This application claims the priority of a Chinese patent application filed with the State Intellectual Property Office of China on February 16, 2022, with the application number 202210143492.4 and the title of the application "A method and related device for uplink signal transmission", the entire contents of which are incorporated by reference in this application.

technical field

The present application relates to the technical field of communications, and in particular to an uplink signal transmission method and a related device.

Background technique

In future communications such as the fifth generation (5th Generation, 5G) mobile communications, new frequency bands such as millimeter waves have been introduced. The communication frequency in mobile communication such as 4th Generation (4G) is high, so when this new frequency band is used for communication, the transmission loss is greater, and the difference between uplink and downlink power is more obvious. In addition, future communications such as 5G mobile communications also use flexible uplink and downlink time slot ratios. Usually, downlink needs more than uplink, so that the uplink and downlink time slot ratio tends to be allocated more to downlink, which in turn exacerbates the uplink and downlink gap. The phenomenon of balance.

However, many applications (such as live video, etc.) will generate uplink traffic of the same magnitude as downlink, and such applications require the network to have a strong uplink coverage capability.

In an optional implementation manner, the reserved subcarrier information or reserved physical resource block (physical resource block, PRB) information is configured by the network device, or is predefined, or the network device passes downlink control information ( Indicated by downlink control information, DCI). That is to say, the network device can configure the number of reserved subcarriers and/or the relative frequency domain position relationship of the reserved subcarriers to the terminal device through the configuration information, or configure the number of reserved PRBs and/or the relative frequency of the reserved PRBs. Domain location relationship. Optionally, the network device and the terminal device may predefine the number of reserved subcarriers and/or the relative frequency domain position relationship of reserved subcarriers, or predefine the number of reserved PRBs and/or the relative frequency domain of reserved PRBs Positional relationship. Optionally, the network device indicates to the terminal device the number of reserved subcarriers and/or the relative frequency domain position relationship of the reserved subcarriers through the DCI, or indicates the number of reserved PRBs and/or the relative frequency domain of the reserved PRBs Positional relationship. The three manners can all enable the terminal equipment to determine reserved subcarrier information or reserved PRB information.

It can be understood that both the number of reserved subcarriers and the relative frequency domain position relationship of the reserved subcarriers in the reserved subcarrier information are configured by the network device, or both are predefined by the network device and the terminal device. Optionally, the number of reserved subcarriers in the reserved subcarrier information is configured by the network device, and the relative frequency domain position relationship of the reserved subcarriers is predefined by the network device and the terminal device. Optionally, the number of reserved subcarriers in the reserved subcarrier information is predefined by the network device and the terminal device, and the relative frequency domain position relationship of the reserved subcarriers is configured by the network device.

Similarly, the number of reserved PRBs in the reserved PRB information and the relative frequency domain position relationship of the reserved PRBs are both configured by the network device. Optionally, one of the number of reserved PRBs and the relative frequency domain position relationship of the reserved PRBs in the reserved PRB information is configured by the network device, and the other is predefined by the network device and the terminal device.

Optionally, the network device indicates to the terminal device whether there are reserved subcarriers, the number of reserved subcarriers, and the relative frequency domain positions of the reserved subcarriers through DCI information in a physical downlink control channel (PDCCH). One or more items of , or indicate whether there is one or more items of reserved PRBs, the number of reserved PRBs, and the relative frequency domain positions of reserved PRBs. Therefore, the terminal device can determine the number of reserved subcarriers and/or the relative number of reserved subcarriers through the DCI. For the positional relationship in the frequency domain, or determine the number of reserved PRBs and/or the relative positional relationship in the frequency domain of the reserved PRBs.

When the network device configures different information for the terminal device, or when the network device and the terminal device predefine different information, or when the network device indicates different information through DCI, the terminal device determines the number of reserved subcarriers or the number of reserved PRBs. Are not the same. The following describes different implementation manners for the terminal device to determine the number of reserved subcarriers or the number of reserved PRBs:

Manner 1. The terminal device determines the number of reserved subcarriers based on the number of PRBs and the first scaling factor, or determines the number of reserved PRBs based on the number of PRBs and the second scaling factor.

Wherein, the first proportional coefficient is a proportional coefficient between the number of reserved subcarriers and the number of PRBs, and the second proportional coefficient is a proportional coefficient between the number of reserved PRBs and the number of PRBs. The PRB is a PRB used to transmit a physical uplink shared channel (PUSCH). The PRB is configured by the network device.

