Description

Power control method and power control device

Technical Field

The present application relates to the field of wireless communication technologies, and in particular, to a power control method and a power control apparatus.

Background

Mobile communication technology has profoundly changed people's lives, but the pursuit of higher performance mobile communication technology has never stopped. 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 mass machine Type Communications (mtc).

Typical URLLC services are: the main characteristics of the applications of wireless control in industrial manufacturing or production processes, motion control of unmanned automobiles and unmanned airplanes, and haptic interaction such as remote repair and remote operation are that ultra-high reliability, low time delay, less transmission data volume and burstiness are required. Typical mtc services are: the intelligent power distribution automation system has the main characteristics of huge quantity of networking equipment, small transmission data volume and insensitivity of data to transmission delay, and the mMTC terminals need to meet the requirements of low cost and very long standby time. Typical eMBB services are: the services include ultra high definition video, Augmented Reality (AR), Virtual Reality (VR), and the like, and these services are mainly characterized by large transmission data volume and high transmission rate.

In a wireless communication system, a reference signal needs to be transmitted during uplink data transmission (e.g., from a terminal device to a network device) or downlink data transmission (e.g., from the network device to the terminal device). Before data decoding, a receiving end needs to perform channel estimation on a channel by using a reference signal, and then decoding is performed by removing the influence of a spatial channel on data by using a result of the channel estimation. For example, for uplink transmission, the following procedure is generally performed: if the scheduling is based on the dynamic scheduling, the network device sends Downlink Control Information (DCI) to the terminal device, where the DCI carries indication information indicating a length of a time domain resource, a frequency domain resource, a modulation mode, and the like occupied by a Physical Uplink Shared Channel (PUSCH). And after receiving the DCI, the terminal equipment transmits the PUSCH on the corresponding time-frequency resource according to the indication of the DCI. If the terminal equipment is based on the configuration authorization, the terminal equipment sends the PUSCH to the network equipment without receiving the DCI, and the terminal equipment can determine the time-frequency resource for transmitting the PUSCH according to the configuration information received in advance and transmit the PUSCH on the time-frequency resource. For example, for uplink transmission configured with grant type 1, the indication information of uplink transmission PUSCH is all configured by Radio Resource Control (RRC) signaling, and the terminal device transmits PUSCH on configured time-frequency resources; for the uplink transmission configured with the authorization type 2, part of the indication information for uplink transmission of the PUSCH is from the RRC signaling configuration, and part of the indication information is from the DCI activating the uplink transmission configured with the authorization type 2, and the terminal device activates the RRC signaling according to the DCI sent by the network device, determines the time-frequency resource configured by the RRC signaling, and transmits the PUSCH on the time-frequency resource. The terminal device may support both transmission modes, or only one of them.

No matter which transmission mode is adopted, the design of the current system ensures that a reference signal is necessarily accompanied when data (such as PUSCH) transmission is carried out each time, so that a receiving end can carry out channel estimation and data demodulation through the reference signal, but due to the existence of the reference signal, time-frequency resources for transmitting data are reduced.

Those skilled in the art have found in long-term research that how to reduce the transmission of the reference signal and ensure the demodulation performance of the receiving end is an unsolved problem.

To facilitate an understanding of the present application, relevant technical knowledge related to embodiments of the present application will be first introduced herein.

The NR system supports various time scheduling units, which may be one or more time domain symbols in length. The symbols are Orthogonal Frequency Division Multiplexing (OFDM) symbols, which may or may not use transform precoding. If switched precoding is used, the OFDM symbol may also be referred to as single carrier-frequency division multiplexing (SC-FDM). The NR system is composed of slots (slots), one slot including 14 symbols. The NR system supports multiple subcarrier intervals, and the time lengths corresponding to slots under different subcarrier intervals are different. For example, a slot corresponds to 1 ms when the subcarrier spacing is 15kHz, 0.5 ms when the subcarrier spacing is 30kHz, and 0.25 ms when the subcarrier spacing is 60 kHz. Since the number of symbols in one slot is 14 symbols at all times, the length of time corresponding to a symbol also varies with the subcarrier spacing.

The higher layer signaling may refer to signaling sent by a higher layer protocol layer, which is at least one protocol layer in each protocol layer above the physical layer. The higher layer protocol layer may specifically be 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, and a non-access stratum (NAS) layer. It should be noted that the higher layer signaling is generally equivalent to the configuration information, and for convenience and consistency of description, the configuration information is referred to as the configuration information in the present application, that is, the configuration information is the higher layer signaling. In particular, physical layer signaling or dynamic signaling is generally control information carried in Downlink Control Information (DCI).

The time-frequency domain resources include time domain resources and/or frequency domain resources. The frequency domain resource may be one or more Resource Blocks (RBs), or one or more Resource Elements (REs), or one or more carriers/cells, or one or more fractional Bandwidths (BWPs), or one or more RBs on one or more BWPs on one or more carriers, or one or more REs on one or more RBs on one or more BWPs on one or more carriers. The time domain resource may be one or more time slots or one or more symbols over one or more time slots. The symbol may be an Orthogonal Frequency Division Multiplexing (OFDM) symbol.

