Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a resource configuration method and related products. Background Art

[0002] In the NR R15 / 16 standard, the network configures the association between the aperiodic channel sounding reference signal (SRS) resource set (SRS resourceset) and the aperiodic SRS resource trigger (aperiodicSRS-ResourceTrigger) through radio resource control (RRC). An aperiodic SRS resource trigger can be configured to be associated with multiple aperiodic SRS resource sets, and the network can also configure multiple aperiodic SRS resource triggers; the network further triggers the aperiodic SRS resource trigger through downlink control information (DCI).

[0003] As mentioned above, since the existing technology configures the association between the non-periodic SRS resource set and the non-periodic SRS resource trigger through RRC, if it is necessary to change the association between the non-periodic SRS resource set and the non-periodic SRS resource trigger, it can only be changed through RRC reconfiguration, which will bring a lot of system overhead and high latency problems. Summary of the Invention

[0004] The embodiments of the present application disclose a resource configuration method and related products, which configure the association between aperiodic SRS resource trigger and aperiodic SRS resource set through Media Access Control (MAC), thereby avoiding RRC reconfiguration and reducing system overhead and latency.

[0005] A first aspect of an embodiment of the present application discloses a resource configuration method, which is applied to a network device. The method includes: sending a media access control element MAC CE to a terminal, wherein the MAC CE is used to configure an association between an aperiodic SRS resource trigger and an aperiodic SRS resource set.

[0006] It can be seen that in this embodiment, the network device sends a MAC CE to the terminal, wherein the MAC CE is used to configure the association between the non-periodic SRS resource trigger and the non-periodic SRS resource set; after receiving the MAC CE, the terminal can learn the association between the non-periodic SRS resource trigger and the non-periodic SRS resource set, and then select the corresponding non-periodic SRS resource set to transmit the SRS according to the non-periodic SRS resource trigger; if the association between the non-periodic SRS resource trigger and the non-periodic SRS resource set needs to be changed, the network device only needs to change the MAC CE to achieve the reconfiguration of the association between the non-periodic SRS resource trigger and the non-periodic SRS resource set without the need for RRC reconfiguration, thereby achieving the association between the non-periodic SRS resource trigger and the non-periodic SRS resource set through MAC configuration, which is conducive to avoiding RRC reconfiguration and reducing system overhead and latency.

[0007] In some possible implementations, the MAC CE includes an aperiodic SRS resource triggering ID, where the aperiodic SRS resource triggering ID is used to indicate an aperiodic SRS resource triggering that the MAC CE needs to configure.

[0008] It can be seen that in this embodiment, the MAC CE includes a non-periodic SRS resource trigger ID, which is used to indicate the non-periodic SRS resource trigger that the MAC CE needs to configure. Therefore, when the network device configures multiple non-periodic SRS resource triggers, the terminal can determine the non-periodic SRS resource trigger that the MAC CE needs to configure through the non-periodic SRS resource trigger ID.

[0009] In some possible implementations, the MAC CE further includes indication information, where the indication information is used to indicate whether the aperiodic SRS resource set is associated with the aperiodic SRS resource trigger.

[0010] It can be seen that in this embodiment, MAC CE includes indication information, which is used to indicate whether the non-periodic SRS resource set is associated with the non-periodic SRS resource trigger. Therefore, the terminal can determine whether the non-periodic SRS resource set is associated with the non-periodic SRS resource trigger through the indication information; further, when there are multiple indication information, the terminal can determine which non-periodic SRS resource sets are associated with the non-periodic SRS resource trigger through the indication information, and thus select one or more configurations from these non-periodic SRS resource sets to be associated with the non-periodic SRS resource trigger, thereby realizing the association between the non-periodic SRS resource trigger and the non-periodic SRS resource set through MAC configuration.

[0011] In some possible implementations, if the field where the indication information is located is configured as 1, the aperiodic SRS resource trigger is associated with the aperiodic SRS resource set; otherwise, the aperiodic SRS resource trigger is not associated with the aperiodic SRS resource set.

