detailed description

In order to make the purpose, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

When the PUSCH repeatedly transmits uplink service data and the N _{REs of} at least 2 PUSCHs are not equal, the solution of the present invention is adopted. The terminal device obtains control information, determines the uplink service transmission blocks repeatedly sent in the N PUSCHs according to the control information, and then according to The resource quantity value and the size of the uplink service transmission block determine the respective "information transmission rate" of the N PUSCHs, and further adjust the respective transmission powers of the N PUSCHs according to the information transmission rate, which can satisfy the transmission of PUSCH repeated transmission Power requirements and efficiency.

The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Fig. 1 is a flowchart of an embodiment of a method for determining the power adjustment value of each PUSCH according to the value of the amount of resources actually occupied by the PUSCH.

The embodiment of the application proposes a method for uplink channel transmit power control, which includes the following steps:

Step 101: Receive control information, where the control information is used to determine N PUSCHs that repeatedly send uplink service transport blocks.

PUSCH is divided into two types: Type 1, where the network device sends downlink control information (DCI) to schedule the PUSCH sent by the terminal device, which is a dynamic authorized scheduling. Type 2: The network device semi-statically configures the PUSCH sent by the terminal device, that is, the network device instructs the terminal device to send the PUSCH through an authorization-free scheduling method. According to section 6.3.2 of 3GPP TS38.331.V20, in type 1, the terminal equipment can transmit uplink data on these resources according to the configured RRC signaling. In type 2, after receiving the configured RRC signaling, the terminal device can transmit uplink data on these resources if it receives the PDCCH with the CS-RNTI scrambled CRC check bit to activate these resources.

In this embodiment, the terminal device obtains control information, and according to the control information, determines to repeatedly send uplink service transmission blocks in N PUSCHs. The control information may be, for example, physical downlink control information for realizing dynamic authorization scheduling. The physical downlink control information is used to schedule the terminal device to repeatedly send uplink service transmission blocks in N PUSCHs, or to activate pre-configured type 2 PUSCH configuration resources. The control information may also be high-level signaling, for example, to configure type 1 PUSCH configuration resources.

According to the control information, the terminal device determines to repeatedly send the uplink service transmission block in N PUSCHs, and the size of the uplink service transmission block is, for example, S ₁ bit. The amount of resources actually used for the uplink service transmission block in each of the N PUSCHs may be different. For example, at least two of the N PUSCHs actually occupy different amounts of resources, and the N PUSCHs include the first PUSCH. Unlike the second PUSCH, the number of symbols included in each of the first PUSCH and the second PUSCH is different. Further, it may be that at least 2 of the N PUSCHs are located in the same time slot, for example, the first PUSCH and the second PUSCH are located in the same time slot; it may also be that at least 2 of the N PUSCHs are located in different time slots. For example, the first PUSCH and the second PUSCH are located in different time slots, and the last symbol of the first PUSCH and the first symbol of the second PUSCH are adjacent in time.

Step 102: Determine the information transfer rate of the i-th PUSCH by using the resource quantity value of at least one PUSCH as a reference value, where the information transfer rate is inversely proportional to the reference value and proportional to the number of bits of the transport block, Among them, N≥2 and 1≤i≤N.

Assuming that the number of resource units for the i-th PUSCH in N PUSCHs to transmit uplink traffic transport blocks is N _RE (i), 1≤i≤N, to determine the respective transmission power of the N PUSCHs, first determine the information Transmission rate.

As an optional embodiment, the reference value is the value of the number of resources actually occupied by the j-th PUSCH. Among them, the actual number of resources occupied by the jth PUSCH is:

Where M _RB (j) is the number of frequency domain resource blocks occupied by the jth PUSCH; N _SYMB (j) is the number of time domain symbols occupied by the jth PUSCH;

Is the number of subcarriers except DMRS and or PTRS in a resource block of symbol 1; or,

Is the number of subcarriers in a resource block of symbol l; 1≤j≤N. It should be noted that the value range of j includes j=i.

When j=i, determine the information transmission rate of the jth PUSCH according to the resource quantity value of the jth PUSCH in the N PUSCHs, and then determine the power adjustment amount of the jth PUSCH according to step 103. In this way, the power adjustment amount of the jth PUSCH is adapted to the modulation and coding rate actually used by the jth PUSCH, which is the most suitable in terms of the receiving performance and power efficiency of the jth PUSCH.

Optionally, the value of j is preset, for example, j=1.

Further preferably, the reference value satisfies: N _RE (j)=min[N _RE (i)] or N _RE (j)=max[N _RE (i)], where i=1,...,N; That is to say, j corresponds to the one that occupies the largest time and frequency resources among the N PUSCHs; or, j corresponds to the one that occupies the smallest time and frequency resources among the N PUSCHs.

