摘要

Disclosed are a signal transmission method and device, and a computer storage, including that: a base station sends or receives a signal within a sweep time interval, an access signal time interval, which is comprised of sweep time blocks sweep time blocks. The access signal time interval includes a downlink access signal time interval and an uplink access signal time interval. The base station sends the signal over the downlink access signal time interval, and receives the signal over the uplink access signal time interval. A terminal sends or receives a signal within the access signal time interval which is comprised of the sweep time blocks. The terminal sends the signal over the uplink access signal time interval, or receives the signal over the downlink access signal time interval.

The MRS mainly performs radio resource management (RRM) measurement, channel state information obtaining, and power control, and may also be used for fine synchronization, wireless link monitoring, and beam tracking. The RRM measurement result of the MRSs of a plurality of ports may calculate the RRM parameter of a cell. If the STB carries a beam, the MRS may also be used for obtaining coarse beam or fine beam information according to different types of the carried beams. In the implementation, the MRS is often expressed using a common definition “port”, which is called the MRS port, but the port category in a common sense cannot fully cover the characteristics of the MRS. The port of the MRS may be an antenna port or a beam port, or a combined port of an antenna port and a beam port, and a plurality of beam ports may exist on one antenna port. The MRS is very flexible and the form thereof may be predefined or dynamically specified. The MRS may be a narrowband signal or a wideband signal, or may use a sparse pattern distribution, as shown in FIGS. 2A, 2B, and 2C. The MRS may implicitly carry the index information of the port or the beam. For example, the index information of the port or the beam is carried through the sequence of the MRS, the relative position of the time domain and the frequency domain of the MRS, and the like. The index and number information of the port or the beam may also be explicitly carried. For example, the index information is directly modulated on the time and frequency domain resources, and then sent.

The first type STB is in a full-signal mode, that is, the STB includes all three types of signals, and has complete functions.