It should be noted that, when the terminal device sends an uplink channel, the uplink channel is a carrier for carrying uplink information, and the network device receives the channel and decodes information on the channel, instead of referring to a virtual channel, that is, a virtual propagation path in a physical space. All the related uplink channels in this application refer to bearers for carrying uplink information.

Before transmitting the uplink channel, the terminal device calculates transmission power corresponding to the uplink channel, and transmits the uplink channel using the calculated transmission power. For example, if the terminal device needs to send the PUSCH, the corresponding transmission power may be obtained by specifically calculating through the following formula:

wherein, b isTable BWP partial transmission bandwidth index, f carrier index, c serving cell index, i transmission timing of a PUSCH, i PUSCH transmission timing being characterized at different time instant, j initial PUSCH transmission power index, i different index corresponding to different initial PUSCH transmission power P_{O_PUSCH,b,f,c}(j) And a scaling factor alpha for different path losses_b,f,c(j)。q_dRepresents a reference signal resource index, and l represents a PUSCH power control adjustment state index. μ denotes a subcarrier spacing, μ ═ 0 denotes a subcarrier spacing of 15kHz, μ ═ 1 denotes a subcarrier spacing of 30kHz, μ ═ 2 denotes a subcarrier spacing of 60kHz, μ ═ 3 denotes a subcarrier spacing of 120kHz, and μ ═ 4 denotes a subcarrier spacing of 240 kHz. P _CMAX,f,c(i) Representing the maximum value of power to be transmitted by the configuration terminal device,

and representing the frequency domain bandwidth of the ith PUSCH resource, and taking the value as the number of one or at least two RBs. Alpha is alpha_b,f,c(j) The scaling factor representing the Path Loss (PL) may be one of {0,0.4,0.5,0.6,0.7,0.8,0.9,1 }. PL_b,f,c(q_d) Representative of path loss, PL_b,f,c(q_d) Reference signal power-higher layer configuration filtering (reference signal received power). Wherein the reference signal power is configured by higher layer signaling, and the Reference Signal Received Power (RSRP) is determined according to higher layer configured filtering of the reference serving cell. Delta_TF,b,f,c(i) Transmission offset, f, representing the ith PUSCH resource_b,f,cAnd (i, l) is the PUSCH power control adjustment state quantity.

For K_SWhen the content is equal to 1.25,

for K_SWhen equal to 0, Δ_TF,b,f,c(i) 0. If the PUSCH is transmitted on more than one layer, i.e. the resource block corresponding to the PUSCH is mapped to at least two layers, and the power of each layer is different, Δ_TF,b,f,c(i)＝0。

In particular for bearersThe PUSCH for the data information is used for the data information,

for a PUSCH carrying only Channel State Information (CSI) but no data,

wherein, C is an encoded code block corresponding to a data transport block carried by the PUSCH, and one transport block may carry at least two encoded code blocks. K _rIs the corresponding code bit size of the code block r.

The value of (A) is related to whether the PUSCH carries data or not, if the PUSCH carries data, the value of (B) is related to whether the PUSCH carries data or not, and if the PUSCH carries data, the PUSCH carries data

The value is 1; if only the control information is carried in the PUSCH and no data is carried, then

Wherein

Is the number of time domain symbols where the PUSCH resource is located,

the number of REs after the RE occupied by the demodulation reference signal (DMRS) and the phase tracking signal is removed from the frequency domain resources of one RB in the number of time domain symbols in which the PUSCH is located.

Q_mThe modulation order is one of 1,2,4,6,8 and 10, wherein 1 represents pi/2BPSK modulation, 2 represents QPSK modulation, 4 represents 16QAM modulation, and 6 represents 64QAM modulation8 is denoted as 256QAM modulation and 10 is denoted as 1024QAM modulation. R is the target coding rate and generally ranges from 30/1024 to 948/1024, wherein R and Q_mIt may be configured through higher layer signaling or notified in DCI. f. of_b,f,c(i, l) is a PUSCH power control adjustment state quantity, and a value is determined according to Transmission Power Control (TPC) in DCI, or is equal to 0. The PUSCH power control adjustment state quantity is divided into an accumulation mode and an absolute mode, and when the PUSCH power control adjustment state quantity is in the accumulation mode, f is _b,f,c(i, l) is the cumulative increase in the PUSCH power control adjustment state quantity corresponding to the PUSCH transmitted at the previous time, and when in absolute mode, then f_b,f,c(i, l) is determined according to the currently transmitted PUSCH corresponding TPC.

The current protocol provides that each time a data transmission is made, a reference signal must be accompanied. Referring to fig. 2, as shown in fig. 2, a terminal device needs to transmit two PUSCHs, i.e. PUSCH1 and PUSCH2, in one slot, PUSCH1 occupies 7 symbols in one slot, wherein a reference signal occupies one symbol, the first two PUSCHs 2 occupy 2 symbols in one slot, and the last PUSCH2 occupies 3 symbols in one slot, wherein a reference signal occupies one symbol. It can be seen that, regardless of whether PUSCH1 or PUSCH2 includes a reference signal, it is worth mentioning that data can also be transmitted on the symbol on which the reference signal is located (using different frequency domain resources). In addition, when the terminal device performs at least two mini-slot (mini-slot) PUSCH transmissions, i.e., a PUSCH is transmitted with a few symbols instead of a PUSCH transmitted with more symbols all the time, as shown in the PUSCH2 in fig. 2, if a reference signal is present in each PUSCH2 according to the current protocol, the overhead of the whole reference signal is increased, and the uplink system resource transmission efficiency is reduced.

