[0055] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0056] The Sounding Reference Signal (SRS) is an uplink reference signal transmitted by a terminal device to a base station. The signal is mainly used by the base station to measure the uplink channel quality.

[0057] Figure 2 is a schematic diagram of an SRS transmission. As shown in Figure 2, a terminal device corresponds to a PA in a certain frequency band. The SRS signal transmitted by the PA is radiated to the spatial channel through the terminal device's antenna 1 and is received by the base station. The base station can determine the channel conditions from the terminal device's antenna 1 to the base station by measuring the SRS signal. For the time division duplex (TDD) frequency band, since the uplink and downlink are at the same operating frequency, the uplink channel and the downlink channel can usually be considered to be the same (or reciprocal). By measuring the uplink SRS, the base station also determines the downlink channel conditions from the base station to the UE antenna 1.

[0058] For a UE with t1r4 (one transmit antenna and four receive antennas) as shown in Figure 2, the base station can measure the downlink channel condition (also known as downlink channel quality) from the base station to antenna 1 by measuring the SRS signal transmitted by antenna 1. However, the downlink channel condition from the base station to antennas 2 / 3 / 4 cannot be determined due to the lack of SRS signals.

[0059] Optionally, the channel condition in any embodiment of the present application may be understood as the same as the channel quality.

[0060] Figure 3 is a schematic diagram of a base station transmitting information. As shown in Figure 3, because the base station can measure the downlink channel conditions from the base station to antenna 1 based on the SRS signal transmitted by measurement antenna 1, it can send information to antenna 1 so that the low noise amplifier (LNA) can receive the information. However, because the base station cannot obtain the downlink channel conditions from the base station to antennas 2, 3, and 4, it is difficult for the base station to accurately configure the codebook for the UE when performing downlink MIMO scheduling, resulting in overall performance degradation (for example, degradation of terminal device reception performance).

[0061] Figure 4 shows another SRS transmission scheme. To overcome the problem of a base station being unable to obtain channel conditions for receive antennas other than the primary antenna when a terminal device has fewer transmit links than receive links, an SRS antenna switching mechanism is introduced. The PA transmits alternately on antennas 1, 2, 3, and 4 to ensure SRS coverage for all receive antennas. After receiving all SRSs, the base station can obtain channel quality information from the base station to the UE's receive antennas 1, 2, 3, and 4.

[0062] Optionally, SRS antenna rotation can be related to a specific frequency band and the number of transmit antennas and / or receive antennas supported by the terminal device in that frequency band. For example, a terminal device that supports one transmit antenna and four receive antennas can report a capability of, for example, t1r4 SRS antenna rotation. For example, a terminal device that supports one transmit antenna and two receive antennas can report a capability of, for example, 1t2r SRS antenna rotation. The base station will configure SRS antenna switch time-frequency resources based on the SRS antenna switch capability of the terminal device, based on the frequency band. For example, if the terminal device reports t1r4 capability, the base station will correspondingly configure four SRS time-frequency resources for the terminal device to complete the SRS rotation on the four receive antennas, or the base station will correspondingly configure two SRS time-frequency resources for the terminal device to complete the SRS rotation on the two receive antennas.

[0063] FIG5 is a flow chart of a method for transmitting an SRS by a terminal device. As shown in FIG5 , the method includes:

[0064] S501: The terminal device reports the SRS antenna rotation transmission capability.

[0065] For example, the SRS antenna transmission round capability may include t1r4, t1r2, t2r2, t2r2, etc.

[0066] S502: The network device configures SRS antenna rotation transmission resources (set).

[0067] Optionally, the SRS antenna rotation transmission resource (set) may be an SRS antenna rotation transmission resource or an SRS antenna rotation transmission resource set.

[0068] Optionally, the SRS antenna rotation transmission resource (set) may correspond to the SRS antenna rotation transmission capability.

[0069] S503: The terminal device transmits SRS on the corresponding SRS antenna rotation transmission resources.

[0070] Therefore, in order to enable the base station to obtain downlink channel quality information from the receive-only antenna, a rotation mechanism between SRS antennas is introduced. However, a potential problem is the impact of different antenna positions of terminal devices on channel quality determination.

