Description

Communication method, communication apparatus, and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a communication method, a communication apparatus, and a storage medium.

Background

In order to cope with explosive mobile data traffic growth, device connection of mass mobile communication, and various new services and application scenarios that are continuously emerging in the future, a fifth Generation (5th Generation, 5G) mobile communication system has been produced. The International Telecommunications Union (ITU) defines three broad classes of application scenarios for 5G and future mobile communication systems: enhanced Mobile Broadband (eMBB), high-reliability Low-Latency Communications (URLLC), and Massive Machine-Type Communications (mMTC).

Because the reliability requirements of the eMBB service and the URLLC service are different, where the reliability requirement of the eMBB service is 90%, and the reliability requirement of the URLLC service is 99.9999%, when a terminal device has different types of services at the same time, how to determine the transmission power of a Physical Uplink Control Channel (PUCCH) corresponding to the services so as to meet the reliability requirements of the different services is a technical problem to be solved urgently at present.

Disclosure of Invention

The embodiment of the application provides a communication method, a communication device and a storage medium, which can determine the transmitting power corresponding to a PUCCH according to the service type, thereby meeting the requirements of different services on reliability.

In one aspect, an embodiment of the present application provides a communication method, which is applicable to a terminal device, and the method includes: acquiring at least two PUCCH (physical uplink control channel) transmitting power parameters, wherein the at least two PUCCH transmitting power parameters have a corresponding relation with at least two PUCCH sets, and determining PUCCH transmitting power parameters corresponding to a target PUCCH according to the target PUCCH and the corresponding relation; the target PUCCH corresponds to one PUCCH set in the at least two PUCCH sets, and the transmitting power of the target PUCCH is determined according to the PUCCH transmitting power parameter corresponding to the target PUCCH.

In this embodiment, each PUCCH set of the at least two PUCCH sets corresponds to a different service type, and the target PUCCH corresponds to one PUCCH set of the at least two PUCCH sets, so that the terminal device may determine a PUCCH transmit power parameter corresponding to the target PUCCH according to the target PUCCH corresponding to the service type, and further determine the transmit power of the target PUCCH.

In one possible design, the at least two PUCCH sets include a first PUCCH set and a second PUCCH set, or the at least two PUCCH sets include the first PUCCH set, the second PUCCH set, and a third PUCCH set, which is one of the at least two PUCCH sets other than the first PUCCH set and the second PUCCH set.

For example, each of the at least two PUCCH sets includes at least one PUCCH, and each PUCCH set may correspond to one traffic type. Specifically, the target PUCCH corresponds to the first PUCCH set, the first PUCCH set corresponds to the first PUCCH, the first PUCCH corresponds to first uplink control information UCI included in the target PUCCH, the second PUCCH set corresponds to the second PUCCH, and the second PUCCH corresponds to second UCI included in the target PUCCH. In this embodiment, the target PUCCH corresponds to the first PUCCH set, which may be understood as that the target PUCCH is included in the first PUCCH set, or may be understood as that the information type, transmission mode, or time-frequency resource corresponding to the target PUCCH is the same as that of the first PUCCH set. In the above design, when the terminal device transmits different types of services at the same time, the transmission power of the target PUCCH corresponding to the service may be determined according to the service type corresponding to the PUCCH, for example, a set of different PUCCH corresponding to different service types, so that the requirements of different services on reliability may be met.

In a possible implementation manner, the target PUCCH corresponds to the third PUCCH set, the first PUCCH set corresponds to a first PUCCH, the first PUCCH corresponds to first UCI included in the target PUCCH, the second PUCCH set corresponds to a second PUCCH, and the second PUCCH corresponds to second UCI included in the target PUCCH. In this embodiment, when a third PUCCH set is further included in the 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 third PUCCH set, and at this time, the transmission power of the target PUCCH is determined according to the transmission power parameter corresponding to the third PUCCH set. And the PUCCH in the third PUCCH set simultaneously carries information corresponding to the URLLC service and the eMBB service. In the above design, when the terminal device transmits different types of services at the same time, the transmission power of the target PUCCH corresponding to the service may be determined according to the service type corresponding to the PUCCH, for example, a set of different PUCCH corresponding to different service types, so that the requirements of different services on reliability may be met.

In a possible design, the first UCI is a scheduling request SR, the second UCI is a hybrid automatic repeat request HARQ, the formats of the first PUCCH and the second PUCCH are PUCCH format 0, and the target PUCCH is a PUCCH on a PRB where the first PUCCH is located. In this embodiment, the transmission power parameter of the target PUCCH is determined according to the transmission power parameter corresponding to the SR, and the target PUCCH is sent on the first PUCCH corresponding to the SR by using the transmission power corresponding to the SR. In the above design, since the transmission power parameter corresponding to the target PUCCH is determined according to the transmission power parameter corresponding to the SR on the PUCCH resource corresponding to the SR, compared with the determination of the transmission power parameter corresponding to the target PUCCH according to the transmission power parameter corresponding to the HARQ of the eMBB service in the prior art, the transmission reliability of the SR of the URLLC service can be ensured in this embodiment.

In another possible design, the first UCI is SR, the second UCI is HARQ, the target PUCCH is a PUCCH on the first PRB, and the index of the first PRB is an index value obtained by offsetting the index of the PRB where the second PUCCH is located by the first value.

In this embodiment, since the target PUCCH is one PUCCH on the PRB obtained after the index of the PRB where the second PUCCH corresponding to the HARQ is located deviates from the first value, it may be avoided that the URLLC SR transmission power is used on the second PUCCH resource of the eMBB HARQ, which may cause the phenomenon that the CS power is unbalanced on the PRB where the eMBB HARQ is located and the performance of other eMBB HARQ is degraded.

In the two possible designs, the sequence information corresponding to the target PUCCH and the sequence information corresponding to the first PUCCH have a corresponding relationship, or the sequence information corresponding to the target PUCCH and the sequence information corresponding to the second PUCCH have a corresponding relationship, or the sequence information corresponding to the target PUCCH and preset sequence information have a corresponding relationship.

In this embodiment, by performing sequence conversion on the sequence information corresponding to the target PUCCH, it is possible to avoid the phenomenon that power imbalance between CSs on the PRB where the eMBB HARQ is located and performance degradation of other eMBB HARQ occurs due to the use of URLLC SR transmission power on the second PUCCH resource of the eMBB HARQ.

In a possible design, 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 a second PRB, and the index of the second PRB is an index value obtained by offsetting the index of the PRB where the second PUCCH is located by a second value.

In this embodiment, the target PUCCH is set as one PUCCH on the PRB obtained after the index of the PRB where the second PUCCH is located is offset by the second value, so that the phenomenon that the performance of other eMBB HARQ is reduced due to the fact that the URLLC SR transmission power is used on the second PUCCH resource of the eMBB HARQ and power imbalance occurs between CSs on the PRB where the eMBB HARQ is located is avoided.

In one possible design, a symbol difference between a first symbol corresponding to the first PUCCH and a second symbol corresponding to the second PUCCH is smaller than or equal to a preset value, and/or the first PUCCH and the second PUCCH overlap in a time domain.

In this embodiment, since the terminal device needs preparation time from demodulation of the downlink data channel to feedback of the corresponding HARQ, if the SR is transmitted on the HARQ resource, if a time difference between the first PUCCH corresponding to the SR and the second PUCCH corresponding to the HARQ is greater than a preset value, the terminal device may fail to acquire information to be transmitted later, and thus the target PUCCH may be failed to be transmitted. Therefore, 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 smaller than or equal to a preset value, and/or the first PUCCH and the second PUCCH overlap in the time domain, so as to ensure transmission of the target PUCCH and improve the transmission success rate of the target PUCCH.

