Referring to FIG. 1, FIG. 1 is a flow chart of a random access processing method provided by an embodiment of the present invention. As shown in FIG. 1, it includes the following steps:

Step 101. Send at least two random access signals to a network side device.

The random access processing method provided by the embodiment of the present invention is mainly applied in a mobile terminal to control a random access process.

In this step, the user terminal will send at least two random access signals to the network side device during each random access process. The beam for transmitting at least two random access signals is a narrow beam or a beam having the same function as the narrow beam. In this embodiment, at least two random access signals may be sent continuously by means of beam scanning, and the manner of beam scanning and the beam loaded with the random access signals may be preconfigured. Specifically, the number of random access signals may be set according to actual needs, which is not further limited here.

Step 102: Determine random access response identification information corresponding to at least one first target random access signal according to the first configuration information, where the at least one first target random access signal is one of the at least two random access signals at least one random access signal.

In this step, each first target random access signal corresponds to a piece of random access response identification information. The above-mentioned first configuration information is configuration information preset by the protocol or configuration information sent by the network-side device, that is, the first configuration information is pre-agreed by the protocol or the network-side device indicates the first configuration information. In addition, part of the configuration information may also be pre-set by the protocol, and a part of the configuration information is indicated by the network side device.

In this embodiment, the number of the above-mentioned first target random access signal may be one or multiple, which is not further limited here.

For example, when there is one first target random access signal, it may be the first random access signal among the at least two random access signals sent, or it may be the last random access signal, or it may be any random access signal in the middle. A random access signal.

When there are at least two first target random access signals, all sent random access signals may be included, or only some random access signals may be included.

Secondly, the time point for determining the random access response identification information corresponding to the first target random access signal may be set according to actual needs. For example, the random access response identification information of each first target random access signal may be determined before the random access signal is sent; or after the first target random access signal is sent, the first target random access The random access response identification information of the signal; in addition, after all the random access signals are sent, all the first target random access signals are uniformly determined.

Step 103: According to the random access response identification information, receive random access response information in a random access response window corresponding to at least one second target random access signal, where the at least one second target random access signal includes the at least one random access signal among the at least two random access signals.

In this step, the above-mentioned at least one second target random access signal may include one or more first target random access signals, and of course may also include other random access signals, for example, through other methods (the other methods may be based on actual It needs to be set, for example, it can be determined according to other configuration information, or directly indicated by the network side device) The random access signal corresponding to the random access response identification information obtained.
