To facilitate understanding of the embodiments of the present application, several basic concepts involved in the embodiments of the present application are briefly described. It should be understood that the basic concepts introduced in the following are briefly described by taking the basic concepts specified in the NR protocol as an example, but it is not limited that the embodiments of the present application can only be applied to the NR system. Therefore, the standard names that appear when describing the NR system as an example are all functional descriptions. The specific names are not limited, but only represent the functions of the device, which can be extended to other systems, such as 4G or future communication systems.

1. PUSCH transmission:

In the NR communication system, PUSCH transmission supports two transmission schemes: codebook-based transmission and non-codebook-based transmission. The terminal device can perform channel measurement according to the sounding reference signal (sounding reference signal, SRS) sent by the network device. The network device configures one or more SRS resource sets for the terminal device through the SRS-ResourceSet (or other high-level parameters), and each SRS resource set contains parameter usages (for example, the parameter usages include: codebook, Non-codebook (nonCodebook), beam management (beamManagement) and antenna switching (antennaSwitching) are used to determine the function of the SRS resource set.

The above four parameter use cases correspond to four different functions respectively. Among them, codebook corresponds to codebook-based uplink transmission, nonCodebook corresponds to non-codebook-based uplink transmission, beamManagement corresponds to beam management, and antennaSwitching corresponds to antenna switching. The network device obtains uplink (or downlink) channel information according to the received SRS, and performs data scheduling according to the channel information.

2. Uplink power control mechanism:

In the NR communication system, the 15th (release15, R15) protocol and the 16th (release16, R16) protocol stipulate that the calculation method of the transmit power of the PUSCH is as follows:

where:

P _CMAX,f,c (i) is the maximum transmit power configured by the terminal;

P _{O_PUSCH,b,f,c} (j) is the static working point of the base station;

Reflect the impact of PUSCH bandwidth on power;

PL _b,f,c (q _d ) is the downlink path loss;

α _{b, f, c} (j) is the path loss compensation factor;

ΔTF _,b,f,c (i) reflects the influence of code rate on transmit power;

f _{b, f, c} (i, l) is the power control adjustment amount introduced by the transmit power control (transmit power control, TPC) command.

The TPC field is used to indicate the power control adjustment of the uplink information, and the network device performs closed-loop adjustment of the power allocation based on the power control value indicated by the high-level parameter through the TPC field. It should be noted that in the NR communication system, the upstream 4 streams and below are all multiplexed on the same codeword. Therefore, for the scenario of 4 streams and below, only the same MCS can be selected for the data of all the scheduled streams.

The power calculated according to the above formula is the total transmission power of the PUSCH, and the power of each port is the average distribution of the total power in each port.

SRS and PUSCH use similar power control methods, and the terminal equipment will equally distribute the transmission power P _SRS,b,f,c (i,q _s ,l) to the antenna ports configured for the SRS.

If the terminal device transmits SRS in the SRS power control adjustment state 1 on the uplink part bandwidth (band width part, BWP) b of the carrier f of the serving cell c based on the configuration of the SRS-ResourceSet, the terminal device determines the SRS transmission by the following formula P _SRS,b,f,c (i,q _s ,l):

where:

P _CMAX,f,c (i) is the maximum output power of one SRS transmission i configured by the terminal equipment on the carrier f of the serving cell c;

P _{O_SRS,b,f,c} (q _s ) is the SRS power that the network device wants to obtain, which is configured by the parameter p0 in the SRS-ResourceSet;

q _s refers to the SRS resource set;

M _SRS,b,f,c (i) is the SRS bandwidth;

α _SRS,b,f,c (q _s ) is the path loss compensation factor, which is configured by the parameter alpha in SRS-ResourceSet;

PL _b,f,c (q _d ) is the downlink path loss estimation, which is measured by the path loss reference signal configured in the SRS-ResourceSet;

h _b,f,c (i,l) is the closed-loop power adjustment, which is indicated by downlink control information (DCI).

The SRS and PUSCH can be jointly controlled for power, that is, the power adjustment amount of the SRS and the power adjustment amount of the PUSCH are indicated by the TPC field of the same DCI; or,

The power control of the SRS can also be performed independently. At this time, the TPC command of the SRS is sent to the terminal device through the DCI format 2_3 carried on the physical downlink control channel (PDCCH).

In addition, the PUCCH and the PUSCH use a similar power control method to calculate the uplink power, and reference may be made to the introduction of the current related technology, which is not limited in this application.

3. Trigger of aperiodic SRS:

For an aperiodic sounding reference signal (aperiodic SRS, AP-SRS), when the terminal device receives a DCII for downlink scheduling, or a DCI for uplink scheduling, or a group common DCI, there is at least one SRS request filed in the DCI. A state is used to trigger 0, one or more SRS resource sets configured, as shown in Table 1:

Table 1 SRS request field (SRS request filed)

4. Port:

It can be understood as a virtual antenna recognized by the receiving device. In this embodiment of the present application, a port may refer to a transmit antenna port. For example, the reference signal of each port may be an unprecoded reference signal, or a precoding obtained by precoding the reference signal based on a delay vector. Coded reference signal; port can also refer to the reference signal port after beamforming, for example, the reference signal of each port can be a precoded reference signal obtained by precoding the reference signal based on an angle vector, or it can be based on A precoded reference signal obtained by precoding the reference signal with an angle vector and a delay vector. The signal of each port can be transmitted through one or more radio bearers (RBs).