When the number of subcarriers does not consider DMRS and or PTRS, the reference value subtracts the influence of the DMRS and or PTRS on the number of occupied resources in the N PUSCHs.

The resource quantity value N _RE is determined according to the total number of resource units included in the N PUSCHs, and then the information transmission rate of each PUSCH in the N PUSCHs in the PUSCH is determined according to the resource quantity value. Assuming that the N PUSCHs include a total of

RBs, the total number of resource units included in N PUSCHs can also be calculated with reference to formula (1). The information transmission rate of each PUSCH in the N PUSCHs is determined according to the N _RE value, and then the power adjustment amount of each PUSCH is determined according to step 103. The resource quantity value determined by the time and frequency resources occupied by the N PUSCHs is constant, and it is determined according to the N _RE value that the information transmission rate of each PUSCH in the N PUSCHs is the same, and thus the power adjustment amount is the same. In this way, it is beneficial to share the DMRS among N PUSCHs, and it is beneficial to the smooth transmission power of the terminal equipment.

As another optional embodiment, the reference value may also be an average value of the number of resources actually occupied by the N PUSCHs.

Step 103: Adjust the transmission power of the i-th PUSCH according to the information transmission rate. For example, when the information transmission rate increases, the transmission power is increased; when the information transmission rate decreases, the transmission power is decreased.

It should be noted that the transmission power P of the terminal device is determined by multiple factors, and the information transmission rate is one of them. The information transmission rate is determined according to the uplink service transmission block size transmitted in the PUSCH and the resource quantity value N _{RE of the} PUSCH. In addition, the power P of the PUSCH sent by the terminal device is also related to factors such as path loss, path compensation factor, power adjustment control command word sent in the downlink control information, and operating point of open-loop transmission power control. According to the above steps 101 to 102, the terminal device can determine the respective information transmission rates of the N PUSCHs. According to the respective information transfer rates of the N PUSCHs and other respective transmission power determining factors, the terminal device can determine the respective transmission powers of the N PUSCHs.

For example, Chapter 7 of 3GPP TS 38213 Vf40 involves NR giving a way to determine the transmission power of the uplink channel of the system, and calculate the power change by the information transfer rate. On the serving cell c of the carrier f, the transmission power P _{PUSCH of the} i-th transmission time on the uplink BWPb corresponding to the power configuration set parameter index j is P _{PUSCH, b, f, c} (i, j, q _d , l) contains Δ _{TF, b, f, c} terms, we call it power adjustment. E.g,

The information transfer rate is defined as:

In formula 2, C represents the number of code blocks (CB, code block) transmitted on the PUSCH, and K _r is the size of the code block r. In the present invention, the number of bits of the uplink service transmission block can be used. Take the number of resource units N _RE as the value of the number of resources. The information transmission rate is determined according to the uplink service transmission block size transmitted in the PUSCH and the resource quantity value N _{RE of the} PUSCH.

This application does not limit the ratio between the power adjustment value and the information transmission rate. As an example, for example, a relationship included in the 3GPP TS 38213 Vf40 standard is:

among them,

The value of and K _S is configured by the network device to the terminal device.

Finally, the terminal device transmits the N PUSCHs according to the respective transmission powers of the N PUSCHs.

2 is a flowchart of an embodiment of a method for determining the power adjustment value of each PUSCH according to the resource quantity indicated by the PUSCH.

Step 201: Receive control information, and according to the control information, determine N PUSCHs that repeatedly send uplink service transport blocks.

The control information is used to determine N PUSCHs that repeatedly send uplink service transport blocks.

Step 202: Determine scheduling resource allocation values of N PUSCHs according to the control information.

As a preferred embodiment of the method of the present invention, the control information is also used to determine N PUSCH scheduling resource allocation values;

The resource quantity value is determined according to the resource allocation field of the PUSCH in the control information, and then the information transmission rate of each PUSCH in the N PUSCHs in the PUSCH is determined according to the resource quantity value. Assume that the PUSCH resource allocation field of the control information indicates that the PUSCH includes in the frequency domain

RB, including in the time domain

Symbols. According to

with

Determine the value of the resource quantity.

At this time, the value of the number of resources is the value of the number of allocated resources rather than the value of the number of resources actually occupied.