In one possible design, the target PUCCH corresponds to the first PUCCH set when a first condition is met, where the first condition includes at least one of: the format of downlink control information DCI corresponding to the target PUCCH is a first format; or scrambling a Radio Network Temporary Identifier (RNTI) of DCI corresponding to the target PUCCH as a first RNTI; or 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 a first search space; or the control resource set where the DCI corresponding to the target PUCCH is located belongs to a 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.

In another possible design, the target PUCCH corresponds to the second PUCCH set when the first condition is not satisfied.

In this embodiment, when the DCI format corresponding to the target PUCCH is the first format, the target PUCCH corresponds to the first PUCCH set. And when the format of the DCI corresponding to the target PUCCH is not the first format, and if the format of the DCI corresponding to the target PUCCH is the second format, the target PUCCH corresponds to the second PUCCH set. The first format may be DCI format 1_2, and the second format may be DCI format 1_0 or DCI format 1_ 1.

For example, when the RNTI of the DCI corresponding to the scrambling target PUCCH is the first RNTI, the target PUCCH corresponds to the first PUCCH set. And when the RNTI of the DCI corresponding to the scrambling target PUCCH is not the first RNTI, such as the second RNTI, the target PUCCH corresponds to the second PUCCH set. The first RNTI can be MCS-C-RNTI, and the second RNTI can be C-RNTI.

For example, 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 when the bit state of the first bit field in the DCI corresponding to the target PUCCH is not the first bit state, such as the second bit state, the target PUCCH corresponds to the second PUCCH set. The first bit field may be 1bit, the first bit state may be 0, and the second bit state may be 1.

For example, when the search space in which the DCI corresponding to the target PUCCH is located is the first search space, the target PUCCH corresponds to the first PUCCH set. And when the search space where the DCI corresponding to the target PUCCH is not the first search space, for example, the search space is the second search space, the target PUCCH corresponds to the second PUCCH set. The first search space may be a set of search spaces dedicated to the user, and the second search space may be a set of search spaces common to the user, or the first search space may also be a set of search spaces common to the user, and the second search space may be a set of search spaces dedicated to the user.

For example, when the index of the search space in which 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 when the index of the search space where the DCI corresponding to the target PUCCH is located does not belong to the first search space index group, if the index belongs to the second search space index group, the target PUCCH corresponds to the second PUCCH set.

For example, when the control resource set in which 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. And 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, if the DCI belongs to the second control resource set group, the target PUCCH corresponds to the second PUCCH set.

For example, when a scheduling request resource index (SR) corresponding to a scheduling request (scheduling request) carried by the target PUCCH belongs to the first scheduling request resource index set, the target PUCCH corresponds to the first PUCCH set. And 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, and if the scheduling request resource index belongs to the second scheduling request resource index set, the target PUCCH corresponds to the second PUCCH set.

In the above design, whether the target PUCCH corresponds to the first PUCCH set or the second PUCCH set is determined by determining whether the target PUCCH satisfies the first condition, so that efficiency of determining the PUCCH set corresponding to the target PUCCH can be improved.

In one possible design, obtaining at least two physical uplink control channel PUCCH transmit power parameters includes: receiving a first message indicating a target spatial correlation information index of a plurality of spatial correlation information indexes; and acquiring at least two PUCCH transmitting power parameters corresponding to the target space related information index.

In the above possible design, the obtaining at least two PUCCH transmit power parameters corresponding to the target spatial correlation information index includes: determining a target PUCCH transmitting power parameter index corresponding to the target space related information index; and determining at least two PUCCH transmission power parameters corresponding to the target PUCCH transmission power parameter index according to the corresponding relation between the target PUCCH transmission power parameter index and the plurality of PUCCH transmission power parameters.

In this embodiment, the network device configures a plurality of spatial correlation information indexes, for example, may configure at least two spatial correlation information indexes, for the terminal device in advance through the second message sent to the terminal device. The second message may be a Radio Resource Control (RRC) message or other higher layer signaling.

In addition, the first message may be an activation command sent by the network device through a Media Access Control (MAC) layer, and of course, the first message may also be other higher layer signaling.

In the above design, after the terminal device is configured with the multiple spatial correlation information indexes, the network device may send a first message to the terminal device to indicate a target spatial correlation information index in the multiple spatial correlation information indexes, so as to obtain at least two PUCCH transmit power parameters corresponding to the target PUCCH transmit power parameter index by determining the target PUCCH transmit power parameter index corresponding to the target spatial correlation information index, so as to configure at least two PUCCH transmit power parameters for activation of the terminal device, and when the terminal device simultaneously supports transmission corresponding to multiple different services, the terminal device may determine the PUCCH transmit power parameter to be used according to a currently transmitted service.

In another possible design, the obtaining at least two physical uplink control channel PUCCH transmit power parameters includes: acquiring a predefined target PUCCH transmission power parameter index; and acquiring at least two PUCCH transmission power parameters corresponding to the predefined target PUCCH transmission power parameter index according to the corresponding relation between the predefined target PUCCH transmission power parameter index and the plurality of PUCCH transmission power parameters.

In this embodiment, if the terminal device is not configured with the spatial correlation information index, the terminal device may directly obtain at least two PUCCH transmit power parameters corresponding to the predefined target PUCCH transmit power parameter index, so that the at least two PUCCH transmit power parameters may be obtained without interacting with the network device, which simplifies the obtaining process and improves efficiency.

On the other hand, an embodiment of the present application provides a communication method, which is applicable to a network device, and the method includes: determining PUCCH resources corresponding to a target Physical Uplink Control Channel (PUCCH), wherein the PUCCH resources comprise Physical Resource Block (PRB) indexes where the target PUCCH is located and/or sequence information corresponding to the target PUCCH; receiving the target PUCCH on the PUCCH resource, wherein the target PUCCH corresponds to one PUCCH set of at least two PUCCH sets; the at least two PUCCH sets have a corresponding relationship with at least two PUCCH transmission power parameters.

In this embodiment, the network device determines the PRB index where the target PUCCH is located and/or sequence information corresponding to the target PUCCH, and receives the target PUCCH on the PRB index where the target PUCCH is located and/or the sequence information corresponding to the target PUCCH. When the terminal device transmits different types of services at the same time, the transmitting power of the target PUCCH corresponding to the service can be determined according to the service types corresponding to the PUCCH, for example, the sets of different PUCCHs corresponding to different service types, so that the requirements of different services on reliability can be met.

In this embodiment, each of the at least two PUCCH sets includes at least one PUCCH, and each PUCCH set may correspond to one traffic type.

In one possible design, the target PUCCH corresponds to a first PUCCH set, the first PUCCH set corresponds to a first PUCCH, the first PUCCH corresponds to first uplink control information UCI included in the target PUCCH, the second PUCCH set corresponds to a second PUCCH, and the second PUCCH corresponds to second UCI included in the target PUCCH.

In this embodiment, the target PUCCH corresponds to the first PUCCH set, which may be understood as that the target PUCCH is included in the first PUCCH set, or may be understood as that the information type, transmission mode, or time-frequency resource corresponding to the target PUCCH is the same as that of the first PUCCH set.

In the above design, when the terminal device transmits different types of services at the same time, the transmission power of the target PUCCH corresponding to the service may be determined according to the service type corresponding to the PUCCH, for example, a set of different PUCCH corresponding to different service types, so that the requirements of different services on reliability may be met.

In a possible implementation manner, the target PUCCH corresponds to the third PUCCH set, the first PUCCH set corresponds to a first PUCCH, the first PUCCH corresponds to first UCI included in the target PUCCH, the second PUCCH set corresponds to a second PUCCH, and the second PUCCH corresponds to second UCI included in the target PUCCH.

In this embodiment, when a third PUCCH set is further included in the 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 third PUCCH set, and at this time, the transmission power of the target PUCCH is determined according to the transmission power parameter corresponding to the third PUCCH set. And the PUCCH in the third PUCCH set simultaneously carries information corresponding to the URLLC service and the eMBB service.

In a possible design, the first UCI is a scheduling request SR, the second UCI is a hybrid automatic repeat request HARQ, the formats of the first PUCCH and the second PUCCH are PUCCH format 0, and the target PUCCH is a PUCCH on a physical resource block PRB where the first PUCCH is located.

In this embodiment, the transmission power parameter of the target PUCCH is determined according to the transmission power parameter corresponding to the SR, and the target PUCCH is sent on the first PUCCH corresponding to the SR by using the transmission power corresponding to the SR.

In the above design, since the transmission power parameter corresponding to the target PUCCH is determined according to the transmission power corresponding to the SR on the PUCCH resource corresponding to the SR, compared with the determination of the transmission power parameter corresponding to the target PUCCH according to the transmission power parameter corresponding to the HARQ of the eMBB service in the prior art, the transmission reliability of the SR of the URLLC service can be ensured in this embodiment.

In one possible design, the method further includes: transmitting a first message indicating a target spatial correlation information index of a plurality of spatial correlation information indexes; there is a corresponding relationship between the target spatial correlation information index and the at least two PUCCH transmission power parameters.

Illustratively, the first message may be an activation command sent by the network device through a Media Access Control (MAC) layer, but of course, the first message may also be other higher layer signaling.

The eBB service and the URLLC service have different requirements on reliability, wherein the eBB service has a requirement on reliability of 90%, and the URLLC service has a requirement on reliability of 99.9999%. When the terminal device has both the URLLC service and the eMBB service, if the transmission power of the PUCCH corresponding to the eMBB service is adopted, the transmission reliability of the URLLC service may be reduced, resulting in a failure in URLLC service transmission. If the eMBB service is transmitted by adopting the transmitting power of the PUCCH corresponding to the URLLC service, the power waste of the terminal equipment can be caused, and the interference of the adjacent region can be increased. Therefore, when the 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 so as to meet the requirements of the different services on reliability is a technical problem to be solved by the embodiment of the present application.

In view of the above problems, in the embodiments of the present application, a communication method is provided, where a terminal device obtains at least two PUCCH transmission power parameters, where the at least two PUCCH transmission power parameters have a correspondence with at least two PUCCH sets, determines a PUCCH transmission power parameter corresponding to a target PUCCH according to a target PUCCH and the correspondence, where the target PUCCH corresponds to one PUCCH set of the at least two PUCCH sets, and determines transmission power of the target PUCCH according to the PUCCH transmission power parameter corresponding to the target PUCCH. Each PUCCH set of the at least two PUCCH sets corresponds to different service types, and the target PUCCH corresponds to one PUCCH set of the at least two PUCCH sets, so that the terminal equipment can determine PUCCH transmitting power parameters corresponding to the target PUCCH according to the target PUCCH corresponding to the service types, and further determine transmitting power of the target PUCCH.

The technical solution of the present application will be described in detail below with reference to specific examples. It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

It should be noted that, in the embodiments of the present application, the PUCCH is taken as an example for description, and in practical applications, other uplink channels may also be used, such as a Physical Uplink Shared CHannel (PUSCH) or a Sounding Reference Signal (SRS) cHannel, and for the power determination manners of other uplink channels, the power determination manners are similar to those of the PUCCH, and are not described herein again.

Fig. 2 is a signaling interaction diagram of the communication method of the present application. The present embodiment is described in terms of information interaction between a terminal device and a network device in a communication system. On the basis of 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 equipment acquires at least two PUCCH transmission power parameters, and the at least two PUCCH transmission power parameters and at least two PUCCH sets have corresponding relations.

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

In this step, the transmission power of the PUCCH may be determined according to formula (1):

wherein, P_PUCCH,b,f,cB is a partial Bandwidth (BWP) partial transmission bandwidth index, f is a carrier index, c is a serving cell, i is a transmission period of the PUCCH, q is a transmission power of the PUCCH in the serving cell, and b is a transmission bandwidth index of the PUCCH_uFor the initial PUCCH transmission power index, μ is a subcarrier spacing, where μ -0 represents a subcarrier spacing of 15Khz, μ -1 represents a subcarrier spacing of 30Khz, μ -2 represents a subcarrier spacing of 60Khz, μ -3 represents a subcarrier spacing of 120Khz, μ -4 represents a subcarrier spacing of 240Khz, and q is a subcarrier spacing of q_dFor reference signal resource index, l is power control adjustment state index, P_CMAX,,f,cMaximum power, P, allowed to be transmitted on carrier and serving cell for terminal equipment_{O_PUCCH,b,f,c}In order to transmit power for the initial PUCCH,

is the frequency domain bandwidth, PL, of the current PUCCH resource_b,f,c(q_d) Is a value of path loss, Δ_TF,b,f,c(i) Adjusting element for PUCCH transmission power, g_b,f,cThe state is adjusted for closed loop power control.

As can be seen from formula (1), 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}Wherein P is_{O_PUCCH,b,f,c}Is equal to P_{O_NOMINAL_PUCCH}And P_{O_UE_PUCCH}(q_u) And, P_{O_NOMINAL_PUCCH}Initial transmit power, P, for cell target PUCCH_{O_UE_PUCCH}(q_u) The target PUCCH initial transmit power is dedicated to the user.

Wherein, P_{O_UE_PUCCH}(q_u) Associated with the target initial PUCCH transmission power parameter (p0-PUCCH-Value values), there is a correspondence between the target initial PUCCH transmission power parameter and the target initial PUCCH transmission power parameter index (p0-PUCCH-Id index), which in turn has a correspondence with the spatial correlation information index (spatial correlation information Id).

Further, PL_b,f,c(q_d) In association with the target reference signal parameters (reference signal values), there is a correspondence between the target reference signal parameters and the target PUCCH path loss reference signal parameter index (PUCCH-pathloss reference rs-Id), which in turn has a correspondence with the spatial correlation information index (spatial correlation information Id).

Based on this, in practical application, the terminal device may obtain at least two PUCCH transmit power parameters through the spatial correlation information index indicated by the network device or the predefined target PUCCH transmit power parameter index to determine P_{O_UE_PUCCH}(q_u) And/or PL_b,f,c(q_d) And calculating the transmission power of the target PUCCH.

In a possible implementation manner, the terminal device may be configured with a plurality of spatial correlation information indexes in advance, and then the network device may send a first message to the terminal device, where the first message is used to indicate a target spatial correlation information index in the plurality of spatial correlation information indexes, and the terminal device will obtain at least two PUCCH transmit power parameters corresponding to the target spatial correlation information index. It is understood that the first message may be an activation command sent by the network device through a Media Access Control (MAC) layer, and of course, the first message may also be other high-layer signaling. The target spatial correlation information index may be one or more spatial correlation information indexes.

Specifically, the network device configures a plurality of spatial correlation information indexes for the terminal device in advance through the second message sent to the terminal device, for example, at least two spatial correlation information indexes may be configured. The second message may be a Radio Resource Control (RRC) message or other higher layer signaling. Illustratively, when the terminal device is configured with a plurality of spatial correlation information indexes, the terminal device obtains a first corresponding relationship, where the first corresponding relationship is a corresponding relationship existing between one PUCCH transmission power parameter set and one spatial correlation information index set. For example, the terminal device determines the first corresponding relationship by at least one PUCCH transmission power parameter index. It is understood that one PUCCH transmission power parameter index includes a first correspondence relationship in which at least two PUCCH transmission power parameters and one spatial correlation information index exist, or one PUCCH transmission power parameter index includes a first correspondence relationship in which one PUCCH transmission power parameter and one spatial correlation information index exist.

