11ac standard, the 802.11ax standard, or its next generation, such as the 802.11be standard or a more next-generation standard. Or, the embodiments of the present application can also be applied to wireless local area network systems such as the Internet of Things (IoT) network or the Vehicle to X (V2X) network.

[0172] It should be noted that the WLAN communication system described in the embodiments of the present application is for more clearly explaining the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those of ordinary skill in the art can know that with the evolution of the network architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0173] The following Figure 11 Taking the interaction between an AP and a terminal device in the shown WLAN communication system as an example, the communication method provided by the embodiments of the present application will be described.

[0174] It should be noted that in the following embodiments of the present application, the message names, parameter names, or information names between various devices are only examples. In other embodiments, they can also be other names, and the method provided by the present application does not make specific limitations on this.

[0175] It can be understood that in the embodiments of the present application, the execution subject can execute some or all of the steps in the embodiments of the present application. These steps or operations are only examples. The embodiments of the present application can also execute other operations or various deformations of the operations. In addition, the various steps can be executed in different orders presented in the embodiments of the present application, and it is possible not to execute all the operations in the embodiments of the present application.

[0176] See Figure 12 , which is a flowchart of a communication method provided by the embodiments of the present application. The communication method can include the following steps:

[0177] S1201. The network device sends the first information to the terminal device; correspondingly, the terminal device receives the first information from the network device. The first information indicates a first time-frequency resource, where the first time-frequency resource includes the time-frequency resource for carrying the reference signal of the PUCCH, or the first time-frequency resource includes the time-frequency resource of the PUCCH.

[0178] Exemplarily, the reference signal (RS) of the PUCCH includes but is not limited to DMRS.

[0179] Optionally, the first information is carried in a radio resource control (RRC) signaling.

[0180] S1202. The network device sends the second information to the terminal device; correspondingly, the terminal device receives the second information from the network device. The second information indicates that the terminal device receives the downlink signal on a second time-frequency resource. The second time-frequency resource overlaps with the first time-frequency resource.

[0181] Exemplarily, the downlink signal includes but is not limited to PDSCH and PDCCH.

[0182] Optionally, the second information is carried in the RRC signaling or DCI.

[0183] S1203. The network device sends the downlink signal to the terminal device on a third time-frequency resource; correspondingly, the terminal device receives the downlink signal from the network device on the third time-frequency resource. The third time-frequency resource is the time-frequency resource in the second time-frequency resource except the first time-frequency resource.

[0184] It can be understood that, combining the above steps S1201 to S1203, the first time-frequency resource is not used for transmitting the downlink signal, so the first time-frequency resource can also be regarded as the rate matching pattern of the downlink signal.

[0185] Optionally, the terminal device can send the PUCCH on the first time-frequency resource.

[0186] In the communication method provided by an embodiment of this application, when the first information indicates the first time-frequency resource, if the second time-frequency resource indicated by the second information for transmitting the downlink signal overlaps with the first time-frequency resource, the network device transmits the downlink signal on a third time-frequency resource in the second time-frequency resource other than the first time-frequency resource. That is to say, the first time-frequency resource is not used for transmitting the downlink signal; in addition, since the first time-frequency resource includes the time-frequency resource for carrying the reference signal of the PUCCH, or the first time-frequency resource includes the time-frequency resource of the PUCCH, the terminal device can send the PUCCH or the reference signal of the PUCCH on the first time-frequency resource, which can avoid the CLI caused by the downlink signal to the PUCCH or the reference signal of the PUCCH, thereby improving the reliability of the uplink signal.

[0187] The above is the overall description of the communication method provided by this application. Next, the "time-frequency resource for carrying the reference signal of the PUCCH and the time-frequency resource of the PUCCH" mentioned above will be introduced in detail.

[0188] Optionally, based on different formats of the PUCCH, there are five different implementations of the time-frequency resource of the PUCCH. Among them, the five formats of the PUCCH include PUCCH format 0, PUCCH format 1, PUCCH format 2, PUCCH format 3, and PUCCH format 4.

[0189] Exemplarily, under different formats of the PUCCH, the time-frequency resource of the PUCCH includes the following five implementations:

[0190] (1). The format of the PUCCH is PUCCH format 0:

[0191] Optionally, in the time domain, within one time slot, PUCCH format 0 occupies 1 or 2 symbols. That is to say, when the format of the PUCCH is PUCCH format 0, the PUCCH occupies 1 or 2 symbols within the time slot.

[0192] Exemplarily, when PUCCH format 0 occupies 1 symbol, the starting symbol of PUCCH format 0 can be any symbol within the time slot; when PUCCH format 0 occupies 2 symbols, the starting symbol of PUCCH format 0 can be any symbol from symbol #0 to symbol #13 within the time slot.

[0193] Optionally, in the frequency domain, PUCCH format 0 occupies at least one RB.

[0194] Exemplarily, for frequency range (FR) 1 or FR2-1, PUCCH format 0 occupies 1 resource block (RB); for FR2-2, PUCCH format 0 occupies 1 to 16 RBs.

[0195] Optionally, there is no reference signal (RS) in PUCCH format 0.

[0196] See Figure 13 (i.e., Figure 13 (a) in Figure 13 or (b) in

[0197] Figure 13 Figure 13

[0198] Figure 13 Figure 13

[0199]

[0200]

[0201]

[0202] (2) PUCCH format is PUCCH format 1:

[0200] Optionally, in the time domain, within one time slot, PUCCH format 1 occupies at least 4 symbols. That is to say, when the PUCCH format is PUCCH format 1, PUCCH occupies at least 4 symbols within the time slot.

[0201] Exemplarily, the starting symbol of PUCCH format 1 can be any symbol from symbol #0 to symbol #10 within the time slot.

[0202] Optionally, in the frequency domain, PUCCH format 1 occupies at least one RB.

[0203] Exemplarily, for FR1 or FR2-1, PUCCH format 1 occupies 1 RB; for FR2-2, PUCCH format 1 occupies 1 to 16 RBs.

[0204] Optionally, there are RSs in PUCCH format 1, and they are interleaved with UC1. Further, UCI and RSs occupy different symbols respectively, and they are spaced apart.

[0205] Exemplarily, taking PUCCH format 1 occupying one RB in the frequency domain as an example, as Figure 14 shown, UCI can be carried on the symbols with even indices among the symbols occupied by PUCCH format 1, and RSs can be carried on the symbols with odd indices among the symbols occupied by PUCCH format 1. That is to say, in the time domain, the time-domain resources for carrying RSs of PUCCH are the time-frequency resources corresponding to the symbols with even indices in the time-domain resources of PUCCH; in the frequency domain, the frequency-domain resources for carrying RSs of PUCCH are all the REs in the RBs corresponding to the symbols with even indices among the symbols occupied by PUCCH in the frequency domain.

[0206] It should be noted that the symbol index in the embodiments of this application does not refer to the absolute index, but the relative index, that is, the position of a certain symbol among one or more symbols in the time-domain resources of PUCCH.

[0207] (3). The format of PUCCH is PUCCH format 2:

[0208] Optionally, in the time domain, within one time slot, PUCCH format 2 occupies 1 or 2 symbols.

[0209] Exemplarily, when PUCCH format 0 occupies 1 symbol, the starting symbol of PUCCH format 2 can be any symbol within the time slot; when PUCCH format 2 occupies 2 symbols, the starting symbol of PUCCH format 2 can be any symbol from symbol #0 to symbol #13 within the time slot.

