[0038] As described above, in the current NR R17, the downlink common beam indication and the uplink common beam indication are being discussed. Among them, it is clearly supported to indicate the downlink common beam through the downlink control information, and for the uplink common beam indication, there is currently no specific indication scheme yet.

[0039] In the embodiment of the present invention, by setting the field for indicating the common beam and the MAC CE information configured by the network side, the downlink common beam and / or the uplink common beam can be determined, and the MAC CE can be used to indicate the downlink common beam information and / or the uplink common beam information, filling the gap in the prior art.

[0040] To make the above objects, features, and beneficial effects of the present invention more obvious and understandable, the following will specifically describe the embodiments of the present invention in conjunction with the accompanying drawings.

[0041] Refer to Figure 1 , Figure 1 is a flowchart of a method for identifying a common beam in an embodiment of the present invention. The method for identifying the common beam may include steps S11 to S12:

[0042] Step S11: Receive a DCI instruction, where the DCI instruction contains a field for indicating the common beam;

[0043] Step S12: Determine the downlink common beam and / or the uplink common beam according to the field for indicating the common beam and the MAC CE information configured by the network side.

[0044] In the specific implementation of step S11, the field for indicating the common beam can be obtained by receiving a downlink control information (DCI) instruction.

[0045] Furthermore, the field can be used to indicate that the UE adopts the MAC CE information configured by the network side.

[0046] Furthermore, the field can have codepoint index information. Specifically, the codepoint index information of the DCI transmission configuration indication field specified in the communication protocol (such as TS 38.212) can be reused, and the codepoint index information of other appropriate fields can also be adopted.

[0047] In the specific implementation of step S12, the UE may determine the downlink common beam and / or the uplink common beam according to the field indicating the common beam and the Media Access Control Control Element (MAC CE) information configured by the network side.

[0048] Further, the step of determining the downlink common beam and / or the uplink common beam according to the field indicating the common beam and the MAC CE information may include: determining the activation indication information of the common beam pair according to the code point index information of the field indicating the common beam and the MAC CE information; determining whether the common beam in the common beam pair is activated according to the activation indication information of each common beam pair; wherein each common beam pair includes a downlink common beam and / or an uplink common beam, and the downlink common beam and the uplink common beam have their respective activation indication information.

[0049] Specifically, it may be set that when the activation indication information is a preset value, it indicates that the common beam in the common beam pair is activated, and the preset value is 1 or 0.

[0050] More specifically, it may be set that when the activation indication information is 1, it indicates that the common beam in the common beam pair is activated, or it may be set that when the activation indication information is 0, it indicates that the common beam in the common beam pair is activated.

[0051] In the embodiment of the present invention, by setting the activation indication information of the common beam pair determined according to the code point index information and the MAC CE information, it can be determined whether the common beam in the common beam pair is activated, so that the MAC CE can effectively indicate the downlink common beam information and / or the uplink common beam information.

[0052] Refer to Figure 2 , Figure 2 which is a schematic diagram of the frame structure of a MAC CE in the embodiment of the present invention.

[0053] As shown in the figure, the MAC CE may include a sub-header identifier of the protocol data unit (MAC PDU) of the logical channel identity (eLCID). It may include the following fields:

[0054] Service cell ID: It may be used to indicate the identity of the service cell applicable to the MAC CE, and the length of its field may be 5 bits;

[0055] Bandwidth Part (BWP) ID: It can be used to indicate a DownLink (DL) BWP and / or its associated UpLink (UL) BWP, and the MAC CE is applied to this DL BWP and / or its associated UL BWP. For example, it can be the code point of the DCI bandwidth part indicator field specified in TS 38.212. The length of the BWP ID field can be 2 bits.

[0056] Reserved bit R, for example, can be set to "0".

[0057] Furthermore, the MAC CE may further include a C i field and / or a T i field. The C i field is used to indicate the activation indication information of the downlink common beam in the (i + 1)-th common beam pair, and the T i field is used to indicate the activation indication information of the uplink common beam in the (i + 1)-th common beam pair.

[0058] Specifically, the C i field can indicate whether the first TCI state ID (TCI state ID i,1 ) is valid / activated. If the C i field is set to "1", then the TCI state ID i,1 is valid / activated. If this C i field is set to "0", then the TCI state ID i,1 is invalid / unactivated;

[0059] The T i field can indicate whether the second TCI state ID (TCI state ID i,2 ) is valid / activated. If this T i field is set to "1", then the TCI state ID i,2 is valid / activated. If this T i field is set to "0", then the TCI state ID i,2 is invalid / unactivated.

[0060] It should be noted that C i and T i should not be set to "0" simultaneously.

[0061] In the embodiments of the present invention, by setting the MAC CE to include a C i field and / or a T i field, the C iThe field is used to indicate the activation indication information of the downlink common beam in the (i + 1)-th common beam pair, where T i The field is used to indicate the activation indication information of the uplink common beam in the (i + 1)-th common beam pair, which can effectively implement the MAC CE to indicate the activation indication information.

[0062] Furthermore, the MAC CE may further include a TCI state ID i,j (TCI state ID i,j ) field, and each TCI state ID i,j field is used to indicate the j-th common beam in the (i + 1)-th common beam pair; where i is a non-negative integer and j is a positive integer.

[0063] Specifically, this field may indicate the TCI state identified by the TCI state ID specified in the communication protocol, for example, it may be specified by TS 38.331.

[0064] Where i may be the code point index of the DCI transmission configuration indication field (DCI Transmission configuration indication field) specified in the communication protocol. For example, it may be specified by TS 38.212.

