Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an information transmission method and a communication device. Background Art

[0002] When the terminal device uses the main antenna and the diversity antenna to send the reference signal, the insertion loss of the main antenna is smaller than the insertion loss of the diversity antenna. The reference signal transmission power of the diversity antenna is unbalanced with the reference signal transmission power of the main antenna, which will affect the channel estimation. Summary of the invention

[0003] The embodiments of the present application provide an information transmission method and a communication device, which can report the power difference corresponding to each diversity antenna to a network device, thereby improving the accuracy of channel estimation.

[0004] In a first aspect, an embodiment of the present application provides an information transmission method, which is applied to a terminal device, wherein the terminal device includes a main antenna and N diversity antennas, where N is an integer greater than or equal to 1; the method includes:

[0005] Sending first information, wherein the first information indicates power differences corresponding to M diversity antennas, respectively, the power difference being a power difference between a reference signal transmission power of a corresponding diversity antenna and a reference signal transmission power of a main diversity antenna, the N diversity antennas including the M diversity antennas, the M being an integer less than or equal to the N, and the M being an integer greater than or equal to 1.

[0006] Based on the description of the first aspect, the terminal device can indicate the power difference corresponding to the M diversity antennas through the first information. In other words, the terminal device reports the actual power difference corresponding to the M diversity antennas, so that the network device can compensate each diversity antenna according to the actual power difference, try to balance the power of the main diversity antenna and the diversity antenna, and improve the accuracy of channel estimation.

[0007] In an optional implementation manner, the first information includes power differences corresponding to the M diversity antennas respectively;

[0008] The power difference corresponding to one diversity antenna among the M diversity antennas occupies P bits, where P is an integer greater than or equal to 1.

[0009] By implementing this method, the power differences corresponding to the M diversity antennas can be included in the first information, and the power difference of each diversity antenna occupies a corresponding fixed P bits, which can facilitate rapid analysis to obtain the power difference corresponding to the diversity antenna.

[0010] In an optional implementation, the first information includes at least one power difference index value and a diversity antenna corresponding to each of the at least one power difference index values, and one power difference index value among the at least one power difference index value indicates a power difference.

[0011] By implementing this method, the power difference of the diversity antenna can be reported through the power difference index value, saving signaling overhead.

[0012] In an optional embodiment, the method further includes:

[0013] Measuring the reference signal transmission power corresponding to the M diversity antennas and the reference signal transmission power corresponding to the main diversity antenna, wherein the M diversity antennas are M diversity antennas associated with the reference signal rotation capability currently used by the terminal device;

[0014] The power differences corresponding to the M diversity antennas are determined according to the reference signal transmission powers corresponding to the M diversity antennas and the reference signal transmission powers corresponding to the main diversity antenna.

[0015] By implementing this method, the reference signal transmission power corresponding to the diversity antenna and the reference signal transmission power corresponding to the main antenna can be measured in real time, so as to determine the power difference corresponding to the diversity antenna based on the reference signal transmission power corresponding to the diversity antenna and the reference signal transmission power corresponding to the main antenna. Since the power difference is obtained based on the reference signal transmission power measured in real time, the accuracy of the reported power difference can be guaranteed.

[0016] In an optional embodiment, the method further includes:

[0017] Second information is sent, where the second information indicates reference signal transmission powers of the M diversity antennas and reference signal transmission powers corresponding to the main antenna.

[0018] By implementing this method, the reference signal transmission power of the diversity antenna and the reference signal transmission power corresponding to the main antenna measured in real time can be reported, so that the network side can compensate the receiving power of the diversity antenna.

[0019] In an optional embodiment, the first information includes a power difference group corresponding to each reference signal rotation capability of at least one reference signal rotation capability supported by the terminal device, and the power difference group includes the power differences corresponding to M diversity antennas associated with the corresponding reference signal rotation capability when the terminal device uses the corresponding reference signal rotation capability to send a reference signal.

[0020] When implementing this method, since the power difference between the diversity antenna and the main antenna may be different when the terminal device uses different reference signal rotation capabilities to send reference signals, the present application can pre-report the power difference group corresponding to each reference signal rotation capability in at least one reference signal rotation capability supported by the terminal device, thereby improving the accuracy of channel estimation and avoiding repeated reporting of power differences, saving overhead.

[0021] In an optional embodiment, the method further includes:

The power difference included in the power difference information is the power difference between the main diversity antenna and the diversity antenna when the reference signal transmission power is configured to be within the corresponding configuration power range.

[0026] When implementing this method, the power difference information corresponding to each configured power range is reported to the network device in advance. The power difference information includes a power difference group corresponding to each reference signal rotation capability in at least one reference signal rotation capability supported by the terminal device, thereby facilitating the network device to obtain the power required to compensate the diversity antenna in a scenario where the terminal device performs power compensation on the diversity antenna.

[0027] In an optional implementation, the power differences corresponding to the M diversity antennas are determined based on the limit compensation powers of the M diversity antennas, where the limit compensation power is the maximum power that can be achieved by the terminal device for power compensation of the diversity antennas.

[0028] When this method is implemented, when the terminal device can compensate for the reference signal transmission power of the diversity antenna, the maximum compensation power of the diversity antenna needs to be considered when determining the power difference corresponding to the diversity antenna, thereby improving the accuracy of determining the power difference of the diversity antenna.

[0029] In an optional embodiment, the method further includes:

[0030] Send fourth information, where the fourth information instructs the terminal device to compensate for the reference signal sending power of the M diversity antennas.

[0031] By implementing this method, the terminal device can indicate through the fourth information that the power difference group reported by the terminal device is for the scenario in which the terminal device compensates for the reference signal transmission power of the diversity antenna, thereby facilitating the network device to distinguish whether the terminal device compensates for the reference signal transmission power of the diversity antenna.

