a processing unit, which is configured to indicate indication information of one or more uplink access signal time intervals, or indicate indication information of one or more uplink access signal time intervals and STBs in a message fed back to a terminal after the transmission unit receives an uplink access signal over the uplink access signal time interval.
In the present disclosure, the transmission unit is further configured to send a random access response message on a time/frequency domain resource and a code domain resource mapped by a synchronization signal port, a message signal port or an MRS port number.
A signal transmission device provided by another embodiment of the present disclosure is applied to a terminal, and includes:
a transmission unit, which is configured to send or receive a signal within an access signal time interval, where access signal time interval includes STBs;
The access signal time interval is an uplink access signal time interval or a downlink access signal time interval, and the terminal sends the signal over the uplink access signal time interval, or receives the signal over the downlink access signal time interval.
In the present disclosure, the access signal time interval includes a plurality of consecutive or discrete STBs.
The plurality of STBs are repeated sending of one STB, or are comprised of STBs of different content or different send ports.
In the present disclosure, the transmission unit is configured to send one or more uplink access signals in a STB.
The one or more uplink access signals at least include any one of: a CP, a preamble, GT, and a random access message.