It can be understood that when the terminal device is configured with the first proportional coefficient by the network device, or the terminal device and the network device pre-define the first proportional coefficient, or the network device indicates the first proportional coefficient to the terminal device through DCI, the terminal device based on the The number of reserved subcarriers is determined based on the number of PRBs for transmitting the PUSCH and the first scaling factor. That is, the terminal device determines that the number of reserved subcarriers is equal to the product of the number of PRBs used to transmit the PUSCH and the first proportional coefficient.

Optionally, when the terminal device is configured with the second scaling factor by the network device, or the terminal device and the network device pre-define the second scaling factor, or the network device indicates the second scaling factor to the terminal device through DCI, the terminal device The number of reserved PRBs is determined based on the number of PRBs for transmitting the PUSCH and the second proportional coefficient. That is, the terminal device determines that the number of reserved PRBs is equal to the product of the number of PRBs used to transmit the PUSCH and the second proportional coefficient.

Exemplarily, the first scaling factor configured by the network device for the terminal device is 10%, and the number of PRBs used to transmit PUSCH is 200, then the terminal device determines that the number of reserved subcarriers is 200*10%, which is 20.

In another optional implementation manner, when the terminal device is configured with multiple first proportional coefficients, or when the terminal device and the network device pre-define multiple first proportional coefficients, the terminal device can Order to determine the first scaling factor for determining the number of reserved subcarriers. The signaling may be media access control-control element (media access control-control element, MAC-CE) signaling, DCI signaling, and the like. Therefore, the terminal device can determine the number of reserved subcarriers based on the first scaling factor indicated by the network device and the number of PRBs used to transmit the PUSCH.

Similarly, when the terminal device is configured with a plurality of second proportional coefficients, or when the terminal device and the network device pre-define a plurality of second proportional coefficients, the terminal device may also determine the predetermined ratio by signaling from the network device. Reserve the second proportional coefficient of the number of PRBs. Therefore, the terminal device may determine the number of reserved PRBs based on the second scaling factor indicated by the network device and the number of PRBs used for transmitting the PUSCH.

Exemplarily, the first ratio factor for the terminal device to be configured by the network device includes 5%, 10%, 15%, and 20%. The network device indicates to the terminal device that the first proportional coefficient for determining the number of reserved subcarriers is 20% through the DCI signaling. network device If the number of PRBs configured to transmit the PUSCH is 200, the terminal device determines that the number of reserved subcarriers is 200*20%, that is, 40.

Mode 2. The number of reserved subcarriers is one of one or more values of reserved subcarriers; or, the number of reserved PRBs is one of one or more values of reserved PRBs.

In an optional implementation, when the terminal device is configured with a reserved subcarrier value, or when the terminal device and the network device pre-define a reserved subcarrier value, or the network device indicates to the terminal device through DCI When a number of reserved subcarriers is specified, the number of reserved subcarriers is equal to the number of reserved subcarriers. When the terminal device is configured with a reserved PRB value, or when the terminal device and the network device pre-define a reserved PRB value, or when the network device indicates a reserved PRB value to the terminal device through DCI, the reserved The number of PRBs is equal to the value of the reserved PRBs.

Exemplarily, the number of reserved subcarriers configured by the network device for the terminal device through the configuration information is a1, and the terminal device determines that the number of reserved subcarriers is equal to a1.

In another optional implementation, when the terminal device is configured with multiple reserved subcarrier values, or when the terminal device and the network device pre-define multiple reserved subcarrier values, the network device can also Command (for example, MAC-CE signaling or DCI signaling) indicates to the terminal device one of the values of multiple reserved subcarriers. Alternatively, when the terminal device is configured with multiple reserved PRB values, or when the terminal device and the network device pre-define multiple reserved PRB values, the network device may also indicate multiple reserved PRB values to the terminal device through signaling one of the values. Therefore, the terminal device can determine the number of reserved subcarriers or the number of reserved PRBs based on the value indicated by the network device.

Exemplarily, the number of reserved subcarriers configured by the terminal device includes a1, a2, a3, and a4, and the network device indicates a4 to the terminal device through DCI signaling, then the terminal device determines that the number of reserved subcarriers is equal to a4.

Method 3. The terminal device determines the number of reserved subcarriers based on the value range of the number of PRBs used to transmit PUSCH, or determines the number of reserved PRBs based on the value range of the number of PRBs used to transmit PUSCH .

