indication information of the uplink STI and/or the STBs in the uplink STI;
indication information of STBs for sending an uplink access signal;
indication information of the STI carrying various types of STBs;
configuration information of the uplink access signal;
configuration information of the MRS, where the configuration information includes one or more of: the number of ports of the MRS, configuration information of a time/frequency domain resource of the MRS, and configuration information of a code domain resource;
configuration information of a system message;
configuration information of the message signal; and
configuration information of the STBs.
In the embodiment of the present disclosure, the time/frequency domain position of the STI is: a relative position of the STI to a radio frame boundary, or time difference between the STI and the radio frame boundary, or an STI period.
In the embodiment of the present disclosure, the time/frequency domain position information of the STBs is: a relative position of the STBs to an STI boundary or the radio frame boundary, or time difference between the STBs and the STI boundary or the radio frame boundary.
In the embodiment of the present disclosure, the indication information of the uplink/downlink STI refers to time/frequency domain position information of the STI and/or time/frequency domain position information of the STBs.
Specifically, the time/frequency domain position information of the STI includes one or more of: a relative position of the STI to a radio frame boundary, time difference between the STI and the radio frame boundary, and an STI period.
