As shown in FIG. 1b, in the SBFD, an uplink (UL) symbol is inserted in a sub-band corresponding to a downlink (DL) symbol in a carrier bandwidth, so as to realize full duplex transmission on the symbol. That is, the SBFD symbol includes both uplink resources and downlink resources. The carrier bandwidth of the SBFD symbol can be divided into a plurality of sub-bands (SBs) in the frequency domain, and the plurality of SBs include uplink SBs and downlink SBs.
[0157] In the related art, it is simpler and more feasible for the network device 102 to implement an antenna isolation and interference self-cancellation technology, which is applicable to the network device 102 side. With the development of the terminal 101 technology, there is a demand for introducing a full duplex technology such as the SBFD on the terminal 101 side.
[0158] In the full duplex application on the terminal 101 side, the interference problem of the uplink transmission of the terminal 101 on the downlink reception of the terminal 101 needs to be solved.
[0159] The present disclosure provides a power control method suitable for full duplex communication of the terminal 101.
[0160] FIG. 2 is an interaction schematic diagram of a method for determining an uplink transmission power according to an embodiment of the present disclosure. As shown in FIG. 2, the present disclosure relates to a method for determining an uplink transmission power, and the method includes the following steps.
[0161] In step S2101, the network device 102 sends first indication information to the terminal 101.
[0162] In some embodiments, the terminal 101 receives the first indication information.
[0163] In some embodiments, the first indication information is used to indicate at least one of the following: a first threshold value, a second threshold value. The first threshold value and / or the second threshold value are used by the terminal 101 to determine an offset, and the offset is used to determine the uplink transmission power. For details, see the description of the following embodiments.
[0164] The first threshold value is a threshold value corresponding to the downlink reception quality, and the second threshold value is a threshold value corresponding to the guard interval.
[0165] In some embodiments, the network device 102 can send the first indication information through different signaling. For example, the network device 102 sends the first indication information through radio resource control (RRC) signaling or downlink control information (DCI).
[0166] In some embodiments, the step S2101 can be omitted, for example, the first threshold and / or the second threshold is defined by a protocol, or determined by the terminal 101, or is a default value.
[0167] In step S2102, the network device 102 sends second indication information to the terminal 101.
[0168] In some embodiments, the terminal 101 receives the second indication information.
[0169] In some embodiments, the second indication information is used to indicate a third threshold. Wherein, the third threshold is used by the terminal 101 to measure the size of the offset, which can be seen from the description of the following embodiments.
[0170] In some embodiments, the network device 102 can send the second indication information through RRC signaling or DCI.
[0171] In some embodiments, the network device 102 can perform steps S2101 and S2102 synchronously, for example, the network device 102 sends the first indication information or the second indication information through the same signaling.
[0172] In some embodiments, the network device 102 performs steps S2101 and S2102 respectively, for example, the network device 102 sends the first indication information or the second indication information through different signaling respectively, wherein the execution order of steps S2101 and S2102 is not limited, for example, step S2101 can be executed first or step S2102 can be executed first.
[0173] In some embodiments, the step S2102 can be omitted, for example, the third threshold can be defined by a protocol or determined by the terminal 101.
[0174] In step S2103, the terminal 101 determines the offset.
[0175] In some embodiments, the offset is used to indicate the offset of uplink power control, wherein the uplink power control represents the uplink power determined in the related manner, that is, the offset can represent the power offset between the existing uplink power.
[0176] In some embodiments, the terminal 101 supports full duplex mode, such as SBFD. For example, in combination with FIG. 1b, in the time domain unit of full duplex, the terminal 101 can perform uplink transmission in the uplink subband and perform downlink reception in the downlink subband. Wherein, the time domain unit can be a symbol.
[0177] In some embodiments, the offset is determined according to a first parameter. The first parameter is a downlink reception parameter of the terminal 101, which can be used to indicate or determine the downlink reception of the terminal 101. For example, the first parameter is used to indicate the downlink reception quality of the terminal 101, or is used to indicate the downlink reception resource configuration of the terminal 101.
[0178] In some embodiments, the first parameter comprises at least one of the following:
[0179] downlink reception quality;
[0180] gap, wherein the gap is a frequency domain interval between the downlink resource and the uplink resource in a time domain unit of full duplex.
[0181] The gap is included in the downlink reception resource configuration corresponding to the terminal 101.
[0182] In an example, the downlink reception quality can be represented by at least one of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), and signal noise ratio (SNR). In the embodiments of the present disclosure, the downlink reception quality is represented by SNR.
