Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication, and more particularly, to a terminal, a network device, a communication method, a system, an electronic device, and a storage medium. Background Art

[0002] With the development of communication technologies, according to the fifth-generation mobile communication (5G) technology, a terminal can support the SRS antenna switching capability of transmitting sounding reference signals (SRS) through multiple transmission links in a polling manner. However, due to certain hardware limitations, the state of the SRS antenna switching function of the terminal may change. For example, the terminal may turn off the SRS antenna switching function. Since the terminal only notifies the network device whether it supports the SRS antenna switching capability and does not notify whether the SRS antenna switching function is turned on, when the terminal changes the on / off state of the SRS antenna switching function, the network device may unreasonably schedule network resources and change the data transmission path based on inaccurate channel estimation, while the terminal may still work using the previous receiving link, resulting in problems such as a decrease in the transmission rate between the terminal and the network device, high power consumption of the terminal, and waste of network resources.

[0039] To facilitate the understanding of the concept of the present disclosure, before describing the present disclosure in detail, some terms of the present disclosure are first explained.

[0040] In the present disclosure, a "terminal" may be a device for providing voice and / or data connectivity to a user, and it may also be referred to as a user equipment (UE), a terminal device, a mobile station (MS), a mobile terminal (MT), a user station (SS), a remote terminal, a wireless terminal, or a receiving point, etc. A terminal according to the present disclosure may be a device with wireless communication capabilities. For example, examples of terminals may include, but are not limited to, at least one of a smart phone, a tablet personal computer (PC), a mobile phone, a video phone, an e-book reader, a desktop PC, a laptop computer, a netbook computer, a workstation, a server, a personal digital assistant (PDA), a portable multimedia player (PMP), an MP3 player, a mobile medical device, a camera, a wearable device, a vehicle-mounted device, etc.

[0041] In addition, in the present disclosure, a "network device" may be any device that provides wireless access to a network for a terminal, and it may also be referred to as a network node, a base station (BS), a core network node, or a network server, etc. Examples of network devices according to the present disclosure may include, but are not limited to, a transmit point (TP), a transmit-receive point (TRP), an enhanced (or "evolved") base station (eNodeB or eNB), a 5G base station (gNB), a macro cell, a femto cell, wireless fidelity (WiFi), an access point (AP), or other devices with wireless capabilities.

[0042] The following will refer to Figure 1 and Figure 2 to describe an example application scenario of communication processing between a terminal and a network device.

[0043] In Figure 1 and Figure 2In this case, the following assumptions are made first: The terminal is a terminal with dual Subscriber Identity Module (SIM) cards (i.e., SIM1 and SIM2) and supports the Dual SIM Dual Active (DSDA) function. SIM1 and SIM2 share the switch for the round-robin transmission of Sounding Reference Signals (SRS), and the terminal is configured with 7 transceiver antennas (the first antenna to the seventh antenna) and three gating switches (the first switch to the third switch). In this situation, Multiple-Input Multiple-Output (MIMO) technology can be used to transmit downlink signals through 4 links between the terminal and a network device (e.g., a base station), that is, the 4×4 MIMO transmission mode. It should be understood that these assumptions are only examples here, and the present disclosure is not limited thereto.

[0044] First, refer to Figure 1 , when the terminal independently operates on the first frequency band (e.g., N41) using SIM1, the terminal can turn on the first switch and the third switch to enable the SRS to be transmitted sequentially using the first antenna, the second antenna, the third antenna, and the fourth antenna. Similarly, when the terminal independently operates on the second frequency band (e.g., N78) using SIM2, the terminal can turn on the second switch and the third switch to enable the SRS to be transmitted sequentially using the fourth antenna, the fifth antenna, the sixth antenna, and the seventh antenna. In this way, the round-robin transmission mode of the SRS is achieved through the gating switch, that is, the SRS antenna switching function is in the on state.