[0032] In an optional implementation, the value of Q is determined based on the maximum configured power of the reference signal transmission power and the limit compensation power threshold value of the M diversity antennas, and the limit compensation power threshold value is the minimum limit compensation power among the limit compensation powers of the M diversity antennas.

[0033] By implementing this method, the amount of power difference information that the terminal device needs to report (i.e., the value of Q) can be determined based on the maximum configuration power of the main antenna and the maximum compensation power threshold of the diversity antenna, thereby improving the accuracy of the amount of power difference information that needs to be reported, avoiding redundant reporting, and reducing signaling overhead.

[0034] In an optional embodiment, the method further includes:

[0036] By implementing this method, the terminal device can report the extreme compensation power threshold value, so that the network side can determine that compensation is only required when the configuration power of the main antenna is greater than the extreme compensation power threshold value, and no compensation is required when the configuration power of the main antenna is less than the extreme compensation power threshold value, thereby improving the efficiency of power compensation of network equipment.

[0116] Some terms involved in the embodiments of the present application are explained below to facilitate understanding by those skilled in the art.

[0117] 1. Reference signal

[0118] A reference signal (RS), also known as a pilot signal, is a known signal provided by a transmitter to a receiver for channel estimation or channel detection. Reference signals can be divided into uplink reference signals and downlink reference signals. Uplink reference signals can be used for uplink channel estimation and uplink channel quality measurement. Uplink reference signals may include: a demodulation reference signal (DMRS) and a sounding reference signal (SRS). SRS can be used by network equipment to estimate uplink channel quality and select channels, calculate the signal to interference plus noise ratio (SINR) of the uplink channel, and can also be used by network equipment to obtain uplink channel coefficients. In a time division duplexing (TDD) scenario, the uplink and downlink channels are reciprocal, and SRS can also be used by network equipment to obtain downlink channel coefficients. Network equipment can estimate uplink / downlink channel coefficients based on SRS, which can be used for uplink / downlink channel estimation.

[0119] 2. Reference signal transmission capability

[0120] The following example uses the reference signal SRS. One purpose of SRS is antenna switching. Antenna switching means that the terminal device sends SRS on multiple antennas in turn. By sending in turns, the network device can determine the channel information corresponding to multiple antennas. For TDD systems, the reciprocity of uplink and downlink channels can be used. The network device can obtain the channel state information (CSI) of the downlink channel through SRS to estimate the downlink channel. For terminal devices, the number of transmitting antennas and the number of receiving antennas can be unequal or equal, which is determined by the SRS switching capability of the terminal device.

[0121] The terminal device supports XTYR SRS transmission capability, where T refers to the transmitting antenna (transmitter) and R refers to the receiving antenna (receiver). X is less than or equal to Y, and X and Y are positive integers. Among them, X refers to the number of transmitting antennas that the terminal device can use to send SRS to the network device at the same time; Y refers to the number of antennas that the terminal device needs to use to send SRS in turn, and the Y antennas can be all or part of the antennas of the terminal device.

[0122] For example, the terminal device supports the 4T8R SRS rotation capability, which means that the terminal device can simultaneously send SRS on 4 of the 8 antennas. Through antenna rotation, the terminal device can send SRS on the other 4 antennas simultaneously next time, thereby realizing the channel information of the 8 antennas.

[0123] In different SRS round-trip transmission capabilities, the value of X is different and / or the value of Y is different. For example, the SRS round-trip transmission capability may include but is not limited to 1T2R, 1T4R, 2T4R, 4T8R, 1T8R, 2T8R, etc. For example, for SRS round-trip transmission capability 4T8R and SRS round-trip transmission capability 1T8R, the values ​​of X of the two SRS round-trip transmission capabilities are different; for SRS round-trip transmission capability 1T2R and SRS round-trip transmission capability 1T4R, the values ​​of Y of the two SRS round-trip transmission capabilities are different; for SRS round-trip transmission capability 2T4R and SRS round-trip transmission capability 1T8R, the values ​​of X and Y of the two SRS round-trip transmission capabilities are different. In the embodiment of the present application, the terminal device may support one or more SRS round-trip transmission capabilities.

[0124] The diversity antennas associated with the SRS transmission capability described in the embodiments of the present application are all the diversity antennas among the Y antennas in XTYR, usually including one main antenna and the rest are diversity antennas. Therefore, the diversity antennas associated with the SRS transmission capability are Y-1 diversity antennas.

[0125] 3. Insertion loss

[0126] Insertion loss can be understood as the power loss of a signal after passing through an electronic device, or the loss caused by PCB routing, so the smaller the insertion loss, the better.

[0127] In the embodiment of the present application, the devices passed by the main antenna are different from those passed by the diversity antenna, so the insertion loss of the main antenna is different from the insertion loss of the diversity antenna, and thus there is a power difference between the main antenna and the diversity antenna.

[0128] 4. Limit compensation power of diversity antenna

[0129] The limit compensation power of the diversity antenna is the maximum reference signal transmission power that can be achieved after the terminal device performs power compensation on the actual reference signal transmission power of the diversity antenna. For example, if the limit compensation power of the diversity antenna is 22dB, the terminal device can adjust the actual reference signal transmission power of the diversity antenna to a maximum of 22dB. It is understandable that the terminal device can also adjust the actual reference signal transmission power of the diversity antenna to be less than the limit compensation power. For example, if the actual reference signal transmission power of the diversity antenna is 15dB, and the limit compensation power of the diversity antenna is 22dB, the terminal device can also adjust the actual reference signal transmission power of the diversity antenna to 20dB. It is understandable that the reference signal transmission power after the terminal device adjusts the actual reference signal transmission power of the diversity antenna does not exceed the reference signal transmission power of the main antenna.

