Embodiment 1

[0068] The first embodiment of the information processing method provided by the present invention is applied to a terminal, and the terminal can communicate with a base station. The preferred terminal in this embodiment may be an LTE terminal capable of implementing the LTE R8 standard and the LTE R13 standard; of course, the terminal may also be a terminal capable of implementing other communication standards, which is not limited here.

[0069] figure 1 It is a schematic diagram of the implementation flow of the first embodiment of the information processing method provided by the present invention; figure 1 As shown, the method includes:

[0070] Step 101: Detect at least two first data signals, the first data signals are sent by the base station;

[0071] Here, the first data signal is at least two of a synchronization sequence sent by the base station to the terminal, a broadcast signal such as a physical broadcast channel PBCH, and a reference signal; the synchronizat...

Embodiment 2

[0082] The second embodiment of the information processing method provided by the present invention further describes the present invention based on the foregoing first embodiment.

[0083] Before determining the first number of repetitions for the terminal to send the random access request based on the obtained first characteristic parameter, if figure 2 As shown, the method also includes:

[0084] Step 201: Obtain a first time, and the first time information is characterized as a predetermined time before the terminal determines the first number of repetitions;

[0085] Here, the first time is a certain period of time before the moment when the first number of repetitions is determined, and the certain period of time is preset. For example, presetting the first time to 2 minutes means that it is within 2 minutes before the terminal determines the first number of repetitions.

[0086] Step 202: judging whether the terminal has sent a random access request to the base stati...

Abstract

The embodiments of the invention disclose an information processing method and a terminal. The method is applied to the terminal, and the terminal can communicate with a base station. The method comprises the steps of: detecting at least two first data signals which are sent by a base station; based on the at least two first data signals, acquiring first characteristic parameters corresponding to the at least two first data signals respectively; based on the acquired first characteristic parameters, determining a first repeat number that the terminal sends a random access request; and sending the random access request to the base station according to the first repeat number. By adopting the solution, the frequency that the terminal sends a preamble can be accurately determined, and the success rate of random access of the terminal can be improved.

Description

technical field [0001] The present invention relates to information processing technology, in particular to an information processing method and a terminal. Background technique [0002] In the R8 standard of Long Term Evolution LTE, the terminal adopts a contention mechanism when performing uplink random access: when the terminal receives the system information 2 of the base station, it determines the preamble sequence information and time-frequency resource information, and at the determined time-frequency position, The terminal sends a preamble sequence to the base station side; after sending the preamble sequence to the base station side, the terminal will detect whether it has received the response information RAR sent by the base station for the preamble sequence within a time window. If it does not receive the RAR, it will consider this If random access fails for the first time, the terminal will continue to perform the above process until the access succeeds. [000...
