To facilitate the understanding of the embodiments of the present application, a brief description of several terms involved in the present application will be given first.

1. Ability information

The capability of the terminal device or the capability information of the terminal device may indicate the processing time capability of the terminal device, or in other words, the downlink data processing time capability of the terminal device.

For example, the terminal device may support capability 1 or capability 2. In other words, the capability information reported by the terminal device may indicate that the terminal device supports capability 1 or capability 2. The downlink data processing time of the terminal equipment is related to the parameter N1. Different capabilities correspond to different N1s, such as N1 corresponding to capability 1 and N1 corresponding to capability 2 are different. In other words, when the terminal device supports capability 1, the downlink data processing time of the terminal device is determined based on N1 corresponding to capability 1, and when the terminal device supports capability 2, the downlink data processing time of the terminal device is based on N1 corresponding to capability 2. determine. The specific description will be given below in conjunction with the description of the downlink data processing time.

In the embodiment of this application, the terminal device may also support capability 3. This capability 3 is different from the existing capability 1 and capability 2, and capability 3 can represent the capability under multi-station transmission. Specific examples are introduced below.

2. HARQ-ACK information (HARQ-ACK information)

HARQ-ACK information may also be referred to as HARQ information. It can be divided into downlink HARQ information and uplink HARQ information. In the current technology, the downlink HARQ-ACK information can indicate the feedback information for the downlink data (such as the physical downlink share channel (PDSCH)), for example, it can be an acknowledgement (ACK) or a negative acknowledgement (negative acknowledgment, NACK) . Uplink HARQ-ACK information may indicate feedback information for uplink data (such as physical uplink share channel (PUSCH)), which is similar to downlink HARQ-ACK information, and may also be ACK or NACK. Among them, ACK may indicate that the data was successfully received and the data was successfully decoded; NACK may indicate that the data was not successfully received or the data was not successfully decoded. The sending device (such as a network device that performs downlink transmission or a terminal device that performs uplink transmission) may perform data retransmission based on the NACK fed back by the receiving device.

In a possible design, the HARQ-ACK information can be an information bit. When the information bit is set to "0", it can indicate NACK, and when the information bit is set to "1", it can indicate ACK; or, when the information When the bit is set to "1", it can indicate NACK, and when the information bit is set to "0", it can indicate ACK, which is not limited in this application.

In some embodiments below, the feedback information is HARQ information as an example to illustrate the embodiments of this application, but this should not constitute any limitation to this application. This application does not exclude the application of the method provided in this application to other scenarios of feedback information.

The following HARQ-ACK information is taken as an example. The downlink HARQ-ACK information may be transmitted through a physical uplink control channel (PUCCH), and may belong to one of uplink control information (UCI). The downlink data of HARQ-ACK information that needs to be fed back may include, for example: PDSCH with a corresponding physical downlink control channel (PDCCH), PDSCH transmission for downlink semi-persistent scheduling (SPS) activation The PDCCH used to indicate downlink SPS release information (there is no data PDSCH at this time) can also be referred to as SPS PDSCH release or SPS PDSCH without corresponding PDCCH. The embodiments of this application do not limit this.

In some embodiments below, for ease of understanding, the following HARQ information is the feedback information for PDSCH as an example for exemplification. There is corresponding ACK and NACK information for each PDSCH, and the ACK and NACK information of at least one PDSCH may correspond to one or more HARQ-ACK information. The specific implementation manner is not limited in this application.

3. Time-frequency resources

In the embodiments of the present application, data or information may be carried by time-frequency resources, where the time-frequency resources may include resources in the time domain and resources in the frequency domain. Wherein, in the time domain, the time-frequency resource may include one or more time domain units (or, it may also be referred to as a time unit), and in the frequency domain, the time-frequency resource may include one or more frequency domain units.

Among them, a time domain unit can be a symbol, or a mini-slot, or a slot, or a subframe, where the duration of a subframe in the time domain It can be 1 millisecond (ms). A slot consists of 7 or 14 symbols. A mini slot can include at least one symbol (for example, 2 symbols or 4 symbols or 7 symbols or 14 symbols, or other Any number of symbols less than or equal to 14 symbols). The above-mentioned time-domain unit sizes are only for the convenience of understanding the solutions of this application, and should not be understood as limiting the application. It is understandable that the above-mentioned time-domain unit sizes can be other values, which are not limited in this application.

A frequency domain unit can be a resource block (resource block, RB), or a resource block group (resource block group, RBG), or a predefined subband (subband), or a precoding resource block group (precoding resource block group). block group, PRG), or a bandwidth part (BWP), or a carrier, or a serving cell.

In the embodiments of the present application, "data" or "information" can be understood as bits generated after information blocks are coded, or "data" or "information" can also be understood as modulation symbols generated after information blocks are coded and modulated.

4. Data processing flow

Taking the following line transmission as an example, the data processing flow may include the network device sending data to the terminal device, the terminal device receiving the data, and processing the received data, and the terminal device feeding back response information to the network device according to the processing result.

It should be understood that, in the embodiment of the present application, processing data, such as processing PDSCH, may include processing such as demodulating and decoding the PDSCH.

In order to allow the terminal device to perform reasonable feedback, the network device generally specifies the feedback time to the terminal device. For example, the network device may carry indication information in the downlink control information (DCI). The indication information indicates the time from receiving the PDSCH to the HARQ feedback of the terminal device, or the network device may notify the terminal device from the The time from receiving PDSCH to HARQ feedback. In this way, the terminal device knows which time unit to perform feedback after receiving the PDSCH.

It should be understood that the foregoing is only an exemplary description for ease of understanding, and the embodiment of the present application does not limit the specific processing flow of data.

5. Downlink data processing time

Generally, in order to ensure that the terminal device can generate a valid (valid) HARQ-ACK information, the first symbol (or start position) of the PUCCH carrying HARQ-ACK information can be after the end of the PDSCH after the downlink data processing time has elapsed. The feedback is performed in the next time unit, or it can be later than the next time unit after the downlink data processing time after the end of the PDSCH. The time unit may be a symbol that can be used for uplink transmission, and it may also include a cyclic prefix (CP) time.

For ease of understanding, description is given in conjunction with FIG. 2.

As shown in Fig. 2, for distinction, K0 is used to represent the time interval between the PDCCH and the PDSCH scheduled by the PDCCH. The time unit of K0 may be, for example, a slot, and the range of K0 may be, for example, K0∈{0 ,32}; Use K1 to represent the HARQ feedback time of the terminal equipment; use T _{proc,1 to} represent the downlink data processing time. It should be understood that the time unit of K0 may also be a symbol or the like.

After receiving the PDSCH, the terminal device starts processing the PDSCH, for example, demodulates and decodes the PDSCH. The PDSCH carries data that needs to be answered or needs to be fed back. The terminal device feeds back HARQ information to the network device at K1 according to the instruction of K1. The HARQ information may be transmitted through the PUCCH, and the PUCCH may be determined according to the indication of K1, the resource indication of the PUCCH, the timing advance (TA), and the like. The first time unit of PUCCH determined by K1 (such as the first time slot or the first symbol, etc.), no earlier than the last time unit of PDSCH (such as the last time slot or the last symbol) after T _proc, the next unit of time after ₁ time (the next time slot or the next symbol, etc.).

The downlink data processing time can be determined according to parameters such as the processing time capability of the terminal device, the time adjustment amount, and the sampling time, for example.

For example, the network device may determine the downlink data processing time T _proc,1 according to the following formula ₁ .