In this embodiment, the higher layer signaling may refer to signaling sent by a higher layer protocol layer, where the higher layer protocol layer is at least one protocol layer above a physical layer. The higher layer protocol layer may specifically include at least one of the following protocol layers: a Medium Access Control (MAC) layer, a Radio Link Control (RLC) layer, a Packet Data Convergence Protocol (PDCP) layer, a Radio Resource Control (RRC) layer, a non-Access stratum (NAS) layer, and the like.

It should be noted that, when the network device configures a spatial correlation information index for the terminal device in advance through the second message sent to the terminal device, the terminal device may directly determine the spatial correlation information index as the target spatial correlation information index.

Further, when the terminal device obtains at least two PUCCH transmit power parameters corresponding to the target spatial correlation information index, the terminal device may determine the at least two PUCCH transmit power parameters corresponding to the target PUCCH transmit power parameter index by determining the target PUCCH transmit power parameter index corresponding to the target spatial correlation information index and according to a corresponding relationship between the target PUCCH transmit power parameter index and the plurality of PUCCH transmit power parameters.

Wherein, the target PUCCH transmission power parameter index comprises: 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.

For example, there is a corresponding relationship between the target spatial correlation information index and the target PUCCH transmission power parameter index, for example, one target spatial correlation information index may correspond to one target PUCCH transmission power parameter index, or multiple target spatial correlation information indexes correspond to one target PUCCH transmission power parameter index, or one target spatial correlation information index corresponds to multiple target PUCCH transmission power parameter indexes.

Implementation mode 1: the target spatial correlation information index may be a spatial correlation information index. One spatial correlation information index may correspond to one target PUCCH transmission power parameter index. The one target PUCCH transmission power parameter index may correspond to at least two PUCCH transmission power parameters. The terminal equipment determines at least two PUCCH transmission power parameters according to a target PUCCH transmission power parameter index.

Implementation mode 2: the target spatial correlation information index may be at least two spatial correlation information indexes. One spatial correlation information index may correspond to at least one target PUCCH transmission power parameter index. One target PUCCH transmission power parameter index may correspond to at least one PUCCH transmission power parameter. The terminal equipment determines at least two PUCCH transmission power parameters according to at least one target PUCCH transmission power parameter index. For example, in a case where one spatial correlation 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 transmission power parameters according to at least two spatial correlation information indexes. Or, for example, in a case that one spatial correlation information index corresponds to at least two target PUCCH transmission power parameter indexes, or one target PUCCH transmission power parameter index corresponds to at least two PUCCH transmission power parameters, the terminal device may determine the at least two PUCCH transmission power parameters according to the at least two spatial correlation information indexes, or may determine the at least two PUCCH transmission power parameters according to only one spatial correlation information index.

For another example, when one target spatial correlation information index corresponds to multiple target PUCCH transmission power parameter indexes, generally, the terminal device may select one of the target PUCCH transmission power parameter indexes according to a preset rule, for example, select a first target PUCCH transmission power parameter index from the multiple target PUCCH transmission power parameter indexes corresponding to the target spatial correlation information index.

Implementation mode 3: the target spatial correlation information index may be a spatial correlation information index. One spatial correlation information index may correspond to at least two target PUCCH transmission power parameter indexes. One target PUCCH transmission power parameter index may correspond to at least one PUCCH transmission power parameter. The terminal equipment determines at least two PUCCH transmission power parameters according to the at least two target PUCCH transmission power parameter indexes.

In addition, a corresponding relation also exists between the target PUCCH transmission power parameter index and the plurality of PUCCH transmission power parameters, and based on the corresponding relation, the terminal equipment can determine at least two PUCCH transmission power parameters corresponding to the target PUCCH transmission power parameter index from the plurality of PUCCH transmission power parameters after determining the target PUCCH transmission power parameter index corresponding to the target spatial correlation information index. And the terminal equipment acquires a second corresponding relation, wherein the second corresponding relation is the corresponding relation existing in the indexes of the plurality of PUCCH transmitting power parameters and the plurality of PUCCH transmitting power parameters. 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 foregoing manner, after the terminal device is configured with the multiple spatial correlation information indexes, the network device may send a first message to the terminal device to indicate a target spatial correlation information index in the multiple spatial correlation information indexes, so as to obtain at least two PUCCH transmit power parameters corresponding to the target PUCCH transmit power parameter index by determining a target PUCCH transmit power parameter index corresponding to the target spatial correlation information index, so as to activate and configure at least two PUCCH transmit power parameters for the terminal device, and when the terminal device simultaneously supports transmission corresponding to multiple different services, the terminal device may determine the used PUCCH transmit power parameter according to a currently transmitted service.

In another possible implementation manner, the terminal device may also obtain a predefined target PUCCH transmission power parameter index, and obtain at least two PUCCH transmission power parameters corresponding to the predefined target PUCCH transmission power parameter index according to a correspondence between the predefined target PUCCH transmission power parameter index and the plurality of PUCCH transmission power parameters. Specifically, if the terminal device is not configured with the spatial correlation information index, at this time, the terminal device obtains at least two PUCCH transmission power parameters from a plurality of PUCCH transmission power parameters having a correspondence relationship with a predefined target PUCCH transmission power parameter index.

In this embodiment, the at least two PUCCH transmission power parameters correspond to at least two PUCCH sets. For example, at least two PUCCH transmission power parameters have a one-to-one correspondence relationship with at least two PUCCH sets, or one of the at least two PUCCH transmission power parameters may correspond to m PUCCH sets of the at least two PUCCH sets, or n PUCCH transmission power parameters of the at least two PUCCH transmission power parameters may correspond to one PUCCH set of the at least two PUCCH sets, where m and n are integers greater than 1.

For example, the at least two PUCCH sets may include a first PUCCH set and a second PUCCH set, or the at least two PUCCH sets may include a first PUCCH set, a second PUCCH set, and a third PUCCH set, which is one of the at least two PUCCH sets other than the first PUCCH set and the second PUCCH set.

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

It may be understood 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. That is, the same PUCCH may not simultaneously correspond to the first PUCCH set and the second PUCCH set, or the same PUCCH may not simultaneously correspond to the first PUCCH set, the second PUCCH set, and the third PUCCH set. The PUCCH is different, and may be understood as PUCCH carrying different information types, such as different types of Uplink Control Information (UCI), where the UCI includes hybrid automatic repeat request (HARQ), Scheduling Request (SR), or Channel State Information (CSI); or the PUCCH being different may be understood as different ways of triggering PUCCH transmission, for example, the ways of triggering PUCCH transmission include at least one of PUCCH triggered by periodic transmission, PUCCH triggered by Downlink Control Information (DCI), PUCCH triggered by semi-persistent transmission, and PUCCH triggered by DCI configured in advance or higher layer signaling; alternatively, the PUCCHs are different, which is to be understood that time-frequency resources corresponding to the PUCCHs are different, for example, the time-frequency resources include at least one of a starting symbol, a terminating symbol, or an occupied symbol number of the PUCCHs.

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

Step 202: and the terminal equipment determines PUCCH transmitting power parameters corresponding to the target PUCCH according to the target PUCCH and the corresponding relation, wherein the target PUCCH corresponds to one PUCCH set in at least two PUCCH sets.

In this step, the target PUCCH corresponds to one PUCCH set of the at least two PUCCH sets, and the at least two PUCCH transmission power parameters have a corresponding relationship with the at least two PUCCH sets. Therefore, according to the corresponding relation 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.