The transmit antenna port may refer to an actual independent transmit unit (transceiver unit, TxRU). It can be understood that if spatial domain precoding is performed on the reference signal, the number of ports may refer to the number of reference signal ports, and the number of reference signal ports may be smaller than the number of transmit antenna ports.

Specifically, the channel transmitted through one antenna port on one symbol can be obtained by inference from the channel transmitted through the same antenna port on another symbol.

In the embodiments shown below, when referring to transmit antenna ports, it may refer to the number of ports that are not subjected to spatial precoding. That is, it is the actual number of independent transmission units. When referring to a port, in different embodiments, it may refer to a transmit antenna port or a reference signal port. The specific meaning expressed by the port can be determined according to the specific embodiment.

5. Uplink multi-antenna sending signals:

At a specific angle of the terminal device at a specific time, due to the limitations of the manufacturing process, production cost and other factors, as well as environmental factors such as occlusion (such as the internal circuit board of the terminal device), the large-scale parameters of the channels corresponding to different ports are different, that is, the two ports The corresponding channels can be denoted as h ₁ and αh ₂ (α<1), respectively. Taking two ports corresponding to two data streams as an example, it is assumed that the precoding matrix used by the uplink transmitter is:

Then the transmitted signal can be expressed as:

In this case, the received signal of the network device is:

y=Hx+n

Among them, H=[h ₁ αh ₂ ], then the SINRs of the two data streams are respectively

According to the current protocol, for an uplink transmission, the transmit power between different ports is evenly distributed. It can be seen from the above formula that due to the existence of α at a specific moment, the signals sent by different ports received by the network device side There is a large signal power difference between the two data streams, which leads to a large difference in the signal interference noise ratio (SINR) of the data streams corresponding to different ports. Scheme, MCS) are different.

It can be seen from the above that the PUSCH transmission network device involved in the current technology indicates the modulation mode of the PUSCH and the code rate of the channel coding to the terminal device through the MCS. For example, when the uplink channel quality is better (eg, when the SINR is high), the network device can increase the MCS to increase the uplink rate. In addition, the network device will also adjust the MCS according to the initial transmission block error rate (BLER) of the PUSCH. When the BLER exceeds a certain threshold, the MCS is reduced, and when the BLER is lower than a certain threshold, the MCS is increased, so that the BLER Maintain it at a certain level, say 10%, to maximize the upstream rate.

The uplink data or uplink signals involved in the embodiments of the present application include PUSCH, PUCCH, SRS, and the like.

Therefore, the uplink multi-antenna transmission signal involved in the current technology will bring the following problems:

1) When an uplink port with poor channel quality adopts an MCS with a higher code rate, the decoding error rate of the sub-signal sent by the network device to the uplink port is high;

2) When the uplink port with better channel quality cannot send the sub-signal of the uplink signal based on the MCS with higher code rate, the transmission capacity of the uplink port with better channel quality will be limited.

The above-mentioned manner of transmitting signals with multiple antennas in the uplink may not be conducive to improving the uplink throughput of the communication system on the one hand, and waste the transmit power corresponding to the port with high receiving power on the other hand.

In order to solve the above-mentioned possible defects in the current technology, a method for transmitting signals with multiple antennas is currently provided:

Single-port transmission is used, that is, only one antenna port transmits at the same time. When transmitting, select an antenna with a small path loss for uplink transmission. Due to internal circuit occlusion and other factors, the uplink transmit signal of some antennas will be strongly attenuated. Selecting an antenna with a small path loss for uplink transmission can avoid sending uplink signals on the blocked antenna.

However, NR communication systems support multi-input multi-output (MIMO) to improve spectral efficiency, throughput and system capacity. Adopting this single-port transmission mode limits the number of data streams of the uplink MIMO, thereby limiting the improvement of the uplink spectral efficiency and the uplink throughput.

At present, a method for transmitting signals with multiple antennas is also provided: the network device side, according to the measured signal power of each port of the terminal device, uses TPC commands to increase the transmit power of the port with low signal power received by the network device, or reduce the network device's receiving power. The transmit power of the port with high signal power received, so that the power of each port received by the network device is balanced.

However, the TPC command is 2 bits, corresponding to 4 power adjustment quantities, which are used to close-loop adjust the primary transmit power of the terminal device. As shown in Table 2, there are two types of TPC: cumulative type and absolute value type. For the cumulative type, the current power control adjustment amount is the sum of the power control adjustment amounts corresponding to the current and previous TPC commands; for the absolute value type, the current power control adjustment The control adjustment amount is the power control adjustment amount corresponding to the current TPC command. If the newly added field is used to indicate the power increase or decrease value of different ports, the DCI overhead will increase.