In an optional implementation, when the terminal device is configured with one or more values of reserved subcarriers and the value range of PRB corresponding to each value of reserved subcarriers, or the terminal device and the network device pre-define When the value range of one or more reserved subcarriers and the PRB corresponding to each reserved subcarrier value is specified, or the network device indicates multiple reserved subcarrier values and each reserved subcarrier value to the terminal device through DCI When reserving the value range of the PRB corresponding to the number of subcarriers, it indicates that the value range of different PRBs corresponds to a value of the number of reserved subcarriers. Therefore, the terminal device can determine the number of reserved subcarriers based on the value range to which the number of PRBs used to transmit the PUSCH belongs.

In another optional implementation, when the terminal device is configured with one or more reserved PRB values and the value range of PRB corresponding to each reserved PRB value, or the terminal device and the network device pre-define one or more reservations PRB values and the PRB value range corresponding to each reserved PRB value, or the network device indicates to the terminal device one or more reserved PRB values and the PRB corresponding to each reserved PRB value to the terminal device When the value range of , it indicates that the value range of different PRBs corresponds to a reserved PRB value. Therefore, the terminal device can determine the number of reserved PRBs based on the value range to which the number of PRBs used to transmit the PUSCH belongs.

Exemplarily, the number of reserved subcarriers configured by the network device for the terminal device includes a1, a2, a3, and a4, and the value range of the PRB used to transmit the PUSCH corresponding to each reserved subcarrier value is as follows Table 1 shown. It can be seen from Table 1 that when the value ranges of PRBs used to transmit the PUSCH are different, the number of reserved PRBs is different. If the terminal device determines that the number of PRBs used to transmit the PUSCH is 160, the terminal device determines that the number of reserved subcarriers is a3.

Table 1

It can be seen that the terminal device can flexibly determine the number of reserved subcarriers or the number of reserved PRBs based on different methods.

In an optional implementation, if the number of reserved subcarriers or the number of reserved PRBs determined by the terminal device does not satisfy 2 ^α2 3 ^α3 5 ^α5 , the actual number of reserved subcarriers or reserved PRBs The number is min(n,2 ^α2 3 ^α3 5 ^α5 ), n is the determined number of reserved subcarriers or the number of reserved PRBs, n is a positive integer, and α2, α3, and α5 are integers greater than or equal to zero . That is to say, if the number of reserved subcarriers or the number of reserved PRBs determined by the terminal device does not satisfy 2 ^α2 3 ^α3 5 ^α5 , then the number of reserved subcarriers or the number of reserved PRBs satisfies the condition: min The minimum value of (n,2 ^α2 ·3 ^α3 ·5 ^α5 ).

It can be understood that the relative frequency domain position relationship of the reserved subcarriers refers to the relationship between the frequency domain resource positions of the reserved subcarriers and the frequency domain resource positions of the frequency domain resources allocated to the PUSCH by the network equipment, and the relative frequency domain resource positions of the reserved PRBs The frequency domain position relationship refers to the relationship between the frequency domain resource position of the reserved PRB and the frequency domain resource position of the frequency domain resource allocated to the PUSCH by the network device.

It can be seen that the relative frequency domain position relationship of the reserved subcarriers or the relative frequency domain position relationship of the reserved PRB is determined based on the frequency domain resources allocated to the PUSCH by the network equipment.

In an optional implementation manner, the reserved subcarrier frequency domain resource or the reserved PRB frequency domain resource is located on a resource other than the frequency domain resource allocated to the PUSCH by the network device. In another optional implementation manner, since the frequency domain resources allocated by the network device to PUSCH include frequency domain resources for transmitting PUSCH and reserved frequency domain resources, the reserved subcarriers or reserved PRBs can also be located in the on the reserved resources in the frequency domain resources of the PUSCH.

The following describes when the reserved subcarriers or reserved PRBs are located on resources other than the frequency domain resources allocated by the network equipment to PUSCH, and when the reserved subcarriers or reserved PRBs are located on the frequency domain resources allocated by the network equipment to PUSCH. When using resources, the relative frequency domain position relationship of the reserved subcarriers or the relative frequency domain position relationship of the reserved PRB are implemented as follows:

1. The reserved subcarriers or reserved PRBs are located on resources other than the frequency domain resources allocated to the PUSCH by the network equipment.