[0071] Figure 6 shows the location of the PA and antennas in a terminal device. As shown in Figure 6, antennas 1 through 4 are located in different locations within the terminal device, with the PA typically located in the upper half. This results in different distances and losses from the PA to different antennas. While the PA transmits the same power, the actual power reaching different antennas is different. This creates a problem: the difference in transmit power between antennas is invisible to the base station. The base station interprets the difference in loss between antennas as a difference in propagation loss in the spatial channel, causing errors in the base station's downlink channel estimation, which fails to fully match the actual downlink channel conditions.

[0072] This application will consider how to improve the accuracy of SRS antenna rotation for channel estimation from the perspective of channel estimation errors caused by differences in actual antenna layouts of terminal devices.

[0073] 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 above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0074] Different antenna positions of terminal devices may result in different insertion losses (IL), causing errors when the base station estimates the downlink channel quality by measuring the SRS signal strength. In the embodiments of the present application, this problem is solved by the terminal device reporting the corresponding IL when the SRS is transmitted on different antennas to the base station. The base station can then correct the measured SRS signal strength to obtain accurate channel quality.

[0075] FIG7 is a flow chart of a communication method provided in an embodiment of the present application. As shown in FIG7 , the method includes:

[0076] S701. A terminal device sends at least one first insertion loss value; and a network device receives at least one first insertion loss value.

For example, the distances between two antennas and the PA are different, and the two first insertion loss values ​​corresponding to the two antennas are different. For another example, the propagation losses between two antennas and the PA are different, and the two first insertion loss values ​​corresponding to the two antennas are different. For another example, when the transmit power corresponding to the PA is the first transmit power, the first insertion loss value corresponding to a certain antenna is A, and when the transmit power corresponding to the PA is the second transmit power, the first insertion loss value corresponding to the antenna is B, wherein the first transmit power and the second transmit power are different, and A and B may be the same or different. For another example, when the frequency band corresponding to uplink reference signal transmission is the first frequency band, the first insertion loss value corresponding to a certain antenna is C. When the frequency band corresponding to uplink reference signal transmission is the second frequency band, the first insertion loss value corresponding to the antenna is D. The first and second frequency bands are different, and C and D can be the same or different. For another example, if two antennas have different models but the same distance from the PA and the same propagation loss with the PA, the two first insertion loss values ​​corresponding to the two antennas can be the same or different.

[0085] Optionally, the at least one antenna may be all antennas used to send uplink reference signals, or some of all antennas used to send uplink reference signals. For example, if all antennas used to send uplink reference signals may be antennas 1-4, then the at least one antenna may be antennas 1-4, or the at least one antenna may be any three of antennas 1-4.

[0086] Optionally, each first insertion loss value may be an insertion loss value corresponding to when the uplink reference signal is transmitted through each antenna of the at least one antenna. Optionally, when the antennas used to transmit the uplink reference signal include antennas 1 to 4, the terminal device transmits four first insertion loss values, and the four first insertion loss values ​​may be insertion loss values ​​corresponding to when the uplink reference signal is transmitted through antennas 1 to 4, respectively.

[0088] In this embodiment of the present application, a terminal device transmits at least one first insertion loss value; the at least one first insertion loss value corresponds one-to-one with at least one antenna used to transmit an uplink reference signal. Thus, the terminal device reports the at least one first insertion loss value corresponding one-to-one with the at least one antenna, allowing the network device to determine the uplink channel quality and / or downlink channel quality based on the at least one first insertion loss value, thereby improving the accuracy of the estimated uplink channel quality and / or downlink channel quality.

[0089] Optionally, in some other embodiments, a terminal device may transmit at least one first insertion loss value to another terminal device; the at least one first insertion loss value corresponds one-to-one with at least one antenna used to transmit a sidelink reference signal.