[0210] Optionally, in the frequency domain, PUCCH format 2 occupies at least one RB. Exemplarily, PUCCH format 4 can occupy 1 to 16 RBs.

[0211] Optionally, there is a reference signal (RS) in PUCCH format 2, and the RS is carried in RE#1, RE#4, RE#7, and RE#10 in the resource blocks (RBs) corresponding to each symbol respectively. Exemplarily, taking one RB as an example, as Figure 15 shown, RE#1, RE#4, RE#7, and RE#10 are used to carry the RS; other REs can carry UCI. That is to say, in the time domain, the time domain resources for carrying the RS of PUCCH are all the time-frequency resources in the time domain resources of PUCCH; in the frequency domain, the frequency domain resources for carrying the RS of PUCCH are part of the REs in the RB corresponding to each symbol in the frequency domain resources of PUCCH, namely RE#1, RE#4, RE#7, and RE#10.

[0212] (4) The format of PUCCH is PUCCH format 3:

[0213] Optionally, in the time domain, within one time slot, PUCCH format 3 occupies at least 4 symbols. That is to say, when the format of PUCCH is PUCCH format 3, PUCCH occupies at least 4 symbols within the time slot.

[0214] Exemplarily, the starting symbol of PUCCH format 3 can be any symbol from symbol #0 to symbol #10 within the time slot.

[0215] Optionally, in the frequency domain, PUCCH format 3 occupies at least one RB. Exemplarily, PUCCH format 4 can occupy 1 to 16 RBs.

[0216] (5) The format of PUCCH is PUCCH format 4:

[0217] Optionally, in the time domain, within one time slot, PUCCH format 4 occupies at least 4 symbols. That is to say, when the format of PUCCH is PUCCH format 4, PUCCH occupies at least 4 symbols within the time slot.

[0218] Exemplarily, the starting symbol of PUCCH format 4 can be any symbol from symbol #0 to symbol #10 within the time slot.

[0219] Optionally, in the frequency domain, PUCCH format 4 occupies at least one RB.

[0220] Exemplarily, for FR1 or FR2-1, PUCCH format 4 occupies 1 RB; for FR2-2, PUCCH format 4 occupies 1 to 16 RBs.

[0221] Combined with PUCCH format 3 and PUCCH format 4, optionally, both PUCCH format 3 and PUCCH format 4 have RS. Further, the symbols occupied by RS in PUCCH format 3 and PUCCH format 4 are shown in Table 3 below:

[0222] Table 3

[0223]

[0224] In Table 3 above, the position l of RS in the symbols occupied by PUCCH refers to: in the symbols occupied by PUCCH format 3 (or PUCCH format 4), the index l of the symbol used to carry RS. That is, the index l of the symbol used to carry RS is: the l-th symbol among the symbols occupied by PUCCH format 3 (or PUCCH format 4). Not adding RS and adding RS are different configuration methods of RS. The PUCCH length refers to: the number of symbols occupied by PUCCH format 3 in one time slot. In addition, in the frequency domain, PUCCH format 3 (or PUCCH format 4) is carried in all RBs corresponding to this symbol.

[0225] The above Table 3 is used to indicate the time domain resources of the RS used to carry PUCCH in the time domain resources of PUCCH under PUCCH format 3 or PUCCH format 4, that is, the symbol index of the RS used to carry PUCCH; in the frequency domain, the frequency domain resources of the RS used to carry PUCCH are all the REs in the RBs corresponding to the symbol of the RS used to carry PUCCH in the frequency domain resources of PUCCH.

[0226] Exemplarily, in the case where the PUCCH length is 6, no RS is added, and time-frequency hopping within a time slot is not enabled, as Figure 16 shown, the symbols occupied by PUCCH format 3 include symbol #0 to symbol #5, where symbol #1 and symbol #4 are used to carry RS, and other symbols are used to carry UCI.

[0227] Optionally, PUCCH supports repetition (PUCCH repetition). Specifically, the repetition times N can be 2, 4, 8. Exemplarily, the repetition times refer to: the number of time slots in which PUCCH repetition is configured. N times of PUCCH repetition is expressed as: PUCCH is configured with N consecutive time slots. Among them, as Figure 17 shown, the time-frequency resources configured on each time slot are the same.

[0228] Optionally, the PUCCH supports two types of frequency hopping: intra-slot frequency hopping and inter-slot frequency hopping.

[0229] Exemplarily, intra-slot frequency hopping means that the PUCCH performs frequency hopping within one time slot, that is, the first hop and the second hop are in the same time slot. Among them, the time-frequency resources occupied by the first hop are different from those occupied by the second hop. For example, in the time domain, the time domain resources occupied by the first hop are the first symbols among the symbols configured for the PUCCH within one time slot; the time domain resources occupied by the second hop are the last symbols among the symbols configured for the PUCCH within this time slot. In the frequency domain, the RBs occupied by the first hop and the second hop can be the same or different. Usually, the RBs occupied by the first hop and the second hop are different.

[0230] For example, taking the value of as 14, that is, the PUCCH occupies 14 symbols within one time slot, that is, the number of symbols configured for the PUCCH within one time slot is 14. As Figure 18 shown, within one time slot, the first hop and the second hop respectively occupy the first 7 symbols and the last 7 symbols within the time slot. The starting RBs occupied by the first hop and the second hop are different, and the number of RBs occupied by the first hop and the second hop is the same.

[0231] Exemplarily, PUCCH format 1, PUCCH format 3, and PUCCH format 4 support intra-slot frequency hopping.

[0232] Exemplarily, inter-slot frequency hopping means that within multiple time slots, the PUCCH performs frequency hopping among multiple time slots. That is, the first hop and the second hop are in different time slots. Among them, in the time domain, the time slots occupied by the first hop and the second hop are distributed at intervals; in the frequency domain, the RBs occupied by the first hop and the second hop can be the same or different. Usually, the RBs occupied by the first hop and the second hop are different.

[0233] Specifically, based on whether RS bundling is configured, inter-slot frequency hopping can include the following two implementation methods:

[0234] The first possible implementation method is that when RS bundling is not configured, the time slots occupied by the first hop and the second hop are distributed at intervals. That is, frequency hopping is performed once per time slot.

[0235] Exemplarily, as Figure 19As shown in (a) thereof, in the time domain, the time domain resources occupied by the first hop are the time slots with even indices in the time domain resources configured for PUCCH (such as time slot #0 and time slot #2), and the time domain resources occupied by the second hop are the time slots with odd indices in the time domain resources configured for PUCCH (i.e., time slot #1 and time slot #3); in the frequency domain, the starting RBs occupied by the first hop and the second hop are different, and the number of RBs occupied by the first hop and the second hop is the same.

[0236] The second possible implementation is that, in the case of configuring RS bundling, frequency hopping is performed once every consecutive time slots. It can also be understood as: the number of consecutive time slots with the same frequency domain resources for carrying PUCCH.

[0237] Exemplarily, the value of can be any one of 2, 4, 5, and 10.

[0238] Taking with a value of 2 as an example, as shown in (b) of Figure 19 In the time domain, the time domain resources occupied by the first hop include: time slot #0, time slot #1, time slot #4, time slot #5; the time domain resources occupied by the second hop include: time slot #2, time slot #3, time slot #6, time slot #7. In the frequency domain, the starting RBs occupied by the first hop and the second hop are different, and the number of RBs occupied by the first hop and the second hop is the same.

