In the present disclosure, a random access response (RAR) signal received by the terminal at least indicates a preamble sequence corresponding to the RAR signal, or indicates sequence elements in the preamble sequence corresponding to the RAR signal.
In the present disclosure, a time/frequency domain distribution density of the uplink access signal time interval is greater than or equal to a time/frequency domain distribution density of the downlink access signal time interval.
In the present disclosure, one downlink access signal time interval corresponds to a plurality of uplink access signal time intervals.
In the present disclosure, STBs in the downlink access signal time interval are in one-to-one correspondence with STBs in the uplink access signal time interval.
In the present disclosure, the method further includes:
sending, by the terminal, an uplink access signal within a plurality of uplink access signal time intervals before the terminal receives a random access request response signal from a base station.
In the present disclosure, the method further includes:
after sending, by the terminal, an uplink random access over the uplink access signal time interval, determining a transmit port according to indication information, fed back by a base station, indicating that one or more base stations receive the uplink access signal time interval.
In the present disclosure, STBs in the downlink access signal time interval received by the terminal includes one or more of the following signals: an SS, an MSG, and an MRS.
In the present disclosure, the method further includes:
