[0088] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the embodiments of the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the embodiments of the present disclosure as detailed in the appended claims.

[0089] The terms used in the disclosed embodiments are only for the purpose of describing specific embodiments and are not intended to limit the disclosed embodiments. The singular forms of "a", "an" and "the" used in the disclosed embodiments and the appended claims are also intended to include plural forms unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0090] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present disclosure, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information.

[0091] The temporary reference signal transmission method, device and storage medium provided by the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0092] Figure 1aA flow chart of a temporary reference signal receiving method provided in an embodiment of the present disclosure, the method is executed by a UE, such as Figure 1a As shown, the method may include the following steps:

[0093] Step 101: A UE receives a MAC CE signaling sent by a base station, where the MAC CE signaling includes a first indication field.

[0094] In one embodiment of the present disclosure, the first indication field in the MAC CE signaling corresponds to the secondary cell to be activated, and the first indication field is used to trigger the transmission of a temporary reference signal of the corresponding secondary cell to be activated.

[0095] Furthermore, in one embodiment of the present disclosure, the MAC CE signaling may further include a second indication field, wherein the second indication field may be, for example, a C field, and a second indication field may correspond to a secondary cell and be used to indicate the activation status of the corresponding secondary cell.

[0096] Specifically, in one embodiment of the present disclosure, the second indication field may carry the number Ci of the corresponding ith secondary cell and the value of Ci, wherein the value of Ci is used to indicate the activation state of the ith secondary cell. For example, in one embodiment of the present disclosure, when Ci=1, the activation state of the ith secondary cell is indicated as: activated; when Ci=0, the activation state of the ith secondary cell is indicated as: deactivated. Thus, the UE can determine the activation state of each secondary cell based on the second indication field in the MAC CE signaling.

[0097] Further, it should be noted that, in an embodiment of the present disclosure, the second indication field also corresponds to the first indication field, wherein the second indication field corresponding to the first indication field may specifically include: the first indication field only corresponds to the second indication field of the secondary cell to be activated.

[0098] For example, Figure 1b A schematic diagram of the structure of a MAC CE signaling provided in an embodiment of the present disclosure, such as Figure 1b As shown, the MAC CE signaling includes a first indication field (for example, the length may be 4 bits) and a second indication field. Figure 1b It can be seen that the second indication field indicates the number C5, C 16 , C 17 and C 31The secondary cell of the activated state enters the activated state, thereby determining that the secondary cell #5, the secondary cell #16, the secondary cell #17 and the secondary cell #31 are cells to be activated, and the number of cells to be activated is 4. Based on this, since the first indication domain corresponds to the cell to be activated, the number of the first indication domain should also be 4, namely the first indication domain T1, the first indication domain T2, the first indication domain T3 and the first indication domain T4. Among them, reference Figure 1b It can be seen that the correspondence between the first indication field and the secondary cell to be activated is shown in Table 1.

[0099] Table 1

[0100] Secondary cell number First indicator field #5 T1 #16 T2 #17 T3 #31 T4

[0101] It can be seen from Table 1 that the first indication domain T1 corresponds to the secondary cell to be activated #5, and is used to trigger the transmission of the temporary reference signal of the secondary cell to be activated #5; the second indication domain T2 corresponds to the secondary cell to be activated #16, and is used to trigger the transmission of the temporary reference signal of the secondary cell to be activated #16; the third indication domain T3 corresponds to the secondary cell to be activated #17, and is used to trigger the transmission of the temporary reference signal of the secondary cell to be activated #17; the fourth indication domain T4 corresponds to the secondary cell to be activated #31, and is used to trigger the transmission of the temporary reference signal of the secondary cell to be activated #31.

[0102] In addition, in another embodiment of the present disclosure, the first indication field and the second indication field may also be included by different MACCE signaling. For example, Figure 1c A schematic diagram of another structure of MAC CE signaling provided in an embodiment of the present disclosure, such as Figure 1c As shown, the first MAC CE signaling includes a first indication field, the second MAC CE signaling includes a second indication field, and the first indication field corresponds to the second indication field of the secondary cell to be activated.