In order to solve the defects in the above-mentioned method for transmitting signals with multiple antennas, the present application provides a method for information indication. The power control value corresponding to each port of the terminal device is implicitly or explicitly indicated by the indication information, so that after the signals transmitted by different ports (or port sets) pass through channels with different channel states (such as corresponding channel large-scale parameter information), the network device The received signal power of different ports (or port sets) is balanced, thereby improving the uplink throughput, or reducing the power consumption of the terminal on the premise of ensuring a certain throughput.

It should be understood that the method for providing information indication in this embodiment of the present application may also be applied to other communication systems, and details are not described herein again.

Applied in a certain communication system, the steps performed by the receiver refer to the following terminal equipment, and the steps performed by the sender refer to the following network equipment. The transmission between the sender and the receiver can be performed by radio waves. Transmission can also be transmitted through transmission media such as visible light, laser, infrared, optical fiber, etc., which will not be described in detail below.

Hereinafter, without loss of generality, an interaction between a terminal device and a network device is used as an example to describe the information indication method provided in the embodiment of the present application in detail.

FIG. 2 is a schematic flowchart of a method for information indication provided by an embodiment of the present application. The method includes at least some of the following steps:

S210, the terminal device acquires DCI. Exemplarily, the network device sends DCI to the terminal device (or the terminal device receives DCI from the network device).

The DCI includes an RS request field and a first field, where the RS request field is used to indicate a triggered RS resource set, or in other words, the RS request field is used to determine the RS to be sent by the terminal device.

The RS request field may be, for example, an SRS request field. The RS request field can also be described as the RS request field. It should be noted that the name of the RS request field is used as an example and does not constitute a limitation to this application. With the evolution of the standard, other names may be used to describe the RS request field, and other names used to describe the essence of the RS request field should fall into the scope of protection of this application.

For ease of understanding, the following description takes the RS request field as the sounding reference signal SRS request field and the RS resource set as the SRS resource set as an example for description, but the name is not limited in this application.

It should be noted that this application does not limit how to carry the SRS request field and the first field in the DCI. For example, the SRS request field and the first field may be two different fields in the DCI; also for example, the SRS request field and the first field may be two parts of a certain field in the DCI.

Exemplarily, in the embodiment shown in FIG. 2, after receiving the DCI, the terminal device determines that the first field is used to determine the first information or the second information according to the state of the SRS request field carried in the DCI. The method shown in FIG. 2 The process also includes:

S220: The terminal device determines, according to the state of the SRS request field, that the first field is used to determine the first information or the second information.

It can be understood that the indication function of the first field in the DCI in this application varies according to the state of the SRS request field. For example, when the SRS request field indicates that an SRS resource set (eg, an aperiodic SRS resource set) is triggered, the first field is used to determine the first information, and when the SRS request field indicates that no SRS resource set is triggered, the first field is used for determining the second information.

Illustratively, the first information and the second information are different.

As a possible implementation manner, the first information is used to determine a time unit for sending an SRS (eg, a triggered aperiodic SRS).

Exemplarily, the first information may be an available time unit for sending the SRS resource set;

Exemplarily, the first information may also be a time offset between the time unit in which the SRS is sent and the time unit where the DCI used to trigger the SRS resource set is located.

Optionally, when the first information is used to determine the time unit for sending the SRS, it may be understood that the first field indicates the time unit for sending the SRS; or,

It can be understood that the first field indicates the information for determining the time unit for sending the SRS.

It should be understood that how the network device sends the DCI to the terminal device in this embodiment of the present application may refer to the description in the current related art, and may also refer to the description in the related art in the future communication technology, which is not limited in this application.

Exemplarily, the SRS request field in the embodiment shown in FIG. 2 can be understood as the SRS request filed shown in Table 1 above, and the SRS request field is not limited in this application, and the description in the current related art can be referred to. For example, the SRS request field includes 2 bits, and there are four states "00", "01", "10", and "11" in total. When the state of the SRS request field is "00", it indicates that no SRS resource set is triggered , when the status of the SRS request field is "01", "10" and "11" indicating that the SRS resource set is triggered. Wherein, no SRS resource set is triggered can also be understood as no SRS resource set needs to be sent, indicating that the SRS resource set is triggered can also be understood as sending an SRS resource set.

It should be noted that in the embodiments of this application, the indication information used to indicate the triggered SRS resource set is called the SRS request field, which is just an example, and does not constitute any limitation on the protection scope of this application. Others can be used to indicate the triggered SRS resource set. The indication information of the SRS resource set is also within the protection scope of this application.