For example, the target PUCCH corresponds to one of the at least two PUCCH sets, it may be understood that the target PUCCH is included in one of the at least two PUCCH sets, or one of the at least two PUCCH sets includes the target PUCCH, and it may also be understood that content carried by the target PUCCH or corresponding attributes are the same as that of one of the at least two PUCCH sets, for example, information type or transmission mode or time-frequency resources corresponding to the target PUCCH are the same as that of one of the at least two PUCCH sets. In a specific implementation process, which PUCCH set the target PUCCH corresponds to may be determined according to the following manner:

and when the first condition is not met, the target PUCCH corresponds to the second PUCCH set. Wherein the first condition includes at least one of: the format of the DCI corresponding to the target PUCCH is a first format, or a Radio Network Temporary Identity (RNTI) scrambling the DCI corresponding to the target PUCCH is a first RNTI, or a bit state of a first bit field in the DCI corresponding to the target PUCCH is a first bit state, or a search space in which the DCI corresponding to the target PUCCH is located is a first search space, or a control resource set in which the DCI corresponding to the target PUCCH is located belongs to a first control resource set group, or an index of the search space in which the DCI corresponding to the target PUCCH is located belongs to a first search space index group, or a scheduling request resource index carried by the target PUCCH and corresponding to the SR belongs to a first scheduling request resource index set.

The DCI corresponding to the target PUCCH may be understood as DCI triggering the target PUCCH to transmit, for example, a PUCCH indication field exists in the DCI, and the DCI indicates a time-frequency resource of the target PUCCH, so that the terminal device transmits the target PUCCH. For example, the DCI and the target PUCCH have a preset correspondence, and after receiving the DCI, the terminal device determines the target PUCCH according to the preset correspondence, and then transmits the target PUCCH.

Illustratively, the format of the DCI corresponding to the target PUCCH includes at least one of a format of DCI indicating a downlink data channel and a format of DCI triggering CSI. The DCI format indicating the downlink data channel is control information for indicating that the downlink channel corresponding to the HARQ is transmitted. The format of the DCI comprises any one of the following formats: DCI format 1_0, DCI format 1_1, or DCI format 1_2, but of course, other formats are also possible, and this embodiment is not limited herein.

And when the format of the DCI corresponding to the target PUCCH is the first format, the target PUCCH corresponds to the first PUCCH set. And when the format of the DCI corresponding to the target PUCCH is not the first format, and if 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, or 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 may also be any two of the three formats, the second format may be other formats besides the first format, and the specific forms of the first format and the second format are not limited herein.

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

For the format of the DCI triggering the CSI, it includes any one 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, which may be other formats, and this embodiment is not limited herein. The DCI format 0_0, the DCI format 0_1, and the DCI format 0_2 are used to indicate that an uplink channel transmits corresponding control information.

And when the format of the DCI corresponding to the target PUCCH is the first format, the target PUCCH corresponds to the first PUCCH set. And when the format of the DCI corresponding to the target PUCCH is not the first format, and if 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 or DCI format 0_ 1. Of course, the first format may also be other formats in the above six formats, the second format may be a format other than the first format, and the specific forms of the first format and the second format are not limited herein.

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. And the third PUCCH set is one PUCCH set except the first PUCCH set and the second PUCCH set in the at least two PUCCH sets.

Illustratively, for each Physical Downlink Control Channel (Physical Downlink Control Channel; for DCI carried by PDCCH, PUCCH scrambles Cyclic Redundancy Check (CRC) of DCI using RNTI, and terminal equipment can distinguish different DCIs by RNTI, the RNTI may 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 a Modulation and coding scheme cell RNTI (Modulation and coding scheme cell RNTI; MCS-C-RNTI), which may be other RNTIs, and the form of the RNTI is not limited in this embodiment.

When the RNTI of the DCI corresponding to the scrambling target PUCCH is the first RNTI, the target PUCCH corresponds to the first PUCCH set. And when the RNTI of the DCI corresponding to the scrambling 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 an MCS-C-RNTI, and the second RNTI may be a C-RNTI, and of course, the first RNTI and the second RNTI may also be RNTIs of other types, and the specific forms of the first RNTI and the second RNTI are not limited herein in this embodiment of the application.

Further, when the RNTI of the DCI corresponding to the scrambling 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.

Illustratively, one or more bit fields are included in the DCI, each bit field for indicating control information. The bit state of the first bit field in the DCI corresponding to the target PUCCH includes at least one of a bit state of the first bit field in the DCI indicating the downlink data channel and a bit state of the first bit field in the DCI triggering the CSI. 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 when the bit state of the first bit field in the DCI corresponding to the target PUCCH is not the first bit state, for example, when the bit state is the second bit state, the target PUCCH corresponds to the second PUCCH set. Alternatively, the first bit field may be 1bit, 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 may be determined that the target PUCCH corresponds to the third PUCCH set. For example: when the first bit field is 2 bits, the first bit state is 00, the second bit state is 01, and the third bit state and the fourth bit state are 10/11, that is, when the bit state of the first bit field in the DCI corresponding to the target PUCCH is the third bit state 10 or the fourth bit state 11, the target PUCCH corresponds to the third PUCCH set.

For example, a set of candidate PDCCHs that the terminal device can monitor is typically defined as a PDCCH search space set. Wherein, the type of the search space set (search space set) may include: a common search space set (common search space set) or a user-specific search space set (UE-specific search space set). The common search space set (common search space set) may in turn comprise: 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 set.

The search space where the DCI corresponding to the target PUCCH is located comprises at least one of the search space where the DCI indicating the downlink data channel is located and the search space where the DCI triggering the CSI is located. And when the search space where the DCI corresponding to the target PUCCH is located is a first search space, the target PUCCH corresponds to the first PUCCH set. And when the search space where the DCI corresponding to the target PUCCH is not the first search space, for example, the search space is the second search space, the target PUCCH corresponds to the second PUCCH set. Optionally, the first search space may be a set of search spaces dedicated to the user, and the second search space may be a set of search spaces common to the user, or the first search space may also be a set of search spaces common to the user, and the second search space may be a set of search spaces dedicated to the user. The embodiments of the present application are not limited herein with respect to the specific form of the first search space and the second search space.

Further, when the search space in which 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.

For example, when the index of the search space in which 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 when the index of the search space in which the DCI corresponding to the target PUCCH is located does not belong to the first search space index group, such as when the index belongs to the second search space index group, the target PUCCH corresponds to the second PUCCH set.

Further, when the index of the search space in which the DCI corresponding to the target PUCCH is located does not belong to the first search space index group or the second search space index group, it may be determined that the target PUCCH corresponds to the third PUCCH set.

Illustratively, DCI needs to be transmitted in a Control Resource Set (CORESET), which is configured by high-layer signaling. The control resource set includes physical resources of multiple Resource Element Groups (REGs), and one control resource set may occupy 1, 2, or 3 symbols in the time domain and one or more resource blocks in the frequency domain. One control resource set may contain a plurality of search spaces, one search space corresponding to at least one control resource set.

The control resource set where the DCI corresponding to the target PUCCH is located includes at least one of a control resource set where the DCI indicating the downlink data channel is located and a control resource set where the DCI triggering the CSI is located. And 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. And 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, if the DCI 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 does not belong to the first control resource set group or the second control resource set group, it may be determined that the target PUCCH corresponds to the third PUCCH set.

Exemplarily, a plurality of scheduling request resource index sets may be configured through a high-level signaling or a predefined manner, and when a scheduling request resource index corresponding to an SR carried by a target PUCCH belongs to a first scheduling request resource index set, the target PUCCH corresponds to the first PUCCH set; or 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, if the scheduling request resource index 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 either 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 noted that the first condition and/or the second condition may be configured through higher layer signaling or may be predefined.

