This application does not limit its specific implementation method. For example, predefined can refer to what is defined in the protocol. It should also be understood that in the embodiments of the present application, the “protocol” may refer to a standard protocol in the field of communications, for example, it may include LTE protocols, NR protocols, and related protocols used in future communication systems, and this application does not limit this.

[0052] In some embodiments, the transmit power of a terminal device is controlled by a network device. In some embodiments, separate transmit power control methods are provided for the Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), Sounding Reference Signal (SRS), Demodulation Reference Signal (DMRS), and Phase Tracking Reference Signal (PTRS).

[0053] The following uses PUSCH as an example to illustrate the transmit power control of the terminal device, but the present application is not limited to this. The transmit power control of other signals listed above (such as PUCCH, SRS, DMRS or PTRS, etc.) can refer to the relevant protocols, and the embodiments of the present application do not list them one by one.

[0054] The transmit power control of PUSCH is obtained by the following formula (1):

[0055] Wherein, b represents the active uplink bandwidth part (Band Width Part, BWP); f represents the carrier; c represents the serving cell; i represents the PUSCH transmission occasion; j represents the parameter set configuration index; q represents the number of active UL BWPs; d represents the reference signal (RS) resource index; μ corresponds to the subcarrier spacing.

[0056] P CMAX,f,c (i) is the configurable maximum transmit power of the terminal device; P O_PUSCH,b,f,c (j) is a reference target power value configured for network equipment, which is P O_NOMINAL_PUSCH,f,c (j) (target power value applicable to all UEs in the cell) and P O_UE_PUSCH,b,f,c (j) (target power value for a specific UE); is the number of RB resources used by the terminal device for uplink transmission; α b,f,c (j) is the weighted value of path loss (PL), which is also a parameter of network configuration; PL b,f,c (qd ) is the downlink path loss between the terminal device and the network device; Δ TF,b,f,c (i) is a parameter used to adjust power according to the modulation and coding scheme currently used by the terminal device; f b,f,c (i, l) is a parameter that the network device can use to control the terminal device to increase or decrease the transmission power in real time through closed-loop power control parameters.

[0057] From the above formula, it can be seen that the value of the transmit power will be affected by PL b,f,c (q d )’s impact.

[0058] Power headroom (PH) is the maximum transmit power that can be configured by the terminal device (i.e. the P CMAX,f,c (i)) and the target transmit power of the terminal device (i.e., the P PUSCH,b,f,c (i,j,q d ,l)Here abbreviated as P target ). In the implementation process, P CMAX,f,c (i) You can use P cmax In the implementation process, P PUSCH,b,f,c (i,j,q d ,l) can use P target Or you can use other letters instead. For example, PH=P cmax -P target .

[0059] In some embodiments, the PH is reported via MAC layer signaling. For example, a terminal device may report first information, which may include a Medium Access Control Element (MAC CE). Optionally, the MAC CE may be a PHR MAC CE. Optionally, the PHR MAC CE may be a single-entry PHR MAC CE (also referred to as a fixed-size MAC CE) or a multi-entry PHR MAC CE (also referred to as a variable-size MAC CE).

[0060] Figure 2 is a schematic diagram of the format of a MAC CE provided in an embodiment of the present application, and Figure 3 is a schematic diagram of the format of another MAC CE provided in an embodiment of the present application. The MAC CE format in Figure 2 is a fixed-size MAC CE format, and the MAC CE format in Figure 3 is a variable-size MAC CE format. In the MAC CE formats in Figures 2 and 3, one row corresponds to one byte.

[0061] C xThe field can be used to indicate whether the secondary cell (SCell) with index number x reports the power headroom (PH); the R field is a reserved bit; the P field is used to indicate whether power fallback is applied; the value of the V field can be 0 or 1; when V is 1, it is used to indicate that the corresponding PH is the PH calculated based on the reference format; when V is 0, it is used to indicate that the corresponding PH is the PH calculated based on the actual transmission; the maximum permissible radiation (MPE) is used to determine whether the impact of terminal equipment radiation on the human body meets the standard. CMAX,f,c 、P CMAX,f,c 1. P CMAX,f,c 2. P CMAX,f,c 3. P CMAX,f,c The m field is used to indicate the maximum transmit power of the corresponding cell.