[0130] The limit compensation powers of different diversity antennas may be different or the same, and this application does not limit this.

[0131] Combine the following Figure 1b and Figure 1c Taking the SRS round-robin capability in the SRS architecture as an example, the SRS architecture is the maximum capability supported by the SRS round-robin capability of the terminal device. For example, if the terminal device supports the SRS round-robin capabilities of 4T8R, 1T8R and 2T8R, then the SRS architecture of the terminal device is 4T8R.

[0132] like Figure 1b As shown, it is a schematic diagram of a 4T8R SRS architecture provided by an embodiment of the present application. The SRS round-trip transmission capabilities supported by the SRS architecture include 4T8R, 1T8R and 2T8R. The main antenna is Ant1, and the others are diversity antennas (ie, Ant2-Ant8 are diversity antennas). Figure 1b It can be obtained that when the SRS round-robin transmission capacity of the SRS architecture is 1T8R, the signal of the main antenna passes through an SP8T, Ant2 and Ant3 pass through an SP8T and an SP2T, Ant4 passes through an SP8T and an SP4T. Ant5 passes through an SP8T and an SP2T, and Ant6 / 7 / 8 passes through an SP8T and an SP4T. From the analysis results, it can be seen that the devices passed by each diversity antenna are not the same, so the insertion loss of each diversity antenna is not exactly the same, so the ΔTRXSRS value defined in the protocol cannot reflect the actual power difference of the diversity antenna.

[0133] when Figure 1bWhen the SRS round-trip transmission capacity of the SRS architecture shown is 2T8R, the switches that Ant1 / Ant2 / Ant3 / Ant4 pass through remain unchanged, while Ant5 passes through one SP4T and one SP2T, Ant6 passes through two SP4Ts, Ant7 passes through two SP4Ts, and Ant8 passes through two SP4Ts. From the analysis results, we can see that under different SRS round-trip transmission capacities, even if the diversity antenna is the same, the devices it passes through are not the same, so the insertion loss of the same diversity antenna at different SRS round-trip transmission capacities is also different.

[0134] That is to say, even for the same terminal device, different diversity antennas have different insertion losses. In addition, even for the same diversity antenna, the insertion loss in different SRS round-trip transmission capabilities will be different. The actual terminal device situation is more complicated (in addition to the difference in switch components, it also includes the difference in various PCB routing losses, etc.).

[0135] The same terminal device, when supporting different frequency bands (i.e., bands), will have different insertion losses due to different device characteristics and front-end link complexity. Compared with low frequency bands, high frequency bands have greater insertion losses. For some high frequency bands, terminal devices require base station compensation due to their limited self-compensation capabilities (affected by device power). Low frequency bands may not require base station compensation because the UE can complete self-compensation.

[0136] like Figure 1c FIG. 1 is a schematic diagram of another 4T8R SRS architecture provided in an embodiment of the present application. The SRS architecture only supports 4T8R. Figure 1b The 4T8R SRS architecture shown in the figure is Figure 1c and Figure 1b The SRS transmission capabilities supported by the 4T8R SRS architecture are different. Of course, the insertion loss of the antennas involved in various SRS transmission capabilities will also be different.

[0137] In the embodiment of the present application, a terminal device generally corresponds to a certain SRS architecture connection mode. For example, the terminal device can be Figure 1b or Figure 1c The SRS architecture connection method shown.

[0138] It should be noted that the various technical solutions (or embodiments) of the present application can be implemented independently or in combination based on certain internal connections. The present application is not limited thereto. In addition, the various terms and definitions between the various embodiments can be referenced to each other. In each embodiment of the present application, different implementations can also be implemented in combination or independently.

[0139] Please refer to Figure 2a , is a flow chart of an information transmission method provided in an embodiment of the present application, such as Figure 2a As shown, the information transmission method of this embodiment includes but is not limited to the following steps:

[0140] 201. A terminal device sends first information to a network device, where the first information indicates power differences corresponding to M diversity antennas, respectively, where the power difference is a power difference between a reference signal transmission power of a corresponding diversity antenna and a reference signal transmission power of a main diversity antenna, and M is an integer greater than or equal to 1. Accordingly, the network device receives the first information.

[0141] Among them, the terminal device may include a main diversity antenna and N diversity antennas, N is an integer greater than or equal to 1, and the N diversity antennas include M diversity antennas reported by the terminal device, M is an integer less than or equal to N. In other words, the terminal device can report the power difference corresponding to all diversity antennas among the N diversity antennas, or the terminal device can report the power difference corresponding to some diversity antennas among the N diversity antennas, which is not limited in this application.

[0142] In some embodiments, the power difference corresponding to the diversity antenna may be a power difference obtained by subtracting the reference signal transmission power of the diversity antenna from the reference signal transmission power of the main antenna. Exemplarily, the reference signal includes but is not limited to SRS.

[0143] In some embodiments, when the terminal device operates in a specific frequency band, the terminal device reports the power differences corresponding to the M diversity antennas.

[0144] 202. The network device performs power compensation on the M diversity antennas according to the power differences respectively corresponding to the M diversity antennas.

[0145] After receiving the first information, the network device can determine the power differences corresponding to the M diversity antennas, and further compensate the receiving power of the corresponding diversity antenna according to the power differences of each diversity antenna. For example, if the power difference corresponding to diversity antenna 1 is 2dB, the network device receives the reference signal of diversity antenna 1 and increases the receiving power of the reference signal by 2dB.

[0146] It should be noted that the network device can also perform corresponding resource scheduling according to the power differences corresponding to the M diversity antennas, and the present application does not limit the actions performed by the network device according to the power differences.

[0147] In some embodiments, the first information may be carried in a Media Access Control Control Element (MAC CE) message, a Radio Resource Control (RRC) message, or other physical layer signaling, which is not limited in this application.