For example, as a possible implementation manner, when determining which PUCCH set the target PUCCH corresponds to, the determination may also be performed according to identification information corresponding to the PUCCH and identification information of each PUCCH set. Specifically, each PUCCH set corresponds to one identification information, and the target PUCCH may also include the identification information of the PUCCH set. And when the identification information corresponding to the target PUCCH is determined to be the same as the identification information of the first PUCCH set, determining that the target PUCCH corresponds to the first PUCCH set. And if the identification information corresponding to the target PUCCH is the same as the identification information of the second PUCCH set, determining that the target PUCCH corresponds to the second PUCCH set.

Step 203: and the terminal equipment determines the transmitting power of the target PUCCH according to the PUCCH transmitting power parameter corresponding to the target PUCCH.

For example, it is assumed that the first PUCCH set is a set corresponding to URLLC traffic, and the second PUCCH set is a set corresponding to eMBB traffic. And if the target PUCCH corresponds to the first PUCCH set, determining the PUCCH transmitting power parameter corresponding to the target PUCCH as the PUCCH transmitting power parameter corresponding to the first PUCCH set. Thus, the determined transmission power of the target PUCCH is the transmission power corresponding to the URLLC service. And if the target PUCCH corresponds to the second PUCCH set, determining the PUCCH transmitting power parameter corresponding to the target PUCCH as the PUCCH transmitting power parameter corresponding to the second PUCCH set. Thus, the determined transmission power of the target PUCCH is the transmission power corresponding to the eMBB service. Therefore, the transmission power of the target PUCCH can be determined according to different service types.

Further, it is assumed that the target PUCCH includes SR of URLLC traffic and HARQ of eMBB traffic. For example, the first PUCCH corresponds to SR, the second PUCCH corresponds to HARQ, and since SR can use only PUCCH format 0 and PUCCH format 1, 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.

A first PUCCH bears an SR through a resource corresponding to PUCCH format 1, a second PUCCH bears an HARQ through a resource corresponding to PUCCH format 1, and if the SR is a positive SR (positive SR), the HARQ is sent on the resource of PUCCH format 1 where the SR is located by using the transmitting power corresponding to the HARQ; if the SR is a negative SR (negative SR), the HARQ information is transmitted on the resource of PUCCH format 1 where the HARQ is located using the transmission power corresponding to the HARQ. The network device may determine whether the current terminal device sends a positive SR or a negative SR by blindly detecting the positions of the first PUCCH resource and the second PUCCH resource. The positive SR indicates that the terminal device currently has a request for uplink data transmission, and the negative SR indicates that the terminal device currently has no request for uplink data transmission.

A first PUCCH bears SR through a resource corresponding to PUCCH format 0, a second PUCCH bears HARQ through a resource corresponding to PUCCH format 0, if the SR is positive SR (positive SR), the SR is sent by adopting the transmitting power corresponding to the HARQ on the resource of PUCCH format 0 where the HARQ is located, and meanwhile, sequence information corresponding to the second PUCCH is subjected to sequence transformation; if the SR is a negative SR (negative SR), the HARQ information is sent on the resource of the PUCCH format 0 where the HARQ is located by using the transmission power corresponding to the HARQ, and at this time, sequence conversion is not performed on the sequence information corresponding to the second PUCCH.

When sequence information corresponding to the second PUCCH is subjected to sequence transformation, and when HARQ is 1bit and SR is a positive SR, the terminal device may transform the sequence in the following manner: the sequence index corresponding to positive SR +1(ACK) is { initial sequence index +3}, and 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 may transform the sequence as follows: the sequence index corresponding to positive SR +00(NACK ) is { initial sequence index +1}, the sequence index corresponding to positive SR +01(NACK, ACK) is { initial sequence index +4}, the sequence index corresponding to positive SR +11(ACK ) is { initial sequence index +7}, and the sequence index corresponding to positive SR +11(ACK, NACK) is { initial sequence index +10 }. Illustratively, the initial sequence index may be configured by higher layer signaling.

As can be seen from the above, when the target PUCCH is transmitted with the transmission power corresponding to HARQ, if HARQ corresponds to the eMBB service, the transmission reliability of the SR of the URLLC service cannot be guaranteed.

The problem can be solved in the embodiment of the application in the following two ways:

in an implementation manner, the target PUCCH corresponds to a first PUCCH set, the first PUCCH set corresponds to a first Uplink Control Information (UCI) included in the target PUCCH, the first PUCCH set corresponds to a second PUCCH set, and the second PUCCH set corresponds to a second UCI included in the target PUCCH. The UCI generally includes: HARQ, SR, and CSI. HARQ includes Acknowledgement (ACK) and Negative Acknowledgement (NACK), where ACK represents that reception is successful and NACK represents that reception is failed. The SR includes a positive SR and a negative SR, the positive SR represents that the terminal device has a request for uplink data transmission at present, and the negative SR represents that the terminal device does not have a request for uplink data transmission at present. The CSI generally includes an information combination of one or more of Channel Quality Information (CQI), Rank Indicator (RI), Precoding Matrix Indicator (PMI), channel state information reference signal resource indicator (CRI), or measurement link configuration set information. The CSI reporting mode comprises aperiodic CSI, semi-persistent CSI and periodic CSI.

Specifically, when the first PUCCH corresponds to a first UCI included in the target PUCCH and the second PUCCH corresponds to a second UCI included in the target PUCCH, the target PUCCH corresponds to the first PUCCH set, and at this time, the transmission power of the target PUCCH is determined according to the transmission power parameter corresponding to the first PUCCH set.

Further, the first UCI may be HARQ, and the second UCI may be SR, where the first PUCCH set corresponding to the target PUCCH is a PUCCH set corresponding to the first PUCCH having a corresponding relationship with HARQ. In addition, the first UCI may be SR, and the second UCI may be HARQ, in which case, the first PUCCH set corresponding to the target PUCCH is a PUCCH set corresponding to the first PUCCH having a correspondence relationship with SR. The HARQ may be an HARQ corresponding to a URLLC service, or an HARQ corresponding to an eMBB service, and the SR may be an SR corresponding to the URLLC service, or an SR corresponding to the eMBB service.

For example, after determining that the transmission power of the target PUCCH is the transmission power corresponding to the first PUCCH set, it may further consider whether a parameter Transmission Power Control (TPC) command word in the downlink control information triggering the HARQ is valid, where the TPC command word may or may not be valid. The condition whether the TPC command word is valid or not may be set according to higher layer signaling or actual conditions.

In another implementation manner, the target PUCCH corresponds to a third PUCCH set, the first PUCCH set corresponds to the first PUCCH, the first PUCCH corresponds to first UCI included in the target PUCCH, the second PUCCH set corresponds to the second PUCCH, and the second PUCCH corresponds to second UCI included in the target PUCCH.

Specifically, when a third PUCCH set is further included in the at least two PUCCH sets, when the first PUCCH corresponds to a first UCI included in the target PUCCH and the second PUCCH corresponds to a second UCI included in the target PUCCH, the target PUCCH corresponds to the third PUCCH set, and at this time, the transmission power of the target PUCCH is determined according to the transmission power parameter corresponding to the third PUCCH set. And the PUCCH in the third PUCCH set simultaneously carries information corresponding to the URLLC service and the eMBB service.

Exemplarily, after determining that the transmission power of the target PUCCH is the transmission power corresponding to the third PUCCH set, at this time, the TPC command word in the downlink control information currently triggering HARQ is not valid.

In the 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, the target PUCCH is one PUCCH on a Physical Resource Block (PRB) where the first PUCCH is located.