[0062] The PH (Type 1, Primary Cell (PCell)) field is used to indicate the PH of the PCell under Type 1.

[0063] The PH (Type 2, SpCell of other MAC entities) field is used to indicate the PH of the SpCell of other MAC entities under Type 2. The SpCell is a PCell + a Primary Secondary Cell (PSCell).

[0064] The PH (Type X, Serving Cell 1) field is used to indicate the PH of Serving Cell 1 under Type X. The value of X can be 1 or 3.

[0065] The PH (Type X, Service Cell n) field is used to indicate the PH of Service Cell n under Type X. The value of X can be 1 or 3. n is an integer greater than 1 and is the index number of the service cell.

[0066] Optionally, there may be other PH domains in the fixed-size MAC CE or the variable-size MAC CE. For example, the other PH domains may include at least one of the following: a PH (type 2, PCell) domain, used to indicate the PH of the PCell under type (Type) 2; a PH (type 2, PUCCH SCell) domain, used to indicate the PH of the SCell configured with PUCCH under Type 2; a PH (type 2, PSCell) domain, used to indicate the PH of the PSCell under Type 2, etc. The embodiments of the present application are not limited to this.

[0067] In some embodiments, Type 1 may refer to a PH when only PUSCH is currently transmitted in a cell. Type 2 may refer to a PH when both PUCCH and PUSCH are currently transmitted in a cell. Type 3 may refer to a PH when SRS is currently transmitted in a cell.

[0068] It should be noted that although Figures 2 and 3 show two schematic diagrams of the format of MAC CE, the embodiments of the present application are not limited thereto. Any format of MAC CE should be within the scope of protection of the present application. For example, in other embodiments, MAC CE may have other formats. For example, MAC CE may include one byte, or MAC CE may include multiple bytes and C x The value of x ranges from 1 to 31.

[0069] In formula (1), PL in uplink transmission power control is b,f,c (q d ) is the downlink path loss value, that is, the path loss from the network device to the terminal device, which includes at least one of the following: spatial propagation loss, network device transmit antenna gain, terminal device receive antenna loss, etc., and the path loss is applied to the uplink transmit power P of the terminal device. target Calculation. Optionally, in any embodiment of the present application, the network device transmit antenna gain can be understood as, or can be referred to as, or can be, the network device transmit antenna loss. For example, if the network device transmit antenna gain is -A dB, then the network device transmit antenna loss is A dB.

[0070] Figure 4 is a schematic diagram of a downlink path loss provided in an embodiment of the present application. As shown in Figure 4, the downlink path loss includes the base station antenna (i.e., the base station transmitting antenna) gain, spatial propagation loss, and terminal device antenna (i.e., the terminal device receiving antenna) loss.

[0071] However, the downlink path loss of a terminal device may not be equal to the uplink path loss. For example, in the frequency division duplex (FDD) band, the uplink and downlink operate at different frequencies, resulting in different propagation losses. Furthermore, the transmit and receive antennas of a terminal device may differ. For example, a terminal device may have more receive antennas than transmit antennas.

[0072] Figure 5 is a schematic diagram illustrating the difference between the transmit and receive antennas of a terminal device provided in an embodiment of the present application. As shown in Figure 5, the terminal device may have eight receive antennas and two transmit antennas, i.e., the terminal device may be a 2T8R terminal device. In this case, the downlink antenna reception performance of the terminal device is better than the uplink transmit antenna performance, and this difference increases as the number of receive antennas increases.

[0073] It should be noted that Figure 5 only illustrates the number of receiving antennas and transmitting antennas of a terminal device. The embodiments of the present application do not limit the number of receiving antennas and transmitting antennas of the terminal device. For example, the number of receiving antennas of the terminal device can be other numbers, and illustratively, the number of receiving antennas of the terminal device can be 2, 4, or 16. For example, the number of transmitting antennas of the terminal device can be other numbers, and illustratively, the number of transmitting antennas of the terminal device can be 1, 4, or 8, etc.

[0074] In formula (1), the transmit power of the terminal device is determined by the downlink path loss, and the downlink path loss of the terminal device may not be equal to the uplink path loss of the terminal device. Therefore, there is a certain deviation in the transmit power control of the current terminal device, which makes the reported PH deviate from the actual PH of the terminal device to a certain extent, causing the network device to schedule the transmit power of the terminal device too much or too little, thereby affecting the uplink performance of the terminal device, for example, reducing the reliability of the uplink transmission.