[0045] However, in Figure 1 , there is a hardware link conflict logic: Both SIM1 and SIM2 need to use the link controlled by the third switch to transmit the SRS. Figure 1SIM1 and SIM2 in it jointly control the third switch of the fourth antenna, but their control logics for the third switch are inconsistent and the third switch can only have one control logic. Therefore, in this case, if SIM1 and SIM2 both support the SRS antenna switching function (for example, when SIM1 operates in the first frequency band N41 and SIM2 operates in the second frequency band N78), there will be a conflict at the third switch. Therefore, it is necessary to deactivate / turn off the SRS antenna switching function to ensure the normal implementation of the DSDA function for the first frequency band used by SIM1 and the second frequency band used by SIM2. For example, assume that SIM1 is using the network to watch a video live stream, browse videos, etc., which require high throughput services, and SIM2 receives an incoming call or uses other services, which will cause the entry into the DSDA scenario. In this case, the terminal will control (for example, deactivate or turn off) the SRS antenna switching function to ensure the normal implementation of the DSDA function.

[0046] In this way, the terminal that transmits SRS in a polling manner can turn off the SRS antenna switching function. Although only the above simple hardware link conflict logic is shown in Figure 1 , the terminal may also turn off the SRS antenna switching function due to various other limitations or reasons, and the application scenarios of the present disclosure are not limited to this.

[0047] The transmission link between the terminal and the network device will be described below with reference to Figure 2 . For the sake of simplicity, only SIM1, the first switch, the third switch, and the first to fourth antennas in the terminal are shown in Figure 2 . Referring to Figure 2 , SIM1 of the terminal communicates with a network device (for example, a base station). Among them, when the SRS antenna switching function of the terminal is enabled, SIM1 can use the transmission links SRS_1, SRS_2, SRS_3, and SRS_4 to transmit SRS to the network device in sequence. The network device estimates the channel quality of the downlink according to the SRS sent by the terminal for resource scheduling, and sends signals to the terminal using the downlink, and SIM1 can use the reception links RX_1, RX_2, RX_3, and RX_4 to receive signals from the network device.

[0048] When there is a situation as described with reference to Figure 1When the described conflict occurs, the terminal deactivates / turns off the SRS antenna switching function, and then the terminal uses only one transmit link (e.g., SRS_1) to send SRS. In this case, the network device does not know that the terminal has turned off the SRS antenna switching function and can only receive SRS on one link (e.g., SRS_1), so the network device will erroneously estimate that the terminal has only one receive link (e.g., RX_1) available, and the other receive links RX_2, RX_3, and RX_4 are all unavailable. Accordingly, the network device will not transmit signals to the terminal on the receive links RX_2, RX_3, and RX_4.

[0049] In addition, since the terminal reports the SRS antenna switching capability to the network device only when the network device (e.g., by sending a UeCapabilityEnquiry message) queries the terminal's capabilities, the network device can only know whether the terminal supports the SRS antenna switching capability. When the terminal deactivates / turns off the SRS antenna switching function, the network device does not know that the state of the terminal's SRS antenna switching function has changed. Therefore, when the terminal changes the on / off state of the SRS antenna switching function, there will be many problems.

[0050] For example, since the network device still detects the previous links (e.g., SRS_1, SRS_2, SRS_3, and SRS_4) and obtains inaccurate channel estimation results, it may not be able to allocate resources reasonably. For example, a terminal that has turned off the SRS antenna switching function still continues to work with the maximum number of receive links (in this case, the maximum number of receive links is only used for diversity reception). However, the diversity reception of the maximum number of receive links results in relatively high power consumption. For example, due to the out-of-synchronization of the on / off state of the SRS antenna switching function, the network device may use unreasonable resource allocation, and the data transmission channel between the network device and the terminal may change from multiple links (e.g., 4 links) to the transmission of 1 link, resulting in a possible sharp drop in the transmission rate. For example, even when the signal reception state is good, there will be a phenomenon of reduced transmission rate. For example, in the case of 4 RX links, the rate drops to 1 / 4 of the original rate or even lower, which will affect the user experience. In summary, when the SRS antenna switching function of the terminal changes, the terminal may still work with the previous receive links, and the network device may schedule network resources unreasonably, resulting in problems such as a decrease in the transmission rate between the terminal and the network device and relatively high power consumption of the terminal.

