As shown in fig. 2, a flowchart of a method 200 for determining a target time domain location provided in an exemplary embodiment of the present application is illustrated, and the method 200 may be applied to, but is not limited to, a communication device, and may specifically be implemented by software and/or hardware installed in the communication device. Optionally, the communication device may be a terminal, or may be a network side device, such as a base station. The method 200 for determining the temporal location of the target may comprise at least the following steps.

S210, under the condition that a plurality of different SSBs are multiplexed with a Type 0PDCCH and the SCS of the SSBs is not larger than the SCS of the Type 0PDCCH, determining target time domain position information according to a target frame structure.

The multiplexing mode for multiplexing the SSB and the Type 0PDCCH (i.e., coreset 0) may be Pattern2 and/or Pattern3.

Specifically, in the 5G NR system, each radio frame with a time domain length of 10ms is divided into 10 subframes with the same size and length of 1ms, each subframe may include a plurality of slots due to different SCS, each slot is composed of a certain number of symbols (Symbol), and the number of symbols is determined by Cyclic Prefix (CP) type. In addition, the NR system supports multi-beam synchronization signal, secondary synchronization signal and physical broadcast channel transmission, wherein the number of candidate SSBs and the first symbol index position for a half frame (5 ms) with SSBs can be determined according to SCS of the SSBs. For example, the following Case d, case E are for half frames.

CaseD-120KHz SCS: the index of the first symbol of the candidate SSB is {4,8, 16, 20} +28 × n, for F >6ghz, n =0,1,2,3,5,6,7,8, 10, 11, 12, 13, 15, 16, 17, 18 (8 slots in 1ms, 2 SSBs in 1 slot, 1ms occupies 16 SSBs, 4 groups in total, then Lmax =64 in 4 ms), where Lmax denotes the total number of beams (beam) corresponding to the SSBs.

CaseE-240KHz SCS: the index of the first symbol of the candidate SSB is {8, 12, 16, 20, 32, 36, 40, 44} +56 × n, for F >6ghz, n =0,1,2,3,5,6,7,8 (16 slots in 1ms, 2 SSBs in 1 slot, 32 SSBs in 1ms, 2 groups total, and Lmax =64 in 2 ms), where Lmax denotes the total number of beams (beam) to which the SSB corresponds.

In addition, because the internal structure of the SSB is standardized by the communication protocol, when the communication device searches for the SSB at a specific synchronization frequency point, it can attempt to decode the SSB. The important Information contained in the SSB is a Master Information Block (MIB), and the MIB carries related configuration Information of a PDCCH for scheduling a Remaining Minimum Information Block (Remaining Minimum SI, RMSI), so as to help a user confirm resource configuration of the RMSI PDCCH and a time for monitoring the PDCCH, where, as shown in fig. 3a, 3b, and 3c, three relative relationships exist between the RMSI core and the SSB where the PDCCH is located:

pattern1: SSB and its corresponding RMSI core TDM (time division multiplexing);

pattern2: SSB and its corresponding RMSI CORESET FDM (frequency division multiplexing);

pattern3: SSB and RMSI CORESET FDM corresponding thereto.

In this step, the multiplexing mode for multiplexing the plurality of different SSBs and the Type 0PDCCH may be Pattern2 and/or Pattern3.

The target time domain location information is time domain location information (such as an index of a time slot, an index of a system frame, and the like) where the Type 0PDCCH corresponding to the target SSB is located, and is used for monitoring the Type 0PDCCH corresponding to the target SSB at a time domain location corresponding to the target time domain location information. The target SSB may be any one of multiple SSBs sent by the network side device and received by the communication device.

Optionally, when determining the target time domain location information, the target frame structure may be a preset frame structure, or a frame structure determined based on the SCS of the Type 0PDCCH, or a frame structure determined based on the SCS of the SSB, and the like, which is not limited herein.

In the method 200 for determining the target time domain location in this embodiment, when a plurality of different SSBs are multiplexed with the Type 0PDCCH, and the SCS of the SSBs is not greater than the SCS of the Type 0PDCCH, the communication device determines, based on the target frame structure, the time domain location information where the Type 0PDCCH corresponding to the target SSB is located, so that the time domain location information where the Type 0PDCCH corresponding to the target SSB is located can be accurately located to monitor the Type0 PDCCH.

(1) A predetermined value. In one implementation, the predetermined value may be 0,1,2, etc.

(2) The method is obtained through network side equipment configuration.

(3) And determining the target SSB according to the index of the target SSB. In an implementation manner, different preset offset values may be preconfigured according to an index of the SSB, so as to determine a time domain position of the Type 0PDCCH actually mapped by the SSB according to the preset offset value.

In one implementation, the communication device may monitor the Type 0PDCCH corresponding to the target SSB at the time domain position corresponding to the candidate time domain position information and the time domain position after the offset, so as to further improve the monitoring accuracy.

In the method 400 for determining a target time domain position in the present embodiment, when a plurality of different SSBs are multiplexed with a Type 0PDCCH, and an SCS of the SSBs is not greater than an SCS of the Type 0PDCCH, candidate time domain position information where the Type 0PDCCH corresponding to the target SSB is located is determined based on a target frame structure, and a preset offset value is offset on the basis of a time domain position corresponding to the candidate time domain position information, so as to monitor the Type 0PDCCH corresponding to the SSB at the offset time domain position, thereby further accurately positioning the time domain position information where the Type 0PDCCH corresponding to the SSB is located, and implementing monitoring of the Type0 PDCCH.

As shown in fig. 5, a flowchart of a method 500 for determining a target time domain position provided in an exemplary embodiment of the present application is illustrated, and the method 500 may be applied to, but is not limited to, a communication device, and may be specifically implemented by software and/or hardware installed in the communication device.