[0239] The above is the description of the time-frequency resources of PUCCH and the time-frequency resources of RS for carrying PUCCH. Next, the "first time-frequency resource" mentioned in the above embodiments will be introduced in detail.

[0240] Optionally, in combination with the relevant descriptions of the time-frequency resources of PUCCH and the time-frequency resources of RS for carrying PUCCH above, when the format of PUCCH is PUCCH format 0, the first time-frequency resource may include the time-frequency resources of PUCCH. When the format of PUCCH is any one of PUCCH format1, PUCCH format 2, PUCCH format3, or PUCCH format 4, the first time-frequency resource may include the time-frequency resources of PUCCH, or the first time-frequency resource may include the time-frequency resources of RS for carrying PUCCH.

[0241] As an example, the first information directly indicates the first time-frequency resource.

[0242] Optionally, the first information indicates the first symbol set, and / or, the second symbol set. Wherein, the first symbol set and / or the second symbol set are used to determine the first time-frequency resource.

[0243] Optionally, the first symbol set includes at least one symbol. Similarly, the second symbol set includes at least one symbol. Exemplarily, the at least one symbol can be continuous, or the at least one symbol can also be discontinuous.

[0244] Optionally, the first symbol set and the second symbol set can be the same or different.

[0245] Optionally, the first information indicates the first RB set, and / or the second RB set; wherein, the first RB set and / or the second RB set are used to determine the first time-frequency resource.

[0246] Optionally, the first RB set includes at least one RB. Similarly, the second RB set includes at least one RB. Exemplarily, the at least one RB can be continuous, or the at least one RB can also be discontinuous.

[0247] Exemplarily, the first RB set and the second RB set can be the same or different. In other words, the first RB set and the second RB set can overlap, or there may be no overlap between the first RB set and the second RB set.

[0248] Combining the above two optional solutions, the relationships between the first symbol set, the second symbol set, the first RB set, and the second RB set can include the following six possible implementations:

[0249] In the first possible implementation, when the first information indicates the first symbol set and the first RB set, the first symbol set is associated with the first RB set.

[0250] Exemplarily, the first symbol set being associated with the first RB set can be understood as: each symbol in the first symbol set is associated with the first RB set, that is, each symbol can be combined with the first RB set to form a time-frequency resource. Taking the first symbol set including at least one continuous symbol and the first RB set including at least one RB set as an example, the time-frequency resource formed by the first symbol set and the first RB set can be as shown in (a) of Figure 20 For example, the first symbol set includes symbol #1 to symbol #2, and the first RB set includes RB #1 to RB #3. Symbol #1 and RB #1 to RB #3, and symbol #2 and RB #1 to RB #3 can form time-frequency resources.

[0251] In the second possible implementation, when the first information indicates the first symbol set, the first RB set, and the second RB set, the first symbol set is associated with the first RB set and the first symbol set is associated with the second RB set.

[0252] Exemplarily, in this case, the first symbol set is associated with the first RB set and the first symbol set is associated with the second RB set. It can be understood that: some symbols in the first symbol set are associated with the first RB set, and the remaining symbols in the first symbol set are associated with the second RB set.

[0253] Optionally, the first symbol set is associated with the first RB set and the first symbol set is associated with the second RB set, including: the first symbol subset in the first symbol set is associated with the first RB set, and the second symbol subset in the first symbol set is associated with the second RB set, where the first symbol subset and the second symbol subset each include at least one symbol, and there is no overlap between the first symbol subset and the second symbol subset. That is to say, some symbols in the above first symbol set are the first symbol subset, and the remaining symbols in the above first symbol set are the second symbol subset.

[0254] Exemplarily, the first symbol subset is associated with the first RB set, which can be understood as: each symbol in the first symbol subset is associated with the first RB set; similarly, the second symbol subset is associated with the second RB set, which can be understood as: each symbol in the second symbol subset is associated with the second RB set.

[0255] Exemplarily, at least one symbol included in the first symbol subset may be continuous, or at least one symbol included in the first symbol subset may be discontinuous; similarly, at least one symbol included in the second symbol subset may be continuous, or at least one symbol included in the second symbol subset may be discontinuous.

[0256] Exemplarily, the first symbol subset is the same as or different from the second symbol subset. Taking the case where the number of symbols included in the first symbol subset and the second symbol subset is the same, and the symbols included in the first symbol subset and the second symbol subset are all continuous as an example, at this time, the time-frequency resource combined by the first symbol subset and the first RB set can be as shown in (b) in Figure 20 as follows.

[0257] For example, the first symbol set includes symbol #0 to symbol 5. Taking the case where the number of the first symbol subsets is equal as an example, the first symbol subset may include: symbol #0, symbol 2, symbol #4; correspondingly, the second symbol subset may include: symbol #1, symbol 3, symbol #5. Or, the first symbol subset may include: symbol #0 to symbol #2; correspondingly, the second symbol subset may include: symbol #3 to symbol #5.

[0258] In the third possible implementation manner, when the first information indicates the second symbol set and the first RB set, the second symbol set is associated with the first RB set.

[0259] Exemplarily, the second symbol set is associated with the first RB set, which can be understood as: each symbol in the second symbol set is associated with the first RB set, that is, each symbol can be combined with the first RB set to form a time-frequency resource. Specifically, the implementation of the association between the second symbol set and the first RB set is similar to the association between the first symbol set and the first RB set in the above first possible implementation manner, and the relevant description of the above first possible implementation manner can be referred to and will not be elaborated here.

[0260] In the fourth possible implementation manner, when the first information indicates the second symbol set and the first RB set, the second symbol set is associated with the second RB set.

[0261] Exemplarily, the second symbol set is associated with the second RB set, which can be understood as: each symbol in the second symbol set is associated with the second RB set, that is, each symbol can be combined with the second RB set to form a time-frequency resource. Specifically, the implementation of the association between the second symbol set and the second RB set is similar to the association between the first symbol set and the first RB set in the above first possible implementation manner, and the relevant description of the above first possible implementation manner can be referred to and will not be elaborated here.

[0262] The above only exemplarily describes the relationships among the first symbol set, the second symbol set, the first RB set, and the second RB set when the first information indicates the first symbol set or the second symbol set. In fact, the first information can also indicate the first symbol set and the second symbol set. At this time, the relationships among the first symbol set, the second symbol set, the first RB set, and the second RB set can include the following two possible implementation manners:

[0263] In the fifth possible implementation manner, when the first information indicates the first symbol set, the second symbol set, and the first RB set, the first symbol set is associated with the first RB set, and the second symbol set is associated with the first RB set.

[0264] Exemplarily, this possible implementation manner is the combination of the above first possible implementation manner and the second possible implementation manner. Specifically, the relevant descriptions of the above first possible implementation manner and the second possible implementation manner can be referred to and will not be elaborated here.

[0265] Taking the example that the number of symbols included in the first symbol set is the same as that in the second symbol set, and the symbols included in the first symbol set and the second symbol set are both continuous, at this time, the time-frequency resources formed by the combination of the first symbol set and the first RB set, and the time-frequency resources formed by the combination of the second symbol set and the first RB set can be as Figure 21 shown in (a) below.

[0266] In the sixth possible implementation manner, when the first information indicates the first symbol set, the second symbol set, the first RB set, and the second RB set, the first symbol set is associated with the first RB set, and the second symbol set is associated with the second RB set.

[0267] Exemplarily, in this case, the first symbol set is associated with the first RB set, and the second symbol set is associated with the second RB set. It can be understood that each symbol in the first symbol set is associated with the first RB set, and each symbol in the second symbol set is associated with the second RB set.