[0051] In view of the above problems, the present disclosure proposes a terminal, a network device, a communication method, a system, an electronic device, and a storage medium that at least solve the above problems. The following will refer to Figures 3 to 9 Describe the terminal, the network device, the communication method, and the system according to the embodiments of the present disclosure.

[0052] Figure 3 A flowchart showing a communication method executed by a terminal according to an embodiment of the present disclosure.

[0053] Referring to Figure 3 , in operation S310, in response to the terminal enabling the SRS antenna switching function, the antenna of the terminal transmits SRS in a polling manner. For example, as Figure 2 shown, when the maximum number of transmission links of the antenna of the terminal is 4 and the terminal enables the SRS antenna switching function, SRS is transmitted sequentially using 4 transmission links (e.g., SRS_1, SRS_2, SRS_3, and SRS_4) respectively for channel estimation and beam management, etc.

[0054] According to an embodiment, when the network device sends a UeCapabilityEnquiry message for querying the terminal capabilities to the terminal, the terminal reports its SRS antenna switching capabilities to the network device through a UeCapabilityInformation message, where the UeCapabilityInformation message indicates whether the terminal supports the SRS antenna switching function and the situation of the terminal supporting the SRS antenna switching function in each frequency band.

[0055] Specifically, regarding supporting the SRS antenna switching function, according to Section 6.3.3 of the 3rd Generation Partnership Project (3GPP) Technical Specification 38.331, the SRS antenna round-robin types are defined as follows:

[0056]

[0057] That is to say, the UeCapabilityInformation message can indicate whether the terminal supports the SRS antenna switching function and the antenna round-robin types in each frequency band in the case of supporting the SRS antenna switching function (e.g., t1r2, t1r4, t2r4, t1r4 - t2r4, t1r1, t2r2, t4r4). To avoid obscuring the present disclosure with unnecessary details, no detailed description is provided here.

[0058] According to an embodiment of the present disclosure, when the network device receives SRS, it can estimate the channel quality (e.g., estimate the channel quality based on SRS and perform resource allocation and scheduling), and send the corresponding response signal (e.g., regarding resources and related transmission information, etc.) to the terminal, and the terminal receives the signal sent by the network device through the receiving link.

[0059] In operation S320, in response to the terminal turning off the SRS antenna switching function, determine the signal reception quality of the current terminal according to the specific parameters of each enabled receiving link. For example, when the terminal disables / turns off the SRS antenna switching function due to hardware limitations, the terminal detects the specific parameters of each currently enabled receiving link and determines the current signal reception quality of the terminal according to the specific parameters.

[0060] Here, the signal reception quality determined according to the specific parameters can be used as an indicator for measuring the signal reception environment or signal reception state of the terminal. The specific details of determining the signal reception quality according to the specific parameters will be described in detail below.

[0061] First, in response to the terminal turning off the SRS antenna switching function, determine the signal level of each receiving link according to the specific parameters of each enabled receiving link. According to an embodiment of the present disclosure, the specific parameters may include at least one of reference signal received power (RSRP), signal-to-noise ratio (SNR), and reference signal received quality (RSRQ). Here, in order to avoid obscuring the present disclosure with unnecessary details, the present disclosure does not describe in detail the process of detecting the specific parameters of the receiving link.

[0062] According to an embodiment of the present disclosure, each specific parameter can be divided into multiple parameter levels according to a specific range, and the signal level of the receiving link is determined by assigning different weights to the multiple specific parameters.

[0063] For example, the first weight w1 can be applied to the parameter level of RSRQ, the second weight w2 can be applied to the parameter level of RSRP, and the third weight w3 can be applied to the parameter level of SNR, where w1 + w2 + w3 = 1, and the weighted sum of the parameter levels of RSRQ, RSRP, and SNR can be determined as the signal level of the receiving link.