[0183] In an example, as shown in FIG. 1b, the gap is located between the uplink resource and the downlink resource of the SBFD symbol, or is located between the uplink sub-band and the downlink sub-band. The gap can form a certain interval between the uplink and the downlink, reduce the interference between the uplink and the downlink, and reduce the difficulty of uplink and downlink isolation of the network device 102 or the terminal 101.
[0184] In an example, the gap satisfies one of the following:
[0185] comprises at least one RB;
[0186] comprises one or more subcarriers;
[0187] in frequency units.
[0188] The gap can be configured with multiple granularities. For example, the gap is 2 RBs in RB granularity. For another example, the gap is 30 subcarriers in subcarrier granularity. For another example, the gap is several megahertz (MHz) in frequency units.
[0189] In some embodiments, the interference of uplink transmission to downlink reception is a main factor to determine the full-duplex performance of the terminal 101. When the downlink reception quality is certain, the smaller the uplink transmission power is, the smaller the interference of uplink transmission to downlink reception is. When the uplink transmission power is certain, the better the downlink reception quality is, the smaller the interference of uplink transmission to downlink reception is. Therefore, determining the uplink transmission power according to the downlink reception quality can better support the power control of the full-duplex terminal.
[0190] In some embodiments, the terminal 101 can determine the offset in various ways.
[0191] In a possible implementation, the offset has a mapping relationship with the downlink reception quality, and the mapping relationship is used to determine the offset corresponding to different downlink reception qualities; and / or, the offset has a mapping relationship with the guard interval, and the mapping relationship is used to determine the offset corresponding to different guard intervals.
[0192] In a first example, the offset has a mapping relationship with the downlink reception quality. When the downlink reception quality is different, the terminal 101 can determine the offset corresponding to different downlink reception qualities based on the mapping relationship.
[0193] In this example, the terminal 101 measures the downlink reception quality based on a first threshold value configured by the network or defined by the protocol. Taking SNR as an example to represent the downlink reception quality, the first threshold value can be SNR0.
[0194] In this example, if the downlink reception quality is greater than or equal to the first threshold value, it indicates that the downlink reception quality is good, and at this time the offset can be recorded as a first value. If the downlink reception quality is less than the first threshold value, it indicates that the downlink reception quality is poor or the downlink reception quality is bad, and at this time the offset is a second value. When the downlink reception quality is good, the influence of uplink transmission on downlink reception can be small, and the offset can be 0; when the downlink reception quality is poor, a certain offset needs to be set to reduce the uplink transmission power, so as to reduce the influence of uplink transmission on downlink reception.
[0195] In this example, the first value is 0 dB, and the second value is -2 dB. The mapping relationship between the downlink reception quality and the offset can refer to Table 1 shown below:
[0196] Table 1
[0197] In a second example, the offset has a mapping relationship with the guard interval. When the guard interval is different, the terminal 101 can determine the offset corresponding to different guard intervals based on the mapping relationship.
[0198] In this example, the terminal 101 measures the size of the guard interval based on a second threshold value configured by the network or defined by the protocol, and the second threshold value can be Gap0.
[0199] In this example, if the guard interval is greater than or equal to the second threshold, it means that the guard interval is large, and the guard interval has a good isolation effect between the uplink and the downlink. At this time, the offset is recorded as a third value. If the guard interval is less than the second threshold, it means that the guard interval is small, and the guard interval has a poor isolation effect between the uplink and the downlink. At this time, the offset is recorded as a fourth value. When the guard interval is large, the offset can be 0; and when the guard interval is small, a certain offset needs to be set to reduce the uplink transmission power, thereby reducing the influence of the uplink transmission on the downlink reception.
[0200] In this example, the third value can be the same as or different from the first value, such as 0 dB; and the fourth value can be the same as or different from the second value, such as -2 dB. The mapping relationship between the guard interval and the offset can refer to Table 2 shown below:
[0201] Table 2
[0202] In a third example, the offset needs to be determined according to the downlink reception quality and the guard interval.
[0203] In this example, the first threshold and the second threshold can refer to the description of the foregoing examples or the foregoing embodiments, which will not be described here again.
[0204] In this example, the mapping between the offset and the two can refer to Table 3 shown below:
[0205] Table 3
[0206] In this example, the downlink reception quality is greater than or equal to the first threshold, and the guard interval is greater than or equal to the second threshold. The offset is a fifth value, and the fifth value can be the same as or different from the first value, such as 0 dB.