If at least two PUSCHs transmit the same data or different data and the frequency domain resources occupied by several PUSCHs in the at least two PUSCHs are the same, the several PUSCHs can realize reference signal sharing, namely, some PUSCHs can not carry reference signals, so that the uplink system resource transmission efficiency and the data transmission reliability can be improved. Referring to fig. 3, as shown in fig. 3, a terminal device sends three PUSCHs, where frequency domain resources of the three PUSCHs are the same, and reference signal sharing can be achieved, where a first PUSCH carries a reference signal, and the second PUSCH does not carry the reference signal, and in this case, the reception and demodulation of the second PUSCH depend on the reference signal transmitted on the first PUSCH.

It should be understood that if reference signal sharing is to be implemented, that is, the PUSCH should be received and demodulated using reference signals on other PUSCHs, it is necessary to ensure that the phase information of the reference signal is the same as that of the PUSCH demodulated using the reference signal, which means that the terminal device needs to ensure that the transmission power during the period of transmitting the reference signal and the PUSCH is consistent, as shown in fig. 3, the terminal device needs to ensure that the transmission power of the first PUSCH is consistent with that of the last two PUSCHs, so that the phase information of the three PUSCHs sharing the reference signal can be the same.

When at least two PUSCHs share the reference signal, according to the calculation formula of the PUSCH transmission power, it can be known that some PUSCHs have the reference signal and some PUSCHs do not have the reference signal, so that N of the PUSCHs has the reference signal_REDifferent, the transmission power of the at least two PUSCHs is different, so that the phase information of the at least two PUSCHs cannot be guaranteed to be the same, and the demodulation performance of the PUSCHs is reduced.

In particular, to ensure that the transmit power of the PUSCH sharing the reference signal is the same, i.e. to ensure Δ_TF,b,f,c(i) Or K_SAgain, one possible implementation is to always make Δ_TF,b,f,c(i) 0, or K _S0. It should be noted that, in this way, the PUSCH cannot adjust its transmit power along with the change of the configured REs, that is, the transmit power of the PUSCH cannot be adaptively adjusted according to the time-frequency resource corresponding to the PUSCH. In addition, only one K can be configured on one BWP by one terminal device_STherefore, when the PUSCH is only used for carrying CSI (i.e. no data is carried on the PUSCH), the transmission performance of CSI cannot be guaranteed. It can be seen that there are significant disadvantages to this approach.

In order to solve the above problem, the present application provides a power control method, a related device, and a system, which can ensure that the transmission powers of uplink channels sharing a reference signal are consistent, improve the demodulation performance of the uplink channels, and improve the reliability of uplink channel transmission.

Referring to fig. 4, fig. 4 is a flowchart illustrating a method for power control according to an embodiment of the present application. The terminal device and the network device described in fig. 4 may correspond to the terminal device and the network device shown in fig. 1, respectively. As shown in fig. 4, the method includes, but is not limited to, the following steps:

s401: the terminal device sends the first capability information to the network device.

Specifically, the first capability information is used to indicate a capability of the terminal device supporting sending of at least two uplink channels.

For example, the uplink channel may be a PUSCH, a PUCCH, a Sounding Reference Signal (SRS) channel, or another uplink channel, which is not limited in this application.

S402: the network device sends the first configuration information to the terminal device.

Specifically, the network device may send the first configuration information to the terminal device after receiving the first capability information sent by the terminal device.

Further, the first configuration information is used to configure the terminal device to send at least two uplink channels.

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 first configuration information to the terminal device without based on the first capability information reported by the terminal device (or in a case that the terminal device does not report the first capability information).

The at least two uplink channels bear the same data and/or control information, and/or the two uplink channels comprise a first uplink channel and a second uplink channel, a time domain resource where the first uplink channel is located is not overlapped with a time domain resource where the reference signal is located in a time domain, and a time domain resource where the second uplink channel is located is overlapped with a time domain resource where the at least one reference signal is located in the time domain.

In this embodiment, the terminal device reports the first capability information to the network device, so that the network device can flexibly configure whether the terminal device transmits at least two uplink channels according to requirements, thereby flexibly adapting to at least two different scenarios.

S403: the network equipment sends the first indication information to the terminal equipment.

Specifically, the network device may send the first indication information to the terminal device after sending the first configuration information to the terminal device.

Specifically, the first indication information is used to indicate the terminal device to send at least two uplink channels, where the at least two uplink channels include a first uplink channel and a second uplink channel, a time domain resource where the first uplink channel is located is not overlapped with a time domain resource where the reference signal is located in a time domain, a time domain resource where the second uplink channel is located is overlapped with a time domain resource where the at least one reference signal is located in a time domain, the at least two uplink channels include a first uplink channel set, and the first uplink channel set includes at least one uplink channel in the first uplink channel and at least one uplink channel in the second uplink channel.