[0091] Optionally, each first insertion loss value may be an insertion loss value corresponding to the uplink reference signal when it is transmitted through each antenna of at least one antenna in the current frequency band. Optionally, the corresponding insertion loss values ​​may be different for different antennas. Optionally, in the case where the antennas used to send the uplink reference signal include antennas 1 to 4, the terminal device sends 4 first insertion loss values / 3 first insertion loss values, the 4 first insertion loss values ​​may be the insertion loss values ​​corresponding to the uplink reference signal when it is transmitted through antennas 1 to 4 in the current frequency band, and the 3 first insertion loss values ​​may be the relative values ​​of insertion losses corresponding to the uplink reference signal when it is transmitted through any three antennas of antennas 1 to 4 in the current frequency band.

[0101] In some embodiments, the at least one first insertion loss value includes at least one absolute insertion loss value. Thus, each first insertion loss value is an absolute insertion loss value. For example, if there are four antennas used to transmit an uplink reference signal, the terminal device transmits four absolute insertion loss values, each corresponding to one of the four antennas.

[0102] In some embodiments, the at least one first insertion loss value includes at least one relative insertion loss value. Thus, each first insertion loss value is a relative insertion loss value. The target antenna is used to transmit the uplink reference signal, and each relative insertion loss value is determined based on the difference between each absolute insertion loss value and the absolute insertion loss value corresponding to the target antenna.

[0103] For example, when there are four antennas used to send uplink reference signals, the terminal device may send three relative insertion loss values, wherein the three relative insertion loss values ​​correspond one-to-one to three of the four antennas, and the three antennas are antennas other than the target antenna among the four antennas. For another example, when there are four antennas used to send uplink reference signals, the terminal device may send four relative insertion loss values, wherein the four relative insertion loss values ​​correspond one-to-one to the four antennas, and the relative insertion loss value corresponding to the target antenna among the four antennas may be 0. For another example, in other embodiments, when there are four antennas used to send uplink reference signals, the four relative insertion loss values ​​may be the relative insertion loss values ​​corresponding to the four antennas relative to a specific antenna, and the specific antenna may be an antenna other than the four antennas.

[0110] Optionally, at least one interval indication / index of the absolute value of insertion loss corresponds one-to-one to at least one antenna used to send an uplink reference signal.

[0111] Optionally, if the intervals corresponding to different absolute values ​​of insertion loss are the same, the interval indications / indexes of the different absolute values ​​of insertion loss are the same. Optionally, if the intervals corresponding to different absolute values ​​of insertion loss are different, the interval indications / indexes of the different absolute values ​​of insertion loss are different. For example, the multiple intervals include: interval 1 is 0≤IL<2dB, interval 2 is 2≤IL<4dB, interval 3 is 4≤IL<6, interval 4 is 6≤IL<8 or 6≤IL. If at least one absolute value of insertion loss is 1.5dB, 1.8dB, or 2.5dB, respectively, the interval indication / index of at least one absolute value of insertion loss is 1, 1, or 2, respectively.

[0112] In some embodiments, the at least one first insertion loss value includes an interval indication / index of at least one relative insertion loss value. The target antenna is used to transmit the uplink reference signal, and each relative insertion loss value is determined based on a difference between each absolute insertion loss value and an absolute insertion loss value corresponding to the target antenna.

[0113] Optionally, at least one interval indication / index of the relative insertion loss value corresponds one-to-one with at least one antenna used to transmit an uplink reference signal. Optionally, at least one interval indication / index of the relative insertion loss value corresponds one-to-one with an antenna other than the target antenna in the at least one antenna used to transmit an uplink reference signal.

[0114] Optionally, if different relative insertion loss values ​​correspond to the same interval, the interval indications / indexes of the different relative insertion loss values ​​are the same. Optionally, if different relative insertion loss values ​​correspond to different intervals, the interval indications / indexes of the different relative insertion loss values ​​are different. For example, the multiple intervals include: interval 1 is 0≤IL<1dB, interval 2 is 1≤IL<2dB, interval 3 is 2≤IL<3, interval 4 is 3≤IL<4 or 4≤IL. If at least one relative insertion loss value is 0.2dB, 0.5dB, or 1.5dB, respectively, the interval indication / index of at least one relative insertion loss value is 1, 1, or 2, respectively.