[0207] Alternatively, the downlink reception quality is greater than or equal to the first threshold, and the guard interval is less than the second threshold. The offset is a sixth value, and the sixth value can be the same as or different from the second value, such as -2 dB.
[0208] Alternatively, the downlink reception quality is less than the first threshold, and the guard interval is greater than or equal to the second threshold. The offset is a seventh value, and the seventh value is the same as or different from the sixth value, such as -2 dB.
[0209] Alternatively, the downlink reception quality is less than the first threshold, and the guard interval is less than the second threshold. The offset is an eighth value, and the eighth value can be separately set, such as -3 dB.
[0210] In another possible implementation, the offset is determined according to the downlink reception quality and the corresponding first threshold, and / or the offset is determined according to the guard interval and the corresponding second threshold.
[0211] The first threshold and the second threshold can refer to the aforementioned examples or the aforementioned embodiment descriptions, which will not be repeated here.
[0212] In the first example, the offset is determined according to the downlink reception quality and the first threshold, for example, the offset Offset is determined according to the following manner: Offset = min(0, γ*10log(SNR / SNR0)), where SNR is the downlink reception quality, SNR0 is the first threshold. γ is a set adjustment factor, which can be set by the terminal itself.
[0213] In this example, the terminal 101 calculates and determines the offset based on the downlink reception quality and the first threshold.
[0214] In the second example, the offset is determined according to the guard interval and the second threshold, for example, the offset Offset is determined according to the following manner: Offset = min(0, γ*10log(Gap / Gap0)), where Gap is the guard interval, Gap0 is the second threshold. γ is a set adjustment factor, which can be set by the terminal itself.
[0215] In this example, the terminal 101 calculates and determines the offset based on the guard interval and the second threshold.
[0216] In the third example, the offset is determined according to the downlink reception quality, the first threshold, the guard interval and the second threshold, for example, the offset Offset is determined according to the following manner:
[0217] Offset = min(0, γ*10log(SNR*Gap / (SNR0*Gap0))), where SNR is the downlink reception quality, SNR0 is the first threshold, Gap is the guard interval, and Gap0 is the second threshold. γ is a set adjustment factor, which can be set by the terminal itself.
[0218] In this example, the terminal 101 calculates and determines the offset based on the downlink reception quality, the first threshold, the guard interval and the second threshold.
[0219] It is worth noting that step S2103 can be omitted, and the terminal 101 directly performs step S2105. For example, the terminal 101 applies the determined offset in the process of determining the uplink transmission power, and the determination of the offset depends on the hardware or algorithm implementation of the terminal 101.
[0220] In step S2104, the terminal 101 sends the auxiliary information to the network device 102.
[0221] In some embodiments, the auxiliary information includes the offset.
[0222] In some embodiments, the terminal 101 can report the determined offset to the network device 102 for reference when scheduling, so that the network device 102 can better schedule the transmission power of the terminal.
[0223] In step S2105, the terminal 101 determines the uplink transmission power according to the offset.
[0224] In some embodiments, the terminal 101 determines the offset in different scenarios according to step S2103. Alternatively, the terminal 101 directly determines the uplink transmission power based on the offset in this step S2105 based on hardware or algorithm implementation.
[0225] In some embodiments, the uplink transmission power can be any of the following corresponding uplink transmission power: physical uplink shared channel (PUSCH), physical uplink control channel (PUCCH), sounding reference signal (SRS).
[0226] Taking the determination of the uplink transmission power of the PUSCH as an example, the uplink power control of the PUSCH or the existing uplink power P PUSCHb,f,c (i,j,q d ,l) in the related art is as follows:
[0227] Wherein, P CMAX,f,c (i) is the maximum configured power, which can also be denoted as P CMAX ;
[0228] P O _PUSCHb,f,c(j) is the target power on the network device 102 side;
[0229] (i) is the occupied resource information of the transmission channel;
[0230] α b,c,f (j)·PL b,f,c (q d ) is the path loss related compensation information;
[0231] Δ TF,b,c,f (i) is the modulation and coding strategy influence factor;
[0232] f b,c,f (i,l) is the power adjustment factor or power adjustment state, which is related to the power control signaling (TPC) of the network device.
[0233] In this embodiment, when the terminal 101 determines the uplink transmission power of the PUSCH based on the offset, the uplink transmission power of the PUSCH is determined according to the offset and the above-mentioned uplink power control, for example, the offset can be added in the first term of the formula or the second term of the formula.