T _proc,1 = (N1+d _1,1 )(2048+144)*k*2 ^-μ *Tc Formula 1

Among them, N1 may be determined by the network device according to the capability information reported by the terminal device. The capability information, for example, may be referred to as the processing time capability of the terminal device. Exemplarily, the capability information reported by the terminal device may have a corresponding relationship with configuration parameters (numerology).

Generally, in the prior art, the terminal device can support capability 1 or capability 2. In other words, the capability information reported by the terminal device indicates that the terminal device supports capability 1 or capability 2.

It should be understood that under some specific configurations, the value of N1 corresponding to capability 1 and the value of N1 corresponding to capability 2 may be defined in the protocol.

For example, when the capability information reported by the terminal device indicates the support capability 1, for a certain numerology and some other transmission conditions, N1 is a fixed value. As shown in Table 1, Table 1 shows the data processing time corresponding to different numerologies under capability 1 in an existing protocol, that is, the PDSCH processing time N1.

For another example, when the capability information reported by the terminal device indicates the support capability 2, for a certain numerology and some other transmission conditions, N1 is a fixed value. As shown in Table 2, Table 2 shows the data processing time corresponding to different numerologies under capability 2 in an existing protocol, that is, the PDSCH processing time N1.

among them:

dmrs-AdditionalPosition indicates the position of additional demodulation reference signal.

dmrs-AdditionalPosition=pos0, indicating that dmrs-AdditionalPosition is at the first symbol, dmrs-AdditionalPosition≠pos0, indicating that dmrs-AdditionalPosition is not at the first symbol.

dmrs-DownlinkForPDSCH-MappingTypeA indicates that the mapping type of the DMRS used to demodulate the PDSCH is A, or dmrs-DownlinkForPDSCH-MappingTypeB indicates that the mapping type of the DMRS used to demodulate the PDSCH is B.

dmrs-AdditionalPosition=pos0in DMRS-DownlinkConfig in both of dmrs-DownlinkForPDSCH-MappingTypeA, dmrs-DownlinkForPDSCH-MappingTypeB, which means: in the downlink DMRS configuration, the DMRS used to demodulate the PDSCH with the mapping type of TypeA and the DMRS used to demodulate the PDSCH with the mapping type of TypeB are TypeB The DMRS used to demodulate the PDSCH, the position of the additional demodulation reference signal is in the first symbol.

dmrs-AdditionalPosition≠pos0in DMRS-DownlinkConfig in either of dmrs-DownlinkForPDSCH-MappingTypeA, dmrs-DownlinkForPDSCH-MappingTypeB or if the higher layer parameter is not configured, it means: in the downlink DMRS configuration, for the demodulation type of TypeA For the DMRS of the PDSCH, the DMRS used to demodulate the PDSCH whose mapping type is TypeB, or the DMRS that is not configured with high-level parameters, the position of the additional demodulation reference signal is not in the first symbol.

N _{1,0 in} Table 1 represents a value determined by another condition, or can also be understood as a value determined by taking into account other conditions or other parameters.

Frequency range 1 (frequency range 1), generally indicates the low frequency band.

Table 1

Table 2

μ means numerology. For example, a value of 0 means 15KHz sub-carrier spacing, a value of 1 means 30KHz sub-carrier spacing, a value of 2 means 60KHz sub-carrier spacing, and a value of 3 It shows the 120KHz sub-carrier spacing.

It can be seen that for the case where the numerology is 15KHz subcarrier spacing, when the capability information reported by the terminal device indicates support capability 1, it means that it can support data processing time of 8 symbols (under a specific DMRS configuration); when the terminal device When reporting its capability as capability 2, it means that it can support data processing time of 3 symbols. In this case, for a terminal device that indicates that the reported capability information indicates that it supports capability 1, if the network device schedules data and instructs to feed back resources, ensure that the feedback time meets the 8-symbol processing time, otherwise (for example, the network device indicates The feedback resource is for the terminal device to feed back 4 symbols after the PDSCH), the terminal device cannot provide an effective and usable HARQ-ACK feedback information.

numerology is a new concept introduced in NR, which can be understood as a set of parameters used in communication systems, such as subcarrier spacing (SCS), symbol length, CP length, and resource block (RB) Number, slot length, frame format, etc. A cell can support one or more numerology, such as numerology for uplink transmission, numerology for downlink transmission, and so on.

It should be understood that the specific content contained in the numerology listed here is only an exemplary description, and should not constitute any limitation on this application. For example, numerology may also include other granular parameters that can be supported in NR.

Taking the subcarrier interval as an example, N1 corresponding to different subcarrier intervals may have different values. Specifically, you can refer to the existing agreement, which will not be repeated here.

In addition, numerology may include the numerology of PDCCH, for example, denoted as μPDCCH. The numerology may also include the numerology of PDSCH, for example, it is denoted as μPDSCH. The numerology can also include the numerology of uplink transmission, such as μUL.

According to different numerology, N1 can be a different value, so when the network device determines T _proc,1 , it can be determined according to the largest value. For example, N1 corresponding to μPDCCH, N1 corresponding to μPDSCH, and N1 corresponding to μUL are different. According to N1 corresponding to μPDCCH, N1 corresponding to μPDSCH, and N1 corresponding to μUL, the network device may obtain three values of T _proc,1 , Then the T _proc,1 finally determined by the network device can be the maximum value of the three T _proc,1 values. That is to say, if the processing time caused by the different numerology of each channel is different, the network device can use the maximum time as the downlink data processing time to ensure that sufficient time is reserved for the terminal device.

In the above formula 1, k represents a constant, for example, it can be the ratio of the maximum sampling time of the signal of the entire system to the minimum sampling time of the signal of the entire system.

Wherein, T _C represents a time unit. For example, in the current protocol, T _C =1/(Δf _max *N _f ), Δf _max =480.10 ³ Hz, and N _f =4096.

Among them, d _{1,1 is} related to PDSCH resource mapping. It can be called the time adjustment amount. Specifically, d _1,1 can be related to the resource mapping type of PDSCH, the duration of PDSCH (for example, occupying 2, 4, and 7 symbol lengths), the resources of PDSCH mapping, the mapping position of DMRS in PDSCH, the resource relationship of PDCCH mapping, etc. related. For example, when the PDSCH mapping type is mapping type A (mapping type A), and the last symbol i<7 of the PDSCH, d _1,1 =7-i, otherwise d _1,1 = 0.

It should be understood that the meaning of each of the foregoing parameters can refer to the existing protocol, which is not limited in the embodiment of the present application.

Generally, when the network device indicates the HARQ feedback time for the terminal device, the terminal device needs to report capability information. When the terminal device reports the capability information, it may take into consideration: channel estimation time based on demodulation reference signal (DMRS), processing time of the terminal device, and so on.

It should be understood that the processing time of the terminal device, for example, may include: the time for processing the PDSCH according to the estimated channel, the time for generating HARQ-ACK information according to the processing result, and so on.

Under multi-station transmission, such as coordinated multiple point (CoMP) transmission, the terminal device may have different processing methods for multiple received data. Then if the network device performs the terminal device according to the design of the prior art The allocation of PUCCH resources may cause the terminal equipment to fail to form a valid HARQ-ACK message, or the network equipment may allocate a relatively long feedback time considering the worst case caused by multiple stations, which will increase the feedback delay and affect System performance.

In view of this, the present application provides a communication method, so that network equipment can reasonably allocate feedback resources to terminal equipment and improve resource utilization.

The various embodiments provided in this application will be described in detail below with reference to the accompanying drawings.

FIG. 3 is a schematic interaction diagram of a communication method 300 provided by an embodiment of the present application, shown from the perspective of device interaction. As shown in the figure, the method 300 may include the following steps.