[0064] For example, RSRQ, RSRP, and SNR can each be divided into a total of 30 parameter levels with reference to Table 1 below. For example, when the RSRQ of the receiving link is -7.9 dB, the RSRP is -107 dB, and the SNR is 9.5 dB, the parameter level corresponding to RSRQ is 11, the parameter level corresponding to RSRP is 5, and the parameter level corresponding to SNR is 14. Assuming w1 is 0.2, w2 is 0.2, and w3 is 0.6, then the signal level of the receiving link is determined to be 11×0.2 + 5×0.2 + 14×0.6 = 11.6.

[0065] Table 1

[0066]

[0067]

[0068] Here, the above Table 1 and weight allocation are only examples, and the present disclosure is not limited thereto. Although a process of determining a signal level using three specific parameters is shown, the present disclosure is not limited thereto, and a signal level of a receiving link may also be determined using a single specific parameter or two specific parameters. In addition, according to an embodiment of the present disclosure, any other suitable method of determining or evaluating a signal level of a receiving link based on parameters of the receiving link may also be used, and the present disclosure does not limit this.

[0069] In the present disclosure, the signal reception quality of a terminal may be evaluated based on the signal levels of respective receiving links. According to an embodiment of the present disclosure, based on the signal levels of respective receiving links and the block error rate (BLER) of respective receiving links, the signal reception quality of the current terminal is determined.

[0070] Specifically, based on the number of receiving links among the enabled receiving links whose signal levels and block error rates (such as downlink BLER) satisfy threshold conditions, the signal reception quality of the current terminal is determined. That is, according to the signal level and block error rate of each receiving link, the number of receiving links of the terminal that meet a predetermined condition is determined to evaluate the signal reception quality of the terminal, for example, poor, medium, and good signal reception quality. The following describes this operation in detail.

[0071] According to an embodiment of the present disclosure, based on the comparison result of the signal level of each receiving link with a first threshold and / or the comparison result of the BLER of each receiving link with a second threshold, the number of receiving links that meet the threshold conditions is determined, thereby determining the signal reception quality.

[0072] For example, a signal level of a receiving link being greater than or equal to a first threshold T1 may indicate a good reception environment. On the contrary, a signal level of a receiving link being less than the first threshold T1 may indicate a poor reception environment. Further, for example, a third threshold T3 greater than the first threshold T1 may be further set. A signal level of a receiving link being greater than or equal to the third threshold T3 may indicate a good reception environment, a signal level of a receiving link being greater than or equal to the first threshold T1 and less than the third threshold T3 may indicate a medium reception environment, and a signal level of a receiving link being less than the first threshold T1 may indicate a poor reception environment.

[0073] For example, a block error rate of a receiving link (such as a downlink BLER) being less than or equal to a second threshold T2 may indicate a good receiving environment. On the contrary, a block error rate of a receiving link (such as a downlink BLER) being greater than the second threshold T2 may indicate a poor receiving environment. For another example, a fourth threshold T4 less than the second threshold T2 may be further set. A block error rate of a receiving link (such as a downlink BLER) being less than or equal to the fourth threshold T4 may indicate a good receiving environment. A signal level of the receiving link being greater than the fourth threshold T4 and less than or equal to the second threshold T2 may indicate a medium receiving environment. A signal level of the receiving link being greater than the second threshold T2 may indicate a poor receiving environment.

[0074] Refer to Figure 4 A description is given of an example process for determining that the signal reception quality is good, medium, or poor. Figure 4 is a flowchart showing a process of determining signal reception quality according to an embodiment of the present disclosure. Figure 5 is showing according to an embodiment of the present disclosure Figure 4 a diagram of an example application scenario. It is assumed that the maximum number of receiving links of the terminal is 4.