[0268] Specifically, the implementation of the association between the first symbol set and the first RB set is the same as the implementation of the association between the first symbol set and the first RB set in the above-mentioned first possible implementation manner. The implementation of the association between the second symbol set and the second RB set is similar to the implementation of the association between the first symbol set and the first RB set in the above-mentioned first possible implementation manner. For specific details, reference can be made to the relevant description of the first possible implementation manner above, and details will not be elaborated here.

[0269] Taking the example that the number of symbols included in the first symbol set is the same as that in the second symbol set, and the symbols included in the first symbol set and the second symbol set are all continuous, at this time, the time-frequency resources formed by the combination of the first symbol set and the first RB set, and the time-frequency resources formed by the combination of the second symbol set and the second RB set can be as Figure 21 shown in (b) of

[0270] Based on the above six possible implementation manners, optionally, the first information can also indicate the time-domain resources in the first time-frequency resource in the following two ways:

[0271] As a possible implementation manner, the first information indicates a time slot set, where the time slot set includes at least one time slot, and the time slot set is used to determine the first time-frequency resource.

[0272] Optionally, in this possible implementation manner, at least one time slot can be continuous, or at least one time slot can also be discontinuous.

[0273] Exemplarily, taking the example that at least one time slot is continuous, the first information can indicate the number of at least one time slot and the starting position of at least one time slot. Among them, the number of at least one time slot can be any one of 1, 2, 4, and 8.

[0274] In the first example, when the first information further indicates the first symbol set, each time slot in the time slot set includes the first symbol set.

[0275] In the second example, the first information further indicates that in the case of the first symbol set and the second symbol set, each time slot in the time slot set includes the first symbol set and the second symbol set. Alternatively, each time slot in the first time slot subset of the time slot set includes the first symbol set, and each time slot in the second time slot subset of the time slot set includes the second symbol set. The first time slot subset and the second time slot subset each include at least one time slot, and there is no overlap between the first time slot subset and the second time slot subset.

[0276] Exemplarily, the at least one time slot included in the first time slot subset and the second time slot subset is continuous, or the at least one time slot included in the first time slot subset and the second time slot subset is discontinuous.

[0277] In the third example, the first information further indicates that in the case of the second symbol set, each time slot in the time slot set includes the second symbol set.

[0278] Combining the above three examples, the first time-frequency resource can be implemented based on the following two schemes:

[0279] Scheme 1: The first information further indicates the hopping pattern of the PUCCH, and the hopping pattern of the PUCCH is used to determine the first time-frequency resource. Among them, the hopping pattern includes disabled hopping, in-slot hopping, and inter-slot hopping.

[0280] Exemplarily, the hopping pattern of the PUCCH can be represented by 2 bits. For example, when the value of the 2 bits is 00, it indicates that the hopping pattern of the PUCCH is disabled hopping; when the value of the 2 bits is 01, it indicates that the hopping pattern of the PUCCH is in-slot hopping; when the value of the 2 bits is 10, it indicates that the hopping pattern of the PUCCH is inter-slot hopping. Alternatively, the first information can also indicate the hopping pattern of the PUCCH in other ways, which is not limited in the embodiments of the present application.

[0281] Optionally, under Scheme 1, at least one symbol included in symbol set #A is continuous. Symbol set #A can be the first symbol set or the second symbol set.

[0282] Exemplarily, symbol set #A can be represented by a starting symbol and a symbol length. For example, if the first information indicates that the starting symbol is symbol #2 and the symbol length is 4, then symbol set #A includes 4 consecutive symbols starting from symbol #2, that is, symbol set #A includes symbols #2 to #5.

[0283] Optionally, under Scheme 1, at least one RB included in RB set #A is continuous. RB set #A can be the first RB set or the second RB set.

[0284] Exemplarily, the RB set #A can be represented by the starting RB and the RB length. For example, the first piece of information indicates that the starting RB is RB#2 and the RB length is 4. At this time, the RB set #A includes 4 consecutive symbols starting from RB#2, that is, the RB set #A includes RB#2 to RB#5.

[0285] Optionally, the first piece of information further indicates the format of the PUCCH. The format of the PUCCH is used to determine the first time-frequency resource.

[0286] Exemplarily, under different formats of the PUCCH, the time-frequency resources of the PUCCH are different, and the time-frequency resources for carrying the RS of the PUCCH are also different. Specifically, the correspondence between the format of the PUCCH and the time-frequency resources of the PUCCH, or the time-frequency resources for carrying the RS of the PUCCH, can refer to the relevant descriptions above Figures 13 to 19 and will not be elaborated here.

[0287] Exemplarily, the first piece of information can indicate any one of PUCCH format 0, PUCCH format 1, PUCCH format 2, PUCCH format 3, and PUCCH format 4.

[0288] Specifically, the first piece of information can be represented by 3 bits. Among them, different values of the 3 bits respectively represent different formats of the PUCCH. For example, when the value of the 3 bits is 000, it means that the first piece of information indicates PUCCH format 0; when the value of the 3 bits is 001, it means that the first piece of information indicates PUCCH format 1;...; when the value of the 3 bits is 100, it means that the first piece of information indicates PUCCH format 4. Alternatively, the first piece of information can also indicate the format of the PUCCH in other ways, which is not limited in the embodiments of the present application.

[0289] Based on this optional solution, since the configuration ranges of the time-frequency resources of the PUCCH are different under different formats of the PUCCH; thus, the AP can indicate the time-frequency resources of the PUCCH or the time-frequency resources for carrying the RS of the PUCCH by indicating the format of the PUCCH, and further indicate the first time-frequency resource; so that the first time-frequency resource includes the time-frequency resources of the PUCCH or the time-frequency resources for carrying the RS of the PUCCH. Since downlink signals cannot be transmitted on the first time-frequency resource, the terminal device can send the PUCCH or the reference signal of the PUCCH on the first time-frequency resource, which can avoid the interference of the downlink signal on the PDSCH to the PUCCH or the reference signal of the PUCCH, thereby improving the reliability of the PUCCH.

[0290] Optionally, the first information may further indicate the time-frequency resource for carrying the reference signal of the PUCCH, and the time-frequency resource for carrying the reference signal of the PUCCH is used to indicate the first time-frequency resource.

[0291] Exemplarily, when the format of the PUCCH is PUCCH format 2, the frequency-domain resources for carrying the reference signal of the PUCCH are RE#1, RE#4, RE#7, and RE#10 in the frequency-domain resources of the PUCCH. When the format of the PUCCH is PUCCH format 1, the time-frequency resource for carrying the reference signal of the PUCCH is the time-domain resource formed by combining the symbols with even symbol indices in the time-frequency resources of the PUCCH and all the corresponding RBs. That is, when the format of the PUCCH is PUCCH format 1 or PUCCH format 2, the first information realizes indicating the time-frequency resource for carrying the reference signal of the PUCCH by indicating the format of the PUCCH.

[0292] Exemplarily, when the format of the PUCCH is PUCCH format 3 or PUCCH format 4, the first information may further indicate whether DMRS is appended to the PUCCH. Combining with the frequency hopping mode of the PUCCH, the time-frequency resource for carrying the reference signal of the PUCCH can be determined. Specifically, refer to the relevant descriptions shown above and will not be elaborated here.