310. The terminal device generates capability information based on the transmission information of the multiple data.

The transmission information of multiple data can indicate information related to the transmission of multiple data. For example, multiple network devices, such as multiple TRPs, send multiple data transmission information to the terminal device. One network device can also send multiple data transmission information of multiple network devices to the terminal device. No restrictions. The data may be various types of data. For example, the data may be PDSCH. That is, in step 310, the terminal device generates capability information based on the transmission information of multiple PDSCHs. It should be understood that the "data" in the embodiments of the present application may be replaced with "PDSCH".

Optionally, the transmission information of multiple data may include one or more of the following information: transmission time of each data, overlapping time of multiple data, start time, interval between start times, end time, The interval between the end time, the timing deviation of the TRP of the sending and receiving point, the configuration parameters of multiple data, the configuration parameters of DMRD, the configuration parameters of PDCCH, or the processing method of multiple PDSCHs, etc.

Among them, the transmission time of each data is used to indicate the transmission time length of each data, or in other words, the transmission time of the transmission data.

Wherein, the overlap time of multiple data is used to indicate the length of time that multiple data time domain resources are repeated, or in other words, the time length of time domain resources used to transmit multiple data overlap.

Wherein, the starting time indicates: the starting position of the transmission resource for transmitting data (that is, the PDSCH) in the time domain. That is, it represents the starting position in the time domain of transmission resources related to part or all of the PDSCHs in the multiple PDSCHs. For example, the start time indicates the start position of each data transmission resource in the time domain.

Wherein, the end time indicates: the end position of the transmission resource for transmitting data (that is, the PDSCH) in the time domain. That is, it indicates the end position in the time domain of the transmission resources related to some or all of the PDSCHs in the multiple PDSCHs. For example, the end time indicates the end position of each data transmission resource in the time domain.

Wherein, the configuration parameters of the data may include, for example, the mapping type of the data, for example, the mapping type of the PDSCH is type A or type B.

Among them, the configuration parameters of the DMRS may include, for example, one or more of the following: the symbol position of the pre-DMRS, the number of symbols of the pre-DMRS, the symbol position of the additional (or post) DMRS, and the symbol position of the additional (or post) DMRS Number, DMRS configuration type (for example, DMRS configuration type is type 1 or DMRS configuration type is type 2), or code division orthogonal group information where DMRS is located, etc.

Wherein, the configuration parameters of the PDCCH may include, for example, one or more of the following: the control resource group or search space set where the PDCCH is located, the time domain resource information where the PDCCH is located, the detection period of the PDCCH detection, the detection pattern, or the detection time domain offset Shift and other information. The information of the control resource group, for example, may include information about the number of symbols occupied by the control resource group.

Among them, the processing method of multiple PDSCHs can also be referred to as the demodulation hypothesis of PDSCH, which means how the terminal equipment will process multiple PDSCHs. Specific processing methods may include, for example, separate processing, joint processing, and cross processing. These three processing methods are described in detail below. The capability information of a terminal device can be associated with multiple PDSCH processing modes. It can also be understood that the capability information reported by the terminal device can correspond to the way the terminal device processes multiple data, or it can also be understood as the terminal device reporting The capability information of is reported based on how the terminal device processes multiple data. Specifically, you can refer to the association method 1 below.

The following details the above-mentioned information and how the terminal device generates capability information based on the transmission information of multiple data.

In the embodiments of this application, considering that in some scenarios, such as multi-station transmission, the terminal device may have different processing methods or feedback methods for the multiple data to be received, so it is proposed that the transmission information reporting capability information based on multiple data .

The capability information includes at least the following two possible designs.

Design 1. Capability information can be understood as the capability information of a terminal device under multi-station transmission, or the processing time capability of a terminal device under multi-station transmission.

Design 2. Capability information is the capability information of terminal equipment under single-site transmission.

The following example first introduces the scheme of Design 1.

Generating capability information based on the transmission information of multiple data can also be understood as that the capability information reported by the terminal device is associated with the transmission of multiple data, or it can also be understood as the capability information reported by the terminal device is associated with multi-station transmission Or, it can also be understood that the capability information reported by the terminal device is related to the manner in which the terminal device processes multiple data, and/or the capability information reported by the terminal device is related to the feedback manner of the terminal device for multiple data.

Optionally, the capability information mentioned in Design 1 may represent capability information indicating that the terminal device supports capability 3, which is different from the existing capability 1 and capability 2, that is, the capability 3 represents the capability under multi-station transmission. Capability 3 can correspond to one or more capabilities, and the protocol can predefine the value of the PDSCH processing time corresponding to these capabilities (for example, in a form similar to Table 1 or Table 2).

The terminal equipment reports appropriate capability information according to the transmission information of multiple data (or information transmitted by multiple stations). The network equipment reads the capability information and the value of the PDSCH processing time corresponding to the capability information, thereby knowing the PDSCH processing time under the corresponding transmission configuration. Here, different capabilities can correspond to different transmission configurations. There is no restriction on this.

Optionally, the capability information reported by the terminal device can be associated with the transmission of multiple data through one or more of the following association methods.

Association method 1: The capability information reported by the terminal device is associated with the way the terminal device processes multiple data. It can also be understood that the capability information reported by the terminal device can correspond to the way the terminal device processes multiple data, or, It is understood that the capability information reported by the terminal device is reported based on the processing manner in which the terminal device processes multiple data.

The association mode 1 may be pre-defined, for example, pre-defined by the protocol, or pre-configured by the network device, which is not limited.

The embodiment of the present application does not limit the specific form of the association method 1. For example, the association method 1 may be in the form of a table. as shown in Table 3.

table 3

处理方式Processing method	N1 N1

处理方式1Treatment method 1	N1_值aN1_value a
处理方式2 Treatment 2	N1_值b N1_value b

处理方式3Treatment 3	N1_值cN1_value c
……...	……...

N1_value a, N1_value b, N1_value c are integers.

Among them, processing method 1, processing method 2, processing method 3, ..., are used to indicate different processing methods; N1_value a, N1_value b, N1_value c, ..., indicate the corresponding processing methods The value of N1.

When the terminal device reports the capability information, it can determine the processing mode based on the transmission information of multiple data, and report based on the processing mode.

Optionally, the terminal device can also report the processing mode. Taking the data as the PDSCH as an example, the terminal device can separately report the processing mode of the terminal device on the PDSCH.

For example, when the terminal device is configured with two sets of PDCCH configuration parameters, for example, the terminal device is configured with two sets of control resource groups (CORESET) (that is, the two sets of CORESET group IDs are different), the terminal device is demodulating a PDSCH Whether to use the information in other PDCCHs (PDCCHs that do not schedule this PDSCH).

For example, suppose that the configuration parameters of the two sets of PDCCH are respectively denoted as PDCCH configuration parameter 1 and PDCCH configuration parameter 2, PDCCH configuration parameter 1 corresponds to PDSCH1 and PDCCH configuration parameter 2 corresponds to PDSCH2. Then, the terminal device can separately report the PDSCH processing mode of the terminal device, such as whether the terminal device uses the information in the configuration parameter 2 of the PDCCH when demodulating PDSCH1; or, when the terminal device demodulates PDSCH2, whether Use the information in PDCCH configuration parameter 1.