[0075] In operation S410, the number of currently enabled receiving links of the terminal is determined. For example, in response to the terminal turning off the SRS antenna switching function or a specific parameter of the terminal changing, the number of currently enabled receiving links is determined.

[0076] In operation S420, it is determined whether there is at least one receiving link among the enabled receiving links whose signal level is greater than or equal to a third threshold T3 and whose block error rate (such as a downlink BLER) is less than or equal to a fourth threshold T4.

[0077] For example, when the number of enabled receiving links determined in operation S410 is not equal to 1, it is determined whether there is at least one receiving link that meets the threshold conditions based on the third threshold T3 and the fourth threshold T4, and when the number of enabled receiving links determined in operation S410 is equal to 1, it is determined whether this receiving link is a receiving link that meets the threshold conditions based on the third threshold T3 and the fourth threshold T4.

[0078] When the result of operation S420 is yes, in operation S440, it is determined that the signal reception quality of the current terminal is good. In this case, the signal level and the block error rate of at least one receiving link meet high requirements, the receiving environment is good, and the opening and closing state of the receiving link corresponding to the case of good signal reception quality can be determined (for example, only one receiving link with a high signal level can be used). This will be described in detail in the description of operation S330 below.

[0079] When the operation S420 is NO, perform operation S430 to determine whether there are at least X receiving links in the enabled receiving links whose signal levels are greater than or equal to the first threshold T1 and the block error rate (such as the downlink BLER) is less than or equal to the second threshold T2, where X can be an integer greater than 1 and less than or equal to the number of receiving links, and can be determined empirically. Here, for an antenna with up to 4 receiving links, X can be 2.

[0080] In operation S430, if the number of enabled receiving links is 1, directly determine that operation S430 is NO and perform operation S460. That is, if only one receiving link is enabled and this receiving link does not meet the threshold conditions based on the third threshold T3 and the fourth threshold T4, it is determined that the signal reception quality is poor.

[0081] When the operation S430 is YES, in operation S450, determine that the signal reception quality of the current terminal is medium. In this case, the signal levels and block error rates of at least X (for example, at least two) receiving links generally meet the requirements, the receiving environment is medium, and the opening and closing states of the receiving links corresponding to the case of medium signal reception quality (such as using at least two receiving links) can be determined. This will be described in detail in the following description of operation S330.

[0082] When the operation S430 is NO, determine that the signal reception quality of the current terminal is poor. That is, when there is no receiving link that meets the threshold conditions based on the third threshold T3 and the fourth threshold T4 or there are not at least X (such as at least two) receiving links that meet the threshold conditions based on the first threshold T1 and the second threshold T2, perform operation S460 to determine that the signal reception quality of the current terminal is poor.

[0083] Although only the embodiments in which the signal reception quality includes good, medium, and poor are shown here, the present disclosure is not limited thereto. Thresholds can be arbitrarily set to determine the signal reception quality, and the levels or intervals of the signal reception quality can be arbitrarily divided, which will not be described in detail here.

[0084] In the above-described manner, the signal reception quality of the current terminal can be determined according to the specific parameters of each enabled receiving link. Now, return to Figure 3 Continue the description.

[0085] In operation S330, based on the signal reception quality of the terminal, determine the optimal opening and closing states of all receiving links of the terminal. Specifically, based on the signal reception quality of the terminal, determine the optimal opening and closing states of all receiving links corresponding to the signal reception quality (that is, the opening and closing states of each link suitable for the current receiving environment), and adjust the opening and closing states of the receiving links according to the enabled receiving links.

[0086] According to an embodiment of the present disclosure, when the terminal changes the SRS antenna switching function, the terminal no longer transmits SRS in a polling manner. Since the messages regarding whether the SRS antenna switching function is enabled between the terminal and the network device are out of sync, the network device evaluates the signal quality of the downlink receiving link based on the SRS sent by the terminal. In this case, the network device will consider that the signal quality of the receiving link where the terminal no longer transmits SRS deteriorates instantaneously (in fact, the signal reception quality of the terminal does not deteriorate). Therefore, the network device will not send signals to the terminal on these links. Thus, the terminal can infer that the receiving links unrelated to the transmission of SRS will no longer receive independent data sent by the network device through MIMO. Therefore, the receiving links can be adjusted according to the optimal on / off state to achieve purposes such as power consumption savings.