[0103] Further, it should be noted that, in one embodiment of the present disclosure, the first indication field may also correspond only to the secondary cell activated for the first time, and need not correspond to all the secondary cells to be activated, thereby greatly saving signaling overhead. Moreover, for the secondary cell not activated for the first time, when it is activated for the second time and thereafter, the transmission of the temporary reference signal may be directly triggered without the indication of the first indication field.

[0104] For example, Figure 1d A schematic diagram of another structure of MAC CE signaling provided in an embodiment of the present disclosure, such as Figure 1dAs shown, the first indication field and the second indication field are included in the same MAC CE signaling, and the second indication field indicates that the secondary cells to be activated are secondary cells #5, secondary cells #16, secondary cells #17 and secondary cells #31, among which only secondary cells #16 and secondary cells #17 are secondary cells activated for the first time, and the first indication field only corresponds to the secondary cells #16 and secondary cells #17 activated for the first time. Figure 1d The table shows the correspondence between the first indication field in the MAC CE signaling and the secondary cell to be activated.

[0105] Table 2

[0106] It can be seen from Table 2 that the first indication field T1 corresponds to the secondary cell to be activated #17, and is used to trigger the transmission of the temporary reference signal of the secondary cell to be activated #17; the second indication field T2 corresponds to the secondary cell to be activated #16, and is used to trigger the transmission of the temporary reference signal of the secondary cell to be activated #16.

[0107] Further, Figure 1e A schematic diagram of another structure of MAC CE signaling provided in an embodiment of the present disclosure, such as Figure 1e As shown, the first indication field and the second indication field are included by different MAC CE signaling, wherein the first MAC CE signaling includes the first indication field, the second MAC CE signaling includes the second indication field, and the second indication field indicates that the secondary cells to be activated are secondary cell #5, secondary cell #16, secondary cell #17 and secondary cell #31, wherein only secondary cell #16 and secondary cell #17 are secondary cells activated for the first time, and the first indication field only corresponds to the secondary cell #16 and secondary cell #17 activated for the first time.

[0108] In addition, it should be noted that in one embodiment of the present disclosure, since the number of cells to be activated each time may be different, the number of first indication fields included in the MAC CE signaling will also be different, that is, the MAC CE signaling sent each time is variable in length. Based on this, in one embodiment of the present disclosure, the length of the PDU of the MAC CE signaling can also be additionally indicated. For example, in one embodiment of the present disclosure, the length of the PDU (Packet Data Unit) of the MAC CE signaling can be indicated by the L field, for example.

[0109] Finally, optionally, in an embodiment of the present disclosure, the first indication field may carry temporary reference signal triggering information, and the temporary reference signal triggering information may be used to trigger the transmission of a temporary reference signal of the corresponding cell to be activated.

[0110] Step 102: The UE determines a secondary cell to be activated.

[0111] In one embodiment of the present disclosure, the method for the UE to determine the secondary cell to be activated may be: the UE determines the secondary cell to be activated based on the value of Ci carried by the second indication field.

[0112] Step 103: The UE receives a temporary reference signal in the secondary cell to be activated.

[0113] Optionally, in an embodiment of the present disclosure, the UE may specifically receive the temporary reference signal based on the temporary reference signal triggering information carried in the first indication field corresponding to the cell to be activated.

[0114] In summary, in the temporary reference signal transmission method proposed in the present disclosure, the UE will receive the MACCE signaling sent by the base station, wherein the MAC CE signaling includes a first indication field, and the first indication field corresponds to the secondary cell to be activated. After that, the UE will determine the secondary cell to be activated, and will receive the temporary reference signal in the secondary cell to be activated. It can be seen that in the embodiment of the present disclosure, the MAC CE signaling is mainly used to trigger the transmission of the temporary reference signal of the secondary cell to be activated, that is, the MAC CE signaling is mainly used to indicate the transmission status of the temporary reference signal of the secondary cell to be activated, without indicating the transmission status of the reference signals of all secondary cells, thereby saving the overhead of MAC CE signaling, reducing the signaling cost, and saving resources. Moreover, in the embodiment of the present disclosure, the transmission status of the temporary reference signal of different secondary cells to be activated can be indicated by MAC CE signaling each time, which has high flexibility.