When the SRS request field indicates that the SRS resource set is triggered:

As a possible implementation manner, the first field is a separate field in the DCI (for example, a newly added or defined field) used to indicate the information for determining the time unit for sending the SRS;

As another possible implementation manner, the first field is a separate bit (for example, a new or defined bit) in the DCI used to indicate the information for determining the time unit for sending the SRS;

As another possible implementation manner, the first field is a state newly added to an existing field in the DCI, and the newly added state indicates information used to indicate the time unit for determining the transmission of the SRS;

As another possible implementation manner, the first field is to re-interpret the existing field in the DCI, so that the existing field is used to indicate the information for determining the time unit for sending the SRS;

As another possible implementation manner, the first field is to re-interpret the existing bits in the DCI, so that the existing bits are used to indicate the information for determining the time unit for sending the SRS;

As another possible implementation manner, the first field is to re-interpret the state of an existing bit or field in the DCI, so that the state is used to indicate the information for determining the time unit for sending the SRS.

It should be understood that the possible forms of the above-mentioned first field are only examples, and do not constitute any limitation to the protection scope of this application. Other indication information or fields that can be used to indicate the information for determining the time unit for sending the SRS are all under the protection of this application. within the range.

In addition, the time unit involved in the embodiment of the present application may be a time unit such as a time slot, a mini-slot, a half-slot, a subframe, a half-frame, a frame, or a symbol. For ease of understanding, time units may be replaced by time slots.

As a possible implementation manner, the second information includes at least one piece of power information corresponding to at least one port respectively, and the at least one piece of power information is respectively used to determine the first transmit power of the at least one port. The above-mentioned first field indicating the second information may be understood as the first field indicating at least one power information corresponding to at least one port respectively.

In this embodiment of the present application, the first transmission power may be referred to as uplink transmission power. The first transmission power and the uplink transmission power appearing hereinafter may be replaced with each other.

As another possible implementation manner, the second information may also be used to determine power control parameters of different TRPs in multiple TRP scenarios.

As another possible implementation manner, the second information may also be used to determine the frequency resource allocation of the UE (for example, a RedCap UE);

For example, the second information is used to determine a bandwidth part (BWP) in which the UE is activated.

As another possible implementation manner, the second information may also be used to indicate a slot format indication (slot format indication, SFI) index;

For example, the second information is used to indicate that the time slot F with insufficient uplink (UL) symbols is changed to the time slot F with more UL symbols, or the time slot U;

As another possible implementation manner, the second information may also be used to indicate carrier switching.

When the SRS request field indicates that the SRS resource set is triggered, how the first field indicates the time unit for determining the transmission of the SRS is not described in detail in this application. This application mainly relates to how the first field is used to determine at least one power information corresponding to at least one port when the SRS request field indicates that no SRS resource set is triggered.

When the SRS request field indicates that no SRS resource set is triggered, how the first field is used to determine other information (such as the power control parameters of different TRPs in the above multiple TRP scenarios, the partial bandwidth of the UE being activated, the slot format indication information, etc. ) may refer to the manner in which the first field indicates the power information, or may also refer to the manner of indicating other information capable of realizing this function, which will not be repeated in this application.

The at least one power information corresponds to at least one port.

For example, if the first field is used to determine the power information of the three ports, the first field is used to determine the three power information respectively, and the three power information corresponds to the three ports. The three pieces of power information are respectively used to determine the first transmit power of the three ports.

Exemplarily, the ports involved in the embodiments of the present application are used to send uplink information (or uplink signals), including antenna ports or SRS ports. For example, port a is port i, or port a is a port group consisting of multiple different port i. where i is an integer. For example, i=0, or i=1.

Exemplarily, the value of the first transmit power may be a decibel value or an absolute power value.

Exemplarily, the uplink information is uplink data information PUSCH, or uplink control information physical uplink control channel (physical uplink control channel, PUCCH), or uplink signal SRS.

Exemplarily, the power information is used to determine the uplink transmission power (the power information is any one of the above-mentioned at least one power information, and the uplink transmission power is the uplink transmission power corresponding to the power information in the above-mentioned at least one uplink transmission power) including: There are several possibilities as follows: Possibility 1. The power information is the uplink transmission power.

For example, the first field is used to determine first power information corresponding to the first port, where the first power information is the first uplink transmission power corresponding to the first port.

Specifically, in the embodiment of the present application, there is an association relationship between the uplink transmission power of a certain port and the indication state of the first field. The association relationship is pre-defined by a protocol or pre-configured by a network device, and may be referred to as a preset association relationship. The terminal device knows the correlation between the uplink transmission power of a certain port and the indication state of the first field, and can determine the uplink transmission power of the port when it knows the indication state of the first field.

As a possible implementation manner, the above-mentioned association relationship is predefined. For example, the protocol predefines the association relationship between the uplink transmission power value of the port that sends the uplink information and the identifier of the port.

As another possible implementation manner, the above-mentioned association relationship is indicated by the network device. For example, the network device indicates the association relationship between the uplink transmission power value of the port sending the uplink information and the identifier of the port. For different ports, the association relationship indicated by the network device may be the same or different. For example, for ports identified by different groups, the association relationship indicated by the network device is different; for example, for ports identified by different groups, the association relationship indicated by the network device is different.