[0115] Optionally, the interval of at least one absolute value of insertion loss may be the same as, different from, or partially the same as, the interval of at least one relative value of insertion loss.

[0191] The following describes the communication method in the embodiment of the present application by taking the uplink reference signal as SRS and the network device as a base station as an example:

[0192] Figure 8 is a schematic diagram of SRS insertion loss compensation provided by an embodiment of the present application. As shown in Figure 8, the terminal device has t1r4 capability, that is, it has 1 transmitting antenna and 4 receiving antennas, where antenna 1 is a shared antenna for transmitting and receiving. When the base station configures the terminal device with the t1r4SRS antenna rotation function, or when the terminal device triggers the SRS antenna rotation function, the SRS signal will be transmitted in turn on antennas 1, 2, 3, and 4. The base station receives SRS1, SRS2, SRS3, and SRS4 in turn. By measuring these SRS signals, the channel quality between the base station and the four antennas of the terminal device can be known. However, the SRS1, SRS2, SRS3, and SRS4 strengths measured by the base station actually include the IL from the PA to different antennas, namely IL1, IL2, IL3, and IL4. Therefore, if the base station can accurately know the IL corresponding to the SRS channel, then the impact of the corresponding IL can be subtracted from the measurement results.

[0193] Therefore, the embodiment of the present application introduces insertion loss reporting corresponding to SRS transmission signals corresponding to different antennas in the terminal device.

[0194] The following describes the static reporting method:

[0195] Assuming a terminal device has one transmit antenna and four receive antennas on a certain frequency band, the most direct approach is for the terminal device to directly report the SRS insertion loss corresponding to the four receive antennas used on that frequency band as the terminal device's capabilities. In this way, when the base station schedules t1r4 (1 transmit, 4 receive) SRS transmissions on that frequency band, it can directly obtain this information from the terminal device's capabilities and make compensation.

[0196] Optionally, the SRS insertion loss capability may be reported in frequency bands.

[0197] Optionally, the SRS insertion loss capability can be reported as an absolute value (corresponding to at least one of the above-mentioned insertion loss absolute values), such as IL1 = A dB, IL2 = B dB, IL3 = C dB, and IL4 = D dB. The terminal device can then directly report these insertion loss values ​​as corresponding to the t1r4 capability, such as {A, B, C, D}.

[0198] Optionally, the SRS insertion loss capability can be reported as relative values, such as IL1 = A dB, IL2 = B dB, IL3 = C dB, and IL4 = D dB. The terminal device can then report these insertion loss values ​​relative to each other. For example, based on IL1, the corresponding t1r4 capability can be reported, such as {BA, CA, DA}, where {BA, CA, DA} correspond to antennas 2, 3, and 4, respectively; or {0, BA, CA, DA}; or {AE, BE, CE, DE}, where E can be the absolute insertion loss value corresponding to a specific antenna other than the four receiving antennas.

[0199] Optionally, the SRS insertion loss capability can be reported according to intervals, for example, interval 1 is defined as 0≤IL<2dB, interval 2 is 2≤IL<4dB, interval 3 is 4≤IL<6, and interval 4 is 6≤IL<8 (interval 4 can also be expressed as 6≤IL, that is, there is no IL upper limit). The terminal device indicates the IL interval according to the actual absolute value and / or relative value of the insertion loss.

[0200] It's important to note that the insertion loss capability reported by a terminal device corresponds to its SRS antenna rotation capability, "srs-TxSwitch." For example, in the example above, the terminal device has four receive antennas, but can only switch the PA to two of them for SRS transmission. In this case, the SRS antenna rotation capability "srs-TxSwitch" reported by the terminal device is t1r2. Therefore, the terminal device's SRS IL reporting corresponds to t1r2, not to the four receive antennas.

[0201] The following describes the dynamic reporting method:

[0202] Compared to static reporting, dynamic SRS IL reporting is more flexible, especially considering that the actual transmit and receive antennas of a terminal device may change. For example, a terminal device may have multiple transmit and / or receive antennas. Sometimes, due to human influences such as gripping, some of the antennas may be blocked, resulting in poor performance. In this case, the terminal device will switch its transmit or receive antenna, which will cause the SRS IL to change.