[0012] It can be seen that in this embodiment, a MAC CE may include multiple indication information, that is, there are multiple non-periodic SRS resource sets associated with the non-periodic SRS resource trigger configuration. By configuring the field where each indication information is located to 1 or 0, whether the non-periodic SRS resource set corresponding to each indication information is associated with the non-periodic SRS resource trigger is configured; if the field where the indication information is located is configured to 1, the non-periodic SRS resource trigger is associated with the non-periodic SRS resource set; otherwise, the non-periodic SRS resource trigger is not associated with the non-periodic SRS resource set; thereby, the field where the indication information is located can be changed to change the association relationship between the non-periodic SRS resource trigger and the non-periodic SRS resource set without the need for RRC reconfiguration, which is beneficial to reducing system overhead and latency.

[0013] In some possible implementations, the MAC CE further includes activation information, where the activation information is used to indicate whether to activate the aperiodic SRS resource triggering.

[0014] It can be seen that in this embodiment, the MAC CE includes activation information for indicating whether to activate the aperiodic SRS resource triggering. After receiving the MAC CE, the terminal determines whether to activate the aperiodic SRS resource triggering according to the activation information.

[0015] In some possible implementations, if the field at the location of the activation information is configured as 1, the aperiodic SRS resource triggering is activated; otherwise, the aperiodic SRS resource triggering is not activated.

[0016] It can be seen that in this embodiment, if the field where the activation information is located is configured as 1, it means that the aperiodic SRS resource trigger is activated; otherwise, it means that the aperiodic SRS resource trigger is not activated.

[0017] In some possible implementations, the MAC CE further includes carrier configuration information, wherein the carrier configuration information is used to indicate that the MAC CE applies to a normal uplink (NUL) carrier configuration or a supplementary uplink (SUL) carrier configuration.

[0018] It can be seen that in this embodiment, the MAC CE includes carrier configuration information for indicating that the MAC CE is applied to the NUL carrier configuration or the SUL carrier configuration. After receiving the MAC CE, the terminal selects the NUL carrier or the SUL carrier to transmit the SRS according to the indication of the carrier configuration information, so that the network device no longer needs to configure the carrier configuration through other configuration information, thereby further reducing the system overhead.

[0019] In some possible implementations, if the field where the carrier configuration information is located is configured as 1, the MAC CE is applied to SUL carrier configuration; otherwise, the MAC CE is applied to NUL carrier configuration.

[0020] It can be seen that in this embodiment, if the field where the carrier configuration information is located is configured to 1, it means that the MAC CE is applied to the SUL carrier configuration; otherwise, it means that the MAC CE is applied to the NUL carrier configuration; thus, the uplink carrier can be changed by changing the field where the carrier configuration information is located. The network device no longer needs to use other configuration information to change the uplink carrier for transmitting SRS, which is beneficial to reducing system overhead.

[0021] In some possible implementations, the MAC CE further includes a serving cell ID, where the serving cell ID is used to indicate a serving cell to which the MAC CE applies.

[0022] It can be seen that in this embodiment, the MAC CE includes a service cell ID for indicating the service cell to which the MAC CE is applied, that is, by setting the service cell ID in the MAC CE, it is indicated that the association between the non-periodic SRS resource trigger and the non-periodic SRS resource set when the terminal of the service cell corresponding to the service cell ID transmits SRS is the association configured by the MAC CE; thereby, the network device can select the service cell by setting the service cell ID in the MAC CE to configure the association between the non-periodic SRS resource trigger and the non-periodic SRS resource set, and can configure different associations between the non-periodic SRS resource trigger and the non-periodic SRS resource set for different service cells, which is conducive to avoiding resource conflicts.

[0023] In some possible implementations, if the serving cell to which the MAC CE applies is configured as part of a preset component carrier CC list, the MAC CE applies to all CCs in the CC list.

[0024] It can be seen that in this embodiment, if the serving cell to which the MAC CE is applied is configured as part of a preset component carrier CC list, the MAC CE is applied to all CCs in the CC list. That is, since the serving cell to which the MAC CE is applied can utilize all CCs in the CC list, the MAC CE can be applied to all CCs in the CC list.

[0025] In some possible implementations, the MAC CE further includes a bandwidth portion (BWP) identifier BWP ID, where the BWP ID is used to indicate the BWP applied by the MAC CE.