[0075] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The solutions in any one or more of the above embodiments can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application.

Thus, because the first PH sent by the terminal device is determined based on the transmit power of the terminal device and the first adjustment value, the transmit power of the terminal device can be adjusted using the first adjustment value.

Optionally, the logarithmic function of the uplink operating frequency can have the same or different functional expressions as the logarithmic function of the downlink operating frequency. For example, taking the example where the logarithmic function of the uplink operating frequency can have the same functional expression as the logarithmic function of the downlink operating frequency, the logarithmic function of the uplink operating frequency is lg M1, and the logarithmic function of the downlink operating frequency is lg M2.

[0107] In some embodiments, the first result is determined based on 20×1g M1-20×1g M2. In some embodiments, the third result is determined based on 20×1g M2-20×1g M1, where M1 is the uplink operating frequency and M2 is the downlink operating frequency.

However, in other embodiments, the spatial propagation loss can also be calculated by other methods, which are not limited in this embodiment of the present application. For example, the spatial propagation loss P can be calculated by To calculate. Among them, G l P t G t G r , where P t is the transmission power; G t is the antenna gain at the transmitting end; G r is the antenna gain at the receiving end; λ is the carrier wavelength, corresponding to the operating frequency; and R is the distance between the terminal device and the network device.

Optionally, R1 and R2 can be the same or different. For another example, the spatial propagation loss L can be calculated by L = 20 × log 10 (4πd / λ). Where d is the distance between the terminal device and the network device, and λ is the carrier wavelength, which corresponds to the operating frequency. Thus, the first result is determined by L1-L2, and the third result is determined by L2-L1. L1 = 20 × log 10 (4πd1 / λ1), λ1 is determined by the uplink operating frequency, d1 represents the distance between the terminal device and the network device; L2 = 20×log 10 (4πd2 / λ2), where λ2 is determined based on the uplink operating frequency, and d2 represents the distance between the terminal device and the network device.

[0177] In the related art, the calculation of the terminal device transmission target power (i.e., the transmission power of the terminal device mentioned above) is based on the downlink path loss. However, due to the difference in uplink and downlink propagation loss, and / or the difference in loss between the terminal device's transmitting antenna and receiving antenna, the calculated terminal device target transmission power will differ from the actual transmission power, which will cause the PHR report to deviate from the actual transmission power margin of the terminal device. In order to solve this problem, the embodiment of the present application proposes to introduce a first adjustment value P delta , used to adjust the uplink transmit power.

[0178] The following describes delta :

[0179] P delta This value describes the correction applied by the terminal device to the currently calculated target transmit power. This value is affected by differences in spatial propagation loss and / or differences in transmit and receive antenna gain. The terminal device can consider all or only some of these factors when correcting its transmit power.

[0180] In some embodiments, P delta =P TxLoss -P RxLoss In other embodiments, P delta =P RxLoss -P TxLoss The following is P delta =P TxLoss -P RxLoss As an example, the communication method of this application is described.

[0181] P TxLoss and P RxLoss The spatial propagation losses and / or the transmit and receive antenna losses of the terminal equipment are taken into account.

[0182] Optionally, when considering both spatial propagation loss and terminal device antenna loss, P TxLoss = Transmitting space propagation loss + transmitting antenna loss; P RxLoss = receiving space propagation loss + receiving antenna loss.

[0183] Alternatively, when only spatial propagation loss is considered, P TxLoss = Transmitting space propagation loss; P RxLoss = Propagation loss in receiving space.

[0184] Optionally, when only the terminal device antenna loss is considered, P TxLoss = Transmitting antenna loss; P RxLoss =Receiving antenna loss.

[0185] For example, when only the spatial propagation loss is considered, if the transmission spatial propagation loss in the FDD band is X dB smaller than the reception spatial propagation loss, then P delta For example, when only the terminal device antenna loss is considered, if the terminal device's transmitting antenna loss is XdB less than the receiving antenna loss, then P delta For another example, when considering both spatial propagation loss and terminal device antenna loss, if the transmit spatial propagation loss in the FDD band is XdB less than the receive spatial propagation loss, and the transmit antenna loss of the terminal device is XdB less than the receive antenna loss, then P delta Equal to –2XdB.