[0234] In some embodiments, the terminal 101 determines the maximum configured power P CMAX based on the offset, and determines the first power based on the offset; wherein the uplink transmission power is the minimum value between P CMAX and the first power.
[0235] For example, still taking the uplink transmission power of the PUSCH as an example, the first power refers to the second term or the second row in the above-mentioned formula. P CMAX is the first term or the first row in the formula.
[0236] In an example, the terminal 101 adds the determined offset when determining P CMAX , does not consider the offset when determining the first power, and then determines the uplink transmission power based on the minimum value between P CMAX and the first power.
[0237] That is:
[0238] In another example, the terminal 101 does not consider the offset when determining P CMAX , adds the determined offset when determining the first power, and then determines the uplink transmission power based on the minimum value between P CMAX and the first power.
[0239] That is:
[0240] In yet another example, the terminal 101 adds the determined offset when determining P CMAX , also needs to add the determined offset when determining the first power, and then determines the uplink transmission power based on the minimum value between P CMAX and the first power.
[0241] That is:
[0242] In some embodiments, when the terminal 101 determines the first power based on the offset, a new parameter △F FD corresponding to the introduced offset can be introduced, and the introduced offset offset is represented by the new parameter. That is, the terminal 101 determines the first power according to the offset, the network device side target power, the modulation and coding strategy influence factor and the power adjustment factor. At this time, the first power is determined by the following formula:
[0243] wherein, △F FD offset, i.e. the offset determined according to the mapping relationship or according to the formula in the above embodiments.
[0244] In some embodiments, the terminal 101 can include the offset in an existing parameter. For example, the terminal 101 determines the first power according to the target power of the network device side, a modulation and coding strategy impact factor and a power adjustment factor, wherein the modulation and coding strategy impact factor includes the offset, or the power adjustment factor includes the offset. In this case, the first power is determined by the following formula:
[0245] Compared with the existing parameters in the related art, the modulation and coding strategy impact factor Δ TF,b,c,f (i)′ includes the determined offset, i.e. Δ TF,b,c,f (i)′ = Δ TF,b,c,f (i) + offset; or the power adjustment factor f b,c,f (i, l)′ includes the determined offset, i.e. f b,c,f (i, l)′ = f b,c,f (i, l) + offset.
[0246] In the above embodiments, the terminal 101 determines the first power and / or the P CMAX After that, the uplink transmission power considering the downlink reception situation can be determined to reduce the uplink interference to the downlink.
[0247] In some embodiments, after determining the uplink transmission power, the terminal 101 can perform step S2106 or S2107.
[0248] Step S2106, the terminal 101 transmits the uplink information to the network device 102 according to the determined uplink radiation power in the time domain unit of full duplex.
[0249] In some embodiments, after the terminal 101 performs step S2103 to determine the offset, the terminal 101 can determine the relationship between the offset and a third threshold value. If the absolute value of the offset is less than the third threshold value, the terminal 101 performs step S2104 and / or S2105.
[0250] In some embodiments, step S2106 is performed when the absolute value of the offset is less than the third threshold value.
[0251] In some embodiments, the absolute value of the offset is less than the third threshold value, which indicates that the value of the offset will not affect the quality of the uplink channel due to being too large, and the terminal 101 can perform the uplink transmission.
[0252] Step S2107, the terminal 101 does not perform the uplink transmission in the time domain unit of full duplex.
[0253] In some embodiments, after determining the offset in step S2103, the terminal 101 can determine the relationship between the offset and a third threshold. If the absolute value of the offset is greater than or equal to the third threshold, the terminal 101 can directly perform step S2107, and the terminal 101 can not perform steps S2104 and / or S2105.
[0254] In some embodiments, step S2107 is performed when the absolute value of the offset is greater than or equal to the third threshold.
[0255] In some embodiments, when the absolute value of the offset is greater than or equal to the third threshold, it indicates that the value of the offset is too large, which can affect the quality of the uplink channel.
[0256] In some embodiments, the terminal 101 does not perform uplink transmission in the time domain unit of full duplex, that is, the terminal 101 does not perform full duplex communication in the time domain unit.