[0148] The following uses two cases as examples to illustrate how the first information indicates the power differences corresponding to the M diversity antennas:

[0149] In case 1, the first information includes power differences corresponding to M diversity antennas respectively, and the power difference corresponding to one diversity antenna among the M diversity antennas occupies P bits, where P is an integer greater than or equal to 1.

[0150] Exemplarily, each diversity antenna corresponds to P bits, and the bit values ​​of the P bits represent the power difference of the corresponding diversity antenna. For example, the value of P is 4, that is, the power difference of a diversity antenna is indicated by 4 bits, and if the bit values ​​of the P bits are 0011, it indicates that the power difference is 3dB.

[0151] For example, the power differences corresponding to the M diversity antennas may be reported in a MAC CE configuration manner. For example, P=4, that is, 4 bits are used to represent the power difference corresponding to a diversity antenna. Figure 2b As shown, it is a schematic diagram of a MACCE structure provided by the present application, and the diversity antenna power difference part of the MAC CE is used to indicate the power difference of each diversity antenna. For example, the main antenna is ant1, and the rest are diversity antennas. Each antenna (including the main antenna and the diversity antenna) corresponds to 4 bits, and the 4 bits are used to indicate the power difference of the corresponding diversity antenna. It can be understood that the 4 bits corresponding to ant1 are 0000. It should be noted that if a report only involves some of the diversity antennas among all the diversity antennas, the bits corresponding to the uninvolved diversity antennas will be retained. For example, an SRS transmission capability only involves 4 antennas ant1~ant4, and the bits corresponding to the remaining antennas ant5~ant8 will be retained.

[0152] Further optionally, the first information may also indicate which antenna is the main antenna, for example, Figure 2bAs shown, the MAC CE includes a main antenna indication part. The main antenna indication part may include 8 bits, one bit corresponds to one antenna, and if a bit is set to 1, the antenna corresponding to the bit is the main antenna. For example, if ant1 is the main antenna, the first bit of the 8 bits is set to 1, and the remaining bits are 0.

[0153] Case 2: The first information includes at least one power difference index value and the diversity antennas corresponding to the at least one power difference index value. One power difference index value in the at least one power difference index value may indicate a power difference.

[0154] In some embodiments, the power difference can be reported through a power difference index value, one power difference index value corresponds to one power difference, and the correspondence between the power difference index value and the power difference can be specified by the protocol, or can also be pre-configured by the network device, for example, the network device can be configured through an RRC message. As shown in Table 1, it is a table of the correspondence between the power difference and the power difference index value. For example, the power difference index value 01 indicates a power difference of 1dB, the power difference index value 02 indicates a power difference of 3dB, and so on. The network device can determine the corresponding power difference through the power difference index value. In other words, the power difference indicated by the power difference index value is the power that the network device needs to compensate.

[0155] Exemplarily, a power difference index value may correspond to one or more diversity antennas, and the power difference of the one or more diversity antennas is the power difference indicated by the power index value. To facilitate the network device to determine the one or more diversity antennas corresponding to the power difference index value, the first information also needs to indicate the one or more diversity antennas corresponding to the power difference index value. For example, if the first information indicates that the diversity antennas corresponding to the power difference index value 02 are ant1 and ant2, it means that the power difference corresponding to the diversity antennas ant1 and ant2 is 3dB, and the network device needs to compensate the diversity antennas ant1 and ant2 by 3dB respectively.

[0156]

[0157]

[0158] Table 1

[0159] The power difference indicated by the above power difference index value is the power that the network device needs to compensate. In some implementation manners, the actual power difference between the reference signal transmission power of the diversity antenna and the reference signal transmission power of the main antenna may be different from the power difference indicated by the power difference index value. For example, if the actual power difference between the reference signal transmission power of diversity antenna 1 and the reference signal transmission power of the main antenna is x dB, and if 1 < x ≤ 2 dB, it is determined that the power difference that the network device needs to compensate is 2 dB. Therefore, the power difference index value corresponding to diversity antenna 1 included in the first information is 02.

[0160] As shown in Table 2, it is an example of the correspondence relationship between the actual power difference x between the reference signal transmission power of the diversity antenna and the reference signal transmission power of the main antenna, the power difference index value, and the power difference indicated by the power difference index value. The power difference indicated by the power difference index value is the power difference that the network device needs to compensate. In other words, if the actual power difference x is within a range, when reporting, the power difference index value is reported, and the network device can compensate according to a power difference indicated by the power difference index value. It can be understood that each actual power difference range in Table 2 is only for example, and the size of each actual power difference range may not be limited. For example, it can also be that 0 dB < x ≤ 4 dB corresponds to a power difference index value.

[0161]

[0162] Table 2

[0163] The above Case 1 and Case 2 are two examples of the first information indicating the power difference, and there can be other indication manners, which are not limited in this application.

[0164] In the embodiments of this application, the terminal device can indicate the power differences corresponding to M diversity antennas respectively through the first information. In other words, the terminal device reports the actual power differences corresponding to M diversity antennas respectively, so that the network device can compensate each diversity antenna according to the actual power difference, and try to balance the power of the main antenna and the diversity antenna to improve the accuracy of channel estimation.

[0165] Please refer to Figure 3 , which is a schematic flowchart of another information transmission method provided by the embodiments of this application. As Figure 3 shown, the information transmission method of this embodiment includes but is not limited to the following steps:

[0166] 301, the terminal device measures the reference signal transmission powers corresponding to M diversity antennas respectively and the reference signal transmission power corresponding to the main antenna.