[0293] Combined with the above Figures 13 to 19 According to the relevant descriptions, the frequency-domain resources of the time-frequency resources of the PUCCH may include at least one RE in the RB. For example, when the format of the PUCCH is any one of PUCCH format 1, PUCCH format 3, or PUCCH format 4, the at least one RE includes all the REs in the RB. When the format of the PUCCH is PUCCH format 2, the at least one RE includes at least RE#1, RE#4, RE#7, and RE#10 in the RB. For the convenience of description, hereinafter, the at least one RE is simply referred to as the RE set, which is uniformly described here and will not be elaborated further.

[0294] In a possible implementation manner, when the frequency hopping mode is not enabled for frequency hopping, the first information may indicate the first RB set.

[0295] One implementation manner is that, in this possible implementation manner, the first information further indicates the first symbol set. At this time, each time slot in the time slot set includes the first symbol set, and the relationship between the first symbol set and the first RB set satisfies the content described in the above first possible implementation manner.

[0296] Optionally, in this implementation manner, the first time-frequency resource includes a time-frequency resource formed by combining the first symbol set included in each time slot in the time slot set with the RE set in the first RB set.

[0297] Exemplarily, taking the first symbol set including at least one consecutive symbol and the first RB set including at least one consecutive RB as an example, based on Figure 20 the relationship between the first symbol set and the first RB set shown in (a) in Figure 22 the first time-frequency resource in the time slot set may be as shown in (a) in

[0298] Another implementation manner is that in this possible implementation manner, the first information further indicates the first symbol set and the second symbol set. At this time, each time slot in the time slot set includes the first symbol set and the second symbol set, and the relationships between the first symbol set and the first RB set, and between the second symbol set and the first RB set satisfy the content described in the above fifth possible implementation manner.

[0299] Optionally, in this implementation manner, the first time-frequency resource includes a time-frequency resource formed by combining the first symbol set included in each time slot in the time slot set with the RE set in the first RB set, and a time-frequency resource formed by combining the second symbol set included in each time slot in the time slot set with the RE set in the first RB set.

[0300] Optionally, in this implementation manner, the first symbol set is different from the second symbol set.

[0301] Exemplarily, taking the first symbol set and the second symbol set respectively including at least one consecutive symbol and the first RB set including at least one consecutive RB as an example, based on Figure 21 the relationship between the first symbol set and the first RB set, and between the second symbol set and the first RB set shown in (a) in Figure 22 the first time-frequency resource in the time slot set may be as shown in (b) in

[0302] Yet another implementation manner is that in this possible implementation manner, the first information further indicates the second symbol set. At this time, each time slot in the time slot set includes the second symbol set; the relationship between the second symbol set and the first RB set satisfies the content described in the above third possible implementation manner.

[0303] Optionally, in this implementation manner, the first time-frequency resource includes a time-frequency resource formed by combining the second symbol set included in each time slot in the time slot set with the RE set in the first RB set.

[0304] Exemplarily, taking the second symbol set including at least one continuous symbol and the first RB set including at least one continuous RB as an example, based on the relationship between the second symbol set and the first RB set in the above-mentioned third possible implementation manner, the first time-frequency resource in the time slot set can be as Figure 22 shown in (c) of

[0305] In another possible implementation manner, when the frequency hopping mode is in-slot frequency hopping, the first information may indicate the first RB set and the second RB set.

[0306] Optionally, in this possible implementation manner, the starting RBs of the first RB set and the second RB set are different.

[0307] One implementation manner is that, in this possible implementation manner, the first information further indicates the first symbol set. At this time, each time slot in the time slot set includes the first symbol set; the relationships between the first symbol set and the first RB set, and between the first symbol set and the second RB satisfy the content described in the above-mentioned second possible implementation manner.

[0308] Optionally, in this implementation manner, the number of symbols included in the first symbol subset and the second symbol subset is the same. The first symbol subset includes the first half of the symbols in the first symbol set, and the second symbol subset includes the second half of the symbols in the first symbol set.

[0309] Optionally, in this implementation manner, the first time-frequency resource includes the time-frequency resource formed by combining the first symbol subset included in each time slot in the time slot set with the RE set in the first RB set, and the time-frequency resource formed by combining the second symbol subset included in each time slot in the time slot set with the RE set in the second RB set.

[0310] Exemplarily, taking the first symbol subset and the second symbol subset respectively including at least one continuous symbol and the first RB set including at least one continuous RB as an example, based on Figure 20 the relationships between the first symbol subset and the first RB set, and between the second symbol subset and the second RB set shown in (b) of Figure 23 the first time-frequency resource in the time slot set can be as

[0311] shown in (a) of

[0312] Another implementation manner is that, in this possible implementation manner, the first information further indicates the second symbol set. At this time, each time slot in the time slot set includes the first symbol set and the second symbol set; the relationships between the second symbol set and the first RB set, and between the second symbol set and the second RB satisfy the content described in the above-mentioned fourth possible implementation manner.

[0312] Exemplarily, in this implementation manner, the implementation of the first time-frequency resource is the same as the above-mentioned Figure 23is similar to the implementation of the first time-frequency resource shown in (a) of [], and it is only necessary to replace the first symbol subset in (a) of [] with the first symbol set and the second symbol subset with the second symbol set. Figure 23 Replace the first symbol subset in (a) of [] with the first symbol set and the second symbol subset with the second symbol set.

[0313] Another implementation method is that in this possible implementation method, the first information also indicates the first symbol set and the second symbol set. At this time, each time slot in the time slot set includes the first symbol set and the second symbol set; the relationship between the first symbol set and the first RB set, and the second symbol set and the second RB set satisfies the content described in the above sixth possible implementation method.

[0314] Optionally, in this implementation method, the first symbol set and the second symbol set include the same number of symbols, the starting symbols of the first symbol set and the second symbol set are different, and the last symbol in the first symbol set is consecutive with the first symbol in the second symbol set.

[0315] Optionally, in this implementation method, the first time-frequency resource includes the time-frequency resource combined by the first symbol set included in each time slot and the RE set in the first RB set, and the time-frequency resource combined by the second symbol set included in each time slot and the second RB set.

[0316] Exemplarily, taking the first symbol set and the second symbol set each including at least one consecutive symbol and the first RB set including at least one consecutive RB as an example, based on Figure 21 the relationship between the first symbol set and the first RB set, and the second symbol set and the second RB set shown in (b) of [], the first time-frequency resource in the time slot set is similar to Figure 23 the first time-frequency resource shown in (a) of [], and replace Figure 23 the first symbol subset shown in (a) of [] with the first symbol set and the second symbol subset with the second symbol set, that is, making Figure 23 the time-frequency resource shown in (a) of [] be the first time-frequency resource in this implementation method.

[0317] In another possible implementation method, when the frequency hopping method is inter-slot frequency hopping, the first information may indicate the first RB set and the second RB set.

[0318] Optionally, in this possible implementation method, the starting RBs of the first RB set and the second RB set are different.

[0319] Optionally, in this possible implementation manner, the first information further indicates a first symbol set and a second symbol set. At this time, each time slot in the first time slot subset of the time slot set includes the first symbol set, and each time slot in the second time slot subset includes the second symbol set; the relationships between the first symbol set and the first RB set, and between the second symbol set and the second RB set satisfy the content described in the sixth possible implementation manner above.

[0320] Optionally, in this possible implementation manner, the first information further indicates whether the PUCCH supports reference signal bundling. When the PUCCH supports reference signal bundling, the first information further indicates the number of time slots, and the number of time slots is used to determine the first time slot subset and the second time slot subset.

