Three types of multiplexing of SS/PBCH block supported by the NR system and QCLed system information block 1 (system information block 1, SIB1)/remaining minimum system information (RMSI), refer to Figure 2 , Respectively, pattern1, pattern2, and pattern3. For pattern1, SS/PBCH block and CORESET#0 (or Type0-PDCCH)/PDSCH exist in the form of time division multiplexing, which is mainly used in FR1; in pattern2, SS/PBCH block and The PDSCHs of QCLed exist in the form of frequency division multiplexing; in pattern 3, the SS/PBCH block and the CORESET#0 (or Type0-PDCCH)/PDSCH of QCLed exist in the form of frequency division multiplexing. Pattern2 and pattern3 are mainly used for FR2 and higher frequency bands (including shared frequency bands working at 60GHz). The embodiments of this application mainly discuss the configuration of frequency domain resources under pattern2 and/or pattern3.

With reference to the network framework diagram of FIG. 1, a resource configuration method in an embodiment of the present application includes steps 301 to 303:

301. The network device determines a frequency domain resource used to send a broadcast signal, where the frequency domain resource occupies a ratio of system bandwidth greater than or equal to a preset ratio, and the system bandwidth represents the bandwidth used by the network device and terminal device for communication;

In the shared access system of high frequency band (such as 60GHz), the communication between network equipment and terminal equipment needs to meet the occupied channel bandwidth (OCB) requirements, that is, in the communication between network equipment and terminal equipment, the corresponding channel must meet a lot of requirements The bandwidth of the preset ratio is occupied, and the preset ratio is generally 70%.

In the embodiment of the present application, a resource block (resource block, RB) occupied by frequency domain resources for transmitting broadcast signals is called an occupied resource block. The resource block may also be defined as a physical resource block (Physical Resource Block, PRB).

The broadcast signal includes system information and synchronization signal block (SS/PBCH block). The system information is indicated by type 0 control resource set (control resource set 0, CORESET#0 or CORESET0), and CORESET#0 is indicated by Type 0 PDCCH transmission.

The resource block occupied by CORESET#0 can be continuous or discontinuous. In this embodiment, the resource block occupied by CORESET#0 is referred to as the CORESET#0 resource block. When the resource block occupied by CORESET#0 is not continuous, CORESET#0 is divided into multiple CORESET#0 sub-blocks, and the content contained in the multiple CORESET#0 sub-blocks may be the same or different. In the embodiment of the present application, the CORESET#0 sub-block may also be a CORESET#0 subset. In this embodiment, only the CORESET#0 sub-block is used as an example for description. Referring to Fig. 4, CORESET#0 includes multiple CORESET#0 sub-blocks 401 to 403, and the interval between adjacent CORESET#0 sub-blocks is CORESET#0 interval 404. To 405.

Type 0 The offset (offset) between the start position of the PDCCH and the start position of the SS/PBCH block is the first offset, and the occupied resource block is the offset resource block.

Taking the multiplexing condition based on pattern3 as an example, refer to Figure 5.1. When the value of CORESET#0 and the value of the first offset are positive, the frequency domain position of Type 0 PDCCH is higher than the SS/PBCH block, and vice versa. Figure 5.2, in the case that the value of CORESET#0 and the value of the first offset are negative, the frequency domain position of Type 0 PDCCH is lower than SS/PBCH block The number of CORESET#0 resource blocks in the embodiment of this application is CORESET The absolute value of the value of #0, and the number of offset resource blocks is the absolute value of the first offset value. Under the multiplexing condition of pattern2, the value of CORESET#0 and the value of the first offset are similar to the frequency domain position relationship of Type 0 PDCCH and SS/PBCH blocks and under the multiplexing condition of pattern3, please refer to Figure 5.3 and Figure 5.4. I won't repeat them here.