Specifically, the first PUCCH corresponds to an SR of a URLLC service, the second PUCCH corresponds to an HARQ of an eMBB service, the first PUCCH carries the SR through a resource corresponding to PUCCH format 0, the second PUCCH carries the HARQ through a resource corresponding to PUCCH format 0, the target PUCCH is one PUCCH on a 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 the transmission power parameter of the target PUCCH may be determined according to the transmission power parameter corresponding to the SR according to a preset rule. At this time, the target PUCCH is transmitted on the first PUCCH corresponding to the SR with the transmission power corresponding to the SR.

Compared with the prior art in which the transmission power parameter corresponding to the target PUCCH is determined according to the transmission power parameter corresponding to the HARQ of the eMBB service, the transmission reliability of the SR of the URLLC service can be ensured in the embodiment of the application. In addition, if the first UCI is SR and the second UCI is HARQ, the target PUCCH is one PUCCH on the first PRB, and the index of the first PRB is an index value obtained by offsetting the index of the PRB where the second PUCCH is located by the first value.

Specifically, in order to avoid the phenomenon that the power of the CS is unbalanced on the PRB where the eMBB HARQ is located and the performance of other eMBB HARQ is reduced due to the use of the URLLC SR transmission power on the second PUCCH resource of the eMBB HARQ, in this embodiment of the present application, a Physical Resource Block (PRB) of the target PUCCH needs to be shifted. Assuming that the first PUCCH corresponds to an SR of a URLLC service and the second PUCCH corresponds to an HARQ of an eMBB service, no matter whether the first PUCCH bears the SR through a resource corresponding to PUCCH format 0 or the SR through a resource corresponding to PUCCH format 1, the second PUCCH bears the HARQ through a resource corresponding to PUCCH format 0 or the HARQ through a resource corresponding to PUCCH format 1, at this time, the target PUCCH is one PUCCH on a PRB obtained after an index of the PRB where the second PUCCH corresponding to the HARQ is located is shifted by a first value.

The first value is an integer, and the value may be configured through a high-level signaling, may also be predefined, and may also be notified through triggering downlink control information corresponding to the HARQ, where the first value may be, for example, -1, 2, or-2, and a specific value of the first value is not limited herein.

Optionally, in order to avoid the phenomenon that power imbalance occurs between CSs on a PRB where the eMBB HARQ is located and performance of other eMBB HARQ is reduced due to the fact that the URLLC SR transmission power is used on the second PUCCH resource of the eMBB HARQ, sequence change needs to be performed on sequence information corresponding to the target PUCCH in the embodiment of the present application. Specifically, sequence transformation may be performed on sequence information corresponding to the first PUCCH corresponding to the SR, where a step size of the sequence transformation may be predefined or configured through high-layer signaling. Illustratively, when HARQ is 1bit and SR is a positive SR, the terminal device may transform the sequence as follows: the sequence index corresponding to positive SR +1(ACK) is { initial sequence index +3}, and 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 may transform the sequence as follows: the sequence index corresponding to positive SR +00(NACK ) is { initial sequence index +1}, the sequence index corresponding to positive SR +01(NACK, ACK) is { initial sequence index +4}, the sequence index corresponding to positive SR +11(ACK ) is { initial sequence index +7}, and the sequence index corresponding to positive SR +11(ACK, NACK) is { initial sequence index +10 }. It can be understood that after sequence information corresponding to the first PUCCH corresponding to the SR is subjected to sequence transformation, sequence information corresponding to the target PUCCH will have a corresponding relationship with sequence information corresponding to the first PUCCH.

Optionally, when sequence information corresponding to the target PUCCH is subjected to sequence change, sequence information corresponding to the second PUCCH corresponding to the HARQ may be subjected to sequence transformation, or sequence transformation may be performed on preset sequence information, where a step size of the sequence transformation may be similar to a step size of the sequence information corresponding to the first PUCCH corresponding to the SR, and is not described here again. It can be understood that after performing sequence transformation on the sequence information corresponding to the second PUCCH corresponding to the HARQ, the sequence information corresponding to the target PUCCH will have a corresponding relationship with the sequence information corresponding to the second PUCCH, and after performing sequence transformation on the preset sequence information, the sequence information corresponding to the target PUCCH will have a corresponding relationship with the preset sequence information.

Illustratively, when HARQ is 1bit and SR is positive SR, the terminal device may perform sequence transformation in the following manner, in addition to transforming the sequence in the manner of { initial sequence index +3} and { initial sequence index +9 }: { 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 and SR is positive SR, in addition to the sequence transformation in the manner of { initial sequence index +1}, { initial sequence index +4}, { initial sequence index +7}, and { initial sequence index +11}, the sequence transformation may be performed in the following manner: { sequence index +0, sequence index +3, sequence index +6, sequence index +9}, { sequence index +2, sequence index +5, sequence index +8, sequence index +11 }. For example, the sequence index may be an initial sequence index, may be another predefined sequence index, may be a sequence index corresponding to the first PUCCH, and may be a sequence index corresponding to the second PUCCH.

When the target PUCCH is one PUCCH on a PRB obtained by offsetting the index of the PRB in which the second PUCCH corresponding to the HARQ is located by the first value, the initial sequence information corresponding to the first PUCCH may be used as the sequence information corresponding to the target PUCCH, or the initial sequence information corresponding to the second PUCCH may be used as the sequence information corresponding to the target PUCCH.

Illustratively, 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 one PUCCH on the second PRB, and the index of the second PRB is an index value obtained by offsetting the index of the PRB where the second PUCCH is located by the second numerical value.

Specifically, a first PUCCH corresponds to HARQ of an eMBB service, a second PUCCH corresponds to SR of a URLLC service, the first PUCCH is HARQ carried by a resource corresponding to PUCCH format 1, the second PUCCH is SR carried by a resource corresponding to PUCCH format 1, and at this time, the target PUCCH is one PUCCH on a PRB obtained after an index of the PRB where the second PUCCH corresponding to SR is located is shifted by a second value.

The second value is an integer, which may be configured through a high-level signaling, or predefined, or notified through triggering downlink control information corresponding to the HARQ, and the second value may be, for example, -1, 2, or-2, and the specific value of the second value is not limited herein in this embodiment of the application.

Optionally, a symbol difference between a first symbol corresponding to the first PUCCH and a second symbol corresponding to the second PUCCH is smaller than or equal to a preset value; and/or the first symbol corresponding to the first PUCCH precedes the second symbol corresponding to the second PUCCH or the first symbol corresponding to the first PUCCH follows the second symbol corresponding to the second PUCCH; and/or the first PUCCH and the second PUCCH have partial overlap or full overlap.

In addition, since the terminal device needs preparation time from the demodulation of the downlink data channel to the feedback of the corresponding HARQ, if the SR is transmitted on the HARQ resource, if the time difference between the first PUCCH corresponding to the SR and the second PUCCH corresponding to the HARQ is greater than the preset value, when the HARQ and the SR are transmitted, information that is transmitted later may not be obtained, resulting in a failure in transmission of the target PUCCH. For example: if the first PUCCH corresponding to the SR is before the second PUCCH corresponding to the HARQ, and the time difference between the first PUCCH and the second PUCCH is greater than the preset value, the terminal device may not obtain the HARQ when transmitting the HARQ and the SR, thereby causing failure in transmission of the target PUCCH. Therefore, in the embodiment of the present application, a symbol difference between a first symbol corresponding to the first PUCCH and a second symbol corresponding to the second PUCCH may be set to be less than or equal to a preset value. Illustratively, the preset value may be predefined or configured by high-layer signaling, and may be, for example, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, or 14.

The first symbol may be a starting symbol of the first PUCCH resource, or may be a terminating symbol, or may be a middle symbol, such as a first symbol after frequency hopping, and the second symbol may be a starting symbol of the second PUCCH resource, or may be a terminating symbol, or may be a middle symbol, such as a first symbol after frequency hopping.