Further, the first indication information may be DCI or other information, and the reference signal may be an uplink reference signal, and specifically may be a demodulation reference signal (DMRS), a phase-tracking reference signal (PT-RS), a Sounding Reference Signal (SRS), or other reference signals, which is not limited in this application. In particular, the DMRS may include a PUSCH DMRS or a PUCCH DMRS.

It should be noted that, the time domain resource where the first uplink channel is located and the time domain resource where the reference signal is located are not overlapped in the time domain, which means that each symbol does not include the reference signal in the symbols included in the first uplink channel. Optionally, the time domain resource where the first uplink channel is located and the time domain resource where any one of the reference signals is located are not overlapped in a time domain. The time domain resource where the second uplink channel is located and the time domain resource where the at least one reference signal is located are overlapped in the time domain, which indicates that at least one symbol including the reference signal exists in the symbols included in the second uplink channel. If the time domain resource of the second uplink channel is completely overlapped with the time domain resource of the at least one reference signal in the time domain, it indicates that each symbol included in the second uplink channel includes the reference signal. If the time domain resource of the second uplink channel is partially overlapped with the time domain resource of the at least one reference signal in the time domain, it indicates that part of the symbols included in the second uplink channel include the reference signal, and part of the symbols do not include the reference signal.

It should be understood that, among the at least two uplink channels transmitted by the terminal device, only one uplink channel set (i.e., the first uplink channel set) may be included, or other uplink channel sets may be included in addition to the first uplink channel set, for example, the second uplink channel set and more uplink channel sets may also be included. In addition, other uplink channel sets may include only one or more uplink channels in the second uplink channel; one or more of the first uplink channels and one or more of the second uplink channels may also be included. The different uplink channel sets may be uplink channel sets corresponding to different identifiers, uplink channel sets corresponding to different transmission types, uplink channel sets corresponding to different frequency domain resources, uplink channel sets corresponding to different time slots, or uplink channel sets corresponding to different time-frequency resource lengths.

In a specific embodiment, when the first indication information is DCI, the terminal device further receives second configuration information sent by the network device before receiving the first indication information sent by the network device, where the second configuration information is used to configure at least one of a first DCI format, a first Radio Network Temporary Identity (RNTI), a first control resource set, a first search space, or a first search space index set.

The first DCI format is a DCI format corresponding to the DCI, where the first DCI format may be DCI format 1_0, DCI format 1_1, or DCI format 1_2, and the like, and the DCI of different DCI formats may carry different resources. The first RNTI is an RNTI for scrambling the DCI, and the first RNTI may be a system information RNTI (SI-RNTI), a temporary cell RNTI (TC-RNTI), a paging RNTI (paging-RNTI, P-RNTI), a cell RNTI (cell-RNTI, C-RNTI), a configured scheduling RNTI (CS-RNTI), a modulation and coding scheme cell RNTI (MCS-C-RNTI), and the like. The first control resource set group includes a control resource set where the DCI is located, the first search space index group includes an index of a search space where the DCI is located, the first search space is a search space where the DCI is located, and particularly, the first search space may be a common search space or a user-dedicated search space. 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.

It can be understood that the terminal device performs the sending process of the uplink channel of the shared reference signal only after receiving the second configuration information, and sends the uplink channel of the shared reference signal to the network device, so as to ensure that the network device can correctly demodulate the sent uplink channel, and ensure the reliability of uplink channel transmission.

In a specific embodiment, the at least two uplink channels satisfy at least one of the following conditions: the transmission blocks carried by the at least two uplink channels are the same; or, the time domain resources where two uplink channels exist in the at least two uplink channels have different starting symbol indexes; or, the time domain length of the time domain resource where the two uplink channels exist in the at least two uplink channels has different symbol numbers; or, the time domain resources where the two uplink channels are located are in the same time slot in the at least two uplink channels.

It can be understood that, at least two uplink channels meeting the above conditions may share the reference signal, so as to improve the uplink system resource transmission efficiency, so that when the terminal device sends the at least two uplink channels meeting the above conditions, the terminal device may execute a sending process corresponding to the uplink channels sharing the reference signal, and send the at least two uplink channels meeting the conditions with the same sending power, so as to ensure that the terminal device may share the demodulation reference signal, reduce the overhead of the demodulation reference signal, and improve the demodulation performance.

S404: the terminal equipment acquires first power information corresponding to the first uplink channel set, and determines the sending power of the uplink channel in the first uplink channel set according to the first power information.

Specifically, after receiving first configuration information sent by the network device, the terminal device obtains first power information corresponding to the first uplink channel set.

Further, the first power information may be a transmission offset Δ_TFOr modulation coding scheme offset K_SOr other parameters for determining the power of the first uplink channel. After acquiring the first power information, the terminal device may calculate the transmission power by using a corresponding method for calculating the transmission power (e.g., the method for calculating the transmission power of the PUSCH), and transmit all uplink channels in the first uplink channel set by using the transmission power, that is, the transmission power of all uplink channels in the first uplink channel set is the same, and further, the phase information of all uplink channels is the same, so that the condition when the reference signal is shared may be satisfied.

