The system architecture and business scenarios described in the embodiments of this application are intended to illustrate the technical solutions of the embodiments of this application more clearly, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. Those of ordinary skill in the art will know that with the network With the evolution of architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are equally applicable to similar technical problems.

The following first briefly describes the application scenarios of the embodiments of the present application.

The eMBB service and the URLLC service have different requirements for reliability. Among them, the eMBB service requires 90% of reliability, while the URLLC service requires 99.9999% of reliability. When the terminal device has both the URLLC service and the eMBB service, if the PUCCH transmission power corresponding to the eMBB service is used, the transmission reliability of the URLLC service will be reduced, and the URLLC service transmission will fail. If the transmission power of the PUCCH corresponding to the URLLC service is used to transmit the eMBB service, the power of the terminal equipment will be wasted and the interference of the neighboring cells will be increased. Therefore, when a terminal device has different types of services at the same time, how to enable the terminal device to determine the transmission power of the PUCCH corresponding to the service to meet the reliability requirements of different services is a technical problem to be solved in the embodiment of the present application.

In the embodiments of this application, in consideration of the above problems, a communication method is proposed. The terminal device obtains at least two PUCCH transmission power parameters. The at least two PUCCH transmission power parameters have a corresponding relationship with at least two PUCCH sets. According to the target PUCCH According to the corresponding relationship, the PUCCH transmission power parameter corresponding to the target PUCCH is determined, the target PUCCH corresponds to one PUCCH set of at least two PUCCH sets, and the transmission power of the target PUCCH is determined according to the PUCCH transmission power parameter corresponding to the target PUCCH. Since each PUCCH set in the at least two PUCCH sets corresponds to a different service type, and the target PUCCH corresponds to one PUCCH set in the at least two PUCCH sets, the terminal device can determine according to the target PUCCH corresponding to the service type The PUCCH transmission power parameter corresponding to the target PUCCH is then determined to determine the transmission power of the target PUCCH. In this way, when the terminal device has different types of services at the same time, it can be determined according to the PUCCH corresponding service type, for example, the set of different PUCCH corresponding to different service types. The transmit power of the target PUCCH corresponding to the service can satisfy the reliability requirements of different services.

Hereinafter, the technical solution of the present application will be described in detail through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

It is worth noting that in the embodiments of this application, PUCCH is taken as an example for description. In practical applications, it may also be other uplink channels, such as physical uplink shared cHannel (PUSCH) or channel sounding reference signal (sounding reference). signal; SRS) channel, the power determination method for other uplink channels is similar to the PUCCH power determination method, and will not be repeated here.

Figure 2 is a signaling interaction diagram of the communication method of this application. This embodiment is described with the information interaction between the terminal device and the network device in the communication system. Based on the system architecture shown in FIG. 1, as shown in FIG. 2, in this embodiment, the communication method may include the following steps:

Step 201: The terminal device obtains at least two PUCCH transmission power parameters, and the at least two PUCCH transmission power parameters have a corresponding relationship with at least two PUCCH sets.

Among them, the PUCCH transmit power parameters include: initial PUCCH transmit power parameters p0-PUCCH-Value values and/or reference signal parameters referencesignal values. In practical applications, the PUCCH transmission power parameter may also include other power parameters, such as the frequency domain bandwidth where the PUCCH resource is located or the PUCCH transmission power adjustment element, which is not limited in this application.

In this step, the PUCCH transmit power can be determined according to formula (1):

Among them, P _{PUCCH, b, f, c} are the transmit power of PUCCH in the serving cell, b is the partial bandwidth (bandwidth part; BWP) part of the transmission bandwidth index, f is the carrier index, c is the serving cell, and i is the transmission of PUCCH Period, q _u is the initial PUCCH transmission power index, μ is the sub-carrier interval, where μ=0 represents the sub-carrier interval is 15Khz, μ=1 represents the sub-carrier interval is 30Khz, μ=2 represents the sub-carrier interval is 60Khz, μ ＝3 means that the sub-carrier spacing is 120Khz, μ=4 means that the sub-carrier spacing is 240Khz, q _d is the reference signal resource index, l is the power control adjustment state index, P _{CMAX,, f, c} are the terminal equipment allowed to be in the carrier and service The maximum power transmitted on the cell, _{PO_PUCCH, b, f, c} are the initial PUCCH transmission power,

Is the frequency domain bandwidth where the current PUCCH resource is located, PL _{b, f, c} (q _d ) is the path loss value, Δ _{TF, b, f, c} (i) is the PUCCH transmission power adjustment element, and g _{b, f, c} is Closed loop power control adjustment status.

It can be seen from formula (1) that when determining the transmission power of the target PUCCH, it is first necessary to determine the initial target PUCCH transmission power P _{O_PUCCH,b,f,c} , where P _{O_PUCCH,b,f,c are} equal to _{PO_NOMINAL_PUCCH} and _{PO_UE_PUCCH} The sum of (q _u ), _{PO_NOMINAL_PUCCH} is the initial transmission power of the target PUCCH of the cell, and P _{O_UE_PUCCH} (q _u ) is the initial transmission power of the user-specific target PUCCH.

Among them, _{PO_UE_PUCCH} (q _u ) is associated with the target initial PUCCH transmission power parameter (p0-PUCCH-Value values), and the target initial PUCCH transmission power parameter and the target initial PUCCH transmission power parameter index (p0-PUCCH-Id index) are one There is a corresponding relationship between the target initial PUCCH transmission power parameter index and the spatial relation information index (spatial relation information id).

Further, PL _{b, f, c} (q _d ) are associated with target reference signal parameters (reference signal values), and there is a relationship between the target reference signal parameters and the target PUCCH path loss reference signal parameter index (pucch-PathlossReferenceRS-Id) Corresponding relationship, there is a corresponding relationship between the target PUCCH path loss reference signal identification index and the spatial relation information index (spatial relation information id).

Based on this, in practical applications, the terminal device can obtain at least two PUCCH transmit power parameters through the spatial related information index indicated by the network device or the predefined target PUCCH transmit power parameter index to determine _{PO_UE_PUCCH} (q _u ) and/ Or PL _{b, f, c} (q _d ) to calculate the transmit power of the target PUCCH.

In a possible implementation manner, the terminal device may be pre-configured with multiple spatial related information indexes, and the network device will send a first message to the terminal device. The first message is used to indicate the target in the multiple spatial related information indexes. The space related information index, the terminal device will obtain at least two PUCCH transmit power parameters corresponding to the target space related information index. It is understandable that the first message may be an activation command sent by the network device through a media access control layer (Media Access Control; MAC). Of course, the first message may also be other high-level signaling. The target spatial related information index may be one or more spatial related information indexes.