[0203] Figure 9 is a schematic diagram of a receiving antenna switching provided by an embodiment of the present application. As shown in Figure 9, the terminal device has 5 antennas in a certain frequency band, and the terminal device will select 4 of them for transmission and / or reception. Initially, the terminal device uses antennas 1, 2, 3, and 4 for transmission and / or reception. When antenna 4 is blocked by a person's hand, the terminal device can select antenna 5 to replace antenna 4. At this time, antennas 1, 2, 3, and 5 will be used for transmission and / or reception. In this way, the SRS transmitted by the PA is transmitted using antennas 1, 2, 3, and 4, instead of being transmitted using antennas 1, 2, 3, and 5. Therefore, after considering this situation, the dynamic reporting of the SRS IL will be closer to the actual situation of the terminal device.

[0204] Optionally, the dynamic SRS IL reporting may be implemented based on a base station request or an event trigger.

[0205] The following describes a method based on a base station request:

[0206] In this manner, the base station may, as needed, inquire about the SRS IL of the terminal device through RRC signaling or MAC CE when configuring the terminal device to perform SRS antenna rotation transmission (or before or after).

[0207] Optionally, the base station may query the SRS IL based on the SRS antenna transmission capability reported by the terminal device (such as t1r4, t1r2, etc.). In this way, the terminal device reports the SRS IL according to the SRS antenna transmission capability, corresponding to different SRS antenna logical ports.

[0209] S1001. The terminal device reports the SRS antenna rotation transmission capability of the terminal device.

[0210] Optionally, the SRS antenna transmission capability of the terminal device may be t1r4 or t1r2.

[0211] S1002. The base station configures SRS antenna rotation transmission resources (set) (corresponding to the first uplink reference signal antenna rotation transmission resource configuration in the above embodiment).

[0212] Optionally, the SRS antenna rotation transmission resource (set) configured by the base station may correspond to t1r4 or t1r2.

[0213] S1003. The base station inquires the terminal device about the insertion loss corresponding to the SRS antenna rotation transmission capability (eg, t1r4 or t1r2) (corresponding to the first request mentioned above).

[0214] Optionally, S1002 may be executed before S1003, or after S1003, or simultaneously.

[0215] S1004. The terminal device reports the SRS IL insertion loss corresponding to the SRS antenna rotation transmission capability.

[0216] Exemplarily, the terminal device may report the SRS IL insertion loss corresponding to antennas 1, 2, 3, and 4, respectively. In another exemplary embodiment, the terminal device may report the SRS IL insertion loss corresponding to antennas 1 and 2, respectively. For example, if the terminal device's SRS antenna rotation capability is t1r4, the SRS IL insertion loss corresponding to t1r4 is reported. In another example, if the terminal device's SRS antenna rotation capability is t1r2, the SRS IL insertion loss corresponding to t1r2 is reported.

[0217] Optionally, in FIG10 , S1002 and S1003 are sent via one signaling; in other embodiments, S1002 and S1003 may be sent via different signaling.

[0218] Optionally, the base station can also query the SRS IL based on the SRS antenna rotation resources configured for the terminal device. This query method mainly considers that when the terminal device reports multiple SRS antenna rotation capabilities (such as t1r4, t1r2), the base station will select one of them to configure the SRS antenna rotation resources for SRS transmission. Therefore, the terminal device can implicitly derive which antenna ports the SRS IL to be reported corresponds to from the SRS antenna rotation resources configured by the base station. For example, if the SRS antenna rotation resources configured by the base station correspond to the t1r2 capability, then the terminal device reports the SRS IL corresponding to t1r2.

[0219] FIG11 is a flow chart of another communication method provided in an embodiment of the present application. As shown in FIG11 , the method includes:

[0220] S1101. The terminal device reports the SRS antenna rotation transmission capability of the terminal device.

[0221] Optionally, the SRS antenna transmission capability of the terminal device may be t1r4 or t1r2.