[0186] The following describes delta Adjustment of the transmit power of the terminal device:

[0187] According to the relevant technology, the transmission power of the terminal device is determined to be P target In the case of , the corrected transmit power or adjusted transmit power can be P target +P delta .

[0188] P deltaThis includes the difference in uplink and downlink spatial propagation loss, and / or the difference in transmit and receive antenna loss. Optionally, in any embodiment of the present application, transmit and receive antenna losses can be understood as, referred to as, or represented by transmit and receive antenna gains. For example, a transmit antenna gain of -A dB indicates a transmit antenna loss of A dB. For another example, a receive antenna gain of -B dB indicates a receive antenna loss of B dB.

[0189] Optionally, the terminal device can obtain the spatial propagation loss as P0-RSRP (i.e., downlink spatial propagation loss) by measuring the received signal strength RSRP of the downlink reference signal (such as SSB) and the transmit signal strength P0 of the reference signal on the base station side. Optionally, in any embodiment of the present application, the received signal strength can be referred to as the received power strength, and the transmit signal strength can be referred to as the transmit power strength.

[0190] Optionally, the terminal device can calculate the difference in spatial propagation loss based on the frequency difference between the uplink and downlink. For example, the terminal device can calculate the difference in spatial propagation loss according to the spatial propagation loss formula R=32.4+20*log 10 D+20*log 10 M, calculate the spatial propagation loss of a certain operating frequency, and then determine the difference in uplink and downlink spatial propagation loss based on this formula and the uplink and downlink operating frequencies. It should be noted that the embodiment of the present application does not limit the method of calculating spatial path loss, or it can also be calculated in other ways, which will not be repeated here. Wherein, the formula R = 32.4 + 20 * log 10 D+20*log 10 Where D is the free-space propagation distance of the wireless signal in kilometers, M is the operating frequency in MHz, and R is the loss value in dB.

[0191] Optionally, the network device can measure the uplink spatial propagation loss, for example, the network device can determine it based on the SRS sent by the terminal device. However, in related art, the network device cannot determine the signal strength of the SRS sent by the terminal device, so the network device cannot measure the uplink spatial propagation loss.

[0192] In an embodiment of the present application, a terminal device is introduced to report the transmit signal strength of the SRS transmitted by the terminal device. That is, when the terminal device transmits the SRS, the transmit signal strength (SRStx) of the transmitted SRS is reported to the network device. The network device receives and measures the signal strength of the SRS to obtain the received signal strength (SRSrx). The network device can obtain the uplink propagation loss value as SRStx-SRSrx. The network device can send the uplink propagation loss value to the terminal device, so that the terminal device can obtain the uplink propagation loss value and apply the uplink propagation loss value to adjust the transmit power of the terminal device.

[0193] In some embodiments, the number of transmitting antennas of a terminal device is usually less than the number of receiving antennas, which results in the loss (or gain) of the transmitting antenna being different from that of the receiving antenna. For example, if the loss of the transmitting antenna of a terminal device is XdB less than the loss of the receiving antenna, then P delta = -XdB, etc. For the terminal device, its transmitting and receiving antenna loss (or gain) is known, and this value can be stored inside the terminal device and applied to P delta Calculation.

[0194] The following describes delta Report:

[0195] Since the transmit power of the terminal device is adjusted compared to the target transmit power obtained by the related art, it is also necessary to consider how to inform the base station of the adjustment value.

[0196] In some embodiments, the terminal device can report through PHR. delta Or use P delta The indication information is reflected in the PHR report so that the PHR can reflect the actual terminal device transmission power and margin.

[0197] In the related art, the PH of the terminal device is P cmax With P target The difference, that is, PH = P cmax -P target In the embodiment of the present application, due to the P delta The transmit power of the terminal device is adjusted so that PH=P cmax -(P target +P delta ).

[0198] In PHR reporting, P delta It is also reported to the base station for the base station to refer to the actual loss difference between uplink and downlink.