The PUSCH resource allocation field in the control information may directly indicate the starting symbol and overall length of the N PUSCHs; the PUSCH resource allocation field in the control information may also indicate the starting symbol and overall length of the first PUSCH, and The value of N; or, the resource allocation field of the PUSCH in the control information may also indicate the respective start symbol lengths of the N PUSCHs. The resource allocation field of the PUSCH in the control information determines the resource quantity value, which may be determined according to part or all of the resource allocation field of the PUSCH. For example, if the PUSCH resource allocation field in the control information indicates the start symbol and overall length of the first PUSCH, and the value of N, the number of resources may be determined based on the start symbol and overall length of the first PUSCH. It may be determined based on the start symbol and overall length of the first PUSCH, and the value of N. Part or all of the resource allocation field of the PUSCH is specifically used to determine whether the resource quantity value is preset.

Step 203: Use the resource quantity value of at least one PUSCH as a reference value to determine the information transmission rate of the i-th PUSCH, where the information transmission rate is inversely proportional to the reference value and directly proportional to the number of bits of the transport block, Among them, N≥2 and 1≤i≤N.

Assuming that the number of resource units used to transmit the uplink traffic transport block of the i-th PUSCH in the N PUSCHs is N _RE (i), the power adjustment amount Δ _{TF, b, f, c} in the transmission power of the N PUSCHs must be determined, The resource quantity value can be determined first according to the scheduling resource allocation value.

It should be noted that the uplink/downlink configuration of symbols during the transmission of the N PUSCHs by the network equipment will affect the resources occupied by the actual transmission of the i-th PUSCH among the N PUSCHs. For example, the control information indicates that the first transmission block of PUSCH is sent on the 5th to 14th symbols of time slot n, but at this time, the network equipment indicates the 12th to the 12th to 14th symbols of time slot n through SFI (Slot format indication) information. The 14 symbols are downlink, and the first PUSCH actually only occupies the 5th to 11th symbols of the time slot n. If the resource quantity value is determined by the actual resource quantity of the first PUSCH, in the case that the SFI sent by the network equipment is not correctly received on the terminal equipment side, the network equipment expects the information transmission rate determined by the terminal equipment and the terminal equipment actually determines The difference in information transmission rate causes inappropriate adjustment of the transmission power of the terminal equipment by the network equipment, which causes the system efficiency to deteriorate. On the contrary, if the resource allocation field of the PUSCH in the control information is used to determine the resource quantity value, it can be avoided that the network device's expectation of the information transmission rate determined by the terminal device is different from the information transmission rate actually determined by the terminal device.

At this time, preferably, the reference value is: the value of the number of resources allocated by the jth PUSCH, or the average value of the number of resources allocated by the N PUSCHs, or the sum of the number of resources allocated by the N PUSCHs.

When the reference value is the value of the number of resources allocated by the jth PUSCH, it is further preferred that the reference value is subtracted from the value of the number of resources allocated by DMRS and or PTRS in the jth PUSCH.

When the reference value is the sum of the resource quantity values allocated by N PUSCHs, it is further preferred that the reference value does not include the resource quantity values allocated by DMRS and or PTRS in the N PUSCHs.

For example, resource quantity value

The information transmission rate of each PUSCH in the N PUSCHs is determined according to the N _RE value. For another example, the resource quantity value

among them

They are the DMRS and PTRS loads indicated by the control information. The DMRS load includes the DMRS used by the terminal device to demodulate the PUSCH and the DMRS load of other terminal devices that reuse resources with the terminal device. The information transmission rate of each PUSCH in the N PUSCHs is determined according to the N _RE value.

Since the N PUSCHs are indicated by the same control information, it is determined according to the N _RE value that the information transmission rate of each PUSCH in the N PUSCHs is the same. In this way, it is conducive to sharing DMRS among N PUSCHs, and it is conducive to smooth transmission power of terminal equipment.

Step 204: Adjust the transmission power of the i-th PUSCH according to the information transmission rate, for example, when the information transmission rate increases, increase the transmission power; when the information transmission rate decreases, decrease the transmission power.

In step 204, according to the information transfer rate, for example, the BPRE shown in formula (2), the power adjustment amount, for example, ΔTF _{,b,f,c in} formula (3), is further calculated.

Figure 3 is a PUSCH application scenario 1 for retransmitting service data in the method of this application. One uplink scheduling grant indicates multiple PUSCH repetitions. There can be 2 or more PUSCH repetitions in a slot, or multiple PUSCH repetitions can cross the slot boundary between adjacent slots, but Each PUSCH transmission in multiple PUSCH repeated transmissions cannot cross the slot boundary, which is also called mini-slot level repetition.

