[0018] Figure 2 It is a structural schematic diagram of an SRS power distribution device in a partial detection scenario according to an embodiment of the present invention. DETAILED DESCRIPTION

[0019] As mentioned in the background technology, the existing SRS power allocation formula is not applicable to some detection scenarios.

[0020] Specifically, the existing SRS power allocation formula is as follows:

[0021]

[0022] Among them, P SRS,b,f,c (i,q s ,l) is the SRS at transmission time i, index number q s The actual power of the SRS resource set and the SRS power control adjustment state with index number l when transmitted on the activated uplink part bandwidth b of the carrier f of the serving cell c; CMAX,f,c (i) is the maximum output power configured by the user on carrier f of serving cell c; P O_SRS,b,f,c (q s ) is a high-level parameter configured for the activated uplink bandwidth b on the carrier f of the serving cell c; μ is the preset SCS threshold; M SRS,b,f,c (i) is the first coefficient; α SRS,b,f,c (q s ) is the activated uplink bandwidth b of carrier f of serving cell c and the index number is q sThe high-level parameters of the SRS resource set configuration; PL b,f,c (q d ) is the downlink path loss estimation, which can be specifically obtained by receiving the index number q d The reference signal resources are used to calculate; h b,f,c (i, l) is the SRS power adjustment state with index number l on the activated uplink part bandwidth b of the carrier f of the serving cell c at the transmission timing i.

[0023] When calculating the power of PUSCH, the first coefficient M SRS,b,f,c (i) The statistics are the number of RBs actually occupied by SRS. After the protocol supports partial detection, the first coefficient M is not excluded. SRS,b,f,c (i) will still represent the number of RBs actually transmitted by SRS. According to this logic, the calculation of SRS power using the existing SRS power allocation formula will not lead to an improvement in PSD. In fact, due to the reduction in the number of RBs actually transmitted by SRS in some detection scenarios, the calculated SRS power will actually decrease.

[0024] To solve the above technical problems, an embodiment of the present invention provides an SRS power allocation method in a partial detection scenario, including: adjusting the coefficient used in SRS power allocation according to the partial bandwidth and the overall bandwidth detected by the partial detection; and performing SRS power allocation based on the adjusted coefficient.

[0025] The bandwidth range area corresponding to the overall bandwidth may refer to the frequency band between the RB with the largest index number and the RB with the smallest index number occupied by the SRS resource in the frequency domain. The partial detection refers to that some RBs or REs that should send SRS resources in the transmission resources occupied by the SRS resources no longer send SRS resources.

[0026] This implementation scheme can avoid SRS power reduction in partial detection scenarios. Specifically, the coefficients to be used when SRS power allocation are adjusted according to the partial bandwidth and the overall bandwidth to ensure that the final allocated SRS power is at least not less than the power allocated when detecting according to the overall bandwidth. As a result, power can be concentrated on the RB detected during partial detection, preventing power jumps, reducing the difficulty of hardware implementation, and improving PSD.

[0027] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] Figure 1 It is a flow chart of an SRS power allocation method in a partial detection scenario according to an embodiment of the present invention.

[0029] This implementation can be executed by the user equipment side, such as by the user equipment (UE). Specifically, this implementation can be executed by a chip with a power calculation function in the user equipment, or by a baseband chip in the user equipment.

[0030] refer to Figure 1 The SRS power allocation method in the partial detection scenario described in this embodiment may include the following steps:

[0031] Step S101, adjusting the coefficient used in SRS power allocation according to the partial bandwidth and the overall bandwidth detected by the partial detection;

[0032] Step S102: performing SRS power allocation based on the adjusted coefficient.

[0033] In a specific implementation, the coefficient adjusted in step S101 may be the first coefficient.

[0034] Accordingly, the step S101 may include determining the overall bandwidth as the first coefficient. That is, in this specific implementation, although partial detection is adopted, the overall SRS bandwidth is still used to calculate the SRS power.

[0035] For example, the overall SRS bandwidth is 20 RBs, and partial detection uses 10 RBs or several REs in the 20 RBs. Then, the first coefficient used in calculating the SRS power is still 20 RBs.

[0036] Further, the step S102 may include the step of calculating the actual power of the SRS based on the following formula:

[0037]

[0038] Among them, P SRS,b,f,c (i,q s ,l) is the SRS at transmission time i, index number q s The actual power of the SRS resource set and the SRS power control adjustment state with index number l when transmitted on the activated uplink part bandwidth b of the carrier f of the serving cell c; CMAX,f,c (i) is the maximum output power configured by the user on carrier f of serving cell c; P O_SRS,b,f,c (q s ) is a high-level parameter configured for the activated uplink bandwidth b on the carrier f of the serving cell c; μ is the preset SCS threshold; M SRS,b,f,c (i) is the first coefficient; α SRS,b,f,c (q s ) is the activated uplink bandwidth b of carrier f of serving cell c and the index number is q sThe high-level parameters of the SRS resource set configuration; PL b,f,c (q d ) is the downlink path loss estimation, which can be specifically obtained by receiving the index number q d The reference signal resources are used to calculate; h b,f,c (i, l) is the SRS power adjustment state with index number l on the activated uplink part bandwidth b of the carrier f of the serving cell c at the transmission timing i.

[0039] That is, after adjusting the first coefficient according to the overall bandwidth, the adjusted first coefficient is substituted into the above formula to calculate and obtain the actual power of the SRS.

[0040] In a specific implementation, the step S101 may include the step of: amplifying a second coefficient according to a correlation relationship between the partial bandwidth and the overall bandwidth, wherein the second coefficient is used to determine a complex sequence mapped to a physical resource.

[0041] Specifically, the second coefficient can be applied to the following resource mapping formula:

[0042]

[0043] in, Indicates that at index number p i The subcarrier index number on the antenna port is At the same time, the OFDM symbol index is l′+l 0 The sequence mapped on the RE of ap Indicates the number of SRS antenna ports; β SRS is the second coefficient; The index number is p i The original mapping sequence on the antenna port; Indicates the frequency domain starting position of SRS; l 0 Indicates the time domain starting position of SRS; K TC Indicates the comb number, which can be configured by higher-layer signaling; Where m SRS,b It can represent the overall bandwidth of SRS. Indicates the number of subcarriers in 1 RB; Indicates the number of OFDM symbols occupied by SRS resources.

[0044] The above resource mapping formula can be used to determine the complex sequence actually mapped to the resource element. By adjusting the second coefficient, the complex sequence actually mapped to the resource element can be adjusted. Since the square of the complex modulus is the power, the SRS power can also be adjusted by adjusting the complex sequence. For more information about the resource mapping formula, refer to the relevant description in the existing protocol 38.211.

[0045] Furthermore, the second coefficient may be adjusted according to the proportion of the partial bandwidth in the overall bandwidth, thereby adjusting the output result of the resource mapping formula.

[0046] For example, if the partial bandwidth accounts for half of the total bandwidth, the second coefficient can be multiplied by The descendants enter the above formula.

[0047] In a variation, the second coefficient may not be scaled up in equal proportion. For example, if the partial bandwidth accounts for one quarter of the overall bandwidth, the second coefficient may be multiplied by 2 and then inserted into the above formula.

[0048] From the above, the present implementation scheme can avoid SRS power reduction in partial detection scenarios. Specifically, the coefficients to be used when SRS power allocation are adjusted according to the partial bandwidth and the overall bandwidth to ensure that the final allocated SRS power is at least not less than the power allocated when detecting according to the overall bandwidth. In this way, the power can be concentrated on the RB detected during partial detection, preventing power jumps, reducing the difficulty of hardware implementation, and improving PSD.