[0026] It can be seen that in this embodiment, the MAC CE includes a BWP identifier BWPID for indicating the MAC CE application, so that it can be determined that the terminal transmits the SRS through the BWP corresponding to the BWP ID. The network device does not need to indicate through other configuration information, which is conducive to reducing system overhead.

[0027] In some possible implementations, if the MAC CE is applied to a preset component carrier CC list, the BWP ID is ignored.

[0028] It can be seen that in this embodiment, if the MAC CE is applied to the preset component carrier CC list, that is, the component carrier for transmitting the SRS has been determined, the BWP ID in the MAC CE is ignored.

[0029] In some possible implementations, the MAC CE further includes a reserved bit.

[0030] It can be seen that in this embodiment, the MAC CE includes a reserved bit. When the network device needs to configure other information, it can be configured through the reserved bit without the need to configure through other configuration information, which is conducive to reducing system overhead.

[0031] A second aspect of an embodiment of the present application discloses a resource configuration method, which is applied to a terminal. The method includes: receiving a media access control element MAC CE from a network device, wherein the MAC CE is used to configure an association between an aperiodic SRS resource trigger and an aperiodic SRS resource set.

[0032] In some possible implementations, the MAC CE includes an aperiodic SRS resource triggering ID, where the aperiodic SRS resource triggering ID is used to indicate an aperiodic SRS resource triggering that the MAC CE needs to configure.

[0033] In some possible implementations, the MAC CE further includes indication information, where the indication information is used to indicate whether the aperiodic SRS resource set is associated with the aperiodic SRS resource trigger.

[0034] In some possible implementations, if the field where the indication information is located is configured as 1, the aperiodic SRS resource trigger is associated with the aperiodic SRS resource set; otherwise, the aperiodic SRS resource trigger is not associated with the aperiodic SRS resource set.

[0035] In some possible implementations, the MAC CE further includes activation information, where the activation information is used to indicate whether to activate the aperiodic SRS resource triggering.

[0036] In some possible implementations, if the field at the location of the activation information is configured as 1, the aperiodic SRS resource triggering is activated; otherwise, the aperiodic SRS resource triggering is not activated.

[0037] In some possible implementations, the MAC CE further includes carrier configuration information, where the carrier configuration information is used to indicate whether the MAC CE applies to a normal uplink (NUL) carrier configuration or a supplementary uplink (SUL) carrier configuration.

[0038] In some possible implementations, if the field where the carrier configuration information is located is configured as 1, the MAC CE is applied to SUL carrier configuration; otherwise, the MAC CE is applied to NUL carrier configuration.

[0039] In some possible implementations, the MAC CE further includes a serving cell ID, where the serving cell ID is used to indicate a serving cell to which the MAC CE applies.

[0040] In some possible implementations, if the serving cell to which the MAC CE applies is configured as part of a preset component carrier CC list, the MAC CE applies to all CCs in the CC list.

[0041] In some possible implementations, the MAC CE further includes a partial bandwidth identifier BWP ID, where the BWP ID is used to indicate the BWP applied by the MAC CE.

[0042] In some possible implementations, if the MAC CE is applied to a preset component carrier CC list, the BWP ID is ignored.

[0043] In some possible implementations, the MAC CE further includes a reserved bit.

[0044] A third aspect of an embodiment of the present application discloses a resource configuration device, which is applied to a network device.

[0069] Figure 1 It is a schematic diagram of a communication system provided in an embodiment of the present application. Figure 1The communication system in the embodiment may include at least one terminal (e.g., terminal 1, terminal 2) and a network device. The network device is used to provide communication services for the terminal and access the core network. The terminal can access the network by searching for synchronization signals, broadcast signals, etc. sent by the network device, thereby communicating with the network. The terminal can receive configuration information or system information from the network device. It should be understood that the network device included in the communication system may be one or more. A network device can send data or control signaling to one or more terminals. Multiple network devices can also send data or control signaling to one or more terminals at the same time.

[0070] The technical solution provided in this application is introduced in detail below in conjunction with specific implementation methods.

[0071] See also Figure 2 , Figure 2 This is a resource configuration method provided by an embodiment of the present application, which includes but is not limited to the following steps:

[0072] Step 201: A network device sends a media access control element (MAC CE) to a terminal, where the MAC CE is used to configure an association between an aperiodic SRS resource trigger and an aperiodic SRS resource set.

