In the present disclosure, the access signal time interval is comprised of 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 terminal sends one or more uplink access signals in a STB. The one or more uplink access signals at least include any one of: a cyclic prefix (CP), a preamble, guard time (GT), and a random access message.
In the present disclosure, the random access message includes: an access control channel and access data.
In the present disclosure, the plurality of uplink access signals in the STB belong to a same terminal user or different terminal users.
In the present disclosure, sequences selected as the preambles of a plurality of uplink access signals in the STB are different.
In the present disclosure, time and frequency resource positions of the one or more uplink access signals in the STB are determined according to received time, frequency, code domain or antenna port information of a downlink signal.
In the present disclosure, a sequence of the preamble of the one or more uplink access signals in the STB is consisted of a plurality of sequence elements; and the plurality of sequence elements are repetitions of any one of the plurality of sequence elements, or different sequence elements.
In the present disclosure, the terminal simultaneously or continuously sends a plurality of uplink random access signals before the terminal receives a random access response of an uplink access signal.
