Background technique

In the current 5G standardization, a synchronization block (SS block) includes a synchronization signal and system broadcast information. When the terminal is used for initial cell selection, the default period is 20 ms, and the terminal synchronization period after the access system can be configured to be 5 ms, 10 ms, or 20 ms. Unlike LTE, the 5G standard defines multiple subcarrier spacing due to the increased bandwidth of the application. For the synchronization channel and the broadcast channel (such as shown in FIG. 1), a subcarrier spacing of 15 kHz and 30 kHz is used below 6 GHz, and a subcarrier spacing of 120 kHz and 240 kHz is used above 6 GHz.

Embodiment 1

The embodiment of the present application provides an information sending method, which is applied to a network device, and includes: sending control information in a control resource where an RMSI control resource set is located, where the control information is used to indicate at least a time-frequency resource where the remaining system information RMSI is located. s position;

The number of beams corresponding to the RMSI control resource set is the same as the number of beams corresponding to the synchronization block.

The transmitting the control information in the control resource where the RMSI control resource set is located may be to send the RMSI in a sending period of the remaining system information RMSI.

Correspondingly, the number of beams corresponding to the RMSI control resource set is the same as the number of beams corresponding to the synchronization block, and may be the number of beams corresponding to the RMSI control resource set included in the sending period of the one RMSI control resource set, and The number of beams corresponding to the sync block in one synchronization period is the same. Wherein each RMSI control resource set is associated with one sync block, and at least the space quasi-co-location QCLed.

The RMSI control resource set is similar to the synchronization channel and the broadcast channel. It also needs to implement omnidirectional coverage in the cell by means of beam scanning. Therefore, it involves how the terminal recognizes the beam direction of the RMSI control resource set and receives it correctly.

Alternatively, the RMSI is carried by the RMSI control resource set; that is, the control resource set occupied by the RMSI directly carries the remaining system information.

It is also noted that the control information is transmitted within the RMSI control resource set corresponding to at least one beam during an RMSI transmission period; wherein the spatial indication direction of each of the at least one beam may be the same or different, depending on the synchronization The direction of the beam of the block; and the time-frequency resource indicated by each beam contains the same RMSI. That is to say, there are multiple sets of RMSI control resource sets in one cycle, and each beam space pointing direction depends on the normal direction of the associated sync block, but the time-frequency resource indicated by the RMSI control resource set corresponding to each beam includes The remaining system information is the same.

Further, the transmission period of the RMSI is a positive integer multiple of the synchronization block transmission period.

For example, the number of beams corresponding to the RMSI control resource set in one cycle is the same as the number of beams corresponding to the synchronization block in one cycle, and specifically includes:

The period of the RMSI control resource set is an integer multiple of the sync block period; for example, if the sync block period is 5 ms, the period of the RMSI control resource set is an integer multiple of 5 ms; if the sync block period is 10 ms, the RMSI controls the period of the resource set It is an integer multiple of 10ms.

In addition, each RMSI control resource set is associated with one sync block, and both are at least spatial quasi-co-located QCLed.