In another example, when a terminal device demodulates a PDSCH scheduled by a PDCCH identified by a certain CORESET group, does it use scheduling information in a PDCCH identified by another CORESET group. Among them, the scheduling information may include, but is not limited to, for example, the DMRS port identifier used by the scheduled PDSCH, the rate matching resource element (RE) of the DMRS (for example, Code Division Multiple (Code Division Multiple, CDM) that requires rate matching for PDSCH). ) Number of groups), the length of the time domain symbol occupied by the scheduled PDSCH, the start symbol position of the scheduled PDSCH, the end symbol position of the scheduled PDSCH, the zero-power channel state information reference signal (Channel State Information-Reference Signal, CSI) -RS) (Zero power CSI-RS, ZP CSI-RS) indication information, rate matching resource indication, HARQ process indication, etc.

For example, suppose that the two groups of CORESET group IDs are marked as CORESET group ID 1, CORESET group ID 2, and the PDCCH of CORESET group ID 1 corresponds to PDSCH1 (or the PDCCH of CORESET group ID 1 is used to schedule PDSCH 1), and the PDCCH of CORESET group ID 2 Corresponding to PDSCH2 (or the PDCCH of CORESET group identifier 2 is used to schedule PDSCH2). Then, the terminal device can separately report the PDSCH processing mode of the terminal device, such as whether the terminal device uses the scheduling information in the PDCCH of the CORESET group ID 2 when demodulating PDSCH1; or, when the terminal device demodulates PDSCH2 , Whether to use the scheduling information in the PDCCH of the CORESET group ID 1.

Association 2: The capability information reported by the terminal device is associated with the feedback mode of the terminal device for multiple data. It can also be understood that the capability information reported by the terminal device may correspond to the feedback mode of the terminal device for multiple data, or, It can also be understood that the capability information reported by the terminal device is reported based on the feedback mode of the terminal device for multiple data.

The association mode 2 may be pre-defined by the protocol, or pre-configured by the network device, which is not limited.

The embodiment of the present application does not limit the specific form of the association method 2. For example, the association method 2 may be in the form of a table. As shown in Table 4.

N1_value d, N1_value e, and N1_value f are integers.

Among them, feedback method 1, feedback method 2, feedback method 3, ... are used to indicate different feedback methods; N1_value d, N1_value e, N1_value f, ..., indicate the corresponding feedback methods N1.

When a terminal device reports capability information, it may determine a feedback mode based on the transmission information of multiple data, and report based on the feedback mode.

Table 4

反馈方式2Feedback method 2	N1_值eN1_value e

反馈方式3Feedback method 3	N1_值fN1_value f
……...	……...

It should be understood that N1_value d, N1_value e, N1_value f,... in Table 4 are the same as N1_value a, N1_value b, N1_value c,..., N1 in Table 3 It can be the same or different, or the N1_value d, N1_value e, N1_value f,... in Table 4 are the same as N1_value a, N1_value b, N1_value c in Table 3. ……, N1 can be associated or independent, which is not limited.

It should also be understood that the foregoing Table 3 and Table 4 are only exemplary descriptions, and the application is not limited thereto. For example, the "processing method" in Table 3 and the "feedback method" in Table 4 can be expressed in other terms.

It should be understood that the above two association methods can be used independently or in combination, which is not limited. This is described in detail below in conjunction with step 320.

Optionally, the manner in which the terminal device processes multiple data includes at least the following three.

Processing method 1, separate processing;

Treatment method 2, joint treatment;

Processing method 3, cross processing.

It should be understood that, in the embodiment of the present application, the processing of the data by the terminal device may include, for example, processing such as demodulating and decoding the data, which is not limited.

In the following, the three processing methods will be described in detail in conjunction with the corresponding steps, and will not be repeated here.

In other words, under multi-station transmission, the terminal device can process the received data from multiple network devices (for example, multiple TRPs) through any of the foregoing processing methods.

In the following embodiments, for brevity, the manner in which the terminal device processes multiple data is recorded as the processing manner.

The above several processing methods are described in detail below.

Optionally, the terminal device may send feedback information for multiple pieces of data to the network device in any of the following ways.

Feedback method 1: separate feedback.

In other words, the terminal device separately feeds back multiple received data, in other words, the feedback of each data is relatively independent.

For example, take the terminal device receiving PDSCH1 and PDSCH2 as an example.

For the network equipment, the network equipment allocates resources for feeding back the PDSCH 1 and resources for feeding back the PDSCH 2 for the terminal devices.

For the terminal device, after receiving the PDSCH 1, the terminal device performs feedback based on the resources allocated by the network device for feeding back the PDSCH 1; after receiving the PDSCH 2, the terminal device performs feedback based on the resources allocated by the network device for feeding back the PDSCH 2.

Feedback method 2: Joint feedback.

That is, after determining the feedback information of all data, the terminal device feeds back the feedback information of the multiple data.

For network equipment, the network equipment allocates resources for PDSCH feedback and feedback for terminal equipment

PDSCH 2 resources, and when allocating feedback resources, consider that the terminal device will receive another PDSCH after receiving one PDSCH.

For the terminal device, after receiving the PDSCH 1 and PDSCH 2, the terminal device determines the feedback information for PDSCH 1 and the feedback information for PDSCH 2, and then based on the resources allocated by the network device for feedback of PDSCH 1 and for feedback of PDSCH 2 The feedback information corresponding to PDSCH 1 and the corresponding feedback information of PDSCH 2 are fed back together. The feedback information can be in one signaling or two signaling, which is not limited.

Feedback mode 2 may indicate a mode in which multiple feedback information can be fed back together. In this mode, multiple feedback information may include uplink control information, specifically, HARQ-ACK information, channel state information, etc. Multiple feedback information can be fed back together, which may mean that multiple feedback information is fed back in one channel (such as PUCCH). Multiple feedback messages can be independently coded or jointly coded. Joint coding means that multiple feedback messages are coded together.

Optionally, the terminal device can also report the feedback mode. The terminal device reports its support: joint feedback and/or separate feedback.

In an example, N bits of information are used to identify the feedback mode, where each bit corresponds to a feedback mode, and N is an integer greater than or equal to 1, for example, N is 2. For example, the value of each bit can be used to indicate whether it supports the feedback mode of the bit to one. When a bit takes a specific value (such as 1), it means that the corresponding feedback method is supported; when a bit takes a value of other specific values (such as 0), it means that the corresponding feedback method is not supported. If the reported information is a specific value, such as all 0s, it means that the terminal device supports a certain default feedback mode, such as feedback in different time units (such as time slots).

In another example, a value of the feedback information corresponds to a combination of one or more feedback methods. It is assumed that the feedback information can take: a first value, a second value, and a third value. For example, the first value is 01, the second value is 10, and the third value is 00. If the feedback information takes the first value, it means that the terminal device supports feedback mode 1; if the feedback information takes the second value, it means that the terminal device supports feedback mode 2; if the feedback information takes the third value, it means that the terminal device supports feedback mode 1 and feedback mode. 2. It should be understood that the values of the first value, the second value, and the third value and the corresponding feedback manner are only an example, which does not limit the protection scope of the embodiments of the present application.

In another example, the terminal device reports whether it supports a certain feedback method, and the feedback method not reported indicates that it supports it by default. For example, if the terminal device reports that it does not support feedback mode 1, then the terminal device can default to support feedback mode 2.

In the following embodiments, for brevity, the feedback mode of the terminal device for multiple data is recorded as the feedback mode.

It should be understood that the foregoing feedback manner is only an exemplary description, and the embodiment of the present application is not limited thereto. For example, the terminal device can also feed back part of the feedback information together. For example, in the HARQ-ACK information corresponding to multiple PDSCHs, part of the HARQ-ACK information can be fed back together, and the remaining HARQ-ACK information and this part of HARQ-ACK information are fed back separately.