S405: the terminal equipment sends at least two uplink channels to the network equipment.

Specifically, the terminal device transmits the at least two uplink channels to the network device after determining the transmission power of the uplink channels in the first uplink channel set.

Further, if at least two uplink channels sent by the terminal device only include the first uplink channel set, the terminal device sends the at least two uplink channels by using the calculated sending power. If at least two uplink channels sent by the terminal device include other uplink channel sets in addition to the first uplink channel set, the terminal device may send the uplink channels in the first uplink channel set by using the sending power calculated by the first power information corresponding to the first uplink channel set, and may send the uplink channels in the other uplink channel sets by using the existing sending method, or may calculate the corresponding sending power by using the same method for the other uplink channel sets, and send the uplink channels in the uplink channel sets according to the calculated sending power method.

S406: and the network equipment receives the uplink channels in the first uplink channel set according to at least one reference signal in the second uplink channel in the first uplink channel set.

It should be noted that the first uplink channel set may include one or more uplink channels in the second uplink channels, that is, there may be multiple uplink channels including reference signals in the first uplink channel set, and the uplink channel in each of the second uplink channels may include one or more reference signals.

In particular, since the transmission powers of all uplink channels in the first uplink channel set are consistent, the phase information of all uplink channels is the same, when the network device receives and demodulates, all uplink channels in the first uplink channel set can be received and demodulated only by one reference signal, and the network device can arbitrarily select one of the uplink channels carrying the reference signal to acquire the reference signal carried by the uplink channel, and receive and demodulate by using the reference signal.

It is understood that the above example is described by taking an example in which step S403 is executed after step S401 and step S402, but in practical applications, step S403 may be executed simultaneously with step S401 and step S402, or step S403 may be executed before step S401 and step S402, and step S401 or step S402 may be used alone or step S401 and step S402 may be used in combination; step S403 may be directly executed without using step S401 and step S402, and this application is not particularly limited.

It should also be understood that steps S401 to S406 in the above method embodiments are merely schematic descriptions and generalizations, and should not be construed as being particularly limited, and steps involved may be added, subtracted or combined as needed.

In a specific embodiment of the present application, when acquiring first power information corresponding to a first uplink channel set, a terminal device needs to determine a target uplink channel, and determine first power information corresponding to the first uplink channel set according to the first power information corresponding to the target channel.

Specifically, the target uplink channel is at least one uplink channel in the at least two uplink channels, or the target uplink channel is at least one uplink channel in the first uplink channel set.

For example, in the embodiment of the present application, a target uplink channel is determined in any one of the following manners:

mode 1 for determining a target uplink channel:

in a specific embodiment, the target uplink channel is an uplink channel with the largest number of resource elements for carrying data in the at least two uplink channels.

Specifically, the terminal device selects, according to the first indication information, an uplink channel, which carries the largest number of resource elements of data, from the at least two channels as a target uplink channel. Number of resource elements N carrying data in uplink channel_REThe calculation method can use the above calculation method, that is, resource elements occupied by the reference signal are removed from the time-frequency domain resource where the uplink channel is located; other calculation methods, such as removing resource elements occupied by the reference signal and resource elements occupied by Uplink Control Information (UCI) from the time-frequency domain resource where an uplink channel is located, may also be used. This is not limited in this application.

It can be understood that, if the uplink channel with the largest number of resource elements for carrying data in the at least two channels is selected as the target uplink channel, it is determined that the first power information corresponding to the obtained first uplink channel set is smaller, that is, the first power information is finally calculatedThe transmission power corresponding to the first uplink channel set is small, and for example, if the uplink channel is PUSCH, as is clear from the above description, N is_REThe larger, the larger_TFThe smaller the transmission power is, which can reduce the power consumption of the terminal equipment and reduce the interference between the terminal equipments in the cells.

Mode 2 for determining a target uplink channel:

in a specific embodiment, the target uplink channel is an uplink channel with the largest number of resource elements for carrying data in the first uplink channel set.

Specifically, if the at least two uplink channels include at least two uplink channel sets, at this time, the terminal device may select the uplink channel with the largest number of resource elements for carrying data in the first uplink channel set as the target uplink channel. N is a radical of_REThe calculation method of (a) may be the same as the above calculation method, or may be another calculation method, which is not limited in this application.

It should be noted that, at this time, the determined target uplink channel is not necessarily the uplink channel with the largest number of resource elements for carrying data in the at least two uplink channels, but only the uplink channel with the largest number of resource elements in the first uplink channel set. For other uplink channel sets in the at least two uplink channels, the corresponding first power information may also be determined by the same method, and then the corresponding transmission power is determined, which is not described herein again.

It can be understood that, if the uplink channel with the largest number of resource elements for carrying data in the first uplink channel set is selected as the target uplink channel, it is determined that the obtained first power information corresponding to the first uplink channel set is smaller, that is, the finally calculated sending power corresponding to the first uplink channel set is smaller, which can reduce power consumption of the terminal device and reduce interference of the terminal device between cells.

Mode 3 for determining a target uplink channel:

in a specific embodiment, the target uplink channel is an uplink channel with the least number of resource elements for carrying data in the at least two uplink channels.