[0087] According to an embodiment of the present disclosure, based on the fact that the signal reception quality of the terminal is good, it can be determined that one receiving link with the highest signal level among the enabled receiving links is in the on state. That is to say, when the signal reception quality is good, the currently enabled receiving links that meet the threshold conditions can meet the requirements. In order to avoid the use of unnecessary receiving links, only the receiving link with the best reception effect can be retained.

[0088] For example, when the number of enabled receiving links is 4, and there is at least one receiving link whose signal level is greater than or equal to the third threshold T3 and the block error rate (such as the downlink BLER) is less than or equal to the fourth threshold T4, based on the good signal reception quality, some receiving links can be turned off, and only one receiving link with the highest signal level can be retained. For example, referring to Figure 5 , taking the SIM1 of the terminal as an example, only the first receiving link RX_1 with the highest signal level is enabled, and the second receiving link RX_2 to the fourth receiving link RX_4 with relatively low signal levels are disabled.

[0089] For another example, when the number of enabled receiving links is 1, and the signal level of this receiving link is greater than or equal to the third threshold T3 and the block error rate (such as the downlink BLER) is less than or equal to the fourth threshold T4, based on the good signal reception quality, the on state of this receiving link can be maintained.

[0090] According to an embodiment of the present disclosure, based on the fact that the signal reception quality of the terminal is medium, it can be determined that the first X receiving links with the highest signal levels among the enabled receiving links are in the on state. That is to say, when the signal reception quality is medium, the currently enabled receiving links can generally meet the requirements. In order to avoid the use of unnecessary receiving links, only X receiving links can be used.

[0091] For example, when the number of enabled receive links is 4, and there are at least 2 receive links with a signal level greater than or equal to the first threshold T1 and a block error rate (such as downlink BLER) less than or equal to the second threshold T2, based on the medium signal reception quality, some of the receive links can be turned off, and only the top 2 receive links with the highest signal level are retained.

[0092] For another example, when the number of enabled receive links is 2, and there are at least 2 receive links with a signal level greater than or equal to the first threshold T1 and a block error rate (such as downlink BLER) less than or equal to the second threshold T2, based on the medium signal reception quality, the current enabled receive links can be kept in the on state.

[0093] According to an embodiment of the present disclosure, based on the poor signal reception quality of the terminal, it can be determined to turn on at least one currently disabled receive link until the signal reception quality changes to medium or good, or until all receive links are in the on state. That is to say, when the signal reception quality is poor, the currently enabled receive links cannot meet the requirements, and other receive links need to be turned on to improve the reception effect.

[0094] For example, when the number of enabled receive links is 1, based on the poor signal reception quality, other receive links can be turned on respectively until the signal reception quality changes to medium or good, or until all receive links are in the on state.

[0095] In the above - described manner, the optimal on - off state of the receive links suitable for the current situation can be determined based on the signal reception quality, and the receive links can be adjusted by using the determined optimal on - off state. For example, in the case where the signal reception state is not good enough, the disabled receive links are enabled respectively to receive signals using as many receive links as possible.

[0096] In addition, the communication method performed by the terminal according to an embodiment of the present disclosure may further include: in response to a change in the signal reception quality of the terminal, determining the optimal on - off state of all receive links of the terminal based on the changed signal reception quality of the terminal.

[0097] For example, the terminal can monitor or detect specific parameters of the enabled receive links according to a predetermined rule (for example, in real - time or periodically), and in response to a change in the specific parameters of the terminal, the terminal can determine whether the signal reception quality of the terminal has changed through operation S320 according to the changed specific parameters.