For example, the terminal device determines the uplink transmission power value of port i=first power information according to a predefined association relationship. Wherein, the predefined association relationship is used to determine the following corresponding relationship:

A certain state in the first field corresponds to the first power information, the first power information corresponds to port i, and the state in the first field corresponds to port i.

Then the terminal device can determine that the state of the first field indicates that the uplink transmission power value of port i is the first power information according to the predefined association relationship and after learning the state of the first field.

port i is the i-th port of the terminal device, or the i+1-th port. Wherein, i is predefined, or i is configured by the network device through signaling (eg, RRC), or i is indicated by the network device through downlink information (eg, DCI).

The first power information is predefined, or the first power information is configured by the network device through signaling (eg, RRC). For example, if the first power information is equal to 0, it indicates that the uplink transmission power on the port is 0. For another example, the first power information is one of the sets {0, X1, . . . , Xn}, and the first field indicates that a certain value in the set is the first power information.

Possibly 2. The power information is an offset, and the offset and the basic uplink transmission power (also referred to as the second transmission power) are used to determine the uplink transmission power. Signaling configuration and/or the value indicated by the second field, and the number of antenna ports used for one transmission, the second field includes the transmission power control field TPC command contained in the DCI, or the second field may be DCI and other fields used to determine the second transmit power.

In a possible implementation manner, the basic uplink transmission power is determined based on the total transmission power of the physical uplink shared channel PUSCH and at least one port.

At present, the related art provides a method for calculating the basic uplink transmission power, which is not limited in this embodiment of the present application. Exemplarily, the network device indicates to the terminal device the open-loop power control parameters for uplink information transmission (eg, the above-mentioned _{PO_PUSCH,b,f,c} ₍ j), PLb,f, _c (qd) , α _{b, f, c} (j) and Δ _{TF, b, f, c} (i)); the network equipment indicates the closed-loop power control parameters for the terminal equipment through the DCI carried on the PDCCH (for example, the above f _{b ,f,c} (i,l)). Wherein, the DCI includes: DCI format 0_0, DCI format 0_1, or information in DCI format 2_3 (eg, the above-mentioned TPC command).

It should be noted that, in the current protocol, the indications of the open-loop power control parameters and the closed-loop power control parameters are in units of one PUSCH transmission, and the transmission power of one PUSCH is evenly distributed on each port. Therefore, in a PUSCH transmission, the transmit power on each port is the same.

That is, the basic uplink transmission power involved in the embodiments of the present application satisfies the following formula:

Basic uplink transmission power=total transmit power of one PUSCH transmission/total number of ports with non-zero power used for this PUSCH transmission.

In the embodiment of the present application, the uplink transmission power corresponding to a certain port is determined according to the basic uplink transmission power and the offset corresponding to the port. Exemplarily, the uplink transmission power corresponding to the port, the basic uplink transmission power and the offset corresponding to the port are determined. The amount satisfies the following formula:

Uplink transmission power = basic uplink transmission power + offset.

It should be understood that the above basic uplink transmission power calculation method is only an example, and does not constitute any limitation to the protection scope of the present application. The embodiments of the present application mainly relate to how to adjust the uplink transmission power when the current scheme for calculating the uplink transmission power cannot meet the receiving power requirement of the network device.

Specifically, in the embodiment of the present application, there is an association relationship between a certain port and the uplink transmission power corresponding to the port. The terminal device can determine the uplink transmission power of the port according to the port identifier and the association relationship.

The association relationship is pre-defined by a protocol or pre-configured by a network device, and may be referred to as a preset association relationship.

As another possible implementation manner, the above-mentioned association relationship is indicated by the network device. For different ports, the association relationship indicated by the network device may be the same or different. For example, for ports identified by different groups, the association relationship indicated by the network device is different; for example, for ports identified by different groups, the association relationship indicated by the network device is different.

For example, the terminal device determines the uplink transmission power value of port i = the power value of one PUSCH transmission/the total number of antenna ports with non-zero power used for this PUSCH transmission + the first offset according to the predefined association relationship.

Wherein, the predefined association relationship is used to determine the following corresponding relationship:

A certain state in the first field corresponds to the first offset, the first offset corresponds to port i, and the state in the first field corresponds to port i.

The possible values of the first offset are predefined, or the possible values of the first offset are configured by the network device through signaling (eg, RRC). For example, the first offset is equal to 0, indicating that the port does not need to perform power offset. For another example, the first offset may be a positive value X, indicating that the port needs to perform power boost compensation. For another example, the first offset may be a negative value -X, indicating that the port needs to perform power reduction. Among them, X can be a decibel value or an absolute power value. For another example, the first offset may be one of a set {0, X1, . . . , Xn}, and the first field may indicate that a certain value in the set is the first offset. For example, the possible value of the first offset includes 3dB, which means that the power of the port needs to be doubled. For another example, the possible value of the first offset includes -3dB, which means that the power of the port needs to be reduced by half.

