Abstract
A random access method and a terminal are provided. The random access method comprises: receiving random access mechanism configuration information sent by a base station, wherein the random access mechanism configuration information includes a random access type and random access time-frequency resource information corresponding to the random access type, and the random access type includes a first random access mechanism and/or a second random access mechanism; and performing a random access process of the first random access mechanism or the second random access mechanism according to the random access mechanism configuration information.
Claims17
A random access method, comprising:
- receiving random access mechanism configuration information sent by a base station, wherein the random access mechanism configuration information comprises a random access type and random access time-frequency resource information corresponding to the random access type, and the random access type comprises a first random access mechanism and/or a second random access mechanism;
- and
- performing a random access process of the first random access mechanism or the second random access mechanism according to the random access mechanism configuration information;
- wherein in a case that the random access type comprises the first random access mechanism and the second random access mechanism, and a preamble and data of the second random access mechanism are configured in a time division multiplexing manner, the random access time-frequency resource information corresponding to the first random access mechanism and the random access time-frequency resource information corresponding to the second random access mechanism are configured by using the same sub-band and time slot.
A terminal, comprising:
- a processor, a memory connected to the processor via a bus interface and configured to store computer instructions and data used by the processor in performing operations, wherein the computer instructions are called and executed by the processor to:
- receive random access mechanism configuration information sent by a base station, wherein the random access mechanism configuration information comprises a random access type and random access time-frequency resource information corresponding to the random access type, and the random access type comprises a first random access mechanism and/or a second random access mechanism;
- and
- perform a random access process of the first random access mechanism or the second random access mechanism according to the random access mechanism configuration information;
- wherein in a case that the random access type comprises the first random access mechanism and the second random access mechanism, and a preamble and data of the second random access mechanism are configured in a time division multiplexing manner, the random access time-frequency resource information corresponding to the first random access mechanism and the random access time-frequency resource information corresponding to the second random access mechanism are configured by using the same sub-band and time slot.