Specifically, the terminal device selects, according to the first indication information, an uplink channel with a minimum number of resource elements for carrying data in the at least two channels as a target uplink channel. N is a radical of _REThe calculation method of (a) may be the same as the above calculation method, or may be another calculation method, which is not limited in this application.

It can be understood that, if an uplink channel with the minimum number of resource elements for carrying data in at least two channels is selected as the target uplink channel, it is determined that the obtained first power information corresponding to the first uplink channel set is larger, that is, the finally calculated transmission power corresponding to the first uplink channel set is larger, for example, if the uplink channel is a PUSCH, as can be seen from the above description, N is_REThe smaller is, the_TFThe larger the transmission power is, the larger the transmission power obtained by final calculation is, so that the uplink channel can be ensured to be correctly received by the network equipment, and the reliability is improved.

Mode 4 for determining a target uplink channel:

in a specific embodiment, the target uplink channel is an uplink channel with the smallest number of resource elements for carrying data in the first uplink channel set.

Specifically, if the at least two uplink channels include at least two uplink channel sets, at this time, the terminal device may select the uplink channel with the smallest number of resource elements for carrying data in the first uplink channel set as the target uplink channel. N is a radical of _REThe calculation method of (a) may be the same as the above calculation method, or may be another calculation method, which is not limited in this application.

It should be noted that, at this time, the determined target uplink channel is not necessarily an uplink channel with the minimum number of resource elements for carrying data in at least two uplink channels to be sent, but is only an uplink channel with the maximum number of resource elements in the first uplink channel set. For other uplink channel sets in the at least two uplink channels, the corresponding first power information may also be determined by the same method, and then the corresponding transmission power is determined, which is not described herein again.

It can be understood that, if the uplink channel with the minimum number of resource elements for carrying data in the first uplink channel set is selected as the target uplink channel, it is determined that the obtained first power information corresponding to the first uplink channel set is larger, that is, the finally calculated transmission power corresponding to the first uplink channel set is larger, so that it can be ensured that the uplink channel carrying the reference signal can be correctly received by the network device, and reliability is improved.

Mode 5 for determining a target uplink channel:

in a specific embodiment, the target uplink channel is an uplink channel occupying the largest number of time domain symbols among the at least two uplink channels.

Specifically, the terminal device selects, according to the first indication information, an uplink channel occupying the largest number of time domain symbols in the at least two channels as a target uplink channel. Time domain symbol number occupied by uplink channel

The above definition can be used, that is, when the uplink channel is PUSCH,

for the number of time domain symbols occupied by PUSCH resources, other calculation methods may also be used, for example, a time domain symbol occupied by a resource element occupied by a reference signal is removed from a time domain symbol occupied by an uplink channel (suitable for some special transmission waveforms, such as strict separation of the reference signal and data in time due to conversion of a precoder). This is not limited in this application.

It can be understood that, if the uplink channel occupying the largest number of time domain symbols in the at least two uplink channels is selected as the target uplink channel, it is determined that the obtained first power information corresponding to the first uplink channel set is smaller, that is, the finally calculated transmission power corresponding to the first uplink channel set is smaller, for example, if the uplink channel is the PUSCH, as can be seen from the above description,

the larger, the larger_TFThe smaller the transmission power is, which can reduce the power consumption of the terminal equipment and reduce the interference between the terminal equipments in the cells.

Mode 6 for determining a target uplink channel:

in a specific embodiment, the target uplink channel is an uplink channel occupying the largest number of time domain symbols in the first uplink channel set.

Specifically, if the at least two uplink channels include at least two uplink channel sets, at this time, the terminal device may select the uplink channel occupying the largest number of time domain symbols in the first uplink channel set as the target uplink channel.

The calculation method may be the same as the above calculation method, or may be another calculation method, which is not limited in this application.

It should be noted that, at this time, the determined target uplink channel is not necessarily the uplink channel occupying the largest number of time domain symbols among at least two uplink channels to be transmitted, but is only the uplink channel occupying the largest number of resource elements in the first uplink channel set. For other uplink channel sets in the at least two uplink channels, the corresponding first power information may also be determined by the same method, and then the corresponding transmission power is determined, which is not described herein again.

It can be understood that, if the uplink channel occupying the largest number of time domain symbols in the first uplink channel set is selected as the target uplink channel, it is determined that the obtained first power information corresponding to the first uplink channel set is smaller, that is, the finally calculated transmission power corresponding to the first uplink channel set is smaller, which can reduce power consumption of the terminal device and reduce interference of the terminal device between cells.

Mode 7 for determining a target uplink channel:

in a specific embodiment, the target uplink channel is an uplink channel occupying the least number of time domain symbols among the at least two uplink channels.

Specifically, the terminal device selects, according to the first indication information, an uplink channel occupying the least number of time domain symbols in the at least two channels as a target uplink channel.