Specifically, the network device pre-configures multiple spatial related information indexes for the terminal device through the second message sent to the terminal device, for example, at least two spatial related information indexes may be configured. Wherein, the second message may be a radio resource control (Radio Resource Control; RRC) message, or may be other high-level signaling. Exemplarily, when the terminal device is configured with multiple spatial related information indexes, the terminal device obtains a first correspondence relationship, where the first correspondence relationship is a correspondence relationship between a PUCCH transmission power parameter set and a spatial related information index set. For example, the terminal device determines the first correspondence relationship through at least one PUCCH transmission power parameter index. It can be understood that a PUCCH transmit power parameter index includes a first correspondence between at least two PUCCH transmit power parameters and a spatial related information index, or a PUCCH transmit power parameter index includes one PUCCH transmit power parameter and one spatial related information The first correspondence between the index.

In the embodiments of the present application, high-level signaling may refer to signaling sent by a high-level protocol layer, and the high-level protocol layer is at least one protocol layer above the physical layer. Among them, the high-level protocol layer may specifically include at least one of the following protocol layers: Medium Access Control (MAC) layer, Radio Link Control (RLC) layer, Packet Data Convergence Protocol (Packet Data Convergence) Protocol, PDCP) layer, radio resource control (RRC) layer, non-access stratum (NAS), etc.

It should be noted that when the network device pre-configures a space-related information index for the terminal device through the second message sent to the terminal device, the terminal device can directly index the space-related information and determine it as the target space-related information index .

Further, when acquiring at least two PUCCH transmit power parameters corresponding to the target space related information index, the terminal device may determine the target PUCCH transmit power parameter index corresponding to the target space related information index, and determine the target PUCCH transmit power parameter index and The correspondence between multiple PUCCH transmission power parameters determines at least two PUCCH transmission power parameters corresponding to the target PUCCH transmission power parameter index.

Among them, the target PUCCH transmission power parameter index includes: the initial target PUCCH transmission power parameter index p0-PUCCH-Id index and/or the target PUCCH path loss reference signal parameter index pucch-PathlossReferenceRS-Id index.

Exemplarily, there is a correspondence between the target space-related information index and the target PUCCH transmission power parameter index. For example, one target space-related information index may correspond to one target PUCCH transmission power parameter index, or multiple target space-related information indexes correspond to One target PUCCH transmission power parameter index, or one target space related information index corresponds to multiple target PUCCH transmission power parameter indexes.

Implementation mode 1: The target space-related information index may be a space-related information index. One spatial related information index may correspond to one target PUCCH transmit power parameter index. The one target PUCCH transmission power parameter index may correspond to at least two PUCCH transmission power parameters. The terminal device will determine at least two PUCCH transmission power parameters according to a target PUCCH transmission power parameter index.

Implementation manner 2: The target spatial related information index may be at least two spatial related information indexes. One spatial related information index may correspond to at least one target PUCCH transmit power parameter index. One target PUCCH transmission power parameter index may correspond to at least one PUCCH transmission power parameter. The terminal device will determine at least two PUCCH transmission power parameters according to at least one target PUCCH transmission power parameter index. Exemplarily, in the case where one spatial related information index corresponds to one target PUCCH transmission power parameter index, and one target PUCCH transmission power parameter index corresponds to one PUCCH transmission power parameter, the terminal device needs to determine at least Two PUCCH transmit power parameters. Or, exemplarily, in a case where one spatial related information index corresponds to at least two target PUCCH transmission power parameter indexes, or, in a case where one target PUCCH transmission power parameter index corresponds to at least two PUCCH transmission power parameters, the terminal device may use at least Two spatial related information indexes determine at least two PUCCH transmission power parameters, or at least two PUCCH transmission power parameters may be determined based on only one spatial related information index.

For another example, when one target space-related information index corresponds to multiple target PUCCH transmission power parameter indexes, generally, the terminal device will select one of the target PUCCH transmission power parameter indexes according to a preset rule, such as from the target space-related information index corresponding to multiple indexes. Among the target PUCCH transmission power parameter indexes, the first target PUCCH transmission power parameter index is selected.

Implementation mode 3: The target space-related information index may be a space-related information index. One spatial related information index may correspond to at least two target PUCCH transmit power parameter indexes. One target PUCCH transmission power parameter index may correspond to at least one PUCCH transmission power parameter. The terminal device will determine at least two PUCCH transmission power parameters according to at least two target PUCCH transmission power parameter indexes.

In addition, there is also a corresponding relationship between the target PUCCH transmission power parameter index and multiple PUCCH transmission power parameters. Based on the corresponding relationship, the terminal device determines the target PUCCH transmission power parameter index corresponding to the target space related information index. From the multiple PUCCH transmission power parameters, determine at least two PUCCH transmission power parameters corresponding to the target PUCCH transmission power parameter index. The terminal device obtains a second correspondence, where the second correspondence is a correspondence between multiple PUCCH transmission power parameters and multiple PUCCH transmission power parameter indexes. Specifically, one PUCCH transmission power parameter index corresponds to at least two PUCCH transmission power parameters, or one PUCCH transmission power parameter index corresponds to one PUCCH transmission power parameter.

In the above manner, after the terminal device is configured with multiple spatial related information indexes, the network device will send a first message to the terminal device to indicate the target spatial related information index among the multiple spatial related information indexes, thereby determining the target The target PUCCH transmit power parameter index corresponding to the space-related information index is used to obtain at least two PUCCH transmit power parameters corresponding to the target PUCCH transmit power parameter index, so that at least two PUCCH transmit power parameters can be activated and configured for the terminal device, and then the terminal device When supporting transmissions corresponding to multiple different services at the same time, the terminal device can determine the PUCCH transmission power parameter used according to the currently transmitted service.

In another possible implementation manner, the terminal device may also obtain a predefined target PUCCH transmission power parameter index, and according to the predefined target PUCCH transmission power parameter index and the correspondence between multiple PUCCH transmission power parameters, Obtain at least two PUCCH transmission power parameters corresponding to a predefined target PUCCH transmission power parameter index. Specifically, if the space-related information index is not configured in the terminal device, at this time, the terminal device will obtain at least two PUCCH transmissions from multiple PUCCH transmission power parameters that have a corresponding relationship with the predefined target PUCCH transmission power parameter index. Power parameters.