[0167] The terminal device can measure in real time the reference signal transmission power corresponding to the M diversity antennas and the reference signal transmission power corresponding to the main diversity antenna. The M diversity antennas may be the M diversity antennas associated with the reference signal rotation capability currently used by the terminal device. For example, if the reference signal rotation capability currently used by the terminal device is 4T8R, the M diversity antennas associated with the reference signal rotation capability currently used are all the diversity antennas in the 8 antennas, that is, 7 diversity antennas (one of which is a main diversity antenna).

[0168] 302. The terminal device determines the power differences corresponding to the M diversity antennas respectively according to the reference signal transmit powers corresponding to the M diversity antennas respectively and the reference signal transmit powers corresponding to the main diversity antenna.

[0169] The terminal device calculates the power difference between the reference signal transmission power of each diversity antenna and the reference signal transmission power of the main diversity antenna, thereby obtaining the power difference corresponding to each diversity antenna.

[0170] 303. The terminal device sends first information to the network device, where the first information indicates power differences corresponding to the M diversity antennas.

[0171] In some embodiments, the terminal device reports the measured power difference of each diversity antenna to the network device. Exemplarily, if the SRS transmission is periodic, the terminal device reports the power difference periodically. Exemplarily, if the SRS transmission is non-periodic, the terminal device also reports the power difference non-periodically. Exemplarily, if the SRS transmission is semi-continuous, the terminal device also reports the power difference semi-continuously.

[0172] For example, the terminal device may periodically report the first information, that is, the terminal device periodically reports the power differences corresponding to the M diversity antennas. The period for the terminal device to report the first information may be the same as the SRS transmission period. The first information may include the power differences corresponding to the M diversity antennas, or include at least one power difference index value. For details, refer to Figure 2a The description of step 201 of the embodiment will not be repeated here. It should be noted that when the reference signal transmission capability of the terminal device changes, the value of M may change.

[0173] In this embodiment, the terminal device measures the reference signal transmission power of M diversity antennas and the reference signal transmission power of the main antenna in real time, and calculates the power difference. The method of periodically reporting the obtained power difference can be understood as a dynamic reporting of the power difference.

[0174] In some embodiments, the terminal device may also send second information indicating the reference signal transmission power of the M diversity antennas and the reference signal transmission power of the main antenna, so that the network device can determine the transmission power of the main antenna and the diversity antenna.

[0175] 304. The network device performs power compensation on the M diversity antennas according to the power differences corresponding to the M diversity antennas.

[0176] Please refer to step 304 of this application embodiment. Figure 2a The description of step 202 in the embodiment will not be repeated here.

[0177] In an embodiment of the present application, the terminal device can measure the reference signal transmission power of the diversity antenna and the reference signal transmission power of the main antenna in real time, and report the power difference, which can improve the accuracy of the reported power difference.

[0178] Please refer to Figure 4 , is a flow chart of another information transmission method provided in an embodiment of the present application, wherein step 402 is an optional step, such as Figure 4 As shown, the information transmission method of this embodiment includes but is not limited to the following steps:

[0179] 401, the terminal device sends first information to the network device, the first information including a power difference group corresponding to each reference signal transmission capability in at least one reference signal transmission capability supported by the terminal device. The power difference group includes power differences corresponding to M diversity antennas associated with the corresponding reference signal transmission capability. Accordingly, the network device receives the first information.

[0180] The SRS architecture of the terminal device may support one or more reference signal transmission capabilities. For example, if the SRS architecture of the terminal device is Figure 1b According to the architecture shown, the terminal device can support three reference signal transmission capabilities, which are 4T8R, 1T8R, and 2T8R. The M diversity antennas associated with the three reference signal transmission capabilities are all Ant1 to Ant8. In some implementations, the M diversity antennas associated with different reference signal transmission capabilities may be different. For example, the SRS architecture of the terminal device is 1T4R, and the two reference signal transmission capabilities supported by the terminal device are 1T2R and 1T4R, respectively. Then, the M diversity antennas associated with the reference signal transmission capability 1T2R are all diversity antennas in the 2R antennas, that is, 1 diversity antenna, and the M diversity antennas associated with the reference signal transmission capability 1T4R are all diversity antennas in the 4R antennas, that is, 3 diversity antennas.

[0181] The first information may include a power difference group corresponding to each reference signal transmission capability in at least one reference signal transmission capability supported by the terminal device. One reference signal transmission capability may correspond to one power difference group. For example, reference signal transmission capability 1T2R corresponds to one power difference group, and reference signal transmission capability 1T4R corresponds to one power difference group. The power difference group corresponding to one reference signal transmission capability includes the power differences corresponding to the M diversity antennas associated with the reference signal transmission capability. For example, the power difference group corresponding to the reference signal transmission capability 1T2R includes the power difference corresponding to one diversity antenna, and the power difference group corresponding to the reference signal transmission capability 1T4R includes the power differences corresponding to three diversity antennas.

[0182] 402, the terminal device sends third information to the network device, the third information indicating that the terminal device has not compensated the reference signal transmission power of the diversity antenna. Correspondingly, the network device receives the third information.

[0183] The fact that the terminal device does not compensate for the reference signal transmission power of the diversity antenna can be understood as the fact that the terminal device does not adjust the reference signal transmission power, that is, the power difference corresponding to the diversity antenna is calculated based on the actual reference signal transmission power of the diversity antenna, that is, the reference signal transmission power of the main antenna minus the actual reference signal transmission power of the diversity antenna to obtain the power difference corresponding to the diversity antenna. The actual reference signal transmission power of the diversity antenna can be understood as the reference signal transmission power of the diversity antenna when the terminal device does not adjust the reference signal transmission power of the diversity antenna.

[0184] The third information indicates that the power difference carried in the first information is the power difference when the terminal device does not compensate for the reference signal transmission power of each diversity antenna.