[0098] For example, in response to adjusting the on - off state of the receive links according to the determined optimal on - off state, the terminal can determine whether the signal reception quality of the terminal has changed through operation S320 according to the adjusted receive links.

[0099] The terminal can repeatedly determine the signal reception quality of the terminal every time a specific parameter changes or the reception link changes its on / off state to achieve dynamic adjustment. Therefore, in addition to determining the optimal on / off state of the reception link in response to turning off the SRS antenna switching function, the terminal can also determine the optimal on / off state of the reception link according to a predetermined rule (such as in real time), so as to perform control processing on the reception link of the antenna. According to the test using the above method, each time a reception link is deactivated by the terminal, power consumption of about 20 mA+ can be saved. Therefore, the communication method executed by the terminal according to the embodiments of the present disclosure can detect the signal reception quality of the reception link by responding to the terminal turning off the SRS antenna switching function or according to a predetermined rule, and determine the optimal usage strategy of the reception link based on the detected signal reception quality, so that the terminal can dynamically adjust the number of enabled reception links according to the communication situation, thereby reducing the power consumption of the terminal while ensuring better signal quality.

[0100] In addition, the communication method executed by the terminal according to the embodiments of the present disclosure may further include: in response to the SRS antenna switching function of the terminal being changed, the terminal synchronizes the status information to the network device by a preset method.

[0101] According to the embodiments of the present disclosure, the terminal can report the two states of turning on and off the SRS antenna switching function to the network device. Specifically, in response to the change of the SRS antenna switching function of the terminal, the terminal can also notify the status information of the SRS antenna switching function to the network device by a preset method.

[0102] According to the embodiments of the present disclosure, the preset method includes: adding a field representing the status information in the registration request signaling of the mobility registration updating process, and / or adding a field representing the status information in the medium access control (MAC) control element (CE) message.

[0103] For the mobility registration updating process, the terminal can notify the status of the SRS antenna switching function to the network device by adding a field indicating the status of the SRS antenna switching function in the registration request signaling of the mobility registration updating process.

[0104] Generally, the terminal notifies the network device whether it supports the SRS antenna switching capability only through the UeCapabilityInformation message during initial registration. However, the processing of the above notification method not only has a cumbersome process, but also consumes a large amount of wireless resources because all the capabilities of the terminal (such as SRS, band information, carrier aggregation (CA) support, discontinuous reception (DRX) information, etc.) are carried in the UeCapabilityInformation message and each notification requires the cooperation of the base station and the core network.

[0105] According to an embodiment of the present disclosure, as long as the location information or specific capabilities of the terminal (such as the support for Standalone Architecture (SA) or Non-Standalone Architecture (NSA)) change, the terminal triggers a mobility registration update process and sends a Registration Request signaling including the status information of the SRS antenna switching function to the network device (such as the core network).

[0106] For example, the status of the SRS antenna switching function can be indicated by adding a field srs_switch to the Registration Request signaling. The specific definition of this field is as follows:

[0107]

[0108] In this way, by synchronizing the SRS antenna switching function by adding a field to the Registration Request signaling and triggering the status synchronization process only when the terminal status changes, unnecessary interaction times can be reduced and the signaling overhead is small.

[0109] For the MAC CE message, the terminal can also notify the network device of the status of the SRS antenna switching function by adding the above field srs_switch indicating the status of the SRS antenna switching function to the MAC CE command.

[0110] Generally, when the terminal is in the connected state, it interacts with the network device (such as the base station) at the MAC layer through the MAC CE command. According to an embodiment of the present disclosure, the SRS antenna switching function can be kept synchronized between the terminal and the network device by adding a field indicating the status of the SRS antenna switching function to the MAC CE command.

[0111] In this way, by adding fields to the MAC CE command to synchronize the SRS antenna switching function, a network device (e.g., a base station) can directly process MAC messages with a relatively small time delay.

[0112] According to an embodiment of the present disclosure, by notifying a network device of a change in the SRS antenna switching function by synchronizing the status information of the SRS antenna switching function, the network device can timely adjust the SRS signal detection strategy and perform resource allocation and scheduling more reasonably.