[0073] Step 202: The terminal receives a Media Access Control Element (MAC CE) from the network device.

[0074] Specifically, MAC CE is identified by a MAC subheader with a logical channel identifier (LCID), which has a variable size and has the following fields: activation information (A / D), carrier configuration information (SUL), serving cell ID (Serving Cell ID), bandwidth ID (BWP ID), aperiodic SRS resource trigger ID (aperiodicSRS-ResourceTrigger ID), indication information (T i ), reserved bit (R).

[0075] For example, see also Figure 3 or Figure 4 , Figure 3 and Figure 4 2 are schematic diagrams of the structures of MAC CE provided in the embodiments of the present application. Since an aperiodic SRS resource trigger can be configured to be associated with multiple aperiodic SRS resource sets, the network device can configure multiple aperiodic SRS resource sets and an aperiodic SRS resource trigger through MAC CE, that is, the MAC CE can include multiple aperiodic SRS resource sets and an aperiodic SRS resource trigger, such as Figure 3 or Figure 4As shown; then further indicating which of the multiple aperiodic SRS resource sets the aperiodic SRS resource trigger is associated with in actual applications. At the same time, if it is necessary to change the association between the aperiodic SRS resource trigger and the aperiodic SRS resource set, this can be done by changing the aperiodic SRS resource trigger and / or the aperiodic SRS resource set in the MACCE, and / or changing the association between the aperiodic SRS resource trigger and the aperiodic SRS resource set.

[0076] It can be seen that in this embodiment, the network device sends a MAC CE to the terminal, wherein the MAC CE is used to configure the association between the non-periodic SRS resource trigger and the non-periodic SRS resource set; after receiving the MAC CE, the terminal can learn the association between the non-periodic SRS resource trigger and the non-periodic SRS resource set, and then select the corresponding non-periodic SRS resource set to transmit the SRS according to the non-periodic SRS resource trigger; if the association between the non-periodic SRS resource trigger and the non-periodic SRS resource set needs to be changed, the network device only needs to change the MAC CE to achieve the reconfiguration of the association between the non-periodic SRS resource trigger and the non-periodic SRS resource set without the need for RRC reconfiguration, thereby achieving the association between the non-periodic SRS resource trigger and the non-periodic SRS resource set through MAC configuration, which is conducive to avoiding RRC reconfiguration and reducing system overhead and latency.

[0077] In some possible implementations, the MAC CE includes an aperiodic SRS resource triggering ID, where the aperiodic SRS resource triggering ID is used to indicate an aperiodic SRS resource triggering that the MAC CE needs to configure.

[0078] Please continue reading Figure 3 or Figure 4 , the MAC CE includes an aperiodic SRS resource trigger ID (aperiodicSRS-ResourceTrigger ID), and the aperiodic SRS resource trigger ID is set in the second line of the MAC CE, wherein the aperiodic SRS resource trigger ID is used to indicate the aperiodic SRS resource trigger that the MAC CE needs to configure, for example, this field indicates that the MAC CE is applicable to the code point (Codepoint) of the SRS request field specified in TS 38.212[9].

[0079] It can be seen that in this embodiment, the MAC CE includes a non-periodic SRS resource trigger ID, which is used to indicate the non-periodic SRS resource trigger that the MAC CE needs to configure. Therefore, when the network device configures multiple non-periodic SRS resource triggers, the terminal can determine the non-periodic SRS resource trigger that the MAC CE needs to configure through the non-periodic SRS resource trigger ID.

[0080] In some possible implementations, the MAC CE further includes indication information, where the indication information is used to indicate whether the aperiodic SRS resource set is associated with the aperiodic SRS resource trigger.

[0081] Please continue reading Figure 3 or Figure 4 , MAC CE includes indication information (T i ) indication information is set in the third to Nth lines of the MAC CE, where N is a positive integer; wherein the indication information (T i ) is used to indicate whether the aperiodic SRS resource set is associated with the aperiodic SRS resource trigger. If there is an aperiodic SRS resource set with an aperiodic SRS resource set ID i (srs-ResourceSetId i) specified in TS 38.331[5], then the indication information (T i ) indicates the association status of the aperiodic SRS resource set with the srs-ResourceSetId i, that is, the association status of the aperiodic SRS resource set with the aperiodic SRS resource trigger corresponding to the aperiodic SRS resource trigger ID in the MAC CE. Otherwise, the MAC entity will ignore T i field.