In this embodiment, the aforementioned at least two PUCCH transmit power parameters have a corresponding relationship with at least two PUCCH sets. Exemplarily, there is a one-to-one correspondence between at least two PUCCH transmission power parameters and at least two PUCCH sets, or one PUCCH transmission power parameter in the at least two PUCCH transmission power parameters may correspond to m of the at least two PUCCH sets The PUCCH set, or n PUCCH transmit power parameters in the at least two PUCCH transmit power parameters may correspond to one PUCCH set in the at least two PUCCH sets, where both m and n are integers greater than 1.

Exemplarily, the foregoing at least two PUCCH sets may include a first PUCCH set and a second PUCCH set, or the at least two PUCCH sets include a first PUCCH set, a second PUCCH set, and a third PUCCH set. The third PUCCH set It is one PUCCH set excluding the first PUCCH set and the second PUCCH set among the at least two PUCCH sets.

Wherein, each PUCCH set in the at least two PUCCH sets includes at least one PUCCH, and each PUCCH set may correspond to a service type. For example: the first PUCCH set corresponds to the URLLC service, that is, the PUCCH in the first PUCCH set is used to transmit the information of the URLLC service, and the second PUCCH set corresponds to the eMBB service, that is, the PUCCH in the second PUCCH set is used to transmit the information of the eMBB service. Or, the first PUCCH set corresponds to URLLC services, the second PUCCH set corresponds to eMBB services, and the third PUCCH set corresponds to eMBB services and URLLC services, that is, the PUCCH in the third PUCCH set is used to simultaneously transmit eMBB service information and URLLC service information . Wherein, the service information may be control information corresponding to the service and/or data information corresponding to the service.

It is understandable that the PUCCH included in the first PUCCH set and the PUCCH included in the second PUCCH set are different, or the PUCCH included in the first PUCCH set, the PUCCH included in the second PUCCH set, and the PUCCH included in the third PUCCH set are different The PUCCHs are different. That is, the same PUCCH cannot correspond to the first PUCCH set and the second PUCCH set at the same time, or the same PUCCH cannot correspond to the first PUCCH set, the second PUCCH set, and the third PUCCH set at the same time. Different PUCCHs can be understood as PUCCHs that carry different types of information, such as different types of uplink control information (UCI). UCI includes hybrid automatic repeat request (HARQ) and scheduling request (scheduling). request, SR) or channel state information (CSI); or different PUCCHs can be understood as different ways to trigger PUCCH transmission. For example, the way to trigger PUCCH transmission includes periodic PUCCH transmission, downlink control information (downlink control information) , DCI) triggered PUCCH, semi-permanently sent PUCCH, and predefined or high-level signaling configured DCI triggered PUCCH; or, PUCCH is different can be understood as PUCCH corresponding to different time-frequency resources, for example, The time-frequency resource includes at least one of the start symbol, the end symbol, or the number of symbols occupied by the PUCCH.

Exemplarily, each PUCCH set includes identification information, and different PUCCH sets correspond to different identification information, that is, the identification information corresponding to the first PUCCH set and the second PUCCH set are different, or the first PUCCH set , The identification information corresponding to the second PUCCH set and the third PUCCH set are different.

Step 202: The terminal device determines the PUCCH transmit power parameter corresponding to the target PUCCH according to the target PUCCH and the corresponding relationship, and the target PUCCH corresponds to one of the at least two PUCCH sets.

In this step, because the target PUCCH corresponds to one PUCCH set in at least two PUCCH sets, and at least two PUCCH transmission power parameters have a corresponding relationship with at least two PUCCH sets. Therefore, according to the correspondence between the at least two PUCCH transmission power parameters and the at least two PUCCH sets, the PUCCH transmission power parameter corresponding to the target PUCCH can be determined.

Exemplarily, the target PUCCH corresponds to one PUCCH set in at least two PUCCH sets. It can be understood that the target PUCCH is included in one PUCCH set in at least two PUCCH sets, or one PUCCH set in at least two PUCCH sets includes The target PUCCH can also be understood as meaning that the content or corresponding attributes carried by the target PUCCH are the same as one PUCCH set in at least two PUCCH sets. For example, the information type or sending mode or time-frequency resource corresponding to the target PUCCH is the same as at least two PUCCH sets. One PUCCH set in the PUCCH set is the same. In the specific implementation process, which PUCCH set corresponds to the target PUCCH can be determined according to the following manner:

When the first condition is satisfied, the target PUCCH corresponds to the first PUCCH set, and when the first condition is not satisfied, the target PUCCH corresponds to the second PUCCH set. The first condition includes at least one of the following: the format of the DCI corresponding to the target PUCCH is the first format, or the radio network temporary identity (RNTI) of the DCI corresponding to the scrambling target PUCCH is the first RNTI, Alternatively, the bit state of the first bit field in the DCI corresponding to the target PUCCH is the first bit state, or the search space where the DCI corresponding to the target PUCCH is located is the first search space, or the control resource where the DCI corresponding to the target PUCCH is located The set belongs to the first control resource set group, or the index of the search space where the DCI corresponding to the target PUCCH is located belongs to the first search space index group, or the scheduling request resource index corresponding to the SR carried by the target PUCCH belongs to the first scheduling request resource index set.

The DCI corresponding to the target PUCCH can be understood as the DCI that triggers the transmission of the target PUCCH. For example, there is a PUCCH indication field in the DCI, and the DCI indicates the time-frequency resource of the target PUCCH, and the terminal device transmits the target PUCCH. For another example, there is a preset correspondence between the DCI and the target PUCCH. After the terminal device receives the DCI, the target PUCCH is determined by the preset correspondence, and the terminal device transmits the target PUCCH.

Exemplarily, the format of the DCI corresponding to the target PUCCH includes at least one of the format of the DCI indicating the downlink data channel and the format of the DCI that triggers the CSI. The format of the DCI indicating the downlink data channel is used to indicate the transmission of corresponding control information on the downlink channel corresponding to HARQ. The format of the DCI includes any of the following formats: DCI format 1_0, DCI format 1_1, or DCI format 1_2. Of course, other formats may also be used, which is not limited in this embodiment.