Possibly three, the power information is the differential power offset, and the differential power offset and the transmit power of the preset port are used to determine the uplink transmission power.

For example, the first field is used to determine first power information corresponding to the first port, where the first power information is the first differential power offset, and the first uplink transmission power corresponding to the first port is based on the first differential power offset and The transmit power of a preset port is determined. The preset port is predefined or indicated by the network device, and the transmission power of the preset port can be calculated according to the current transmission power calculation method, or can also be calculated in other ways. In the embodiment of the present application, the game preset The manner of determining the transmit power of the port is not limited.

Exemplarily, the uplink transmission power corresponding to the port, the transmit power of the preset port, and the differential power offset corresponding to the port satisfy the following formula:

Uplink transmission power = transmit power of the preset port + differential power offset.

The possible values of the differential power offset are predefined, or the possible values of the differential power offset are configured by the network device through signaling (eg, RRC).

For example, if the differential power offset is equal to 0, it means that the port has the same transmit power value as the preset port.

For another example, the differential power offset may be a positive value X, indicating that the port needs to perform power boosting based on the transmit power of the preset port.

For another example, the differential power offset may be a negative value -X, indicating that the port needs to be reduced based on the transmit power of the preset port. Among them, X can be a decibel value or an absolute power value.

For another example, the differential power offset may be one of the sets {0, X1, . . . , Xn}, and the first field may indicate that a certain value in the set is the differential power offset. For example, if the possible value of the differential power offset includes 3dB, it means that the power of the port needs to be doubled based on the transmit power of the preset port; for another example, if the possible value of the differential power offset includes -3dB, it means that the The power of the port needs to be reduced by half based on the transmit power of the preset port.

Possibility 4. The power information is an independent variable, and the independent variable and a preset power calculation formula are used to determine the uplink transmission power. Wherein, the uplink transmission power of each port is obtained according to the preset power calculation formula and the value of the independent variable.

For example, the preset power calculation formula includes the sum of the power values on all ports used for this PUSCH transmission and whose power is not 0, and/or the power difference between all the ports used for this PUSCH transmission and whose power is not 0 difference value. Alternatively, the preset power calculation formula includes the sum of the power values on all ports that are used for this PUSCH transmission and whose power is not 0, and also includes the power difference between all the ports that are used for this PUSCH transmission and whose power is not 0. satisfied relationship. For example, the association relationship is that the power on the port used for the current PUSCH transmission and whose power is not 0 is equal to the value obtained by subtracting the power information (the value indicated in the first field).

The first field is used to determine at least one piece of power information in the following ways:

Mode 1, the first field includes at least one bit, the power information of each port is indicated by its corresponding bit, and the power information corresponding to a certain port is the power information corresponding to the bit state in the power information set corresponding to the port. The terminal device may determine the power information of the port corresponding to the bit according to the state of the bit in the first field.

For ease of understanding, the bit included in the first field indicates two pieces of power information corresponding to two ports as an example for description.

Exemplarily, the first field used to determine at least one uplink transmission power corresponding to at least one port respectively includes:

The first field is used to determine the first power information corresponding to the first port, and the first field is used to determine the second power information corresponding to the second port;

The first field is used to determine the first power information corresponding to the first port and includes:

The first field includes a first bit, the first bit is used to determine the first power information, the first power information is the power information corresponding to the state of the first bit in the preset first power information set, and the first bit includes at least one bit;

The first field is used to determine the second power information corresponding to the second port and includes:

The first field includes a second bit, the second bit is used to determine the second power information, the second power information is the power information corresponding to the state of the second bit in the preset second power information set, and the second bit includes at least one bit.

The preset first power information set and the preset second power information set are predefined by the protocol or preconfigured by the network device, the state of the first bit refers to the bit state of the first bit, and the state of the second bit The state refers to the bit state of the second bit.

Exemplarily, the network device pre-configuration involved in this application may be pre-configured by the network device through a high-layer signaling RRC message, or pre-configured through a high-layer signaling MAC control element (MAC control element, MAC CE).

Exemplarily, the preset first power information set and the preset second power information set are included in the same preset power information set, or the preset first power information set and the preset second power information set The sets are two different sets of power information configured respectively.

Further, before determining the above-mentioned power information, the terminal device learns the preset association relationship (such as the association relationship predefined by the protocol, or receives the association relationship from the network device), and specifically, the association relationship indicates the following corresponding relationship :

The preset first set of power information corresponds to the first port, the preset second set of power information corresponds to the second port, and the first bit corresponds to the first set of power information (or the first bit corresponds to the first set of power information). port), the second bit corresponds to the second power information set (or the second bit corresponds to the second port), the state of the first bit corresponds to the power information in the first power information set, the second The state of the bit corresponds to the power information in the second set of power information.

For ease of understanding, the power information is used as an example for the offset:

For example, port #1 corresponds to offset set #1, and port #2 corresponds to offset set #2, wherein offset set #1 includes {offset #1, offset #2}, offset Quantity set #2 includes {offset #3, offset #4}. The first field includes two bits (bit #1 and bit #2), bit #1 corresponds to port #1 and bit #2 corresponds to port #2.