Optionally, before step 310, the method may further include: the network device may instruct the terminal device to report a feedback manner for multiple data. For example, the network device may instruct the terminal device to report whether to perform joint feedback of multiple data.

Optionally, before step 310, the method may further include: the network device instructs the terminal device to report capability information. The terminal device reports the capability information after receiving the instructions from the network device, thereby saving unnecessary signaling overhead.

320: The terminal device sends capability information. Correspondingly, the network device receives the capability information.

The capability information is used for the resource configuration of the terminal device, and the resource is used for the feedback of the terminal device to multiple PDSCHs. Or, it can also be understood that the network device configures the feedback resource for the terminal device based on the capability information, that is, the terminal device configuration It is a feedback resource for feeding back multiple PDSCHs. For example, after the network device receives the capability information, it can determine the downlink data processing time T _proc,1 for the terminal device based on the information associated with the capability information.

The following is an illustrative description in combination with three cases.

Case 1, the capability information sent by the terminal device is associated with the processing mode of the terminal device to process multiple data (that is, the above-mentioned association mode 1).

In this case, the network device determines the value of N1 according to the processing method associated with the received capability information in combination with Table 3, and then uses the formula 1 described above to determine the downlink data processing time T _proc for the terminal device _,1 , the form and content of Table 3 and Formula 1 are only examples, this application is not limited to this, the following are similar, and will not be repeated.

For example, the capability information sent by the terminal device is associated with processing method 1, combined with Table 3, the network device determines that the value of N1 is N1_value a, and substituting N1_value a into the above-mentioned formula 1, the network device can determine for the terminal device Outgoing downstream data processing time T _proc,1 .

Case 2: The capability information sent by the terminal device is associated with the feedback mode of the terminal device for multiple data (that is, the above-mentioned association mode 2).

In this case, the network device determines the value of N1 according to the feedback mode associated with the received capability information in combination with Table 4, and then uses the formula 1 described above to determine the downlink data processing time T _proc for the terminal device _,1 , the form and content of Table 4 and Formula 1 are only examples, and this application is not limited to this, and it is similar in the following and will not be repeated.

For example, the capability information sent by the terminal device is associated with the feedback method 2, combined with Table 4, the network device determines that the value of N1 is N1_value e, and substituting the N1_value e into the above-mentioned formula 1, the network device can determine for the terminal device Outgoing downstream data processing time T _proc,1 .

Case 3: The capability information sent by the terminal device is associated with the processing method of the terminal device to process multiple data and the terminal device's feedback method for multiple data (ie, the above-mentioned association method 1 and association method 2 are used in combination).

In this case, the network device determines the value of N1 according to the processing method and feedback method associated with the received capability information, and combines Table 3 and Table 4, and then determines the value of N1 for the terminal device through the formula 1 described above Downstream data processing time T _proc,1 .

For example, the capability information sent by the terminal device is associated with processing method 2 and feedback method 1, combined with Tables 3 and 4, the network device determines two values of N1 for the terminal device, namely N1_value b and N1_value d.

In a possible implementation, the network device substitutes the N1_value b and N1_value d into the above-mentioned formula 1, and may obtain two different downlink data processing times T _proc,1 , and the network device selects two T _proc,1 with a larger value in T _{proc,1 is} used as the downlink data processing time of the terminal device.

In another possible implementation manner, the network device substitutes the N1_ value b and N1_ value d into the above-mentioned formula 1, and may obtain two different downlink data processing times T _proc,1 , and the network device selects two T _{proc, 1} with the smaller value of T _{proc, 1 is} used as the downlink data processing time of the terminal device.

In another possible implementation manner, the network device selects the larger value of N1_value b and N1_value d as the N1 value, and substitutes the N1 value into the above-mentioned formula 1, and the network device may be a terminal device Determine a downstream data processing time T _proc,1 .

In another possible implementation manner, the network device selects the smaller of N1_value b and N1_value d as the N1 value, and substitutes the N1 value into the above-mentioned formula 1, and the network device may be a terminal device Determine a downstream data processing time T _proc,1 .

In another possible implementation manner, the network device selects any one of N1_value b and N1_value d as the N1 value, and substitutes the N1 value into the above-mentioned formula 1, and the network device can determine for the terminal device A downstream data processing time T _{proc,1 is given} .

It should be understood that the above example uses the network device to determine the downlink data processing time for the terminal device based on Formula 1 as an example. The embodiment of the application is not limited to this. For example, the network device may be based on other formulas (such as a modification of Formula 1). Formula) determines the downlink data processing time for the terminal equipment.

It should also be understood that when the network device determines the downlink data processing time for the terminal device, it may also refer to other parameters for determination, which is not limited.

Optionally, the network device may notify the terminal device of the determined downlink data processing time. For example, the network equipment may carry indication information in the downlink control information, and the indication information indicates the time from receiving the PDSCH to the HARQ feedback of the terminal equipment. In this way, the terminal device knows which time unit to perform feedback after receiving the PDSCH.

330. The network device configures a resource for the terminal device based on the capability information, and the resource is used for the terminal device to feedback multiple pieces of data.

In other words, the network device determines the downlink data processing time for the terminal device based on the capability information reported by the terminal device, and determines the feedback resource for the terminal device, so that the terminal device can perform feedback based on the allocated feedback resource after receiving the data.

The following describes in detail the way the terminal device processes multiple data.

Considering that when a terminal device receives multiple data, for example, in a multi-station transmission scenario, different processing methods may be adopted. Therefore, the embodiment of the present application proposes that the terminal device generates capability information based on the transmission information of multiple data and reports it to the network device so that the network device can allocate reasonable feedback resources to the terminal device based on the capability information.

To facilitate understanding, first introduce the location of PDSCH time domain resource mapping.

The mapping mode of PDSCH in the time domain can include a first mapping mode and a second mapping mode. The first mapping mode can be mapping type A (mapping type A) in the NR protocol, and the second mapping mode can be the NR protocol. Mapping type B (mapping type A), mapping type A and mapping type B respectively correspond to different resource mapping restrictions. Under normal circumstances, the network device can indicate the PDSCH mapping manner to the terminal device through high-level signaling. For example, the network device may indicate the PDSCH mapping manner to the terminal device through radio resource control (RRC) signaling.

Taking the PDSCH mapping type as the mapping type A as an example, the end symbol (that is, the last symbol) of the PDSCH is marked as i, when i<7, d _1,1 = 7-i, otherwise d _{1, 1} = 0. In other words, the end symbols of PDSCH are different, d _1,1 may also be different. It can be seen from the above formula 1 that if d _{1,1 are} different, the downlink data processing time T _{proc,1 of the} terminal device may also be different.

For example, as shown in FIG. 4, the PDSCH mapping type is mapping type A. In the cases (1)-(6) listed in FIG. 4, the end symbols of the PDSCH are all different. In (1)-(3) in Fig. 4, i<7, so d _1,1 = 7-i; in (4)-(6) in Fig. 4, i>7, so d _1,1 = 0.

In the scenario of multi-station transmission, the terminal device may be scheduled by multiple network devices, and the scheduling between multiple network devices may be related to a certain degree, or may be independent. For example, the scheduled PDSCH may be any one or more of (1)-(6) in FIG. 4. In addition, within a time unit, the location of the time domain resource mapping of multiple PDSCHs received by the terminal device in a time unit may be different.

Therefore, based on the different locations of the time domain resource mapping of multiple PDSCHs, the terminal equipment may have different processing methods.

In the following, two network devices (for example, two TRPs) sending data to a terminal device are taken as an example to illustrate how the terminal device processes multiple data.