Wherein, when the format of the DCI corresponding to the target PUCCH is the first format, the target PUCCH corresponds to the first PUCCH set. When the format of the DCI corresponding to the target PUCCH is not the first format, for example, when the format of the DCI corresponding to the target PUCCH is the second format, the target PUCCH corresponds to the second PUCCH set. Optionally, the first format may be DCI format 1_2, and the second format may be DCI format 1_0 or DCI format 1_1, or the first format may be DCI format 1_0, and the second format may be DCI format 1_1 or DCI format 1_2, Alternatively, the first format may be DCI format 1_1, and the second format may be DCI format 1_0 or DCI format 1_2. Of course, the first format can also be any two of the above three formats, and the second format can be other formats than the first format. Regarding the specific forms of the first format and the second format, this embodiment is There is no restriction.

It can be understood that the number of bits corresponding to DCI format 1_2 is less than the number of bits corresponding to DCI format 1_0. For example, the bit difference between DCI format 1_2 and DCI format 1_0 is less than or equal to any bit value between 10 bits and 16 bits. The number of bits corresponding to DCI format 0_2 is less than the number of bits corresponding to DCI format 0_0. For example, the bit difference between DCI format 0_2 and DCI format 0_0 is less than or equal to any bit value between 10 bits and 16 bits.

Regarding the format of the DCI that triggers CSI, it includes any of the following formats: DCI format 0_0, DCI format 0_1, DCI format 0_2, DCI format 1_0, DCI format 1_1, and DCI format 1_2. Of course, it can also be other formats. This embodiment is not limited here. Among them, DCI format 0_0, DCI format 0_1, and DCI format 0_2 are used to indicate the control information corresponding to the uplink channel transmission.

Wherein, when the format of the DCI corresponding to the target PUCCH is the first format, the target PUCCH corresponds to the first PUCCH set. When the format of the DCI corresponding to the target PUCCH is not the first format, for example, when the format of the DCI corresponding to the target PUCCH is the second format, the target PUCCH corresponds to the second PUCCH set. Optionally, the first format may be DCI format 0_2, and the second format may be DCI format 0_0 and DCI format 0_1. Of course, the first format can also be other formats among the above six formats, and the second format can be a format other than the first format. For the specific forms of the first format and the second format, this embodiment will not do it here. limit.

Further, when the format of the DCI corresponding to the target PUCCH is neither the first format nor the second format, it may be determined that the target PUCCH corresponds to the third PUCCH set. The third PUCCH set is one PUCCH set excluding the first PUCCH set and the second PUCCH set among the at least two PUCCH sets.

Exemplarily, for each Physical Downlink Control Channel (Physical Downlink Control Channel; DCI carried by PDCCH, PUCCH will use RNTI to scramble the DCI cyclic redundancy check (CRC), and the terminal device can also Different DCIs are distinguished by RNTI. Among them, RNTI can be one of the following: system information RNTI (System Information-RNTI; SI-RNTI), random access RNTI (random access-RNTI; RA-RNTI), temporary cell RNTI (temporary cell-RNTI; TC-RNTI), paging-RNTI (paging-RNTI; P-RNTI), cell RNTI (cell-RNTI; C-RNTI), configured scheduling-RNTI (configured scheduling-RNTI; CS-RNTI) or Modulation and coding scheme cell RNTI (Modulation and coding scheme cell RNTI; MCS-C-RNTI) may also be other RNTI, and this embodiment does not limit the form of RNTI.

Wherein, when the RNTI of the DCI corresponding to the scrambled target PUCCH is the first RNTI, the target PUCCH corresponds to the first PUCCH set. When the RNTI of the DCI corresponding to the scrambled target PUCCH is not the first RNTI, such as the second RNTI, the target PUCCH corresponds to the second PUCCH set. Optionally, the first RNTI may be MCS-C-RNTI, and the second RNTI may be C-RNTI. Of course, the first RNTI and the second RNTI may also be other types of RNTI. For the first RNTI and the second RNTI, The specific form is not limited in the embodiment of the present application.

Further, when the RNTI of the DCI corresponding to the scrambled target PUCCH is neither the first RNTI nor the second RNTI, it may be determined that the target PUCCH corresponds to the third PUCCH set.

Exemplarily, the DCI includes one or more bit fields, and each bit field is used to indicate control information. The bit state of the first bit field in the DCI corresponding to the target PUCCH includes at least one of the bit state of the first bit field in the DCI indicating the downlink data channel and the bit state of the first bit field in the DCI that triggers CSI Kind. When the bit state of the first bit field in the DCI corresponding to the target PUCCH is the first bit state, the target PUCCH corresponds to the first PUCCH set, and the bit state of the first bit field in the DCI corresponding to the target PUCCH is not the first bit State, if it is the second bit state, the target PUCCH corresponds to the second PUCCH set. Optionally, the first bit field may be 1 bit, the first bit state may be 0, and the second bit state may be 1.

Further, when the bit state of the first bit field in the DCI corresponding to the target PUCCH is neither the first bit state nor the second bit state, it can be determined that the target PUCCH corresponds to the third PUCCH set. For example: the first bit field is 2 bits, the first bit state is 00, the second bit state is 01, the third bit state and the fourth bit state are 10/11, that is, the first bit field in the DCI corresponding to the target PUCCH When the bit state of is the third bit state 10 or the fourth bit state 11, the target PUCCH corresponds to the third PUCCH set.

Exemplarily, a group of candidate PDCCHs that the terminal device can monitor is usually defined as a PDCCH search space set. Among them, the type of search space set (search space set) may include: common search space set (common search space set) or user-specific search space set (UE-specific search space set). Common search space set (common search space set) can also include: Type0-PDCCH common search space set, Type0A-PDCCH common search space set, Type1-PDCCH common search space set, Type2-PDCCH common search space set, or Type3-PDCCH common Search space collection.

Wherein, the search space where the DCI corresponding to the target PUCCH is located includes at least one of the search space indicating the DCI of the downlink data channel and the search space where the DCI that triggers the CSI is located. When the search space where the DCI corresponding to the target PUCCH is located is the first search space, the target PUCCH corresponds to the first PUCCH set. When the search space where the DCI corresponding to the target PUCCH is located is not the first search space, such as the second search space, the target PUCCH corresponds to the second PUCCH set. Optionally, the first search space may be a set of user-specific search spaces, and the second search space may be a set of public search spaces, or the first search space may be a set of public search spaces, and the second search space may be a user-specific search Space collection. The specific forms of the first search space and the second search space are not limited in this embodiment of the present application.

Further, when the search space where the DCI corresponding to the target PUCCH is located is neither the first search space nor the second search space, it may be determined that the target PUCCH corresponds to the third PUCCH set.