[0199] Optionally, as shown in FIG2 and FIG3, the terminal device may indicate whether the PHR is used in the reported PHR by using the reserved bit (R bit) in the MAC CE. delta Adjust the value. However, this method can only inform the base station whether the current terminal device's transmission power uses P delta Adjustment is performed, but the specific adjustment value is not told to the base station.

[0200] Optionally, the terminal device can introduce a new bit to P delta The adjusted value should be reported together.

[0201] FIG8 is a schematic diagram of the format of another MAC CE provided in an embodiment of the present application. As shown in FIG8 , the MAC CE in FIG8 is a format of a fixed-size MAC CE. In the format of the MAC CE in FIG8 , one row corresponds to one byte.

[0202] The R field is a reserved bit; the P field is used to indicate whether power fallback is applied; and the Maximum Permissible Exposure (MPE) is used to determine whether the impact of terminal equipment radiation on the human body meets the standard.

[0203] In FIG8 , the 3rd to 8th bits from left to right in the first row are used to carry the PH value, and the 3rd to 8th bits from left to right in the second row are used to carry the P cmax The 8 bits in the third row are used to carry P delta .

[0204] It should be noted that the carrier P delta The bits of P are all the bits of the third row. delta The bits can be part of the bits in the third row, or carry P delta The bits may be the second row in the MAC CE, and the third row in the MAC CE carries P cmax The embodiment of the present application is not limited to carrying P delta The position of the bit.

[0205] In some embodiments, the difference in uplink and downlink spatial propagation loss and the difference in transmit and receive antenna loss of the terminal device are usually relatively constant. These two differences are related to the operating frequency band. Therefore, the P of each frequency band can be calculated by the relatively static capability of the terminal device capability information. delta Adjust the value and report it.

[0206] In some embodiments, the above-mentioned PHR reporting method can be combined in actual transmission to indicate whether this PHR is used in the current transmission power. delta Adjust the value. Of course, you can also use the default method, such as the default method as long as the terminal device reports the P value of each frequency band.delta Adjust the value capability information, and the default terminal device will use this P when transmitting power delta Adjust the value.

[0207] The following describes delta Adjustable capabilities and base station control:

[0208] Optionally, the method for the terminal device to adjust its transmit power (by P delta Adjusting transmit power can be considered a feature. The terminal device needs to tell the base station whether it supports this feature, which is the corresponding terminal device capability. There are two ways to report this capability:

[0209] Method 1: By reporting P as described above delta Adjust the value to implicitly tell the base station that it supports this feature. At this time, it only needs to report: the P value of the terminal device in each frequency band delta value.

[0210] Method 2: Define a separate capability information. The capability information of the terminal device will include the following: whether the terminal device supports P delta Adjust the transmission power; the P of the terminal equipment in each frequency band delta value.

[0211] Optionally, in addition to the above-mentioned reporting of the terminal device capability, the base station control can be further introduced, that is, the base station determines whether the terminal device performs P control on its transmit power. delta When the base station allows the terminal device to adjust the transmit power, this feature is activated on the terminal device side, otherwise it is not activated. The specific base station control method can be defined by control signaling (RRC or MAC or DCI signaling method), for example: Activate P delta Adjustment command (EnablePdelta) or deactivate Pdelta adjustment command (DisablePdelta).

[0212] The embodiment of the present application provides a method for adjusting the transmission power. In this method, the input P delta It is used to correct the currently calculated target transmit power to overcome the difference between the target transmit power and the actual transmit power of the terminal device caused by the difference in uplink and downlink propagation loss, the difference in the transmit and receive antennas of the terminal device, and the resulting deviation of the PHR reported value from the actual transmit power margin of the terminal device. In addition, the embodiment of the present application proposes P delta The definition of, adjustment of transmit power and reporting of related signaling, etc.

[0213] In the embodiment of the present application, by introducing P deltaAdjusting the power can make the transmission power of the terminal device closer to the actual power that the terminal device needs to transmit, overcoming the difference in spatial propagation loss caused by the difference in uplink and downlink frequencies and the difference in loss caused by the difference in the transmitting and receiving antennas of the terminal device.

[0214] The communication method of the embodiment of the present application can solve the problem that the transmission power actually required by the terminal device is inconsistent with the currently calculated transmission power, and the problem that the PHR reported value is inconsistent with the actual situation.