In order to distinguish, the two network devices are marked as network device 1 and network device 2, respectively, and the PDSCH from network device 1 is recorded as PDSCH 1, and the PDSCH from network device 2 is recorded as PDSCH 2.

Processing method 1, separate processing.

In other words, the terminal device will process PDSCH 1 and PDSCH 2 separately, for example, the terminal device processes PDSCH 1 and PDSCH 2 separately, and the information processed by the two PDSCHs is not exchanged, for example, it can be completely decoded independently.

When the terminal device adopts processing method 1, for PDSCH 1 and PDSCH 2, the allocation of feedback resources only needs to satisfy the processing time of each PDSCH. That is to say, in this processing manner, the network device can allocate resources for feeding back the PDSCH 1 and resources for feeding back the PDSCH 2 to the terminal device respectively.

When the terminal device adopts the processing method 1, the feedback method of separate feedback (that is, the feedback method 1) can be adopted.

As shown in Figure 5. Figure 5 shows a situation where the terminal device receives the PDSCH (PDSCH 1 or PDSCH 2) and feeds back HARQ.

Optionally, when the terminal device reports the capability information, it may separately report the capability information corresponding to downlink processing (that is, processing PDSCH) and the capability information corresponding to uplink processing (feedback HARQ uplink channel processing).

In other words, when the network device determines the downlink data processing time for the terminal device, it will consider the processing time of the terminal device, for example, including the processing time of the PDSCH and the processing time of the uplink channel of the HARQ feedback. To distinguish, the processing time of PDSCH is recorded as N _DL , and the processing time of uplink channel of feedback HARQ is recorded as N _UL .

In FIG. 5, the network device may determine the downlink data processing time T _proc,1 for the terminal device to feed back the PDSCH according to the following formula 2.

T _proc,1 =(N _DL +N _UL +d _1,1 )(2048+144)*k*2 ^-μ *Tc. Formula 2

The terminal device may feed back HARQ to the network device based on the downlink data processing time T _proc,1 .

It should be understood that FIG. 5 is only an exemplary illustration, and the present application is not limited thereto. For example, a network device may also use an existing method to allocate resources for feeding back PDSCH to a terminal device.

Treatment method 2, joint treatment.

That is to say, after the terminal equipment and other PDSCH 1 and PDSCH 2 are completely received, joint processing (such as joint coding, etc.) is performed, such as mutual use of the information of another PDSCH, such as interference cancellation.

Joint processing can mean that when the terminal device is configured with two sets of PDCCH configuration parameters, for example, the terminal device is configured with two sets of control resource groups (CORESET) (that is, the two sets of CORESET group IDs are different), the terminal device is demodulating When a PDSCH uses the information in other PDCCHs (the PDCCH that does not schedule this PDSCH). For example, suppose that the configuration parameters of the two sets of PDCCH are respectively denoted as PDCCH configuration parameter 1 and PDCCH configuration parameter 2, PDCCH configuration parameter 1 corresponds to PDSCH1 and PDCCH configuration parameter 2 corresponds to PDSCH2. If the terminal device performs joint processing, it means that the terminal device can use the information in PDCCH configuration parameter 2 when demodulating PDSCH1; or, when the terminal device is demodulating PDSCH2, it can use the information in PDCCH configuration parameter 1. information.

Or, for joint processing, when the terminal device demodulates the PDSCH scheduled by the PDCCH corresponding to a certain CORESET group identifier, the scheduling information in the PDCCH identified by the other CORESET group may be used. Wherein, the scheduling information may include, but is not limited to: the DMRS port identifier used by the scheduled PDSCH, the rate matching RE of the DMRS (for example, the number of CDM groups that the PDSCH needs to rate matching), the length of time domain symbols occupied by the scheduled PDSCH, The start symbol position of the scheduled PDSCH, the end symbol position of the scheduled PDSCH, ZP CSI-RS indication information, rate matching resource indication, HARQ process indication, etc. For example, suppose that the two groups of CORESET group IDs are marked as CORESET group ID 1, CORESET group ID 2, and the PDCCH of CORESET group ID 1 corresponds to PDSCH1 (or the PDCCH of CORESET group ID 1 is used to schedule PDSCH 1), and the PDCCH of CORESET group ID 2 Corresponding to PDSCH2 (or the PDCCH with CORESET group identifier 2 is used to schedule PDSCH2). If the terminal device performs joint processing, it means that the terminal device can use the scheduling information in the PDCCH of the CORESET group ID 2 when demodulating PDSCH1; or, when the terminal device is demodulating PDSCH2, it can use the CORESET group ID 1 Scheduling information in PDCCH.

When the terminal device adopts processing method 2, there is PDSCH interaction in the processing phase, and the allocation of feedback resources needs to consider the interaction time of each PDSCH in the processing phase. That is to say, in this processing mode, the network device will receive another PDSCH based on the terminal device receiving one PDSCH and allocate feedback resources to the terminal device.

When the terminal device adopts processing method 2, the feedback method of joint feedback can be adopted.

As shown in Figure 6. Assume that the terminal device receives PDSCH 1 first.

When the network device determines the downlink data processing time for the terminal device, it will consider the PDSCH processing time N _DL , the HARQ uplink channel processing time N _UL , and the waiting time ΔS for the terminal device to wait to receive PDSCH 2 after receiving PDSCH 1.

In FIG. 6, the network device can determine the downlink data processing time T _proc,1 for feeding back the PDSCH 1 and PDSCH 2 for the terminal device according to the following formula 3.

T _proc,1 =(ΔS+N _DL +N _UL +d _1,1 )(2048+144)*k*2- ^μ *Tc. Formula 3

Among them, N _DL includes the time for the terminal device to process PDSCH 1 and PDSCH 2, and N _UL includes the uplink channel processing time for the terminal device to feedback HARQ 1 (that is, feedback for PDSCH 1) and HARQ 2 (that is, feedback for PDSCH 2).

The terminal device may feed back HARQ 1 to network device 1 and HARQ 2 to network device 2 based on the downlink data processing time T _proc,1 .

Processing method 3, cross processing.

That is to say, the terminal device preferentially processes the information of the PDSCH that is successfully received first, and for the PDSCH that is successfully received later, the processing information (for example, decoding information, etc.) of the PDSCH that is successfully received first may be used in processing.

It should be understood that the cross processing is only a naming for distinction, and does not limit the protection scope of the embodiments of the present application.

When the terminal device adopts the processing method 3, there is PDSCH interaction in the processing phase, and the allocation of feedback resources needs to consider the interaction time of each PDSCH in the processing phase. That is to say, in this processing mode, the network device allocates feedback resources to the terminal device based on the interaction time of the terminal device to process the PDSCH.

When the terminal device adopts processing method 3, the feedback method of separate feedback (as shown in the example diagram in FIG. 5) may be used, or the feedback method of joint feedback (as shown in the example diagram in FIG. 6) may be used.

It should be understood that the foregoing several processing methods are only exemplary descriptions, and the application is not limited thereto.

The following describes in detail the transmission information of the multiple data in step 310, and the terminal device generating capability information based on the transmission information of the multiple data.

When the terminal device generates capability information, it can consider multiple data transmission information. Alternatively, it can also be understood that the terminal device may determine a processing method for processing multiple data based on the transmission information of the multiple data, and report capability information based on the processing method for the multiple data. Alternatively, it can also be understood that the terminal device may determine a feedback manner for multiple data based on the transmission information of the multiple data, and report the capability information based on the multiple data feedback manner.