Exemplarily, when the index of the search space where the DCI corresponding to the target PUCCH is located belongs to the first search space index group, the target PUCCH corresponds to the first PUCCH set, and the index of the search space where the DCI corresponding to the target PUCCH is located does not belong to the first search In the spatial index group, if it belongs to the second search spatial index group, the target PUCCH corresponds to the second PUCCH set.

Further, when the index of the search space where the DCI corresponding to the target PUCCH is located neither belongs to the first search space index group nor the second search space index group, it can be determined that the target PUCCH corresponds to the third PUCCH set.

Exemplarily, DCI needs to be transmitted in a control resource set (Control Resource Set, CORESET), which is configured through high-level signaling. Among them, the control resource set includes physical resources of multiple resource element groups (REG). A control resource set can occupy 1, 2 or 3 symbols in the time domain, and one or more symbols in the frequency domain. Resource blocks. One control resource set may contain multiple search spaces, and one search space corresponds to at least one control resource set.

Wherein, the control resource set where the DCI corresponding to the target PUCCH is located includes at least one of the control resource set indicating the DCI of the downlink data channel and the control resource set where the DCI triggering the CSI is located. When the control resource set where the DCI corresponding to the target PUCCH is located belongs to the first control resource set group, the target PUCCH corresponds to the first PUCCH set. When the control resource set where the DCI corresponding to the target PUCCH is located does not belong to the first control resource set group, for example, when it belongs to the second control resource set group, the target PUCCH corresponds to the second PUCCH set.

Further, when the control resource set where the DCI corresponding to the target PUCCH is located neither belongs to the first control resource set group nor the second control resource set group, it may be determined that the target PUCCH corresponds to the third PUCCH set.

Exemplarily, multiple scheduling request resource index sets may be configured through high-level signaling or a predefined manner. When the scheduling request resource index corresponding to the SR carried by the target PUCCH belongs to the first scheduling request resource index set, the target PUCCH corresponds to the first scheduling request resource index set. PUCCH set; or the scheduling request resource index corresponding to the SR carried by the target PUCCH does not belong to the first scheduling request resource index set. If it belongs to the second scheduling request resource index set, the target PUCCH corresponds to the second PUCCH set.

Further, when the scheduling request resource index corresponding to the SR carried by the target PUCCH does not belong to the first scheduling request resource index set or the second scheduling request resource index set, it may be determined that the target PUCCH corresponds to the third PUCCH set.

It is worth noting that the above-mentioned first condition and/or second condition may be configured through higher layer signaling, or may be predefined.

Exemplarily, as a possible implementation manner, when determining which PUCCH set the target PUCCH corresponds to, it may also be determined according to the identification information corresponding to the PUCCH and the identification information of each PUCCH set. Specifically, since each PUCCH set corresponds to one piece of identification information, and the target PUCCH may also include the identification information of the PUCCH set. When it is determined that the identification information corresponding to the target PUCCH is the same as the identification information of the first PUCCH set, it will be determined that the target PUCCH corresponds to the first PUCCH set. If the identification information corresponding to the target PUCCH is the same as the identification information of the second PUCCH set, it will be determined that the target PUCCH corresponds to the second PUCCH set.

Step 203: The terminal device determines the transmission power of the target PUCCH according to the PUCCH transmission power parameter corresponding to the target PUCCH.

Exemplarily, suppose that the first PUCCH set is a set corresponding to the URLLC service, and the second PUCCH set is a set corresponding to the eMBB service. If the target PUCCH corresponds to the first PUCCH set, the determined PUCCH transmission power parameter corresponding to the target PUCCH is the PUCCH transmission power parameter corresponding to the first PUCCH set. In this way, the determined transmission power of the target PUCCH is the transmission power corresponding to the URLLC service. If the target PUCCH corresponds to the second PUCCH set, the determined PUCCH transmission power parameter corresponding to the target PUCCH is the PUCCH transmission power parameter corresponding to the second PUCCH set. In this way, the determined transmission power of the target PUCCH is the transmission power corresponding to the eMBB service. In this way, it is possible to determine the target PUCCH transmit power according to different service types.

Further, it is assumed that the target PUCCH includes the SR of the URLLC service and the HARQ of the eMBB service. For example, the first PUCCH corresponds to SR, and the second PUCCH corresponds to HARQ. Because SR can only use PUCCH format 0 and PUCCH format 1, while HARQ can use PUCCH format 0, PUCCH format 1, PUCCH format 2, PUCCH format 3, and PUCCH Format 4. Therefore, the first PUCCH and the second PUCCH may overlap or partially overlap in the time domain.

The first PUCCH carries SR through the resource corresponding to PUCCH format 1, and the second PUCCH carries HARQ through the resource corresponding to PUCCH format 1. If the SR is positive SR (positive SR), it will be used on the resource of PUCCH format 1 where the SR is located The transmission power corresponding to HARQ sends HARQ; if SR is negative SR (negative SR), then the transmission power corresponding to HARQ is used to send HARQ information on the resource of PUCCH format 1 where HARQ is located. The network device can blindly detect the location of the first PUCCH resource and the second PUCCH resource to determine whether the current terminal device is sending a positive SR or a negative SR. Among them, positive SR indicates that the terminal device currently has a request for uplink data transmission, and negative SR indicates that the terminal device currently has no request for uplink data transmission.

The first PUCCH carries SR through the resource corresponding to PUCCH format 0, and the second PUCCH carries HARQ through the resource corresponding to PUCCH format 0. If the SR is positive SR (positive SR), it will be used on the resource of PUCCH format 0 where HARQ is located SR is sent at the transmit power corresponding to HARQ, and at the same time, the sequence information corresponding to the second PUCCH is also sequenced; if SR is negative SR (negative SR), then HARQ corresponding to the resource of PUCCH format 0 where HARQ is located will be used The HARQ information is transmitted at the transmit power. At this time, the sequence information corresponding to the second PUCCH will not be sequenced.

Among them, when performing sequence transformation on the sequence information corresponding to the second PUCCH, when HARQ is 1 bit and SR is positive SR, the terminal device can transform the sequence in the following manner: the sequence index corresponding to positive SR+1 (ACK) is {Initial sequence index+3}, the sequence index corresponding to positive SR+0 (NACK) is {initial sequence index+9}. When HARQ is 2bit and SR is positive SR, the terminal device can transform the sequence in the following way: the sequence index corresponding to positive SR+00 (NACK, NACK) is {initial sequence index+1}, positive SR+01( The sequence index corresponding to NACK, ACK) is {initial sequence index+4}, the sequence index corresponding to positive SR+11 (ACK, ACK) is {initial sequence index+7}, and the sequence index corresponding to positive SR+11 (ACK, NACK) The sequence index is {initial sequence index+10}. Exemplarily, the foregoing initial sequence index may be configured by high-level signaling.