[0082] It can be seen that in this embodiment, MAC CE includes indication information, which is used to indicate whether the non-periodic SRS resource set is associated with the non-periodic SRS resource trigger. Therefore, the terminal can determine whether the non-periodic SRS resource set is associated with the non-periodic SRS resource trigger through the indication information; further, when there are multiple indication information, the terminal can determine which non-periodic SRS resource sets are associated with the non-periodic SRS resource trigger through the indication information, and thus select one or more configurations from these non-periodic SRS resource sets to be associated with the non-periodic SRS resource trigger, thereby realizing the association between the non-periodic SRS resource trigger and the non-periodic SRS resource set through MAC configuration.

[0083] In some possible implementations, if the field where the indication information is located is configured as 1, the aperiodic SRS resource trigger is associated with the aperiodic SRS resource set; otherwise, the aperiodic SRS resource trigger is not associated with the aperiodic SRS resource set.

[0084] Among them, several indication information and a non-periodic SRS resource trigger ID can be set in a MAC CE, and the indication information associated with the non-periodic SRS resource trigger ID is configured by setting the field where each indication information is located, that is, the non-periodic SRS resource set associated with the non-periodic SRS resource trigger is configured by setting the field where each indication information is located.

[0085] Specifically, T i In fact, it is only 1 bit, T i The value is 1, indicating that the aperiodic SRS resource set with the aperiodic SRS resource set ID i is associated with the aperiodic SRS resource trigger corresponding to the aperiodic SRS resource trigger ID in the MAC CE; T i The value is 0, indicating that the aperiodic SRS resource set with the aperiodic SRS resource set ID i is not associated with the aperiodic SRS resource trigger corresponding to the aperiodic SRS resource trigger ID in the MAC CE.

[0086] Please continue reading Figure 3 or Figure 4 , MAC CE includes (N-2)*8 T i , a T i Corresponding to an aperiodic SRS resource set, these T i Set in N-2 rows in the MAC CE, and set 8 T in each row i , 8 T in each row i Respectively represented as T (N-3)*8 、T (N-3)*8+1 、T (N-3)*8+2 、T (N-3)*8+3 、T (N-3)*8+4 、T (N-3)*8+5 、T (N-3)*8+6 、T (N-3)*8+7 , N is the number of rows and N is greater than or equal to 3. Among them, T i The field is set to 1, indicating that the aperiodic SRS resource set corresponding to the field is associated with the aperiodic SRS resource trigger ID corresponding to the aperiodic SRS resource trigger in the MAC CE; i The field is set to 0, indicating that the aperiodic SRS resource set corresponding to the field is not associated with the aperiodic SRS resource trigger corresponding to the aperiodic SRS resource trigger ID in the MAC CE. iThe Ti field is set to 1, indicating that the aperiodic SRS resource set corresponding to srs-ResourceSetId i specified in TS 38.331[5] should be associated with the aperiodicSRS-ResourceTrigger ID in the MAC CE, that is, the aperiodic SRS resource set corresponding to srs-ResourceSetId i specified in TS38.331[5] should be associated with the aperiodicSRS resource trigger corresponding to the aperiodicSRS-ResourceTrigger ID in the MAC CE; the Ti field is set to 0, indicating that the aperiodic SRS resource set corresponding to srs-ResourceSetId i specified in TS38.331[5] should not be associated with the aperiodicSRS-ResourceTrigger ID in the MAC CE, that is, the aperiodic SRS resource set corresponding to srs-ResourceSetId i specified in TS 38.331[5] should not be associated with the aperiodicSRS resource trigger corresponding to the aperiodicSRS-ResourceTrigger ID in the MAC CE.

[0087] For example, the field configuration of the indication information T0, T1, T2, T3, T4, T5, T6, and T7 in the third row of the MAC CE, and the association between the corresponding non-periodic SRS resource sets and the non-periodic SRS resource trigger corresponding to the non-periodic SRS resource trigger ID in the MAC CE are shown in Table 1.