When the status of bit #1 is "0", the offset of port #1 is offset #1; when the status of bit #1 is "1", the offset of port #1 is offset #2; When the status of bit #2 is "0", the offset of port #2 is offset #3; when the status of bit #2 is "1", the offset of port #2 is offset #4.

Exemplarily, the offset set corresponding to each port may be predefined or may also be preconfigured by the network device. For example, the protocol pre-defined offset set #1 and offset set #2; also for example, the network device pre-configures the offset set #1 and offset set #2; also for example, the protocol pre-defined offset set #1, network device pre-configured offset set #2.

Exemplarily, the association relationship between each port and the offset set may be predefined or may also be preconfigured by the network device. For example, the protocol predefined port #1 corresponds to the offset set #1, and port #2 corresponds to the offset set #2; for example, the network device pre-configured port #1 corresponds to the offset set #1, and port #2 corresponds to the offset set #1. Shift Set #2.

Exemplarily, the association relationship between the bits included in the first field and the ports may be predefined or may also be preconfigured by the network device. For example, the protocol pre-defines that bit #1 included in the first field corresponds to port #1, and bit #2 included in the first field corresponds to port #2; for example, the network device preconfigures that bit #1 included in the first field corresponds to Port #1, bit #2 included in the first field corresponds to port #2.

Exemplarily, the first field used to determine the first power information corresponding to the first port includes:

The first bit state of the first field is used to determine first power information, where the first power information is power information corresponding to the first bit state in a preset first power information set;

The preset first power information set corresponds to the first port, the preset second power information set corresponds to the second port, the first bit state corresponds to the power information in the first power information set, and the second bit The state corresponds to power information in the second set of power information.

For example, port #1 corresponds to offset set #1, and port #2 corresponds to offset set #2, wherein offset set #1 includes {offset #1, offset #2}, offset Quantity set #2 includes {offset #3, offset #4}. The first field includes four bit states ("00", "01", "10", "11"), the bit states "00", "01" correspond to port #1, and the bit states "10", "11" correspond to Port #2.

The bit status of the first field is "00", and the offset of port #1 is offset #1; the bit status of the first field is "01", and the offset of port #1 is offset #2; The bit status of the first field is "10", and the offset of port #2 is offset #3; the bit status of the first field is "11", and the offset of port #2 is offset #4.

Exemplarily, the offset set corresponding to each port may be predefined or may also be preconfigured by the network device.

Exemplarily, the association relationship between each port and the offset set may be predefined or may also be preconfigured by the network device.

Exemplarily, the association relationship between the bit state of the first field and the port may be predefined or may also be pre-configured by the network device. For example, the bit states of the first field predefined by the protocol are "00" and "01" corresponding to port #1, and the bit states of the first field are "10" and "11" corresponding to port #2; for example, the network device is preconfigured The bit states of the first field are "00" and "01" corresponding to port #1, and the bit states of the first field are "10" and "11" corresponding to port #2.

Exemplarily, the association relationship between the bit state of the first field and the offset in the offset set corresponding to the port may be predefined or may also be pre-configured by the network device.

Mode 3, the first field includes at least one bit state, the at least one bit state corresponds to at least one piece of power information, the power information of each port is indicated by the bit state of the corresponding first field, and the power information of a certain port is: Power information corresponding to the bit state of the first field.

Exemplarily, the first field used to determine the first power information includes:

The first bit state of the first field indicates first power information, and the first power information is power information corresponding to the first bit state in a preset power information set;

The first field is used to determine the second power information including:

The second bit state of the first field indicates the second power information, and the second power information is power information corresponding to the second bit state in the preset power information set.

The preset power information set is predefined by a protocol or preconfigured by a network device.

The power information corresponding to the first port in the preset power information set, the power information corresponding to the second port in the preset power information set, the first bit state corresponding to the power information of the first port, the second bit The state corresponds to the power information of the second port.

For example, the protocol predefined or network device preconfigured offset set {offset #1, offset #2, offset #3}, and the protocol predefined or network device preconfigured offset #1 and offset Shift #2 corresponds to port #1, and offset #3 corresponds to port #2. The first field includes four bit states ("00", "01", "10", "11"), and the offset of the bit state "00" corresponding to port #1 and port #2 is a value predefined by the protocol, Or a value preconfigured by a network device. For example, the bit state "00" corresponds to the offset of port #1 and port #2 being 0. In this case, the effect of using the same bit state to indicate two port offsets can be achieved. Bit state "01" corresponds to offset #1, bit state "10" corresponds to offset #2, and bit state "11" corresponds to offset #3.

Exemplarily, the above-mentioned port #1 is a port in a certain port set, and the offset of the port in the port set is the same as the offset of port #1, by indicating the offset of port #1 together. Indicates the offsets of multiple ports in the port set; for the same reason, the above-mentioned port #2 is a port in a certain port set, and the offset of the port in the port set is the offset of port #2 Similarly, the offsets of multiple ports in the port set are indicated together by indicating the offsets of port #2. That is, the above-mentioned first field may indicate the offsets of all ports in the entire port set.