1.1. The starting position of the reserved subcarrier or the reserved PRB is adjacent to the ending position of the frequency domain resources allocated by the network equipment to the PUSCH.

It can be understood that the reserved subcarriers or reserved PRBs are located on frequency domain resources with a higher frequency than the frequency domain resources allocated to the PUSCH.

The frequency domain resource positions of reserved subcarriers or reserved PRBs are R(M+1)-R(M+n), where n is the number of reserved subcarriers or reserved PRBs, and n is a positive integer.

It can be seen that the start position R(M+1) of the reserved subcarrier or the reserved PRB is adjacent to the end position R(M) of the frequency domain resource allocated by the network device to the PUSCH. That is to say, the reserved subcarriers or reserved PRBs are located in high frequency domain positions outside the frequency domain resources allocated to the PUSCH by the network equipment.

1.2. The end position of the reserved subcarrier or the reserved PRB is adjacent to the start position of the frequency domain resources allocated by the network equipment to the PUSCH.

It can be understood that the reserved subcarriers or reserved PRBs are located on frequency domain resources lower in frequency than the frequency domain resources allocated to the PUSCH.

The frequency domain resource positions of reserved subcarriers or reserved PRBs are R(K-n)˜R(K-1), where n is the number of reserved subcarriers or reserved PRBs, and n is a positive integer.

It can be seen that the end position R(K-1) of the reserved subcarrier or the reserved PRB is adjacent to the start position R(K) of the frequency domain resource allocated to the PUSCH by the network device. That is to say, the reserved subcarriers or reserved PRBs are located in low frequency domain positions outside the frequency domain resources allocated to the PUSCH by the network equipment.

1.3. The start position of a part of the reserved subcarriers or reserved PRBs is adjacent to the end position of the frequency domain resources allocated by the network equipment to PUSCH, and the end position of the other part is adjacent to the start of the frequency domain resources allocated by the network equipment to PUSCH The location is adjacent.

It can be understood that a part of the reserved subcarriers or reserved PRBs is located in a frequency domain resource with a higher frequency than the frequency domain resources allocated to the PUSCH, and another part is located in a frequency domain with a lower frequency than the frequency domain resources allocated to the PUSCH. resources.

Exemplarily, as shown in FIG. 5, the positions of the frequency domain resources allocated to PUSCH by the network equipment are R(K)~R(M), and R(K) is the lowest position in the frequency domain among the frequency domain resources allocated to PUSCH, R(M) is the highest position in the frequency domain among the frequency domain resources allocated to the PUSCH. The resource positions of reserved subcarriers or reserved PRBs are R(M+1)~R(M+s) and R(K-t)~R(K-1), s+t=n, n is reserved subcarriers number or the number of reserved PRBs. s, t, n are positive integers.

It can be seen that the s reserved subcarriers in the reserved subcarriers are located on frequency domain resources higher than the end position of the frequency domain resources allocated to PUSCH, and the other t reserved subcarriers are located on frequency domain resources higher than the frequency domain resources allocated to PUSCH. The starting position of the resource is lower than the frequency domain resource; or, the s reserved PRBs in the reserved PRB are located on the frequency domain resource higher than the end position of the frequency domain resource allocated to PUSCH, and the other t reserved PRB PRBs are located on lower frequency domain resources than those allocated to PUSCH.

In an optional implementation manner, part of the above-mentioned reserved subcarriers is reserved subcarriers for half of the reserved subcarriers, and another part is reserved subcarriers for the other half of the reserved subcarriers; or, reserved A part of the PRBs reserves PRBs for half of the reserved PRBs, and another part reserves PRBs for the other half of the reserved PRBs.

That is to say, half of the reserved subcarriers are located on frequency domain resources higher than the end position of frequency domain resources allocated to PUSCH, and the other half of the reserved subcarriers are located on frequency domain resources higher than the end position of frequency domain resources allocated to PUSCH. or, half of the reserved PRBs are located on frequency domain resources higher than the end position of the frequency domain resources allocated to PUSCH, and the other half of the reserved PRBs are located on the allocated The starting position of the frequency domain resources allocated to the PUSCH is on the lower frequency domain resources. Exemplarily, s=t=n/2 in the above-mentioned FIG. 5 .

2. The frequency domain resources of the reserved subcarriers or the frequency domain resources of the reserved PRBs are located on resources within the frequency domain resources allocated to the PUSCH by the network equipment.