[0185] 403 , the network device performs power compensation on the M diversity antennas according to the power differences corresponding to the M diversity antennas.

[0186] The network device may determine the power difference group corresponding to each reference signal transmission capability in at least one reference signal transmission capability supported by the terminal device according to the first information. When the terminal device sends a reference signal to the network device, the network device needs to first determine the reference signal transmission capability currently used by the terminal device, and further obtain the power difference group corresponding to the reference signal transmission capability currently used by the terminal device from the first information, wherein the power difference group includes the power differences corresponding to the M diversity antennas associated with the reference signal transmission capability currently used by the terminal device, so as to perform power compensation on the M diversity antennas according to the power differences corresponding to the M diversity antennas.

[0187] In an embodiment of the present application, since the power difference between the diversity antenna and the main antenna may be different when the terminal device uses different reference signal rotation capabilities to send a reference signal, the present application can pre-report the power difference group corresponding to each reference signal rotation capability in at least one reference signal rotation capability supported by the terminal device, so that when the subsequent network device and the terminal device transmit the reference signal, they can find the corresponding power difference group according to the reference signal rotation capability currently used by the terminal device, thereby realizing power compensation for the diversity antenna, and avoiding repeated reporting of the power difference while improving the accuracy of the channel estimation, saving overhead.

[0188] The following is an example of the power difference reporting method in combination with Table 3 and Table 4. In the following example, the reference signal is SRS as an example:

[0189] As shown in Table 2, a schematic diagram of the SRS architecture and SRS round-robin capability support provided in an embodiment of the present application is provided. The main antenna is Ant1. For the same SRS architecture, one or more SRS round-robin capabilities can be supported. As shown in Table 2, the SRS round-robin capability supported by the SRS architecture 1T2R is 1T2R, and the SRS round-robin capability supported by the SRS architecture 1T4R can be 1T2R and 1T4R.

[0190] Before reporting the power difference, the SRS architecture of the terminal device is determined, and the SRS architecture of the terminal device is usually a certain architecture. Further, according to the correspondence between the SRS architecture and the supported SRS round-trip capability in the table shown in Table 3, at least one SRS round-trip capability supported by the SRS architecture of the terminal device is searched.

[0191]

[0192]

[0193] Table 3

[0194] As shown in Table 4, a schematic diagram of the correspondence between the SRS transmission capability and the power difference group provided in the embodiment of the present application is provided. The main antenna is Ant1. After determining at least one SRS transmission capability supported by the terminal device, the power difference group corresponding to each SRS transmission capability is determined. A power difference group includes one or more power differences. As shown in Table 4, the power difference group corresponding to the SRS transmission capability 1T2R includes ΔX11, and ΔX11 is the reference signal transmission power difference between the diversity antenna Ant2 and the main antenna Ant1. The power difference group corresponding to the SRS transmission capability 1T4R includes ΔX21, ΔX31, and ΔX41.

[0195]

[0196] Table 4

[0197] Next, we will continue to explain the power difference reporting for the SRS architecture of the terminal device of 4T8R by combining Table 5 and Table 6. As shown in Table 5, the SRS architecture of the terminal device is 4T8R, and the SRS round-trip transmission capabilities supported by the SRS architecture are 1T2R, 1T4R, 2T4R, 1T8R, 2T8R and 4T8R.

[0198]

[0199] Table 5

[0200] The power difference corresponding to the diversity antenna associated with each SRS transmission capability is further determined, as shown in Table 6, which is a schematic diagram of the power difference corresponding to one or more diversity antennas associated with various SRS transmission capabilities. The power difference corresponding to one or more diversity antennas associated with one SRS transmission capability can form a power difference group, in which the main diversity antenna is Ant1.

[0201] To save overhead, if the power differences of multiple diversity antennas are the same, they may be reported once, that is, one power difference is reported, and multiple diversity antennas corresponding to the power difference are indicated.

[0202] Optionally, the value filled with 0 in Table 5 may not be reported, and the default power difference value not reported is 0. Optionally, the empty value in Table 6 is not reported either. For example, for the SRS round-robin capability 1T2R, since the diversity antenna associated with the SRS round-robin capability is Ant2, the power differences corresponding to the remaining diversity antennas are empty.

[0203]

[0204] Table 6

[0205] In this embodiment of the present application, the pre-reporting of the power difference group corresponding to the various reference signal transmission capabilities can be understood as a static reporting method. The static reporting method is that the terminal device reports a fixed power difference, and after one report, no real-time update is required.

[0206] Please refer to Figure 5 , is a flow chart of another information transmission method provided in an embodiment of the present application, wherein step 502 and step 503 are optional steps, such as Figure 5 As shown, the information transmission method of this embodiment includes but is not limited to the following steps:

[0207] 501. The terminal device sends first information to the network device. The first information includes Q power difference information. One power difference information among the Q power difference information corresponds to a configured power range. Q is an integer greater than or equal to 1.

[0208] The first information includes Q power difference information corresponding to the Q configured power ranges, one configured power range corresponds to one power difference information, that is, the Q configured power ranges correspond to the Q power difference information one by one. For example, Q=2, the configured power range 1 corresponds to the power difference information 1, and the configured power range 2 corresponds to the power difference information 2. The existence form of the power difference information is not limited, for example, one power difference information can be all the power differences in a table.

[0209] The configured power range is the reference signal transmission power range configured by the network device, and is not limited to the reference signal transmission power range configured by the network device as a main antenna or a diversity antenna. Since the insertion loss of the main antenna is relatively small, the reference signal transmission power of the main antenna is the same as or close to the reference signal transmission power configured by the network device. For ease of description, this application takes the reference signal transmission power of the main antenna as equal to the reference signal transmission power configured by the network device as an example.