[0321] Exemplarily, the number of time slots refers to: in the time slot set, the number of time slots corresponding to the same frequency domain resource continuously occupied in the time-frequency resource of the PUCCH. That is, frequency hopping is performed every other such number of time slots. For example, Figure 19 as shown in (b) of, at this time, it can be considered that the value of the number of time slots is 2.

[0322] Optionally, the value of the number of time slots can be any one of 2, 4, 5, and 10.

[0323] Optionally, in this possible implementation manner, when the PUCCH does not support reference signal bundling, it is default that frequency hopping is performed once per time slot. That is, as Figure 19 shown in (a) of, the symbol set associated with the second RB and the symbol set associated with the first RB are located in adjacent time slots.

[0324] Optionally, in this possible implementation manner, the number of time slots included in the first time slot subset and the second time slot subset may be the same or different. There is no overlap between the first time slot subset and the second time slot subset.

[0325] Optionally, in this possible implementation manner, the first time-frequency resource includes the time-frequency resource formed by combining the first symbol set included in each time slot in the first time slot subset with the RE set in the first RB set, and the time-frequency resource formed by combining the second symbol set included in each time slot in the second time slot subset with the RE set in the second RB set.

[0326] Exemplarily, taking the first symbol set and the second symbol set each including at least one continuous symbol, and the first RB set including at least one continuous RB as an example, based on Figure 21 the relationships between the first symbol set and the first RB set, and between the second symbol set and the second RB set shown in (b) of, when the PUCCH does not support reference signal bundling, in the time slot set, the first time-frequency resource includes as Figure 23as shown in (b) thereof; when PUCCH supports reference signal bundling and the number of time slots is 2, the first time-frequency resource in the time slot set includes as shown in Figure 23 in (c) thereof.

[0327] Solution 2: directly determine the first time-frequency resource by combining the above three examples.

[0328] Optionally, the first information further indicates a first time slot subset and a second time slot subset.

[0329] Exemplarily, the time slot subset #A can be represented by a bitmap. The time slot subset #A can be the first time slot subset or the second time slot subset.

[0330] Where the number of bits of the bitmap is the same as the number of time slots included in the time slot set. For example, taking the time slots in the time slot subset #A being represented by a bit value of 1 as an example, if the bitmap is 0101, it means that the time slot subset #A includes 4 consecutive symbols, and the time slot subset #A includes the second symbol and the fourth symbol.

[0331] Optionally, the first information can also indicate a set of resource elements (REs). The set of REs includes at least one RE.

[0332] Exemplarily, at least one RE can include all the REs in one resource block (RB), or at least one RE can include a part of the REs in one RB.

[0333] Exemplarily, the set of REs can be represented by a bitmap, and the bitmap can be represented by 12 bits. Taking at least one RE including a part of the REs in one RB as an example, for example, taking the REs in the set of REs being represented by a bit value of 1 as an example, if the bitmap is 010010010010, it means that the first set of REs includes RE#1, RE#4, RE#7, and RE#10. Or, the REs in the set of REs are indicated by the bit value being "0". Exemplarily, the implementation of at least one RE can be as shown in Figure 20 or Figure 21 shown.

[0334] Optionally, under Solution 2, at least one symbol included in the symbol set #A can be consecutive. Or, at least one symbol included in the symbol set #A can also be non-consecutive. The symbol set #A can be the first symbol set or the second symbol set.

[0335] Optionally, the number of at least one symbol included in the symbol set #A is less than or equal to 14.

[0336] For example, when the format of PUCCH is PUCCH format 0 or PUCCH format 2, the number of at least one symbol included in symbol set #A can be 1 or 2; when the format of PUCCH is any one of PUCCH format 1, PUCCH format 3, or PUCCH format 4, the number of at least one symbol included in symbol set #A can be any one of 4 - 14.

[0337] Exemplarily, symbol set #A can be represented by a bit map. The bit map can be represented by 14 bits. For example, taking the symbol in symbol set #A being represented by a bit value of 1 as an example, if the bit map is 01110000000000, it means that symbol set #A includes 3 consecutive symbols, and the starting symbol among the 3 consecutive symbols is the second symbol within a time slot; if the bit map is 01010100000000, it means that symbol set #A includes 3 non - consecutive symbols, and the 3 non - consecutive symbols are respectively the second symbol, the fourth symbol, and the sixth symbol within a time slot.

[0338] Optionally, at least one RB included in RB set #A can be consecutive, or at least one RB included in RB set #A can also be non - consecutive. RB set #A can be the first RB set or the second RB set.

[0339] Exemplarily, when the format of PUCCH is PUCCH format 2, at least one RB included in RB set #A can be non - consecutive; when the format of PUCCH is any one of PUCCH format 1, PUCCH format 3, or PUCCH format 4, at least one RB included in RB set #A can be non - consecutive.

[0340] Exemplarily, taking at least one RB included in RB set #A being consecutive as an example, RB set #A can be represented by a starting RB and an RB length. For example, the first information indicates that the starting RB is RB#2 and the RB length is 4. At this time, RB set #A includes 4 consecutive symbols starting from RB#2, that is, RB set #A includes RB#2 to RB#5.

[0341] Optionally, the number of at least one RB included in RB set #A is less than or equal to 16.

[0342] Exemplarily, under Solution 2, the first time - frequency resource can be implemented based on the following six cases:

[0343] Case 1: The first information can indicate the first symbol set and the first RB set.

[0344] Optionally, each time slot in the time slot set includes a first symbol set, and the relationship between the first symbol set and the first RB set satisfies the content described in the first possible implementation manner as above.

[0345] Optionally, the first time-frequency resource includes a time-frequency resource formed by combining the first symbol set included in each time slot in the time slot set and the RE set in the first RB set.

[0346] Exemplarily, taking the first symbol set including at least one consecutive symbol and the first RB set including at least one consecutive RB as an example, the first time-frequency resource in the time slot set may be as shown in (a) in Figure 22 .

[0347] Case 2: The first information may indicate the first symbol set, the second symbol set, and the first RB set.

[0348] Optionally, each time slot in the time slot set includes a first symbol set and a second symbol set, and the relationships between the first symbol set and the first RB set, and between the second symbol set and the first RB set satisfy the content described in the fifth possible implementation manner as above.

[0349] Optionally, in Case 2, the first symbol set is different from the second symbol set. And the total number of symbols included in the first symbol set and the second symbol set is less than or equal to 14.

[0350] Optionally, the first time-frequency resource includes a time-frequency resource formed by combining the first symbol set included in each time slot in the time slot set and the RE set in the first RB set, and a time-frequency resource formed by combining the second symbol set included in each time slot in the time slot set and the RE set in the first RB set.

[0351] Exemplarily, taking the first symbol set and the second symbol set each including at least one consecutive symbol and the first RB set including at least one consecutive RB as an example, the first time-frequency resource in the time slot set may be as shown in (b) in Figure 22 .

[0352] Combining Case 1 and Case 2, exemplarily, the first time-frequency resource may include the time-frequency resource of PUCCH format 0, or the time-frequency resource of PUCCH under any one of PUCCH format 1 to PUCCH format 4 without enabling frequency hopping, or the time-frequency resource for carrying the RS of PUCCH.

[0353] Case 3: The first information may indicate the first symbol set, the second symbol set, the first RB set, and the second RB set.

[0354] Optionally, the starting RBs of the first RB set and the second RB set are different.