[0115] Figure 2 A flow chart of a temporary reference signal receiving method provided in an embodiment of the present disclosure, the method is executed by a UE, such as Figure 2 As shown, the method may include the following steps:

[0116] Step 201: The UE receives the indication information sent by the base station, where the indication information includes the first indication field in the MAC CE signaling and the auxiliary

[0117] Secondary cell number First indicator field #17 T1 #16 T2

[0118] The correspondence between the cells.

[0119] Among them, the relevant introduction about MAC CE signaling, the first indication field, and the second indication field included in the MAC CE signaling can be referred to the description of the above embodiment, and the embodiment of the present disclosure will not be repeated here.

[0120] Step 202: The UE determines a secondary cell to be activated according to the indication information.

[0121] In one embodiment of the present disclosure, the indication information may further include a subset selection field, and the subset selection field is used to indicate the temporary reference signal subset corresponding to the first indication field. Among them, in one embodiment of the present disclosure, the configuration information of the above-mentioned temporary reference signal subset may be: N groups of temporary reference signal configuration information among all M groups of temporary reference signal configuration information of the secondary cell to be activated. In one embodiment of the present disclosure, the M groups of temporary reference signal configuration information may be configured to the UE by the base station through RRC (Radio Resource Control) signaling, M, N are positive integers, N≤M. Among them, the temporary reference signal configuration information may include at least one of the time-frequency resources of the temporary reference signal, the number of bursts of the temporary reference signal, and the transmission timing of the temporary reference signal. Therefore, the UE can receive the temporary reference signal in the corresponding cell to be activated based on the temporary reference signal configuration information subset.

[0122] Specifically, in one embodiment of the present disclosure, the subset selection field carries a number of bits, wherein there is a corresponding relationship between the number of bits carried by the subset selection field and the temporary reference signal subset, and different numbers of bits correspond to different temporary reference signal subsets. Based on this, when the UE obtains the indication information, it can determine the temporary reference signal subset corresponding to the first indication field based on the corresponding relationship and the number of bits on the subset selection field of the indication information.

[0123] For example, in an embodiment of the present disclosure, the length of the subset selection field may be 1 bit. And, Table 3 is a correspondence between a subset selection field and a temporary reference signal subset provided in an embodiment of the present disclosure.

[0124] Table 3

[0125] Number of bits carried by the subset selection field Temporary Reference Signal Subset 0 Indicates the temporary reference signal configuration information numbered 0 to 15 1 Indicates the temporary reference signal configuration information numbered 16 to 31

[0126] As shown in Table 3, when the number of bits carried by the subset selection domain is 0, the temporary reference signal subset corresponding to the first indication domain is: the temporary reference signal configuration information numbered 0 to 15 among all M groups of temporary reference signal configuration information of the secondary cell to be activated corresponding to the first indication domain; when the number of bits carried by the subset selection domain is 1, the temporary reference signal subset corresponding to the first indication domain is: the temporary reference signal configuration information numbered 16 to 31 among all M groups of temporary reference signal configuration information of the secondary cell to be activated corresponding to the first indication domain.

[0127] And, it should be noted that, in one embodiment of the present disclosure, the correspondence between the number of bits carried by the above-mentioned subset selection field and the temporary reference signal subset can be predefined by a protocol. In another embodiment of the present disclosure, the correspondence between the above-mentioned subset selection field and the temporary reference signal subset can be configured by the base station to the UE through RRC signaling.

[0128] Further, it should be noted that in one embodiment of the present disclosure, the number of subset selection fields in the indication information may be only one. At this time, the subset selection field is used to indicate the temporary reference signal subset corresponding to all first indication fields in the MAC CE signaling, that is, assuming that when the number of bits carried by the subset selection field is 0, the temporary reference signal subsets of all first indication fields are: the temporary reference signal configuration information numbered 16 to 31 in all M groups of temporary reference signal configuration information of the corresponding secondary cell to be activated

[0129] In another embodiment of the present disclosure, the number of the subset selection fields may correspond one-to-one to the first indication field. In this case, each subset selection field is only used to indicate a temporary reference signal subset of the corresponding first indication field.