[0088] Table 1 T i Field configuration and non-periodic SRS resource trigger association

[0089] <![CDATA[T i ]]> <![CDATA[T i Field Configuration]]> srs-ResourceSetId i Is it associated with aperiodic SRS resource triggering? <![CDATA[T0]]> 1 0 yes <![CDATA[T1]]> 1 1 yes <![CDATA[T2]]> 1 2 yes <![CDATA[T3]]> 0 3 no <![CDATA[T4]]> 1 4 yes <![CDATA[T5]]> 0 5 no <![CDATA[T6]]> 0 6 no <![CDATA[T7]]> 1 7 yes

[0090] It can be seen from Table 1 that the field configuration of the position of T0, T1, T2, T4, and T7 is 1, which means that the aperiodic SRS resources with aperiodic SRS resource set IDs of 0, 1, 2, 4, and 7 are associated with the aperiodic SRS resource trigger corresponding to the aperiodic SRS resource trigger ID (aperiodicSRS-ResourceTrigger ID) in the MAC CE; the field configuration of the position of T3, T5, and T6 is 0, which means that the aperiodic SRS resources with aperiodic SRS resource set IDs of 3, 5, and 6 are not associated with the aperiodic SRS resource trigger corresponding to the aperiodic SRS resource trigger ID (aperiodicSRS-ResourceTrigger ID) in the MAC CE.

[0091] It can be seen that in this embodiment, a MAC CE may include multiple indication information, that is, there are multiple non-periodic SRS resource sets associated with the non-periodic SRS resource trigger configuration. By configuring the field where each indication information is located to 1 or 0, whether the non-periodic SRS resource set corresponding to each indication information is associated with the non-periodic SRS resource trigger is configured; if the field where the indication information is located is configured to 1, the non-periodic SRS resource trigger is associated with the non-periodic SRS resource set; otherwise, the non-periodic SRS resource trigger is not associated with the non-periodic SRS resource set; thereby, the field where the indication information is located can be changed to change the association relationship between the non-periodic SRS resource trigger and the non-periodic SRS resource set without the need for RRC reconfiguration, which is beneficial to reducing system overhead and latency.

[0092] In some possible implementations, the MAC CE further includes activation information, where the activation information is used to indicate whether to activate the aperiodic SRS resource triggering.

[0093] Please continue reading Figure 3 The activation information (A / D) is set in the first line of the MAC CE. This field indicates whether the indicated aperiodic SRS resource trigger is activated, that is, whether the aperiodic SRS resource trigger corresponding to the aperiodicSRS-ResourceTrigger ID included in the MAC CE is activated. If this field is set to 1, it indicates activation; otherwise, it indicates inactivation.

[0094] It can be seen that in this embodiment, the MAC CE includes activation information for indicating whether to activate the aperiodic SRS resource triggering. After receiving the MAC CE, the terminal determines whether to activate the aperiodic SRS resource triggering according to the activation information.

[0095] In some possible implementations, if the field at the location of the activation information is configured as 1, the aperiodic SRS resource triggering is activated; otherwise, the aperiodic SRS resource triggering is not activated.

[0096] It can be seen that in this embodiment, if the field where the activation information is located is configured as 1, it means that the aperiodic SRS resource trigger is activated; otherwise, it means that the aperiodic SRS resource trigger is not activated.

[0097] In some possible implementations, the MAC CE further includes carrier configuration information, where the carrier configuration information is used to indicate whether the MAC CE applies to a normal uplink (NUL) carrier configuration or a supplementary uplink (SUL) carrier configuration.

[0098] Please continue reading Figure 3 or Figure 4The second line of the MAC CE is provided with a field corresponding to carrier configuration information (SUL), which indicates whether the MAC CE applies to a normal uplink (NUL) carrier configuration or a supplementary uplink (SUL) carrier configuration. If this field is set to 1, it applies to a SUL carrier configuration, and if this field is set to 0, it applies to a NUL carrier configuration.

[0099] It can be seen that in this embodiment, the MAC CE includes carrier configuration information for indicating that the MAC CE is applied to the NUL carrier configuration or the SUL carrier configuration. After receiving the MAC CE, the terminal selects the NUL carrier or the SUL carrier to transmit the SRS according to the indication of the carrier configuration information, so that the network device no longer needs to configure the carrier configuration through other configuration information, thereby further reducing the system overhead.