[0210] For example, if the reference signal transmission power configured by the network device is in the configured power range 1, then the corresponding power difference information 1, that is, all power differences in the power difference information 1 are calculated based on the reference signal transmission power of the main set antenna within the configured power range 1. For another example, if the reference signal transmission power configured by the network device is in the configured power range 2, then the corresponding power difference information 2, that is, all power differences in the power difference information 2 are calculated based on the reference signal transmission power of the main set antenna within the configured power range 2. For the specific calculation method, please refer to the description of the subsequent embodiments. The reference signal transmission power configured by the network device for the main set antenna can be changed. The present application pre-sends the power difference information corresponding to Q different configured power ranges to the network device.

[0211] It can be seen from the above description that a configured power range corresponds to a power difference information. Further, a power difference information may include a power difference group corresponding to each reference signal transmission capability in at least one reference signal transmission capability. A power difference group includes power differences corresponding to M diversity antennas associated with the corresponding reference signal transmission capability. For example, taking the above power difference information 1 as an example, the terminal device supports two reference signal transmission capabilities, namely 1T2R and 1T4R. The power difference information 1 may include power difference groups corresponding to the two reference signal transmission capabilities 1T2R and 1T4R. The power difference group corresponding to the reference signal transmission capability 1T2R includes the power difference corresponding to 1 diversity antenna, and the power difference group corresponding to the reference signal transmission capability 1T4R includes the power difference corresponding to 3 diversity antennas. All power differences contained in the power difference information 1 are calculated based on the reference signal transmission power of the main antenna when it is configured in the configured power range 1.

[0212] Among them, there is no overlap between the Q configured power ranges corresponding to the Q power difference information. The absence of overlap in the configured power ranges can be understood as no one configured power belonging to multiple configured power ranges. For example, the value of Q is 3, the first configured power range is greater than 0dB and less than or equal to 1dB, the second configured power range is greater than 1dB and less than or equal to 2dB, and the third configured power range is greater than 2dB and less than or equal to 3dB. There is no overlap between the three configured power ranges.

[0213] Alternatively, the Q configured power ranges may also be Q configured power values, one configured power value corresponds to one power difference information, the power difference information is the power difference information when the reference signal transmission power of the main antenna is configured as the corresponding configured power value, and similarly, the power difference information includes a power difference group corresponding to each reference signal transmission capability in at least one reference signal transmission capability. The power difference group includes the power differences corresponding to the M diversity antennas associated with the corresponding reference signal transmission capability.

[0214] In some embodiments, the Q configured power ranges or the values ​​of the Q configured powers may be determined based on the maximum configured power of the main antenna and the limit compensation power thresholds of the M diversity antennas, and the limit compensation power threshold may be the minimum limit compensation power among the limit compensation powers corresponding to the M diversity antennas. For example, if M is 3, the limit compensation power of diversity antenna 1 is 22 dB, the limit compensation power of diversity antenna 2 is 23 dB, and the limit compensation power of diversity antenna 3 is 24 dB, then the limit compensation power threshold is the minimum limit compensation power of 22 dB among diversity antenna 1, diversity antenna 2, and diversity antenna 3.

[0215] In one implementation, the power range between the maximum configuration power of the main antenna and the limit compensation power threshold is divided into Q non-overlapping configuration power ranges. The range sizes of different configuration power ranges may be the same or different, and this application does not limit this. The following takes the same range size of each configuration power range as an example. For example, the maximum configuration power of the main antenna is 25dB, and the limit compensation power threshold is 22dB. Then, 22dB to 25dB can be divided into 3 configuration power ranges, range 1 is greater than 22dB and less than or equal to 23dB, range 2 is greater than 23dB and less than or equal to 24dB, and range 3 is greater than 24dB and less than or equal to 25dB.

[0216] 502, the terminal device sends fourth information to the network device, the fourth information instructing the terminal device to compensate the reference signal transmission power of the diversity antenna. Correspondingly, the network device receives the fourth information.

[0217] In order to facilitate the network device to know whether the power difference in the above-mentioned first information is the power difference in the scenario where the terminal device performs self-power compensation, the terminal device can indicate to the network device through the fourth information that the terminal device has compensated the reference signal sending power of the diversity antenna.

[0218] 503, the terminal device sends fifth information to the network device, where the fifth information indicates a limit compensation power threshold value. Correspondingly, the network device receives the fifth information.

[0219] When the configured power of the main antenna is less than or equal to the extreme compensation power threshold value, it means that all diversity antennas can achieve a balance between the reference signal sending power of the main antenna and the reference signal sending power of the diversity antenna through self-power compensation, and the network device does not need to perform power compensation. When the configured power of the main antenna is greater than the extreme compensation power threshold value, there may be some diversity antennas that cannot achieve a balance between the reference signal sending power with the main antenna through self-power compensation, and therefore the network device needs to perform power compensation. Therefore, the present application indicates the antennas that require power compensation by the network device and the power value that needs to be compensated through the above-mentioned first information.

[0220] The terminal device can indicate the limit compensation power threshold value to the network device through the fifth information, so that the network device determines that the configuration power of the main antenna is less than or equal to the limit compensation power threshold value and does not need to perform power compensation on any diversity antenna. When the network device determines that the configuration power of the main antenna is greater than the limit compensation power threshold value, it is necessary to determine the power value that needs to be compensated through the first information.

[0221] 504 , the network device performs power compensation on the M diversity antennas according to the power differences respectively corresponding to the M diversity antennas.

[0222] When the network device performs power compensation on the diversity antenna, it must first determine the configuration power range of the configuration power of the main antenna and find the corresponding power difference information. The network device also needs to determine the reference signal transmission capability currently used by the terminal device, and then determine the power differences corresponding to the M diversity antennas associated with the currently used reference signal transmission capability from the power difference information found, and perform power compensation on the M diversity antennas according to the power differences corresponding to the M diversity antennas.