It can be seen from the above content that when the target PUCCH is transmitted through the transmission power corresponding to HARQ, assuming that the HARQ corresponds to the eMBB service, the transmission reliability of the SR of the URLLC service cannot be guaranteed.

In the embodiments of this application, the above-mentioned problems can be solved in the following two ways:

In an implementation manner, the target PUCCH corresponds to the first PUCCH set, the first PUCCH set has a corresponding relationship with the first PUCCH, and the first PUCCH corresponds to the first uplink control information (UCI) included in the target PUCCH, There is a correspondence between the second PUCCH set and the second PUCCH, and the second PUCCH corresponds to the second UCI included in the target PUCCH. The uplink control information UCI generally includes: HARQ, SR and CSI. HARQ includes acknowledgement information (Acknowledgment, ACK) and negative acknowledgement (Negative Acknowledgement, NACK), where ACK represents successful reception at the receiving end, and NACK represents reception failure at the receiving end. SR includes positive SR and negative negative SR. Positive SR represents that the terminal device currently has a request for uplink data transmission, and negative SR represents that the terminal device does not currently have a request for uplink data transmission. CSI generally includes channel quality information (channel quality indicator, CQI), rank indicator (rank indicator, RI), precoding matrix indicator (precoding matrix indicator, PMI), channel state information reference signal resource indicator (CSI-RS resource indicator, CRI) or a combination of one or more information in the measurement link configuration set information. CSI reporting methods include aperiodic CSI, semi-persistent CSI and periodic CSI.

Specifically, when the first PUCCH corresponds to the first UCI included in the target PUCCH and the second PUCCH corresponds to the second UCI included in the target PUCCH, the target PUCCH corresponds to the first PUCCH set. At this time, the transmit power of the target PUCCH is based on the first PUCCH. The transmission power parameter corresponding to a PUCCH set is determined.

Further, the first UCI may be HARQ, and the second UCI may be SR. At this time, the first PUCCH set corresponding to the target PUCCH is the PUCCH set corresponding to the first PUCCH corresponding to HARQ. In addition, the first UCI may also be SR, and the second UCI may also be HARQ. In this case, the first PUCCH set corresponding to the target PUCCH is the PUCCH set corresponding to the first PUCCH corresponding to the SR. Wherein, HARQ may be HARQ corresponding to URLLC service, or HARQ corresponding to eMBB service, and SR may be SR corresponding to URLLC service or SR corresponding to eMBB service.

Exemplarily, after determining that the transmit power of the target PUCCH is the transmit power corresponding to the first PUCCH set, it may be further considered whether the parameter transmit power control (TPC) command word in the downlink control information that triggers HARQ is valid , Among them, the TPC command word can be effective or not. Regarding whether the TPC command word is valid, it can be set according to high-level signaling or actual conditions.

In another implementation, the target PUCCH corresponds to the third PUCCH set, the first PUCCH set corresponds to the first PUCCH, the first PUCCH corresponds to the first UCI included in the target PUCCH, and the second PUCCH set exists with the second PUCCH Correspondence, the second PUCCH corresponds to the second UCI included in the target PUCCH.

Specifically, when the third PUCCH set is also included in at least two PUCCH sets, when the first PUCCH corresponds to the first UCI included in the target PUCCH, and the second PUCCH corresponds to the second UCI included in the target PUCCH, the target PUCCH corresponds to the first UCI. Three PUCCH sets. At this time, the transmit power of the target PUCCH is determined according to the transmit power parameter corresponding to the third PUCCH set. Among them, the PUCCH in the third PUCCH set simultaneously carries information corresponding to the URLLC service and the eMBB service.

Exemplarily, after it is determined that the transmit power of the target PUCCH is the transmit power corresponding to the third PUCCH set, at this time, the TPC command word in the downlink control information that currently triggers HARQ does not take effect.

In the above two implementation manners, if the first UCI is SR, the second UCI is HARQ, and the formats of the first PUCCH and the second PUCCH are PUCCH format 0, then the target PUCCH is the physical resource block where the first PUCCH is located (physical resource block). block; PRB) on a PUCCH.

Specifically, the first PUCCH corresponds to the SR of the URLLC service, the second PUCCH corresponds to the HARQ of the eMBB service, and the first PUCCH carries the SR through the resource corresponding to PUCCH format 0, and the second PUCCH carries the HARQ through the resource corresponding to PUCCH format 0. Then the target PUCCH is a PUCCH on the PRB where the SR is located, and the transmission power parameter of the target PUCCH is determined according to the transmission power parameter corresponding to the first PUCCH set. That is, the transmission power parameter of the target PUCCH is determined according to the transmission power parameter corresponding to the SR. Optionally, the transmission power parameter corresponding to the SR may be directly determined as the transmission power parameter of the target PUCCH, or according to a preset rule, the transmission power parameter of the target PUCCH may be determined according to the transmission power parameter corresponding to the SR. At this time, the target PUCCH will be transmitted using the transmit power corresponding to the SR on the first PUCCH corresponding to the SR.

Since on the PUCCH resource corresponding to the SR, the transmission power parameter corresponding to the target PUCCH is determined according to the transmission power parameter corresponding to the SR, compared with the transmission power parameter corresponding to the target PUCCH determined according to the transmission power parameter corresponding to the HARQ of the eMBB service in the prior art In the embodiment of this application, the transmission reliability of the SR of the URLLC service can be guaranteed. In addition, if the first UCI is SR and the second UCI is HARQ, the target PUCCH is a PUCCH on the first PRB, and the index of the first PRB is the index value of the PRB where the second PUCCH is offset by the first value .

Specifically, in order to avoid the use of URLLC SR transmit power on the second PUCCH resource of eMBB HARQ, resulting in unbalanced power between CSs on the PRB where eMBB HARQ is located, and performance degradation of other eMBB HARQ, in this embodiment of the application It is also necessary to offset the physical resource block (PRB) of the target PUCCH. Assuming that the first PUCCH corresponds to the SR of the URLLC service, and the second PUCCH corresponds to the HARQ of the eMBB service, no matter whether the first PUCCH carries the SR through the resource corresponding to PUCCH format 0 or the resource corresponding to PUCCH format 1, the second PUCCH Whether to carry HARQ through the resource corresponding to PUCCH format 0 or to carry HARQ through the resource corresponding to PUCCH format 1. At this time, the target PUCCH is the PRB obtained after the index of the PRB where the second PUCCH corresponding to HARQ is offset by the first value One PUCCH.