2.1. The end position of the reserved subcarrier or the reserved PRB is the same as the end position of the frequency domain resources allocated by the network equipment to the PUSCH.

It can be seen that the reserved subcarriers or reserved PRBs are located on the high frequency domain resources within the frequency domain resources allocated to the PUSCH by the network equipment.

Exemplarily, as shown in FIG. 6, the positions of the frequency domain resources allocated to PUSCH by the network equipment are R(K)~R(M), and R(K) is the lowest position in the frequency domain among the frequency domain resources allocated to PUSCH, R(M) is the highest position in the frequency domain among the frequency domain resources allocated to the PUSCH. The frequency domain resource positions of reserved subcarriers or reserved PRBs are R(M-n+1)-R(M), where n is the number of reserved subcarriers or reserved PRBs, and n is a positive integer. Therefore, among the frequency domain resources allocated to the PUSCH by the network device, the positions of the frequency domain resources actually used for transmitting the PUSCH are R(K)˜R(M-n).

2.2. The starting position of the reserved subcarrier or the reserved PRB is adjacent to or the same as the starting position of the frequency domain resource allocated to the PUSCH by the network device.

Understandably, the reserved subcarriers or reserved PRBs are located on low frequency domain resources within the frequency domain resources allocated to the PUSCH by the network device.

Exemplarily, as shown in FIG. 7, the positions of the frequency domain resources allocated to PUSCH by the network equipment are R(K)~R(M), and R(K) is the lowest position in the frequency domain among the frequency domain resources allocated to PUSCH, R(M) is the highest position in the frequency domain among the frequency domain resources allocated to the PUSCH. The frequency domain resource positions of reserved subcarriers or reserved PRBs are R(K)˜R(K+n-1), n is the number of reserved subcarriers or reserved PRBs, and n is a positive integer. Therefore, among the frequency domain resources allocated to the PUSCH by the network device, the positions of the frequency domain resources actually used for transmitting the PUSCH are R(K+n)˜R(M).

The end position of a part of the reserved subcarrier or reserved PRB is adjacent to or the same as the end position of the frequency domain resource allocated to PUSCH by the network device, and the start position of the other part is the same as the end position of the frequency domain resource allocated to PUSCH by the network device.

R(M) is the highest position in the frequency domain among the frequency domain resources allocated to the PUSCH. The frequency domain resource positions of a part of the reserved subcarriers or reserved PRBs are R(M-s+1)~R(M), and the frequency domain resource positions of the other part are R(K)~R(K+t-1 ), s+t=n, n is the number of reserved subcarriers or the number of reserved PRBs. s, t, n are positive integers. Therefore, among the frequency domain resources allocated to the PUSCH by the network device, the frequency domain resources actually used for transmitting the PUSCH are R(K+t)˜R(M−s).

Signal on PRB The uplink signal superimposed with the data signal.

In uplink transmission, higher maximum power reduction (maximum power reduction, MPR) or peak-to-average ratio (peak to average radio, PAR) will cause the amplifier to waste too much energy, and the signal will produce obvious in-band distortion and out-of-band radiation. Therefore, the hardware cost of the terminal device is relatively high. In addition, the bit error rate at the receiving end will increase, thereby affecting uplink transmission performance, that is, affecting uplink coverage.

It can be seen that the uplink signal sent by the terminal device is a signal obtained by superimposing a signal on a reserved subcarrier or a reserved PRB and a data signal. This method can reduce the peak value of the uplink signal, that is, reduce the PAR or MPR of the uplink signal, thereby enhancing the uplink coverage.

It can be seen that the peak value of the superimposed uplink signal (x+c) is much smaller than the peak value of the data signal x, that is, compared with the original uplink signal x, the peak value of the uplink signal is reduced, which can reduce PAR or MPR, thereby enhancing uplink coverage.

It can be seen that in the embodiment of the present application, the terminal device sends the uplink signal based on the reserved subcarrier information or the reserved PRB information. That is, the terminal device sends the uplink signal based on the determined reserved subcarriers or reserved PRBs. This method enables the uplink signal sent by the terminal device to be a superimposed signal of a data signal and a reserved subcarrier, or a signal of a superimposed signal of a data signal and a signal on a reserved PRB, thereby reducing the peak value of the uplink signal, thereby enabling Reduce the peak-to-average ratio of uplink signals and enhance uplink coverage.