[0222] S1102: The base station configures SRS antenna rotation transmission resources (set) (corresponding to the first uplink reference signal antenna rotation transmission resource configuration in the above embodiment).

[0223] Optionally, the SRS antenna rotation transmission resource (set) configured by the base station may correspond to t1r2.

[0224] S1103 : The base station inquires about the insertion loss corresponding to the SRS antenna rotation transmission resource (set) (eg t1r4 or t1r2 ) (corresponding to the first request mentioned above).

[0225] Optionally, S1102 may be executed before S1103, or after S1103, or simultaneously.

[0226] S1104. The terminal device reports the SRS IL insertion loss corresponding to the SRS antenna rotation transmission resource (set).

[0227] Exemplarily, the terminal device reports the SRS IL insertion losses corresponding to antennas 1 and 2 respectively.

[0228] Optionally, in FIG11 , S1102 and S1103 are sent via one signaling; in other embodiments, S1102 and S1103 may be sent via different signaling.

[0229] The following description is based on event triggering:

[0230] When the terminal device's transmitting and receiving antennas change due to reasons such as human body occlusion, the terminal device can further update the SRS IL through an event-triggered method. The event-triggered method can have the following scenarios.

[0231] The first scenario is: as long as the terminal device receives the SRS antenna rotation resource configuration configured by the base station, it will trigger the terminal device to report the corresponding SRS IL at a certain time.

[0232] Optionally, the reported value may correspond to the SRS antenna rotation transmission capability, or may correspond to the SRS antenna rotation transmission resource configuration.

[0233] The second scenario is: when the SRS insertion loss of the terminal device (corresponding to the at least one first insertion loss value mentioned above) changes by more than a certain threshold (corresponding to the at least one second insertion loss value mentioned above) compared to the previously reported value (corresponding to the at least one second insertion loss value mentioned above), the terminal device is triggered to report a new SRS IL.

[0234] Optionally, this scenario can be combined with a static reporting method.

[0235] Optionally, the terminal device may initially report an SRS IL. Later, when the receiving and / or transmitting antennas of the terminal device change due to reasons such as human body occlusion, the terminal device may further update the SRS IL in an event-triggered manner.

[0236] Optionally, the action of reporting the updated SRS IL may be triggered only when the base station is configured with SRS antenna rotation resources, or may be performed when the updated SRS IL is reported when the SRS antenna rotation resources are not configured. In comparison, the method of triggering only when the base station is configured with SRS antenna rotation resources will save more signaling. For example, the terminal device reports the updated SRS IL to the base station only when it receives SRS antenna rotation resources. Before this, if the SRS IL has been updated multiple times, the terminal device reports the SRS IL after the last update. Compared with the solution of reporting the updated SRS IL to the base station every time the SRS IL is updated, it saves more signaling. Optionally, if the terminal device receives SRS antenna rotation resources, but the latest SRS IL is no different from the last reported SRS IL, the terminal device may report the SRS IL again, or the terminal device may no longer report the SRS IL until the terminal device receives SRS antenna rotation resources next time and determines whether the latest SRS IL is no different from the last reported SRS IL.

[0237] Optionally, this scenario can be combined with a dynamic reporting method.

[0238] Optionally, when the newly received SRS antenna rotation resource configuration is the same as the last received SRS antenna rotation resource configuration, if the corresponding SRS IL changes by more than a certain threshold compared to the last SRS IL reported by the terminal device, the terminal device is triggered to report a new SRS IL. If the SRS IL change is lower than the threshold, the terminal device will not be triggered to report a new SRS IL.

[0239] Optionally, in the above-mentioned SRS IL reporting method, the base station may additionally allow the terminal device to report the SRS IL through “enable” signaling, or may prevent the terminal device from reporting the SRS IL through “disable” signaling.

[0240] In an embodiment of the present application, the terminal device SRS IL reporting method can enable the terminal device to report the actual SRS insertion loss value to the base station. When measuring SRS and evaluating channel conditions, the base station can remove the impact of SRS IL, so that the base station can more accurately evaluate the downlink channel.