Wherein, the first value is an integer, and its value can be configured through high-level signaling, or it can be predefined, or it can be notified by triggering the downlink control information corresponding to HARQ. The first value can be, for example, -1, 1. , 2, or -2, etc. The specific value of the first value is not limited in the embodiment of the present application.

Optionally, in order to avoid the use of URLLC SR transmit power on the second PUCCH resource of eMBB HARQ, resulting in unbalanced power among CSs on the PRB where eMBB HARQ is located, and performance degradation of other eMBB HARQ, this embodiment of the application It also needs to make sequence changes to the sequence information corresponding to the target PUCCH. Specifically, sequence transformation may be performed on the sequence information corresponding to the first PUCCH corresponding to the SR, where the step size of the sequence transformation may be pre-defined or configured through high-level signaling. Exemplarily, when HARQ is 1 bit and SR is positive SR, the terminal device can transform the sequence in the following manner: the sequence index corresponding to positive SR+1 (ACK) is {initial sequence index+3}, positive SR+ The sequence index corresponding to 0 (NACK) is {initial sequence index + 9}. When HARQ is 2bit and SR is positive SR, the terminal device can transform the sequence in the following way: the sequence index corresponding to positive SR+00 (NACK, NACK) is {initial sequence index+1}, positive SR+01( The sequence index corresponding to NACK, ACK) is {initial sequence index+4}, the sequence index corresponding to positive SR+11 (ACK, ACK) is {initial sequence index+7}, and the sequence index corresponding to positive SR+11 (ACK, NACK) The sequence index is {initial sequence index+10}. It can be understood that after the sequence information corresponding to the first PUCCH corresponding to the SR is subjected to sequence transformation, the sequence information corresponding to the target PUCCH will have a corresponding relationship with the sequence information corresponding to the first PUCCH.

Optionally, when the sequence information corresponding to the target PUCCH is changed, the sequence information corresponding to the second PUCCH corresponding to HARQ may be changed, or the preset sequence information may be changed, where the sequence change The step size of may be similar to the step size when performing sequence transformation on the sequence information corresponding to the first PUCCH corresponding to the SR, and will not be repeated here. It is understandable that after performing sequence transformation on the sequence information corresponding to the second PUCCH corresponding to HARQ, the sequence information corresponding to the target PUCCH will have a corresponding relationship with the sequence information corresponding to the second PUCCH. Later, the sequence information corresponding to the target PUCCH will have a corresponding relationship with the preset sequence information.

Exemplarily, when HARQ is 1 bit and SR is positive SR, the terminal device can transform the sequence in the following manner in addition to {initial sequence index + 3} and {initial sequence index + 9} Perform sequence transformation: {sequence index+0, sequence index+6}, {sequence index+1, sequence index+7}, {sequence index+2, sequence index+8}, {sequence index+4, sequence index+10 } And {sequence index +5, sequence index +11}. When HARQ is 2bit, SR is positive SR, except that the sequence is transformed according to {initial sequence index + 1}, {initial sequence index + 4}, {initial sequence index + 7} and {initial sequence index + 11} In addition, you can also perform sequence transformation in the following ways: {sequence index + 0, sequence index + 3, sequence index + 6, sequence index + 9}, {sequence index + 2, sequence index + 5, sequence index + 8 ,Sequence index +11}. Exemplarily, the aforementioned sequence index may be an initial sequence index, or may be another predefined sequence index, may also be a sequence index corresponding to the first PUCCH, or a sequence index corresponding to the second PUCCH.

It should be noted that when the target PUCCH is a PUCCH on the PRB obtained after the index of the PRB corresponding to the second PUCCH corresponding to HARQ is offset by the first value, the initial sequence information corresponding to the first PUCCH may also be used as the target PUCCH Corresponding sequence information, or use the initial sequence information corresponding to the second PUCCH as the sequence information corresponding to the target PUCCH.

Exemplarily, if the first UCI is HARQ, the second UCI is SR, the formats of the first PUCCH and the second PUCCH are PUCCH format 1, the target PUCCH is a PUCCH on the second PRB, and the index of the second PRB is second The index of the PRB where the PUCCH is located is offset by the index value after the second value.

Specifically, the first PUCCH corresponds to the HARQ of the eMBB service, the second PUCCH corresponds to the SR of the URLLC service, the first PUCCH is to carry HARQ through the resource corresponding to PUCCH format 1, and the second PUCCH is to carry the SR through the resource corresponding to PUCCH format 1. At this time, the target PUCCH is a PUCCH on the PRB obtained by offsetting the index of the PRB where the second PUCCH corresponding to the SR is located by the second value.

Wherein, the second value is an integer, and its value can be configured through high-level signaling, or it can be predefined, or it can be notified by triggering the downlink control information corresponding to HARQ. The second value can be, for example, -1, 1. , 2, or -2, etc. The specific value of the second value is not limited in the embodiment of the present application.

Optionally, the symbol difference between the first symbol corresponding to the first PUCCH and the second symbol corresponding to the second PUCCH is less than or equal to a preset value; and/or, the first symbol corresponding to the first PUCCH corresponds to the second PUCCH Or the first symbol corresponding to the first PUCCH is after the second symbol corresponding to the second PUCCH; and/or, the first PUCCH and the second PUCCH overlap partially or completely.

In addition, since the terminal equipment needs preparation time from demodulating the downlink data channel to feeding back the corresponding HARQ, if the SR is sent on HARQ resources, if the time difference between the first PUCCH corresponding to the SR and the second PUCCH corresponding to HARQ is greater than the preset value , When sending HARQ and SR, it will happen that the information sent later cannot be obtained, causing the target PUCCH to fail to send. For example: if the first PUCCH corresponding to SR is before the second PUCCH corresponding to HARQ, and the time difference between the first PUCCH and the second PUCCH is greater than the preset value, the terminal device may not be able to obtain HARQ when transmitting HARQ and SR. As a result, the target PUCCH transmission fails. Therefore, in the embodiment of the present application, the symbol difference between the first symbol corresponding to the first PUCCH and the second symbol corresponding to the second PUCCH may be set to be less than or equal to a preset value. Exemplarily, the preset value may be defined in advance or configured by high-level signaling, and its value may be 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 or 14.