[0130] And, in one embodiment of the present disclosure, when the UE determines the temporary reference signal subset corresponding to each first indication field, it can subsequently receive the temporary reference signal in the corresponding cell to be activated based on the temporary reference signal subset.

[0131] In addition, in one embodiment of the present disclosure, the manner in which the base station sends the indication information to the UE may be: explicit sending.

[0132] Among them, in one embodiment of the present disclosure, the method of sending indication information to the UE in an explicit sending manner may include at least one of the following:

[0133] Method 1: sending the indication information to the UE through downlink control information (DCI) signaling, wherein the indication information can be carried in an existing information field of the DCI signaling, and the DCI signaling is a DCI signaling for scheduling a PDSCH (Physical Downlink Shared Channel) carrying MAC CE signaling;

[0134] Method 2: sending the indication information to the UE through the coded information of the DCI signaling, wherein the coded information may be frozen bits in the coded bits of the DCI signaling; the DCI signaling is the DCI signaling used for scheduling the PDSCH carrying the MAC CE signaling;

[0135] Method 3: Send via MAC CE signaling.

[0136] Furthermore, in another embodiment of the present disclosure, the manner in which the base station sends the indication information to the UE may be: implicit sending.

[0137] Among them, in one embodiment of the present disclosure, the method of sending indication information to the UE in an implicit sending manner may include:

[0138] The control resource set (CORSET) identifier (ID, also known as number), search space identifier (searchspaceID), or cell identifier (cellID) of the PDCCH (Physical Downlink Control Channel) is sent to the UE through DCI signaling. The CORSET ID, searchspace ID, and cell ID are used to indicate the above indication information; and the PDCCH can specifically be a PDCCH used to send MAC CE signaling.

[0139] And, it should be noted that, in an embodiment of the present disclosure, when the above-mentioned CORSET ID, or search space ID, or cell ID is sent through DCI signaling, it can be specifically sent through a new information field in the DCI signaling that is different from the existing information field.

[0140] Step 203: The UE receives a temporary reference signal in the secondary cell to be activated.

[0141] Optionally, in an embodiment of the present disclosure, the first indication field in the MAC CE signaling may carry temporary reference signal triggering information, and the UE may trigger the secondary cell to be activated based on the temporary reference signal triggering information carried in the first indication field.

[0142] In summary, in the temporary reference signal transmission method proposed in the present disclosure, the UE will receive the MACCE signaling sent by the base station, wherein the MAC CE signaling includes a first indication field, and the first indication field corresponds to the secondary cell to be activated. After that, the UE will determine the secondary cell to be activated, and will receive the temporary reference signal in the secondary cell to be activated. It can be seen that in the embodiment of the present disclosure, the MAC CE signaling is mainly used to trigger the transmission of the temporary reference signal of the secondary cell to be activated, that is, the MAC CE signaling is mainly used to indicate the transmission status of the temporary reference signal of the secondary cell to be activated, without indicating the transmission status of the reference signals of all secondary cells, thereby saving the overhead of the MAC CE signaling and reducing the signaling cost.

[0143] Figure 3 A flow chart of a temporary reference signal sending method provided in an embodiment of the present disclosure, the method is executed by a base station, such as Figure 3 As shown, the method may include the following steps:

[0144] Step 301: The base station sends a MAC CE signaling, where the MAC CE signaling includes a first indication field, and the first indication field corresponds to a secondary cell to be activated.

[0145] In one embodiment of the present disclosure, the MAC CE signaling may further include a second indication field, and the second indication field corresponds to the first indication field.

[0146] Step 302: The base station sends a temporary reference signal in the determined secondary cell to be activated.

[0147] Among them, the relevant introduction about the MAC CE signaling, the first indication field, the secondary cell to be activated, and the second indication field in steps 301-302 can be referred to the above embodiments, and the embodiments of the present disclosure will not be elaborated here.