For example, if the first symbol is a starting symbol of the first PUCCH resource and the second symbol is a starting symbol of the second PUCCH resource, in an implementation, a symbol difference between the first symbol and the second symbol may 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 precede the second symbol corresponding to the second PUCCH, or may follow the second symbol corresponding to the second PUCCH.

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

Specifically, since the terminal device needs a certain preparation time from the demodulation of the downlink data channel to the feedback of the corresponding HARQ, if the HARQ is transmitted on the SR resource, if the first PUCCH corresponding to the SR is before the second PUCCH corresponding to the HARQ, the time for transmitting the HARQ may be advanced, so that a symbol difference between the first symbol corresponding to the first PUCCH and the second symbol corresponding to the second PUCCH is smaller than a first capability time for the terminal device to process downlink data, that is, the terminal device does not prepare HARQ information at this time. In order to solve the problem, in this embodiment of the present application, a symbol difference between a first symbol corresponding to a first PUCCH corresponding to an SR and a second symbol corresponding to a second PUCCH corresponding to an HARQ is set to be greater than or equal to a first capability time for a terminal device to process downlink data, where the first capability time for the terminal device to process downlink data is: and the minimum distance from the terminal symbol of the downlink data channel corresponding to the HARQ to the starting symbol of the second PUCCH resource corresponding to the HARQ. In this way, correct transmission of HARQ and SR can be ensured.

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

In a possible implementation manner, after determining the transmission power of the target PUCCH, the terminal device may transmit the target PUCCH with the transmission power, that is, execute step 204.

Step 204: and the terminal equipment sends the target PUCCH to the network equipment according to the transmitting power of the target PUCCH.

Step 205: and the network equipment determines PUCCH resources corresponding to the target PUCCH, wherein the PUCCH resources comprise PRB indexes where the target PUCCH is located and/or sequence information corresponding to the target PUCCH.

In this step, when the terminal device transmits the target PUCCH, if the PRB index is shifted and/or the sequence information is converted according to the configuration of the high layer signaling or the predefined value, the network device needs to 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 when receiving the target PUCCH, so as to determine the PUCC resource corresponding to the target PUCCH.

Step 206: the network equipment receives a target PUCCH on PUCCH resources, the target PUCCH corresponds to one PUCCH set of at least two PUCCH sets, and the at least two PUCCH sets and the at least two PUCCH transmission power parameters have corresponding relations.

In this step, after determining the PUCCH resource corresponding to the target PUCCH, the network device receives 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 application, the terminal device determines the PUCCH transmission power parameter corresponding to the target PUCCH according to the target PUCCH and the corresponding relationship by acquiring at least two PUCCH transmission power parameters, and determines the transmission power of the target PUCCH according to the PUCCH transmission power parameter corresponding to the target PUCCH. Each PUCCH set of the at least two PUCCH sets corresponds to different service types, and the target PUCCH corresponds to one PUCCH set of the at least two PUCCH sets, so that the terminal equipment can determine PUCCH transmitting power parameters corresponding to the target PUCCH according to the target PUCCH corresponding to the service types, and further determine transmitting power of the target PUCCH.

In the foregoing embodiments, the terminal device has first capability information, where the first capability information is at least one of capability information: the method can transmit at least two service types, can support at least two PUCCH sets, can support UCI corresponding to at least two service types to be transmitted in the same PUCCH, can support UCI information corresponding to at least two PUCCH sets to be transmitted in the same uplink channel, and can support at least two PUCCH transmission power parameters to have corresponding relation with at least two PUCCH sets. And then the terminal equipment can obtain at least two PUCCH transmission power parameters and determine the PUCCH transmission power parameters corresponding to the target PUCCH, thereby determining the transmission power of the target PUCCH.

For example, 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.

For example, if the terminal device does not have the first capability information, a fourth message may 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.

For example, the network device may send a fifth message to the terminal device, where the fifth message is used to indicate that the first capability information is configured 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 may send the fifth message to the terminal device without the first capability information reported by the terminal device (or in a case that the terminal device does not report the first capability information).

For example, the terminal device may not report a message indicating whether the terminal device has the first capability information to the network device, and the network device may select to configure the first capability information for the terminal device or select not to configure the first capability information for the terminal device according to an actual situation.

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

Fig. 3 is a schematic structural diagram of a first communication device according to an embodiment of the present disclosure. The communication apparatus may be applied to the terminal device described above, and as shown in fig. 3, the communication apparatus may include: and a processing module 11.

The processing module 11 is configured to obtain at least two PUCCH transmit power parameters, where the at least two PUCCH transmit power parameters have a correspondence with at least two PUCCH sets, and determine a PUCCH transmit power parameter corresponding to a target PUCCH according to the target PUCCH and the correspondence; the target PUCCH corresponds to one PUCCH set in the at least two PUCCH sets;

For example, in another possible implementation manner of the embodiment of the present application, the sequence information corresponding to the target PUCCH and the sequence information corresponding to the first PUCCH have a corresponding relationship, or the sequence information corresponding to the target PUCCH and the sequence information corresponding to the second PUCCH have a corresponding relationship, or the sequence information corresponding to the target PUCCH and the preset sequence information have a corresponding relationship.

For example, in another possible implementation manner of the embodiment of the present application, 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 one PUCCH on the second PRB, and the index of the second PRB is an index value obtained by shifting the index of the PRB where the second PUCCH is located by a second value.

For example, in the foregoing various possible implementations of the embodiments of the present application, a symbol difference between a first symbol corresponding to the first PUCCH and a second symbol corresponding to the second PUCCH is smaller than or equal to a preset value, and/or there is an overlap between the first PUCCH and the second PUCCH in a time domain.

Illustratively, in the foregoing various possible implementations of the embodiments of the present application, the target PUCCH corresponds to the first PUCCH set when a first condition is satisfied, where the first condition includes at least one of:

the format of downlink control information DCI corresponding to the target PUCCH is a first format; or

The bit state of a first bit field in the DCI corresponding to the target PUCCH is a first bit state; or

A search space where DCI corresponding to the target PUCCH is located is a first search space; or

The control resource set where the DCI corresponding to the target PUCCH is belongs to a first control resource set group; or

The index of the search space where the DCI corresponding to the target PUCCH is located belongs to a first search space index group; or

And the scheduling request resource index corresponding to the SR carried by the target PUCCH belongs to the first scheduling request resource index set.

For example, in the foregoing possible implementation manner of the embodiment of the present application, when the first condition is not satisfied, the target PUCCH corresponds to the second PUCCH set.

Illustratively, with continuing reference to fig. 3, in yet another possible implementation of the embodiment of the present application, the apparatus further includes: a receiving module 12, wherein:

the receiving module 12 is configured to receive a first message, where the first message is used to indicate a target spatial correlation information index in a plurality of spatial correlation information indexes;

the processing module 11 is further configured to obtain at least two PUCCH transmit power parameters corresponding to the target spatial correlation information index indicated by the receiving module 12 receiving the first message.

It should be noted that the division of the modules of the above apparatus is only a logical division, and the actual implementation may be wholly or partially integrated into one physical entity, or may be physically separated. And these modules can be realized in the form of software called by processing element; or may be implemented entirely in hardware; and part of the modules can be realized in the form of calling software by the processing element, and part of the modules can be realized in the form of hardware. For example, the processing module may be a processing element separately set up, or may be implemented by being integrated in a chip of the apparatus, or may be stored in a memory of the apparatus in the form of program code, and a function of the processing module may be called and executed by a processing element of the apparatus.

As another example, these modules may be integrated together, implemented in the form of a system-on-a-chip (SOC).