[0223] In an embodiment of the present application, power difference information corresponding to each configured power range is reported to the network device in advance, and the power difference information includes a power difference group corresponding to each reference signal rotation capability in at least one reference signal rotation capability supported by the terminal device, thereby facilitating the network device to obtain the power required to compensate the diversity antenna in a scenario where the terminal device performs power compensation on the diversity antenna.

[0224] The following takes the limit compensation power threshold value of XdB and the maximum configuration power of YdB as an example, Ant1 is the main antenna, and the size of a configuration power range is 1dB as an example. In the following description, the configuration power of the reference signal transmission power of the network device is equal to the reference signal transmission power of the main antenna as an example.

[0225] As shown in Table 7, the power difference information corresponding to the configuration power range 1 is a table as an example. The configuration power range 1 is greater than XdB and less than or equal to X+1dB, that is, when the configuration power of the main antenna belongs to the configuration power in the configuration power range 1, the network device performs power compensation on the corresponding diversity antenna according to the power difference in Table 7. As shown in Table 7, when the terminal device uses the reference signal transmission capability 1T2R, the power difference group corresponding to the reference signal transmission capability 1T2R includes ΔX11. When the terminal device uses the reference signal transmission capability 1T4R, the power difference group corresponding to the reference signal transmission capability 1T4R includes ΔX21, ΔX31, and ΔX41.

[0227]

[0228] Table 7

[0229] As shown in Table 8, the power difference information corresponding to the configuration power range 2 is greater than X+1dB and less than or equal to X+2dB, that is, when the configuration power of the main antenna belongs to the configuration power in the configuration power range 2, the network device performs power compensation on the corresponding diversity antenna according to the power difference in Table 8. As shown in Table 8, when the terminal device uses the reference signal transmission capability 1T2R, the power difference group corresponding to the reference signal transmission capability 1T2R includes ΔX12. When the terminal device uses the reference signal transmission capability 1T4R, the power difference group corresponding to the reference signal transmission capability 1T4R includes ΔX22, ΔX32, and ΔX42.

[0230]

[0231] Table 8

[0232] As shown in Table 9, the power difference information corresponding to the configuration power range 3 is greater than X+2dB and less than or equal to X+3dB, that is, when the configuration power of the main antenna belongs to the configuration power in the configuration power range 3, the network device performs power compensation on the corresponding diversity antenna according to the power difference in Table 9. As shown in Table 9, when the terminal device uses the reference signal transmission capability 1T2R, the power difference group corresponding to the reference signal transmission capability 1T2R includes ΔX13. When the terminal device uses the reference signal transmission capability 1T4R, the power difference group corresponding to the reference signal transmission capability 1T4R includes ΔX23, ΔX33, and ΔX43.

[0233]

[0234] Table 9

[0235] By analogy, the next configured power range 3 is greater than X+3dB and less than or equal to X+4dB, until the last configured power range is greater than Y-1dB and less than or equal to YdB.

[0236] In this embodiment, the power difference in the power difference information corresponding to each configured power range is the power difference in the scenario where each diversity antenna performs self-compensation. In other words, when calculating the power difference corresponding to each diversity antenna, the limit compensation power of the diversity antenna is taken into account. The following is an example of the calculation of the diversity antenna Ant2 in Table 7 and Table 8 in different configured power ranges when the round-trip transmission capacity is 1T2R, and other diversity antennas can be analogized. For example, the limit compensation power threshold is 22dB, and the limit compensation power of the diversity antenna Ant2 is 24dB. Case 1, when the configured power of the main antenna Ant1 is greater than 22dB and less than or equal to 23dB, the calculation is based on the configured power of the main antenna Ant1 being 23dB. Since the configured power of the main antenna Ant1 is less than the limit compensation power of the diversity antenna Ant2 of 24dB, the diversity antenna Ant2 can self-compensate to balance the configured power of the main antenna, so no network device compensation is required, ΔX11=0dB. Case 2: When the configured power of the main antenna Ant1 is greater than 23dB and less than or equal to 24dB, the calculation is based on the configured power of the main antenna Ant1 being 24dB. Since the configured power of the main antenna Ant1 is equal to the maximum compensation power of the diversity antenna Ant2, 24dB, no network equipment compensation is required, and ΔX12 = 0dB. Case 3: When the configured power of the main antenna Ant1 is greater than 24dB and less than or equal to 25dB, the calculation is based on the configured power of the main antenna Ant1 being 25dB. Since the configured power of the main antenna Ant1 is greater than the maximum compensation power of the diversity antenna Ant2, 24dB, the network equipment needs to compensate by 1dB, and ΔX13 = 1dB. When the configured power of the main antenna Ant1 is further increased, the power that the network equipment needs to supplement is the value obtained by subtracting the maximum compensation power of the diversity antenna Ant2, 24dB, from the configured power of the main antenna Ant1.

[0237] When the configured power of the main antenna is less than or equal to the limit compensation power of the diversity antenna, the network device does not need to perform power compensation on the diversity antenna, that is, the power difference corresponding to the diversity antenna is 0dB. When the configured power of the main antenna is greater than the limit supplement power of the diversity antenna, the network device needs to perform power compensation on the diversity antenna by subtracting the limit compensation power of the diversity antenna from the configured power of the main antenna.

[0238] For example, continuing with Table 7, Table 8, and Table 9 as examples, if the configuration power of the main antenna is X+1dB, the corresponding power difference information is in Table 7. If the reference signal transmission capability currently used by the terminal device is 1T2R, then the M diversity antennas associated with the reference signal transmission capability 1T2R are Ant2, and the network device performs power compensation on the diversity antenna Ant2 according to ΔX12.