If the starting symbol of the uplink scheduling authorization to schedule the PUSCH is located at the S symbol of the time slot n, and the time length of the scheduled PUSCH is L symbols, the uplink scheduling authorization to schedule the terminal device to repeatedly transmit the PUSCH N times. If S+(X-1)×L, 1≤X≤N symbols cross the boundary of two adjacent time slots, then the S+(X-1)×L symbols are bounded by the boundary of the two time slots. Divided into 2 parts, the part before the slot boundary in these 2 parts is called "isolated symbol". In the figure, 1 uplink scheduling grants 6 repeated transmissions of the PUSCH. Currently, 1 time slot includes 14 symbols. If the time domain of the PUSCH indicated by the uplink scheduling grant includes 4 symbols, after 3 repeated transmissions, only 2 symbols remain in the current time slot, which is not enough to support 1 time. PUSCH repeated transmission. The two symbols are "isolated symbols".

At least two of the N PUSCHs are located in the same time slot. For example, N PUSCH transmission adopts the mini-slot level repetition method. If the terminal device can transmit PUSCH on isolated symbols, and the number of isolated symbols is different from the number of symbols included in the repeated mini-slot, each of the N PUSCHs is used to transmit uplink services There are at least two different resource units in the transport block.

Fig. 4 is the second application scenario of PUSCH used for retransmission of service data in the application method. One uplink scheduling grant indicates 2 or more PUSCH transmissions in adjacent time slots, and there is only one PUSCH transmission in each time slot. This type of repeated transmission is also called multi-segment transmission (Multi-segment transmission). The start symbol position and/or length of each repeated transmission may be different.

One uplink scheduling grants the time starting point and length of the scheduling PUSCH, and the time domain resources determined by the time and length of the PUSCH are located in two adjacent time slots. Since one PUSCH transmission cannot cross the time slot boundary, according to the uplink scheduling authorization, the terminal device repeatedly transmits the PUSCH twice in 2 time slots. Each PUSCH is called a PUSCH segment, and each PUSCH segment is used to transmit a PUSCH transport block once.

The first PUSCH and the second PUSCH are located in different time slots, and the last symbol of the first PUSCH and the first symbol of the second PUSCH are adjacent in time. For example, N PUSCH transmission adopts multi-segment transmission, and the number of resource units used to transmit uplink service transmission blocks for each N PUSCH may be different.

Fig. 5 is the third application scenario of PUSCH used for retransmission of service data. For another example, if the preset time resource options are available. Each item of the time resource alternative includes the number of repetitions of PUSCH transmission N, and the symbol start position and length used for each PUSCH transmission in N times of PUSCH repeated transmission. The control information indicates the time resource alternative index corresponding to the PUSCH. Through the alternative index, the terminal device can determine the number of repetitions of the scheduled repeated PUSCH, and the symbol position and length used for each transmission. In this way, the number of resource units each of the N PUSCHs used to transmit uplink service transmission blocks may be different.

Preset time resource options. Each item of the time resource option includes the number of repetitions of PUSCH transmission N, and the symbol start position and length (SLIV) used for each PUSCH transmission in the N times of PUSCH repeated transmission. The scheduling information indicates the time resource alternative index corresponding to the PUSCH. Through the alternative index, the terminal device can determine the number of repetitions of the scheduled repeated PUSCH, and the symbol position and length used for each transmission.

PUSCH repeated transmission can use any one or any combination of the three methods shown in FIGS. 3 to 5, or other methods can also be used.

Figure 6 is a schematic diagram of a terminal device.

Is the number of subcarriers in a resource block of symbol l; 1≤j≤N.

Preferably, the reference value determined by the processing module satisfies: N _RE (j)=min[N _RE (i)], or N _RE (j)=max[N _RE (i)], or j=i, where i=1,...,N.

As another embodiment of the terminal device processing control information, the receiving module further determines the scheduling resource allocation value of the N PUSCHs according to the control information; the processing module is further configured to The resource allocation value determines the resource quantity value. At this time, the reference value determined by the determining module is: the resource quantity value of the i-th PUSCH indicated by the control information; or the average value of the resource quantity values of the N PUSCH indicated by the control information; or , The sum of the resource quantity values of the N PUSCHs indicated by the control information. Further preferably, the scheduling resource allocation values of the N PUSCHs do not include the resource quantity values of DMRS and or PTRS in the PUSCH.

Preferably, in the terminal device, the process of the transmitting module to change the transmission power of the i-th PUSCH according to the information transmission rate is: when the information transmission rate increases, the transmission power is increased; when the information transmission rate decreases, the transmission power is decreased. Transmission power.

It should also be noted that, in the terminal device, at least two of the N PUSCHs actually occupy different amounts of resources. For example, at least 2 of the N PUSCHs are located in the same time slot; or, at least 2 of the N PUSCHs are located in different time slots and are adjacent in time.