In the following, the data is taken as the PDSCH, which is illustrated in conjunction with FIG. 4. Assuming that one grid in Figure 4 can represent a time domain symbol, 14 grids are a slot, and the filled grid represents the time domain unit occupied by the PDSCH.

Solution 1: Based on the transmission time of each data, the terminal device generates capability information.

It can also be understood that the terminal device determines the processing mode for processing the data based on the transmission time of each data.

The transmission time of each data is used to indicate the length of transmission time of each data.

For example, assuming that the time domain resource allocation of the PDSCH is the case of (1) in FIG. 4, it is explained that the transmission time length of the PDSCH is 5 symbols in length. For another example, assuming that the time domain resource allocation of the PDSCH is the case of (4) in FIG. 4, it is explained that the transmission time length of the PDSCH is 9 symbols in length.

Illustratively, for example, assuming that the transmission time lengths of PDSCH 1 and PDSCH 2 are both very short, the terminal device may determine that the processing method of processing data is the above processing method 2 or the above processing method 3; for another example, suppose PDSCH 1 and PDSCH 2 If the transmission time length is very long, the terminal device can determine that the processing method for processing the data is the above processing method 1.

It should be understood that the foregoing is only an exemplary description, and this application does not limit how the terminal device selects a processing mode based on Solution 1.

It should also be understood that the terminal device may also select a feedback mode based on scheme 1.

Solution 2: Based on the overlapping time of multiple data, the terminal device generates capability information.

It can also be understood that the terminal device determines the processing mode for processing the data based on the overlapping time of multiple data.

The overlapping time of multiple data is used to indicate the length of time that multiple data time domain resources repeat.

For example, assuming that the time domain resource allocation of PDSCH 1 is the case of (1) in Fig. 4, and the time domain resource allocation of PDSCH 2 is the case of (6) in Fig. 4, it is explained that the PDSCH 1 and PDSCH 2 The overlap time is 5 symbols in length. For another example, assuming that the time domain resource allocation of PDSCH 1 is the case of (1) in Figure 4, and the time domain resource allocation of PDSCH 2 is the case of (2) in Figure 4, then the PDSCH 1 and PDSCH 2 are explained. The overlap time is 4 symbols in length.

Illustratively, for example, assuming that the overlap time of PDSCH 1 and PDSCH 2 is very long, the terminal device may determine that the processing method of processing data is the above processing method 2 or the above processing method 3; for another example, suppose the transmission of PDSCH 1 and PDSCH 2 If the length of time is short, the terminal device can determine that the processing method for processing the data is processing method 1 above.

Illustratively, this scheme can also be used in combination with scheme 1. For example, assuming that the overlap time of PDSCH 1 and PDSCH 2 is very long, and the transmission time lengths of PDSCH 1 and PDSCH 2 are both very short, the terminal device can wait for both PDSCH 1 and PDSCH 2 to be successfully received before performing joint processing.

It should be understood that the foregoing is only an exemplary description, and this application does not limit how the terminal device is based on solution 2 or the terminal device is based on solution 1 and solution 2. How to select a processing mode is not limited.

It should also be understood that the terminal device may also be based on the scheme 2, or the terminal device may select the feedback mode based on the scheme 1 and scheme 2.

Scheme 3, based on the interval between the starting moments, the terminal device generates capability information.

It can also be understood that the terminal device determines the processing mode of processing data based on the interval between the starting moments.

The interval between starting moments is used to indicate the time interval between the starting positions of each data transmission resource in the time domain.

For example, assuming that the time domain resource allocation of PDSCH 1 is the case of (1) in Fig. 4, and the time domain resource allocation of PDSCH 2 is the case of (6) in Fig. 4, it is explained that the PDSCH 1 and PDSCH 2 The interval between the starting moments is 0 symbol length.

Illustratively, for example, assuming that the interval between the start time of PDSCH 1 and PDSCH 2 is very short, the terminal device may determine that the processing method of processing data is any one of the foregoing processing method 2 and processing method 3; for another example, Assuming that the interval between the start time of PDSCH 1 and PDSCH 2 is very long, the terminal device can determine that the processing method for processing data is the above processing method 1.

Illustratively, this scheme can also be used in combination with scheme 1. For example, assuming that the interval between the start time of PDSCH 1 and PDSCH 2 is very short, and the transmission time lengths of PDSCH 1 and PDSCH 2 are both very short, the terminal device can wait for both PDSCH 1 and PDSCH 2 to be successfully received before joint processing. That is, the above processing method 2.

Illustratively, this scheme can also be used in combination with scheme 2. For example, assuming that the interval between the start time of PDSCH 1 and PDSCH 2 is very short, and the overlap time of PDSCH 1 and PDSCH 2 is very long, the terminal device can wait for both PDSCH 1 and PDSCH 2 to be successfully received and then perform joint processing. Treatment method 2.

It should be understood that the foregoing is only an exemplary description, and this application does not limit how the terminal device is based on solution 3, or the terminal device is based on one or more of the above three solutions.

It should also be understood that the terminal device may also be based on solution 3, or the terminal device may select a feedback mode based on one or more of the above three solutions.

Solution 4, based on the interval between the end moments, the terminal device generates capability information.

It can also be understood that the terminal device determines the processing mode for processing the data based on the interval between the end moments.

The interval between end moments is used to indicate the time interval between the end positions of each data transmission resource in the time domain.

For example, assuming that the time domain resource allocation of PDSCH 1 is the case of (1) in Fig. 4, and the time domain resource allocation of PDSCH 2 is the case of (6) in Fig. 4, it is explained that the PDSCH 1 and PDSCH 2 The interval between end moments is 6 symbols long. For another example, assuming that the time domain resource allocation of PDSCH 1 is the case of (1) in Figure 4, and the time domain resource allocation of PDSCH 2 is the case of (2) in Figure 4, then the PDSCH 1 and PDSCH 2 are explained. The interval between the end moments of is 1 symbol length.

Illustratively, for example, assuming that the interval between the end time of PDSCH 1 and PDSCH 2 is very short, the terminal device can determine that the processing method of processing data is any one of the foregoing processing method 2 and processing method 3; for another example, suppose The interval between the ending moments of PDSCH 1 and PDSCH 2 is very long, and the terminal device may determine that the processing method for processing data is the foregoing processing method 1.

Illustratively, this scheme can also be used in combination with scheme 1. For example, assuming that the interval between the end moments of PDSCH 1 and PDSCH 2 is very short, and the transmission time lengths of PDSCH 1 and PDSCH 2 are both very short, the terminal device can wait for both PDSCH 1 and PDSCH 2 to be successfully received and then perform joint processing, namely The above processing method 2.

Illustratively, this scheme can also be used in combination with scheme 2. For example, assuming that the interval between the end moments of PDSCH 1 and PDSCH 2 is very short, and the overlap time of PDSCH 1 and PDSCH 2 is very long, the terminal device can wait for both PDSCH 1 and PDSCH 2 to be successfully received and then perform joint processing, that is, the above processing Way 2.

It should be understood that the foregoing is only an exemplary description, and this application does not limit how the terminal device is based on solution 4, or the terminal device is based on one or more of the above four solutions.

It should also be understood that the terminal device may also select the feedback mode based on solution 4, or the terminal device may select the feedback mode based on one or more of the above four solutions.

Scheme 5, based on the end time and the start time, the terminal device generates capability information.

It can also be understood that the terminal device determines the processing mode of processing data based on the end time and the start time.

It is assumed that the terminal device receives PDSCH 1 first, and then receives PDSCH 2. The end time and the start time can be used to indicate how long the terminal device receives the PDSCH 2 after receiving the PDSCH 1.