It should be understood that the above-mentioned ways 1 to 3 only illustrate how the first field directly indicates the power information of at least one port, and does not constitute any limitation on the protection scope of the present application. The manner is also within the protection scope of the present application, and will not be repeated here.

In addition, the above description only takes the power information as the offset as an example for description. When the power information is other cases, it is similar to the above, and will not be repeated here.

For example, when the power information is the uplink transmission power, the above offset can be replaced with the uplink transmission power, and there is no need to further calculate the uplink transmission power based on the basic uplink transmission power;

Also for example, when the power information is a differential power offset, the above offset can be replaced with a differential power offset, and the uplink transmission power is further calculated based on the differential power offset;

For another example, when the power information is an independent variable, the above-mentioned offset can be replaced with an independent variable, and the power calculation formula corresponding to each port is determined based on the independent variable and the preset power calculation formula, and is further calculated based on the power calculation formula. Uplink transmission power.

It should be noted that when the power information is an offset, the offset #1 of a certain (or some) port can also be indicated, and the offset #2 of other ports can be determined according to the offset. (For example, offset #2 and offset #1 have opposite values).

Exemplarily, the first field used to determine at least one piece of power information corresponding to at least one port respectively includes:

The first field is used to determine the first power information corresponding to the first port, and the first power information is used to determine the first transmit power corresponding to the first port,

The second power information corresponding to the second port is related to the first power information; or,

The first transmit power corresponding to the second port is related to the first transmit power corresponding to the first port; or,

The second power information corresponding to the second port is related to the first transmit power corresponding to the first port; or,

The first transmit power corresponding to the second port is related to the first power information corresponding to the first port.

For example, if the first power information is the first offset, the correlation between the second power information corresponding to the second port and the first power information can be understood as the second offset corresponding to the second port and the first offset Correlation (for example, the second offset is the opposite number of the first offset, but the second power information is not limited to be the opposite of the first offset in this application, it can be determined according to the first offset ).

Also for example, if the first power information is the first transmit power corresponding to the first port, the first transmit power corresponding to the second port is related to the first power information corresponding to the first port (for example, the first transmit power corresponding to the second port The transmit power is the inverse of the first power information corresponding to the first port).

For another example, the first power information is the first argument, and the first argument and the predefined rule determine the first transmit power corresponding to the first port, then the first transmit power corresponding to the second port is the same as the first transmit power corresponding to the first port. A transmit power correlation (eg, the first transmit power corresponding to the second port is the inverse of the first transmit power corresponding to the first port).

Exemplarily, the first field indicating the first offset may refer to the indication manners in the foregoing manners 1 to 3. For example, similar to the above-mentioned mode 1, the first bit (at least one bit) in the first field is used to determine the first offset, and the first offset is the same as the first offset in the preset first offset set. The offset corresponding to the state of one bit is different from Mode 1 in that the second offset can be determined according to the first offset without additional indication;

For another example, similar to the above-mentioned mode 2, the first bit state in the first field is used to determine the first offset, and the first offset is the same as the first bit state in the preset first offset set. The corresponding offset is different from the method 2 in that the second offset may be determined according to the first offset without additional indication.

For example, port #1 corresponds to offset set #1, wherein offset set #1 includes {offset #1, offset #2}. The first field includes 1 bit (bit #11), bit #1 corresponds to port #11.

When the bit status of bit #1 is "0", the offset of port #1 is offset #1, and the offset of port #2 is the opposite value of offset #1 (-offset #1 ); when the bit state of bit #1 is "1", the offset of port #1 is offset #2, and the offset of port #2 is the opposite value of offset #2 (-offset #2).

Jointly indicating the power of multiple ports can further save DCI overhead. Among multiple ports, while one port performs power boost compensation, the other port performs power reduction, which can ensure that the total power of the ports in a PUSCH transmission is the same, thereby ensuring that the interference of the PUSCH transmission to other information can be avoided. control.

Further, the above-mentioned first port is a port in a certain port set, and the uplink transmission power corresponding to the port in the port set is the first uplink transmission power; and/or, the above-mentioned second port is a certain port set. A port in the port set, and the uplink transmission power corresponding to the port in the port set is the second uplink transmission power.

Exemplarily, the first port is any port in the first port set, and the uplink transmission power corresponding to each port in the first port set is the first uplink transmission power; and/or,

The second port is any port in the second port set, and the uplink transmission power corresponding to each port in the second port set is the second uplink transmission power.

Under the premise of not increasing the DCI overhead, it is guaranteed that after the signals transmitted by different ports (or port sets) pass through channels with different channel states (such as corresponding channel large-scale parameter information), different ports (or port sets) received by the network device signal power balance, thereby improving the uplink throughput, or reducing the power consumption of the terminal equipment on the premise of ensuring a certain throughput.