Among them, the first symbol can be the start symbol of the first PUCCH resource, it can also be the end symbol, or some symbol in the middle, such as the first symbol after frequency hopping, and the second symbol can be the second PUCCH. The start symbol of the resource can also be the end symbol, or an intermediate symbol, such as the first symbol after frequency hopping.

Exemplarily, if the first symbol is the start symbol of the first PUCCH resource and the second symbol is the start symbol of the second PUCCH resource, in one implementation manner, the symbol difference between the first symbol and the second symbol It can be equal to 0, that is, the first symbol and the second symbol are the same.

In addition, the first symbol corresponding to the first PUCCH may be before the second symbol corresponding to the second PUCCH, or may be after the second symbol corresponding to the second PUCCH.

Optionally, the symbol difference between the first symbol corresponding to the first PUCCH and the second symbol corresponding to the second PUCCH is greater than or equal to the first capability time. The first capability time is the minimum distance from the end symbol of the downlink data channel corresponding to HARQ to the start symbol of the second PUCCH resource corresponding to HARQ.

Specifically, since the terminal device needs a certain amount of preparation time from demodulating the downlink data channel to feeding back the corresponding HARQ, if HARQ is transmitted on the resources of the SR, if the first PUCCH corresponding to the SR is before the second PUCCH corresponding to the HARQ, it may be possible This will cause the HARQ transmission time to advance, so that the symbol difference between the first symbol corresponding to the first PUCCH and the second symbol corresponding to the second PUCCH is less than the first ability time of the terminal device to process downlink data, that is, the terminal device still HARQ information is not ready. In order to solve this problem, in the embodiment of the present application, the symbol difference between the first symbol corresponding to the first PUCCH corresponding to the SR and the second symbol corresponding to the second PUCCH corresponding to HARQ may be set to be greater than or equal to that of the terminal device processing downlink data The first capability time, where the first capability time for the terminal device to process downlink data is: the minimum distance from the end symbol of the downlink data channel corresponding to HARQ to the start symbol of the second PUCCH resource corresponding to HARQ. In this way, it can be guaranteed that HARQ and SR can be transmitted correctly.

The first symbol corresponding to the first PUCCH may be the start symbol corresponding to the first PUCCH, and the second symbol corresponding to the second PUCCH may be the end symbol corresponding to the second PUCCH. Of course, the first symbol and the second symbol may also be other symbols.

In a possible implementation manner, after determining the transmit power of the target PUCCH, the terminal device may use the transmit power to transmit the target PUCCH, that is, step 204 is performed.

Step 204: The terminal device sends the target PUCCH to the network device according to the transmit power of the target PUCCH.

Step 205: The network device determines the PUCCH resource corresponding to the target PUCCH, where the PUCCH resource includes the PRB index where the target PUCCH is located and/or sequence information corresponding to the target PUCCH.

In this step, when the terminal device sends the target PUCCH, if the PRB index is offset and/or the sequence information is changed according to the configuration of the higher-layer signaling or the predefined value, the network device is receiving the target PUCCH At this time, it is necessary to first determine the PRB index where the target PUCCH is located and/or the sequence information corresponding to the target PUCCH according to the configuration value or the predefined value, so as to determine the PUCC resource corresponding to the target PUCCH.

Step 206: The network device receives the target PUCCH on the PUCCH resource, the target PUCCH corresponds to one PUCCH set of the at least two PUCCH sets, and there is a correspondence between the at least two PUCCH sets and the at least two PUCCH transmission power parameters.

In this step, after determining the PUCCH resource corresponding to the target PUCCH, the network device will receive the target PUCCH on the PRB index where the target PUCCH is located and/or the sequence information corresponding to the target PUCCH.

In the communication method provided by the embodiment of the present application, the terminal device obtains at least two PUCCH transmit power parameters, and the at least two PUCCH transmit power parameters have a corresponding relationship with at least two PUCCH sets, and determine the target PUCCH according to the target PUCCH and the corresponding relationship. Corresponding PUCCH transmission power parameter, the target PUCCH corresponds to one PUCCH set of at least two PUCCH sets, and the transmission power of the target PUCCH is determined according to the PUCCH transmission power parameter corresponding to the target PUCCH. Since each PUCCH set in the at least two PUCCH sets corresponds to a different service type, and the target PUCCH corresponds to one PUCCH set in the at least two PUCCH sets, the terminal device can determine according to the target PUCCH corresponding to the service type The PUCCH transmission power parameter corresponding to the target PUCCH is then determined to determine the transmission power of the target PUCCH. In this way, when the terminal device has different types of services at the same time, the service can be determined according to the service type, for example, different service types correspond to different PUCCH sets. The corresponding PUCCH transmit power can satisfy the reliability requirements of different services.

In each of the foregoing embodiments, the aforementioned terminal device has first capability information, and the first capability information is at least one of capability information: capable of transmitting at least two types of services, capable of supporting at least two PUCCH sets, and capable of supporting at least The UCI corresponding to the two service types is transmitted in the same PUCCH, can support at least two PUCCH sets corresponding to the UCI information to be transmitted in the same uplink channel, can support at least two PUCCH transmission power parameters and at least two PUCCH sets correspond relationship. Furthermore, the terminal device may be able to obtain at least two physical uplink control channel PUCCH transmission power parameters, and determine the PUCCH transmission power parameter corresponding to the target PUCCH, thereby determining the transmission power of the target PUCCH.

Exemplarily, if the terminal device has the first capability information, the terminal device may send a third message to the network device, where the third message is used to indicate that the terminal device has the first capability information.

Exemplarily, if the terminal device does not have the first capability information, a fourth message may also be sent to the network device, where the fourth message is used to indicate that the terminal device does not have the first capability information.

Exemplarily, the network device may send a fifth message to the terminal device, where the fifth message is used to instruct to configure the first capability information for the terminal device. It should be understood that the network device may send the first configuration information to the terminal device based on the first capability information reported by the terminal device, or not based on the first capability information reported by the terminal device (or when the terminal device does not report the first capability information) ) Send the fifth message to the terminal device.

Exemplarily, the terminal device may not report a message indicating whether the first capability information is available to the network device. The network device will choose to configure the first capability information for the terminal device according to the actual situation, or choose not to be the terminal device Configure the above-mentioned first capability information.

Exemplarily, when the terminal device does not have the foregoing first capability information, the terminal device will not execute the method of the terminal device in the foregoing embodiments.