Illustratively, for example, assuming that the terminal device receives PDSCH 1 in a short time (for example, 1 symbol) after receiving PDSCH 1, the terminal device may determine that the processing method of processing data is the above processing method 2 and processing method Any one of 3; for another example, if the terminal device receives the PDSCH 1, it takes a long time (for example, 8 symbols) to receive the PDSCH 2, then the terminal device can determine that the data processing method is the above processing method 1. .

Exemplarily, this solution can also be used in combination with one or more of the above four solutions.

It should be understood that the foregoing is only an exemplary description, and this application does not limit how the terminal device is based on solution 5, or the terminal device is based on one or more of the above five solutions.

It should also be understood that the terminal device may also be based on solution 5, or the terminal device may select a feedback mode based on one or more of the above five solutions.

Scheme 6, based on the timing deviation of the TRP at the sending and receiving point, the terminal device generates capability information.

It can also be understood that the terminal device determines the processing mode of processing data based on the timing deviation of the TRP.

The timing deviation of the TRP at the sending and receiving point can be used to indicate the time deviation or synchronization deviation when the TRP sends downlink data.

Illustratively, for example, assuming that the timing deviation of the TRP is small, the terminal device can determine that the processing method of processing data is the above processing method 2 or the above processing method 3; for another example, assuming that the TRP timing deviation is large, the terminal device can Determine the processing method for processing the data as the above processing method 1.

Exemplarily, this solution can also be used in combination with one or more of the above five solutions.

It should be understood that the foregoing is only an exemplary description, and this application does not limit how the terminal device is based on solution 6 or the terminal device is based on one or more of the above six solutions.

It should also be understood that the terminal device may also be based on solution 6, or the terminal device may select a feedback mode based on one or more of the above six solutions.

It should also be understood that the above exemplarily lists six solutions, and the application is not limited thereto. For example, the above six schemes can be used alone or in combination. For another example, the terminal device may also determine the processing method of processing data according to the start time or the end time.

Optionally, there are many ways for the terminal device to obtain the transmission information of the multiple data.

In a possible implementation manner, the terminal device obtains the transmission information of the multiple data from the network device.

The network device can notify the terminal device of the transmission information of the multiple data through a single signaling. Alternatively, the network device may indicate the transmission information of the multiple data to the terminal device when requesting the processing time capability of the terminal device.

In another possible implementation manner, the transmission information is preset.

For example, the terminal device defaults to the end symbol of the PDSCH, and another PDSCH may end within a time period of 0 to N symbols. Use this as a premise to report the PDSCH processing time. Among them, N is an integer greater than zero.

The foregoing details the solution of design 1 mentioned in step 310, and the following briefly introduces design 2.

In the embodiment of the present application, the terminal device may also report according to single station transmission.

Under this design, two scenarios are considered.

Scenario 1: The network device schedules a piece of data.

In this scenario, the network device can determine the downlink data processing time T _proc,1 for the terminal device according to Formula ₁ .

Scenario 2: The network device schedules multiple data.

In this scenario, the network device may first process the value corresponding to the original capability information (for example, the value corresponding to N1 determined by Table 1 or Table 2), and then determine the downlink data processing time T _proc,1 for the terminal device.

Among them, the original capability information can be understood as that after the terminal device reports the capability information, the network device according to the capability information reported by the terminal device according to the value corresponding to N1 as determined in Table 1 or Table 2.

Optionally, the network device may add an offset value after the original N1, and the offset value may be predefined.

For example, the network device may calculate the downlink data processing time T _proc,1 for the terminal device according to formula 4.

T _proc,1 = (N1+Δ+d _1,1 )(2048+144)*k2 ^-μ *Tc formula 4

Among them, Δ represents a value related to multiple data transmission (such as an offset value);

The value N1 corresponding to the capability information can be determined through Table 1 or Table 2 above.

It should be understood that in the solution of Design 2, the network device can determine Δ according to transmission information based on multiple data. For example, the network device can determine Δ according to one or more of the following information: the transmission time of each data, the transmission time of multiple data Overlap time, start time, interval between start times, end time, interval between end times, timing deviation of TRP at sending and receiving points, configuration parameters of multiple data, configuration parameters of DMRD, or configuration parameters of PDCCH Wait. For details, reference may be made to the above-mentioned embodiment, which will not be repeated here.

As an example, take the network device determining Δ according to the configuration parameters of the PDCCH as an example.

For example, the terminal device determines the offset value according to the time domain information where multiple PDCCHs are located. For example, the terminal device corresponds to multiple search space sets, and the group identifiers (COPRESETPoolIndex) of the control resource groups (CORESET) corresponding to the multiple search space sets are different.

One possible way is to determine Δ according to multiple search space sets and/or the symbol length of CORESET. For example, suppose that the time domain positions of the CORESET corresponding to multiple search space sets in the same time slot are completely the same or partially overlapped, or the time domain positions of the corresponding CORESETs of multiple search space sets in the same time slot are adjacent , Then in this case, Δ can be determined based on multiple search space sets and/or the symbol length of CORESET.

Assume that multiple search space sets include Searchspace set 1 and Searchspace set 2. For example, Searchspace set 1 corresponds to CORESET 1, and Searchspace set 2 corresponds to CORESET 2. In the same time slot, if it is marked as slot n, Searchspace set 1 and Searchspace set 2 respectively correspond to the start symbols of slot n as X1 and X2, and X1 and X2 are integers greater than or equal to 0. The length of CORESET 1, CORESET 2 is L1, L2, L1, L2 are positive integers, such as 1, 2, 3, etc. Then, if X1=X2 and L1=L2, it means that the time domain positions of the CORESET corresponding to multiple search space sets in the same time slot are exactly the same. If the parts from X1 to X1+L1-1 and from X2 to X2+L2-1 are the same, it means that the time domain positions of the corresponding CORESETs in the same time slot for multiple search space sets are partially overlapped. If X1+L1 is the same as X2, or X2+L2 is the same as X1, it means that the time domain positions of the corresponding CORESETs in the same time slot of multiple search space sets are adjacent.

In the embodiment of the present application, Δ can be determined according to multiple search space sets and/or the symbol length of CORESET. In a possible implementation manner, in the later PDCCH with the end symbol of the time domain, the part of the time later than the earlier PDCCH end as Δ. For example, if PDCCH1 is between X1 and X1+L1-1, PDCCH2 is between X2 and X2+L2-1, and X2+L2-1>X1+L1-1, it will be between X1+L1 and X2+L2-1 The symbol is Δ.

It should be understood that the foregoing is only an exemplary description.

It should be understood that the Δ may also be associated with the transmission of multiple data, for example, Δ is associated with a processing method, and/or Δ is associated with a feedback method. For details, reference may be made to the above-mentioned embodiment, which will not be repeated here.

For example, a network device (such as a base station) schedules 2 PDSCHs to the terminal device, and the end symbol time of the 2 PDSCHs differs by 3 symbols, then the network device can calculate the downlink data processing time T _proc,1 for the terminal device according to formula 4. At that time, 3 symbols are added in addition to N1.

It should be understood that, in some of the foregoing embodiments, the data is described as PDSCH as an example, but this does not limit the application. For example, the data may also be other types of data.

Based on the above technical solution, considering for example multi-station transmission scenarios, when a terminal device reports capability information, it can consider the transmission information of multiple data, generate capability information based on the transmission information of the multiple data, and report the capability information to the network device , So that the network device can configure the feedback resource based on the ability of the terminal device under multi-station transmission, so that not only the feedback resource can be reasonably configured, but also the system performance can be guaranteed.
