- the user equipment When the MF system is deployed in a scenario such as a port, a dock, or an automated production stream, the user equipment generally has a high mobility. During the movement of the user equipment, the wireless signal transmitted by the base station is easily separated by the user equipment and the base station. The object is occluded, resulting in poor quality of the wireless signal, and the user equipment may not receive it normally. On the other hand, due to the large number of user equipments, it is easy to block the wireless signal during the movement process, and the user equipment may also The data sent by the base station cannot be received normally. At this time, there is a high demand for the signal quality delivered by the base station, and the base station needs to provide better wireless coverage capability to cope with the scenario where the wireless signal quality is poor.

- Interlace is the allocation unit of the uplink resources of the MF system.
- One Interlace contains 10 PRBs (physical resource blocks), and 10 PRBs are evenly distributed over the system bandwidth. Taking 20MHz and 100PRB as an example, Interlace 0 includes 10 PRBs, namely PRB 0, PRB10, PRB20, ... PRB 90; Interlace 1 contains 10 PRBs, which are PRB1, PRB11, PRB21, ..., PRB91.
- OCC and Ncs are used to perform masking and cyclic offset operations on the root sequence, respectively, to generate different preamble sequences. In the MF system, there are 4 available OCCs, and the types of cyclic offsets available are calculated according to the configuration of Ncs: 12/Ncs.
- a "root sequence" can be defined to occupy a leader sequence that the Interlace can support: 4*12/Ncs. If Interlace is added without Interlakee's resources, Interlace resources are limited by adding a new "root sequence" until 64 users can be supported.

It should be noted that, according to the above table, when Ncs is 3/6/12 and the number of Interlaces is 2, the number of users of the preamble sequence that can be supported is 64, so there is no redundant user, so The preamble sequence of "Enhanced Overlay Mode" is not supported in this case. Then the terminal may select one of the set of preamble sequences as the preamble sequence.
- each Ncs configuration can be configured such that the number of users supported by the supported preamble sequence is extended to 96, please refer to the following table:
- Ncs 2/3/4/6/12