[0065] TCI state ID i,j may represent the j-th TCI state indicated by the (i + 1)-th code point in the DCI transmission configuration indication field. The TCI code point mapped by the TCI state may be determined by its sequential position among all TCI code points with TCI state ID i,j fields, that is, the first TCI state ID 0,1 and TCI state ID 0,2 (i.e., the first common beam pair) is mapped to the TCI code point value (codepoint value) of 0, and the second TCI state ID 1,1 and TCI state ID 1,2 (i.e., the second common beam pair) is mapped to the TCI code point value of 1, and so on.

[0066] Furthermore, N is used to represent the maximum number of common beam pairs, and the maximum can be set to 8 (equivalent to the maximum value of i being 7), and the maximum value of j can be 2.

[0067] Specifically, the maximum number of activated TCI code points may be 8, and the maximum number of TCI states mapped to each TCI code point may be 2.

[0068] Further, the step of determining the activation indication information of the common beam pair according to the code point index information of the field indicating the common beam and the MAC CE information may include: using the code point index information as i to determine the TCI state ID in the MAC CE i,j field and the downlink common beam and / or uplink common beam indicated thereby; determining the activation indication information of each of the downlink common beam and / or uplink common beam.

[0069] It should be noted that, in another specific implementation manner of the embodiment of the present invention, the TCI state ID i,j may also be used to indicate downlink common QCL-TypeA information, and / or QCL-TypeB information, and / or QCL-TypeC information, and / or QCL-TypeE information; the TCI state ID i,j may also be used to indicate uplink common path loss reference signal information, and / or uplink common power control information.

[0070] Among them, Quasi co-location (QCL)-TypeA may include but is not limited to Doppler shift, Doppler spread, average delay, and delay spread; QCL-TypeB may include but is not limited to Doppler shift, Doppler spread; QCL-TypeC may include but is not limited to Doppler shift, average delay. In the embodiment of the present invention, the MAC CE is set to include the TCI state ID i,j field, and using the code point index information as i to determine the TCI state ID i,j field and the downlink common beam and / or uplink common beam indicated thereby can effectively implement the MAC CE to indicate the downlink common beam information and / or the uplink common beam information.

[0071] Further, the MAC CE may include all TCI state ID i,j fields; wherein, the activation indication information corresponding to each TCI state ID i,j field is adjacent to the TCI state ID i,j field.

[0072] Specifically, in Figure 2 a specific implementation manner shown, the MAC CE may be set to include all TCI state ID i,j fields, and the activation indication information corresponding to each TCI state ID i,j field is adjacent to the TCI state ID i,jThe fields are adjacent, so that the activation indication information and the TCI status ID i,j field can achieve a one-to-one correspondence relationship, and more intuitively indicate each common beam and whether it is activated.

[0073] Refer to Figure 3 , Figure 3 which is a schematic diagram of the frame structure of another MAC CE in an embodiment of the present invention.

[0074] In Figure 3 another specific embodiment shown, the MAC CE may only include the TCI status ID with the activation indication information being a preset value i,j field, where the preset value is 1 or 0; wherein, the fields of each activation indication information are arranged in sequence.

[0075] Specifically, the fields C i of each activation indication information are arranged in sequence, and the fields T i of each activation indication information are arranged in sequence.

[0076] In another specific embodiment of the embodiment of the present invention, it may be set that the MAC CE only includes the TCI status ID with the activation indication information being a preset value i,j field, and the fields of each activation indication information are arranged in sequence, so that it can be realized that only a part of the TCI status ID i,j field can enable the UE to determine the activation situation of all common beams, effectively reducing the MAC CE signaling overhead.

[0077] In the embodiment of the present invention, by setting the field indicating the common beam and the MAC CE information configured by the network side, the downlink common beam and / or the uplink common beam can be determined, and the MAC CE can be used to indicate the downlink common beam information and / or the uplink common beam information, filling the gap in the prior art.

[0078] Refer to Figure 4 , Figure 4 which is a flowchart of another method for identifying a common beam in an embodiment of the present invention. The another method for identifying a common beam may include steps S41 to S42:

[0079] Step S41: Configure the MAC CE information;

[0080] Step S42: Send a DCI instruction, where the DCI instruction contains a field for indicating a common beam, so that the UE determines the downlink common beam and / or the uplink common beam according to the field indicating the common beam and the MAC CE information.

[0081] In the specific implementation of step S41, the network side can configure the MAC CE information.

[0082] Among them, the MAC CE information can refer to Figure 2 and Figure 3 the descriptions in, and can be configured in a conventional and appropriate manner.

[0083] In the embodiments of the present invention, the MAC CE information can be transmitted in a conventional and appropriate transmission manner, and the specific transmission manner of the MAC CE information is not limited.

[0084] In the specific implementation of step S42, the step of sending the DCI instruction may include: sending the DCI instruction so that the UE determines the activation indication information of the common beam pair according to the code point index information of the field indicating the common beam and the MAC CE information, and determines whether the common beam in the common beam pair is activated according to the activation indication information of each common beam pair; where each common beam pair includes a downlink common beam and / or an uplink common beam, and the downlink common beam and the uplink common beam have their respective activation indication information.

[0085] Further, the MAC CE may include a C i field and / or a T i field. The C i field is used to indicate the activation indication information of the downlink common beam in the (i + 1)-th common beam pair, and the T i field is used to indicate the activation indication information of the uplink common beam in the (i + 1)-th common beam pair; where i is a non-negative integer.

[0086] Further, the MAC CE may include a TCI state ID i,j field. Each TCI state ID i,j field is used to indicate the j-th common beam in the (i + 1)-th common beam pair; where i is a non-negative integer and j is a positive integer.

[0087] Further, the code point index information can be used as i so that the UE determines the TCI state ID i,j field and the downlink common beam and / or uplink common beam indicated by it in the MAC CE, and further determines the respective activation indication information of the downlink common beam and / or uplink common beam.