[0355] Optionally, the relationships between the first symbol set and the first RB set, and between the second symbol set and the first RB set satisfy the content described in the sixth possible implementation manner as above.

[0356] In one implementation manner, each time slot in the time slot set includes a first symbol set and a second symbol set.

[0357] Optionally, the first time-frequency resource includes the time-frequency resource formed by combining the first symbol set included in each time slot in the time slot set with the RE set in the first RB set, and the time-frequency resource formed by combining the second symbol set included in each time slot in the time slot set with the RE set in the second RB set.

[0358] Optionally, the first symbol set and the second symbol set are different. And the total number of symbols included in the first symbol set and the second symbol set is less than or equal to 14.

[0359] Exemplarily, taking the first symbol set and the second symbol set each including at least one continuous symbol, and the first RB set including at least one continuous RB as an example, in the time slot set, the first time-frequency resource is similar to the first time-frequency resource shown in (a) in Figure 23 , replacing the first symbol subset shown in (a) in Figure 23 with the first symbol set, and replacing the second symbol subset with the second symbol set, that is, making the time-frequency resource shown in (a) in Figure 23 be the first time-frequency resource in this implementation manner.

[0360] Exemplarily, the first time-frequency resource may include the time-frequency resource of the PUCCH under any one of PUCCH format 1, PUCCH format 3, or PUCCH format 4 or the time-frequency resource of the RS for carrying the PUCCH in the case of enabling frequency hopping within a time slot.

[0361] In another implementation manner, each time slot in the first time slot subset in the time slot set includes a first symbol set, and each time slot in the second time slot subset includes a second symbol set.

[0362] Optionally, in this implementation manner, the continuous time slots where the first symbol set is located and the continuous time slots where the second symbol set is located are distributed at intervals, that is, every X time slots in the time slot set are associated with different symbol sets, where X is a positive integer.

[0363] Exemplarily, taking the time slot set including 8 consecutive time slots as an example, if the value of X is 1, the first time slot subset may include time slot #0, time slot #2, time slot #4, time slot #6, time slot #8; the second time slot subset may include time slot #1, time slot #3, time slot #5, time slot #7, time slot #9. At this time, it can also be considered that the time slots in the first time slot subset are distributed at intervals from the time slots in the second time slot subset.

[0364] If the value of X is 3, the first time slot subset may include time slot #0, time slot #1, time slot #2, time slot #6, time slot #7; the second time slot subset may include time slot #3, time slot #4, time slot #5.

[0365] Optionally, in this implementation manner, the first time-frequency resource includes the time-frequency resource formed by combining the first symbol set included in each time slot in the first time slot subset with the RE set in the first RB set, and the time-frequency resource formed by combining the second symbol set included in each time slot in the second time slot subset with the RE set in the second RB set.

[0366] Exemplarily, if the value of X is 1, the first time-frequency resource in the time slot set is as shown in (b) of Figure 23 , if the value of X is 2, the first time-frequency resource in the time slot set is as shown in (a) of Figure 23 . At this time, it can also be considered that the time-frequency resource formed by combining the first symbol set included in each time slot in the first time slot subset with the RE set in the first RB set is the first hop, and the time-frequency resource formed by combining the second symbol set included in each time slot in the second time slot subset with the RE set in the second RB set is the second hop.

[0367] Exemplarily, the first time-frequency resource may include the time-frequency resource of the PUCCH under any one of PUCCH format 2 or PUCCH format 3 or the time-frequency resource of the RS for carrying the PUCCH in the case of enabling inter-slot frequency hopping.

[0368] Case 4: The first information may indicate the first symbol set, the first RB set, and the second RB set.

[0369] Optionally, the relationship between the first symbol set and the first RB set, and between the first symbol set and the second RB satisfies the content described in the above second possible implementation manner.

[0370] Optionally, the starting RBs of the first RB set and the second RB set are different.

[0371] Optionally, the number of symbols included in the first symbol subset and the second symbol subset is the same. The first symbol subset includes the first half of the symbols in the first symbol set, and the second symbol subset includes the second half of the symbols in the first symbol set.

[0372] Optionally, in this implementation manner, the first time-frequency resource includes the time-frequency resource combined by the first symbol subset included in each time slot in the time slot set and the RE set in the first RB set, and the time-frequency resource combined by the second symbol subset included in each time slot in the time slot set and the RE set in the second RB set.

[0373] Exemplarily, taking the first symbol subset and the second symbol subset each including at least one consecutive symbol, and the first RB set including at least one consecutive RB as an example, in the time slot set, the first time-frequency resource may be as shown in (a) in Figure 23 .

[0374] Exemplarily, the first time-frequency resource may include the time-frequency resource of the PUCCH under any one of PUCCH format 1, PUCCH format 3, or PUCCH format 4 or the time-frequency resource of the RS for carrying the PUCCH in the case of enabling frequency hopping within a time slot.

[0375] Case Five: The first information may indicate the second symbol set, the first RB set, and the second RB set.

[0376] Optionally, the relationship between the second symbol set and the first RB set, and the relationship between the second symbol set and the second RB satisfy the content described in the above fourth possible implementation manner.

[0377] Exemplarily, the implementation of the second symbol set in Case Five is similar to the implementation of the first symbol set in Case Four above. Therefore, the implementation of the first time-frequency resource in Case Five is similar to the implementation of the first time-frequency resource in Case Four above. For specific reference, please refer to the relevant description in Case Four and will not be elaborated here.

[0378] Case Six: The first information may indicate the second symbol set and the first RB set.

[0379] Optionally, the relationship between the second symbol set and the first RB set satisfies the content described in the above third possible implementation manner.

[0380] Exemplarily, the implementation of the second symbol set in Case Six is similar to the implementation of the first symbol set in Case One above. Therefore, the implementation of the first time-frequency resource in Case Six is similar to the implementation of the first time-frequency resource in Case One above. For specific reference, please refer to the relevant description in Case One and will not be elaborated here.

[0381] As another possible implementation manner, the first information indicates a set of time units, where the set of time units includes at least one time unit. Each time unit includes at least one time slot, and the set of time units is used to indicate the first time-frequency resource.

[0382] Optionally, at least one time unit may be continuous.

[0383] Optionally, in this possible implementation, at least one time slot may be continuous, or at least one time slot may also be discontinuous.

[0384] Exemplarily, taking the case where at least one time slot is continuous as an example, the first information may further indicate the number of at least one time unit and the starting position of at least one time unit. Among them, the number of at least one time unit may be any one of 1, 2, 4, and 8.

[0385] Exemplarily, the number of time slots included in each time unit in at least one time unit may be any one of 1, 2, 4, and 8.

[0386] Optionally, in this possible implementation, the first information may further indicate a RE set. The RE set includes at least one RE.

[0387] Exemplarily, the implementation of the RE set is the same as the implementation of the RE set in the above Solution 2. Specifically, reference may be made to the relevant description of the above Solution 2, which will not be elaborated here.

[0388] Optionally, in this possible implementation, at least one symbol included in the symbol set #A may be continuous. Or, at least one symbol included in the symbol set #A may also be discontinuous. The symbol set #A may be a first symbol set or a second symbol set.

[0389] Optionally, the number of at least one symbol included in the symbol set #A is less than or equal to the total number of symbols included in one time unit.