It can be understood that, if the uplink channel occupying the least number of time domain symbols in the at least two uplink channels is selected as the target uplink channel, it is determined that the obtained first power information corresponding to the first uplink channel set is larger, that is, the finally calculated transmission power corresponding to the first uplink channel set is larger, for example, if the uplink channel is the PUSCH, as can be seen from the above description,

the smaller is, the_TFThe larger the transmission power is, the larger the transmission power obtained by final calculation is, so that the uplink channel can be ensured to be correctly received by the network equipment, and the reliability is improved.

in a specific embodiment, the terminal device determines a second uplink channel of the at least two uplink channels as a target uplink channel, and determines first power information corresponding to the second uplink channel as first power information corresponding to the first uplink channel set.

It can be appreciated that since the second uplink channel includes a reference signal, N_RESmaller, the first power information is larger, i.e. Δ_TFIf the calculated transmission power is larger, the final calculated transmission power is also larger, so that the terminal equipment determines that the second uplink channel in the at least two uplink channels is the target uplink channel, the uplink channel can be ensured to be correctly received by the network equipment, and the reliability of the uplink channel is improved.

Mode 36 for determining target uplink channel:

In a specific embodiment, the terminal device determines a second uplink channel in the first uplink channel set as a target uplink channel, and determines first power information corresponding to the second uplink channel as first power information corresponding to the first uplink channel set.

Specifically, if the at least two uplink channels include at least two uplink channel sets, that is, in addition to the first uplink channel set, other uplink channel sets besides the first uplink channel set are also included. At this time, the terminal device may select a second uplink channel in the first uplink channel set as a target uplink channel, and determine first power information corresponding to the second uplink channel as first power information corresponding to the first uplink channel set.

It can be appreciated that since the second uplink channel includes a reference signal, N_RESmaller, the first power information is larger, i.e. Δ_TFIf the calculated transmission power is larger, the final calculated transmission power is also larger, so that the terminal equipment determines that the second uplink channel in the first uplink channel set is the target uplink channel, the uplink channel can be ensured to be correctly received by the network equipment, and the reliability of the uplink channel is improved.

It should be noted that, all the methods for determining a target uplink channel according to the foregoing embodiments may be used alone or in combination, and a specific combination manner is not limited in this application.

It should be understood that, in a possible implementation manner of the present application, the terminal device may also perform comprehensive judgment in combination with the above multiple manners, so as to ensure that an uplink channel is finally selected as the target uplink channel. The following is a detailed description of a method in combination of ways, which may include the following steps:

step one, the terminal equipment determines a candidate uplink channel according to the mode A;

step two A, if the candidate uplink channel comprises an uplink channel, the terminal equipment determines the candidate uplink channel as a target uplink channel.

Step two, if the candidate uplink channels comprise a plurality of uplink channels, the terminal equipment adopts a mode B to determine a new candidate uplink channel from the candidate uplink channels, wherein the mode A is different from the mode B, and if the new candidate uplink channel is one, the terminal equipment determines the candidate uplink channel as a target uplink channel; if there are multiple new candidate uplink channels, the step two B is repeatedly executed until the only target uplink channel is determined, and it is particularly emphasized that the method not used in the foregoing steps is adopted each time the step two B is executed, that is, each method is used only once to screen the candidate uplink channels, and after the step two B is used once, other methods not used are used to determine the target uplink channel when the step two B is executed again.

It should be understood that the manner a is different from the manner B, and both the manner a and the manner B may belong to any one of the 36 determination manners described above, but the present embodiment is not limited thereto.

For example, the terminal device may determine the target uplink channel according to the method 14 (that is, the terminal device determines that the uplink channel carrying the UCI in the at least two uplink channels is the target uplink channel). If the only target uplink channel cannot be determined, the terminal device may determine the target uplink channel from the candidate uplink channels determined in the manner 14 according to the manner 18 (the terminal device determines that the uplink channel corresponding to the highest priority for carrying the UCI in the first uplink channel set is the target uplink channel). If the only target uplink channel cannot be determined, the terminal device may determine the target uplink channel from the new candidate target uplink channels determined in the manner 18 according to the manner 26 (the terminal device determines, as the target uplink channel, the uplink channel with the lowest transmission code rate of the UCI in the uplink channels that simultaneously carry the UCI and the data in the first uplink channel set). It can be understood that the method 14, the method 18, and the method 26 are combined to determine the target uplink channel, which has the beneficial effects of the foregoing methods, that is, the determined target uplink channel can be ensured to be reliably received by the network device, and the network device can be ensured to effectively acquire the UCI with the highest priority in the target uplink channel, and at the same time, the performance of the uplink channel with the lowest transmission code rate of the UCI in the uplink channel carrying the UCI, the uplink channel corresponding to the highest priority carrying the UCI, and the uplink channel carrying the UCI and data at the same time is ensured.