[0100] In some possible implementations, if the field where the carrier configuration information is located is configured as 1, the MAC CE is applied to SUL carrier configuration; otherwise, the MAC CE is applied to NUL carrier configuration.

[0101] It can be seen that in this embodiment, if the field where the carrier configuration information is located is configured to 1, it means that the MAC CE is applied to the SUL carrier configuration; otherwise, it means that the MAC CE is applied to the NUL carrier configuration; thus, the uplink carrier can be changed by changing the field where the carrier configuration information is located. The network device no longer needs to use other configuration information to change the uplink carrier for transmitting SRS, which is beneficial to reducing system overhead.

[0102] In some possible implementations, the MAC CE further includes a serving cell ID, where the serving cell ID is used to indicate a serving cell to which the MAC CE applies.

[0103] Please continue reading Figure 3 or Figure 4 The first line of the MAC CE is provided with a Serving Cell ID field, which indicates the identity of the serving cell to which the MAC CE applies. The length of this field is 5 bits. If the indicated serving cell is configured as part of the component carrier (CC) list specified in TS 38.331[5], this MAC CE applies to all CCs in the CC list.

[0104] It can be seen that in this embodiment, the MAC CE includes a service cell ID for indicating the service cell to which the MAC CE is applied, that is, by setting the service cell ID in the MAC CE, it is indicated that the association between the non-periodic SRS resource trigger and the non-periodic SRS resource set when the terminal of the service cell corresponding to the service cell ID transmits SRS is the association configured by the MAC CE; thereby, the network device can select the service cell by setting the service cell ID in the MAC CE to configure the association between the non-periodic SRS resource trigger and the non-periodic SRS resource set, and can configure different associations between the non-periodic SRS resource trigger and the non-periodic SRS resource set for different service cells, which is conducive to avoiding resource conflicts.

[0105] In some possible implementations, if the serving cell to which the MAC CE applies is configured as part of a preset component carrier CC list, the MAC CE applies to all CCs in the CC list.

[0106] It can be seen that in this embodiment, if the serving cell to which the MAC CE is applied is configured as part of a preset component carrier CC list, the MAC CE is applied to all CCs in the CC list. That is, since the serving cell to which the MAC CE is applied can utilize all CCs in the CC list, the MAC CE can be applied to all CCs in the CC list.

[0107] In some possible implementations, the MAC CE further includes a bandwidth portion (BWP) identifier BWP ID, where the BWP ID is used to indicate the BWP applied by the MAC CE.

[0108] Please continue reading Figure 3 or Figure 4 , a field corresponding to BWP ID is set in the first line of MAC CE, which indicates the uplink part bandwidth (Uplink BWP, UL BWP) applied by MAC CE as the code point of the DCI bandwidth part indicator field specified in TS 38.212[9]; the length of the BWP ID field is 2 bits; if this MAC CE is applied to the CC list, this field will be ignored.

[0109] It can be seen that in this embodiment, the MAC CE includes a BWP identifier BWPID for indicating the MAC CE application, so that it can be determined that the terminal transmits the SRS through the BWP corresponding to the BWP ID. The network device does not need to indicate through other configuration information, which is conducive to reducing system overhead.

[0110] In some possible implementations, if the MAC CE is applied to a preset component carrier CC list, the BWP ID is ignored.

[0111] It can be seen that in this embodiment, if the MAC CE is applied to the preset component carrier CC list, that is, the component carrier for transmitting the SRS has been determined, the BWP ID in the MAC CE is ignored.

[0112] In some possible implementations, the MAC CE further includes a reserved bit.

[0113] The reserved bit field in the MAC CE is set to 0.

[0114] Please continue reading Figure 3 or Figure 4 ,exist Figure 3 and Figure 4 The second row in the MAC CE structure shown is set with 3 reserved bits R; Figure 3 and Figure 4 The difference is that Figure 3 The first row in the MAC CE structure shown is provided with activation information (A / D), and Figure 4 The corresponding position in the first row of the MAC CE structure shown is set to the reserved bit R.

[0115] It can be seen that in this embodiment, the MAC CE includes a reserved bit. When the network device needs to configure other information, it can be configured through the reserved bit without the need to configure through other configuration information, which is conducive to reducing system overhead.