[0390] Taking the case where one time unit includes 2 time slots and each time slot includes 14 symbols as an example, when the format of PUCCH is PUCCH format 0 or PUCCH format 2, the number of at least one symbol included in the symbol set #A may be 2 or 4; when the format of PUCCH is any one of PUCCH format 1, PUCCH format 3, or PUCCH format 4, the number of at least one symbol included in the symbol set #A may be any one of 8 - 28.

[0391] Exemplarily, the symbol set #A may be represented by a bit map. The number of bits of the bit map is the same as the total number of symbols included in one time unit.

[0392] Taking a time that includes 2 time slots, and each time slot includes 14 symbols. Taking the case where a symbol in symbol set #A is represented by a bit value of 1 as an example, if the bit map is 0111000000000001110000000000, it means that symbol set #A includes 6 symbols, and the 6 symbols are respectively the second symbol, the fourth symbol, the sixth symbol, the sixteenth symbol, the seventeenth symbol, and the eighteenth symbol within one time unit.

[0393] Optionally, at least one RB included in RB set #A can be continuous, or at least one RB included in RB set #A can also be discontinuous. RB set #A can be the first RB set or the second RB set.

[0394] Exemplarily, the implementation of RB set #A is the same as that of RB set #A in the above-mentioned second solution. Specifically, reference can be made to the relevant description of the above-mentioned second solution, which will not be elaborated here.

[0395] In the first example, when the first information further indicates the first symbol set, each time unit in the time unit set includes the first symbol set.

[0396] In the second example, when the first information further indicates the first symbol set and the second symbol set, each time unit in the time unit set includes the first symbol set and the second symbol set.

[0397] Exemplarily, at least one time slot included in the first time slot subset and the second time slot subset is continuous, or at least one time slot included in the first time slot subset and the second time slot subset is discontinuous.

[0398] In the third example, when the first information further indicates the second symbol set, each time unit in the time unit set includes the second symbol set.

[0399] Combining the above three examples, the first time-frequency resource can be implemented based on the following six cases:

[0400] Case 1: The first information can indicate the first symbol set and the first RB set.

[0401] Optionally, each time unit in the time unit set includes the first symbol set, and the relationship between the first symbol set and the first RB set satisfies the content described in the above-mentioned first possible implementation manner.

[0402] Optionally, the first time-frequency resource includes the time-frequency resource combined by the RE sets in the first symbol set included in each time unit in the time unit set and the first RB set.

[0403] Exemplarily, taking the first symbol set including at least one symbol and the first RB set including at least one consecutive RB as an example, in the time unit set, the first time-frequency resource may be as shown in (a) of Figure 24 .

[0404] Case 2: The first information may indicate the first symbol set, the second symbol set, and the first RB set.

[0405] Optionally, each time unit in the time unit set includes the first symbol set and the second symbol set, and the relationships between the first symbol set and the first RB set, and between the second symbol set and the first RB set satisfy the content described in the above fifth possible implementation manner.

[0406] Optionally, the first symbol set is different from the second symbol set, and the total number of symbols included in the first symbol set and the second symbol set is less than or equal to the number of symbols included in one time unit.

[0407] Optionally, the first time-frequency resource includes the time-frequency resource combined by the RE set in the first RB set and the first symbol set included in each time unit in the time unit set, and the time-frequency resource combined by the RE set in the first RB set and the second symbol set included in each time unit in the time unit set.

[0408] Exemplarily, taking the first symbol set and the second symbol set each including at least one symbol and the first RB set including at least one consecutive RB as an example, in the time unit set, the first time-frequency resource may be as shown in (b) of Figure 24 .

[0444] As another example, the first information indirectly indicates the first time-frequency resource.

[0445] In a possible implementation manner, the first indication information indicates a first set, the first set includes at least one time-frequency resource, and the at least one time-frequency resource includes the first time-frequency resource.

[0446] Optionally, in this possible implementation manner, the first set can be periodic, semi-persistent, or aperiodic.

[0455] Optionally, the third information is carried in a media access control-control element (MAC-CE) signaling or DCI.

[0456] Optionally, when the third information is carried in DCI and the first time-frequency resource is aperiodic, the third information further indicates a first offset. The first offset is used to indicate the starting position of the first time-frequency resource in the first set (or the second set).

[0457] Exemplarily, the first offset is the deviation between the starting position of the first time-frequency resource (i.e., the first time slot in the first time-frequency resource) and the time slot used to carry the DCI.

[0458] Optionally, the first offset is one of the offset values in an offset set. Exemplarily, the offset set may be indicated by the first information.

[0471] All relevant contents of the steps involved in the above method embodiments can be cited in the function descriptions of the corresponding functional modules and will not be elaborated here.

[0472] In this application, the communication device 260 may be presented in the form of integrating and dividing each functional module. Here, a "module" may refer to an application-specific integrated circuit (ASIC), a circuit, a processor and a memory that execute one or more software or firmware programs, an integrated logic circuit, and / or other devices that can provide the above functions.

[0473] In some embodiments, when Figure 26 the communication device 260 in is a chip or a chip system, the function / implementation process of the transceiver module 2602 may be implemented through the input / output interface (or communication interface) of the chip or the chip system, and the function / implementation process of the processing module 2601 may be implemented through the processor (or processing circuit) of the chip or the chip system.

[0474] Since the communication device 260 provided in this embodiment can execute the above method, the technical effects it can obtain can refer to the above method embodiments and will not be elaborated here.

[0475] As a possible product form, the terminal device or network device described in the embodiments of the present application can also be implemented using the following: one or more field programmable gate arrays (FPGAs), programmable logic devices (PLDs), controllers, state machines, gate logic, discrete hardware components, any other suitable circuits, or any combination of circuits capable of performing the various functions described throughout the present application.

[0476] As another possible product form, the terminal device or network device described in the embodiments of the present application can be implemented by a general bus architecture. For ease of explanation, refer to Figure 27 , Figure 27 FIG. 10 is a schematic structural diagram of a communication device 2700 provided in an embodiment of the present application. The communication device 2700 includes a processor 2701 and a transceiver 2702. The communication device 2700 can be a network device, or a chip or chip system therein; or, the communication device 2700 can be a terminal device, or a chip or module therein. Figure 27 Only the main components of the communication device 2700 are shown. In addition to the processor 2701 and the transceiver 2702, the communication device may further include a memory 2703 and an input / output device (not shown in the figure).

[0477] Optionally, the processor 2701 is mainly used to process communication protocols and communication data, control the entire communication device, execute software programs, and process data of software programs. The memory 2703 is mainly used to store software programs and data. The transceiver 2702 may include a radio frequency circuit and an antenna. The radio frequency circuit is mainly used for the conversion between baseband signals and radio frequency signals and the processing of radio frequency signals. The antenna is mainly used to transmit and receive radio frequency signals in the form of electromagnetic waves. The input / output device, such as a touch screen, a display screen, a keyboard, etc., is mainly used to receive data input by the user and output data to the user.

[0478] Optionally, the processor 2701, the transceiver 2702, and the memory 2703 can be connected through a communication bus.

[0479] After the communication device is powered on, the processor 2701 can read the software program in the memory 2703, interpret and execute the instructions of the software program, and process the data of the software program. When data needs to be wirelessly transmitted, after the processor 2701 performs baseband processing on the data to be transmitted, it outputs a baseband signal to the radio frequency circuit. The radio frequency circuit performs radio frequency processing on the baseband signal and then transmits the radio frequency signal outward in the form of electromagnetic waves through the antenna. When data is sent to the communication device, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor 2701. The processor 2701 converts the baseband signal into data and processes the data.