For example, the terminal device may determine the target uplink channel according to the method 13 (that is, the terminal device determines that the uplink channel carrying the UCI in the at least two uplink channels is the target uplink channel). If the only target uplink channel cannot be determined, the terminal device may determine the target uplink channel from the candidate uplink channels determined in the manner 13 according to the manner 3 (that is, the terminal device determines the uplink channel with the smallest number of resource elements for carrying data in the at least two uplink channels as the target uplink channel). If the unique target uplink channel cannot be determined, the terminal device may determine the target uplink channel from the new candidate target uplink channels determined in the manner 3 according to the manner 17 (that is, the terminal device determines the uplink channel corresponding to the highest priority of the UCI carried in the at least two uplink channels as the target uplink channel). It can be understood that the method 13, the method 3, and the method 17 are combined to determine the target uplink channel, which has the beneficial effects of the foregoing methods, that is, the determined target uplink channel can be reliably received by the network device, the reliability of the uplink channel is improved, the network device can be ensured to effectively acquire the UCI with the highest priority in the target uplink channel, and at the same time, the uplink channel carrying the UCI, the uplink channel carrying the minimum number of resource elements of data, and the uplink channel carrying the uplink channel corresponding to the highest priority of the UCI are ensured.

For example, the terminal device may determine the target uplink channel according to the manner 36 (that is, the terminal device determines that the second uplink channel in the first uplink channel set is the target uplink channel). If the only target uplink channel cannot be determined, the terminal device may determine the target uplink channel from the candidate uplink channels determined in the manner 36 according to the manner 14 (that is, the terminal device determines the uplink channel carrying the UCI in the first uplink channel set as the target uplink channel). If the unique target uplink channel cannot be determined, the terminal device may determine the target uplink channel from the new candidate target uplink channels determined in the manner 14 according to the manner 18 (that is, the terminal device determines the uplink channel corresponding to the highest priority for carrying the UCI in the first uplink channel set as the target uplink channel). It can be understood that the method 36, the method 14, and the method 18 are combined to determine the target uplink channel, which has the beneficial effects of the foregoing methods, that is, the determined target uplink channel can be reliably received by the network device, the reliability of the uplink channel is improved, the network device can be ensured to effectively acquire the UCI with the highest priority in the target uplink channel, and meanwhile, the performance of the second uplink channel, the uplink channel carrying the UCI, and the uplink channel carrying the uplink channel corresponding to the highest priority of the UCI are ensured.

For example, the terminal device may determine the target uplink channel according to the method 34 (that is, the terminal device determines that the first uplink channel in the first uplink channel set is the target uplink channel). If the only target uplink channel cannot be determined, the terminal device may determine the target uplink channel from the candidate uplink channels determined in the manner 34 according to the manner 14 (that is, the terminal device determines the uplink channel carrying the UCI in the first uplink channel set as the target uplink channel). If the unique target uplink channel cannot be determined, the terminal device may determine the target uplink channel from the new candidate target uplink channels determined in the manner 14 according to the manner 18 (that is, the terminal device determines the uplink channel corresponding to the highest priority for carrying the UCI in the first uplink channel set as the target uplink channel). If the unique target uplink channel cannot be determined, the terminal device may determine the unique target uplink channel from the new candidate target uplink channels determined in the manner 18 according to the manner 2 (that is, the terminal device determines the uplink channel with the largest number of resource elements for carrying data in the first uplink channel set as the target uplink channel); or, according to the mode 30 (that is, the terminal device determines the uplink channel carrying the largest number of bits of the UCI in the first uplink channel set as the target uplink channel), determining a unique target uplink channel from the new candidate target uplink channels determined in the mode 18; or, according to the mode 28 (that is, the terminal device determines that the uplink channel with the highest or lowest transmission code rate of the data in the uplink channels that simultaneously carry the UCI and the data in the first uplink channel set is the target uplink channel), the only target uplink channel is determined from the new candidate target uplink channels determined in the mode 18. It is to be understood that by combining the above-described modes 34, 14, 18, and 2, or modes 34, 14, 18, and 30, or the manner 34, the manner 14, the manner 18 and the manner 28 to determine the target uplink channel, has the advantages of the foregoing manners, namely, the power consumption of the terminal equipment can be reduced, the interference of the terminal equipment among the regions can be reduced, the determined target uplink channel can be reliably received by the network equipment, the reliability of the uplink channel is improved, and ensures that the network equipment can effectively acquire the UCI with the highest priority in the target uplink channel, and simultaneously ensuring the performance of the first uplink channel, the uplink channel carrying the UCI, the uplink channel corresponding to the highest priority carrying the UCI, the uplink channel carrying the largest number of resource elements of the data, or the uplink channel carrying the largest number of bits of the UCI, or the uplink channel carrying the UCI and the data simultaneously and having the highest or the lowest transmission code rate of the data.

In a possible implementation manner, the manner for determining the target uplink channel (for example, the corresponding manner 1 to manner 36) may have a priority, that is, the terminal device may first use the information with higher priority in the determination manner to perform the determination, and if the information with higher priority cannot determine the only target uplink channel, the terminal device may then use the information with lower priority to perform the determination. It should be understood that the priority may be configured to the terminal device by pre-defined or by the network device through higher layer signaling configuration.

It can be seen that, by implementing any of the above embodiments, it can be ensured that the transmission powers of the uplink channels in the first uplink channel set are the same under the condition of reference signal sharing, the problem of reduced receiving performance caused by different uplink channels having different transmission powers when the reference signal is shared and the problem that the transmission power of the uplink channel cannot be adaptively adjusted are solved, the reliability of uplink channel transmission is improved, and the overhead of the reference signal is reduced.