[0313] The embodiments of the present disclosure provide a power control method suitable for full-duplex communication. In the method, when determining the power of a transmitted signal, a terminal determines its uplink power control power according to the quality of a current received signal and / or the Gap of uplink and downlink resources. A base station can control whether a terminal performs uplink full-duplex transmission by signaling a threshold value. To facilitate understanding of the embodiments of the present disclosure, some examples are listed as follows:
[0314] Example 1:
[0315] When determining the power of a transmitted signal, a terminal determines its uplink power control power according to the quality of a current received signal and / or the Gap of uplink and downlink resources. On the basis of existing power control parameters, the influence of the quality of a current received signal is taken into account:
[0316] For example, the power of a PUSCH transmitted signal is determined (the power control of other signals such as PUCCH and SRS can refer to that of PUSCH):
[0317] As can be seen from the above formula, the size of the terminal transmit power depends on:
[0318] P O _PUSCHb,f,c(j) is the target power on the network device 102 side;
[0319] (i) is the occupied resource information of a transmission channel;
[0320] α b,c,f (j)·PL b,f,c (q d ) is path loss related compensation information;
[0321] Δ TF,b,c,f (i) is a modulation and coding strategy influence factor;
[0322] f b,c,f (i,l) is a power adjustment factor or a power adjustment state, which is related to the power control signaling (TPC) of the network device.
[0323] For example, ΔTF,b,c,f (i) or f b,c,f (i, l) considers the current received signal quality and or the gap of uplink / downlink resource to determine the final value of the above parameters.
[0324] One embodiment, as shown in Table 3, in Δ TF,b,c,f (i) or f b,c,f (i, l) adds the offset determined according to Table 3. The quality of the received signal and the size of the gap can be determined by the terminal according to whether it is greater than a certain threshold.
[0325] Wherein, the Gap can refer to Figure 1b, wherein the size of the Gap can be one of the following:
[0326] 1) in RB granularity, such as 2RB, etc.
[0327] 2) in subcarrier granularity, such as 30 subcarriers, etc.
[0328] 3) also in frequency units, such as MHz, etc.
[0329] In another embodiment, it can be calculated by the current received signal quality and / or the size of the uplink / downlink resource gap. For example:
[0330] Offset = min(0, γ*10log(SNR 当前 *Gap / (SNR0*Gap0)), wherein SNR 当前 represents the linear value of the SNR of the current downlink signal. SNR0 is the threshold of the downlink channel quality set by the terminal itself, and γ is the adjustment factor set by the terminal itself.
[0331] In an example, if the size of the uplink / downlink resource gap is not considered, i.e. only the downlink received signal quality is considered, the offset can be calculated by referring to the manner of Table 1.
[0332] In another example, when the calculation scheme is adopted, only the influence of the received signal SNR is considered in the formula. For example:
[0333] Offset = min(0, γ*10log(SNR 当前 / SNR0).
[0334] Alternatively, in an example, if the current received signal quality is not considered, i.e. only the size of the uplink / downlink resource gap is considered, the offset can be calculated by referring to the manner of Table 2.
[0335] In another example, when the calculation scheme is adopted, only the influence of the uplink / downlink resource gap is considered in the formula. For example:
[0336] Offset = min(0, γ * 10log(Gap / Gap0)).
[0337] Example 2
[0338] When determining the power of a transmitted signal, the terminal determines its uplink power control power according to the quality of a currently received signal and / or a Gap of uplink and downlink resources. A new parameter is added to the existing power control parameters, and the influence of the quality of the currently received signal is considered. For example, when determining the PUSCH transmission power, an additional parameter △F is added. FD .
[0339] In one embodiment, the first term and the second term in the calculation formula of the PUSCH transmission power in Example 1 can be added with △F FD .
[0340] wherein the determination method of △F FD may refer to the determination method of offset in Example 1, that is, can be calculated through the quality of the currently received signal and / or the Gap of uplink and downlink resources.
[0341] Example 3
[0342] If the offset value is too large, it may affect the quality of the uplink channel, and therefore the absolute value of the offset can be set to not exceed a threshold. In one embodiment, the threshold can be determined by the terminal itself, and in another embodiment, the threshold can be sent to the terminal by the base station.
[0343] When the terminal determines that the absolute value of the offset exceeds the threshold, the terminal can give up the uplink transmission, that is, does not perform full-duplex communication.
[0344] Example 4
[0345] In order for the base station to better schedule and control the transmission power of the terminal, the terminal can report the offset in Example 1 and Example 2 to the base station as auxiliary information.
[0346] The embodiments of the present disclosure also propose a device for implementing any of the above methods, for example, a device including units or modules for implementing each step performed by the terminal in any of the above methods.