[0113] Figure 6 It shows a communication method performed by a network device according to an embodiment of the present disclosure.

[0114] Refer to Figure 6 , in operation S610, detect the SRS sent by the terminal. For example, as described above, the network device sends a UeCapabilityEnquiry message for querying the terminal capabilities to the terminal and receives a UeCapabilityInformation message from the terminal, where the UeCapabilityInformation message indicates whether the terminal supports the SRS antenna switching function.

[0115] According to an embodiment of the present disclosure, when the terminal transmits the SRS in a polling manner with the SRS antenna switching function enabled, the network device detects the SRS for corresponding multiple links. For example, the network device uses 4 links to detect the SRS.

[0116] In operation S620, in response to receiving the status information synchronized by the terminal in a preset manner, adjust the detection link for detecting the SRS based on the status information. For example, when the SRS antenna switching function of the terminal changes, as described above, the network device receives the status information of the SRS antenna switching function from the terminal (e.g., a field indicating the status of the SRS antenna switching function included in the Registration Request signaling or the MAC CE command). For example, in response to receiving the status information of the terminal, the network device triggers a corresponding processing mechanism (e.g., adjusting the detection link of the SRS, etc.) according to the status information of the SRS antenna switching function.

[0117] According to an embodiment of the present disclosure, when the terminal turns off the SRS antenna switching function, the network device determines that the terminal does not transmit the SRS in a polling manner based on the field value of 0 indicating the status of the SRS antenna switching function included in the Registration Request signaling or the MAC CE command.

[0118] Generally, as described above, when the terminal initializes registration, the terminal notifies the network device of the SRS antenna switching capabilities supported by the terminal, and the network device configures the time-frequency resources for SRS. This configuration of the network device includes a resource set, where the resource set includes resource configurations for each antenna of the terminal (indicated by resource sequence numbers 0, 1, 2,... respectively). Taking the SRS antenna round-robin type of the terminal as t1r4 as an example, the network device issues four sets of resource configurations with resource sequence numbers srs-ResourceId = 0, 1, 2, 3, which respectively correspond to the four antennas of the terminal. Generally, the network device detects the SRS of the terminal on these four links and allocates scheduling resources for data transmission for the terminal according to the reception conditions of these four links.

[0119] According to an embodiment of the present disclosure, based on the status information of the terminal indicating that the SRS antenna switching function is in the off state, the network device only enables the detection link of the main path SRS. For example, when the terminal turns off the SRS antenna switching function, the terminal only transmits SRS on one antenna (usually the first antenna by default, that is, this transmission link is called the main path, corresponding to the resource sequence number 0), and this SRS is the main path SRS. When the network device receives the status information sent by the terminal, it only detects the SRS of the terminal on one link (the link with resource sequence number 0), and does not consider other links.

[0120] According to an embodiment of the present disclosure, based on the status information of the terminal indicating that the SRS antenna switching function is in the off state, the network device can also estimate the channel quality based on the reported Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI), and / or Rank Indication (RI) to perform reasonable resource allocation and scheduling for data transmission, so as to avoid a sudden drop in the rate caused by the out-of-sync status information of the SRS antenna switching function between the terminal and the network device.

[0121] According to an embodiment of the present disclosure, based on the status information of the terminal indicating that the SRS antenna switching function is in the on state, the network device can resume the SRS detection on all links.

[0122] The communication method performed by the network device according to an embodiment of the present disclosure can timely synchronize and learn the status of the SRS antenna switching function of the terminal by responding to the received status information of the terminal, so as to timely adjust the detection path of the SRS to avoid waste of network resources and avoid a decrease in the transmission rate between the terminal and the network device caused by inappropriate channel quality evaluation.

[0123] In the above, the communication method performed by the terminal and the network device has been described. Below, reference will be made toFigures 7 to 9 Describe a terminal, a network device, and a system including the terminal and the network device.
